REPORT OF THE SECRETARY OF THE
SMITHSONIAN INSTITUTION
C. G. ABBOT
FOR THE YEAR ENDED JUNE 30, 1944
To the Board of Regents of the Smithsonian Institution.
GENTLEMEN: I have the honor to submit herewith my report show-
ing the activities and condition of the Smithsonian Institution and the
Government bureaus under its administrative charge during the fiscal
year ended June 30, 1944. The first 12 pages contain a summary ac-
count of the affairs of the Institution; it will again be noted that many
activities usually included in this section are missing, wartime con-
ditions having forced their suspension. Appendixes 1 to 10 give more
detailed reports of the operations of the National Museum, the Na-
tional Gallery of Art, the National Collection of Fine Arts, the
Freer Gallery of Art, the Bureau of American Ethnology, the Inter-
national Exchanges, the National Zoological Park, the Astrophysical
Observatory, which now includes the divisions of astrophysical re-
search and of radiation and organisms, the Smithsonian library, and of
the publications issued under the direction of the Institution. On
page 110 is the financial report of the executive committee of the Board
of Regents.
Change in the Secretaryship.—This will be my last report, as on
June 20, 1944, I addressed the following communication to the Board
of Regents:
Having occupied the post of Secretary of the Smithsonian Institution since
February 1928, and of Acting Secretary for one year prior to that, and having
passed the age of 72 years, I wish to resign from that office, my resignation to take
effect as of July 1, 1944.
I feel that it would be quite unfair to the Institution to continue in this re-
sponsible position when in the nature of things my capacity must gradually begin
to decline. In tendering my resignation, I wish to express my gratitude to the
Board for its kindly and helpful attitude, and my desire to be of any service
which the Board or my successor may feel disposed to suggest.
Accordingly on July 1, 1944, I ceased to be Secretary of the In-
stitution, and Dr. Alexander Wetmore, Assistant Secretary, took over
the duties of the position as Acting Secretary. I wish to record here
publicly my appreciation of the unfailing helpfulness and support
1
2 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
accorded to me by the staff of the Institution, and to bespeak for my
successor and for the Institution their continued loyalty and devoted
service.
WARTIME ACTIVITIES OF THE INSTITUTION
During another full year of war, the Institution again utilized its
capabilities to the fullest extent in aiding the Army and Navy and the
various war agencies. Its normal peacetime research and exploration
program was largely abandoned except for those projects designed
to promote better cultural relations with the other American re-
publics, and its publications were restricted almost entirely to papers
having a bearing on the war or on the other Americas. To visitors
to the Institution, these changes would not be apparent, as its visible
features—museums and art galleries—have continued to operate on
full schedule. In fact, hours of opening have been expanded to in-
clude Sundays for the benefit of the large numbers of service per-
sonnel stationed around Washington and passing through. But the
time of the staff—aside from necessary curatorial work and the
recording of observations the cessation of which would result in gaps
in the scientific record—has been devoted largely to furnishing tech-
nical information and assistance urgently needed by Army, Navy,
and war agencies.
Strategic information to Army and Navy. ace scientific staff of
the Institution and its branches includes specialists in many branches
of biology, geology, anthropology, astrophysics, engineering, and
technology, and these scientists have been called upon constantly since
Pearl Harbor to answer questions confronting Army and Navy
officials. The present war, covering as it does widely scattered
regions of the earth, many of them little known to Americans, has
required the assembling of large amounts of data on the peoples,
geography, disease-harboring insects, animals and plants, and other
features of these far-flung regions. The Smithsonian Institution has
been able to furnish, both directly and through the Ethnogeographic
Board, described below, replies to hundreds of urgent questions of this
nature, and some staff members have been in almost constant con-
sultation with Army and Navy officials. Furthermore, a number of
war-connected research projects have been assigned to the Institution,
and its laboratory facilities have been utilized from time to time for
Army and Navy investigations.
Ethnogeographic Board.—As stated in my last report, the Ethno-
geographic Board is a nongovernmental agency, set up jointly by
the Smithsonian Institution, the National Research Council, the
American Council of Learned Societies, and the Social Science Re-
search Council, to serve as a clearinghouse between the Army, Navy,
REPORT OF THE SECRETARY 3
and war agencies on the one hand, and the scientific and educational
institutions of the Nation on the other. Many urgent reports and
items of strategic information have been furnished by the Board prin-
cipally on the peoples, geography, and related features of war areas.
The offices of the Board are in the Smithsonian building, and three
members of the Institution’s staff were assigned to assist the Director,
Dr. William Duncan Strong. The Army and Navy found the ser-
vices of the Board so useful that each appointed liaison officers to
facilitate contact. ‘The Board plans to continue in operation as long
as needed during the coming fiscal year.
Inter-American Cooperation—Through invitation by other agen-
cies and through its own initiative, the Institution engaged in a
number of activities designed to promote better cultural relations with
the other American republics. Work on the monumental Handbook
of South American Indians, under the editorship of Dr. Julian H.
Steward, was advanced materially. Volume 1, “The Marginal
Tribes,” and volume 2, “The Andean Civilizations,” went to the
printer toward the close of the fiscal year, and the manuscripts of
volumes 3 and 4 were well on toward completion. The editorial work
on this project is financed by the State Department, and the printing
costs will be borne by the Bureau of American Ethnology, Smithsonian
Institution, as the Handbook will appear in the Bureau’s Bulletin
series.
In September 1943 Dr. Steward was appointed Director of the
Institute of Social Anthropology, an autonomous unit of the Bureau
of American Ethnology reporting to the Secretary, created to carry
out cooperative training in anthropological teaching and research
with the other American republics as part of the program of the
Interdepartmental Committee for Cooperation with the American
Republics. The work of the Institute in Mexico was begun in co-
operation with the Escuela Nacional de Antropologia of the Instituto
Nacional de Antropologia e Historia, and plans were pending for
work in several other American republics. Dr. Steward also served
on the Temporary Organizing Committee of the Inter-American
Society of Anthropology and Geography, which had been started on
his initiative during the previous year. Dr. Ralph L. Beals served
as secretary of the committee and editor of the quarterly journal of
the Society, Acta Americana. Paid membership in the Society from
all parts of the Americas reached a total of 800.
A valuable biological project is the publication by the Institution
of a “Checklist of the Coleopterous Insects of Mexico, Central America,
the West Indies, and South America,” by Dr. R. E. Blackwelder.
No list of this important insect group now exists, and entomologists of
all the Americas will find it indispensable in future researches. The
4 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
first and second parts appeared in print during the year, and the
third part was in press.
A number of scientists on the Institution’s staff made trips to other
American republics during the year in the furtherance of cooperative
scientific projects in biology, geology, and anthropology.
Other wartime activities —As stated above, for the benefit of mili-
tary and naval personnel and war workers the Smithsonian and
National Museum buildings have again been kept open all day on Sun-
days. To accomplish this with available funds, it was necessary to
have the buildings closed on Monday mornings. Sunday Museum
tours for service personnel were arranged in the Natural History
building through cooperation with the U. 8S. O. <A Field Collector’s
Manual in Natural History was published and distributed free on
request to Army and Navy personnel. One thousand copies each were
turned over to the Army and Navy for distribution through their own
channels.
War Committee.—The Smithsonian War Committee appointed early
in 1941, after canvassing fully all the possibilities of increasing the
Institution’s usefulness in the war and embodying the results of this
study in recommendation for action, felt that its function was fulfilled
and asked that it be dissolved. In assenting to the dissolution of the
committee, I wrote to the chairman, C. W. Mitman, as follows:
I beg to express, for myself and on behalf of the Institution, a deep sense of
the value of the work of the committee in these several years, and the feeling
that those of its recommendations which have been carried through cannot but
have been very helpful to the war effort.
SUMMARY OF THE YEAR’S ACTIVITIES OF THE BRANCHES OF THE
INSTITUTION
National Museum.—Again this year the time of the scientific staff
has been largely occupied with conferences on war problems with
Army, Navy, and war agency officials and with furnishing technical
information on requests to military and naval organizations. The
Museum buildings have again been kept open all day on Sundays for
the benefit of service personnel, and Sunday Museum tours were ar-
ranged for them in cooperation with the U. S. O. New accessions
for the year totaled 239,640 specimens, an increase of more than
9,000 over last year. Among the outstanding additions to the col-
lections were the ‘following: In anthropology, an important lot of
material from Indian sites on DeSoto’s route through the south-
eastern United States in 1539-42, a collection pertaining to the Huichol
Indians of northern Jalisco, Mexico, and an assemblage of Moro and
Indonesian brasses and Philippine metalwork presented to the Tafts
during their residence in the Philippines; in biology, 2,000 mammal
specimens from Colombia collected by Philip Hershkovitz, a bird
REPORT OF THE SECRETARY 5
collection from the same country numbering 3,281 specimens, more
than 10,000 mosquito specimens from the sanitary and medical corps
of the armed forces, a molluscan collection of 51,000 Jamaican Neri-
tidae, the valuable Chickering herbarium of 10,550 plant specimens,
and the Albert Mann diatom collection, which with the other material
on hand in this field makes the Museum diatom collection one of the
most important in the world; in geology, a number of important gems
and minerals obtained through the Roebling, Chamberlain, and Can-
field funds, 7 new meteorites, 6 of them undescribed falls, and 500
specimens of rare Paleozoic fossils collected by the curator during field
work in Mexico; in engineering, a jeep, the prototype of these vehicles
made famous by World War II, and a Winton automobile of 1903, the
first automobile to be driven across the United States; in history, a
number of Army and Navy medals and decorations of types estab-
lished during the present war. The few expeditions that were in the
field during the year were related directly or indirectly to the war.
Visitors for the year numbered 1,532,765, an increase of 177,496 over
last year; approximately 40 percent were service personnel. The
Museum published an Annual Report, 3 Bulletins, 1 Contribution from
the National Herbarium, and 14 Proceedings papers. Staff changes
included the loss by death of the curator of invertebrate paleontology,
Dr. Charles E. Resser; Dr. G. Arthur Cooper was appointed curator
to succeed him.
National Gallery of Art.—Visitors to the Gallery totaled 2,060,071
for the year, the largest attendance since its opening. Thirty percent
of the visitors were men and women in the armed services. Features
of particular interest to service personnel were the Servicemen’s
Room, which provides a place of relaxation for them, the Sunday
. evening concerts, and the special exhibitions. The Board of Trustees
was directed by the Treasury Department to assume custodianship of
all works of art and exhibition material sent to this country for various
exhibitions by the former French Government, and several officers
of the Gallery were appointed to serve as officers of the American Com-
mission for the Protection and Salvage of Artistic and Historic Mon-
uments in War Areas, the headquarters of which are located in the
Gallery building. In March 1944, at the request of the State De-
partment, the Gallery established the Inter-American Office to act
as the official Government clearinghouse for the exchange of informa-
tion concerning art activites in the American republics. The Gallery
accepted a number of gifts of paintings, prints, and drawings, in-
cluding 8 paintings and 196 prints and drawings from Lessing J.
Rosenwald. Among the 18 special exhibitions held during the year
were a number relating to war subjects. More than 72,000 people
attended the various programs conducted by the Gallery’s educational
6 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
department; these included Gallery tours, discussions of the “Picture
of the Week,” and lectures on special topics.
National Collection of Fine Arts.—The annual theeting of the
Smithsonian Art Commission was again omitted because of war con-
ditions. 'The Commission lost one member by death—Dr. Frederick P.
Keppel, a member since 1932. Four miniatures were acquired through
the Catherine Walden Myer fund. Several proffered gifts of art
works are being held for action of the Art Commission at its next
meeting. A number of paintings and other art works have been ac-
cepted by the National Collection as loans; other paintings and
miniatures belonging to the Collection have been lent to museums and
art galleries, mostly for special exhibitions. Only one painting was
purchased from the Henry Ward Ranger fund, “Fifteenth Century
French Madonna and Child,” by Harry W. Watrous. Eight special
exhibitions were held during the year, as follows: Oil paintings and
other art works by Ceferino Palencia, of Mexico; water colors of
Mexico by Walter B. Swan, of Omaha, Nebr.; miniatures by 52 artists
of the Pennsylvania Society of Miniature Painters; water colors and
block prints by Ralph H. Avery, United States Navy; paintings by
John Mix Stanley, Jane C. Stanley, and Alice Stanley Acheson; paint-
ings and other art works by the National League of American Pen
Women; “Portraits of Leading American Negro Citizens,” by Mrs.
Laura Wheeler Waring, of Philadelphia, and Mrs. Betsy Graves
Reyneau, of Washington; and mural paintings from the caves of
India and other paintings of India by Sarkis Katchadourian, of New
York City.
Freer Gallery of Art-——Additions to the collections included Chinese
bronzes, ceramics, jade, and painting; Japanese lacquer and painting;
and one Armenian manuscript. Much of the time of the staff was de-
voted to war work for several Government agencies, including Jap-
anese translations, compilation of a glossary of Chinese geographical
and topograhpical terms, and the examination of Japanese documents.
The Director attended a meeting in New York of the Committee of
the American Council of Learned Societies on Protection of Cultural
Treasures in War Areas. Visitors to the Gallery totaled 62,462 for
the year. Fifteen groups received instruction by staff members.
Bureau of American Ethnology—Emphasis on activities concerned
with Latin America has continued during the year. Dr. M. W.
Stirling, Chief of the Bureau, directed the Sixth National Geographic
Society-Smithsonian Institution expedition to Mexico, locating sev-
eral new archeological sites in southern Veracruz, Tabasco, and
Campeche. Dr. J. R. Swanton read the proof of his extensive work
on “The Indians of the Southeastern United States,” and completed
a manuscript on the much discussed Norse expeditions to America.
REPORT OF THE SECRETARY “f
Dr. Swanton retired at the end of the year after 44 years of service.
In continuation of his studies of Indian languages, Dr. J. P. Harring-
ton discovered evidence that the two South American languages
Quechua and Aymara are related to the Hokan of western North
America, the first time a linguistic relationship between North and
South America has been indicated. Dr. F. H. H. Roberts, Jr., in-
vestigated a prehistoric Indian burial near Abilene, Tex., his studies
indicating that the burial was made about 10,000 years ago. Dr.
Roberts also assembled and edited a manual, “Survival on Land and
Sea,” which was prepared for the Navy by the Ethnogeographic
Board and the staff of the Smithsonian Institution. Dr. J. H.
Steward continued work on the Handbook of South American Indians.
He was appointed Director of the Institute of Social Anthropology,
an autonomous unit of the Bureau reporting to the Secretary, on
September 1, 1943. Dr. Alfred Métraux, of the Bureau staff, was ap-
pointed Assistant Director of the above Institute on September 18,
1948. Dr. H. B. Collins, Jr., served as Assistant Director of the
Ethnogeographic Board, conducting researches connected with
regional and other information requested by the Army, Navy, and
war agencies. Dr. W. N. Fenton served as research associate of the
Board and participated in a survey of area and language teaching
in the Army Specialized Training Program and the Civil Affairs
Training Schools in American universities and colleges. Dr. H. G.
Barnett, who joined the Bureau staff in December 1943, served as
executive secretary of a committee formed under the sponsorship of
the Ethnogeographic Board for the purpose of assembling data upon
the existing state of our scientific knowledge of the Pacific island area.
Miss Frances Densmore, a collaborator of the Bureau completed a
manuscript on “Omaha Music.” The Bureau published its Annual
Report and six Bulletins during the year.
International Exchanges.—The International Exchange Service
acts as the official agency of the United States Government for the
interchange of governmental and scientific publications between this
country and all other countries. The total number of packages of
such material handled during the fiscal year was 407,764, weighing
243,180 pounds. Shipments to foreign countries continued to be
greatly curtailed by war conditions. All countries in the Western
Hemisphere received shipments as usual, but in the Eastern Hemi-
sphere, the only countries to which shipments could be made were
Great Britain and Northern Ireland, Portugal, the U. S. S. R., Union
of South Africa, India, Australia, and New Zealand. In normal
times 93 sets of United States official publications are sent abroad
through the Exchange Service. At present, however, only 58 sets
can be sent, the other 35 sets being held until after the war.

National Zoological Park.—In spite of expected difficulties in
obtaining food and supplies and those resulting from manpower
shortages, the Park and the animal collection were maintained in good
condition and continued to be used and appreciated by large numbers
of visitors. The total for the year reached 1,803,532, including a large
proportion of service personnel. Many requests for information on
biological problems were received from the Army and Navy and other
Government agencies, and numerous schools and medical and other
groups came to study the collections. Very few animals could be
obtained by purchase, but a number of desirable specimens were
received by exchange and as gifts from Army personnel and others
interested in the Park. Births and hatchings at the Park totaled 73
mammals, 180 birds, and 126 reptiles. Losses by death included the
African rhinoceros, the maned wolf, and other animals, birds, and
reptiles, including a large python that measured well over 25 feet
in length and weighed 305 pounds. At the close of the year the col-
lection totaled 2,626 animals representing 696 species and subspecies.
Astrophysical Observatory—In the division of astrophysical re-
search, secret war research problems occupied most of the time of two
members of the staff; the other members were engaged in reducing
and determining the statistical correction for the solar-constant work
of the three Smithsonian observing stations at Montezuma, Chile,
Table Mountain, Calif., and Tyrone, N. Mex., since 1939. Most of
the Director’s work consisted in the study of solar-constant variation
and associated solar changes in connection with the weather, resulting
in the publication of a paper entitled “Weather Predetermined by
Solar Variation.” As unusual weather conditions are expected dur-
ing the coming year following a predicted depression of the solar con-
stant, every effort was made to keep the three observing stations in
operation. In spite of manpower shortages, this was accomplished
by the assistance of the wives of the field directors in observing and
computing. In the division of radiation and organisms, the staff
was occupied mainly with war research projects.
THE ESTABLISHMENT
The Smithsonian Institution was created by act of Congress in
1846, according to the terms of the will of James Smithson, of Eng-
land, who in 1826 bequeathed his property to the United States of
America “to found at Washington, under the name of the Smithsonian
Institution, an establishment for the increase and diffusion of knowl-
edge among men.” In receiving the property and accepting the trust,
Congress determined that the Federal Government was without
authority to administer the trust directly, and, therefore, constituted
an “establishment” whose statutory members are “the President, the
REPORT OF THE SECRETARY 9
Vice President, the Chief Justice, and the heads of the executive
departments.”
THE BOARD OF REGENTS
The Board suffered the loss by death of one member, Senator Charles
L. McNary, of Oregon, who died on February 25, 1944. He had served
as a Senatorial regent since January 28, 1935.
The roll of regents during the fiscal year was as follows: Harlan
F. Stone, Chief Justice of the United States, Chancellor; Henry A.
Wallace, Vice President of the United States; members from the
Senate—Alben W. Barkley, Bennett Champ Clark; members from
the House of Representatives—Clarence Cannon, Foster Stearns, Ed-
ward E. Cox; citizen members—Frederic A. Delano, Washington,
D. C.; Roland S. Morris, Pennsylvania; Harvey N. Davis, New Jersey ;
Arthur H. Compton, Illinois; Vannevar Bush, Washington, D. C.; and
Frederic C. Walcott, Connecticut.
Proceedings.—The annual meeting of the Board of Regents was held
on January 14, 1944. The regents present were Chief Justice Harlan
F. Stone, Chancellor; Vice President Henry A. Wallace; Representa-
tives Clarence Cannon, Foster Stearns, and Edward E. Cox; citizen
regents Frederic A. Delano, Roland S. Morris, Harvey N. Davis,
Arthur H. Compton, and Vannevar Bush; and the Secretary, Dr.
Charles G. Abbot.
The Secretary presented his annual report covering the activities
of the parent Institution and of the several Government branches,
and including the financial report of the executive committee, for the .
fiscal year ended June 30, 1948, which was accepted by the Board.
The usual resolution authorizing the expenditure by the Secretary
of the income of the Institution for the fiscal year ending June 30,
1945, was adopted by the Board.
The Secretary stated that in order that the employees paid from
Smithsonian funds might share the same liberalized retirement ad-
vantages as the Government-paid employees in the Institution, a bill
covering this matter (S. 1558) had been introduced by Senator Bark-
ley and referred to the Senate Committee on the Civil Service.
Owing to the exigencies of wartime travel, the annual meeting of
the Smithsonian Art Commission, usually held in December, was
again omitted.
The Board formally ratified certain resolutions adopted by a mail
vote authorizing the Secretary to.execute an indenture dated March
31, 1948, by Samuel H. Kress and the Samuel H. Kress Foundation
modifying and amending an indenture dated June 29, 1939, by the
same parties, and further authorizing the Secretary to accept the |
offer of additional art objects by these parties for the collections of
the National Gallery of Art.
10 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
A resolution was adopted providing for the appointment of com-
mittees to handle matters connected with the proposed celebration
in 1946 of the centenary of the founding of the Institution.
In his special report the Secretary outlined to the regents some
of the more important wartime activities carried on by the Institution
and its several branches.
FINANCES
A statement on finances will be found in the report of the execu-
tive committee of the Board of Regents, page 110. _
TWELFTH ARTHUR LECTURE
Under the terms of the will of the late James Arthur, of New
York, the Smithsonian Institution received in 1931 a fund, part of
the income from which should be used for an annual lecture on some
aspect of the science of the sun.
The twelfth Arthur lecture was given by Secretary C. G. Abbot
on February 29, 1944, under the title “Solar Variation and Weather.”
The lecture will be published with illustrations in the Report of the
Smithsonian Institution for 1944.

Ot
REPORT OF THE SECRETARY 11
PUBLICATIONS
The Institution’s publication program has again emphasized ma-
terial pertaining to the war or to Latin America as a part of its
endeavor to make every phase of its activities serve a useful wartime
purpose.
The papers in the series Smithsonian War Background Studies
continued to be in great demand, particularly from Army and Navy
organizations and personnel. Seven numbers were issued during the
year—Nos. 13 to 19—and No. 20, on China, appeared soon after the
close of the year. A list of these, as well as other publications of the
year, will be found in appendix 10. The demand for the War Back-
ground papers continued to increase until it became necessary to make
a charge for copies requested by civilians and for large lots of copies
ordered by service organizations, while continuing the free service
distribution of single copies and small lots. Soon after the close of the
year the total number of copies of Nos. 1-20 printed by the Institution
had reached 203,500, and 211,525 additional copies have been ordered
for the Army and Navy, a grand total of nearly half a million books.
A pocket-size field collectors’ manual was published with the aim
of providing a worth-while activity for service personnel stationed in
areas not actually in the fighting zones. The manual gives detailed
directions for preparing, preserving, and packing specimens of
animals, plants, and minerals. This book also is given free to service
personnel and sold to civilians.
In the Miscellaneous Collections series, a paper intended chiefly
for the use of medical officers was issued under the title “The Feeding
Apparatus of Biting and Disease-carrying Flies: A Wartime Con-
tribution to Medical Entomology,” by R. E. Snodgrass. Several
hundred copies were made available to Army and Navy medical per-
sonnel. Also for use in connection with wartime medical problems
in the Pacific theater, it was necessary to reprint an edition of a
previous paper, “Molluscan Intermediate Hosts of the Asiatic Blood
Fluke, Schistosoma japonicum, and Species Confused with Them,” by
Paul Bartsch.
Many papers in all series of Smithsonian publications dealt with
studies in biology and anthropology of the other American republics,
as a part of the Government’s program of improving cultural rela-
tions between the Americas. In the Miscellaneous Collections a sur-
vey of existing archeological knowledge of the Andean region ap-
peared under the title “Cross Sections of New World Prehistory: A
Brief Report on the Work of the Institute of Andean Research, 1941-
1942.” by William Duncan Strong. The Smithsonian Annual Report
included a comprehensive papér on the “Past and Present Status of
the Marine Mammals of South America and the West Indies,” by
12 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Remington Kellogg. National Museum publications included a num-
ber of Proceedings papers on various phases of biology in Latin
America and a Bulletin entitled “Checklist of the Coleopterous In-
sects of Mexico, Central America, the West Indies, and South Amer-
ica,” parts 1 and 2, by Richard E. Blackwelder. This last will be an
essential tool for all future entomological work in Latin America.
In the series Contributions from the United States National Her-
barium appeared “Taxonomic Studies of Tropical American Plants,”
by C. V. Morton. The Bureau of American Ethnology published four
Bulletins on the archeology of Mexico, among them one entitled “Stone
Monuments of Southern Mexico,” by Matthew W. Stirling.
The total number of publications issued during the year was
67, and 172,027 copies of the various series were distributed.
LIBRARY
The Smithsonian library has been increasingly used by the Army,
Navy, and war agencies. In the Museum branch library alone, 520
requests for information from these sources were recorded. The
branch libraries of the Bureau of American Ethnology and the Astro-
physical Observatory were also frequently called upon, and the
staff of the Ethnogeographic Board used all the branch libraries in
search of material needed to aid the armed services and war agencies.
Through the Library of Congress, the Smithsonian library is co-
operating with the American Library Association in collecting material
to aid libraries in war areas. The gradual decline in the receipt of
publications from abroad has continued, but domestic scientific series
showed very little decline. Changes in library procedure shortened
the interval between the receipt of new publications and their avail-
ability for use. Statistics of the year’s activities show 194 new
exchanges arranged, 4,422 “wants” received, 6,673 volumes and pam-
phlets cataloged, 11,360 books and periodicals loaned, and 1,683 vol-
umes sent to the bindery.
Respectfully submitted.
C. G. Assor, Secretary.
APPENDIX 1
REPORT ON THE UNITED STATES NATIONAL MUSEUM
Str: I have the honor to submit the following report on the con-
dition and operation of the National Museum for the fiscal year
ended June 30, 1944. :
Appropriations for the maintenance and operation of the National
Museum for the year totaled $929,999, which was $37,369 more than
for the previous year.
THE MUSEUM IN WARTIME
Visitors during the year numbered 1,532,765, an increase of 177,496
over those of the previous fiscal year; approximately 40 percent of
all visitors were men and women in uniform.
Although the possibility of enemy attack on Washington became
steadily less, measures for safeguard of visitors, collections, and build-
ings were continued in force. The air-raid defense organization re-
mained in operation under the direction of the general defense co-
ordinator, F. M. Setzler, head curator of anthropology. Collections
removed from the buildings as a precaution against enemy attack
were inspected regularly, and careful guard was maintained over
them.
Asa result of a recommendation by the Smithsonian War Committee
a free guide service through the National Museum for members of
the armed forces was arranged through the U. 8. O. groups of Wash-
ington. Under the direction of F. M. Setzler a route was estab-
lished within the Natural History building and a script was pre-
pared describing the exhibits selected for the tour. Classes for in-
structing the volunteer hostesses were held on Sunday afternoons
from August 22 to October 17, 1948, and during February 1944. On
October 24 the first U. S. O. guide service for men and women in
uniform was inaugurated. Tours were conducted each Sunday at
15-minute intervals from 11 a. m. to 3:30 p. m. Each tour required
approximately 45 minutes. From October 24, 1948, to June 25, 1944,
5,825 military visitors were escorted through the building. Credit
for the success of this service is due to the excellent cooperation of
U. S. O. headquarters, to the chairman and head receptionist, Miss
Margaret Bledsoe, and to other U. S. O. hostesses.

14 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Requests for information from the various war agencies continued
to come to the staff during the year, and numerous war services
were rendered by most of the laboratories and by many individuals
on the staff,
Dr. Remington Kellogg, curator of mammals, served as chairman
of the American delegation at the International Conference on the
Regulation of Whaling in London during January 1944. At the
request of the National Research Council, Dr. Kellogg prepared text,
keys, distribution maps, and illustrations of monkeys known to be
susceptible to infection by malarial parasites to aid in studies of
malaria in man. Other services provided by the personnel of the
division of mammals to officers of special Army and Navy units
and other agencies concerned with the war included the furnishing of
information relative to the distribution and identification of mam-
mals involved in the transmission of diseases. Herbert G. Deignan,
associate curator of birds, assisted in work on maps and on geographic
names of the Far East and in a compilation of literature dealing with
parts of that area. Dr. Doris Cochran, associate curator of reptiles
and amphibians, assisted the Surgeon General’s Office in the prepara-
tion of lists of Asiatic reptiles. Personnel of the division of fishes
furnished information in response to numerous inquiries relative to
dangerous, poisonous, and useful fishes, methods of fishing, sound-
making fishes, and emergency fishing equipment. Many identifica-
tions were made in the division of insects, particularly of mosquitoes,
mites, and ectoparasites, and information was supplied on the habits of
these forms, at the request of the Army and Navy. About 1,200
specimens of insects and Acarina were specially mounted on pins and
approximately 450 slide mounts were made for use in Army and Navy
training centers throughout the country in training programs in
which health problems are involved. In addition, nearly 200 officers
assigned to malaria survey or control units, or to similar activities,
received instructions or other help from personnel of the division, and
information on the disease-bearing insects of specific foreign areas
was furnished the Division of Medical Intelligence of the Surgeon
General’s Office. At the request of the National Research Council,
Dr. Paul Bartsch, curator of mollusks, served as a member of a com-
mittee charged with the preparation of a list of helminth parasites of
the Southwest Pacific and their intermediate hosts. Dr. E. H. Walker,
assistant curator of plants, prepared an account of the emergency
food plants of the Tropics. Paul S. Conger, associate curator of the
section of diatoms, studied samples of material involved in the fouling
of ships, mines, and other marine structures. He likewise prepared a
bibliography of literature concerning the value of plankton as food.
REPORT OF THE SECRETARY 15
Services of the department of anthropology dealt with a wide variety
of subjects relating to people in the Caribbean islands, Pacific and
Indonesian areas, Oceania, Micronesia, Burma, Japan, China, the
Philippine Islands, Central America, Europe, and Africa. The in-
formation furnished included suggestions for Tropical and Arctic
clothing, and footgear for aviators, water supply, population, primi-
tive weapons, house types, degree of western influence, physical char-
acteristics, and leather products. The collections of the division were
used in a study of the resources of particular strategic geographical
areas with a view to conservation of shipping space. Dr. T. Dale
Stewart was granted a 6-month furlough to teach anatomy to Army
and Navy medical students at the Washington University School of
Medicine in St. Louis, Mo. Dr. Waldo R. Wedel, associate curator
of archeology, was detailed for special services to the Military Plan-
ning Division, Office of the Quartermaster General, War Department,
from September 1943 to March 1944. The division of physical
anthropology supplied the Office of Strategic Services with photo-
graphs of various eastern physical types. It also supplied detailed
data on average body weights of Europeans and various peoples of
the Far East to the Office of the Quartermaster General.
In the department of geology, two members of the staff, in coopera-
tion with the Geological Institute of Mexico, have continued field
studies in the economic geology of that country as a part of the war
effort. Curator W. F. Foshag spent the year on detail from the
Museum in a continuation of the supervision of surveys for strategic
minerals in Mexico. Dr. G. A. Cooper, similarly, spent 3 months in
the field in Sonora concluding studies begun last year on the stratified
rocks. The results, soon to be published, will be useful in the location
of new mineral areas. Dr. Cooper also concluded field work on the
project dealing with the subsurface geology of the Devonian rocks
of Illinois, obtaining information for use in the oil development of
that and neighboring States.
Members of the geological staff in the home office have been more
occupied than ever before in furnishing information to the various
war agencies. These services have included such diverse items as the
preparation of analyses, assisting in selecting and grading calcite for
the War Production and other Boards, editing a scientific volume for
an allied country, and furnishing information of all kinds to an ever-
increasing number of service men and women visiting the Museum.
Other services, especially from the department of engineering and
industries, have included the following:
Construction of two demonstration models of new ordnance devices
for the National Inventors’ Council; transfer of a series of model
16 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
buildings to the War Department, Corps of Engineers, Camouflage
Section; information on revolving airfoils to the Technical Data
Laboratory, Wright Field, Dayton, Ohio; furnishing photographs
for Navy training films; identification of woods; also information on
properties and uses of woods for Navy Department, War Production
Board, Foreign Economic Administration, and Inter-American De-
velopment Commission; methods of preserving specimens of dehy-
drated foods for War Food Administration; advice on disposition
of hemp produced in Kentucky to Commodity Credit Corporation ;
assistance in drawing up contract specifications involving a true lock-
stitch in sewing safety seams, to United States Maritime Commission ;
suitability of palmyra fiber as a substitute for rattan for stiff brushes
to the Navy Department; and aid in the training of document in-
spectors of Federal Bureau of Investigation in identification of various
printing processes.
COLLECTIONS
Accessions, for the year numbered 1,159 separate lots, totaling
239,640 specimens. This was an increase over those received last year
of 9,409 specimens, but a decrease of 18 in the number of accessions.
Specimens were accessioned by the five departments as follows: An-
thropology, 852; biology, 229,546; geology, 3,466; engineering and
industries, 1,888; history, 4,388. Most of the accessions were gifts
from individuals or specimens transferred from other Government
agencies. The more important of these are summarized below.
Catalog entries in all departments now total 18,098,775.
Anthropology.—The division of archeology received an important
gift of 115 lots of potsherds and other materials from various Indian
sites, many of which are on or near the presumed route of De Soto’s
expedition of 1539-42 through the southeastern United States. Two
gold-and-silver book ends, reflecting the Tiahuanacan style of archi-
tecture and sculpture, were presented by Vice President Henry A.
Wallace, who received them as gifts from the Chamber of Commerce
in Bolivia, on the occasion of his visit to La Paz. The division of
ethnology was presented with a documented collection (159 speci-
mens) pertaining to the Huichol Indians of northern Jalisco. Two
other important collections received by the division were 26 oil por-
traits of Navaho, Apache, and Pueblo Indians of Arizona and New
Mexico, painted by Carl Moon, and an assemblage of excellent ex-
amples of Moro and Indonesian brasses and Philippine metalwork,
which had been presented to the late President and Mrs. William
Howard Taft, during their residence in the Philippines.
Biology.—The largest single collection received by the division of
mammals in the past 25 years consisted of about 2,400 specimens from
REPORT OF THE SECRETARY 17
Colombia, collected by Philip Hershkovitz during his tenure of the
Walter Rathbone Bacon Traveling Scholarship of the Smithsonian
Institution. From the Fish and Wildlife Service came by transfer
the year’s second-largest mammalian accession, 624 mammals from
various North American localities. A beaked whale foetus, about 7
feet long, the largest in the National collections, is also notable.
As in the division of mammals, the largest accession of the year
to the division of birds came from Colombia. This collection com-
prised 3,281 specimens, sufficient to give the Museum a reasonably
complete representation of the bird life of northeastern Colombia.
A smaller avian collection, 85 specimens, also from Colombia, repre-
sents localities not included in the larger collection first mentioned.
Another collection included 20 species of birds hitherto unrepresented
in the study series.
As a result of exchanges with other institutions, several species '
of reptiles and amphibians hitherto unrepresented or poorly repre-
sented in the Museum have been added to the collections. Specimens
from the Great Smoky Mountains National Park, Jamaica, and Hon-
duras were received, and 60 turtles, lizards, snakes, and frogs were
contributed by Philip Hershkovitz, through the Walter Rathbone
Bacon Traveling Scholarship.
Exchanges consummated during the year brought much valuable
material, including 321 cotypes, to the division of fishes. Smaller
ichthyological collections, received as gifts, also included type ma-
terial and some specimens from type localities not previously repre-
sented in the National collections.
The vital and significant role played by entomology and entomol-
ogists in the war is reflected in the host of mosquitoes and mosquito
larvae received from the sanitary and medical corps of the armed
forces—more than 10,000 specimens. About 67,000 bees, butterflies,
and insects, including some holotype and paratype material, came as
gifts and by transfer from other Government departments.
Seven of the year’s accessions in the division of marine invertebrates
included type material. Especially noteworthy is the fact that dur-
ing the past year seven accessions, totaling 2,380 specimens, many of
them rare, were collected and donated to the Museum by men in the
armed forces.
The collection of Mexican land shells in the division of mollusks
was materially enhanced by three gifts, totaling 1,490 specimens. The
largest known single collection of Jamaican representatives of the
molluscan family Neritidae, consisting of 51,000 specimens and ac-
companying 850 microscopic slides, came as a gift.
Several valuable accessions in the form of types and cotypes came
to the helminthological collections as gifts. These included species of
18 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
the genera Ochoterenella, Choledocystus, Choricotyle, Diphylloboth-
rium, Hexostoma, Cyclocotyla, and Raillietina.
Among the 89 echinoderms accessioned were 6 undescribed species,
6 paratypes of new ophiurans, and 2 interesting abnormal starfishes.
Outstanding among the 36,240 plants received during the year was
the Chickering herbarium of approximately 10,550 specimens. This
herbarium, formed by the late John White Chickering, Jr., is a valu-
able addition as it includes material of historical importance from
collections not at all or scantily represented previously. Also in-
cluded are numerous specimens from the District of Columbia, of
which many were collected in plant habitats now destroyed. Most
of the smaller collections received came from South American or
West Indian localities. Of special importance among these were
about 2,500 specimens of bamboos, including an unusually good repre-
sentation of vegetative structures important to the field identification
of the bamboos.
The Albert Mann diatom collection, consisting of approximately
8,000 slides of mounted specimens, more than 10,000 samples of crude
diatom material, and over 200 negatives and 300 lantern slides, trans-
ferred from the Carnegie Institution of Washington, was formally
accessioned during the year. In combination with the other material
this makes the Museum collection of diatoms one of the most im-
portant in the world.
Geology.—Income from the Roebling fund, provided for the pur-
chase of important gems and minerals, was used to procure 31 gem
stones of rare quality and high exhibition value and 2 mineral acces-
sions, consisting of 4 unusually formed quartz crystals and 8 trans-
parent colorless scheelites. A beautiful pink Brazilian topaz of 34.1
carats was acquired through the Frances Lea Chamberlain fund, and
the Canfield endowment fund provided two specimens of libethenite
and acovellite. Several important single accessions came as the result
of the associate curator’s efforts to interest people in making collec-
tions for the Museum. By transfer from another Government de-
partment the division of mineralogy and petrology received specimens
of weinschenite (yttrium phosphate), representing the first occurrence
of this rare mineral in the United States.
Seven new meteorites were added to the collection, six of them being
undescribed falls.
The largest addition to the ore collection consisted of a series of
manganese and chromium ores from world-wide foreign deposits.
The most important new material received by the division of in-
vertebrate paleontology and paleobotany consisted of 500 specimens of
rare Paleozoic fossils collected by the curator during his field work
in northwestern Sonora, Mexico.
REPORT OF THE SECRETARY 19
Plaster casts of type fossils today have great scientific value, in
view of the destruction taking place in foreign museums. Such a
cast, an important English Carboniferous crinoid, the holotype and
only specimen of which was in the ill-fated Bristol Museum, was
received as a gift. Numerous types and holotypes of foraminifers,
bryozoans, mollusks, echinoids, cephalopods, and corals were welcome
additions to the collection. Important among the acquisitions of
specimens of fossil vertebrates was a composite skeleton of an extinct
antelope, as well as casts of the following: Complete skull of a curious
three-horned antelope; type specimen of a flying reptile; and skeleton
of a rare Triassic armored reptile. The ichnite collection was en-
riched by nine slabs containing the trails of Paramphibius didactylus,
once considered a vertebrate animal but now regarded as a horseshoe
crab.
Engineering and industries—From the standpoints of historical
merit and of popular appeal first honors among the acquisitions of
the year in this department are bestowed upon two automobiles. One
of these is a U. S. Army 14-ton, 4 x 4 truck, one of the first of 62 of
these vehicles built in 1940, and the prototype of these vehicles
made famous by World War II. The other is a Winton, 1903, the
first automobile to be driven across the United States, a trip that re-
quired 63 days on the road. Outstanding among the gifts to the
watercraft collection was an original kerosene-burning brass bulk-
head lantern of the first S. S. Mauretania, 1907-87, presented by Presi-
dent Franklin D. Roosevelt. The lantern now stands in the exhibi-
tion case containing the handsome model of this famous vessel pre-
“sented to the Museum by the President several years ago.
Through the Textile Color Card Association of the United States,
the textile section received the ninth edition of the Standard Color
Card, with its two supplements, the United States Arms and Serv-
ices Color Card and the United States Army Standard Thread Card.
The Association is supported by textile manufacturers and representa-
tive firms of almost every industry using color. These firms agree to
have their products match the colors included in the official standard
card, resulting in a great saving of time to consumers in obtaining
exact shades of colors in materials that are to be used together. This
standardization is especially valuable to the United States Arms and
Services, each service having an official color requirement for its uni-
forms, trimmings, badges, and similar equipment. The Standard
Thread Card is furnished by the Quartermaster General’s office to
quartermaster depots and contractors making clothing or equipage
for the United States: Army.
An important accession in the section of chemical industries was
an exhibit illustrating the chemistry and applications of refined alpha-
20 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
cellulose derived from wood pulp. Since the military services’ re-
quirements for ordnance purposes cover practically all the annual
production of cotton linters, the manufacturers of rayon found it
necessary to turn to alpha-cellulose for their raw material. The appli-
cations of the wood-pulp cellulose shown in the exhibit include rayon,
molded and laminated plastics, cellophane, artificial leather, rayon
tire-cord fabric, and electric-are welding rods.
An interesting addition to the collection of commercial furs was
a gift from Vice President Henry A. Wallace of two robes made
from strips of vicufia skins. The robes were presented to him by
Miss Rosa Prado, daughter of the President of Peri, on the occasion
of Mr. Wallace’s good-will tour.
In the division of medicine and public health the most valuable
items were added to the section of pharmacy. These included a com-
plete exhibit illustrating the manufacture and use of dried blood
plasma now effectively employed by our armed forces; a series of ob-
jects picturing the method of obtaining penicillin, the recently dis-
covered miracle-performing bacteriostatic drug; and a collection out-
lining the life history of Carl Wilhelm Scheele, the internationally
famous apothecary. To the history of medicine section was added
the first portable X-ray machine known to have been operated suc-
cessfully on a battlefield.
The outstanding accession in the section of graphic arts was a French
color print of the eighteenth century, “L’Amant Surpris,” by C. M.
Descourtis after F. Schall. This type of print, the estampe galante,
is highly prized and much sought after by collectors. Descourtis
was one of the important engravers of the period, and it is said that .
“L’Amant Surpris” is one of his masterpieces. Walter Tittle, a well-
known drypoint artist, presented the section with 19 examples of his
work, following his special exhibition in the Museum. VOKS, the
Soviet Russian Society for Cultural Relations with Foreign Countries,
gave the section six war posters produced by the hand-stencil process.’
No printing equipment is necessary in making posters of this kind,
which the Russians have developed to a high degree. Guerrilla artists
have used this method extensively in occupied territories where the
absence of printing and transportation facilities eliminates other
methods.
History.—The collection of civil, naval, marine, and military medals
and decorations was increased by specimens of several awards of
these types established during the present war. Among these were
specimens of the Air Medal, awarded to members of the armed forces
of the United States who have distinguished themselves since Sep-
tember 8, 1939, by meritorious achievement in flight. It is second only
to the Distinguished Flying Cross. They include also specimens of
REPORT OF THE SECRETARY 2)
the decorations representing the four degrees of the Legion of Merit,
namely, Chief Commander, Commander, Officer, and Legionnaire.
These decorations are for award to the personnel of armed forces of
the United States and the Philippines, and of the armed forces of
friendly foreign nations. The recipients must have distinguished
themselves by exceptionally meritorious conduct in the performance
of outstanding services since the Presidential proclamation of emer-
gency, September 8, 1939. These decorations are the first to be
founded by the United States Government for award to foreigners.
Other specimens illustrate the Merchant Marine Distinguished Serv-
ice Medal and the Mariner’s Medal. The first of these was established
for award to any person in the American Merchant Marine who on
or after September 3, 1939, “has distinguished himself * * * in
the line of duty.” The second is awarded to any seaman who, while
serving on a ship during the war period, is wounded, suffers physical
injury, or suffers through dangerous exposure as the result of an act
of an enemy of the United States.
The collection of uniforms was increased by the addition of several
United States Army and United States Military Academy uniforms
of the early part of the twentieth century. Uniforms of the types
worn by Army nurses and officers and members of the Women’s Army
Corps were received from the War Department. A series of German
and Japanese uniforms captured in Italy and the Aleutian Islands
was received as a loan from the War Department.
An interesting gift to the philatelic collection was a series of
Aguinaldo (Philippine) stamps totaling more than 2,000 specimens.
A cover franked with a 2-cent red Aguinaldo stamp postmarked
Bataan, the locality famous for the valiant fight against the Japanese
of the American forces under the leadership of Gen. Douglas Mac-
Arthur, is included. Among the stamps transferred by the Post
Office Department was a special series of 12 United States stamps
commemorating the European countries that have been overrun and
occupied by the Axis powers—Albania, Austria, Belgium, Czecho-
slovakia, Denmark, France, Greece, Luxembourg, Norway, The Nether-
lands, Poland, and Yugoslavia. Each stamp bears in color the na-
tional flag of the country concerned. The Soviet Union presented a
30-kopeck and a 3-ruble stamp showing the Russian, British, and
American flags, commemorating the recent historic conference at
Tehran. Among the stamps emanating from enemy countries that
found their way into the Museum collections were 2 Japanese stamps
commemorating the fall of Bataan and Corregidor, 11 stamps issued
by the Japanese military authorities for use in the occupation of the
Dutch Indies, and 14 varieties of Japanese stamps for the army of
22 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
occupation in the Philippine Islands. A large number of German
stamps also were received.
EXPLORATIONS AND RESEARCH
Although field explorations for the year were concerned principally
with the conduct of the war, important research. was accomplished
along many other collateral lines.
Anthropology.—During his assignment as teacher of anatomy to
Army and Navy medical students at Washington University School
of Medicine, St. Louis, Mo., studies were carried on by the curator,
Dr. T. Dale Stewart, on age and sex changes in the human skeleton.
This was possible because the skeletal collections preserved in the
university’s department of anatomy were obtained from the dis-
secting rooms and therefore were accurately identified. During the
course of this work Dr. Stewart took the opportunity also of studying
arthritic changes in the skeleton. Since arthritis is closely correlated
with age, it was hoped that the university’s identified material would
aid in the interpretation of the condition in the groups in the Museum
collections where exact age is unknown. In addition to his work at
the university, Dr. Stewart spent some time in studying Indian skele-
tons excavated in Illinois by Dr. P. F. Titterington, a St. Louis physi-
cian. Two cultural horizons are represented by these Indian re-
mains, the Hopewell and the Jersey County bluff focus of the Middle
Mississippi.
Up to the time of his death on September 5, Dr. Ale’ Hrdlicka
continued the work of analyzing his data on the human tibia. The
year also saw the publication by the Museum of the seventh and
last part of Dr. Hrdlitka’s “Catalog of Human Crania in the United
States National Museum Collections,” a work on which he had been
engaged for many years. The final part covers the non-Eskimo
people of the Northwest Coast, Alaska, and Siberia and includes
measurements of all skulls of this provenience deposited in the Na-
tional Museum as well as of many supplementary ones in various
Russian institutions. The entire series of catalogs presents measure-
ments of more than 7,500 non-White crania and has been described
as constituting “one of the most valuable sources of basic anthropo-
metric data in existence.”
Biology.—Under the auspices of the Division of Cultural Relations
of the Department of State, Ellsworth P. Killip, associate curator of
plants, visited Colombia during April, May, and June for consulta-
tions and work in botanical centers in Bogoté and Cali. In working
over the Museum’s South American material, which includes large
recent collections of plants, as well as a considerable accumulation of
REPORT OF THE SECRETARY 23
specimens received for identification in the past, Mr. Killip assembled
much valuable data for the proposed “Flora of Colombia.”
Philip Hershkovitz, holder of the Walter Rathbone Bacon Scholar-
ship for 1941-43, returned from Colombia in October, after an absence
of almost 2 years. The collection he amassed forms the largest single
accession of mammals received by the Museum during the past 25
years.
Under the W. L. Abbott fund, M. A. Carriker, Jr., continued
ornithological field work in Colombia until October. He brought to
the Museum the results of two seasons’ work, one of the finest collec-
tions of birds that has ever been made in that area.
Dr. Remington Kellogg, curator of mammals, served as chairman
of the American delegation to the International Conference on the
Regulation of Whaling held in London during January. Between
sessions of the conference he studied at the British Museum in prepara-
tion of a report on the recent porpoises. Dr. Kellogg spent part of
September at the Museum of Comparative Zodlogy examining a col-
lection of cetacean remains from Polk County, Fla. Also, at the re-
quest of the National Research Council, for the Board for the Co-
ordination of Malarial Studies, in collaboration with Major E. A.
Goldman of the Fish and Wildlife Service, Dr. Kellogg prepared
the first of a series of descriptive accounts of the kinds of monkeys
that may carry malarial infections.
The curator of birds, Dr. Herbert Friedmann, completed part 10,
the gallinaceous birds, of Ridgway’s unfinished monograph, “The
Birds of North and Middle America,” and began the revision of his
own previously completed manuscript on the falconiform birds.
H. G. Deignan, associate curator of birds, completed his monograph
on “The Birds of Northern Thailand,” now in press.
The associate curator of reptiles, Dr. Doris M. Cochran, reports
further substantial progress in her studies on South American frogs.
She also undertook to expand her popular handbook on “Poisonous
Reptiles,” Number 10 of the Smithsonian War Background Studies,
into a treatise on “Dangerous Reptiles,” nonpoisonous, as well as poi-
sonous, for the general appendix to the Smithsonian Annual Report.
Dr. Paul Bartsch, curator of mollusks, has worked in close coopera-
tion with a special committee of the National Research Council, in
preparing a list of known or suspected molluscan intermediate hosts
of human parasites.
In connection with the preparation of survivor manuals, Dr. L. P.
Schultz, curator of fishes, and Earl D. Reid, scientific aid, demonstrated
to members of the U. S. Navy the use of derris root for securing
fish for food in emergencies.
619830453
24 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Dr. Schultz also made notable progress with his studies on the
extensive material that he collected in Venezuela, finishing a report on
the Characinidae and completing manuscript for the families Gymno-
tidae, Cichlidae, Cyprinodontidae, Dasyatidae, Tetradontidae, and
Centropomidae.
The curator of insects, Dr. E. A. Chapin, made further progress
with: the manuscript embodying the results of his investigations
on the beetle genus Hippodamia and continued work on other sections
of the Coccinellidae.
Dr. R. E. Blackwelder, associate curator of insects, continuing his
work on Bulletin 185 of the National Museum, “Checklist of the Col-
eopterous Insects of Mexico, Central America, the West Indies, and
South America,” submitted the manuscript for part 3. Parts 1 and 2
were published during the year.
Austin H. Clark, curator of echinoderms, completed part 4 of Bul-
letin 82, “Monograph of the Existing Crinoids,” except for assembling
the plates. He also published “Iceland and Greenland,” the fifteenth
of the Smithsonian’s War Background Studies, and, in collaboration
with Dr. E. H. Walker, assistant curator of plants, prepared material
for the biological section of another volume of this series dealing with
the Aleutian Islands.
All divisions in the department contributed to the Navy’s “Survival
on Land and Sea,” published in December, to “A Field Collector’s
Manual in Natural History,” recently issued by the Smithsonian, and
to the preparation of nine mimeographed leaflets for distribution to
correspondents inquiring about the animal and plant life of the
Southwest Pacific.
Geology.—As in the other departments of the Museum, several
members of the staff of the department of geology are on military
detail. The researches of the head curator, Dr. R. 8. Bassler, have
been limited to three projects; first, his monographic study of Lower
Paleozoic corals; second, a paper on the giant Paleozoic Ostracoda
known as the Leperditiidae; and third, a continuation of researches
on American Ordovician crinoids and cystids contained in the
Springer collection. The manuscript and illustrations of all three
have been more than half completed.
Curator William F. Foshag was occupied the entire year in Mexico
with his supervisory work for the Geological Survey in surveys for
strategic minerals. In addition, he spent some time at the Paricutin
Volcano making observations and collecting material for the Museum
exhibition series.
E. P. Henderson completed several analyses of new meteorites.
“The Metallography of Meteoric Iron,” a monograph by Dr. Stuart H.
REPORT OF THE SECRETARY 25
Perry, associate in mineralogy, was published during the year as a
- Bulletin of the National Museum.
Dr. G. A. Cooper, in collaboration with Prof. A. S. Warthin, of
Vassar College, completed his survey of Illinois Devonian oil strata,
and, in collaboration with the Instituto Geolégico de México, con-
tinued field and laboratory studies of the geology of northwestern
Sonora. A month and a half of field work in Sonora, in association
with his Mexican colleague, Ing. A. R. V. Arellano, resulted in note-
worthy paleontological collections and considerable increase in knowl-
edge of the structure and stratigraphy of the area.
Under the Walcott fund of the Smithsonian Institution, in collabo-
ration with Drs. Myron N. Cooper and R. S. Edmundson, of the Vir-
ginia Geological Survey, Dr. Cooper made an investigation of the
relationships of the limestones that occur on the flanks of Clinch
Mountain in southwestern Virginia and northern Tennessee.
Before his untimely death Dr. Charles E. Resser was engaged in the
study of the Lower Ordovician trilobites of Vermont and adjacent
areas and was continuing his Cambrian Summary and Bibliography.
Many years of work by Drs. Walcott and Resser have gone into this
summary and bibliography, both of which when finished will be valu-
able contributions to science.
Field work in vertebrate paleontology, usually one of the best sources
of striking exhibition material, was necessarily restricted. In a
short trip to the nearby Calvert Cliffs on Chesapeake Bay, Curator
C. W. Gilmore and his assistants had the good fortune to excavate a
sirenian skeleton of Miocene age, a fossil sea cow over 10 feet long.
MISCELLANEOUS
Visitors.—The number of visitors to the Museum buildings during
the year showed an increase of 177,496 over the previous year. The
total number, 1,532,765, is, of course, far below the peacetime record
of 2,408,170 in 1937-38, but the increase does indicate a salutary up-
trend in the degree to which the National Museum exhibits and col-
lections are being viewed and studied by the people even in wartime.
August 1943 and April 1944 saw the largest number of visitors, 162,016
and 164,221, respectively, being recorded for these months. The
attendance in the four Smithsonian and Museum buildings was as
follows: Smithsonian building, 301,212; Arts and Industries building,
566,496 ; Natural History building, 493,239; Aircraft building, 171,818.
Since a considerable proportion of the visitors consisted of men and
women in the armed forces, special services were proffered this group
and every effort was made to enhance their visits. In the Natural
History building a program of Sunday docent service, for guiding
26 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
parties through the Museum, was inaugurated. A number of women
U. S. O. volunteers were especially trained to act as guides, and the
“tours” conducted by them have proved very popular. During the
period covering the last 35 Sundays of the fiscal year, over 5,000 mem-
bers of the military personnel took advantage of this guide service.
Publications and printing.—The sum of $30,000 was available dur-
ing the fiscal year for the publication of the Annual Report, Bulletins,
and Proceedings of the National Museum. Twenty publications were
issued—the Annual Report, 4 Bulletins, 1 Contribution from the
National Herbarium, and 14 Proceedings papers. A list of these
publications is given in the report on publications, appendix 10.
The distribution of volumes and separates to libraries and individ-
uals on the regular mailing lists aggregated 40,817 copies.
Special exhibits —Seventeen special exhibits were held during the
year in the foyer and adjacent space of the Natural History building,
under the auspices of various educational, scientific, recreational, and
governmental groups. In addition the department of engineering and
industries arranged 28 special displays—5 in engineering, 12 in graphic
arts, and 11 in photography.
CHANGES IN ORGANIZATION AND STAFF
There was no major change in the organization of the National
Museum, but some work has been done in allocating positions to their
proper grades under the Classification Act on the basis of the duties

APPENDIX 2
REPORT ON THE NATIONAL GALLERY OF ART
Sir: I have the honor to submit, on behalf of the Board of Trustees
of the National Gallery of Art, the seventh annual report of the Board
covering its operations for the fiscal year ended June 30, 1944. This
report.is made pursuant to the provisions of the Act of March 24, 19387
(50 Stat. 51), as amended by the public resolution of April 18, 1939
(Pub. Res. No. 9, 76th Cong.). |
ORGANIZATION AND STAFF
During the fiscal year ended June 80, 1944, the Board was comprised
of the Chief Justice of the United States, Harlan F. Stone; the Sec-
retary of State, Cordell Hull; the Secretary of the Treasury, Henry
Morgenthau, Jr.; and the Secretary of the Smithsonian Institution,
Dr. C. G. Abbot, ex officio ; and five general trustees, David K. E. Bruce,
Ferdinand Lammot Belin, Duncan Phillips, Samuel H. Kress, and
Chester Dale. Mr. Dale was elected as general trustee on November 1,
1943, to succeed Joseph E. Widener, who died on October 26, 1943.
At its annual meeting, held on February 14, 1944, the Board re-
elected David K. E. Bruce, President, and Ferdinand Lammot Belin,
Vice President, to serve for the ensuing year. The executive officers
continuing in office during the year were:
Huntington Cairns, Secretary-Treasurer.
David E. Finley, Director.
Harry A. McBride, Administrator.
Huntington Cairns, General Counsel.
John Walker, Chief Curator.
Macgill James, Assistant Director.
Donald D. Shepard continued to serve during the year as Adviser to
the Board.
During the year E. Roy Bergholz was appointed as Assistant Treas-
urer to succeed Charles Zinsner, who resigned; John A. Gilmore was
appointed as Assistant General Counsel; Hanns Swarzenski was ap-
pointed Curator of Sculpture; and Porter A. McCray was appointed
Chief of the Inter-American Office.
The Board of Trustees during the year was authorized and directed
by the Foreign Funds Control of the United States Treasury Depart-
ment, and at the request of the State Department, to assume custodian-

ship of all works of art and exhibition material sent to the United
States under the auspices of the former French Government for exhi-
bition purposes at various places in the United States, including the
World’s Fairs at New York, N. Y., and San Francisco, Calif.
On August 20, 1948, The American Commission for the Protection
and Salvage of Artistic and Historic Monuments in War Areas was
organized, and several executive officers of the Gallery were appointed
to serve as officers of the Commission. The headquarters of the Com-
mission are located in the Gallery building.
In March 1944 the Gallery, at the request of the State Department,
established the Inter-American Office. This office was created to act
as the official Government clearinghouse for the exchange of informa-
tion concerning art activities in the American Republics.
The three standing committees of the Board, provided for in the
bylaws, as constituted at the annual meeting of the Board, held Febru-
ary 14, 1944, were:
EXECUTIVE COMMITTEE
Chief Justice of the United States, Harlan F. Stone, chairman.
David K. E. Bruce, vice chairman.
Secretary of the Smithsonian Institution, Dr. C. G. Abbot.
Ferdinand Lammot Belin.
Duncan Phillips.
FINANCE COMMITTEE -
Secretary of the Treasury, Henry Morgenthau, Jr., chairman.
David K. E. Bruce, vice chairman.
Secretary of State, Cordell Hull.
Ferdinand Lammot Belin.
Samuel H. Kress.
ACQUISITIONS COMMITTEE
David K. E. Bruce, chairman.
Ferdinand Lammot Belin, vice chairman.
Duncan Phillips.
Chester Dale.
David BH. Finley, ex officio.
The permanent Government positions of the Gallery are filled
from the registers of the United States Civil Service Commission or
with its approval. On June 30, 1944, the permanent Government staff
numbered 243 employees. Since the beginning of the war, 58 mem-
bers of the staff, or approximately 25 percent, have entered the armed
services.
The operation and maintenance of the Gallery building and grounds
and the protection of the works of art have been continued through
the fiscal year 1944 at as high a standard as possible with the reduced
staffs now available. These staffs have been cut to a minimum owing
to the fact that the Gallery has desired to reduce expenditures and
REPORT OF THE SECRETARY 31
the use of manpower to the greatest possible extent during the war
period. That it has been possible to maintain a fairly high standard
is due solely to the intensive efforts, efficiency, and interest of the main-
tenance staff and the guard force. However, it will be necessary
to increase both the maintenance staff and the guard force as soon
as possible in order adequately to operate and maintain the Gallery
building and grounds and to enable the Trustees to carry out their
duties in the protection and care of the works of art in the Gallery’s
collections.
APPROPRIATIONS
For salaries and expenses for the upkeep and operation of the Na-
tional Gallery of Art, the protection and care of works of art acquired
by the Board, and all administrative expenses incident thereto as
authorized by the Act of March 24, 1937 (50 Stat. 51), and amended

ATTENDANCE
During the fiscal year ended June 30, 1944, the visitors to the
National Gallery of Art totaled 2,060,071, the largest annual attendance
since the opening of the Gallery. This compares with 1,508,081 dur-
ing the fiscal year ended June 30, 1948, or an increase of 551,990 or
36.6 percent. The increase in popularity of the Gallery is evidenced
by the fact that the average daily attendance during the fiscal year
1944 was 5,659 visitors, as compared with 4,143 for the fiscal year 1948.
On Sunday, December 21, 1943, there were 22,248 visitors, the greatest
number in any one day.
a2 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Contributing to the public’s increasing interest in the Gallery
are the evening hours on Sunday, the special exhibitions, particularly
those of wartime art, the Sunday evening concerts without charge, and
the Servicemen’s Room, which provides a place of relaxation for men
and women in the armed services. Approximately 30 percent of the
visitors to the Gallery are men and women in the armed services,
PUBLICATIONS
The Information Rooms in the Gallery continue to offer an in-
creasing variety of fine, although moderately priced, colored repro-
ductions of paintings in the Gallery’s collections, as well as post cards,
illustrated catalogs, and a general information booklet that is of
great assistance to visitors and which may be obtained without charge.
With the acquisition of the Lessing J. Rosenwald collection of prints
and drawings, a large illustrated catalog of this collection and a set
of 32 post-card reproductions of some of the prints and drawings in
the collection have been added to the publications now available.
During the past year there has been a great increase in the number
of orders for the Gallery’s publications from servicemen overseas, who
are purchasing color prints and catalogs for use in recreation rooms
at military posts all over the world. There has also been an unusual
demand from public schools throughout the United States for color
reproductions and text material descriptive of the Gallery’s collections.
These publications also are in demand in the Latin-American
republics.
WORKS OF ART STORED IN PLACE OF SAFEKEEPING
Early in January 1942 a limited number of fragile and irreplace-
able works of art in the Gallery’s collections were removed to a place
of greater safety. ‘These works, stored in a place adapted for the pur-
pose, have since been under constant guard by members of the Gal-
lery’s guard force and under supervision and inspection by a member
of the curatorial staff of the Gallery.

Commission for the Protection and Salvage of Artistic and Historic
Monuments in War Areas by providing information on damaged and

pleted in the Restorer’s studio in the Gallery with the exception of

nature that it was necessary for the work to be done in Mr. Pichetto’s
New York studio.

attended the regular lectures on special topics delivered by the educa-

titled “What To See in the National Gallery of Art—A Suggestion
for Your First Visit.” This program was accompanied by recorded
music, and more than 15,000 people attended.

the fields of Chinese, Japanese, Arabic, Persian, and Indian fine arts.
Such work involves comparative study, reading of inscriptions and
seals, written reports, and so on. In addition to the work within the
collection, reports, either oral or written, were made upon 658 objects
and 122 photographs of objects submitted for examination by their
owners, and 44 inscriptions were translated. A large part of the time
of staff members has been given to work directly contributing to the
war effort, summarized as follows:
WAR WORK
Members of the staff devoted many hours both inside and outside
regular hours to work for several Government agencies. Five
hundred forty-two typed pages-of Japanese translations were made
for the Office of Strategic Services; and a revised translation of a
REPORT OF THE SECRETARY 47
Guide to Signs and Symbols used on Chinese military maps were made
and a compilation of a glossary of Chinese geographical and topo-
graphical terms was edited and revised for the Army Map Service.
The Chinese character for “Victory” was made for an artist to be
used in connection with a publication on the United Nations. Photo-
graphs made by the Freer Gallery field staff in China were reproduced
for the Military Intelligence Division of the War Department (27
prints). For another agency, several Japanese documents were ex-
amined.
Other services have been given to various persons. For example,
63 photographs of Chinese paintings were presented to Dr. Shih-
chieh Wang, Secretary General of the People’s Council and Central
Planning Board of China and a member of the Chinese Goodwill
Mission; 557 photographs were given to members of the armed ser-
vices who visited the offices; 24 military students of the School of
Foreign Service, Georgetown University, were shown through the
Chinese exhibition galleries; and in Santa Fe, N. Mex., a lecture on
“Flower Painting in the Near and the Far East” was given by a staff
member using Freer Gallery material, for the benefit of the Indian
Service Club.

APPENDIX 5
REPORT ON THE BUREAU OF AMERICAN ETHNOLOGY
Str: I have the honor to submit the following report on the field
researches, office work, and other operations of the Bureau of Amer-
ican Ethnology during the fiscal year ended June 30, 1944, conducted
in accordance with the act of Congress of June 26, 1943, which pro-
vides “* * * for continuing ethnological researches among the
American Indians and the natives of Hawaii and the excavation and
preservation of archeologic remains. * * *”
During the fiscal year emphasis on activities concerned with Latin
America has continued.
Dr. W. D. Strong, Director of the Ethnogeographic Board, planned
to return to his duties at Columbia University soon after the close of
the fiscal year, and the work of the Board will thereafter be conducted
entirely by members of the Bureau staff.
As the war continues and the need for specialized information grows
less it is expected that the Bureau may gradually assume more of its
normal duties.
SYSTEMATIC RESEARCHES
On January 28, 1944, Dr. M. W. Stirling, Chief of the Bureau, left
Washington on the Sixth National Geographic Society-Smithsonian
Institution expedition to Mexico. The month of February was spent
in the states of Michoacan and Jalisco, where ‘a photographic record
was made of lacquer working in Uruapan and vicinity, and of pottery
making in Tlaquepaque. Ethnological pictures were made depicting
the activities and customs of the Tarascan Indians of Lake Patzcuaro.
From the beginning of March until the middle of May, an archeo-
logical reconnaissance was conducted in southern Veracruz, Tabasco,
and Campeche, with the principal objective of finding the extent of
the early La Venta culture in this area. Several new sites were located
as a result of this survey, and photographic records were made of a
number of private archeological collections.
Dr. Stirling returned to Washington on May 22, 1944.
During the year a report by Dr. Stirling, “Stone Monuments of
Southern Mexico,” was issued as Bulletin 138 of the Bureau.
During the year just passed, Dr. John R. Swanton, ethnologist,
completed the reading of proof for Bulletin 137, “The Indians of the
Southeastern United States.”
51
52 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
A study of the much discussed Norse expeditions to America was
undertaken and a manuscript completed embodying the results.
During the course of the year Dr. Swanton furnished to the Navy
Department more than 1,000 Indian tribal names and names of prom-
inent Indians, to be used for naming war vessels. Approximately 200
of these have been used.
On June 30, 1944, Dr. Swanton retired from the Bureau after
almost 44 years of service.
Dr. John P. Harrington, ethnologist, continuing his American In-
dian linguistic studies, discovered evidence suggesting that Quechua
and Aymara, the languages of the two most highly civilized groups
of aboriginal South America, are related to the Hokan stock of western
North America. This is the first time that a linguistic relationship
has been indicated between North and South America. In addition
to this Dr. Harrington has reduced the number of linguistic stocks in
South America by establishing the relationship of many groups previ-
ously considered to be separate.
Because of his unique knowledge of languages, Dr. Harrington has
been called upon daily by the Office of Censorship to translate letters
written in little-known languages from all over the world. .
During the year several short papers on linguistic subjects have been
published in scientific journals.
On July 5, 1943, Dr. Frank H. H. Roberts, Jr., senior archeologist,
went to Abilene, Tex., where he spent 5 days investigating a prehistoric
Indian burial which had been exposed 21 feet below the surface in a
bank of the Clear Fork of the Brazos River by floodwaters and which
was in danger of being washed away by a new rise. Studies of the
deposits at the site showed that the burial had been made during the
closing days of the Pleistocene or the beginning of the Early Recent
geologic period about 10,000 years ago. The skeleton was turned over
to the division of physical anthropology of the United States National
Museum, where it has received careful study and has added to the
knowledge of the physical type of the early Texas Indians.
Returning to Washington, Dr. Roberts spent the remainder of the
summer and the months of early autumn preparing contributions
to, obtaining pictures for, editing the manuscript, and reading proof
of a manual, “Survival on Land and Sea,” which was prepared for
the Publications Branch of the Office of Naval Intelligence, United
States Navy, by the Ethnogeographic Board and the staff of the
Smithsonian Institution. He later worked on a revision of this man-
ual for a second edition and also served as a consultant for a similar
manual being prepared for the Army Air Forces. During this period
he also furnished information to several other branches of the armed
services and some of the war agencies.
REPORT OF THE SECRETARY 53
Dr. Roberts also worked on his final report on the excavations at
the Lindenmeier Folsom Man site in northern Colorado, a project
completed shortly before the outbreak of the war, and also wrote a
number of articles for publication in scientific journals. On March.16,
1944, Dr. Roberts was appointed a member of the Smithsonian Insti-
tution’s Committee on Personnel Utilization and from that date until
the close of the fiscal year devoted considerable time to the activities
of that committee.
During such periods as the Chief was absent from Washington,
Dr. Roberts served as Acting Chief of the Bureau.
On September 1, 1943, Dr. Julian H. Steward, anthropologist, was
appointed Director of the Institute of Social Anthropology, an autono-
mous unit of the Bureau, reporting directly to the Secretary. His
work as editor of the Handbook of South American Indians also con-
tinued concurrently. <A brief statement on these two projects will be
found later on in this report.
At the beginning of the fiscal year Dr. Alfred Métraux, ethnologist,
was teaching in Mexico City, through an arrangement with the Na-
tional University of Mexico. He returned to duty on August 1, 1943,
and assisted Dr. Julian H. Steward in the preparation of the Hand-
book of South American Indians. Dr. Métraux was appointed Assist-
ant Director of the Institute of Social Anthropology on September 18,
1948. He completed four papers for the Handbook, and also gathered
bibliographical material for several other contributions and assembled
notes for the articles of the Handbook’s fifth volume.
During the fiscal year Dr. Henry B. Collins, Jr., ethnologist, con-
tinued his work as Assistant Director of the Ethnogeographic Board.
As in the previous year, the activities of the Board for which he was
responsible concerned research in connection with regional and other
information requested by the Army, Navy, and other war agencies.
He represented the Smithsonian Institution and the Ethnogeographic
Board as a technical adviser to the Emergency Rescue Equipment Sec-
tion of the Navy and wrote the Arctic section for the booklet “Survival
on Land and Sea.” Some 750,000 copies of this official Navy survival
manual have been distributed to the fleet and shore stations.
Dr. Collins contributed the sections on geography, history, and
anthropology for an article on the Aleutian Islands, which will be
published as one of the series of War Background Studies of the Smith-
sonian Institution.
During such time as was available, Dr. Collins continued his re-
searches on the Eskimo and the southeastern Indians.
Dr. William N. Fenton, ethnologist, continued to serve as research
associate of the Ethnogeographic Board. With the assistance of
®
54 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Miss Mae W. Tucker, he has maintained for the Ethnogeographic
Board the world file of area and language specialists, which has
grown to include more than 10,000 entries for all continents and island
areas. This file has been extensively used by the military and other
war agencies in their search for specialized personnel. From this
file a series of five studies were prepared, together with maps and in-
dexes, showing domestic sources of photographs on strategic areas
of interest particularly to the Navy Department. At the request
of the Army Specialized Training Division, the Ethnogeographic
Board commenced a survey of area and language teaching in the Army
Specialized Training Program and the Civil Affairs Training Schools
in 25 American universities and colleges. Dr. Fenton participated
in the survey, visiting 13 institutions between December 19438 and
March 1944, and since that time has been occupied in writing up ob-
servations and preparing reports for the proper offices.
In addition to this work, Dr. Fenton continued his studies on the
League of the Iroquois, translating a number of texts collected by
J.N. B. Hewitt and A. A. Goldenweiser. Dr. Fenton’s publications for
the year were: “The Last Passenger Pigeon Hunts of the Corn-
planter Senecas” (with M. H. Deardorff), and “The Requickening
Address of the Iroquois Condolence Council” (of J. N. B. Hewitt), in
the Journal of the Washington Academy of Sciences; and an obituary,
“Simeon Gibson: Iroquois Informant, 1889-1943,” in the American
Anthropologist; also several book reviews and notes in scientific and
literary journals.
Since joining the staff in December 1943, Dr. Homer G. Barnett, an-
thropologist, has served as executive secretary of a committee formed
under the sponsorship of the Ethnogeographic Board for the purpose
of assembling data upon the existing state of our scientific knowl-
edge of the Pacific Island area. The committee includes representa-
tives of the geological, geographic, linguistic, political science, and
anthropological disciplines. As executive secretary Dr. Barnett
has served chiefly as organizer and coordinator of the committee’s ac-
tions. Since some of the committee members are located outside of
Washington, considerable correspondence has been necessary as well
as meetings both in Washington and New York.
When not engaged in the above activities, Dr. Barnett has worked
on the organization of field notes on various Salishan and Northwest
Coast tribes, having in project a series of publications stressing cul- _
tural change among the Yurok, the Tsimshian, the Yakima, and the -

REPORT OF THE SECRETARY ap
INSTITUTE OF SOCIAL ANTHROPOLOGY
As stated above, Dr. Julian H. Steward, anthropologist, on Septem-
ber 1, 1948, became Director of the Institute of Social Anthropology,
an autonomous unit of the Bureau reporting directly to the Secretary.
As Dr. Steward was instructed in the official order establishing the
Institute to report to the Secretary of the Smithsonian Institution,
there are presented here brief abstracts from Dr. Steward’s reports
to Dr. Wetmore, Acting Secretary.
The Institute of Social Anthropology was first conceived in July
1942 and a project for its work was placed before the Interdepartmen-
tal Committee for Cooperation with the American Republics in Au-
gust of that year. Its stated purpose was to carry out cooperative
training in anthropological teaching and research with the other
American republics. For the fiscal year 1944, $60,000 was made avail-
able for the work of the Institute by transfer of funds from the State
Department appropriation.
In September 1943 the Director visited Mexico and established the
terms of an agreement for the work of the Institute with the authori-
ties of the Escuela Nacional de Antropologia and the Instituto
Nacional de Antropologia e Historia, submitting this to the Depart-
ment of State in late September. After some months of delay encoun-
tered in completing the agreement, Dr. George M. Foster, engaged by
the Institute as anthropologist in charge of the work in Mexico, pro-
ceeded to that country in May and started work in cooperation with
the organizations mentioned above. Dr. Donald D. Brand also repre-
sented the Institute in Mexico as cultural geographer.
No formal agreement has yet been entered into for similar work
in Peru. Nevertheless, Dr. John Gillin, appointed by the Institute in
January 1944 as anthropologist, commenced work in that country on
an informal basis. The remaining 6 months of the fiscal year were
devoted to reconnaissance and teaching at Cuzco and Trujillo.
A memorandum agreement for cooperative work in Colombia was
submitted early in 1944, but at the close of the fiscal year it had not
yet been reported out.
A new series in social anthropology entitled “Publications of the
Institute of Social Anthropology” was started with two papers, which
went to the printer just before the close of the fiscal year. No. 1 was
on “Houses and House Use of the Sierra Tarascans,” by Ralph L.
Beals, Pedro Carrasco, and Thomas McCorkle; No. 2 was entitled
“Cheran, a Sierra Tarascan Village,” by Ralph L. Beals.

56 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
HANDBOOK OF SOUTH AMERICAN INDIANS
The editing of the Handbook of South American Indians, begun
some years ago, was continued during the year by Dr. Julian H.
Steward after September 1, 1943, under his appointment as Director
of the Institute of Social Anthropology. Funds for the preparation
of the manuscript are transferred to the Smithsonian Institution from
the State Department appropriation for “Cooperation with the Ameri-
can Republics,” and the Bureau will pay the cost of publication in its
Bulletin series.
Volume 1, “The Marginal Tribes,” and volume 2, “The Andean Civil-
izations,” were completed during the year and sent to the printer. The
manuscripts of volumes 3 and 4 were nearly completed.
The Handbook is a truly cooperative project, as one-half of the
100 contributors are scientists of the other American republics.
SPECAL RESEARCHES
Miss Frances Densmore, a collaborator of the Bureau, continued
her work on the study of Indian music by writing a manuscript enti-
tled “Omaha Music,” with transcriptions of 64 songs. This manu-
script was based upon research in Nebraska in 1941 and included re-
recordings of several songs that were recorded for Miss Alice C.
Fletcher by the same singers. The date of the previous recordings
was said to have been 1887 to 1890 and the songs are included in Miss
Fletcher’s “Study of Omaha Indian Music,” published by the Peabody
Museum of Harvard University, and in “The Omaha Tribe,” by Miss
Fletcher and Francis La Flesche, in the Twenty-seventh Annual Re-
port of the Bureau. Many songs in Miss Fletcher’s work were recog-
nized by men who had not the tribal right to sing them. The present
manuscript includes old songs of Omaha military and social societies,
songs connected with the First World War, and songs of legends and
the hand game.
Miss Densmore compiled and presented to the Bureau a chronology
of her study and presentation of Indian music from 1893 to June 1944.
This chronology was based on diaries, scrapbooks, and Reports of the
Bureau. During a portion of the year she was engaged in completing
the handbook of the Smithsonian-Densmore collection of sound record-
ings of American Indian music for the National Archives.
EDITORIAL WORK AND PUBLICATIONS
The editorial work of the Bureau continued during the year under
the immediate direction of the editor, M. Helen Palmer. There were

APPENDIX 6
REPORT ON THE INTERNATIONAL EXCHANGE SERVICE
Sm: Ihave the honor to submit the following report on the activities
of the International Exchange Service for the fiscal year ended June
30, 1944.
From the appropriation “General Expenses, Smithsonian Insti-
tution” there was allocated for the expenses of the Service, $26,137.
No money was allotted to the Institution this year by the Depart-
ment of State for use in mailing packages to Argentina and Brazil,
so that the cost of such mailings had to be met from the regular
Exchange allotment. These are the only two American countries with
which there are no reciprocal arrangements for the exchange of pub-
lications under governmental frank.
The number of packages received during the year for distribution
at home and abroad was 407,764, a decrease from last year of 105,696.
These packages weighed a total of 243,180 pounds, a decrease of 5,468
pounds. This material is classified as follows:

Packages are forwarded abroad partly by freight to exchange
bureaus for distribution, and partly by mail directly to their destina-
tions. The number of boxes shipped abroad was 649, an increase over
last year of 6 boxes. Of these, 385 were for depositories of full sets of
United States governmental documents. The number of packages
sent by mail was 89,688.

60 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
War conditions have made it necessary for the Institution to suspend
shipments to many foreign countries. The countries to which
shipments were being made at the close of the year were as follows:
Eastern Hemisphere:
Great Britain and Northern Ireland.
Portugal.
Union of Soviet Socialist Republics.
Union of South Africa.
India
Australia.
New Zealand.
Western Hemisphere: All countries.
In the report for 1941 it was stated that the British Museum, Depart-
ment of Printed Books, had requested the Institution to discontinue
the sending of the full set of United States governmental documents
for the duration of the war because of the possibility of destruction
of the material through bombings of London. About the middle of
the current year the British Museum asked that the forwarding of
the Government sets be resumed as numerous requests had been re-
ceived for information contained in many of the documents. Accord-
ingly, all accumulations of official documents for the British Museum
were sent and regular transmissions have since been made.
FOREIGN DEPOSITORIES OF GOVERNMENTAL DOCUMENTS
The number of sets of United States official publications received
for transmission abroad through the International Exchange Service
is 93 (55 full and 38 partial sets). On account of war conditions it is
possible at this time to forward only 58 of these sets. The remaining
35 are being withheld for the duration.
During the year Iran and Iraq were added to the list of those coun-
tries receiving partial sets. The depository in Iran is the Ministry
of Education at Tehran, and in Iraq, Public Library at Baghdad.
The partial-set depository in Afghanistan has been changed to the
Library of the Afghan Academy, Kabul. The depository of the
partial set sent to Bengal has been changed to Library, Bengal Legis-
lature, Calcutta.
A complete list of the depositories follows. Under present condi-
tions, consignments are forwarded only to those countries listed on
tions, consignments are forwarded only to those countries listed above.

APPENDIX 7
REPORT ON THE NATIONAL ZOOLOGICAL PARK
Sir: I have the honor to submit the following report on the opera-
tions of the National Zoological Park for the fiscal year ended June
30, 1944.
The regular appropriation made by Congress was $277,130, of which
$34,732 was expended for overtime under the special legislation in
effect for this purpose.
GROUNDS, BUILDINGS, AND ENCLOSURES
The primary function of the Zoo is to maintain and exhibit its col-
lection of animals. To accomplish this under wartime conditions, it
has been necessary to limit other activities strictly to maintenance
work. No extensive improvements have been made during the year,
and because of the difficulty in obtaining critical materials, even the
maintenance work has frequently been of a temporary nature. The
gates of the Zoo have been open from daylight to dark, and many
visitors come to the Park after their working hours. In general, the
Park and the collection are in good condition and continue to be used
and appreciated by large numbers of visitors.
PERSONNEL
There has been a fairly consistent shortage of manpower in the Zoo
of about 20 percent. This has necessitated the employment of tem-
porary labor when it could be obtained, which has thrown a heavy
burden onto supervisors to whom such untrained personnel was
assigned. The additional supervisory burden has been well carried
out, with the result that the care of the Park and of the animals
has not been seriously neglected.
On December 31, Head Keeper W. H. Blackburne retired. For 17
years past the retirement age he had been retained by Executive
order, and on December 31 completed service of 53 years. He came to
the Zoo in 1891 as Keeper, and was made Head Keeper the following
year. In 1913, accompanied by Mrs. Blackburne, he went to Egypt to
bring back a collection from the zoo at Gizah. Jumbina, the National
Zoo’s large African elephant, was one of the specimens he brought
back; also the pair of cheetahs that lived in the Zoo for nearly 15

years. On his retirement the Smithsonian Institution appointed Mr.
Blackburne consultant to the Director for life. In his more than half
a century of continuous service, Mr. Blackburne saw the Zoo grow
from the original lot of 124 specimens that he brought to the Park from
the Smithsonian grounds in a wagon borrowed from the Humane
Society to its present size.
WARTIME PROBLEMS
All zoos have faced wartime difficulties in obtaining food and sup-
plies. The National Zoo, however, has received valuable assistance
from the managers of some of the large Safeway, A. and P., Giant,
and other stores, who have put aside for the Zoo trimmings from vege-
tables. These are picked up by truck each day and provide the Zoo
with greens and certain types of vegetables. Through the United
States Marshal’s Office there have been obtained considerable quan-
tities of food condemned for one reason or another as not fit for human
consumption, including several tons of peanuts, quantities of soy beans,
and other products, which have been of material aid.
ATTENDANCE
The attendance for the year was:

Although no actual tabulation was made, it was apparent that mili-
tary and naval personnel constituted a very substantial proportion of
the total number of visitors.
There has been a good attendance from various schools and groups
who have come by whatever means of transportation were available.
It is interesting to note that the number of visitors is more even
throughout the week than hitherto, although naturally the attendance
reaches its peak on Saturday afternoons, Sundays, and holidays. The
number of family picnic parties has greatly increased.
Medical groups have come to the Zoo for the purpose of studying
certain types of animals, and the Zoo office receives many requests from
the War and Navy Departments and other agencies of the Govern-
ment for information on biological problems. The Zoo continues to be
a regular study ground for art and biology classes, as well as a focal
point for inquiries about animals by mail, by telephone, and in person.
REPORT OF THE SECRETARY 69
ACQUISITION OF SPECIMENS
The animal market has naturally been restricted by the small num-
ber of shipments being made from abroad, but a moderate number of
desirable specimens have been obtained by purchase or exchange.
Among these are a trio of Dama wallabies, the two females of which
have produced young since their arrival from the San Diego Zoological
Society ; a Diana monkey, also from the San Diego Zoological Society ;
a pair of cotton-headed marmosets, a pair of scarlet cocks-of-the-rock,
and a young male jaguar.
GIFTS
Through the Army a number of interesting and valuable specimens
have been obtained. Among these are a pair of those rare birds, the
kagus, presented by the Free French Government of New Caledonia
through Lt. Gen. A. M. Patch and brought to Washington by Lt. John
H. Fulling while on leave. On a subsequent voyage, Lieutenant Full-
ing obtained for the Zoo a pair of flying phalangers and a fine carpet
python.
The Army of the U.S.S. R. presented to the Persian Gulf Command,
United States Army, through Maj. Gen. Donald H. Connolly, a young
Russian bear from the southern Caucasus. This bear, “Mischa,” was
brought from Persia to Washington under the care of Lt. A. J. Miller.
From the Medical Section, India China Wing, Air Transport Com-
mand, through Col. Don Flickinger, came a collection of Indian rep-
tiles, including cobras, kraits, Russell’s vipers and a monitor lizard.
These were brought to Washington by Corp. Wesley H. Dickinson.
Another interesting addition was a baby howling monkey.

LOSSES
Losses include the African rhinoceros, which died after 13 years in
the Zoo; a slow loris, after 5 years and 10 months; a mandrill, after
18 years and 7 months; and the maned wolf, after 10 years and 6
months.
A scarlet ibis died after 19 years 11 months; a roseate spoonbill,
after 9 years.
A large reticulated python, deposited for exhibition by Clif Wilson,
died during the winter. A cast has been made of this snake for
permanent exhibition in the United States National Museum. When
the dead snake was sent to the Museum, it measured 24 feet 8 inches.
Since 8 or 10 inches of the tail was missing, this specimen was well
over 25 feet in length, and the dead body weighed 305 pounds,
making it one of the largest snakes ever exhibited.

APPENDIX 8
REPORT ON THE ASTROPHYSICAL OBSERVATORY
Sir: I have the honor to submit the following report on the activi-
ties of the Astrophysical Observatory, including the Division of As-
trophysical Research and the Division of Radiation and Organisms,
for the fiscal year ended June 30, 1944:
DIVISION OF ASTROPHYSICAL RESEARCH
No male assistants could be retained at the three solar-constant ob-
serving stations, Montezuma, Chile, Table Mountain, Calif., and Ty-
rone, N. Mex., on account of war conditions. In this situation the
wives of the three field directors, Greeley, Warner, and Moore, have
stepped into the breach and are assisting with observing and comput-
ing. It has therefore been possible to keep the three stations in opera-
tion in this exceptionally interesting period.
As pointed out in last year’s report, the predicted march of solar
variation through 1945 indicates a large depression of solar radiation
beginning in October 1944, comparable to that which occurred 23
years earlier, beginning in 1921. Figure 1 shows that the observations
made at Montezuma observatory up to the middle of the year 1943
support thus far the trend of the prediction published in figure 14 of
volume 6 of the Annals of the Astrophysical Observatory. It is there-
fore confidently expected that the depression of the solar constant
will begin with October 1944. It is not yet possible to forecast what
exact effects this depression (similar to that of 23 years ago) may
produce in weather, but as stated in an article a generation ago by
Abbot,’ unusual weather conditions may be anticipated.
Most of the time of Mr. Hoover, Mrs. Bond, and Miss Simpson at
Washington, and part of that of Mr. Aldrich has been occupied with
the reduction and determining of the statistical corrections for the
solar-constant work of the three observing stations since 1939. Ad-
ditional types of observing, namely, polarization of the sky, and energy
spectrum observations limited to the ultraviolet region, have accumula-
ted in these recent years. Their bearing on the determination of the
solar variation is of great interest.
Mr. Aldrich has been largely occupied with special secret war
problems, and part of Dr. Abbot’s time has been thus spent also.

96 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
A major part of Dr. Abbot’s work has consisted in the study of
solar-constant variation and associated solar changes in connection
with the weather. A paper entitled “Weather Predetermined by Solar
Variation” has resulted, and appeared just at the close of the fiscal
year. In the course of these studies it was found that variations of
the areas of clouds of calcium vapor (calcium flocculi) as photographed
at the Spanish Observatory of Ebro since 1910 were associated in the
same way as solar-constant changes in predetermining the weather.
This led to an attempt to weaken the light of the sun’s disk by excessive
spectral dispersion so far as to make visible variations of the bright
lines of hydrogen or helium in the chromosphere. Doubtful evidences
of such chromospheric lines were indeed recorded, but though the
dispersion of the third order of a grating of 15,000 lines to the inch, a
battery of prisms, and a path of 55 meters of travel of the spectrum
rays were employed, the photospheric spectrum was still too bright
to disclose plainly the chromospheric lines or their variation.
’
DIVISION OF RADIATION AND ORGANISMS
As in the preceding year the work of this Division was mainly
concerned with secret problems relating to the war. However, a
paper entitled “The Influence of Light and of Carbon Dioxide on the
Respiration of Etiolated Barley Seedlings” was prepared and
published by Drs. Weintraub and Johnston.

APPENDIX 9
REPORT ON THE LIBRARY
Sir: I have the honor to submit the following report on the ac-
tivities of the Smithsonian library for the fiscal year ended June 30,
1944:
From the point of view of use, the year has been an outstanding
one. Never before in the history of the world have books played so
significant a part in the successful waging of war. As the war goes
on, the potential importance of all recorded items of human know]-
edge through integration with others becomes increasingly evident,
and often is strikingly demonstrated. It seems a far cry from the
bookstacks of a scientific library to the battlefields of Africa or the
South Pacific, but this is a scientific war, and many lives have been
saved by the exactly right bit of information about an insect, a plant,
an animal, the shore line of a far-away island, or other natural
features of strange lands found in little-known journals and docu-
ments on library shelves.
In the Smithsonian library examples of the conversion to wartime
uses of the published results of peacetime scientific investigations and
explorations might be multiplied almost indefinitely, for the library
has been increasingly used by the war agencies and by individuals in
the armed forces. In the Museum library alone, where a count of
reference questions coming from these sources was kept, there were
520 requests for information, many of which required a very consider-
able amount of research to answer. The library of the Bureau of
American Ethnology was frequently called upon, and the resources
of the Astrophysical Observatory library were often in demand, es-
pecially through the loan of scientific journals to other libraries. The
staff of the Ethnogeographic Board constantly searched all the branch
libraries for material useful to its various projects in aid of the war
agencies.
War use also accounts for the rise in the number of interlibrary
loans from 687 in 1948 to 1,363 during the year just past.
The library’s large collection of duplicates, too, has been drawn
upon by other departments of the Government, and many publications
no longer needed have been sent to fill gaps in sets in the older de-
partmental libraries or to help build up special collections in the more
recently established war agencies..
97
98 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Through the Library of Congress, the Smithsonian library is co-
operating with the American Library Association in its program of
collecting material for aid to libraries in war areas, and has already
contributed 20,806 parts of periodicals from its stock of duplicates.
The ultimate destination of some of the longer runs of journals is
known.
The library has continued to be the collection center for books for
service men and women, and by the kindness of members and friends
of the Institution, has been able to send about 300 well-selected con-
temporary books, mostly novels, to the United Nations Service
Center, and to the Public Library for distribution.
Whether in war or peace, the continuing purpose of the Smithson-
ian library with its branches is primarily to serve as a tool in the
scientific work of the Institution. The guiding principle of its
growth is not to make it a museum of fine books, but an active working
reference collection. Its main function is to put into the hands of
the scientific investigator the publication containing the information
he needs, as nearly as possible at the moment he needs it. All the
detailed and sometimes complicated processes of book selection, ac-
quisition by purchase and exchange, classification, cataloging and ar-
rangement, as well as the functioning of its reference and loan services
are planned and carried on with this ultimate objective in mind.
Many of these processes are measurable statistically, and the num-
ber of books purchased, received by exchange and gift, cataloged,
circulated, and so on, can be given, like the production figures of auto-
mobile parts. Such figures are useful indicators of material added
and work done, but beyond this, the comparison with industrial out-
put breaks down, for these library production figures cannot be finally
reduced to a countable entity like a finished automobile. On the con-
trary, the most important end-products of the library’s functioning are
diffused and intangible. They become an integral part of the scien-
tific accomplishment of the Institution itself, for they go into all its
investigations in the laboratory and the field, into the identification,
description, and exhibition of artifacts and specimens, into the books
and papers published to advance the boundaries of scientific knowl-
edge. The final test of successful library accomplishment is use.
The mere numbers of books acquired and cataloged mean little unless
the books have been discriminatingly selected for the purposes they
must serve, and well and fully cataloged so that the information they
contain can be easily found.
ACCESSIONS
Since the first abrupt drop in the receipt of publications from abroad
after war was declared, there has been a continuous small gradual
REPORT OF THE SECRETARY 99
decline in the numbers received. In 1942 there were 425 packages
delivered through the International Exchange Service, in 1943 there
were 355, and during the year just past, 340. From England, the
South American countries, New Zealand, Australia, and South Africa
the receipt of publications by mail, while somewhat fewer than before,
was steady and continuous. From other allied and neutral countries
mail arrived less regularly. It was especially gratifying to receive
several exchange sendings of considerable numbers of current publica-
tions from the Akademiia Nauk of the U. S. S. R. and its branches.
Losses of material actually shipped were extremely few.
The publication of domestic scientific serials declined very little.
The reorganized accessions division functioned smoothly in handling
both exchanges and purchases. The total number of volumes pur-
chased was 1,448, and subscriptions for 240 different periodicals were
entered.
A few of the most important purchases were:
For the Bureau of American Ethnology, William Coxe’s “Account
of the Russian Discoveries between Asia and America,” 1780; “La
Pérouse’s Voyage round the World Performed in the Years 1785, 1786,
1787, and 1788 by the Boussole and Astrolabe,” 2 volumes and atlas,
1798; ‘and the accompanying “Voyage in Search of La Pérouse...
during the Years 1791, 1792, 1793,” by J. J. Labillardiére, 1800.
For the National Collection of Fine Arts, J. J. Foster’s “Miniature
Painters, British and Foreign, with Some Account of Those Who
Practiced in America in the Eighteenth Century,” 2 volumes, 1903;
F. Norfleet’s “Saint-Mémin in Virginia, Portraits and Biographies,”
illustrated with 56 crayon portraits and 142 engravings by Saint
Mémin, 1942; T. H. Ward’s “Romney, a Biographical and Critical
Kssay, with a Catalogue Raisonné of His Works,” 2 volumes, 1904.
For the National Museum, J. B. Jackson’s “An Essay on the Inven-
tion of Engraving and Printing in Chiaroscuro as Practiced by Albert
Diirer, Hugo di Carpi, & .. .” 1754; “Bibliografiia Russkii Pe-
riodicheskoi Pechati,” 1703-1900, by N. M. Lisovskii, 1915; the third
edition of Mare Rosenberg’s “Der Goldschmiede Merkzeichen,” 4 vol-
umes, 1922-1928; Prince Nobusuke Takatsukasa’s “The Birds of Nip-
pon,” parts 1-7, 1932-1939; “The Aztec and Maya Papermakers,” by
V. W. Von Hagen, 1943.

CATALOGING
The cataloging of current material was well kept up. Some changes
in procedure and in work distribution were effective in shortening the
REPORT OF THE SECRETARY 101
interval between the receipt of new publications and the completion of
their preparation for use in the various libraries.
By way of a beginning in taking accurate stock of the large amount
of uncataloged material in the library, three small collections of
books on miscellaneous subjects, received some years ago as gifts, and
numbering 2,906 volumes in all, were roughly classified and listed on
cards,
PERSONNEL
There were a number of changes on the staff. Miss Josephine A.
McDevitt retired on November 80, 1948, after many years spent in the
service of the Institution, chiefly in the office of the International Cata-
logue of Scientific Literature, but after its discontinuance, in the
library. Miss Elizabeth Harriet Link, the librarian’s secretary, was
transferred to the Freer Gallery of Art on October 9, 1943, and Mrs.
Margaret K. Young was appointed to succeed her on November 16. On
September 1, 1943, Mrs. Margaret L. O’Keef was appointed library as-
sistant in the cataloging division. Mrs. Daisy F. Bishop resigned her
position as library assistant on January 25, 1944, and Mrs. Marie H.
Boborykine succeeded to her duties at the periodical entry desk on
March 14.
Temporary appointees were Miss Ruth Newcomb, who served as
library assistant in the Museum from August 24 to September 6, 1943,
and Mrs. Carmen G. Randall who succeeded her on September 30.
There were upward reclassifications of the positions of Miss Miriam
B. Ketchum, librarian in charge of the Bureau of American Ethnology
library, of Mrs. Mary A. Baer, librarian in charge of the Arts and In-
dustries branch of the Museum library, of Miss Marie Ruth Wenger,
in charge of cataloging in the Museum, and of Samuel Jones,
messenger.

