SPRING MEETING 
Mary Gray Bird Sanctuary, Fayette County, Indiana 

MINUTES OF THE EXECUTIVE COMMITTEE MEETING 

April 23, 1971 

The meeting was called to order at 4:39 pm by President 
Samuel Posthlethwait in Earl Brooks Hall, Mary Gray Bird Sanctuary, 
near Connersville. Nineteen members were present. The president re- 
ported briefly, chiefly noting- points of the agenda which were 
considered later in the meeting. The secretary moved the approval of 
the minutes of the November 5, 1970, meeting, which had been 
duplicated and distributed. Seconded and carried. 

Treasurer: Rev. Damian V. Schmelz distributed duplicated copies 
of his report for the period January 1 to April 23, 1971. It was moved, 
seconded, and carried that it be accepted. 

Academy Foundation Committee: William A. Daily, Chairman, 
reported that legal counsel had been retained to clarify the tax status 
of the academy with the United States Internal Revenue Service. He 
moved that attorney Donald G. Sutherland be granted Power of 
Attorney to act for the academy in tax matters. Seconded and 
carried. (This action had previously been taken by the Council.) 

Bonding Committee: Robert M. Brooker, Chairman, recommended 
no change in our program. 

Academy Representative on the A.A.A.S. Council: Willis H. Johnson, 
Representative, reported the following interesting actions at the 
December, 1970, meeting of the council: 1) Passed resolution recom- 
mending phaseout of the use of herbicides in Southeast Asia; 2) Passed 
resolution recommending that all scientists start using the metric 
system in their publications and also recommending that the government 
establish a national policy on its use; 3) Passed resolution reaffirming 
its commitment to equal opportunity for all scientists regardless 
of sex, race, creed or national origin. 

A new rule of the A.A.A.S. requires representatives from affiliated 
organizations (such as ours) to serve 2-or-more-year terms. It was 
moved that the constitution of the academy be amended as follows: 
(italicized words added) 

"Article V, Section 1. The following named committees shall be ap- 
pointed by the President, to serve for one year, except as noted other- 
wise below and except as rotation is provided, and except as otherwise 
provided they shall be announced . . . 

"(1) The Academy Representative on the Council of the American 
Association for the Advancement of Science. This person 
shall serve for a three-year term beginning January 1, 1972, 
and every 3 years thereafter. 

"(2) Auditing. . ." Seconded and carried.

Minutes of the Executive Committee 7 

Auditing Committee: Robert Dolphin, Chairman, stated that no 
report was necessary at this time of year. 

Library Committee: Mrs. Lois Burton, Chairwoman, reported that 
in December the Academy received a grant of $15,000 from Lilly 
Endowment, Inc., to be expended in general support of the John 
Shepard Wright Memorial Library. The amount is on the Treasurer's 
books as Lilly Fund IV. We plan to begin carrying out provisions under 
this grant during the coming summer. 

A second mailing of Volume 79 of the Proceedings has been com- 
pleted, courtesy of the Indiana State Library. The total number mailed 
to members to date is 1,127. 

Monograph Number 2 has been received and is ready for mailing 
under our Exchange program to libraries, universities, and scientific 
societies. 

Some sales of Natural Features of Indiana were made. Sixty-five 
copies remain in stock. 

Program Committee: Mrs. Carroll A. Markle reported no prob- 
lems. 

Publications Committee: Marion T. Jackson, Editor, reported that 
Monograph 2 has been published and will be distributed free to members 
who request it, pending investigation of costs and past actions of this 
committee. Volume 80 of the Proceedings will be published about 
September and will be larger than the last volume. The possibility of 
page charges or of a limitation of allowable published papers per year 
per member should be considered for future volumes. 

Relation of Academy to State of Indiana: William A. Daily, Chair- 
man, reported that no change had been made in the State's budget 
allowance for publication of the Proceedings. 

Membership Committee: Eliot C. Williams, Chairman, reported 
no radical changes. 

Invitations Committee: The secretary reported official approval 
from Indiana Central College of that school as our meeting site for 1973. 

Emeritus Members Committee: The secretary read a report from 
Chairman Ralph Cleland which recommended that Ralph W. Lefler be 
elected to emeritus status. It was moved, seconded, and carried that Dr. 
Lefler be so elected. 

Natural Areas Committee: Rev. Damian V. Schmelz reported that 
the registry of natural areas in the state has been extended, intensified, 
and more effectively computerized. 

Speaker of the Year Committee: The committee consisted of Ralph 
F. Cleland (chairman), Willis H. Johnson (reporting), and Arnold 
Ullstrup. Willis Johnson moved that, 



8 Indiana Academy of Science 

The Special Lecturer should be paid an honorarium of $500.00 by 
the Academy. 

A committee should select the Special Lecturer each year. While 
the Executive Committee might do this and the contacting of the 
colleges, you may prefer to appoint a special committee for this purpose. 
If you decide on a special committee of three, each should serve three 
years except in the beginning when one should serve for three years, 
one for two, and one for one. Thus, after the first year one new member 
would be appointed by the President each year. 

The job of the committee would be two-fold: 1) to select the 
speaker, and 2) to contact the colleges. 

The speaker should be a member of the Academy (preferably). He 
should be a forceful speaker, able to communicate with young 
people. His subject should be relevant. It might be on his research, but 
it should be related to social problems. On the other hand, it might be 
on a social problem or problems not directly related to his research. The 
committee should know the subject of a prospective speaker before he 
is selected. It is understood that the speaker will give his lecture before 
the fall meeting of the Academy, preferably in a session immediately 
following the lunch period. This lecture will be printed in the Proceed- 
ings of the Indiana Academy. In addition to the lecture before the 
Academy, the speaker will give his lecture at four or five colleges in 
the state. It is understood that this is a program for the colleges of the 
state. The second job of the committee each year will be to contact the 
colleges where the speaker will give his lecture. Once a college has been 
served it should not be contacted again for a special lecturer until all 
of the colleges of the state have had an opportunity to have a special 
lecturer. It may be that the committee will want to select colleges in 
a particular region of the state for a given year. It is understood that 
the colleges will pay for any meals and lodging involved in the visit; 
the colleges will not pay an honorarium. 

Seconded and carried. 

Willis H. Johnson moved that the speaker of the year for 1971 be 
Alton A. Lindsey, with first alternate William R. Breneman and the 
second alternate Charles B. Heiser, Jr. Seconded and carried. 

Science and Society Committee: Willis H. Johnson, Chairman, 
reported that the committee and its Executive Director, Helmut 
Kohnke, had been able to advise several branches of the state and city 
governments concerning environmental and other scientific problems. 

The President reported that a group of engineers at Purdue Uni- 
versity had requested the formation of an Engineering Section of the 
Academy. It was moved by Rev. Damian V. Schmelz, seconded, and 
carried, that an Engineering Section be organized at the 1971 fall meet- 
ing; that the section follow all appropriate procedures and restrictions 
consistent with the constitution and by-laws of the Academy. The 
President appointed Robert L. Swaim Chairman for 1971. 



Minutes of the Executive Committee 9 

Marion T. Jackson reported the recent death of Georg K. Neumann, 
who was the elected 1971 chairman of the Anthropology Section. The 
President appointed William R. Adams Chairman for the remainder of 
the year. 

There was an extended discussion of some recent attributions by 
news media of "official Indiana Academy of Science" positions to public 
statements by certain members. Mrs. Fay K. Daily moved that the 
Parliamentarian draft a disavowal statement for publication by the 
Academy, disassociating the academy officially from all public 
statements by its members. The motion was seconded; a vote by show 
of hands was tied. It was moved by Willis H. Johnson, seconded, and 
carried that the motion be tabled until next meeting. 

The President requested an investigation of the possibility of hiring 
an Executive Secretary. No objection being raised, consent was 
declared. 

The President stated : 

"The President of the Academy by law is the official appointee 
to the Natural Resources Commission. It is believed that it would 
serve the best interests of the Academy and the Natural Resources 
Commission if the law were changed to permit the appointee to 
be the president or his representative." 

It was moved by Willis H. Johnson, seconded, and carried that the 
Academy petition the Indiana State Natural Resources Commission and 
the legislature of the State of Indiana to change the law so that the 
member of the Natural Resources Commission not be "The President 
of the Indiana Academy of Science", but, rather, "The President of the 
Indiana Academy of Science or his designated representative." 

On motion the meeting adjourned at 6:32 PM. 

Approved October 28, 1971. 

Respectfully submitted, 
J. Dan Webster, Secretary 



MINUTES OF THE GENERAL SESSION 

April 23, 1971 

The meeting was called to order by President Samuel N. Postleth- 
wait at 7:49 PM in Earl Brooks Hall, Mary Gray Bird Sanctuary, near 
Connersville. Thirty members were present. 

The secretary moved the following proposed amendment to the by- 
laws of the Academy — 

Article III, Section 1. Delete the last clause, reading, "provided 
that any bill for fifty dollars or more shall be approved by the presi- 
dent." As a result, Article III, Section 1, would read: "The treasurer 
is authorized to issue checks in payment of bills submitted by 
officers or committees for which provision has been made in the 
budget for that year." 

Seconded and carried. (This was the second passage; the amend- 
ment is now effective.) 

A. T. Guard moved the following resolution — 

The Indiana Academy of Science members and friends here 
assembled express their most sincere appreciation to Dr. Carrolle 
A. Markle and Dr. W. K. Stephenson for the fine program which 
they have arranged. Our sincere thanks are extended to the officials 
of the Indiana Audubon Society and especially to Mr. and Mrs. 
Denzil Barricklow, Resident Naturalists of the Mary Gray Bird 
Sanctuary, for making their facilities available to us. 

Our thanks also go to Dr. Gary Barrett of Miami University 
for his timely, instructive and interesting address on "The New 
Ecology". 

We also wish to express our appreciation to those ladies who 
served us such excellent meals. 

Our appreciation is extended to the leaders of the various field 
trips which are always such an integral part of the spring meeting 
of the Academy. 

Seconded and carried. 

Dr. Carrolle A. Markle announced details of field trips and meals. 
The evening feature was an illustrated lecture by Gary Barrett entitled 
"The New Ecology". 

The meeting adjourned at 9:15 pm. 

Approved October 28, 1971. 

Respectfully submitted, 
J. Dan Webster, Secretary

College. Twenty-two members were present at the start; ten more came 
in later. The secretary moved the approval of the minutes of the 
executive committee and general session meetings of April 23, 1971, as 
duplicated and distributed. Seconded and carried.

Total grants approved $2,862. 

Also, one more proposal is under consideration and another from 
last year has been extended. A manuscript by Sherman Minton, "Rep- 
tiles and Amphibians of Indiana," has been approved by the Publications 
Committee as Monograph No. 3; the research committee will consider 
underwriting the publication cost. 

Academy Representative to the A.A.A.S. Council: Willis H. John- 
son reported no actions by the council relevant to our Academy, 

Youth Activities Committee: A written report by Paul E. Klinge, 
Chairman, was presented by Donald R. Winslow. The anti-animal- 
experimentation rule set up by the National Science Talent Search still 
hampers Indiana student biologists. Reorganization of the entire youth 
program is under discussion, but no proposals are ready. 

Science Talent Search Committee: A report was written in by 
Wendell F. McBurney, Director. The report was accepted, but no action 
was taken on the request to support the position of the Indiana 
Science Talent Search Committee regarding experimentation on 
vertebrate animals. 

Science Fairs: A report was written in by Karl Kaufman, 
director. 

Indiana Junior Academy of Science: Donald R. Winslow presented 
his report and distributed copies of the program for the forthcoming 
Saturday meeting. It appears that a valuable and interesting meeting 
for high school students is scheduled. It will include a report on a 
successful high school applied ecology program, six invited research 
reports by high school students, an address by Lawrence E. Poorman, 
and a tour of the Earlham College research facilities. 

Library Committee: Mrs. Lois Burton, Chairwoman, reported that 
600 square feet of additional floor space have been obtained, but without 
the needed shelving. Four hundred volumes have been bound. Sixty- 
six additional journals have been received as exchange; more are being 
sought. 

Trustees of the Academy Foundation: William A. Daily gave this 
annual report, as of September 30, 1971 — 

I. Foundation fund 

Last year's balance $ 979.96 

Receipts 897.05 



Minutes of the Executive Committee 13

Disbursements ................................. 14,590.11 

Balance ....................................... 18,955.07 

Market value of securities held .............. ,$596,440.00 

Program Committee: Mrs. Carrolle A. Markle, Co-chairman, re- 
ported that no serious problems were handicapping her committee, 

Publications Committee: Marion T. Jackson, Editor and Chair- 
man, reported. The cost of the current Volume 80 of the Proceedings 
now being distributed, has risen sharply over preceding years, but no 
final figure is yet available. The size increase was 9% in the divisional 
reports section; had there not been a more careful review system ini- 
tiated, this increase would doubtless have been much greater. The 
10-year index is due in Volume 81. 

Frank A. Guthrie moved that Monograph No. 2 and all subsequent 
monographs be sold to members at one-half price; it was seconded and 
carried. (The vague action on the same subject taken April 23, 1971— 
see minutes — is herewith rescinded.) 

Newsletter: Frank Guthrie, Editor, reported that the last issue 
came out in December, and that the next will be published in November 
1971. 

Relation of Academy to the State of Indiana: As it has for many 
years, the legislature in 1971 appropriated $4,000 per year for the next 
two fiscal years to aid printing of the Proceedings. 

Fellows Committee: Benjamin Moulton, Chairman, moved the elec- 
tion of these 7 members to the rank of Fellow of the Academy — 

Robert E. Dolphin Holm W. Neumann 

John D. Favinger B. K. Swartz, Jr. 

John W. Hart Gertrude L. Ward 
Edward V. McMichael 

The motion was seconded and carried. 

Invitations Committee: A report was written in by James R. 
Gammon, Chairman. We will meet at St. Mary's College in 1972, at 
Indiana Central College in 1973, and at DePauw University in 1974. 

Preservation of Scientific and Natural Areas Committee: Robert 
O. Petty, Chairman, reported that a current listing of 429 areas and 
their outstanding features is on magnetic computer tape and available 
on request. 

Speaker of the Year Committee: Willis H. Johnson, Chairman 
pro tern, reported that the list of colleges where speaker of the year 
Alton A. Lindsey would appear was under consideration. 



14 Indiana Academy of Science 

Science and Society Committee: The death of Ralph F. Cleland 
has been acutely felt by the committee. 

A booth which was operated with much effort at the recent state 
fair resulted in some publicity. 

Special Committee on Executive Secretary: Jerry Nisbet, Chair- 
man, reported that his committee had decided that the idea of having 
an Executive Secretary was valid, but expensive. At present, it is beyond 
our means unless we can find a considerable new source of funds. 

When the President called for old business, Mrs. Fay K. Daily 
called for her tabled motion from the April 23, 1971 meeting. (See page 
9.) Mrs. Daily stated that her motion should read: "The 
Indiana Academy of Science shall not be responsible for public 
statements of opinion of its members concerning governmental or 
political matters." After further discussion, the motion was put to a 
vote by show of hands; it was defeated. In discussion, all were agreed 
that the Academy must be chary of expressing opinions on political or 
governmental matters officially. However, public expressions by 
members, or even officers, not based on official actions may be reported 
in the public news media as the news media prefer. Alton A. Lindsey 
moved that any statements made by him, as Speaker of the Year, in 
1971-72 be considered individual opinions and not official positions of 
the Academy. Seconded and carried. 

New business was called for. William J. Brett suggested the estab- 
lishment of an animal behavior section, or at least the investigation 
of such a possibility for next year. Rev. Damian V. Schmelz moved that 
the annual dues schedule be increased to: Regular $6, Family $8, Student 
$3, with no change in the initiation fee; the motion was seconded. Frank 
A. Guthrie moved to amend so that the action was merely a recommen- 
dation to the budget committee and council at their forthcoming 
December 4, 1971 meeting; the amendment was seconded and 
carried. Helmut Kohnke moved to amend to increase the recommended 
dues schedule to $8, $10, and $4 but abolishing the initiation fee; 
this amendment was seconded, but defeated. The original motion was 
carried as amended. 

A showing of his pictures from the Galapagos Islands by Robert 
Cooper after the close of the meeting was announced. 

The meeting adjourned on motion at 10:39 pm. 

Approved April 28, 1972. 

Respectfully submitted, 
J. Dan Webster, Secretary 



GENERAL SESSION—OCTOBER 29, 1971 
RICHMOND, INDIANA 

President Postlethwait called the meeting to order at 2:07 pm in 
Wilkinson Theater of Runyan Center, Earlham College. Provost Helen 
Hole welcomed us to Earlham College in a few gracious words. The sec- 
retary read a brief summary of the actions of the executive committee 
at its meeting last night, and moved its acceptance. Seconded and 
carried. The secretary moved approval of the following amendment to 
the constitution; which had been passed by the executive committee 
on April 23, 1971 : 

Article V, Section 1. The following named committees shall 
be appointed by the President, to serve for one year, except as noted 
otherwise below and except as rotation is provided, and except as 
otherwise provided they shall be announced . . . 

(1) The academy representative on the council of the American 
Association for the Advancement of Science. This person shall serve 
for a three-year term beginning 1 January 1972 and every 3 years 
thereafter. 

(2) Auditing . . , 

(added words italicized) 

Seconded and carried. 

Mrs. Fay K. Daily named the members of the Academy who had 
died during the past year. (See Necrology Report, page 27.) A 
moment of silence was observed in their honor. 

As speaker of the year, Dr. Alton A. Lindsey gave an outstanding 
lecture, "The Role of Scientists in the Preparation and Evaluation of 
the New Environmental Impact Statement Requirement." Recent history 
of the federal government shows encouraging new laws for protecting 
the environment, much lip service to conservation by many politicans, 
but little real protection of the environment. 

The meeting was temporarily adjourned at 3:15 PM. 

The meeting was recalled to order at 8:08 pm, after dinner in the 
Friend's Room of Earlham Hall by President-elect Behrens. The secre- 
tary read these results of the elections of chairman in the various 
sections : 

Section 1972 Chairman 1973 Chairman-elect 

Anthropology Edward Dolan 

Botany Willard F. Yates C. L. Gehring 

Cell Biology Charles W. Goff 

Chemistry Richard Pilger William Nevill

Dr. Arthur T. Guard moved the following resolution — — 



Members of the Indiana Academy of Science, here assembled, 
wish to express our sincere thanks to Earlham College for opening 
their facilities to us for our meetings. We are also grateful to 
Provost Helen Hole for her warm words of welcome. Our thanks 
also go to Dr. A. A. Lindsey for his timely, instructive and 
interesting address. We extend our appreciation to Carrolle A. 
Markle axid William K. Stephenson, co-chairmen of the program 
committee, for their careful planning of the many details associated 
with o ir meeting and also to the chairmen of the various 
divisions: meetings that make the fall meeting both stimulating 
and instructive. 

It was seconded and carried. The resolutions committee consisted 
of Robert O. Petty, Howard R. Youse, and A. T. Guard, Chairman. 

The nominating committee (Harry G. Day, Chairman, A. T. Guard, 
and Frank A. Guthrie) presented the following slate of candidates for 
office — For President-elect, William B. Hopp. For Treasurer 
(1972-75), Clyde R. Metz. For Trustee of the Academy Foundation, 
Damian Schmelz. For Bonding Committee, Robert Brooker and John A. 
Ricketts. For Research Grants Committee (1972-76), Kenneth E. 
Nichols. A. T. Guard moved that these men be nominated and that we 
cast a unanimous ballot for their election. Seconded and carried. 

Samuel Postlethwait presented a study of his methods of teaching 
botany, entitled, "Individualized Study for Today's Student." It was 
thought-provoking for all teachers, and well illustrated by movies and 
still photographs. 

The meeting adjourned, on motion, at 9:15 PM. 

Approved April 28, 1972. 

Respectfully submitted, 
J. Dan Webster, Secretary

NOTES 

Membership Dues — According to the Treasurer's records, the current status may be 
summarized as follows : 892 paid, emeritus, life, and honorary members and clubs ; 
105 on file from 1970 but not yet paid for 1971 ; 15 resigned or lost by 
reason of no current address ; 5 deceased during this year ; 103 new members 
(last ones to begin during 1972) ; 6 previous members reinstated during the year. 

Our attorney has confirmed that we may increase dues during 1972 according to 
Phase II legislation. Accordingly : $6.00 regular and high school club memberships ; 

$3.00 student membership ; $8.00 family membership ; $1.00 initiation fee for regular, 
club, and student ; $2.00 initiation fee for family. 

Interest — The Treasurer, from the total assets of both Academy and Administered 
Accounts, has maintained sufficient funds in the checking account to pay current 

bills throughout the year ; the remainder has been invested in savings certificates : 
Certificates redeemed during 1971. 1) $10,000.00 invested at 5.25% February 1971; 
September 1971 redeemption value $10,324.81. 2) $5,000.00 invested at 5.25% April 
1971; September 1971 redeemption value $5,139.09. 3) $5,000.00 invested at 5.75% 
February 1971; December 1971 redeemption value $5,185.29. 

Certificates current: 1) $10,000.00 invested at 6.00% April 1970; current value 
$10,941.86; maturity April 1972. 2) $5,000.00 invested at 5.75% April 1971; current 
value $5,205.39; maturity April 1972. 3) $4,465.07 invested at 5.75% April 1970; 
current value $4,938.07; maturity March 1973. 4) $6,000.00 invested at 6.00% April 
1970; current value $6,664.73; maturity March 1973. 5) $5,000.00 invested at 5.75% 
October 1971 ; current value $5,061.87 ; maturity October 1972. 

Treasurer — Expenditure exceeded budget mainly due to considerable amount of xeroxing 
materials and telephone calls relative to work with the attorney on tax status 
problems. 

Program Committee — Expenditure exceeded budget due to some 1970 bills which arrived 
months late. 

Newsletter — Expenditure exceeded budget this first year for the newsletter. Next 
year's budget has been increased. 

Reprints — Volumes 78 & 79 appeared in 1970. Payments by authors were not 
completed until this year; this account showed a deficit in 1970; net profit to 
the Academy = $572.54. 