FREER GALLERY OF ART FUND
Early in 1906, by deed of gift, Charles L. Freer, of Detroit, gave
to the Institution his collection of Chinese and other Oriental objects
of art, as well as paintings, etchings, and other works of art by Whist-
ler, Thayer, Dewing, and other artists. Later he also gave funds for
the construction of a building to house the collection, and finally in his
will probated November 6, 1919, he provided stock and securities
to the estimated value of $1,958,591.42, as an endowment fund for the
operation of the Gallery.
The above fund of Mr. Freer was almost entirely represented by 20,-
465 shares of stock in Parke, Davis & Co. As this stock advanced in
value, much of it was sold and the proceeds reinvested so that the
fund now amounts to approximately three times the original value,
or $5,881,402.17, in a selected list of securities classified later.
The invested funds of the Freer bequest are under the following
headings:

GENERAL APPENDIX
TO THE
SMITHSONIAN REPORT FOR 1944
117
ADVERTISEMENT
The object of the GrnrraL Appenprx to the Annual Report of the —
Smithsonian Institution is to furnish brief accounts of scientific dis-
covery in particular directions; reports of investigations made by
collaborators of the Institution; and memoirs of a general character
or on special topics that are of interest or value to the numerous
correspondents of the Institution.
It has been a prominent object of the Board of Regents of the
Smithsonian Institution from a very early date to enrich the annual
report required of them by law with memoirs illustrating the more
remarkable and important developments in physical and biological
discovery, as well as showing the general character of the operations
of the Institution; and, during the greater part of its history, this
purpose has been carried out largely by the publication of such papers
as would possess an interest to all attracted by scientific progress.
In 1880, induced in part by the discontinuance of an annual sum-
mary of progress which for 30 years previously had been issued by
well-known private publishing firms, the Secretary had a series of
abstracts prepared by competent collaborators, showing concisely the
prominent features of recent scientific progress in astronomy, geology,
meteorology, physics, chemistry, mineralogy, botany, zoology, and
anthropology. This latter plan was continued, though not altogether
satisfactorily, down to and including the year 1888.
In the report for 1889 a*return was made to the earlier method of
presenting a miscellaneous selection of papers (some of them original)
embracing a considerable range of scientific investigation and discus-
sion. This method has been continued in the present report for 1944.

SOLAR VARIATION AND WEATHER?
By CuHartes G. ABBOT
Former Secretary, Smithsonian Institution
[With 2 plates]
NATURE OF THE SUN
The sun is a gaseous body 860,000 miles in diameter of about 330,000
times the mass of the earth. Though so hot that neither solids nor
liquids exist in it, the force of gravity due to its enormous mass com-
presses the sun’s gaseous substance to an average density nearly 1.5
times that of water, or nearly 1,100 times that of air at sea level. This
density prevails, notwithstanding that the great temperature not only
gasifies the chemical elements, but still further subdivides them by ion-
izing them strongly. They are no longer composed of molecules, like
gaseous substances that we find in the laboratory, or even complete
atoms, for the atomic nuclei have lost some of the ions which at lower
temperatures would surround them to make up complete atoms. The
surface temperature of the sun is of the order 6,000° Centigrade, or
10,800° Fahrenheit, nearly twice as hot as the are light. Within the
sun the temperature rapidly rises, and at the sun’s center it is supposed
to be many millions of degrees. At such enormous temperatures and
with its immense surface, the sun is a tremendously powerful radiator,
so powerful that at the earth’s mean distance, 93,000,000 miles, the
sun’s average radiation in free space measures 1.94 calories per cm.? per
minute. This value is called the solar constant of radiation. It im-
plies that the earth, which is about 8,000 miles in diameter, receives
all the time from the sun the heat equivalent to a quarter of a quadril-
lion horsepower (1075/4 hp.)
SOLAR ROTATION
The sun, like the earth, rotates on an axis. The sun’s axis is not
exactly parallel to the earth’s, but inclines toward a point halfway be-
between the Pole Star and Vega at 26° from the North Pole. It has

been observed by spectroscopic methods that the angular rotation of
the sun’s surface is much faster at the Equator than near the Poles.
Adams found the following times of rotation as viewed from a fixed
star:
Solar latitude £2: 7) Sif 0° 30° 45° 60° 80°
Rotation) period = 24, 7 26. 7 28. 0 81.2 35. 3
The earth revolves about the sun in 365% days, and approximately in
the same direction that the sun rotates on its axis. Consequently the
solar rotation appears slower as viewed from the earth, which adds over
7 percent to the sun’s apparent time of rotation. The effective mean
period of solar rotation viewed from the earth may be taken as 27
days.
FACULAE AND SUNSPOTS
In a telescope, as shown in plate 1, the sun’s surface is seen to be
mottled, but at some places to show decidedly brighter areas called
faculae which are most prevalent in the neighborhood of sunspots.
Sunspots appear as darker dots on the sun’s surface, but they are
dark only by contrast. Langley compared the faculae to white-hot
steel in a converter, which made the molten steel look like chocolate.
Though sunspots appear small on the enormous disk of the sun, actually
many of them are so large that the earth, 8,000 miles in diameter,
would only occupy a corner of one. Sunspots are seldom within 10°
of the sun’s equator or more than 30° away from it. They, of course,
rotate along with the surface of the sun at such latitudes, and their
average time of rotation is about 27 days, as viewed from the earth.
SOLAR VARIATION AND SOLAR ROTATION
Sunspots are like machine guns shooting electric ions into space.
These ions plentifully strike and are captured by the earth’s atmos-
phere. With ions from other sources they make up that high-level
electrical reflecting surface in our atmosphere which causes radio rays
to bounce along the surface of the earth for thousands of miles, in-
stead of losing themselves at once into limitless space. As the sun
rotates on its axis the conical! columns of flying ions sent out from sun-
spots sweep through space. The columns from those spots which are
nearly central on the sun’s apparent disk encounter the earth for the
short time of 2 or 3 days. From certain observations we made in
March 1920, it seems that such a column of ions, 93 million miles long
between the sun and the earth, by scattering the sun’s rays sometimes
reduces the intensity of the sun beam at the earth by as much as 5
percent. Ordinarily such effects are much less, seldom exceeding 1
percent. But it is easy to see that the rotation of a spotted sun, by ionic
scattering, may produce successions of small variations of the solar
SOLAR VARIATION AND WEATHER—ABBOT 121
constant of radiation. The presence of areas of faculae, hotter and
more radiative than the adjoining solar surfaces, will also, as they
march around with the sun’s rotation, produce variations of the solar
constant.
THE EARTH’S TEMPERATURE
The earth as a planet is kept in its present approximately constant
state at the mean temperature of 14° Centigrade by the balance of its
receipt of heat from sun rays against the outgo of heat caused by the
earth’s emission to space. This earth emission arises in the invisible
long-wave rays which lie between the gamut of visible light and the
gamut of rays of very great wave length, which are used in radio
transmission. To fix ideas in terms of the centimeter, the unit of
length in the metric system, visible light rays have wave lengths
between 4 and 7 hundred-thousandths (0.00004 and 0.00007), earth rays
between 4 and 40 ten-thousandths (0.0004 and 0.0040), and radio rays
between 10 and 1 million (10 and 1,000,000) centimeters. But all of
them are of the same fundamental nature of transverse vibrations.
Since the earth’s mean temperature keeps within fairly definite
bounds because the total receipt of heat from the sun is in approxi-
mate equilibrium with the total escape of heat from the earth, it is
plain that if the sun’s contribution should change permanently, the
earth’s mean temperature would change to a new state of equilibrium.
However, the sun is so immense that no considerable general change
of this kind is to be apprehended in thousands, or even millions, of
years. Nevertheless, in what follows it will be shown that temporary
changes of the order of 1 percent do frequently occur in the sun’s
output, and that these affect weather locally so much that solar changes
must be rated as major meteorological factors.
SMITHSONIAN SOLAR-CONSTANT WORK
_ For many years the Smithsonian Institution has maintained ob-
servatories for measuring the intensity of solar rays. Our best sta-
tion is Montezuma, in the Atacama Desert of northern Chile. It
is located on a mountain 9,000 feet high, where years frequently go
by without a drop of rain. The observers must be supplied from the
city of Calama, 12 miles away, with water, as well as all other ne-
cessities. The sun shines from an unclouded sky on nearly 80 percent
of all days. As it is very trying to the nervous system to live in such
isolation under constantly cloudless skies, it is necessary to relieve the
observers at intervals of 2 or 3 years. Indeed, great loyalty to the
objects of the work, excellent ability as observers, much tact in dealing
with the people of the vicinity, and conscientious honesty and industry
are absolute requirements of the observers for the successful operation
122 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
of the station. We have been fortunate that these qualities have so
seldom been lacking in our representatives there.
Solar radiation, by being absorbed on black surfaces, is converted
into heat. Its intensity is measured by its heating effect. The ob-
servatories for measuring the solar constant of radiation have no
telescopes. To insure constant temperature surroundings, highly fa-

larly made on a moist though cloudless day.
Figure 1.—Bolographic energy curves of the solar spectrum made at Montezuma, Chile. The
vorable to exact measurements, they consist of horizontal tunnels
about 10 feet wide and 7 feet high driven into the mountain some 40
feet. We located the tunnels on a south slope in the Northern Hemi-
sphere, and on a north slope in the Southern Hemisphere. Within the
tunnel is installed a large prismatic spectroscope, whereby the sun ray
reflected into the tunnel by the coelostat outside (shown in pl. 2)
SOLAR VARIATION AND WEATHER—ABBOT 123
is cast into an intense spectrum, which comes to focus on the bo-
lometer. The bolometer, originally invented about 1880 by Dr. Samuel
P. Langley, is an electrical thermometer so sensitive that a change of
a millionth of a degree in temperature can be registered. A clockwork
causes the solar spectrum to drift slowly across the fine hairlike re-
ceiver of the bolometer, and at the same time causes a photographic
plate to drop slowly past the tiny spot of light reflected from the
mirror of the magnetic-needle system of the sensitive galvanometer
connected to the bolometer. Thus is produced in less than 10 minutes
a bolograph, or curve showing the distribution of energy of radiation in
the spectrum of the sun from far up in the ultraviolet to far down
in the infrared. Several such energy curves are taken with appro-
priate intervals during a morning as the sun rises higher and higher.
A group of them is shown in figure 1. Simultaneously with each bolo-
graph the total heating effect of the rays is measured outside the
tunnel with an instrument called the pyrheliometer (heat-of-the-sun-
meter). Also the altitude of the sun above the horizon is taken simul-
taneously with the theodolite to indicate the slant thickness of the
atmosphere. From this combination of observations it is possible
to compute the intensity of the solar radiation as it is outside our
atmosphere in free space at mean solar distance. This is the solar
constant of radiation.
DAILY VARIATIONS OF THE SOLAR CONSTANT
For 25 years the Smithsonian Institution has been collecting daily
measurements of the solar constant, when practicable, with a view to
determining the march of the variations of the sun’s output of radia-
tion. These fluctuations are small in percentage, rarely exceeding 1
percent. Figure 2 gives the still smaller variations of the monthly
mean solar-constant values, 1920-1939. It therefore requires very
great accuracy of observing to disclose and evaluate them, hampered
as we are by the superincumbent highly variable atmosphere. We are
at a disadvantage compared to astronomers who measure variable
stars, for they can compare the star investigated with other similar
stars nearby, all of which suffer equal percentage losses of light from
atmospheric hindrances. The sun is unique and can be compared
with nothing near it in the sky. One can only compare an absolute
solar measurement of today against an absolute solar measurement of
tomorrow, trusting altogether to the accurate determination of atmos-
pheric transmission on each day to make the measurements comparable.
The Institution maintains three solar-constant observatories, two
in the Northern and one in the Southern Hemisphere, all on high moun-
tains in desert lands. The following table and summary shows how
well the solar-constant daily measurements at great distances apart,

in which Mount St. Katherine figures with one of the other stations.

126 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
The weighted divergence between stations being 0.0076 calorie,
the weighted average departure of one station from the mean solar
constant derived from two stations is 0.0038 calorie.
Although it is not fair to Montezuma to suppose that the stations
are of equal merit, yet if we make that assumption, and proceed as
usual, we find the weighted mean percentage probable accidental error
of a single day of observation of the solar constant at one station
to be:
100 X 0.0088 X 0.84 1.94=0.164, or 1 of 1 percent.
In volume 6 of the Annals of the Astrophysical Observatory of the
Smithsonian Institution are contained in table 24 nearly 19,000 meas-
urements of the solar constant observed through the years 1924 to 1939.
Several thousand earlier observations of the years 1920 to 1928 are con-
tained in other publications. Figure 8 is a facsimile of a part of page
133 of the Annals, which includes the work of September 1934. The
several observing stations are distinguished by letters M, K, T, meaning
Montezuma, St. Katherine, and Table Mountain. The solar-constant
values in columns “S. C.” and “Pfd. 8. C.” are to be understood as pre-
fixed with 1.9. Thus for “50” read “1.950.” Using the result of Monte-
zuma and St. Katherine only, which are more accurate than those of
Table Mountain, there was apparently an increase in the column “Pfd.
S. C.” from the 1st to the 5th and from the 10th to the 14th of Sep-
tember, and a decrease from the 14th to the 19th. These changes had
an amplitude of the order of 0.5 to 0.9 percent, that is about 0.010 to
0.018 calorie in the solar constant of radiation.
SEQUENCES OF RISING AND OF FALLING SOLAR ACTIVITY
I give in table 2 a summary of nearly 500 of the best supported in-
stances of rise and of fall in the solar constant of radiation selected
from table 24 of volume 6 of the Annals. The table is arranged by
months and will readily be understood by an example. Thus, “Janu-
ary, Rising, 24, 12” means that a case of the solar constant rising for
a few days appeared to occur beginning January 12, 1924.
It is of interest and importance to note that the solar variation
increases in percentage toward shorter wave lengths. It is six times
as great at 3500 A. in the ultraviolet as in the total solar constant.
EFFECT OF SEQUENCES OF SOLAR CHANGE ON TERRESTRIAL
TEMPERATURES
Using this tabulation of the dates whereon sequences of rise and of
fall of the solar constant apparently began, I have sought to determine
whether such phenomena were associated with special behavior of the
SOLAR VARIATION AND WEATHER—ABBOT 127
departures from normal temperature and normal barometric pressure
at numerous cities. For this purpose I tabulated the departures, let
us say of temperature, to illustrate, for 5 days before, and for 14 days
after, each date included in table 2. Figure 4 is a facsimile of such a
tabulation of temperature departures covering the months of
January, February, and March for Washington, D. C. Two curves
of temperature departures are shown for each month. One corre-
sponds to the average influence of sequences of rising solar activ-
ity, the other to the average influence of sequences of falling solar
activity over the years 1924 to 1939. It is to be understood that these
curves show temperatures only, not solar constants. One knows only
that on the zeroth day of each line of the table a 3- to 4-day sequence
of solar changes began. The upper curves of the figure show the
average march of temperature departures at Washington in the months
of January, February, and March, each associated with 19 or more cases
of rising solar sequences, and the lower curves show the average march
of temperature departures at Washington in January, February, and
March, each associated with from 16 to 21 cases of falling solar
sequences.

CONTROL OF TEMPERATURES BY SOLAR SEQUENCES OF VARIATION
With this method of investigation clearly set forth, I now give
in figures 5 to 7 results for temperatures for all months of the year at
Washington, Albany, and Helena, and point out several characteristics
of these curves.
1. At every station, and in every month, the temperatures depart in
opposite directions, attending, respectively, rising and falling solar
activity. Thus comes about an axial symmetry of the pairs of curves
such, for instance, as subsists with one’s right hand and one’s left.
2. The march of the curves differs from month to month, and differs
for the same month from station to station, yet the right and left
symmetry always prevails.
3. The effects are large. Differences of temperature of the order
of 10 degrees Fahrenheit, or more, depend on whether a rising or a
falling sequence of solar activity preceded them many days before.
4. The effects of solar changes on temperature persist for many
days. They may surely be traced from 8 days before to 14 days after
the zeroth day of the solar sequence.
5. The coefficient of correlation of these curves for the three stations
and the 12 months of the year, and from 3 days before to 14 days
after the solar change, is found to be r= — 61.2+1.7 percent.
6. Since far-separated cities respond in a similar manner to the com-
mon system of dates given in table 2, this system of dates must have
a cosmic significance. The system of dates, in other words, betrays
an extra-terrestrial selection, harmonious to the claim that on these
dates changes in radiation occurred in the sun.
SUPPORTING EVIDENCES OF SOLAR WEATHER CONTROL
Doubters, however, may argue to the contrary as follows:
The changes claimed in solar radiation, they may say, are so small
in percentage that it is improbable that observation, however accurate,
can distinguish them from accidental errors, and from the influences of
atmospheric sources of error. May it not more probably be that the
series of dates was selected by chance? They were, indeed, dates on
which, in the average, large variations of temperature followed over
periods of 17 days, but this was merely accidental. It would then
naturally occur that sequences of dates closely following those at-
tributed to rising solar radiation would show opposite temperature
tendencies, since whatever goes up must come down. That far-sep-
arated cities would react to the same systems of dates, though not identi-
cally, is not surprising. For, as is well known, weather travels in
waves from west toward east, so that a disturbance arrived at Wash-
ington would have passed by stations to the west some days earlier.

These plausible arguments may be confuted, but it is doubtful if so
complex a proposition could be made altogether clear to the lay reader.
The simpler course is to show that these same marches of temperature,
at these same cities, are associated with another common system of dates
in another series of years, which system of dates has an undoubted solar
connection. This I shali now show.
THE SPECTROHELIOGRAPH AT THE OBSERVATORIO DEL EBRO
The eminent astronomer, Dr. George E. Hale, in his youth invented
the beautiful instrument which he named the spectroheliograph. This
device photographs the clouds of vapors of individual chemical ele-
ments, such as hydrogen, helium, iron, or calcium which float above the
sun’s surface. Hale’s spectroheliograph found instant favor all over
the world, and many observatories were equipped with it. Among
them is the Observatorio del Ebro in northern Spain, which is main-
tained by the Jesuits. Every available day from 1910 to 1987 the
monks at Ebro photographed the calcium clouds on the solar surface
with their spectroheliograph. And not only did they observe, but they
measured the areas of these clouds as well as their mean distances from
the center of the sun’s disk, and they published all the measures.
CHARACTER FIGURES OF THE SOLAR-FLOCCULUS ACTIVITY
With the help of my assistants, Mrs. Bond and Miss Simpson, I have
used these Spanish measurements of every day of observation from
1910 to 1987 to compute character figures. These represent the solar
activity of a given day as measured by the summation, according to cer-
tain weights, of the areas of the calcium clouds, or “flocculi,” photo-
* graphed that day on the sun’s disk. These character figures having
been assembled by months in 12 groups, it was seen at once that they
showed sequences of rise and of fall, for intervals of a few days each,
just as the solar-constant values do.
Going over the tables with care, I selected dates in each of the 12
months in the years from 1910 to 1937 when the best examples of se-
quences of rise and sequences of fall occurred. The period of 28
years is so long that there was no difficulty in finding enough excellent
sequences without including doubtful cases. I thus tabulated the
zeroth dates of the rising and the falling sequences of flocculus char-
acter figures for each of the 12 months covering the years 1910 to 1937.
Then the Washington temperature departures from 5 days before to
14 days after each zeroth date were tabulated in the same way as for
solar-constant correlation.

partures at Washington for the 12 months, as associated both with
solar-constant sequences and with flocculus character-figure sequences.
It is at once apparent that similar curves of temperature resulted,
but that the curves based on flocculus character figures show 2 days’
lag in phase compared to the curves based on solar constants. The two
kinds of solar change, in other words, are not exactly simultaneous.
The reader will see in the diagram that for comparison purposes the
flocculus temperature curves are all moved to the right 2 days with
respect to the solar-constant-temperature curves. This phase dif-
ference allowed for, the correlation coefficient between solar-constant
and flocculus temperature curves for Washington is r=59.7+1.9 per-
cent. It will be noted that the two systems of dates used for the two
determinations have almost nothing in common. They are spread
over two different series of years, one interval 1910 to 1937, the other
1924 to 1939. Owing to differences in days lost for cloudiness in Spain
and northern Chile, only a few of the dates in the two intervals are
adjacent. In short, in method, in the years observed, and in detail,
the two determinations have only this in common: both purport to
show the influence of changes of solar activity on Washington tem-
perature. One of the methods uses photographic phenomena univer-
sally admitted to be solar. Since the results of the two methods are
well-nigh identical, how can critics longer reasonably deny that in the
basis of the other method (the solar-constant variation) is also
a truly veridical solar phenomenon ?
I therefore claim for the Smithsonian Institution the discovery and
measurement of variations of the solar constant of radiation, and the
proof that these solar variations are major factors in the control of
terrestrial temperatures.
SOLAR SEQUENCES AND BAROMETRIC PRESSURE
We have investigated also the dependence of barometric pressure
on the solar variations tabulated in table2. I will not enter extensively
into this branch of the subject, nor show further examples of the tem-
perature effects, because I have much else to present in this lecture. I
will only draw attention to the march of barometric pressure at Denver
and Ebro (figs. 10, 11) for the 12 months, as associated with rising and
falling sequences of solar-constant changes. It will be seen that the
curves, while not so consistent as the temperature curves, already
shown, still generally display that right-and-left symmetry which has
been referred to in temperature.
POSSIBILITIES OF DETAILED LONG-RANGE FORECASTING
I now turn to the question whether these solar variations, since indi-
vidually they apparently produce major changes of weather for inter-

vals of nearly 20 days, may give hope that a method of forecasting for
many days in advance may be evolved therefrom. I have, indeed, made
a preliminary test of this possibility.
It will be apparent that after computing basic curves of the tempera-
ture effects of solar variation for a given station, it may be assumed that
when a sequence of rise of the solar constant is descried in the daily
observations, one may write down in a column for some 2 weeks there-
after the departures in temperature expected to follow this sequence of
rising solar activity. As other sequences occur, some rising, some
falling, other parallel columns of expected temperature departures are
written down on the proper dates, appropriate to each.

Pceescn 12.—Forecast and verification of. Washington temperature departures.
By the summation of all of these columns day by day, one finds an
expression of the total influence of solar variation. This summation
may go on continuously, always for as much as 10 days, in advance of
the calendar. Figure 12 gives such a summation for September and
October 1935, prepared from solar-constant basic curves for Wash-
ington and Ebro dates.
Unfortunately the solar-constant daily values of first-class quality
are too scattered as yet, with only our two first-class stations observing.
However, I have found several months in the long record of calcium-
flocculi measurements kept at Ebro when the breaks were so rare
140 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
that a fair estimate of the dates of changes in solar activity could be
made. With allowance made for the difference of 2 days in phase, the
basic curves used were those derived for Washington temperatures
' from solar-constant work. The general result was as summarized

This preliminary test, which is a forecast based on solar data alone,
gives some ground for hope that with more accurate and continuous ob-
servation of solar-constant values, when these are obtained every
single day, such solar forecasts, supplemented and corrected by the ex-
tensive knowledge of terrestrial influences now available to meteorolo-
gists, may in that combination greatly promote longer-range weather
forecasting. Since solar changes are a major weather factor it is
difficult to see how long-range weather forecasts can be made if they
are neglected as always heretofore.
THE 27-DAY PERIOD IN WASHINGTON PRECIPITATION
I now present a curious result of investigation of the sunspot rota-
tion period of 27 days in connection with the precipitation at Wash-
ington. In the year 1942 I collected values of the daily precipitation
at Washington from 1924 to 1941. These values I arranged in cycles
of 27 days. Since 27 such cycles fill 2 complete years, lacking 1 or
2 days depending on leap year, it was convenient to tabulate the values
in nine 2-year tables, and take the mean values for each of them.
I was immediately struck by the circumstance that for the mean of
every 2-year tabulation, the 11th day of the cycle in the earlier years
and the 12th day of the cycle in the later years was from 2 to 3 times
as rich in precipitation as the 6th and 7th day. The cycle, whose true
period seems to be 27.0074 days, was always taken in the phase as of
January 1-27, 1924. On taking the general mean of 243 cycles, the
characteristic of high values about the 12th day was very marked, but
other parts of the cycle also were conspicuous as high or as low in
SOLAR VARIATION AND WEATHER—ABBOT 141
precipitation. I then divided the data into three sections representa-
tive of dry years, 54 cycles; intermediate, 108 cycles; wet years, 81
cycles. The results are given in figure 13.
A VERIFIED PREDICTION ONE YEAR IN ADVANCE
In March 1943 I informed the Chief of the Weather Bureau that on
a certain list of dates the average daily precipitation would be higher
than on the remaining dates of the year. I recently tabulated the re-
sults: Using curve 3, applicable to years of intermediate precipitation,
the selected dates of 1943 were expected to show 166 times the average

rainfall of the nonselected dates. The actual ratio, for the 175 selected
dates compared to 191 nonselected (the work included December 31,
1942) was 1.58.2. The 27-day cycle has continued so consistently for
20 years at Washington that one is inclined to think it may be trusted
to hold for some years to come.
MONTHLY MEAN SOLAR CONSTANTS
We will now consider monthly mean values of the solar constant
of radiation, the variations they disclose, the periodicities found

also.

therein, and the effects of these long-term solar variations on weather.
Figure 2 gives the monthly mean solar-constant values from 1920 to
1939. The curve shows fluctuations which appear to be wholly irregu-
lar. If one asks, are these fluctuations really true changes in solar
radiation, their very magnitudes give a strong presumption that they
areso. For inthe comparison of daily values given above it was shown
that the probable error of the result of a single day of observation
from one station is but 14 of 1 percent. A monthly mean includes from
30 to 80 such values. Hence, recalling that the probable error of a
mean is the probable error of the individual value divided by the
square root of the number of values entering into the mean, we see
that the probable error of a monthly mean value is from a thirtieth
to a fiftieth of 1 percent. Yet the fluctuations in figure 2 range up to
more than 1 percent. Hence probably many of them are veridical.
PERIODICITIES IN SOLAR VARIATION
Although seemingly irregular, the march of solar variation shown
in curve A, figure 2, like the characteristic voice of the violin or of
the trumpet, comprises a long wave with many simultaneously active
shorter waves related to it by simple ratios. However in the solar
variation the simple relationships appear to be only approximate,
not quite exact, to the master cycle of 2234 years, or 273 months.
Nevertheless it is very interesting that this master period, so nearly
a least common multiple of 13 shorter ones, is approximately double
the well-known sunspot cycle of 1114 years, and thus equal to Hale’s
period of magnetic changes in sunspots. Strangely enough, though,
the sunspot cycle does not appear among the 13 submultiples of the
solar-constant master period, for no evidence of this 1114-year period
can be found in the variation of the solar constant.”*
Here are the observed periods, and their approximate relationship
to 273 months:

Curve B of figure 2 is made up by adding together the separate
influences of these 14 periodicities as they were determined from
curve A by numerical analysis. The fit of the observed curve by
the synthetic one is so good that in figure 14 of the Annals, pub-
lished several years ago, the curve B was carried on as a prophecy
of solar variation to the end of 1945. Four years of observation
have become available from Montezuma station, though only in a
provisional, not the final, reduction. Figure 14 shows a comparison
between the prophesied and actually observed solar variation. Not

only in general, but in many details, there is much similarity. We
await with very great interest the crucial test to come in the latter
part of 1944 and 1945. If the prophecy is then verified, we may
expect, as I pointed out occurred about 1922-23,3 unusual weather
conditions in 1945-46.
EFFECT OF LONGER SOLAR VARIATIONS ON WHATHER
Among the shorter periods found in solar variation, as indicated
by Smithsonian solar-constant measures, are periods of approxi-
mately 8, 984, and 1114 months. I have sought to determine how
these and the longer periods of solar variation affect temperature
and precipitation in many cities. To fix ideas I give a tabulation
(tables 3 and 4) for 8, 934, and 1114 months at Copenhagen to show
how these influences are examined.*

That there is here no progressive secular displacement of the phases of means of groups beginning at a
constant season of the year, is shown by the extended table for November-December. But groups begin-
ning at different seasons of the year do show displacement of phases with respect to one another.
I soon found that while there seemed to be some tendency to perio-
dicities in weather corresponding to the solar changes, these weather
periodicities, unlike their solar counterparts, fluctuated in phase. It
occurred to me, however, that this instability of phase is but a natural
seasonal effect for the periods of shorter duration like 8, 934, or 1144
months. For the phase of terrestrial response to a solar cause must
evidently depend on local terrestrial circumstances. For instance,
there will be a longer lag with stations under oceanic control than for
those in cloudless deserts. Pursuing this thought it occurred to me
that the phase, for example, of an 8-month period of response to solar
change in weather must be different if the solar cause occurs in
summer than if it occurs in winter. I investigated this idea for several
periods and many stations. Figure 15 shows that my surmise was
a correct one.
Hence terrestrial responses to solar periods of moderate lengths
should be expected to be in the same phases only when the solar causes
occur at the same time of the year. If a solar period of exactly 8
months existed, we must compare its terrestrial effects 2 years apart,
for then their solar causes would occur exactly at the same seasons of
the year.
I will not delay to show exactly how we make use of the calendar to
eliminate seasonal phase changes, but will content myself with show-
ing for three stations, Copenhagen, Vienna, and New Haven (see tables
3 and 4), that when this complication is properly allowed for, and when
the exact length of the solar period is determined, the terrestrial re-
sponse is proved to be exactly in phase from the year 1700 to the present
146 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
time. Figure 16 shows how necessary it is in such a long term
of years to select the exact period. Using 8 months there is but small
amplitude, even when seasonal influences are eliminated, but with

PERIODICITIES IN WEATHER
Since the 14 periods® simultaneously active in solar variation are
approximately aliquot parts of 273 months, we may anticipate that
the many weather features occurring at a station in this interval of
nearly 23 years will tend to repeat with some measure of similarity
in successive 23-year cycles. Experience shows that this influence
is more effective at some stations than at others. Figure 17 shows
what has happened at one of the most responsive stations, Peoria, IIl.
It will be seen that especially in the last half of the cycles the tendency
of features to repeat in Peoria precipitation is quite marked. Two
attempts to forecast, made in 1934 and in 1938, are shown by heavy
dotted lines, and by light full lines, respectively, in figure 17.
I have made use of this 273-month master period to predict
precipitation for some years in advance at a number of limited
regions of the United States. I reduced the prediction to a purely
routine computation, and used the percentages of normal precipi-
tation smoothed by 5-month consecutive means. Thus for March
5To them must be added the sunspot cycle of approximately 723 months. For though
it does not appear in variations of the solar constant, the ionic: bombardment of the earth
from sunspots is not negligible as a weather factor.

percentage precipitation value for January of a future year, take the
smoothed value for April 46 years previously, plus the smoothed value

works very well for some stations. Thus for Eastport, Maine, from
1935 to 1942, inclusive:

From these figures one may fairly claim that of 96 months predicted
84 were useful predictions, or a measure of success of 87 percent.
For 12 New England stations similarly evaluated, 807 were useful,
845 unsatisfactory months’ predictions.
Several years ago, at the resquest of a Colonel of Engineers I
made in this way from records of 10 stations a prediction for 3
months of the expected precipitation in the Tennessee Valley region.
My prediction of precipitation was 84 to 87 percent normal. The

THE 14 SOLAR PERIODICITIES REFLECTED INDIVIDUALLY IN
WEATHER
There is another method of making long-range weather forecasts
based on solar variation. With strict attention to the seasonal in-
fluences on phase already referred to, one may compute from monthly
SOLAR VARIATION AND WEATHER—ABBOT Lb
weather records of the past what are the effects of each of the 14
solar periodicities on temperature and on rainfall for any desired sta-
tion. Then, assuming that these influences will continue with the
same effects in future, and still paying close attention to the seasonal
changes of phase, one may add together all these effects, and also the
sunspot-cycle effect, similarly detexiiinied from records of the past,
and thus prepare a forecast for several years in the future.
With the aid of my assistant, Miss McCandlish, I have made such
forecasts of temperature and err iation for several cities in the

much so in others. Figure 21 shows one of the most successful, again
dealing with the precipitation at Peoria, Ill. We employed the pre-
cipitation records prior to 1930 to determine the outlines of the pe-
riodic terms, and then synthesized the expected precipitation through
1944. As will be seen, 10 years out of the 13 show both in phase and
amplitude considerable similarity to the event. The later years betray
an increasing tendency for the prophecy to anticipate in phase. This
may indicate that some adjustment of length of periods is desirable.

However, if one were content with 5- or 7-year predictions, such
shifts of phase could be corrected from time to time.
CONCLUSION
I have brought together many evidences which seem to indicate
that the small percentage changes observed in the solar emission of
radiation are effective factors in the domain of weather. Many others
have been published by H. H. Clayton. The solar measurements in-
volved are exceedingly difficult and require installations on high moun-
tains in desert regions, where the largest percentages of clear skies
with low wind velocities prevail. Three stations maintained by the
Smithsonian Institution are now engaged in day-to-day measure-
ments of the solar constant of radiation. On account of the variable
obstruction occasioned by the atmosphere, laden as it is with clouds,
dust, ozone, and water vapor, these three stations are insufficient
adequately to follow and record the sun’s variation. About three
times as many mountain stations, widely separated in the most cloud-
less and calm regions of the earth are needed. They could be installed
for $500,000, and operated for $250,000 per annum.®
I think there is a great probability that if such additional solar
stations were in operation they would furnish information of major
value to meteorology. I believe that with the solar data that would
then be available, and using the rich store of information regarding
terrestrial factors now familiar to meteorologists, great progress
would ensue. The neglect of solar variation, which seems to be a
major factor in weather, cannot continue if meteorology is to progress
as it should. It would be like the play “Hamlet” with Hamlet’s part
omitted.
€ Very recent developments of the research, however, give hope that another approach
to the problem not requiring additional stations may be successful.

ASTRONOMY IN A WORLD AT WAR’
By A. VIBERT DovGLas
Queen’s University
Kingston, Ontario
I
Science has advanced during the last 4 years both because and
in spite of war. Some of the sciences have made tremendous strides
as a direct result of the challenge of war necessities. Physics, chem-
istry, metallurgy, and all the branches of medical science are in this
category; some day the full story of their great achievements may
be made known. Other branches of knowledge, while far from being
unaffected by the war, have continued to advance largely in spite
of the upheavals in the life of nations and individuals which world
war inevitably brings. Astronomy is in this latter class.
Astronomy and astronomers are playing an important part in the
war chiefly along the two lines which have always presented funda-
mentally stellar problems—direction and time. But the main ad-
vances in astronomy in these last 4 years have been made in spite
of the war. It is right and fitting and indeed very encouraging that
this is the case. When so much that is of intrinsic beauty and of
fundamental value is being destroyed by war, and when so many
worthwhile activities have to cease, it is good indeed to know that
there are astronomers on this continent, and even in some parts of
Europe, and in Australia, Africa, India, and probably in Japan,
who are able to carry on the continuity of observations on stars and
starlight, sun and moon, planets and asteroids, comets and meteors.
If the continuity of observation in many branches of astronomical
work were to be completely broken, it would be an irreparable loss
to science. Thus it is with satisfaction and great admiration that
we read in the Reports of the Royal Observatory, Greenwich, that
damage done by enemy action to one of the buildings and to
the Airy transit circle has been largely made good, and observations
recommenced with that instrument upon Sun, Venus, and the stars

in the clock and azimuth lists; that parallax determinations are going
on; that solar photography and observations of chromospheric erup-
tions in Ha are continuing; and that the two Time Service Stations
have operated continuously. During this period the exhaustive work
on the solar parallax was brought to completion.
In France solar, planetary, and stellar research have been carried
on, and in Holland galactic problems, long-period variables, dark
nebulosity, and theoretical astrophysics have been under investiga-
tion even in these tragic years. In the U. S. S. R., where at least
three observatories have been destroyed and another dismantled, plans
are already made for resumption of activity and for the erection of
new observatories to further the study of latitude variations and solar
research. From two observatories east of the farthest battle front we
know that papers have been published recently on photoelectric calo-
rimetry and on color temperatures.
Similar records of observations and measurements carried on des-
pite air raids, despite reduction of staff, despite pressing war problems
and difficulties of all kinds, could be quoted from many observatories
in countries deeply involved in fighting for their very existence.
‘In these and in countries like our own—at war, but far removed
from the main theaters of conflict—there has been a very important
contribution made by astronomers in the adaptation of astronomical
observations and calculations to the problems of air ngvigation. The
Director of the Glasgow University Observatory, W. M. Smart, has
produced three books on nautical astronomy since this war began, and
under his instruction, R. A. F. pilots and cadets are learning the art
and science of navigation. Scores of astronomers, including Canadian
men well known to many of us, are doing similar work, giving all
their time, skill, and energy, and often risking their lives in the air
with student pilots, in order to impart this so necessary instruction
in air navigation,
In the Koran, it is written: “God has given you the stars to be

on his raft that he sat at the helm and “marked the skies, nor
closed in sleep his ever watchful eyes.” But navigation from the
back of a camel or from the bridge of a ship can be a relatively
leisurely performance. Not so in a modern airplane! The naviga-
tor takes a sight on a star or planet, he reads his chronometer, and
then if his calculations take him 5 minutes to perform, he and his
plane are already perhaps 25 miles away from the ascertained posi-
tion. Every minute that astronomers have been able to cut off the
time for computation of position is of the greatest value to airmen
flying over seven seas and six continents, across enemy lines, with
objectives a mere dot on the map—a railway yard, a factory, an
airfield.

Turning to the subject of time measurement, it is worthy of note
that during these war years an accuracy never before dreamed of
has been attained. It was in April 1938 that Essen described before
the Royal Astronomical Society the researches at the National Physi-
cal Laboratory which had resulted in the new quartz clock, of which
so much was hoped. This clock makes use of the properties of the
crystal oscillator, one of the most reliable and perfect mechanical
systems known to man. Essen describes quartz clocks briefly as “con-
sisting of phonic motors controlled via frequency dividers by vibrating
quartz crystals.” In a paper presented to the Royal Astronomical
Society last June, Greaves and Symms record the intercomparisons
of three Greenwich free pendulum Shortt clocks, two National Physi-
cal Laboratory quartz clocks, and three quartz clocks at the Post
Office Radio Branch Laboratories.
They analyze clock errors into three classes: (a) erratic varia-
tions in phase, (b) erratic variations in rate, (c) a combination of
phase and rate variations, producing a cumulative effect. They show
that two Shortt clocks and two quartz clocks may indicate approxi-
mately the same mean absolute second differences of relative clock
error, but the distribution of errors between the three classes is differ-
ent—the quartz clocks show very little error of (b) and (c) relative to
Shortt clocks, and errors of class (a) do not affect the long-period
performance of a clock.
The famous Shortt clocks are now known to be incapable of giving
the precision demanded, but the Astronomer Royal hastened to pay
them a deserved tribute:
Twenty years ago we had several papers dealing with the performance of
the Shortt clocks, then looked upon with great expectations. In this clock was
achieved in a simple and beautiful manner what horologists had been striving
after for years, namely, a pendulum designed solely for the purpose of beating
time whilst being called upon to perform no mechanical work. But if the subse-
quent performance of this type of clock did not fully come up to our high expec-
tations, the Shortt Free Pendulum has one thing to its everlasting credit—it
forced the astronomers to adopt the use of Mean Sidereal Time where formerly
True Sidereal Time had been adequate. During the intervening 20 years since
this type of clock was installed in many observatories, new requirements have
sprung up. In the past the main purpose of a time service was to provide absolute
time with an accuracy sufficient for navigational and surveying requirements.
But the new use of frequency standards has raised a demand for 24-hour intervals
correct to the very high accuracy of a millisecond.
It will be seen then that as absolute standards at Greenwich, Shortt clocks
have become obsolete. Our long-range predictions are now based entirely on
quartz clocks, free pendulum clocks being used only for extrapolation over an
interval of 24 hours.

Let us turn our thoughts to cosmology and recall that it was during
the first World War that Einstein’s general theory of relativity ap-
peared. Two years later, in the war year 1917, came the first sugges-
tion of an expanding universe. This was one interpretation of de
Sitter’s modification of Einstein’s cosmology, implying as it did red
shifts of the spectrum lines of faint distant objects. Incidentally, we
may turn aside to remark that while de Sitter was then working in
a Holland that had been allowed to remain neutral, his spirit is living
on in the occupied and battered Holland of this war, and he, though
dead, yet speaketh, inspiring his successors at Leiden and Amsterdam
to carry on the tradition of astrophysical research in spite of all ex-
ternal difficulties—thus Verweij has produced a theoretical discussion
of Stark effect in stellar spectra which was published in Holland and
found its way to the United States of America just before the entry
of that country into this war. Perhaps I may add that Verweij in
that paper dealt a hard blow at a paper by a McGill colleague and
myself, though I do not accept it as a knock-out blow. Further re-
search on this controversial subject is now in progress at the Dominion
Astrophysical Observatory.?
De Sitter had also deduced from Einstein’s theory the four con-
clusions which offered a hope of observational confirmation. One
of these four crucial tests was whether radiant energy passing close
to a body with an intense gravitational field surrounding it, would be
deflected in accordance with Newton’s law of gravitation or with Ein-
stein’s modification of that law. It was Prof. A. S. Eddington who
realized the great importance of making this test at the first favor-
able opportunity, namely, at the time of the total solar eclipse which
was to occur on May 29, 1919, with the Hyades as background. War
or no war, all the plans and preparations were pushed ahead and thus
it was that when the eventful day arrived, even though the Treaty of
Versailles had not yet been signed, two British expeditions were in
readiness to take the crucial photographs. I often reread the passage
written by a learned mathematician and philosopher in which he
described the meeting of the Royal Society when the results of these
eclipse expeditions were announced, verifying as they did the theory
of Einstein:
The whole atmosphere of tense interest was exactly that of the Greek drama;
we were the chorus commenting on the decree of destiny as disclosed in the
development of a supreme incident. There was dramatic quality in the very
staging ;—the traditional ceremonial, and in the background the picture of
Newton to remind us that the greatest of scientific generalisations was now, after
2? Recent work at the D. A. O. points to a confirmation of the work of Foster and Douglas
on the interpretation of helium profiles.
ASTRONOMY IN A WORLD AT WAR—DOUGLAS 159
more than two centuries, to receive its first modification. Nor was the personal
interest wanting: a great adventure in thought had at length come safe to shore.
[A. N. Whitehead.]
De Sitter’s expanding universe suggested an outward motion of
the stellar bodies within the framework of space as defined by his
modification of the Einstein equation of spacetime geometry. Ten
years later, Lemaitre, who had fought with the Belgian army in the
war years and afterward entered Louvain University, brought for-
ward his theory of expanding space. This made the radius of cur-
vature of space a function of time, and gave a new stimulus to the
astronomers in those great observatories equipped to probe most
deeply into space. In the following years, at Mount Wilson and
Harvard particularly, the exploration of space was carried on with
vigor, and methods were found of estimating the distances of the
remote galaxies. A special lens was designed to obtain their spectra
at Mount Wilson, and thanks to the broad, strong H and K lines of
ionized calcium, red shifts could be measured to distances estimated
as 250,000,000 light-years. The correlation between distance and red
shift has provided a remarkable confirmation of the theory of the
expanding universe. Recessional velocities up to one-seventh the
velocity of light have now been observed. In the years between the
wars a few voices were heard to question the interpretation of the red
shift as a Doppler displacement, but since no alternative explanation
suggested itself without postulating some entirely new law of Nature,
the expanding universe remained as a working hypothesis in the back-
ground of most astronomers’ minds.
One of the interesting things that these recent war years have
brought is the reopening of this question by E. P. Hubble. Is the
universe expanding? Is the red shift actually indicative of motion?
Or is the framework of the universe static? And if static, what is
the explanation of the displacement of all spectrum lines to the
red for distant galaxies? Hubble’s analysis of all available data
based on the assumption that the universe is expanding, necessitates
the calculation of a dimming factor due to recession. When cor-
rection is made for this in the estimation of distances, he claims
that a map results which is not of homogeneous density, which
implies an increasing rate of expansion with distance, and therefore
an “age” of the universe totally inadequate. On the other hand
when he assumes a static framework for the universe, the analysis
of all the data gives a map that shows a linear relation between
red shift and distance, and a homogeneity of density. This map
has more to commend it than has the former map, and hence the
assumption of a static framework appears to be favored. But, as
various astronomers have pointed out, the weakness of this result
lies in the large probable errors of the quantities involved, so that
160 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
even an apparent divergence of 30 percent from uniformity of den-
sity is not evidence weighty or certain enough to overthrow the
Lemaitre theory of an expanding universe.
IV
Important advances have been made recently by Gamow and
Bethe in our understanding of the sources of energy within stars
which permit them to radiate energy as they do. Bethe has given
an exposition of a cyclical sequence of atomic changes and interac-
tions whose net result leaves a star with fewer hydrogen atoms, but
with more helium and the liberation of excess nuclear energy in the
form of gammarays. This is now generally referred to as the carbon
cycle and it is too beautiful not to be recorded here, for though
published a few months before the war, it has been during the war
years that it has become a part of astronomical thinking. Of the
six stages, four result from collisions with hydrogen atoms in the
deep, hot interiors of main sequence stars, and two are spontaneous
disintegrations of unstable nuclei.

The two positrons rapidly interact with electrons to give rise to
gamma radiation. Thus is produced the penetrating radiation, most
of which in the course of its progress toward the boundary of the
star becomes transformed into the heat, light, and ultraviolet radiation
that pour out from the photosphere. The central temperatures of
the cool giant stars are insufficient to maintain this active cycle, but
theory can explain their radiant energy in terms of atomic collisions
and transmutations which are, however, noncyclical. Hydrogen,
deuterium, lithium, beryllium, boron are slowly transformed into
helium.
If the central regions of the hottest stars are not the crucibles of
nature wherein the elements are built up, where and under what
conditions were they formed? A highly speculative answer is to be
found in an intensely interesting piece of theoretical research carried
out during the early years of this war by Chandrasekhar and Heinrich.
They have been inquiring under what conditions of nature the basic
units of matter—electrons, protons, neutrons, positrons—could be ex-
pected to come together to form, in their various proportions, the
atoms of all the isotopes of the elements familiar to the chemist. As
ASTRONOMY IN A WORLD AT WAR—DOUGLAS 161
these elements compose all stellar bodies as well as all things ter-
restrial, their synthesis is a cosmic problem. They find that such
tremendous extremes of high temperature and high density would be
required that it is necessary to suppose that all the matter of the
known universe was once confined to a volume of radius only about
twenty times that of the solar system. Such a sphere drawn around
our sun as center does not now contain a single other star. Yet into
such a volume there may once have been packed not’ only all the
thousand million stars of our own galaxy, but all the millions of
other galaxies. This is indeed a picture reminiscent of the “giant
molecule” of Lemaitre. Since stars and galaxies are not now thus
packed, expansion must have taken place some time very long ago.
The present rate of expansion is such that galactic distances are
doubled every 1,800 million years. This gives the time elapsed, since
the expansion began, as several thousand million years which is in
satisfactory accord with the age of the earth as determined by other
physical lines of approach and regarded necessarily as a lower limit
for the age of the universe.
The last chapter on these cosmological problems is not yet written—
indeed there may well be many chapters yet to come and still no last
chapter in sight. It is the glory of the quest that as men seek the
unexplored horizon the margin fades forever and forever as they
move.
V
An investigation of very recent date has led to positive conclusions
about planetlike bodies associated with stars other than our sun.
There is strong evidence for this in the case of 61 Cygni and 70
Ophiuchi. This may be the beginning of a new search and a new
certainty in a field of astronomy hitherto theoretical and speculative.
Already several astronomers on two continents are studying the im-
plications.
Another astrophysical problem that has been worked upon with
considerable success during these war years, is the old backlog prob-
lem since 1869 of the solar corona. At Uppsala, Edlén has been
examining the X-ray and ultraviolet spectra of some very highly ion-
ized atoms, and a year ago his 1942 paper was received in England and
also in the United States of America. He uses his laboratory data as
basis for calculation of forbidden lines and altogether he identifies 17
coronal lines with lines of Fe X, XI, XIII, XIV, XV, Ni XII, XIII,
XV, XVI, Ca XII, XIII, A X; and two other lines less certainly with
Ca XV and A XIV. The ionization potentials required to produce
such atoms are very high, actually 233 volts for Fe X, 655 volts for
Ca XIII, and at first this seemed to offer an insuperable obstacle to
162 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
acceptance of Edlén’s proposals. The age-old question of Nicodemus
arose—how can these things be? These atoms are many thousand
miles from the photosphere of the sun; and to produce such ionization,
temperatures of 2,000,000 degrees are necessary. Speculation and
calculation have followed. A few months ago an explanation was
given in a letter to Nature by V. Vand of London. Even higher tem-
peratures he shows to be possible in the low-density regions of the
corona as a result of collisions of high-velocity atoms falling toward
the sun from interplanetary space. With the greater density of the
inner corona and consequent increase in radiation losses, he believes
conditions may be favorable to just those transitions postulated by
Edlén.

The numbers 136, 137, 256 will awaken in the minds of many of
you memories of a kindled interest, of perplexity, doubt, expecta-
tion, and perhaps of moments of great thrill, as you think back
over the last 15 years. One name alone stands central among these
memories—that of Sir A. S. Eddington. This has been his play-
ground pre-eminently. Some of us have stood fascinated at the edge
of the field watching this illusive game played patiently, skillfully,
brilliantly by one man, a master juggler with the elements of the
theory of groups, with quantum mechanics, and with the basic units
of measurement, producing, as from the proverbial hat, physical con-
stants both atomic and astronomical. Some there have been who
paused to watch briefly, to smile or even ridicule the Aristotelian
tour de force. But steadily and doggedly the theory has been pushed
forward, several papers having appeared in the last 3 years until
now the evidence is overwhelmingly great that, with no observational
data other than three basic constants, namely, the velocity of light
and the Rydberg and Faraday constants for hydrogen, it is possible
to calculate theoretically the following 13 physical constants: charge
e; Planck’s constant; masses of electron, proton, hydrogen atom;
gravitation constant; fine structure constant; nuclear range-constant ;
nuclear energy-constant; mass of universe; number of particles in
universe; Einstein radius of space; nebular speed. This is a striking
achievement.
Let us look briefly at just two of these constants. The recessional
velocity of the spiral nebulae is calculated to be 572.36 km. per sec-
ond per megaparsec. The observational value of Hubble and Huina-
son is 560. When the great 200-inch reflector comes into action, we
shall expect to see the observational value come closer to Eddington’s
determination.
The number of independent quadruple wave functions at any point
is 2X 186 X 2” or 3.15 X10” and in his earlier work Eddington iden-
:
ASTRONOMY IN A WORLD AT WAR—DOUGLAS 163
tified this with the number of particles in the universe. Since 1939 he
has found that a question of nonintegrability in spherical space
necessitates a reduction of 25 percent; so the number given in his
1942 paper is 2.36 X 10”.
This theortical approach has now reached a point where its author
can write “I think the theory now deserves to be the accepted theory—
my definition of an ‘accepted theory’ being that it is the theory which
is so far right that everyone is interested in trying to discover what
is wrong with it.” Can we wonder that he pauses in his work to refer
to “the devastating beauty of quantum arithmetic.” This entire in-
vestigation must surely rank as one of the great adventures of the
human mind exemplifying Blake’s stately metaphor—“Imagination
goes forth in its uncurbed glory.”

This brief survey of a few fields of astronomical research, incom-
plete as it obviously is, will serve nevertheless to indicate that pure
science is not dormant, much less is it dead, during the terrible years
when the vile demoniacal God of War stands astride the earth. For
many years the International Astronomical Union has been an in-
fluence for understanding, and for cooperation in the search for
knowledge with mutual respect and trust. It is temporarily in abey-
ance, but it will once again rise to carry on its good work. The
lesson of astronomy down the centuries has been one of international
interdependence and mutual indebtedness.
The problems facing mankind are very complex—the dealings of
man with man, the attitude of nation to nation. No solutions making
for international good will and world peace will be achieved by men
of narrow mind, myopic sight, and dwarfed soul. The far vision
in time and space, the winged imagination that leaps the barrier
of here and now—these are the qualities of mind and spirit needed in
every walk of life and needed superlatively in the leaders of every
nation if in the years just ahead of us progress is to be made toward
the great ideal of international unity. How can the eyes of the
blind be awakened to the dazzling vision of the City of God? For
some it may be by the contagious enthusiasm of a great teacher or
leader, for others the illumination from poetry, for some the spark
is kindled by the study of history, or of philosophy, and for yet others
it is through natural philosophy and astronomy. Mankind needs the
perspective of the cosmic background. “The great values,” said
Field Marshal Smuts, “retain their unfading glory and derive new
meaning from a cosmic setting.”
There is a challenge to the scientists and to the lovers of science
to teach the boys and girls, the young men and women of today and
164 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
tomorrow, the ideals, the aims, the methods, and the integrity of the
scientific approach to facts and to problems.
We do not forget the dictum of Rabelais, “Science without con-
science is damnation.” Wartime drives this home with bitter and
tragic intensity. But we may say with great assurance that science
with conscience has an essential part to play in procuring and main-
taining world conditions in which peace can endure.
All who have the ideal of world citizenship at heart, all who have
the far vision of things that have been and of things that may be,
and the realistic grasp of things that are, must cooperate in the great
task of bringing into the affairs of mankind upon this earth some
semblance of the order, beauty, and harmony of the universe of
stars. Toward this end, both directly and indirectly, astronomy and
astronomers can play a part; and it may prove to be a part which
no one else can play for them because they, the astronomers, are the
people with the fullest understanding of the cosmic background.
THE STRUCTURE OF THE UNIVERSE!
By CLAupE WILLIAM HEAPS
Professor of Physics, The Rice Institute
It may seem, at first sight, presumptuous to attempt the discussion,
in one hour or less, of such a comprehensive topic as the structure of
the universe. Actually the subject is not as big as it sounds. There
are, in one sense, as many universes as there are individuals; but the
universe in this personal sense will be ruled out of the present discus-
sion. A tremendous simplification is at once achieved when we limit
our topic to the physical universe. We now inquire, what is the phys-
ical universe?
Eddington has defined it as the “theme of a specified body of know]l-
edge, just as Mr. Pickwick might be defined as the hero of a specified
novel.” Such a definition emphasizes the epistemological point of
view and therefore it suffers from lack of definiteness and simplicity.
There is beautiful directness and decisiveness in the attitude of the
mathematician who wrote an equation on one line in one of his pub-
lished papers and said, “This equation contains everything we know
about the physical universe.” ‘The conciseness of the language of
mathematics is probably nowhere better exemplified than in this equa-
tion. On the other hand, the universe, if it can be described in terms
of mathematical symbols and with one equation, may not seem like
such a big subject after all.
To the physicist, matter, space, and time exist outside the human
mind. The physical universe is an objective, dynamic arrangement
of all matter, space, and time. In discussing the structure of the
universe we merely attempt to describe some of the features of this
arrangement.
Before beginning such a description it seems necessary to indicate
just how it is related to human welfare—since the general title of
this series of lectures is “Science and Human Welfare.” I am ventur-
ing to interpret the phrase “human welfare” in the broadest possible
sense. There are many types of scientific investigation which do not
appear to have any direct bearing on the pleasures or pains of the
1Public lecture delivered at The Rice Institute in the spring of 1948. Reprinted by
permission from The Rice Institute Pamphlet, vol. 30, No. 4, October 1943.
165
166 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
human race. The discovery of the planet Pluto cannot be said to have
done very much toward raising the sum total of human welfare, in
the ordinary sense. But in the broadest sense, it may be said that
the welfare of a nation is closely tied up with the capacity of that
nation for untiring search after truth. Intellectual unrest, intellectual
curiosity is, we like to think, essential to the true growth and develop-
ment of a people. A dairy company advertises that its milk comes
from contented cows. A rival company is perhaps more progressive
in its views when it advertises that its cows are not contented—they are
always trying to do better.
The thesis is, then, that the pursuit of pure knowledge is indicative
of a healthy national mind; that full development of intellectual
activity, whether it be in the matter of investigating the stars or in
building a better radio, is essential to the true welfare of a nation.
The Russians asked a captured Nazi why he came into their country.
He replied, “I am just a little man, I do what the Fiihrer says.” A
nation is facing tragedy when free speculation is discouraged, when
science is devoted solely to control of men and machines and to the
production of a workable mass of “little men.”
To begin this discussion of matter, space, and time we will try first
to systematize our ideas of space, or size, in relation to matter. Im-
agine a long, horizontal line drawn so as to represent the “the x-axis.”
Let all objects in the universe be placed along this line in the order of
their sizes. The smallest objects will be placed near the beginning of

the line, at its left end. Larger and larger objects will be placed
farther and farther to the right. We next divide the line into two
parts by a vertical line. All objects to the left of this vertical line
are too small to be seen with the naked eye, so this region is called the
microscopic region. In it are placed different kinds of particles such
as molecules, atoms, the proton, the neutron, the mesotron, the electron,
positron, and neutrino. These particles are placed nearer and nearer
to the origin of the line as they become smaller and smaller. It is
worth noting that nature seems not to have given us anything smaller
than the electron, in spite of the fact that there is plenty of room for
particles between the electron and the origin of the line.
To the right of the vertical dividing line we place all objects large
enough to be seen with the naked eye. This region is called the
macroscopic region. We might put in here, stones, mountain, earth,
STRUCTURE OF THE UNIVERSE—HEAPS 167
solar system, spiral nebulae. The farther end of the macroscopic
region may be given a special subtitle, the astronomical region.
We have arranged here various matter elements in a certain spatial
relationship. The time concept is involved because this is an arrange-
ment which may be correct only at one instant of time. It is possible
that the position of some of these entities on the line is constantly
changing. When an electron gets into rapid motion its mass is
changed a little and it shortens one of its dimensions. It thus shifts its
position on the line slightly to the left whenever it has a high velocity.
The solar system may be slowly running down so that the planets grad-
ually approach the sun. If this is the case the position of the solar
system on the line is slowly shifting to the left.
Certain segments of this line have occupied the attention of various
specialists. Astronomers deal with everything listed to the right of
earth. Thousands of specialists work on the section from earth to
atom. Physicists in recent years have concentrated intensively on the
segment from atom to zero. The discovery of the positron, the neutron,
and the mesotron within the last decade, has opened up a most fruitful
field of research in physics. In this region, forever beyond the reach
of the human eye, is probably contained most of the mystery of the
entire universe. As K. K. Darrow has expressed it, “This field is
unique in modern physics for the minuteness of the phenomena, the
delicacy of the observations, the adventurous excursions of the
observers, the subtlety of the analysis, and the grandeur of the
inferences.”
It is not too much to say that if some American physicist could only
make the right kind of discovery in this domain our entire oil and coal
industries would become more or less obsolete and World War II
would be won in a matter of days. It should also be said that such a
discovery is possible but not probable.
Returning now to our linear lay-out for the universe we may note
that everything to the right of proton is constructed out of the mate-
rial included in the range from proton to zero. All matter in the uni-
verse exists in the form of bunches or aggregates of smaller parts.
Protons, neutrons, electrons bunch to form atoms; atoms group into
molecules; molecules group into stones and mountains; stones and
mountains form the earth. In the astronomical field, planets group
about the sun to form the solar system—a solar system which in the
astronomical field is remarkably like the atom in the microscopic field.
The important unit of structure in the astronomical field is a sun.
Practically all the stars which we can see on a clear night are distant
suns, much like our own, although it is thought that only an extremely
small fraction of these suns have planets around them like our own.
61983045 —12
168 © ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
All these suns which can be recognized distinctly are grouped in a
sort of flattened, disklike bunch which is whirling in empty space.
Our own sun and planetary system is a member of this group, being
located about 30,000 light-years? distant from the center, or hub, of
this gigantic disk. When we look into space along the plane of the
disk the stars seem to be distributed very densely. We see the milky
way. This bunch of suns is called a spiral nebula. It is sometimes
called a galaxy, or an island universe. The word “universe” in this
sense has a restricted meaning because our island universe is not the
only one in existence. There are millions of others distributed
throughout space as far as our most powerful telescopes have been
able to penetrate.
The nebulae are by no means recent discoveries. Sir William
Herschel, 150 years ago, suspected that they were distant groups of
stars. The philosopher Kant believed that they were “systems of
many stars, whose distance presents them in such a narrow space
that the light which is individually imperceptible from each of them,
reaches us, on account of their immense multitude, in a uniform pale
glimmer.” They have been described as looking like “candlelight seen
through horn.” A rough diagram, not drawn to scale, is given in
figure 2 to indicate the total extent of the entire universe which has
been observed, up to the present, with our most powerful telescopes.
We might now indicate on the linear lay-out of figure 1 the approxi-
mate size of the largest bunch of matter, the spiral nebula, as 100,000
light-years. Also we might speculate as to the possibility of nebulae
themselves forming still larger groups. Extensive surveys have been
made by the astronomers at Harvard and Mount Wilson, of the dis-
tribution in space of the nebulae, and there is, indeed, evidence of
grouping of nebulae. It is legitimate to add another bunch of matter
to the line lay-out—the supernebula, or supergalaxy.
The supergalaxy is the largest known aggregation of matter in
the universe. Its diameter may be of the order of a million light-
years. At least that is the estimate made by Harlow Shapley of
the diameter of the group of nebulae in which our own is located.
Our local group contains perhaps 15 or 20 nebulae, but in some super-
galaxies there are hundreds of members.
So far, then, our picture of the universe reveals a granular, or
atomic structure. We start near the zero point of size, with a particle
of definite size. A fundamental law of attraction operates to cause
the small particles to group together to form larger particles, these
larger particles again group to form still larger particles, and so on
until we reach the limit of observation, the enormous supergalaxy.
2A light-year is the distance which light travels in one year. It is approximately
6,000,000,000,000 miles.
STRUCTURE OF THE UNIVERSE—HEAPS 169
We are unable to put a stop at the right-hand end of our line, as we
have done at the left end. Space may go on into infinity—possibly
matter may go on bunching up into larger and larger aggregates
with no limit as to the ultimate size of any final bunch, because there
may never be any final bunch. Speculations of this kind may be
interesting but they are not of much significance otherwise, because
they take us outside the realm of possible human experience.

It seems probable that in detecting the supergalaxy man has reached
the limits of observation in his probing of the depths of space. The
new 200-inch telescope will be doing a fine job in helping to chart and
analyze these enormous groups of matter.
The line diagram of the universe, limited at one end by the electron,
at the other by the supergalaxy, has given a rather simple picture in
terms of two variables, space and matter. The third variable, time,
must now be considered. We have to consider the relationship be-
tween the various units of our structure as this relationship may

change from time to time. Newton’s Law of Universal Gravitation
says that every particle of matter in the universe attracts every other
particle. If forces of attraction cause matter to bunch up into aggre-
gates of various sizes, why may not the various bunches themselves
start coming together until eventually there results just one large,
static bunch of matter floating quietly in an infinity of space? Such
an end result seems logical, but it cannot happen until the kinetic
energy of matter, the energy of motion, has been converted into
radiation and transferred to infinity. Such a transfer of energy
appears, in fact, to be going on.
A study of the motions of the various aggregates may be expected to
throw some light on this question. We start with the smallest par-
ticles, electrons, for example. In addition to random motions caused
by collisions with other particles, all electrons are supposed to spin.
They may be thought of as being like tops which never run down.
When an electron helps to form an atom, in addition to spinning
it also revolves about the nucleus, just as the earth revolves about
the sun. The aggregations of matter between atom and earth on
the diagram of figure 1 may have various kinds of motion but when
earth is reached we again have the spin about an axis and the revolu-
tion about the sun. Our sun, together with all the other suns in its
group, forms a nebula which spins with high speed about a central
axis. The spin velocity is very high, but the size of our nebula is
so great that it takes about 2 million centuries for it to make one
revolution. As Shapley puts it, this is the time required to “click off
one cosmic year.”
The motion of the supernebula is not known in accurate detail.
It is possible that some sort of gigantic spin is present here also, but
so far such a spin has not been detected. Instead, a very surprising
sort of motion has been discovered, a motion which is just contrary
to what we expect if matter is to agglomerate into one big bunch.
The supernebulae appear to be receding from us. The supernebula
to which our galaxy belongs maintains its fixed dimensions, and be-
haves more or less as a unit, but all the other supernebulae appear
to be flying away from ours with high speeds. The farther away
from us they are, the faster they seem to recede. There seems to be
no good way of explaining such a phenomenon. One might assume
that a primeval explosion started all matter out in all directions
from an original concentration, but there are serious difficulties
involved in such a theory.
The whole question of the expanding universe is definitely con-
troversial. The consequences of accepting or rejecting the theory
are so great that it will be worth while to review briefly the evidence.
STRUCTURE OF THE UNIVERSE—HEAPS lw |
Suppose the lights of a very distant city are observed at night
through a telescope. The various spots of light all look much alike.
However, they are not all the same in character. Some may be caused
by incandescent lamps, some by neon signs, some, perhaps, may be
due to the newer type of yellow sodium lamp used for illuminating
highways.
We now put a glass prism in front of the telescope objective. The
telescope must be deviated sideways, if we are to see the city through
the prism and the telescope. When we do see it, each spot of light
appears to be smeared out into a band of color. The colors present
in each spot of light are separated and spread out and we can see
just what colors are present in the light from each source. The neon
signs are characterized by definite colors in the orange and red; the
sodium lamps can be recognized by the fact that only one cae
yellow, is visible.
If we were to photograph the lights of an enormous city from an
enormous distance the whole city would appear as a small, luminous
spot. The prism would smear out the separate lights of which the
spot is composed, but they would all be superposed in a single
smeared spot for the whole city. However, if there were a large
number of sodium lamps one point in the smear would be brighter
than the rest because there would be an excess of the yellow sodium
light.
A nebula, consisting of millions of suns a long distance away, be-
haves like our hypothetical city except for one small difference.
Light from a sun has dark absorption lines or bands from which
color is missing as a result of absorption in the sun’s atmosphere.
There is a dark line in the spectrum of our own sun, corresponding
to absorption of hydrogen in the sun’s atmosphere. This dark line
always appears at the same place in the spectrum no matter what
kind of a source, and always means that hydrogen is present. Dark
lines appear in the nearer nebulae about where they should be in the
spectrum. For the more distant nebulae, however, they are shifted
toward the red end of the spectrum.
There is only one known explanation for such a shift of a spectral
line. If the source is moving away from an observer the light re-
ceived appears redder than when the source is stationary. This
phenomenon is called the Doppler effect. It is a matter of common
experience in the field of sound. The pitch of an automobile horn
is lowered as the horn passes rapidly by an observer and recedes
from him.
The photographs of the nebulae show that the hydrogen absorption
line is shifted farther and farther away from the normal position as
172 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
the pictures go to more and more distant nebulae. The amount of the
shift gives the velocity of recession. Many nebulae have been ob-
served and the conclusion is reached that for every million light-years’
distance from the earth the velocity of recession is increased by
about 100 miles per second. The farthest nebulae observed are flying
away from us with a speed of about 25,000 miles per second.
It is well to weigh critically the evidence for results like these. As
regards estimates of nebular distances, the methods used by astrono-
mers seem entirely adequate. In the nearest nebula individual stars
can be seen. Some of these stars fluctuate in brightness with a period
of 514 days. Similar stars, known as Cepheid variables, are found in
our own nebula, and the distances of a few of them have been deter-
mined by ordinary engineering methods. It is found that these stars
are all of about the same size, so that if one Cepheid variable is much
fainter than another its faintness may be attributed solely to its greater
distance. The distance of the nearest nebula can thus be determined
with considerable accuracy by comparing the brightness of one of its
Cepheid variables with the brightness of a similar star in our own
galaxy—a star whose distance has been measured by reliable methods.
Having a good estimate of the distance of one nebula it is legitimate to
infer that other nebula of the same type are fainter and smaller only
because they are farther away. It is thus possible to estimate their
distances. The results of these estimates might give occasional large
errors, but when a great number of observations are made the indi-
vidual errors must average out fairly well.
As regards the shift of the absorption line toward the red, a good
many attempts have been made to explain it in some other way than
by the Doppler effect. So far, all these attempts have failed or en-
countered logical difficulties. During the last few years, however,
certain evidence has accumulated which has brought about a para-
doxical situation in the theory of the expanding universe. There are
some very serious objections to the theory. First, let us suppose that
our explosion hypothesis is more or less in accord with the facts. After
all, if the nebulae are now observed to be scattering they must at some
previous time have been more closely bunched. It is not difficult to
calculate how long ago it was when the nebulae were all together and
touching each other. We know how far away they are now, we know
how fast they are receding, and how their velocity of recession varies
with the distance from us. These data enable us to calculate the time
when they must have started. According to Hubble, after all correc-
tions have been made this starting time was about 1,000 million years
ago. Unfortunately this is only a fraction of the age of the earth—
indeed there is evidence that life actually existed on earth that long
ago. It is difficult to see how our earth could exist in its present form
STRUCTURE OF THE UNIVERSE—HEAPS 173
at a time when all matter in the universe was assembled and ready for.
a cosmic blow-out of such tremendous proportions.
So much for objection number one. The second objection arises as
follows. When a source of light moves away from an observer there
are two effects produced. The first, the Doppler effect, has been
mentioned as a change of color, a reddening of the light. A second
effect is a decrease of brightness, known as the “dimming factor.” It
is easy to see why a light should appear to be dimmer when the source
moves away from the observer. Suppose a stationary machine gun
is firing bullets at a fixed target at the rate of five per second. Then
every second five bullets hit the target. However, if the gun is moving
away from the target, still firing five shots a second, there will not be
five bullets hitting every second. The bullet discharged from the gun
at the end of a given second will have had to traverse a greater distance
than the bullet which was fired at the beginning of the second, so it
will take a longer time to reach the target. Perhaps only four bullets
will hit the target in one second. The extra bullet has gone to fill the
extra space in the bullet stream—the extra space created by the reces-
sion of the gun. The case of a hight source is exactly analogous.
Now in estimating the distance of a nebula its brightness is taken as
a criterion of the distance. The question arises as to whether the dim-
ming factor should be applied when making the distance estimates.
If the nebulae are actually moving away from us then the factor must
certainly be applied. If the reddening of the light is not caused by
a velocity of recession then the dimming factor must not be applied.
With such tremendous speeds of recession this factor makes quite a
big difference in results.
The following discussion is very largely quoted from the annual
Sigma Xi lecture delivered in December 1941 at Dallas by E. P.
Hubble of the Mount Wilson Observatory. Dr. Hubble is one of the
world’s foremost authorities on the subject of nebulae.
Let us first suppose that the reddening of the light is not caused by a
velocity of recession. It may be due to some hitherto undiscovered and
unknown phenomenon. We can then estimate distances without any
dimming factor and a survey can be made to find out how the nebulae
are distributed throughout the region of space within our present
range of view. Such surveys have been made at Mount Wilson and
Mount Hamilton, out to a distance of 420 million light-years. Data
have also been obtained and analyzed at Harvard, and the net result
indicates a fairly uniform distribution of nebulae throughout the
observable regions of space. There are, on the average, just as many
per unit volume at great distances as in the immediate neighborhood
of our own group.
174 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
This result is intellectually very satisfactory. In fact, it agrees
with a fundamental principle of cosmological theory, a principle
which has been postulated by theorists for no other reason than its
appeal to our sense of order and the fitness of things. This principle
states that the universe, on a grand scale, will appear much the same
from whatever position in space it may be viewed or explored, This
principle of cosmology is satisfied, therefore, if the nebulae are not
assumed to be receding.
We next investigate the consequences of assuming the red shift to
be due to a real velocity of recession of the nebulae. The dimming
factor must now be applied in estimating distances, with the result
that the most distant cluster is actually about 13 percent fainter than
it would be if it were stationary. The scale of distances is thus
altered, so that when we make our space survey to find out how the
nebulae are distributed it turns out that they are no longer scattered
uniformly. The number per unit volume increases steadily with
their distance away from us. Here is a result which is intellectually
very disquieting. The cosmological principle of no favored position
is violated. We might be willing to accept this violation if it went
the other way, that is, if the density of nebulae decreased with dis-
tance. Then we would conclude, very happily, that we had discovered
another super-supergalaxy, another big matter bunch to put out on the
right-hand end of our linear lay-out. No such interpretation can be
given when the nebulae are found not to thin out at big distances, but
actually to become more dense in numbers.
It may seem obvious to the layman that we ought to discard the
idea of an expanding universe. It makes us worry about the short
time which has elapsed since the original cosmic explosion occurred ;
it bothers us with an increasing density of matter as we proceed far-
ther and farther into the depths of space; and the only evidence we
have to go on is a series of pictures, rather hazy, smeary pictures, in
fact, with a light patch shifted too far to one side.
The physicist and the astronomer, unfortunately, cannot treat these
fuzzy pictures in such a cavalier manner. There is no denying the
existence of the shifted light patch in the pictures, hazy though it
may be. There is no denying the fact that all such similar shifts of
color have been explained satisfactorily by the Doppler effect and by
the Doppler effect alone. One is reminded of the saying of the old
colored man, whose years of experience had developed a certain ripe
philosophy of life. “It ain’t so much what you don’t know that gets
you into trouble, it’s what you do know and ain’t so!”
There are several ways, more or less unsatisfactory, of escaping
from the dilemma of the expanding universe. The first way is not
STRUCTURE OF THE UNIVERSE—HEAPS 175
a good way, but like other escapist philosophies it must be consid-
ered and estimated for what it is worth. It involves spatial curvature.
The idea of curved space is now quite a familiar idea to most
people. Eddington, Jeans, Einstein, and others have written books
for popular consumption and the sales have been very gratifying.
Even the pulp magazines.do not hesitate to invoke the fourth dimen-
sion as a mode of escape for the hero or the villian. A simple way
of approaching the concept of spatial curvature is as follows. Think
of a straight line along one dimension. Given a second dimension
at right angles to the first, then we have the possibility of curving the
line into the second dimension. Think of a plane surface, like a sheet
of paper flat on a desk. Given a third dimension, at right angles
to the desk, we have the possibility of curving the paper sheet into
this third dimension. Think of a solid filling three dimensions. Give
a fourth dimension at right angles to the other three, we then have
a possibility of curving the solid into the fourth dimension. It is
only because we have three-dimensional minds that we cannot see
this fourth dimension.
A mathematician may speak of space itself as being curved without
reference to any solid matter in it. For example, consider the earth
to be perfectly smooth. If we were two-dimensional creatures instead
of being three-dimensional, we might draw a big circle on the earth’s
surface, measure its diameter and its circumference, and then find
that the circumference was not equal to z times the diameter. We
would not know that the circle was not flat (since we are assumed
to be two-dimensional), but we could certainly infer a curvature
of our flat space and even determine its radius if we knew enough
about ordinary Euclidean geometry, which would work pretty well
for small circles on the earth’s surface.
The mathematical description of the universe to which allusion
was made at the beginning of the lecture involved curving of three-
dimensional space in somewhat the same fashion as described above
for the two-dimensional space. If space actually is curved in this
way our ordinary solid geometry, Euclidean geometry, would not
be quite correct. In order to find out whether it is correct, measure-
ments of certain kinds must be made. For example, if a negative
parallax could ever be observed for a single star, a spherically curved
space would be implied. The mathematician Schwarzschild, a good
many years ago, attempted to find what curvature of space would
be possible according to certain types of non-Euclidean geometry.
In dealing with these geometries he said, “One there finds oneself,
if one but will, in a geometrical fairyland, but the beauty of this
fairy tale is that one does not know but that it may come true.”
176 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Schwarzschild’s results need not be considered here because his data
were limited and because we have at present more detailed modes of
procedure than he used. There are at least two mathematicians who
have achieved the unique distinction of having a universe named
after them. They are Einstein, and a Dutchman named de Sitter.
Both universes are non-Euclidean and the Einstein universe appears
to be the more popular. The curvature of the Einstein universe is
determined by the amount of matter in it, and if it is not a static
universe, by certain other factors. A chunk of matter produces quite
a large local curvature, which is evidenced to us by what we call
gravitational attraction.
This universe is not infinite in extent. It is a closed universe with
a finite volume but having no boundaries, just as the surface of a
sphere is a closed surface of finite area yet has no bounding edges.
In this universe one might expect to see a star in two directions, first
by looking directly at it, second, by looking in the exactly opposite
direction at light rays which have gone completely around the circuit
of the universe in the opposite direction. Star images have not been
seen in this way, possibly because their light is too faint after the
long trip around the universe. There is also the possibility that the
theory is wrong. It has, however, been seriously suggested that two
very faint nebulae, observed in a certain direction, may actually be
the backs of two of our nearest neighbors, as seen the long way
around.
The theory of a finite, closed universe is very attractive in many
respects. We may again use the term “intellectually satisfactory”
in this connection, largely because this universe can be given a concise
mathematical description and in terms that explain the gravitational
effects of matter. There is also, in many individuals, a. definite
repugnance to the idea of infinite space. In discussing the stars
Kant, in 1755, says, “There is here no end, but an abyss of real
immensity in presence of which all the capability of human concep-
tion sinks exhausted.” The finite mind likes to set up a blank wall
somewhere, in order to end it all. It is probably intellectually satis-
factory to know that one can start out in imagination and not have
to get farther away forever and ever, but will eventually get back to
the good, old, familiar region of the starting point.
With this picture of a finite, closed universe in mind we may now
return to the question regarding the nebulae. Why should they
appear to be crowded together at great distances from us? The
answer might be that the curvature of space appears to make them
crowd into smaller and smaller volumes as their distance increases.
If this is true it is possible to calculate what radius of curvature of
the universe would give the observed apparent crowding of the
STRUCTURE OF THE UNIVERSE—HEAPS 177
nebulae at great distances. Such calculations have been made and
the universe turns out to be remarkably small. In fact, it is so
small that our largest telescopes would allow us to see about one-sixth
of the way around it. This small universe is required in order to
explain the apparent nonuniform distribution of the nebulae. How-
ever, if we calculate the radius of the universe in this way we are
‘obliged to have only a certain amount of matter in it, since, according
to Einstein, the radius is determined by this total amount of matter.
Hubble has made surveys to find out whether the observed amount
of matter will fit in with the radius as determined above. He esti-
mates that if all observable stars and nebulae were smeared out
uniformly there would be a maximum of about one hydrogen atom
per cubic meter. This density of matter is far too small. In other
words, there is not enough matter in the universe to give it a curvature
great enough to spread out the nebulae uniformly. The theory of
curvature of space has, therefore, failed to resolve the problem.
Another way out of the dilemma is to suppose that the observa-
tions of the astronomers are in error. Here is what Hubble has to say.
These questions have been carefully reexamined during the past few years.
Various minor revisions have been made, but the end results remain substan-
tially unchanged. By the usual criteria of probable errors the data seem to be
sufficiently consistent for their purpose. Nevertheless, the operations are deli-
eate, and the most significant data are found near the limits of the greatest
telescopes. Under such conditions it is always possible that results may be
affected by hidden systematie errors. Although no suggestion of such errors
has been found, the possibility will persist until investigations can be repeated
with improved techniques and more powerful telescopes. Ultimately the prob-
lem should be settled beyond question by the 200-inch reflector destined for
Palomar.
This telescope will have about twice the range of the best one now
in use. Work on it has been stopped by the war, so it is impossible
to predict just how soon it can be put to work on this problem.
The last way which may be suggested for escaping from the
dilemma is to suppose that in the region of astronomical magnitudes
some new principle of nature is operative—some principle which we
have not yet discovered in the ordinary macroscopic field. Such a
principle would have to free us from the necessity of using the Dopp-
ler effect, and we would no longer have to say that experimental
observation shows the universe to be expanding. This new principle
would, therefore, have to explain why the light from nebulae gets
redder and redder as it travels greater and greater distances, Per-
haps light which has been traveling for 100 million years in a straight
line exhibits its senility by a decrease in the frequency of its vibra-
tions. We do not know of any possible reason such as this why old
light should be different in any way from new light. The only place
178 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
from which we can get really old light is from the distant nebulae,
so our chances of establishing by experiment a new principle of
physics like this seems at present to be involved in a vicious circle
from which there is no escape.
It appears, therefore, that our knowledge of the structure of the
universe at the limits of the astronomical range is unsatisfactory.
We have to recognize that there are discrepancies between theory and
experimental observations. Hubble says that “a choice is presented,
as once before in the days of Copernicus, between a strangely small,
finite universe, and a sensibly infinite universe plus a new principle
of nature.”
We may now go back once more for a comprehensive view of what
we have called the linear lay-out of the universe in figure 1. The
three components, or variables, were assumed quite simply to be space,
matter, and time. At the right-hand end of the scale we have become
embroiled in some rather questionable speculations regarding the
nature of space and the behavior of light. In this region, where a
light-year is the unit of distance and a nebula the unit of mass, we
have good reason for suspecting that the mechanics of the universe
cannot be described or explained in such a simple way as in the region
of miles and mountains.
Peculiarly enough, if we go from the enormously great region to
the extremely small region, the region of the electron and the posi-
tron, we encounter similar difficulties. You will remember that Dar-
row characterized the microscopic region as unique because “of the
adventurous excursions of the observers,” and “the grandeur of the
inferences.” One or two of these inferences and excursions may be
cited here, and it will appear that the simple concepts of space and
matter have suffered in the microscopic field in much the same way
that they have suffered in the astronomical field. As the result of
investigations in the field of the small particles it has become neces-
sary to broaden our ideas as to the nature of matter. Cloud-chamber
pictures have allowed us practically to see two particles of matter
created in space from the energy contained in radiation.
The thing that happens is that a photon, an atom of radiant
energy traveling with the speed of light, somehow gets itself into a
peculiar situation in a microscopic field of:some kind. The result
is that the photon changes into two particles with electric charges,
a positron and an electron.
In the macroscopic size range an equivalent phenomenon would be
for a quantity of sunshine, passing by an iron ball, to change sud-
denly into a couple of buckshot.
Needless to say, no one has ever seen anything like this happen. It
is only when sizes become so small as to prevent direct observation
STRUCTURE OF THE UNIVERSE—HEAPS 179
that the event occurs. We may well say that something peculiar is
going on in the microscopic field. Something is happening which is
foreign to our ordinary experience.
Technically this phenomenon is known as pair production by a
photon. The reverse process, conversion of matter into radiation,
can occur when an electron and a positron come together under proper
conditions. They disappear and two photons of radiation are shot
out with the speed of light in opposite directions.
Matter and energy can now be thought of as practically synony-
mous. It thus becomes possible to make certain grand inferences
with the object of saving the universe from running down. Millions
of suns are slowly but surely converting their matter and their
energy into radiation and this radiation is constantly escaping into
infinity. Perhaps somewhere in space radiation may be changed back
into matter. Perhaps the universe is engaged in a reversible cycle,
instead of an irreversible one, as is commonly supposed.
As an illustration of what Darrow calls an “adventurous excursion”
of an observer we may take the Dirac theory of the positron. Dirac
is a brilliant young Englishman, a mathematician who has demon-
strated a high degree of daring and originality in his handling of
theoretical physics.
His theory of the positron starts out with two peculiar assumptions.
First, a particle may have a negative kinetic energy. Second, all
space is filled with particles of negative kinetic energy. There is a
distribution of electrons of infinite density everywhere in the world.
A perfect vacuum is a region where all the states of positive energy
are unoccupied and all those of negative energy are occupied.
When an electron, by some means or other, gets knocked out of
this state of negative energy into a state of positive energy, it is
observed as an ordinary electron; the hole which was left is a
positron. This hole may wander around for a short time, but there
are so many more electrons in the universe than holes that it is not
long before some electron drops into the hole and both hole and
electron disappear from the view of normal people. The very short
life of the positron is thus explained, as is also the phenomenon of
pair production and the conversion of matter into radiation.
I have given this hasty outline of the theory, not that I expect
anyone to understand it—it is hardly to be expected that negative
energy can be understood—but because it illustrates the lengths to
which a theorist has to go in creating physical explanation in this
field. In the microscopic range of sizes a quite perfect explanation
of things is given by a specialized type of mathematics called wave
mechanics. It is only when this mathematical symbolism is explained
in terms of physical symbolism that we call it an adventurous
180 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
excursion. Dirac showed great courage in even trying to give a
physical picture of his mathematical theory. The fact is that in
the microscopie field things may behave in a way entirely foreign to
the way in which we have always seen large objects behave, hence they
cannot be explained in the old familiar ways.
There is in most people a strong tendency to label as “bunk” that
which is not understood. This tendency is, on the whole, a healthy
one. Skepticism is preferable to credulity if one is thinking in terms
of the struggle for existence. The radio listeners who believe all the
remarkable statements made about cough syrups, breakfast foods,
cigarettes, etc., must certainly be struggling very hard for existence.
However, skepticism based upon a lack of understanding is a danger-
ous attitude of mind. Prof. P. W. Bridgman of Harvard has this to
say in his book, “The Logic of Modern Physics”:
It is difficult to conceive anything more scientifically bigoted than to postulate
that all possible experience conforms to the same type as that with which we
are already familiar, and therefore to demand that explanations use only elements
familiar in everyday experience. Such an attitude bespeaks an unimaginative-
ness, a mental obtuseness and obstinacy which might be expected to have
exhausted their pragmatic justification at a lower plane of mental activity.
The explanation of microscopic phenomena, then, utilizes concepts
which are not familiar to everyday experience. For that reason the
microscopic tends to undermine any smug complacency we may have
regarding our knowledge of nature and the universe. Take, for
example, the Heisenberg uncertainty principle. This principle states
that we can never know accurately both the position and the velocity
of asmall particle. It is easy to see why this is true. We can see the
small particle because light has bounced off of it into our eye. We see
it in the direction from which the light bounced.
But the light, in bouncing from the particle, must have given it a
push so that either its position or its velocity will have been changed
by the mere fact that light must be used to observe it. By the time the
light photon gets to the eye of the observer the particle will not be at
exactly the spot from which the photon appeared to bounce.
This uncertainty principle has been given an exact mathematical
formulation. It turns out that if the position of an electron is known
to within 0.004 inch then the speed of its motion is uncertain to within
about 3 feet per second—the speed of a slow walk.
The tendency, at first, is to consider this as rather a superficial
principle. I can easily imagine a particle to have both position and
momentum simultaneously; why bother so much about a mechanism
for determining them? “However, a thorough study of the situation,
with an analysis of every conceivable means afforded by nature for
making determinations, impresses one with a feeling that here is a
STRUCTURE OF THE UNIVERSE—HEAPS 181
conspiracy of nature to prevent man from acquiring too much detailed
information. A conspiracy of nature is a law of nature; we cannot
pass it over as being of no importance. It is as if nature had erected
a wall of impenetrability around the smallest particles and forced us
to see them only partially, as if through the cracks in the wall.
It appears, therefore, that we are asking a meaningless question
when we ask just where an electron is when it has a certain definite
momentum. No possible operation can be thought of by which an
answer to this question can be obtained without violating a law of
nature. The conclusion is that the electron cannot have an exact
velocity and an exact momentum simultaneously. There is an essen-
tial fuzziness in the very foundations of nature herself. Time and
space are a little peculiar in the microscopic region, most certainly.
Someone has said that “the infinite, whether the infinitely large,
or the infinitely small, seems to carry disaster in its wake.” I do
not think the word disaster is happily chosen in this connection.
It is true that the two infinities at either end of our linear lay-out
have shattered the beautiful, crystal-clear mechanical system which
described the universe during most of the nineteenth century—when
the luminiferous ether was as definitely material as a piece of iron,
and when a scientist could say that practically all pioneer research
in physics was over and nothing remained except to measure things
with increasing accuracy. This complacent attitude is fortunately
gone forever, and the two infinities have had a great deal to do with
its disappearance. The new problems presented, the paradoxes, the
uncertainties, all combine to give us a picture of modern science
once more struggling, once more growing. It seems better to change
the quotation to read, “The infinite, whether the infinitely large or
the infinitely small, seems to have carried renaissance in its wake.”
In summing up the subject we may say that the small part of the
universe, open to everyday experience, has given us a simple concep-
tion of nature, a simple body of laws, which seems unable to cope
with problems either in the region of the supernebulae or in the
region of the extremely small particles.
In the latter field we have found that, properly speaking, descrip-
tions of phenomena must be mainly mathematical. Such descrip-
tions are quite adequate at present, and we feel that the main prob-
lems of explanation are well in hand. But we must be careful not
to expect the same type of explanation that is used for objects of
ordinary size, and we must remember that here there is a certain
indefiniteness of behavior. We do not say that a small particle can
never get over a high hill when it does not have enough energy to
carry it tothe top. We say that the probability of its getting over is
182 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
small. It actually has a small probability of doing the job with an
insufficient amount of energy !
In the region of the supernebulae we are at present up against a
paradox. We are at liberty to suppose that space is of a peculiarly
curved character, or that it goes on to infinity; that the supernebulae
are flying away with enormous velocities, or that some unknown
principle of nature is deceiving us. We may be affected by a feeling
of futility because of this state of affairs, and even have a sympathetic
feeling for St. Ambrose, who in A. D. 389 wrote:
To discuss the nature of the earth does not help us in our hope of the life to
come. It is enough to know that, Scripture states that He hung up the earth
on nothing. Why argue whether He hung it up in air or on water? The
majesty of God constrains it by the law of His will.
The spirit of modern science is not in agreement with St. Ambrose,
and is not to be discouraged by apparent contradictions. This spirit
demands continual arguing and speculating as to how the universe is
hung up. Certainly we will always see as through a glass darkly,
but just as certainly we will always keep on trying to polish the
glass.
INDUSTRIAL SCIENCE LOOKS AHEAD:
By BRIGADIER GENERAL DAvID SARNOFF
President, Radio Corporation of America
Industrial science at war is shaping a new world. While the bat-
tle lines of the United Nations encircle the Fortress Europe and the
gigantic pincers of victory tighten on the enemy in the Pacific, civi-
lization advances ever closer to the postwar horizon. With victory
will come the day when the scientific instruments and processes of
war will turn abruptly to peace. Machines and tools, as well as
industrial and economic thinking, will be converted quickly from the
demands of war to the needs of peace. Industry will be called upon
to relieve the strains of war with utmost speed by ministering anew
to human welfare, health, and comfort. Postwar planners are now
at work in many fields of industrial endeavor.
It is not new for American industry to be surveying and planning
for the future. That process is always at work here, whether the
world is at peace or at war. Only by advanced thinking, research,
engineering, and continual pioneering, can industrial science put
new ideas into action. By doing this, industry serves its workers
and the people, and thereby wins the right to survive.
We have but to consider some of the outstanding wartime develop-
ments of industrial science to realize their widespread applications
in all fields, from automobiles to giant turbines and diesel engines,
from cameras to facsimile and television. Endlessly these advances
extend into every realm of our daily lives. Among the promises of
better living we are told of new plastics, light metals, synthetic tex-
tiles, high-octane gasoline, artificial rubber, luminescent lighting, air-
conditioning, dehydration of foodstuffs, and many other innovations.
We even hear of glass flatirons and plastic lenses. We are promised
revolutionary changes in homes, aircraft, communications, ships,
railroads, automobiles, highways, clothing, and foods. In myriad
ways the wartime inventions in electricity, metallurgy, chemistry, and
physics will open new gateways for industrial science to enter and
enrich our everyday life.