Volume 80 appeared this year. Currently more than one third still owe for reprints. 
Anticipated profit = $125.00. 

The profit to the Academy pays for office expenses in billing and the expense for 
President's address, necrology report, and instructions for contributors. 

Attorney Fees — ICE, MILLER, DONADIO & RYAN of Indianapolis have been repre- 
senting us in clarifying our tax-exemption status. One additional quarterly 
billing can be expected in 1972. Although IRS has not completed study of 
documents and has not sent formal ruling, the attorney has instructed us to continue 
operating under the assumption of a final favorable determination. 

The 1972 budget allows for contracting a CPA firm to prepare the Indiana and 
Federal Non-Profit Organization Tax Forms and to perform an informal audit of 
the Treasurer's records. 

Science Talent— Refunds of $67.50 from the director and $16.00 from Scientific 
American have not been entered in this report as either income or expenditure. 

Science Fairs — A refund of $2,866.32 has been entered in this report as both income 
and expenditure. 

The unusually large expenditure is explained by $13,500.00 having been 
transferred to the Indiana Science Education Fund, Inc. 



Financial Report 21

NECROLOGY 

Fay Kenoyer Daily, Butler University 

(Samuel) Clifford Adams 

Rockville, Indiana Hanover, Indiana 

February 12, 1912 August 13, 1971 



Dr. (Samuel) Clifford Adams, a geology professor, was at his desk 
at Hanover College when he died August 13, 1971, of a heart 
attack. 

Born on a farm near Rockville, Indiana, February 12, 1912, Dr. 
Adams was of English descent. He graduated with a Bachelor of Arts 
Degree cum laude at Hanover College in 1935; obtained a Master of 
Science Degree (1940) and a Doctor of Philosophy Degree (1942) from 
the University of Iowa. He was an instructor of geology at Hanover 
College from 1935 to 1937, and clerk of mapping for the Agricultural 
Adjustment Agency, United States Department of Agriculture in 
Indiana from 1936 to 1937. He was an assistant at the University of 
Iowa from 1938 to 1942. He also served as Junior Geologist with the 
Soil Conservation Service, United States Department of Agriculture 
from 1939 to 1941, and field assistant for the Iowa Geological Survey 
in 1940. 

In 1942, he entered the United States Army and served until 1945. 
He was a combat intelligence officer and was permanently blinded by 
enemy mortar fire during the invasion of the Leyte Islands, the Philip- 
pines. For his heroism, he received the Combat Infantryman Medal, the 
Bronze Star and the Purple Heart. Posthumously, his wife received a 
certificate signed by President Nixon which states: "The United States 
honors the memory of Samuel C. Adams. This certificate is accorded 
by a grateful nation in recognition of devoted and selfless consecration 
to the service of our country." 

In September, 1945, Dr. Adams returned to Indiana to teach 
geology as an associate professor at Hanover College. Familiar with 
the campus from student days, he had little difficulty finding his way 
around, which he accomplished unassisted. An article in the magazine 
section of the Indianapolis Star (February 2, 1947) commended his 
classes. With the use of models, blackboard illustrations and free 
discussions, his classes maintained a high degree of interest. It was 
stated that he was the only professor in a Hoosier College, blinded in 
World War II actively engaged in teaching at that time. His wife, Mrs. 
Blanche Adams, also taught at Hanover College. They were both 
alumni of Hanover and she was a student at the University of Iowa at 
the same time as Dr. Adams. Clifford Adams was especially interested 
in soil erosion, recent stream and valley sedimentation, accelerated 

27 



28 Indiana Academy of Science 

sedimentation of the Galena River Valley, soil conservation, strati- 
graphy and sedimentation, general, surficial and structural geology 
and ground water. He became a full professor in 1951 serving the college 
with great distinction. 

Dr. Adams joined the Indiana Academy of Science in 1945 and was 
a Divisional Chairman of the Geology and Geography Section in 1953. 
He delivered a paper at that meeting on Modern Floodplain Deposits. 
In 1962, he gave a talk before the History of Science Section of the 
Indiana Academy of Science on A Century and a Quarter of Geology 
at Hanover College. The study of Hanover history was a hobby for Dr. 
Adams. He was also very interested in sports, particularly football and 
baseball. 

In addition to belonging to the Indiana Academy of Science, Dr. 
Adams was a Fellow of the Geological Society of America and belonged 
to the Geochemical Society, American Geophysical Union, Iowa 
Academy of Science, Sigma Xi, Delta Epsilon, Pi Gamma Mu, and was 
a charter member of the Indiana Section of the American Institute of 
Professional Geologists. He was awarded an alumni achievement award 
from Hanover College in 1967. 

Poised and sure, Dr. Clifford Adams faced a dark world with con- 
fidence and without self pity. He leaves with us the inspiration of an 
exemplary life. 

Herbert Faust Call 

Madison County, Florida Indianapolis, Indiana 

October 2, 1904 September 1, 1969 



Few practicing physicians have been a member of the Indiana 
Academy of Science, but Dr. Herbert Faust Call, a pediatrician, joined 
in 1935 because of a life long interest in natural science and because 
of his interest in archeology. These interests stemmed from early boys 
camp experiences and the collection of Indian relics and butterflies. He 
became a world traveler and a sportsman. On a "camera safari", Dr. 
Call and Katharine, his wife, visited eight national game preserves in 
East Africa in 1966. Then, they took their daughter Karen (now a 
pediatrician) and their son, William H. (an otolaryngologist) with 
them to the Fiji Islands, Australia and New Zealand in 1968. 

Born in Madison County, Florida, October 2, 1904, Dr. Call came 
to Indiana as a boy and attended grade and high school in Anderson, 
Indiana. He then attended Indiana University Medical School. He took 
his internship there and a residency at the James Whitcomb Riley 
Hospital for Children, receiving an M.D. Degree and his license to 
practice in Indiana in 1929. Post graduate work was done at Washington 
University at St. Louis, Missouri, and at the Children's Memorial 
Hospital in Chicago, Illinois. He opened his first office in Indianapolis 
in 1932 and developed one of the largest practices in pediatrics in 
Indiana.

Dr. Call was also a member of Sigma Chi Fraternity, Phi Rho 
Sigma, medical fraternity, Marion County Medical Society, the 
American Medical Association and the Woodstock Club. A good 
biographical account of Dr. Call appeared in the Indianapolis Star, 
September 2, 1969. 

Cancer was the cause of Dr. Call's death, September 1, 1969, 
bringing a busy, successful career to a close at only 65 years of age 
(lacking about a month). 




Dr. Ralph E. Cleland 

Distinguished Professor Emeritus of Botany 

Indiana University 



Le Claire, Iowa 
October 20, 1892 



Ralph Erskine Cleland 



Bloomington, Indiana 
June 11, 1971 



Dr. Ralph Erskine Cleland was a Distinguished Service Professor 
Emeritus at Indiana University when he suddenly died of a heart attack 



30 Indiana Academy of Science 

in his office June 11, 1971. He had gained international recognition for 
his study of the heredity and evolution of the evening primrose, 
Oenothera. 

Born in Le Claire, Iowa, October 20, 1892, Dr. Cleland was reared 
in Philadelphia. He attended the University of Philadelphia where he 
received an A.B. degree in 1915 with a major in the classics and 
history. During his junior year, a friend suggested that he take a course 
in botany. He was so interested that he became a botany major receiving 
an M.S. in 1916 and a Ph.D. in 1919. Reprints of his Ph.D. thesis on 
the red alga, Nemalion, were lost at sea. He received honorary degrees 
from the University of Pennsylvania, Hanover College and Indiana 
University. He served the United States in Italy during World War I 
from 1917 to 1918. 

He began his teaching career as Instructor of Biology at 
Gaucher College, Baltimore, Maryland, in 1919, and had become 
chairman of the department before leaving in 1938. He was an instructor 
at the Woods Hole Marine Laboratory in 1924, and a Guggenheim 
Fellow from 1927 to 1928 when he traveled to Germany to study. He 
had begun research on Oenothera while at Gaucher and had published 
a joint paper with A.F. Blakeslee in 1931 on analytical procedure in the 
study of genetic behavior in this genus and had begun to work out the 
probable evolutionary pathways in speciation. 

In 1938, he moved to Indiana University to become professor of 
botany and head of the department. In 1946, Dr. Cleland's research 
received further recognition and financial support as one of several 
participants in a 6-year program in the field of genetics financed by 
the Rockefeller Foundation and Indiana University. He became Dean 
of the Graduate School from 1950 to 1958 and Distinguished Service 
Professor in 1958. He retired in 1963 becoming Distinguished Service 
Professor Emeritus. He was co-director of the Indiana University 
Aerospace Research Applications Center from 1963 to 1967. 

Dr. Cleland joined the Indiana Academy of Science in 1938, the year 
he began teaching at Indiana University and was honored as a Fellow 
in 1940. Even though he was active in many other organizations both 
national and international, he devoted considerable time to our society 
and contributed many papers on Oenothera at the sectional meetings. 
He was a divisional chairman of the Botany Section in 1941, president 
in 1959 and served on many committees. Recently, he was active in 
planning the establishment and program of the Science and Society 
Committee. 

Dr. Cleland was a member of many other societies and received 
many honors and positions of responsibility from them. He served 
as editor-in-chief of the American Journal of Botany from 1940 to 1946 
and was president of the Botanical Society of America in 1947. He was 
awarded a certificate of merit as a distinguished botanist by that 
society "for his extensive researches into the species relationships and 
segmental interchange problems in Oenothera and also for his states- 
manship in representing plant science at the national level" (Golden 



Necrology 31 

Jubilee Volume of the Botanical Society of America, William Steere, 
Ed., McGraw-Hill Co., N.Y., 1958). 

He was a member of a group instrumental in forming the American 
Institute for Biological Sciences. While the Institute was still under 
the aegis of the National Academy of Science and National 
Research Council (1948 to 1949), he was a chairman in the society. He 
was chairman of the Division of Biology and Agriculture of the 
National Research Council from 1949 to 1952, editor of the section on 
plant cytology of Biological Abstracts 1925-. He was elected to the 
National Academy of Sciences in 1942; the Philosophical Society, which 
presented him with the Lewis Award in 1937, and he was Fellow of the 
American Academy. He was secretary of the Society of Naturalists from 
1938 to 1940 and president in 1942. He was president of the Genetics 
Society in 1956 and vice-president in 1954. He was a member of the 
Society of Study of Evolution and was vice-president (1953 to 1958) 
of the International Union of Biological Science. Dr. Cleland was 
starred in the American Men of Science and was the subject of 
numerous articles in newspapers, scientific journals and biographical 
publications. 

In 1960, Dr. Cleland and Dr. Farrington Daniels, vice-president of 
the National Academy of Science were "academic ambassadors of 
Science" on a visit to 11 Asian countries to meet with Asian leaders, 
both scientific and governmental, to discuss the possibilities of the 
development of these countries by science and technology. They 
planned to give a number of lectures to lay and professional groups 
on solar energy and plant genetics. 

In 1948, at a Paris meeting, the Committee of Science and 
Social Relations of the International Council of Scientific Unions dis- 
cussed science and the maintenance of peace. Questions were directed 
to the National Research Council Committee on UNESCO and Dr. 
Cleland was one of the persons replying to the request. He said 
{Science and the Maintenance of Peace by Bart J. Bok, 1949. 
Science 109:131-137): "Most modern wars have been brought about as 
a result of economic pressures, based on the Malthusian principle. Only 
science can relieve the basis of these pressures. Scientific control of 
population, the production of more efficient crop plants and domestic 
animals, the proper exploitation of vast areas of potentially usable land, 
control of soil erosion, development of irrigation and other projects 
designed to increase arable land, the discovery of new sources of 
energy — these are activities which will remove the chief cause of war. 
Without such activities, no amount of talk or education will achieve 
lasting peace." 

While chairman of the botany department and dean of the graduate 
school at Indiana University, Dr. Cleland and his wife were guests at 
the first state dinner to which leading scientists were invited by 
President and Mrs. Eisenhower. 

Dr. Cleland was the subject of an interesting article in The 
Indianapolis Star Magazine (May 13, 1962). After describing Dr. 



32 Indiana Academy of Science 

Cleland's scientific achievements, the author wrote: "One gets the im- 
pression in talking with this great scientist that primroses must have 
a tranquilizing influence, for Professor Cleland's calm and gentle 
manner gives no hint of his abilities as a dynamic, efficient 
administrator." Then later he wrote: "Professor Cleland is a deeply 
religious man. He holds that there is no true conflict between science 
and religion. 'Both science and religion', he says, 'have the same goal; 
that is the finding of truth.' " 

Dr. Cleland was quite active until death. One would invariably find 
him in attendance and often in a place of honor at national and 
international botanical meetings. He had just sent the manuscript to 
the publisher for his new book, Oenothera Cytogenetics and Evolution, 
dedicated to his wife, Elizabeth. Three sons are also scientists. They 
are William W. Cleland, professor of biochemistry at the University 
of Wisconsin, Robert Erskine Cleland, professor of botany at the 
University of Wisconsin and Charles F. Cleland, assistant professor 
of biology at Harvard University. A brother, Dr. James W. Cleland, 
is a Philadelphia pediatrician. 

The Indiana Academy of Science lost a great friend and valuable 
member with the death of Dr. Ralph E. Cleland. 



C(lare) F(rancis) Cox 

Hudson, Illinois Indianapolis, Indiana 

March 9, 1888 February 24, 1971 



Dr. Clare Francis Cox considered secondary education as the most 
stimulating professional field, because of the opportunity to encourage 
young people to develop an interest in science and specifically, 
ecology. He taught at Arsenal Technical High School in Indianapolis, 
Indiana, from 1917 to 1958, becoming head of the botany department 
in 1931. After he retired, an annual science award was established in 
his name in appreciation of his services. 

With Milo H. Stuart, he was influential in establishing a nature 
preserve at Tech (part of the campus later replaced by a school) and 
he sponsored a nature study group there for many years. He was active 
in the Indiana Nature Study Club. He also taught Microbiology at the 
Indiana College of Mortuary Science 1958 and 1959. 

Dr. Cox was born in Hudson, Illinois, March 9, 1888, and attended 
a country elementary school. He rode horseback to high school in 
Vandalia, Illinois. His teaching career began in a country elementary 
school the year after graduating from high school. He attributed his 
knowledge of birds, wildflowers and trees to his country boyhood 
rambles and curiosity. He also taught high school and was a basketball 
coach from 1913 to 1916 teaching at Herrin, Illinois, and Marion, 
Illinois. 



Necrology 33 

He began his college education during this period, too, receiving 
a Bachelor of Arts Degree from Illinois State University in 1917. 
Immediately afterwards, he started teaching at Arsenal Technical High 
School and also served in the United States of America Air Force 
Reserve from 1917 to 1919. 

A Doctor of Philosophy Degree was obtained at Chicago University 
in 1931. The influence of John Merle Coulter, while he was there, 
further stimulated his interest in science. Also, summer field trips in 
Utah and Colorado taught by Dr. Henry Cowles and Dr. George D. 
Fuller influenced Dr. Cox to study ecology and alpine vegetation. He 
became known here and abroad as an authority in this field. For three 
summers he and his wife established headquarters at 12,000 ft 
elevation near James Park, Colorado, in an abandoned gold miner's 
shack and explored the surrounding peaks for alpine plants. Tolland, 
14 miles away, was their supply base to which they hiked every week 
climbing 3,000 feet to reach it. 

Dr. Cox joined the Indiana Academy of Science in 1922 and was 
honored by being elected to Fellow in 1935. He served on the Junior 
Academy of Science Committee in 1939, 1940 and 1941. He also wrote 
a memorial to Emerson Blane Wright for the Necrology Report for 1928 
(Proceedings, V. 38, 1929). 

Dr. Cox was also a member of the American Association for the 
Advancement of Science, Ecological Society of America and was elected 
to Sigma Xi at Chicago University where he held a Coulter Fellowship 
for one year. He was life deacon at the Woodruff Place Baptist Church. 
Dr. Cox is listed in American Men of Science and Indiana Scientists. 
He has a son, Dr. Milton D. Cox, teaching at Miami University. 

Dr. Clare F. Cox died February 24, 1971, at 82 years of age. He had 
lived a full life, but considered his personal influence on his pupils and 
their enthusiastic response to his teaching as his greatest satisfaction. 
This is the ultimate reward for the dedicated teacher. 



G(eorg) K(arl) Neumann 

Hamburg, Germany Bloomington, Indiana 

June 6, 1907 April 13, 1971 



The practical application of many academic scientific research 
activities is obscure, but this was not so with the work of Dr. Georg 
K. Neumann. Widely known for his knowledge of the physical character- 
istics of human skeletons, Dr. Neumann was a consultant to the 
Indiana and Illinois state police departments in identification of 
unknown persons. In an Indianapolis News story (April 2, 1952) some 
of the more famous murder trials in which he had testified were dis- 
cussed. It was astonishing that a bit of bone, even a charred bone, could 
reveal the sex, age, size and region of ancestry of the deceased. Dr. 



34 Indiana Academy of Science 

Neumann was an associate professor of anthropology at Indiana Uni- 
versity and an archeologist. He had written two books and a book 
chapter relative to these subjects. He had participated in many Indian 
site excavations and was an authority on American Indians, their 
physical types, racial differentials and racial history. 

Born in Hamburg, Germany, June 6, 1907, Dr. Neumann received 
his higher education in America obtaining a Ph.B. degree in 1930, an 
A.M. in 1936 and a Ph.D. in 1943 from the University of 
Chicago. He taught at the University of Chicago, Western Reserve 
University and was assistant director of the University of Tennessee 
archeological projects. He left the museum of anthropology at the 
University of Michigan to become an assistant professor of 
anthropology at Indiana University in 1942. 

Dr. Neumann also became a member of the Indiana Academy of 
Science that same year, 1942, and was honored as a Fellow in 1957. He 
was a popular chairman of the Anthropology Section having served in 
1943, 1944, 1949, 1956 and 1959. He was to have served again in 1971. 
He presented numerous papers at Academy meetings concerning Indian 
physical types, racial affiliations, migrations and culture. He had served 
a number of years on the Fellows Committee and was a member at his 
death. Dr. Neumann also belonged to the Central States Anthropological 
Association, of which he had been president; to Phi Beta Kappa, honor 
society; and to the Mexican and German Societies of Anthropology. 

Not only were the macabre details of the murder trials in which 
Dr. Neumann testified newsworthy to reporters, but also the mysteries 
of aboriginal life determined by Dr. Neumann from the bones excavated 
from Indian mounds. Thus, several articles about his work in this field 
appeared also in Indianapolis newspapers. Some of these appeared in 
the Indianapolis Times (December 26, 1948), the Indianapolis Star 
(August 4, 1956) and Indianapolis News (April 2, 1952), and upon 
moving to Indiana University, his professional qualifications were dis- 
cussed in an article in the Indianapolis Star, February 7, 1942. 

Dr. Georg Karl Neumann died April 13, 1971, at only 63 years of 
age, when his unusual talent was lost to us prematurely. 



Claude E(dgar) O'Neal 

Coatesville, Indiana Delaware, Ohio 

January 29, 1884 February 8, 1971 



Dr. Claude Edgar O'Neal, botanist, died February 8, 1971. He had 
been a member of the Indiana Academy of Science since 1912, joining 
when a student working on a graduate degree at Indiana University. 
He gave a paper in 1914 on the species of Nummularia common in 
Indiana. Later, he became interested in the cytology of Datura and the 
embryologic development in Oenothera. 



Necrology 35 

Dr. O'Neal was a native of Coatesville, Indiana, born January 29, 
1884. He attended Indiana State Teacher's College in Terre Haute for 
4 years where he received a certificate. He then attended Indiana Uni- 
versity where he received an A.B. in 1911, was a teaching fellow 1912 
to 1913, obtained an A.M. in 1913 and a Ph.D. in botany in 1922. He was 
head of the Department of Science at Brazil (Indiana) High School; 
principal of the Coatesville (Indiana) High School and Hadley 
(Indiana) High School; and taught at Reno, Indiana. He became an in- 
structor at Ohio Wesleyan University in 1913 and served as head of 
the botany program until retirement. In 1920, he was named 
Professor of Botany on the Allen Trimble Foundation. He taught there 
until his retirement in 1954 when he became Professor Emeritus. He 
also taught one term after that from 1957 to 1958. In recognition of 
his service to Ohio Wesleyan University, the greenhouse adjacent to 
Bigelow-Rice Science Hall was dedicated as the Claude E. O'Neal Green- 
house in 1964. Former students and colleagues joined in this 
tribute. A memorial statement said, "The building housing the beauty 
and vitality of growing plants and, in its utilitarian function, serving 
his driving interest in botanical education, shall always stand as a 
fitting memorial." 

Besides his membership in the Indiana Academy of Science, Dr. 
O'Neal was a member of Phi Beta Kappa, Sigma Xi and Omicron Delta 
Kappa, honor socieites. He had been vice-president of the Botanical 
Section of the Ohio Academy of Science twice, and president of the Ohio 
Academy of Science from 1938 to 1939. He also belonged to the 
American Association for the Advancement of Science and Botanical 
Society of America. 

Although Dr. O'Neal had been in Ohio for many years, he kept in 
touch with former teachers, students and friends in Indiana. The high 
regard which they held for him was quite evident. His former students 
are too numerous to be mentioned, but hold many positions of honor 
and distinction as professors, department chairman, directors of 
research or heads of national botanical laboratories. Letters of love and 
gratitude from them to Claude and Mabel O'Neal were a great 
satisfaction. 



Milo Bostwick Sampson 

Erie, North Dakota Bloomington, Indiana 

June 18, 1908 April 10, 1971 



Dr. Milo B. Sampson was a professor of physics at Indiana Uni- 
versity and a leading authority on cyclotron design and operation. He 
was in charge of the development of a large cyclotron at Indiana Uni- 
versity when he died, April 10, 1971, at his home. He had received a 
grant from the National Science Foundation for this work. 

Born at Erie, North Dakota, June 18, 1908, Dr. Sampson went to 
the State College of Washington, where he received a Bachelor of 



36 Indiana Academy of Science 

Science Degree in 1931 and a Master of Science Degree in 1933. He was 
a Queen scholar and obtained a Doctor of Philosophy degree in physics 
at Princeton in 1937. 

Dr. Sampson was a physicist at the Biochemical Research Founda- 
tion of the Franklin Institute, Philadelphia, from 1937 to 1942. From 1942 
to 1943, he was research associate in the Office of Scientific Research 
and Development and the National Defense Research Committee at 
Princeton. From 1943 to 1944, he was physicist and section chief of the 
metallurgical laboratory, University of Chicago Laboratory, where the 
first nuclear reaction had been achieved in 1942. In 1944 to 1946, he was 
physicist at the Los Alamos Science Laboratory in New Mexico. In the 
atomic energy laboratories there, the atomic bomb was made. It was 
tested July 16, 1946, in the desert region just west of Sierra Oscura, 
about 50 miles northwest of Alamogordo. 

Dr. Sampson came to Indiana in 1946 as an assistant professor at 
Indiana University. He became associate professor in 1952 and professor 
in 1958. He was in charge of cyclotron research from 1946 on. The old 
cyclotron at Indiana University, which has been dismantled, was one 
of the first to be built in the country. 

Dr. Sampson joined the Indiana Academy of Science in 1967, and 
was author or co-author of a number of papers presented at sectional 
meetings before and after that date. These dealt, primarily, with the 
results from use of the cyclotron and the measurement of energy levels 
with a spectrometer. He was also a member of the American 
Physical Society, a member of Sigma Xi, scientific honorary society, 
Phi Kappa Phi and Pi Mu Epsilon. Biographical sketches can be found 
in American Men of Science, Indiana Scientists, and the Indiana 
University Alumni Magazine (1971, V. 33, No. 9, p. 40). 

Awesome nuclear power under the control of man, although 
devastating and controversial as an instrument of war, has undoubtedly 
saved more lives than it has taken because of these qualities. It is thus 
a deterrant to war between nations possessing it. Furthermore, with 
wise management, it is sure to find a prominent place as a peacetime 
power source. Radio isotopes have improved man's lot remarkably in 
the field of medicine. These accomplishments will stand as a tribute 
to physicists like Milo B. Sampson who were intelligent and resourceful 
enough to seek the truth about nuclear energy and how to control it.

Minicourses and the Audio-Tutorial System 

S. N. POSTLETHWAIT

Purdue University, Lafayette, Indiana 47907 

A student can select four variations of coffee from an ordinary 
vending machine, but when he enters the classroom he may receive in- 
struction identical to that of several hundred other students. It is an 
obvious fact of life that people exhibit great diversity, interests 
and capacities, yet our educational system is made up of large 
blocks of content (courses) with little or no provision to break the lock- 
step of time, content or instructional procedure. There is some justifica- 
tion for the classroom approach however, since education is not just 
a dispensing procedure and the teacher is vital to the learning process. 
Many people can trace their excitement about a specific subject to the 
special way the subject was presented by a great teacher. Unfortu- 
nately these "great teachers'' are rather rare and physical limitations 
permit only a few students to "sit at their feet." While it is true that 
the talent of these teachers has been made available to some degree 
through their writings, many good teachers never write for publication^ 
and even so, the limitation imposed by the printed word negates the 
potential of the teacher for the clever use of tangible objects and sound. 

Hopkins has suggested that the best learning situation is the 
"teacher on one end of the log and the student on the other." Hopkins 
assumed the teacher was a "good" teacher and, if one can assume the 
log was figurative, the concept serves as a proper model for the 
Audio-Tutorial (AT) system. The AT system used in conjunction with 
minicourses, while retaining compatability with the conventional edu- 
cational system, has great potential for providing students with im- 
proved access to "good" teachers and with some other important 
features such as greater individualization. This paper attempts to 
describe a pilot study currently being conducted at Purdue University. 

History of the AT System 

At Purdue University the author began an attempt to provide a 
remedial program in a freshman botany course in 1961. The initial effort 
involved the production of a weekly lecture on audio tape. This was soon 
expanded to include: 1) tangible objects (specimens, experimental 
equipment, models) ; 2) printed materials (texts, study guides, 
journal articles) ; and 3) projected images (slides and movies). Ultimately 
the program was produced by assembling the appropriate items ("logs") 
and, while sitting among these items, recording on audio tape the conver- 
sation one would expect to use with one student while tutoring the student 
through a sequence of learning activities. The product, i.e. the tape and 

45 



46 Indiana Academy of Science 

other materials, was then duplicated as many times as necessary to accom- 
modate all students. Because of student enthusiasm for the program the 
procedure was expanded to cover the content for the entire botany course. 
The course was then restructured to include three major study sessions: 

1) Independent Study Session (ISS) 

The audio tutorial program was placed in a learning center 
which was open from 7:30 am to 10:30 pm Monday through Fri- 
day. The student could come in at his convenience and check into a 
booth. On his way to the booth he would pick up a mimeographed 
sheet of objectives written in behavioral terms. Other components 
needed to complete the program (except for the student's own copy 
of the textbook and study guide) were housed in the booth. 
Materials too bulky or too expensive to include in each booth 
were placed on a central table for common use by all 
students.; The student placed the headphones in position and 
by listening to the tape, he experienced a simulated one- 
to-one tutoring by the instructor. The student could pace his study 
as he desired, stopping at any point in the program to use additional 
resources such as supplemental texts and discussions with the 
instructor on duty or with peers. Each student proceeded independ- 
ently of other students and was free to omit any part of the study 
unnecessary to help him achieve the stated objectives for the week. 
The prep room was equipped with a table, chairs and a coffee urn to 
encourage students to take frequent breaks and to enter into discus- 
sions with peers over a cup of coffee. When the student was satisfied 
with his progress he was free to leave without regard to scheduled 
class time. 

2) General Assembly Session (GAS) 

This session was scheduled on a weekly basis and included 300 
or more students. Activities in this assembly involved an occasional 
lecture, special films, major exams and other activities that could be 
done most effectively in a large group. Attendance was required only 
for certain special events. 

3) Integrated Quiz Session (IQS) 

This session involved eight students and an instructor scheduled 
to meet weekly for one-half hour. The primary purpose of the session 
was to exploit the principle that "one really learns a subject when 
one is required to teach it". For this session each student was expected 
to prepare a little lecture about each of the items (logs) used in the 
ISS. The instructor presented the items in the sequence programmed 
earlier and selected the student to lecture on a random basis. Thus 
all students were forced to organize the subject matter in their own 
minds and could not rely on superficial responses to instructor ques- 
tions. In addition, this session provided : 



Presidential Address 47 

1) direct feedback on the effectiveness of the components of the 
AT program; 

2) an opportunity for each student to know at least one instructor 
very well ; 

3 ) each student to be well known by at least one instructor ; and 

4) an opportunity to take care of certain administrative details. 

The AT system in this form has been adopted in a great many schools 
and in a broad spectrum of disciplines (one-third of the papers presented 
at the Second Annual Audio-Tutorial Conference held at Purdue in No- 
vember 1970 dealt with subject matter areas outside the field of biology 
and several were concerned with programs below the college level). 
Obviously, its effectiveness corresponds directly to the ability of the 
"good" teacher to prepare the AT programs and to originate the necessary 
supplementary sessions. Many teachers report highly successful systems 
(1,2,3). 

Minicourses and Mastery 

In 1969 when Dr. Robert N. Hurst joined the staff at Purdue Univer- 
sity with the assignment to convert a zoology course (Biology 109) to the 
Audio-Tutorial approach, it was decided to reorganize the content of both 
the zoology and botany courses into smaller units of information called 
minicourses. Each minicourse would cover a reasonably coherent segment 
of subject matter (topic) and each minicourse would have a written set 
of specific objects suitable for testing the student's mastery of the concepts 
included. No rigid guide lines were established as to length or teaching 
strategy. Primarily, the limits of a minicourse were determined by good 
judgment much as one decides on how to divide a book into chapters. 
Approximately 30 minicourses were identified for each course and several 
of these minicourses covered subjects common to both zoology and botany. 
It was clear that if students were required to master the objectives in their 
first study of the common minicourses it would be redundant to involve 
them with the same subject matter a second time in the subsequent course. 

As each student mastered the objectives for a particular common 
minicourse, it was recorded on his individual card and he was not required 
to repeat the minicourse study again. Thus, students entering the two 
course sequence through either botany or zoology and taking the common 
minicourse during their first enrollment accumulated some time which 
could be devoted to the exploration of their own interests through the study 
of optional minicourses during the second semester of their enrollment. 
The botany and zoology courses which had previously been two distinct 
four credit hour courses now became a "pool" of minicourses divided into 
four categories, i.e., 

1) Plant minicourses 3) Common minicourses 

2) Animal minicourses 4) Optional minicourses 



48 Indiana Academy of Science 

Students entering the botany-zoology complex by the way of botany were 
required to take the plant minicourses and common minicourses and those 
students entering the complex by way of zoology were required to take 
the animal minicourses and common minicourses. Optional minicourses 
were selected by the student during the second semester of enrollment 
as needed to complete the requirement for the full four credit hours in 
botany and four credit hours in zoology. 

Most of the objectives for each minicourse were written at the 
knowledge and comprehension level, and when a student achieved mastery 
for a given minicourse he had a C entered on his record for that minicourse. 
After completing the required number of minicourses at this level, the 
student was awarded a grade of C in the course for which he was enrolled, 
A student who had not completed the number of minicourses required for 
the course for which he was enrolled was given a grade of incomplete with 
the opportunity to complete the uncompleted minicourses during the subse- 
quent semester. At that time, the incomplete would be removed and a 
permanent grade would be assigned by the Registrar's office. 

Students who wished to earn grades of A or B could do so by 
completing additional activities requiring a greater knowledge and "under- 
standing" of science, a greater time imput and more creative ability. The 
A-B activities were administered on a point basis. Students receiving an 
A were expected to acquire 110 points, while those working for a B had 
to acquire 85 points. These points were earned by participating in a variety 
of activities including special examinations, outside readings, research 
projects, peer tutoring activities, library projects, and other ways agreed 
upon between the student and instructor. 

After two years experience it is clear that it is possible to combine 
the Audio-Tutorial system with the concepts of minicourses and mastery 
to develop a learning system which provides a great deal more individual- 
ization and flexibility than the conventional lecture-laboratory approach. 

Some advantages and disadvantages 

A partial list of advantages is as follows : 

1) The primary learning program (AT) can be prepared by a "good" 
teacher and all his skill in selecting and sequencing learning 
activities can be made available to each student on a simulated 
tutorial basis. 

2) The rate and emphasis of study is directly under the student's 
control. He can stop at any point in the program to obtain outside 
assistance (instructor, peer, book or other resources) and can 
repeat or skip any segment of the program appropriate to his 
needs. 

3) The system is designed for success. The expectation is that all 
students will achieve the objectives of each minicourse. The 
relatively small units of subject matter are less forboding than 



Presidential Address 49 

a complete course and a sense of accomplishment is achieved with 
the mastery of each minicourse. 

4) There is great flexibility for individualizing course content to 
the specific needs of students. Minicourses can be selected and 
combined in a variety of ways to accommodate major goals, inter- 
ests, capacities and backgrounds. 

5) Redundancy can be reduced and efficient use of facilities, staff 
and student time can be achieved. 

6) Selection of media and instructional strategy is limited only by 
the creativity of the instructor and his facilities. The nature of 
the subject matter and objectives dictate the procedure and 
materials to be used. 

7) Programs that only involve portable tangible items could be made 
available outside the Learning Center. Perhaps several mini- 
courses constituting a relatively high proportion of a regular 
course could be studied at home and thus reduce the cost to both 
the student and the school. 

8) The transfer of materials between courses and between schools 
could be accomplished more readily since each minicourse is 
essentially an independent learning system and could be easily 
combined with others to adapt to the local situation. 

A partial list of disadvantages is as follows : 

1) The development and testing of an AT minicourse program Is 
time consuming and requires considerable skill and talent. 

2) The system requires some psychological adjustment for both 
student and teacher. The student must assume a greater degree 
of responsibility for his own progress and make some decisions 
for himself. The teacher must become committed to "helping 
students learn" and accept less focus on himself and his role in 
the learning process. The teacher further must adjust to having 
all his efforts and objectives exposed to students and colleagues 
for review and criticism. 

3) Many factors only tangentially related to the system may be 
frustrating and create unexpected difficulties which have undue 
influence on the success of the program. A change from the 
routine within routine surroundings is never easy. 

Summary 

Although the pilot study using the AT system with minicourses and 
mastery concepts has been underway only two years, it is apparent that 
it is feasible and practical even in a conventional university setting. Its 
potential for individualization is well received by students, and the admin- 



50 Indiana Academy of Science 

istration of the program can be accomplished by re-deploying about the 
same number of staff as required for conventional teaching. 

The author's hopes for the botany and zoology students have nearly 
all been realized. Perhaps more important, however, is the potential the 
minicourse concept has for providing new ways of "going to college" and 
for assisting with equal opportunity education and continuing education. 
Alternatives to the existing educational system are necessary to accommo- 
date the needs of a substantial portion of our population. Many of these 
people are unable to fit into the regime of "going to school" for a variety 
of reasons, but they still have a need and desire of expanding their educa- 
tion. Self-instructional minicourses in the format described in this paper 
can provide the necessary flexibility and portability with no compromise 
in the quality of instruction. The compatibility of the system with 
conventional procedures makes it feasible to intermix the two ap- 
proaches with no loss or problem to the student. The major task now is 
to produce the quantity and quality minicourses necessary to accommo- 
date the current needs and to devise the additional administrative pro- 
cedures required to make such programs available on a broad scale.

The Role of Scientists in the Preparation and Evaluation of 
Environmental Impact Statements 1 

Alton A. Lindsey 2 

Department of Biological Sciences 

Purdue University, Lafayette, Indiana 47907 

Pressure from private citizens including many environmental 
scientists has prompted Congress, the Administration and the Courts to 
improve our national policies toward the environment during 1969-1971. 
The Congressional Research Service identified as "environment oriented" 
121 of the 695 bills signed into law during the 91st Congress. Signing of 
the National Environmental Policy Act (NEPA) on January 1, 1970, was 
President Nixon's first official action in the "environmental decade of the 
'70 's." The Act set up a 3-man Council on Environmental Quality (CEQ) 
with a small staff. It deals with environment broadly, whereas the Environ- 
mental Protection Agency (EPA), born on December 2, 1970, is concerned 
only with air and water pollution, environmental impact of pesticides, solid 
waste and radiation hazards in the general environment. As an operating 
agency, EPA received nearly $2.5 billion for F.Y. 1972. 

NEPA requires for major federal projects that the lead agency 
prepare a "draft" environmental impact statement, stating the effect the 
proposed action would have on the environment, including unavoidable 
adverse effects, possible alternatives, the long-term as well as immediate 
impact and any irreversible and irretrievable commitments of resources. 
The draft statement must be available to the public for 90 days before 
action is taken. Public hearings are to be provided "when appropriate" 
which presumably means in controversial cases. Draft statements are 
reviewed in the 10 regional offices of EPA, and by other involved federal 
agencies. The public (including outside scientists) is invited to make 
significant inputs into revision of draft statements, and thus into federal 
decision-making. This concedes that the public has some expertise as to 
what is in the public interest. As a panel of 3 federal judges ruled, "The 
very purpose of NEPA was to tell federal agencies that environmental 
protection is as much a part of their responsibility as is protection and 
promotion of the industries they regulate". 



1 The Indiana Academy of Science established in 1971 a Science Communication 
Award of $500., funded through the Science and Society Committee from its National 
Science Foundation grant. The award is presented at the general session of the fall 
meeting, when the recipient is called upon to give an address. He is also scheduled for 
visits to Indiana college campuses, to bring somewhat similar material to students, 
faculties and townspeople. Printed here is Dr. Lindsey's brief summary of his address 
given at the Earlham College meeting of the Academy on October 29, 1971. A more 
popularized version entitled "People, science and federal environmental policy" was 
given later at 5 colleges.

States should license the ecological consulting firms which are spring- 
ing up, so as to insure at least minimum qualifications. So far, these firms 
have had little business involving impact statements. There is much 
scientific and technical content in the areas under CEQ jurisdiction: air 
quality, weather modification, energy, hazardous substances including 
pesticides and herbicides, land use and management, noise, physiological 
health and human well-being (including food purity and waste systems), 
transportation, urban environments, water and wildlife. The Washington 
office of CEQ evaluates the final statements, chiefly by attorneys with 
some ad hoc reference to scientists. The Chicago regional office of EPA, 
one of the best, employs many technical experts, but has twice as many 
people trained in law and social science as in chemistry and chemical 
engineering. (Although EPA is often thought of as an enforcement agency, 
it is not empowered to take cases to court, but recommends action by 
prosecutors up to the Department of Justice.) A maxim in Washington 
says that scientists should not be on top, only on tap. But we think the tap 
should be turned on more often. This would make it less necessary for 
scientists' groups like Environmental Defense Fund to engage in litigation. 
Students being trained in the new environmental law specialty should take 
more courses in science. 

The federal projects that have been pushed through without compli- 
ance with NEPA have mostly been military procurement projects. Several 
large public works projects have been postponed by citizen action in federal 
courts for lack of environmental impact statements. However, no projects 
have yet been finally vetoed or terminated, without court action by private 
groups, because an impact statement projected environmental harm. 
Nationally, about 1,800 impact statements have been received, for Indi- 
ana only four. Apparently, only one public hearing on an impact state- 
ment has been held in the nation. Scientists Institute for Public Infor- 
mation is asking the courts to require AEC to prepare, for comment and 
discussion of alternatives, a detailed statement on the environmental 
effects of, not one reactor at a time, but a nation full of liquid metal fast 
breeder reactors. 

Since even the best impact statements prepared by the promoting 
agency are slanted toward advocacy, such statements for potentially 
controversial projects, at least, should be done by multidisciplinary teams 
independent of the agency, and using a broad systems analysis approach. 

The provisions of NEPA have greatly enlarged the opportunity of 
scientists, as well as the so-called ordinary citizen, to participate directly 
in the operative processes of government. For this unprecedented and 
superb mechanism of environmental democracy to start operating as 
Congress intended, it will require more understanding and activism by 
outside scientists and other private citizens.

A Brief Synthesis of Indiana Prehistory. B. K. Swartz, Jr., Depart- 
ment of Anthropology, Ball State University, Muncie, Indiana 47306. — — 
Indiana was subdivided into three physiographic zones, Moraine and Lake, 
Tipton Till Plain, and Valley and Upland, and its prehistory was examined 
on this backdrop through six developmental stages, Lithic (usually termed 
Paleo-Indian in North American archaeology), Archaic, "Intermediate" 
(a provisional stage specifically formulated from an Indiana point of 
view), Woodland, Mississippian, and Woodland-Mississippian (a fusion of 
the two preceding, rather than a stage in itself.) 

A Second Report on Earthwork Seven, the New Castle Site, a Portion of 
the Southeast Quadrant— 1971. Gary M. Heathcote, Yasuo Toyoda, and 
B. K. Swartz, Jr., Department of Anthropology, Ball State University, 
Muncie, Indiana 47306.— — Earthwork 7, Hn-1 (IAS-BSU), is a small 
"sacred enclosure" located on the southern periphery of the New Castle 
Site complex. Descriptively, the earthwork is a low-lying natural knoll, 
measuring 67 feet by 81 feet, surrounded by an aboriginally excavated 
interior ditch. Excavations in the southeast quadrant this year revealed 
the presence of plain Woodland Ware sherds within the disturbed fill strata 
of the interior ditch. No diagnostic features, such as post molds, were 
discovered, and only one lithic artifact, a pecked stone ball, was found 
in situ within the earthwork. 

Continued Excavation of Earthwork Four, New Castle Site, Indiana. 

Harold G. Stacy and B. K. Swartz, Jr., Department of Anthro- 
pology, Ball State University, Muncie, Indiana 47306. For the past 

6 years excavation has been carried on a panduriform mound known as 
Earthwork Four. This year the major portion of the northeast quadrant 
of the east mound was excavated. A total of 15 features were uncovered 
in the 39 5x5 foot excavation units excavated during the 1971 Summer 
Field School. These included three human cremations, one probable post 
hole, one unique soil formation, a bird burial, four ash and charcoal lenses, 
one group of rocks surrounding a piece of red ocher, two fire hearths (one 
with post holes), and two features of fire cracked rocks. During the excava- 
tion six scrapers, five pieces of nondescript pottery, two cores, three points, 
and a post hole filler from Feature 2 were unearthed. A rusted piece of 
metal and a square nail were found 48 inches below the surface in units 
N1-E3 and N2-E3, and another piece of rusted metal was found at the base 
of the mound in unit S1-E3. Also in unit S1-E3 the unexcavated portion 
of a cremation was uncovered. A portion of this earthwork had been exca- 
vated, possibly Redding's work in 1890.

Aerial Photography in Archaeological Survey. Robert E. Pace, Department 
of Anthropology, Indiana State University, Terre Haute, Indiana 47809. 

Where extensive areas are to be searched for archaeological sites, 

carefully planned and executed aerial photography lends invaluable assist- 
ance. While aerial film will record a few obvious sites, its greatest value 
lies in identifying relationships of surface natural features, land-use pat- 
terns, and back-road networks. With this information and topographic 
maps, surface survey can proceed more rapidly and efficiently. At specific 
sites, aerial film may record evidence of archaeological features not 
apparent to the surface observer. 

Archeology of Tell Hesban, Jordan. Robert Little, Department of 

Anthropology, Indiana University, Bloomington 47401. Tell Hesban, 

or ancient Heshbon, is a city mound at the edge of the plain of Moab in 
the Hashemite Kingdom of Jordan. It has an elevation of 895 meters above 
sea level and is 26 road kilometers southwest of the capital city of Amman. 
It is 30 kilometers east of the north end of the Dead Sea. 

The first time it is mentioned in history, it was a Moabite city, then 
a capital city of the Amorites of the Late Bronze Age. 

It was continuously occupied from that point by Isralies, Greeks, 
Romans, Christians, and Arabs. It was last mentioned by Arab writers 
in the 14 century a.d. 