184 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
As for the great, modern art of radio, I can promise you that as
a service to mankind everywhere it will keep pace with the march of
science and industry in every other field.
Today is the anniversary of a historic event that provides us with
a timely opportunity to review the remarkable advances of radio
within a quarter century, to reflect upon its vital role in the war, aad
to look into its future.
Twenty-five years ago this morning, news flashed across the hemi-
spheres that the first World War had ended. In retrospect that day
appears as a fleeting moment. History lifted her pen and paused to
dot the “i” of an empty victory that proved to be only the prelude
to a global war unprecedented in fury, extent, and destruction.
In that autumn of 1918, Germany’s pleas for peace had revealed the
plight of the German people. Germany was cracking. American
radio was entrusted to transmit to a defeated nation President
Wilson’s Fourteen Points as a basis for the restoration of peace, and
for a general armistice on land, on water, and in the air. Radio opera-
tors stood by for the answer. It came on the midnight air of November
11, when silence in the “ether” over the Atlantic was interrupted by a
flash from Europe. At 2:45 a.m. New York time, the news broke.
The State Department in Washington announced the Armistice had
been signed at midnight, and hostilities would cease at 6 o’clock in the
morning—11 a. m. in France.
There was no radio broadcasting to spread the welcome word—“It’s
over, over there!”
Under the banner headline “Peace,” Americans read the news at
their breakfast tables. The world was only a reading world at that
time. It had not yet learned to listen. News spread slowly in 1918.
Although powerful radio alternators relayed these tidings around
the world to ships on the Seven Seas, homes were not yet radio
equipped. Many days passed before news of the Armistice filtered
into remote hamlets and farms. War correspondents were scribes,
not eyewitness broadcasters; they had the pen but no microphone.
Today news travels at the speed of light, in every language to every
corner of the earth.
In those days there were no globe-encircling short waves, no high-
power vacuum tubes, no universal receiving sets. The radiophone
was just learning to talk. The electron tube had not yet revealed
its power and its unlimited possibilities.
The radio of that day gave everything it had to win the war. Re-
search men and engineers rushed new devices into service to main-
tain contacts with the battle fleet, with the convoys and the American
Expeditionary Force in France. Although ships in the mid-Atlantic
could not maintain direct contact with American and European shores,
INDUSTRIAL SCIENCE—SARNOFF 185
the long waves of powerful land stations swept across the sea and
linked America with its Allies. War bulletins moved through the air
at the rate of 30 to 40 words a minute. Today, short waves and high-
speed automatic machines handle news at the rate of more than 600
words a minute. In the First World War, American newspapers had
to wait for ships to arrive with the historic pictures of Pershing and
the A. E. F. in France. Now radiophoto service can deliver pictures
of Eisenhower and his forces in Italy and MacArthur and his troops
in the South Pacific a few minutes after the camera snaps them.
Today, largely because of radio, New York is the communication
center of the world. In 1918, it was London. During the first World
War the United States found itself at the mercy of foreign communi-
cations. America learned the lesson then, that radio was the nerve
system of war as well as of peace. Immediate steps were taken to
safeguard the future, to give the United States supremacy in world-
wide communications and to make sure that never again would this Re-
public be dependent upon the wave lengths, cables, or wires operated
and controlled by other nations.
As a result of this determination, the direct radiotelegraph circuits
of RCA now reach 51 countries in Central and South America, the
West Indies, Europe, Asia, Africa, and Australasia. Radiophoto cir-
cuits operate between New York and London, Stockholm, Berne, Mos-
cow, Cairo, and Buenos Aires, while the terminal at San Francisco
serves Honolulu and Melbourne.
In this war, radio is everywhere—with soldier, sailor, marine,
and airman. Modern warfare has put radio instruments into every
bomber and fighter plane, into every mechanized unit, and into every
ship. There were no walkie-talkies or handy-talkies in No-Man’s
Land, at Verdun or at the Marne. The “cease firing” order signed
by Foch was shouted and carried by runners along the trenches. The
radio equipment of that day was too massive and too heavy for more
than a limited use in airplanes. Now compact, efficient radio goes
aloft with all planes; wave lengths are their life lints. Coordinating
great aerial squadrons, radio guides the bombers and swarms of
fighters over the targets, and safely back to the airports. The para-
trooper leaps from the skies with a miniature radio transmitter—no
larger than a cracker box—strapped to his belt. The artillery,
through its radio, knows at all times what the infantry wants, when
it wants it, and exactly where it wants it.
These historic comparisons dramatize the great advances made by
radio in a quarter of a century. Industrial science and private enter-
prise, free and unfettered, took the war-born electron tubes, the radio-
telephone, and the short waves, and adapted them to peaceful
pursuits. Clues to what might be accomplished in peace were, how-
186 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
ever, in the air during those final months of the first World War.
When a sub-chaser dashed out to sea from a port in Maine, its radio
operator moved a portable phonograph near to his radiophone micro-
phone to broadcast a popular wartime tune, “I May Be Gone for a
Long, Long Time.” From the Navy station at New Brunswick, N. J.,
the “Star Spangled Banner” was broadcast up and down the coast.
These were forerunners of the day when radio music from hundreds
of stations would encircle the globe.
War had revealed that new instruments could be made available
for mass communication. The time was opportune and industrial
science was prepared to answer the challenge. Soon after the Ar-
mistice, America became aflame with a new national pastime—that of
listening-in. The vast industry of broadcasting came into being. Its
achievements as a service to America and to all the world during the
past quarter of a century are an epoch-making and dramatic story
of American ingenuity and enterprise at its best.
In no other nation has radio developed as it has in the United
States. Nowhere else are people better informed. Today this
country is served by more than 900 broadcasting stations and 4 na-
tional networks. There are 60,000,000 receiving sets in our land.
The owner of every set is free to listen to any wave length from any
country. American radio dials are symbols of freedom.
The scientists, who worked out inventions and harnessed the wave
lengths to equip America with this unsurpassed radio system, realized
only vaguely that their achievements might be used in a second World
War. Theirs were the tasks of peace. They worked to make a sym-
phony orchestra sound with perfection hundreds and thousands of
miles distant from its source and enable the human voice to ring true
on the other side of the globe.
They extended the influence of news, education, and religion to all
parts of the earth. They made the world an open-air theater in
which countless millions of people could enjoy free entertainment.
Thus, scientists made American radio the Voice of Freedom, so
interwoven with our daily lives that we have come to think of radio
as an achievement only of the twentieth century. It is, however, a
child of the ages. Modern radio came into existence through a long
process of evolution. The long corridors of time through which man
has conducted research and experiments extend far into the past.
They lead back to ancient Greece. There the first electric sparks,
called electrum, kindled a new science and unleashed a new force—
electricity.
While the men of science were seeking to explain the mystery of
these sparks, the philosophers of Greece forsaw that if democratic
government were to remain effective, the range of the human voice
———
INDUSTRIAL SCIENCE—SARNOFF 187
would have to be greatly extended. Aristotle argued that the best
of states might well outgrow geographical boundaries with popula-
tions reaching such size that well-ordered and efficient government
could not function. He said that a democratic government required
that the citizens keep in touch with one another; that their leaders
know each other and that they study at first hand their common poli-
tical problems and the policies necessary to meet them. But Aristotle
warned that it would be impossible to accomplish this in the overgrown
state, “for who could be the leader of the people in such a State, or
who the town-crier, unless he have the voice of a Stentor?” It
would seem that Aristotle even forecast the need for television, be-
cause he believed that the people needed to see their leaders, as well
as hear them at long range.
Two thousand years later we have seen this come to pass, for science
has provided government and its leaders with radio. The entire Na-
tion has become an open forum. The leader of the modern state is
heard at one time by more people than Aristotle and Socrates reached
in their life time. Electricity has made the microphone the voice of
the Stentor; our leaders talk to the people, and at the same instant
they are heard around the world.
We of this generation have seen men of evil intent stopped by the
very tools of science they perverted ruthlessly to extend their power.
We have watched science halt the tyrant and dictator as the stentorian
voice of the United Nations cried out in defense of freedom, democracy,
and justice.
When this war ends, we shall be on the threshold of a new era
in radio—an era in which man will see, as well as hear, distant events.
The first two decades of the century belonged to wireless telegraphy.
The second two decades featured sound broadcasting; the third two
decades promise television. It is not too bold to predict that the fourth
two decades will introduce international television with pictures in
color.
It is even possible that in the two final decades, we may complete
the century with power transmission by radio, and its use in the
operation of vehicles, automobiles, ships, railroads, and airplanes.
When completed, the story of these first hundred years of radio will
make fascinating reading. Even a Jules Verne could not tell us all
that lies ahead in this magic realm of radio-electronics.
The science of radio is no longer confined to communications.
Among revolutionary accomplishments in other lines, we have the
electron microscope, one of the most important new scientific tools of
the twentieth century. Developed in RCA Laboratories, and based
upon television techniques, this instrument has a high wartime prior-
ity rating for use in scientific, medical, and industrial research. For
188 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
the first time it has made it possible for us to see and identify mole-
cules, and to photograph the influenza virus. It has revealed, in in-
finite detail, the true structures of fibers, crystals, and pigments. The
submicroscopic world is now opened wide for exploration. Bacteria,
tissues, and minute particles of matter have been brought within
range of man’s eye, for the electron microscope, many times more
powerful than the strongest optical microscope, permits magnifica-
tions up to 100,000 diameters. A needle on such a scale of magnifica-
tion would appear as huge as the Washington Monument; a blood cor-
puscle as large as the wheel of an automobile and a football field
five times the size of the United States.
Wartime industrial research and engineering have rushed into use
still another branch of radio—the art of utilizing high-frequency
radio waves for heating. It violates no military secret to report that
in this new field of radiothermics, a laminated airplane propeller can
be processed in minutes compared with hours required by ordinary
heat and pressure methods. In many cases where uniform heat under
accurate control is necessary in industrial processes, radiothermics
offers great promise in efficiency and time saving. The wide scope
of its application ranges from case-hardening steel to dehydrating
foods, from gluing prefabricated houses to seaming thermoplastic
materials by means of a “radio sewing machine.” ‘These accomplish-
ments are all based upon the simple fact that microwaves, in penetrat-
ing an object, encounter resistance and create heat.
Farther afield from communications, research men are exploring
supersonic vibrations, far above the range of the human ear. The use
of these ultrasonics in chemistry may open a field in which high-
intensity sound accelerates chemical reactions. Experiments also
indicate important possibilities in many other fields including under-
water communication, emulsification of liquids, and precipitation of
dust from the air.
We attribute all these lines of progress to the science of electronics.
The heart of that science is the radio tube. Millions and millions of
radio-electron tubes are on duty around the world. They are being
manufactured in the United States at the rate of 400,000 a day. The
communities in which they are made are on the front line of pro-
duction. The great importance of each radio tube that moves off the
production lines can only be envisaged by considering the many func-
tions it performs in helping to win the war. The delicate finger of
the worker who makes the tubes has a task as vital as the finger of a
soldier on the trigger of a rifle.
Likewise, radio-electron tubes are as important in peace as in war.
They are the master keys to revolutionary advances in radio. They
have registered the sound of footprints in the past; they are the
INDUSTRIAL SCIENCE—SARNOFF 189
pulse of the present and the “eye” of television that sees far into the
future.
The day may come when every person will have his own little radio
station tucked away in his pocket, to hear and to communicate with
his home or his office as he walks or rides along the street.
We have much to learn about the microwaves, in which is wrapped
up this new world of individualized radio. Tiny electron tubes may
make it possible to design radio receivers and transmitters no larger
than a fountain pen, a cigarette case, a billfold, or a lady’s powder
box. Some day people may carry television screens on their wrists
as they now carry watches. As the useful spectrum of radio ap-
proaches the frontiers of light, the apparatus will become simpler
and more compact.
Today science is leading us out of a world in which radio has been
blind. Tomorrow we shall have radio sight. By this I do not mean
that we shall look only at pictures in motion that travel through the
air. Radiovision will have many uses. It will serve wherever sight
isneeded. For instance, it will be used to prevent collisions on high-
ways and railroads, on sea lanes and on the airways of the world.
Radio will be the new eye of transportation and commerce. Appli-
cations of radio optics are unlimited. With radio ear and eye to
guide them, the great stratoliners will be superhuman in their in-
stincts of hearing and seeing as they speed through space with
passengers and freight. Radio, which made the world a whispering
gallery, will turn it into a world of mirrors.
Radio’s great responsibilties do not stop there. A formidable task
lies ahead for communications in the restoration of peace, in the re-
construction of the world, in the reestablishment of international
trade.
If American industrial science is to play its destined role in the re-
construction period, government should not unduly restrict private
enterprise or enter into competition with industry. On the other
hand, it is of no avail for industry merely to point to the dangers of
governmental restraints. Industry must give evidence of leadership
by presenting practical alternatives.
The day of pioneering in America has not ended. Trail blazing
now calls for joint effort by government, labor, and industry. Their
authority, experience, and vision must fuse harmoniously to achieve
success. The same spirit of give-and-take must prevail in industrial
statesmanship as in national and international statesmanship. There
must be but one goal—the welfare of the people and the Nation.
Industrial statesmanship can accomplish more than political states-
manship in solving the postwar problems of employment, mass pro-
duction, prosperity, and the continued uplift of the American standard
190 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
of living. Industry can be the great motive power in the solution of
these problems. The future of every American home and family
depends upon it. Therefore, it is imperative that after victory is
achieved on the battlefields, American industry devote the same all-
out efforts to the peace that it devoted to the war. There can be no
let-down. The problems of peace will be of great magnitude. After
the devastation of war, mankind will be called upon to win the peace
and to make that peace secure with happiness for all people. If in-
dustrial statesmanship fails in this great opportunity, then the ap-
proach to the postwar problems necessarily will be political instead
of economic.
America’s cultivation of science has proved the Nation’s salvation
in modern warfare. It must not be otherwise in peace. Pioneering
and research create wealth and employment.
In considering opportunities for employment after the war we must
lift our sights to the skies. Man, long confined in his activities to
the surface of the earth and beneath the ground, now finds that the
air is a new dimension, offering new adventures and pioneering by
a new generation. The air is a universal chemical and physical lab-
oratory in which essential elements for life on earth are created.
Nature herself makes unlimited use of celestial space for trans-
mission of light and heat from the sun. Only in recent years has
man learned to use the air. Only now is he beginning to discover
its tremendous potentialities. Literally out of thin air, chemists are
creating new products, physicists are building new services, while
man is talking on unseen waves and flying on invisible beams.
On the surface of the earth, ships and railroads, automobiles and
industrial machines have created millions of jobs. Underground
coal, oil, and minerals provide employment for other millions. Above
the earth aviation and radio, electronics and television can open the
way for new opportunities in re-employment of war workers and for
the millions of men and women who will return from service.
It is estimated that 10,000,000 jobs which did not exist in 1940 must
be found to solve the postwar problem of employment. One great
hope in helping to meet this unprecedented challenge will be found in
the fertile and unexplored frontiers of space. Science, offering new
incentives, is beckoning capital to venture into the open skies. We
are challenged to look upward to our future.
Horace Greeley, if here today, might say, “Go up, young man, go
up and grow up in space.” There, lies the unfathomed “West” of this
century, with no last frontier; there, lies a vast wilderness rich in
resources, opportunities, and adventure. The “Forty-niners” of the
present decade will be prospectors in research. They will travel
through the air to stake their claims to fame, fortune, and freedom.
INDUSTRIAL SCIENCE—SARNOFF 191
To assure the full attainment of these results, private industry and
the Government must play their parts with the utmost honesty of
purpose, encouraging individual and collective initiative. The na-
tional growth of the United States and its contributions through
research and invention, are historic proof that traditional American
cooperation between industry and government promotes the best
public interest.
The role of government in its relationship to labor and industry
should be that of an umpire. A wise government does not seek to
favor either management or labor. It must be impartial, not partisan.
When the war ends, and we enter the immediate period of transi-
tion, the Government in fairness to both labor and industry must
readjust its rigid wartime controls. The emergency regulations nec-
essary in wartime, but not necessary in peacetime, should be reduced
as speedily as practicable. Elimination of wartime restrictions will
enable manufacturers to produce and supply the goods needed by the
Nation, to maintain employment, and to adapt new developments in
industrial science for the benefit of all people.
America must be practical. Science and industry must have
American independence if they are to succeed in the gigantic task of
reconversion, re-employment, and world rehabilitation.
Never again can the United States be isolated and secure within
its own shores. In the fact that no spot on the globe is farther than
60 hours’ flying time from any local airport, is seen the truth that
nations must live together as good neighbors. Shriveled by radio
and aviation, the new world is a single neighborhood. That is not a
theoretical concept. It is a fact.
Today man can travel by train from Chicago to New York in 17
hours; he can fly in 5 hours. He saves 12 hours, but it is of no avail
if he does not use that time constructively. If people achieve more
leisure, what are they to do with the newly found hours of freedom ?
This is one of the paramount problems that faces the postwar world.
Recreation and entertainment are vital to a happy life. But to be
content man must also work. Mere idleness does not produce hap-
piness or progress. Life is measured by time; it is too fleeting and
precious to waste.
Entertainment can be as refreshing as sleep. The brain to gain
new ideas and to think clearly also must have diversion. In leisure
some of the greatest dreams of all time have been born and have
grown into revolutionary ideas and inventions. The complete con-
ception of the telegraph flashed into the mind of Morse while on an
ocean voyage. The idea of wireless flashed into Marconi’s mind
while vacationing in the Alps. Great ideas in science, art, and litera-
ture seldom come directly to the workbench; they are released at
192 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
unsuspecting moments when the subconscious mind has opportunity
to come into its own.
In broadcasting we have an outstanding example of an art that is
measured by time and linked with opportunity. The listener may
use the hours to good advantage, or he may waste them. It is the
use to which he puts his radio set and his freedom in selection of pro-
grams that reveals the inherent value of broadcasting. The program
is the essence. If it brings laughter, if it stimulates thinking, or rests
the tired mind, or keeps the listener informed and in touch with
his fellowmen, then radio is an antidote for idleness and loneliness.
Science is a mighty ally of freedom—its advance has brought much
release from drudgery and from want. However, we must progress
still further. For better machines are not all that is needed to make
a better life. We shall have a better world only to the extent that our
social thinking and our social progress keep pace with the advance
of physical science.
We are approaching the days in this struggle when the basic chal-
lenge of the postwar years will become sharper and clearer. It isa
challenge that will ring out to people in all walks of life, to brains
and initiative, to cooperation of government and industry, to labor
and management, to religion and education. The answer will be
found in the minds and hearts of men and women intent upon preserv-
ing civilization and a world at peace.
In this month of Thanksgiving, let us be thankful that America and
her Allies have the strength and determination to hold high the eternal
torch of freedom. May the victory be a victory of lasting peace, so
that out of the bombed and shell-torn earth will come a happier to-
morrow for all mankind.
THE NEW MICROSCOPES?
By R. B. Srwet, M. D., and M. ELIzABETH WINTER
Philadelphia, Pa.
[With 5 plates]
It is, to speak conservatively, of extreme interest to review the
recent progress made by the scientist in his endeavor to penetrate the
unseen world of the minute and disease-causing organisms, in particu-
lar a world of viruses—suspected, yet lying just beyond the scope of
human vision and the power of the microscope to reveal; for the lab-
oratory research worker, the doctor, the technician long have been
familiar with the effects of these unseen enemies they have been called
upon to treat and to cope with in man, animal, and plant, and while
their knowledge of the infinitesimal has been growing steadily, they
were, until very recently, unable to make the slight step “beyond”
which would enable them to “see.” But today, science is exploring—
looking for the first time upon totally new worlds through the eyes of
totally new types of microscopes, microscopes new in principle of
construction and in principle of illumination.
THE ELECTRON MICROSCOPE
One of these new instruments, the electron microscope, has received
considerable attention and is now being used extensively in both in-
dustrial and medical research. Based on the principles of geometric
electron optics, this microscope utilizes electrons as a source of illumi-
nation instead of the light source of the ordinary light microscope.
Electrons, practically speaking, are the smallest, lightest particles of
matter and electricity. Like light, they behave like corpuscles guided
by waves. Unlike light, however, they travel in a straight line in a
vacuum where, subject to the action of electric and magnetic fields,
their behavior coincides with the laws and principles set down by Sir
William Hamilton who, more than a century ago, demonstrated the
existence of a close analogy between the path of a light ray through
refracting media and that of a particle through conservative fields of
force.
We know that these negatively charged particles, the electrons, re-
volving about in their various orbits in the atom, serve to maintain the

193
194. ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
balance of the atom while the nucleus exerts the “positive” force which
holds it together; and we also know that when this balance is upset,
due to gain or loss of electrons, we think of the atom as “charged,”
since it is this circumstance which causes the tiny particle to attract or
repel other electrons according to the state of its unbalance. And
science has succeeded in unbalancing the atoms to such an appreciable
extent that the negative electricity may be withdrawn and harnessed
for use in such instruments as the electron microscopes.
The fact has long been established that atoms are in a constant
state of vibration in a heated body and that the greater the heat of the
body, the greater the agitation of the atoms. According to the electron
theory of metals, electrons circulate about a three-dimensional network,
or lattice, of positive ions, some of the electrons being comparatively
free, that is to say, the attractions of the ions are practically canceled
by the repulsions of the other electrons. It does not necessarily follow,
however, that the same electrons consistently remain free. They may
be controlled by the ions eventually, but regardless of this, there is
always a fixed number of them that are free. Moreover, there is a
critical value of speed above which the electrons are able to rise in
metals and thus escape from their restraining positive charges, though
at ordinary temperatures the proportion of them moving rapidly
enough to do this is relatively small. However, as the heat applied
to the metal is increased, not only is the thermal agitation of the
electrons increased also, but the proportion among them possessing
sufficiently high speeds to enable them to leave the metal.
Thus is heat applied to the electron source of the electron micro-
scope which, in the case of most instruments of this kind, is a tungsten
filament surrounded by a guard cylinder. After leaving the filament,
or cathode, the electrons enter an electric field wherein are large
accumulations of charge which serve to speed up steadily the motion
of these freely moving particles. Since the electrons travel in vacua,
none of the kinetic energy gained in crossing the field is lost, the total
kinetic energy, or energy of motion, gained in passing through this
region being proportional to the voltage applied. We may deduce,
therefore, that since increase of charge in an electric field means a
proportional increase of kinetic energy of these electrons, the higher
the voltage applied, the greater the speed of the electrons—all of
which has been calculated mathematically and confirmed experi-
mentally.
After traversing the electric field and passing through the anode,
the electrons are concentrated on the specimen under examination by
the first of three magnetic fields which are created by currents flowing
through coils enclosed in soft iron shields, molded so as to concentrate

the magnetic fields on a short section of the microscope’s axis. Whereas
in the ordinary light microscope glass lenses serve as the refractive
media through which light rays are deflected, in the electron microscope
it is these magnetic fields of rotational symmetry which are the refrac-
tive media and serve as the “lenses” which deflect the beams of

electrons. The first of these, the condenser lens coil, corresponding to
the substage condenser of the ordinary light microscope, concentrates
the beam of electrons upon the specimen. The convergence of the
beam falling on the specimen is controlled by varying the current
through this condenser lens. Now, having passed through the speci-
men, the objective coil, similar in effect to the objective lens, focuses
the electrons, and an intermediate image enlarged about 100 diameters
196 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
is formed. Finally, the projection coil, corresponding to the projec-
tion lens or ocular, produces a further magnified image on a large
fluorescent screen. In some of the electron microscopes, there is a
periscope-like attachment by means of which it is possible to locate
and adjust for study the most interesting portion of the specimen, or
that which it is desired should be examined, before the projection lens
coil forms the final magnified image upon the screen, since it is some-
times difficult to accomplish this at high magnification. Also, if it
is desired that a photographic record be made, the screen can be
removed and a photographic plate substituted.
The specimen itself is supported on a thin nitrocellulose membrane
less than one-millionth of an inch thick, and clamped in the tip of a
cartridge which is inserted between the pole pieces of the objective coil.
The membrane is suspended across the opening of a fine-mesh screen,
and a plate, serving as the movable stage, supports the cartridge. The
image is projected onto the screen according to the density and atomic
weight of the specimen. In other words, whereas in the ordinary light
microscope the image is seen because of refraction of the specimen or
differences in absorption, in the electron microscope the image is seen
through scattering of the electrons, and since electrons travel in a
straight line in a vacuum, it stands to reason that even a fairly thin
specimen will prove sufficient to deflect such particles. Electrons
which strike a thick or solid portion of the specimen will, of course,
not continue on in a straight line to the screen but will be either com-
pletely absorbed by the specimen or scattered too far out of the beam,
thus failing to enter the narrow aperture of the objective, so that that
portion of the screen corresponding to the thick portion of the specimen
will remain dark. However, those electrons which are able to escape
complete absorption or too great deflection, because they do not happen
to come in contact with too solid a portion of the specimen and either
pass along on all sides of it or penetrate the thinner portions where it
is possible they may encounter only a single heavy nucleus for consider-
able scattering (the angle of deflection being proportional to the
square root of the thickness), continue on to the screen where they im-
pinge and cause the chemically treated screen to fluoresce, thus provid-
ing a study in light and shadow. If the atoms of a particular sub-
stance are heavy, they will also deflect more electrons than if they were
light. It may be readily seen, therefore, that the thinner the specimen
and its mounting, or the greater the variations in density of the speci-
men, the more internal structure and detail which may be seen, since
too great density tends to absorb or interrupt the straight-line progress
of too many of the electrons.
Focusing of the image is accomplished by varying the strength
of the fields and thereby altering the focal length of the “lens” coils at

will, so that the need of changing the specimen’s position in relation
to a fixed optical system, as would be the case with an ordinary light
microscope, is avoided. Thus, magnification in an electron micro-
scope can be continuously varied.
Some specimens may be mounted directly on the fine-mesh screen
while others may be embedded in collodion, sealed between films of
collodion, or suspended in a gelatin film, itself supported on collodion
film. The supporting films beside being very thin must be homo-
geneous lest an artifact be created. For the most part, no staining
of bacteriological specimens is done since usually they exhibit suffi-
ciently high contrast in density to reveal readily flagella and other de-
tail without any preparation except that of suspending the specimen in
distilled water or other liquid and allowing a drop of the suspension
to dry on the film surface, which method is also utilized for specimens
of colloidal particles, pigments, and other chemical preparations. At
times, however, as Dr. L. Marton, of Stanford University, has men-
tioned in his article on the electron microscope (written for The Jour-
nal of Bacteriology, March 1941, when he was associated with the
R. C. A. Research Laboratories), virus particles may show decided low
contrast. One method which Dr. Marton mentioned for overcoming
this is to obtain a number of electron micrographs at various focuses
and simply select the best one for study. Or the virus may be per-
mitted to absorb colloidal gold which would result in an image of high
contrast. Dr. Marton points out that there may be future need for a
staining in density and that already osmic acid has oe tried and used
for elite’ purpose.
In this microscope, voltages of between 30,000 and 60,000 are used.
It has been previously stated that the higher the voltage, the greater
the speed of the electrons. This might now be augmented to read,
the higher the voltage, the greater the speed of electrons; hence, the
shorter the wave length. An explanation of this may be approached
through a brief discussion of short-wave diffraction as considered by
Dr. Karl K. Darrow, of Bell Laboratories, in his book, “The Renais-
sance of Physics.” In order to obtain convenient angles of refraction
with the ordinary diffraction grating, it is necessary that the wave
lengths of light be smaller, but not many times smaller, than the spac-
ing between the wires or grooves. Naturally, a limit of measurement
is reached in the region of ultraviolet light since it is impossible to
lessen further the spacing of these gratings. However, this limitation
was overcome when von Laue conceived the idea of substituting a
erystal for an artificial grating since the atoms in a crystal are a
thousand times more closely set together than are the wires or grooves
of a grating and are arranged in precise regular order or “lattices,”
and, like gratings, are unable to diffract waves which are longer than
198 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
the spacings between their atoms. Von Laue suggested that if a beam
of light were directed across a crystal and made to strike a photo-
graphic plate, there would appear a spray of narrow rays each com-
posed of a single wave train instead of the broad fanlike arrange-
ment of the grating, and a pattern of starlike spots where the rays
come in contact with the plate instead of the dark irregular blot
when a grating is used. Of course, the rays are disposed according
to the spacings of the atoms in the lattice and according to the char-
acter of the lattice. Von Laue confirmed this idea for waves short
enough to be so diffracted and then advanced the theory that this
principle might hold true for X-rays as well, which theory was almost
immediately confirmed by Friedrich and Knipping. Shortly after
Schroedinger began to develop De Broglie’s wave theory of electrons,
Elsasser conceived the idea that possibly these tiny particles might
also be diffracted by crystals, and Doctors Davisson and Germer, of the
Bell Telephone Research Laboratories, using as part of their appara-
tus an electron gun, set out to test and to prove this theory. Due to
their experiments and those of G. P. Thomson, it was established
beyond a doubt that electron beams are diffracted just as are X-ray
beams. However, it was also demonstrated in the course of these ex-
periments that electrons of slow speeds and feeble kinetic energies are
unable to penetrate the crystals. It was Thomson who utilized faster
electrons and demonstrated that not only are electrons diffracted like
X-rays, but like X-rays also they make an imprint upon a photographic
plate at increased speeds. These three men, together with others, then
measured the wave lengths which they compared with the momenta
of these electrons by their diffraction. To these experiments and
measurements were then applied the following rules of correlation:
“Energy (/) is proportional to frequency (v), and momentum (Pp) is
inversely proportional to wavelength (lambda), the same constant (2)
appearing in both relations. (Frequency is interpreted as the velocity
(V) of the waves divided by their wavelength.)” These rules can be
applied mathematically to the electron microscope to illustrate better
the principles of its operation. In making use of the first rule, how-
ever, it is necessary to substitute “voltage” for “frequency,” and in so
doing, therefore, the rules of correlation explain the increase of energy
in relation to the increase of voltage as well as the increase of speed of
electrons in relation to the decrease or shortening of wave length when
we say the higher the voltage, the greater the speed; hence, the shorter
the wave length of electrons. It is interesting to note in passing that
a 150-volt electron has a wave length of one Angstrom unit, this being
more than 10-° times smaller than the wave length of visible or
ultraviolet light.
Because the wave lengths utilized in an electron microscope are so
much shorter than those employed in an ordinary light microscope,
NEW MICROSCOPES—SEIDEL AND WINTER 199
it is possible to obtain greatly increased resolution and magnification.
As a matter of fact, resolution up to 20,000 or 25,000 diameters may be
realized, and increased magnifications beyond this point up to 100,000,
even 200,000 diameters, can be obtained, such magnifications, however,
constituting enlargement of the image. (Definitions of “resolution”
and “magnification” discussed under “The Ordinary Microscope.”)
This high magnification is greatly desirable since otherwise the eye
would be unable to distinguish the fine detail of internal structure at
a resolution of the order of 25,000. Asa result of this increase in reso-
lution and magnification over that of the ordinary light microscope
which is between 1,600 and 2,500 diameters and in the ultramicroscope
between 2,500 and 5,000 diameters, many surface cells and much intri-
cate internal structure hitherto unsuspected, or at least undetected by
ordinary microscopes, have been revealed. To cite a few examples:
The streptococcal cells appear, not as individual cells, that is, sepa-
rate and apart from one another, but as chainlike groups, the cells in
each chain being bound together apparently by the strong rigid mem-
brane or outer cellular wall which extends over a number of these cells
and which is so plainly evident under the electron microscope. Sub-
jected to sonic vibraticn, these cells suffer a loss of protoplasmic mate-
rial from their interior, causing them to become mere “ghost” cells,
which makes them more transparent to electron beams. That there
exists considerable difference between the surface structure and in-
ternal composition of these cells has also been determined and
demonstrated.
Using the electron microscope, Dr. Harry E. Morton, of the depart-
ment of bacteriology of the University of Pennsylvania Medical
School, and Dr. Thomas F. Anderson, of R. C. A. Research Labora-
tories were able to demonstrate that in at least one instance where
chemical reaction is induced by bacteria this reaction takes place
“inside” the cells. The fact that diphtheria bacilli reduce potassium
tellurite to metallic tellurium has been known for some time, but
whether this reaction occurred inside the cell or on the cell surface
or both had never been definitely shown until the electron microscope
was made available. Then, obtaining unstained preparations of
Corynebacterium diphtheriae grown on blood infusion agar, Drs.
Morton and Anderson demonstrated that the typical polar granules
appear as dense spherical masses, or possibly plates, of a very black
color and that in unstained preparations of this same Corynebacterium
diphtheriae grown on potassium tellurite chocolate agar, not only the
polar granules are in evidence but also the tiny needlelike crystals
inside the cell which disappear along with the black color of the cell
masses when a drop of bromine water is added to 1 ce. of a suspension
619830—45——14
200 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
of the cells on potassium tellurite chocolate agar. From this the
experimenters were able to deduce that tellurium metal occurs in the
form of needles and is the cause of the black color, and that this reac-
tion occurs within the cells since the crystals have never been observed
to lie totally outside the cell wall, although at times there is some
distortion of the wall.
The electron microscope also affords such study and observation
as that carried out by Dr. W. M. Stanley, of the Rockefeller Institute
of Medical Research, and Dr. Thomas F. Anderson in their recent
investigation of plant viruses. By means of electron micrographs,
they were able to judge the exact manner and extent of attack made
on the tobacco mosaic virus by the protein antibodies in the blood
stream of rabbits in which an artificial immunity to the virus had been
produced.
Structures like that of the spirochete of Weil’s disease, typhoid
flagella, unusual internal structure of pertussis organisms, tubercle
bacilli, the isolation and recognition of the influenza virus, the spores
of trychophyton mentagrophytes, Spirochaeta pallida with its accom-
panying flagellar appendages, and colloidal particles are but a few
of the interesting revelations of the electron microscope for medical
science. Industrial science, too, has found this new research tool of
great value in the study of metals, alloys, and plastics, as well as in
the study of size, shape, and distribution of particles in chemical com-
pounds and elements.
The electron microscope herein described is that manufactured by
the Radio Corporation of America. There are, of course, variations
in construction of the different instruments of this kind but all types
are built along similar lines and upon the same general principles.
In the electron microscope there is some aberration plus the additional
disadvantages of having the specimen in a vacuum, not to mention the
probable protoplasmic changes induced by the terrific bombardment
of electrons, and finally, what is perhaps the greatest disadvantage
insofar as medical science is concerned—that of being unable to view
living organisms. Nevertheless, the disadvantages of the microscope
are far overshadowed by its increased resolving and magnification
powers which have combined to make it an invaluable research tool.
RESOLUTION AND MAGNIFICATION OF ORDINARY MICROSCOPE
We have stated that the resolving power of the ordinary light
microscope is restricted to between 1,600 and 2,500 diameters and
that of the ordinary ultramicroscope to between 2,500 and 5,000
diameters, resolution in any microscope being the ability of the in-
strument to reveal the most minute of component parts of a specimen
so that each may be seen as a distinct and separate image. For in-
NEW MICROSCOPES—SEIDEL AND WINTER 201
stance, let us suppose an object is examined through which run two
very fine parallel lines closely set together. If the two lines are visible
under the microscope and are revealed as two separate images, then,
apparently, no limit of resolution has been reached; but if the two
lines are merged or revealed as only one, and upon further magnifica-
tion the image merely becomes enlarged without separation of the
lines, then a limit of resolution apparently has been reached and ad-
ditional magnification would constitute only enlargement. Assum-
ing now that the object is a point object in which case the images of
the points would be diffraction disks, the disks should likewise be
sufficiently resolved so that each may be distinguished as a single
image. If, when these disks are seen to overlap, additional magnifica-
tion fails to extend the distance between them, their size simply in-
creasing in proportion to the increase of magnification, or, if they are
all but completely merged and the image becomes just a spurious disk
of light, it is evident that a definite limit of resolution has been at-
tained and that further magnification would be useless. Resolution,
in a broad sense, then, is the ability of the microscope to bring out or
reveal internal structure and detail of a specimen, the shortest dis-
tance it is possible to separate two component parts, according to
Abbe, being not less than the wave length of light by which the
specimen is illuminated divided by the numerical aperture of the
objective lens plus the numerical aperture of the condenser lens, or
about one-third the wave length of light utilized.
The several factors which are generally acknowledged to be re-
sponsible for the limitation of resolving power are interrelated. Now
when light passes from one medium into another of different density—
in the instance which we are considering that of light refracted by the
specimen and passing from air into glass—the light rays are deviated
from their straight-line course; that is to say, when they come to
within a very short distance of this denser medium, they are acted upon
by a very powerful force in such a manner that they execute a short,
rapidly curving motion, or an angle, and are pulled into the medium of
greater density. When the rays of light undergo such a force, the
momentum of the corpuscles is increased and the speed of the waves
decreased, resulting, of course, in a shortening of the wave lengths.
Here, again, we may make use of the second of the rules of correlation—
“Momentum (of corpuscles) varies inversely as wavelength (of
waves).” Once well inside the new medium, however, the light rays
straighten themselves out again (unless the medium is so constructed
that it possesses gradation of density, in which case they follow a curved
path). They do this in spite of the fact that the same forces are still
acting upon them, although now these forces issue from all sides of
them and so cancel each other out, the momentum of the photons or
202 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
light corpuscles continuing to increase while the speed of the waves is
proportionately retarded. If the light is refracted normally to the
surface, however, it does not bend, but tends to cause a shortening of
the optical path although the wave length is shortened regardless. It
is only when it is refracted obliquely to the surface that the light is
bent, the greater the obliquity of the incident ray and the denser
the medium, the greater the bending of the angle of the cone of light
and the shorter the wave length. It might therefore seem desirable to
obtain as great an angle of refraction as possible. However, shorten-
ing of the wave length is not in exact proportion to the amount of
bending except in the case of the diffraction grating. And regardless
of how great a change there is in its angle, the numerical aperture of
the light, or angular aperture as it is more properly called, remains
constant.
In order, then, that the cone of light be large enough to supply the
aperture of the objective with sufficient hight to produce an accurate,
bright, and enlarged image of the specimen, it is first necessary that
the specimen be refracting or emitting light of an adequate quantity,
since both magnification and resolution are largely dependent upon the
amount of light which the objective utilizes and receives into the tube
of the microscope and since such hight as the objective does receive
should be only that emitted by the specimen. It is obvious, therefore,
that it is of primary importance for the specimen itself to be amply
illuminated. This would seem to depend entirely on the actual light
source, yet no matter how powerful a light source is employed, it is of
little avail unless the condenser is of sufficient quality and aperture
dimensions to accommodate the light which it receives from the source.
If, for instance, the numerical aperture of the objective is 1.25, the
width of the cone of light emanating from the specimen should com-
pletely fill this aperture in order for the fullest powers of the micro-
scope to be realized. Now, since the condenser supplies the light to the
specimen, it stands to reason that it, also, should have a numerical
aperture of at least 1.25. However, if the condenser and specimen
slide are separated by air, the condenser can provide light of only
1.00 N. A. to the specimen since, according to a law of optics, no aper-
ture greater than 1.00 N. A. (this being the refractive index of air),
can pass from a denser medium into air. To remedy this situation,
an immersion fluid is placed between the top of the condenser and the
lower side of the specimen slide as well as between the specimen and
the objective lens.
Since no optical medium has an index of refraction greater than
3 and no immersion fluid an index of refraction greater than 1.7, to
increase resolving power further, then, might it not be feasible to
widen the apertures of the objective and condenser lenses, thus afford-
NEW MICROSCOPES—SEIDEL AND WINTER 203
ing additional illumination for utilization by both specimen and objec-
tive? This idea would be entirely practical except for the fact that
such enlargement of the lenses would increase aberration, both spher-
ical and chromatic, and apparently present-day lenses are now as highly
corrected as it is possible for human ingenuity and skillful workman-
ship tomake them. Spherical aberration, caused by the paraxial rays
coming to a focus at the center of the lens before those rays near the
principal axis, is corrected by using concave and convex lenses of
different material and, consequently, of different refractive index. In
this manner spherical aberration of a convex lens, for instance, can be
overcome, without its converging action being altered, by adding to
the optical system a concave lens in which there is an equal and oppo-
site aberration. Chromatic aberration, occurring when more than
one wave length of light is used to illuminate the specimen, is due to the
fact that the shortest waves of the spectrum are refracted most and
the longest waves least, thus causing the blue-violet waves to come to
a focus ahead of the red waves and resulting in a series of colored foci
all along the axis. Now since, as we have said, the shortening of the
different groups of wave lengths is not in exact proportion to their
bending and since this circumstance varies according to the substance
the light rays pass through, it is possible to combine lenses or lens
systems in such a way that white light may be obtained. For instance,
a small concave flint-glass prism produces the same amount of dis-
persion as a large convex crown-glass prism. Thus, if these two prisms
are placed with their edges opposite, the crown glass will bring together
the spectrum produced by the flint glass and white light will be the
result. However, the rays of white light will not extend parallel with
the original direction but will bend toward the base of the crown glass
since the mean refraction of the crown glass is greater than that of the
flint glass. Achromatic objectives, corrected spherically for one color,
chromatically for two ; semiapochromatic objectives, possessing moder-
ate refractive indices and very small dispersion, in which a lens of
fluorite is substituted for one of the glass lenses; apochromatic objec-
tives, corrected spherically for two colors, chromatically for three; and
also certain monochromatic lenses for use with light of one wave
length only are available for overcoming, at least in part, one of the
conditions which tends to interfere with better resolution. Con-
densers, also, can be corrected for both spherical and chromatic aber-
ration and must be achromatic-aplanatic if the light which enters the
objective is to come only from the specimen, for condensers with spher-
ical and chromatic aberration are unable to direct their entire cone of
light upon the specimen.
In addition to being as highly corrected as possible and possessing a
large numerical aperture, an objective should also be capable of ade-
204 § ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
quately magnifying the image, being aided in this by the ocular which
also serves at times to compensate for the defects in chromatic magnifi-
cation which cannot be managed conveniently by high-power objec-
tives, the magnification of the final image being the product of the
magnification of the objective multiplied by the magnification of the
ocular. An amplifier is sometimes inserted between the objective and
ocular which causes the rays of light from the objective to diverge to
a greater extent, thus doubling the size of the image. Magnification
may also be improved by increasing the tube length, by increasing the
distance from which the image is projected, and by altering the posi-
tions of the various lenses in an adjustable objective. In general, the
greater the magnification, the smaller will be the specimen field, but,
as has been stressed, high powers of magnification should always be
accompanied by equally high powers of resolution.
As we have seen, resolution in the ordinary light microscope is
definitely restricted by a number of interrelated elements. Even when
monochromatic light is employed, there is always present some spheri-
cal aberration with which to contend. True, better visibility of speci-
mens is provided by dark-field microscopy in which the specimen is
viewed by the high contrast of its own scattered or reflected light
against a dark field, although in this type of illumination objects in
the field must be well separated. Much fine detail and brilliant color
of specimens can be observed by means of the polarization of light.
Further, it is possible to illuminate the specimen with shorter and
shorter wave lengths of light, the shorter the wave length of light used,
the more of the fine detail of the specimen which can be seen, but a
limit is reached here, also, for ordinary glass lenses are not transparent
to ultraviolet rays. However, in the ultraviolet microscope, having a
resolution twice that of the instruments using “visible light,” the con-
denser, objective, and ocular are all made of quartz and, by substituting
the photographic plate for direct observation, many excellent micro-
graphs of numerous varieties of organisms and cellular structures can
be made. But when viewed directly, nothing of the nature or struc-
ture of the specimen can be ascertained; only the light scattered by the
specimen is distinguishable, the size of the specimen being roughly
estimated by the amount of light refracted.
These seemingly unsurmountable obstacles of the ordinary micro-
scopes would appear to indicate that Abbe’s law and the contention of
physicists that “any object which is smaller than one-half the wave
length of light by which it is illuminated cannot be seen in its true form
or detail” are destined to remain undefied.
REDUCTION IN THEORETICAL LIMIT OF RESOLUTION DEMONSTRATED
But Dr. Francis F. Lucas, of the Bell Telephone Research Labora-
tories, and Drs. Louis Cary] Graton and E. C. Dane, Jr., of the depart-
NEW MICROSCOPES—SEIDEL AND WINTER 205
ment of geology, Harvard University, have very convincingly demon-
strated a reduction in these theoretical limits of resolution and visibility
with their instruments, designed for use in the visible light region of
the spectrum.
The Graton-Dane microscope is mounted on a 360-kg. steel founda-
tion bed which, in turn, is supported by six rubber-in-sheer marine-
engine mountings—this for the purpose of eliminating all vibration
and insuring stability of parts, two factors upon which both men have
laid great stress. Any type source, such as the carbon arc, metallic arc,
incandescent filament, Point-O-Lite, mercury vapor, or any of the
special forms of monochromators, can be used for illuminating the
specimen with direct and dark-field transmitted, vertical and oblique
reflected, or polarized light. The image beam itself follows a straight-
line path in passing from the objective, the objective ranging anywhere
from the shortest to the greatest in working distance, through the tube
to the ocular, as few lenses as possible being placed in its way. The
spiral-cut rack and pinion which moves the stage and substage assem-
bly in longitudinal tracks or guides can be operated by hand or by an
electric motor and is independent of the fine adjustment, also motor-
driven, which moves only the objective and the carriage carrying the
objective. Whereas manual operation of the fine adjustment which is
100 times more sensitive than that of the ordinary instruments neces-
sitates 500 turns of the knob to move the objective a distance of but
1 millimeter (an adjustment calculated to require a time period of
25 minutes), by means of the motor it is possible to move the objective
at the rate of 0.01 mm. per second or 0.004 mm. per second, depending
upon which of the two speeds is desired, rapid motion being used when
the image appears considerably out of focus and decreased speed being
used when the image seems to be reaching a point of perfection
Resolution up to 6,000 diameters and magnification up to 50,000
diameters have been achieved with this high-precision microscope
which photographs or enables observation of both opaque and trans-
parent preparations; in fact, polishing scratches measuring in width
but one-tenth the wave length of light used have been clearly distin-
?The mechanism governing the fine adjustment was completely redesigned after it was
discovered that changes in the lubricant, used for gear threads and carriage bearings,
seriously affected the precision of the instrument. Using a principle suggested to him by
R. W. Vose, formerly of the Harvard Engineering School, Dr. Dane built and assembled
a new fine-adjustment drive so designed that, as Dr. Graton describes it, “all that part
of the mechanism which actuates the slowest, and therefore the most sensitive, part
of the motion operates not through gears or screws, but through the differential flexing of a
train of spring-bronze strips, which have the double advantage of avoiding all chance for
play or backlash and of needing no lubrication whatever. Interferometer tests with the
new element in place give practically ideal readings as compared with the theoretical:
the deviations are very much smaller than those recorded in our original paper, page 372.
The operation of the fine-focusing mechanism selectively by hand knob or by motor-drive,
and the slowness of motion, and hence the precise control over focus are the same in the
new design as in the old.”
206 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
guished. It is the opinion of both Dr. Graton and Dr. Dane that
some present-day lenses are really capable of better resolution than
claimed for them by their manufacturers, it having been their experi-
ence to use objectives exhibiting superior qualities of resolution over
those of identical medium and numerical aperture, proving that not
only have already available lenses surpassed their theoretical limits of
resolution, indicating that it might be possible to design objectives
with still greater numerical apertures, but that the accepted theory
regarding this resolution is sadly in need of revision. Dr. Lucas’s
microscope utilizing an objective with a numerical aperture of 1.60, for
instance, in combination with monobromnaphalene immersion fluid,
also yields resolution up to 6,000 diameters being, like the Graton-
Dane scope, a high-precision instrument constructed with the idea of
maintaining absolute stability of parts. Dr. Lucas also has expressed
doubt as to the complete validity of the generally accepted theory of
resolution.
In working with a high-precision ultraviolet microcamera, into
which a tricolor filter system has been incorporated, which he has just
recently perfected, Dr. Lucas is able to obtain a minimum magnifica-
tion of 30,000 diameters and a maximum magnification of 60,000 diam-
eters. With this instrument it is possible to view living cells and
organisms, no staining or killing of organisms being necessary, and
Dr. Lucas has succeeded in obtaining excellent photomicrographs
(both still and motion pictures). Of special significance to industry,
for instance, is the ability of this scope to demonstrate the size, shape,
and reactions in motion and aflinity of the tiny particles of which
rubber is composed under varying conditions of temperature, etc.,
while its ability to reveal living rat and mouse sarcoma and carcinoma
cells and to demonstrate the development and behavior of the syphilitic
organism is of far more than average interest to medical science.
England’s Dr. J. E. Barnard has succeeded in obtaining resolution
up to 7,500 diameters with his ultra-dark-field scope in which he uses a
combined illuminator. In this, an outer system of glass acts as the
immersion dark-field illuminator while the inner immersion system of
quartz makes possible the passage of a transmitted beam of light
through the specimen. Both condensers have the same focus, one for
visible light, the other for ultraviolet radiation, and both can be
stopped out at will. When, for instance, bacteria are being observed,
immersion contact is made between the condenser and quartz slide,
the dark-field illuminator being used, thus revealing the bacteria with
visible light. When the dark-field illuminator is closed, however, a
beam of ultraviolet light may be directed up through the quartz con-
denser and focused on the bacteria. The object-glass, of course, has
to be adjusted since it does not possess the same focus for ultraviolet
NEW MICROSCOPES—-SEIDEL AND WINTER 207
that it does for visible light. Staining of specimens is thus unneces-
sary, making it possible to secure photomicrographs of living minute
organisms.
In addition to these four microscopes, a fourth, belonging to the
Canadian Department of Mines and located at Ottawa, and almost
identical in principle and construction to that of Drs. Dane and
Graton, has demonstrated ability to attain equally high resolution.
This, like the scopes of Drs. Dane, Graton, and Lucas, is fitted
with a tube for visual observation although intended mainly for
microphotographical work in the field of metallurgy. It is Dr.
Graton’s belief, however, that his instrument and that of Dr. Dane
might also be adaptable to the purposes of biological research. Re-
ferring, in the description of their “Precision, All Purpose Micro-
camera” (Journ. Opt. Soc. Amer.), to the necessity or “desirability” of
“reéxamining the classical conception of the limit of useful magnifi-
cation,” Drs. Dane and Graton have this to say:
So long as the makers accepted the conventional limit as valid and had already
attained it, there was little incentive toward progress. But with that limit
apparently surpassed, there is no present knowledge as to how far ahead the
true limit may lie. If present-day objectives do substantially better than the
“limit” for which they were designed, is it not reasonable to suppose that effort
to do better stil] may conceivably be rewarded?
To such an inquiry there can be but one logical answer—an agree-
ment which, while perhaps not concurred in by all, must, for those
stimulated to more intense interest and effort by the possibilities of
uncovering new facts, pose further questions; for, if the improvement
of one part results in the improved performance of the whole, is it not
also reasonable to suppose that additional changes of additional parts,
yes, even changes with respect to principle and method might likewise
bear fruit ?
THE UNIVERSAL MICROSCOPE
It is not only a reasonable supposition, but already, in one instance,
a very successful and highly commendable achievement on the part of
Dr. Royal Raymond Rife of San Diego, Calif., who, for many years,
has built and worked with light microscopes which far surpass the
theoretical limitations of the ordinary variety of instrument, all the
Rife scopes possessing superior ability to attain high magnification
with accompanying high resolution. The largest and most powerful
of these, the universal microscope, developed in 1933, consists of 5,682
parts and is so called because of its adaptability in all fields of miero-
scopical work, being fully equipped with separate substage condenser
units for transmitted and monochromatic beam, dark-field, polarized,
and slit-ultra illumination, including also a special device for crystal-
lography. ‘The entire optical system of lenses and prisms as well as
208 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
the illuminating units are made of block-crystal quartz, quartz being
especially transparent to ultraviolet radiations.
The illuminating unit used for examining the filterable forms of
disease organisms contains 14 lenses and prisms, 3 of which are in the
high-intensity incandescent lamp, 4 in the Risley prism, and 7 in the
achromatic condenser which, incidentally, has a numerical aperture
of 1.40. Between the source of light and the specimen are subtended
two circular, wedge-shaped, block-crystal quartz prisms for the pur-
pose of polarizing the light passing through the specimen, polarization
being the practical application of the theory that light waves vibrate in
all planes perpendicular to the direction in which they are propagated.
Therefore, when light comes into contact with a polarizing prism, it
is divided or split into two beams, one of which is refracted to such an
extent that it is reflected to the side of the prism without, of course,
passing through the prism while the second ray, bent considerably less,
is thus enabled to pass through the prism to illuminate the specimen.
When the quartz prisms on the universal microscope, which may be
rotated with vernier control through 360°, are rotated in opposite
directions, they serve to bend the transmitted beams of light at variable
angles of incidence while, at the same time, a spectrum is projected
up into the axis of the microscope, or rather a small portion of a spec-
trum since only a part of a band of color is visible at any one time..
However, it is possible to proceed in this way from one end of the spec-
trum to the other, going all the way from the infrared to the ultra-
violet. Now, when that portion of the spectrum is reached in which
both the organism and the color band vibrate in exact accord, one with
the other, a definite characteristic spectrum is emitted by the organism.
In the case of the filter-passing form of the Bacillus typhosus, for
instance, a blue spectrum is emitted and the plane of polarization
deviated plus 4.8°. The predominating chemical constituents of the
organism are next ascertained after which the quartz prisms are ad-
justed or set, by means of vernier control, to minus 4.8° (again in the
case of the filter-passing form of the Bacillus typhosus) so that the
opposite angle of refraction may be obtained. A monochromatic
beam of light, corresponding exactly to the frequency of the organism
(for Dr. Rife has found that each disease organism responds to and
has a definite and distinct wave length, a fact confirmed by British
medical research workers) is then sent up through the specimen and
the direct transmitted light, thus enabling the observer to view the
organism stained in its true chemical color and revealing its own
individual structure in a field which is brilliant with light.
The objectives used on the universal microscope are a 1.12 dry lens,
a 1.16 water immersion, a 1.18 oil immersion, and a 1.25 oil immersion.
The rays of light refracted by the specimen enter the objective and are
NEW MICROSCOPES—SEIDEL AND WINTER 209
then carried up the tube in parallel rays through 21 light bends to the
ocular, a tolerance of less than one wave length of visible light only
being permitted in the core beam, or chief ray, of illumination. Now,
instead of the light rays starting up the tube in a parallel fashion,
tending to converge as they rise higher and finally crossing each other,
arriving at the ocular separated by considerable distance as would be
the case with an ordinary microscope, in the universal tube the rays
also start their rise parallel to each other but, just as they are about te
cross, a specially designed quartz prism is inserted which serves to
pull them out parallel again, another prism being inserted each time
the rays are about ready to cross. These prisms, inserted in the tube,
which are adjusted and held in alignment by micrometer screws of 100
threads to the inch in special tracks made of magnelium (magnelium
having the closest coefficient of expansion of any metal to quartz), are
separated by a distance of only 30 millimeters. Thus, the greatest
distance that the image in the universal is projected through any one
media, either quartz or air, is 30 millimeters instead of the 160, 180,
or 190 millimeters as in the empty or air-filled tube of an ordinary
microscope, the total distance which the light rays travel zigzag fashion
through the universal tube being 449 millimeters, although the physical
length of the tube itself is 229 millimeters. It will be recalled that if
one pierces a black strip ef paper or cardboard with the point of a
needle and then brings the card up close to the eye so that the hole is
in the optic axis, a small brilliantly lighted object will appear larger
and clearer, revealing more fine detail, than if it were viewed from the
same distance without the assistance of the card. This is explained
by the fact that the beam of light passing through the card is very
narrow, the rays entering the eye, therefore, being practically parallel,
whereas without the card the beam of light is much wider and the
diffusion circles much larger. It is this principle of parallel rays in
the universal microscope and the resultant shortening of projection
distance between any two blocks or prisms plus the fact that objectives
can thus be substituted for oculars, these “oculars” being three matched
pairs of 10-millimeter, 7-millimeter, and 4-millimeter objectives in
short mounts, which make possible not only the unusually high mag-
nification and resolution but which serve to eliminate all distortion as
well as all chromatic and spherical aberration.
Quartz slides with especially thin quartz cover glasses are used when
a tissue section or culture slant is examined, the tissue section itself also
being very thin. An additional observational tube and ocular which
yield a magnification of 1,800 diameters are provided so that that por-
tion of the specimen which it is desired should be examined may be
located and so that the observer can adjust himself more readily when
viewing a section at a high magnification.
210 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
The universal stage is a double rotating stage graduated through
360° in quarter-minute arc divisions, the upper segment carrying
the mechanical stage having’ a movement of 40°, the body assembly
which can be moved horizontally over the condenser also having an
angular tilt of 40° plus or minus. Heavily constructed joints and
screw adjustments maintain rigidity of the microscope which weighs
200 pounds and stands 24 inches high, the bases of the scope being
nickel cast-steel plates, accurately surfaced, and equipped with three
leveling screws and two spirit levels set at angles of 90°. The coarse
adjustment, a block thread screw with 40 threads to the inch, slides
in a 114 dovetail which gibs directly onto the pillar post. The weight
of the quadruple nosepiece and the objective system is taken care of
by the intermediate adjustment at the top of the body tube. The
stage, in conjunction with a hydraulic lift, acts as a lever in operating
the fine adjustment. A 6-gauge screw having 100 threads to the inch
is worked through a gland into a hollow, glycerine-filled post, the
glycerine being displaced and replaced at will as the screw is turned
clockwise or anticlockwise, allowing a 5-to-1 ratio on the lead screw.
This, accordingly, assures complete absence of drag and inertia. The
fine adjustment being 700 times more sensitive than that of ordinary
microscopes, the length of time required to focus the universal ranges
up to 114 hours which, while on first consideration, may seem a dis-
advantage, is after all but a slight inconvenience when compared
with the many years of research and the hundreds of thousands of
dollars spent and being spent in an effort to isolate and to look upon
disease-causing organisms in their true form.
Working together back in 1931 and using one of the smaller Rife
microscopes having a magnification and resolution of 17,000 diameters,
Dr. Rife and Dr. Arthur Isaac Kendall, of the department of bac-
teriology of Northwestern University Medical School, were able to
observe and demonstrate the presence of the filter-passing forms of
Bacillus typhosus. An agar slant culture of the Rawlings strain of
Bacillus typhosus was first prepared by Dr. Kendall and inoculated
into 6 cc. of “Kendall” K Medium, a medium rich in protein but poor
in peptone and consisting of 100 mg. of dried hog intestine and 6 ce.
of tyrode solution (containing neither glucose nor glycerine) which
mixture is shaken well so as to moisten the dried intestine powder
and then sterilized in the autoclave, 15 pounds for 15 minutes, altera-
tions of the medium being frequently necessary depending upon the
requirements for different organisms. Now, after a period of 18 hours
in this K Medium, the culture was passed through a Berkefeld “N”
filter, a drop of the filtrate being added to another 6 cc. of K Medium
and incubated at 87° C. Forty-eight hours later this same process
was repeated, the “N” filter again being used, after which it was noted
NEW MICROSCOPES—SEIDEL AND WINTER 211
that the culture no longer responded to peptone medium, growing now
only in the protein medium. When again, within 24 hours, the culture
was passed through a filter—the finest Berkefeld “W” filter, a drop
of the filtrate was once more added to 6 cc. of K Medium and incubated
at 37° C., a period of 3 days elapsing before the culture was transferred
to K Medium and yet another 3 days before a new culture was pre-
pared. Then, viewed under an ordinary microscope, these cultures
were observed to be turbid and to reveal no bacilli whatsoever. When
viewed by means of dark-field illumination and oil-immersion lens,
however, the presence of small, actively motile granules was estab-
lished, although nothing at all of their individual structure could be
ascertained. Another period of 4 days was allowed to elapse before
these cultures were transferred to K Medium and incubated at 37° C.
for 24 hours when they were then examined under the Rife microscope
where, as was mentioned earlier, the filterable typhoid bacilli, emitting
a blue spectrum, caused the plane of polarization to be deviated plus
4.8°. Then when the opposite angle of refraction was obtained by
means of adjusting the polarizing prisms to minus 4.8° and the cultures
illuminated by a monochromatic beam coordinated in frequency with
the chemical constituents of the typhoid bacillus, small, oval, actively
motile, bright turquoise-blue bodies were observed at a magnification
of 5,000 diameters, in high contrast to the colorless and motionless
debris of the medium. These observations were repeated eight times,
the complete absence of these bodies in uninoculated control K Media
also being noted.
To further confirm their findings, Drs. Rife and Kendall next
examined 18-hour-old cultures which had been inoculated into K
Medium and incubated at 37° C., since it is just at this stage of growth
in this medium and at this temperature that the cultures become
filterable. And, just as had been anticipated, ordinary dark-field ex-
amination revealed unchanged, long, actively motile bacilli; bacilli
having granules within their substance; and free-swimming, actively
motile granules; while under the Rife microscope were demonstrated
the same long, unchanged, almost colorless bacilli; bacilli, practically
colorless, inside and at one end of which was a turquoise-blue granule
resembling the filterable forms of the typhoid bacillus; and free-swim-
ming, small, oval, actively motile, turquoise-blue granules. By trans-
planting the cultures of the filter-passing organisms or virus into a
broth, they were seen to change over again into their original rodlike
forms.
At the same time that these findings of Drs. Rife and Kendall were
confirmed by Dr. Edward C. Rosenow, of the Mayo Foundation, the
magnification with accompanying resolution of 8,000 diameters of the
Rife microscope, operated by Dr. Rife, was checked against a dark-
212 § ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
field oil-immersion scope operated by Dr. Kendall and an ordinary
2-mm. oil-immersion objective, X 10 ocular, Zeiss scope operated by
Dr. Rosenow at a magnification of 900 diameters. Examinations of
gram- and safranin-stained films of cultures of Bacillus typhosus,
gram- and safranin-stained films of cultures of the streptococcus from
poliomyelitis, and stained films of blood and of the sediment of the
spinal fluid from a case of acute poliomyelitis were made with the
result that bacilli, streptococci, erythrocytes, polymorphonuclear
leukocytes, and lymphocytes measuring nine times the diameter of the
same specimens observed under the Zeiss scope at a magnification and
resolution of 900 diameters, were revealed with unusual clarity. Seen
under the dark-field microscope were moving bodies presumed to be
the filterable turquoise-blue bodies of the typhoid bacillus which, as
Dr. Rosenow has declared in his report (Observations on filter-passing
forms of Eberthella typhi—Bacillus typhosus—and of the streptococ-
cus from poliomyelitis, Proc. Staff Meetings Mayo Clinic, July 13,
1932), were so “unmistakably demonstrated” with the Rife microscope,
while under the Zeiss scope stained and hanging-drop preparations of
clouded filtrate cultures were found to be uniformly negative. With
the Rife microscope also were demonstrated brownish-gray cocci and
diplococci in hanging-drop preparations of the filtrates of strepto-
coccus from poliomyelitis. These cocci and diplococci, similar in size
and shape to those seen in the cultures although of more uniform in-
tensity, and characteristic of the medium in which they had been
cultivated, were surrounded by a clear halo about twice the width of
that at the margins of the debris and of the Bacillus typhosus. Stained
films of filtrates and filtrate sediments examined under the Zeiss micro-
scope, and hanging-drop, dark-field preparations revealed no organ-
isms, however. Brownish-gray cocci and diplococci of the exact same
size and density as those observed in the filtrates of the streptococcus
cultures were also revealed in hanging-drop preparations of the virus
of poliomyelitis under the Rife microscope, while no organisms at all
could be seen in either the stained films of filtrates and filtrate sedi-
ments examined with the Zeiss scope or in hanging-drop prepara-
tions examined by means of the dark-field. Again using the Rife
microscope at a magnification of 8,000 diameters, numerous nonmotile
cocci and diplococci of a bright-to-pale pink in color were seen in
hanging-drop preparations of filtrates of Herpes encephalitic virus.
Although these were observed to be comparatively smaller than the
cocci and diplococci of the streptococcus and poliomyelitic viruses,
they were shown to be of fairly even density, size, and form and sur-
rounded by ahalo. Again, both the dark-field and Zeiss scopes failed to
reveal any organisms, and none of the three microscopes disclosed the
NEW MICROSCOPES—SEIDEL AND WINTER 213
presence of such diplococci in hanging-drop preparations of the filtrate
of a normal rabbit brain. Dr. Rosenow has since revealed these organ-
isms with the ordinary microscope at a magnification of 1,000 diam-
eters by means of his special staining method and with the electron
microscope at a magnification of 12,000 diameters. Dr. Rosenow has
expressed the opinion that the inability to see these and other similarly
revealed organisms is due, not necessarily to the minuteness of the
organisms, but rather to the fact that they are of a nonstaining, hyaline
structure. Results with the Rife microscopes, he thinks, are due to
the “ingenious methods employed rather than to excessively high
magnification.” He has declared also, in the report mentioned pre-
viously, that “Examination under the Rife microscope of specimens
containing objects visible with the ordinary microscope, leaves no
doubt of the accurate visualization of objects or particulate matter by
direct observation at the extremely high magnification obtained with
this instrument.”
Exceedingly high powers of magnification with accompanying high
powers of resolution may be realized with all of the Rife microscopes,
one of which, having magnification and resolution up to 18,000 diam-
eters, is now being used at the British School of Tropical Medicine in
England. In a recent demonstration of another of the smaller Rife
scopes (May 16, 1942) before a group of doctors including Dr. J. H.
Renner, of Santa Barbara, Calif.; Dr. Roger A. Schmidt, of San
Francisco, Calif.; Dr. Lois Bronson Slade, of Alameda, Calif.; Dr.
Lucile B. Larkin, of Bellingham, Wash.; Dr. E. F. Larkin, of Belling-
ham, Wash.; and Dr. W. J. Gier, of San Diego, Calif., a Zeiss ruled
grading was examined, first under an ordinary commercial micro-
scope equipped with a 1.8 high dry lens and X 10 ocular, and then
under the Rife microscope. Whereas 50 lines were revealed with the
commercial instrument and considerable aberration, both chromatic
and spherical noted, only 5 lines were seen with the Rife scope, these
5 lines being so highly magnified that they occupied the entire field,
without any aberration whatsoever being apparent. Dr. Renner, in a
discussion of his observations, stated that “The entire field to its very
edges and across the center had a uniform clearness that was not true
in the conventional instrument.” Following the examination of the
grading, an ordinary unstained blood film was observed under the same
two microscopes. In this instance, 100 cells were seen to spread
throughout the field of the commercial instrument while but 10 cells
filled the field of the Rife scope.
The universal microscope, of course, is the most powerful Rife
scope, possessing a resolution of 31,000 diameters and magnification
of 60,000 diameters. With this it is possible to view the interior of the
214 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
“pin-point” cells, those cells situated between the normal tissue cells
and just visible under the ordinary microscope, and to observe the
smaller cells which compose the interior of these pin-point cells.
When one of these smaller cells is magnified, still smaller cells are seen
within its structure. And when one of the still smaller cells, in its turn,
is magnified, it, too, is seen to be composed of smaller cells. Each
of the 16 times this process of magnification and resolution can be
repeated, it is demonstrated that there are smaller cells within the
smaller cells, a fact which amply testifies as to the magnification and
resolving power obtainable with the universal microscope.
More than 20,000 laboratory cultures of carcinoma were grown
and studied over a period of 7 years by Dr. Rife and his assistants
in what, at the time, appeared to be a fruitless effort to isolate the
filter-passing form, or virus, which Dr. Rife believed to be present in
this condition. Then, in 1932, the reactions in ‘growth of bacterial
cultures to light from the rare gasses was observed, indicating a new
approach to the problem. Accordingly, blocks of tissue one-half
centimeter square, taken from an unulcerated breast carcinoma, were
placed in triple-sterilized K Medium and these cultures incubated at
37° C. When no results were forthcoming, the culture tubes were
placed in a circular glass loop filled with argon gas to a pressure of
14 millimeters, and a current of 5,000 volts applied for 24 hours, after
which the tubes were placed in a 2-inch water vacuum and incubated
at 387° C. for 24 hours. Using a specially designed 1.12 dry lens, equal
in amplitude of magnification to the 2-mm. apochromatic oil-immer-
sion lens, the cultures were then examined under the universal micro-
scope, at a magnification of 10,000 diameters, where very much ani-
mated, purplish-red, filterable forms, measuring less than one-twen-
tieth of a micron in dimension, were observed. Carried through 14
transplants from K Medium to K Medium, this B. X. virus remained
constant; inoculated into 426 Albino rats, tumors “with all the true
pathology of neoplastic tissue” were developed. Experiments con-
ducted in the Rife Laboratories have established the fact that these
characteristic diplococci are found in the blood monocytes in 92 per-
cent of all cases of neoplastic diseases. It has also been demonstrated
that the virus of cancer, like the viruses of other diseases, can be easily
changed from one form to another by means of altering the media upon
which it is grown. With the first change in media, the B. X. virus
becomes considerably enlarged although its purplish-red color remains
unchanged. Observation of the organism with an ordinary microscope
is made possible by a second alteration of the media. A third change
is undergone upon asparagus base media where the B. X. virus is
transformed from its filterable state into cryptomyces pleomorphia
NEW MICROSCOPES—SEIDEL AND WINTER 215
fungi, these fungi being identical morphologically both macroscopi-
cally and microscopically to that of the orchid and of the mushroom.
And yet a fourth change may be said to take place when this crypto-
myces pleomorphia, permitted to stand as a stock culture for the period
of metastasis, becomes the well-known mahogany-colored Bacillus
coli.
It is Dr. Rife’s belief that all micro-organisms fall into 1 of not
more than 10 individual groups (Dr. Rosenow has stated that some of
the viruses belong to the group of the streptococcus), and that any
alteration of artificial media or slight metabolic variation in tissues
will induce an organism of one group to change over into any other
organism included in that same group, it being possible, incidentally,
to carry such changes in media or tissues to the point where the or-
ganisms fail to respond to standard laboratory methods of diagnosis.
These changes can be made to take place in as short a period of time
as 48 hours. For instance, by altering the media—4 parts per million
per volume—the pure culture of mahogany-colored Bacillus coli be-
comes the turquoise-blue Bacillus typhosus. Viruses or primordial
cells of organisms which would ordinarily require an 8-week incuba-
tion period to attain their filterable state, have been shown to produce
disease within 3 days’ time, proving Dr. Rife’s contention that the
incubation period of a micro-organism is really only a cycle of rever-
sion. He states:
In reality, it is not the bacteria themselves that produce the disease, but we
believe it is the chemical constituents of these micro-organisms enacting upon
the unbalanced cell metabolism of.the human body that in actuality produce the
disease. We also believe if the metabolism of the human body is perfectly bal-
anced or poised, it is susceptible to no disease.
In other words, the human body itself is chemical in nature, being
comprised of many chemical elements which provide the media upon
which the wealth of bacteria normally present in the human system
feed. These bacteria are able to reproduce. They, too, are composed
of chemicals. Therefore, if the media upon which they feed, in this
instance the chemicals or some portion of the chemicals of the human
body, become changed from the normal, it stands to reason that these
same bacteria, or at least certain numbers of them, will also undergo
a change chemically since they are now feeding upon media which
are not normal to them, perhaps being supplied with too much or too
little of what they need to maintain a normal existence. They change,
passing usually through several stages of growth, emerging finally as
some entirely new entity—as different morphologically as are the
caterpillar and the butterfly. (to use an illustration given us). The
majority of the viruses have been definitely revealed as living organ-
isms, foreign organisms it is true, but which once were normal inhab-
619830—45——15
216 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
itants of the human body—living entities of a chemical nature or
composition.
Under the universal microscope disease organisms such as those of
tuberculosis, cancer, sarcoma, streptococcus, typhoid, staphylococcus,
leprosy, hoof and mouth disease, and others may be observed to suc-
cumb when exposed to certain lethal frequencies, coordinated with the
particular frequencies peculiar to each individual organism, and di-
rected upon them by rays covering a wide range of waves. By means
of a camera attachment and a motion-picture camera not built into
the instrument, many “still” micrographs as well as hundreds of feet
of motion-picture film bear witness to the complete life cycles of
numerous organisms. It should be emphasized, perhaps, that invari-
ably the same organisms refract the same colors when stained by
means of the monochromatic beam of illumination on the universal
microscope, regardless of the media upon which they are grown. The
virus of the Bacillus typhosus is always a turquoise blue, the Bacillus
coli always mahogany colored, the Mycobacterium leprae always a
ruby shade, the filter-passing form or virus of tuberculosis always an
emerald green, the virus of cancer always a purplish red, and so on.
Thus, with the aid of this microscope, it is possible to reveal the
typhoid organism, for instance, in the blood of a suspected typhoid
patient 4 and 5 days before a Widal is positive. When it is desired
to observe the flagella of the typhoid organism, Hg salts are used
as the medium to see at a magnification of 10,000 diameters.
In the light of the amazing results obtainable with this universal
microscope and its smaller brother scopes, there can be no doubt of
the ability of these instruments to actually reveal any and all micro-
organisms according to their individual structure and chemical con-
stituents.
With the aid of its new eyes—the new microscopes, all of which are
continually being improved—science has at last penetrated beyond
the boundary of accepted theory and into the world of the viruses with
the result that we can look forward to discovering new treatments
and methods of combating the deadly organisms—for science does
not rest.
To Dr. Karl K. Darrow, Dr. John A. Kolmer, Dr. William P. Lang,
Dr. L. Marton, Dr. J. H. Renner, Dr. Royal R. Rife, Dr. Edward C.
Rosenow, Dr. Arthur W. Yale, and Dr. V. K. Zworykin, we wish to
express our appreciation for the help and information so kindly given
us and to express our gratitude, also, for the interest shown in this
effort of bringing to the attention of more of the medical profession
the possibilities offered by the new microscopes.

RADIO ACOUSTIC RANGING (R. A. R.)
By ComMMANDER K. T. ADAMS
United States Coast and Geodetic Survey
[With 1 plate]
Hydrographic surveying consists essentially in measuring water
depths from a survey vessel and locating those depths in geographic
position or with reference to the adjacent land features. The method
almost universally used for fixing hydrographic surveys within sight
of land is by measuring two sextant angles to three appropriately
located visible control stations. This is the well-known three-point
problem. In hydrographic surveying such a position determination
is called a three-point fix. The method is sometimes used beyond sight
of land, where the depths of the water permit, by utilizing systems of
anchored buoys for control stations.
Beyond the limit of visibility of shore objects and where buoys can-
not be used, hydrographic surveys were formerly controlled either
by dead reckoning or by celestial observations. At considerable dis-
tances from the coast and in deep oceanic areas, such methods sufficed,
even though both are notably inaccurate as compared with the three-
point fix method. However, there was serious need for a more accurate
method for use in coastal waters just beyond the range of the three-
point fix method. Radio acoustic ranging (R. A. R.) was developed
for use in such areas.
HISTORY OF R. A. R.
Subaqueous sound was first used in navigation to determine the
direction of an underwater sound source by means of two hydrophones
(subaqueous sound receivers) installed on a ship, one on each side near
the ship’s bow. A patent was granted for this device in 1894. Prob-
ably the first practical use of subaqueous sound to determine hori-
zontal distances at sea was by means of a submarine bell suspended
below a lightship. Such bells were in general use by the United
States Lighthouse Service in 1906. Other experiments were made in
connection with the use of subaqueous sound in navigation, but the
rapid development of radio direction finding fulfilled the need for
position determination in navigation. The sinking of the Titanic in
221
222 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
1912 emphasized the need for a means to detect icebergs in the track
of a vessel and led to experiments in the use of subaqueous sound for
this purpose. The instruments and methods developed, however, found
their greatest application in measuring depths of water by subaqueous
sound, resulting in modern echo sounding.
During World War I the transmission of sound in sea water was
intensively studied by the world’s foremost scientists in combatting
the submarine menace. As a result, instrumental equipment for trans-
mitting and receiving subaqueous sound was perfected, as well as
instruments specifically designed for the measurement of sound travel.
After World War I, the Coast and Geodetic Survey became interested
in the possible use of the method to control hydrographic surveys. In
collaboration with the War Department and the Bureau of Standards,
experiments were conducted in the further development of the method
and in the redesign of instrumental equipment. The method was first
actually used in hydrographic surveying on the ship Guide off the
coast of southern California in early 1924. It was an immediate
success, although many details of procedure had to be perfected before
it could be used with assurance.
THEORY
In radio acoustic ranging the position of a subaqueous sound source
is determined with reference to two or more appropriately located
sound receivers whose positions are known. Such a use of sound
has also been called “phonotelemetry.” Angles are not utilized in
this procedure—the unknown position is determined by measuring
the travel times of the sound from its source to the sound receivers.
If the effective horizontal velocity of sound in sea water is known, the
distances from the sound source to the receiving stations may be
determined by multiplying the travel times by the velocity, and
from the distances the position of the sound source may be found.
There are several ways in which the travel time of subaqueous
sound can be used to determine the position of an unknown point:
(a) Three or more appropriately located receiving units may be
interconnected electrically or by radio and the times of arrival of the
subaqueous sound at the several stations may be recorded at a central
station. Knowing the velocity of sound, the differences between the
arrival times may be used to derive the position of the source of the
sound. This is known as the “differential method” and it is in
general military use to determine the positions of enemy gun
emplacements.
(6) The subaqueous sound impulse may be synchronized at the
source with a radio signal. If the elapsed times between the receipt
of the radio signal and the receipt of the subaqueous sound are
RADIO ACOUSTIC RANGING—ADAMS 223
observed at two or more receiving stations at known positions, these
time intervals may be used to determine the position of the sound
source.
(c) All operations may be controlled and all measurements made
at the sound source. A subaqueous sound signal is made near a
survey vessel and its time recorded. The instants of arrival of the
subaqueous sound at two or more receiving stations are then signaled

Figure 1.—Radio acoustic ranging. In hydrographic surveying the ship’s position
is determined by subaqueous sound travel to sono-radio buoys anchored at
known positions. A, the bomber throws a small TNT bomb overboard from the
moving ship. B, the bomb explodes and the resulting sound wave travels
toward the sono-radio buoys (g and h) via paths (C—C) and toward the
hydrophone (e) in the bottom of the ship via the path (D—D). The sound
wave (F) travels in all directions at a velocity of about 1.5 km. per Sec.
Instantly on arrival at a sono-radio buoy (g) a radio signal (R) is transmitted
which is received at the ship. In the figure the sound wave has not yet arrived
at sono-radio buoy (h).
automatically by radio, and received and recorded on board the
survey ship. From these data, the elapsed time between the origin
of the sound and its receipt at each station is known and the position
of the survey ship may be determined.
This is the method used by the Coast and Geodetic Survey, and
is considered the most practicable for use in hydrographic surveying
because all operations are controlled from the survey ship and all
224 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
data are recorded thereon and become available to the hydrographer
in the shortest possible time. This method avoids errors made in
transmission, which are always possible where the data are received
elsewhere and radioed to the vessel.
R. A. R. OPERATION
To determine a position by R. A. R., the following data must be
known: The receiving stations (that is, the hydrophones) must be
established at known positions. The travel times of the subaqueous
sound from its origin to its receipt at each receiving station must
be measured with an accuracy of about 0.01 second. The effective
horizontal velocity of sound must be known. (The travel path of the
sound is not necessarily a straight line, as is explained later, but to
determine horizontal distances by R. A. R., it is obvious that the
velocity of sound that is required is the horizontal distance divided
by the travel time.)
A sheet with a projection is prepared on which the positions of the
receiving stations are plotted. The measured travel times are multi-
plied by the effective horizontal velocity of sound to obtain the hori-
zontal distances between the sound source and the receiving stations.
The position of the sound source is then at the intersection of the arcs
drawn from the stations with the computed distances as radii.
The following description illustrates briefly how R. A. R. is used by
the Coast and Geodetic Survey: A subaqueous sound is produced by
the explosion of a TNT (trinitrotoluene) bomb thrown overboard
from the survey ship while under way. A hydrophone (subaqueous
receiving unit) in the hull of the ship, and a radio receiver on the ship
are connected to a chronograph. The receiving station consists of a
submerged hydrophone connected to a radio transmitter which oper-
ates automatically when the hydrophone is actuated by a subaqueous
sound.
In addition to the ordinary survey personnel, certain specialists are
required in R. A. R. One officer is in direct charge of all operations;
he plots the ship’s positions as determined from the R. A. R. data.
A chronograph attendant is in charge of the chronograph and oversees
its functioning during the time from the bomb explosion to the receipt
of the radio signals. A radio technician is in charge of the instru-
mental equipment on the survey ship; he attends to the proper tuning
of the radio receiver and assists the chronograph attendant in identify-
ing the radio signals from the receiving stations. An explosives expert,
called a bomber, is in charge of the explosives and the preparation of
the bombs; he lights the bomb and throws it overboard when instructed
to do so by the chronograph attendant.
RADIO ACOUSTIC RANGING—ADAMS 225
One minute before an R. A. R. position is desired, an electric bell
signals the bomber to get a bomb ready. The bell signal also indicates
the size of bomb wanted. A detonator and fuse are inserted in the bomb
and the fuse is lighted a few seconds before the time for the position.
When the fuse is burning, the bomb is thrown overboard from the
ship’s quarter and a bell is rung as it strikes the water. This is the
official time of the position. (The time of the explosion, which comes
7 or 8 seconds later, is not the time of the position, because by that
time the ship is some little distance away from the place of the explo-
sion.) The electric bell is heard by the officer in charge and by the
chronograph attendant. The time and log are read and recorded and
a sounding is taken. Any changes in course or speed are made at this
time. At the sound of the bell, the chronograph attendant starts the
chronograph and connects it with the ship’s hydrophone. When the
bomb explodes, the sound is received through the hydrophone and reg-
isters automatically on the chronograph tape. After the explosion has
registered on the chronograph tape, the chronograph is switched from
the hydrophone to the ship’s radio receiver. The sound of the bomb
explosion travels through the water in every direction and eventually
reaches the several receiving stations. At the instant the sound arrives
at each receiving station hydrophone, the radio transmitter connected
to it automatically sends a radio signal, which is received on the ship’s
radio receiver and registers on the chronograph. During this time,
which may be from a few seconds to more than 100 seconds, a mark is
being made each second (or each tenth second) on the chronograph
tape. As the radio returns are registered, the chronograph attendant
identifies them, and when the last one has been received, the time
intervals, in seconds and hundredths of seconds, from the explosion to
its receipt at the several receiving stations are taken from the tape.
Each radio return and its corresponding distance must be correctly
identified with reference to the station from which it was received.
The time intervals are then reported by the chronograph attendant to
the officer in charge who determines from them the position of the sur-
vey ship at the time the bomb struck the water. This entire operation
takes on the average about 4 or 5 minutes.
R. A. R. RECEIVING STATIONS
Three different types of receiving stations have been used by the
Coast and Geodetic Survey. In their chronological development they
are: Shore station, ship station, and sono-radio buoy. Ship stations
are no longer used; shore stations are sometimes used; but sono-radio
buoys are used in most R. A. R. surveys.
Shore stations.—R. A. R. was first used by the Coast and Geodetic
Survey on the Pacific coast of the United States. Here comparatively
226 § ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
deep water generally extends reasonably close to the shore and, as is
now known, the temperature conditions of the water are favorable for
horizontal transmission of sound. Shore stations were used at this
time. A shore station consists of a conventional radio receiving and
transmitting station installed on shore, connected by electric cable with
a submerged hydrophone placed offshore in an appropriate depth of
water where it is not shielded by shoals. The hydrophone is attached
to an anchor, but is buoyed to float at a selected depth below the water
surface,
Each shore station is manned by one or more radio technicians. The
principal advantage of shore stations is that the radio technician can
keep the apparatus in repair, the batteries charged, and the station
operating at maximum efficiency at all times. Surf or other uncontrol-
lable conditions may actuate the hydrophone if it is too sensitive.
The radio technician can vary the sensitivity of the apparatus for the
best reception. He can also listen to the sound of the bomb explosion
when it is received and can measure its amplitude. A knowledge of the
strength of the received sound is valuable to the officer in charge in
weighting the results and in determining the size of bombs to use.
Shore stations are more expensive to establish and maintain than
sono-radio buoys, but their efficiency is greater. Laying the cable
from the hydrophone through the surf to the radio station is the most
difficult part of the establishment of a shore station, and sometimes
weather may prevent it for several weeks at a time. And unless the
area in the vicinity of the hydrophone has been thoroughly sounded,
one has no assurance that intervening shoals or irregular types of
bottom will not interfere with the receipt of the sound.
Ship stations—When R. A. R. was first used on the Atlantic coast
of the United States, it was soon found that shore stations would not
function satisfactorily. The Continental Shelf on this coast generally
extends many miles seaward, and the depths of water on it are com-
paratively shallow. Moreover, the temperature conditions of the water
are not so favorable for the transmission of sound as they are on the
Pacific coast. To overcome these difficulties, small ships were anchored
offshore at known positions and used as floating R. A. R. stations. The
receiving stations could then be placed in deeper water, thus shortening
the distance through which the sound had to travel. The shore appa-
ratus was placed on the ship, and the hydrophone was anchored, as at
a shore station, a short distance from the ship so that ship noises would
not interfere. These ship stations were then operated just as shore
stations. They had all the important advantages of shore stations and
in addition they were mobile. Their maintenance, however, was ex-
ceedingly costly, and as the ships were small, they frequently had to
RADIO ACOUSTIC RANGING—ADAMS 227
leave their stations in bad weather or be exposed to damage by storm.
Ship stations are no longer used by the Coast and Geodetic Survey.
Sono-radio buoys.—Soon after ship stations had been used success-
fully, the idea was conceived of using a buoy in which was housed a
fully automatic unit for receiving the sound impulse and transmitting
the radio signal—hence the name sono-radio buoy.
Two types of structures have been used for sono-radio buoys: One
type in which a steel drum is held in a wooden framework, and the
other a specially designed all-metal type. The latter requires more
special fittings and parts than the former, but both are about equally
successful. These buoys are constructed on the ship by the ship’s
personnel, using readily available materials.
From its long experience with the use of buoys as water signals, the
Coast and Geodetic Survey has evolved a more or less standard type
of wooden structure which has been used in the construction of sono-
radio buoys. Such a buoy consists of a 50-gallon steel drum with a
counterweight to hold it upright and a superstructure extending about
16 feet above the water, the batteries, the radio transmitter, and the
necessary electric circuits being placed in the drum. A vertical an-
tenna is supported on the superstructure and the hydrophone is sus-
pended from the counterweight at a depth of about 7 fathoms.
The electric apparatus in the sono-radio buoy was designed espe-
cially for automatic use in R. A. R. The principal parts of the equip-
ment are the audio amplifier, the keying circuit, the radio trans-
mitter, and the hydrophone. All parts must be especially constructed
and are generally made by the radio technicians on the survey ship.
The apparatus used in all sono-radio buoys is very similar, although
minor differences have been incorporated depending on the conditions
encountered. Sono-radio buoys can be used from 1 to 3 months with-
out attention.
The frequency of the sound of a bomb explosion is below 800 cycles.
The electric apparatus is designed to receive and amplify sounds in
this frequency range. The amplifier must be stable and any time lag
in it must be small and relatively constant. The purpose of the keying
circuit is to cause the radio transmitter to operate automatically when
the bomb signal actuates the hydrophone. It is designed so that un-
wanted sounds of comparatively low intensity will not operate the
radio transmitter, but that when the sound of a bomb is received the
transmitter operates instantly at nearly full power.
Extra circuits are sometimes incorporated in sono-radio buoys for
the purpose of shortening the transmitted radio signal. When radio
returns are being received from several sono-radio buoys, it is obvious
that an early, return which is prolonged unduly may blanket subse-
quent returns coming immediately afterward from other sono-radio
228 © ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
buoys. Due to reverberation, multiple reflections, and other causes, a
radio signal in such cases may be prolonged as much as 7 seconds.
Moreover, defects occurring in the electric circuits or unwanted noises
may tend to make a particular sono-radio buoy transmit almost con-
stantly. The so-called shortening circuit limits the length of radio
transmission to a half second or less, after which the sono-radio buoy
is rendered inactive for a period of 8 to 5 seconds. There are certain
disadvantages in using these circuits. When all the radio signals
transmitted are of equal length, signals caused by bombs cannot be
distinguished from other signals, as, for example, those caused by
water noises. Moreover, if a sono-radio buoy is actuated by an extra-
neous cause just before the bomb signal arrives, the silencing circuit
prevents the bomb signal from operating it. Shortening-and-silencing
circuits, therefore, are not used where prolonged signals are not par-
ticularly bothersome.
To obtain constancy of radio frequency, a quartz crystal is incorpo-
rated in the transmitter. Several radio frequencies between 2492 and
4160 kilocycles are authorized for use in sono-radio buoys, but those
most frequently used are 4135 and 4160 kilocycles. Using these latter
frequencies, the minimum radio frequency power required for satis-
factory results under normal operating conditions is about 3 watts,
although up to 26 watts has been used.
A hydrophone is a subaqueous sound-detecting device. It is used in
R. A. R. to receive the sound energy from a distant underwater bomb
explosion and to convert it to electric energy. Most hydrophones con-
sist of a watertight housing containing an electromagnetic, piezoelec-
tric, or other electroacoustic device, which is coupled to the housing in
such a way that the sound impinging on the housing, or on its dia-
phragm, is transmitted mechanically to the electroacoustic device,
which in turn converts this mechanical energy into electric energy.
As sound passes through an elastic medium, such as water, there is
an alternate condensation and rarefaction of the medium at a given
point, resulting in a corresponding increase and decrease of the pres-
sure at this point. In addition, at any point the particles of the me-
dium undergo regional displacement forward and backward along the
direction of sound propagation. Hydrophones are operated by this
pressure variation and particle displacement. Several different types
of hydrophones have been designed especially for use in R. A. R. The
hydrophone itself does not have to be extremely sensitive, but the
hydrophone and the audio amplifier must be designed so that together
they will have the required sensitivity. A hydrophone must respond
well to the frequency of a sound caused by a subaqueous explosion.
The hydrophone must not be directive to a marked degree, for in hy-
drographic surveying the sound which is to actuate it may come from
emee et a
Se eee

almost any direction. The hydrophone or the case in which it is housed
must be watertight. The most frequent cause of hydrophone failure is
leakage. A hydrophone becomes inoperative if the armature of the
electromagnetic unit is forced against one of the pole pieces and held
there. This may result if a bomb explodes too close to the hydrophone
or if anything strikes the hydrophone while the sono-radio buoy is
being placed on its station.
Before a sono-radio buoy is put on station, the gain of its audio
amplifier must be adjusted for sensitivity. If the gain is too low, the
unit will be insensitive and returns will not be received from bomb
explosions more than a short distance away. If the gain is too high,
the unit will be actuated by the action of the waves, nearby water
noises, or by the movement of the buoy itself. In the latter case, the
buoy transmits continuously, and the receipt of a bomb explosion
cannot be detected. Furthermore, the continuous radio signals inter-
fere with the receipt of signals from other sono-radio buoys which are
operating satisfactorily. It is obvious that a sono-radio buoy placed
on station to operate automatically for several weeks at a time must not
be adjusted for operation in perfect conditions, for then survey opera-
tions would often be interrupted by weather conditions. This explains
one of the principal advantages of a shore station. The latter being
attended, its sensitivity can be adjusted at all times for best operation.
Abnormal performance of a sono-radio buoy is usually disclosed in
one of two ways—either it is too insensitive to bomb explosions or there
is an excess of stray signals.
SHIP EQUIPMENT
The special equipment used on the survey ship for R. A. R. is com-
paratively simple and easily understood. It consists of a hydrophone
in the ship’s bottom, a radio receiver, a chronograph and amplifier, and
a break-circuit chronometer. Except for the chronograph amplifier,
standard commercial products are used in each case. Their coordinate
functions from the time a bomb explodes until the radio signals from
the R. A. R. stations have been recorded on the chronograph are as
follows:
The bomb explosion is received on the hydrophone, after which the
signal is amplified sufficiently to operate the stylus of a chronograph
which makes a mark on a moving tape. The stylus circuit is then
immediately connected to the radio receiver. Signals from the R. A. R.
stations are received and marked on the tape by the same stylus.
Another stylus operated from a break-circuit chronometer marks regu-
lar time intervals on the tape during this entire period. Then the time
intervals from the explosion of the bomb to the reception of the radio
signals may be measured on the tape.
230 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
The hydrophone, through which the sound of the bomb explosion is
received, is installed in a water-filled tank which is fastened to the
inner side of the hull of the ship. It must be located where ship noises
will affect it least.
Any good commercial communication radio receiver may be used so
long as it will cover the necessary range of frequencies.
The chronograph amplifier is especially built by the ship’s radio
technicians. Its purpose is to amplify the impulse from the hydro-

The bomb explosion is registered on a paper tape at G. The sound wave of the

receiver. The amplification must be sufficient to actuate the stylus in
the chronograph.
A chronograph is a graphic-recording time-measuring device. It is
connected to a break-circuit chronometer, which provides the time
record. A narrow wax-coated paper runs through the chronograph
beneath two sharp styluses electromagnetically operated. The tape
moves at the rate of about 2 centimeters a second. One stylus is con-

nected with the chronometer and makes a mark on the tape once a
second. Another stylus is connected with the chronograph amplifier
and is actuated by the reception of the bomb signal and later by the
reception of the radio signals. This record permits the scaling of the
time intervals to the nearest 0.01 second by interpolation.
A different instrument, called the Dorsey chronograph, designed
and built by the Coast and Geodetic Survey, is also used for the same
purpose. It incorporates electric time measurement, starting with a
piezoelectric crystal, and provides much more constant and correct
time than a break-circuit chronometer. The tape in this chronograph
runs at a speed of about 5 centimeters a second, and a mark is made each
tenth second and the seconds are numbered. The instrument is also
automatic in that the electric bell signal signifying that the bomb has
struck the water starts the tape moving and the timing stylus begins
marking tenth seconds. When the hydrophone is actuated by the
bomb explosion, the next tenth second is marked zero and the mark at
each subsequent second is numbered. Time intervals to the nearest
0.01 second can be interpolated from this record by eye.
BOMBS
For use in R, A. R. a sound of great intensity reaching a peak almost
instantly and one that will travel through the water in all directions is
required. The explosion of a trinitrotoluene (TNT) bomb has been
found best adapted for the purpose, although any type of explosive
suitable for use under water can be used. Dynamite has been used, but
it is more unstable and more dangerous to handle than TNT. The
frequency of a bomb explosion is below 300 cycles, which is lower than
most interfering noises.
The TNT itself does not have to be in a watertight container. For
best results the container should be made of a comparatively strong
rigid material so that the gases generated are contained until detona-
tion is complete, whereupon the container bursts. The resulting ex-
plosion produces a highly compressed sound wave that has a greater
range than one from an explosion in a comparatively fragile container.
For long distances and best results, hollow cast-iron spheres with
half-inch walls, containing from 1 to 4 pounds of TNT, are used.
These spheres have to be especially cast and are expensive and heavy
to handle. For ordinary distances and for perhaps 95 percent of the
cases, ordinary commercial tin cans with a friction top are used.
Three sizes of the latter are commonly used, 14, 14, and 1 pint, depend-
ing on the distances involved and the characteristics of the area being
surveyed.
Ordinary commercial detonators made of fulminate of mercury are
used with standard waterproof fuse to detonate the TNT. Tin cans
619830—45—16
232 § ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
of various sizes are filled in advance with TNT compacted firmly. A
hole is punched in the center of the lid of each can. Fuses of various
lengths are attached to the detonators and this junction of the fuse
and detonator must be watertight. Just before an R. A. R. position is
required, the detonator is inserted through the hole in the lid of the
can and pushed down into the TNT. The fuse is lighted on an electric
heating element and the bomb is thrown overboard well clear of the
ship, which is under way.
The bombs must not be exploded too close to the survey ship. Also
they should not explode too close to the surface of the water, for then
part of the sound energy is dissipated into the air. Best results are
apparently obtained with explosions at a depth of about 7 fathoms.
To achieve these two results, the bombs are weighted to make them
sink at the required speed, and the fuse is cut in lengths to provide the
required delay in time.
In 1940 the cost of a 1-pint bomb with fuse and detonator was about
30 cents.
VELOCITY OF SOUND IN SHA WATER
To measure distances by subaqueous sound transmission, one needs
to know not only the elapsed time intervals but the effective horizontal
velocity at which the sound travels through the water. The velocity
of propagation of sound in sea water may be calculated from the tem-
perature and salinity of the water and the hydrostatic pressure.
Tables have been prepared based on these three variables. The velocity
of sound varies with these three characteristics by the following ap-
proximate percentages:
(a) Each 1° C. increase in temperature increases the velocity 0.2
percent.
(b) Each 1 part per 1,000 increase in salinity increases the velocity
0.1 percent.
(c) Each additional 100 fathoms (183 m.) of depth increases the
velocity 0.22 percent. The velocity of sound in water is approximately
1,500 meters per second at a temperature of 14° C., salinity 35 parts
per 1,000, and at surface atmospheric pressure. ‘
To determine the velocity of sound from the tables, the temperature
and salinity of the water must be measured, and the depth must be
known, for pressure varies almost exactly with depth. The variation
of salinity in sea water is small, and its effect on velocity, as compared
with the effect of variation in temperature, is relatively unimportant.
The temperature varies not only from place to place, but ordinarily
decreases with the depth. For the average R. A. R. survey, the velocity
of sound must be known within 4 meters per second, and to attain this
RADIO ACOUSTIC RANGING—ADAMS 233
accuracy the average temperature of the water through which the
sound wave passes must be known within approximately 1° C.
During a hydrographic survey controlled by R. A. R., frequent tem-
perature observations are made. Observations from the surface to
the bottom are made at various places and times, supplemented by
more frequent observations at the surface and the bottom. Tempera-
tures are measured with one or more reversing thermometers attached
to a sounding wire and lowered to the desired depth. The thermome-
ter reverses as soon as it starts upward and breaks the column of mer-
cury so that the value registered at the greatest depth can be read
after the thermometer has been brought to the surface.
A bathythermograph, a comparatively new instrument, is also used
to measure water temperatures in the upper 75 fathoms, where the
greatest variation occurs. This instrument records automatically and
graphically the temperatures with reference to depths.
The variation in salinity normally encountered affects velocities of
sound only slightly as compared with temperature, but salinity does
vary and its value must be determined. In the Coast and Geodetic
Survey the salinity is determined indirectly by measuring with a
hydrometer the specific gravity of a water sample. An accuracy of
about one-tenth part per 1,000 may thus be obtained.
Velocity of sound as determined from the physical characteristics of
the water and from tables is obviously the velocity of propagation of
the sound wave, irrespective of direction. The effective horizontal
velocity is required in R. A. R. If the sound wave is refracted, or is
reflected from the bottom one or more times en route to the receiving
station, as is explained later, it is apparent that the theoretical velocity
alone will not suffice for use in R. A. R. In such cases, the measured
time intervals are greater than they would be if the sound traveled
by a direct horizontal path.
Under certain conditions the effective horizontal velocity of sound
at a place can be determined experimentally. If a bomb is exploded
at a known horizontal distance from a receiving station and the time
interval from the explosion to its receipt at the receiving station is
measured, the distance divided by the time interval will give the effec-
tive horizontal velocity of sound between the source and the receiver
for the temperature and salinity of the water at that place and time,
irrespective of the path of the sound wave. Where the depths of water
permit, it is customary to make such tests throughout an area being
surveyed and at intervals during the survey. For a survey in uniform
depths where the temperature and salinity are relatively constant,
results of such tests can be subsequently used in determining R. A. R.
positions. Where the temperature and salinity change frequently,
the velocity of sound determined by tests can be modified to take into
234 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
account the temperature and salinity differences. But where the
depths in the area vary to a marked degree, and especially where the
depths are too great to permit tests to be made, the velocity of sound
values must be determined from an assumption of the path of the
sound wave.
There is also an indirect method for determining the effective hori-
zontal velocity of sound under certain conditions and allowing certain
assumptions. If the time intervals from a bomb explosion to three
receiving stations at known positions are measured accurately, and
the same temperature and salinity conditions and depths along the
three paths of sound are assumed, then the effective horizontal velocity
can be computed by means of a rather involved formula. It is obvious
that there must be no doubt regarding the accuracy of the travel times.
If one value is doubtful or if the conditions along the three paths are
dissimilar, an erroneous value of the velocity of sound will result.
PATH OF A SOUND WAVE
In an ideal water medium with uniform characteristics and unlim-
ited dimensions in every direction, a sound from a nondirectional
source would be propagated along straight paths in every direction.
The arrival time at any receiving station would be the time required
for the sound to travel the shortest path. In such a case, the theoreti-
cal velocity of sound would be the same as the effective velocity, and
R. A. R. would not be complicated by uncertainties due to the path of
the sound wave.
Unfortunately, the ideal medium does not exist in practice, and the
propagation of sound in water is indeed complicated. The sound wave
is propagated through a body of water bounded above by the water
surface and below by the ocean bottom; the horizontal dimension of
the medium is long as compared with its vertical dimension; sound
waves are reflected from both boundaries of the medium, and within
the medium they are refracted by changes in the velocity of sound
along the path. These facts complicate the path of the sound wave.
The reception of sound is also complicated by the fact that the vari-
ous reflected and refracted waves interfere with one another. Where
two sound waves of the same frequency and wave form meet at one
point, they will tend to reinforce or neutralize each other, depending
on their directions of propagation and whether they meet in the same
or opposite phases.
It is apparent that, in a bounded water medium, the sound wave
may travel an almost unlimited number of paths. There will be one
direct path from the source to the receiver and a multitude of reflected
paths. The sound wave that first arrives at the receiver with sufficient
EEO
RADIO ACOUSTIC RANGING—ADAMS 235
intensity to actuate it is, of course, the one that is used in R. A. R.-—
other sound waves arriving later serve only to prolong the received
signal. Unfortunately, the sound traveling via the direct path is
almost always canceled by the sound wave reflected from the surface
of the water. This surface-reflected sound wave is reversed in phase,
and as the length of its path is nearly equal to the direct path, almost
complete cancelation of the two takes place. In actual experience the
sound via the direct path is rarely received at distances greater than
7 or 8 miles.
The result of this is that the useful sound wave in R. A. R. is the
one that is reflected at least once from the ocean bottom and, depending
on the depth of the water and its physical characteristics, the sound
may arrive at the receiving station after having been refletced a num-
ber of times between surface and bottom.
Another complication is the fact that the surface boundary is hori-
zontal, but the ocean bottom is not. A sound wave is reflected from a
boundary in the same way as a ray of light is reflected from a mirror,
the angle of reflection being always equal to the angle of incidence. If
the water is deep at the bomb explosion but the receiving station is
located in comparatively shallow water, as is the usual case in R. A. R.,
it is obvious that the bottom slopes upward along the effective path of
propagation. In such a case, each time the sound wave is refiected
from the bottom, its direction of propagation is changed toward the
vertical, and if enough reflections are involved and the slope of the
bottom is sufficiently great, the successive angles of reflection may be
decreased until the sound wave is reflected vertically upward or it may
actually reverse its horizontal direction of propagation, and never
reach the receiving station. This condition is aggravated in shoal
water where more reflections take place in a given horizontal distance
than do in deep water of the same characteristics. This partly explains
the difficulty encountered in sound transmission from deep water on
the Continental Slope to shoal water on the Continental Shelf. It also
explains the difficulty encountered in R. A. R. where there are inter-
vening shoal areas between the bomb explosions and the receiving
stations.
The path of a sound wave is also affected by refraction. Wherever
a change in the velocity of sound takes place along the path, the sound
wave is refracted. If pressure were the only characteristic affecting
velocity of sound, its constant increase with depth would cause a con-
stant increase in velocity, and the sound wave would be refracted in
the arc of a circle concave upward. It is rare, however, that pressure
is the only variable involved. The temperature of the water varies
and normally decreases with depth more than enough to overcome the
increase caused by pressure, until the depths become comparatively
236 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
great. This decrease in temperature causes a decrease in velocity
which refracts the sound wave downward.
Thus it is seen that for any given case in R. A. R. the path along
which the received sound has traveled may be very complicated. It
may have been reflected a number of times from the bottom and the
surface, and between these reflections it may have been refracted, either
upward or downward, or perhaps in both directions at different depths.
The excellent results obtained in R. A. R. are due to the fact that
water is a relatively good medium for the propagation of sound, even
though its physical characteristics, and consequently the velocity of
sound, vary with time, place, and depth. It is due also to the good
reflecting qualities of the water surface and the ocean bottom. The
sound is confined vertically and is reflected and amplified, somewhat
as it is in a speaking tube. Little of the energy of the sound wave is
actually lost:in reflections, although when the sea is rough or the ocean
bottom irregular, some of the sound energy may be dissipated.
R. A. R. IN PRACTICE
Subaqueous sounds have been detected with instruments of only
ordinary sensitivity at a distance of 400 nautical miles (740 km.). A
sound propagated vertically downward by an electromagnetic oscilla-
tor in a depth of about 200 fathoms (365 m.) has been heard after
having been reflected 23 times alternately from the bottom and the
surface. In R. A. R. the longest distance that has been measured is
184 nautical miles (340 km.). This was in connection with a test
which was concluded at that distance, but there was no observable
diminution in the intensity of the received sound as compared with
that received at somewhat lesser distances. In actual hydrographic
surveying, distances of 100 miles (185 km.) or more have often been
measured. Shore stations are much more efficient in this respect than
sono-radio buoys, although returns have been received from sono-radio
buoys at distances of 100 miles (185 km.). The type of area in which
sono-radio buoys are preferred to shore stations ordinarily limits their
range to about 30 or 35 miles (55 or 65 km.).
The operation of R. A. R. to control hydrographic surveys is now a
routine procedure. The position of the survey ship is fixed regularly
by R. A. R. at intervals of 10 minutes or less with as much casualness
as if three-point sextant fixes were being used.
The positions of the receiving stations are plotted on a projection,
just as the positions of triangulation stations are. Because of the long
distances ordinarily involved, the distortion which occurs in a plotting
sheet made of even the best drawing paper has considerable effect.
For this reason, a number of uniformly spaced concentric circles are
RADIO ACOUSTIC RANGING—ADAMS 237
drawn on the sheet from each R. A. R. station at the time the projection
is made.
The position of the survey ship can be plotted with a beam compass,
by swinging distance or time arcs from the respective receiving sta-
tions, but setting the beam compass with reference to the nearest of
Figure 3.—An area surveyed in 1939 by radio acoustic ranging (R. A. R.), showing
the sono-radio buoys and ordinary buoys used to control the hydrography. The
lines of buoys were located by taut-wire traverses, but some of the outer-
most sono-radio buoys were located by R. A. R. distances. Legend: @ ordi-

the concentric circles. The position of the ship is at the intersection of
the arcs. Positions can also be plotted by using a special circular
celluloid protractor.
R. A. R. was originally adopted to control hydrographic surveys be-
yond the visibility of shore signals or where survey buoys could not be
used. Since its use, however, does not depend on visual observation,
238 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
it is equally usable at night, or in fog. Survey ships of the Coast and
Geodetic Survey, using R. A. R., have surveyed continuously 24 hours
a day for periods of 10 days at a time.
Some statistics of a survey controlled exclusively by R. A. R. may
be of interest. They are from an offshore survey in the vicinity of
Nantucket Shoals off the northeast Atlantic coast of the United States.
These surveys were plotted on one 1:60,000 scale sheet and two
1: 120,000 scale sheets. Sono-radio buoys were used for receiving
stations at 24 different locations. The surveying was done between
May 2 and September 25, 1939. The area surveyed was 8,562 square
statute miles (22,176 sq. km.), and the total length of sounding lines
was 10,496 statute miles (16,892 km.) ; 5,506 bombs of various sizes
were used, made from 3,511 pounds of TNT and 4,170 feet of fuse. To
obtain the required temperature and salinity data, serial temperatures
were observed at 135 different places. The positions of the sono-radio
buoys were determined by taut-wire traverses, in connection with
which ordinary buoys were used at 60 different locations, in addition
to the sono-radio buoys. The total number of working days was 101,
including 18 days used for placing or picking up buoys and running
the taut-wire traverses for their locations. The survey vessel ran a
total distance of 16,481 nautical miles (30,543 km.) for all purposes
during the survey.