The first expedition to Heshbon, sponsored by American Schools of 
Oriental Research and staffed by 45 technicians and 165 native workers 
was scheduled in 1967 but had to be canceled. There was 8 successful 
weeks in 1968, then canceled again in 1970, and another successful 8 
weeks in 1971. 

Much material has been recovered and analyzed, but since the second 
season has only reached Iron III and possibly II and in only some of the 
areas, it is too early for final conclusions. About 5 more seasons will be 
needed to develop a clear picture of 4,000 or more years of continuous 
history at one location. 

The Commissary Site: A Woodland Cemetery. Glory K. Houck and B. 
K. Swartz, Jr., Department of Anthropology, Ball State University, 

Muncie, Indiana 47306. Concentrated effort was made to discover 

a burial left in 1968 that would allow the reconstruction of the grid system 
established in 1966. Stakes from the original grid and a burial correspond- 
ing to the 1968 provenience were exposed; but, the missing lower limbs 
of the burial and its closeness to the edge of the site cause doubt that it 
is the 1968 burial. 

A total of 13 individuals in 9 designated burials were exposed and 
removed. Five individuals were removed from one unit alone. The possible 
1968 burial was associated with a great number of artifacts, including 
beaver incisors, worked chert objects, bear canines, antler tines, a tortoise 
shell rattle, and the remains of what may have been a "medicine bag/' In

association with another individual in the same excavation unit were an 
expanded stem elbow pipe of steatite and two shouldered knives. 

The Henry County district soil scientist identified the dark brown 
soil surrounding burials as gravelly silt loam, identical in texture to the 
soil found in the valleys of the Big Blue and Little Blue Rivers. In his 
opinion, the normal subsoil of the site had been removed and replaced with 
the soil transported from the valley beds. 

Special emphasis was placed on stratigraphy and outlining of burial 
pits. 



Bone Growth in Two Prehistoric Indian Populations 

Anthony J. Perzigian

University of Cincinnati, Cincinnati, Ohio 45221 

Abstract 

The diameter of the adult radius was compared in two prehistoric Indian popu- 
lations which differed markedly in diet. The Indian Knoll population of the Archaic 
Period was a hunting and gathering group. The Pete Klunk Mound Group population 
of the Middle Woodland or Hopewell Period supplemented its hunting and gathering 
with part-time agriculture. Therefore, the diet of the Hopewell population was larger 
and more varied than that of the Indian Knoll population. Statistically significant 
differences in radius diameter were shown to exist both inter- and intrapopulationally. 
Males of both populations were larger than females. Males and females of the Hopewell 
group were larger, respectively, than males and females of the Indian Knoll group. 
These population differences in bone diameter are attributed to differences in the 
aboriginal diets. 

The effect of nutrition on circumferential growth of the radius bone 
was examined in two prehistoric Indian populations, the Indian Knoll of 
Kentucky and the Pete Klunk-Hopewell of Illinois. The Indian Knoll pop- 
ulation (dated between 2500 and 2000 B.C.) represents the Archaic Period 
of Eastern United States prehistory. The subsistence activities of this 
group were centered exclusively around hunting and gathering in the 
vicinity of the Green River. The Hopewell, a more recent population (dated 
between 50 B.C. and 250 a.d.) represents the Middle Woodland Period. This 
group also relied on hunting and gathering but supplemented these 
activities with part-time agriculture in the Illinois River Valley. The 
hypothesis tested is that due to agriculture and, as a consequence, a larger 
and more varied diet, the amount of bone growth in the Hopewell popula- 
tion would be greater than that of the Indian Knoll population. 

Materials and Methods 

Only well-preserved, intact radii from adult males and females were 
studied. The sampled radii represented individuals ranging in age from 
20 to 70 years. The sample was made up of 121 males and 54 females from 
Indian Knoll and 45 males and 46 females from Hopewell. Those radii 
which evidenced obvious pathology such as periostitis or arthritis were not 
used. The width or diameter of each radius was measured at two sites: a 
cortical or compact bone site at a point one third the shaft length as meas- 
ured from the styloid process and a trabecular or spongy bone site, at a 
point one tenth the distance from the styloid process. A photon absorptio- 
metric technique developed by Cameron (1) was employed to measure both 
width and bone mineral content of each radius. A monoenergetic photon 
beam from a low energy radionuclide, iodine-125, was passed across the 
width of the bone. Changes of transmittance, which are directly propor- 
tional to the bone mineral mass in the scan path, were measured with a 
scintillation detector-pulse height analyzer system (3). Data from each 
scan or measurement were transferred to paper tape by means of an eight 
channel Tally Paper Tape Punch. An IBM Tape to Card Converter trans-

Results 

Table 1 presents data on the width of the radii used in this study. In 
all cases the average width of the Hopewell radius exceeds that of the 
Indian Knoll radius. This relationship is especially evident in the 14.5%

difference in average cortical width between the two female samples. In 
Table 2, Student's t-tests show that when Indian Knoll males are compared 
to Hopewell males or when Indian Knoll females are compared to Hope- 
well females, the differences in average radius width are very highly 
significant at the 0.001 level of confidence. Size differences are further 
indicated when the Hopewell females are compared to Indian Knoll males. 
No statistically significant difference between their respective cortical 
widths could be found despite a statistically significant sexual dimorphism 
within each population with males being larger than females (Table 2). 

Discussion 



In the earlier stated hypothesis, bone growth was predicted to be 
greater in the Hopewell population than in the Indian Knoll population. 
The data on radius width show this to be true. However, to fully test the 
hypothesis it must be shown that bone width and diet are related and that 
significant nutritional differences exist between the two populations. Garn 



Anthropology 61 

(2) has shown that bone width is related to caloric sufficiency to the extent 
that average bone diameter or width may be 15% narrower among the mal- 
nourished of a population. The data in Tables 1 and 2 are taken to indicate 
significant nutritional differences. 

The archaeological data also suggest nutritional differences. Excava- 
tion of the Indian Knoll site has categorically demonstrated that this popu- 
lation was pre-agricultural (8). Farming implements such as shell hoes 
and floral remains of domesticated species are absent. The remains of shell- 
fish and mollusca were found interspersed throughout the refuse or 
cultural debris of the site. The heavily forested area around the Green 
River provided the Indian Knoll people with a variety of foodstuffs. 
Remains of hickory nuts, walnuts, and acorns are reported by Webb (8) 
along with hammerstones which were employed to process the nuts. An 
abundance of deer, Odocoileus virginianus, indicates its importance as a 
meat source. In fact, of 27,756 animal fragments identified, 23,177 were 
from O. virginianus. Atlatls or spear throwers were found in association 
with burials and probably were used to kill both deer and wild turkey, 
Melaegris gallopavo. 

The Green River provided staples other than just mollusca, for fish 
were also a significant component of the diet. Webb (8) describes the deer 
ulnae and tibiae which were fashioned into fish hooks. Skeletal remains 
of the drumfish, Aplodinotus grunniens, were scattered throughout the 
debris of the midden. Migratory waterfowl such as the Canada goose, 
Branta canadensis, were also found. 

The Middle Woodland Period of North American prehistory emerged 
at least 2,000 years after occupation at Indian Knoll was terminated. The 
former Period, then, is represented by cultures which benefited from a 
longer experience adapting to the New World environments. The hunting 
and gathering society of Indian Knoll did not alter the normal habitats 
of the natural flora and fauna. As stated above, shellfish were merely 
gathered, nuts collected, and deer hunted. In contrast, the later Early 
Woodland cultures which antedate the Middle Woodland cultures actually 
modified the floral environment to their own advantage. Various excava- 
tions of Early Woodland sites have shown remains of plants not naturally 
indigenous to those areas. Archaeologists infer that the Indians intention- 
ally introduced species whose existence depended upon human manage- 
ment. This took the form of cultivation and selective removal of other 
plants which might have been competitors. These plants used by man are 
cultigens, the earliest of which were: Helianthus annuus, sunflower; Iva 
sp., marsh elder; Cucurbita pepo, squash; Lagenaria siceraia, gourd; and 
Chenopodium album, goosefoot or lamb's quarters. 

An Early Woodland Kentucky site near Indian Knoll has yielded 
human fecal material which reflects subsistence activities. Watson (7) 
reports that the feces at Salts Cave contained hickory, acorn, sunflower 
seeds, Chenopodium, and Iva. The latter three probably represent the 
earliest cultigens in this eastern woodlands area. Significant too were 
remains of two tropical exotic plants, squash and gourd. Cultivated plants 
made up 45% of the bulk of the Salts Cave feces. The intermediacy of 



62 Indiana Academy of Science 

this site relative to the Indian Knoll and Hopewell cultures has been 
shown by radiocarbon dates of 710 ± 200 B.C. 

The original stimulus to cultivate was probably a product of cultural 
diffusion from Mesoamerica where, for example, squash, gourd, and corn 
are indigenous. The adoption of incipient agriculture in the Early Woodland 
Period provided the Hopewellians of the Middle Woodland a tested, success- 
ful behavioral adaptation. The evidence is impressive that by Middle Wood- 
land times, horticulture had become widely practiced in both the Ohio and 
Mississippi River Valleys where it was to persist until contact times. 

The village site that adjoined the mounds which contained the 
Hopewell skeletons is today covered by a town and highway and therefore 
beyond archaeological recovery. Examination of other Middle Woodland 
sites can, however, provide a picture of Klunk-Hopewell subsistence 
activity. The McGraw site of Ross County, Ohio, is situated in the flat 
bottomland or flood plain of the Scioto River. Such riverine locations, even 
today, are the best areas for agriculture. Prufer (4) reports the discovery 
of a medium-sized ear of corn in the middle stratum of the site. One may 
posit, therefore, that, following in the tradition of the Early Woodland, 
Hopewellians were introducing and propagating alien plants. Prufer maxi- 
mizes the significance of the corn and believes that this community's 
primary economic activity was farming based on a shell hoe technology. 
Secondary activities in order of decreasing importance were shellfish 
collecting, hunting, and wild plant collecting. Prufer reasons that the 
nearby burial mounds, which are large in size and rich in material content, 
could have been built only with the support of a stable agricultural 
economy. 

Middle Woodland sites in Illinois have also yielded corn. Vickery (6) 
reports finds from the Jasper Newman site of Moultrie County (50 ± 140 
B.C.) and the Macoupin site of Jersey County. In Calhoun County where 
the Klunk-Hopewell site is located, the Peisker site (180 ± 130, 70 ± 120, 
250 ± 20 a.d.) and Ansell site (250 ± 150 A.D.) also contained 
corn. Both Illinois and Ohio Hopewell climates were capable of supporting 
the corn plant. 

Judging from the above village or occupation sites, one can cate- 
gorically state that Hopewellian Indians of the lower Illinois River Valley 
had expanded the exploitative potential of their environment through 
farming activities. This is not to say, though, that the Valley itself was 
not already naturally endowed with a diversity of food resources. Struever 
(5) has shown the easy availability and abundance of hickory nuts and 
acorns; Iva and Chenopodium; deer; geese and ducks; and fish. Both 
population density and residential stability increased during Hopewellian 
times. The number and size of burial mounds attest to the population 
increase while numerous storage pits and earth ovens in close association 
with a house at the Apple Creek site in Madison County, Illinois, attest 
to the residential stability. This increase in population density and resi- 
dential stability is taken to indicate the larger and more varied diet of the 
Hopewell people over that of their forebearers, the Archaic Indians of 
Indian Knoll. 



Anthropology 63 

The larger and more varied diet of the Hopewell people is considered 
to be the primary variable which accounts for their bone growth being 
greater than that of the Indian Knoll people who did not supplement their 
hunting and gathering with part-time agriculture. There is the possibility, 
though, that genetics is partly involved. The effective breeding size of the 
two populations was small. Inbreeding was therefore probably operating 
in both and contributing to an increase in homozygosity and decrease in 
overall genetic variability. Since Hopewell populations were larger and 
since they participated in an extensive trade network, outbreeding was 
probably more characteristic than in earlier Archaic times. If outbreeding 
were more common among Hopewellians, their larger bone diameter could 
be partly explained. For example, hybrid vigor in the form of increased 
stature has been observed among the offspring of outcrosses between 
European sailors and Polynesian women. This is not taken, however, to 
detract from the significant nutritional differences between the two 
populations. 

Conclusions 

1) The diet of a Middle Woodland-Hopewell population from the 
lower Illinois River Valley has been shown to differ from that of an 
Archaic population from the Green River in Kentucky. The latter popula- 
tion relied exclusively on hunting and gathering while the former enjoyed 
a larger and more varied diet due to the adoption of part-time agriculture 
to supplement hunting and gathering. 

2) Statistically significant differences in radius diameter or width 
were shown to exist both inter- and intrapopulationally. Males of both 
populations were larger than females. Males and females of the Hopewell 
group were larger, respectively, than males and females of the Indian 
Knoll-Archaic group. These population differences in bone diameter are 
attributed to differences in the aboriginal diets.

The McKinley Site 

Robert M. Little 

Andrews University 

Berrien Springs, Michigan 49103 

Abstract 

The McKinley Site is located just south of Noblesville, Hamilton County, Indiana. 
It was first discovered in 1937 when a road was widened. It was excavated by Downey 
Raibourn and Jack Householder, as a salvage operation, starting in 1953 under the 
direction of the late Glenn Black. 

The site had three periods of occupation from Late Archaic to Early Woodland 
and finally during the contact period of 200 years ago. In the Late Archaic there was 
evidence for hot-rock cooking plus an emphasis on small animal hunting and gathering. 
The tool inventory was more sophisticated than for later occupations. The Early Wood- 
land period emphasized larger animal hunting and there was evidence for pole structures. 
The surface and near-surface occupation included stone artifacts and tools as well as 
historical objects. Eighteen burials recovered showed associations with Indian Knoll. 

Introduction 

The McKinley Site, located just south of Noblesville in southeast 
Hamilton County, was a salvage operation, excavated as a result of Indiana 
State Highway operations. 

In 1937 the road leading to Noblesville from the south was a very 
narrow, paved highway. When the highway was widened, the road scrapers 
cut into the east bank of the river terrace just south of a house owned by 
Mr. and Mrs. McKinley. Bone fragments and flint chips were noticed by 
the highway crew, and Dr. Glenn A. Black, Indiana University, was noti- 
fied. He and Jack Householder examined the site and noted the situation. 
Householder visited the site a number of times as the years passed and 
collected samples from the surface. 

Downey Raibourn and Jack Householder began excavation of the 
McKinley Site on June 7, 1953. Of the total area dug, approximately half 
of the work (750 square feet) was finished in the first season to sterile 
soil, which in some cases went over 3 feet deep. In the next 2 seasons 
approximately 775 square feet of surface was excavated to sterile soil. 

The author wrote up the McKinley Site excavation as a thesis at the 
suggestion of Dr. James Kellar, as part of the program to finish the work 
of the late Dr. Glenn Black. 

Site Description 

The McKinley Site overlooks to the west, what is known as Horse 
Shoe Prairie which is a fertile, flat land formed by several sharp bends 
in the west fork of White River. In all probability during Late 
Archaic-Early Woodland times, the river bank came up to the terrace that 
is contiguous to the site. It has apparently been an ideal location for 
occupation since post-glacial times.

The area of the site had, in the immediate past, been in garden, but 
at the time excavation began, it was covered with broom grass, wild lettuce 
and weeds. The plow zone penetrated to at least the 0.4 foot level, but there 
was still much material on and near the surface. In this level were found 
bones of domesticated animals such as sheep and hog, glass and other arti- 
facts of both modern man and of early settlers. 

The area of occupation extended for 60 feet along a northeast- 
southwest line and roughly paralleled what had been the original bank 
of the river as it made its sharp bend forming the prairie. The road cut 
doubtless destroyed much of the site, but there is no estimate of how much. 
Unsuccessful attempts were made to locate material west of the right- 
of-way. The 60 lineal feet previously mentioned applied to the surface and 
to the layer down to the 1.6 foot level. The third occupational area was 
primarily limited to a more circular area of about 30 feet in diameter at 
the north end of the 60-foot line. 

Methods 

The site was laid out in 40 squares, each 10 feet by 10 feet. During 
the first season, excavation was continued to sterile soil on a 
10 foot block plan as originally intended. In addition, two 5-foot blocks 
were opened 50 feet north and 30 feet east of the center lines to establish 
the perimeter of the site. However, at the start of the second season the 
expedition was constantly hampered by after-hour pot hunters. For this 
reason, 5-foot squares were excavated and every effort was made to com- 
plete a square before opening another. This was not an ideal technique, 
and has led to many problems in studying the field notes, but was 
necessary procedure under the circumstances. 

In the laboratory, the author analyzed the projectile points for their 
discrete attributes under a formula worked out at the University of 
Michigan (1), as follows: outline of the blade, outline of the base, junc- 
tures of the haft element, presence or absence of a shoulder or a barb, 
outline of the shoulder element, tang form, tang outline-proximal 
segment. 

Of the 157 total selected points, 69 were complete enough for metric 
measurements. 

Results 

The stratigraphy of the site was not apparent at the time of the 
excavation, but analysis clearly indicated three occupations. On the 
surface, along with the modern debris, a few sherds of grit tempered cord 
marked pottery of Late Woodland variety were found. However, many 
of the projectile points in the same context were Archiac. Under this 
modern debris area which can be classified with the surface as Zone C,

a continuous black layer was noted over the entire site and was variously 
referred to in the field notes as black soil, black debris, black disturbed 
and mottled. It varied in thickness from several inches to 2 feet, and 
averaged about 1 foot. This fact seems to correlate well with the second 
occupation, or what was called Zone B. The extreme blackness of the second 
layer indicated an intense occupation. 

Under Zone B in discontinuous patches of about the same thickness 
was a lighter-colored occupation that was called yellow-disturbed by the 
excavators. This first occupation of the site was called Zone A. It is not 
as wide-spread as Zone B and was similar except for the presence of many 
shell fragments and a change in the style of the projectile points. Other 
artifacts of stone and bone also indicate a change of style. Below Zone A 
was a sterile yellow Miami silt loam soil. 

The chipped stone projectile points recovered at the McKinley Site 
were well distributed over the area. In all, some 363 points and fragments 
of points were recovered, but only 149 were complete enough for the 
discrete attribute analysis. The raw material was for the most part chert. 
Eight bone points were added to this analysis for a total under considera- 
tion of 157. Of this total, 64% were found on the surface, 24% in Zone B 
and 16% in Zone A, including the bone points.

My analysis revealed at least one new type of projectile point for each 
Zone. In Zone A, two distinct types were noted. All bone projectile points 
were found in this lowest zone, and were similar to those found at Indian 
Knoll (4). In the classification, they were described as having an ovate 
blade and a lateral-lateral haft element (also known as side-notched). A 
type originating (3) in Zone B was described as having an excurvate 
blade and straight shoulders. Only Zone C revealed triangle points with 
subconcave bases. 

The tool inventory was very extensive and was divided into two 
general categories, stone and bone (Table 1). Of special interest was the 
fragment of an atlatal hook, which was found at the lowest level. 
Atlatal hooks were known to have been used in the area during Late 
Archaic times (2). The bone material recovered was, for the most part, 
in good condition and quite extensive (Table 2). The bones and bone 
fragments from animals used for food. Included were disarticulated dog 
bone fragments found scattered throughout the site.

Of the 18 burials, there were 10 males, 5 females, and 3 infants. The 
age at time of death ranged from 13 to 51 for the males and from 30 to

Dr. Georg Neumann, and are very similar to Indian Knoll. However, the 
McKinley population lived longer on an average than the Indian Knoll 
population and were 1 to 4 inches taller. (Tables 3 and 4).

Discussion 



Other interesting features, in addition to burials, included pits and 
post holes. There appeared to be no consistency in the size and shape of 
the pits. There was no evidence for bark or rock lining for storage purposes 
although several small pits were found containing charred nuts. Other 
small pits contained charcoal and red burned clay. 

One special pattern found in the lowest level of occupation was noted 
by the excavators. At least six pits were uncovered with concentrations 
of rocks in the center. These pits ranged from 1 to 2 feet in diameter, and 
averaged a foot deep. In many instances these pits showed a possible 
flanged rim. The excavators indicated that this was evidence for "hot rock" 
cooking by the earliest occupants of the site. 

Because of the density of the occupation it was difficult to identify 
all of the post holes that were present. Some organization was present, 
e.g., a suggestion of a straight line in the southwest quadrant of the ex- 
cavation. The most intensive occupation appeared to be in the lowest strata 
of Zone B. The organization that was present in the post holes can probably 
be associated with the housing used primarily by the Zone B occupation. 

Conclusions 

It is obvious that hunting and gathering was the life style throughout 
the occupations of the site, and that the availability of the fauna was 
reasonably constant. However, there seemed to be an emphasis on small 
animals at the lowest level, and a corresponding emphasis on larger animal 
hunting in the middle occupational level. 

There seems little doubt that the earliest village in Hamilton County, 
Indiana, may well have been a small band of people, who left their home 
at Indian Knoll, Kentucky, and worked their way up the White River to 
settle at Horse Shoe Prairie sometime before 1000 B.C.

The Hybrid Origin of the Arikara Indians

Abstract 

The hypothesis of a hybrid origin of the historic Arikara of the Great Plains was 
examined by multivariate-discriminant computer analysis applied to samples of Arikara 
and related skeletal material. The ethnohistorical and archeological evidence bear- 
ing on the Arikara was summarized, and the skeletal material utilized was described. 
Three putative ancestral groupings were examined by F and t significance tests for 
cranial measurements and indices, and were subjected to multivariate analysis with 
Arikara sample series to determine their relationships. The initial hypothesis of the 
Arikara being closely related to the protohistoric and historic Pawnee, and less closely 
related to Siouan groups such as the Mandan and the Ponca and Omaha, was supported. 