THE DAVID W. TAYLOR MODEL BASIN?
By Rear ADMIRAL HERBERT 8S. HOWARD, U. S. N.
Director, David W. Taylor Model Basin
[With 4 plates]
The largest and most completely equipped ship-model testing and
experimental plant in the world operates directly under the Bureau of
Ships of the Navy Department.
This plant, the David W. Taylor Model Basin, staffed by a highly
trained and capable group of officers and civilian technical and shop
personnel, has as its basic function the solving of problems concerning
the design and operation of naval vessels by testing models in water
under controlled conditions. Included in its work are the determina-
tion of the speed and powering of ships, launching, stability, action in
waves, turning and maneuvering, and propeller design. Besides ques-
tions of pure ship design and form, the problems presented for solution
cover the field of mine-sweeping devices, paravanes, and torpedoes; in
fact, everything which has to do with forms which move through the
water.
In addition to the preceding problems, special problems of struc-
tural design of ships comprise a major activity of the plant. These
problems cover all manner of special questions relating to the strength
of ships and their parts, the resistance of ship structures to underwater
explosions, structural vibration, and the effect of shock, and the elimi-
nation of such vibration and shock effects.
In general, the chief function of this organization at present is to
give the earliest possible solutions or answers to the wartime problems
submitted to it. Research, which has been and is being continuously
carried on, gives the background of knowledge which makes it possible
to undertake and furnish the solution to these urgent problems.
Although the Model Basin operates directly under the Bureau of
Ships, work is carried on not only for that Bureau but for all branches
of the Navy Department, whether for the Commander in Chief him-
self or any of the technical bureaus. Work is also done for other
branches of the Government, notably the United States Maritime

Commission, and for private companies and individuals, this practice
fulfilling the requirements of the act which created the establishment.
The construction of the Taylor Model Basin was authorized by Act
of Congress of May 6, 1936. This act gave authority for the purchase
of a suitable site and the construction of a new model basin establish-
ment for the United States Navy. This was to replace and extend the
work of the original Experimental Model Basin which had been in
service at the Washington Navy Yard for nearly 40 years. The old
experimental basin had become too small to carry out its work for the
Navy and private individuals, and its equipment was, moreover, be-
coming obsolete.
To commemorate the work of that officer who had been responsible
for the original Experimental Model Basin and under whom that basin
had operated for the greater part of its existence, the Secretary of the
Navy directed that the new establishment be known as “The David W.
Taylor Model Basin” in honor of Rear Admiral David Watson Taylor,
Construction Corps, United States Navy, Retired, former Chief Con-
structor of the Navy.
The location chosen for the new establishment was in the valley of
the Potomac some 12 miles from the center of Washington. This site
was selected not only because land was available but principally be-
cause three basic requirements were fulfilled. First, solid rock was
at the surface in this location; this meant that the foundations for the
rails of the towing carriages of the basins could be carried down to
solid rock and the extremely accurate alignment needed could be prac-
tically guaranteed. Second, an ample supply of clean fresh water
necessary for the testing basins was available, since the main conduits
to Washington were close at hand. Finally, the location was away
from heavy traffic which might disturb the alignment of the towing-
carriage rails and their foundations, but it was still fairly close to the
Navy Department which permitted easy communication and frequent
visits.
The new establishment was planned and laid out by Capt. H. E.
Saunders, who had been stationed at the old Experimental Model
Basin for a number of years. Based on long experience there and
reports from model basins the world over, the new model basin was
planned to provide not only the best and most up-to-date facilities and
equipment for model testing, but in such size and capacity as to ensure,
as far as could be foreseen, that it would meet all needs of the Navy for
many years to come.
The actual design was undertaken in 1933-34 by the Bureau of
Yards and Docks of the Navy Department and construction was
started in September 1937. The basins were filled with water in March
1939 and the plant was completed in July of that year. Because of the
TAYLOR MODEL BASIN—HOWARD 241
long time required for laying the carriage tracks and for making other
preparations, the principal activities were not transferred from the
Navy Yard until November 1940.
The original conception of this establishment, as indicated by the
authorizing act, was that it should be constructed to investigate and
determine the most suitable and desirable shapes and forms for naval
vessels and to investigate other problems of ship design. Thus
primarily the establishment was designed and equipped to carry out
experimental work on the forms of ships’ hulls and to estimate the
power required to drive them, with a secondary interest in other fea-
tures of design. This original conception has almost been lost sight
of in an expansion and growth far beyond the fields originally con-
templated. The war has naturally been principally responsible for
this great expansion. Under the heading of “underwater forms and
propulsion” the work has expanded until it has come to cover the
proper form or shape of almost any body which is propelled, towed, or
projected on or through the water; while under the secondary heading
of “other problems of ship design” the expansion has been so broad in
the fields of structural strength, shock, vibration, underwater explo-
sions and related subjects that the primary and secondary objects of
the original establishment have almost changed places.
The outstanding features of the Taylor Model Basin are its test
facilities, which are unusual both as to types and as to size and capacity.
For an understanding of the work undertaken a general description of
the physical plant and these facilities is necessary.
As a testing establishment the Taylor Model Basin was made large
enough to house equipment which would accomplish each of the vari-
ous types of research on models with the greatest degree of accuracy
and reliability.
Physically the establishment consists of three buildings: a main
building 871 feet by 54 feet; lying parallel to it, a basin building 1,330
feet long; and a wind-tunnel building. The main building houses in
its central section the offices, drafting and computing rooms, record
storage vaults, a library, a photographic laboratory, and a museum.
The western section of the building contains the shops where wood
and metal models, mechanical devices, instruments, dynamometers,
and other special equipment are made.
The eastern end of the main building constitutes the laboratory.
In this laboratory are located the 12-inch and 24-inch variable-pressure
water tunnels, 30,000-pound and 600,000-pound universal static-load
testing machines, and a 150,000-pound alternating-load testing ma-
chine, and other equipment.
The basin building is unique in its appearance, because of its barrel-
arch roof 1,188 feet long. Instead of a single large model basin like
242 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
the old one at the Washington Navy Yard, there are four separate
model basins each designed for a particular line of work.
The principal large deep-water basin is 963 feet long by 51 feet wide
by 22 feet deep. Here models of large ships are towed or self-
propelled. This is the largest basin of its kind in the world.
Joining the large basin is a shorter shallow-water basin 303 feet long
by 51 feet wide by 10 feet deep. The depth can be varied at will to rep-
resent rivers, canals, and channels of limited depth and width. In
this basin models of tugboats, barges, river craft, and other types of
shallow-water vessels are tested.
Forming a continuation of the west end of the shallow-water basin
is a J-shaped turning basin, for testing the maneuvering and steering
characteristics of models. In a special enclosure over this basin,
accurate photographic observations of the models under test are made
with a group of cameras about 40 feet overhead.
To the north side of the large basin there is a high-speed basin 1,168
feet long by 21 feet wide by 10 feet deep, for the testing of models of
high-speed motor boats and seaplane hulls. Incidentally, the site is
large enough to permit the extension of this basin to more than twice
its present length to meet requirements of the future.
In the basement of the main building is a small basin, 142 feet long
by 10 feet wide by 514 feet deep, for the testing of special models and
for unusual research problems.
The towing carriages, which span the basins and operate on the
precision-laid rails atop the basin walls, furnish the means of testing
the models. The heart of a towing carriage is the dynamometer,
which with its related recording instruments measures the forces
arising from the motion of a model through the water.
Two carriages are now in operation—carriage 1 over the deep-water
basin, and a special quiet-running carriage with wood frame and pneu-
matic-tire wheels over the high-speed basin. Under construction, and
to be placed in service during 1944, are carriages for the shallow-water
basin and the high-speed basin. The last carriage will have a top
speed of 24 knots.
The carriage which now operates on the deep-water basin is typical.
The specifications it must fill are exacting: a testing speed range of
from 0.1 to 18 knots, the selected speed to be constant during an
8-second measuring run within 0.01 knot, a rigid-frame structure to
span the 51-foot distance between the basin walls without permitting
disturbing vibrations or deflections at the midspan where the measur-
ing instruments are located, absolutely straight-line motion of the
towing point where the model is attached to the carriage, a dynamome-
ter to measure the model resistance during the measuring run to within
TAYLOR MODEL BASIN—HOWARD 243
0.01 pound but rugged enough to handle the forces on large, 30-foot
battleship models at full test speed.
Two variable-pressure water tunnels, designed primarily for testing
model propellers but also used extensively for special hydrodynamic
tests, are among the unusual facilities. Each water tunnel consists of a
closed duct circuit arranged in a vertical plane, in which water is
circulated at a known speed. In the lower limb of the apparatus is a
motor-driven impeller which circulates the water, and in the upper
limb is the test section, fitted with glass ports for visual and photo-
graphic observation of the propeller being tested in a jet of water of
uniform velocity and turbulence. The diameter of the jet nozzle is
12 inches for one of the water tunnels, and 24 inches for the other.
The model propeller is mounted on a motor-driven shaft projecting
into the test chamber. The thrust and torque of the propeller at vari-
ous speeds of revolution are measured by a dynamometer. Water
speeds in the 24-inch tunnel up to 35 knots are available.
Vacuum pumps lower the air pressure above the water in the test
chamber of the tunnel, in order to create an absolute pressure on the
model propeller corresponding to the combined effect of atmospheric
and water pressure on the propeller of the full-sized ship. Under these
conditions, the phenomena of cavitation occur on the model propeller
so that the test accurately represents the behavior of the full-scale
propeller. Cavitation is the formation of water-vapor cavities, or
“bubbles,” on the propeller blade surface, caused by high loading and
consequent serious reduction of pressure on the back, or “suction side”
of the propeller. Efficiency suffers when cavitation occurs. Cavita-
tion effects are studied by means of stroboscopic illumination of the
propeller being tested, and these effects are recorded by high-speed
flash photographs, of 1/30,000-second exposure.
In the laboratory building there are located two large machines for
testing structural specimens, both full-size and model scale. One, the
150,000-pound alternating-load testing machine, tests beams, columns,
riveted and welded joints, and other structural members in alternate
compression and tension over long periods of time, to discover the
manner, loading, and number of cycles to failure in fatigue.
The other large testing machine is a universal static-load testing
machine with 600,000-pound capacity in either tension or compression.
Stress-strain data, yield point, and ultimate strength of a wide variety
of structural specimens may be obtained with this apparatus.
One of the most unusual and recently completed facilities is the test
pond for underwater explosion tests. This is a pentagonal pond, dug
partly out of the solid rock and partly formed by built-up rock em-
bankments. It is roughly 150 feet across and will carry water to a
244 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
depth of 25 feet. In this pond research investigations of underwater .
explosions and explosive tests against models of ship structures are
carried out.
Information can be obtained on the trajectories of model bombs and
torpedoes after impact with the water surface by experiments made in
the new transparent-wali tank, using high-speed motion pictures to
record the paths of the models. The new tank has glass windows
forming one side and one end; it is 25 feet long, 9 feet deep, and 414
feet wide, filled with continuously filtered, crystal-clear water to insure
clear photographs. The windows are three-quarters of an inch
thick “tempered” glass, four times as strong as ordinary plate glass
of the same thickness. Intense photographic illumination is necessary
to obtain good film records of the objects moving through the water.
The circulating-water channel, now nearing completion, is an
unusual hydraulic testing facility, both as to type and size. Essen-
tially it consists of an open-top test section 22 feet wide and 60 feet
long in which a stream of water 9 feet deep flows at a maximum speed
of 10 knots. The object under test will be held stationary in the moving
stream and the forces exerted by the water measured by suitable dyna-
mometers. The walls and bottom of this channel contain windows
approximately 4 feet by 114 feet through which both visual and photo-
graphic observations can be made.
The chief advantages obtained by testing in the circulating-water
channel are that the object undergoing test can be viewed and photo-
graphed from all sides and that the tests may be carried on for an
indefinite period without stopping as at the end of a straight towing
run.
The objects tested in this channel will consist of ship models, torpedo
shapes, mines, and special devices which cannot be tested as well by
towing in still water. The water channel will complement the existing
turning basins and water tunnels but will not supplant them.
In order that such a large stream of water may be circulated at con-
stant speed with uniform flow throughout the test section, a structure
about 150 feet long and 45 feet high is required. The water is pumped
through the channel by two 1214-foot-diameter propeller-type pumps
driven by direct-connected 1,250-horsepower electric motors. These
motors rotate at constant speed and the rate of flow of the water is
regulated by adjusting the pitch of the propeller blades while running.
The wind-tunnel building is located to the west of the main building.
It contains two steel wind tunnels, each with a closed rectangular test
section 8 feet by 10 feet, and with single return passage. These tunnels
are equipped with 4-bladed, 16-foot-diameter wooden propellers, one
driven by a 1,000-horsepower motor, the other by a 700-horsepower
motor. These motors are controlled by the Clymer system which per-
TAYLOR MODEL BASIN—HOWARD 245
mits speed control within plus or minus ¥% percent. Air velocities can
be varied from approximately 10 to 220 miles per hour. Six precision
scales automatically record the three moments and three forces on the
model. A seventh scale records the wind velocity.
Airplane models up to 8-feet wing span can be tested both for normal
performance characteristics and for stability in yaw; two separate
systems for supporting the model are used for these two types of test.

ECURITY Ano
At the present time tests for the Bureau of Aeronautics are still
carried on principally in the old wind tunnels at the Washington Navy
Yard, but within a short time the new tunnels will be actively
operating.
The organization of the Taylor Model Basin is shown on the chart.
Rear Admiral Herbert S. Howard, U.S. N., is director; Capt. Harold
E. Saunders, U. S. N., who laid out the establishment and was in
246 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
charge of the entire work of preparing the facilities for operation,
is technical director and head of the technical division; and Capt.
W. C. Mehaffey, U.S. N. R., is executive officer and production officer.
The heart of the organization and the reason for its existence
rest in the technical division. This division is divided further into
three main divisions: hydromechanics, structural mechanics, and
aeromechanics.
Each of these divisions is headed by a senior officer, with officer
assistants, specially trained and qualified for this particular work.
The civil technical staff is of the same high caliber, the nucleus of this
staff possessing a national and international reputation in this highly
specialized work.
In the hydromechanics division the principal work falls within the
field of ships’ lines, propellers, and underwater forms such as mine-
sweeping gear and torpedoes. After the technical design of a device
is completed, a model is built to scale, in order to carry out the test
necessary to check the form and to determine the power needed to
propel or tow it; the test is made in one of the various model basins.
The procedure in a typical test of a ship is as follows.
The usual ship model is about 20 feet long, hollow, and fashioned
from layers of wood glued together. It is carefully shaped to represent
the outer surface of the ship’s hull, to exact scale, from keel to deck.
The model is complete as to its underwater form, with rudder, propel-
- lers, shafts, struts, bilge and docking keels, but without upper works.
The model is first towed, non-self-propelled, over one of the main
basins by the carriage which has already been described.
In making a towing run the carriage starts from rest, and smoothly
and gradually acquires the speed necessary for the test. When the
carriage is towing the model at a uniform rate at the desired speed,
and the model is producing its characteristic wave formation, the
actual resistance of the ship model in pounds and hundredths of a
pound is measured.
Later a second, self-propelled test is run, in which the model is
driven under its own power along the basin with small model propel-
lers. Small electric motors installed in the model, one motor to each
shaft, operate the propellers. An operator on the towing carriage to
which the model is attached regulates the speed of the model ship.
From the tests so made, calculations give the corresponding results for
the full-sized vessel.
Under the hydromechanics division is also carried out the design of
propellers in connection with the Bureau of Ships, and the testing of
model propellers based upon these designs. These model tests are
made in one of the two propeller tunnels already described.
TAYLOR MODEL BASIN—HOWARD 247
This division also carries out full-scale special tests aboard ships of
the fleet, usually at the time of their trials, such as turning trials to
determine the track of a ship under different conditions of speed and
rudder.
The structural mechanics division is concerned with all questions of
the strength of ships’ structure, vibration, and related subjects.
The work in structural mechanics at the model basin had its incep-
tion a number of years ago in the thought that if the performance of
full-sized ships could be accurately forecast through experimental
work with models in a model basin, it should equally well be possible
to forecast the performance of the structure of ships by the use of
accurately constructed models, with proper technique in carrying out
the tests. This would permit gaining knowledge as to the performance
of such structures long before a ship itself was finished.
This work was started with elementary models of the hulls of ships,
and sectional models of the hulls of submarines. Proving successful,
it has been continued to the present time, until it now includes deck
and bottom structures, turrets and their foundations, and similar
projects.
The next problem undertaken in this field was the resistance of the
structure of ships to underwater explosions. It was soon found that,
for this work to be effective, fundamental knowledge must be gained
as to the nature of the underwater explosions themselves. With the
construction of the new Taylor Model Basin an extensive research
program was taken in hand to investigate the effect of the explosion of
small charges against simple diaphragms, and also to study the explo-
sions of charges themselves, by the use of extremely high-speed under-
water motion photography. From this research, information is being
gained as to the nature of explosions themselves, and their effect upon
the structure of ships.
A third most important work of this division is that of investigating
vibration of ships’ hulls and structural foundations, including support
of instruments and other equipment aboard ship. Some of this work
is done at the model basin but a large part of it is carried out aboard
newly commissioned ships of the fleet when undergoing their first
high-speed runs and gun-firing trials.
The work of the aeromechanics division, including the operation of
the two new wind tunnels, is concerned principally with wind-tunnel
tests of models of new designs of airplanes for the Bureau of Aero-
nautics of the Navy Department, and with tests to determine the effects
of modifications to improve the performance of existing designs.
Wind-tunnel tests are also made for the Bureau of Ordnance, and
619830—45——17
248. ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
other government departments, to assist them in special problems
requiring aerodynamic information.
To construct the various types of models which are used in the inves-
tigations which have been described, two separate shops, one wood-
working, the other metalworking, form an integral part of the estab-
lishment. The former exists particularly to manufacture the wood
models of ships, aircraft, or other forms which are tested, while the
latter constructs all special equipment, instruments, and other gear as
well as any metal models used in the tests in the establishment.
In its highly technical work which, in many of its aspects, involves
the measurement of infinitely small units of time, stress, and motion,
the Taylor Model Basin has taken a leading place in the development
of special instruments. As two examples in the field of instrumenta-
tion in which the organization has become preeminent, the work in
ultra-high-speed motion pictures and electronics should be mentioned.
The basin has taken a leading position in the development of high-
speed motion-picture equipment and technique to record the details of
lightning-fast phenomena such as shock and explosion, and also in the
development of electronic measuring instruments accurately to record
super-high-speed events such as the pressure curve of an explosion, or
to measure infinitesimally small changes in displacement for obtaining
data on vibrations and strains in structures.
From the preceding paragraphs it can be seen how large a part the
work at the Taylor Model Basin plays in the technical side of the war
effort. Every new design of ship, from aircraft carrier to landing
barge, is checked and tested as to its form and power; minesweeping
gear, insofar as its performance in water is concerned, is tested and
run in model or full size; special weapons and devices which operate
in or on the water are designed as to their hydrodynamic features; and
the vibration of new ships and their ability to withstand shock are
investigated. The list could be multiplied indefinitely.
This general description of the work undertaken and now under way
at the Taylor Model Basin, and the special items listed, would not be
complete without comment upon the quality of the technical reports
which make available for use the actual results from these tests and
projects. No matter how thorough and complete the technical studies
and tests themselves may be, if they are not so written up and presented
as to be understandable and clear for the use of the officials for whom
the tests and studies are made, they might as well not have been made
at all. Particular effort has been made in the preparation of better
and clearer reports by progressive development of reproduction meth-
ods, lay-out styles, and writing technique, so that these reports may be
readily understandable by those who desire to use them. The success
of these efforts has been made evident in the widespread demand for
TAYLOR MODEL BASIN—-HOWARD 249
Taylor Model Basin reports throughout this country and abroad as
well as by the various agencies of the Navy itself.
At present every effort of the Taylor Model Basin staff and its facili-
ties is being applied to the one end which is to contribute to the
maximum of their abilities to the early winning of the war. Pure
research must take a secondary place, but it is only through the pure
research carried on in peacetime and the skill so developed in the
solving of similar problems that quick and correct answers can be
found now for the urgent problems of the war.
The interest of the country in research has increased greatly in these
most recent years. It is greatly to be hoped that when peace comes
again this interest will not lag but will continue so strongly that this
establishment may continue to operate at its full capacity, so that
through the more extensive pure research then possible, technical
improvements in the design and construction of our ships and naval
weapons may increase. Thus, should war ever again be forced upon us,
we may feel that we have kept ourselves prepared to meet the technical
problems of that day.

RESEARCH FOR AERONAUTICS—ITS PLANNING AND
APPLICATION ?
By W. S. FaRREN
Director, Royal Aircraft Establishment
INTRODUCTION
The exceptional circumstances of the times make it impossible for
me to observe the letter of what I know is the Institute’s wish in the
choice of a subject, though I believe I can conform to itin spirit. The
Institute desires that the lecturer shall deal with some scientific or
technical subject on which he is, or has been, personally engaged, and
shall not indulge in broad surveys. There will come a time when the
lecturer’s chief difficulty will be to choose from the embarrassingly
rich store of knowledge which has accumulated during this war. But
for the time being the door of that store cannot be opened in public.
Moreover, I doubt whether the part that I have played in a large
number of fascinating and exciting investigations during the last
4 or 5 years is such that I could fairly deprive those who have done
the work of the privilege of speaking about it. This is a difficulty
that has always faced those who hold such positions as mine, and one
of which your Council were no doubt well aware when they invited me.
I have long been concerned with the problems that arise in applying
the advances in knowledge which research for aeronautics has brought
us and with the problems of planning the course of current research
and of providing appropriate and timely resources for future research.
I believe that these are matters that might with advantage be surveyed
as a whole, in a scientific spirit. Moreover, I believe that the subject
can usefully be treated in a purely personal way, and I have through-
out drawn on my own experience.
From this it follows that any conclusions I draw apply only to the
circumstances in my own country, or rather to my own interpretation
of what they have been and may be. It will be for you, not for me,
to say whether you find them in any way relevant to circumstances

in the United States. But the intimate relations that have existed
between workers in America and in England, in the field in which
my interests and responsibilities lie, give me the courage to believe that
a summary of my experience may be of interest to you, and worthy of
this occasion.
THE AIM OF RESEARCH
Research is one of the things we all understand but find difficult
to define. In the foreword to a recent pamphlet on Industrial Re-
search, Sir Harold Hartley defined it as “a habit of mind which makes
us attack every problem, big or small, in an orderly, systematic way,
using if possible the advantages that modern science can give us.”
I remember Lord Rutherford, in a characteristically expansive and
emphatic mood, using almost the same words. I invite you to note
the two words “if possible.” There are limits to what “modern science”
can do for us. In research, as in other human activities, we depend a
good deal on our wits. There is limitless opportunity for intuition
and initiative.
The aim of research is to produce a theory firmly supported by
experimental evidence. Though necessarily incomplete, it must be
a close enough approximation to serve the man who has to make
things work. I trust you will not infer from this statement that I am
interested in research only for what I can get out of it. I have known
the thrill of working solely for the fun of it. But I am interested,
for the time being, in research with a clear and unmistakable objec-
tive—the discovery of how to make better aircraft. It is my experience
that, for such research to be not only fruitful but timely, it is essential
that the practical problems involved in its eventual application shall
always be clear to those who are doing it. This need not in any way
restrict their freedom. Indeed, they can gain immensely from contact
with those upon whom the burden of applying their work is placed.
The theme I have taken is indeed that it is only by intimate and
wholehearted collaboration between the research worker, the designer,
the constructor, and the user that research can be intelligently planned,
pursued, and applied.
THE INDEPENDENT WORKER IN RESEARCH
As a preliminary I propose to give you an example from my earlier
experience which I feel puts the point as it appears to the independent
research worker.
I have been personally concerned with research in flight for nearly
30 years. The two chief aerodynamic problems have been, and still
are, the reduction of drag and the improvement of stability and con-
trol. Throughout, these problems have been attacked in the light of
RESEARCH FOR AERONAUTICS—FARREN 253
the practical questions thrown up by continuous contact, on the one
hand, with those who design and build aircraft and, on the other, with
those who use them. In my experience it has been this intimate rela-
tion between the three parties which has made this work so continu-
ously exciting and, I believe, profitable. On looking back I cannot find
any example that convinces me that we should have moved more
quickly or more certainly had work on the fundamentals been divorced
from that on problems of the moment.
It is true that at times, while we were developing our theory, we
had the advantage—and this adds to my point—of individual work
going on in flight, under conditions which I now believe to have been
ideal. When I was one of the team who worked on these subjects at
Cambridge, we often felt that we could do more, or do it more quickly,
if only we had more of something—men, airplanes, workshops—but
chiefly more hours in the day. In truth, I think we did as much as was
physically possible without enlarging our organization, and, if we had
done that, our work would have changed in character and would, I
believe, have been less effective. That it had effect, and quickly, was
due to our close relation with the establishments that had the necessary
resources to exploit it for practical purposes with which they were
intimately acquainted. They seized it and rapidly developed it. Its
practical effect can now be seen not only in many aircraft but in the
research equipment and programs of work.
You will remember Sir Melvill Jones’s first Wright Brothers lecture,
in which he described some of the work I have just referred to on the
boundary layer. From my own share in that work I can say that we
were profoundly excited by the problems themselves and by the fasci-
nation of trying to solve them by experiments in flight. But we were
stimulated, and all our discussions were illuminated, by the realization
of the potential application of their results. This we obtained from
our constant personal contacts with the experimental establishments
and with aircraft designers.
Thus my experience leads me to the conclusion that, while there
should be no explicit attempt to divorce work on basic problems from
that on immediate ones of narrower range, the fullest encouragement
and practical support should be given to independent workers. What
form this should take I hesitate to define. My own preference is not
for large endowments to institutions in the hope that they may attract
good men. I would rather make generous finance available through
some semi-independent advisory organization when the need is made
clear by the development of the work. This may be either in cash or
in kind. We at Cambridge had very little money, but the country
supplied us with airplanes and maintained and renewed them. My
only concern is that the ponderous workings of the machinery of gov-
254 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
ernment, when finance is involved, may result in the essential help
coming too late. One day we shall learn to trust our scientific advisers
with a reasonable fraction of our money on a block-grant basis and
ask no account except at longish intervals.
RESEARCH ON A LARGE SCALE
I come now to that class of research for aeronautics whose scale is
such that success depends on planning of large experimental resources
and on planning so that application to practice may meet the foreseen
needs of design and its capacity to exploit new discoveries.
We must, in my view, plan research for aeronautics in three phases.
First, we must relate all our main effort to advances in basic theory.
Odd pieces of information without a clear, strong framework are
worth little. Second, we must provide the experimental information
by which theory may be built up and its limitations recognized and
reduced. Third, we must ensure that experimental application is
made in such conditions that the practical value of the theory is
confirmed.
There are three chief parties to this undertaking: first, those who
are by trade workers in the field of theory and those who have the
flair for the associated exploration by experiment; second, those who
make use of the results in the design and construction of aircraft; and
third, those who use the aircraft and on whom we rely to exploit the
product of the efforts of the first and second. The extent to which
these should enter into planning of research can be illustrated by an
example—the problem of reducing the cooling drag of power plants.
That it is possible to reduce the power wasted in cooling an airplane
power plant to 2 percent or less of the brake horsepower was estab-
lished many years ago. Indeed, it was shown that at flight speeds that
were then within sight and have now been passed the cooling could be
made to help to propel the airplane. But the cooling of a power plant
is a matter that goes far beyond broad conceptions of this kind. It
involves complex flows of air and liquids, demanding regulation to
meet the varying conditions of flight and high standards of reliability
in functioning and of ease of maintenance, which are of the greatest
concern to the user.
It was not until other developments had reduced the rest of the drag
so much that the power-plant drag was a dominating factor that the
designer became convinced that the problem demanded his serious
attention. He has finally succeeded in producing cooling systems that
are no less reliable and have a much lower drag. The user accepts
the slight additional embarrassment to maintenance in return for the
higher speed and greater range.
RESEARCH FOR AERONAUTICS—FARREN 255
But the practical problems of achieving the full result are still only
partially solved. Few power plants will stand up to critical examina-
tion on such points as low-loss ducting or airtight cowlings. It is a
difficult engineering problem to design and make such features at the
same time light and easily removable and replaceable without damage.
Throughout the whole history of this development there has been
intimate association between the three parties chiefly concerned. But
in my view we can now see that a better planning of the enterprise as
a whole would have saved much time and waste of work. In particu-
lar, an earlier realization by the designer of the outstanding advance
that was within his grasp would have brought him to a closer coopera-
tion, on strictly practical lines, with his only source of specific infor-
mation—the research establishments. They in turn were backward in
that they did not provide themselves with the right material by which
alone convincing information, directly applicable to practical prob-
lems, could be obtained. This is a case in which I believe the enlight-
ened user, if correctly advised, could have forced the pace.
A SURVEY OF 25 YEARS’ ACHIEVEMENT
The final criterion of our success in using the knowledge with which
we have been supplied is the extent to which the product of our efforts
has improved as time has passed. The curve of advance is not a
smooth one. Over longish periods we often see little beyond a slow
rise in achievement, and we tend to believe that there is little more to
be expected. Then there comes something in the nature of a trans-
formation. It is often ascribed to a single cause and, generally, one
can say that there is an outstanding stimulus. But if we compare the
final product—in this case, the airplane itself—before and after the
event, allowing a long enough time for the situation to reach a fairly
stable state, we can make a fair assessment of the relative weight of all
the influences which have contributed to the change. I believe such
an examination of the advance of the airplane between say 1917 and
1942 is useful in providing us not only with a means of examining how
far we have been successful in using the results of research but also a
guide to the part played by sheer engineering skill and initiative.
Finally, it may serve as a base from which we may survey some of the
potential advances that are now opening out to us and judge what
resources we shall need in order to achieve them.
I shall take two typical aircraft that were in general and successful
use in 1917 and compare them with two modern aircraft of similar
duties. Naturally there are striking differences, and we shall find no
difficulty in tracing them to their sources. But perhaps equally strik-
ing are the characteristics that have apparently undergone little
256 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
change. I think, however, that we shall see that the effort to preserve
them unchanged has made as high a demand on research and engi-
neering skill as that required to produce the more obvious improve-
ments.
During the last war the Royal Aircraft Factory (which became the
Royal Aircraft Establishment in April 1918) produced many designs
for aircraft which were constructed in large numbers. One of the most
successful was the S. E. 5, a single-seat fighter with a 180-hp. Hispano
Suiza engine. It had a creditable history as a fighter. I propose
to compare it with a Spitfire. Then I shall take the Handley Page
0/400 twin-engined heavy bomber and compare it with a Lancaster.
I shall not be giving away any information to our enemies. They
are well acquainted, in more ways than one, with both Spitfires and
Lancasters. Some of them may even remember the S. E. 5 and the
0/400. For my purpose it is quite sufficient to take examples of marks
of the modern types whose performance has long been surpassed.
Let us first look at them in general outline. Figure 1 shows the
1917 fighter. In Figure 2 its specifically military features have dis-
appeared and around it is the outline of the Schneider Trophy
streamlined monoplane, the essential product of the period between
the two world wars. Figure 3 shows the 1942 fighter. In Figures
4, 5, and 6 is shown the transition from the 1917 bomber, through the
streamlined airliner, to the 1942 bomber. The most obvious differ-
ences are the change from biplane to monoplane and the general
cleaning-up due to enclosing the crew, abolishing external wing
bracing, and retracting the undercarriage. Comparing them type
by type, the over-all dimensions are not very different. The Spitfire
has the same wing surface as the S.E.5, about half the drag, nearly
twice the strength, three times the speed, four times the total weight,
four times the military load, and seven times the power. The Lan-
caster has about half the drag of the Handley Page 0/400 on the same
span of wings and about three-quarters the wing surface. Its total
weight is nearly five times as great; the wing loading, over six times;
the power, seven times; and the military load, with a 25 percent
greater range, over eight times. Let us inquire how some of these
improvements have been made.
DRAG REDUCTION
The change in drag coefficient Cp, is of first interest. I have not
found it possible to get accurate figures for the older aircraft, but
they are approximately 0.039 for the fighter and 0.046 for the bomber.
The corresponding modern figures are 0.022 for the Spitfire and 0.030
for the Lancaster. Thus, per square foot of wing surface, the total
drag has been reduced to about 55 and 65 percent of the 1917 standard.
RESEARCH FOR AERONAUTICS—FARREN 257

FIGURE 3.
258 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
FIGURE 5.
FIGURE 6.
RESEARCH FOR AERONAUTICS—FARREN 259
Comparing the two fighters in more detail, we find first that the
wing surface is the same for both. Disregarding induced drag (or
assuming it to be the same fraction of the whole in each), the top
speed at the same height will be proportional to the cube root of
the thrust power divided by the drag coefficient. Since the pro-
peller efficiency is near enough the same for both, we may use brake
power. Taking ground-level powers in both cases—180 hp. for the
Hispano and 1,250 for the Merlin—the ratio is about 7. Thus the
contributions to increase of speed are:
g 0.039\14
by reduction of drag — Suleal
by increase of power (7)? =1,92
The product of these figures is 2.33.
If we assume that by supercharging it is possible to keep the Merlin
power constant up to say 25,000 feet, where the density is approxi-
mately halved, we shall get a further rise:
by supercharging™ (2)! = 1.26
The total ratio of increase is therefore nearly 38.
At this point I feel that the engine people are feeling very pleased—
and we have good reason to acknowledge the success of their effort.
But these figures as they stand do less than justice to the aerodynamic
contribution. All the cooling required by the seven-times increased
power has been provided and yet the aircraft has no more than half
the drag per square foot of wetted surface.
How have these improvements been made? Let us look first at
the drag account (table 1). To the saving of 47 pounds, the most
obvious contributions are from the elimination of wing bracing and
undercarriage—31 pounds in all. But the body and cooling drag is
actually reduced by over 10 percent in spite of the sevenfold increase
of power.

For the bomber, the reduction in (po is rather less than for the
fighter on account of the drag of defensive armament, but otherwise
the influences operating have been much the same.
Toward the end of my paper I shall say something about what
further improvements in drag are in sight and what problems we
have to solve in order to achieve them.
WEIGHT ANALYSIS
Let us look next at the weight picture. The Spitfire weighs four
times as much as the S. E. 5; the Lancaster, nearly five times as much
as the 0/400. What has made it possible to carry so much additional
weight per square foot of wing surface—for the fighter four times,
for the bomber six times as much? In the airplane itself, first, the
development of flaps giving higher maximum lift coefficient and higher
drag; second, power plants of much greater power per unit weight;
and, third, constant-speed propellers to make the power fully
available over a wide speed range. But larger and better airfields,
permitting higher take-off and landing speeds and better flying tech-
nique, have contributed even more. The effective maximum lift
coefficient has risen by about 65 percent. Even so, the touch-down and
take-off speeds, with the higher wing loadings, are 50 to 80 percent
higher.
A comparison of the weight analyses and load factors of the fighters
is given in table 2. As a matter of interest, I have given also the
weight analysis for the FW 190.
How has this remarkable similarity of weight distribution been
maintained? From the structural point of view, it is essentially by
increasing wing loading four times that it has been possible to go
from braced biplane to monoplane with nearly double the primary
strength, from fabric covering to a metal skin, and from a fixed to a
retractable undercarriage with no significant changes in percentage
structure weight.
From the point of view of the power plant, we have to record a rise
in the net output per pound of complete plant in the ratio of about
7to4. The complete plant of 1942 includes both constant-speed pro-
RESEARCH FOR AERONAUTICS—FARREN 261
peller and supercharging arrangements by which the power is main-
tained up to heights at which the air density is half, or even less than
half, of that at ground level.
For the same percentage fuel weight the range is some 40 percent
better at a much higher cruising speed. Specific fuel consumption
is much the same in spite of the great improvement in specific per-
formance achieved in the face of the burden of supercharging. We
must acknowledge here the tremendous contribution of high-octane
fuel.
We are left in both cases with about one-sixth of the total weight
for the man, his equipment, and armament. The weight of the man
is the same as it was. In 1918 it exceeded that of his whole fighting
equipment. Today it is but a fraction of it. The weight of the
bullets alone in the modern fighter exceeds that of the whole arma-
ment of the S. E. 5.
For the bombers, weight analyses are strikingly different from
those of the fighters (table 3). In 1917 we thought it natural for the
structure weight of a large bomber to be greater than that of a small
fighter—40.4 percent compared with 29.7 percent. In fact there was
a view, widely held and expressed somewhat forcibly by Dr. Lan-
chester, that aircraft of larger span than say 100 feet would be
uneconomical because of the operation of the square-cube law char-
acteristic of geometrically similar structures. Designers, aided by
research, have managed to avoid the consequences of this law. They
have been so successful that the structure weight percentage for the
Lancaster is practically the same as that for the Spitfire. The load
factor of the bomber is, of course, much lower than that of the fighter.
But it is probably little different from that of the 1917 bomber.
The progress that has been made is therefore remarkable.

In the achievements summarized above I think aerodynamic, struc-
tural, and power-plant improvements can fairly claim about equal
shares, and to each, I suggest, the contributions of research and of en-
gineering skill and ingenuity have been about equal. To pursue the
analysis would lead me away from my main theme. But I think we
may, with advantage, examine the history of effort in the structural and
262 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
aerodynamic fields a little further in order to show the nature of the
difficulties that have been met and the methods by which they have been
overcome.
STRUCTURAL DEVELOPMENTS
In 1917 the great majority of aircraft structures were made of wood
and steel. Light alloys were little used. Wing surfaces were covered
with fabric, and torsional stiffness requirements were met by the bi-
plane wing structure. Today, with few exceptions, we use light alloy
for the primary structure, and torsional stiffness is derived in most
cases from the light-alloy sheet wing covering. The very con-
siderable improvement that has been made in aluminum-rich alloys
contributes chiefly to the wing spars. There is as yet no marked sign of
a development in their properties or application which will reduce the
weight involved in meeting torsional stiffness requirements. This is, of
course, because these involve stability rather than strength character-
istics.
I do not suggest that the enormous effort that has been put into im-
proving aircraft materials has not contributed to the maintenance of
structure weight at a remarkably low figure in spite of increases of
speed, strength requirements, and size. But it is significant that the
Mosquito airplane, which is made almost entirely of wood, has a struc-
ture weight as low as that of the equivalent metal airplane.
One feature of the, modern aircraft which has undoubtedly con-
tributed to a more economical wing structure, in particular, is the great
increase of wing loading and therefore of wing weight per unit area,
which has made it possible to employ the material to much greater ad-
vantage—i. e., to have a smaller percentage of relatively lowly stressed
material. This brings me to one of the outstanding contributions of
research to aeronautics—namely, that derived from the investigation
of the strength of actual structures in close association with theoretic
analysis. It is by such work that it has been possible to increase greatly
the useful load of practically all aircraft now in use. The most
thorough mechanical testing of aircraft structures undoubtedly pays a
high dividend. These tests have not only shown us that our methods of
design have led to general forms of structure well adapted to meet the
demands on them, and fundamentally economical in character, but have
enabled us to discover where our knowledge of the detailed distribution
of stresses is inadequate and at the same time to improve that knowl-
edge and to strengthen the structure against unforeseen local weak-
nesses.
The determination of the loads that the structure is called upon to
bear is fundamentally a more difficult problem. We are greatly in-
debted to such methods as the V. G. recorder, but these give us only
over-all figures that, useful as they are, throw little light on the load
RESEARCH FOR AERONAUTICS—FARREN 263
distrivution in flight. We have now available a method of great po-
tency in the electrical resistance strain gauge. This is being used with
great effect on a large scale in laboratory tests, and its application to
measurements in flight is being rapidly developed. It will undoubtedly
prove to be one of the greatest contributions of the research worker to
improvement in the structures of aircraft.
Possibly the greatest achievement of the research worker in the field
of aircraft structures is in discovering how to avoid the dangers of what
we comprise in the term “flutter.” In my view, there is in the whole of |
aircraft engineering no better example of the power of mathematical
analysis, of ingenuity in experiment, and of skill in interpretation.
The successful attainment of very high speeds, with a remarkably small
number of serious failures, can only be ascribed to the most skilled use
of all these resources, guided by systematic review of the results of their
application. Direct experiment in flight—the only satisfactory
check—is almost impracticable. Laboratory determination of reliable
numerical values of the essential quantities involved is extremely dif-
ficult. Much more information on these is essential for progress, and
here the designer can justifiably demand all that research can provide.
STABILITY AND CONTROL
Up to this point I have said nothing of the contribution of research
to the production of stable and controllable aircraft. I am glad to
say that the time is now long past when lack of stability is regarded
by anyone as a virtue in an aircraft. In fact it is unquestionably a
most serious defect, whatever the duty of the aircraft. But it has
always been difficult to define the necessary or desirable margins of
stability and the associated general stability and control character-
istics. The designer must, however, have the requirements expressed
in terms that can be reflected in his lay-out, both as a whole and in
detail. He must be able to judge fairly accurately how the changes in-
evitable as a design develops will react on the stability and control,
and he must have at his disposal means of dealing economically with the
consequences both of the variation of load distribution resulting from
operational conditions and of the changes involved in the development
of the aircraft.
There is a good deal about the stability and control of aircraft in
which there has been little apparent change over the period covered
by the examples I have taken. I believe, however, that this is simply
because the desirable general characteristics were attained by about
1918. Since then our main problems have been, first, to preserve them
substantially unchanged in spite of the profound changes in the form
of aircraft and, second, to enable the same man to control much larger
and much faster aircraft.
619830—45——18
264 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
The foundations of stability and control theory were laid, and well
laid, long ago. Much labor has been spent on expanding it to embrace
new developments, such as structural distortion, and on the analysis
of the controlled and uncontrolled motion of aircraft. A vast amount
of experimental evidence has been accumulated. Much of this, how-
ever, is related rather to specific problems than to the systematic devel-
opment of an understanding of the matter. There is room here for a
wholesale improvement, particularly by an attack on a wider front in
flight. I am not among those who criticize our record here on the
grounds that we did not undertake enough basic work at the time when
the airplane, as we now know it, first crystallized. I regret that cir-
cumstances made it impossible to give this work high priority. Had
we been able to do so, we might have avoided many troubles and saved
much labor. But I do not believe that, on the balance, we would have
reached our objective—usable aircraft—more quickly. We relied on
our past experience, on our ability to improvise, and—most significant
of all—on our conviction that the theory available was soundly
founded on experimental evidence. We discovered, by the attacks we
were forced to make on troubles as they arose, much more about sta-
bility and control than most of us believed there was to learn. Thus,
and I believe only thus, could we have advanced at the rate we did.
It is an excellent example of the interworking of research and
application.
In the field of control balance we have made tremendous advances
in the face of difficulties that are sometimes hardly appreciated. The
1917 bomber operated at speeds—80 to 100 m.p.h.—at which the pilot
could provide the forces necessary for control with little or no aero-
dynamic balance. Take the 0/400 ailerons. The maximum hinge
moment required was probably equivalent to a force on the pilot’s
hand of the order of 50 pounds, with ailerons on which the aero-
dynamic balance was probably no better than one-half. In the Lan-
caster the same movement of surfaces of about the same size is required
at 300 m.p.h., requiring nine times the forces. The pilot is no stronger,
so the aerodynamic balance must reduce the hinge moment to say one-
eighteenth of that of unbalanced ailerons. This is a difficult require-
ment but it has been met.
Suppose we put up the weight at the same wing loading to 100,000
pounds, one and one-half times that of the Lancaster. The linear
dimensions will rise in the ratio 1.5/7 and the hinge moment at the
same speed in the ratio 1.5 */?._ The aerodynamic balance must there-
fore reduce the hinge moment in the ratio
1/(2) (1.5)%/2(3)2=1/30
A similar argument leads to a figure of 1/400 if the weight is increased
to 500,000 pounds. We can certainly achieve 1/30 and possibly 1/400
RESEARCH FOR AERONAUTICS—-FARREN 265
in ideal conditions. But it is doubtful whether this is a wise policy,
since we can hardly expect to define or to maintain the shapes of
surfaces sufficiently closely. Power-operated controls have been
avoided so far, but it is unwise to assume that we can neglect them
indefinitely. There seems to be no good reason to be doubtful of our
ability to make them reliable.
POWER-PLANT DEVELOPMENTS
I do not propose to extend this survey to the two other main factors
that have contributed to the changes we have seen in aircraft—the
power plant and the propeller. I have already quoted some figures
that show how remarkably the reciprocating engine has advanced.
I have also said that there have since been further advances, which,
however, serve rather to emphasize the comparisons I have made than
to invalidate them. This is because there have been accompanying
changes in weight and other characteristics that leave the main con-
clusions substantially unaffected. Our debt to the engineers who,
aided by research, have achieved these results is immense.
To the constant-speed propeller the performance of aircraft must
also acknowledge a great debt. But the flying man is even more
grateful for what it has provided—almost complete freedom from his
chief anxiety, namely, the liability to misuse his engine. We now look
forward confidently to new methods of propulsion for aircraft. But
I believe the propeller has a long and useful future before it and one
in which research will play an outstanding part.
SUMMARY—THE TASK OF RESEARCH
I trust that this short survey has gone some way to show why I am
convinced that the research worker and the engineer must work to-
gether if we are to make significant progress. In his James Forrest
lecture to the Institution of Civil Engineers in England, Dr. Southwell
said that “Aeronautical engineering is ordinary engineering made
more difficult.” If that was true in 1930, as I believe it was, it is more
than ever true now. We can see clear prospects of great advances in
aircraft in size, in performance, and in safety. The curve of improve-
ment against time shows no real signs of flattening out. But we shall
need all our ingenuity to avoid or to overcome the barriers which we
can see ahead.
I think the engineer has made good use of the outstanding contribu-
tions of research for aeronautics. If at times he has appeared slow to
appreciate the significance of new developments, he has a good excuse
in his preoccupation with producing something on which we can rely.
This is a sufficiently serious responsibility and one that he has borne
with credit. But it is this very preoccupation that emphasizes the need
266 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
for employing as part of an engineering organization men competent
to detect those advances in knowledge which are potentially valuable
and to work out the technique of applying them.
The research worker himself is not blameless in this respect. We
can call to mind the case of Mendel, the significance of whose work in
genetics was not recognized until he had been dead many years. His
case is an example of discovery not appreciated because it is too far in
advance of the general state of development of the science. Dr. Lan-
chester’s books Aerodonetics and Aerodynamics contained much
which may perhaps be regarded in the same way.
The instances I have mentioned may, of course, be regarded as classic
examples of the difficulty of disseminating knowledge. As the volume
of knowledge increases, this difficulty grows. In the hall of Trinity
College, Cambridge, there hangs the portrait of William Whewell,
sometime Master. It is said that he was the last man to know all
knowledge. He died in 1866.?
But the research worker has, in my view, a part to play in “putting
across” the results of research. It is reasonable to ask that he should
put his results in such a form that they can be used. To those who
feel that this is hardly worthy of so much of their time and attention,
as it certainly demands if it is to be well done, 1 would command
the example of one of the greatest workers in aeronautics, Hermann
Glauert. Every one of his outstanding contributions to aerodynamics
was finished in such a form that the method of its application was
made clear. I am not aware that this in any way detracted from the
value of his work on whatever basis it may be judged. And I know,
from my long and intimate friendship with him, that he regarded
it as the natural method, and indeed the only one that would satisfy
his sense of craftmanship.
PROBLEMS OF THE IMMEDIATE FUTURE
If this review leaves us confident of our powers to use effectively
the results that an alliance between research and engineering ingenuity
can provide, as I think it should, how should we shape our plans for
the future? Let us look for a moment into what the future may hold
for us in one field alone: still further improvement in performance—
in speed and in range.
Within the limits of our present knowledge the most economical
way to fly faster is to fly higher. Let us suppose that we can extend

the range of operation of power plants so that propulsive power is
independent of height. Taking an airplane with the characteristics
of the Spitfire (table 1), and assuming that Cp)=0.022 under all con-
ditions, the curve of speed against height is shown in figure 7 labeled
A. The line of sonic speed, Mach number=1, is crossed at 65,000 feet.
In practice the effect of the compressibility of air begins to be felt at
about M=0.65 at 33,000 feet at a speed of about 430 m.p.h., and the
rapid rise of Cpo with U/ brings the curve for greater heights down
to about the level of curve A,. The loss of speed is very large.

ence of reduction of Cpo and of compressibility.

wing loading, 28 lbs./sq. ft. ; aspect ratio, 5.6.
If, by devising forms that will ensure some measure of laminar
flow, we can halve Cp, and at the same time avoid compressibility
effects, we get curve B. But if compressibility has the same kind of
effect as on the original airplane, the result will be to depress the
speed to curve B,. Similarly, reducing Cp. to one quarter of the
original value, we get curves C and C.
If we are to reach really high speeds economically, it is clear that
we must devote at least as much effort to avoiding or reducing the
effect of compressibility as to reducing the “low speed” value of Cpo.
On the other hand, at speeds at which it is likely to be economical
268 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
to cruise for long distances, compressibility will for some time be
relatively unimportant and laminar-flow forms offer outstanding
prospects. In round figures range and economical cruising speed are
inversely proportional to the square root of Cp. If we can halve
_@po, both range and cruising speed will rise by 40 percent.
We must not dismiss too lightly the possibility of cruising economi-
cally, at great height, at very high speeds—speeds at which com-

pressibility may well have a dominating influence on design. With a
laminar flow extending over the majority of the surface of the air-
plane we may reasonably expect to be able to cruise at 450 m.p.h.—
a Mach number of about 0.7. Considering the airfoil alone, because
of necessary thickness and camber, sonic speed will occur at a point
near the surface when the lift coefficient reaches a certain value.
Hence, the wing loading must not exceed a figure dependent on the
RESEARCH FOR AERONAUTICS—FARREN 269
height. At the heights at which it is likely that such speeds will be
economical, from the power aspect, calculation suggests that rather
low wing loadings will be required. Figure 8 shows the results of
some preliminary calculations on this point. The wing loading cor-
responding to the critical conditions is sensitive both to airfoil thick-
ness and to height. For example, assuming 60 percent of laminar
flow, 15-percent thickness, and a camber appropriate to the lift co-
efficient, the critical wing loading at 35,000 feet is 28 pounds per square
foot; or for a 16-percent thickness, 20 pounds per square foot. At
30,000 feet the corresponding loadings are 44 and 35. If these calcula-
tions are sound, the effect on the general economics of the situation
will be marked. Here is another reason to justify extensive theoretic
and experimental work in this field.
Thus we see both the barriers to progress which now face us and
the potential rewards that will be ours if we can succeed in surmount-
ing them. I return to my main theme—the research worker, the
designer, the constructor, and the user must join forces and, each
fortified by the confidence and help of the others, plan the work that
is needed to provide the information, pursue the investigations in
the conviction that the aim is worthy of the effort demanded, and
apply the results to produce better airplanes.
From aerodynamics we demand not merely the bare solution of the
problem of forms providing laminar flow, relatively immune from
effects of compressibility. We require specific information covering
the whole airplane, including its propulsion, stability, and control.
It may be that the whole lay-out of the aircraft will be different from
that to which we have been accustomed. It is for the aerodynamic
people to say, but they must base their opinions on a sound foundation
of experiment.
From structural research we require to know what schemes of
structural design are most likely to provide the necessary precision
of form and superficial smoothness and how to cope with new strength
and stiffness requirements. Aerodynamics must supply information
on the loads that will be met in flight, and much thought must be given
to the meteorologic conditions that will be encountered.
In the future it will be impossible to consider the airplane engine
and the airplane as separate enterprises with conflicting requirements.
The thermodynamic problems will be aerodynamic also. Their joint
solution will throw up more than enough of the design problems at
which the power-plant engineer excels.
Will the transformation of the energy of the fuel into thrust de-
mand a propeller or a jet or a combination? There is no single
answer. It will depend on the duty of the airplane. But the propeller
designer will find that his task will tax all his ingenuity.
270 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Upon the airplane designer will fall the burden of combining into
a working proposition the contributions of all his collaborators. He
will need to provide for pressurized cabins, ice-free surfaces, and
the many indispensable aids to control, navigation, take-off, and
landing.
To the user the prospects are such that he should spare no pains in
encouraging the research worker and the engineer in their difficult
tasks. He must support them to the full in obtaining the resources,
in men and material, which will be essential for solving their prob-
lems. And he must contribute, as a member of the team, the opera-
tional information that will guide their efforts at all stages.
The experimental resources that such work demands are large.
They must be generously planned to provide the greatest possible
scope and flexibility. It will take time to devise and to create them,
and during this time we shall inevitably meet further difficulties whose
exact nature we cannot yet foresee. We may be confident in our ability
to adapt and to improvise, but we must ensure that the basic equip-
ment is on an adequate scale.
THE MANAGEMENT OF RESEARCH FOR AERONAUTICS
I have left until last such remarks as I have to make on an aspect
of planning research for aeronautics to which you may feel I should
have paid more attention—namely, the organization and management
of the work on the scale that the scope and complexity of the prob-
lems demand. In what I said earlier I have emphasized my belief
in the value of the independent small team of workers, who necessarily
work on a small scale with relatively small equipment, and on one
or at most a few problems. But we must recognize, perhaps reluc-
tantly, that we have problems to solve which cannot be handled suc-
cessfully in that way.
It is not merely the large size and complexity of the equipment
required which forces us to face the task of managing large research
undertakings. It is rather that the many problems we must attack
are interdependent, and that success in dealing with them depends
on assembling and coordinating the efforts not only of a team but
of many teams of workers. As in any large undertaking we have to
break the work down into parts. Each part is the primary responsi-
bility of a group of specialists under a leader. But the parts must
be welded into a whole, and in this welding lies the problem of
management.
I believe that the problem is best approached not from the top but
from the bottom—from the point of view of the individual member of a
team. What does he need in order that he may do the best that is in
him? In my experience, he needs the following:
RESEARCH FOR AERONAUTICS—FARREN a a |
(1) A clear, unambiguous statement of the ultimate objective.
This must be more than a statement of the specific problem. It must
relate it to the general picture of which it is a part. Thus he will
know why the work is being done.
(2) An opportunity to give his own views on the value of the under-
lying ideas. The basic plan must be, in part, his own. Thus he
will start with a sound conviction that the plan is a good one.
(3) An immediate leader in whom he has confidence, who will
inspire him, help him, and keep him up to date in all the relevant
parallel work on related problems. Thus he will retain the good
spirits in which he starts.
(4) Sufficient resources to enable his work to progress at what is,
in his judgment, a speed commensurate with the importance of the
objective. Thus he will feel that the value of his work is recognized
in the only way that means anything to him.
This formula can, in my experience, be applied to groups of work-
ers under a central management or to separate establishments under
a central direction. And the difficulties that one meets in applying
it arise not from its shortcomings but from conscious or unconscious
neglect of its essentials.
Looked at in this way, such questions as the ideal size of research
establishments cease to be of any great significance. Just as a team
must have a leader who knows all about the work being done by its
members, so a group of teams must have a leader who is recognized
by them to know enough about their work for him to be able to guide
it to its common objective. The limit of economical size of a com-
plete unit is set not by some arbitrary formula but by the simple fact
that no one man can know enough about work in more than a few
fields to be able to inspire real confidence in his team leaders or
their teams. The control of large equipment, the management of
numbers of skilled industrials, and the commonplace daily problems
of facilities are matters of consequence, but they are not the real de-
termining factors. In any event they are well understood and can
be broken down and shared among a properly balanced staff.
I would summarize my views on this question as follows. There
is no single or simple formula by which to determine the best method
of handling research. But I believe there are a few simple prin-
ciples in the light of which each particular situation may be reviewed
and a good solution found.
CONCLUSION
You will see that my experience has led me to the view that the
record of science and engineering in aeronautics is a creditable one.
It justifies us in demanding the means of extending our efforts into
272 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
those new fields that we can now clearly see. The task of organizing
and managing the work, of devising and constructing the equipment, |
and, above all, of leading those upon whose efforts success will in
the end depend is one of absorbing interest.
What the world will make of our efforts is a matter on which I
regard it as unprofitable to speculate, at any rate here and at this
time. I am an engineer in a world where good engineering, skillfully
used, means survival and bad engineering means the end of what I
believe to be a good way of living. So I am content for the time
being to confine my efforts to the work in hand and to leave phil-
osophic speculations on its value, on some absolute scale which I con-
fess eludes me, to those who can find time or inclination for it. For
this reason I have confined my attention primarily to research for
aeronautics as used in war. There is another reason—I have spent
the best part of my life on work with this as its first aim in the con-
viction that it had to be done.
But I am an incurable optimist. I believe that we shall succeed
in our present effort—in which the share of research is to provide
information by which aircraft and their equipment can be steadily
improved and used to greater effect. When we have achieved our
immediate aim, I do not doubt that much of our work will be put to
uses that are more to my taste and to yours.
In the end, however, it is with the scientific and technical advances
in the means of flight that we are here concerned. So far we have
had a mere 40 years in which to show what we can do. It has been my
purpose to point, in the light of my experience, to what we must do
now to discharge the responsibility that is laid on us so that those
who will follow us may find a fair field in which to explore the end-
less vista of opportunity which will le before them.
HUMAN LIMITS IN FLIGHT?

A modern aircraft will climb in a few minutes to heights at which
the air is so thin that it will no longer support life. It can turn and
maneuver so fast that the pilot may easily be rendered unconscious
from the mechanical forces which it imposes on his body, and in an
aircraft which is moving rapidly in three planes of space the pilot
can be subjected to stresses beyond the limits which the human body
can stand.
The adaptation of which the human body is capable to new sur-
roundings and conditions can play a considerable part in fitting man
to these new conditions; for example, airsickness which many suffer
on first flying in rough air or doing aerobatics, in most people soon
passes off and they become adapted to motions which at first perplex
and incapacitate them, though a few never become completely adapted.
But there are several stresses placed on man in aircraft that cannot be
met by any unconscious adaptation, which require equipment specially
designed to meet them. Some of the necessities are obvious, such as
windscreens to protect the man from the great wind pressures at
high speed and a heat supply from the engine or special clothing to
keep him warm in the Arctic cold of the stratosphere. His senses must
be extended by a set of blind-flying instruments so that he may know
his altitude and movement in space when in clouds or at night. He
must learn to believe the instruments against his senses for these are
no longer a reliable guide when he may be moving at varying speeds
in any direction, in fact they will often be wrong. The human limit
of visual range by day and especially by night is of paramount impor-
tance in flying.
But beside the stresses from wind pressure, cold, vibration, and
noise, the pilot’s body must also be protected from other less obvious
stresses and here I propose to deal particularly with the two greatest

Britain, vol. 32, pt. 3, 1943.
273
274 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
stresses which an aircraft puts upon the pilot—those due to accelera-
tion or rapid change of motion and those due to high flying in the
rarefied air of the upper atmosphere.
In the last hundred years man has increased the speed at which he
can travel more than tenfold, but there is no reason to suppose he is
approaching any human limit in speed for, provided that he is pro-
tected from wind pressure by a closed cockpit and that the motion
does not change rapidly in direction, there is no more mechanical stress
on the pilot than if he were sitting on the ground.
If the human body is moving uniformly there is no force acting on
it other than that due to gravity, recognized as weight. But when the
motion changes in either magnitude or direction, large forces come
into play; for example, while launching an airplane by catapult.
During this linear acceleration the pilot has the sensation of being
driven backward against his seat by forces equaling several times his
own weight. This is seen in the retracting of the skin of his face
which bares the teeth like a snarling dog. In this case, the accelera-
tion acts transversely on the body and lasts only a few seconds and in
this direction the pilot can easily withstand many times the accelera-
tion of gravity provided his head and shoulders are well supported.
When a fast-moving airplane changes its direction and turns, air-
plane and pilot are both subjected to very large forces. The phenome-
non known as blacking-out came into prominence in the Schneider
Trophy races; pilots found that in turning at high speed their vision
became blurred and that for a few seconds in the turn they frequently
became blind. This is now a common event in aircraft and is well
understood by fighter pilots.
When an airplane travels in a curved path in turning or pulling out
of a dive a large centrifugal force tends to force the airplane and pilot
away from the center of the circle. The magnitude of this force in-
creases with the square of the speed and decreases as the radius
increases. Subjectively, a pilot experiences a great increase in weight
of all parts of his body as the centrifugal force tries to drive his body
out through the bottom of the airplane. The magnitude of the acceler-
ation acting on the pilot is expressed in terms of g, the force due to
gravity normally acting on the body which causes it to have its normal
weight. Thus in a turn producing 49 or four times the force of grav-
ity, if the pilot’s seat were fixed to a spring balance it would register
four times his normal weight and the pilot and all parts of his body
become extremely heavy. This is seen in the sagging of the soft part
of the face which occurs in a tight turn (pl. 1). A turn at 300 miles
per hour and 1,000 feet radius produces 69, and a pilot in effect weighs
about half a ton and his blood virtually becomes as heavy as molten
iron. The blood is normally being pumped to the pilot’s head by his
HUMAN LIMITS IN FLIGHT—MATTHEWS 275
heart but as its virtual weight increases the heart has difficulty in
maintaining the blood supply to the head. The brain and the eyes can
only function for a few seconds without their normal blood supply
and loss of vision in blacking-out is due to failure of the circulation in
the retina of the eye. If the acceleration is still greater, the whole
blood supply of the brain fails and the pilot becomes unconscious.
Blacking-out is a warning that the blood pressure in the cerebral
arteries is getting low. If the control column is eased forward, the
airplane straightens out, the centrifugal force ceases and within a few

seconds the circulation returns to normal. While this happens in the
head the deficit of blood tends to gravitate to the legs and the phenom-
enon can be regarded as the head losing blood to the feet.
This draining of the blood from the head takes time. The graphs
in figure 1 illustrate the limits of tolerance of acceleration—the greater
the acceleration the less the time that the pilot can retain his sight.
Many measures have been taken to reduce the effect of centrifugal
force on the pilot; much may be done by posture and seating; if the
pilot’s attitude is crouched with his legs raised, the distance through
276 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
which the heart has to raise the blood to his head can be reduced and
the loss of it to his feet is again less if the feet are high. Another
method of lessening the effect of this force which may be mentioned
is to place the pilot in the prone position. The heart and head are
then nearly at the same height and a man in this position can withstand
some 10g, but this posture is a very fatiguing and inconvenient one
for the control of an aircraft, though it is reminiscent of the very
earliest airplanes in which the pilot frequently lay prone. The effect
of posture on blacking-out is shown diagrammatically in figure 2.

Ficure 2.—Effect of posture on the tolerance of acceleration. (Data from Ruff.)
The engineer has produced machines that are so strong and
maneuverable that they can subject the pilot to forces beyond his
tolerance and the useful limit in design for maneuverability at high
speed changes from being an engineering limit to being a human
limit. It would be useless for the aircraft designer to produce an
airplane so strong and maneuverable that it could turn with a
centrifugal acceleration of 20g because the pilot would not be con-
scious to control it under these conditions; the ability to out-turn the
enemy has an important tactical advantage in dog fighting, but to
achieve this it is now necessary to look to the man rather than the
machine. Figure 3 illustrates how the human limit makes it impos-
HUMAN LIMITS IN FLIGHT—MATTHEWS 277
sible for a fast airplane to follow a slow one in a tight turn; both
pilots are subjected to 5g.
The most important stress, however, to which man is subjected in
aircraft is that resulting from the thinness of the air at great alti-
tudes. The air pressure at ground level is 14.7 lb./sq. in. It has
fallen to one-half at 18,000 feet and to only one-fifth, about 234 lb./sq.
in., at 40,000 feet. The effects of altitude on man are those resulting
from the lowered atmospheric pressure.
The disabilities which a man suffers at lowered pressure first came
into prominence on the surface of the earth as “mountain sickness.”

Later the term “balloon sickness” was given to the troubles experi-
enced in high balloon ascents at the beginning of the last century;
long before airplanes had become practical flying machines, the
problems of high altitudes had been encountered because early balloon
ascents carried the balloonists to heights at which the air would
hardly support life and at that time their knowledge of how to over-
come this was lacking.
Plate 2, figure 2, shows the first successful flight when Montgolfier’s
balloon ascended from Versailles in 1788 carrying a sheep, a duck, and
a cock. After the safe return of these animals to earth, Montgolfier
278 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
himself went up some hundreds of feet. Two years later the French
scientist Charles reached a height of 13,000 feet with a hydrogen
balloon.

It is necessary to emphasize the difference between rapid ascent

mountains. In the latter case, weeks are spent at 15,000-18,000 feet to
become acclimatized to the thin air. Great changes occur throughout
the climber’s bodily processes which enable him to live at altitudes
which are fatal to a “sea level” man. Acclimatization is soon lost on
return to ground level, so it is not possible to make much use of this
in flying.
Climbers have reached 28,000 feet on Mount Everest, but in con-
trast to this the first serious high-altitude accident occurred in 1875

loon Zenith. The balloon ascended to about 26,000 feet and the
occupants became unconscious. ‘They became conscious again when
the balloon descended to 20,000 feet but then threw out ballast and
the balloon rapidly ascended to about 28,000 feet. All became un-
conscious and when Tissandier regained consciousness the balloon was
at about 19,000 feet, descending rapidly, but his two companions were
dead. This accident focused a great deal of attention on the
physiological problems of altitude, and to investigate these Paul Bert
constructed a steel chamber from which the air could be removed by
a pump to simulate altitude conditions at ground level. Since then
a great deal of research has been carried out in such decompression

280 § ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
chambers, both on mountains and in aircraft, on the nature of alti-
tude sickness and the ways of overcoming it:
Plate 3, figure 1 shows a modern decompression chamber at an
R. A. F. Medical Service research unit. In this a man can be taken
to a pressure equal to that at 30,000 feet in less than a minute, and it
is capable of producing pressures down to a small fraction of a pound
to the square inch.
Plate 3, figure 2 shows a small type of decompression eine of
which many are in service, which will take six men to any altitude
required so that they can become familiar with their breathing
apparatus and the disasters that may befall them if they do not use
it correctly.
For life, man needs food, water, and air. He can live without food
for weeks, without water for days, but without air he can survive
only a few minutes.
At increasing altitudes, although the proportion of oxygen in the
air remains one-fifth, the density of the mixture becomes less and a
certain pressure of oxygen is essential for living cells to function
normally. At an altitude of 42,000 feet if the lungs are filled with air,
they contain less than one-sixth of the normal quantity of oxygen and
this is insufficient to support life. Much of the Battle of Britain was
carried out in an atmosphere in which a pilot unassisted with breathing
apparatus would be dead in a few minutes. However, long before this
height is reached oxygen lack makes its presence felt in the impaired
intelligence and mental performance of the pilot. As oxygen want
comes on, judgment is lost, gross errors are made, intelligence fails,
muscular control is lost and this is followed by unconsciousness.
Moreover, oxygen want is very insidious because the sufferer is often
almost unaware of it. At 20,000 feet a man without oxygen may do
irrational things; oxygen want resembles drunkenness both in its
symptoms and in that the sufferer is confident that he is normal and
much resents any suggestion to the contrary.
It would clearly be dangerous to send an aircraft up to 25,000 feet
unless it was ensured that the crew were protected from oxygen want.
Much research on the practical protection of flying personnel from the
effects of altitude has been carried out by the R. A. F., particularly by
the Medical Branch which directs research in this very important side
of the pilot’s welfare. The importance of this is emphasized by the
following story of a recent incident which occurred over Ger-
many. A pilot’s breathing apparatus became disconnected and the
pilot thereupon told the crew that he was going to land. He put down
his wheels and tried to land on a cloudbank at about 18,000 feet. He
then told the crew over his intercommunication system that they were
below ground level and he was going to get out, whereupon the navi-
HUMAN LIMITS IN FLIGHT—MATTHEWS 281
gator, ‘realizing what had happened, was in time to stop him from
climbing out of the machine, take over the controls and reconnect the
pilot’s breathing apparatus. It is easy to see that such an incident
might not always have a happy ending. The effects of oxygen want
may often be extremely amusing but clearly there is no place for such
events in the dangerous and difficult work of high-altitude flying.
There are two ways in which altitude effects can be overcome. The
first is to increase the amount of oxygen in the air which the pilot
breathes by mixing oxygen from gas cylinders with it, thus giving the
pilot a mixture rich in oxygen or even pure oxygen to breathe. In this
way when the pressure is one-quarter of an atmosphere at 33,000 feet
if his lungs are filled with pure oxygen he will not suffer from any
symptoms of oxygen lack. To this end the pilot always wears an
oxygen mask, which also carries a microphone for his communication
with the crew or ground.
The second alternative is to increase the amount of oxygen in the
pilot’s lungs by compressing the air in them. Im an engine the loss
of power from oxygen lack is overcome by compressing the thin
air with a supercharger, but it is not possible to supercharge the lungs
so easily as the pressures required would burst them. The pilot must
therefore be completely surrounded by air at increased pressure,
This can be done either with a pressure suit something like a diving
dress or, if the cabin is sealed and made strong enough for it to
withstand a raised air pressure, produced by a pump attached to the
engine. The air around the pilot can then be kept at 14 lb./sq. in.
and the atmosphere he breathes can be exactly like that at ground
level. However, it is clear that for military use such a pressure
cabin is very vulnerable, though for civil use it is the ideal method
in high flying because the passenger is not inconvenienced by a mask
on his face and need not be aware, by any change in the air pressure,
that he has left the ground. Some pressure cabins are in use in civil
airlines in America. The pressure cabin has other advantages over
the oxygen mask besides preventing lack of oxygen. At heights up
to 36,000 feet a man can avoid oxygen lack by breathing pure oxygen,
but above 44,000 feet even breathing pure oxygen he would become
unconscious. Moreover the vapor pressure of blood equals the at-
mospheric pressure at 63,000 feet so if a man could reach this pressure
his blood would boil and his lungs be filled with steam. At heights
above 40,000 feet it becomes necessary not only to breathe pure oxygen
but also to increase the pressure acting on man. Plate 2, figure 1
shows the machine and pressure suit in which Flight Lieutenant
Adam broke the world’s altitude record by reaching 54,000 feet in
1937. The suit. was blown up to some 214 lb./sq. in. pressure and
filled with pure oxygen. In it man could survive even in a vacuum.
282 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Thus the effects of oxygen want can be completely overcome up to
altitudes of some 8 miles by breathing pure oxygen and this is done
in military aircraft of all nations. Above this height pressure must
be applied in addition. In the altitude-record balloon ascents by
Professor Piccard and by the United States Army, closed gondolas
at raised pressure were used.
Figure 6 illustrates the time elapsing between cutting off the oxygen
supply to a man and his becoming unconscious at various heights.
From this it will be realized how quickly a pilot must act should his
oxygen supply fail at high altitudes.

FIGURE 6.—Time between changing from breathing oxygen to

The psysiological abnormalities at altitude are not entirely solved
by breathing oxygen as there are effects on the body at low pressure
in addition to oxygen lack. At ground level the air pressure drives
nitrogen into the blood which dissolves in appreciable quantity. If
now the pressure on the man is rapidly reduced before this nitrogen
can escape,,it will form bubbles in his blood vessels and stop the
circulation. The possibility that something of the sort might occur
in animals at low pressures was envisaged by Robert Boyle in 1670
who placed a viper under a bell-jar and pumped out the air; when
the pressure was reduced he saw a bubble within the eye of the viper.
HUMAN LIMITS IN FLIGHT—MATTHEWS 283
Bubbles forming in the body fluids have long been a difficulty in deep
diving where men have been subjected to much increased pressures of
air. The body fluids then dissolve a large quantity of nitrogen and
if the diver comes to the surface too rapidly it cannot escape from his
lungs in time to prevent bubbles forming and he gets decompression
sickness or “bends” (caisson disease, compressed-air illness), with
severe pain, cramps, occasionally unconsciousness and even death. A
diver can get severe bends coming up from a depth where the pressure
is 4 atmospheres to the surface where it is only 1 atmosphere, but for-
tunately an airman does not get into such serious difficulties if he
goes from ground-level to one-quarter ground-level pressure at 33,000
feet. Bends as they occur in the air are rarely experienced at alti-
tudes below 25,000 feet. They come on slowly and are rarely of a
serious nature. Unconsciousness can result if the warning symptoms
of pain in the joints are neglected. The pains are cured almost
instantaneously if descent is made to about 25,000 feet where the air
pressure compresses the nitrogen bubbles sufficiently to drive them back
into solution in the blood.
Much research has been carried out on men in decompression cham-
bers to find ways of alleviating these effects. One method is to breathe
pure oxygen before ascent, so replacing the nitrogen in the blood with
oxygen. The oxygen is then used up in the tissues before it can form
bubbles. This method has long been used to displace nitrogen from
_ the blood in diving.
There are other disturbances to man with rapid changes of altitude
resulting from the change in air pressure. Behind the ear drum is a
cavity filled with air which communicates through a small canal with
the throat and it is necessary for air to leave and enter it with ascent
and descent lest the ear drum be collapsed. The canal to the throat
will normally open on swallowing and in a dive a pilot clears his ears
almost unconsciously, but should he fail to do so or have severe catarrh,
he may damage his ear drums. Enclosed gas elsewhere in the body, as
in the sinuses surrounding the nose, has to equalize its pressure as the
altitude changes or severe pain may result. Again on ascent the gas
normally present in the intestines expands to a larger and larger vol-
ume as the outside pressure falls when climbing but this is rarely a
serious problem.
Thus the human safety limit in height is some 10,000-16,000 feet
breathing air and 40,000-42,000 feet breathing oxygen; heights much
in excess of the latter are only achieved by enclosing the pilot in an
artificial atmosphere.
But it is clear that starting with fit pilots on the ground much must
be done to keep them efficient in the air and the efficiency of the man
may often be of even greater importance than that of the machine.
284 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
We know that in the Battle of Britain quality in men and machines
overcame weight of numbers and although always greatly outnum-
bered, the R. A. F. by efficiency and courage were able to rout the
Luftwaffe. To maintain that efficiency in the air and at high altitudes
is no mean problem. That it is done is the result of scientific research
during the last 70 years into life at great altitudes and the successful
application of what has been discovered to the particular problems of
the pilot. I should like this lecture to be considered a tribute to all
those scientists from Paul Bert onward and to many officers of the
R. A. F. who have contributed so much to the solution of high-altitude
flying and in particular to those medical officers who have lost their
lives in this war in flying experiments.

TRANS-ARCTIC AVIATION +
By ELMER PLISCHKE, LIEUTENANT (j. g.), U. S. N. R.
Frequently it is wise and profitable to spend a few moments in
speculation on the potentialities of the future. Many improvements
are bound to be occasioned by the necessities of the war, not the least
of which is the impressive development in aviation. The technological
advancements being perfected for war purposes today doubtless will
revolutionize commercial aviation after the termination of hostilities.
One of the most logical results is the linking of the continents by a
network of air routes traversing the Arctic Basin.
Belief in the physical practicability and in the commercial value of
trans-Arctic aviation was first manifested about the time of World
War I, and in 1919, W. Brun, a German, proposed the organizing of
regular flights from the European capitals via Archangel, the Arctic
Basin, and Nome or Unalaska, to either Yokohama, Vancouver, or
San Francisco. A few years later, in 1923, Maj. Gen. Sir Sefton
Brancker, Director of Civil Aviation for Great Britain, enthusiasti-
cally declared in a speech at Sheffield that the carrying of mails from
England to Japan by way of the Arctic was a probability of the next
10 years. In connection with the preparations for the flight of the
dirigible Shenandoah to explore the polar “white spot” between
Alaska and the North Pole, Rear Admiral William A. Moffett, Chief
of the Bureau of Aeronautics of the United States Navy, stated in
1924 that polar air routes connecting England, Japan, Alaska, and
Siberia are possibilities of the near future.
Many writers have since expressed their belief in the future of
trans-Arctic flying. But perhaps the most vocal of these exponents is
the polar explorer and publicist, Vilhjalmur Stefansson, who has been
pointing out the positional importance of the Arctic Basin for the past
20 years. Ona map which has the North Pole as its center, he explains,
the Arctic constitutes a small hub from which the land masses radiate
like spokes of a great wheel, thus lying in the central part of a circular
region enclosed for the most part by northerly extensions of rich and
densely populated modern countries. By the logic of its position, it

therefore should be one of the great transportation crossroads of the
world.
A glance at the globe is sufficient to illustrate the significance of
these statements. Geographers also have designed a so-called “polar
projection,” prepared by laying a geometric plane on the Pole at right
angles to the earth’s axis, and depicting the globe with the North Pole
as the center and with the South Pole as the outer circumference.
Parallels of latitude are ruled off at equal intervals in concentric
circles and meridians of longitude are straight radial lines. As a
result, the northern continents surround the central Arctic Basin and
the Antarctic Continent represents an outer lacy fringe. This projec-
tion is particularly interesting if population density is indicated, for,
with the exception of India and China, the areas of densest population
—between which most aerial communication is likely to develop—le
immediately around the Arctic.

TRANS-ARCTIC FLYING DISTANCES
The distances of air travel between many major locations through-
out the world, especially within the Northern Hemisphere, can be
markedly reduced if trans-Arctic air routes are pursued, as illustrated
by the accompanying tables.
. The distance between New York and Moscow is about 1,000 miles
shorter via the Arctic Basin and its peripheral landed areas. From
Seattle to Calcutta the distance is almost 5,000 miles shorter, while
over 6,000 miles is saved along the polar route from London to Tokyo.
Similarly, the distances between New York and Tokyo and between
San Francisco and either Moscow or London is thousands of miles
shorter via the Arctic.
Further implications of polar air geography are of striking interest.
From North Cape (Norway) it is just as far to Washington, D. C., as
it is to Detroit, Chicago, Des Moines, or Seattle. Chicago is as close
to every capital of Europe as it is to Buenos Aires. Milwaukee, De-
troit, and other great midwestern war production centers, are closer
to Russia by air than are any of the great seaports of the United States.

The saving in mileage and time by following these Arctic airlanes
is considerable. At 300 miles per hour—which is by no means an
impossible rate of speed in the light of recent increases in flying
rates—transports can easily carry their passengers and cargoes be-
tween Berlin and Tokyo, Chicago and Moscow, Montreal and Igarka,
New York and Berlin or Moscow, and San Francisco and London or
Tokyo in less than half the time it takes a crack train to make a
nonstop run from New York to San Francisco at 80 miles an hour.
288 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Planes also can bridge the gap between New York and Chungking,
Minneapolis and Bombay, or New York and Tokyo in considerably
less time than the special express train will require to cross our coun-
try. Finally, at 300 miles per hour, wherever one may happen to be,
no spot on the once wide globe is farther away than 42 flying hours.
Unbeknown to most of us, much already has been done to utilize
and develop these northern routes. Returning from his globe-
girdling tour some months ago, Wendell Willkie flew from China to
the United States, not by way of Australia and Honolulu as might
very well be expected, but rather via Nome (Alaska) and Edmonton
(Alberta). Strict censorship veils the full extent of the action taken
in promoting polar aviation, but we are informed that millions of
dollars have been spent, and that Arctic routes are constantly being
flown. Preparations also are being made by the Government of the
United States to sponsor and protect American interests in postwar
aviation.
ARCTIC FLYING CONDITIONS
But it is frequently believed that flying conditions in the Arctic will
prevent the establishment of dependable commercial traffic. True,
flying conditions in the polar regions are necessarily different in many
respects from what they are in more temperate climates. Neverthe-
less, upon closer analysis it appears that most of the difficulties can
be surmounted.
It is stated that the most ardent exponents of transpolar aviation
consider average flying conditions over the Arctic throughout the
year to be better than they are over the North Atlantic, while the
most pessimistic writers consider them probably worse, but con-
querable. Stefansson, one of the most optimistic of the publicists,
notes that scientists were virtually unanimous by 1930 in agreeing
that Arctic flying in Alaska, to be more specific, is as safe as it is in
Michigan. This, he alleges, is suggested by Pan American Airways
reports to the effect that its flyers generally are as well satisfied with
their work in Alaska as in Brazil, that over half the pilots on its
Alaskan lines prefer January to July, and that, assuming like equip-
ment and ground service, schedules can be maintained through the
midwinter period with an average regularity at least as good as that in
the northeastern part of the United States.
Temperature seems to be no more of a flying problem in the
Arctic than elsewhere. The reason for this is that planes now fly in
temperatures just as severe in Temperate and Torrid Zones while
they are at high altitudes following their established air routes. As
a matter of fact, today effective combat is waged at much greater
heights than was believed possible a few years ago. It is reported
in the press that fighter planes now are regularly flying in the low
TRANS-ARCTIC AVIATION—PLISCHKE 289
temperatures experienced at altitudes of 30,000 and 40,000 feet or
more, and our larger bombers repeatedly encounter temperatures of
25° to 50° F. below zero without considering it a limitation upon their
effectiveness.
In the polar regions there is less diurnal change and less tempera-
ture variation than elsewhere. Flying temperature is said to be
hazardous neither at extreme heat nor at extreme cold, but at an
intermediate range in the vicinity of, and especially just below, the
freezing point of fresh water, for it is at this temperature that ice
forms on the aircraft and weighs it down. Such freezing is not very
troublesome in the Tropics except at high altitudes, and even in the
polar regions icing is less of a problem than it is in the northern half
of the Temperate Zone—where air lines function regularly according
to well-integrated schedules.
Various technological improvements were devised to prevent, or
at least substantially reduce, the formation of an ice covering on
the wings and fuselage of a plane. This is evidenced by the fact
that fighter planes are constantly flying through the lower aerial
zones saturated with the moisture which causes the icing, and perhaps
especially by the fact that effective aerial warfare is being waged
in the foggy and moist atmosphere surrounding the Aleutian Islands
and the shipping lanes to Murmansk. Planes also are used for recon-
naissance purposes at low altitudes by the Soviets along the Northern
Sea Route between our northwestern coasts and the Arctic ports of
the Soviets.
A number of polar explorers, including Richard E. Byrd, who
has flown in both polar regions, contend that polar flying is practi-
cable only at certain times of the year. The spring months, from
March to May,-are said to be best suited for aviation in the Arctic,
because the snow is still hard and smooth and there is less fog than
there is at other times of the year. But this objection seems to be
concerned more with landing and taking off than with flying itself.
and it certainly does not apply to long-range nonstop flying.
At first glance it would seem that a genuine problem of polar avia-
tion is the prevention of oil from freezing and the difficulty of start-
ing the motors in severe temperatures. But oil will not freeze while
the motor is operating and can be preheated before the motor is
started. The problem of starting the motor in sub-zero temperatures
was solved some 15 years ago, when it was learned that fireproof
hoods or special coverings can be used to keep motors warm when
a landing is made, as well as for starting a cold engine. A tube leads
from this hood down to a heater which conducts heat up to the motor,
or powerful warming lamps may be fitted to the motor. In this man-
ner the motor can be preheated to. any temperature, and multi-
290 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
motored planes are fitted with so-called “communicators,” rendering
it possible to warm one motor by the action of another.
The greatest obstacle to Arctic flying is poor visibility due to low- »
lying clouds and fog. In the 46-hour flight of the Worge from King’s
Bay (Spitsbergen) via the North Pole to the northern coast in Alaska,
16 hours—or about 35 percent of the time—were spent in fog. Such
fog is a common occurrence in the polar regions, especially where
warm air, inflowing from lower latitudes over open water, meets cold
air over pack ice or glacier-covered land, as is the case in Arctic areas
during the summer months. Almost all floating ice is said to be ac-
companied by fog, but when the ice is firmly attached to land, as it
is in the wintertime, the atmosphere is relatively free from fog.
Fog therefore seems to be a seasonal problem, but it does appear in
winter in the region of the Bering Sea and the Aleutian Islands, where
the warm Japan Current enters the Arctic, and along the southern
edge of the Arctic pack north of Europe where the warm Gulf Stream
encounters it.
But fog in the Arctic is less dense and lower lying than it is else-
where. Since it seldom rises to a height of over 3,000 feet, planes
can fly over it with little difficulty. It is also thin so that planes
can cruise at low altitudes, and because there are no obstacles like
mountains, except over landed areas such as Greenland, Spitsbergen,
and parts of Alaska and Siberia, the Arctic pilot can see through the
fog and still retain sufficient horizontal vision. When Arctic areas
are properly mapped and a greater number of radio stations are in
operation to give reliable bearings to the polar flyer at all points
along his route, it will no longer be necessary to fly by rivers and other
landmarks, as is now the case.
Opinion seems to be somewhat divided as to whether dependable
regular and emergency landing facilities are available in the polar
regions. On the one hand, it is believed that Arctic waters provide
dangerous landing fields, for, although the water’s surface often
appears clear from above, it may be filled with small lumps of par-
tially submerged ice which can easily wreck a plane as it tries to
land. Because of the movement of’ Arctic ice, moreover, openings
fail to remain open, so that a plane, as it alights upon the water,
may rapidly be hemmed in and crushed by the ice. In the summer
months driftwood also endangers an attempt to land upon the surface
of the water.
As far as landing upon the pack ice is concerned, it is estimated
that perhaps 90 percent of this surface is too rough to be used suc-
cessfully, although there occasionally are some stretches of level
ice upon which a plane may safely alight. But even if the landing
is achieved without mishap, it frequently is more hazardous to take
ee
TRANS-ARCTIC AVIATION—PLISCHKE 291
off from such surfaces, especially because high speeds are now neces-
sary.
Stefansson seems to be somewhat more optimistic concerning nat-
ural Arctic landing facilities. He claims that the Arctic and the
northern third of the Temperate Zone excel the rest of the world in
number and quality of emergency landing fields, noting that there
are millions of lakes which provide suitable spots for landing with
pontoons or skis. These many landing fields, he continues, have given
polar flying a greater safety percentage than exists in other zones,
even in the Tropics. On the Arctic pack ice there are few sections
where good landing fields are more than 20 miles apart, there gener-
ally being a choice of two or more within the gliding range of a plane
if its motors stop at an altitude of a mile or more. In support of this
contention, Stefansson asserts that during a single decade at least 54
such emergency descents were made in every sort of weather, outstand-
ing among which was the third descent of George H. Wilkins, under-
taken at night in a blizzard when he alighted upon the ice pack 100
miles off the northern tip of Alaska. No life was lost in any of these
descents, while the distance covered amounted to over 90,000 miles.
Again, no lives were sacrificed in the search for the Russian flyer Lev-
anevsky in 1937, in which some 50,000 miles were flown.
Contrary points of view are held concerning the suitability of the
ice cap of Greenland as a polar landing field. One group of writers
contends that, despite a prolonged search undertaken by the Danish
Government, there is no known natural landing field in all Greenland.
The ice cap is described as an undulating plain, difficult of access be-
cause it is girdled by a ring of mountains which must be flown over
and which usually constitute one of the greatest hazards of aviation
everywhere. In addition, there are steep, jagged fissures into which
ice pours through the mountains as glaciers. Unless the plane is espe-
cially equipped for a perilous overland journey, an emergency landing
is apt to leave the hapless party exposed to the bitter elements on the
ice cap. Recently two daring aerial rescues of 15 stranded American
Army flyers were disclosed in the press, but both accounts leave no
doubt whatever as to the dangers encountered.
The opposite point of view argues that Greenland’s ice cap is the
world’s largest and finest natural landing field. It is said to form a
continuous and nearly perfect emergency airdrome 1,500 miles long
and up to 600 miles wide. Local gales along its coasts probably can be
offset by selecting nonwindy flying lanes. The use of the southern
part of the island as a route by which military planes are ferried across
the Atlantic seems to justify this opinion, at least in part.
The majority of these hazards attending polar flying may rapidly
be eliminated through the perfection of technological and other im-
292 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
provements. Since most of the obstacles are mechanical, they apply to
flying elsewhere as well. Once they are overcome, the Arctic will
possess the inestimable advantage of shorter distances. Even the
problem of fog can be at least partially overcome by the development
of suitable radio facilities, supplemented with appropriate polar map-
ping, which can itself be done by planes.
As long-distance flying increases in both extent and security, there
is little to gainsay the future of trans-Arctic aviation. Many aerial
feats, which were believed to be visionary but a short time before the
outbreak of World War II, are already looked upon as commonplace.
Who can predict what will be possible within the next decade or two
by a fleet of superplanes, such as the famous 82-ton B-19, with a wing-
spread greater than the height of a 17-story building, with fuel tanks
containing 11,000 gallons of gasoline, and with a range of almost
10,000 miles—which can carry it on a nonstop flight from San Fran-
cisco via New York to London and back to New York, or from Minne-
apolis to Bombay. Current improvements in design and construction
appear to herald fleets of mammoth 100-ton cargo and passenger planes
possessing a size and flying range never dreamed of a few years ago.
TERRITORIAL JURISDICTION
It is such aerial potentialities as these that impel writers and gov-
ernments to turn anxious eyes toward the appropriable landed areas
that remain in the Far North. The successful establishment of trans-
polar aerial communication will necessitate the construction of flying
lanes, landing bases, and radio and meteorological stations. Since the
ice in the Arctic is in constant motion and cannot be relied upon for
the erection of permanent facilities, polar landed territory will become
of supreme importance. The establishment of flying auxiliaries by
the nationals of a state unquestionably will rouse their government to
acquire the territorial jurisdiction necessary to preserve and maintain
these facilities properly. The race for polar territory therefore prom-
ises to be very close at hand.
Under the recognized principles of international law, unpossessed
territory (terra nullius) in the Arctic, as well as elsewhere, can be
acquired juridically only by effective occupation or by prescription.
By occupation is meant the intention to possess the territory in ques-
tion and both the administration of state acts and the exercise of
police power in sufficient strength to protect life and property and
render exceptional a breach of the laws of the occupying state. Pre-
scription means the exercise of state authority over such a length
of time as is necessary under the influence of historical development
to create the general conviction that the present situation is in con-
formity with the international order. Contrary to popular belief,
TRANS-ARCTIC AVIATION—PLISCHKE 293
discovery does not accord a perfect title to new territory, but merely
affords an inchoate title which must be substantiated by effective occu-
pation within a reasonable length of time.
A recent Soviet school of thought has proposed a new theory to
govern the acquisition of polar territory in the Arctic. It is known
as the sector principle, according to which a subjacent polar state
automatically possesses all territory, discovered and undiscovered,
lying to the north of its mainland and within the area bounded by
an extension of its longitudinal extremities to the Pole. Thus, the
Arctic, like a huge pie, is sliced into a small number of sectors, one
accruing to each of the following peripheral states: Norway (Spits-
bergen), Finland, the Soviet Union, the United States (Alaska),
Canada, and Denmark (Greenland and Iceland). But this sector
principle enjoys no validity under international law and has been
recognized only in the municipal law of the Soviet Union. The other
five Arctic states have either refrained from committing themselves
upon the principle, denied its validity by implication, or openly re-
jected it in their state papers. Even the Soviet Government has not
made any attempt to rely upon polar sectorism in its international
affairs.
What, then, is the juridical status of the territory in the Arctic
which is so important for the development of postwar air transport?
In some instances the reply is relatively simple. Thus, the entire
island of Greenland belongs to Denmark, as acknowledged in a series
of declarations made by the United States, Great Britain, France, and
Japan, 1916-1920, and by the Eastern Greenland Arbitration of 1933
between Denmark and Norway which recognized the Eirik Raudes
Land area as belonging to the former. But, according to the recent
announcements by President Franklin Delano Roosevelt and Secre-
tary of State Cordell Hull, the island lies in the Western Hemi-
sphere and therefore comes under the aegis of the Monroe Doctrine,
which prohibits non-American states from acquiring the island. By
and large, the same is true of Iceland, except that it enjoys an unusual
autonomous constitutional position with relation to the Danish
Crown.
Spitsbergen, together with Bear Island, was recognized as Nor-
wegian territory by the Spitsbergen Treaty of February 9, 1920,
following at least a quarter century of dispute involving Germany,
Great Britain, Norway, Russia, Sweden, and the United States. Nor-
way also possesses Jan Mayen Island, having formaily announced the
extension of its jurisdiction over the island on May 8, 1929.
Since 1920 the Soviets have taken a more aggressive course of action
in the Arctic than has any other state. Despite the decree of April
15, 1926, incorporating the sector principle into its municipal law.
294 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
the Government of the U. S. S. R. nevertheless has adopted an active
policy of effective occupation, settlement, and administration for the
islands to the north of its mainland. Thus, a number of important
institutions were organized, especially the All-Union Arctic Institute
for the scientific study of the Arctic, and the Central Administration
of the Northern Sea Route (Glavsevamorput) which exercises eco-
nomic, administrative, and judicial supervision in the Arctic islands.
A scientific method of exploration, annexation, and colonization is
being pursued. In addition, some 200 Arctic scientific radio and
meteorological stations were erected, of which about 75 are located
on the islands. Finally, with the assistance of an elaborate state-
owned system of icebreaker and aerial reconnaissance service, the
difficult Northern Sea Route, which parallels the northern shores of
the Soviet mainland, is regularly traversed by a fleet of public cargo
vessels, the annual shipping amounting to approximately 500,000 tons
prior to the outbreak of hostilities between Germany and the
WS. SOR.
In view of this active display of jurisdictional action on the part
of the Soviet Government, no pretensions have been raised by other
states to territory lying within the limits of the Soviet sectoral decree,
except those entertained by Canada and Norway with respect to
Wrangel Island and Franz Josef Land respectively. But the
U. S. S. R. has in any case established continuous settlements on
Wrangel Island since 1926 and has been sending annual parties to
Franz Josef Land to supply and maintain a network of permanent
stations established there.
No known territory lies to the north of Alaska, and for some years
the United States has raised no serious pretensions to any Arctic
possessions. But considerable interest was at one time centered in
Wrangel Island and a number of smaller islands lying to the north
of the eastern tip of Siberia, including especially Herald, Jeannette,
Henrietta, and Bennett Islands. To the north of Canada, the
American Government displayed some interest in Ellesmere Island
and at least on one occasion refrained from applying to the Canadian
Government for licenses to fly over the Sverdrup Islands (Axel
Heiberg, Amund Ringnes, Ellef Ringnes, and a number of surround-
ing smaller islands), which is required under Canadian law and
which would have acknowledged our recognition of Canadian juris-
diction over these islands. As far as Greenland is concerned, the
American Government always has been actively interested. Upon
the insistence of Secretary of State William H. Seward, a valuable
report was prepared on the island as early as the 1860’s with a view
to possible annexation; in 1910 there was some discussion of the ces-
sion of the island by Denmark to the United States in exchange for
TRANS-ARCTIC AVIATION—PLISCHKE 295
the Philippine Islands, which in turn were to be ceded by the Danish
Government to Germany in return for northern Schleswig; 6 years
later the American Government agreed not to object to an extension
of Danish jurisdiction over the entire island; and, finally, within the
last few years Greenland was acknowledged to constitute a part of the
Western Hemisphere and is therefore subject to our special interests
under the Monroe Doctrine.
The Dominion of Canada claims all the thoi! islands lying to
the north of her mainland. This pretension has not always been
respected, as indicated, so that for the past 15 years a serious effort
has been made-to subject the entire island empire—as embraced within
the jurisdiction of the Northwest Territories and Yukon. Branch
of the Canadian Department of Interior—to-effective state adminis-
tration. This is promoted particularly by the establishment of Royal
Canadian Mounted Police posts on the fringe of the islands area, by
extensive police patrols centered about these posts, by an earnest
attempt to enforce the Canadian legal system in the vast region, and
by the exploits of the Annual Arctic Patrols, which man and supply
the posts. The Dominion, like the Soviet Union, therefore is seeking
to establish an absolute juridical title to the polar territory adjacent
to its mainland.
In this manner, Denmark, Norway, the U. S. S. R., and the
Dominion of Canada possess, or claim to possess, all known territory
within the Arctic Basin. Moreover, under international law, states
enjoy all rights of jurisdiction over the air space superjacent to their
domains, and the air routes which traverse the Arctic will cross
the territory of these four states. If their pretensions to the territory
are acknowledged as valid under law, they will be in a position to
control the major share of the trans-Arctic air lanes. On the other
hand, if their claims are controverted, serious jurisdictional disputes
may arise, as was the case with Spitsbergen, Wrangel Island, and
eastern Greenland.
To avert such controversies, it would seem advisable for the post-
war conference of states to establish a practicable solution for the
international control of the matter. The problem of territorial
jurisdiction should be solved in advance by an international under-
standing through the establishment of specific principles of law,
as was effected at the Berlin Conference of 1884-1885, when the
majority of the Powers recognized the principle of effective occupa-
tion as essential for the juridical acquisition of African coastal lands.
This is a matter of first magnitude and should be resolved before a
host of jealously regarded. vested interests are created. At present,
potential disputes are largely legal in nature and therefore are amen-
able to justiciable solution. But if proprietary interests with exten-
619830—45——20
296 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
sive financial backing are permitted to develop, the matter of resolu-
tion will be infinitely more difficult. Experience has shown beyond
a shadow of doubt that disputes involving important economic and
political interests are far more difficult to solve than are those of a
purely juridical nature.
A series of multilateral air law agreements also will have to be
decided upon, and it might be profitable if an international body
were established to administer such problems as reconnaissance, the
surveying and laying out of transport lanes, the allocation of fran-
chises, the adoption and enforcement of administrative air regula-
tions, and the like. But these suggestions can readily be agreed upon
if the jurisdictional issues are settled.
On a number of occasions it has been proposed that’ remaining
unoccupied polar territory be recognized as belonging to the Society
of States (i.e., as res communis rather than as territory belonging to
no state, res nullius). Then no state could legally acquire a valid
title to the territory and no title of an individual state would be
valid as against the others. Naturally this applies only to island
territory, and does not include those islands already consigned to
a particular state by international agreement—as was the case with
Greenland and Spitsbergen—and those islands which can ‘be con-
sidered as appertaining to a state by virtue of prescriptive rights.
All remaining Arctic island territory should be internationalized,
to be administered either by the League of Nations or its future
counterpart, by some special international administrative agency, or
by some qualified individual state as a mandate.
OUR PETROLEUM RESOURCES?
By WALLACE HB. PRATT
Standard Oil Company (New Jersey)
As “a nation on wheels” we came long ago to rank petroleum, the
source of lubricants and liquid fuels, close to the top of our list of
essential commodities. Recently, as a nation at war utilizing petro-
leum as raw material for indispensable plastics and synthetics, includ-
ing rubber, and even for the TNT of our bombs and high-explosive
shells, we have accorded it a still more important place in our national
economy. Barring the conquest of some new, revolutionary form of
energy, petroleum must continue to be one of America’s paramount
necessities.
What, then, of petroleum for the future? We all realize that the
petroleum resources of the earth are a waning asset; so far as the needs
of mankind are concerned there is no renewal of supply. How large
are the reserves available to us and where are they situated ?
The following quotation is typical of recent press comment on the
subject of our petroleum reserves in the United States: “This nation’s
proved reserves of petroleum now bulk some twenty billion barrels, a
quantity equal to our present peace-time requirements for a period of
about 15 years. Over the last three years our discoveries of new re-
serves have consistently failed to balance our annual consumption.”
These oversimplified figures, though entirely accurate, lend themselves
readily to misinterpretation. Many people conclude from them that
15 years hence we will have no gasoline for our automobiles. They
even fear critical shortages of petroleum products for present war
needs. The misunderstanding might in some degree be dispelled if
the facts were more fully revealed.
The statement quoted leads to the assumption that our 20 billion
barrels of proved reserves in the United States constitute our total
remaining resources in petroleum. Yet in fact our total resources far
exceed our proved reserves. In the first place much petroleum remains
to be discovered in the United States. Less than half the total area
promising for petroleum has been thoroughly explored. In much of

297
298 ANNUAL REPORT SMITHSONIAN INSTIIUTION, 1944
the region already producing, only the upper layers of the petroleum-
bearing rocks have been tapped by the wells so far drilled. Underlying
the beds from which petroleum is now being withdrawn in many of
our great oil fields there remain thousands of feet of rocks, still un-
touched by the drill, which may very well yield petroleum when they
are tested.
Our total past discoveries of petroleum in the United States amount
to about 48 billion barrels. We have explored great areas which most
of us have agreed were of little promise. Yet our past experience has
proved that from 1 to 2 percent of the total area in which we may
reasonably hope to find petroleum actually produces when thoroughly
tested. If our average experience in the area already thoroughly
explored is valid, then thorough exploration of the entire area in the
United States in which it is reasonable to expect to find petroleum
should yield as much additional petroleum as we have already found. °
Moreover, the statement under consideration overlooks the fact that
in addition to the 20 billion barrels of liquid petroleum reserves we
have also in the United States proved reserves of natural gas equiva-
lent in energy content to about 17 billion barrels of petroleum. Nat-
ural gas is really petroleum in another form and with modern tech-
nique is readily convertible into liquid fuels, although the cost of
conversion is still somewhat higher. We should not overlook our
reserves of petroleum in the form of natural gas.
Again the statement ignores the fact that the American petroleum
industry, operating abroad over the last 30 years, has developed addi-
tional petroleum resources in other countries. The remaining proved
reserves in these oil fields easily amount to another 20 billion barrels
or more. These reserves in the hands of American nationals in other
countries have always been available to the American consuming pub-
lic in normal times, and they constitute an important supplementary
proved reserve of petroleum.
The current discussions of the amount of our petroleum reserves
seldom touch on the facts that in the past we have usually recovered
only about 40 percent, or less, of the total volume of petroleum origi-
nally present in our oil fields, and that, on the basis of this past expe-
rience, proved reserves are customarily estimated at about 40 percent
of the total volume of petroleum in the natural reservoirs in which the
estimates apply. Our estimates of reserves include only the petroleum
that we know from experience will flow more or less spontaneously into
the wells that are drilled. The sum of our estimates of proved reserves
plus the petroleum already discovered in this country, some 48 billion
barrels, represents, therefore, a total original volume of about 120
billion barrels. After the estimated volume of our proved reserves
has been completely recovered there will still remain underground in
OUR PETROLEUM RESOURCES—PRATT 299
our depleted oil fields some 70 billion barrels of petroleum. With
improved methods of secondary recovery much of this additional re-
serve is certain to be reduced to possession and utilized over the long
future.
In summary, then, the total proved reserves of petroleum in the oil
fields already discovered by Americans, at home and abroad, are of the
order of 40 billion barrels. Associated with these reserves of liquid
petroleum there are proved reserves of natural gas, or gaseous petro-
leum, equivalent in available energy to an additional 17 billion barrels,
or more, of petroleum. Thus we have a minimum proved reserve of
57 billion barrels of petroleum in the hands of the American petroleum
industry. And after this entire reserve has been exhausted there will
remain in the ground in all the oil fields in the United States from
which our past supplies have been withdrawn an additional 70 billion
barrels or so which we may certainly hope ultimately to reclaim in
part by improved methods of recovery.
As to the decline in the rate of discovery of new oil fields in the
United States, it should be realized that our normal oil-finding effort
has been a war casualty. The failure to discover a larger number of
new oil fields is largely due to the fact that finding oil has been sacri-
ficed to other objectives which we have felt were more important to
the national welfare in time of war. Crude-oil prices were at low
levels when we entered the war. Proved reserves had been increasing,
there was little incentive to risk capital in exploration, a hazardous
venture at best. In the midst of this depressed situation war broke out
and denied to the petroleum industry the critical materials, the man-
power, and the price increases that were essential to stimulate explora-
tion. Except for these restrictions “wildcatting” by the thousands of
small independent enterprises that constitute the mainstay of our oil-
finding industry would have been multiplied and our national discov-
ery rate would certainly have maintained a higher level. Oil finding
is an increasingly difficult undertaking in this country at best, but
during the recent emergency we have simply failed to sustain normal
exploratory activities.
A significant fact which may be deduced from the statement we
have quoted is that our ordinary peacetime consumption of petroleum
in the United States amounts to 450 gallons per capita annually.
Compare this figure with the annual consumption for the average
citizens of the rest of the world, which is 15 gallons; or with 80
gallons for the average citizen of the United Kingdom, or 50 gallons
for the average Russian. We use 30 times as much petroleum per
capita as the rest of the world uses !
Petroleum in the modern world is potential energy. With our
machines it is converted into mechanical work. High standards of
300 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
living result from a large per capita production of goods. The cul-
ture of ancient Greece was founded on the labor of human slaves.
Our high standards of living rest largely upon the mechanical work
done for us by petroleum. The consumption of petroleum in this
country provides us with the work equivalent of more than 4 billion
able-bodied men laboring 8 hours a day, 6 days a week, year in and
year out! In effect our petroleum provides us with an average of
36 strong, able-bodied slaves for every man, woman, and child in the
United States; for the average American family, petroleum does the
work of a staff of 144 servants!
This fortunate condition, America’s abundant supply of petroleum,
is due, we are commonly asked to believe, to the fact that our country
has been blessed with unusually rich natural resources of petroleum.
This is a mistaken idea and to accept it is to ignore an even more
precious heritage with which as a nation we have been blessed.
We have produced more than 60 percent of the petroleum the
world has consumed so far. But this does not mean that we possess
60 percent of the world’s petroleum. Outside the United States ex-
ploration for petroleum has hardly begun. The fact is that most of
the really rich petroleum resources of the earth lie outside our na-
tional boundaries. In comparison with them the quality of our do-
mestic resources appears rather meager. The areas of first-class
promise for petroleum over the earth’s surface aggregate some 6
million square miles; of this total, about 15 percent, or less than 1
million square miles, are included within the boundaries of the United
States. When the petroleum resources of the earth have finally been
fully developed it will probably have been established that less than
15 percent of the total petroleum in the earth’s crust lay beneath the
surface of the United States.
What we in America have been blessed with is a native genius
which, in combination with our political and social concepts, has en-
abled us to explore for petroleum more effectively and to discover
the hidden resources in our country more rapidly than any other
people on earth. Our abundance of petroleum has come to us be-
cause we dug down into the earth all over the land until we found it.
No other nation has made any comparable effort to develope its petro-
leum resources.
To the task of oil finding, in addition to the method of applied
science and a flair for industrial organization, we have brought the
spirit of the pioneer. To an ingenuity which enabled us to design
and operate the ponderous mechanical equipment required to drill
and recover petroleum from wells of unprecedented depth, we have
added the frontiersman’s characteristic risk-taking instinct. Driven
by this instinct, equipped with this machinery, we have gone about
OUR PETROLEUM RESOURCES—PRATT 301
over our country searching for petroleum, setting up hundreds of
independent wildcatting enterprises, drilling thousands of explora-
tory wells every year for a generation. Our geographic frontiers
having been subdued, we have searched out a new frontier in the
vertical dimension, beneath the surface of the earth. The conquest
of this new frontier has brought us our abundance of petroleum and
the high living standards that it sustains.
Every nation has this same vertical frontier but no other nation has
explored it as we have. Over much of the earth, where the natural
obstacles are no more formidable than those we have surmounted,
political and social barriers have prevented the effective development
of petroleum resources. We, too, might have failed had we not en-
joyed our traditional freedoms. Restrictions by the State on the
right to drill exploratory. wells, State ownership of minerals, State
monopoly of rights to explore—any of these restraints would have
gravely handicapped the search for petroleum we have carried out
in the United States. Even the presence of a landed gentry with
unbroken ownership over large areas, in contrast to our widely
divided ownership in small tracts, would have seriously retarded
our efforts. Our methods could not have been employed successfully
in any other than an atmosphere of democratic free enterprise.
If the wells we drill into the earth are successful they usually en-
counter petroleum in the pores and small voids of marine sedimentary
rocks. The petroleum is derived, we believe, from the organic re-
mains of former marine life. Sedimentary rocks are the muds, sands,
and oozes that have accumulated on the floors of seas in past geologic
ages. The hardening of these materials into rock has taken place
slowly under the pressure of the load of later sediments deposited on
top of them.
The search for the petroleum resources of the earth, taking account
of this theory of origin, should be directed to those regions where
in the past marine sediments rich in organic matter have been laid
down in great depth and volume. Marine life, the source of organic
matter, abounds in surface waters near shore, and marine sediments
also are deposited in greatest volume near shore, where the streams
from the adjacent land drop their load of mud and sand. But for
sediments to accumulate to a great depth it is necessary for the sea
floor to subside as fast as the load of sediments is laid down upon it;
otherwise the area fills up and becomes land, and sedimentation
ceases. Hence the search for petroleum turns to the unstable belts of
the earth’s crust where there is delicate, prompt response to any change
in load.
Also it is necessary for the organic matter that results from abun-
dant marine life to be preserved until it sinks to the bottom and is
302 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
actually entombed in the accumulation of sediments. It must not be
destroyed by oxidation or devoured by the marine i peeveneens that
normally feed upon such materials.
There are two common environments pedis recurring in earth
history in which organic matter, falling to the bottom of the sea, is
effectively preserved for burial in the accumulating sediment: seas
into which fine muds pour so rapidly that the stagnant bottom waters
are too foul to permit the presence either of oxygen or of marine
scavengers; and “desiccating” seas, those land-locked bodies of water
all but cut off from the ocean proper, which are subjected to con-
tinuous evaporation so intense that they become highly concentrated
and the various salts nop ye dissolved in sea water are precipitated,
settle out, and accumulate as “evaporites”—limestone, dolomite, salt,
anhydrite, etc.—on the sea floor. ‘The waters of such seas become so
salty that no life and very little oxygen are found in them, except
in the surface layer which is diluted by rainfall and by constant or
periodic inflow of fresh sea water from the adjacent ocean.
When we survey the earth for evidence of conditions in the past
which would best fulfill these specifications for rich and extensive
petroleum resources, our attention is soon drawn to the unstable belts,
covered much of the time by shallow seas, which lies around the mar-
gins of the main continental platforms, between them and the great
oceanic deeps. We note particularly the shallow depressions in the
earth’s crust, which throughout much of the earth’s history have sep-
arated the several continents at their points of closest approach.
The best known of these troughs or depressed segments between the .
continental masses is the region now occupied in part by the Persian
Gulf, the Mediterranean, Red, Black, and Caspian Seas, lying between
the continents of Africa, Europe, and Asia; another conspicuous basin
occupied by land-locked seas is the site of the Gulf of Mexico and the
Caribbean Sea between the continents of North and South America
in the Western Hemisphere; a third is the shallow island-studded sea
lying between the continents of Asia and Australia in the Far East.
Through one geologic cycle after another these intercontinental de-
pressions have been filled with shallow, land-locked seas, teeming with
marine life, into which sediments poured rapidly from the land on all
sides. Frequently, too, these depressions have been the sites of “des-
iccating” seas. The earth’s crust beneath them is unstable or mobile
and yields readily to stresses. Altogether these depressed zones
between the continents seem admirably constituted to serve as natural
reservoirs for the petroleum resources of the earth; and as soon as we
look for petroleum in these regions we find abundant evidence of its
presence.
OUR PETROLEUM RESOURCES—PRATT 303
The earliest historical records of the Near East refer to bitumen,
burning springs, eternal fires, and other phenomena which unmistak-
ably indicate petroleum and natural gas escaping at the surface. In
modern times this region has developed the outstanding petroleum
reserve of the earth, Russia’s greatest oil fields are situated here, as
are the famous oil fields of Iran and Iraq, owned largely by the British.
Arabia, where exploration was undertaken for the first time by Ameri-
cans only a few years ago, has already built up very large proved re-
serves of petroleum, and undoubtedly other important discoveries will
follow. The important oil fields of Egypt and Rumania fall within
this area.
Next to the Near East in importance are the environs of the Gulf of
Mexico and the Caribbean Sea in the Western Hemisphere. Around
the northern shore of the Gulf of Mexico are situated fully one-half
of the total proved reserves of the United States. The tremendous
past production of Mexico, Colombia, and Venezuela has come from
the land fringe along the western and southern margins of this region.
Further exploration in all these countries is certain to yield many new
discoveries. vg
In the shallow depression between the continents of Asia and Aus-
tralia in the Far East are the great oil fields, owned largely by the
British and Dutch, on the large islands of Borneo, Sumatra, Java, and
New Guinea.
If we accept the prewar estimates of the Russians that their proved
reserves of petroleum are of the order of 45 billion barrels, the total
proved reserves for the earth may be safely placed at somewhat more
than 100 billion barrels. Fully 90 percent of these proved reserves
lie in these three intercontinental depressions, and it is generally con-
ceded that these regions also include the best territory by far for
further exploration for petroleum.
There is a fourth great depressed segment of the earth’s crust be-
tween continents which, except for the forward-looking Russians, has
escaped any real consideration so far by the world’s petroleum indus-
try. This region lies between the continents of North America, Eu-
rope, and Asia. It covers the North Pole and is occupied by the Arctic
Sea, a land-locked body of water into which sediments have been
transported by the streams draining three continents throughout much
of geologic time. We are accustomed to think of the waters covering
the North Pole as the Arctic Ocean and our maps commonly designate
them as an ocean, but they are in reality a land-locked sea, a fact long
recognized by the Russians and other European peoples.
Evidences of petroleum are conspicuous at many places along the
coasts which encircle the Arctic Sea. Near Point Barrow in northern-
most Alaska there are copious oil seepages. At Fort Norman, 65°
304 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
north latitude, on the lower Mackenzie River, in northwestern Canada,
a major oil field has recently been developed. On the islands north of
the mainland of western Canada seepages of petroleum from the rocks
at the surface were noted by Stefansson during his Arctic explorations.
At numerous localities marked by surface escapes of petroleum and
natural gas along the Arctic coast of Siberia, over a distance of 3,000
miles, Russian engineers have been engaged for years exploring for
and producing petroleum.
The geological character of the Arctic region and the evidences of
petroleum in the rocks that make up the coasts of the Arctic Sea both
justify the belief that this region will eventually prove to contain some
of the important petroleum resources of the earth.
As long ago as 1888 Edward Orton, a distinguished geologist en-
gaged in a study of the petroleum resources of the State of Ohio
observed: “It is obvious that the total amount of petroleum in the
rocks underlying the surface * * * is large beyond computa-
tion.” Since Orton’s time we have extended our exploration for pe-
troleum much more widely over the earth and, although we have not
as yet even begun to exhaust the possibilities, we have already learned
much to substantiate his conviction that the total amount of petroleum
in the rocks underlying the surface “is large beyond computation.”
Nevertheless the belief persists that our petroleum resources are on
the verge of exhaustion. Even though we have been obliged repeat-
edly to revise upward our previous estimates of their probable volume,
we still fear imminent shortages of petroleum products. Will nothing
we have learned serve to dispel this extreme pessimism ?
Petroleum and coal, our mineral fuels, are fossil sunlight of 2,000
million years of earth history. In our natural resources of coal there
is preserved for us part of the energy of the light which has bathed
the land; in petroleum we recapture some of the energy of the sunlight
which fell upon the adjacent waters. The coal resources of the earth
we have measured, and we can calculate their volume with reasonable
accuracy, a minimum quantity which runs into thousands of billions
of tons—7,500 billion long tons. But the petroleum resources of the
earth, which we cannot as yet measure, we refuse to think of as more
than a few tens of billions of tons—less than one-third of 1 percent of
our proved coal resources. Why do we believe there is so much less
petroleum than coal in the earth? Was the life in the old seas so much
less abundant than that on the land ?
In recent years Parker Trask and others have made extensive inves-
tigations of the sedimentary rocks of the earth. We know that of the
present land surface, some 60 million square miles, more than one-third
is composed of sedimentary rocks; that is to say, an area of 22 million
square miles of the present land surface of the earth has been covered
OUR PETROLEUM RESOURCES—PRATT 305
-by seas at times in the past. Of this total area of former sea floors the
rocks comprising about 6 million square miles are of a general charac-
ter which make them of first-class promise for petroleum; they are
present in great depth and are otherwise favorable for the occurrence
of petroleum. The remaining area of 16 million square miles may
also contain petroleum, but its general character is less promising and
it is rated of secondary importance.
Among other characteristics of sedimentary rocks Trask sought to
determine the organic content. In this research he examined the rocks
which constitute the floors of existing seas as well as those of former
sea floors. The rocks from the floor of the deep ocean proved to contain
but little organic matter. But rocks formed in seas, near shore, were
found to be much higher in organic content. Of the rocks now forming
on the floor of the Black Sea, for example, organic matter constitutes
more than 35 percent by weight. In the rocks from the floors of former
seas Trask found the organic content to range up to 10 percent by
weight, averaging 1.5 percent. Trask estimated the average organic
content of the rocks in the floors of all present seas at 2.5 percent by
weight.
Do these estimates promise enough organic matter to constitute
source material for petroleum resources larger than we customarily
reckon on? Let us confine our attention to the area of sedimentary
rocks of first-class promise for petroleum, some 6 million square miles,
excluding the remaining 16 million square miles entirely. Let us
consider only that portion of the first-class area which is within easy
reach of the oil man’s drill, eliminating all possible resources more
than, say, 7,000 feet beneath the surface, despite the fact that a large
proportion of our present supply of petroleum comes from greater
depths. Let us apply to this restricted portion of the sedimentary
rocks of first-class promise for petroleum only the average organic
content estimated for the floors of all existing seas.
Even on this minimum basis we obtain an estimated quantity of
organic matter so large as to baffle comprehension—a quantity 200
times greater in weight than the total coal resources of the earth!
If only one-half of 1 percent of this organic matter had been con-
verted into petroleum, concentrated and preserved for us in the
natural reservoirs of the earth’s crust, our total petroleum resources
would equal our total coal resources. If only one-tenth of 1 percent
had been so preserved for us, our total petroleum resources would still
be 60 times greater than all the petroleum we have so far discovered:
that is, all our past consumption plus all our proved reserves.
In view of these figures it is not unreasonable to suspect that the
problem we face is not a dearth of petroleum in the earth’s crust so
much as our failure to explore adequately and develop the resources
+
306 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
that are as yet undiscovered. If we now set ourselves to the task .
all over the earth as effectively as we have already done in our coun-
try we should be able to establish tremendous additional reserves. At
any rate, if our total petroleum resources are as limited as we fear they
may be, the explanation does not lie in any original lack of organic
source material in the sedimentary rocks of the earth’s crust. A very
small fraction of the organic matter originally present in the most
promising rocks would have sufficed as raw material for a great deal
more petroleum than we have as yet discovered.

PHILOSOPHICAL IMPLICATIONS OF SOME FACTS OF SCIENCE
By FREDERICK H. KRECKER
Ohio University, Athens, Ohio
Some of you, I am sure, are wondering why a zoologist should
presume to discuss a subject which apparently lies within the domain
of the botanist. Of course to be strictly zoological I might have
used the words formicaries and ants, but no one before me has said,
“One can’t see the formicary for the ants,” and I do not presume to
establish a saying.
I have had considerable experience instructing the general arts
college student, the student who takes zoology as a college require-
ment and without thought of continuing in the field beyond the limits
of the course. Each year at about this season, after all the tumult
and the shouting of instruction have died down, in the wee small
hours of the fading academic year, I take stock and ask myself in
troubled seriousness, “What have I conveyed to my charges?” Facts,
most certainly; but facts without their significance are as food with-
cut vitamins. One is filled but does not thrive. Hence, I query,
have I been content to show to my students merely the trees of fact,
each after each in all their intricacy of detail, or have I also taken
them to a vantage point and shown them the beauty and majesty of
the forest? Have I, in other words, taken full advantage of the
opportunities which President Brown of Denison at our last meet-
ing so eloquently ascribed to the instructors of science. You will
remember that in the course of his remarks he humorously itemized
the tongue-twisting terms that met his gaze as he reviewed the requisi-
tions of his scientific staff. President Brown, however, saw beyond
the terms and the facts they represent. He saw them as a means,
not as ends. Unfortunately, some members of our scientific fra-
ternity, not to mention the man in the street, see only the terms.
Nothing is so revealing, so pathetically revealing, as the desperate
efforts the casual acquaintance makes to find a common ground of

conversation once he discovers you are a zoologist. All too often he
amusingly, likewise tragically, attempts to recall a name—oh, yes,
he says, I studied zoology once. Let me see, what is the name for
oysters and clams? * * * That man has seen the trees. I won-
der whether he was ever shown the woods; whether he was trained in
anything but bare facts. And I wonder too whether, perhaps still
more unfortunately, the significance of significances was ever appre-
ciated by his instructors.
The trees and not the woods loomed large in the remarks made by
a colleague of mine, a purveyor of the humanities, on the occasion of
a round-table discussion between a faculty group and students on the
ever-recurring topic of science and religion. The immediate ques-
tion at issue was the relation of scientific facts to religion. My col-
league was of the opinion that the two could be in no wise related.
By way of illustration he pointed to the facts of meteorology; certain
conditions of temperature, moisture, atmospheric movement we
know result in rain. How can that knowledge possibly have any
connection with religion, he queried. The answer, as we well know,
is simple. This certainty of results which the meteorological facts
represent takes much of the mystery and consequent uncertainty out
of the comings and goings of the weather. To just that extent we
feel secure and in harmony with the powers that ride the storm.
My colleague’s query did double duty. It revealed the barren trees
of both science and religion but the woods of neither. The funda-
mental yearning which the appeal to religion strives to fulfill is
the yearning for security, a yearning which grips all of us. We
tremble before the overpowering uncertainties of enveloping fate,
the unknowable, and strive to achieve a harmonious relationship
through religious experience. The woods, which apparently neither
the scientific nor the religious experiences of my colleague had
revealed to him, were that just as the all-compelling quest manifested
through religion is the quest for security, so the all-embracing fruit
of science is to afford security; the security that frees from the bonds
of uncertainty and superstition and soothes the troubled soul with
the peace that passeth understanding.
This doctrine of security, the teaching that we live in an environ-
ment ordéred by dependable, understandable principles is as old as
science itself, the leit motif that has threaded its guiding way through
scientific thought throughout the ages from the times of the early
Ionian teachers to the present. As F. H. Pike? reminds us in a pub-
lished note within the year, “One great change which occurred in the
period from Thales to Plato was the substitution of a world, perhaps
even a universe, of law for the older world of caprice.” And with it

there was born a new thing, “science,” which as Burnet* so aptly
definies in his survey of Greek philosophy is “thinking about the
world in the Greek way.”
To return to my colleague and, I fear, to many others like him,
what a woeful void there must have been in what he reaped from
science, perhaps also in the guidance offered him by his mentors.
One is moved to paraphrase the biblical interrogation, what doth it
profit a man to gather the facts of science and lose its soul ?
One group of scientific facts, its bare, gaunt trees stripped of their
pleasing foliage, tells us that every particle of matter is attracted
by every other particle in proportion to the product of the masses and
inversely as the square of the intervening distances. These few
words represent a vast number of subsidiary facts and a prodigious
amount of painstaking effort in their formulation. It is known to all
who mull them over that they explain the floating of a mote of dust
to the ground and in the same breath the grand movement of the
planets through space. 1 am wondering, however, how many of those
who have burnt the midnight oil in mastering these facts, how many
of our students, indeed perhaps, how many of their instructors and
how many of our friends in the humanities like my colleague of the
religious discussion have been taken to a mountain top from which
they have been able to see that these same facts have served also as a
guidepost in our quest of the ultimate, in molding man’s interpretation
of his universe, in orienting himself in time and space; that they have
been one of the things which has helped to satisfy man’s wonder, the
awesome wonder that comes over one as he gazes into the depths of a
star-studded winter sky where wonder leads to wonder and one is
moved to breathe the thought, “What is man that thou art mindful
of him?”
As Sir James Jeans * points out, “The law of gravity was important
not so much because it told us why an apple fell to the ground or why
the earth and planets moved around the sun as because it suggested
the whole of Nature was governed by hard and fast laws—in the light
of Newton’s work—Man began to see that he was free to work out
his own destiny without fear of disturbuance from interfering gods,
spirits, or demons.” Or again to partly paraphrase Dampier,’ New-
ton’s reduction of the phenomenon of gravity to mathematical terms,
coupled with the work of Copernicus and Galileo, in one grand sweep
validated terrestrial mechanics in celestial spaces and eliminated with
_ finality the Aristotelian and medieval doctrine that “the heavenly
bodies are divine, incorruptible and different in kind from our im-

perfect world.” The effect was even deeper and struck at the very
roots of religious beliefs in that it was made “impossible any longer
to gaze into heaven just above the sky, and to shudder at the
rumblings of hell beneath the ground.” Consequently, as Brett * com-
ments, “The seat of religious belief was thus moved from the heart
to the head; mysticism was excommunicated by mathematics, * * *
the way was opened for a liberal Christianity which might ultimately
supersede traditional beliefs.”
Incidentally a statement like that is indeed comforting to a zool-
ogist. It lifts from his shoulders some of the burden placed there by
the populace for having undermined ancestral beliefs.
Biology’s central contribution to human thought has been the doc-
trine of organic evolution. This doctrine has brought coherence and
order and significance to a multitude of otherwise apparently discon-
nected facts and theories within the field of biology itself and has
opened up wide vistas of vision in other fields as well. It is undoubt-
edly superfluous to mention this to a scientific assemblage such as this,
but there are scientists, even biologists, who tend to belittle the impor-
tance of evolution in the scheme of instruction. And here again I am
moved to wonder whether we see the woods as we look at the trees;
whether we consider the fact of the evolutionary origin of animals
and plants as an end in itself and the meticulous details of evidence
as ends in themselves or whether we look upon them as means to a
broader end. As ends in themselves they are probably pleasant bed-
time stories, if you like that kind of story. They are facts and add
to one’s store of such things, if your hobby is making a collection. If
that is the spirit in which one presents the matter embellished for good
measure with much precise detail, I fear that in the words of the phi-
losopher, Irwin Edman, once applied to some of the humanities, it
will be shortly “dying of anemia, of archeological hardening of the
arteries and will become a corpse handled conscientiously by solemn
morticians.”
As means to an end the formulation of the doctrine of organic evo-
lution, like the formulation of the principles of gravity, has served as
the factual basis for a reorientation of human conceptions. If Newton
paved the way for a liberalized Christianity, Darwin has paved the
way for a liberalized sociopolitical outlook. The doctrine of organic
evolution has once and for all destroyed the concept of the immutabil-
ity of human institutions as well as of animal bodies. It has destroyed
finality. If man as an animal is the product of change, his institution,
the state, as a sociopolitical organization is not immutable. What
served the purposes of our fathers may not of necessity serve ours.
And so also have we been conditioned to discard the concept of absolu-

tism in the field of economics. With changing times come changing
economic principles.
Organic evolution with its handmaiden, natural selection, has de-
stroyed the sociological equalitarianism of the French Revolution.
All men may be equal before the law; they are not equal before the bar
of life. Gone, too, is the categorical dictum’as a basis for morality
and in its place has come racial experience, those standards which have
survival value for the race. Morality in this light comes to mean
allegiance to that code which will enable one’s countrymen to live and
to have life more abundantly. For those who may mourn the passing
of the categorical standard, let me say that racial survival is a far
more exacting standard than one which, perchance, permits of com-
pensation by doing penance. The youthful monkey merrily swinging
from limb to limb who misjudges his mark gets no second chance and
leaves no descendants. It is, indeed, easier for a camel to pass through
the needle’s eye than to cheat the laws of life.
There is tonight no time, even if this could be considered an appro-
priate place, in which to trace all the ramifications of our racial expe-
rience as a standard by which we may order our lives. However, I
should like to enlarge upon one phase of our experience which does
appear to be peculiarly applicable to the present state of world affairs.
Julian Huxley,’ in discussing man’s achievements points out, as have
others, that “the next step of greater control must be over man him-
self * * * through (among other methods) doing away with
nationalistic drives and superimposing an international form of gov-
ernment on the world.” To a biologist there straightway comes the
question, what evidence have we that cooperation is any more success-
ful than isolation as a biological method? Has not the arch isolation-
ist, Amoeba, survived for millions of years and have not thousands of
other rugged individualists been successful among the animal hordes?
That interrogation immediately poses another—what is success? And
to answer one must differentiate between survival and mastery. An
animal, all of us, may survive through a variety of devious subterfuges
and expedients, the common mark of which is that they entail sub-
servience. However, success in fullest measure is mastery over condi-
tions. If organic evolution has any significance it is the story of how
living material has, through the cooperative actions of its subdivided
units, approached, if it has not yet attained, mastery.
Tam fully aware of the fact that organic evolution does not of neces-
sity proceed along a straight-line principle, that life has followed a
thousand and one devious pathways and on occasion has even retro-
gressed ; but the fact remains, nevertheless, that at each level on which
™Man stands alone, 1940.

there has been a closer approach to mastery that approach has been
accompanied by a greater division of labor and a closer coordination
of the constituent units until in man, the master, they have become
woven into an intricate pattern of cooperating parts. At the opposite
extreme lies an ineffectual, single-celled droplet of living material
exemplified by Amoeba. Organic evolution is thus history, as much a
part of our history as is the history of the written word, and as such,
in fulfilling one of its functions, it points out the road we have trod
and lights the way that les ahead.
I am a zoologist, but for a moment I should like to turn Tey
that man who has been termed by Schlegel a prophet looking back-
ward, and as such a prophet refresh your memories by briefly tracing
the steps of this story as others have done before me.
It can begin with Amoeba, a creature which epitomizes individual-
ism. Not even in the commonly shared function of reproduction is it
dependent upon another for assistance. A thousand and one changes
have been rung on this isolationist-individualist theme among its fellow
protozoans, each change having brought survival but no shred of
mastery.
One of the early mutations leading out of the protozoan doldrums
was that which resulted in causing proliferating cells to remain clus-
tered together, and as such clusters to cooperate in the form of tubular
units; a condition exemplified in varying degrees by the Porifera and
the Coelenterata. The rewards were those that come from numbers |
and elementary divisions of function. This condition was followed
by an innovation which resulted in dense, compact and solid masses
of cells being able to exist as a single unit exemplified by our friends
and tormentors, the flatworms. This state of affairs was accompanied
by greater diversification in the constituent units and preeminently
by rectilinear locomotion.
The next steps—three of them—in this mutating series were par-
ticularly significant ; the development of distance receptors, the device
which produced essentially compound animals, and the accompanying
delegation of authority to subcenters which thus made possible the
rapid and efficient control so characteristic of the metameric groups.
Metamerism is as far as life has gone in the way of physically com-
pounding units. The compounding has continued but on the psycho-
logical level, or social level if you wish. If we are to consider
psychological reactions as a specialized manifestation of physiological
states, the continued compounding which we term our social organiza-
tion is fully as much a physiological process as were the physical
unions just outlined and as such must be considered a direct con-
tinuation of this compounding tendency, a continuation made pos-
sible by the development of distance receptors.
WOODS AND TREES—KRECKER 313
In saying this, I am mindful of those who maintain that social
organization is not comparable to corporate organization. I am in-
clined to think the difference is not so much a matter of principle
as of means. In the one case the constituent units have been held to-
gether by bonds of physical contact, in the other they have been as
firmly held by the influence of distance receptors. Emerson,® the
ecologist, has recently expressed the view that, “Regardless of how
one interprets the unity of the more complex human societies, the
human family, and other family systems, are real cooperative, supra-
organismic entities. * * * Society is merely a manifestation of
fundamental life attributes which are shared with other biological
systems (e. g., multicellular organisms) and the division between the
social and the non-social is not sharp.” Jennings® goes further and
points out that there is much to be said in favor of the conclusion
that “mankind is a single great organism temporarily divided into
pieces—the individuals.” Through this device the essential benefits
of physical union are retained and become enriched by the advantages
to be derived from mobile units. The study of organic evolution is,
indeed, from one standpoint essentially a study in populations.
Much can be said in support of the conclusion emerging from such
a study, that in its animal phases at least unitary masses of proto-
‘plasm, whether these units be cells or bodies, under similar conditions
follow essentially similar principles of group organization.
The social organization of the corporate population has, as you
know, followed along two lines, the one illustrated by certain insects,
the other by man. Among insects the culmination is reached by the
ants and the termites, those individually defenseless creatures and
toothsome morsels for many a foe which have through cooperation
lived from the Tropics to the borders of the Arctic.
Our own social structure is an even more intricate and widespread
culmination of increasingly interdependent component units the
progress of which has followed one unswerving path marked by the
milestones of free cells, tissues, organs, organ systems, compound
organisms, then families, tribes, kingdoms, empires, major alliances,
and still it holds its course into the future. Faintly outlined as yet
but apparently on our course lies some type of world union. This
last prophecy may be branded an ultra-utopian fancy, but it must
not be thought that the pyramiding of units I have just traced,
whether in the field of physical union or sociopolitical associations,
came without a struggle, without false starts that led up blind alleys
or ended in stark failure.

314 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
For those who may be faint-hearted, the fact to be kept in mind is
that with all the difficulties that beset the way, union was eventually
accomplished, that with each union, with each sacrifice of self, with
each restriction of liberty, there has been a stride toward greater mas-
tery, toward a fuller, more abundant life for the whole. At one ex-
treme is individualism, represented by Amoeba, beholden by neither
jot nor tittle to anyone, groveling withal in the slime and swept hither
and yon by every whim of nature. At the other extreme are millions
of interdependent cells united in the form of men who, in turn, through
their combined efforts have overcome the sufferings of famine, the
scourge of pestilence, the barriers of distance, the mysteries of the air,
yes, even the intricacies of creative synthesis. Optimism for the future
is well expressed in the words of the paleontologist, Lull,° who writes,
“The great heart of nature beats, its throbbing stimulates the pulse of
life, and not until that heart is stilled forever will the rhythmic tide
of progress cease to flow.”
Among the social insects the price paid to the group for the benefits
of cooperative action is that the individual be born to a class and have
stamped upon him unalterably the form of his station in life—worker,
soldier, king or queen—there to remain toiling dutifully without will
or choice that the group may survive. That is strait-jacketed, in-
flexible efficiency, not inviting to those of us outside the pale of Nazi
or Fascist rule. It has, moreover, fallen short of control, probably
because its morphological inflexibility is paralleled by inflexibility of
nervous reaction.
There is no gainsaying that one of the most patent of biological prin-
ciples requires that when individual and species conflict, it is the
individual that must give way even to the extreme of life itself. For
us the demands of society are indeed becoming more and more exact-
ing; we are individually being held to a closer and closer accounting.
There is ever-increasing regimentation. But we of the vertebrate line
are fortunate in that we belong to a type of social organization which
permits its members the opportunity of realizing their responsibility
to the group and of doing their duty voluntarily and without compul-
sion. If we but will, therein lies our avenue of escape from the fate of
an enforced regimentation analogous to that of the insects.
The responsibility which rests upon us individually arises from the
division of labor inherent in society. Each sequence in the evolution-
ary progress of living material from microscopic unit to dominating
mass involved more and more detailed division of labor and with each
advance there came increasing responsibility. For instance, in an
unspecialized body like that of a sponge the entire body, as you well
know, can be taken apart cell by cell and then the whole mass or any
2 R. S. Lull, Organic evolution, 1929.
WOODS AND TREES—KRECKER 315
portion of it can again take on the form and function of a sponge.
Here, it matters little whether any one or a group of cells fail. At the
opposite extreme in man, the loss of an islet of cells in the pancreas
means death. Clearly specialization and responsibility go hand in
hand.
The inexorable demands of nature that each do his duty to his kind
need not of necessity mean that before us lies a future in which we
shall be slaves to the State, Nazi-fashion. A slave performs his duty
without choice, has no voice in his fate. Before us lies the opportunity
to both exercise our choice and discharge our duty. If, however, we
do not so choose, we shall have responsibility and no freedom, no
chance to direct our fate. There are even now those among us who
would impose the prototype of insect rigidity upon our form of social
organization. Its most extreme exponents are the followers of Nazi
philosophy. Rauschning™ reports Hitler as declaring, “There will
be a master class * * * also a new middle class * * * and
the great mass of the eternally disfranchized. Beneath them still will
be * * * the modern slave class) * * * Universal education
is the most corroding and disintegrating poison that liberalism has
ever invented for its own destruction.” Carrel? has expressed some-
what similar views, as for instance, * * * “The democratic prin-
ciple has contributed to the collapse of civilization in opposing the
development of an elite. * * * modern civilization is incapable
of producing people endowed with imagination, intelligence and cour-
age. * * * the equality of their (man’s) rights is unequal.”
It is true that there are biological differences among us which cause
difficulties in a democratic state, but gene distribution is such that few
are wholly of inferior quality and few, if any, of wholly superior stuff.
The mechanism of transmission and interaction of genes further com-
plicates the picture. And who is to differentiate what is good or how?
As Jennings suggests, “One of the greatest difficulties in the way of
effective human action lies in the lack of agreement as to the end to be
attained. * * * perhaps the greatest difficulty of all lies in the
lack of agreement as to the individuals or groups that should benefit
by the action to be taken.”
The course upon which the physically undifferentiated and mobile
fabric of the vertebrate social organization is set does not of necessity
demand a society strait-laced and closely regimented in which free-
dom of action is surrendered. It does demand and will exact the
surrender of action for self alone. It does place upon us unalterably
responsibility to our fellow men. The failure on the part of many of
us, most of us I fear, to realize this fact has been an important source
4 The voice of destruction.

316 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
of our present unrest. With a sense of allegiance to the group in the
spirit of that larger self-interest which realizes that the greatest good
for the individual is inextricably bound up with the good of the
group, there need be no fear of enforced regimentation. Unlike the
strait-jacketed insect civilization, such realization of individual re-
sponsibility permits us freedom to pass from stratum to stratum as
the cast of the genes may decide, and leaves us the stimulus of in-
dividual initiative. The specializations of society without a sense of
responsibility lead to the limited privilege of an unbridled, cancerous
growth; specialization with a sense of the common good leads to the
harmony of a well-ordered body.
As I come to the end of my remarks let me mention once again
my thoughts at the close of the academic year, my interest in the trees
of fact and the woods of significance. I have, as you see, directed
your attention to but a few examples. First among them was the
very soul of science, the sense of security which scientific facts con-
vey. Second was the influence of what may appear to be purely phys-
ical principles upon the liberation of man from the bonds of religious
ignorance; third, the significance of the facts of evolution as a guid-
ing light upon our way and finally the significance of the individual’s
obligation to the group. I have discussed them because with all the
inimediately practical applications of fact that can be made, which
are truly many and important, such applications alone are not suf-
ficient. The instructor in science has not completely fulfilled his re-
sponsibility to those who come to him for guidance unless he has
pointed out the wider significances. These broader applications
which carry us into the realm of ideas are required to satisfy fully
that age-long quest which Sir William Dampier has so richly clothed
in these words:
At first men try with magic But Nature smiles—a Sphinx-like
charm smile—
To fertilize the earth, Watching their little day
To keep their flocks and herds She waits in patience for a
from harm
And bring new young to birth.
Then to capricious gods they turn
To save from fire or flood;
Their smoking sacrifices burn
On altars red with blood.
Next bold philosopher and sage
A settled plan decree,
And prove by thought or sacred
page
What Nature ought to be.
while—
Their plans dissolve away.
Then come those humbler men of
heart
With no completed scheme,
Content to play a modest part,
To test, observe, and dream.
Till out of chaos come in sight
Clear fragments of a Whole;
Man, learning Nature’s ways
aright,
Obeying, can control.
BIOLOGY AND MEDICINE’
By Asa CRAWFORD CHANDLER
Professor of Biology, The Rice Institute
My subject this afternoon is “Biology and Medicine,” but I think
a more accurate wording would be “Medicine and Other Phases of
Biology,” for to my mind medicine is a branch of biology. Webster’s
Dictionary defines medicine as the science and art dealing with the
prevention, cure, or alleviation of disease. Biology is the science of
life. Disease might well be defined as life out of balance, and is in a
strict sense a biological process. Whether it be an attack by micro-
organisms, or improper functioning of glands, or congenital mis-
formation or maladjustment, or injury by poison or bullets, disease
processes are in the last analysis nothing more than cells, tissues,
or organs that have suffered injury and so not only fail to perform
their normal functions but in most cases interfere with the normal
functions of other parts, more often than not of the entire body.
Of the two great divisions of medicine dealing respectively with
treatment and with prevention, the former is much the older. It is
far easier to observe the effects of treatment on a person suffering
from a malady than it is to understand why someone else escaped
it. Some knowledge of curative or alleviative medicine was possessed
by our cave-dwelling ancestors; in fact, it is instinctive in many
lower animals. It gradually grew up as a sort of folklore from a
slow process of trial and error, added to the instinctive knowledge ac-
quired from prehuman ancestors.
With the growth of belief in the supernatural, by which man satis-
fied his developing desire to explain things, medicine became largely
theological. Priests and physicians were one. They conceived disease
as the work of devils, gods, or spirits which had to be appeased by
sacrifices, confused or circumvented by charms or incantations, evicted
by emetics, cathartics, or bloodletting, or enticed to escape by means
of holes in the skull, nasty medicine, or other devices. It is since the
days of our Pilgrim Fathers that we have learned that it is more effec-
tive to control typhoid and cholera by boiling water than by boiling
witches.
Although belief in the instrumentality of demons and witches in
causing disease persisted for a long time, since Hippocrates more en-

lightened individuals have recognized at least some kinds of disease as
natural processes. From that time to the present medicine has been
primarily biological instead of theological or metaphysical. Some of
the original ideas were, as would be expected, very far astray; for
example, the theory that Hippocrates inaugurated and Galen ex-
panded that proper proportions and relations of four humors of the
body were responsible for health or disease. According to this theory
people were sanguine, phlegmatic, choleric, or melancholic in tempera-
ment depending upon which of the four humors predominated. Erro-
neous as it was, this theory was a long step forward in that it focused
attention on natural instead of supernatural causes, and on caring for
the patient instead of appeasing devils.
Hippocrates was also an exponent of the great biological principle
that nature is the greatest physician of all. Left alone, an organism
attempts to repair damages to its parts, to adjust itself to any unbal-
ance in structure or function that has been entailed, and to fight off
attacks by parasites. The role of the physician is to aid the organism
in these attempts. In many cases this involves nothing more than
augmentation or speeding up of natural biological processes that the
organism itself would employ, such as stimulation of immunity, sup-
ply of additional antibodies, provision of new tissue or fluid in the
form of grafts or blood transfusions, supply of abundant vitamins,
regulation of hormones, removal of unhealthy tissue, and protection
against invasion by micro-organisms. In some cases it involves meth-
ods which are entirely foreign to the natural processes of the animal
body, but which aid and abet these processes, such as the use of stimu- ~
lants, anesthetics, specific drugs, X-rays, radium, or heat.
The speeding up of natural processes of repair or adaptation is
applied biology. It involves a thorough knowledge of the normal
biology of the human body—its anatomy and all phases of its physi-
ology. Strangely enough, even knowledge of the gross anatomy of
the human body was extremely sketchy and mostly wrong up to the
middle of the sixteenth century.
Galen, of the second century A. D., was the father of anatomy for
years, but he was a very poor father and his offspring was a very
hodgepodge anatomy, arrived at from observations on the inner
workings of monkeys, pigs, dogs, and cattle. For over a thousand
years man was supposed to have a segmented breastbone like a
monkey, a liver divided into as many lobes as a pig’s, a uterus with
two horns like a dog’s, a hipbone flared like that of an ox, and a heart
with pores between the right and left ventricles. If in the meantime
any errors were discovered in Galen’s descriptions the fault was al-
ways thought to be either with the patient or with the later observer.
When Vesalius, in the sixteenth century, showed that man’s hipbones
certainly were not flared as Galen described them, it was thought
BIOLOGY AND MEDICINE—CHANDLER 319
that they had undergone a change in the intervening centuries due
to the habit of wearing tight trousers.
The study of anatomy was retarded greatly by religious and civic
taboos on dissection of human bodies, but Vesalius spirited skeletons
from beneath gallows and was not above occasional clandestine disin-
terments. He made important contributions to human anatomy, and
did much to start other physicians consulting nature instead of Galen.
Vesalius even reached the threshold of the discovery of the circulation
of the blood, but this great milestone in the history of medicine was
planted by Harvey in the seventeenth century. Probably no other
single physiological discovery has had such profound consequences.
What a superlative.age that was, to produce a Harvey, a Shakespeare,
and a Galileo!
In the eighteenth century advances were more rapid. It was in
that century that another great Englishman, John Hunter, discovered
that if arteries are tied off the blood will find and develop new chan-
nels. Prior to that discovery aneurisms, which were distressingly
common, were treated, if at all, by amputation of limbs. John Hunter
also learned some of the tricks of grafting skin and bones.
In the next century, the nineteenth, two other fundamental bio-
logical principles—the cellular structure of bodies, and evolution—
came to light. Both of these ideas contribute so much to our knowl-
_ edge of the human body and how it works that a full evaluation of
their significance in medicine would be almost impossible.
Even with all these advances in anatomy and physiology, nobody
up to the middle of the seventeenth century had any good idea what
disease was or whence it came. An important forward step was made
in 1687 when two Italian scientists, Bonomo and Cestoni, showed that
scabies was a disease caused by tiny mites burrowing and reproducing
in the skin, and was spread by transmission of the mites. This was the
first demonstration of a specific cause for a disease, and the first ex-
planation of its spread, and was a clean break from the divine,
humoral, or other ancient theories of the spontaneous origin of disease.
A few pioneering minds, a century or two ahead of their times,
propounded theories of contagion, and spread of disease by dessemina-
tion of poisonous particles or gases, or even by invisible living organ-
isms, but there was no experimental evidence, and these precocious
ideas fell on barren ground. A true understanding of infectious dis-
ease had to wait for the discovery of micro-organisms and some knowl-
edge of their nature.
Leeuwenhoek, a Dutch lens grinder of the seventeenth century,
who invented a compound microscope capable of bringing bacteria
within the range of visibility, is sometimes called the father of bac-
teriology, but I think he might more properly be called its midwife.
He was one of the greatest explorers of all time. Magellan and
320 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Columbus are credited with discovering continents, but Leeuwenhoek
opened the door to an entire new world. Wherever he looked—in
soil, water, food, excretions, or decaying materials—he discovered
a host of micro-organisms that nobody had ever seen before or even
suspected of existing. Modern explorers with electron microscopes
are having a great time too, but their discoveries of molecules and
viruses and of the minute anatomy of bacteria is hardly to be com-
pared with the new world that Leeuwenhoek found under his
microscope.
But I do not think that knowledge of the existence of insects makes
an entomologist, or knowledge of the existence of stars an astronomer,
so I hesitate to consider Leeuwenhoek the father of bacteriology.
That honor, I think, should go to Pasteur who, within the lifetime
of my parents, made bacteriology a science. He did it by providing
final proof that germs, like all other forms of life, require parents,
and come only from pre-existing germs. As long as it was thought
that germs developed spontaneously from decomposing materials the
bacteriologist was in as hopeless a position scientifically as a mathe-
matician would be if the sum of two and two varied with the weather.
From the standpoint of the control and prevention of disease this
was undoubtedly the most momentous discovery ever made by man,
for it alone provided a solid foundation for practically all our public
health work. On it rests all our theory and practice concerning
contagion and infection, quarantine, sterilization, antisepsis, aseptic
surgery, purification of water, pasteurization of milk, and almost
everything else on which modern practices of public health and hygiene
are based. Pasteur is rightly revered for his great contribution in
proving the germ theory of disease, but this would have been of little
value or significance without the final abolition of the idea of spon-
taneous generation, which for a long time extended even to maggots
and mice.
Pasteur’s fundamental discoveries led almost at once to practical
applications. Lister in London was quick to apply them to surgery,
and by very generous application of carbolic acid to himself, the pa-
tient, the bedclothes, the air, and even the floor, be brought about a
very considerable reduction in the mortality from operations, which
had previously been about 45 percent even in his expert hands.
During the eighteenth century Europe suffered from great epi-
demics of childbed fever—at one time it got so bad that in Lombardy
it was said that for a year not one woman lived after bearing a child.
Europe’s lying-in hospitals for destitute mothers were humane in
spirit only; in reality they were death traps. Oliver Wendell Holmes
proclaimed childbirth fever an infectious disease, carried from patient
to patient by physicians and midwives. Many physicians were in-
censed at the imputation that their hands were not clean, and Holmes’s
BIOLOGY AND MEDICINE—CHANDLER 321
ideas didn’t make much headway. It was Semmelweis of Vienna who
finally dealt the death blow to childbed fever as an epidemic occur-
rence, and proved that even an eminent gentleman’s hands are not
always clean. It is within the memory of many in this audience that
aseptic surgery finally supplanted Lister’s heroic antiseptic measures,
and that surgeons began paying more attention to washing their hands
before an operation than after it.
Some 20 years after Pasteur’s demonstrations of the germ cause of
disease and the final putting to rest of the theory of spontaneous gen-
eration, Robert Koch developed technical methods that made possible
the easy isolation and study of particular kinds of germs, and then
discovery followed discovery with almost incredible rapidity. In the
short space of 15 or 20 years the causes of the majority of infectious
diseases of man and animals were isolated and studied. The elusive
and rather mysterious agents of disease that we call viruses, however,
had to wait much longer for biologists and chemists to pry into their
private affairs, and it is only now that very much progress is being
made.
An infectious disease is, however, an extremely complicated phe-
nomenon. The interaction of a parasite and its host is not a static
thing like the interaction of one chemical with another, capable of
simple description, and following a well-defined course. We may be
too prone to think, because we know what organism causes a disease
and something about its biology, that we understand the disease it
causes. Nothing could be farther from the truth. We are dealing
with the interaction of two organisms both of which are capable of
an amazing degree of adaptation to changing conditions. Every
change or adaptation in one entails further adaptations in the other.
A disease may be compared with an organism—it is born, it grows, it
adapts itself to environment, and it finally dies. During its life it is
influenced by a host of environmental factors which may profoundly
alter its course.
An infectious disease depends on the presence of a specific invading
organism, but this may be only one of the necessary requisites. In
almost every epidemic the number of healthy carriers—people who
temporarily acquire a colony of the germs but show no evidence of
disease—far exceeds the number of cases. In an epidemic of cerebro-
spinal meningitis healthy carriers of the organism that we say causes
it may outnumber the clinical cases 20 to 1. In most epidemics of
such diseases as diphtheria, whooping cough, dysentery, and even
cholera, the ratio is from 5 or 10 to 1.
If disease develops in only one-fifth to one-twentieth of the people
reached by a’particular pathogenic germ, it is evident that there are
other factors playing very important roles in its production. Among
these are a proper balance of the glands of internal secretion, good
322 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
nutrition, especially with respect to vitamins, and the development
of specific immunity or resistance. There can be no doubt that these
same factors play a large part in determining the course and outcome
of a disease after it has gotten a start. A physician, then, if he is to
make the most of his effort to help in suppressing disease, must be far
more than a dispenser of medicine. He must, indeed, be familiar with
more phases of biology than are most biologists. He must understand
anatomy, histology, general physiology, endocrinology, embryology,
psychology, nutrition, immunology, and even genetics in order to have
a proper understanding of his patient, and he must be a bacteriologist
or parasitologist to understand the capabilities and vulnerabilities of
the invading organism.
Some relations of heredity and genetics to disease have been known
for a long time, but more progress has been made in genetic control of
disease in plants and even in domestic animals than in man. Effects
of genetic constitution of human beings on the course of disease and
development of resistance are still very little understood, and still less
is known about effects of genetic constitution of pathogenic organisms
and means of altering it. Herein lies an almost untouched field with
vast possibilities for the future.
Experimental breeding of mice has resulted in decreasing torte
from a particular disease from 82 to 24 percent in six generations, and
to 8 percent over a period of years. In six generations of chickens
mortality from fowl typhoid decreased from 85 to 10 percent. Recent
studies indicate that alterations in genetic constitution comparable to
mutations in insects and plants occur also in bacteria and even in
viruses. In a period of a few hours many kinds of bacteria and viruses
may reproduce in such numbers that if their rate of mutation is com-
parable with that thought true for fruitflies, each gene the bacteria
possesses should mutate at least once. With even slightly favorable
selection, replacement of the parent population by mutants is possible
in short periods of time.
Viruses have many characteristics of genes, differing principally in
their ability to move from cell to cell. There is evidence that the
mutation of viruses is comparable with mutation of genes. The de-
velopment of relatively nonpathogenic varieties of viruses or bacteria
is the real basis for the production of effective vaccines against such
diseases as smallpox and yellow fever, and probably for the rise and
fall of epidemics of cholera and diphtheria. It has recently been
discovered that the virus of infantile paralysis genetically altered by
mouse adaptation, when mixed with the parent virus, has great power
to protect monkeys from paralysis. What causes the protection is not
yet known, but the result of this basic discovery may be very far
reaching.
BIOLOGY AND MEDICINE—CHANDLER 323
Concomitant with development of knowledge of causes of infectious
diseases, immunology was beginning to make its contributions to the
cure and prevention of disease. You are all familiar with Jenner’s
discovery in 1798 of the protective value of cowpox inoculation against
smallpox. As the result of that there is probably no one in this audi-
ence with a pockmarked face, whereas in Jenner’s day certainly one in
four of you would have been so marked if indeed you were alive at all.
Jenner, however, had no notion of how his method worked; he merely
observed that it did, and risked the ridicule of the medical world by
saying so, and the life of his own son by testing it.
Many decades later Pasteur, making the most of an accidental obser-
vation, laid a foundation for modern immunology by showing that
agents of disease can be attenuated by various means to a point where
they are no longer capable of producing serious disease, but still possess
the power of stimulating immunity comparable with that produced by
recovery from a real attack. Just as bacteriology opened the gates to
knowledge of the causes and means of transmission of infectious dis-
eases, so the birth of immunology opened the way to knowledge of
nature’s principal means of combatting them.
The contributions of immunology to the cure and prevention of dis-
ease are so numerous that [can mention butafew. Asaidsin diagnosis
I may mention the tuberculin test for tuberculosis in cattle and man;
the Shick test for susceptibility to diphtheria; the Dick test for sus-
ceptibility to scarlet fever; the scratch test for allergies to pollens,
foods, or other substances; the agglutination tests for typhoid, dysen-
tery, cholera, typhus, and many other diseases; the Wasserman, Kahn,
and other tests for syphilis; the typing tests for the pneumococci of
lobar pneumonia; and many others that are less well known but no
less useful when needed.
As therapeutic aids I may mention antitoxins for diphtheria, tetanus,
scarlet fever, and a number of other diseases, which have made deaths
from some of these diseases under ordinary conditions nothing short
of criminal negligence; the helpful injections of typed pneumococcus
serum in pneumonia; the use of immune or convalescent. serum in
cerebrospinal meningitis, anthrax, measles, and most recently influ-
enza; and the life-saving properties of antivenin for snake bites.
As preventive aids I need only call your attention to the wonderful
records achieved by the use of vaccines against typhoid, paratyphoid,
diphtheria, and more recently yellow fever. This once dreaded dis-
ease is now looked upon by the United States Public Health Service
as of less consequence than the relatively mild and tolerated dengue
fever, merely because our Government has a bank of a million protec-
tive doses of vaccine which it can release if ever a case occurs within
our borders. In recent years success has also been attained in produc-
tion of vaccines against typhus fever and spotted fever, the former of
324 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
which has hitherto been the scourge of every great war. In the present
war man-made implements of destruction are more deadly than ever
before, but there is no question but that this added deadliness is more
than compensated for by protection from diseases, which, up to the time
of the Spanish-American war, always wrought more havoc than the
enemy. Such diseases as typhoid, dysentery, typhus, tetanus, and yel-
low fever have been shorn of their power by protective vaccinations.
Closely related to the field of immunology is blood typing, which
has placed blood transfusion on a safe and sound footing, and made
it as routine a procedure as anesthesia or surgical asepsis. In spite
of the accomplishments in the field of immunology in recent years, I
think we may confidently look forward to ever greater things in the
years to come. Within the past 12 months success has been attained
for the first time in the artificial production of antibodies in laboratory
flasks. This may open the door to future developments which may
surpass anything we have yet been able to hope for.
I wish now to turn your attention to another field of biology that
has contributed enormously to medicine—the science of endocrinology.
No sorcerer or magician of old ever dreamed of accomplishing the
miracles that can be performed today by the application of knowledge
in this field. Osler, speaking of the effect of thyroid extracts on those
horribly misshapen, doltish creatures known as cretins, says, “Not the
magic wand of Prospero or the brave kiss of the daughter of Hip-
pocrates ever effected such a change as that which we are now enabled
to make in these unfortunate victims, doomed heretofore to live in
helpless imbecility—an unmistakable affliction to their parents and
their relatives.”
The science of endocrinology was born of primitive beliefs in organ
magic. When our remote ancestors began to indulge in the art of
thinking and had reached the stage at which they could weave together
a number of scattered observations and come out with a general idea,
it was a natural deduction that the kind of food you ate was a big
factor in determining what sort of person you were. Tigers were
thought to be fierce because they ate raw meat; it was overlooked
that a tiger fed on lettuce and carrots would undoubtedly be fiercer
still, and that a meat eater had to be fierce to get his meat whereas a
vegetarian could afford to be timid and fleetfooted. Such thoughts,
traveling along a single track, eventually reached the conclusion
that courage could be acquired from eating the hearts of courageous
animals or men, intelligence from eating brains, and so on. The
psychological effects undoubtedly provided ample circumstantial evi-
dence for the truth of the assumptions.
Modern endocrinology began in 1889 when a famous French scien-
tist, Brown-Sequard, claimed remarkable rejuvenating effects in him-
BIOLOGY AND MEDICINE—CHANDLER 325
self from injection of gland extracts. His results, too, were prob-
ably psychological, but his prestige was such that his claims started
a development in medicine that has had more profound significance
than any since Pasteur’s discoveries of the bacterial origin of disease.
The human body is a highly automatic, self-regulating mechanism.
Nature’s primitive means of regulation of the body of an organism is
by chemical substances secreted by its tissues. Superimposed on this,
later in evolution, is an involuntary nervous system, useful in making
rapid and temporary adjustments that become necessary for a body
with ever-increasing activities and more and more complicated rela-
tions to its environment. Still later in evolution Nature added a
voluntary nervous system but very wisely refrained from giving it
control over the internal regulation of the body. As Dr. Cannon
remarks, we should be greatly bothered if in addition to attending
to the business of other people we had to attend to our own. The
internal affairs of the body are too important to be subject to a well-
meaning but neglectful and incompetent intelligence, which would
as likely as not be concerning itself with the flight of a golf ball when
it ought to be attending to the rate of the heart beat.
The chemical method is still the fundamental means of regulation of
the body. Chemicals produced by tissues, which we call hormones, con-
trol such functions as growth, development, metabolism, and reproduc-
tion, and adapt the body gradually to climatic fluctuations, variations
in activity, nutritional changes, pregnancy, lactation, etc. The human
body is one of the most thoroughly integrated and communistic or-
ganizations imaginable, every part sharing, according to need, with
every other part, and each part influencing every other part. It is a
prevalent view today that every tissue and organ in the body produces
hormones or hormonelike substances that help in the integration of the
entire organism. As bodies became more complex during the course
of evolution, however, and the regulation more difficult, a number
of special glands for production of particularly potent hormones were
developed. These are what constitute the endocrine system. Some of
the glands are completely separate organs having no other functions,
such as the thyroid, pituitary, and adrenals. Others have developed as
special tissues in already existing organs, as in the pancreas, liver,
and sex glands.
The potency of these glands is almost incredible. They very largely
determine what we are and how we behave. They dominate our physi-
cal stature, our mental development, our emotional status, our repro-
ductive activity, the rate at which we live, and our ability to make
use of our food. They are the architects of our bodies and the mould-
ers of our character. A puppy deprived of its anterior pituitary gland
may be converted from an aggressive, pugnacious creature to a whimp-
326 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
ering coward, and may be returned to its former state by pituitary
injections. Injections of prolactin into rats with no trace of maternal
instincts will fill them so full of mother-love that they will even mother
baby squabs instead of eating them. One is led to interesting specula-
tion as to whether injections of prolactin might not be a good alterna-
tive to execution for despotic dictators.
The hormones produced by the endocrine glands, some stimulating
and some inhibitory, not only affect the body as a whole in many
complex ways, but they interact with each other in such an intricate
manner that we are still very far from ideal utilization of them, and
we may look forward to a great extension in the future. Yet even
now, only 50 years from the birth of the science, the use of hormones
has revolutionized a large part of medical practice and has given new
insight into many physiological processes, such as metabolic rate,
sugar metabolism, blood pressure, menstrual disorders, psychotic mal-
adjustments, adiposity, sexual aberrations, and reproductive difficulties.
Now let us turn to another contribution of biology to medicine—
knowledge of nutrition. For lack of time I will pass briefly over
many interesting discoveries connected with metabolism of proteins,
fats and sugars, utilization of minerals, etc., though in passing I
must pause long enough to mention a relatively new tool in physiologi-
cal research—the use of ions tagged by means of atoms of unusual
weight or made radioactive in cyclotrons. By this means it has been
found that molecules in the body, even those supposed to be relatively
stable in bones, teeth, or fat, are forever being shifted about and re-
placed by new ones. The body is even less stable than it was thought
to be.
The most significant discoveries in. nutrition, ranking close to the
discovery of hormones in their importance to human welfare, were
those of the vitamins. Since the days of leopard-skin dinner jackets
and struggles with cave bears instead of dictators, man’s ways of
life have undergone many changes and so have his foods. With the
development.of agriculture and civilization his food became less varied
and more highly manipulated. He began to live more extensively
on grain, to store food for periods of famine, and to cook it. Later
he began throwing away the vitamin-bearing parts of his cereals,
developed a taste for refined sugar, protected himself from sunlight,
and often lived for months without fresh fruits or vegetables. Beri-
beri, scurvy, rickets, pellagra, and night blindness attacked whole
populations.
Except for the cure of scurvy by eating lemon juice or hemlock
leaves some 200 years ago, nothing definite was known about these
nutritional-deficiency diseases until Eijkmann began experimenting
with diseased fowls in Java 45 years ago. Gradually during the last’
30 years a whole alphabet of vitamins has been discovered, but it is
BIOLOGY AND MEDICINE—CHANDLER 327
only within the last decade that they have been obtained in chemically
pure form, and synthesized. Few people even today realize the im-
portance of this. Although this country is probably the best fed in
the world, I do not believe it is an exaggeration to say that 50 and pos-
sibly 75 percent of the American people do not have optimum amounts
of all the vitamins they should have. They do not have scurvy or
beriberi or rickets, but they have a host of minor illnesses or troubles
that they need not have. Some British authorities have gone so far
as to say that 99 percent of so-called common illnesses are directly or
indirectly due to vitamin deficiencies. Allowing 100 percent expansion
for enthusiasm, the figue is still impressive.
The common effects of vitamin deficiencies are such things as night
blindness, susceptibility to colds, unhealthy teeth, poor appetite,
gloominess, nervousness, and a tendency to fly into tantrums. An
abundance of vitamins leads not only to a state of superhealth in people
who have always considered themselves reasonably healthy, but it is of
great help in recovery from acute or chronic diseases, repair of wounds,
and resistance to infection. Even yet, many medical men tend to look
upon synthetic vitamins as medicine rather than supplementary food,
but gradually this is changing, and it is encouraging to see more and
more foods fortified by added synthetic vitamins. Because of. this
and the more even distribution of vitamin-bearing foods by rationing,
the general level of nutrition in England, in spite of several years of
war, is better than it has ever been before. It is becoming more and
more so in this country too.
The definition of medicine includes the prevention of disease as
well as its cure and alleviation. Some attempts at preventive medi-
cine were made when disease was supposed to be caused by demons,
for it was a natural inference that if the demons could be ejected they
might also be prevented from entering. With the development of
the humoral theories, preventive medicine was almost completely
forgotten, since no one had even guessed as to how the humors could
be kept in order before they got out of balance. Prevention of dis-
ease is a phase of ecology, and involves knowledge of normal bodies
and their relation to their environment, including climate, atmosphere,
and geological formations, as well as relations to such fellow creatures
as rats, mosquitoes, lice, hookworms, amoebae, and bacteria, to say
nothing of viruses. .
It is only in very recent times that anything whatever has been
known about this phase of medicine. Only in a few instances have
the processes of trial and error that led to curative and alleviative
procedures led to practices that prevent disease. One of the first
great triumphs in curative medicine was the discovery, in 1640, of
the value of extracts of cinchona bark as a cure for malaria, but it was
619830—45——=22
328 |= ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
not until the end of the nineteenth century that a basis for the pre-
vention of malaria was discovered.
A few practices of primitive people suggest attempts, probably
unwitting, to prevent disease. In India, for instance, I found a
primitive tribe, the Santals, who never drink water directly from a
stream or pond, but from a little hole in the sand a foot or.so away,
thus practicing sand filtration, one of the prime tools of modern san-
itary engineering. The unfitness of natural water for drinking was
recognized long ago. Cyrus of Persia carried boiled water for his
troops 2,500 years ago. The low repute of water as a beverage even
in the unenlightened middle ages is evidenced by a thirteenth-century
writer who, describing the extreme poverty of Franciscan monks who
settled in London in 1224, exclaimed, “I have seen the brothers drink
ale so sour that some would have preferred to drink water.” The
head-hunting, carrion-eating Nagas of the Assam hills drink only a
rice beer, carrying starters with them when they go on trips.
Preventive medicine as practiced at present has three principal legs
to rest on: (1) the upkeep of natural resistance by general hygienic
measures, including a proper hormone balance and optimum nutrition ;
(2) the artificial stimulation of specific immunity or resistance; and
(3) protection against access of disease germs via water, food, air,
or insect transmission.
The general principles involved in the first of these have been known
for a long time, but the details have only recently been filled in by
the discoveries with respect to hormones, minerals, and vitamins that
I have already mentioned. I have already called your attention to
the fact that in an epidemic only a small percentage of the individuals
that are actually exposed develop a disease. The determining factors
are the dosage of germs that gain access to an individual, and the
natural resistance he has. The higher the natural resistance, the
greater the dosage he can withstand.
The second leg on which preventive medicine rests, artificial stimu-
lation of immunity, I have already discussed. On it we depend very
largely for our protection against smallpox, diphtheria, tetanus, rabies,
yellow fever, spotted fever, typhoid fever, and many other diseases.
The third leg on which preventive medicine rests — protection
against dissemination of germs—I have so far said little about, but
here enormous strides have been made within a short space of time.
Famous in sanitary history is the case of the Broad Street pump in
London in 1854, around which centered an explosive outbreak of
cholera. After everything from the chemical nature of the soil to
dust bins in cellars had been investigated, the relationship between
drinking water from the well and attacks of cholera became clear.
Nature had provided a grim lesson out of which grew modern sani-
tary engineering. In the intervening 90 years modern water purifi-
BIOLOGY AND MEDICINE—CHANDLER 329
cation and sanitary sewage disposal have developed. Whereas in
1900 the American death rate from typhoid was 36 per 100,000, today
it is about 1 per 100,000, and in 1942 more than half of our large cities
had not a single typhoid death.
Milk and food sanitation are even more recent developments. Eyen
95 years ago a child ran the risk of acquiring disease every time he
drank a glass of milk; today the greater part of the milk supply in
almost every city is pasteurized, and many cities can boast of having
no raw milk, .
Just 50 years ago two American workers, Smith and Kilbourne,
laid the foundation stone for medical entomology when they demon-
strated the transmission of a disease—Texas fever of cattle—by means
of atick. Five years after that the mosquito transmission of malaria
was proved and then, at the turn of the century, came the brilliant work
of an American Army commission in Havana, proving the transmission
of yellow fever by mosquitoes.
Today medical entomology plays a large part in our lives. By con-
trol of insects, ticks, or mites we are able to control, in some cases
almost to exterminate, many important diseases, including some of
the most.important. I need only mention the prevention of malaria,
yellow fever, and dengue by mosquito control, of epidemic typhus and
relapsing fever by delousing methods, of plague and endemic typhus
by control of rats and fleas, and of dysentery by fly eradication.
Already we have become so accustomed to the benefits from all
these protective devices that we take them for granted. Only when
circumstances interfere with their practice, as is often the case in war,
do we realize how much we depend on them. It was dysentery, not
the Turks, that defeated the British at Gallipoli, and it was dysentery
and malaria, not the Japs, that defeated our own troops at Bataan.
As we go on into the future, preventive medicine will play a larger
and larger part in our lives. Instead of being a secondary and rela-
tively unimportant part in the curriculum of our medical schools, I
predict that we shall have many schools devoted primarily if not
exclusively to this fast-growing branch of medical science, which is
still so young that it is seldom allowed to stand on its own feet. The
‘subjects taught will be very largely biological ones, such as medical
entomology, helminthology, protozoology, bacteriology, immunology,
the newly developed field of aerobiology, and methods of sterilization
and disinfection which are also a branch of biology, since they deal
with the destruction of life.
In addition to the categories of discoveries in biology that I have
already mentioned, there are other fields of biological research which
are making valuable contributions to both preventive and therapeutic
medicine. I have time only to mention in passing a few of the
discoveries made in the year 1942.
330 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
During the past year great advances have been made in the long-
neglected field of aerobiology, dealing with the distribution of pollens,
fungus spores, micro-organisms, etc., through the air; new knowledge
of the spread of contagion through the air has been obtained, and
new methods of control worked out, using vapors and ultraviolet rays.
Also within the year there have been a number of new biological
methods of controlling pathogenic organisms, including discovery
of an enzyme-like substance in young rats, by which tuberculosis ba-
cilli may be shorn of the waxy coats that protect them from drugs
and phagocytes, and discovery of germ-killing substances extracted
from molds and from various types of soil bacteria. In the field of
nutrition, evidence for the need of particular amino acids for special
functions in the body have been demonstrated, and may pave the
way for better control of these functions in the future. New methods
have been developed for the study of the ultimate connections be-
tween nerves and muscles, which may lead to better control of paralysis
and muscular diseases. Announcement has also been made of the de-
velopment of germ syrups, at negligible cost, which change the bac-
terial life of the human intestine so that, like deer and cattle, we can
not only digest the cellulose of grass, leaves, and wood, but can also
synthesize our own supply of B vitamins within our own bodies. In
research on cancer, which is one biological problem that is still un-
solved, a number of significant advances have been made. A few
more pieces have been fitted into the mosaic, bringing the final pic-
ture a little nearer to completion. In this field as in that of allergies,
there is still much to be done, but there is every reason to believe that
it will be done before very long.
Man’s ingenuity has freed him from many phases of the struggle
for existence to which other creatures are subject. He has gained
an insuperable advantage over the wild beasts, and his inventive genius
defies the attacks of climate and the elements. In his struggle against
disease he has, as we have seen, made wonderful progress, although
he still has far to go. There is some reason to hope that after the
present global war has burned itself out we may be able to free our-
selves from the one phase of the struggle for existence that man’s
ingenuity has steadily made more terrible, the struggle of man against
man. With all the phases of the struggle for existence well in hand
we may then turn to a struggle for improvement of our kind by the
application of two other branches of biological science, genetics and
eugenics. Within our own generation preventive medicine has
grown out of therapeutic medicine; perhaps our children may live
to see a still newer branch of “improvement medicine,” in which en-
docrinology, nutritional studies, problems of aging and rejuvenescence,
and eugenics will lead to greater health, more happiness, longer life,
and better evolutionary prospects than have hitherto been our lot.
THE LOCUST PLAGUE?
By B. P. Uvarov, D. Se.
Entomologist, Anti-Locust Research Centre, British Museum (Natural History)
THE OLDEST ENTOMOLOGICAL PROBLEM
The locust problem has confronted man since the earliest beginnings
of agriculture. Biblical references to locust plagues are well known,
and Joel’s description of a locust invasion has never been surpassed for
its dramatic picturesqueness combined with amazing accuracy of detail.
The earliest known record of locusts is a picture of a locust on the wall
of an Egyptian tomb of the Twelfth Dynasty, about 2400 B. C. Ref-
erences to locusts abound in ancient Egyptian, Hebrew, Greek, and
Chinese texts, and Roman writers such as Titus, Livy, and Pliny have
left us many data, some fantastic, but some of definite value. <A criti-
cal examination of this information is still awaited, and it may shed
new light on certain sides of the problem.
The more recent literature on the locust problem is enormous, and
the number of books and papers on the subject was estimated 15 years
ago at about 2,000; since then this figure has been almost doubled,
owing to intensive new research. The more important contributions
are published in about a dozen languages, and the task of coping with
this flood is not an easy one.
WORLD-WIDE PROBLEM
It is often thought that locust plagues are restricted to a few coun-
tries and that the world at large need not be concerned about them.
This view is largely due to the fact that central and northwestern
Europe is now practically safe from locusts, though its southern coun-
tries, e. g., Portugal, Spain, Italy, the Balkan Peninsula, the Ukraine
and the Caucasus, know their depredations only too well.
The zone where agriculture has to reckon with locusts and their
lesser relatives, grasshoppers, becomes even wider in temperate Asia,

by permission of the Royal Society of Arts. The object of the present paper is to give a brief
account of the locust problem and to show how recent advances in its study have made it
possible to envisage its lasting solution.

332 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
where a broad belt of the fertile Siberian lands produces not only
grain in abundance, but also grasshoppers which take their toll of
the harvest. South of that belt, Soviet Middle Asia, producing cotton,
fruit, etc., is subject to ravages of the Asiatic migratory (Locusta
migratoria migratoria) and the Moroccan (Dociostaurus maroccanus )
locusts. Farther east, in China, the Oriental migratory locust (Locusta
migratoria manilensis) has repeatedly caused wholesale famines, and’
is actually causing untold miseries at present. The range of this
locust extends to the Philippine Islands, where records of its ravages
are found in the earliest Spanish chronicles, and to Borneo, Celebes,
Indo-China and the Malayan peninsula.
Returning westward again, we meet the vast zone where the desert
locust (Schistocerca gregaria) holds its sway over agriculture, which
is here carried out always under precarious conditions, making its
products particularly precious to the population, so that a loss of
harvest amounts to a major catastrophe. It is this desert locust that —
has been known to man since Biblical times, and which is still as
active as it was thousands of years ago. The area of its depredations
is enormous, stretching from India in the east to the Atlantic coast
of Africa in the west, and from Russian Middle Asia in the north to
below the Equator in eastern Africa. The tropical parts of Africa also
have to cope with two other kinds of locust, the African migratory
(Locusta migratoria migratorioides) and the red (Nomadacris sep-
temfasciata) locust. The latter extends its ravages to South Africa,
which, in addition, has a very serious problem in the endemic brown
locust (Locustana pardalina).
Australia, the continent where agricultural development started rela-
tively recently, but where it has made great strides, is already paying
a heavy tax to locusts and grasshoppers.
Turning to the Western Hemisphere, both the United States and
Canada have to wage an almost incessant war against grasshoppers,
while wide regions in Central and South America are periodically dev-
astated by swarms of the American locust (Schistocerca paranensis).
Thus, none of the five continents is free from these pests, which, in
fact are absent only from the forest and the tundra belts in the north,
from the equatorial forests, and from the high mountains. The regions
either permanently infested by them or subject to their periodical in-
cursions include no less than 77 separate countries (fig. 1).
WHAT LOCUSTS COST THE WORLD
Beginning with the Egyptian locust plague, described in the Bible,
there runs through history a tragic tale of devastations caused by
locusts, followed by famines decimating populations of whole countries.
Thus, in the Roman colonies of Cyrenaica and Numidia no less than