The purpose of this study was to examine the hypothesis of a di- or 
tri-hybrid origin of some of the populations of the Great Plains, as initially 
advanced by the late G. K. Neumann in 1942 (5). This hypothesis was 
tested through the application of multivariate computer analysis. The 
Caddoan-speaking Arikara of South Dakota were utilized as an example. 
In their migration up the Missouri River, the Arikara came into contact 
with the Siouan-speaking peoples of the Middle Missouri Tradition. Despite 
the occasional war-like nature of the contacts, considerable mixture did 
occur, especially in the northernmost Arikara villages. Contacts of lesser 
importance may have been made with the Siouan bison hunters of the 
Dakota and Dhegiha divisions. Physically, the analysis primarily involved 
populations of the Muskogid and Dakotid varieties, following the termi- 
nology of Neumann (6). These groups include: 1) historic and protohistoric 
Pawnee represented by samples of the Upper Republican and Nebraska 
Culture aspects and historic Pawnee (Muskogid Ancestral Group) ; 2) a 
Plains Woodland and Mandan-like Siouan population (Dakotid A Ancestral 
Group) ; and 3) the possibility of significant contribution of a second type 
of the latter (Dakotid B Ancestral Group), represented by the Ponca and 
Omaha. It is to be understood that the term "putative ancestral group", 
particularly in the case of the Dakotid B Ancestral Group, does not infer 
direct descent, but rather the possibility of mixture through contact. It 
has long been suggested that the Arikara are descendants of the Pawnee 
(3, 9, 10, 11, 14). Most of the evidence for this is linguistic in nature. The 
history of the Arikara prior to the close of the 18th century is not perfectly 
known, and can only briefly be summarized here. Northernmost of the 
Caddoan-speaking people, the Arikara were the last of that linguistic stock 
to come in direct contact with white chroniclers. Archeologically, some 
time after circa a.d. 100, but still several centuries before the arrival of 
the first white men in the Central Plains region, the Middle Woodland- 
Hopewellian complexes were succeeded by a group of semi-horticultural 
pottery-making cultures implying a much more stable pattern of settle- 
ment. Included in these semi-sedentary complexes were several prehistoric 
manifestations featuring small loosely arranged unfortified settlements — 

71 



72 Indiana Academy of Science 

the Nebraska Aspect of northeastern Kansas and eastern Nebraska, and 
the Upper Republican Aspect of western Kansas and Nebraska (16). There 
is archeological evidence that the Arikara were established in present 
central South Dakota by the 15th century, as represented by the Initial 
Coalescent Variant (4). The Initial Coalescent sites appear to represent 
the first stage of an amalgamation of the Central Plains and Middle 
Missouri into the Coalescent Tradition. There is a considerable gap in the 
archeological record between the Upper Republican and Nebraska Cultures 
and the Pawnee, perhaps due to the dry years of the 1400's in the Central 
Plains. The close similarity in houses, pottery, and other artifacts between 
the Initial Coalescent and the Central Plains Tradition however leaves little 
doubt that the Initial Coalescent groups were immigrants from the Central 
Plains. Few studies in physical anthropology have been done on the remains 
from the Great Plains. Wedel (15) says of this area: "For various reasons 
it has remained one of the last major geographical provinces to attract 
the interest of trained students of prehistory — strange to say, despite the 
demonstrable richness of this upper Missouri region for the study of human 
prehistory, no comparable body of data correlating cultural and soma- 
tological materials on the Arikara — or for that matter on any of their 
neighbors — has yet been published". 

Crania of 169 nondeformed adult males comprise the 9 series used 
for the study. All of the crania were measured and examined by Georg 
K. Neumann, and the data placed in the files of the Laboratory of Bio- 
anthropology, Indiana University, prior to his death. The original data 
is now in the possession of his surviving family. The samples used are well- 
documented temporally, and are based on specimens whose cultural affili- 
ations are known either from archeological materials or historic records. 
Identical measurements and observations were employed in assessing each 
series ; error on the part of non-comparable data from different observers 
was eliminated. The samples represent the totality of available materials 
which adhere to the above criteria, and are considered adequate for estima- 
tions of the parameters of the actual populations involved. The question 
of the particular characteristics which are similar and different between 
the groups should hopefully be examined in light of what is known of the 
heritability of anthropometric traits. However, estimates which have been 
made show a considerable variability in results, depending on the methods 
used. Twin studies appear to show a fairly high agreement (12) in that 
certain traits such as stature, limb lengths, facial height, and the cephalic 
index appear to be highly heritable, having little within-pair variability 
among dizygous twins (1, 2, 7, 8, 13). Despite the claim that such studies 
show agreement among themselves (12), discrepancies do exist. Osborne 
and DeGeorge (7) find the cephalic index to have the highest heritability, 
while the same trait is listed as "unstable", inferring a low heritability, 
in Ostertag's study (8). In a study mentioned above (13), twins were com- 
pared in terms of 64 anthropometric traits, of which only 3 were not 
significant at or beyond the 0.05 level of probability. Of the remaining 
61 variables, all but 6 were significant at or beyond the 0.01 level. This 
implies that nearly all anthropometric traits have very significant herita- 
bility factors, while being little influenced by environment. However, the 
length of the left ear is significant at the 0.05 level, while the right ear 



Anthropology 73 

shows considerably more significance (p=0.01) between mono- and 
dizygous twins! Given such difficulties and inexplicable results, it would 
seem that heritability studies point to very different conclusions. Given 
also the questionable nature of mandibular traits due to developmental 
influences, these problems make it unwise, in the opinion of the author, 
to base any interpretation of the traits which emerge from the analysis 
on these grounds. 

The ancestral groupings were initially arrived at by an examination 
of the temporal, spatial, and apparent biological similarities of the series 
involved. Three statistical methods were used to substantiate this consoli- 
dation of the material, including analysis of similarities of qualitative 
variables, F tests of homogeneity of variance, and t tests for significant 
differences in means. Eighteen multivariate-discriminant functions were 
calculated, using all possible combinations of the ancestral groups with 
the two initial Arikara series and the pooled "tribal" Arikara series, for 
both measurements and indices. The initial separation of the total Arikara 
sample into two series, the Muskogid Arikara, and the Dakotid A Arikara 
(after the terminology of G. K. Neumann) was made for two reasons. The 
available information indicated that the skulls grouped as the Muskogid 
Arikara originated in earlier, more southerly sites where the population 
would be more likely to resemble the proposed original parental (Muskogid 
Ancestral Group) population, and that the Dakotid A Arikara skulls origi- 
nated in sites later in date and more northerly in the territory occupied 
by the Arikara, and would be more likely to resemble the groups contacted 
later in Arikara history (the Dakotid A Ancestral Group). Also an exami- 
nation of the material by the author and G. K. Neumann indicated that the 
samples were slightly different in morphological characteristics. The 
results of the initial multivariate functions appeared to bear out this con- 
tention. However, the differences between the Arikara samples was slight, 
and in the opinion of the author the total Arikara sample, or pooled "tribal" 
Arikara series was the best indicator of overall relationships. The final 
multivariate-discriminant functions which deal with this grouping are 
therefore considered to be the most applicable to the examination of the 
hypothesis, and are summarized here. 

The analysis indicated that the Arikara were most closely related to 
the Muskogid Ancestral Group, and that this similarity was greatest in 
the region of the cranial vault, both by size and by proportion. The overall 
conformation of the facial area was also very similar, including the facial 
length, and nasal and orbital breadths. The Dakotid A Ancestral Group 
was the next most closely related grouping, with the similarity greatest 
in the nasal region as expressed by the nasal height, nasal root height 
index, and the nasal index. There was some similarity in the facial breadth 
and the flatness of the face. The Dakotid B Ancestral Group was the least 
similar to the Arikara. No particular region of the cranium was related 
as a unit to the Arikara. The greatest similarity between the Arikara and 
the Dakotid B Ancestral Group was in the high nasal bones, and in a 
moderate amount of the flattening of the cranial base; the cranial vaults 
were quite different. This general picture was in agreement with that 
proposed by the original hypothesis. The relationships between the 



74 Indiana Academy of Science 

ancestral groupings and the Arikara may be summarized by the use of 
a generalized multivariate D 2 value, considering all variables^ which indi- 
cates general biological distance between populations. To place these values 
in perspective, if the statistic were applied between the Arikara and a 
remotely related American prehistoric population such as the Indian Knoll 
Archaic series from Kentucky, a value of D 2 = 24.00 would obtain. The 
close relationship between the Arikara and the Muskogid Ancestral Group 
was reflected in a D 2 value of 4.65. The Dakotid A Ancestral Group was 
not far behind, with a D 2 value of 4.90, and appeared to have contributed 
significantly to the historic Arikara. The Dakotid B Ancestral Group was 
the least related of all the putative ancestral populations tested, but the 
dissimilarity was not great; D 2 = 5.13. In this regard, the Dakotid B 
Ancestral Group appeared to be close enough to retain it as a viable puta- 
tive ancestor, a question which was left open in the initial formulation 
of the hypothesis. 

The available evidence, as summarized here, appears to lend consider- 
able credibility to the hypothesis of a hybrid origin of the Arikara. Certain 
sets of characters which serve to identify the samples employed have been 
identified, and may serve as a guide to workers planning further cranio- 

metrie studies on similar material

Abstract 

The 1971 Indiana State University Field School excavated, for the second season, 
the Daugherty-Monroe site (12-Su-13) in northern Sullivan County, Indiana. The site 
contains both Allison and LaMotte cultures. Results of tests made in two mounds were 
largely negative. Excavations in the more southern village area turned out to be pure 
Allison. Distinctive traits typical of the Allison culture included house patterns, 
storage/refuse pits and projectile points — a variant of the Lowe Flared Base type. 
Bone artifacts and refuse were rare compared to LaMotte deposits to the north, but 
this can probably be attributed to an acid soil in the area excavated. 

Introduction 

The purpose of the excavations at the Daughtery-Monroe site was 
to gather additional information on the LaMotte and Allison cultures (1). 
Excavations were carried out by the Archeological Field School directed 
by the late Dr. Edward V. McMichael. 

The site is located some 30 miles south of Terre Haute, Indiana, on 
the second terrace of the Wabash River in Sullivan County, east of Hutson- 
ville, Illinois. Before the 1970 summer excavations, it was believed that 
the site had been occupied only by people of the LaMotte culture (2). It 
was not until the last few days of the field school that an Allison component 
was discovered (1). Initial attention was diverted to a group of mounds 
in a wooded area near the LaMotte-Allison village. Approximately 13 
mounds exist in the wooded area 50 yards to the northeast of the main 
site. Mounds C and H were selected to be tested. 

A trench was opened across the center of Mound C (Fig. 1). It was 
found that a primary clay mound, approximately 15 feet diameter and 
26 inches deep, had been built, then a later secondary sand mound added. 
The clay, according to personal communications with Mr. Cantin of the 
Indiana State University Georgraphy and Geology Department, was from 
a fluvial deposit. A skelton of a horse, buried about 50 years ago, was 
found in the center of Mound C. Three Allison potsherds, numerous fire- 
cracked rocks and flint chips were found in the burial fill. No other 
features were found in Mound C. 

Mound H rose some 27 inches over its base and proved to be a single 
structure, with loading of sandy soil. Artifacts recovered consisted of a 
number of Allison Cordmarked sherds and one Baumer Fabric-marked 
rim. These were apparently carried in with the fill. There were no post 
molds or other features to indicate the function of the structure. While

no conclusion can be drawn as to their use. 



The Village 

Excavation of the southern edge of the village demonstrated that only 
Allison occupation was there. Four 10 x 10 foot units were opened, some 
300 feet south of the 1970 excavations. Altogether, 10 basin-shaped pits, 
averaging about 30 inches deep and 36 inches in diameter were found. All 
the pits, except Features 5 and 13, had a single row of post molds around 
them. The postmolds averaged about 6 inches apart and 3 inches in 



78 Indiana Academy of Science 

diameter. These posts may have supported a superstructure used as protec- 
tion. All of these were storage and/or refuse pits. 

One large refuse pit deserves special attention. This pit, Feature 13, 
was found in a 10 x 10 foot test unit, 200 feet south of the other 1971 
excavations, while searching for the village perimeter. The pit contained 
numerous Allison sherds. Apparently this was a refuse dump located on 
the edge of the village away from the main house areas. 

Portions of possibly six house patterns were also found in the village. 
Each pattern consisted of a double row of post molds approximately 12 
inches apart and with posts measuring 3 to 4 inches in diameter. At the 
present time it is unknown whether or not the pits were used in or outside 
these house structures (Fig. 1). 

Artifacts Analysis 

Artifacts from Mound C consists of three Allison Cordmarked sherds. 

The artifacts from Mound H consist of the following sherds: 195 Alli- 
son Cordmarked; 6 Embarras Simple Stamped; 1 Baumer type sherd with 
interior and exterior fabric marks and a squared rim ; and 1 piece of deer 
leg bone. This material all seems to be Allison (except for the Baumer 
rim sherd) (Table 1),

present, including: 3 cordmarked zoned, 5 simple and check stamped zoned, 
1 sherd with interior and exterior cordmarking with the interior marking 
perpendicular to the exterior, and 6 temperless "toy Pot" sherds. 

A study of the rim sherds has shown that 80.7% of the cordmarking 
is vertical to the rim (Table 2). The cordage ranges from loosely to 
tightly twisted, and from close spiced to slightly over 5 mm apart. Coil 
fractures were found on many sherds. Firing was uneven, resulting in 
both oxidation and reduction on the same vessels. The tempering of the 
sherds is fine to medium sand and grit.

Conclusions 

Although the authors regard the LaMotte culture as a direct 
descendent of the Allison culture, some variations were noted during the 
1971 field work. 

No house post mold patterns have been observed in the LaMotte 
section of the village, even though a great number of random post molds 
were found. The only house pattern found associated with Allison was a 
"D-shaped" pit house. From work on the Illinois side of the Wabash, Denzil 
Stephens suspects large circular house patterns for LaMotte. There were 
no post molds associated with the LaMotte pits, unlike what proved to be 
characteristic of Allison. 

LaMotte pits were generally much deeper, more straight-walled and 
oval to circular, although their diameters were about the same as Allison. 
Allison pits were semi-conical, while the LaMotte pits were usually basin- 
shaped. The deeper LaMotte pits may suggest an increase in population 
and consequently an increase in storage problems. 

A diagnostic trait of the Allison culture is Stoner Cordmarked pottery 
and for LaMotte, Embarras Simple Stamped pottery. A large quantity 
of bone tools were found this summer in the Allison excavation. A 
difference has also been noted between the Allison and LaMotte point 
types. Both used Lowe flared base point made of Harrison County flint, 
but LaMotte points appear to have been reworked.

A Provisional Taxonomy of Prufer's Scioto Tradition 

B. K. Swartz, Jr. 
Department of Anthropology 
Ball State University, Muncie, Indiana 47306 

Abstract 

Indiana and Ohio archaeologists have been reluctant to classify and culturally 
affiliate archaeological remains. A sympton of this unwillingness to classify is the 
forced definition of large, vague and invalidly-defined units such as Hopewell, Adena 
and Fort Ancient. The purpose of this paper is to abolish these terms as culture taxons 
by proposing a classification of Scioto Tradition phases. 

For various reasons of historic, scholastic, and idiosyncratic nature, 
Indiana and Ohio archaeologists have been loathe to define cultural affilia- 
tions from archaeological remains, that is, do archaeological taxonomy. 
It should be noted that McKern's (9) Midwestern Taxonomic System was 
developed on the basis of materials in the northern Mississippi Valley area, 
and was only nominally applied in Indiana and Ohio. Western Indiana is 
outside the range of problems discussed in this article, but terms used there 
are mostly borrowed from Illinois archaeology. Prufer's recent work in 
Ohio, however, has radically altered established views of conventional 
classification schemes there. 

A symptom of this unwillingness to label is the forced definition of 
large, vague, and invalidly defined units. Such terms as Hopewell, Adena, 
and Fort Ancient hang on to plague contemporary comparative archaeo- 
logical study. The purpose of this article is to rectify past sins, and, at least, 
to abolish two of these terms as taxa {Hopewell might be maintained in 
a ceremonial complex status, with its "Interaction Sphere," and/or a 
pottery type designator — but not as a cultural unit). For an up-to-date 
treatment of Fort Ancient see Prufer and Shane (15). Part of the 
reluctance to classify Midwestern Woodland materials is that so little data 
are available from living areas. Ceremonial remains do not seem to be sensi- 
tive spatial indicators, probably due to the rapid diffusion of associated 
religious concepts, as materials related to subsistence technologies. 

Using the classification precepts of Willey (19) Prufer has proposed 
a "Scioto Tradition" (12). This concept is based on the belief that there 
is a continuity of development in the Ohio Valley of basic Woodland 
character which is largely unknown due to absence of detectable living 
sites. This assumption is not accepted by all workers in the field. The term 
Scioto is unfortunate in that it includes southeastern Indiana, southern 
and central Ohio, north central and eastern Kentucky, and western West 
Virginia besides the focal Scioto River drainage of south central Ohio 
(16, p. 212 and Fig. 3, p. 218; 17, p. 137). A specific site name or, per- 
haps, an appropriate descriptive geographical term should have been chosen. 
The term Scioto Hopewell, rather than Ohio Hopewell, does have some geo- 
graphic plausibility though, in that the Scioto basin is the climax area, 
and manifestations of this development, though largely restricted to Ohio, 
do occur in some adjoining states.

It is very dangerous to place time limits on archaeological units, but 
the beginnings of the Scioto Tradition appear around 2000 B.C. The tradi- 
tion is completely prehistoric, being displaced by Late Woodland and 
Mississippian populations, such as those of the Fort Ancient Tradition. 

Along with Scioto, there are a number of Woodland traditions in the 
eastern United States which in some stage of development manifest a 
strong cast of Hopewell ceremonialism (5, Fig. 3, p. 181). It is believed 
that Hopewell ceremonialism evolved within the Havana Tradition of 
Illinois. 

Although Prufer has described "Scioto Hopewell" in various publica- 
tions, a set of traits defining the Scioto Tradition as a whole has yet to 
be put forth. In fact the literature suggests that Scioto Hopewell is 
confused with Scioto Tradition. Struever's map (16), for example, should 
read Scioto Hopewell for Scioto Tradition, and his definition of Scioto 
Tradition refers to Scioto Hopewell. It must be realized that Prufer's 
approach to this material has been from his initial interest in "Classic 
Hopewell" (11). The integrating feature of the tradition as perceived by 
Prufer appears to be cordmarked utilitarian pottery. Scioto can be con- 
trasted to the Havana Tradition by the presence of extensive ceremonial 
cremation and a deciduous forest setting. 

Table 1 represents a taxonomy of the Scioto Tradition, with units 
comparable to what Prufer calls phases, following procedures character- 
istically applied to the Southwest United States. These are essentially 
"generations of pottery makers" (6, p. 98), in river valleys. Local variants 
of what Prufer (13, p. 49), calls Early Middle, Late, and Latest 
[Scioto] "Hopewell" are, therefore, assumed to be components, though 
generic terms are not given. The table is not complete as regional phase 
sequences can probably also be established for the Miami and Muskingum 
drainages in Ohio. Selective explanation of phase terms proposed seems 
required. The most striking feature is the complete absence of the term 
Adena. Early Adena is replaced by Fayette, from Fayette Thick pottery 
(4). Robbins, from Dragoo's Robbins Complex (3, p. 269), has become the 
term for Middle and Late Adena. Fayette is too generalized to divide into 
phase units at this time. It differs from Munson's (7) Marion Culture of 
the Havana Tradition in that pottery is typically decorated by cordmark- 
ing, rather than by fabric impressing. Fayette and Marion pottery is quite 
thick. Michael J. Rodeffer (personal communication, 1972) is of the opinion 
that, on the basis of burial evidence, the dichotomy between Fayette and 
Robbins is not apparent in the Licking basin, and proposes a general Early 
Scioto Hartman Phase. The writer believes, though, that ceramic evidence 
will eventually indicate a division of this unit. Westenhaver, following 
Black's thinking (2, p. 301), is called Adena by Prufer (14, p. 130), and 
Charleston is called Adena by McMichael (10, p. 37-8). This writer is term- 
ing Prufer's Hopewell Phase McGraw (after Prufer's McGraw site) (14). 
New Castle, rather than Mounds or Anderson, is used for Indiana Middle 
Scioto because of the recorded presence of Hopewell pottery (18). Prufer's 
term Peters (14) seems preferable to Baby's Cole (1), since it is defined 
on the basis of pottery. An intrusive infant burial (8) was extracted from 
Earthwork Four, West Mound, at the New Castle site, indicating possible

evidence of Late Scioto occupation in east central Indiana. The term "Little 
Blue," from the nearby Little Blue River, is tentatively coined here to 
represent this manifestation and the phase it represents. Excluding the 
term Charleston, McMichael (10) is followed for Kanawha valley phases. 
McMichael's phrase Kanawha "Tradition" should be replaced with 
Kanawha Regional Sequence.

Multivariate Analysis and Human Skeletal Populations

Abstract 

The problems of determining the relationships of archeologically-derived human 
skeletal populations are discussed. Multivariate analysis is examined in terms of its 
statistical basis, its value as a tool in studies of human skeletal populations, and its 
development and history of application in anthropology. The specific technique of 
multiple-discriminant analysis and its application to problems of microevolutionary 
change is discusssed. 

One problem in studies of populations based on archeological sites 
is delimiting the population's boundaries. This may be done on the basis 
of grouping skeletal materials according to association with particular 
assemblages of artifactual materials. If different populations resemble 
one another in a number of diagnostic characteristics, they may be com- 
bined into larger groupings. Temporal boundaries are established with 
the aid of analysis of differences found in cultural materials at different 
stratigraphic levels, and from the dating of specific periods in the overall 
complex. Both temporal and spatial delimitation provide the framework 
for the establishment of relationships of the population. The remains of 
a specific culture are assumed to constitute an intrabreeding population 
which may be characterized by a cluster of characteristics and form a 
recognizeable stabilized entity, whose pattern of variation is known. Only 
after analyzing the physical characteristics of the available remains and 
comparing the results with other delimitable populations can particular 
samples be identified as having a certain likelihood of relationship with 
a particular archeological population or well-defined tribal grouping. Since 
one purpose of many studies is the selection, identification, and evaluation 
of traits having diagnostic phyletic significance for the samples involved, 
attention must be given to the selection of traits that have historic mean- 
ing at a particular level of differentiation. The premise is that these traits, 
and functional combinations of them, will best reflect the genetic con- 
tinuity of the populations in accord with other evidence. Once traits have 
been identified, the populations may be compared to a number of other 
series. It should be emphasized that combinations of traits rather than 
individual traits, whether continuous or discontinuous in nature, serve 
to delimit and identify a group. 