334 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
800,000 people died in the year 125 B. C. after a locust invasion. Great
famines have been caused by locusts in India, China, and other coun-
tries. As recently as 1930, losses of crops estimated at nearly 1,000,000
pounds were caused by locusts in Morocco. In Nigeria, in the same
year, 1,000 tons of grain had to be imported to prevent famine; in
Tanganyika Territory 75 to 100 percent of native crops were destroyed
in 1929, and in Kenya in the same year £200,000 had to be spent on
relief from the famine caused by locusts and drought.
These are impressive figures, but it may be argued that locust inva-
sions occur only periodically, and that a distorted picture of their eco-
nomic importance is obtained by considering exceptional cases.
To assess the cost of locusts and grasshoppers to the world, the Anti-
. Locust Research Centre attempted to collect statistical data for a
10-year period, 1925-34, which covered both bad locust years and those
free of them. Statistics of this kind were not easy to obtain, and only
49 countries (out of 77 suffering from locusts) submitted them. Never-
theless, the total was staggering, showing that crops to the value of
£83,120,800 went to feed the locusts in 10 years. The losses would cer-
tainly have been greater if no defensive measures had been taken, but
the latter cost another 13 million pounds. On the basis of these figures,
it was not an exaggeration to estimate the average cost of locusts and
grasshoppers to the world at 15 million pounds per annum. To this
must be added the enormous figure of unpaid labor which is used almost
everywhere for large-scale defensive measures. The data on this point
are very incomplete, but the number of man-days often runs into
millions in one year and in one country.
AGRICULTURAL PROGRESS AND LOCUSTS
It has been argued that locusts and grasshoppers represent a danger
only in backward countries, and that the advance of agriculture should
inevitably lead to their disappearance as pests. A long interval during
which the United States of America were almost free from grass-
hoppers led some of the most eminent American entomologists to
believe that agricultural progress had made a repetition of the grass-
hopper plagues impossible. These hopes were rudely shattered in re-
cent years, when grasshopper outbreaks recommenced on a truly Ameri-
can scale.
Moreover, there are definite cases on record where direct encourage-
ment was given to locusts by otherwise excellent developments. The
Danube delta, for example, had become unsuitable for locust breeding
on a large scale toward the end of the last century, but recent regulation
of the river channel resulted in the emergence of new areas of land
which were quickly utilized by locusts, and an area which had not
produced locust swarms for many years became again a source of
LOCUST PLAGUE—UVAROV 335
danger. In northern Borneo, locusts can breed only in areas where
the jungle has been cleared for cultivation and abandoned after a few
seasons; such shifting cultivation there, and probably in other similar
areas, is a direct cause of locust outbreaks. In western Australia,
the clearing of dry forests in the interests of sheep breeding has created
a type of grassland admirably suited for locusts. Overgrazing of
natural pastures is largely the cause of the great, and growing, grass-
hopper menace in Argentina, some parts of the United States, Canada,
and parts of Russia. Such facts led the Fourth International Locust
Conference, held in 1936 at Cairo, to pass a resolution pointing out that
the mass development of locusts and grasshoppers is furthered rather
than hindered by man’s activities, and that no hopes can be entertained
of the problem’s becoming less acute merely as a result of the general
development of a country.
To this must be added the consideration that the agricultural de-
velopment of new areas, e. g., in Africa, central Asia, etc., tends to
increase the danger from locusts in direct proportion to the increase
in the value of crops exposed to their ravages.
THE USES OF LOCUSTS
It may well be asked whether it might not be possible to find some use
for the mass of organic matter represented in locust swarms, some of
which have been estimated to amount to hundreds of tons. Chemical
analyses show that locusts contain protein, fats, and mineral salts,
which would be of value in the preparation of fertilizers and of food
for cattle and poultry. From the technical point of view the idea is
sound, but no industry can be based on a raw material which may be
overabundant one year and nonexistent the next.
The use of locusts for food is well known, since John the Baptist
lived on them, as Bedouins in Arabia still continue to do when other
food is scarce. The Assyrians apparently considered locusts as food fit
for kings, since a bas relief of the seventh century B. C. shows locusts
being brought up to the table of Asshurbanipal. Locusts are still
eaten in many countries, and the Philippine Department of Agricul-
ture has recently published a pamphlet describing 33 different ways
of cooking them. Some of the recipes sound rather attractive in war-
time, perhaps, because they include such ingredients as eggs, bananas,
lemons, and pineapples. More plainly cooked locusts were recently
described by an entomologist as “neither repulsive nor producing any
pleasant sensation.”
LOCUSTS AND THEIR HABITS
We have been speaking of locusts as a plague of agriculture, but in
order to understand the problem, it is necessary to have a clear idea
336 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
of what locusts are and how they live. A locust is nothing but a spe-
cies of grasshopper, but usually larger in size and characterized mainly
by gregarious habits.
The life cycle of locusts and grasshoppers is fairly simple. The
eggs are deposited by the female in the soil, in packets, or “egg-pods,”
each containing 30 to 100 eggs. In countries with a cold winter, eggs
lie dormant throughout this season, and in spring the young locusts,
or “hoppers,” emerge from them onto the surface of the soil. In the
Tropics, the eggs may hatch in 2 to 3 weeks, if there is rain or moisture
in the soil. The difference between grasshoppers and locusts becomes
apparent in the hopper stage; the former may be numerous, but each
one lives independently of the others, whereas the latter congregate
in dense groups, or bands. Further development consists in rapid
growth, stimulated by voracious feeding on green vegetation, and in
the periodic moulting which occurs 4 to 6 times before the adult insect
appears; these differ from the hoppers only in size and the presence
of two pairs of wings. The whole cycle occupies a year in temperate
climates, but in the Tropics there may be several generations within a
year.
The most striking feature in the behavior of locust hoppers is their
mass movement in bands, which may cover several square miles. The
relentless march of hopper bands which are not stopped by obstacles,
even by water, creates an impression of a dark purpose, of a movement
toward an objective, and many more or less fantastic explanations
have been offered to account for it. Recent investigations have, how-
ever, definitely proved that the movement of hoppers depends very
largely on temperature and occurs only on sufficiently hot days, while
excessive heat again causes it to stop. The hopper movements are not
caused by hunger and do not aim at finding food, since hoppers, driven
by heat, often leave a fertile area and march into open desert.
When hoppers become adult and acquire wings, they soon begin to
fly about in swarms. Again, a swarm does not leave an area because
of lack of food, and it does not necessarily fly toward more fertile
lands, but its flight is initiated, directed, and interrupted by various
weather factors. Swarms may reach great size and contain fantastic
numbers of individuals. Thus, a swarm in East Africa measuring
3 by 60 miles was estimated to consist of a million million locusts; and
even larger swarms are on record.
The distances covered by swarm flights may be enormous. In 1693,
swarms of the migratory locust from the Danube delta reached Wales,
at a distance of about 1,600 miles in a straight line, though probably
not in a single flight. A swarm of the desert locust was encountered
in the Atlantic midway between South America and Africa, about
1,500 miles from the latter, whence it certainly came. This must have
LOCUST PLAGUE—UVAROV 337
been a single sustained flight. As will be seen later, the extent of
migrations becomes even greater when the swarms of several succes-
sive generations are considered.
METHODS OF LOCUST CONTROL
It would be impossible even to enumerate here the many methods
used, or recommended, for locust destruction. It is of interest, how-
ever, to point out that some of them are centuries old and are still
in use. The destruction of eggs by digging was practiced in ancient
China and is still widely recommended, though it is effective only in
some special cases. Beating of hoppers by branches and driving
them into trenches were the methods enforced by the Romans in
North Africa, according to Pliny, and are still practiced in spite of
being of little value and involving the use of forced labor in astro-
nomical quantities.
In more recent times, endless new methods have been proposed and
tried against locusts, such as the use of flame throwers, poison gases,
bacterial diseases, steam rollers, balloon barrages, smoke screens, and
even artillery. Lately, the method of poison baits has come into
almost universal use. Bran, moistened with sodium arsenite solution,
is scattered thinly on the ground and proves to be more attractive to
locusts than green food. When the low dosage of poison, sufficient to
kill locusts but not grazing animals, is strictly adhered to, there is
no danger from baits, but it would obviously be an advantage to
eliminate all risks. This may eventually be achieved by investiga-
tions, now in progress, with dusts which would kill locusts by contact
and which could be sprayed from aircraft.
However, even some of the relatively primitive methods may be
of use for destroying locusts. Indeed, it is definitely not the lack of
the proper technique which hampers the solution of the problem.
ANTI-LOCUST POLICY OF THE PAST
The main stumbling block in the way of a solution of the locust
problem is the fact that locust depredations do not recur annually
but in cycles of several years, separated by clear intervals. When a
country is invaded, no effort is spared to organize defense, which is
rarely effective, since the organization usually lags behind the inva-
sion. As soon as the immediate danger is over, the anxiety gives
way to wholly unjustified hopes that perhaps the invasion will not
recur, or at least not in our time, and nothing is done until the next
catastrophe, which again occurs unexpectedly. It is this unfounded
optimism that should be considered as the first cause of the continual
recurrence of locust plagues over the centuries.
338 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
The second reason for the failure to control locusts is the isolation-
ist policy of practically every country subject to their depredations.
History provides examples of great efforts to control locusts in
Algeria, South Africa, Argentina, etc., but the results were always
temporary and never led to a radical solution of the locust problem,
simply because it is insoluble within a single country. - We have seen
that swarms in their flights may, and do, cover great distances, and
that they completely lack respect for any man-made boundaries.
Swarms of the desert locusts, bred in India, usually migrate to Per-
sia and Arabia, and their progeny proceed to Egypt, Palestine, and to
East Africa. It is clear that control measures in any one of these
countries, however effective, may only protect the standing crops of
the particular season, but will have no effect on the general situation.
Sporadic attempts to approach some measure of international
cooperation have not been lacking. Conventions pledging each coun-
try to control locusts within its own confines have been concluded
between groups of adjoining countries (e. g., South American Repub-
lics; Iraq, Syria, and Turkey; Persia and the Soviet Union, etc.),
but most of them remained paper agreements only and had no prac-
tical effect, because they all aimed at defense only, and no attempt
was ever made to take concerted measures toward a lasting solution
of the problem.
The most spectacular failure of such attempts to solve the locust
problem by resolutions was the Rome International Conference of
1920. A convention pledging their countries to take all the necessary
measures against locusts was signed by delegates of 18 countries,
widely scattered over the globe. It appeared incomprehensible why
Madagascar should join forces with Mexico, or Bulgaria with Uru-
guay, since they are threatened by entirely different species of locusts,
and the course of events in one of them could not possibly have any
effect on the other; and the solution of the locust problem remained
unattainable as long as it was approached without sufficient scientific
basis, though it was certainly right to regard the problem as an inter-
national one.
SCIENTIFIC BASIS OF A NEW POLICY
The irregular periodicity of locust invasions hampered scientific
research on the problem, just as it did the organization of locust con-
trol. It was naturally difficult to persuade governments to spend
money on locust research in the periods when swarms were absent,
and little could be accomplished during the locust years, when all
efforts were concentrated on defense. Asa result, there was no answer
to the question : “What happens to locusts when there are no swarms?”
Since locusts matter only when they are in swarms, it appeared idle
LOCUST PLAGUE—UVAROV 339
curiosity to ask the question, but, fortunately, scientists are often at-
tracted by “useless” problems. In this case, entomologists in Russia
and in South Africa undertook investigations, and almost simultane-
ously, and quite independently, arrived at wholly unexpected, but
closely similar conclusions. It was found that locusts in the years
when they are not numerous differ from the swarm locusts in appear-
ance and in habits. The external differences between the swarming
and the solitary phases of locusts, as they came to be known, are some-
times so pronounced that the two phases were considered by specialists
as belonging to different species. As regards habits, locusts of the
solitary phase are typical grasshoppers, showing no inclination to
form dense bands and swarms. Should, however, the numbers of
locusts in a restricted area increase, so that crowding results, the
locusts acquire strong gregarious tendencies. The phenomenon of
phase variation in locusts has since been subjected to intensive studies,
and many interesting details have been discovered, but the point of
outstanding practical importance was that it opened up a possible
approach to the problem of the origin of locust outbreaks.
NEW PERIOD OF INVESTIGATIONS
In 1928, a serious outbreak of the desert locust started to develop, and
the British Government decided that steps should be taken to con-
sider not only defensive measures, but also the possibility of a radical
solution of the problem by ascertaining the reasons for the periodical
swarming of locusts, with a view to their control. A Locust Sub-
Committee of the Committee of Civil Research (later transformed
into the Committee on Locust Control of the Economic Advisory
Council) was formed on April 29, 1929, and that date may be taken
as the threshold of a new anti-locust policy. The actual work was
entrusted to a special research unit, under the supervision of Sir Guy
A. K. Marshall, then Director of the Imperial Institute of Entomol-
ogy, and under the technical direction of the present writer. A
scheme for collecting current information on locust movements and
breeding in all countries of Africa and the Middle East was intro-
duced, and several field investigators were sent out to study the prob-
lem on the spot. The organization, set up as a purely British one,
rapidly attracted attention in other countries, and the First Inter-
national Locust Conference at Rome in 1930 requested the British
organization to act as the International Centre for Anti-Locust Re-
‘search, where all the information on the subject could be centralized.
The years 1930-38 witnessed a unique concentration of scientific effort
on locust investigations. Parties of British, French, Belgian, South
African, Indian, and Egyptian experts systematically explored one
area after another; spending months in the regions which are rightly
340 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
regarded as most inhospitable; establishing temporary field labora-
tories; and gradually disentangling the many threads of the great
problem. Nor was this extensive work uncoordinated, since practi-
cally every year the experts and other representatives of the countries
involved came together for a conference, to pool the results and to plan
further campaigns. The accumulation of information on locusts at
the International Centre, in the meantime, went on, with a steady im-
provement in the unified reporting system, which by now covered the .
entire continent of Africa and a substantial portion of Asia. All
countries in that immense region submitted monthly reports on the
locust situation. These reports were critically examined, summarized
and mapped, so that all developments in the situation could be fol-
lowed step by step.
A feature of this international effort was its development without
the signing of formal conventions and on a basis of direct collabora-
tion between experts of many nations, with the ready support of their
governments.
The results of this teamwork, which is certainly unique in entomo-
logical history, have justified the effort. At the outset of the investi-
gations, practically nothing was known on the distribution of the
different species of locusts in Africa, on their seasonal cycle and migra-
tions, and particularly, on the origin and the course of their periodical
outbreaks. After 8 years of intensive work, a clear picture of the
whole problem became available, which has made it possible to formu-
late an entirely new anti-locust policy, aiming at a radical solution
of the locust problem.
NEW ANTI-LOCUST POLICY
The investigations just outlined have provided abundant evidence
that the periodicity of locust outbreaks is closely connected with the
periodical transformation of the harmless solitary phase into the
dangerous gregarious one. Such a confirmation of a scientific theory
may appear of no importance except to experts, but actually the theory
has supplied the key to the whole problem. It was proved that the
transformation into the gregarious phase can happen, in the case of
each locust species, only in certain relatively restricted areas with
peculiar natural conditions, and it is only in these outbreak areas
that the first swarms can be formed. In the case of the African migra-
tory locust it was shown that a few small swarms arising about 1928
in a restricted area on the middle Niger in the French Sudan were
the cause of an invasion which in 5 years swept over the greater part
of the African continent (fig. 2). The outbreak areas of the red
locust have been located in Tanganyika Territory and in Northern
Rhodesia. With regard to the desert locust, it was found that its
LOCUST PLAGUE—UVAROV 341
swarms can arise from the scattered locusts of the solitary phase on
the coasts of the Red Sea, in Baluchistan, and in Mauretania.
The fact that the great locust invasions are due to very small be-
ginnings has important implications, for once the original outbreak

areas are known, they can be put under permanent observation and
any tendency on,the part of the solitary locusts to form incipient
342 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
swarms can be suppressed before they have had a chance to spread
elsewhere. The new policy of locust control aims, therefore, at pre-
venting the outbreaks instead of allowing them to develop into in-
vasions and then trying to devise desperate defense measures.
This policy of prevention of locust outbreaks is clearly more
rational than the old defensive policy. It is also more economical,
requiring a regular annual expenditure of only a small fraction of
the average annual cost of the defensive measures, apart from eliminat-
ing the losses due to invasions.
By the year 1938, the international investigations had advanced
so well that it was possible to formulate practical plans for dealing
with the three main locust species affecting Africa and the Middle
East. At the Fifth International Locust Conference held at Brussels
in 1938, definite schemes were elaborated for establishing permanent
organizations for the control of the desert, migratory, and red locusts.
These plans, naturally, required further discussions of administrative
and financial details, and these extended into 1939, when the out-
break of the war made the locust problem appear insignificant.
Very soon, however, it became apparent that the war would demand
a maximum production of foodstuffs and that crops must be safe-
guarded from locusts. Unfortunately, most of the outbreak areas of
the desert locust were near, or very close to, the war zone, and the out-
break areas of the migratory. locust became inaccessible to outside
experts after the fall of France. There remained only the red locust,
and the scheme for its control, supported by the British colonies and
protectorates in East Africa, by Southern Rhodesia and the Belgian
Congo, was launched in 1940. Recently, it became known that an
organization for preventive control of the migratory locust has been
established by French authorities without waiting for international
support, which must be given as soon as possible. Thus, in spite of
the war, the foundation stone of permanent international locust con-
trol was laid.
LOCUSTS AND THE WAR
It was a most unfortunate coincidence that, after a quiet interval
of several years, the desert locust exhibited signs of renewed swarm-
ing just as the war broke out and the first swarms had a chance to
escape observation and destruction. By the time the areas in ques-
tion had become more accessible, the swarms were not numerous, but
sufficiently widespread to necessitate an urgent campaign for the
protection of crops throughout the Middle East and East Africa.
From the point of view of organization, war conditions proved to
be, paradoxically, more favorable for an anti-locust campaign than
normal times. The importance of safeguarding vital food supplies,
both for the troops and the population, became a powerful factor in
LOCUST PLAGUE—UVAROV 343
obtaining the willing cooperation of all concerned. This made it
possible, for the first time in the history of locust control, to organize
not a dozen small national campaigns designed mainly for defense,
but a unified campaign embracing the whole affected area and assum-
ing the character of offensive operations. These operations are based
on a knowledge of the seasonal movements of swarms, which has been
accumulated in past years and which makes it possible to forecast
the course of events with considerable accuracy. It is a matter of
justifiable pride for the Anti-Locust Centre that in the present in-
vasion every country has received a timely warning, and that these
warnings have proved to be correct.
THE INTERNATIONAL ANTI-LOCUST CAMPAIGN
Seasonal movements of the desert locust cover an enormous region.
Swarms produced during the summer monsoon rains in India fly
in the autumn to southern Persia and Arabia; the latter country
receives about the same time the swarms bred on summer rains in
Africa. The winter and spring rains in Arabia and southern Persia
enable these locusts to multiply and the new swarms produced in
these countries move during the spring into Sinai, Egypt, Palestine,
Syria, Iraq, Central Persia, Afghanistan, and India, sometimes reach-
ing as far north as Turkey and Soviet Middle Asia, breeding wherever
they meet rains. The Red Sea, Gulf of Aden, and even the Arabian
Sea are liable to be crossed by swarms migrating between Africa,
Arabia, Persia, and India. Many swarms from Arabia cross to the
Sudan, Eritrea, and Ethiopia, where they are able to breed again on
summer rains. In the Somalilands, Ethiopia, and East Africa, the
seasons are somewhat different, but the principle remains the same,
since locust swarms always evacuate a region which becomes too dry
and migrate to a rainy one. As a result, the whole enormous region
stretching from East Africa to India has to be regarded as a single
interconnected migration area. Obviously, the general strategy of
the anti-locust campaign had to be based on the knowledge where and
when the enemy could be best attacked. An essential principle of
this strategy was to evolve a single plan of the campaign, with a
view to exterminating locust swarms wherever this can be done with
the maximum effect.
In planning the campaign, it was essential to make full use of the
fact that in many of the affected countries there existed efficient
local entomological organizations. Such organizations in India,
Anglo-Egyptian Sudan, and the British East African colonies could
be relied upon to organize locust control in their own territories,
within the framework of the general campaign. Some of them went
further, and generously offered their assistance to the surrounding
619830—45——_23
344 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
territories. Thus, the Sudan supplied personnel and bait for Arabia;
India sent a trained staff to help in Persia and Oman; Kenya has
undertaken to supply bait to the territories of the former Italian
East Africa, etc. In Persia where local personnel was competent to
deal with the situation, the extent of the operations required was
too great for the local resources, and British, Indian, and Soviet
Governments came to their assistance by providing additional per-
sonnel, motor transport, bait, etc.
The chief problem, however, remained that of Arabia, a vast sub-
continent devoid of communications, with a sparse population, which
has little interest in locusts as agriculture is practically nonexistent.
On the other hand, this is one of the most important locust-producing
areas. Fortunately, most of the peninsula is under the rule of King
Ibn Saud who is keenly interested in the development of his country
and he not only agreed to admit anti-locust missions but offered ready
assistance in their work. Small motorized anti-locust missions were
sent to various parts of Saudi Arabia and Oman in 1942-43, mainly
for the purposes of studying the conditions and acquiring experience
in desert warfare against locusts. The next winter (1943-44) it
became possible with the assistance of civil and military authorities
to send into Arabia several well-equipped missions, comprising over
350 motor vehicles and nearly 1,000 men. These missions were dis-
tributed over all the most important locust-breeding areas and have
accomplished a magnificent piece of work in spite of many and various
difficulties. Most of the personnel were British, but it included also
Americans, Egyptians, Indians, Palestinians, and Sudanese locust
officers and technical assistants. The whole anti-locust army was
technically directed by the Chief Locust Officer (R. C. Maxwell-
Darling, later succeeded as Senior Locust Officer in Arabia by D.
Vesey-Fitzgerald), and various detachments kept in touch by wireless.
Many thousands of square miles of territory, some of it never before
visited by Europeans, have been effectively cleared (by poison bait)
of locusts, which were killed in quantities defying all estimation.
Apart from the immediate achievement in reducing locust hordes,
which would have invaded the adjoining fertile countries, the Ara-
bian campaign had a great propaganda value, showing the population
that locusts, which used to be regarded as Allah’s visitation, can be
killed and crops saved from them. These crops may be few and far
between, but this makes their local value even greater than it would
have been elsewhere. The campaign has also demonstrated the sin-
cerity of purpose of the United Nations in sending the anti-locust
missions. For those who conceived the idea of the Arabian campaign
and who participated in planning and in carrying it out, it was an
encouragement to see that, as it was hoped, locusts can be beaten on
their own ground.
LOCUST PLAGUE—UVAROV 345
Anti-locust campaigns on a similar scale had to be organized also
in East Africa, where military authorities rendered most valuable
help with regard to transport and personnel, while the Royal Air
Force was everywhere playing its part, helping with communications
and transport. In order to coordinate operations in all British terri-
tories and the occupied Italian ones, an East African Anti-Locust
Directorate was established at Nairobi. In Kenya efforts on a par-
ticularly great scale have been made, with the result that the agricul-
tural production of the country, which has greatly increased during
the war, has not suffered to any serious extent. In the past, locust
invasions in East Africa often entailed wholesale destruction of crops
and famine resulted.
A gallant fight has been put up by India, where great difficulties had
to be overcome in order to centralize the direction of the campaign,
since locusts were supposed to be the responsibility of each separate
provincial government, not all of which were equally alive to the
danger. However, good progress has been made and in 1943 a great, if
temporary, victory over locusts was won in India, which by the end of
the year was clear of swarms, but became reinvaded from the west in
1944 when again a successful campaign was carried out. This rein-
vasion served to underline the fact that no country can hope to achieve
a lasting success by its own efforts alone, but all have to work together.
Ethiopia presented a particularly difficult problem. As in the case
of Arabia, many parts of Ethiopia serve for the production of locust
swarms and it was impossible to expect that they would be controlled
locally. Moreover, previous knowledge of Ethiopia in relation to the
locust problem was extremely meager. Therefore, a special mission
was sent to Ethiopia in 1942 with a view to investigate the situation, to
organize regular locust information service, and to work toward making
the authorities locust-conscious. By 1944, it was possible to report ex-
cellent progress in all these directions, but there remained still large
areas where locusts continued to breed but where it was impossible to
organize their effective control. These areas of Ethiopia, as well as
Yemen in Arabia, so far remain beyond the general plan of the cam-
paign, but in both countries there are hopeful signs of improvement.
The organization of a series of campaigns of such magnitude would
have been impossible without the ready cooperation of all governments
concerned, and of the many civilian, military, and air authorities of
the Allied nations. Special credit is due to the Middle East Supply
Centre, an Anglo-American regional economic organization based in
Cairo, with ramifications over the whole of the Middle East. That
Centre, advised by the Chief Locust Officer (R. C. Maxwell-Darling,
succeeded by O. B. Lean), has undertaken to shoulder the heavy bur-
den of organizing and administering the campaigns in Arabia and
346 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Persia, and such successes as have been achieved are largely due to
the efficiency of the machinery which had to translate into action the
plans prepared by experts.
The invasion area of the desert locust, however, is not restricted to
East Africa and the adjoining parts of Asia, but extends across the
French West and North African territories. Here the organization of
control is in the hands of French authorities, and the Allied Govern-
ments are only rendering assistance by supplies of poison. French
experts and the administration are faced with enormous difficulties
in organizing their anti-locust campaigns, but their efforts are meeting
with considerable success. Great progress in the anti-locust organiza-
tion was marked by the establishment in 1943 of the Office National
Antiacridien at Algiers. This office, directed by the outstanding locust
expert, Dr. B. N. Zolotarevsky, aims at coordinating anti-locust meas-
ures throughout the French African territories. A continuous work-
ing contact is maintained with the Anti-Locust Research Centre in
London, and in this way the unity of the general plan is ensured.
The great series of anti-locust campaigns just outlined is far from
being over, and it is too early to claim their success. Nevertheless, it
is significant that, with the invasion in its fourth year, no serious losses
of crops occurred anywhere, in sharp contrast to what happened in
the past invasions by the desert locust. Great efforts were needed to
achieve this result, but their cost must be regarded in relation to the
losses that appeared unavoidable. It should be clearly understood,
however, that this success is only a temporary one, and any relaxation
of effort would lead to a disaster. In fact, the year 1944-45 may see the
peak of the present invasion which will probably continue for 2 to 3
years more, and the campaigns will have to go on until the danger is
overcome. The need for protecting food production in Africa and the
Middle East was particularly urgent during the war, but it would be
a poor introduction to the postwar world if a famine were allowed to
develop on the conclusion of hostilities.
THE CODLING MOTH
By B. A. Porter

Administration, United States Depariment of Agriculture

INTRODUCTION
The codling moth, Carpocapsa pomonella L., is a conspicuous exam-
ple of an insect species that has been able to maintain itself as a
destructive pest of apple orchards for more than a hundred years in
spite of the continuous development and improvement of control
practices. Forty or more investigators employed by the United States
Department of Agriculture, State agricultural experiment stations
and other State agencies, and insecticide companies, are now devoting
all or a considerable part of their time to this problem, and progress
is constantly being made in the development of control measures. The
literature has become so voluminous that no one person has ever re-
viewed all of it. Yet with all of this progress the insect continues to
cause serious losses to apple growers. Since similar trends have been
exhibited by certain other insects, a review of the evolution of control
measures for the codling moth, and the conditions that have permitted
the insect species to maintain itself in spite of these control measures,
may be of interest to students of insect control problems.
BIOLOGY OF THE CODLING MOTH
For the benefit of readers who are not well acquainted with the
codling moth, a brief summary of its seasonal history will be given:
The codling moth passes the winter as full-grown larvae in cocoons,
in crevices in the bark of the tree, under loose flakes of bark, in debris
on the ground, and in similar places (pl. 1, fig. 1). In early spring,
as the buds begin to push out, the insect changes to the pupa (pl. 1,
fig. 1), or stage in which the transformation from larva to adult moth
takes place (pl. 1, fig. 2). The first moths appear about the time the
apple trees come into bloom; and shortly begin to lay their white,
scalelike eggs (pl. 2, fig. 1) on the leaves, chiefly around a fruit spur.
Later many of the eggs are placed directly on the fruit. The newly
347
348 |= ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
hatched larvae make their way to the fruit, unless the eggs were al-
ready there, chew their way in, and feed on the pulp and seeds until
mature (pl. 2, fig. 2). During the first part of the season many of the
worms enter through the calyx, or blossom end of the fruit; later most
of them enter the fruit through the side. The minimum time required
for a complete life cycle under the most favorable conditions is ap-
proximately 37 days. The number of generations in a season ranges
from one, with a negligible fraction of a second, in the more northern
apple-growing sections, to three nearly full generations and a part of
a fourth, in the more southern localities in which apples are grown.
In favorable seasons in such localities, the worm population in late
summer reaches tremendous numbers. In unsprayed orchards there
may be five or more worms in nearly every apple, and the crop is com-
pletely riddled; in many reasonably well-sprayed orchards losses of
20 to 30 percent are not uncommon. Although a few growers may
succeed, worm control is an uphill fight under such conditions, and in
certain localities in which such conditions exist, apple production has
undergone a serious decline
CONTROL BY ORCHARD SANITATION
Until late in the last century, partial control of the codling moth
was accomplished by various practices which are often referred to as
“orchard sanitation,” including the trapping of the mature worms
under bands. The early writers recommended the removal of loose
bark from the tree trunks, the destruction of rough ground debris,
and the removal of dead wood from the tree, in order to destroy the
insects in their hibernating quarters and to eliminate their favored
cocooning places. The removal and destruction of infested fruit, the
screening of packing sheds, and similar measures, were also suggested.
For the purpose of trapping the worms, a number of ingenious types
of bands and other traps were developed during the nineteenth cen-
tury. Banding was first suggested about the middle of the century
(Burrelle, 1840). One of the bands most widely used for a time was
a hay-rope band (Trimble, 1865) (pl. 3). After a few years, however,
this type of band gave way to materials more convenient to use, such
as heavy wrapping paper, burlap, canvas, or flannel cloth. Some
growers who used the cloth bands killed the worms trapped in them
by running the bands through a clothes wringer, mounted on a wheel-
barrow for convenience in operating it and moving it from tree to
tree in the orchard. Then there was the Wier shingle trap which
consisted of three shingles placed on the trunk of the tree, and held
. just far enough apart to furnish an attractive cocooning place. The
worms were killed by rubbing one shingle against another, or by giving
the whole device a sharp blow with a hammer.
CODLING MOTH—PORTER 349
With the advent of spraying, the control measures just outlined—
banding, the scraping of loose bark from the trees, destruction of
debris, and similar practices—became supplementary or were dis-
continued entirely. About 15 years ago, Siegler and associates (1927)
devised a chemically treated band which automatically kills the worms
that enter it. Such bands are now used by many growers. A revival
of the various sanitary measures took place from 1926 to 1935, when
difficulties with spray residues were the most acute. The use of such
measures was, however, still looked on as secondary and supplementary
to spraying.
The predominant development in the codling moth problem has
been the adoption and evolution of spraying.
EVOLUTION OF CONTROL BY SPRAYING
In 1878 the control of the codling moth was completely changed
by the discovery made by two New York State growers that the
recently developed use of Paris green against canker worms was also
giving control of the codling moth. This was reported the following
winter (Woodward, 1879), and in 1880 there were conducted in Michi-
gan the first official experiments with an arsenical, known as London
purple, for codling moth control (Cook, 1880). The favorable results
obtained stimulated extensive experiments elsewhere with both Paris
green and London purple. Early in the twentieth century these ma-
terials gave way to lead arsenate, which in a short time became the
standard material for codling moth control. Lead arsenate was first
available as a paste, often prepared by the grower himself from sodium
_ arsenate and lead acetate or lead nitrate. Soon, however, lead arsenate
became commercially available in a powdered form, which rapidly
displaced the paste material, because of greater convenience of han-
dling. The effectiveness of lead arsenate has been further increased by
the use of various accessory materials, such as fish oil or mineral oil
emulsion. With certain accessory materials the lead arsenate con-
tinues to build up on the fruit and foliage with prolonged spraying,
instead of leaving the tree with the run-off.
The spray programs followed by growers have also undergone a
marked evolution. At first many growers obtained satisfactory con-
trol with a single spray, applied just after the petals fell. After a
few years, however, the need for more spray applications during the
season became evident, and now many growers put on 8 to 10 or even
more applications of spray for codling moth control. Many of the
State colleges or experiment stations regularly furnish the growers
with current information on codling moth development during the
season, to aid them in the timing of spray applications. The use of
traps containing baits of fermenting solutions of low-grade sugars or
350 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
syrups, often with added aromatic chemicals, although not accom-
plishing their original purpose of direct control, have been found
valuable aids to the timing of spray applications, by giving informa-
tion on moth activity and abundance in the orchard.
SPRAY-RESIDUE PROBLEM
In the earliest official test of arsenicals (Cook, 1880) the question
of the effect of the material on the consumer was considered. On the
basis of analyses which were made at that time, the conclusion was
reached that the quantity of poison that could be carried over to har-
vest as a result of the spraying was insignificant. With the type of
spraying that was done in the early days this was probably a correct
conclusion. However, as the number of spray applications increased,
along with increases in the strength of the spray mixture, and in the
number of gallons applied per tree, the quantities of lead and arsenic
on the fruit at harvest constantly increased. The question of dan-
gerous residues was raised from time to time but it was usually dis-
missed with a statement that it would be necessary to consume an
impossibly great quantity of the product at one sitting to obtain an
injurious dose. During all this period the acute toxicity was the only
consideration, but in the early 1920’s there developed a realization
that the use of lead arsenate sprays had increased to a point where
American fruit was carrying quantities of residue actually or poten-
tially dangerous to human health from a cumulative standpoint. The
situation was crystallized in 1925, when British health authorities
rejected shipments of American apples because of excessive arsenical
residues. This episode was followed by appropriate action by the
United States Department of Agriculture in carrying out its responsi-
bility for the enforcement of the Food and Drugs Act. This action
caused consternation in the apple industry, but fortunately effective
washing methods and machinery were promptly developed for re-
moving the residue before the fruit is marketed, which has permitted
the continued employment of lead arenate until other less objection-
able insecticides or other methods of control are developed.
SEARCH FOR NEW INSECTICIDES
The difficulties with spray residues and with worm control in some
localities have led to an intensive search for better and less objec-
tionable insecticides. This search has already proved productive.
Cryolite is effective in the Pacific Northwest, although it is undepend-
able elsewhere, and its use involves something of a spray residue prob-
lem and in many cases washing the fruit is necessary. Nicotine
bentonite has been found more effective than lead arsenate in certain
parts of the Middle West and is used to a considerable extent there
CODLING MOTH—PORTER 351
and elsewhere. Nicotine sulfate with oil is likewise used in some locali-
ties. Phenothiazine, when very finely ground, has given outstanding
control in the Northwest, but has not come into commercial use be-
cause of the unfavorable effects on the fruit and on orchard workmen,
and because of cost. The most recently discovered material is DDT
(2,2-bis (parachloropheny]) -1,1,1-trichloroethane) which may outstrip
all the others, although a final decision on its ultimate usefulness can
be made only after more extensive tests have indicated its effects on
the consumer, on orchard workers, on fruit trees, and on the beneficial
insects that aid greatly in keeping orchard pests within bounds or
that provide for the pollination of the fruit.
DEVELOPMENT OF SPRAY MACHINERY
Along with the evolution of materials and programs for codling
moth control has been the development of spray machinery for the
application of the insecticides. The original hand-operated, back-
breaking barrel pumps soon gave way to crude power-operated outfits
(pls. 4,5). Power spraying equipment has been steadily improved,
coincident with the development of the automobile and airplane. The
grower now has his choice of stationary sprayers, which pump the
spray mixtures from a central plant through overhead or underground
pipes to outlets placed at suitable intervals through the orchard,
standard portable rigs (pl. 6, fig. 1), or the recently developed air-
blast type of sprayer (pl. 6, fig. 2), which delivers the spray by means
of the blast from a propeller similar to those used in airplanes.
Present-day standard spray outfits give pressures up to 700 or 800
pounds per square inch and will deliver 20 to 50 gallons per minute or
more. A number of men can spray at the same time from the larger-
capacity stationary sprayers.
CONTINUED DIFFICULTIES IN CONTROL
With the development of improved spray materials and mixtures,
high-power, large-capacity spray machinery, and carefully worked-out
Spray programs, which all together result in spray deposits on fruit
and foliage that would have been unbelievable 50 years ago, it would
be natural to expect a corresponding improvement in codling moth
control. Actually, however, nothing of the kind has occurred. Al]-
though in most orchards the growers are obtaining a reasonable degree
of control, there is no indication that the worms are any less abundant
or destructive than they were 50 years ago. In fact, in some areas
the growers are having more difficulty than ever before in controlling
the worms. In such areas, in which conditions favor the insect, 20
or 30 percent of the apples are often wormy at harvest time, in spite
of the making of 8.to 10 spray applications during the season, and the
352 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
?
use of supplementary control measures. It is therefore evident that
the codling moth, instead of being a more or less fixed quantity, and
subject to reduction in numbers, as control methods have been im-
proved, has undergone an adaptation or evolution that has permitted
the insect to hold its own or even to increase in numbers in spite of
man’s efforts.
CHANGES IN CONDITIONS
First, the standards by which control is judged have been modified
from time to time. With the trend toward the concentration of com-
mercial apple production in areas remote from markets, only high-
grade fruit is worth the cost of shipping thousands of miles, and in
such areas moderately injured fruit, which in localities near the con-
suming centers might bring fair prices in local markets, is now a total
loss. Also, the American public demands a higher standard of per-
fection in its fruit products than ever before. This all means that our
standard of satisfactory control is much higher than it was 50
years ago.
Many of the practices adopted by fruit growers have given advan-
tages to the codling moth. Apple production has passed from small,
isolated farm orchards to more intensive production in limited areas.
In these newer areas conditions are sometimes especially favorable for
the apple crop, but in other cases there has been extensive promotion
of apple culture outside the range within which the apple would nor-
mally thrive. In either case, this trend has been an important factor
in favor of the worms. With an abundance of its favored food avail-
able in virtually continuous, extensive acreage, with improved varieties
and cultural methods that have to a certain extent eliminated the
biennial bearing habit that characterized many of the older apple vari-
eties, a factor that automatically held the codling moth population at
a low point, it is not surprising that the present-day grower has to
deal with a more numerous population. As these areas have come into
full bearing, the mature trees have often reached such size that spray
coverage has been poor.
The benefits derived from the extensive use of insecticides have un-
doubtedly been offset to some extent by their unfavorable effect on the
abundance and activities of parasites and predators of the codling moth.
Evidence has been obtained in New York State (Cox, 1932; Collins,
1934) that one of the most important larval parasites of the codling
moth, namely Ascogaster quadridentatus Wesm., is adversely affected
by lead arsenate and that in sprayed orchards the percentage of para-
sitization is less than half of that existing in unsprayed orchards. It is
not at all improbable that the effectiveness of other parasites and per-
haps predators is also very much reduced by the continued use of lead
arsenate. This factor may have been an important one in permitting
CODLING MOTH—PORTER $50
codling moth populations to get out of hand in certain localities.
Closely related is the effect of other present-day orchard practices on
the parasite population. It may well be that the intensive clean-cul-
ture or cover-crop systems followed in many modern orchards may
have eliminated many of the other hosts of the common parasites of the
codling moth, thus causing the balance to swing in favor of the codling
moth,
ADAPTATION ON THE PART OF THE CODLING MOTH
The factors just outlined, however, are not sufficient to explain the
marked increases that have developed in the ability of the codling
moth to thrive in the presence of heavy deposits of lead arsenate.
Some change seems to be taking place in the insect itself that is modi-
fying its ability to enter fruit in spite of the presence of a poison.
The most extensive study that has thrown light on this problem has
been carried on by W. S. Hough, of the Winchester field laboratory
of the Virginia Agricultural Experiment Station. His earliest work
(Hough, 1929 and 1934) included a comparison of codling moth stocks
from near Grand Junction, Colo., where the insect had become notori-
ously difficult to control, with stocks from Virginia, where control was
much easier. Dr. Hough showed that newly hatched codling moth
larvae from Colorado stock were able successfully to enter fruit heavily
sprayed with lead arsenate to the extent of 15 to 40 percent or more,
whereas the proportion of native Virginia larvae entering similarly
sprayed apples was usually less than 5 percent. Further, this differ-
ence persisted through 14 or more generations reared in the insectary
under Virginia conditions. Crosses gave intermediate results. Hough
later (1943) found that Virginia larvae from stocks from orchards
having a history of intensive spray programs were able to enter sprayed
fruit in much greater proportion than those from unsprayed or poorly
sprayed orchards. Strains from various Virginia orchards fed through
successive generations in the insectary on sprayed fruit became differ-
entiated from the parent strains, and showed increased ability to enter
sprayed fruit. Steiner and associates (1944) have shown similar
wide differences in codling moth stocks from different orchards in
the Ohio Valley with respect to their ability to enter sprayed fruit.
Both of these investigators have found that this condition is not re-
stricted to lead arsenate, but that differences, although not always so
wide, exist with respect to other insecticides, including nicotine ben-
tonite and cryolite. Hough has reached the conclusion that these
differences are due to differences in general vigor, but Steiner’s obser-
vations have suggested that they may result from differences in habits.
Both of these workers believe that the different strains have been
segregated by the elimination of those larvae that have the least
ability to enter sprayed fruit, rather than that individuals have be-
354 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
come immune or resistant to specific compounds and that such immu-
nity or resistance has been transmitted to their offspring.
Increased ability to survive in spite of insecticide treatment has
been exhibited by a number of different insects, including the Cali-
fornia red scale, Aonidiella awrantii (Mask.), certain strains of which
are much more resistant than others to fumigation with hydrocyanic
acid. The tendency toward the segregation of races within economic
species has been thoroughly reviewed by Smith (1941).
The evidence just cited indicates that, instead of remaining con-
stant and static while the evolution of control measures was going on,
the codling moth as a species has undergone considerable adaptation
or evolution on its own account in the direction of greater ability
to survive in the presence of insecticides. The segregation of resistant
strains, together with certain practices on the part of the fruit indus-
try, have permitted the insect to maintain its position as the most seri-
ously destructive pest of the apple in spite of the development of
control by insecticides to a high degree of efficiency, at least in the
application and maintenance of heavy deposits of insecticides during
the periods when needed. The codling moth is only one of the several
insect pests known to have undergone development in this general
direction, and many other insects may be developing in a similar
way, but at a slower rate. It is evident that ultimately insecticides
or other control measures that are less selective in their action will
have to be used for the control of the codling moth, or perhaps the
problem can be solved by occasional changes from one insecticide to
another that is selective in a different way. Whatever the eventual
solution of the problems that have grown out of the evolution under-
gone by the codling moth, the entomologists will undoubtedly be able
to meet this challenge to their ingenuity and resourcefulness, and
any solution of this particular problem may point the way to means
of meeting similar problems with other insect pests as such problems
arise.

GRASSLAND AND FARMLAND AS FACTORS IN THE
CYCLICAL DEVELOPMENT OF EURASIAN HISTORY?
By J. RUSSELL SMITH
[With 1 plate]
This paper might be called a study of equipment eras—or the inter-
acting influences of equipment and culture in certain environments.
Man is a tool-using animal, and there is a tendency to confuse the
results of mental or personal qualities and the results of the equip-
ment that we may have at hand. Consider for a moment a group of
European primitives, so-called, who left cultural and skeletal remains
in caves of France some 20,000 years ago. Anthropologists have
named them Cromagnon. If they were living today most of us
would doubtless call them savages, regard them as inferior beings.
Sir Arthur Keith tells us that the Cromagnons had larger brain pans
than we have. But we of this generation have inherited agriculture
with its crops and beasts, also engines and machines, transport and
buildings, and books, the master tool, the mother of tools.
It is easy for us in our inherited cultural riches to lose sight of the
scanty cultural inheritance of Cromagnon man. He and his parents
were living in the collector stage of economics. He plucked his living
from the natural environment with the aid of his fingers, toes, and
teeth, and with equipment of wood, fire, flint, shells, bone, sinew, and
skins—Stone Age we call it. He ate everything that was digestible—
beast, birds, fish, reptile, and insect, seed, leaf, stem, and root, and
sometimes the neighbors, but that was usually ceremonial. He prob-
ably lived a life filled with terrors and what we would regard as
impossible hardship.
It is one of the greatest achievements in human history that Stone
Age man made some sort of living in every continent except Ant-
arctica. Archeologists and anthropologists trace Stone Age man from
shores of the Arctic Sea in Greenland to the chill and reeking wet-
ness of Tierra del Fuego; from Alaska to Newfoundland ; from Gibral-
tar to Kamchatka; from the Siberian Tundra to South Africa, Tas-
mania, and the far islands of the Pacific. Stone Age man made a living

Not only did Stone Age man make a living, such as it was, in every
type of environment—he and the women supported their offspring,
maintained the race, formed communities, developed rules of conduct
GRASSLAND AND FARMLAND—SMITH 359
(laws if you like), and created a literature in the form of folklore.
They struggled with external nature, and, like the rest of mankind,
with human nature.
These men and women in the smoky cave, the pit house, the skin
tent, or merely sleeping in the open by fire or without it, were vexed
by two problems that vex us today—the struggle for possessions and
the lust for position, preferment, power.
Howard H. Brinton, a living Quaker writer of distinction, says:
“Every one has within himself, a potential Hitler as well as a poten-
tial St. Francis.”
With these two types in mind we should note that man’s progress
depends upon two things—first, keeping down his own potential Hit-
ler, with the aid of education, morality, and religion; and second,
fighting down his neighbor’s Hitler. Controlling one’s neighbor’s
Hitler presented a social problem, and for this man probably was
forced to invent government.
In the Stone Age, as now, the external Hitler tendency, the bully,
had to be kept in check. Control doubtless began as family fights
and grew into clan, tribe, and other forms of group control. Even in
prehistoric times, government, formal or informal, developed in all
climes, in all societies, and in well-nigh myriad forms.
When man lived by collecting, only a few people could live together
in any one place. Population per square mile was limited by the
amount of available food. One group could force another group out
of hunting grounds, but one group had difficulty in governing other
groups. The political group, if one may use the word, was small.
Although government may have been invested only in family, clan,
or tribe, or in a village group, primitive government usually was
inclusive in the scope of its control over individual freedom. Have
not the elders of all generations said, “We do it this way”? Anthro-
pologists are emphatic concerning the conservatism of primitive man.
That is certainly one reason why the Stone Age lasted so long—long
enough to achieve its amazing uniformity of tools and economy and its
world-wide distribution, despite difficulties of travel.
Many anthropologists believe that this almost static period of human
history may have existed for 500,000 years since our ancestors first
began to use tools, and year by year the anthropologists are lengthening
this period.
A new era began with the use of domesticated plants and domesti-
cated animals. When some 97 or 98 percent of the half million years
of human history had passed, perhaps 10,000 or 15,000 years ago,
changes began to happen. Men and women, or perhaps we should say
women and men, began to plant seed and to grow and cultivate crops.
It is possible that the period of primitive crop growing is much older
619830—45——24
360 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
than that. It was common in five continents. With amore stable and
dependable food supply, human beings could settle down in a village
for most of the year, or even, in rare instances, for a period of years.
Soil exhaustion usually brought declining yields and a new patch was
brought under cultivation. This process was repeated until finally the
entire village had to move to fresh land.
Patch farming was a great improvement over the collecting economy.
It permitted a larger village group and lessened the need to move from
place to place. Patch farming gave new leisure, more time for mind

to play upon mind. Nevertheless, the problem of soil fertility usually
kept the settlement from becoming a large one. It also prevented the
group from remaining at the same place for any great length of time.
These conditions existed on most of the soil areas of the world.
Patch farming was followed by the domestication of animals, espe-
cially in Egypt, the Near East, and Central Eurasia. The tough
shoulders of the ox and donkey began to drag man’s burdens for him
some 6,000 years ago in Mesopotamia. The sheep and goat gave skin
and flesh by herding instead of hunting. These animals also gave milk,
as did the cow. The tamed offspring of the wild boar gave roast pork,
GRASSLAND AND FARMLAND—SMITH 361
and the hen gave eggs without man having to seek the nests of wild
birds in the forest. The new environment produced by the stimulus of
crops, domestic animals, and larger residence groups seems to have pro-
duced a mental emancipation that gave new freedom to the inventive
type of mind.
‘A NEW ERA, BASED ON LARGER HUMAN GROUPS, HAD ITS ORIGIN IN
THE PERMANENT FERTILITY OF THE IRRIGATED VALLEYS OF EGYPT,
MESOPOTAMIA, AND THE INDUS
In Egypt, Stone Age man found that the recurring floods fertilized
his land each year with a thin but rich crust of mud. As a result he
could stay in the same place generation after generation. Large settle-
ments soon developed.
This was something new in the world. Revolutions emerged from
it. Gradually many little governments came under one ruler, the gov-
ernmental unit grew until finally the prowess of one ruler brought all
Egypt, with it millions of people, under one government. For 6,000
years the Nile Valley has continuously supported its heavy population
by benefit of the annual automatic deposit of mud. The Nile is the
most regular, most orderly, most easily usable large river in the world.
It has well earned the affectionate name of “Father Nile.” Large
areas of swamp along its upper reaches become automatic reservoirs
that tame the sudden floods that trouble the lower valleys of most
rivers.
The fertility of the irrigated lands along the Tigris and Euphrates
was replenished in somewhat the same way. But, as compared with the
Nile, the Tigris and Euphrates are wild and disorderly rivers. They
have no controlling reservoirs. The maintenance of irrigation in
Mesopotamia required more labor than in Egypt, and a continuously
effective social organization was necessary. Like Egypt, Mesopotamia
supported heavy populations, towns, cities, kingdoms more than 5,000
years ago.
The recent excavations of Mohenjo-daro and neighboring cities
on the lower Indus show somewhat similar developments about the
same time. These three populous valleys supported themselves by ir-
rigation on wide-spreading alluvial lands with a dry, warm climate.
Man has not yet imagined better conditions for agricultural production.
In these hot, dry valleys men lived under the compulsion of the need
to work their crops in a season of flowing water, and under the near-
compulsion of leisure in the season of drought. There was also the
further compulsion of governments. These factors of surplus food,
leisure time, large business enterprises, the desire for self-expression,
and the compulsion of strong government produced writing, libraries,
codes of laws, pyramids, and temples—cultures that were in many
362 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
respects much like our own. Among factors of production, we should
not minimize strong government—witness the pyramids, a burst of
energy covering only 150 years out of 5,000.
It is now generally agreed that the wheel and axle, the cart and the
beast-drawn plow were first used somewhere between the Persian Gulf
and the Syrian shore at or about 4000 B. C.—perhaps earlier. It is
further agreed that this important invention was made only once
in human history. The spread of the wheel and axle to all continents
has been definitely traced from this one source.
Archeologists are continually finding proof that commerce existed
at this early time between Egypt, Mesopotamia, and the Indus Valley.

FieuRE 3.—Wheat culture in antiquity. (After Carl Bishop.) Wheat had
climatic limitations to its spread. It does not thrive in the wet Tropics.
Because of these exchanges these earliest centers of heavy population,
cities and city culture may legitimately be considered one civilization
in a sense similar to our use of the term Western Civilization.
This new culture of the three valleys with its stupendous advance
over previous cultures was, at base, a result of the enduring soil
fertility. For the first time in human history large sedentary popu-
lations could depend upon the permanence of their food supply.
Generation after generation men could live in the same place. They
could accumulate things. They had leisure. When they learned to
write, they soon recorded knowledge and built libraries in which to
store it. Thus three dry valleys became the cradles of civilization
GRASSLAND AND FARMLAND—SMITH 363
and finally the teachers of the human race. From this base many cul-
ture elements have spread to all parts of the world. It is fortunate
for those of this generation that the Mesopotamians wrote on endur-
ing tablets of clay.
Then, as now, men who traveled carried with them ideas, techniques,
and various culture elements. A trail of fragments of painted pottery
leads from Shushan, near the eastern edge of Mesopotamia, and marks
the road by which culture elements went from Mesopotamia to China.
Through this dry land a natural road proceeds from oasis to oasis.

natural refreshment stations exist. No one knows how long these
little Niles have been feeding humanity. These fertile spots en-
courage travel across Iran, western Turkestan, and eastern Turkestan.
Thence the trail continues eastward across Mongolia and down the
Wei River valley, past the present city of Sian and on to the great
bend of the Hwangho at the southwest corner of the province of
Shansi.
No one knows when culture elements first began to pass northeast-
ward from Mesopotamia over these stepping stones of fertility. This
seems to make logical the Chinese claim that Chinese civilization had
its origin in the Sian Valley near the great bend of the Hwangho.
364 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
This Sian Valley was the first place at which this route across moun-
tain and desert delivered culture elements from the west to men
living in good farmland.
This first center of the present Chinese culture had a rare combina-
tion of qualities. There was enough rain to support agriculture,
and there was loess soil. This wind-blown gift of deserts that lay
to the west is the closest approach on earth to the perennial fertility
of the annually flooding river valley. Let a farmer plow the top foot
of loess and let the soil wash away or blow away, it matters not—
the second foot is as good as the first; the twentieth foot is as good as

the second. Here then was another basis for an agriculture that
could endure for centuries.
Generation after generation of men in the Wei Valley loess had the
advantages of permanent fertility of the soil. Meanwhile the mind
of man was fertilized by the arrival of cultural elements from Meso-
potamia and the steppes. Still another stream of culture elements
came to the Sian Valley from India, by way of the Burma Road.
Sinologists say that fowls and rice were early arrivals over this route.
Besides the fertility base of loess vouchsafed by nature, the farmer
adopted two fertility measures whose effectiveness is unrivaled by

anything outside the three great valleys. The Chinese method of
cultivating rice in the paddy fields conserves soil perfectly and adds
a touch of fertilizing mud. The other fertility device is that of col-
lecting human excrement and returning it to the land. The Chinese
have systematically applied this device for many centuries. It is
well-nigh impossible to overestimate its importance as a means of
support to Chinese civilization. Thus, fertility, enduring or pre-
served, stands out as the basis for the development and endurance of
the Chinese civilization. These factors gave to these people the
combination of time and continuity similar to that which accompanied
the rise of cultures in Egypt and Mesopotamia.
The Chinese received many culture aids from the outside, but they
devised their own system of writing and made many important inven-
tions on the basis of their own native wit and the stimuli from the
ancyiciser

Near East and India. China may be regarded as one of three subse-
quent cultures that leaned heavily in their beginnings on culture ele-
ments from the three great irrigated valleys.
Culture elements traveled northwestward as well as northeastward
from the centers of its beginning. Between 2000 B. C. and 1400 B. C.
the Island of Crete was one of the most highly civilized places in the
world. There is evidence that the people of Crete learned from the
people of Mesopotamia by way of Anatolia and the stepping stones
furnished by the Aegean Islands. Knowledge also must have traveled
by direct voyages to Egypt, only 340 miles distant, there is so much
evidence of interchange between the isle and the Nile.
The Aegean culture was spreading from island to island, and had
produced the famous cities, Tiryns and Mitylene, on the mainland of
Greece, whose cultural remains, so unlike those of the Classic Greeks,
366 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
were long a puzzle to archeologists. Knossus, the ornate and learned
capital of Crete, was destroyed about 1400 B. C., nearly 3,400 years ago,
but that date was more than 2,000 years after the Sumerians had
developed a complicated civilization and were filing away its amazing
records on their durable tablets of clay.
While culture was spreading outward from its places of origin
something was brewing in the grasslands of central Eurasia—that vast
unbroken plain that stretches from the Carpathians to the Altai and

This vast grassland was an inhospitable area for the Stone Age man
before he had domestic animals. There was grass, of course, on most
of its extent, and fleet-footed game. But wood and natural shelter
were scarce except along the mountain and northern forest borders
and along the banks of the few streams that crossed the plain. The
patch farming of Stone Age man was largely limited to these spots
GRASSLAND AND FARMLAND—SMITH 367
in the vast plain, such as the banks of the Oxus, Syr Darya, Don,
Volga, and other rivers that were favored with wood, water, and
possible garden patches.
A new and very different era began when the man of the plains got
sheep, goats, cattle, and, lastly, the horse. The steppe people domes-
ticated the horse (E. A. Speiser, of the University of Pennsylvania,
concurs), and it became thoroughly integrated into every feature of
the life of the people of the steppes. A new force, a new dynamic
had appeared upon the Eurasian scene—the man on horseback. Here
was revolution. It upset the affairs of man and was far reaching in
its effects. Indeed, the man on horseback has had but two analogs in
human affairs—steam transport and the airplane.
Carl Bishop, of the Freer Gallery of Art in Washington, says that
the Indo-European languages were developed by these horse-using
people on the steppes somewhere in southeastern Europe or south-
western Asia. He further states that these people whom we call Indo-
Europeans had the word for wheeled vehicle before they separated
into eastern and western groups. Louis H. Gray concurs.
These Indo-Europeans of the steppes and the horse-using Turanians
who appeared later in the same area, have profoundly influenced the
history of Europe and Asia, both as spreaders of culture and as de-
stroyers of states and civilizations. It is as destroyers that they made
their conspicuous contribution.
The grassland nomad lives by flocks, the flocks live by grass. Ani-
mals must move to obtain grass, and man must move with the animals.
The nomad has mobility—here today, gone tomorrow—and mobility
is a very important factor in warfare. It is also a sad fact that the
grassland can produce more men than it can feed. Thus there exists
the expulsive force of hunger. These factors make migration so easy as
to be almost a part of the social organization. Many will be familiar
with Ellsworth Huntington’s thesis to the effect that periods of
drought and scanty grass made an expulsive force that sent Central
Asian nomads to overrun surrounding lands. Farmer peoples living
east, west, and south of the Eurasian plains had abundant and oft-
repeated cause to mourn the fact that such a region as the Eurasian
grassland existed.
About 2000 B. C. bands of nomads from the steppes began working
their way around the western end of the Black Sea and southward
through Thrace and into Greece. They were shepherds accompanied
by their flocks and with rude carts loaded with household goods and
drawn by oxen. These people later became the ancestors of the Classic
Greeks. By 1400 B. C., or in about 600 years, these shepherd migrants
~had learned from the more cultured Aegeans to build ships. In their
ships they sailed to Crete and conquered it. These barbarians burned
368 § ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
the palaces, libraries, and temples of Knossus. Those of the learned
and cultured Cretans who could do so fled in ships to the still civilized
shores of Asia Minor, Syria, and Egypt. ;

While the Greeks in the second half of the first millennium B. C.
were driving civilization back toward its center, others of the Indo-
Europeans of the steppes had passed north of the Caspian Sea and
entered the plateau of Iran. They lingered there for generations—
GRASSLAND AND FARMLAND—SMITH 369
long enough, according to Prof. Louis Gray of Columbia University,
to produce the literature known as Vedas. They then divided, one
group went southwestward into Mesopotamia and the other southeast-
ward into India. This common origin in the steppes explains the
remarkable similarity of the Greek and Sanskrit languages.
Beginning about 1200 B. C. many waves of these Aryans went into
India. They overwhelmed the Indus Valley cultures. Prof. Walter
Von Brunn, of the University of Leipzig (Science News Letter, Feb.
19, 1938), pointed out in 1938 that the remains of Mohenjo-daro,
Chanhu-daro, and other Indus Valley cities of 3500 B. C. had no signs
of having had walls or other fortifications. From this fact he inferred
that continuous peace prevailed in the era before the eruption of the
horsemen from the steppes. Perhaps this was the Golden Age.
These cities on the Indus plain had houses of well-burned brick.
The present inhabitants of this area live in mud villages. Fifty-five
hundred years ago Mohenjo-daro, built of brick, had a sewer system
equal to that of Pompeii and other Roman cities that were built more
than 3,000 years later.
All this the northern invaders destroyed—destroyed it so com-
pletely that we only learned of its existence by accidental discoveries
in the twentieth century. Imagine if you can the thoughts and feel-
ings of the cultured people of Mohenjo-daro as these early Nazis
destroyed a city that had stood for centuries in peaceful prosperity.
India received many waves of these new raw men from the steppes.
As a result Indo-European languages prevail today over large areas
in northwestern India. The other results of these migrations can
be observed today by anyone who passes northwest from southern
India to the Khyber Pass and observes the gradual change in the
color of the skin of the inhabitants. The color of native skin is black
in southern India, white in the Khyber Pass, with various shades
between.
The culture that originated in the warm and fertile valleys spread
eastward to China, westward to the Aegean, and also, at an early
date it spread northward to the highlands of Iran and Armenia
where, as in China and in Crete, a civilization arose in part on bor-
rowed culture elements.
In the third millennium B. C. non-Indo-European peoples in what
we now call Armenia had a considerable culture, with cities and
written language. Babylonian colonists settled among them, and
the Mesopotamian cuneiform characters were added to their writing.
Early in the third millennium there came among them a migra-.
tion from the steppes, “an Indo-European conquering people called
by us ‘Hittites.’” The invaders stayed, learned, increased, and made
an empire. Recent excavations show that Hittite scholars mastered
370 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
six languages and were in “no way inferior to the Babylonians and
Egyptians” (Encyclopaedia Britannica). Hittite armies conquered
Babylon.
In 1685 B. C. a band of people called Hyksos, whose leaders are said
by Speiser to have come from Turkestan, organized an army in the
Hittite area and proceeded to conquer Egypt. This expedition took
the horse to Egypt for the first time. The horse-drawn chariot of
the Hittites was an early kind of “blitz” warfare. It overwhelmed
the Egyptians, perhaps with the aid of better bronze for the cleaving
of skulls.
At this point in our narrative the record stands as follows: four
civilizations—Crete, Indus, Mesopotamia, Egypt—overrun by the
horse-using Indo-European barbarians from the steppes. It was
indeed fortunate that the seed of civilization was not destroyed by
these conquests. ,
The Hittite empire fell before the next wave of Indo-Europeans,
horsemen from the steppes. These were called Phrygians. These
horsemen entered Asia Minor by way of the Hellespont. Like the
Greeks at Knossus the Phrygians destroyed so well that it was only
at a recent date that we knew much about them, and only in a very
recent day that scholars deciphered the Hittite writings. Fortunately,
these people wrote on bricks of clay, rather than the perishable and
ephemeral rubbish on which we write so voluminously.
This episode of the Hittites can almost be considered the West
Asian history cycle type, a type that is repeated through several mil-
lennia. Witness its operation in another group—the Scythians.
Herodotus described the Scythians (sometimes called a tribe of
Cimmerians) as being nomads of the steppes north of the Black
Sea. The Scythians followed their flocks on the open steppes in the
summer, back to the shelter of the wooded stream banks in winter.
The men rode horseback with their trousers—a steppe invention—
tucked into their boots—another steppe invention. The women rode
in wagons. The details of their life sound strangely like those of the
present-day Kirghiz of Central Asia. Horse flesh and mare’s milk
were standard articles of diet. The abode was a tent of felt.
In the seventh century B. C. there was much movement of peoples
on the steppes. “The Scythians overran and frightfully ravaged
wide areas of Central Asia and Eastern Europe” (Bishop). Some
crossed the Hellespont into Asia Minor, which they ravaged, and
where they stayed for a century. Some went somewhat farther east
and developed a kingdom in Ecbatana, within the present kingdom of
Iran. Thus strengthened, refreshed, and multiplied, but still full of
the barbarism of the plains, the Scythians harried the Assyrian king-
dom, destroyed Ninevah and other cities, and advanced to the gates

The Indo-Huropeans dominated northern India and even Burma so thoroughly as to leave their language. The
original Dravidian speech holds the south of India and an island of Munda-Mond-Khmer (Indo-Chinese) holds
out in the Ganges Valley. The Sino-Tibetan has pushed down and crowded Munda-Mond-Khmer into a
corner.
The Turco-Mongol-Tungus group has pushed the Japanese group into corners on the east and cut the Indo-Huro-
pean areas in two on the west. The Hamite-Semite has a crowded Indo-European in the Mesopotamian area.
The Arabs left Islam in Ivan but not their language.
The Indo-European block holds nearly all Europe except the Finnish area, the Hungarian remnant, and the
Basque and Caucasus areas. The Caucasus Mountain area seems to have been an island of human refuge
in the sea of migrations. It contains much linguistic and human flotsam and jetsam. It is said that 72
languages are spoken in Tiflis.

GRASSLAND AND FARMLAND—SMITH 371
FicureE 11.
Ficures 10 anp 11.—This record from an old Chinese tile tells us why the Chinese
built the Great Wall. A new blitz had come from the grassland. The horse-
man with the two-piece bow seems to have been well nigh irresistible on open
land, hence the wall. (After Carl Bishop.)
372 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
of Egypt. The Scythians then disappeared from history—probably
absorbed. But note the evolutionary steps. A horde of nomads had
left the steppes, harried the plateau. They tarried for a few gen-
erations. Almost surely their numbers increased, and they mustered
strength in that land of better pastures and scattered oases. They
then moved on to a career of conquest and rapine in the fat lands and
rich cities of the plain. Then the melting pot absorbed them. That
is the cycle. It occurs and recurs through nearly 3,000 years B. C.
and plenty of times later.
The exploits of the Medes and Persians and of the Macedonians,
conquerors all of Babylonia, fit closely into this pattern. The horse,
the most spectacular contribution of the steppes, has played a curious
and striking part in man’s affairs in Eurasia. Bishop thinks that the
Scythians may have been the first effective cavalrymen. Armed with
a compound bow, which seems to have been an invention of the
north, a cavalryman could ride circles around a charioteer. Hence,
the use of chariots in war declined in the Near East after the Assyr-
ians, in the ninth century B. C., adopted cavalry from their enemies,
the Scythians.
Man’s experience in learning to use the horse serves to illustrate the
stupidity of man rather than his cleverness. Perhaps most persons
have thought of the horse in ancient history as a beast of burden,
drawing the plow, the cart and the wagon with supplies for home or
the army, with gentlemen and generals riding on comfortable saddles.
Not so. It is now known that the first important use of horse in
harness in the Near East was a thousand years at the war chariot.
For this service it was speed that counted, not ability to draw heavy
loads.
The chariot was distributed to Ireland and Korea between 2500 and
1000 B. C. After centuries of using the chariot as an instrument of
warfare men began to fight from the back of the horse. But it was
more centuries before the stirrup was invented. Moreover, man used
the horse in harness for more than 3,000 years before a method was
devised whereby a horse was fastened to a wagon by means of traces.
Only then could a horse pull with more than a small fraction of its
strength.
The shoulders of the ox and donkey are higher than are the necks.
These beasts with yokes upon their shoulders or upon the head of the
ox, pulled the plows and wagons of antiquity. The anatomy of the
horse does not encourage yoking. Nevertheless the ancients fastened
the yoke to a band around the neck of the horse. If the horse pulled
with a considerable fraction of his strength the band pressed upon
the windpipe and jugular vein and choked him down. This harness
also held his head high, but when a horse pulls a load he puts his
GRASSLAND AND FARMLAND—SMITH 373
head down. Pictures of war chariots show they did not carry much
load, and Roman records verify.
Early uses of the horse sift down to this—meat supply, milk animals,
assistant to the herdsman, the pet of princes, for pageantry, religious
ceremonies, and war—especially war.
The horseman with a two-piece bow was the greatest “blitz” before
gunpowder. This bow seems to have brought cavalry to the fore.
The horseman with a lance was not so potent. This bow brought
the horse to his Golden Age, to his zenith as an influence in the affairs

of man. From the beginnings of cavalry with the Scythians, about
the ninth century B. C., to the date of the effective use of gunpowder,
more than 2,000 years later, the cavalryman of the Eurasian grasslands
almost continuously harassed the settled cultures upon the grassland
rim and often smashed them at will. Thus the horse, the great contri-
bution of the Eurasian grasslands to history, had several millennia
during which his relation to sedentary societies was not primarily in
the field of economics, but in the field of war; not primarily at defense,
but rather the war of offense. The horse was an instrument of con-
quest and destruction of peoples, cities, governments, and social
organizations.

In the Chou kingdom in China, 1000 B. C., the minister of war was

Taxes were collected in kind, and the chief tax gatherers were known

continents kingdoms were measured by the number of chariots they
could put in the field. (See King Solomon.)
A recent writer, Bates, emphasizes the acute shortage of power
among the Romans on both sea and land. This power shortage led

to do other drudgery on land. Bates alleges that Roman wars were
often little more than slave-gathering expeditions.
In the ninth century A. D., someone, apparently in France, invented
the horse collar and traces. A horse could then pull a load. Then,
as Mr. Bates tells us, horses could really work and enter the economic
realm. Horsepower became cheaper than slavepower, and slavery
gave way toserfdom. As mechanism improved, serfs became freemen.
Inventions gave man equipment that permitted him to emerge from
the slave age. At a much earlier time inventions had ushered in the
Stone Age. Most important inventions change man’s relation to some
part of the earth.
GRASSLAND AND FARMLAND—SMITH 375
The horse, especially the horse bearing grassland man upon its
back, seems to have carried destruction to ancient societies in a way
that suggests a strong resemblance to the work of the airplane today.
CHINA AND ITS RELATION TO THE GRASSLAND
The relations of China with the grasslands of Central Asia fall into
two epochs. In the first epoch China received culture elements. In
the second epoch China received conquerors and destroyers.
Considerably before 8000 B. C. Babylonia had a well-developed
culture which included writing and a complete mastery of work in
bronze. Babylonia also had wheeled vehicles, ox-drawn plows, wheat,
many other crop plants, and all the common domestic animals except
the horse (Bishop).
There is no evidence that China had knowledge of metals before
2000 B. C., but 500 years later peoples ruled by the Shang Dynasty
in the central and lower Yellow River basin had a mature and devel-
oped system of writing, evidently homegrown. These peoples also
had a skilled technique for working in bronze. Bishop says, “Bronze
working was carried to a pitch of technical and esthetic excellence
hardly if ever equalled in later times in any land.” Much of this
craftsmanship was undoubtedly borrowed, together with many plants
and animals, from the Near East. It had taken the Mesopotamians
several thousand years to develop these things.
Before Chinese contact with the Near East, the Stone Age man of
the loessial area on which Chinese culture is believed to have devel-
oped, was a sedentary agriculturist. He lived, at least for the colder
part of the year, in a pit house which gave unusual opportunity for the
preservation of archeological records. These pit dwellers had dogs
and many domesticated pigs. As early as the fifth millennium B. C.
they cultivated millet and some leafy plants (Goodrich).
There is no sign of fortification about their villages until culture
elements from the Near East appear—sheep, and bronze or copper
arrow tips. The need for defense had come. The villages of the pit
dwellers now have earthen walls. These tillers of the loessial lands
are learning unpleasant things from the west whence they had de-
rived so many useful things.
About 1050 B. C. (according to Bishop), the Shangs were con-
quered by the Chous, assisted by rebellious Shang subjects. The
Chous came in from inner Asia—conquerors from the grasslands.
Ellsworth Huntington will smile with satisfaction at the mention
of the Chinese tradition to the effect that the Shang Dynasty came
to its end during a period of protracted drought for which the king
was held responsible because he neglected to observe the proper rites.

Bishop states that the conquering Chous had a culture much like that of
the Aryans who invaded India about 1200 B. C. About this time,
also, other outsurges of steppe peoples went into Europe, southwest
Asia, and Egypt.
Shang refugees fleeing before men from the grassland carried their
culture eastward and southward to outlying regions hitherto bar-
barous. This oft-repeated process of culture spreading is now being
again repeated as the educated Chinese from the westernized east
coast of China move their colleges and industries to the conservative
western uplands to escape the Japanese destroyer.
In the first millennium B. C. this process of grassland invasion and
eastern culture dispersal was repeated several times. The unifica-
tion of many kingdoms into one Chinese empire is commonly attri-
buted to the fact that about 300 B. C. one of the western kings adopted
a new technique of warfare from the barbarian enemies of the steppes.
This was the mounted bowman with the two-piece bow (fig. 11)—an
irresistible blitzkrieg much superior to the lumbering chariot, the
preceding blitz.
The Great Wall of China rose as a tribute to the marauding horse-
men of the steppes. One might almost say it is a monument to the
horse. This, the greatest structure in volume reared by man, was
built steadily during the seventh, sixth, fifth, fourth, and third
centuries B. C. and often thereafter even as late as the middle of the
eighteenth century A. D. Although the wall was designed to keep
the nomad of the steppes out of the farmlands, it was only a limited
success as is Shown by the conquests of China by Tatars, Mongols, and
Manchus. These cavalrymen from the steppes could conquer China.
They spread terror and rapine and made periods of chaos. The con-
querors established dynasties. The dynasties melted away. The
Great Wall still remains, 1,400 miles of it, in varying degrees of decay
or ruin. But the nomad conquerors that rode through the wall in
shouting triumph have disappeared completely, having been absorbed
by the great mass of the Chinese people. Meanwhile the Chinese
peasant still keeps on with his not yet so greatly modified neolithic
type of agriculture.
ROME AND THE NOMADS FROM THE EAST
The unfortunate experiences of the late Roman Empire with the
seminomadic Germans and the Huns (Turanians, not Indo-
Europeans) of Asia and Mongolia are a standard part of school his- —
tory. Bands of marauding horsemen, recognizing no law but the
power of conquest, came out of the land north of the Black Sea,
crossed the Danube, harried without mercy the eastern empire and
collected tribute from Byzantium itself. Eastern Goths, Western

Goths, Vandals, Huns, Alans, Bulgars in turn punished the provinces
of Rome both east and west for having been prosperous enough to
produce material worthy of pillage.
The Bulgars remain as a name—their language has been absorbed
by that of the Slavs whom they conquered and ruled. The Alans melted
away as did the Scythians in the fat lands of Mesopotamia a thousand
years earlier, and as the Mongols did in China a thousand years later.
Many of the Huns of Attila’s empire merged with the conquered, but
one group went back to the grasslands of south Russia. Some 400
years later they returned to the plain of Hungary, where today they are
the only remaining citadel of their language.
THE ARABIAN GRASSLAND EXPLODES
The seventh and eighth centuries of the Christian era witnessed the
entry of the Arabian grasslands into the history of Eurasia in a large
way. It was not the first time that Arabia had played a part in the
history of lands beyond its border. One of the first recorded conquerors
of Mesopotamia was Sargon the Akkadian, 3800 B. C. Sargon was a
Semite, presumably from Arabia. Arabia is regarded as the original
Semite nest.
In Roman times succeeding generations of Arab horsemen harried
the Roman Empire. As the seventh century A. D. opened, Arabia was
a political chaos of independent oasis settlements and endlessly
quarreling nomad tribes.
A genius appeared upon the scene in the person of Mohammed, who
preached patriotism and religion. He used the sword to advance his
precepts and when he died in A. D. 632 Arabia was united.
The followers of Mohammed started a career of wider conquest. The
Arab horsemen and camelmen rode east, west, and north. In a few
years they had conquered Mesopotamia, Persia, Syria, Palestine, and
Egypt. In less than a century they had crossed the Ganges and the
Pyrenees, conquering all the lands between. Their defeat at Tours in
France in 732 by Charles Martel, who drove them back into Spain, is
one of the very important turning points of history.
THE MONGOLS AND THE TATARS
The eruption of the Arabs from their grassland was unrelated to
similar happenings in the greater grassland of the present Russian do-
main. The central grassland of Eurasia kept on producing horses and
men and marauding. In the ninth century a Russian chronicler re-
corded one of their many pillaging raids. “Whence they came,” he
lamented, “God. only knows, and whither they went, God only knows,
but while they were here they were terrible.”
378 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Unfortunately, later generations of eastern and southeastern Euro-
peans knew more than this about the Mongols and the Turks. ‘These
sons of the grassland came and remained to rule.
Genghis Kahn (Perfect Warrior), 1162-1227, son of a Mongol chief-
tain, was a supreme genius. He was probably the greatest cavalryman
that ever lived. In 30 years Genghis the Cavalryman spread his em-
pire eastward to the Yellow Sea and westward to the Adriatic and
the Baltic. Medieval Europe salved its sore vanity by saying that
Genghis overwhelmed by myriad numbers. Not so. He won by disci-

he defeated were usually much larger than his own, but he had more
men at the point of combat than had the enemy—“The mostest men

70,000 Europeans dead on the plain of Hungary, and then “reduced
three quarters of Hungary to ashes.”

been most carefully studied by Hitler and company in five different

strategy and surprise remains. Genghis seems to have been a true

for peoples called Turanian. The names Turki, Turcoman, or Turk
have been variously applied to a dozen or more ethnic groups living
west of the Great Wall and close kin to Mongol and Hun. The mo-
bility of these horsemen of so-called Turkish stock was so great that
in a short period they were to be found at Lake Baikal and also in
Morocco, 7,000 miles distant. When the Russians took Merv less than
100 years ago, the Turcomans of the nearby steppes were known by
their neighbors as “the man-stealing Turks.”
The Turkish group that conquered Constantinople has repeated
the southwest Asia historical cycle with variations. They came from
GRASSLAND AND FARMLAND—SMITH 381
Turkestan, crossed a corner of Persia, and settled in Asia Minor.
There they increased, organized, and crossed the Bosphorus. Pass-
ing the walls of Constantinople the invaders established themselves
in southeastern Europe in the early 1300’s. After generations of war
they took Constantinople in 1453 and extended their empire into
Hungary and south Russia. In 1683 the Turkish siege of Vienna was
raised by John Sobieski, of Poland.

If anyone is inclined to criticize the Balkan peoples for some cul-

escaped.
During much of this long era of Turkish rule there was something
like guerilla warfare here and there in the broken area we call the
Balkans. In such a time men think of chieftains, leaders, not such
abstractions as democracy. In 1943 and 1944 we heard much about
Mihailovitch and Tito—two.more chieftains.

The second route from the left is the Khyber Pass. No one knows the number
of bands of migrants, marauders, or organized armies that have marched
through that very favorable opening in the mountain wall. There were those
of Alexander, Tamerlane, and George V. Today it has a strategic railway,
and bristles with pillboxes perched high aloft on many commanding hills.
RUSSIA TAKES THE STEPPES
Gunpowder with muskets and cannon ended the career of the horse-
men of the steppes after an undisturbed independence of unknown
duration, and after about 4,000 years during which the horsemen over-
ran almost at will their more civilized neighbors on the east, south,
and west. In 1580 the Russians with muskets, cannon, and wagons
crossed the Urals. In 300 years they subjugated the whole of central
GRASSLAND AND FARMLAND—SMITEH 383
Asia and all its horsemen right down to the mountain walls of Persia,
Afghanistan, and the outer provinces of the old Chinese Empire.
The tables were turned. The mobile grassland horseman found
himself dominated by a machine-using sedentary man from beyond
the grassland border.
It is interesting to contemplate the almost unchanging continuity
of two culture types: East of the Great Wall, in the good farmland
of the Chinese plain, the man with the hoe, the mud village, the brick
temple. This man was, and is, a peace-loving creature untempted by
the lure of conquest, praying to be let alone in his garden. Instead
he has been the victim of oft-repeated pillage.
West of the Great Wall the grassland man, riding a horse, living in a
tent, menaced by perennial uncertainty of supplies of grass and water.
His temptation to maraud was strong and oft-repeated. The mobile
existence of the grassland man made it easy for him to raid and pillage.
The grain bags of the man with the hoe offered an easy objective.
Thus, for 4,000 years grassland culture changed but little and the raid-
ing nomad never ceased his attacks. Almost any year cavalry could
muster on the plains and in irresistible numbers appear unannounced
in the farmland beyond the mountain. Thus civilization after civil-
ization and empire after empire developed in the farmlands and fell
before the man from the grassland.
Grassland society permitted and encouraged military power, often
unlimited except by the whim and fancy of him who wielded it. Temp-
tation to yield to the power lust was more frequent in the grasslands
than in other environments. The power lust is unique among man’s
desires. The gratification of the desire for food, drink, sex, the pleas-
ures of the chase, of workmanship, of the intellect, of creative art—the
exercise of all these leads to satiety and sleep. But in terrible contrast,
the lust for power grows by gratification. It runs away with the
human spirit. At times it unbalances the mind. The Romans with
the pitiful record of emperors before them had a word for it—“Impe-
rial Madness.”
History furnishes overabundant illustrations. To read “Mein
Kampf” and contemplate the actions of the Nazis proves the present
and continuing menace of unchecked power. The dangerous thing is
that the power lust is born in all individuals. It is even shared by
some of the quadrupeds.
If the turbulent history of the Eurasian grassland has any message
for this generation of men it is an imperative command to so organize
our affairs that no race, nation, or group can get into a position of
unlimited power over other large groups.
Gunpowder and the railway reduced grassland man to impotence.
They made him the vassal of the man from outside whose machinery
could outrun the horse and outshoot the horseman’s bow or rifle.
384 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
But what about this Eurasian grassland as a stage and base of opera-
tions in the world of tooth and fang, but equipped also with plane and
bomb ?
Mackinder pointed out at the end of World War I that land-based
air power would soon make the Mediterranean untenable to any kind
of shipping. Here he showed himself a most true prophet. History
has vindicated Mackinder. It has also vindicated Woodrow Wilson’s
dictum that if any people or nation is not safe, no nation is safe.
Immensely strengthened is the argument for world organization to
outlaw war. If our intelligence is any greater than that of the sheep
or the cow we will strive for international organization that is
equipped for:
1. The removal of international tensions before they make
explosions.
2. The treatment of any war as we treat smallpox and rabies.

SOUTHERN ARABIA, A PROBLEM FOR THE FUTURE?
By CarLetron S. Coon
Harvard University
INTRODUCTION
The one corner of the Asiatic continent with which archeologists,
ethnologists, and physical anthropologists have concerned themselves
the least, for excellent reasons, is southern Arabia. This pardonable
neglect stands in inverse ratio to the region’s natural appeal and
interest. The whole Arabian peninsula, from one standpoint, forms
one of three vermiform appendices dangling from the main mass of
Asia into the Indian Ocean. Arabia, southern India with Ceylon,
and the Malay Peninsula, have all three served as culs-de-sac to old,
discarded, and forgotten fragments of humanity, pressed out of circu-
lation by the movements of more vigorous and more civilized groups
to the north. The parallel between southern Arabia and the other
two appendices is clear. The primitive Bedawin of the Hadhramaut,
who form the substratum of that country’s population, and the non-
Arabic-speaking natives of Mahra and Dhofar, serve as the western
counterparts of the Vedda, the Semang, and the Sakai.
But there is another facet to this comparison. Just as the brilliant
Sinhalese civilization flourished in Ceylon, just as the Mon-Khmer
civilization reached sculptural heights in the jungles of Cambodia
and Siam, and Hindu culture was carried over into Sumatra and Java,
so southern Arabia has at the same time played a second role, that of
a hothouse of high oriental civilization in antiquity. Here flourished
1The purpose of the author in writing this paper is to summarize the existing informa-
tion, available to him, concerning the prehistory, archeology, and ethnology of the por-
tions of Arabia lying south of the twentieth parallel, especially the kingdom of Yemen and
the regions of Hadhramaut and Dhofar, and the island of Socatra, and to interpret that data
both historically and ethnologically. In so doing the author has drawn heavily on several
sources: Maj. H. St. John Philby’s articles in the New York Times of September 12 and
19, 1937; Dr. Cesare Ansaldi’s book, “Il Yemen’; the sections written by Drs. Nielsen,
Hommel, and Rhodokanakis in the ‘Handbuch der altarabischen Altertumskunde”’; Van
den Berg’s “Le Hadhramout et les Colonies Arabes dans 1’Archipel Indien’; ‘Southern
Arabia,” by Theodore and Mrs. Bent; and “Arabia Felix,” by Bertram Thomas.
The bulk of the information comes from the aforementioned sources, most of the rest
from the author’s field notes. The interpretation, unless otherwise acknowledged in the
text, is original,

the famous kingdoms of the Sabaeans, Minaeans, Katabanians, and
Hadhramautis, whose splendors were immortalized by the biblical
account of Solomon and the Queen of Sheba. Under the encroaching
sands of the Empty Quarter lie the feet of splendid temples and lofty
skyscrapers, abandoned to the desert after the breaking of the Marib
dam, and the shift of the frankincense trade from the overland route
to the sea.
The peninsula of Arabia can hardly be called a unit. The Empty
Quarter, probably the world’s largest stretch of sheer and utter desert
without oasis and without relief, acts as the center of a ring, about
which are set the Arabian kingdoms, like jewels of different hue and
luster. The Empty Quarter divides these kingdoms as no sea could,
for one can sail across seas, and some, such as the Mediterranean,
and the Indian Ocean, have acted in history as highroads rather than
as barriers. There is no barrier so great as a complete desert. The
Empty Quarter may be crossed by camels and has been so crossed
over long periods of time; this has been proved by the personal ex-
perience and inquiries of Bertram Thomas. Such crossings, how-
ever, are extremely exceptional, and most of the inhabitants of Arabia
today entertain only fabulous notions of the actual character of this
extensive waste.
Although it would please exponents of pan-Arabian solidarity to
think that all the Arabs in the whole peninsula and elsewhere form a
racial and cultural unit, the truth is quite the opposite. Arabian
unity north and west of the Empty Quarter may well extend into Syria,
Iraq, and North Africa, but south of the great desert the vermiform
appendix plays its retentive role. Here, small, ringlet-haired men,
painted blue, swear mighty oaths over the tombs of Jnun, milk their
cattle, sleep in caves, and initiate their sons in mass ceremonies of an
Australoid character. ‘These men are not Arabs in the modern, Islamic
sense; they are the survivors of an earlier age.
Southern Arabia may be divided geographically into a number of
discrete units. Most important politically, and in reference to popu-
lation, is its westernmost segment, the divine kingdom of Yemen, where
approximately 3 million farmers water their terraces and reap their
barley under the spiritual sanction of their Imam. The Yemen con-
sists geographically of two main parts, separated by a formidable
barrier. The first part is the Tihama, a narrow coastal strip in which
sand dunes alternate with fields of sorghum, and occupied by a mixed
population of Negroid serfs from Africa and small elflike, brachy-
cephalic men, whose racial origin is still a mystery. The barrier is a
10,000-foot escarpment, rising sheer from the coastal plain, crowned
by a range of castellated peaks, and folded and eroded into countless
valleys.
SOUTHERN ARABIA—COON 387
This escarpment has been almost completely terraced by man. On it
erow crops of luscious fruits, various hard grains, and the entire supply
of the world’s finest grade of coffee. Beyond the escarpment stretches
a vast upland plateau, sloping gently eastward and drained into the
Wady Hadhramaut and the Indian Ocean. From the edge of the

escarpment to the ill-defined border of the gradually encroaching
Empty Quarter stretches a wide belt of terraced land on which great
crops of grain are grown by the Imam’s subjects. The desert border-
land, itself once the seat of garden states watered by means of huge
dams, is now occupied by a few scattered tribes of Bedawin, who make
388 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
their living by exploiting the natural salt deposits situated near the
great city-sites.
To the east of the Yemen, and to the south of the westernmost exten-
sion of the Empty Quarter, lies the famous region called Hadhramaut,
a country whose size diminishes as one approaches it. To the outsider,
the Hadhramaut comprises most of Arabia east of Aden, west of Mahra,
and south of the desert. To the Hadhramis themselves, it includes
only the narrow valley which bears its name, and the string of towns
built along it. The Hadhramaut, like the Yemen, is the seat of intense
agricultural activity, but in a much more restricted sense, since only the
river valley and the beds of its tributaries are actually productive,
while the nearly denuded mountain region lying between the valley
and the sea is used for camel pasture and the passage of caravans.
The sea coast of the Hadhramaut is a negligible geographical expres-
sion, since the cliffs which hem in this valley to the south arise almost
directly from the water.
East of the Hadhramaut lies what is, to most ethnologists, probably
the most interesting section of southern Arabia. ‘This is the half moon
of Dhofar, a small coastal plain hemmed from behind by the Qara
Mountains, against which the full force of the Indian monsoon unloads
seasonal rain in abundance. Dhofar alone retains the damp tropical
climate which, the geologists tell us, at one time characterized the
whole southern strip of Arabia. In Dhofar survive mangrove
swamps, miniature jungles of tropical palms, and on the slopes above
the plain, an abundance of those small, fleshy bushes from which are
bled the frankincense tears so greatly prized in the ancient world.
In the highlands behind Dhofar survive pre-Arabic Semitic lan-
guages; ? and a cattle culture comparable to that of the Toda of India
on the one hand and of the East African Hamites and Bantu on the
other, as well as certain customs and practices of a very primitive
character.
When we leave Dhofar we enter the domain of Oman proper, but
we are no longer in the strict sense concerned with southern Arabia.
The bulk of Oman is situated in a latitude north of Mekka, and even
with that of Medina. Except for the alleged Negrito strain in the
population of Cape Musandam, its relationships are primarily with
the valley of Mesopotamia and with the coast line of Iran. Southern
Arabia, in the strict sense of the word, cannot be said to extend
north of the twentieth parallel.
PREHISTORY
There can be little doubt that, during parts of the Pleistocene period,
southern Arabia enjoyed a much more felicitous climate than it does at
2 Thomas, 1937b.
SOUTHERN ARABIA—COON 389
present. The Empty Quarter, after all, is nothing but an eastward
extension of the Sahara, a part of the general belt of arid uplands
extending across vast expanses of Africa and Asia. Since the climatic
history of the Sahara is now partly known, it is possible to reason by
analogy with some hope of justification.
During the Pleistocene, a number of pluvial periods turned the
Sahara, at alternate intervals, into a great plain of grass and park-
lands, drained by huge rivers which carved its deep wadies, now water-
less and denuded, into sculptural masterpieces of erosion. In south-
ern Arabia, the size and volume of the dry river courses bear evidence
that the same process took place here as well, and that during these
periods of abundant rainfall the Empty Quarter itself formed a
grassy plain of lesser size, offering food and shelter to herds of rumi-
nant mammals, and to man.
After the last pluvial maximum, Arabia, like the Sahara, began to
dry out. The abandonment of Marib, the gradual disuse of the ter-
races along the Yemen escarpment, and the turning of the northern
Arabs to pastoral nomadism with dependence on the camel, may all
have been secondary manifestations of this increasing desiccation,
and we have no evidence that the drying-out process has yet come to
an end. Arabia today holds somewhat less than 6 million people.
Five thousand years ago, when agriculture was already old but lit-
erate civilization new, Arabia might presumably have held twice that
number. If we are to reconstruct the history of Arabia, however, we
must turn back still farther, and postulate a time in which the whole
southern border of the peninsula resembled the present Dhofar, and
in which the Empty Quarter and the regions north of it were grassy
plains.
At that time, it is possible that Arabia was a home of human beings
of ancestral European type, and advanced beyond their fellows in the
glacial north. It is too early, however, to present this hypothesis with
conviction, for at present Paleolithic archeology in Arabia may be
said hardly to have begun. In the Nejd, Doughty * found Paleolithic
implements, in the form of hand axes; Henry Field,‘ in a motor trip
across Transjordania and the desert border of Iraq, established the
presence of Paleolithic industries from the Acheulean stage upward,
while Philby,* in his recent trip along the southern border of the
Empty Quarter, has likewise discovered Paleolithic implements of
nature as yet unstated.
Miss Caton-Thompson,* however, has found paleoliths in situ in
the Hadhramaut; these are of Levalloisian type, and poorly executed.

They seem to have been used over a long period of time. So far, none
of the hand axes so typical of northern Arabia have been found south
of the Ruba’-el Khali, which was perhaps as much of a refuge area
in Paleolithic as in historic times. In other words, the geographical
forces which divide northern and southern Arabia into separate cul-
tural entities today may also have operated as far back in human his-
tory as Pleistocene times.
Southern Arabia may also hold the answer to some of the problems
concerned with the rise of the Neolithic economy in the Old World.

seem to be old centers of terraced agriculture. In Ethiopia, a number
of unique local species of cereals have been found. So far, the Yemen
has escaped the attention of economic botanists, but this region may be
of great interest in this connection. It is just possible that some
aspects of the Neolithic economy may have developed in this area.
Megaliths, too, are present in southern Arabia. In his recent jour-
ney through Asir and the desert borderland of Yemen, Philby’
noticed the presence of cromlechs similar to Stonehenge, made of
double concentric circles of huge slabs of granite, with central corri-
dors oriented to the east and west. He also found semicircular pas-
sageways, and vast fields of dolmenlike tombs both with and without
corridors. Further study on the spot will be needed to determine both
the age of these structures and their relationship, if any, with the
megalithic complex in the Mediterranean and western Europe. At
present, however, it would seem that they have a strong continuity,
at least in an architectural sense, with the historic cultures of southern
Arabia.
Aside from archeology, southern Arabia may contain the solution
of an important question in the racial field: “What role did the south-
ern coastal strip of the peninsula play in forming a connection be-
tween the frizzly-haired, deep-pigmented peoples of Africa and
Oceania?” In Africa the general Negroid family is represented by
true Negroes, Pygmies, and Bushmen. In southern Asia and Oceania,
from India to Fiji, one finds various kinds of Negritos, all occupying
marginal areas, as well as Melanesians and Tasmanians. There is
probably some genetic continuity between the Negroids of these two
major areas, and since the fringe of southern Arabia lies in between,
some traces of whatever group served as link might possibly be ex-
pected to survive. Such a survival does actually occur.
The population of southern Arabia, aside from the Yemen, consists
of two major elements—Mediterranean and Veddoid. In the Ha-
dhramaut Valley, the agriculturists are predominantly Mediterra-
nean; among the Bedawin, and among the wilder tribes of the Dhofar
7Philby, 1937.
SOUTHERN ARABIA—COON 391
region, the Veddoid element increases in importance. There is, how-
ever, a third element—frizzly-haired, short-statured, round-headed,
which occurs among sporadic individuals, and which is presumably
Negrito. Individuals possessing these traits are not to be confused
with African Negro hybrids, who are well recognized and who are
differentiated from the rest of the population in a social sense, nor
with Somalis. The tribesmen of Cape Musandam, in Oman, are said
to be predominantly Negrito.®
The tentative identification of a submerged Negrito strain in south-
ern Arabia, which can be confirmed only by further work on the spot,
leads one to suggest that the connecting link between the African and
Oceanic Negroids may be Negrito—the only type which both have in
common. It is very likely that the Negrito is an extremely ancient
human type, as witnessed by its marginal position, and that it antedates
in development both the African Negro and the Melanesian, which
latter is probably a hybrid. Southern Arabia was presumably at one
time merely a segment of the forested belt which the Negritos of the
world occupied, and in it the Negrito factor may well antedate the
Veddoid.
THE PRE-ISLAMIC KINGDOMS ®
When we approach the problem of the literate city-states of pre-
Islamic southern Arabia, we reach somewhat firmer, though still
shaky, ground. We know that there were four kingdoms, from north-
west to southeast: Ma‘an, Saba, Kataban, and Hadhramaut. Their
capitals were, in order, Ma‘an, Marib, Tamna, and Shabwa. Of these
four, Tamna has not even been located. Ma‘an and Marib were visited
by furtive epigraphers in disguise, in the 1880’s, and then left unknown
until 1935, when Hellfritz, under escort by the Imam’s soldiers, was
hurried through the latter. The same adventurer also passed through
Shabwa equally rapidly. In 1936-87, Philby spent a total of 8 days at
Shabwa and peered at Marib from a distant hill.
Under these circumstances, it is no wonder that our knowledge of
these kingdoms is scanty. It is largely derived from Greek accounts,
and from the translations of inscriptions—some copied in the cities
themselves, others photographed and copied in the Imam’s Museum
at Sana‘a, and still others brought out to the coast at Aden. Other
objects in the Imam’s Museum: hastily examined by the author and by
Dr. Schlobies, contribute further evidence. The Peabody Museum
of Harvard University and the Semitic Museum of the same institution
have small collections which await competent study.

Despite the paucity of information and the general lack of interest
in this most important field, linking as it does the civilizations of two
ancient worlds, the trade of the forger flourishes. The rare visitor to
Sana‘a is besieged by dealers in statuettes and inscribed stones, some
blatantly poor and new, others clever and difficult to detect. Silver
coins of the Sabaeans, however, are abundant, and a drug on the
numismatic market,
What do these objects so far found tell us? Their surface message
is clear. The kingdoms of southern Arabia, like that of the Nabatae-
ans farther north, were in contact with the entire ancient world, from
Rome to India and perhaps beyond. Objects of Roman, Greek,
Egyptian, Mesopotamian, and Indian manufacture abound. Scarabs,
amulets, bronze statues in the Roman manner, dragon-feet and grape-
bunch ornamentation in the Syrian and Byzantine manner, and Gre-
cian columns all witness the especial linkage of this region with the
Mediterranean. The names of gods monotonously repeated, the abun-
dance of seated votive idols and ex votos, from phalli to oxen, indicate
a devotion to religion and a belief in divine cures. Animal figurines
show humpless cattle of the long-horned variety, like those of Hotten-
tot and Galla, dromedaries, horses, ibexes, and gazelles.
Bronze is the common metal, iron rare; gold and silver are not scarce.
Microlithic flakes of ornamental greenish stone and of obsidian were
apparently used as cutting tools and as arrowheads, along with metal.
Palettes indicate the great use of mineral cosmetics, as in predynastic
Egypt. Statuettes and bas-reliefs show the skirt or breechclout to be
the common costume. The sculptural level in purely native art is
not high enough to give us an accurate idea of the racial types
present, except that the people were undoubtedly white, had prominent
noses, and that the men wore beards. There is no reason to suppose
that they were any different racially from the Mediterranean Yemeni
highlanders of today.
Without question a careful study of authentic South Arabian archeo-
logical specimens, even those removed from their contexts, as all
those available are, could do much to solve the problem of the contacts
and influences of this civilization. But such a study is yet to be made.
From the inscriptions, and from classical and Arabic documents, we
may build a second picture—that of the ethnography of these king-
doms; their boundaries in time and space, their social structures, their
religious practices, and their economic life. With the aid of the prodi-
gious scholarship of Nielsen and his associates, we will proceed to
discuss these in brief.
It cannot yet be determined with any accuracy when the South
Arabian kingdoms were first established. It is known, however, that
Ma‘an was probably the oldest, with Kataban perhaps nearly as old,
SOUTHERN ARABIA—COON 393
while the Sabaean kingdom was, relatively speaking, young. The
history of southern Arabia, as an important center of civilization,
may have started, however, as early as 1300 B. C. and it continued
until the time of Mohammed. A more conservative, but otherwise in
no way preferable, date is 900 B. C. Whichever or whatever date one
accepts, there can be no doubt that this cultural emergence was pre-
ceded by centuries of preliterate, in a sense predynastic, agricultural
civilization.
At some chronological point between the two dates mentioned,
southern Arabia came into prominence as a highly civilized agricul-
tural region, flourishing near the source of the incense trade route,
which went up from the Hadhramaut around the western edge of the
Empty Quarter to Mekka, Medina, and the ports of the eastern Medi-
terranean. It also served as the principal or only route by which goods
from India were transshipped and carried overland. This trade posi-
tion was highly artificial and depended almost wholly upon the sup-
pression of the sea route up the Red Sea. When this was opened, in
the second century A. D., the kingdoms of southern Arabia fell, and
the country lost its importance to the world.
Of the four kingdoms, Hadhramaut alone produced incense, which
also came from Dhofar farther east. The other three lay on the trade
route and served as carriers, thereby collecting their “cuts” from the
rich trade profits. A tear of incense resin, of negligible value on the
tree, had been doubled and redoubled many times in price before it
reached the Mediterranean. This ancient racketeering was based upon
two sound economic principles, as valid now as then: the first, that
of the monopoly, and the second, that of bought protection, in which
the Arabs and desert people elsewhere have long been experts.
The Minaean kingdom, which was apparently the oldest, had passed
its period of efflorescence before the Sabaeans began. It was also
the northernmost, located in the Jauf and Nejran, with Ma‘an its main
city. Nielsen believes that the basic elements of this civilization came
from the coastal strip along the northern Persian Gulf, which the
Arabs call Bahrain, and the Babylonians called Magan. According
to Nielsen, Ma‘an=Magan, with the ‘ain substituted for the Baby-
lonian G. 3
There were 20 Minaean kings, covering, in their combined reigns,
a period of at least 600 years. The older estimate would place the
Minaean period from 1300 to 700 B. C.; the younger, from 900 to 300.
If the alphabetic inscriptions from Ma‘an go back to the oldest period,
then the younger dating is the more likely, since, in the Sinai region
and northern Arabia, alphabetic writing does not antedate the first
millennium. The age of the Katabanians is also in doubt, but in all
probability their kingdom was roughly contemporaneous with that of
394. ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
the Minaeans. At what time Hadhramaut changed from a trade depot
to a kingdom is not known.
The Sabaeans appear toward the end of the Minaean reign, perhaps,
as Nielsen suggests, from the northern Arabian Jauf. They were
perhaps also camel nomads, who carried the trade for the Minaeans,
and who, later having decided to take their share of the business di-
rectly, established a domain in the south, grafting themselves on the
northern portion of what had been Katabanian territory. There are
‘two Sabaean periods: the earlier, called the Mukarrib period, in which
the king bore the title mukarrib, which indicated a primarily priestly
office, and a later, in which he is called malik, the common Semitic
word for king. A parallel transition took place in Kataban. The
exact dates of these two periods are unknown, depending on a floating
correlation. For the first Nielsen offers 1115-815 B. C., 950-650 B. C.,
and 815-510 B. C., of which he prefers the middle one. This, of course,
goes with the early dating for the Minaeans.
The most important Mukarrib of Saba was Karika-Ilu (the Priest
of the God Il), who killed 4,000 men in a war against Kataban, then
turned on Ma‘an and killed 45,000 while taking 63,000 prisoners and
31,000 head of cattle. At the same time his army laid the Nejran
country waste, destroying the Minaeans forever. Two Assyrian in-
scriptions, dated 715 and 685 B. C., respectively, serve to locate this
Kariba-Ilu accurately in time. He gave presents to King Sargon of
Assyria, although he was in no sense a vassal of the latter monarch.
The difficulty in pinning the entire chronology to him is that there
were several kings named Kariba-Ilu, and it is not yet known which
one of them was the great conqueror and Sargon’s friend.
At any rate, this Mukarrib period was the period of rise and efllores-
cence for the Sabaeans. They established themselves definitely as
the principal people in southern Arabia; for after destroying the
Minaeans and crippling the Katabanians and Hadhramautis, they
turned to offer these two latter peace and alliance, which must have
implied a Sabaean hegemony. The material high point of this period
was the erection of the great dam at Marib, which provided irrigation
water for the whole section.
From about 650 to 115 B. C., according to Nielsen’s correlation, the
Sabaeans continued to be the dominant people in the incense and In-
dian trades. This was the Malik period. In 115 B. C. their nation be-
came the dual kingdom of Saba and Dhu Raidan, with rival families
arising ; the Hamdanis, of whom there is still an entire tribe in Yemen,
and the Himyarites, who were only a single noble family, although
their name has erroneously been preserved as the title of the whole
South Arabian civilization. The Hamdanis were centered at Marib,
the Himyarites at Dhu Raidan. From 115 B. C. to A. D. 270 these
SOUTHERN ARABIA—COON 395
two families jockeyed each other about in their struggle for exclusive
power.
The later history of southern Arabia, until the arrival of Islam, is
relatively well known. In 24 B. C. Aelius Gallus led an expedition
to conquer this whole section, known to the Romans as Arabia Felix,
but the Romans never got there. Somewhere in the sands near the
Nejran the majority of them perished, and those who survived at
this point turned back. About A. D. 270 the Axumite Ethiopians
conquered Arabia Felix and ruled it—they were Christians and set up
bishops and bishoprics. But by A. D. 378, apparently, their rule
had come to an end. The Axumites themselves were the descendants,
in whole or in part, of earlier emigrants from the Hadhramaut, who
had carried Semitic civilization to Ethiopia and there become
Christianized.
In A. D. 449 and 450 the dam at Marib burst twice, washing out the
valley and ruining agriculture, and at this time there must have been
a mass exodus. Perhaps it was at this time that the region of Sana‘a
became the nucleus of Yemen. The later kings, who ruled before the
bursting of the dam, were in many instances Jewish in religion, and
the strong Jewish colony of Yemen had before then been founded.
In A. D. 525 the Ethiopians returned, and in A. D. 570, the birth year
of Mohammed, the Ethiopian viceroy Abraha, who ruled Yemen,
organized an expedition, mounted on elephants, against Mekka. This
expedition soon came to grief, however, and in the same year the
Persians conquered the country. In A. D. 628 the last Persian gov-
ernor became a Moslem, and Arabia Felix was ruled from Mekka. By
the time of the establishment of Islam in Yemen, southern Arabia had
lost its earlier importance. This was due to the break-up of the over-
land trade, caused chiefly by the establishment of ports along the
coastal Tihama by the Ethiopians. Before this time we hear little of
the coastal plain—it was ethnically a different country, as it is today.
About the political and social organization of the four southern
Arabian states, we have sufficient information to permit the recon-
struction of at least a plausible if striking system. Since each of the
four was organized in essentially the same way, it will suffice to de-
scribe the functioning of the best known, Saba. Here society was
graded and subdivided on two interlocking bases, kinship and in-
heritable rank. These divisions were formally expressed by the pres-
ence within the state of several parallel tribes and four graded classes.
The tribe was both a kinship grouping and a geographical expression;
each tribe except one was a completely parallel unit, which included
members of the three lower classes, in approximately equivalent pro-
portions. The one asymmetrical tribe possessed in addition the entire
personnel of the highest class, small in number, and including the
priest-king and his near kinsmen.
396 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
The state was named after the leading tribe, and the capital was
situated in this tribe’s territory. The king was the representative of
godhead on earth, the chief diety which he represented was the na-
tional god of the state, although each tribe kept its own tribal divinity
as well. The leading tribe was concerned with the maintenance of the
main temple and of shrines; thus, the leading tribe maintained its
political ascendancy through a religious sanction.
Each tribe was bound to a certain section of land and was responsible
for the agricultural success of this allotment. The members of the
tribe were obliged to remain on this land and could not farm else-
where—there was no freedom of movement from the agricultural and
residential standpoint. For political purposes, the tribe was sub-
divided laterally into thirds or quarters, and tribes could be recom-
bined arbitrarily for political purposes. In this way the genealogical
solidarity of the tribe could be broken down and must eventually have
become secondary to the geographical tie. This organization into
tribes and subtribes made it easy for the government to levy armies
and collect taxes, and also to provide for the poor.
Local landholders, belonging to the upper tribal class, were also war
leaders and were responsible for the raising of covées to execute public
works, particularly irrigation projects, and to maintain the highway
along which the precious frankincense traveled. Furthermore, these
tribal leaders were charged with recruiting warriors and overseeing
agriculture; for if any lands were neglected or poorly farmed, the
tribal overlords were held responsible.
The three social classes, aside from the divine upper crust, are desig-
nated by the as yet vowel-less words Mswd, Ksdn,and Dmwt. For the
sake of simplicity, we shall designate these by the numbers 2, 3, and 4,
leaving number 1 for the royal caste. Number 2 was a privileged class
of landowners, with the feudal rights mentioned earlier; number 3
formed the most numerous group, consisting of free landholders, the
owners of small, individual properties, who provided the bulk of the
working power. They were farmers, paid a land tax, did military
service, and submitted themselves to the feudal authority of the noble
families of the second class. Members of class number 3 were further
subgraded into categories by occupation, since they apparently in-
cluded in their numbers the skillful artisans responsible for the high
level of South Arabian material culture. If the modern parallel in
Yemenite society reflects an earlier condition, then the farmers proper
must have been superior socially to the artisans. The members of
class number 4 were landless serfs, without political freedom. It is not
known whether or not they fitted into the genealogical scheme upon
which the tribal structure was erected.