Of the characteristics which can be studied in prehistoric bone 
material, little is known of the specific genetic factors involved. Despite 
this limitation, in almost every case nothing else remains of the biology 
of early man, and as much reliable and useful information as possible must 
be obtained. It is apparent from the nature of the patterns of distribution 
of the values of the measurements and observations that these traits are 
polygenic in nature. Although the genetic and environmental components 

86 



Anthropology 87 

are not presently quantifiable, this variation is in no way detrimental 
to the use of these traits for comparative purposes; it is rather the nature 
of varietal groupings to exhibit a degree of overlapping in their character- 
istics, and the statistical methods employed in descriptive and inductive 
presentations in general make use of, assess, and in fact require this varia- 
tion for their proper application. Indicial traits, demonstrating an absolute 
relationship of proportion between two measurements, may be employed 
along with measurements and observations. Change on a varietal level 
may occur in the form of an overall reduction or increase in gross size, 
with the form of the cranial proportions remaining constant. This has 
been demonstrated for Amerind varietal groups (1), and may reveal 
relationships that are not obvious from measurements alone. 

In an analysis that deals with relationships and similarities of human 
skeletal populations it is appropriate to use a tool such as multivariate 
analysis, which considers the total physical variation present, and assesses 
the relative contributions of each variable in distinguishing between 
groups. A condition which must be met for such an analysis is that the 
same kinds of data be collected for all individuals of all groups under 
consideration. Assumptions which must be made are that the various 
samples have a multivariate-normal distribution, a common dispersion 
matrix, and a linear correlation between variables. A multivariate analysis 
is characterized by its consideration of a number of characteristics simul- 
taneously in assessing the relationships or discriminating traits between 
two-or-more groups or sample series. The important distinction of this 
statistical approach is that the totality of biological variables are con- 
sidered in combination, as systems. The interrelationship of all the 
morphological characteristics of the individual and the relative signifi- 
cance of each variable is considered. The significance for evolutionary 
change of individual traits can only be assessed in terms of their relation- 
ships to other traits. All biological characteristics interact. A bone or a 
tooth or a skull is a unit, and should be dealt with as such rather than 
as an assembly of individual traits. Bronowski and Long (4) said that 
the correct statistical method for the study of discrimination in anthro- 
pology must treat the set of variables as a single coherent matrix, a 
capsule summary of the multiple-discriminant technique. The individual 
is preserved as a vector of all his characteristics, taken together with all 
they convey as to size and shape by both absolute magnitude and by 
covariation. The relative contribution of each variable in discriminating 
between groups is assessed, and "weights" are assigned accordingly. 
Therefore, only what is really significant in the particular comparison 
is utilized, and exactly which variables are important and in what magni- 
tude is brought out by the technique. The technique deals with the possi- 
bility of a particular variable, which in itself is not a good discriminator 
between groups, emerging as highly valuable when taken in combination 
with other variables. 

The amount of calculation involved in this type of analysis has severely 
limited its use of anthropology until recently; a computer is a necessity. 
Pearson's "coefficient of racial likeness" or C 2 was one of the earliest 
statistics to utilize multiple measurements, and was a test of the statistical 



88 Indiana Academy of Science 

significance of difference between populations rather than a true measure 
of biological distance. This statistic was later revised to be a measure of 
biological distance, and to handle intercorrelations. Mahalanobis (9) 
developed a still useful statistic referred to as D 2 , or the generalized 
distance statistic. The D 2 procedure measures the extent and direction 
of morphological separation between groups, and makes possible an 
analysis of relationships between continuous variables, discounting the 
correlation existing between them. Fisher (7) considered D 2 as the best 
available statistic for estimating biological similarities and differences 
between groups. In 1936, the concept of discriminant function analysis 
was introduced by Fisher, a new method of testing significance for 
multiple measurements. A procedure was devised for estimating test 
weights in such a way that a linear combination of the weighted scores 
(called discriminant function coefficients) would provide a maximum 
discrimination between groups of individuals. The compounded measure- 
ments maximize the variation between groups, relative to the variation 
within groups. The use of multiple-discriminant analysis in anthropo- 
logical research is only now becoming common, and is not as yet 
widespread. With the increasing availability of computer facilities the 
calculation necessary for its application will become less of a problem. 
A number of investigators have employed it in research of an anthropo- 
logical nature (3,8,10). Fortran computer programs for multiple- 
discriminant analysis are available (5,6). Dixon's BMD 04M program 
computes means of the variables for each group and the mean difference, 
variance-covariance matrix, inverse of the variance-covariance matrix, 
discriminant function coefficients, Mahalanobis' D 2 and associated F sta- 
tistics, and the discriminant scores for the groups with their means, vari- 
ances, and standard deviations. Scaled vector values to show the relative 
contributions of the variables to each function may be obtained from 
the Fortran V program Multivariate Discriminant Analysis (2). Scaled 
vector values are discriminant function coefficients computed after 
standardization of variables, and give an accurate picture of the relative 
contributions of the particular measurements or indices contributing to 
discrimination. In applications of the method to hybridization or classifica- 
tory studies, a high scaled vector value indicates a major contribution 
to group separation, or a low relative similarity between groups for the 
particular variable. A low scaled vector value indicates that the variable 
does not contribute greatly to group separation, and is a biological feature 
which has not changed between, for example, a hypothetical ancestral 
population and a hybridized descendant group. A "morphological score" 
is computed for each individual hybrid skull on the basis of the discrimi- 
nant function coefficients obtained from the comparison with potential 
ancestral or contributor series. The biological position of each individual 
is assessed, in addition to the relationships between the series considered 
as units. The relative contributions of each series, with respect to each 
variable used, is obtained. In classificatory studies, the position of each 
individual may be assessed and the specific factors accounting for this 
position identified. An initial set of variables may be reduced to a smaller 
number of variables for further studies, and the overall direction of 
morphological trends in the samples obtained. 



Anthropology 89 

Since in a multivariate analysis it is possible to treat a skull as a unit, 
rather than as a series of single traits, and to compare these traits in 
population terms, inter-related measurements likely to bring out aspects 
of size and shape characterizing populations should perhaps be the goal 
in mind. Characteristics which would be useful in characterizing popula- 
tions may be identified which are not at all those which have been 
traditionally used in univariate skeletal comparisons. In this regard, 
there is much need for continued experimentation.

Inorganic Arsenate as a Tool for Genetic and Biochemical Analysis of 
Photosynthetic Metabolism in Algae. Robert K. Togasaki and 
Margaret 0. Hudock, Department of Botany, Indiana University, Bloom- 

ington 47401.- Wild type cells of C hlamydomonas reinhardi were grown 

on acetate supplemented agar plates, containing varied concentrations 
of inorganic arsenate, and the number of surviving colonies were scored. 
The concentration of arsenate required to inhibit growth was lower in 
the light than in the dark. Addition of 3-(3,4-dichlorophenyl) 1-1,1- 
dimethylurea, or DCMU, to the solid medium decreased the cell's sensi- 
tivity towards arsenate in the light, but did not affect sensitivity in the 
dark. Several mutant strains, each carrying a specific defect in its photo- 
synthetic apparatus, were tested for their response towards arsenate, 
and all were found to be more resistant in the light than wild type cells. 
The potential application of this system to genetic analysis of 
photosynthesis, and also some possible explanations for the observed 
phenomena was discussed. 

The "Liquid" Endosperm of Grasses. Paul Weatherwax, Department 
of Botany, Indiana University, Bloomington 47401.— A few species 
of Gramineae have an endosperm which remains soft and plastic even 
after the seeds have been stored dry for many years. The cell walls are 
thin and fragile, and the stored food consists of what seems to be a fatty 
matrix surrounding the nucleus and numerous minute starch grains. This 
type of endosperm is distributed in such an erratic way in the grass family 
that thus far it seems to have very little taxonomic significance. 

The Dichotomous Dilemma. Arthur T. Guard, Department of Biological 
Sciences, Purdue University, Lafayette, Indiana 47907.— — -Very early in 
the history of plant morphology, the growing apex of multicellular plants 
became recognized as a focal point of interest. The final form of the plant 
is very largely determined by the development of this apex and the 
appendages which it produces. The biochemical compounds which so 
profoundly affect the plant's development often originate in this area. 

In view of these facts, it is indeed surprising that one finds such 
confusing and conflicting usage of the term, "dichotomous branching", 
in the descriptions of apical growth and development. This paper presented 
some of the observable forms of apical branching and how the term has 
been used in reference to these forms. 

A Comparison of Modern and Cretaceous Sassafras Leaves. Ronald A. 
Riepe and David L. Dilcher, Department of Botany, Indiana Uni- 
versity, Bloomington 47401. A study was undertaken to reevaluate 

the fossil record of Sassafras using a comparison of leaf form and fine

venation of modern and fossil material. Sassafras, a monotypic genus 
which has been identified early in the fossil record of angiosperms, has 
leaves that are entire, asymmetrically bilobed, or trilobed, but may possess 
up to six lobes (Berry, 1902). The form of the lobes and sinuses may be 
extremely variable. Berry stated that the venation of the basal portion 
of the blade was a constant character which could be used to differentiate 
Sassafras from Aralia, Cissites, and Platanus. The distinctive marginal 
vein pattern of Sassafras may also be used in classification, however this 
character could be obliterated easily or overlooked in fossil forms. Ward 
(1887) pointed out the remarkable character of the marginal veins of 
the sinuses in modern leaves. Lesquereaux (1892) wrote of many of his 
identifications of leaf remains from the Dakota Group with some uncer- 
tainty. By 1902, twenty-eight American forms of Sassafras had been 
published. Berry retained only six forms in the genus Sassafras, referring 
others to Aralia, Cissites and Platanus. The leaf form and venation 
characters of Sassafras have been reevaluated and applied to the fossil 
record. 

Structure of Glandular Hairs of Marihuana. Charles T. Hammond and 
Paul G. Mahlberg, Department of Botany, Indiana University, Bloom- 

ington 47401. Glandular hairs on the bracts of pistillate flowers of 

marihuana (Cannabis sativa L.) were viewed with the aid of light, 
electron tramission, and electron scanning microscopy. Three morpho- 
logically distinct types of glandular hairs occur on bracts: bulbous, 
capitate-stalked, and capitate-sessile. Bulbous glandular hairs, which are 
small and composed of only a few cells, consist of a globular head of one 
to several cells positioned on a basal cell or cells. Capitate glandular hairs, 
whether stalked or sessile, have a flattened multicellular cap composed 
of 8 to 13 cells which are covered by an abundant secretory product. The 
secretory product accumulates beneath a membranous sheath which is 
derived from the outer surface of the cap cells. Maturing cap cells have 
a large central vacuole with a very dense peripheral cytoplasm. The cyto- 
plasm contains dictyosomes, endoplasmic reticulum, and plastids with 
crystaline inclusions. Large pores in the walls between neighboring cells 
contribute to the formation of a continuous protoplast in the cap. The 
possible association of capitate glandular hairs with production and/or 
localization of the hallucinogen tetrahydrocannabinol (THC) was discussed. 

Chromic Acid as a Selective Stain for Laticifers in Vinca rosea. LARRY 
R. Yoder and Paul G. Mahlberg, Department of Botany, Indiana Uni- 
versity, Bloomington 47401. A mixture of equal parts of 10% chromic 

acid and 10% nitric acid added to living tissues of Vinca rosea causes some 
cells to turn bright red within a few minutes. Acidified chromate and 
dichromate salts produce the same effect indicating the dichromate anion 
as the reactant. Reacting cells included occasional parenchyma cells in 
the pith, stem cortex and root cortex along with laticifers in all parts 
of the plant. Use of this staining procedure permitted delineation of 
Vinca's entire non-articulated, unbranched laticifer system with a mini- 
mum of preparation. Some coloration appears if latex exudes directly into 
the reagent, but no reaction occurs if latex stands 30 to 60 seconds. 
Staining only occurs when living cells are treated and the coloration fades 
after 10 to 15 minutes and cannot be restored. Tissues which have been 



Botany 93 

frozen, fried, heated above 55 degrees Centrigrade, or treated with an fix- 
ative are unreactive. The same cells vitally stain with neutral red and 
toluidine blue indicating a low pH and possible lysosomal activity. Al- 
though the reaction is not common to all latex-bearing plants, coloration 
does appear in laticifers of Vinco minor, Plumeria, Asclepias and some 
euphorbias. The reaction is postulated to be dependent upon a lower pH 
in these specialized cells, and any treatment which interferes with main- 
tenance of this acid condition also blocks the reaction with chromic acid. 
The precise nature of this reaction is yet to be determined. 

The Terminal Inflorescence of the Maize Mutant Tassel seed-2. C. L. 

Gehring, Department of Life Sciences, Indiana State University, Terre 
Haute, Indiana 47809, and S. N. Postlethwait, Department of Biological 
Sciences, Purdue University, Lafayette, Indiana 47907. — —A morpho- 
logical and histological examination of developmental changes in the 
terminal inflorescence of the maize mutant, Tassel seed-2 was conducted. 
Plants were grown in environmental control chambers under the 
conditions: 80 degrees Fahrenheit during 16 hours of artificial light 
(flourescent and incandescent) and 65 degrees during an 8-hour dark 
period. 

Two plants a day were removed from the growth chamber starting 
19 days after planting and terminating 67 days after planting. Examina- 
tion of these plants revealed that the sequence of development and 
arrangement of floral structures are similar to comparable structures 
in normal maize. Primordia for both pistillate and staminate flowers are 
initiated in all flowers. However, in tassels which develop functional 
pistaillate flowers, the staminate primordia abort. Pistillate primordia 
abort in the tassels which develop functional staminate flowers. 

One hundred and nine days after planting, 28 plants were harvested; 
16 plants had 100% pistillate tassels and they averaged 560.6 silks per 
tassel and 12 plants had completely staminate tassels which averaged 
281.3 stamens per tassel. 

A Review of the Fossil Apocynaceae from the Eocene of Western Ten- 
nessee and Kentucky. Gary E. Dolph, Department of Botany, Bloom- 

ington 47401. Fossil leaves similar to those described by Berry in 

the form genus Apocynophyllwn were collected from the Claiborne Forma- 
tion (Middle Eocene) of western Tennessee and Kentucky. Fossil material 
representing three of Berry's original eleven species of Apocynophyllum 
— A mississippiense, A. crassum, and A. wilcoxense — was found. Fossil 
leaves of A. mississippiense, a species characterized megascopically by 
closely spaced major lateral veins and a broadly alate petiole, were divided 
into two groups based on the presence or absence of cuticular flanges on 
the abaxial cuticle. In addition, two previously undescribed leaf types 
which also possessed alate petioles were distinguished from A. mississip- 
piense. The first showed a much greater spacing between the major lateral 
veins than A. mississippiense but yielded no cuticle. The second, whose 
gross morphological features (except for the alate petiole) were totally 
distorted, yielded a cuticle which lacked the trichome bases characteristic 
of A. mississippiense. Apocynophyllum crassum has a broad petiole that 



94 Indiana Academy of Science 

is woody throughout and not alate as in A. mississippiense. In the preced- 
ing four leaf types where cuticle has been isolated, the paracytic accessory 
cell arrangement common to some extant members of the Apocynaceae 
was found. Although a superficial resemblence exists with regard to acces- 
sory cell arrangement, differences between the morphological character- 
istics of the fossil leaf types and that of the extant members of the 
Apocynaceae precludes the assignment of the fossil material to any extant 
genus of the Apocynaceae. Fossil leaves, whose closely spaced, subparallel 
major lateral veins terminate in a distinct marginal vein, were divided 
by Berry among A. wilcoxense and select fossil species of Ficus and 
Myrcia. Upon examination, only one leaf type characterized by internal 
mucilaginous cavities was discerned. Internal mucilaginous cavities are 
not characteristic of the Apocynaceae or Moraceae but are found in the

Revaluation of Engelhardia of the Eocene of Southeastern United States. 

Frank W. Potter, Jr., and David L. Dilcher, Department of Botany, 

Indiana University, Bloomington 47401. Several species of fossil 

fruits, leaves and pollen from the Eocene of southeastern United States 
have been assigned to the genus Engelhardia. Recent examination of 
modern representatives of Old and New World sections indicates sufficient 
diversity to warrant segregating the New World members into the genus 
Oreomunnea. Two fruits of E. puryearensis Berry were obtained from 
the Puryear clay pit, Puryear, Tennessee; both specimens are impressions 
of the three anterior lobes. No fourth posterior lobe is present. The an- 
terior wings of the fossil show venation patterns similar to the New World 
group, particularly O. mexicana. Based on the fruits, E. puryearensis is 
more closely aligned to Central American populations than Asiatic taxa. 
Other Engelhardia fruits reported by Berry suggest the presence of both 
genera in the southeastern United States during the Eocene. Modern 
pollen is not sufficiently distinctive to conclusively separate New and Old 
world sections. To date, no fossil leaves have been obtained that can be 
assigned to either the genus Engelhardia or Oreomunnea, although the 
two extant genera show distinct morphological and cuticular differences. 
The presence of leaves could be important foi determining the relation- 
ship of the fruits to Engelhardia and/or Oreomunnea. 

Middle Eocene Sabaloid Palms. C. P. Daghlian and D. L. Dilcher, 

Department of Botany, Indiana University, Bloomington 47401. E. 

W. Berry reported three palm types from the middle Eocene clay deposits 
of western Kentucky and Tennessee. Two of these were pinnately com- 
pound types. The third being palmately compound. The palmate palm 
fossils in the Indiana Paleobotanical collection from the same sediments 
suggest that there are more than one genus and species of palmately 
compound palm leaf fossils. Berry's specimens of Sabalites grayanus, were 
identified primarily on the basis of gross features, leaflet distribution 
and venation. A detailed study of the palm material from the Indiana 
University collection is in progress and a thorough examination of fine 
features, particularly cuticular characteristics, as well as gross features 
has indicated that there are clearly two and perhaps three kinds of 
pramately compound palm leaf fossils rather than the one that Berry 



Botany 95 

reported. The first group has been identified as a member of the genus 
Sabal indicating that it was a clearly defined group as early as the middle 
Eocene. These palms are large, costa-palmate leaf fragments similar to 
modern sabals such as S. texana. The second group is comprised of palmate 
leaf fragments of Sabalites grayanus but contains two subgroups. Those 
show differences in venation and the pattern of their stomatal apparatus. 
These findings are important because they show a greater diversity of 
palms in the flora of these middle Eocene sediments. 

Cell Wall Regeneration Around Protoplasts Isolated from Convolvulus 
arvensis Tissue Culture. Randall K. Horine, Department of Biology, 
Earlham College, Richmond, Indiana 47374, and Albert W. Ruesink, 

Department of Botany, Indiana, University, Bloomington 47401. 

Protoplasts of Convolvulus arvensis L. tissue culture regenerated a wall- 
like structure within 3 days in culture. Although unusually electron dense 
and atypically amorphous in the electron microscope, this structure could 
be digested with cellulase but was resistant to protease, pectinase, and 
/3-1,3-glucanase just like the original wall. A cytochemical test for callose 
was negative. Wall regeneration required a readily metabolized external 
carbon source and was not inhibited by a high concentration of cyclo- 
heximide, puromycin, or actinomycin D, suggesting that stable, long-lived 
protein or messenger RNA is involved in its synthesis. Protoplast budding 
was correlated with the wall regeneration and the latter was related 
quantitatively to the sucrose concentration in the medium. Auxin (2,4- 
D) neither promoted nor inhibited wall regeneration at any concentration. 
Culturing protoplasts in the presence of proteolytic enzymes decreased 
their ability to undergo cell wall regeneration, although the concentration 
required was so high as to suggest that the proteins involved must be 
at least partially buried in the plasma membrane. 



Initiation of Callus Tissue of Abies concolor (White Fir) by 
Tissue Culture Techniques 

Richard W. Olsen and Arthur L. Eiser 
Department of Biology 
Ball State University, Muncie, Indiana 47306 

Abstract 

Callus tissue of Abies concolor (Gord. and Glend.) Lindl. was initiated from 
inocula prepared from terminal stem tissue on a modified Winton medium containing 
basis salts, organic nutrients, growth regulators and a stem extract of Abies concolor. 
Under controlled environmental conditions, the callus has grown and has been main- 
tained through subsequent subculture for ten months. 

Introduction 

Culturing of gymnosperm tissues under aseptic conditions has been 
difficult to achieve. Approximately 27 gymnosperm species have been 
successfully cultured, however (1-13). Among these 27 is grand fir (Abies 
grandis) the only representative of the genus Abies to have been success- 
fully cultured to date (6). 

We now report the initiation of callus tissue from stem tissue of 
mature Abies concolor (Gord. and Glend.) Lindl. trees. 

Materials and Methods 

The inocula used in this study were obtained from branches (which 
were less than 3 m above the ground level) of mature Abies concolor 
trees. Terminal stem sections approximately 10 cm long and consisting 
of the current year's growth were used; before taking, each stem section 
was sprayed with 70% ethyl alcohol. Cuts were made with sterile scalpels. 
After making the cut, the basal end of each stem section was sprayed with 
70% ethyl alcohol and placed in a separate, unused, plastic bag and the 
opening of the bag was fastened securely. 

In the laboratory, one stem section at a time was removed from its 
plastic bag and immersed in a shallow container of 70% ethyl alcohol. 
While immersed in the alcohol, all the needles were removed with a scalpel 
at their junction with the stem. Each de-needled stem section was trans- 
ferred to a dry, sterlized, 500 ml Ehrlenmeyer flask equipped with a screw 
cap. After the stem sections were de-needled and placed in the flask, 250 
ml of fresh, household bleach (5.25% sodium hypochlorite) were added, 
along with 2 drops of Tween 20 (polyoxyethylene sorbitan monolaurate) , 
a wetting agent used as a surfacant. The flask was agitated frequently 
during the 10-minute interval that the stem sections were sterilized. The 
bleach was decanted, and the stem sections were rinsed 3 times with 
sterile, distilled water. The sterilized portions of stems were cut into sec- 
tions approximately 8-10 mm in length. The end sections were discarded, 
while the others were inserted, basal end up, in 25 ml of an agar nutrient 
medium in 20 x 100 mm petri dishes.