SOUTHERN ARABIA—COON 397
An officer called Kebirv, in Greek rpecBirepos, presided over each
tribe as head. The name itself implies that he was originally an elder,
and that his position was determined by family precedence. His office
was partly priestly, perhaps in the earlier stages of South Arabian
social evolution largely so. It was he who brought sacrifices to the
tribal temple and offered them to the tribal god.
Besides the lands governed by the tribal princes, there were crown
lands governed directly by the king, and the occupants of these terri-
tories paid him taxes and military services. Presumably these were the
lands occupied by members of his own tribe. Much of the land also
belonged to the temple; on it were priestly colleges, each with its Kebir.
Thus, the prototype of the modern zawya and its sheikh or fakih
existed in pre-Islamic Saba. Every member of society, of whatever
class, was obliged to do some work on the temple lands, and the gods
were offered sacrifices, ex votos, and the tithes of all produce. The
temples themselves were built with money given or bequeathed as
offerings to wipe away specific sins committed by the donors.
The dual system of national partitionment, vertically into tribes and
horizontally into classes, produced a state held together by religious
sanction and by a specialized common economic purpose. Exactly how
the caravans were organized, and who had control of the road taxes,
we do not yet know, but the technique must have fitted into the system
already described.
One can find a number of parallels to this tightly integrated and
overtly stratified form of organization, in various parts of the world.
The Inca system in Peru was basically similar, and that of the Aztecs
was, at the time of Cortez, assuming a similar form, while the germs of
such a system may be found in the tribal organization of the Muskho-
gean peoples of the southeastern United States. In the Old World,
the Sumerian and Bablyonian systems were not radically dissimilar.
In Egypt the divinity of the king and the role of the nomes and
nomarchs might be considered parallel. The caste system, with occupa-
tional segregation, has its parallels in India, and may there go back to
the time of the Indus Valley civilizations. Thus the technical perfec-
tion of the South Arabian state, as exemplified by Saba, is not surpris-
ing, and its form relates it to the whole string of civilized communities
reaching from the Nile to the Indus.
But like all other systems, no matter how perfectly adjusted, it was
susceptible to change. As the Sabaean power grew through military
conquest, the importance of the military element naturally increased.
A subcaste, called by the consonantal sequence ’Khms, arose from the
middle class, to parallel the Kshatrias in India; this was a strong mili-
tary caste, which came in later periods to cut across tribal lines, and
developed into a strongly unified group which wielded great political
398 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
power. Its rise was perhaps comparable to that of the Nazi party in
modern Germany, whose beginning was both middle class and tinged
with military concepts. Needless to say, the rise of this fascist military
_class was entirely a Sabaean phenomenon; the power and initiative of
Minaeans and Katabanians had declined long before its inception, and
we know too little about the kingdom of Hadhramaut to make com-
parisons in that quarter.
The Katabanians, as a matter of fact, were more democratically gov-
erned than the Sabaeans, for each tribe had a council or assembly of
landowners; this was distinct from the parallel council of noblemen ;
thus, the Katabanians had a bicameral parliamentary government,
with a House of Lords and a House of Commons, with the king in the
supreme position, over both. This system may well have been the
early political formula of all of the South Arabian states, lasting
- through the Mukarrib period in Saba, and replaced during the Malik
period by the feudal system above outlined, eventually to be thrust in
turn into the shade by the rise of the military caste, and of the rival
warring families of Himyar and Hamdan.
The religion of these southern Arabian states, so intimately en-
twined with the social and political structure, is not easy to recon-
struct. Moslems are notoriously loath to preserve traditions of
earlier paganism and like to garble what pre-Islamic history they
permit to survive in anachronistic terms. Our religious sources,
then, are confined to the body of inscriptions so far published, and a
few superficial Greek observations. Although to competent Arabic
scholars the reading of the southern Semitic inscriptions is not diffi-
cult, since the alphabet may be learned in a few hours, and the gram-
mar and vocabulary are basically the same, the knowledge of this
writing passed out of common circulation soon after the Islamic
penetration brought a new Semitic speech and a new alphabet. In
the tenth century Abu Mohammed el Hamdani could still read the
old inscriptions, so we know that the knowledge had not, in his time,
completely died. He wrote 10 books about the olden times, of which
only 2 survive.
The inscriptions consist largely of the names of gods, of which
over a hundred are known. Many of them are attribute names, such
as Wadd, love; Sadik, truth; and Rahman, the Compassionate, which
passed over into Islamic terminology. Besides these are a number of
animal names: the bull, the horse, the ibex, the snake. Others are
kinship terms: father, paternal uncle, brother, mother, etc. Still
others symbolize the omnipotence of the god: Ba’al, the ruler; and
Malik, the king. Personal names of individual men are often of the
“Slave of the Compassionate” type, the pre-Islamic prototype of
‘Abd er-Rahman, and similar dedicatory terms. There is again a
SOUTHERN ARABIA—COON 399
class of god names which indicate tribal affiliation, the protector of
such and such a tribe, or paternal uncle of such and such a tribe.
Needless to say, this multiplication of god names does not imply
an extensive polytheism. All the names, all the gods, have been
reduced to three: the Sun, the Moon, and the Venus Star. These are
respectively represented in sculpture as a disk, a crescent, and an eight-
pointed star. Each of these three had many functions and attributes,
each with a name, and the reduction of these to three is only exceeded
by the Islamic heaping of all attribute names on a single divinity.
Although there were but three gods, each might be worshiped sepa-
rately in different aspects and under different names; thus the tribes
were still able to possess personal divinities. The state god of the
Minaeans was Wadd, that of the Katabanians ‘Amm, that of the Ha-
dhramis Sin, and of the Sabaeans J? Mukah. All were the moon.
There were no carved images of these three—the Semitic tabu
against graven images, while by no means generally applicable, was
in force in regard to the divinities themselves. What images we
find are of people. These gods, however, had perches or resting
places, in the form of crude stones, such as the Ka’aba itself. The
sun was a woman, and the moon her husband. Once a month, at the
time of conjunction, they had sexual intercourse; the stars are their
children, and of these Venus is the most important. These stars
eventually became angels; people and animals are also the children of
the gods. Thus, a direct kinship connection exists between this di-
vine trinity and mankind, with the head of the state acting as the
symbol and concentration point of godhead in man.
Among the northern Semites the sun was the most important, as
the promoter of fertility in vegetation; in southern Arabia, where the
sun is too hot for comfort, and scorches and withers, the night is the
time of coolness, and, in the moonlight, the time for travel and work.
Nomads travel much at night, and the moon with its phases gives
them their yardstick for measuring time. Thus, whereas the sun was
the important god to the northern Semites, the moon was supreme
among the southern groups, including not only the southern Arabian
peoples, but also the pre-Islamic Arabs proper, who lived farther north
in the peninsula.
The god J7 or JJah was originally a phase of the Moon God, but early
in Arabian history the name became a general term for god, and it was
this name that the Hebrews used prominently in their personal names,
such as Emanu-el, Isra-el, etc., rather than the Ba’al of the northern
Semites proper, which was the sun. Similarly, under Mohammed’s
tutelage, the relatively anonymous J/7ah became Al-Jlah, The God, or
Allah, the Supreme Being.
400 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
We know comparatively little about the technique of sacrifice em-
ployed in worshiping these divinities. The temple was the great
economic nucleus of each tribal region, with sovereignty over its own
grounds and fields, and it was ruled by its head priest with his troop
of acolytes. To it came worshipers bearing votive offerings, little
statuettes of gold in the forms of animals and men, brought to the
god as instruments of supplication for future favors and as rewards
for intervention in response to a previous oath. Models of arms and
legs represent the divine curing of these limbs. A Greek source of
the fifth century A. D. states that the Himyarites sacrificed the choicest
of their war booty in the early morning light, to Venus in his role of
Morning Star. The most important sacrificial victims were the hand-
some young boys who had been led to the temples as prisoners. The
same source also informs us that other tribes worshiped Venus in the
role of the Evening Star, an old man, and consequently rendered him
old men in sacrifice.
It is possible, as Nielsen has done, to fit this whole religious system,
as we now know it on the basis of incomplete evidence, into the general
Semitic scheme, in which the four kingdoms of southern Arabia, and
the northern Arabs as well, become the southern branch, and the Phoe-
nicians, Babylonians, Assyrians, etc., the northern, with the Jews
playing a mixed role. Whatever the findings of the learned school
of southern Semitists in Denmark and Germany, we must, as these
scholars would agree, still await excavation and a thorough strati-
graphic and typological study of remains on the spot before any of
the problems, religious or otherwise, which concern this civilization
may be finally settled.
For the present purposes it must be considered sufficient to have
presented the foregoing brief and unscholarly resumé of the work of
Nielsen and his associates, as a summary of present knowledge of this
intensely interesting and important archeological problem. But even
the short newspaper account of Philby’s journey, and Hellfritz’s uncrit-
ical hegira, as well as the observations made from the air by the French
aviators who, in 1935, flew over some as yet unidentified city, furnish
their contributions, as does the equally uncritical inspection of the
Imam’s Museum made by the author.
We know now that the influence of the late classical world on the
Sabaean kingdom cannot be overemphasized. Greeks or Byzantines
must have been imported to the Sabaean state to make statues and
carve stone. In earlier periods, Egyptian and Mesopotamian influ-
ences were equally important. The South Arabian cities were com-
mercial metropoles of a cosmopolitan character, grafted on a simpler
agricultural state, in which imported goods and styles probably were
more important than those which were more nearly indigenous.
SOUTHERN ARABIA—COON 401
This cosmopolitan character is revealed by the nature of the objects
found in Sabaean sites, many of which are too large to have been
imported and must have been made by traveling workmen. Other
things revealed by recent findings are Philby’s discovery that Shabwa
itself, although flanked by residential suburbs, was a small, walled-
city nucleus, scarcely 300 to 350 yards square, in contradiction to Pliny’s
statement that the city alone contained 60 temples. We now know
for the first time that the salt deposits at Shabwa, which are still
worked, formed a major incentive for the location of the city at that
spot, and that prosaic salt shared the trade with the more romantic
frankincense and myrrh. We also know that Marib is surrounded by
submerged volcanic craters, which, Philby suggests, may have erupted
at about the time of the destruction of Pompeii, thus weakening or
breaking the famous dam. Through the diligence of this same
explorer, we are introduced to a new city site, Ukhdud, in the Wady
Nejran, a step farther north from the Minaean center, and the seat of
a bishopric in Christian times.
Much remains to bedone. The field of southern Arabian archeology
is about to open. Let us hope that its miraculous preservation past
the period of trial and error in archeology elsewhere may permit slow
and careful excavation by properly qualified persons, trained in ade-
quate techniques. Let us further hope that the princes and kings who
control these sites will continue to be well advised and will refuse
permits to the sensational and the incompetent, following the policy
so ably expressed by His Excellency Raghib Bey, Foreign Minister of

THE NEW WORLD PALEO-INDIAN?
By FRANK H. H. Roberts, Jr.
Bureau of American Ethnology
[With 12 plates]
Scattered finds in North, Middle, and South America over a period
of years have added materially to the growing body of evidence for an
occupation of the Western Hemisphere in reasonably ancient times by
peoples who, judging from their physical characteristics, migrated
from northeastern Asia and became the basic aboriginal population
of the New World. In comparison with the remains of later periods,
traces of the early Indian are far from numerous. They are sufficient,
however, to demonstrate that more than chance occurrences are in-
volved and to justify the belief that further investigations will increase
knowledge about this phase of the pre-Columbian history of the
Americas. To name and describe all the discoveries pertaining to this
subject (Sellards, 1940) is beyond the scope of the present paper. It is
possible to discuss only a few of the recent and more important finds
and to consider their bearing on the problems of age and general
cultural status.
NORTH AMERICA
Beginning in 1926 and continuing through subsequent years a series
of discoveries in North America yielded evidence, now generally ac-
cepted, for a comparatively early occupancy. These finds consisted of
associations between stone artifacts and the bones from extinct species
of animals, of stone implements and hearths occurring in strata of
identifiable geologic age, of camp sites located along old terraces and on
the shores of lakes long since dry, and of human bones incorporated in
deposits of geologic significance. The materials from several of these
occurrences seem to be components of complexes from the same or
related cultural groups. In other cases the collections are from single
sites which appear, in the light of present information, to have no con-
nection with those found elsewhere. The evidence derived from com-
parable artifacts occurring under similar conditions at different loca-

tions is more convincing, of course, than that coming from only one.
A number of the thus far unique discoveries, however, have contributed
valuable information.
The most widely distributed and probably the best known is the
Folsom Complex (Howard, 1935; Roberts, 1935, 1939). The original
find in this category was made near, and took its name from, the little
town of Folsom in northeastern New Mexico. The Folsom Complex
consists of a variety of stone and bone artifacts occurring in deposits
indicative of some antiquity and in association with bones from extinct
species of animals or from forms not now living in the regions where
the finds are made. Three types of implements, the projectile points
and two kinds of stone knives, are characteristic and may be considered
criteria for the complex. The additional varieties of stone tools gen-
erally found accompanying those three types also occur in other com-
plexes and for the most part are too ubiquitous both in time and space
to have significance. The points and one type of knife (pl. 1) are
characterized by facial fluting. There are longitudinal channels on
each face, extending from the base toward the tip, which produce
lateral ridges paralleling the edges of the blade. The second type of
knife, made from the flakes removed when the other forms were fluted,
is a long, thin, plano-convex blade with approximately parallel sides.
The knives and one series of the fluted points were given a fine, second-
ary chipping along the edges after the channel flakes were struck off
the faces of the blade.
Other points, although fluted, tend to be more generalized in
character (pl. 2). They do not show as careful workmanship, do
not have the peripheral retouch, and are larger. The relationship
between the two forms and the reasons for their differences have not
yet been determined. Various explanations have been suggested.
One is that the larger forms represent an early development of the
type. Another takes the view that they may be a degenerate and later
survival of the better-chipped form. Still different is the idea that
they were used in killing large animals. Also, there is the possibility
that they indicate a borrowed technique in the method employed in
the manufacture of points, a technique that was never fully mastered
by those who took it over. Any one or all of these postulations might
apply in greater or less degree under varying circumstances. Definite
statements, however, are not warranted without specific proof. The
purpose of the fluting can only be surmised. It would facilitate
hafting, make for easier penetration, would probably stimulate
bleeding in a wound, and would tend to promote an inward working
of the point if it was broken from its shaft. The makers may have
had these or some other end in mind. That it was functional rather
than notional seems likely because the fluting weakened the point

and made it more liable to breakage, hence would not have been done
without good reason.
Animal bones with which Folsom implements frequently are asso-
ciated are those from bison, the mammoth, large American camel,
antelope, extinct and living forms of the musk ox, giant sloth, and
the native horse. The mammoth, sloth, camel, horse, antelope, and
kinds of bison represented are no longer in North America, and the
living type of musk ox is now far north of the area where the archeo-
logical specimens are found. Bones from animals still present in
various parts of the country also occur in Folsom sites. In this group
are rabbit, fox, wolf, deer, and pronghorn, species that have changed
so little over a long period of time that they have no bearing on the
problem of relative age. Some of the sites also contain invertebrate
fossils as well as mammal remains. Included in this material are
species that either are extinct or no longer live in the districts where
such assemblages occur. Wood, in the form of charcoal, found in
hearths and accompanying the bones has a similar status. There is
good indication of a climatic change and the lapse of an appreciable
length of time in these mammal, invertebrate, and charcoal remains
from species normally found in a colder and moister environment
than that prevailing today.
Good geologic evidence to augment that from the fauna and flora
was obtained from the excavations in three main Folsom sites. The
animal bones and artifacts at the original location in the northeastern
corner of New Mexico (pl. 3) came from a stratum of dark clay con-
taining gravel lenses and small concretions of lime, a deposit left by
an old bog or water hole. Extending several feet above this layer
were sediments consisting of highly restratified earth that have been
identified by some geologists as belonging to the close of the Pleisto-
cene or last ice age and by others as representing early Recent. All
agree, however, that their age closely approximates the transition
between the end of the Pleistocene and the beginning of the Recent.
In the Black Water Draw between the towns of Clovis and Portales,
180 miles south of the Folsom site in eastern New Mexico, the as-
semblage of bones and cultural material is found in a bluish-gray
deposit that is believed to be the bottom of old lake beds that cor-
relate with the high-water stage of ancient Lake Estancia located
some distance farther west (Howard, 1935; Antevs, 19352). Gen-
eral opinion is that Lake Estancia was at its maximum during a plu-
vial period when there was much heavier precipitation and tempera-
tures were lower, an era corresponding to the final stage of the Pleis-
tocene, and the bones and implements are regarded as dating from
that time. At the third site, the Lindenmeier, north of Fort Collins
in northern Colorado, the situation is somewhat different. At that
406 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
location the remains occur in the deposits of a vestigial valley bottom
that has taken on the appearance of a terrace as a result of the eroding
of the ridges that once bordered its southern side (pl. 4, fig. 1).
By correlating the occupation level, which is in the bottom of, or
just below, a dark-soil zone that was formed during a wet cycle
(pl. 4, fig. 2), with the terraces of the main drainage streams, and
those, in turn, with traces of glacial stages in the mountains on the
west, it was demonstrated that the period of the archeological re-
mains was near the close of the Pleistocene (Bryan and Ray, 1940).
Approximately the same geologic horizon is indicated in all three
cases and this is corroborated by evidence from several smaller sites.
As a consequence the belief that the Folsom Complex developed
toward the end of the Pleistocene or late glacial period and carried
over into the beginning of the Recent is now more or less generally
accepted.
A majority of the Folsom remains and sporadic traces of the com-
plex are found in the eastern part of the continent. Some have been
reported from the Great Basin—the plateau area comprising western
Utah, most of the State of Nevada, and southeastern California—
lying between the Wasatch Mountains and the Sierra Nevadas, and a
few points have been found in northern California where there is
one possible small site. Most of the material, however, is in the area
extending from Alberta and Saskatchewan in Canada on the north
to southern New Mexico in the south, from the eastern slopes of the
Rocky Mountains on the west to an eastern border that follows
roughly the western boundary of the Dakotas, cuts across western
Nebraska, Kansas, Oklahoma, and thence into Texas, where it turns
eastward to the Mississippi River. There are indications of smaller
centers in the region around the junctures of the Missouri and Ohio
Rivers with the Mississippi, in Ohio, western New York, western
Pennsylvania, Virginia, Tennessee, Georgia, and northern North
Carolina. An old medicine man in Sonora, Mexico, is reported to
carry two such points in his bag of fetishes. ‘There is no informa-
tion, however, on how he obtained them or where they were found, and
they have no value as evidence. The distribution of Folsom imple-
ments implies that there must have been some specific relationship
between the physical environment, the hunting economy basis of the
cultural pattern, and the period when the spread took place. The
latter will be considered in subsequent discussion, as it also has a bear-
ing on some of the other types of remains.
Papers pertaining to the general subject of the Paleo-Indian fre-
quently link another group of points with the Folsom series (pl. 5,
fig. 1). They are called Yuma from the county in eastern Colorado
where the first examples were found. The two forms were at first
NEW WORLD PALEO-INDIAN—ROBERTS 407
believed to be related because they were observed lying together
where the clay substratum had been exposed by the blowing away of
the surface soils. One typological study based on this material de-
rived the Folsom type from the Yuma, while another concluded that
the Yuma was an outgrowth of the Folsom. As a consequence the
terms Folsom-Yuma and Yuma-Folsom were used for a time. They
have been dropped by most writers, however, because subsequent in-
vestigations have shown that the two types are from different com-
plexes. The early forms of the Yuma may have been contemporary
with late Folsom types, but their main development was in subse-
quent periods. Asa matter of fact they continued to be made in some
regions until almost historic times. Because of this it is obvious that
Yuma-type points are not as significant as was previously supposed,
and their presence in a collection may mean little from the standpoint
of age.
Sandia Cave (pl. 6), located in the Sandia Mountains northeast of
Albuquerque, N. Mex., has contributed further evidence on the Folsom
Complex and in addition contained materials that put it in the cate-
gory of an individual or unique type of site. Three different assem-
blages of bones and artifacts were found in distinct levels in the
cave (Hibben, 1941). One includes cultural objects that are probably
pre-Columbian in age, yet are comparatively recent in origin. The
second series consists of specimens from the Folsom Complex, and the
third group is composed of artifacts that have been called the Sandia.
The top stratum or upper floor level contained the recent specimens.
This layer of dust, bat guano, pack-rat dung, and trash rested on a
hard crust of calcium carbonate that entirely covered and sealed in
the underlying deposits. Beneath this “floor” was a layer of cave
breccia containing the Folsom artifacts and bones from bison, mam-
moth, giant sloth, camel, native horse, and wolf. Below the breccia
was a stratum of yellow ocher in which were neither bones nor arti-
facts. Underlying the ocher was another deposit of cave breccia
similar to that above. The Sandia type implements and bones from
bison, camel, mammoth, mastodon, and horse came from this layer.
On the original floor were hearths. One of them was outlined with
small, rounded stones that must have been carried from the canyon
below because they were the only stones of that type found in the cave.
Charcoal, ashes, and fragments of burned bones filled the hearths, and
alongside the stone-encircled one was a Sandia point.
Typical Sandia points, the most characteristic artifact in the com-
plex, are readily recognized because they have a notch at the base on
one side only (pl. 5, fig. 2). There are two main forms with grada-
tions between that in some cases are difficult to assign to either cate-
gory because of their intermediate nature, but all have the basal
619830—45——27
408 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
notch. Sandia type 1 is lanceolate or rounded in general outline,
has a convex base, and is lenticular in cross section. Sandia type 2
tends to be more elongated with parallel sides, straight or slightly
concave bases, an occasional basal thinning produced by the removal
of a short flake suggestive of an incipient Folsom fluting, and a dia-
mond-shaped cross section. Single-notched points of the Sandia
types are not common in North America and only rarely are observed
in collections, principally in those from the southern plains area.
An example of Sandia type 2 was found early in 1944 weathering
out of a grayel layer near Abilene, Tex.,? in a district where there are
deeply buried sites that have yielded artifacts comprising another
complex that is regarded as being fairly old. The latter will be con-
sidered in some detail in subsequent paragraphs and need not be dis-
cussed further at this place. The Sandia forms are suggestive of the
well-known points from the Solutrean industry in the Old World—
in fact both types have analogs there—but probably were not derived
from, or related to, them. Besides points, the Sandia Complex in-
cludes stone kiiives, scrapers, pieces of large blades, and a number of
grooved stone balls. The knives and scrapers differ little from com-
parable implements found in the cultural materials of other hunting
peoples, but the stone balls are particularly interesting because they
suggest the bolas of South America. The latter, attached to the ends
of a thong or cord, are hurled at animals for the purpose of entangling
and catching them. If used for a similar purpose by the inhabitants
of Sandia Cave, they indicate a new trait in North America, one that
apparently was short-lived and very restricted in its distribution.
Where there is no direct physical connection between the deposits
in a cave and those of known geologic age in the surrounding terrain,
it is difficult to make correlations, and conclusions regarding their
relationship may be questioned. Indications are that the breccia of
the Folsom and Sandia layers and the intervening yellow ocher must
have been formed when there was much more moisture in the region
than has been known in recent times. The fauna, represented by the
bones, is characteristic of a cooler climate. Since cool, moist condi-
tions prevailed throughout this area in the pluvial period following
the maximum of the Wisconsin glaciation and the combination has
not occurred in sufficient degree to produce comparable phenomena in
the intervening millennia, it seems probable that the cave was occupied
at that time. Evidence from the Folsom sites, as previously men-
tioned, is for a late or terminal Pleistocene horizon, and it is logical
to suppose that the Folsom material in Sandia Cave would be of simi-
lar age. The Sandia artifacts, underlying the Folsom as they did,
would be somewhat older yet belong to the same general period.

Gypsum Cave (pl. 7, fig. 1), in the Frenchman Mountains east of
Las Vegas, Nev., also contained material of significance (Harrington,
1983). Several cultural horizons were represented in its deposits.
In the top layer were materials attributed to the modern Paiute In-
dians. Below it were two levels in which were articles left by groups
related to the Pueblo peoples of pre-Columbian times. These strata
rested on a sterile layer indicative of a break in the occupation of the
cave. In the deposits beneath the sterile bed were archeological spec-
imens, quantities of sloth dung, bones from the giant sloth, an extinct
species of wolf, three species of camels, and the native horse. The
evidence appeared to demonstrate contemporaneity between the
makers of the artifacts and all the animals except the horse. Al-
though there was some doubt about the latter, those making the
investigations expressed belief that the animal still survived in the
region when the cave was occupied by men and that they were more
or less acquainted with it even though they apparently did not hunt it.
This opinion was predicated on the fact that projectile points similar
to those obtained from the cave, long triangular-shaped blades with
square shoulders merging into a stem that tapers into a rounded or
pointed base (pl. 7, fig. 2), are found in open sites in western Nevada
in strata that also contain horse and camel bones. Subsequent dis-
covery of the same type points in a layer of horse dung in a cave
(Etna Cave; Wheeler, 1942) about 100 miles north of Gypsum Cave
considerably strengthens the argument and indicates that the original
assumption was probably correct.
There is some difficulty, as in the case of Sandia Cave, in dating the
material from Gypsum Cave. In the bottom levels were water-borne
deposits in which were camel and horse bones. Above them were
silts left by standing water. The top surface of the latter gave
evidence of a period in which there was considerable evaporation, and
in places it was solidified by mineral substances that had been carried
in solution. The earliest traces of the giant sloth were found on
this surface and in places they were partially covered by a stalagmitic
formation. From that level to the top of the deposits the strata were
wholly dry and gave every indication of always having been so. The
artifacts and other evidence of human occupation were found only
in the dry layers. Botanical specimens obtained from the latter rep-
resent an arid flora comprising plants that are present in the region
today, although some of them live only at higher elevations. The
water-deposited layers, because much moister conditions than have
prevailed at any subsequent period would be required to produce them,
have been correlated with the last great rise in the level of ancient
Lake Lahontan in Nevada. This is believed to have taken place
during the pluvial stage mentioned in the discussion of the Folsom
410 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
and Sandia remains. As the era of aridity had already set in before
the arrival of the hunters, even though their appearance was com-
paratively soon after its beginning, the initial occupation of the cave
is believed to have taken place early in the Recent period.
Evidence for a relatively ancient group in southern Arizona was
found in Ventana Cave (pl. 8) in the Castle Mountains (Haury,
1943). There in the bottom of approximately 15 feet of deposits
were stone implements accompanying bones from the native horse,
giant sloth, tapir, and bison. The artifacts were projectile points,
_ choppers, scrapers, and gravers, a complex very similar to the Folsom
except that the points were not fluted. They approximate the gen-
eral Folsom shape, but no attempt was made to produce the facial
channels (pl. 9, fig. 1). The assemblage of bones and artifacts was
in a lime-cemented layer of volcanic debris. This conglomerate, sup-
plemented by other indications of water action, is good evidence for
a decidedly wet period in that part of the Southwest. The combina-
tion of heavy precipitation and an extinct fauna again suggests a
pluvial condition comparable to that previously discussed and, al-
though geologic studies at the cave have not yet been completed,
possibly a terminal Pleistocene or beginning Recent age.
Important evidence bearing on later developments in the area was
also found in Ventana Cave. Artifacts in the layers above the stratum
containing the old material trace the progress of a cultural develop-
ment from a simple hunting, food-gathering economy through the
acquisition of agriculture and the pottery-making industry and sub-
sequent agricultural and ceramic stages to historic times. The strata
containing this series rested disconformably on the conglomerate, in-
dicating a break in the continuity of occupation. The hiatus prob-
ably represents a fairly long interval because during that period
modern fauna replaced the old animals and there was marked change
in the types of cultural objects.
Recent erosion and the cutting of gullies or arroyos in the south-
western corner of New Mexico, in southeastern Arizona, and in the
adjacent area just across the border in northern Mexico have exposed
hearths, artifacts, and other traces of human inhabitation. The
materials from these sites have been called the Cochise Culture and
have been grouped into three stages or sequent phases on the basis
of their typological traits, the nature of their geologic provenience,
and the associated fossils (Sayles and Antevs, 1941). The oldest of
the phases occurs in sand-gravel deposits that also contain bones of
the native horse, camel, bison, mammoth, and extinct wolf, prong-
horn, and coyote. Hickory charcoal is found in the same level. This
kind of wood no longer grows in the region as it requires much more
moisture than is now available. The layer of sand and gravel has
been interpreted as being a flood-plain deposit from a permanent
NEW WORLD PALEO-INDIAN—ROBERTS 411
stream, and this also points to the need for much heavier precipi-
tation. Study of the general area indicated that only during the last
' pluvial was it wet enough to support the growth of hickory and to
supply water for such a stream. In combination with the remains
of extinct animal forms this factor again implies a terminal Pleisto-
cene age for the artifacts. Most of the latter are grinding or hammer-
ing stones; there are only a few knives and scrapers and no projectile
points. The absence of points is somewhat puzzling. It is possible
that bone or hard wooden points were used and that these have not
been preserved in recognizable form or have completely disappeared.
From present evidence it seems that the culture had an economy
based on food gathering. In the subsequent stages more flaked im-
plements were made, and there is some indication of a certain amount
of hunting. The second and third stages fall in the Recent period
and material from them correlates closely with that in the levels
in Ventana Cave lying between the disconformity and the upper strata
containing the recent remains (Haury, 1943).
Implements from Pinto Basin and Lake Mohave, in the desert area
in southern California, practically duplicate those in the upper levels
of Ventana Cave and the later stages of the Cochise. Lake Mohave
and Pinto Basin are formations attributed to the pluvial of late Pleis-
tocene times, and artifacts are found along their old beach and shore
lines. From this it has been suggested that the implements must have
been contemporaneous with the ancient lakes (Campbell, 1935; Sym-
posium, 1937). Because this material is mainly from the surface, and
in view of the fact that similar artifacts in the Cochise Culture and
Ventana Cave are definitely Recent, it does not seem that they should
be considered evidence for an early occupation of the district. That
people actually were in the California desert area at approximately
the same time as those who made the artifacts present in the bottom
of Ventana Cave seems probable, however, as sporadic occurrences of
implements suggestive of the Folsom Complex are found there and
one supposed Folsom site has been reported although there are no data
on it thus far.
In north-central Texas deeply buried occupation levels (pl. 9, fig. 2),
hearths, and graves in the banks of various streams and their inter-
mittent tributaries yield information and specimens that suggest rela-
tively early inhabitation of that region. The oldest appears to center
in the Abilene district, where there are a number of stratified sites in
which different types of artifacts are found at depths ranging from
4 to 30 feet beneath the surface (Ray, 1930). In the lowest levels are
charcoal, crude tools of the heavy scraper, hand-ax, and chopper types,
and thick leaf-shaped points thinned at the base by the removal of a
broad, short flake from one side. This treatment is suggestive of that
412 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
noted on some of the Sandia type 2 points. There may be no relation-
ship between the two forms, but it is interesting to note that the Sandia
type 2 point found near Abilene apparently belongs in the same hori-
zon as the Abilene type. In the deposits above occur a variety of
implements and a sequence of point types that are considered compo-
nents of a single complex, one that has been named the Clear Fork
(Ray, 1938; Roberts, 1940, pp. 74-76). The upper strata produce
artifacts attributable to the Texas Indians of late pre-Columbian
times.
The implements of the Abilene Complex are found in the top and
_along the deeply weathered surface of an old soil or gumbo profile
and in the bottom of an overlying series of silts laid down by wide-
spread, successive, slack-water sheet floods. The Clear Fork Com-
plex, beginning above the Abilene horizon, occurs in these same silts
and shows progression from level to level toward the surface. The
gumbo profile has been identified as Pleistocene. The first tentative
conclusions were that it possibly correlated with the Illinoian glacial
substage (Leighton, 1936), but subsequent evidence suggests that it
was more likely mid-Wisconsin or even later in the period. The lower
strata in the silts are regarded as belonging to the end of the Wiscon-
sin substage and grading into the beginning of the Recent, whereas
the higher levels are definitely Recent. Abilene and fluted points of
the generalized type occur in the same horizon, and the smaller,
better-made Folsom projectiles are found in association with older
forms of the Clear Fork Complex. In addition, fossil mammoth, ex-
tinct bison, other vertebrates, and Mollusca remains—generally con-
sidered as representing a Pleistocene fauna—come from the same
levels. Hence it seems that in this area there is further evidence for
a late Pleistocene or possibly slightly earlier occupation.
Various archeological finds of greater or less significance relating
to this general problem have been made in other parts of Texas, in
Kansas, Nebraska, Wyoming, Utah, Oregon, northern California,
Minnesota, parts of Canada, and Alaska (Roberts, 1940; Sellards,
1940), but space limitations prevent their consideration. In the main
they tend to corroborate the evidence from the discoveries already
discussed.
NORTH AMERICAN SKELETAL MATERIAL
Human skeletal material from the older horizons is relatively rare,
and the information furnished by it is not as satisfactory as that
from the cultural objects. This is in large part attributable to the
fact that antiquity must be determined by the geologic age of the
strata in which the skeletal remains occur rather than by the morpho-
logical and metrical features of the bones themselves. Associated
. So
i
NEW WORLD PALEO-INDIAN—ROBERTS 413
archeological and paleontological objects are an important aid, al-
though they also may frequently be inconclusive. The types of men
responsible for the Sandia Cave, Folsom, Ventana Cave, Gypsum
Cave, and similar complexes are not known, as no human remains
have been found in association with implements from any of those
cultural patterns. A skeleton sometimes thought of as a possible
example of Folsom man was discovered in a bank of the Cimarron
River in northeastern New Mexico some 16 miles east of the original
Folsom site. The bones were in a water-borne deposit 13 feet 6
inches below the present surface and, from the degree of their fossili-
zation and a tentative correlation between their situs and a nearby
buried stream bed and the latter with the bison quarry, were believed
to be as old as, if not older than, the artifacts and animal bones at
that location (Figgins, 1935). This conclusion has never been con-
firmed, however, and as there were no accompanying archeological
specimens it cannot be said that the skeleton was that of Folsom
man. It is unquestionably Indian, and certain characteristics of the
skull—its definite long-headedness, heavy brow ridges, and deeply
depressed nasal root—are rather primitive (Roberts, 1937), but the
bones themselves give no hint of the time when the individual lived.
On the basis of the physical features he could be late Pleistocene or
early Recent or, on the other hand, a modern Indian. Unfortunately,
the geologic evidence needed to reach a verdict. is not available.
One fragmentary skeleton was recovered from the oldest level of the
Cochise. The bones were so broken and so many pieces were missing
that it was difficult to make a determination of the physical type.
After careful study, however, it was concluded that the individual
was one of the small, southwestern longheads belonging to the Basket
Maker group. The Basket Makers were the first agricultural pottery-
making peoples in the Pueblo area, in the period from the beginning
of the Christian Era to about A. D. 600, and although they had some
primitive features, they were essentially modern Indians. They are
believed to have been in the region long enough to have made the
transition from a simple nomadic-hunting economy to that of the
hunting, food-gathering, and subsequent agricultural pottery-making
stages that are well known from excavations in the Pueblo region.
The Cochise occurrence may be considered substantiation for their
relatively early appearance in the Southwest, although it might be
regarded as an indication that the Cochise is not as old as has been
suggested.
In the Abilene district, burials are found at varying depths in
the silts containing implements of the Clear Fork Complex. Some
were unquestionably subsequent penetrations into the silts, but others
seem to date from the period when they were forming. The best
414 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
example of the latter was brought to light when high water in the
Clear Fork of the Brazos River caved off a section of bank some 60
miles northeast of Abilene and exposed a grave 21 feet below the
present valley floor (Ray, 1943). Portions of the skull and all the
hand bones were swept away by the flood. Enough remained, though,
to give a good indication of the type of individual buried there. The
profile of the deposits showed an unbroken series of strata extending
across the top of the grave and rising from what had been the level
of occupation at the time when it was dug to the present surface.
There is no question that the burial was made in the early stages of
the deposition of the silts and that it was as old as the lowest of the
overlying strata. As these are in the portion of the silts identified
as probably being late Pleistocene in origin, the skeleton would be of
similar age. The tip end from a small stone blade was found in the
grave but, unfortunately, it is not sufficiently characteristic to indi-
cate its cultural affinities. The bones show that the individual was a
tallish, moderately robust male about 40 years of age. He had excep-
tionally heavy brow ridges, a long head, and a broad, rugged lower
jaw. The skull in some respects might be approximated by occasional
recent Indians, although in the main it agrees more frequently with
the more primitive forms of morphologically modern-type man found
in America. Since from its general features the skeleton could be
that of a Paleo-Indian, there is nothing anachronistic in its being
found in deposits that are late Pleistocene or early Recent in age.
Other remains from deep burials in the Abilene region have shown
similar characteristics and have been considered as exemplifying a
very primitive American Indian, probably one of the earlier strata of
the American population (Hooton, 1933).
One of the few examples of a burial attributable to a fairly old
horizon and accompanied by artifacts was that of the Browns Valley
man in Traverse County, Minn. (Jenks, 1937). It was found in a
gravel pit while material was being removed for use in highway con-
struction work. The bones were in a grave that had been dug in late
glacial or Pleistocene gravels subsequent to their deposition but prior
to the formation of a thick humus layer that rested on them. Con-
clusions based on geologic studies of the site are that the interment
was made in early postglacial times, that is, in the beginning of the
Recent period. The associated implements consisted of three points
and two knife blades. In the original description they are classified
as Yuma-Folsom because of certain features that are suggestive of
each. In view of later information about those types, as previously
mentioned, it seems that Browns Valley artifacts would be a better
designation. They are good examples of one of the older patterns in
cultural material and merit a distinct name. ‘The skeleton was that
ws
NEW WORLD PALEO-INDIAN-—ROBERTS 415
of an adult male and, as in the cases already discussed, the skull was
of the long-headed variety with strong development of the brow
ridges, and a broad, heavy jaw. The individual was undoubtedly an
American Indian, but he differed from the recent Indians known to
have occupied that particular region.
Another Minnesota skeleton, the remains of a girl about 15 years
of age, has been proposed as an example of the physical type of the
Paleo-Indian living in west-central Minnesota in late Pleistocene
times (Jenks, 1986). The matter of its antiquity has been questioned
in some quarters, however, and there has been considerable contro-
versy over its proper status. The remains were discovered by work-
men repairing a stretch of highway in Otter Tail County when the
grader blade, making its deepest cut in the middle of the roadbed,
exposed fragments of a broken clam shell. Stopping to investigate,
the workmen found the frontal of a human skull beneath the bits of
shell and a short distance away a piece of what they thought to be
bone but which later proved to be the greater part of an implement
made from antler. The road boss interrupted work with the heavy
equipment until the find could be uncovered and within the space of
2 hours most of the skeleton had been removed. At the start several
of the bones were damaged by the shovels being used in the digging.
When they were discarded for small hand tools the results were bet-
ter and most of the material was recovered in fairly good condition.
The skull had been crushed by the weight of the grader wheel but had
not actually been touched by it, nor had the grader blade come in con-
tact with any of the other bones. A shell pendant found among the
ribs and vertebrae probably had been worn suspended from the neck.
During the progress of the disinterment a number of the men not
participating in it watched the process, studying and discussing the
nature of the surrounding earth. From their statements, and from
the profiles made by the highway engineer prior to the original con-
struction, it was concluded that there had been no break in the over-
lying strata, and that the body had not been buried intentionally but
had been covered by the deposition of silts around it after it had
come to rest at that particular spot. The repairs on the highway
were completed, and the bones were turned over to the University of
Minnesota. After they had been studied it was evident that they
exhibited a number of primitive characteristics and further exami-
nation of the place where they were found was deemed advisable.
On two different occasions traffic was diverted and the site reopened.
These investigations demonstrated beyond question that the skeleton
had come from that location. Fragments of bone were obtained that
fit pieces recovered in the initial digging, and in addition animal and
bird bones and many segments of turtle carapace were found. While
416 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
the pit was open, geologists studied the deposits and came to the con-
clusion that they were varved clays of a glacial lake, subsequently
named Lake Pelican. There is no question about the identification of
the silts, but there has been contention over the nature of the burial.
Many think it was contemporaneous with the clays, and the testimony
of the workmen and the highway engineer is good basis for such
belief, while others hold that it must have been a later penetration.
Furthermore, there has been contention as to whether it was inten-
tional or accidental, whether the body had been placed in a grave or,
as has been suggested, the girl fell from a boat or through a hole in
the ice, drowned and sank to the bottom where she was covered with
gradually settling sediment. The problem is complicated even more
by arguments over possible evidence for slipping and disturbance in
the clays and the chance that the skeleton may have been intrusive.
Unfortunately, the issue can never be settled to the satisfaction of all
because of the manner of its discovery and its location beneath a
highway.
The artifacts are of little help because similar antler and shell ob-
jects might be found accompanying any burial in that region, even
those dating as recently as early historic times. The fragments of
bone from muskrat, wolf, loon, and turtle carapace also present in
the pit are from species that could be Pleistocene but also are mod-
ern and indicate climatic conditions little different from those of
today, hence cannot be stressed as evidence. Because of all these fac-
tors opinion is about equally divided; some consider the age as late
Pleistocene and others as clearly Recent. Careful review of all
phases of the problem, however, would seem to indicate that the prob-
ability of a late Pleistocene dating outweighs that of a Recent age.
The skeleton has a number of primitive features, the most outstand-
ing being in the skull. The forehead is low and sloping, with promi-
nent glabella. There is a backward extension of the cranial vault to a
large occiput with a large projection to the rear and evidence for a
high area of attachment for the neck muscles. The nose is relatively
small and narrow, lacks a nasal sill, and has a poorly developed nasal
spine. There are deep subnasal gutters, and there is marked alveolar
prognathism. Obvious lack of reduction is apparent in the jaws and
teeth, a feature usually considered definitely primitive. The lower
molars in absolute size are larger than any of those in the lower
jaws of 10 late Pleistocene men in Europe, and this in conjunction
with other less developed characteristics is regarded as good evidence
for the remains being those of an early type of modern man. There
is no reason from the standpoint of their osteology why they could
not be as old as the silts indicate. On the other hand they do fall
within the range of variation in the modern Sioux and are believed
NEW WORLD PALEO-INDIAN—ROBERTS 417
by some of the physical anthropologists to belong in that category.
In this connection it may be mentioned that this is the only example
among the many purported early American skeletons where the skull
is not definitely of the long-headed type. In this case it is
mesocephalic.
THE MEXICAN ARBA
There has been little evidence thus far for Paleo-Indians in the
Mexican area. No Folsom-type points, with the exception of the
two in Sonora about which practically nothing is known and one
possible fluted blade from Tamaulipas (Prieto, 1912, fig. 13), have
been found south of the Rio Grande. Some discoveries suggestive
of certain antiquity have been made, yet none has been demonstrated
-to compare in age with Sandia, Folsom, and similar complexes. In
fact it is agreed that. they are much more recent (Martinez del Rio,
1948, pp. 168-170). It seems improbable, however, that no such finds
will be made; there is always a chance that one will come to ight. Up
to the present so little work has been done in the northern districts
that, with the exception of knowledge of the occurrence of some
scattered late village sites and protohistoric ruins and a few caves that
date within the Christian Era, there is virtually no information on
the remains in that area. Bison roamed as far south as southern
Durango and were in the region around Monterrey in Coahuila as
late as the beginning of the seventeenth century (Hornaday, 1889,
p. 882), and there is the possibility that older species may have occupied
the area as well because there are several large deposits of bones
weathering from the beaches around the beds of lakes that must have
dried up several millennia before the coming of the Spaniards. Hasty
examination of these bone beds indicated that much of the material
was bison, but no attempts were made to collect specimens or to deter-
mine the species. It is not improbable that some of the older forms
are represented there, and inasmuch as the earlier peoples were mainly
hunters and followed the game in its migrations, it would not be sur-
prising if, eventually, bones from extinct bison accompanied by types
of implements made by the Paleo-Indians were found there. If the
generally accepted ideas about the peopling of the New World from
Asia are correct, the Mexican plateau must have served as a broad
highway to Central and South America, and although it may be
difficult to find, there should be some evidence of the migrations passing
that way.
CENTRAL AMERICAN FINDS
Finds in Central America show that the bison formerly ranged
much farther south than Mexico. A horn identified as bison came
from northern Nicaragua many years ago (Rhoads, 1898), and tracks
418 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
made by bison were recently reported from west-central Nicaragua.
The latter are of more than passing interest because of their associa-
tion with imprints left by barefooted human beings (pl. 10, fig. 1)
as well as with those of other animals and birds. They were un-
covered by quarrying operations in a deeply buried volcanic stratum
at El Cauce, in the outskirts of Managua (Richardson, 1941; Richard-
son and Ruppert, 1942). Studies of the deposits have led to the con-
clusion that the track-bearing layer was produced by a flow of semi-
liquid mud from a vent on higher ground. While the surface was
still sufficiently soft to receive perfect impressions the people and ani-
mals passed over it. Shortly thereafter a thin fall of dry cinders
covered the tracks, preserving and protecting them so that today they
are as sharp and clear as when first made. Subsequently there was
another mud flow and eruption of black cinders and then a rapid suc-
cession of thick mud flows (pl. 10, fig. 2). In the course of time these
layers turned to stone, a phenomenon comparable to that occurring
at Herculaneum after its destruction by Vesuvius in A. D. 79. A
stream forming a channel some 65 feet wide and 10 feet deep then
cut its way through the strata thus formed. Eventually the bed of
the stream filled with silt, gravel, and water-rolled stones. Later the
area was covered by a heavy fall of pumice from the eruption of
a distant volcano, and during the following quiescent interval new
stream channels were cut and a thick soil zone developed. Again
more ashes fell and another soil zone accumulated to be covered in
turn by pumice from a further eruption. Finally the present topsoil
developed to a depth of from 4 to 5 feet. The lowest portion of this
layer is an aeolian deposit representing a period of slow growth
(Williams, in Richardson, 1941). The sequence of events recorded in
this series of strata required considerable time for its consummation,
and although conclusions as to the age of the footprints await the
completion of volcanological studies now under way, it appears certain
that appreciable antiquity is indicated.’
Journals of the conquest period presumably contain no references to
bison for this area, and everything indicates that they have long been
extinct in Nicaragua. Since their tracks and those made by men
are unquestionably contemporaneous, the occurrence would tend to
signify that the human occupation should be regarded as dating from
fairly early times. Lending strength to this assumption is the fact .
that between the footprints and overlying archeological remains are
approximately 10 feet of deposits. Included in the material from
the lowest cultural level of the later manifestations are potsherds from
The work of F. B. Richardson, of the Division of Historical Research of the Carnegie
Institution of Washington, and that of Prof. Howel Williams, of the University of Cali-
fornia, who was cooperating in the investigations, was interrupted by the war but will be
resumed as soon as hostilities have ceased.
NEW WORLD PALEO-INDIAN—ROBERTS 419
a type of ware found only in the earliest ceramic horizon in Guatemala
and El Salvador. This argues for a relatively ancient population in
the Managua district. As the footprints occur at a much greater
depth and must be considerably earlier, it is possible that they consti-
tute the oldest trace of human presence thus far noted in Middle
America and that they will establish the period of migration at a date
some millennia prior to that hitherto postulated.
SOUTH AMERICA
The situation in South America is somewhat different. Numerous
discoveries have been proposed as evidence for an early occupation,
but there is much disagreement over their actual import. Several
factors contribute to conflicting opinions about the problem. In many
portions of the continent there is difficulty in identifying and correlat-
ing deposits. Certain animal forms appear to have survived longer
than in the north, with a corresponding lessening of the significance
of faunal associations. Other complications have resulted from a
rather common tendency to place undue reliance on the typology of
implements, picking and choosing those that suggest antiquity while
failing to consider the remaining components in a complex. Further-
more there has frequently been complete disregard of the situs of the
finds, resulting in anachronic and wholly misleading conclusions.
At the time of its discovery the Punin calvarium from Ecuador
aroused considerable interest, and it is often mentioned as an example
of “early” man from that area. Only the skull was found. It came
from a deposit of volcanic ash in which also were bones from the extinct
Andean horse, a large ground sloth, a so-called camel (the Protauch-
enia), the Andean mastodon (Cordillerion, a “Bunomastodont” not
to be confused with the North American mastodonts), and those from
present-day animals (Sullivan and Hellman, 1925). There was not
an actual association, the nearest animal bones being 50 to 100 feet
from the skull. The discoverer, however, expressed the opinion that
serious consideration should be given to the implied contemporaneity.
The skull falls into the category of one of the three types generally
believed to be characteristic of the oldest stratum of New World
peoples. This particular form has been designated Australoid (Sulli-
van and Hellman, 1925), Pseudo-Australoid (Hooton, 1930), Proto-
* Australoid (Dixon, 1923), and Fuégido (Imbelloni, 1937). The ques-
tions of nomenclature, identifications, somatological inferences, and
true significance of the type are too varied and complex for considera-
tion in this presentation. The Punin calvarium is admittedly an
archaic Indian form and could be relatively ancient but, as in the case
of the North American skeletal material, the age must be based on
geologic—paleontologic evidence and not on the nature of the skull
420 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
itself. The ash deposit has not been correlated with any specific geo-
logic horizon. The faunal assemblage occurring in it is generally
considered as Pleistocene, and were it not for the human remains, the
layer no doubt would have been regarded as of that age. Yet other
evidence, such as that of the “Bunomastodon” (Cuvieronius) found
near Alangasi, Ecuador (Uhle, 1930), suggests that the animals con-
tinued well into the Recent period before becoming extinct. The fact
that the quantity and variety of animal life in the Punin district has
been much poorer in modern times than it was in the period when the
voleanic ash was being laid down indicates some antiquity, yet the
evidence for early occupation is not as convincing as is desired.
The Confins man from the highlands of the state of Minas Geraes, °
Brazil, was a more satisfactory discovery (Walter, Cathoud, and
Mattos, 1987). This skeleton was found in 1935 in a cave in the Lagoa
Santa region where the Danish naturalist Lund made his extensive and
well-known collections over a century ago. The entrance to the cave
was uncovered during the course of excavations in an Indian shelter
and burial ground dating from about the conquest period. As the
blocks of fallen stone and conglomerate were removed in the search for
graves, the entrance was gradually exposed and ultimately stood en-
tirely clear so that the cave was accessible. There were no traces of
human occupation in the upper alluvial deposit of the floor, and, as
careful investigation showed that the entrance had been sealed during
pluvial times, it was quite evident that the existence of the cave was
not known to the people who used the shelter and buried their dead at
its mouth. It was not until the fourth year of exploration in the
interior of the cave that the human remains were found. The bones
lay beneath approximately 7 feet of alluvial silts that had been sealed
in by a layer of stalagmite. Natural rather than intentional burial
was suggested by the position of the remains. The body evidently had
rested on the surface and gradually was covered by sediments carried in
by successive floodings from a nearby lake. In the same stratum were
bones from the giant sloth, large llama, an extinct horse, tapir,. bear,
giant capybara, peccary, and mastodon. This assemblage constitutes
what is usually regarded as a typical Pleistocene or pluvial age fauna
in that area. No artifacts accompanied the skeleton and none were
found in the deposits in the cave, hence there was no indication of
cultural affinities. The skull is of the long-headed variety with low
forehead and, although comparable to the Lagéa Santa type in its
hypsicephaly, presumably does not belong in that category. Students
who have examined it consider it one of the most primitive forms of
Paleo-Indian thus far found in South America.
Contemporaneity between the human and animal remains is in-
disputable and appreciable antiquity is indicated both by the depth of
NEW WORLD PALEO-INDIAN—ROBERTS 421
the overlying silts and the thickness of their stalagmitic cover. The
high-water level in Lake Confins, from which the silt-bearing flood-
waters are believed to have come, at present is 65 feet below the bottom
of the cave. Throughout historic times there has not been sufficient
water to produce overflowing into the cave, and consensus is that only
near the end of the Pleistocene or corresponding pluvial period was
there adequate precipitation to cause such phenomena as the deposition
of the silts and the formation of the stalagmite. At present knowledge
of that period is too incomplete to provide a basis for chronological
estimates on the age when the pluvial came to an end in the area. Some
of the animals represented in the faunal assemblage seem to have sur-
vived into relatively recent times and consequently are not much help
as acriterion. The Confins man was unquestionably “early” insofar
as his relationship with subsequent inhabitants of the region is con-
cerned, but just how ancient he actually was is a problem still waiting
to be solved.
The Sambaquis, shell heaps scattered along large sections of the coast
of Brazil and on the banks of certain rivers in the interior, should be
_ mentioned, although their value as evidence for an early occupation is
debatable. There is considerable variation in the size of these forma-
tions. Some of them measure 300 to 350 feet in length and 50 to 80
feet in depth. In most cases, however, they are not as extensive and not
more than 10 to 20 feet deep. Many are located some distance from the
present shore line. This indicates that they were formed when the
sea was at a higher level, and for that reason they are regarded as
being of considerable age. They have been referred to as evidence for
a fairly early and dense population in the area because many people
have believed that all were of human origin despite suggestions from
time to time to the effect that most of the large ones probably were the
product of natural forces. Recent investigations tend to substantiate
the latter point of view (Serrano, 1938). None of the shells in the
larger heaps have been opened, and such traces of human activity as
have been discovered apparently were intrusions and not contem-
poraneous material. Various small heaps and occasional portions of
some of the medium-sized ones, however, consist of kitchen-midden
deposits or refuse and definitely are man-made. The small heaps lo-
cated farthest from the sea in the southern provinces, especially in the
Sao Paulo district, yield the oldest-appearing artifacts. A simple cul-
ture in strong contrast with that of historic times is represented. Stone
and bone implements comprise most of the complex. The stone tools
are as a rule roughly chipped, but they are polished along the edges.
Potsherds are sometimes found on the surface or in the upper part of
the top layer of such mounds and the evidence suggests a late pre-
ceramic group just beginning to acquire pottery. This, in combination
422 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
with the polished edges on the stone artifacts, points to a later horizon
than that indicated for some of the complexes previously considered.
Further investigations are desirable to establish more precisely, if pos-
sible, the exact status of these manifestations because finds farther
south furnish a basis for the assumption that a relatively old culture
may have existed in this region.
In Argentina there has been active interest in the subject of “early
man” ever since the discovery of bones from extinct animals and
stone implements in the Mar del Plata region and the announce-
ment of a Homo pampaenus (Ameghino, 1909). This area is very
productive archeologically. There are many sites where house re-
mains, pottery, and metal objects are found, but in addition there is
an older horizon which is characterized by a different human physical
type and an implement complex containing only stone and bone tools.
Furthermore there are sporadic occurrences of artifacts, presumably
in association with extinct faunal material, and human skeletons that
have been presented as evidence for varying degrees of antiquity.
Arguments over their validity have flourished for many years, and
they still furnish a fertile field for debate. It is not within the scope
of the present paper, however, to review and discuss all these finds.
Efforts to demonstrate that the cradle of the human race was in South
America stirred a controversy that produced a voluminous literature.
Information on the subject may be found in the numerous publica-
tions detailing both sides of the question. Consensus is that in the
beginning entirely too great an antiquity was proposed for these
remains, but that some of the theories advanced in explaining them
may have some justification when adapted to a more conservative time
scale,
Geologic evidence in Argentina, as elsewhere in South America and
in many portions of North America, tends to be confusing and to
promote errors in correlation and cross dating. Finds frequently
are made in dune districts where artifacts are uncovered by wind
action and are left exposed in the bottoms of large depressions or
playas (Greslebin, 1930). The situation is comparable to that in
the so-called blow-outs of the western plains in the United States.
The relationship between objects lying on the top of a hard sub-
stratum is always problematical because they may have been at
different levels before they were dropped to a common surface when
the surrounding earth was blown away. Also, some of the specimens
may have weathered from the top of the lower layer, as often happens
in the case of animal bones, and there may seemingly be an associa-
tion between artifacts and an extinct fauna when the man-made
objects actually belong in a later horizon. For that reason such oc-
currences are properly open to doubt. That the degree of minerali-
NEW WORLD PALEO-INDIAN—ROBERTS 423
zation in human and animal bones is not a reliable criterion for
antiquity apparently has been overlooked or disregarded by some of
the advocates for an early occupation of this area. Reliance on the
typology of implements also is misleading because, as has been dem-
onstrated elsewhere, some tool forms persisted over long periods, and
similarities between Old and New World specimens do not constitute
proof of their contemporaneity. Artifacts may be paleolithic in type
but not in age, a factor that has been forgotten by many arguing
considerable age for certain specimens in this locale. However, some
discoveries indicate that occupation of this area was not wholly a
recent event. This is particularly true of a number made in late years,
which suggest that while the antiquity is not as great as earlier claims
would make it, the age probably compares favorably with that gen-
erally recognized for North America. Because of finds made in
southern Patagonia, evidence from future investigations in Argen-
tina will be studied with considerable interest.
A definite association between human remains, an extinct fauna, and
an interesting series of artifacts has been reported from southern
Patagonia, in Chile just south of the Argentine border (Bird, 1938).
The evidence was found in caves and a rock shelter. One of the caves,
named Palli Aike, was located in an old volcanic crater and contained
deposits which in places attained a depth of 8 feet 6 inches. The upper
5 feet of the deposits was composed of fine, dry dust with an admix-
ture of broken and burned bones and some stones. This stratum
rested on a layer of volcanic ash that had a maximum thickness of 2
feet. Throughout the ash and scattered: over the original rock floor
were large blocks of lava that had been erupted into the cave at the
same time as the ash. The upper 18 inches of the deposits contained
stemmed arrow points, knives, various kinds of scrapers, and bolas.
Among the points from the top 6 inches were finely made specimens
of the type attributed to modern Ona Indians. Larger and cruder
stemmed forms occurred throughout this 18-inch level. Stemless
points and other kinds of implements came from the next layer, 18
inches to 3 feet below the top. Various types of scrapers and other
stone and bone implements, but no points of stone (the few found
were made of bone), came from the stratum between 3 feet and 5 feet.
On the surface of the underlying layer of volcanic ash were tools of
stone and bone, debris of occupation, fireplaces, and broken and burned
bones from the ground sloth and native horse. Embedded in the top
of the ash was the stem from a different type of stone point. Toward
the back of the cave three cremation burials were found along the
base of the wall in hollows in the top of the ash. This provided im-
portant evidence of contemporaneity between human remains, extinct
animal bones, and artifacts in what probably is the first well-authenti-
619830—45-—28
424 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
cated occurrence of the kind in the New World. The ash layer con-
tained several partial sloth skeletons, and it was obvious that the ani-
mals had used the cave as a shelter and had died there. Nothing sug-
gested that they had been killed by Indians, but that the latter had
been there during the early period was shown by the charcoal and
stone flakes present in the debris on the original floor.
Some 20 miles west of Palli Aike, in the valley of the Rio Chico,
was a formation called Fell’s Cave, although strictly speaking it was
a shelter rather than a true cave (pl. 11). It had been formed at
some time when the river undercut the canyon wall. The deposits
there were slightly over 8 feet in depth and contained another in-
teresting sequence. The top layer consisted for the most part of
sheep dung and produced no artifacts. The stratum below it, how-
ever, yielded evidence of four cultural horizons. There was no
structural change in the geologic debris, and clearly marked lines of
demarcation were absent, but the archeological and faunal material
was sufficiently differentiated to demonstrate the levels. In the latest
horizon were Ona-type points and some of the larger, cruder, stemmed
forms like those present in Palli Aike. The next level contained only
the latter kind of points, while below it were stemless points and
blades. Scrapers of various kinds occurred throughout the stratum,
but it was only in levels containing stone points that bolas were found.
Associated with this material were bones from the guanaco, fox, and
bird. There was a marked change in the proportions from the top
downward until at the bottom, which was the bone-point horizon,
bird and fox bones predominated and those from the guanaco were
only sporadic.
Underlying the above stratum was a sterile layer, 15 to 28 inches
thick, composed mainly of slabs, blocks, and disintegrated pieces of
conglomerate that had fallen from the ceiling. This debris com-
pletely sealed off from the upper levels a layer of occupation refuse
ranging from 3 to 9 inches in depth. Numerous artifacts, stone flakes,
and bone fragments were scattered through it, and there were four
hearths where fires had burned. Broken and burned bones from the
giant sloth, native horse, and guanaco were mixed with the charcoal
and ashes. Artifacts in the layer were bone implements, various
kinds of scrapers, cylindrical rubbing stones, chopping stones, and 14
roughly made stemmed points of stone. These specimens show that
the first occupants of the shelter had an entirely different material
culture from those who used it later. The stem from a point found
in the top of the ash layer in the bottom of Palli Aike Cave is from
the same type as all but one of the points from the bottom stratum
in the shelter and serves, with those from upper levels, to demonstrate
that the same type sequence prevailed in both locations (pl. 12). The
NEW WORLD PALEO-INDIAN—ROBERTS 425
single differing point from the bottom level of the shelter in its out-
line suggests a Folsom point, but actually it was not of that type.
During the interval between occupations, that characterized by the
rock fall, the horse and giant sloth disappeared and the guanaco be-
came rare. The latter as a matter of fact did not return in sufficient
numbers to become an important food item until the closing days of
the stemless-point period or third cultural horizon.
At no great distance from the shelter and in the side of a hill called
Cerro Sota is a long, narrow cave. The upward-sloping floor was
covered at the inner end with a deposit of fine, dry dust 5 feet deep.
In the lower 3 feet of this debris were many fragments of native horse
bones and a few from those of the sloth. There were no artifacts,
and the only signs of fire were those associated with the cremation
burial of a group of 8 adults, 2 children, and 2 infants. The bodies
had been placed in a hollow at the rear of the cave, had been sur-
rounded with grass and then burned. There were no accompanying
artifacts to indicate the cultural affinities of the remains, but it seems
likely they belonged to the first or oldest horizon. The fact that the
earth above the burial contained broken horse bones suggests such a
correlation. The skeletal material both from this cave and Palli Aike
shows that the people were long-headed, had general Indian charac-
teristics, and in some traits resembled those whose remains were found
in the Lagoa Santa Cave.
Unquestionable association with an extinct fauna indicates certain
antiquity for these finds, but again the question of when the animals
disappeared is all important and there still is no satisfactory answer.
This part of Patagonia was on the edge of the extension of the Pleisto-
cene ice sheet in that area, and a possible correlation between the
retreat of its last advance and other phenomena suggest that people
may have been in the region to the east prior to the recession. At the
time the excavations were made, a relative chronology was developed
on the basis of a correlation between evidence for marked land rises,
a change in the level of the Rio Chico, the subsidence of Laguna
Blanca located some 60 miles west of Palli Aike, and clear indications
that the volcanic eruption recorded in the bottom level of that cave
was the oldest in the sequence. The initial occupation of Fell’s Cave
apparently preceded the eruption, and the third period seems to have
ended with the drop in the level of Laguna Blanca. Independent
studies have suggested that the subsidence in the lake was synchro-
nous with the last ice retreat, and if this were the case it would tend
to establish appreciably early inhabitation in the area. The native
horse and the giant sloth seem to have disappeared soon after the
volcanic disturbance, when there may have been a rather severe but
relatively brief fluctuation in climate. These factors give no real
426 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
date, of course, but they do furnish a basis for making estimates. This
will be considered in more detail in connection with the discussion of
the ages which have been assigned to all such finds.
SUMMARY AND DISCUSSION
It is evident, from the manifestations discussed in preceding pages,
that man had reached the New World when large portions of North
America were still covered by remnants of the Wisconsin ice sheet.
The physical characteristics of such remains as have been found, as
well as those of the later Indians, indicate an Asiatic origin and subse-
quent migration. This spread probably did not take place as a single
mass movement but as a series of continuing migrations by relatively
small bodies of people over a long period of time. When this began
and the routes followed are matters about which opinions differ. Most
students of the problem, however, agree that the bulk of the aboriginal
population arrived by way of the Bering Strait region and from there
gradually spread over North America, through Middle America, and
into the southern continent. The great central plain in Alaska and
the lowlands bordering Bering Sea and the Arctic Coast were not
glaciated during the last stage of the Pleistocene. Moreover, there
was an open corridor along the eastern slopes of the Rocky Mountains
in the period just after the climax of the Wisconsin. As a consequence
it was possible for men and animals to pass from central Asia to the
tip of Siberia and across to Alaska, eastward to the Mackenzie River
and thence southward into the northern plains. Another route by
way of the upper Yukon and its tributaries, the Liard and Peace
River valleys, opened subsequently, and not long after this still another
became available. It led south along the Fraser River, between the
Rockies and the Coast Range, and into the Great Basin. The presence
of artifacts, old camp sites, and bones from extinct species of animals
found in various places demonstrates that full advantage was taken
of these several natural highways.
The first migrants were hunters and they undoubtedly traveled in
small groups. According to present evidence they followed two main
lines of dispersal, one along the eastern slopes of the Rockies, some
continuing on south toward northeastern Mexico, and others spread-
ing out over the plains to the more southerly reaches of the Mississippi
River and from there to eastern portions of the country. It may be
pure coincidence, but it is interesting to note in passing that the
northern boundary of the distribution of sites attributable to these
people approximates the line of moraines left by the retreating glaciers
following the climax of the last Wisconsin substage. The other
movement seems to have been along the plateau between the Rockies
and the Coast Range into the Great Basin, southern California,
NEW WORLD PALEO-INDIAN—ROBERTS 427
Arizona, and probably from there into northwestern Mexico. The
latter movement may have continued along the strip of coast west
of the Sierra Madre Occidental, while the groups from the eastern
division who proceeded southward presumably traversed the plateau
between the Sierra Madre Oriental and the Sierra Madre Occidental.
Eventually descendants from both must have passed through the
Middle American funnel and into South America, where some pos-
sibly spread along the Venezuelan Andes and into the plains of the
Orinoco and others continued southward along the Andes to southern
Bolivia, where they scattered southeastward across the Gran Chaco
into Brazil, south of the Amazonian Forest, and on south into Argen-
tina. Some may have crossed the range to the west and emerged in
the coastal belt south of the Atacama Desert (Sauer, 1944, pp. 558-559).
The major movements that provided most of the Indian populations,
however, appear not to have developed until later when the Recent
period was well established. Such accretions as may have come by
sea were too late to affect the older groups and too small to play much
part in the later developments.
Although in many cases they apparently outlived the geologic
Pleistocene, many of the animals killed by the early peoples consti-
tute what are usually considered Pleistocene forms. They seem to
have survived through the transition to Recent times and then to
have become extinct rather suddenly. Causes of this widespread and
rapid disappearance are not known. That the Paleo-Indians may
have been a contributing factor through slaughter of the animals and
the introduction of diseases to which they were particularly suscep-
tible has been suggested. Other phenomena, no doubt, were also in-
volved, and future work may produce the information necessary to
a solution of this interesting phase of the problem. In this group of
mammals in North America were: mastodonts, mammoths, ground
sloths, horses, camels, and tapirs, from families now extinct; antilo-
caprid, the giant beaver, the short-faced bear, saber-tooth cat, giant
cat, musk ox, and bison, from genera and species now extinct but from
families still persisting. In South America those from extinct fami-
lies were: ground sloths, glyptodonts, “Bunomastodonts,” horses from
the short-legged type derived from the late Pliocene immigrant, and
the Pleistocene H'guus; while extinct genera and species from per-
sisting families are represented by an armadillo, the short-faced bear,
and saber-tooth cat (Colbert, 1942). The early inhabitants of both
North and South America probably were contemporaneous with other
animal forms, but their remains either have not been found in direct
association or the association was too doubtful to receive consideration.
Since many of these animals seem to have become extinct at a rela-
tively recent date, associations between their bones and artifacts do
428 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
not necessarily indicate any great degree of antiquity. When such
occurrences are in deposits that can be correlated with geologic phe-
nomena, attributable to the late Pleistocene, however, dating the as-
semblage as of that time is justifiable. Some of the North American
evidence indicates that the earlier migrants were in the New World
at the end of that period and on the basis of certain interpretations of
the Patagonian manifestations it would appear that some must have
arrived well before its termination.
To describe in detail the different implements comprising the various
complexes and those occurring in sporadic assemblages of bones and
artifacts has not been possible in the bounds of the present discussion.
It may be said that there are examples suggestive of late Paleolithic
tools, a few Mesolithic forms, and numerous early Neolithic types.
Comparisons are frequently made between these implements and those
from various European stone industries. This is misleading, however,
as the American examples must have been derived from eastern Asia
where the development of stone working was for the most part inde-
pendent of that in Europe. Such similarities to European types as
may occur have no chronological significance and should not be used
as criteria for dating New World material.
There has been considerable disagreement and much argument over
the date of the arrival of the first immigrants from Asia.’ This situa-
tion may be attributed to the basing of conclusions on such differing
factors as the characteristics of the archeological material, the faunal
assemblages, the nature of the human skeletal remains, and the geologic
evidence. The latter as a rule is considered as being the most accept-
able, and dates based on it are now regarded by many as substantially
correct. Without going into the problems of glacial variations and
synchronization, varve counts, fossil pollens, and related subjects, it
will suffice to say that from these sources the ages of various phenomena
have been determined. The opening of the corridor east of the
Rockies, making migration southward from Alaska possible, has been
placed at 15,000 to 20,000 years ago. There appears to have been a
similar opening some 20,000 years earlier, but it is generally considered
as being too ancient to have played a part in human activities. The
termination of the last pluvial in the North American Southwest,
which is important in the study of a number of the manifestations, has
been dated at approximately 10,000 years ago. The Lindenmeier site
in northern Colorado is dated at from 10,000 to 25,000 with the state-
ment that it may have been nearer the 25,000 mark (Bryan and Ray,
1940), although other authorities consider the 10,000 figure as more
nearly correct (Sayles and Antevs, 1941, p. 41, note 29). The Black
Water Draw, between Clovis and Portales, N. Mex., has been dated
12,000 to 18,000 (Antevs, 1935a). The oldest level of the Cochise is
NEW WORLD PALEO-INDIAN—ROBERTS 499
put at a little over 10,000 (Sayles and Antevs, 1941). Gypsum Cave
in Nevada is given as 8,500 (Harrington, 1933). Ventana Cave has
not been dated as yet, but on the basis of similarities with other re-
mains it is probable that the oldest level there would approximate the
10,000 figure. Sandia Cave seems to fall into the same category as
the Lindenmeier or Black Water Draw.
No date has been suggested thus far for the human footprints and
bison tracks in Nicaragua. The Confins man was considered as hav-
ing lived a “few thousands of years ago” (Walter, Cathoud, and
Mattos, 1937), and the remains in Patagonia have been estimated at
3,000 to 5,400 (Bird, 1938b). An interesting question has developed
in regard to the latter, however, since that estimate was made. If
the subsidence of Laguna Blanca took place at the time of the retreat
of the last ice sheet in that area, the cultural horizons antedating
that occurrence would be much older. On the basis of a correlation
between the varves in the Northern and Southern Hemispheres the
time of the recession in the lake has been placed at about 10,000 years
ago. Inasmuch as the deposits at Palli Aike Cave have suggested
that the entire period of human occupation of the area may be twice
as long as the interval since the retreat of the ice, plus a span of
unknown duration when the debris was collecting on the original floor
and the layer of volcanic ash was accumulating, something over
20,000 years would be indicated.* In view of the situation in North
America this appears to be too long a period, but it raises the question
as to whether the remains may not be older than originally postu-
lated. The problem is directly involved in that of the synchronization
of ice ages in the north of the Northern Hemisphere with those in
other parts of the world, and as there are various indications that
simultaneous ice ages for the whole earth are not necessarily admis-
sable it is possible the Patagonian phenomena were actually some-
what later. There is no way of telling at this stage of the investiga-
tions how long it took the migrants to travel from northern North
America to the tip of South America. Some think of it as a slow
and laborious process, others believe that it may have been relatively
rapid. If 15,000 be taken as the maximum for North America and
10,000 for the southern end of South America, the Nicaraguan mani-
festations might be considered as approximating 12,000 to 13,000—
providing, of course, they represent the earliest north-to-south drift—
and Punin and Confins between 11,000 and 12,000. The North
American data apparently have a better foundation than those from
South America, and there is a possibility that the dates just postu-
4Information received from Dr. Bird in a letter written after the appearance of the
original article in Acta Americana. On the basis of present evidence Dr. Bird believes
such an age far too great.
430 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
lated for the latter are too great, although the former estimate for
Patagonia may be somewhat too conservative.
There is nothing in the human physical types that would conflict
with a 10,000- to 15,000-year age for the first occupation of the New
World. In Upper Paleolithic times throughout the Near East and
Europe, as well as in eastern Asia, several races of modern-type man
were in existence at an earlier stage than any thus far suggested for
the New World. Consequently: the fact that the earliest arrivals did
not differ greatly from modern Indians and have shown only sporadic
primitive features should not be regarded as denying the possibility
for such an age. However, the situation is somewhat different archeo-
logically. Thus far there is scant information about the late Paleo-
lithic in eastern Asia beyond the fact that there was such a stage and
that certain types of implements correlate with it. There is little that
compares with these older forms in the New World material, but there
is much that is like the Neolithic artifacts of the period just preceding
the appearance of pottery and various polished-stone tools. Because
of this some argue, with considerable logic (Spinden, 1937), that the
New World complexes could not possibly have originated prior to
5,000 to 6,000 years ago, while others are willing to concede a maxi-
mum of 8,000. The answer probably is to be found in Asia in the
transition stage between the end of the Paleolithic and the appearance
of the full Neolithic. At present there is no available information on
that cultural phase, and until the results of future investigations are
at hand there can be no decision in the matter. This seeming discrep-
ancy between geologic dates and archeological evidence emphasizes
the need for further study of the problem.
Thus far there is not much basis for correlations between the older
types of remains with those of later Indian groups. With the excep-
tion of the Cochise, and possibly also of some of the manifestations
in the Abilene district, all the early complexes were followed by a
definite break. They are separated from subsequent assemblages by
a sterile layer. The later manifestations, however, in all cases appear
to continue through a series of cultural horizons down to historic
times. The break in continuity is unmistakable in the Folsom sites,
Gypsum Cave, Sandia Cave, Ventana Cave, and numerous other North
American occurrences not described in the present article, and also at
Fell’s Cave in South America. In view of this and because of the rela-
tionship between some of the Ventana Cave and Cochise materials, as
well as the difference between the oldest Cochise and other early com-
plexes, it is possible that the bottom level of the Cochise may have been
placed one stage too early and that it actually belongs in the phase
beginning just after the interval which is characterized, in all other
locations where such remains are found, by an absence of traces of
NEW WORLD PALEO-INDIAN—ROBERTS 431
human occupation. In fact some geologist think that the sand-gravel
layer in which the Cochise material occurs may be a redeposition
rather than an original flood plain and that the archeological speci-
mens are later than the animal bones and gravel would indicate. If
the widespread evidence for such a hiatus is correct, some explanation
should be found for the break in continuity and for the possibility that
the earliest migrants, like the animals they hunted, became extinct.
On the other hand, if the first occupation was followed by uninter-
rupted inhabitation, some good reason for the sterile stratum in so
many sites should be forthcoming. One postulation has been that the
break merely was in the plains and the southwestern area, where the
increasing temperatures and progressive desiccation following the
onset of the postglacial produced unfavorable conditions and forced
the people on eastward and southward to other regions where they
continued to live. Eventually, after an amelioration of the climate
in their former habitat and an influx of new migrants who found it
again suitable for occupation, their descendants came in contact with
some of the later peoples and there was an intermingling that is chron-
icled in the sporadic appearance of older physical types in recent
groups. This is a logical explanation, but thus far the preponderance
of archeological evidence is against it.

EASTER ISLAND?
By ALFRED M&TRAUxX
Assistant Director, Institute of Social Anthropology, Smithsonian Institution
[With 4 plates]
A treeless volcanic rock, scarcely 13 miles long and 7 miles wide,
slowly being eaten away by the waves and lost in the great emptiness
of the Pacific Ocean—2,000 miles off the coast of Chile and 1,500 miles
from the nearest Polynesian archipelago—this is Easter Island, the
most isolated spot ever inhabited by man. Today it supports a mere
handful of natives, mostly half-castes, and many of them lepers.
These 450 people, now under Chilean rule, are the only descendants
of the men who created there one of the most original civilizations
that have left a trace behind. Yet they have all but forgotten their
past.
For two centuries, the name of the island has been almost synony-
mous with mystery. In the world of ethnologists it occupies a place
much like that of isles of fancy in children’s imaginations.
The sense of mystery which still surrounds this lonely rock was
first aroused on Easter Sunday, 1722, when the Dutch Admiral Rog-
geveen, in command of three frigates cruising about the Pacific in
search of the fabulous Davis Land, saw the dome-shaped peaks of its
volcanoes jutting above the horizon. From the decks of their ships his
sailors, as they drew nearer, could discern all along the cliffs of this
unknown shore an army of gigantic statues, which completely over-
shadowed a small band of naked and noisy savages on the beach
below. The visit of the Dutch discoverers did not last long, but they
carried back to Europe the strange tale of a solitary, desolate island
guarded by colossal stone images, far too heavy and impressive to
have been carved and erected by the few primitive people they found
living there.
Later in the eighteenth century, and afterward, Easter Island was
visited in succession by several other great navigators: Cook, La
Pérouse, Kotzebue, Beechey. They, too, saw with amazement the
stone monsters, measured them, and even sketched them. To their

minds also, the contrast between the monuments, indicative of a
flourishing and skillful population, and the desolation they found
about them was a peculiar enigma. They spoke of cataclysms, of
volcanic eruptions, that might have changed the course of the island’s
history, but these were pure guesses based on superficial observation.
In the first half of the nineteenth century, a different group of visi-
tors appeared. These were the whalers, most of them enterprising
New Englanders in pursuit of business and adventure in the South
Seas. A few echoes of their experiences come to us in indirect ways.
Thus we know that the captain of one of these ships kidnapped several
men who afterward escaped and tried to swim back to their island
although they were 3 days out. It is not surprising that relations
between the whalers and the natives were far from cordial. Too often
the ships’ officers resorted to impressing the islanders into their serv-
ice. Such incidents explain the hostility shown to some European
navigators between 1820 and 1830 when they attempted to land. But
these brief visits of Yankee sailors were not without benefit to the
study of Easter Island. Thanks to their collecting instinct, numerous
precious specimens of its early art have been well preserved in the Pea-
body Museum at Cambridge and the Peabody Museum at Salem. In
Cambridge, besides various wood and stone carvings, there are two
images brought from the island, made of bark stuffed with bulrushes,
which represent a branch of its artistic tradition otherwise entirely
unknown. They are covered with painted designs that reproduce,
with fine and precise workmanship, the elaborate patterns used in
tattooing up to a hundred years ago. In this respect the old Easter
Islanders rivaled the achievements of the Marquesans.
In 1859 a frightful disaster befell the islanders when Peruvian
blackbirders attacked the island and kidnapped the king, a large
number of the nobles and priests, and many hundred commoners, all
of whom were carried off to the guano islands of Peru to work as
slaves. Most of the people died within a short time. When at last the
few survivors were repatriated by a French ship, they spread among
the remaining islanders the smallpox and tuberculosis contracted in
Peru. Thus within a few years most of the native population and
with them the vital links with the past were wantonly destroyed.
The mystery of Easter Island became still deeper when, in 1864,
the first Christian missionaries (members of the French Order of the
Sacred Heart) arrived and tried to obtain from the natives details
about the origin of the statues, and the methods that had been used to
transport them—since many of them had obviously been moved from
the place where the stone was quarried. Their answers to questions
of this kind were unilluminating and showed that they had only a
vague tradition of what had happened before their time. Their ig-
norance, combined with the state of primitive poverty into which they
EASTER ISLAND—MBETRAUX 437
had fallen, again emphasized their enigmatic relation to the lost civi-
lization, of which the statues and great stone mausoleums as well as
other finely wrought remains of the past were mute evidence.
Then scientists began to study Easter Island. At what time and
by what manner of men, they asked, were these images made, with
their colossal bulk, their empty eyes and scornful expressions? Was
the island the remnant of a sunken continent? Had it been inhabited
by a powerful earlier race which had died out, or been destroyed and
displaced by more warlike conquerors? Had eruptions of the vol-
canoes exterminated the skilled craftsmen, the sculptors, and the archi-
tects, leaving only a small group of people too discouraged and weak
to continue the work of their forefathers? These are among the
questions that still puzzle students.
The statues symbolize the mystery of the island and have made it
famous. Yet their paradoxical presence on this speck of land in
the midst of the Pacific is perhaps less difficult to understand than
are the wooden tablets covered with small incised designs that were
collected from the natives in the second half of the last century. The
tablets raised the fascinating question whether their makers used on
them a kind of hieroglyphic script which might some day be de-
ciphered and would unveil the secret of its past. But all attempts to
decipher them, with the help of intelligent natives, failed.
A few years ago the study of the tablets took an unexpected turn.
A Hungarian linguist, Guillaume de Hevesy, published a long list
of Easter Island hieroglyphs which, it was claimed, presented very
striking analogies with the symbols of a newly discovered script found
in the ruins of a civilization, 5,000 years old, in the Indus Valley at
Mohenjo-daro and Harappa. There, coetaneous with the Sumerian
civilization, flourished large and opulent cities inhabited by people
whose name and affiliations are totally unknown to us. They were
wiped out probably at the time of the Aryan, and their existence re-
mained unsuspected until the great excavations of Sir John Marshall.
The Mohenjo-daro people have left a great many inscriptions on seals
which have so far resisted any attempt at decipherment. If it could
be shown that the two scripts were related, new light might be thrown
on the obscure past of the whole Pacific area.
The problem thus posed was of such significance for an under-
standing of the early history of man that the French Government in
association with the Belgian Government decided to organize an
expedition to Easter Island to try to read its riddle. The leader of
the expedition was a French archeologist, Charles Watelin, who,
unfortunately, died in Tierra del Fuego. I was then asked to carry
on the research, in association with the Belgian archeologist, Dr. Henry
Lavachery.
438 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
We saw Easter Island for the first time on a rainy day in winter.
It was also my first sight of a Polynesian island. I did not expect,
of course, to find the classic coconut palms and hibiscus, for I knew
that the island was without trees or shrubs, but I certainly had not
imagined that this outpost of the sunny islands in the South Seas
would remind me, as it did at once, of the coasts of Sweden and
Norway. When the cruiser on which we had made the voyage
anchored off Hangaroa, the only modern village on the island,
memories of Scandinavia came even more vividly into my mind as I
examined through my field glasses the frame houses of the natives,
which are of a type common in northern Europe. The capital of the
legendary Easter Island looked, for all the world, like a humble fisher-
men’s hamlet seen in a fog on the Baltic.
I shall never forget that first day when we were anchored just off
the little harbor. Gusts of wind drove long rollers against the shore
with such force that they broke amid spouts of spray with a deep
pounding. In front of the sandy cove, the waves piled up over a bar
that, it seemed, nobody could cross. The natives gathered on the
beach did not appear very eager to meet us, but the aranga, the cries
which announce any important event, had sounded in the village,
and from everywhere, on all the paths leading to the sea, we could
see men on horseback coming at full speed. Near the boathouses a
palaver was held, and on the outcome of that everything depended.
The commander of the cruiser had decided that on no condition would
he put us and our 90 boxes of equipment ashore. Our only hope for
an immediate and safe landing lay with the natives.
Suddenly we saw them rush to the boathouses, drag three canoes
toward the sea, jump into them and disappear in the surf. We held
our breath, expecting the canoes to capsize in their attempt to cross
the bar. But after a short time, one, two, then all three surged up
from the wall of water and headed toward our ship. The men were
received with cheers, a well-deserved tribute to their courage and
skill.
When the canoes reached our ship we saw that they were full of
natives wearing the most surprising disguises. The majority were
dressed in old uniforms of the Chilean navy. In one canoe there
were, it appeared, lieutenants, admirals, surgeons, and engineers. A
few had also put on feather headdresses, similar to those in which
their ancestors had received Captain Cook, but they wore them merely
as an advertisement of the native wares of all kinds which they wished
to trade for shirts and sailors’ caps.
Each time I find myself using the word “natives” for the modern
inhabitants of Easter Island, I have a hesitant feeling, just as hesi-
tant as on that day when I first saw their faces over the railing. I
eS
EASTER ISLAND—METRAUX 439
could not decide whether these men were a heterogeneous crowd of
European beachcombers or real Polynesians, the sons of the sea
rovers who had colonized the island. That European blood flowed in
their veins, there was no doubt. Some of the men who came aboard
and tried to sell their curios looked decidedly French; others might
almost have had brothers or cousins in Hamburg or in London. Yet
there was something exotic in all of them and traces of old Polynesian
descent could be seen in their black, wavy hair, in the strange, viva-
cious dark eyes, in the high foreheads. These first Easter Islanders
whom I met impressed me as of mixed race. Later, genealogical
investigations showed that only a third of the present inhabitants
could claim descent from a pure Polynesian ancestry—and the claims
were not always well attested.
There is one misconception about these people which should be
dispelled. It has been stated over and over again that the modern
Easter Islanders are a degenerate population and that they can have
nothing in common with the people who carved the statues and
inscribed the tablets. This is not true. They appeared to me in
many ways to be highly gifted.
During the 6 months I spent on the island, I found myself com-
pelled to admire their ingenuity and their remarkable talent for
assimilation. No European village has given me the impression of
more intelligent adaptation to a changing world. This capacity is
doubtless responsible, in part, for the passing of the old culture.
Though the most isolated people in the world, the Easter Islanders
are constantly on the lookout for new ideas, new fashions—and also
new vices. Their extraordinary faculty for exploiting any weakness
or interest in their visitors has had some amusing results. For ex-
ample, a few years after the missionaries came to the island, the
natives started to speculate on the antiquities and on the mysterious
past of their little country. Finding that foreigners were interested
in the small wooden images of emaciated figures which had been one
of their forefathers’ greatest artistic achievements, they proceeded
to produce crude imitations by the hundreds. The modern craftsmen
are without illusion as to the perfection of their work, but they excuse
themselves by saying: “Why should we bother about beauty and
finish when our patrons don’t discriminate between good and bad
images and we get in exchange the soap and clothes we want?”
Thanks to this commercial instinct, several of their old industries
have been kept alive.
One of their greatest and most profitable activities is palming off
on amateur archeologists rough stones alleged to be ancient artifacts
or well-made imitations of them. The very day of my landing a
native cynically proposed to cooperate with me in faking old imple-
619830—45——-29
440 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
ments and works of art. His idea was that since I had books and
photographs showing the designs and he had the manual skill we
might form an ideal, not to say a profitable, partnership. I must
confess that on several occasions the islanders’ skillful imitations
completely deceived me, and I thus acquired a beautiful collection
of ancient stone hooks that I only gradually realized were modern
copies.
This continued practice of the traditional arts has a certain his-
torical bearing. It suggests that there has never been a complete
breach in Easter Island civilization and that the present natives,
however mixed in blood they may be, are, nevertheless, the successors
in direct line of the unknown men who carved the old wooden images
that are nowadays prized specimens in our museums.
Unfortunately, this is not the only old custom which has survived.
From the time when the Dutch discovered the island to the present,
its people have had the reputation of being the cleverest thieves in
the South Seas, and quite rightly. This complaint is repeated in all
the accounts of the early navigators, and many of the dramatic inci-
dents on the beach of Hangaroa have arisen from the natives’ brazen
contempt for the sanctity of private property. Only the sensitive
and elegant French explorer La Pérouse adopted the policy of laugh-
ing at such pilfering, and paid no further attention to it. He and
his men were amused by the attitude of the native women who helped
their mates pick pockets by distracting the attention of innocent
victims through entreaties and “ludicrous gestures.”
The natives of our day are just as thievish as their forefathers, and
this wayward disposition is the cause of endless troubles for the Eng-
lish company which has leased the island from the Chilean Govern-
ment for sheep raising. To prevent constant stealing of the sheep
the company put barbed wire across the island in an attempt to
force the people to remain within the bounds of their village. But
such drastic measures were of little avail, and in the year I spent there
3,000 sheep disappeared. Though the culprits are known to the whole
community, family loyalty protects them and makes investigation
useless,
Otherwise the natives are law-abiding and peaceful; there are very
few records of murder or bloody violence among them. The only
criminal we heard of was one of our guides, who, ironically enough,
proved to be about the only honest man on the island.
The people live as they did in the past, on the produce of their
fields. Taros, sweetpotatoes, yams, bananas, and sugarcane grow
abundantly on the fertile volcanic soil. The only wants they can-
not supply themselves are for manufactured goods such as soap. And
they like especially to get foreign clothing. In this matter, the men
————EeEeEeEeEeEeEeEeEeEeEeEeEeEeEeEeEeEeEeEeEe——e——eeaeEeEEee
EASTER ISLAND—METRAUX 441
do well’ for themselves by barter with the white sailors who visit the
island, but the women cannot be so provided for. They complain
bitterly of the difficulty they have in satisfying their coquettish taste.
For an anthropologist, the material on Easter Island is rather
scant. The old culture has nearly gone. No Westerner ever saw it
while it was still functioning. The data on the past, which can be
gathered, are limited to statements or tales which a few people have
heard from fathers or grandfathers. Nevertheless, I was surprised
to find a relatively rich folklore, which helped me to understand many
aspects of the ancient civilization. Both legends and anecdotes stress
cannibalism, which seems to have haunted the imagination of the
Easter Islanders before the arrival of Christianity.
Those who expect to find in these traditions any evidence for the
existence of a civilization previous to that of the Polynesians will be
sadly disappointed. There is not a single feature of the Easter Island
lore that does not point toward Polynesian origin. The language
itself is pure Polynesian, and no words now in use hint of a legacy
from any other linguistic stock.
These are the main facts to bear in mind as we turn to the problem
posed by the mysterious gigantic statues and the inscribed tablets.
But before we go into it, we must first consider what is to be said of
the theory that the island is a peak of a sunken continent, since upon
this assumption the classic interpretation of its mysteries has for a
long time rested. There is no scientific evidence that Easter Island
“is the wreckage of such a sunken continent—Lemuria or Atlantis.
It is plainly a typical volcanic island of recent origin, formed by a
series of eruptions originating on the floor of the ocean. Soundings
have revealed a depth of 1,770 fathoms 20 miles from its coast.
Moreover, when the island was settled by Polynesian migrants it does
not seem to have been much more extensive than it is now. Its coasts
are subjected to continual erosion from the waves, and it is true that
during the last decades a few of the monuments which once stood on
the top of a high cliff have been precipitated into the sea. But since
the ancient sanctuaries were erected along the shore, if the erosion
had been very great, all of them would have been washed away by
now. There has also been a question about a great road which, it is
said, ran to the shore of the island and continued under water, sug-
gesting that the shore was once much farther out. The famous French
writer, Pierre Loti, was, if I am not mistaken, the first to mention this
“triumphal avenue,” which he thought would lead to the heart of the
mystery. On a simple statement of this traveling poet visions of
submerged glory have been based, and many good minds have allowed
their imaginations to follow the submarine road down to enchanted
palaces. The truth is that no such road exists. What Loti took for
442 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
a paved highway is seen on close examination to be only a bed of
lava that in its flow reached the sea.
Other writers, abandoning the hypothesis of the sunken continent,
have advanced the view that Easter Island is the center of an archi-
pelago which vanished beneath the waves in a great cataclysm not
so many centuries ago. They suggest further that the inhabitants of
this supposed string of islands had used Easter Island asa burial place
for their dead. According to this surmise, the dream Land of Davis
would have been among the many islands that were submerged. But
no geological facts can be found to support this theory either. We
know, too, that the sanctuaries of Easter Island continued to be used
as burial places by the islanders as recently as 70 years ago. Ruins
of old villages near the monuments are added evidence that this
speck of land was inhabited by the living in former times as it is
today, and that it could not have been merely a mausoleum.
However, there remains the baffling fact that such a diminutive
island is covered with great statues, some of them 30 or 40 feet high and
weighing many tons. Despite my skepticism about the elaborate
theories offered in explanation of this miraculous flowering of sculp-
ture, I must confess that I, too, like all previous travelers to the island,
was overwhelmed by a feeling of astonishment and awe when I first
saw them.
There are few spectacles in the world more impressive than the
sight of the statue quarry on the slopes of Ranoraraku. The place is
indeed sinister. Imagine a half-crumbled volcano, a black shore line,
and huge cliffs which rise up from the sea with smooth green pastures
above them. Guarding the quarry, near the volcano, is an army of
giant stone figures scattered in the most picturesque disorder. Most
of them still stand out boldly. Successive landslides have partially
covered others, so that only their heads emerge from the ground, like
those of a cursed race buried alive in quicksand. Behind the rows
of the erect statues, along the slopes of the volcano, there are 150
figures still in the process of being born. Wherever one looks in the
quarry, one sees half-finished sculpture. Ledges of the mountain
have been given human shape. Caves have been opened in which
statues rest like those on medieval sepulchers in the crypt of some
great cathedral. Hardly a single surface has been left uncarved by
the artists in their frenzy to exploit the soft tufa of the mountain.
There is something weird in the sight of this deserted workshop with
the dead giants all about. At every step, one stumbles over discarded
stone hammers. It is as if the quarry had been abandoned on the
eve of some holiday, and the workers were expecting on the day after
to return and resume their tasks; indeed, in several cases, only a few
more blows would have been needed to cut the statues finally free
from the rock of the slope.
EASTER ISLAND—METRAUX 443
In my opinion, the seemingly sudden interruption of work in the
quarry is the most puzzling problem presented by Easter Island. Such
an abrupt stoppage in the sculptors’ activity suggests some unfore-
seen catastrophe, some extraordinary event which upset the entire
life of the place. The natives have always had the idea that magic
was at the bottom of the trouble whatever it was. There is a legend
among them that an old sorceress, forgotten perhaps at a feast, may
in her rage have put a curse on the quarry which frightened the work-
ers forever away.
If we reject this fabulous story, we have no explanation of the
phenomenon for which there is any basis however slight. Was there
possibly some surprise attack by a hostile group on the island in
which all the skilled stone carvers were killed? Was there an attack
from chance invaders? Were the natives suddenly overwhelmed by
a violent epidemic, or did something about their first contact with
white men cause them to lay down their tools once for all? We do not
know the answer, and I doubt if we shall ever have any light on it.
Whatever the truth about the end of their work, it appears that
the last of the stone carvers were under the spell of a megalomaniac
dream. Some of the unfinished statues are of enormous size, one of
them 60 feet tall. Others are to be found in places out of which it
seems impossible that they could ever have been taken. Perhaps their
sculptors never intended to move these isolated giants.
There are two types of Easter Island statues—those which still stand
in the crater or at the foot of the volcano Ranoraraku, and those which
once surmounted the ahwu or burial places. Though they are of the
same stone and of the same general style, there are differences which
are worth stressing.
A word must be said about the burial places, which were situated at
frequent intervals all along the shore in a line that encircled the
island. Most of them were huge stone structures of a peculiar
plan developed from the primitive cairn. In these large mausoleums,
the crude heap of stones has evolved into a real monument through
the use of a retaining wall. This wall, which formed a facade always
facing seaward, was built of slabs or regular blocks of stone carefully
fitted together into beautiful, smooth surfaces. Behind this is a level
platform, and then a gradual slope backward, filled in with coarse
rubble. The central portion of the facade juts out, like the apron
of a stage, and on the top of this projecting part of the platform
stood a row of statues with their faces turned inland. In the long
slope leading up to this sacred place the dead were buried.
The figures of the mausoleums or sanctuaries were in the nature of
huge busts, the head being disproportionately large in relation to what
appears of the body. The back of the head goes straight up from the
shoulders and, with the vertical lines of the ears, gives the head a
444. ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
flattened appearance. The eyebrows are well marked and overlap the
elliptical cavities which represent the sockets of the eyes. The nose is
long, the tip slightly upturned and the nostrils expanded. The thin
lips are pursed with what seems a scornful expression. The arms,
slightly flexed, cling to the bust with the hands joined over the ab-
domen, below which the figure is cut off.
The other sculptures on the island—the lonely images on the plain
and those that guard the slope of the volcano Ranoraraku—have the
same features except that there are no sockets for the eyes. This part
of the face, as in some modernistic sculpture, is defined only by the
ridge of the eyebrows and by the flat plane of the cheeks below. The
lower part of these statues tapers to an enormous peg, which was
sunk into the soil.
The function of the ahu images can be surmised from analogies with
the rest of Polynesia. The old Marquesans, close relatives and perhaps
forebears of the Easter Islanders, adorned their stone platforms with
statues which represented their ancestors. Among all the natives of
central and marginal Polynesia, there is the same tendency to give
human form to ancestral gods presiding over the sacred places. In
the sanctuaries of central Polynesia stood huge slabs that were erected
in the same position as the Easter Island statues. These slabs were
receptacles for the souls of the ancestral gods, who entered them when
they were called by the priests. The Easter Island statues are merely
a more realistic development of this idea, favored by the existence of
easily carved tufa deposits. Their sculptors elaborated rather than
originated a tradition.
Everywhere on the island statues are to be found: on top of volcanic
hills, along cliffs, and in places which seem almost inaccessible. Their
mass must have made their transportation difficult. As a matter of
fact, no one has yet explained how some of them were hauled from the
quarry and then erected on the platforms on the opposite side of the
island.
Of course, there are many other instances of people with rudimentary
equipment moving objects of great size—for instance, the dolmens and
menhirs of Europe. As the statues that the Easter Islanders
erected on their sanctuaries were of the native tufa, they were not ex-
ceedingly heavy for their bulk. Their weight ranges from 5 to 8 tons;
only one weighs as much as 20 tons. But because the rock from which
they were carved is soft, it must have been necessary to take innumer-
able precautions not to mar or break them in transit. This would
have been easy if abundant supplies of wood had been accessible,
but, except for a few bushes, the island seems always to have
lacked wood. Good material for making ropes was apparently also
lacking. The only thing they could have been made from is paper
EASTER ISLAND—MBETRAUX 445
mulberry, which the natives grew in special stone-enclosed plots. Per-
haps the wood necessary for making sledges on which the statues might
have been hauled was lumber that floated ashore. This is frequently
mentioned in ancient tales. If native timber or driftwood was available
in the old days, the difficulties of transportation would not have been
overwhelming. We know that other Polynesians transported objects
quite as heavy as the Easter Island images. For instance in the
Marquesas, slabs weighing as much as 10 tons were hauled along the
slopes of the mountains. The famous doorway, or trilithon, of Tonga,
which is one of the marvels of the world, has a lintel weighing 30 tons.
But when the Easter Islanders of today are asked about the means by
which the statues were transported, they only say: “King Tuu-ko-ihu,
the great magician, used to move them with the words of his mouth.”
Other questions have arisen about the Easter Island carvings. How,
for instance, did the people get the manpower for such large enter-
prises, which would have been impossible, it seems, if the population
were as Small as it istoday? The answer is that before the Europeans
arrived, the island had ten times as many inhabitants as it now has—4
or 5 thousand would be a conservative estimate. We know this from
data given by its first European visitors and the early missionaries.
Again, are these statues as old as has been said? Certain writers have
dated them as far back as 1000 B. C. There are even some who think
that they might have been in existence 10,000 yearsago. But the weight
of general evidence is against these views. Although their material is
a relatively soft stone, they still retain sharp outlines, and the ham-
mer marks are still noticeable on them. As the winds blow with re-
lentless force over the island, and rains are both frequent and violent,
if the carving had been done thousands of years ago, it could not be
in such good condition as it is today. Tradition seems to indicate that
the Polynesian ancestors of the present inhabitants came to the island
and settled it in the twelfth and thirteenth centuries A. D. All things
considered, I do not think the statues can be more than five or six
centuries old. But no definite date can be set for them.
The figures of stone that stood so high above the shores of Easter
Island, and in such striking formation that it is no wonder they amazed
the old navigators, have attracted more attention than the other myste-
rious objects to which I have already referred—the wooden tablets
with rows of strange signs incised on them. But these curious pieces
of wood have also given rise to much speculation. They were bought
from the natives by the missionaries in the early days of their work,
and ever since they have been thought to contain a real script which,
if it could be read, would prove a key to the island’s mysteries.
The first white man to discover the tablets was Monseigneur Jaussen,
French Bishop of Tahiti, in 1866. As he was looking at a piece of
446 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
wood, wrapped around with strands of hair, which a missionary had
brought from Easter Island as a gift from the natives to the head of
their new church, he was puzzled by the rows of small designs he
noticed on it. These he took to be hieroglyphs, and his view has been
shared by all the later students of the problem. The so-called “hiero-
glyphs,” cut in the wood with a shark’s tooth, are realistic or conven-
tionalized drawings of various subjects, including apparently geo-
metrical figures. Many of them represent men, animals, plants, and
other familiar forms reduced to their essential features with no unnec-
essary detail to blur the image. They run up and down the tablets
in rows so arranged that when the reader arrives at the bottom of
one row, he has to turn the tablet upside down to see the designs of
the next one in a normal position. These images, or characters, are
among the masterpieces of primitive graphic art that have come down
to us. They are outlined with an exquisite grace. The symbols are
uniform in style suggesting an established and highly developed
aesthetic tradition.
Unfortunately, the discovery of this remarkable work was not fol-
lowed up by scientific inquiries at a time when they might have borne
fruit. When, finally, in 1914 Mrs. Katherine Routledge, the distin-
guished English anthropologist, tried to obtain a key to its meaning
from the last native who had been trained in the old chanters’ school,
it was already too late. He died of leprosy a few days after his first
interview with her. The modern natives know nothing of the matter.
They tell merely vague tales of the tablets, saying that they are magical
objects which have the power to cause death.
The supposed substance of the rows of designs on some of the tablets
was dictated in the Easter Island dialect to Jaussen by a native named
Metoro. But when Metoro’s words were translated it appeared that
they were only a simple description of the designs, not their actual
content, as had been hoped.
Other attempts at interpretation have been undertaken but with
even less success. The most serious was that of an American naval
officer, W. J. Thomson. In 1886 he tried to obtain the text of what
was inscribed on the tablets from an elderly native. This man un-
doubtedly had some knowledge of the characters, but he had become
a good Christian and was afraid of jeopardizing his chances in another
world by touching the tablets or even looking at their pagan symbols.
In order to resist the temptation, he ran away and hid in a cave, where
Thomson finally captured him. There he was “stimulated” by flattery
and a few drinks to what was thought to be a revelation of these secrets
of the past. At any rate, he began to chant old Polynesian hymns,
which he said were the texts of the tablets. Thomson and his col-
leagues noticed, however, that their informant was paying no atten-
EASTER ISLAND—METRAUX 447
tion to the rows of designs as he chanted and did not repeat his words
when the same tablet was put into his hands a second time. He was,
therefore, thought to be a fraud and was dismissed.
As I have already said, a definite clue to the enigma of this so-called
“seript” seemed at last to have been discovered 7 years ago, when Mr.
de Hevesy pointed out a series of analogies between some of these
Easter Island designs and those of an old Asiatic script found on stone
and clay seals in the ruins of two forgotten cities, Mohenjo-daro and
Harappa, in the valley of the Indus. Now, archeologists agree in
thinking that the civilization of the Indus region dates from about
3000 B. C. Its people were an unknown race that knew how to build
planned cities with a complicated sewerage system. The script they
used is still undeciphered, but hypotheses about it have been ad-
vanced which, if substantiated, would make it one of the earliest
known forms of man’s writing. Some Orientalists see striking anal-
ogies between this Mohenjo-daro script and the early Chinese
hieroglyphs.
Although the relationship between Easter Island “script” and that
of the Indus has been accepted widely as a demonstrated fact, I can-
not help being skeptical for several reasons. The Indus civilization,
contemporaneous with that of Sumeria and Egypt, was extinct by
2000 B.C. Easter Island culture died out only 80 years ago. Roughly
15,000 miles of land and sea separate the Indus Valley from the island.
Between them lie India, Indonesia, and enormous wastes of water.
In other respects Mohenjo-daro and Easter Island have nothing in
common: the arts of the Indus, like weaving, pottery, and metal
working, were unknown to the remote islanders. The proud city
dwellers of Mohenjo-daro would have looked down upon the half-
naked people who lived in thatched huts, and indulged in cannibalism.
How could two such different and widely separated peoples have shared
the same form of writing?
In order to answer this question, Mr. de Hevesy advanced the theory
that the Easter Island tablets are many centuries, if not millenniums,
old and were brought to Easter Island by the first immigrants. Here
the evidence that remains is against him. The wood of the best and
largest Easter Island tablet is that of a European oar. Besides, if
Hevesy’s theory were to be accepted we should have to make the diffi-
cult assumption that the Easter Islanders kept their script unchanged
for more than 5,000 years. A careful analysis of the tablets and the
Indus script has not borne out this theory. True, some of the signs in
the Indus script have striking analogies with those of Easter Island.
I am, nevertheless, still more impressed by the divergencies, and by
the doubtfulness of parallels based only on a few cases which take no
account of many variants of the same design.
448 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Moreover, there is little question, I believe, that the designs on the
tablets were created by natives of Easter Island. It would be difficult
to explain on any other assumption the presence among them of so
many figures of animals belonging to the local fauna and of objects
that are found, as far as is known, in its culture only. Mr. de Hevesy
interpreted certain of the Easter Island symbols as representations of
monkeys and elephants, but for these suggestions of India’s jungle
life he drew on his imagination.
In the hope of throwing some light on the mystery, I applied to sev-
eral tablets an analytical method. I counted their symbols and studied
their combinations to find out whether they might constitute an actual
script. If the symbols represented sounds, the same signs would have
been combined in the same order whenever a word was repeated.
But this seldom happens. The same combinations of the same sym-
bols recur in only a very few cases. The individual designs are re-
peated over and over again but apparently in haphazard order. No
clue to a script.came from this study.
If we might assume that the tablets contain an actual script, the
question would arise whether it were pictographic or ideographic.
To answer this there are not enough different symbols. Most of them
are variants of about a hundred fundamental designs. On certain
tablets the same signs form a high percentage of the total.
Assuming that the Easter Island tablets contained a script, I thought
it likely for a long time that this was based on the same principle
as the designs inscribed on birchbark by the Ojibway Indians, who
record charms by means of figures which sometimes remind us of
the Easter Island symbols. From the images drawn on bark, the In-
dian shaman reads a text which, to his mind, they represent. The
Cuna Indians of Panama still use the same primitive form of writing.
But one thing made me suspicious of such an interpretation. The
Easter Island tablets are pieces of wood of various odd shapes which
are always covered with designs from one end to the other And on both
sides. If their contents corresponded to a script text, this would mean
that the artist always knew in advance just the size and shape of the
piece of wood his chant would fill. As this seemed highly improbable,
I was obliged to abandon this entire hypothesis and seek for some
better clue to the mystery.
I found it in a link that has been kept between the tablets and the
oral traditions, songs, and prayers of the Easter Islanders. The very
word that the natives use for the tablets puts us on the right track.
They are called kohau rongorongo, which means literally “orator
staff”—that is, the stick, sometimes decorated with carved symbols,
sometimes not—which a speaker holds in his hands while making a
public address or reciting a piece of traditional lore, as if to give added
significance to his words. The rongorongo were professional chanters
EASTER ISLAND—METRAUX 449
who formed a society, which existed not only on Easter Island but
also on other Polynesian islands. In childhood they were taught in
special schools to memorize and to recite the lore of their tribe.
Everywhere in Polynesia the chanters use such an “orator staff.”
Sometimes, as in New Zealand, the staffs are provided with notches,
which are supposed to help in reciting genealogical tables. In the
Marquesas, the chanters held, while chanting, a bundle made of string
wound about with knotted ends hanging down, which was thought of
as containing the substance of the chant though the connection be-
tween the words and the contents of the bundle was loose. The bun-
dles symbolized the chants and were in consequence of paramount
importance. They were solemnly given to the young people after
they had been initiated into the lore of their ancestors.
These facts, I concluded, give us the best clue in the problem of
the Easter Island tablets. To its chanters as to the chanters of other
islands, the “orator staffs” were the accessories and the symbols of
their function. Originally, the designs on the staffs or tablets might
have been mnemonic, but later on they lost their exact significance
in the minds of the natives and were looked upon merely as simple
ornaments or magic symbols. It may be added that even now we
can observe on Easter Island a slight relation that has been preserved
between design and chant. The natives are in the habit of chanting
when they make string figures or cat’s cradles. This interpretation
of the tablets may not contain the whole truth about them. I offer
it rather as the hypothesis which best fits the facts available today,
and which harmonizes also with what we know of an underlying
tendency in Polynesian civilization.
But these are not all the questions that have been raised by Easter
Island. Some observers have found in the well-carved and well-
fitted stones of its sanctuaries likenesses and relations to the ancient
remains in Peru, and to account for them have said that there must
have been intercourse between these two parts of the world at some
period of history. But close study has revealed that between the
Peruvian and the island ruins the resemblances do not go beyond
the general fact of an exact fitting of the stones. The plan and the
structure of the Peruvian buildings are entirely different. In Peru
the walls are all of carved stone blocks, whereas in Easter Island
they consist of slabs set on edge outside with rubble behind. The
only conspicuous architectural achievement of the Easter Islanders
was to select the slabs and to dress their corners so that no gap would
appear on the surface and impair the general appearance. This they
could naturally have learned to do without crossing the Pacific in
frail canoes and making the long journey inland to the site of the
wonderful ruins in Peru. Moreover, these are certainly far older than
the Easter Island sanctuaries. Thus it seems clear that we must
450 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
give up hope that the remains on Easter Island will help to solve
the problems of early American civilizations.
The result of 3 years’ work on the island culture pursued at the
Bishop Museum in Honolulu, with which I have been associated,
shows that this Ultima Thule was discovered and settled by Poly-
nesians, who arrived in a fleet of double canoes sometime, roughly,
between the middle of the twelfth century A. D. and the end of the
thirteenth. The time of the discovery and settlement can be estab-
lished approximately from the lists of chiefs that have come to us.
These the early missionaries took down from the dictation of the
natives. I was permitted to copy another one from a list which my
native informant had compiled himself. Many errors have, of course,
slipped into these records, but a comparative study of them shows that
Faster Island has been ruled by about 25 or 30 chiefs since the founder
of the dynasty, Hotu-matua, and his people first came to its shores.
Allowing 25 years for each ruler’s reign—the usual method of meas-
uring time in Polynesian annals—we find that this must have hap-
pened very close to the twelfth or thirteenth century. From other
sources, we know also that this was a period of great sea expeditions,
and that the settling of New Zealand and of many other islands in
the Pacific occurred in what seems to have been a heroic age of
ancient Polynesia.
Curiously enough, the oral tradition of the migration to Easter
Island has been preserved remarkably well even down to the present.
While I was there, I was told in great detail many more or less legend-
ary incidents of the voyage eastward of Hotu-matua and his associate,
the noble Tuuko-ihu. These stories with their core of history were the
glorious sagas of the first emigrants to this little lost world.
At about the same time, the Tahitians, Maori, and Marquesans had
a culture which was still undefined but was very similar in the different
groups. In the course of the succeeding centuries, over each of these
island areas a civilization developed along original lines, though still
retaining the common background. The Kaster Island culture belongs
to this purely Polynesian type. The ancestors of the present popula-
tion merely improved upon the legacy they received.
Where then did the Easter-Islanders come from? Since they are
Polynesians in race, language, and culture, the problem of their origin
coincides with that of the Polynesians as a whole and is as yet unsolved.
That the Polynesians came from Asia is beyond doubt. India, Assam,
and Indo-China have been variously given as the cradle of these sea-
faring tribes, but sufficient evidence to validate these theories is still
lacking. Within the Polynesian world the Easter Islanders offer
many analogies with the Maori of New Zealand, the people of Manga-
reva and those of the Marquesas. Actually the resemblances between
Easter Island culture and that of the Marquesas are very striking. It
EASTER ISLAND—METRAUX 451
is possible that the Easter Islanders were among the early Polynesian
emigrants who spread from central Polynesia toward the east, occupy-
ing the Tuamotus, Mangareva, and the Marquesas. Very likely after
a sojourn in the Marquesas some again sailed eastward and discovered
Easter Island. At the time they left the Marquesas their culture, of
course, had not yet developed the specific pattern which characterized
it when the Europeans landed there in the eighteenth century.
The genealogies of Mangareva, the nearest Polynesian island to
Faster Island, date back to the twelfth century, but traditional history
mentions early immigrants who settled on these islands and then left
for other countries, leading a restless life. Similar traditions exist
among the Marquesans. Hotu-matua, the discoverer of Easter Island,
and his followers may well have represented a defeated tribe or a
junior branch of the Marquesas or Mangareva.
What remains today of their work is evidence of the beauty and
greatness of their isolated civilization, revealing the vigor and audacity
of these Polynesians who spread over what seem once to have been
the happiest islands on earth.