Callus was successfully initiated and maintained on a modification 
of Winton's medium for triploid quaking aspen (14-17). Winton's medium 
was modified by the addition of gibberellic acid, indoleacetic acid, naphtha- 
leneacetic acid, ascorbic acid, L-glutamine, myostatin (a fungicide), and 
a stem extract of Abies coneolor. On this undefined medium (Table 1), 
cell proliferation occurred within 14 days while the plates were being 
maintained in the dark in an incubator at 27.5 ± 2° C under satur-

Electron Microscopic Study of Anaplasma marginal by Negative Staining. 
F. Padgett and W. A. Summers, Department of Microbiology, Indiana 
University School of Medicine, Indianapolis 46207. — —Studies of the 
morphologic features and reproduction of the initial bodies of Anaplasma 
marginale were done by the negative contrast (phosphotungstic acid) 
technique of unfixed, dehemoglobinized, infected bovine erythrocytes. The 
internal structure appeared to be organized as a coiled, tubular, or ribbon- 
like structure. The reproduction process, reconstructed from observation 
of static preparations, began with the formation of a "budlike" structure 
in the initial body. 

Growth Cycle of Penicillium chrysogenum Virus. L. F. Ellis and 
R. J. Douthart, Eli Lilly and Company, Indianapolis, Indiana 46206.— 
Pennicillium chrysogenum was grown in stainless steel fermenters with 
continuous agitation and aeration. During the fermentation aliquots were 
withdrawn and were centrifuged to harvest the cells. Either the virus 
particles of the double stranded RNA (dsRNA) was isolated from these 
cells. The amount of dsRNA per gram of mycelia increases until approxi- 
mately 60 hours incubation and then declines. Physical and biological 
properties suggest this dsRNA is of viral origin. Other aspects of this 
virus were discussed. 

Toxic Response of Mice to a DDT Diet, Its Supression by Feeding and 
the Effect of Estrogen. Dorothy A. Werderitsh, D. Shelton, C. 
Swan, C.-M. Haun, W. Yunghans and D. J. Morre, Department of 
Botany and Plant Pathology, Purdue University, Lafayette, Indiana 47907. 
——Mice, 4 to 5 weeks old, of the C3H/HeJ strain or from the Purdue 
University colony received ad libitum water and laboratory chow to which 
corn oil (1:10, weight/ weight) was added. For those animals receiving 
DDT, technical grade DDT (1, 1, l-trichloro-2 2-his (p-chlorophenyl) 
ethane) was added to the corn oil to give a final concentration of 900 
parts per million DDT in the total diet. Overt signs of DDT toxicity ap- 
peared as early as the 5th day after DDT feed was offered. Most of the 
animals died within 3 days after the onset of severe symptom development. 
If the animals were withdrawn from the DDT feed and presented with 
control feed in the initial stages of tremor development, they recovered 
within 8 to 12 hours and exhibited normal behavior. Yet, if animals 
previously receiving DDT feed were fasted to starvation levels several 
weeks later, symptoms of DDT toxicity reappeared. Control animals fasted 
to the same weight levels did not develop tremors or other overt signs of 
DDT toxicity. It was not possible to prevent, reverse or significantly delay

the toxic response to DDT by administration of estrogen (subcutaneous 
injection of 5 micrograms estradiol cyclopentylpropionate in 100 micro- 
liters corn oil per animal). Apparently, a significant factor in effecting 
recovery of the animals from DDT toxicity is the removal of the source 
of the DDT and offering of a normal diet to reestablish a pattern of 
weight gain and caloric balance. 

NADH Dehydrogenase Activity of Golgi Apparatus from Rat Liver. 

C. M. Huang, D. J. Morre, Department of Botany and Plant Pathology, 
and T. W. Keenan, Department of Animal Sciences, Purdue University, 

Lafayette, Indiana 47907. Highly purified rat liver Golgi apparatus 

(GA) fractions exhibited NADH dehydrogenase of specific activity 
approximately one-fourth that observed with endoplasmic reticulum (ER). 
With exogenous cytochrome c as electron acceptor, apparent Km's for 
NADH were 6.17 and 6.09 ^M for GA and ER, respectively. The activity 
in both membrane fractions was insensitive to rotenone and Pieridine 
A, potent inhibitors of mitochondrial NADH dehydrogenase. With ferri- 
cyanide as acceptor, the apparent Km for ferricyanide was 26.7 ^M for 
both ER and GA and excess of substrate inhibited activity with both 
membrane fractions. Maximal velocities for the NADH-ferricyanide reduc- 
tase were 3.44 and 1.44 ^M NADH oxidized/min/mg protein for ER and 
GA, respectively. 

The high degree of similarity of these activities comparing ER and 
GA suggest that they are catalyzed by the same enzyme present in both 
membrane fractions. The results support the hypothesis that membrane 
material derived directly from ER is utilized for formation of GA cisterna. 

Golgi Apparatus-Medicated Cytomembrane Differentiation in Rat and 
Bovine Mammary Gland. T. W. Keenan, Department of Animal Sciences, 
and C. M. Huang and D. J. Morre, Department of Botany and Plant 

Pathology, Purdue University, Lafayette, Indiana 47907. Golgi 

apparatus (GA), endoplasmic reticulum (ER) and plasma membrane 
(PM) fractions were isolated in highly purified form from both rat and 
bovine mammary glands and subjected to compositional analysis. Included 
in the analysis was the milk fat globule membrane (GM), a membrane 
which is derived directly from the secretory cell plasma membrane. With 
regard to lipid composition, GA was intermediate between ER at one 
extreme and the PM and GM at the other with regard to levels of total 
lipid phosphorus, phosphatidyl choline, sphingomyelin, cerebiosides and 
cholestrol. Fatty acid composition of GA polar lipids was intermediate 
between ER and PM. Polar lipids of ER contained higher levels of unsatur- 
ated fatty acids whereas PM and GM contained higher levels of saturated 
fatty acids. 

Levels of membrane protein-bound sialic acid were lowest in ER, 
intermediate in GA and highest in PM and GM. Salt-washed ER, GA, PM 
and GM membranes displayed several protein bands with identical electro- 
phoretic mobilities. Golgi apparatus was also intermediate between ER 
and the PM and GM with respect to specific activities of the enzymes 
NADH dehydrogenase, 5'-nucleotidase, and adenosine triphosphatase.

These results are compatible with the hypothesis of GA-mediated 
cytomembrane differentiation. Further, they confirm previous results 
obtained with rat liver cytomembranes and extend them to another cell 
type with different secretory functions, 

Ultrastructure of Green Plastids in Leaves of Genetic Albino Tobacco. 

Anne A. Susalla and Paul G. Mahlberg, Department of Botany, Indi- 
ana University, Bloomington, Indiana 47401.— Genetic green and albino 
tobacco seedlings were grown on agar with defined nutrients, growth sub- 
stances and light conditions. Albino plants developed patches of green 
on the first and succeeding leaves even though the cotyledons were always 
white. In later stages of growth, these plants became highly variegated 
with some approaching the phenotype of normal green plants. In ultra- 
structural studies, some mutant-green plastids of the albino plants have 
grana that are massive in size with many appressed thylakoids and 
irregular margins. Other plastids are large with tapered margins to give 
a spindle effect while a few have only scattered thylakoids. Osmiophilic 
globules and DNA-like fibrils are present in the stroma. Starch is evident 
but photosynthetic activity is yet to be determined. 

Use of the Scanning Electron Microscope in the Investigation of Cardiac 
and Pulmonary Tissue. Shirley Siew, Indiana University School of 

Medicine, Indianapolis 46202. -Scanning electron microscopic studies 

were performed on both fresh biopsy and autopsy specimens of cardiac 
and pulmonary tissue. The fresh material was obtained at open heart 
surgery and was fixed in Muir's paraformaldehyde electron microscopy 
fixative. After fixation, it was processed by three different methods for 
scanning electron microscopy : 

1) placed in glycerine overnight 

2) post-fixed in osmic acid and then placed in propylene glycol 

3) treated with acetone 

The specimens were then coated with gold under vacuum and were 
examined in a Cambridge Stereoscan Microscope. Chronic rheumatic aortic 
and mitral valves, papillary muscle and a biopsy of the left lingula were 
examined. The autopsy material comprised cardiac valves and lung. The 
latter was fixed under inflation. The best results were obtained in studies 
of valvular and pulmonary tissue by means of the second method. It was 
concluded that the scanning electron microscope will prove of value in 
the investigation of valvular and pulmonary disease. 

Ultrastructure of Mouse Heart Cell Culture. G. B. Boder and L. F. Ellis, 
The Lilly Research Laboratories, Eli Lilly and Company, Indianapolis, 

Indiana 46206. Newborn mouse ventricles were dispersed by short 

treatment with collagenase. Cultures derived by this method have a high 
proportion of beating cells which attach to collagen, glass or plastic within 
a few hours of isolation. Beating cells have been maintained in sterile 
culture in the absence of antibiotics for as long as 6 months and remain 
responsive to hormones. A photoelectric recording system was developed 
which is capable of measuring the rate and amplitude of contractions of 
a single myocardial cell or a colony of myocardial cells. The effects of 



104 Indiana Academy of Science 

drugs on these cells was reported in 1971 by Boder et al. (Nature 231: 
531-532). We have been studying the ultrastructure of the cultured cells. 

This report compared the cultured cells to those of the intact myo- 
cardial tissue. Myofibrial filaments were observed in the cell cultures. 

Ultrastructures of Neuronal Lipofuscin and Ceroid. Itaru Watanabe, 
Vimal Patel, and Wolfgang Zeman 1 , Department of Pathology, 

Indiana University School of Medicine, Indianapolis 46202. Lipofuscin, 

an autofluorescent yellow pigment in the residual body, is considered to 
be indigestible by lysosomal acid hydrolases. This pigment is stained 
positively by conventional fat staining technique and hence the term 
"lipid pigment". The pigment is also called "wear and tear" or "age" pig- 
ment because it is found most abundantly in the cells of aged individuals. 
Actually, in the senile brain, the material occupies a large area of the 
nerve cell body by displacing the nucleus and other cytoplasmic organelles. 
Electron microscopy revealed that the lipofuscin bodies are surrounded 
by trilaminar limiting membrane and contain fine granular osmiophilic 
material. Using histochemical techniques for electron microscopy, we 
observed acid phosphatase activity in the granular matrix but not in the 
lipid portion. Our findings agree with observations by others. Recently, 
we also demonstrated some evidence of peroxidation in the lipid portion 
of this organelle, supporting the view that lipopigment is derived by 
peroxidation of fatty acids and proteins. 

Another pigment called "ceroid" is found to accumulate in brain cells 
of patients with Neuronal ceroid lipofuscinosis. Ultrastructural aspects 
of these two types of pigments, lipofuscin and ceroid, in the human brain 
were presented.

Effect of Beta-alanine on Glucose Catabolism and Growth of 
Ehrlich Ascites Tumor Cells. M. E. Jacobs, Department of Biology, 

Goshen College, Goshen, Indiana 46526. Intraperitoneal injection 

of 0.1 ml 5 M beta-alanine at the time of infection, and daily thereafter, 
inhibits tumor-weight gain of Carworth female CF1 mice by 19% by the 
end of 14 days, as compared with infected mice injected with 0.1 ml 2.5 
M NaCl. Incubation of the tumor cells at 37.5 °C in 25 mM 
beta-alanine in Krebs-Ringers bicarbonate solution at pH 7.4 inhibits 
14 C0 2 excretion from the cells using l- 14 C-D-glucose as substrate. 
The inhibition is 18-25%, as compared with control samples containing 
no beta-alanine, or 25 mM of beta-aminoisobutyric or gamma- 
aminobutyric acids. 

NOTE 

Inhibition of Succinate Oxidation in Beef Heart Mitochondria by 
Derivatives of Pyridine Adenine Dinucleotide. P. V. Blair and L. Y. 

Chao, Indiana University Medical Center, Indianapolis, 46202. 

Succinate oxidation is inhibited by nicotinamide adenine dinucleotide 
(NAD + ) in damaged or sonicated mitochondria. Two mechanisms to 
account for this NAD+-inhibition have been suggested. In 1948, Pardee 
and Potter (1) postulated that inhibition occurred because NAD-f 



Cell Biology 105 

stimulated the production of oxaloacetate an inhibitor of succinate 
oxidase, from succinate via fumarate and L-malate. In 1963 an 
alternative hypothesis was proposed by Neubert et ah (2) in which 
binding of NAD+ or one of its analogues to a site on succinate 
dehydrogenase would cause direct inhibition of succinate oxidation. 
Experiments to determine the most likely explanation for NAD+- 
inhibition of succinate oxidation were carried out on preparations of 
beef heart mitochondria. 

All dinucleotide tested, NAD+, 3-acetylpyridine adenine dinu- 
cleotide (3-AcPAD + ), 3-acetylpyridine deaminoadenine dinucleotide 
(3-AcPDeAD+), nicotinamide adenine dinucleotide phosphate (NADP+), 
NADH and NADPH with the exception of NADPH inhibited succinate 
oxidation. The inhibition had a lag period and increased with time in 
the presence of all inhibitory dinucleotides except NADP+. The 
increase in inhibition with time by NADP+ comes to an early steady 
(per cent inhibition does not change), probably because it is not 
a good coenzyme for malate dehydrogenase and because the reduced 
form (NADPH) can not be oxidized by the electron transfer chain. 
L-malate, which stimulates the production of oxaloacetate in the 
presence of NAD+ and its analogues, enhanced inhibition and com- 
pounds (glutamate, rotenone, NADH plus rotenone, and meso-tartrate) 
which remove oxaloacetate or stop its formation prevent or reverse 
NAD -{--inhibition of succinate oxidation. The oxidized dinucleotides 
do not inhibit succinate oxidation in purified electron transfer 
particles. A supernatant fraction containing fumarase and malate 
dehydrogenase restores the inhibitory ability of NAD+ to these 
purified electron transfer particles. The addition of oxaloacetate 
to these purified particles inhibits succinate oxidation with apparent 
competitive kinetics. 

Differential spectra and oxidation-reduction of the dinucleo- 
tides at absorption maxima were recorded in the presence of suc- 
cinate and L-malate. The appearance of the reduced form of the 
NAD + -analogues was positively correlated with the per cent inhibition 
of succinate oxidation. The reduced analogues accumulated from 
malate dehydrogenation because they are not rapidly oxidized by 
the respiratory chain, whereas NADH does not accumulate because it 
is rapidly reoxidized by electron transfer. Our results are con- 
sistent with the postulate that oxaloacetate is the inhibitor of 
succinate oxidation and NAD+ only stimulates the accumulation of 
oxaloacetate. None of our evilence would indicate that NAD + 
directly inhibits succinate dehydrogenation or the succinate de- 
hydrogenase enzyme.

Scale Calcification In A Chrysophycean Alga: A Test System For 
The Effects of DDT On Biological Calcification!

Abstract 

The chrysophycean alga, Coccolithus huxleyi, responds to the chlorinated hydrocarbon, 
DDT, by reduced calcification of surface scales. Cytological and biochemical findings 
show reduced calcium carbonate deposition on the scales and reduced calcium utilization 
by the organism. 

Chlorinated hydrocarbons [particularly certain types of pesticides 
such as dieldrin, DDT, DDE (a stable metabolite of DDT) and the poly- 
chlorinated biphenyls (PCB's) used as plasticizers] 3 at high levels in 
the diet, result in changes in calcium metabolism which may lead to 
eggshell thinning and reproductive failure in predators and raptorial 
birds near the top of the food chain (2, 5-13, 15, 16, 17, 19-21, 24). The 
mechanism by which these compounds reduce calcium carbonate deposi- 
tion has not been established. One possibility is that carbonic 
anhydrase is inhibited (1, 16). This enzyme catalyzes the conversion 
of carbon dioxide to bicarbonate which then reacts with calcium to form 
calcium carbonate. Another possibility, frequently mentioned, is 
hormonal imbalance (1, 10-13, 15-17). Estrogen, for example influences 
calcium mobilization to the shell gland during eggshell formation. 
Because of the hormonal complexity of the avian calcification system, 
simpler systems were sought which might serve as models for the study 
of DDT effects on eggshell calcification. 

The marine alga, Coccolithus huxleyi, secretes cell wall scales, 
certain of which are layered with calcium carbonate (14). The scales 
are produced within cisternae of the Golgi apparatus and transported 
to the cell surface via secretory vesicles (14). Calcification occurs 
during secretion. The purpose of this study was to determine whether 
DDT influenced calcification in the algal system.

Results and Discussion 

Coccolithus huxleyi secretes cellulosic scales into the cell wall (14). 
As with other Chrysophycean algae (3, 4), these scales are formed in 
the cisternae of the Golgi apparatus and are transported to the 
plasma membrane in secretory vesicles (14, Fig. 1). The scales are of 
two types that are secreted in alternating waves. Type I scales are small 
and non-calcified (Fig. 2A). Type II scales are larger and have a min- 
eralized rim around their edges (Fig. 2B). Calcification takes place 
while the Type II scales are en route to the cell wall in the secretory 
vesicles.

A typical control cell is shown in Figure 3. The alternating waves 
of Type I and Type II scales are apparent within the cell. Where 
calcification is heavy on the Type II scales (scales normally calcified), 
the mineralized deposit is lost during specimen preparation and only 
a hole is left. Loss of the deposits from the section is a criterion for 
heavy calcification that was previously reported by Manton and 
Leedale (14). 

When cells were grown in the presence of DDT, calcification in the 
wave of Type II scales being formed was markedly reduced (Fig. 4),

Further evidence for a DDT effect on algal calcification was sought 
from determinations of carbonic anhydrase activity. Results summarized 
in Table 1 show inhibition of carbonic anhydrase from the alga by DDT, 
although the effect was much less dramatic than expected. The levels of 
DDT required to inhibit carbonic anhydrase seem high but concentrations 
of 2,500 ppm of DDT have been reported from thin-shelled eggs of fish- 
eating birds (16). In experiments with 45 Ca, calcium utilization was in- 
hibited by 10 to 15% in the DDT-grown cells.

Abstract 

Galacto- and sulfolipid content has been determined in sulfur and nitrogen- 
deficient maize leaves. Only slight variations in monogalactosyl diglyceride and 
digalactosyl diglyceride levels were detected in S-deficient plants compared to 
normal maize leaves but there was a 50% decrease of both these lipids in N-deficient 
plants. The greatest difference was found in the sulfolipid content in either S- or N- 
deficiencies — the sulfolipid was reduced by 30 to 50%. Since decreased sulfolipid 
content seemed to be associated with increased Photosystem II activity and the 
occurrence of larger chloroplast grana stacks, it is proposed that sulfolipid may play a 
role in grana stacking along with other structural chloroplast lipids. At least a 
correlation between decreased sulfolipid and galactolipid content is associated with the 
occurrence of larger chloroplast grana stacks and increased Photosystem II activity. 



Introduction 

In our studies of photosynthetic activity of chloroplasts from 
nitrogen-, potassium-, phosphorus-, sulfur-, magnesium-, and calcium- 
deficient plants we found an increased Photosystem II activity in the 
chloroplasts from S- and N-deficient plants (3). Since increased rates 
for PS II activity were observed in 2 separate assay systems (water 
-> indophenol dye and diphenylcarbazide ->■ indophenol dye) and were 
correlated with increased grana stacking in studies of the fine structure 
of mineral-deficient chloroplasts by electron microscopy (9), it became 
important to investigate the role of sulfolipids in S- and N-deficient 
chloroplasts in relation to normal maize sulfolipid content. 

Nichols and James (13) have reviewed the literature on chloroplast 
lipid composition while Haines has surveyed the chemical information 
on sulfolipids (8). Plant sulfolipids have been localized in the 
chloroplast and assayed in several species of plants (1, 2, 6, 14, 16). 
Previous studies on the composition of chloroplast lipids consider 
sulfolipid a minor constitutent (<10% present) and assign a structural 
role to it. Our discovery of reduced sulfolipid content in S- and 
N-deficient plants both of which exhibit higher than normal PS II 
activity points to the importance of sulfolipid not only as a passive 
structural element but also as something critical for proper enzymatic 
activity of chloroplast grana stacks.

Materials and Methods 

Methods for nutrient culture of various mineral-deficient maize 
plants have been described (5). The galacto- and sulfolipid content of 
S- and N-deficient plants was determined as follows: 5-g quantities of 
fresh or frozen maize leaves were homogenized in 90% acetone in a 
Waring blender and strained through a sintered glass filter. The residue 
was rewashed with several aliquots of acetone. Then the total acetone 
extract was transferred to a separatory funnel containing an equal 
amount of petroleum ether (B.P. 40-60°C). Water-soluble components 
were removed by water washes and discarded. The green epiphase con- 
taining pigments and lipids was washed several times with increasing 
concentrations of methanol-water (50:50; 75:25; 90:10). The combined 
methanol-water extracts were evaporated to dryness in a rotary 
evaporator at 30° C to yield a total lipid fraction. Evaporation was slow 
and required the addition of several portions of acetone. The final dry 
lipid mixture was suspended in diethyl ether and used for thin layer 
chromatography. Silica gel G plates were developed in water, glacial 
acetic acid, methanol and chloroform (4:10:15:75) according to Nichols 
(12) or in water, benzene, acetone (8:30:91) by Pohl, Glasl and 
Wagner's method (15). Monogalactosyl diglyceride, digalactosyl 
diglyceride and sulfolipid were identified by spraying with 0.0035% 
rhodamine G in 0.5% KOH solution and observing fluorescent bands 
under U.V. light. After scraping the desired bands the various lipids 
were eluted from the silica gel with diethyl ether and evaporated to 
dryness under vacuum from an aspirator. If plates were developed in 
mixtures containing glacial acetic acid as in (12), the lipid bands were 
located by spraying one side of the chromatogram with reduced 
methylene blue spray according to Barr and Crane (4). 