BRAIN RHYTHMS?
By E. D. Aprian, O. M., F. R. S.
University of Cambridge
In 1929 Prof. Hans Berger, of the Psychiatric Institute at Jena,
published the results of some work on which he had been engaged for
many years. He had set out to record the electric currents devel-
oped in the human brain, and had shown that if metal electrodes were
fixed to the scalp, it was possible to detect a regular oscillation of elec-
trical ‘potential which was not due to muscles or skin glands or any
other source outside the skull, and could only have come from the
nerve cells of the cerebral cortex. The oscillation had a frequency
of 9-10 a second. It only appeared when the subject was at rest with
attention relaxed and eyes closed; but it obviously represented some
kind of continuous activity in the brain covering a fairly large area.
What he discovered was then quite unexpected. It has made us revise
many of our ideas about the brain and has brought us a little nearer
to understanding what goes on in it.
The oscillation, Berger’s a rhythm, represents a very small change
of potential, about 50 microvolts, and a very small ebb and flow of
current in the cerebral cortex. There is nothing unexpected in the
fact that brain cells develop small currents when they are active, for
all active cells do so. The unexpected thing is the regularity of the
rhythm.. It is true that if it were not so regular it might never have
been detected, but the regularity means that large numbers of brain
cells must be working in unison at the same rate. We should have
expected something much more complex and variable—activity vary-
ing from moment to moment and from place to place—and not the uni-
form pulsation shown in a typical record of the electroencephalogram.
We should have expected this because the brain is a great sheet of
nerve cells and interlacing nerve fibers, and its working must depend
on the spatial distribution of activity in it. This is determined by
the particular pathways which must be taken by the incoming and out-
going messages, for the messages are all in the same form wherever
they come from and it is because they arrive in different regions that

we interpret one as sight and another as sound. We know, for exam-
ple, that if one looks at a bright cross, the initial event in the brain
will be the activation of a more or less cross-shaped area at the back
of the occipital lobe, and that if one hears a sound a pattern will be
reproduced in the temporal lobe corresponding to the areas of vibra-
tion in the cochlea. All the external events of which we are aware
are recorded as spatial and temporal patterns of excitation in the sense
organs. These patterns are reproduced in the brain with a good deal
of editing, omission of details and heightening of contrasts, and it is
from them that we reconstruct our external world.
Now the a rhythm of the electroencephalogram comes from large
areas in the occipital region and to some extent from the frontal area
as well. At first sight this seems to leave little room for all these
diverse patterns of electrical activity. But actually the regions where
the potential change is at a maximum are not those where the messages
from the sense organs are received in the brain, but are the neighboring
“silent” or “association” areas. Also, to make the rhythm appear, the

eyes must be closed and the attention relaxed, so that the brain is rela-
tively inactive, at least so far as vision is concerned. Thus the regular
wave sequence is derived from certain parts of the cerebral cortex
when these have little to do. The cells there are not concerned with
the incoming signals and so will be free to beat in unison, and if fairly
large areas are so beating our records from the head will show the «
waves and will not show the small local irregularities which are prob-
ably going on all the time so long as we are conscious.
The cells of the cortex might beat like this when they are left alone
because this is how they are made; because like heart muscle or cili-
ated cells they cannot remain alive and inactive; or the beat might be
imposed on them by rhythmically active cells in some other part of the
brain which can act as pacemaker to the association areas. Wherever
the pacemaking region may be, the important fact is that the rhythm
is much the same from one person to another. For clinical purposes,
therefore, an electroencephalographic recording can be used as an
index to show whether the brain is working normally or not, and for
this reason it has become an important technique of clinical neurology.
Apart, however, from the value of. these records as a means of diag-
BRAIN RHYTHMS—ADRIAN 455
nosis, there is the problem of their significance in relation to the
normal mechanism of the brain and of the mind. Do they tell us
anything about the neural accompaniment of perception and thought ?
The statement that one can record the electrical activity of the brain
through the skull raises the hope that one should be able to detect all
sorts of brain events connected with consciousness. The hope begins
to fade when it is realized that the main feature of our records is a
rhythm from nerve cells which are relatively inactive. But there is
something of interest to be learned from them. It is true that we
cannot yet record the detailed activities of different parts, but only
the gross changes when a whole area goes into action; yet these do give
us some novel information about the physical accompaniments of
thought and in particular about the process of attention.
To begin with, it seemed that the « rhythm was much less interesting.
It might have been merely a spontaneous beat of the nerve cells in
parts of the cortex, particularly those concerned with vision—a beat
developing whenever the cells were not stimulated by messages from
the eyes. Opening the eyes would break up such a rhythm in the
receiving area, because the visual pattern there would mean that dif-
ferent groups of nerve cells would be discharging at different frequen-
cies. Something of this kind.can certainly happen in the regions
where a message enters the cerebral cortex, for in records from the
exposed brain (in anesthetized animals) the arrival of a message in
the receiving area produces small, rapid waves in place of the slower
and larger « rhythm. But the a waves are not confined to the
receiving areas of the brain, and it can be shown that in fact the
presence or absence of messages from the eyes is not the essential
condition for the disappearance or return of the « rhythm.
As far as vision is concerned, what really determines the presence or
absence of these waves is not whether visual messages are or are not
coming into the brain, but whether we are or are not attending to
them—whether we are looking at anything. Man is a visually con-
trolled animal, and if our eyes are open there is usually something in
the visual field which catches our attention or some part of it. This is
not true for all mammals; the rat and the cat seem to rely more on
other senses and can be quite inattentive to sights. But with us the
only sure method of shutting out sights from the mind is to close the
eyes. Normally, therefore, opening the eyes means that we start look-
ing, or that we become attentive to the visual field. The « waves then
disappear, and they return when we close our eyes and cease looking.
But shutting the eyes does not cut out all light from the retina, and the
a rhythm appears in the brain however much or little light may be
falling on therclosed lids. Even in a pitch-black room, if we open our
eyes and start trying to see something, the rhythm goes, although open-
619830—45——30
456 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
ing the eyes cannot have altered the illumination of the retina. Sooner
or later, when we have given up the attempt to see, the waves will
return although the eyes are still open.
What matters, therefore, is not the excitation of the retina but the
turning of attention to the visual field or away from it. This can be
shown even more clearly in another way. In daylight and with the
eyes open, the attention can rarely be abstracted completely from
vision except for short periods; something keeps on “catching the eye”
and coming into the mind, even though we have most of our attention
fixed on other things, a sound or a smell, for example. The reason why
the visual field cannot be completely ignored is that the picture of it in
our brain has patterns and sequences which arouse interest by recalling
memories or starting some new train of activity. But if we can make
the visual field convey less meaning, it will cease to be so attractive
and our attention can leave it more easily. A simple way of securing
this is to wear spectacles which will throw everything out of focus.

Figure 2.—The a rhythm appears when the attention is transferred from vision
to hearing. The visual field has been made unattractive by +10 D spectacles.
During the middle section of the record the attention is concentrated on the
tick of a watch.
When this is done, although the eyes remain open, the a rhythm will
appear much more readily than when the visual field is in its proper
focus. With the field blurred, we have only to listen intently to a
sound and the « waves will begin, to cease again if we transfer our
attention back to vision. Here, too, there has been no change in the
illumination of the retina but only the shift of attention. It may be
noted that it is not only the intellectual interest of the field which holds
our attention. Any movement in it or any sudden change of illumi-
nation will do so; and there is a great variation in the ability of differ-
ent persons to detach the attention from vision, and in the same person
at different times.
All this shows that the « rhythm is an activity which appears in the
cerebral cortex when the attention is not directed to vision, and dis-
appears when it is. The mental act of looking somehow prevents the
a waves from developing in certain parts of the brain, parts which are
likely to be concerned in analyzing the visual pattern. The a rhythm
is therefore a rhythm of inattention, a positive activity which fills those
%
BRAIN RHYTHMS—ADRIAN 457
parts of the cortex which are for the moment unemployed. It is not
the basic rhythm of unstimulated nerve cells, and there must be some
kind of competition between the message from the eyes and from the
source of the a rhythm to decide which shall control the cortical areas.
To examine this competition in more detail, we must have some way
of recording the sensory activity of the brain as well as the a activity.
All the messages which reach the cortex will produce their own elec-
trical accompaniment, and this can be recorded well enough if elec-
trodes can be placed on the surface of the brain. But if we can get no
nearer than the scalp, the potential changes generated in any group
of nerve cells will usually be obscured by those of other groups nearby,
and the record will then show us nothing. Fortunately this difficulty
can be overcome, in part at least, by making all the cells work in unison.
This can be done, as far as vision is concerned, by making the field more
or less uniform and lighting it with a flickering light. The nerve cells
are then forced to work in unison at the frequency of the flicker, and
we can record their electrical activity through the skull up to fre-
quencies of about 30 a second. This gives us a method of tracing the
visual messages in the brain, for by means of the flicker rhythm they
can be made easy to recognize.
Provided that the flickering area is in the center of the visual field,
it need not subtend more than a few degrees at the eye to give a
potential oscillation at the same frequency in the occipital region, The
waves are more or less where one would expect them to be, in the right
occipital region if the left half of the field flickers, and vice versa. But
the flicker waves are not confined to the visual receiving area: they are
found also in the neighboring areas, those from which the « waves
come when the eyes are closed. The flicker area is not so large as the
« area, but on occasion as much as a quarter of the brain surface seems
to pulsate with the flicker rhythm. The retinal messages must then
have spread widely and impressed their rhythm on some of the asso-
ciation areas of the cortex.
Now if the eyes are open, the flicker will keep the visual attention
engaged and the « rhythm at bay. But if the eyes are closed and the
flickering light is thrown on the closed lids, the subject will be con-
scious of the flicker but the conditions will favor the « rhythm, since
closure of the eyes is usually coupled with the withdrawal of attention
from vision. In these conditions the two rhythms can be seen to com-
pete for the cortex, and sometimes to cooperate if their frequencies
allow of it. The flicker rate will sometimes appear in patches with
the a rate in between, and if a rapid flicker is turned on suddenly the
area of the brain giving the flicker rhythm may be large at first and
may then shrink rapidly, giving place to the « waves but persisting
longer in regions nearer the visual area. If the flicker is made equal
458 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
to or twice the a rate, we may find the two summing up to give very
large regular waves. Such a combined rhythm usually takes some time
to build up as the two sets of waves have to be synchronized, but there
is evidently an interaction between them and a tendency to remain
synchronized as long as their frequencies are not too far apart. These
wave effects vary from one subject to another and there are variations
according to mood, time of day, etc.; in general, the sleepier the subject
the more the « rhythm will predominate, and the brighter the flicker
the more persistent will be the flicker rhythm.
The interaction and interference of these rhythms shows how the
cortex, or certain parts of it, may be put at the disposal of our atten-
tion. If we decide to look, or if it is decided for us by something
“catching our eye,” a change occurs which prevents the « rhythm
from occupying the regions surrounding the visual receiving area.

from the a rhythm to the flicker rhythm when the eyes are opened and the sub-
ject looks at a screen lit by a flickering light. The rate of flicker (17 a second)
is shown by the photoelectric cell record below.
If we can turn our whole attention to a watch ticking, the « rhythm
comes back. What brings this change about?
The evidence is still rather scanty. It is likely that the whole of
the cerebral cortex is concerned, in that it is the balance of activity
in every part which determines where the attention will turn and
how long it will be held in one field; but the executive act, the direc-
tion of the attention to the particular field, is probably carried out
by a relatively small central region in the neighborhood of the thala-
mus and near the main incoming pathways. It is from there that
the a rhythm seems to be controlled, and it is at least probable that it
is the sudden disturbance of this region which causes the loss of
consciousness after a blow on the head. This central directing
region must act on information received from the cortex, for it will
be all the memories and associations stirred up by a stimulus
which will determine its interest, and these are presumably not
aroused until the message has reached the cortex. But the central
region must balance up the conflicting claims of different stimuli and
BRAIN RHYTHMS—ADRIAN 459
we
must then decide which should have the main share of the attention,
its function resembling that of a central university committee which
has to decide which branch of learning should be supported by the
next benefaction.
The visual stimuli always get the lion’s share. If they are at all
interesting, the central region will suppress the « rhythm over the
occipital area, so that the visual pattern has a considerable part of the
cortex set free for its analysis. When the visual pattern ceases to be
interesting and the attention is directed to sounds or other sensory
messages, the occipital lobe is not turned over to those but is filled
again with the a rhythm. This is shown very clearly in records in
which the visual waves are made recognizable by the use of a flicker-
ing light, and if the flicker happens to be at twice the « rate a partial
diversion of attention will be enough to give the large compound
waves at the a frequency.
Apparently the occipital part of the brain is used to analyze sights,
and sights only. What parts deal with the patterns aroused by
sound and touch we cannot yet say. The areas seem too small to be
easily detected, and must certainly be much smaller than the areas
which deal with vision. On the other hand, a concentrated mental
effort may sometimes abolish the « rhythm although the eyes remain
shut. Presumably in this case the whole of the « area may be turned
over to nonvisual activities.
There are still many gaps in the evidence, but there is much to
support the view here put forward, namely, that there is a deep-
seated part of the brain which contains the mechanism by which
attention is directed one way or the other, and that the a rhythm is
under the control of this region, if it is not directly produced by it.
If this is so, it is not difficult to understand that abnormalities in the
« rhythm are often associated with abnormal kinds of behavior. The
most valuable application of the electroencephalogram in medicine
is in the localizing of diseased regions and tumors of the brain by the
change in the character of the waves. Another is its use in detect-
ing the sudden explosive discharges of the nerve cells which occur in
the brains of epileptics. But quite apart from such obvious disorder
of the brain cells, the electroencephalogram may show an « rhythm
which is definitely abnormal, irregular, faster or slower than usual
or with odd-shaped waves, and in a significant proportion of the
subjects who give such records there are abnormalities in the mental
or emotional sphere which may be a serious handicap. There are, of
course, many factors besides the constitution of the brain which de-
termine whether we react like our fellows or not, but the brain is a
not unimportant factor and the electroencephalogram seems to offer a
means of assessing some of its deviations from the normal. It re-
460 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
mains to be seen whether its use for this purpose will have much
practical value: at present the most that can be said is that if we
had to appoint someone to a responsible post and had an unlimited
field of candidates, it would be safer to exclude the 5 percent whose
electroencephalogram showed the most unusual features.
That is a very long way from saying that the electroencephalogram
can tell us how the subject will think and act. In fact the information
which it gives relates to a very limited field. But the limitation
arises mainly from the fact that we can only record the gross effects
and not the detailed patterns in the brain. With present methods
the skull and the scalp are too much in the way, and we need some
new physical method to read through them. We need the “patent
double million magnifying gas microscopes of hextra power” with
which Sam Weller thought he might be able to see through “a flight
o’ stairs and a deal door.” In these days we may look with some
confidence to the physicists to produce such an instrument, for it is
just the sort of thing they can do; but until it is available we have to
confess, with Sam Weller, that ‘our wision’s limited.”
THE DEVELOPMENT OF PENICILLIN IN MEDICINE!
By H. W. Ftorry and EH. CHain
Ozford University
Discovery of the chemotherapeutic effects of penicillin has excited
widespread comment in the lay as well as the medical press. A first-
hand account of how this substance was introduced into medicine
may, therefore, be of interest.
The phenomenon of the inhibition of the growth of one micro-
organism by another has been known for more than 60 years, for
Pasteur and Joubert in 1877 noted that anthrax bacilli were pre-
vented from growing when certain other organisms were also present
in the culture medium. To them is credited the first suggestion of
using this antagonistic property of bacteria for curative purposes.
Since this fundamental observation, many examples of the same
phenomenon—called microbial antagonism—have been recorded.
In many cases the inhibitory effect of one microbial species on another
is due to metabolic products formed by the antagonist. These prod-
ucts have recently been termed “antibiotics.”
The earliest attempt to introduce antibiotics into medicine was
made by Emmerich and Low in 1898. They extracted an impure
material, which they termed “pyocyanase,” from old culture filtrates
of Pseudomonas pyocyanea and showed that it had the property of
causing death, or lysis, of some of the bacteria which can cause disease
in man. They recommended pyocyanase for the local treatment of
various infectious diseases, but it did not come into general use,
although apparently it was on sale in Germany, until at least 1936.
The only other serious attempt to utilize antibacterial products for
combating infection in man has been the employment of gramicidin,
obtained from cultures of Bacillus brevis. This powerful substance
was discovered by Dubos in 1939, and although it is far too toxic to
inject into the blood stream it can be used for application locally to
infected wounds.
In 1929 Alexander Fleming noticed that colonies of staphylococci
growing onan agar plate were undergoing lysis in the neighborhood
of a contaminating mold colony. Most bacteriologists would have

passed this over, but Fleming, an acute observer with a special inter-
est in antiseptics, subcultured the mold for further investigation.
From its descendants all the penicillin in the world was produced
until recently.
The mold was identified as Penicilliwm notatum. Fleming culti-
vated it in a liquid medium, peptone broth, and found that it pro-
duced in the broth a substance capable of inhibiting the growth of
many dangerous germs, even when diluted 800 times. The active
substance he named penicillin. He noted that broth containing
penicillin was not more toxic when injected into rabbits and mice
than pure broth and that it did not appear to be harmful to the white
cells of the blood.
As a result of this, he suggested that penicillin might be a good
antiseptic to apply to septic wounds, and indeed a few cases were
so treated. He concluded that it certainly appeared to be superior
to dressings containing potent chemicals. The observations, how-
ever, were not carried further, though Clutterbuck, Lovell, and Rais-
trick made an attempt to extract the active material. As a result
of their work they concluded that penicillin was extremely unstable,
and they did not pursue the matter.
In the succeeding years no further interest seems to have been taken
in its chemical properties or its possible application to medicine,
though Fleming continued to use the crude culture medium in the
laboratory as a means of suppressing the growth of certain kinds of
bacteria in mixed cultures.
In 1929 one of the present authors, H. W. Florey, started work on
the antibacterial substance lysozyme—another discovery of Fleming’s.
This substance was first discovered in egg white but is widely distrib-
uted in nature. It has the power of dissolving or killing certain spe-
cies of air bacteria, though it has, unfortunately, no effect against
bacteria causing disease in man.
The work on lysozyme was carried on until its purification (by
Roberts in 1936) and the elucidation of its mode of action as a carbo-
hydrate-splitting enzyme (Meyer and associates, 1936; Epstein and
Chain, 1940). During the later part of this work, in 1938, the present
writers decided to undertake a systematic investigation of the anti-
bacterial substances produced by bacteria and molds, about whose
chemical and biologic properties little was known.
Although the reports suggested that penicillin was an unstable sub-
stance, it was among the first chosen for investigation, since it seemed
likely to be of considerable biochemical and biologic interest. In
particular, it was active against many organisms causing the most
destructive lesions in man, including staphylococcus. Fleming,
Clutterbuck, et al., reported that under suitable conditions penicillin
PENICILLIN—FLOREY AND CHAIN 463
activity was retained in the culture medium for some weeks. This
suggested that, if appropriate conditions could be found, the extrac-
tion of penicillin from the culture medium and its purification would
be possible.
For work of the scope envisaged it was apparent that results would
be obtained most quickly by a team of workers, and we have been par-
ticularly fortunate in our collaborators. Dr. N. G. Heatley devised
a simple and quick quantitative assay method which has proved in-
valuable in the elaboration of purification processes for penicillin and
in similar investigations on other antibiotics. He also designed and
constructed the first large-scale laboratory plant for. growing the
mold and extracting penicillin. Dr. A. G. Sanders later devised
and built alternative apparatus for the extraction of penicillin on a
larger scale. Prof. A. D. Gardner of the Department of Path-
ology, Oxford, collaborated throughout on the bacteriologic aspects
of the work. The biologic investigations were carried out by H. W.
Florey in collaboration with Dr. M. A. Jennings of the School of
Pathology, Oxford; the chemical and biochemical investigations by
E. Chain in collaboration with Dr. E. P. Abraham. The therapeutic
trials on man were conducted first by Dr. C. M. Fletcher and later
by Dr. M. E. Florey, with the help of many physicians and surgeons.
It was established that penicillin was an acid of low molecular
weight, which was stable in water. In an acid medium, it was found
to be quickly destroyed. It could, however, be extracted by various
organic solvents, such as ether, chloroform and amyl acetate, from
acid solution and was found to be quite stable in these solvents.
From the organic solvents it could be re-extracted into water by
the addition of the right amount of alkali. Little loss of antibac-
terial activity occurred during these operations provided they were
carried out quickly and the solutions were kept cold. This transfer of
penicillin between solvents and water has become the basis of all the
extraction processes used on a large scale by commercial firms.
By repeating the process several times and varying the solvents, a
considerable purification and concentration of penicillin is achieved.
On drying the final solution from the frozen state a preparation of
penicillin is obtained in the form of a yellow powder which keeps its
antibacterial activity unchanged for a long time. Though chemically
still very impure—these preparations contain only about 10 to 20
percent of pure penicillin—the antibacterial power is great. They
contain about 100-200 Oxford penicillin units per milligram, which
means that when diluted from 1 part in 5,000,000 to 1 part in 10,000,-
000 they prevent the growth of staphylococci. Preparations of this
degree of purity can be used for all clinical purposes.
464 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Further purification presented a harder problem, since penicillin
is unstable toward many reagents normally used for purification pur-
poses. It is unstable in dilute acids and alkalis and is destroyed by
many metals, such as copper, cadmium, zinc, and mercury, and by
primary alcohols and oxidizing agents such as potassium permanga-
nate. This severely limited the selection of methods for purification,
but penicillin preparations which are almost pure have now been
obtained.
The purest material obtained in Oxford has an activity of about
1,000 units per milligram, corresponding to an inhibitory power
against the staphylococcus of about 1 part in 50,000,000. Pure crystal-
line sodium penicillin has been obtained. It contains about 1,670 Ox-
ford units per milligram. By international agreement the Interna-
tional Unit is the specific penicillin activity contained in 0.6
microgram of pure penicillin II (or G). The unique feature of
penicillin, when compared with other antibacterial substances, is
that it combines this astonishingly high antibacterial activity with
a very low toxicity. An amount several hundred times greater than
the therapeutic dose can be injected intravenously—into mice—with-
out any noticeable toxic effect.
This lack of toxicity is also observed with less pure preparations,
and it may indeed be counted as extremely fortunate that none of the
numerous contaminating substances causes harmful effects, even when
the dose of penicillin is large—far beyond that necessary for thera-
peutic purposes. For this reason it is unnecessary to subject peni-
cillin to the elaborate and difficult purification processes before it can
be used for clinical purposes.
After the low toxicity of penicillin had been demonstrated on mice,
a more extended study of its biologic properties was undertaken. It
was shown that a concentration at least a hundred times greater than
that necessary to stop the growth of sensitive bacteria was harmless to
the white cells of the blood and to tissue cells grown in glass vessels.
The very low toxicity of penicillin to the white cells of the blood was
of particular importance, as these cells play an important part in the
defense of the body against invading bacteria, which they have the
power to ingest and destroy.
Further research has shown clearly that when bacteria are put in
nutrient media in which they can divide, then penicillin will kill them.
If they are in such a condition that they cannot divide, then penicillin
does not kill them.
It was further shown that penicillin is readily absorbed from an
intramuscular or subcutaneous injection and from the small intestine.
Once absorbed in sufficient quantity, a simple test demonstrates that
it is present in the circulating blood. Unfortunately it cannot be
given by mouth, because the acid of the stomach would destroy it
PENICILLIN—-FLOREY AND CHAIN 465
before it reached the intestine. It does not pass from the blood into
the cerebrospinal fluid. Penicillin was shown to be rapidly excreted
in the urine, the bile, and to some extent in the saliva of animals. In
man also, excretion in the urine is very rapid, and this explains why
the doses have to be not only large but frequent. To keep a high con-
centration of penicillin in the blood is like filling a bathtub with the
plug out.
Another important observation was that the antibacterial action of
penicillin is not diminished in the presence of blood, pus, and tissue
constituents. This is in sharp contrast to the sulfonamide group of
drugs, whose activity is much lower when pus is present, and which
therefore have relatively little effect in suppuration.
The disease-producing bacteria which are affected by penicillin
make an impressive list. Many of them are sensitive to just as high a
dilution as the staphylococcus. Some are present in nearly every war
- wound, so that the interest of the armed forces in penicillin is readily
understood. This list is by no means complete. There have been
some additions to the list of sensitive organisms, the most important
of which—the 7’reponema pallidum—is that causing syphilis. This
means that syphilis becomes one of the diseases which can be treated
by penicillin.
Bacteria affected by penicillin
Sensitive :
Streptococcus (childbirth fever and many cases of serious sepsis).
Staphylococcus (boils, carbuncles, and serious infections of bone and other
organs).
Pneumococcus (pneumonia).
Anthrax bacillus.
Diphtheria bacillus.
Actinomyces (“woody tongue” of cattle and sometimes human disease).
Tetanus bacillus.
Bacilli of gas gangrene.
Gonococcus (gonorrhea).
Meningococcus (spotted fever).
Partially sensitive:
Typhoid bacillus.
Gaertner’s bacillus (food poisoning).
Vibrio El Tor (cholera-like disease).
Insensitive :
Tubercle bacillus.
Plague bacillus.
Cholera bacillus.
Brucella (undulant fever).
Colon bacillus and related organisms.
By all these methods penicillin was shown in the laboratory to be
an extremely powerful antibacterial agent with low toxicity. The
proof that it had chemotherapeutic properties, that is to say, that it
would cure disease in living creatures, was also first supplied in the
laboratory by what are known as “mouse protection tests.” Mice were
466 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
infected with bacteria which would certainly cause their death unless
some successful treatment could be given.
Streptococcus, staphylococcus and Clostridium septicum—a gas gan-
grene producer—were all used on a group of mice, and in each case
adequate doses of penicillin gave complete protection without any
toxic effect on the animals. A new chemotherapeutic drug had been
discovered.
The whole of the work en penicillin has been dominated by lack
of material. The mold produces very small amounts of the active sub-
stance, and it is a formidable job to grow it on a large enough scale.
In addition, the penicillin may be lost if the bacteria universally
present in the air contaminate the culture, for they produce a ferment
which destroys penicillin. A man is 3,000 times larger than a mouse,
and many months elapsed between the trial on mice and the first
injection in a man, while we struggled in the laboratory to produce
enough material.
The first injection of a small quantity of crude penicillin into man
showed that something was present which caused a rise of temperature.
Fortunately, this pyrogenic substance was an impurity and not the
penicillin itself, and further chemical purification removed it.
In the first two patients ever treated the amount of penicillin re-
quired was underestimated, and though improvement occurred, the dis-
ease was not cured, and there was no more material with which to
proceed. However, these two patients gave a good indication of the
amount required.
It has been possible to find out the dosage and method of administra-
tion, and with this knowledge it has proved possible to produce striking
results,on even the most serious cases of disease due to staphylococci
and other organisms.
This early work in Britain has now been fully confirmed in the
United States, and there seems little reason to doubt that penicillin,
with the further developmental work which is being undertaken every-
where, will fill an important place in medicine for the treatment of
many infections. We are only at the beginning of its exploitation;
further progress demands greatly increased supplies. Though no
doubt a great deal will be produced from the mold, it is to be hoped
that chemical progress will be such that penicillin, and even better
substances than penicillin, may be produced in real abundance by
synthetic processes.’
When plentiful supplies are available it should be possible to treat
those diseases which can be controlled by penicillin at the earliest
possible moment instead, as is so often the case now, of using the
drug as a last resort. When this may be done, an enormous amount
of temporary and permanent disability, and even death, may be
avoided.

RECENT ADVANCES IN ANESTHESIA?
By JOHN C. KRANTz, JR.
Department of Pharmacology, School of Medicine,
University of Maryland, Baltimore, Md.
INTRODUCTION
“Nothing in the whole realm of human effort has ever contributed so much to
human comfort as the discovery of modern anesthesia.”
Pain and discomfort are the arch enemies of man. To escape them
and effectually combat them, he has ransacked the entire earth to find
drugs to bring him a surcease of pain. During the middle of the
sixteenth century Ambroise Paré operated without anesthesia, except
for the administration of French wines, which would produce an
alcoholic stupor. Only 120 years have passed since Ephraim Mc-
Dowell removed an ovarian cyst from Mrs. Jane Crawford in Dan-
ville, Ky., without any anesthetic agent. She was then 47 years old
and lived to see her seventy-eighth birthday. It is difficult for man
today to appreciate the excruciating pain suffered by surgical patients
in the preanesthetic days and, further, no one can with certainty esti-
mate the impediment to surgical progress that the absence of
anesthesia produced.
NITROUS OXIDE
Joseph Priestley, the discoverer of oxygen, prepared the first gen-
erally accepted anesthetic. Priestley was a Unitarian minister in
Birmingham, England. In the congregation of this brilliant scien-
tist-clergyman were three illustrious men: James Watt, who discov-
ered the power of steam and holds the admiration of men in all walks
of life; Erasmus Darwin, brilliant scientist and skilled clinician
whose grandson, Charles, established a new order in biology; and
William Withering, “Flower of English Physicians,” discoverer of
the use of the purple foxglove in edema of cardiac origin. In the year
1773, Joseph Priestley made nitrous oxide. To him it was a new
chemical compound, a gas whose physical properties should be inves-
tigated. Priestley was unconcerned with its biological effects and died
in Northumberland County, Pennsylvania, not knowing that nitrous
oxide would confer a blessing of inestimable magnitude upon man.
A quarter of a century passed. Sir Humphry Davy, brilliant Eng-
lish chemist and physicist, made “Priestley’s gas.” It was then desig-
nated in chemical reports as ‘‘dephlogisticated nitrous gas.” Davy

inhaled nitrous oxide and observed a period of great exhilaration
with an increase in pulse rate. In a letter to one of his friends he
wrote: “I danced around my laboratory ikea madman.” But further
than this Davy observed that continued inhalation of the gas would
produce insensibility to pain. In fact, Davy anesthetized certain of
his friends to unconsciousness with nitrous oxide. On Jtuly 3, 1798,
Mr. Wedgewood called on Davy and he used nitrous oxide on him.
He recorded in great detail his experiences, which read, in most re-
spects, like a patient’s account of losing consciousness under nitrous
oxide. Davy suggested the use of nitrous oxide in medicine, but
nothing was done about it.
The scene shifted to America. In Hartford, Conn., on December
10, 1844, G. Q. Colton was delivering a lecture on popular science.
Among the experiments performed by Colton was the apparent hyp-
notism of certain members of the audience, presumably by means of
his gesticulations. Meanwhile one of Colton’s associates engulfed the
individual in nitrous oxide. This made effective the hypnotic art of
Colton. That same afternoon, a dentist whose name was Horace Wells
was in the audience. He saw one of the people swoon, fall and hit his
leg violently against a chair, without apparent sensation of pain.
Through his scintillating intellect flashed the era of painless dentistry.
The next day Wells persuaded one of his dental colleagues, Dr. Riggs,
to extract one of his teeth, while under the influence of “laughing
gas.” Wells did not whimper. The first step in man’s redemption
from pain had been taken. Wells did not succeed in establishing
the widespread use of his new anesthetic agent. In Boston, where he
endeavored to employ it, the gas bag failed most inopportunely, and
Wells was hissed out of the room as a mountebank and charlatan.
When death came prematurely to Wells, he did not realize what a
tremendous and far-reaching influence his observations would have
upon the comfort and even the destiny of the race.
This present decade, therefore, marks 100 years of use of nitrous
oxide as a general anesthetic. During this period its popularity has
waxed and waned, and during the last two decades the gas has defi-
nitely established itself for the smooth induction of ether-oxygen
anesthesia.
Nitrous oxide is a colorless, odorless gas which is alleged to possess
a sweet taste. The gas supports combustion only after the disinte-
gration of the molecule into oxygen and nitrogen. Seeds cannot ger-
minate or plants grow in an atmosphere of nitrous oxide. Nitrous
oxide is very soluble in water, from two to three volumes of nitrous
oxide dissolve in one volume of water. It is, however, like other gen-
eral anesthetics, more soluble in oil than it is in water. Blood will
dissolve a large volume of the gas. The gas does not combine with the
hemoglobin. Owing to its greater solubility in oil than in water,
ANESTHESIA—KRANTZ 469
the gas as it is carried by the blood to the central nervous system par-
titions itself out of the blood into the lipids of the central nervous
system producing narcosis. Induction is prompt, narcosis occurring
within 1 to 2 minutes. Anesthetists have set forth the following effects
from the inhalation of various concentrations of nitrous oxide:

Like many other volatile anesthetics, nitrous oxide enters the body
and leaves it unchanged. In other words, it is refractory to catabolism
by biological processes. Its anesthetic action according to modern
concepts is apparently due to the production of a reversible oxygen-
want in the central nervous system. By means of drugs, hypoxia of
the central nervous system can be produced by at least three
mechanisms.
1. Formation of carbonyl hemoglobin (carbon monoxide
poisoning).
2. Inactivation of the cytochrome oxidase in the cells (cyanide
poisoning).
3. Inactivation of the cytochrome reductase in the cells (narcosis-
nitrous oxide, ether, chloroform, etc.)
Substances used clinically as anesthetics affect the cells of the central
nervous system according to the third concept but, in addition, they
exhibit the property of affecting, first, the cells of the cerebral cortex;
second, those of the spinal centers; and, last, the cells of the vital
medullary centers.
Inexplosibility, safety, and availability are factors which give
nitrous oxide a place of pre-eminence among the volatile general
anesthetics.
ETHYL ETHER
Crawford W. Long of Georgia used ether as a general anesthetic
in 1842. He was familiar with some of the pharmacologic effects
of ether and in Jefferson County there were many “ether frolics”
which resembled modern parties of inebriates. He used ether also
to deaden pain in the reduction of fractures and on James W. Venable
to permit the surgical removal of a growth on the back of his neck.
Unfortunate it is indeed that Long did not publicize his observa-
tions for apparently the first paper published by Long on ether ap-
peared in 1849, 5 years after Wells’ work with nitrous oxide, and
3 years after Morton’s demonstration of the use of ether in Boston.
In Boston, a chemist named Jackson suggested the use of ether
to a dentist named W. T. G. Morton, who was a pupil of Horace
470 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
Wells. Morton persuaded Dr. J. C. Warren, son of Dr. J. M. Warren,
associated with General Putnam at the Battle of Bunker Hill,
to permit him to use ether on one of his patients. On October 16,
1846, in Massachusetts General Hospital, Morton began the admin-
istering of ether to Dr. Warren’s patient. From that operating room
reverberated that memorable statement which has echoed down
through the decades, “Dr. Warren, your patient is now ready.” Dr.
Warren commented that this was no humbug. Mr. Abbott, the patient,
was fast asleep. Ether had found its place.
Shortly after this, Oliver Wendell Holmes, in a letter to Morton,
conveyed the fact that he had assigned a generic name to ether and
all such agents. He commented on the importance of a proper selec-
tion of a name, for Holmes held that it would be on the lips of
every person of all races who in time to come would dwell on this
planet. He coined the word “anesthesia” from the Greek aoAnors,
perception, and the av negative, namely, without perception. Ethyl
ether is the most generally used of all volatile anesthetics. Its mode
of action is like that of nitrous oxide. It is not decomposed in the
body, but its presence in the cells of the central nervous system pro-
duces insensibility to pain and a hiatus in consciousness. Ether re-
quires 6 to 8 percent concentration in the inspired air to produce
anesthesia. During surgical anesthesia the concentration in the blood
is approximately 150 mg. percent. The blood pressure remains es-
sentially normal, respiration full and regular during ether anesthesia.
The relaxation of abdominal musculature is complete with ether.
The administration of the anesthetic agent in the circuit with oxygen
instead of air seems to reduce the incidence of postanesthetic nausea
and vomiting with ether. Postoperative abdominal distress and too
great a degree of volatility appear to be the principal drawbacks
to ethyl ether as an anesthetic.
Ether, when exposed to light and air, has a tendency to develop
peroxides. These are explosive and also serve as pulmonary irritants,
when ether containing them is employed as an anesthetic. The struc-
ture of ether peroxide, according to Wieland, is:
H H
cHy—c—o—0-b—cn,.
bx bn
Dihydroxydiethyl peroxide
The Pharmacopeia requires that ether used for anesthetic purposes
must be peroxide-free. The test is carried out as follows: “Shake 10
ce. of ether occasionally during 1 hr. with 1 cc. of a freshly prepared
aqueous solution of potassium iodide (1 in 10) in a 25-ce. glass-stop-
pered cylinder of colorless glass, protected from light: when viewed
|
ANESTHESIA—KRANTZ 471
transversely against a white background, no color is seen in either
liquid.”
CHLOROFORM
When the news of this important discovery of ether bridged the
Atlantic, James Simpson of Edinburgh, began an assiduous search for
substances as good as, or perhaps better than, the American ethyl
ether. It seems strange indeed that scientists in England did not pre-
cede those in America in the use of ether because Michael Faraday,
distinguished pupil of Sir Humphry Davy, was one of the first chem-
ists to produce ether. Simpson’s experiments were fraught with many
failures. Ether was better as a general anesthetic than most every
substance that he and his associates tried. One day, as he was fum-
bling through the papers on his desk, he found a vial of a colorless
liquid which had been sent to him by the German apothecary, Justus
von Liebig. And Simpson tried it—the liquid was chloroform. Sey-
eral times did he anesthetize himself and his associates, Keith and
Duncan, to unconsciousness with at least apparent impunity. It is
recorded that immediately Simpson recommended the use of chloro-
form to alleviate the pain of childbirth. To this the clergy of England
objected. They contended that this pain was a penalty pronounced
upon Eve for her transgression in the garden of Eden and in conse-
quence all subsequent generations of women should endure it with
patience and complacence. Simpson was a careful investigator, but
also was astute at repartee. To this criticism he very aptly replied,
“The Lord caused Adam to fall into a deep sleep before appropriating
his rib; out of which he created Eve.” God administered the first
anesthetic. Queen Victoria, that pioneer of English customs, broke
the spell of superstition by permitting Simpson’s chloroform to be
used in her seventh confinement.
Chloroform is about five times more potent than ether as an anes-
thetic. Itisalsomuch more toxic. The decline in the use of chloroform
in general anesthesia is due to its striking toxic action upon the heart
and liver. Ether does not exhibit this. Most deaths under chloroform
anesthesia occur in the induction stages. The mechanism of the acute
intoxication probably takes place in the following manner. Chloro-
form stimulates the vagus centrally and slows the heart. Through the
excitation of induction endogenous epinephrine stimulates the cardiac
accelerator, thus the simultaneous effect of stimulation and depression
of the heart rate produces fibrillation of the auricles and ventricles.
In addition, chloroform is carried from the alveolar air to the left
chambers of the heart in concentrations which are cardiotoxic. Before
this has been diluted by the general circulation, cardiac stoppage is
produced. The approximate mortality under chloroform anesthesia
is of the order of magnitude in 1 in 2,500; with ether, 1 in 10,000. It
619830—45——31
472 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
is of interest to note that the fluorine analogue of chloroform, namely
fluoroform, is neither anesthetic nor toxic.
ETHYLENE
After the discovery of chloroform there followed several barren
decades in the field of general anesthesia and at the turn of the century
the armamentarium of the anesthetist contained only nitrous oxide,
ether, and chloroform augmented in a small measure by ethyl] chloride,
Through the first two decades of the present century no substantial
gains were made. However, in 1922, ethylene was introduced by Luck-
hardt of the University of Chicago. It had been observed that traces
of ethylene caused the fading of flowers and this observation had come
to Luckhardt’s attention. He was curious about it. He wondered what
effect ethylene would have upon animal protoplasm. Systematically he
tested the gas on lower animals and observed its anesthetic effects.
Ascending in the scale of development, he observed that the anesthetic
properties held for monkeys and finally he permitted himself to be
anesthetized many times to unconsciousness and ethylene took its place
among the general anesthetics. Perhaps this discovery illustrates the
characteristics of a scientist, “one who has the simplicity to wonder, the
ability to question, the power to generalize and the capacity to apply.”
High concentrations of ethylene are required to produce anesthesia
(85 to 90 percent) and, to avoid hypoxia, the gas must be administered
with oxygen. The gas mixture is extraordinarily explosive, and many
tragic accidents have occurred owing to the explosion of the gas
through ignition by static electric sparks. Undoubtedly this has mili-
tated against the widespread use of the gas in many places.
AVERTIN
In 1927, Willstitter prepared a general anesthetic, tribromethanol,
marketed and employed as avertin, dissolved in amylene hydrate.
The principle involved in this discovery is based upon the theory of
narcosis announced by Meyer and Overton in 1900. Essentially this
theory holds that the greater the oil/water solubility is, the more
potent is its activity on the central nervous system. Alcohol
has anesthetic properties. The alcohols of the aliphatic series of hy-
drocarbons of higher molecular weight such as amyl and octyl alcohols
are less water soluble and more oil soluble, and their potencies as
anesthetic agents are greater than that of ethyl alcohol. In avertin,
three of the hydrogen atoms of the ethyl alcohol molecule having a
combined atomic weight of 3 have been replaced by three bromine
atoms, the sum of whose atomic weight is approximately 240. This
increase in molecular weight increases the oil/water coefficient and
simultaneously enhances the anesthetic potency of the compound.
Avertin is administered rectally. Its anesthetic index or safety mar-
ANESTHESIA—KRANTZ 473
gin is narrow, i. e., the anesthetic and fatal doses do not vary by a
great degree of magnitude. Therefore, most anesthetists prefer to
use the drug in amounts equal to three-quarters of its anesthetic dose
as a basal anesthetic and to complete the relaxation with nitrous oxide
or ether. The drug is contraindicated in patients suffering with
hepatic or kidney diseases. It is unfortunate that all of our data on
the efficacy and safety of tribromethanol are befogged by the fact
that it is employed dissolved in another anesthetic agent, namely,
amylene hydrate. Furthermore, avertin is a fixed anesthetic, and
threatened collapse under agents of this kind is much more difficult to
combat than it is under volatile anesthetics. Under the latter, removal
of the mask initiates the immediate course of removal of the agent
from the circulating blood. Obviously, when a fixed anesthetic agent
is used, this safety factor is unavailable.
DIVINYL OXIDE
It occurred to Chauncey Leake (1) of the University of California
in 1930 that it would be of great interest to prepare a hybrid molecule
between ethyl ether and ethylene, i. e., a molecule which contained the
essential features of the molecules of each of these anesthetics. Fol-
lowing this suggestion Major and Ruigh (2) prepared divinyl oxide,
“Vinethene.” The relation of these compounds to ethyl alcohol can
be seen from the formulas.

Ethylene Divinyl Oxide
Divinyl oxide is more powerful than ether. It is a liquid of very
low boiling point. With it, anesthesia is rapidly induced, but owing
to hepatic injury which may occur upon prolonged inhalation of this
anesthetic agent, its use is confined to operations of short duration.
One must not pass over the production of this new agent without pay-
ing due tribute to the fertility of the mind that conceived it. In its
conception a molecule was designed, synthesized, and anticipated
properties were later discovered to be inherent in it.
CYCLOPROPANE
In 1930 Lucas and Henderson (3) of the University of Toronto
announced the anesthetic properties of the hydrocarbon, cyclopropane.
The structure of cyclopropane is seen in the following formula:
CHa
H,c2_Scu;
474. ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
The gas is more potent than ethylene and hence permits the admix-
ture during anesthesia of a larger percentage of oxygen. Relaxation
of abdominal musculature is good during cyclopropane anesthesia.
During the decade of its use the gas is now established as an impor-
tant and dependable agent. Recognition of it in the United States
Pharmacopeia XII bespeaks its growing field of usefulness. A
brochure by Robbins (4) of Vanderbilt University on cyclopropane
reviews the entire field.
CYPROME ETHER
At the Medical School of the University of Maryland in 1939,
Krantz, Evans, Carr, and Forman (5) succeeded in developing a
chemical reaction for the convenient preparation of aliphatic cyclo-
propyl ethers. Four of these ethers have been prepared already, and
three of them have had preliminary trial. One of these agents is
cyclopropyl methyl ether known as cyprome ether; its structure can
be seen by the following formula:
CH;
H,c<Sc—o—CHs

The pharmacologic studies conducted in the University of Mary-
land show cyprome ether to be more potent than ethyl ether and pos-
sibly safer. Its boiling point is 10° C. higher than ethyl ether which
should be a distinct advantage for anesthesia in the Tropics. Black,
Shannon, and Krantz (6) in 1940 reported the first 25 human cases
of anesthesia with cyprome ether in “Anesthesiology.” ‘The compound
appears to be promising.

tors and are under study at the present time are:

PENTOTHAL SODIUM
Many years ago Frinkel prepared certain thiobarbituric acid com-
pounds. Based upon insufficient evidence upon a very limited number
of animals these compounds were discarded as not being worthy of
therapeutic merit. Within the past 5 years these compounds have been
reinvestigated and found to be very prompt-acting barbiturates, yet
ANESTHESIA—KRANTZ 475
the action is of very short duration. The one most extensively used in
this country is pentothal sodium. Structurally this compound is
pentobarbital in which the oxygen atom of the urea group has been
replaced by a sulfur atom.

(Nembutal sodium) (Pentothal sodium)
The widest use of this compound very recently has been in producing
anesthesias by intravenous injection for surgical procedures of short
duration. For this purpose 2 to 3 cc. of a 5-percent solution is injected
in about 15 seconds. The injection is then discontinued to permit
the complete effect to become manifest, which requires about 35 sec-
onds. If relaxation has not occurred, an additional 2 to 3 cc. may be
slowly injected.
The importance of pentothal sodium as a combat anesthetic cannot
be overestimated. The mortality statistics with pentothal sodium are
favorable and this agent appears to have warranted a permanent and
enviable position among the anesthetic agents.
SPINAL ANESTHESIA
The use of local anesthetic agents in the spinal fluid to produce
anesthesia dates back to the turn of the century. In the early days of
this form of anesthesia, the deaths were so numerous that the popu-
larity diminished. In more recent years, with more skillful technique
and more numerous new synthetic local anesthetic agents to select from,
this type of anesthesia has received a new impetus and is at present
enjoying much popularity.
When a local anesthetic is injected into the spinal fluid impulses over
all types of nerve fibers are blocked—sensory, motor, somatic, and
autonomic. The sensory block occurs in 6 to 8 minutes which is fol-
lowed by motor paralysis. The duration of the insensibility to pain
and the motor paralysis is a function of the character and the concen-
tration of the local anesthetic agent. Procaine hydrochloride in safe
concentrations produces an anesthesia of 1-hour duration. Tetracaine
hydrochloride, (pontocaine) can be successfully used for a period of
3 hours.
476 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
There are many side reactions that may occur after the injection
of an anesthetic agent intrathecally. There is a loss of motor tone
which follows the paralysis of the vasoconstrictor fibers in the anterior
nerve roots. The blood pressure consequently may fall to a very low
level requiring the use of such drugs as ephedrine. Radiculitis, neuri-
tis, meningitis, and palsies are some of the undesirable anesthetic
sequelae that have occurred with the use of spinal anesthetics.
OUTLOOK FOR THE FUTURE
Perhaps there is no field in medicine where achievements have been
as great and as far reaching as have been the advances in anesthesia.
The scope of this review purposefully excluded advances in the tech-
niques of anesthesia such as the invention of the anesthetic rebreath-
ing machines, the endotracheal tube, the use of moist soda lime
and conducting rubber devices for the grounding of static sparks.
All of these have made definite contributions to anesthetic success and
safety.
Future researches are certainly to be directed toward the end of de-
veloping a better volatile anesthetic agent than ether. It appears
indeed to be possible. Intravenous anesthesia needs to be made safer.
Other agents need to be investigated further and better antidotes than
are now available must be found. The future must investigate further
and understand more clearly, from the point of view of cellular
physiology, what is meant by that profound hiatus in consciousness,
so glibly referred to as surgical anesthesia.

ASPECTS OF THE EPIDEMIOLOGY OF TUBERCULOSIS?
By LELAND W. PARR
The George Washington University
Despite the difficulty the American Public Health Association had a
short time ago in settling upon a definition of an epidemiologist, I
believe it is not impossible to say what epidemiology is. Epidemiology
is the ecology of disease. It is the life history and environmental re-
lationships of disease. It places less emphasis on how disease acts on
the individual and more on its mass manifestations; little on symptoms,
much on how it spreads and is influenced by all possible variant factors.
The study of tuberculosis is tremendously complex, and the results
that have been obtained are confusing. This is not because the organ-
ism causing the disease is difficult to obtain and study. True, Mycobac-
terium tuberculosis grows slowly, but we have long had satisfactory
culture mediums and suitable experimental animals are readily avail-
able. There is, however, no disease concerning which there are more
disputed concepts and theories. Shortly after the tubercle bacillus
invades the body successfully the tissues take on a new and specific
capacity to react. If into the skin of such a person a tiny bit of the
soluble protein of the tubercle bacillus is injected, there is a decisive
response. The area becomes inflamed, slightly raised, unusually firm,
and somewhat painful. It is, in fact, a typical area of response in in-
flammation. This reaction reaches its height on the second and third
day and thereafter slowly fades away. This is a positive tuberculin
test. By contrast, a person who has not been successfully invaded by
the tubercle bacillus will give no reaction to a similar injection or in-
deed to one many times stronger in its tuberculin content.
The condition of the individual that causes him to react to the injec-
tion of tuberculin is the “tuberculin type of hypersensitivity.” It
would seem simple to determine whether it is better to be tuberculin
positive or tuberculin negative, but it is not. Is this tuberculin type
of hypersensitivity the same thing as immunity? It is not easy to
decide, and any answer given will be disputed. Woodruff and Kelly
(1942) observed: “Before tuberculosis can be controlled successfully

fundamental concepts concerning reactions of the host to the infectious
agent must be clarified. Perhaps the most important of these concepts
is the relation between the hypersensitive or allergic response and im-
munity.” Shall we immunize our children against tuberculosis? We
immunize them against diphtheria; why not against tuberculosis? In
1940, 60,428 persons died of tuberculosis in the United States and only
1,457 of diphtheria. It may be objected that tuberculosis is not a child-
hood disease. It is not, and it is much less so now than it was in 1900,
but in 1940 a total of 2,787 children under 15 years of age died of
tuberculosis, almost twice the total number dying of diphtheria.
When we have clinical tuberculosis where do we get it? Is it from
within—the lighting up of an old arrested focus—or is it from without
by contact, often repeated, with open cases of tuberculosis? We now
favor the latter view, exogenous infection, but it has not been many
years since the former view, endogenous infection, was our gospel.
Years ago we used to speak of the childhood type of tuberculosis. Now
we call it “first infection phase.” In this form of infection the tubercle
bacillus localizes in the outer parenchyma of the lower- or mid-lung
field, and there is developed an area which, when it later becomes en-
capsulated, calcified, or perhaps even ossified, is known as a Ghon
tubercle. Before this happens, however, the little colony of tubercle
bacilli, often too small to be seen with the naked eye, establishes con-
nection with functionally adjacent lymph nodes and there sets up a
focus of tuberculous infection that in time usually becomes calcified
and, if large enough, visible in X-ray plates. The tubercle and its
involved lymph node form the Complex of Ranke. As a usual thing
an individual harboring this pathology suffers, particularly if he is not
a very young or a weakly person, few if any clinical symptoms. Some
years ago it was believed that almost every child had such a “primary
infection.” Now it is known that most children escape any form of
tuberculous infection and that “first infection phase” tuberculosis
comes in both adults and children. Is it the same usually benign
disease in adults that it used to be in children, or is it much more seri-
ous? We have a debatable proposition.
Years ago we used to speak also of the “adult” form of tuberculosis.
Now we call it “reinfection phase” tuberculosis. This is tuberculosis
developing in an individual who has had “first infection phase” tuber-
culosis and is thereby a different host from the individual never con-
tacted successfully by the tubercle bacillus. In this form of disease
the lesion usually appears in the upper third of the lung and does not
involve the functionally connected lymph nodes. When such lesions
heal they show less of calcification and more of resorption and fibrosis.
Spread of this type of disease, which frequently occurs, is by caseation,
liquefaction, and excavation. This “adult” type of disease can, of
EPIDEMIOLOGY OF TUBERCULOSIS—PARR 479
course, occur in a child provided it is an individual who has had “first
infection phase” tuberculosis. It was formerly thought that such dis-
ease arose chiefly from one’s own reservoir of tubercle bacilli held over
from an arrested “first infection phase” attack. The fact that over-
work, worry, undernourishment, and other untoward socioeconomic
factors predispose to tuberculosis fitted in very well with the idea that
each man carried about his own potential tuberculosis and might light
it up as an adult by lowering his personal resistance.
The following quotation from the American Review of Tuberculosis
(Dobbie, 1920) is not the point of view held today:
In adults the problem of preventing infection requires very little attention.
The great majority of adults have already been infected before reaching adult
life. What adults have to fear most is not further infection from without, but an
extension of the infection which they already have, leading to the development
of a group of Symptoms which we are pleased to call the disease tuberculosis. All
adults should of course avoid prolonged and intimate contact with the grossly
careless tuberculous person ; but there is little to be feared through ordinary con-
tact. It has been said that the careful consumptive is not a danger to anyone.
This might be modified to read the consumptive is a grave menace to infants, less
dangerous to children, and no danger at all to adults if reasonable care be
exercised.
Let me emphasize again. We should not be afraid of the tubercle bacillus. For
ourselves, as adults, as a rule we need fear no attack except from those that are
now in our bodies. For the children, since we cannot permanently protect them
from invasion, let us wisely choose the time when the bacilli are first to be met.
If this be done, the tubercle bacilli may be transformed from a menacing enemy
into a protecting friend. This is what should be taught to every adult, as com-
prising the knowledge in accordance with which he should live and act as an
individual.
Today we favor the view that tuberculosis may be contracted from
continued contact with open cases and that its incidence may be
reduced by eliminating sources of infection from milk or meat; by
minimizing contact with open cases through early and accurate diag-
nosis and isolation; and by proper care of those having tuberculosis
including full attention to proper nutrition and conditions of living.
What a change of point of view within a generation! Some areas are
even working on the hypothesis that all tuberculosis can be prevented.
Certainly one cannot develop tuberculosis without first becoming
tuberculin positive. Hence, in certain parts of the country where
conditions are favorable an effort is being made to place tuberculosis
on the county accreditation basis. In 1940 the death rate for tubercu-
losis in the continental United States was 45.9 per 100,000, one of the
finest rates anywhere in the world. It is a reasonable estimate that in
that year about 50 percent of our total population were tuberculin
positive. Minnesota has established county accreditation for tubercu-
losis. This “new idea in human tuberculosis control” provides that a
480 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
county shall be accredited in which there is an average annual death
rate of 10 or less per 100,000 and a tuberculosis infection rate, as evi-
denced by a positive tuberculin test, of less than 15 percent among
high-school seniors. At least 7 of Minnesota’s 97 counties have already
qualified for this honor.
Casual reference to tuberculous infection as something quite time
extensive has probably been confusing to the reader. Reference to
figure 1 should assist in the understanding of the early stages in the
host-parasite relationship of the tubercle bacillus and man.
Some diseases are short-lived and decisive. The patient is sick 2 or 3
days and then is about his work. Such a disease is a mild attack of
influenza. In typhoid fever, on the other hand, the patient may be ill
6 weeks or more, and there is a further period of convalescence to add

to the 6 weeks’ loss of time from work. In tuberculosis there may be a
very gradual onset involving 2 or 3 years before the patient has any
symptoms at all. Probably every person in the United States has
swallowed or inhaled at least one living tubercle bacillus even in this
day of allegedly fine progress in the elimination of tuberculosis. In
half, or more than half of us, the microbe did not successfully invade
the body. (Some of the points involved in the host-parasite relation-
ship bearing on this point are fascinating to contemplate but difficult
to set in order, and they are graphically suggested in figure 2.)
Shortly (2 to 7 weeks) after the tubercle bacillus has invaded the
body the tissues become sensitized and the host is altered profoundly,
just how profoundly we do not yet know. The elicitation of a posi-
tive tuberculin test from such a person is only one aspect of the mat-
EPIDEMIOLOGY OF TUBERCULOSIS—PARR 481
ter. The sensitized individual possesses a new reaction pattern, which
he will keep as long as viable tubercle bacilli remain in his body.
Fortunately, the great majority of sensitized individuals do not
progress farther toward clinical tuberculosis. Such individuals are
harmless to others in their environment, for the tubercle bacilli caus-
ing the sensitization are locked within their bodies. Indeed, as Long
has so well pointed out, the tuberculous individual does not enter into
the epidemiological picture until his pathology is well advanced.
Large lesions caseate, liquefy, and erode into bronchi where bacilli
are spread farther within the lung of the hapless patient or expecto-
rated to the outside world. Interestingly enough, the number of
tubercle bacilli becomes very great in an area of just this type, whereas
they might have been rather few in the same area a month earlier.

Ficure 2.—Some of the factors entering into the host-parasite relationship, which
have much to do in determining the outcome of an infection.
Only a few of those who become tuberculin positive for the first time
will progress to the point where roentgenological evidence can be
obtained that they are ill, and of these by no means all will advance
farther to the point where clinical symptoms can be noted. Further-
more, if taken at the stage of minimal tuberculosis, the disease is easy
to arrest. Even if arrested the individual will still, for a long time,
likely for life, harbor some of the tubercle bacilli that multiplied
within his body. It may seem odd that one can be in good health and
play host to pathogenic organisms. Such a healthy arrested case
should not be a source of danger to others, but it is important to point
out that every extensive survey of adults reveals some of these indi-
viduals who are not satisfactorily arrested cases and who continue to
work or even attempt to enlist in the Army or Navy while really suf-

fering from moderately advanced or even far advanced tuberculosis.
Ironically, many of them are not even aware of the seriousness of their
condition. The tubercle bacillus is not a vicious pathogen despite the
fact that it causes the most important single disease from which man
has ever suffered. It is therefore all the more important that the
facts about tuberculosis be known, so that medical practice and science
can continue adequately in the effort to solve the tuberculosis problem.
What is the present status of tuberculosis as a medical problem ?
First of all, it is worthy of note that there has been a very marked
decrease in this country in the number of deaths from tuberculosis.
In 1900 the rate was 194.4 per 100,000; in 1940 it was 45.9; in 1942 it
was 48.1. There was only 1 death in 1940 where there were 4.2 deaths
in 1900. Not only has the number of deaths decreased but the distri-
bution of those deaths has changed both within the total mortality
picture and within the mosaic of tuberculosis itself. Table 1 will make
some of these changes clear.

Tt will be noted that in 1900 tuberculosis accounted for 11.3 percent of
all deaths. By 1940 this figure had fallen 2.6 times, to 4.2 percent.
Another significant point not shown in the table is that the disease
is becoming pulmonary in type. In 1940, of the 60,428 deaths from
tuberculosis, 55,576 deaths were pulmonary tuberculosis. Just over 8
percent were tuberculosis of the central nervous system, gastrointesti-
nal tract, the bony structures, the skin, the lymphatics, the genitourin-
ary system, generalized tuberculosis, and infection of other organs.
Forty years ago this figure would have been much higher. Other
EPIDEMIOLOGY OF TUBERCULOSIS—PARR 483
changes we may note are a great decrease in the proportion of deaths
from tuberculosis in infancy, childhood, and adolescence, and even in
early married life. There has been a relative increase in tuberculosis
deaths in the middle and later years of life, and there is no longer for
Whites a peak in the curve representing deaths from tuberculosis. It
is rather a plateau extending over three or four of the most important
decades of life.
Tuberculosis mortality is much higher among males than among
females. In the States Relations Division of the United States Public
Health Service there is now a Tuberculosis Control Section headed by
Dr. H. E. Hilleboe. Tuberculosis mortality in the United States, 1939-
1941, was reviewed by three Public Health Service workers in Public
Health Reports for October 1, 1943. They point out that for these 3
years, 1939-1941, the male death rate (53.6) was 41 percent higher than
the female rate (38.1). This excess in mortality among males is higher
for tuberculosis than that from deaths from all causes. For these
3 years tuberculosis was seventh in numerical importance among the
leading causes of death. There are very large racial differences in
tuberculosis mortality, the rate for Negroes in 1940 (123.5) was nearly
three and one-half times that for Whites (36.6). The rate for Indians,
Chinese, and other races was about double that for Negroes. Among
non- Whites tuberculosis was third in numerical importance as a lead-
ing cause of death. Another point, hotly disputed in the epidemiology
of tuberculosis, is whether the Negro tuberculosis experience is the re-
sult of the less favorable socioeconomic conditions under which they
live or is due to inherent biological racial differences between Whites
and Negroes.
Tuberculosis is still among the three leading causes of death for a
relatively large portion of the life span (15 to 49 years of age). It
holds first place at ages 15 to 34, second at 35 to 39, and third at 40 to 49.
For males tuberculosis is among the first three leading causes of death
at ages 15 to 54, and for females at ages 10 to 44. For Whites only, it is
among the first three leading causes of deaths at ages 15 to 49 for both
sexes, ages 20 to 54 for males, and 15 to 44 for females.
Table 1 reveals the fact that though we have made worth-while prog-
ress in the fight against tuberculosis this progress compares unfavor-
ably with advances made in the control of such diseases as typhoid and
diphtheria, and indeed for the whole group listed together in the table,
viz, typhoid, malaria, measles, scarlet fever, whooping cough, and diph-
theria. In 1900 tuberculosis caused only 1.7 times as many deaths as
this arbitrarily selected group. In 1940 this figure became 7.1 by virtue
of the more perfect control of the selected group of diseases. Signifi-
cant, too, is the more marked diminution in the deaths that occur in chil-
dren under 2 years of age from diarrhea and enteritis. That improve-
484 | ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
ment in the tuberculosis picture has occurred is, of course, true. Our
chances of dying of tuberculosis are now computed at a much more
favorable level. It is also of interest to note that the percentage of per-
sons tuberculin positive has been falling. For instance, one of the
earliest reports on the results of tuberculin testing of a student group
was based on a study conducted at the University of Minnesota in 1928.
Thirty-one percent of 2,000 students were found to be tuberculin posi-
tive. In 1941-1942 only 17 percent of 5,481 students were positive.
Thus in 18 years there was a reduction of 45 percent in the number of
tuberculin reactors. Similar information gathered from school surveys
all over the country is much more significant than may on first thought
occur to one. Weare fast becoming a nation of unsensitized individuals
with respect to tuberculosis. There has long been a considerable school
that has maintained that sensitization in the sense of tubercularization
without progression is protection. What, they ask, will be the outcome
as more and more tuberculin-negative children become adults and first
meet the tubercle bacillus under wartime and reconstruction condi-
tions? It is possible that the medical-school tuberculosis problem may
cast light upon this matter, but before that point can be presented it is
logical to consider the effect of war on tuberculosis morbidity and
mortality.
What was the effect on the tuberculosis rate of World WarI? Dr.
Long describes the situation in Europe by observing: “After years
of continuous drop, the rate began rising in 1915 and by 1918 had
reached a figure in all countries about 25 percent higher than at the
beginning of the war.” Wolff has described the privations of the
period as “ an involuntary mass experiment . . . of more epidemio-
logical importance than endless theorizing on the pathology of tuber-
culosis.” These statements may be amplified in the words of an August
1941 article in the Statistical Bulletin of the Metropolitan Life In-
surance Co., in part as follows:
The experience of the World War of 1914-18 affords an indication of what
is likely to occur. None of the belligerent countries escaped an increase in
tuberculosis then, and practically all of the neutral countries of Europe suffered
either an increase in tuberculosis or a slowing up of the prewar rate of de-
cline. The most reliable data for the period relate to the trends among women
and children in England and Germany. Among English women the mortality
from pulmonary tuberculosis rose steadily during the war to a peak in 1918,
when it was over 25 percent higher than in 1913. Among German women the pul-
monary tuberculosis death rate rose slowly at first, but after 1916 the increase was
very rapid, so that by 1918 the rate was nearly 75 percent above that of 1913.
Indeed, in Germany the death rate from tuberculosis among women did not
return to the prewar level until 1921; and this improvement was not main-
tained for a few years following. The rate of increase among German females
was greatest at ages under 20 years. Among children the rate in 1919 was
even higher than during the war.
EPIDEMIOLOGY OF TUBERCULOSIS—PARR 485
Far worse was the situation among the other belligerent countries of the
Continent, but only fragmentary statistical data are available to show the
frightful increases in some of these areas. The statistics of tuberculosis
mortality in France during the war are defective because of the absence of facts
for the invaded regions, where the situation was at its worst. The data for the
uninvaded portion show a sharp increase, particularly in 1917 and 1918. In
the latter year the recorded rate was about 20 percent higher than in 1914. The
aceuracy of these statistics is doubtful, and the actual increase was probably
larger. To some extent the same observation probably holds for Italy, but in
that country even the recorded deaths from tuberculosis in 1918 were over 40
percent in excess of the 1914 rate.
A few examples will show the extremely bad conditions in Belgium and in
eastern and southeastern Europe. In Brussels the death rate from tuberculosis
doubled during the war, from 177 per 100,000 in 1914 to 390 in 1918. In Vienna
the rate in the period 1915-18 was 20 percent higher than in 1911-14, and in
the early postwar years it increased to 50 percent above the prewar rate. In
Budapest the number of deaths from the disease in 1917 was nearly double
that of 1913, and it was but little less in 1918. In Warsaw the rate in 1917
was 840 per 100,000, as compared with 306 in 19138; in Cracow during the same
period the rate increased from 487 to 908 per 100,000. In Belgrade the tubercu-
losis death rate in 1918 reached the almost incredible figure of 1,400 per 100,000.
Typical of the trend of tuberculosis in the neutral countries of Europe dur-
ing the World War are the experiences of the Netherlands and Switzerland.
In the former, the death rate from the disease rose steadily, until in 1918 it
was nearly 50 percent above the 1914 figure. In Switzerland, where the trend
was Sharply downward before the war, the rate continued to fall at first, but
rose in the latter part of the war to a peak of 207 per 100,000 in 1917, or 6
percent above the rate in 1914.
In our own country the mortality from tuberculosis showed little change
during the World War period as a whole, but even here there was a slight
increase in the death rate during the period of our active participation in the
war. Thus the death rate in the original Registration States declined from
148.6 per 100,000 in 1914 to 148.8 in 1916, but then rose to 147.1 in 1917 and
further to 151.0 in 1918.
These increases come about through break-down in resistance to
disease on the part of the host, to increase in opportunities for infec-
tion, and to a decrease in or, indeed, collapse of facilities available
for proper recognition, isolation, and treatment of disease. Spe-
cifically some of the factors for tuberculosis are:
1. The entrance of women into heavy and fatiguing industry.
2. The return of the older age groups to active employment.
3. The return to work of persons of either sex or any age physically
unfit to work.
4, Long hours of work often emotionally compensated for by long
hours of strenuous or injudicious relaxation—“burning the candle at
both ends.”
5. Relocation in areas of intense war-industry activity resulting in
congested living conditions without adequate sanitary facilities.
486 § ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
6. Relocation in areas of intense war-industry activity where tuber-
culosis rates may be high by persons coming from areas where tuber-
culosis rates are low.
7. Congestion in concentration camps, war prisoners’ camps, evacua-
tion depots or camps, and air-raid shelters.
8. Use of hospital beds formerly allocated to the tuberculous for
more urgent war needs or actual destruction of hospital facilities by
the bombings or bombardments of “total” warfare.
9. Loss of trained personnel to the war need—physicians, nurses,
attendants, laboratory workers, and social workers—all needed to care
for an increasing load of tuberculosis patients.
10. Food shortages, both qualitative and quantitative.
11. Impossibility for perfect rest conditions so necessary for the
tuberculous and the pretuberculous.
12. Worry and anxiety over the fate of one’s relatives or even of
one’s country.
One of these points deserves particular emphasis as far as this
country is concerned. As pointed out in an editorial in the New
England Journal of Medicine for January 27, 1944, “it is estimated
that 25,000 had been diagnosed (at induction) to have a disease that
neither they nor their friends would have suspected under prewar
conditions. And how are these patients, many of whom need sana-
torium treatment, going to be accommodated by the currently re-
stricted personnel of the sanatoriums?” Early in 1942 the number of
beds for tuberculosis patients in this country totaled 97,726, or 1.62
per annual death, which is at best well below the minimum standard
set at 2 beds per annual death and far below the more ideal standard
of 3. In 1942 only seven States and the District of Columbia had met
the minimum standard. It is quite possible that under present con-
ditions of personnel shortage the paper figure of 97,726 beds available
for tuberculosis patients must be considerably discounted. Where
fighting is actually going on the condition is, of course, much worse.
Just what has happened thus far in the present war? Hilleboe
states that by the last half of 1942 in the United States the Bureau of
the Census, by a sampling process, had sensed an increase in tubercu-
losis in the “critical areas,” although the total figure for 1942 repre-
sents an all-time low rate of 43.1 per 100,000. In England he notes a
13 percent increase in deaths from all forms of tuberculosis in 1941
as against 1938. This represents more than 3,000 additional deaths
each year from a preventable disease. Recently in the British Medi-
cal Journal (January 8, 1944) it is stated that in Belgium the regis-
tered cases of tuberculosis increased from 69,079 in December 1941, to
109,511 in February 1943, an increase in rate from the high figure of
§30 per 100,000 to the startling figure of 1,330 per 100,000. If there
EPIDEMIOLOGY OF TUBERCULOSIS—PARR 487
are 10 clinical cases of tuberculosis for every annual death, we have in
the United States less than 600,000 cases at the present time or only
six times as many as now exist in little Belgium, which has perhaps
only one-twentieth of our population. Many of our people are in, or
shortly will be in, these unfortunate European countries. It would
seem a safe prophecy to venture that the tuberculosis rate in this
country may be slightly increased for a short period, but it should
within a very few years again resume its downward trend.
In view of the very low rate now obtaining (43.1 in 1942) it would
be reasonable to expect a greater set-back relatively than we experi-
enced at the end of World WarI. The magnitude of this set-back may
not be so much one of significantly increased rate as of slowness to get
under way again on the downward trend. For a disease as widely
seeded in our population as tuberculosis and for a population more
completely involved in abnormal war activity than was the case in
World War I, it would not be surprising if this were to be so and the
very favorable rates now attained would seem to be advanced posts
we may have to abandon for some time. One factor in this slightly
pessimistic prediction is our closeness to and commerce with the rest
of the world in many parts of which tuberculosis is rampant.
At one time the hope was expressed that we might be able to eradi-
cate tuberculosis by a given date—say 1960. It should be understood
that any such statement was merely a slogan, a cry behind which to
rally the forces fighting the great white plague. As Frost ably
pointed out in one of his last papers, entitled “How Much Control of
Tuberculosis?” it “is not necessary that transmission be immediately
and completely prevented. It is necessary only that the rate of trans-
mission be held permanently below the level at which a given number
of infection-spreading (i. e., open) cases succeed in establishing an
equivalent number to carry on the succession. If, in successive periods
of time, the number of infectious hosts is continuously reduced, the
end result of this diminishing ratio, if continued long enough, must
be the extermination of the tubercle bacillus.” I am not aware that
Frost ever set any date for this millennium. As a very humble stu-
dent of epidemiology I am sure I cannot. I doubt though if under
present war conditions we have any reason to anticipate any lowering
of the death rate for the entire country from 43.1 to even 10 per 100,000
for several decades. Many millions of Americans are already tuber-
culin positive; thousands of unrecognized advanced cases of tuber-
culosis exist today; Europe and indeed most of the rest of the world
is heavily tubercularized. It is too much to expect tuberculosis death
rates to continue to drop as rapidly as they have in the past. To reduce
194.4 by 10 percent is not so difficult as to reduce 43.1 by 10 percent.
619830—45——32
488 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
One other point that Frost makes deserves our attention. He states:
“It is highly probable that the cyclic changes in prevalence which
are observed in some diseases are brought about chiefly by evolutionary
changes in the characteristics of the specific microorganisms, the causes
of which are to be found in uncontrolled natural forces.” Frost men-
tions scarlet fever and diphtheria as two of the diseases that within
the past 100 years have greatly changed, although in the case of
diphtheria the change reversed itself and diphtheria is again a prob-
lem of some significance in parts of the world. Smallpox, since the
Spanish American War, has been relatively mild when it has occurred
in this country, and in 1942 caused but two deaths. It could be pos-
sible that cyclic changes may be taking place in the nature of the
tubercle bacillus making it less invasive, but whether this is so, how
long it will continue, or whether it will reverse are propositions very
difficult of proof. Again, case finding among medical students and
physicians yields results with suggestive implications for this point.
Case finding means looking for cases of a given disease. It is done
to discover unrecognized cases that should be brought under treatment
for their own good and isolated or educated so that the public health
may be protected by removing active sources of infection. Although
useful for several diseases such as malaria and hookworm, even syphilis,
case finding is particularly adapted to tuberculosis. It is possible
through tuberculin testing to discover those belonging to the tuber-
culin-positive group of persons who can have tuberculosis and, by
X-ray examination, to detect which of these have physical signs almost
certain before long to produce clinical symptoms. Such individuals
may be satisfactorily arrested with a minimum of treatment and loss
of time whereas if the minimal case is not discovered in its incipiency
a moderately advanced or even a far advanced case may result which
is difficult or impossible to arrest. The great advantage to the careful
examination of the would-be soldier or sailor is that tuberculosis is
discovered, as never before, in the stage in which it is possible to do
something about the matter. From the first approximately 400,000
men appearing for the Canadian Army, 1 percent were rejected for
tuberculosis. Of 3,530 of these rejectees, there were 1,970 with minimal
tuberculosis, 1,298 moderately advanced cases, and 262 far advanced
cases. This ratio of the different clinical types (and the same is true
for all other large-scale screenings) is the exact reverse of what occurs
when we let nature take its course. In the past, minimal cases have
been a minority in the treatment program with moderately advanced
and far advanced cases constituting the great majority of cases coming
to the attention of the physician and the care of his sanatorium. It
is to be hoped that although we are at war care will be taken that the
EPIDEMIOLOGY OF TUBERCULOSIS—PARR 489
young men and women found to have tuberculosis will be adequately
cared for.
Tuberculin testing is time consuming and costly and, I regret to
say, is sometimes omitted from the case-finding set-up. Celluloid
films, 14 by 17 inches are also very expensive, and several substitutes
have been worked out making it possible to examine the lungs of all
members of a group (a good case-finding team can do 500 persons a

day) at a reasonable cost. While this expedient works and is there-
fore justified, from the epidemiological point of view it is distinctly
faulty because the tuberculin test gives information we must have for
the proper understanding of the disease, and the large plate provides
a permanent record unequaled by most of the less costly substitutes.
At George Washington University Medical School, through the in-
terest and cooperation of the dean, a proper and complete case-finding
program has been in progress almost 5 years. The organization and
operation of this program are graphically indicated in figure 3.
490 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1944
It will be seen from figure 3 that five different agencies must be
integrated in the program. ‘These are the tuberculin-testing group,
the X-ray group, the chest-physician group, the laboratory group,
and the sanatorium group. Coordination is best effected by that
agency having most student contact, which in our institution is the
tuberculin-testing agency represented by the writer. When there is
sufficient interest in the program on the part of the coordinator the
cooperation of the other agencies is easily obtained and cheerfully
given. In addition to the value of such a program to the health of
the student body the tuberculosis case-finding program is an admirable
laboratory experiment in preventive medicine.
When it was realized that exposure to open cases of tuberculosis had
to be considered as an important factor in the etiology of the disease
it was only natural that thought turned to medical personnel—phy-
Siclans, nurses, hospital attendants, and students of medicine and
nursing—as persons having an industrial hazard with respect to
tuberculosis. Three examples will illustrate the validity of this
assumption. Diehl and Myers reported in 1940 that at Minnesota it
had been possible to check effectively on the careers of 1,673 of 1,894
medical students graduating from 1919 to 1936. Among these there
were 107 cases of tuberculosis, 5 occurring before college, and 47 after
college. It was found that 46 deaths had occurred among the 1,673,
of which 11 had been from tuberculosis.
Again it is well known that inmates of our mental hospitals form
a group among whom tuberculosis is especially important. A recent
study of such individuals in New York revealed that on the average ~
tuberculosis deaths in such groups in this State were relatively twelve
times more numerous than for the State as a whole. In certain such
institutions in this country where careful case-finding programs have
been carried out on the attendants, rates of infection and actual evi-
dence of disease much higher than occurs for other individuals in the
same area have been found.
Thirdly, the early experience at the University of Pennsylvania
revealed the significance in that institution of tuberculosis for medi-
cal students. Less than 10 years ago among 514 Pennsylvania stud-
ents 5.8 percent of significant tuberculosis was found. Happily, re-
sults in most other schools are much better, and in fairness to Penn-
sylvania it should be pointed out that subsequent studies there have
revealed a very much lower rate. Nevertheless, there seemed to be
much logic to the statement made in 1930 by Stiedl of Trudeau when
he said: “Tuberculosis might be called an industrial hazard for the
medical profession. It is the most important chronic disabling dis-
ease for the medical student, the young physician and the nurse.”
EPIDEMIOLOGY OF TUBERCULOSIS—PARR 491
In 1939, a case-finding program at George Washington University
School of Medicine was instituted. For many years prior to this, as
I shall show presently, we had been making tuberculin surveys of all
students, but a complete case-finding program had not, prior to 1939,
been in existence in our institution. It is greatly to the credit of my
former colleague, Dr. John H. Hanks, now in the Philippines, and
Dr. David James, then president of the junior class, that they fur-
nished much of the initial enthusiasm needed to get the program
under way. The interest from the first of Dean Walter A. Bloedorn
and the whole-hearted cooperation of the roentgenological and chest-
physician group insured the success of the project. We have already
indicated in a diagram how tuberculosis case finding works. It
remains merely to give some of the results and to make a few
observations.
The percentage of tuberculin-positive reactors among 14 consecu-
tive classes totaling 1,007 students at George Washington University
School of Medicine is shown in table 2. With so many tuberculin-
negative students in school, a situation true in most other schools also,
it was only natural to expect that many of them would become tuber-
culin positive. A good many of these tuberculin-negative students
did become tuberculin positive but not nearly so many of them as one
might expect. Washington is in an area of high tuberculosis mortal-
ity (1940 figures, entire U. S. A., 45.9 per 100,000 population; District
of Columbia, 64.4; Maryland, 79.1; Virginia, 58.1), and our students
certainly come into contact with tubercle bacilli. We were particu-
larly impressed by the large number of those who were originally
tuberculin negative and who remained negative through a complete
medical education in Washington, D. C. Data on this point are
presented in table 3.

Of the 64 students, originally tuberculin negative, who became tuberculin positive, 4 developed clinical
tuberculosis—1 man losing 2 years, 1 losing 1 year, and 2 no time loss. All 4 at present are in fine physical
condition.
We were further impressed by the fact that a considerable number of
medical students who gave weakly positive tuberculin tests later be-
came negative. Students were not followed prior to 1939 through all
semesters; hence the figures on this point do not include all our ap-
proximately 1,000 students. Of those followed (666), however, 134
have reacted only to the strong dose of purified protein derivative.
This represents a low grade of sensitivity due perhaps to an almost
negligible original sensitizing lesion or to a lesion almost completely
sterilized or possibly, in an occasional case, to a nonspecific reaction.
Nine classes are included in this aspect of the study, four of which are
still in school, on whom obviously the data are not yet complete. In
the five classes concerned that have graduated 56 showed weakly
positive reactions as freshmen. Of these, 18 showed stronger reac-
tions as they progressed through school, indicating some sort of sensi-
tizing or immunizing process at work. Six became entirely negative
and one became weaker in tuberculin reactivity, 22 remained the same,
and a few of the original freshmen did not graduate. Among the 666
students of these nine classes 319 were positive to some strength of
tuberculin as freshmen (47.9 percent). Of these, 134 (42.0 percent)
were weak reactors. Among the 323 students of the last four classes
there were 139 reacting to tuberculin (48.0 percent), of whom 78 were
only weakly positive (56.1 percent). Among the 348 students in this
series who have graduated there were 180 tuberculin reactors (52.4
percent), but of these only 56 were weak reactors (31.1 percent).
Several points may be made regarding these data. An environ-
ment containing tubercle bacilli does not prevent a certain number
of weakly positive tuberculin reactors from becoming negative. These
individuals may be thought of as resistant strains of the human race.
Our newer students are showing not only a lower total tuberculariza-
tion rate but also a tubercularization of less intensity. Tubercle ba-
cilli in the environment are doing less to medical students than
EPIDEMIOLOGY OF TUBERCULOSIS—PARR 493
formerly. This is susceptible to three interpretations. The tubercle
bacilli in the environment are becoming fewer; they are losing in-
vasiveness and virulence; or, thirdly, the resistance of the young white
American to tuberculosis is increasing. The first point is obvious
but can hardly be the whole explanation. I believe we miss the full
significance of the data if we do not also allocate some importance
to each of the other two explanations.
Weight is added to this suggestion when we consider that the total
number of tuberculin-negative students in the school, all presumably
susceptible to successful invasion by the tubercle bacillus, is increasing.
This number is the census made up each semester after the tests are’
done. In November 1941 there were 147 tuberculin-negative students
in the school. In June 1942 this number was 157. In November 1943
it was 166 among 313 students, or a student body only 46.9 percent
tuberculin positive. There has been a slight increase in the total
number of students in the school, but this has been balanced off by the
fact that our last two classes, though the initial tuberculin-positive
rate was low, had higher percentages than the average of the preceding
four classes (48.3 as against 41.3 percent). Furthermore, since this
program was started in 1939, only nine students have been found with
minimal tuberculosis, although three others were detected shortly
following graduation. At the present time, with 313 students in
attendance, not one has minimal tuberculosis. This fine record sur-
passes that revealed in almost any mass survey of adults. Among
28,098 United States Government employees recently surveyed, 1.1
percent had recognizable tuberculosis (60.7 percent minimal; 35.3
percent moderately advanced; 4.0 percent far advanced).
It has been our purpose in presenting these observations to empha-
size that, although remarkable progress has been made in combating
tuberculosis, that progress has not equaled advance achieved in con-
trolling other well-known diseases. We must believe that tuberculosis
is still a major problem. Its eradication may be set back by the war
but not irrevocably. Tuberculosis morbidity and mortality can be
reduced to a satisfactorily low level, but I do not expect to see in my
lifetime, the absolute elimination of the disease. Our evidence sug-
gests that the tuberculosis problem is not at present unduly significant
for medical students and that there is some ground for considering
either that the young white adult has more resistance to the tubercle
bacillus than his father possessed or that the Mycobacterium tubercu-
losis is losing some of its virulence. Possibly a little of both is true.