Monogalactosyl diglyceride, digalactosyl diglyceride and sulfolipid 
were assayed quantitatively by the phenol-sulfuric acid method as 
described by Roughan and Batt (16). Sulfolipid was also determined 
as inorganic sulfate after charring and acid hydrolysis in sealed glass 
tubes. The spectrophotometric analysis of sulfate with barium 
chloranilate reagent was performed according to Dittmer and 
Wells (7). 

Results 

The visible symptoms of sulfur- and notrogen-deficient maize leaves 
compared to normal maize are shown in Figure 1 (A). This figure 
also shows a thin layer chromatrogram (B) where the sulfolipid spot 
is visible as a light charred area in the control but not at all in 
S-deficient plants in which the sulfolipid content is reduced by about 
half. Figure 1 (C) shows the results of the phenol-sulfuric acid test 
for sugars by which monogalactosyl diglyceride and digalactosyl 
diglyceride can be identified by their galactose moiety and sulfolipid 
by its quinovose moiety. By using spectrophotometric comparisons to 
galactose standards, the sulfolipid content of normal maize leaves is 
higher than that of S-deficient leaves.

Table 1 summarizes the results of chloroplast lipid analysis. In 
S- and N-deficient leaves the sulfolipid content is reported from either 
of 2 separate assays: 1) by analysis of the sugar moiety using the 
phenol-sulfuric acid test and 2) by sulfur analysis with the barium 
chloranilate test for inorganic sulfur. The results of both tests 
indicate a reduced sulfolipid content of S- and N-deficient leaves in 
contrast to normal maize while differences in galactolipid — mono- 
galactosyl diglyceride and digalactosyl diglyceride — levels are not 
marked for S-deficient plants but are sharply reduced in N-deficient 
plants in relation to the control. 

Figures 2 and 3 show electron micrographs of normal and S- or 
N-deficient chloroplasts at the age of 8 weeks. It can be seen that both 
deficiencies result in larger grana stacks and less stroma lamellae than 
normal maize plants. The size of osmiophilic globules is increased in 
chloroplasts from N-deficient plants (Fig. 3, B). 

Discussion 

From our studies of PS I and II activities in six types of mineral 
deficiencies (N, P, K, S, Mg, Ca) in maize, we find increased PS II 
activity in S- and N-deficiencies. Sulphur- and N-deficient plants con- 
tain chloroplasts with larger grana stacks and a proportionally larger 
amount of grana lamelle in relation to stroma lamellae (3, 9). This led 
us to investigate the lipid composition of S- and N-deficient plants re- 
ported here (Table 1), since chloroplast lipids have been implicated as 
structural components of chloroplast membrane systems. As this table 
shows we found only slight differences in the two major chloroplast 
lipids, monogalactosyl diglyceride and digalactosyl diglyceride, in S- 
deficient versus normal maize leaves but a striking reduction in the 
amount of galactolipids present in N-deficient plants. The sulfolipid 
content was also reduced up to 50% in the leaves from S- and N- 
deficient plants. Thus sulfolipid, although present in lesser amounts 
than chloroplast galactolipids, may function in the control of grana 
stacking. Since only about a third to a half of the normal amount of 
sulfolipid is present in S- and N-deficient plants while the proportion 
of grana to stroma lamellae is increased, it may be inferred that in the 
absence of the normal amount of sulfolipid stroma lamellae stick 
together more easily to form abnormally large grana stacks. Thus 
sulfolipid appears to control grana stacking in S- and N-deficient 
maize chloroplasts. 

Other agents which alter the control of grana stacking include 
light and the concentration of cations. In bright light grana stacks 
are dissociated in Amaranthus chloroplasts while in plants grown in 
dim light abundant grana stacking is present (10). In isolated 
chloroplasts grana can be dissociated into single lamellae but with the 
addition of cations reassociation occurs (11). Both of these factors may 
operate in conjunction with the lipid composition in controlling grana 
stack formation.

Enzymes of the arylsulphatase complex (Arylsulphatases A, B and C) were shown 
to be widely distributed throughout the endomembrane system of rat liver. 
Arylsulphatase C, a microsomal enzyme, was localized primarily in rough endoplasmic 
reticulum. Arylsulphatases A and B were more widely distributed. Electron 
microscope localization combined with cell fractionation studies showed the activity to 
be most concentrated in focal specializations of the bulk smooth endoplasmic reticulum 
or in lysosomes. Less concentrated enzyme activity was associated with rough 
endoplasmic reticulum, bulk smooth endoplasmic reticulum, the nuclear envelope and 
the Golgi apparatus (especially in secretory vesicles of the Golgi apparatus). 
Arylsulphatase A-B activity was not detected in mitochondria, microbodies, the plasma 
membrane and the ground cytoplasm and was low or absent from smooth 
endoplasmic reticulum of the Golgi apparatus zone. The results indicate a difference 
between Golgi apparatus-associated and the bulk of the smooth endoplasmic reticulum 
and raise the possibility of direct transfer of arylsulphatase A-B from rough endo- 
plasmic reticulum to forming secretory vesicles of the Golgi apparatus. 

The enzymes of the arylsulphatase group (aryl-sulphate sulpho- 
hydrolases, E.C. 3.1.6.1) are widely distributed among animals (1, 3, 
4, 7, 8, 10-13, 15, 17, 28, 29, 31, 32, 34), microbial (16) and plant (29) 
tissues. The importance of sulphuric acid esters in many metabolic 
processes and disorders in animals (2-5, 8, 9, 17, 27, 28) adds consider- 
able significance to the widespread distribution of the arylsulphatases. 
At least in animal tissues, the activity is largely confined to substrates 
in which sulphuric acid is conjugated with hydroxyl groups of 
phenols (Fig. 1). The inorganic sulfate released during the reaction 
can be precipitated with lead to form an electron dense reaction product. 
The latter provides a means for localizing the enzyme activity at the 
electron microscope level (1, 15, 18, 29, 34). 

At least three arylsulphatases have been distinguished on the basis 
of their kinetic properties. In rat liver, two of the enzymes, Arylsul- 
phatase A and Arylsulphatase B are considered to be localized primarily 
in the lysosome fraction (7, 8, 34). The third, Arylsulphatase C, is found 
in the microsome fraction (10, 13, 18). Yet, the precise subcellular dis- 
tribution of these enzymes in liver has never been established. The 
purpose of this study was to investigate the subcellular distribution 
of Arylsulphatases A, B and C in rat liver with particular emphasis 
on components of the endomembrane system (25).

Materials and Methods 

Male rats, 200 to 250 g, 50 days old of the Holtzman strain, 
provided with laboratory chow and drinking water ad libitum, were 
sacrificed and the livers drained of blood. The livers were removed, 
minced at room temperature and used either for determination of 
arylsulphatase activity, cell fractionation studies or enzyme cyto- 
chemistry. 

Golgi apparatus (20) and endoplasmic reticulum (6) were prepared 
as described previously. The heavy particulate fraction of Table 1 was 
obtained by collection of the band at the 1.5/1.6 M interface on a dis- 
continuous sucrose gradient used for preparation of Golgi apparatus 
fractions (22). The band was removed, resuspended in homogenization 
medium and pelleted at 3,000 g for 30 min. This fraction is largely a 
mixture of mitochondria and rough-surfaced endoplasmic reticulum.

The substrate for Arylsulphatase A-B was p-nitrocatechol sulphate 
(Fig. 1) purchased from Sigma Chemical Company, St. Louis, Missouri. 
The reaction was carried out as described by Roy (31, 32) using a sub- 
strate concentration of 30 mM and a pH of 6.0 with a reaction time of 
30 min unless indicated otherwise. 

For determination of Arylsulphatase C activity, the substrate was 
potassium p-acetylphenylsulphate synthesized from p-hydroxyacetophe- 
none and chlorosulfonic acid by an adaptation of the simplified method 
of Figenbaum and Neubert (14) for preparation of aromatic sulphuric 
acid esters. This substrate was chosen in preference to some readily 
available substances due to its relative stability toward metabolism by 
rat liver homogenates (11). Arylsulphatase C was assayed as described 
by Dogson et al. (12) with the exception that reactions were stopped 
after 30 min rather than after 1 hour. Proteins were determined by the 
biuret method. 

Tissues and cell fractions subjected to cytochemical assay for 
arylsulphatases A-B were processed according to the method of Gold- 
fischer (15), except that they were fixed overnight in 2% glutaraldehyde 
instead of being perfused as with the whole tissue experiments of Gold- 
fischer (15). The tissues and fractions were then embedded in Epon

Results 

Whole homogenates of rat liver were used in establishing assay 
conditions for arylsulphatase A-B in rat liver. The activity was ex- 
tremely stable and extracts could be stored for several months without 
loss of enzyme activity. Controls containing the enzyme solution with 
the substrate added immediately after incubation followed immediately 
by ethanol, and controls in which the substrate was incubated with 
buffer alone, were run simultaneously with experimental determinations. 



Effect of time and enzyme concentration 



Figure 2 shows the effect of incubating rat liver homogenates with 
the substrate in the presence of varying quantities of protein (Fig. 2A) 
and for varying times (Fig. 2B) under conditions of optimum pH 
(Fig. 2C) and a substrate concentration of 30mM. This substrate con- 
centration was near optimal for Arylsulphatase C (12), supraoptimal 
(inhibitory) for Arylsulphatase A (31) and yielded first order 
kinetics for Arylsulphatase B (31, Fig. 2D). There was an ap- 
proximately linear relationship between protein concentration and the 
reaction velocity over the range to 4 mg of protein in the assay (Fig. 
2A) and in subsequent studies a protein concentration of 1 mg or less 
was employed. In agreement with a previous observation (31), there 
was a decrease in reaction velocity during the first 10 min of incubation

incubation (Fig. 2B).

tion, (B) time, (C) pH, and (D) substrate concentration. The enzyme source was 
total rat liver homogenate (Table 1) frozen and thawed to release structure-linked 

latent enzyme activity. 



Effect of pH 

The effect of pH was determined over the range of 3 to 7. The pH 
optimum is that of Arylsulphtase B and was determined to be 5.7 in 
0.15 M acetate buffer with nitrocatechol sulphate as substrate (31). 
The pH optimum for arylsulphatase A is 4.7 (31). The optimum for 
Arylsulphatase C is about pH 7.2 (10, 12) 

Effect of substrate concenration 

The effect of varying substrate on reaction velocity (Fig. 2D) 
shows a hump in the curve between and 0.5 mg p~ n itrocatechol 
sulphate which is due to the presence of Arylsulphatase A (12) which 
is saturated at a substrate concentration of approximately 3 mM. As 
shown previously (12), there is no obvious substrate optimum for 
arylsulphatase B within the limits studied (Fig. 2D). 

Intracellular location 

In tissue fractionation studies, the activities of Arylsulphatases 
A and B as compared to Arylsulphatase C showed distinctly different 
distribution patterns. Arylsulphatase C appeared to be specifically 
localized in the rough endoplasmic reticulum (Table 1). Arylsulphatases 
A-B, however, showed approximately equal distribution in the rough 
endoplasmic reticulum and the Golgi apparatus (Table 1).

This distribution was confirmed and extended by the results from 
cytochemical localization of Arylsulphatases A-B. The heaviest deposits 
of lead were found over the membranes and contents of bodies attached 
to and interspersed with fields of smooth endoplasmic reticulum (Fig. 
3). These bodies may represent lysosomes but their consistent associa- 
tion with smooth endoplasmic reticulum was unexpected. More impor- 
tant in the context of the present study, lead deposits of a more diffuse 
nature were found equally distributed over the lumens of both rough 
and smooth endoplasmic reticulum (Figs. 3 and 4), the nuclear envelope 
(Fig. 4) and cisternae and vesicles of the Golgi apparatus (Fig. 4). In 
isolated fractions of rough endoplasmic reticulum, dense reaction prod- 
ucts were still present and uniformly distributed but more so over the 
membranes than within cisternal lumens (Fig. 5). With isolated Golgi 
apparatus fractions, reaction products were found over secretory 
vesicles containing lipoprotein secretory products as well as secretory 
vesicles lacking lipoprotein secretory products and presumed to repre- 
sent primary lysosomes (Figs. 6 and 7). Only small amounts of reac- 
tion product were found over Golgi apparatus cisternae and the smooth 
system of peripheral tubules (23, 24, 26). Both the isolated endoplasmic 
reticulum and Golgi apparatus fractions were free of the lysosome-like 
bodies containing dense lead deposits observed in situ (Fig. 3). 

Discussion 

In the animal tissues investigated by Goldfisher (15) and others 
(1, 34), Arylsulphatase A-B activity was largely localized in cytoplas- 
mic bodies identified as lysosomes. In contrast, Arylsulphatase C has 
been generally considered to be a microsomal enzyme (10, 18), but 
microsomes are a heterogeneous cell fraction containing membrane 
fragments of many different types of cell components. The analysis 
of arylsulphatase activity is complicated to some extent by 
anomalous kinetic properties. These anomalies have been noted 
previously (31, 32) and no clarification is provided by the present study. 

Our studies, however, do show that much of the Arylsulphatase 
A-B activity of rat liver is localized in cytoplasmic structures not 
readily identified as conventional lysosomes. Arylsulphatase A-B 
activity was about equal in endoplasmic reticulum and Golgi apparatus 
fractions. Both fractions were considerably enriched over that of the 
homogenate but the specific activity was only 0.1 that reported for lyso- 
some fractions (7, 8). Its presence in the endoplasmic reticulum and 
Golgi apparatus fractions was not due to lysosomal contamination of 
the fractions as shown by the cytochemical analyses of the isolated 
fractions (Figs. 6 and 7). 

In contrast, Arylsulphatase C activity of the Golgi apparatus frac- 
tion was only 22% that of the rough endoplasmic reticulum (Table 1). 
This value is higher than that observed with glucose-6-phosphatase and 
other endoplasmic reticulum enzymes (13 to 15%, ref. 21). One explana- 
tion for this discrepancy lies in the observation that potassium

p-acetylphenylsulphate is not a completely specific substrate for 
Arylsulphatase C under the conditions used, so that the arylsulphatase 
A and B, shown to be present in the Golgi apparatus, could account for 
the additional 7 to 10% of the activity. F. A. Rose (personal communica- 
tion) suggested that phosphate ions increase the specificity of 
p-acetylphenylsulphate for Arylsulphatase C. However, phosphate ions 
were not added to our reaction mixture. 

In the cytochemical analyses, the activity detected may be largely 
ascribed to Arylsulphatase B. Arylsulphatase A-B show a high degree 
of substrate specificity hydrolyzing p-nitrocatechol sulphate while 
splitting p-acetylphenylsulphate very slowly (31, 32). The pH optima 
of these two activities also differ. Type C Arylsulphatase has a pH 
optimum slightly over neutrality and would not be expected to con- 
tribute to the cytochemical results. At the acid pH employed, both 
Arylsulphatases A and B are active although data of Figure 2D 
suggest that, in future studies, Arylsulphatases A and B could be dif- 
ferentiated cytochemically by varying substrate concentration. 

In addition to the focal specializations of smooth endoplasmic 
reticulum (Fig. 3) and other lysosome-like bodies, we find arylsul- 
phatase activity distributed throughout the endomembrane system 
(Figs. 3 to 7). It is less evident in the smooth tubules of the Golgi 
apparatus (Figs. 4, 6 and 7) and is absent from plasma membrane, 
microbodies, mitochondria and ground cytoplasm. It is present in the 
nuclear envelope, bulk rough and smooth endoplasmic reticulum and 
cisternae and vesicles of the Golgi apparatus. This distribution is 
similar to that observed in plants where acid arylsulphatase activity 
was found in the nuclear envelope and endoplasmic reticulum with the 
lead deposits located in the lumen lying next to the membrane 
(29). Poux (29) noted lead deposits in a type of cytoplasmic body found 
in root tips of Cucumis sativus which closely resemble the structures 
illustrated in Figure 3 but which she tentatively identifies as 
phragmosomes (= microbodies, ref. 19). We found no arylsulphatase 
activity associated with microbodies in rat liver. Nor did we find 
arylsulphatases concentrated in pericanalicular dense bodies of liver 
in contrast to the report by Abraham (1). Arylsulphatase A-B was not 
found cytochemically in mitochondria. The activity present in crude 
mitochondrial fractions isolated from liver (31, 32, Table 1) may be due 
to contamination of the fraction by lysosomes and/or endoplasmic 
reticulum. 

The widespread localization of Arylsulphatase A-B in the endomem- 
brane system of rat liver raises the possibility of an active protein being 
synthesized in the endoplasmic reticulum and/or nuclear envelope and 
being transported to the bulk smooth endoplasmic reticulum or to the 
Golgi apparatus where it then becomes incorporated into lysosomes and 
other types of vesicles. Of specific interest in terms of the present study

Abstract 

The diglyceride acetate products of the acetolysis of beef heart mitochondrial 
cardiolipin were separated into three fractions, trienes, tetraenes and pentaenes, by 
argentation chromatography. Tetraenes accounted for 64 per cent of the total diglyceride 
acetates and linoleic acid accounted for 93 per cent of the total acyl residues of this frac- 
tion. There was an inverse linear relationship between the oleic and linoleic acid 
contents of cardiolipin preparations. Six diglyceride acetate fractions were obtained 
from beef heart mitochondrial phosphatidyl ethanolamine. The major fraction, tetraenes, 
accounted for 54 per cent of the total diglyceride acetates. Stearic and arachidonic acids 
accounted for 89 per cent of the acyl groupings in this fraction. There was a high 
degree of consistency in the total unsaturated fatty acid content of cardiolipin prepara- 
tions and in all diglyceride acetate fractions derived from cardiolipin. This consistency 
was also evident in phosphatidyl ethanolamine preparations. 



In a preliminary communication we reported that the fatty acids 
were nearly randomly distributed between the a - and ^-positions of 
beef heart cardiolipin (8). Argentation chromatography of the 
diglyceride acetates prepared by acetolysis of cardiolipin revealed the 
presence of three molecular species. The major species, tetraenes, 
contained more than 90% linoleic acid (8). Wood and Harlow (19), by 
gas chromatographic separation, similarly found one predominant 
diglyceride in the Phospholipase C digestion products of rat liver 
cardiolipin. In continuing our earlier studies, analyses of multiple 
cardiolipin preparations revealed a great deal of constancy in molecular 
species distribution. Further, this constancy was also observed in the 
total unsaturated fatty acid content of both native cardiolipin and the 
molecular species derived therefrom. These results are reported herein 
along with those obtained from parallel analyses of beef heart 
mitochondrial phosphatidyl ethanolamine (PE). Next to cardiolipin, 
PE contains a higher proportion of unsaturated acyl residues than do 
other beef heart mitochondrial phospholipids and contains high levels 
of arachidonic acid (1,2,6). Analysis of PE was thus of particular in- 
terest in view of the hypothesis of De Pury and Collins (4) that 
arachidonyl species are more firmly bound to mitochondrial structural 
protein than are other species. This hypothesis is correlated in part with

our recent observation that the highly unsaturated cardiolipin is tightly 
bound to cytochrome oxidase and is essential for function of the 
enzyme (1, 2). 

Materials and Methods 

Beef heart mitochondria were isolated by the method of 
Low and Vallin (10). Cardiolipin and PE were isolated from washed 
total lipid extracts (1) by preparative thin-layer chromatography (8). 
Analysis by two-dimensional thin-layer chromatography (12) revealed 
these lipids to be free of other polar lipid contaminants. To minimize 
autotoxidation, samples were stored in a nitrogen atmosphere at —20° 
C and a small amount of butylated hydroxyanisole was added to all 
solvents used. Diglyceride acetates were prepared by acetolysis at 
145° C for 40 hours in a nitrogen atmosphere according to 
Renkonen (14). In certain cases, PE was mixed with sphingomyelin 
(chromatographically pure, Sigma Chemical Company), digested with 
Phospholipase C from Clostridium welchii, and the diglycerides thus 
obtained were acetylated (14). The diglyceride acetates were first puri- 
fied by thin-layer chromatography (8) and then separated by argenta- 
tion chromatography on thin layers of Silica gel G containing silver 
nitrate (10:3 by weight). Plates were developed in chloroform contain- 
ing from 0.75 to 1.25% methanol (9, 13). Lipid bands were localized, re- 
covered (8), methylated and analyzed by gas chromatography (7). 
Relative concentrations of various diglyceride acetates was determined 
by ester analysis of the material eluted from silver nitrate plates (18). 

Acetolysis was chosen for the preparation of diglyceride acetates 
as a matter of convenience. It is known that intramolecular migration 
of fatty acids occurs under these conditions (11, 15). However, inter- 
molecular migration does not occur during this reaction (14) and, since 
positional distribution of fatty acids was not determined, the 
diglyceride acetates were suitable for analysis of molecular species 
distribution. As a check on the method, diglyceride acetates prepared 
by acetylation of the products of Phospholipase C digestion of PE (in 
the presence of sphingomyelin) gave results nearly identical to those 
obtained with the acetolysis product of the same PE sample in all 
analyses reported herein. Cardiolpin was not digested by the enzyme 
under these conditions. Although there was oxidative degradation on 
acetolysis, as evidenced by darkening of the reaction mixture, the 
colorless diglyceride acetates isolated had a fatty acid composition 
identical to that of the starting lipid. 

Results and Discussion 

Only three fractions were obtained on separation of the cardiolipin 
diglyceride acetates. The predominant molecular species in each fraction 
were trienes, tetraenes, and pentaenes, respectively (Table 1). A 
remarkably constant amount of each species was present in the seven 
mitochondrial preparations analyzed. Tetraenes were the major species 
encountered, representing 64% of the total (range 60 to 67%). In con- 
trast, a total of six fractions were obtained on argentation chromato-

graphy of PE (Table 1). Saturates (minor) plus monoenes plus dienes to- 
gether accounted for approximately 28% of the total. As with cardiolipin, 
tetraenes were the major molecular species, accounting for 54% of the 
total. There was a reasonable consistency in distribution of molecular 
species among the four separate preparations analyzed.

^Number of separate mitochondrial preparations analyzed. 

In all cardiolipin preparations, at least 91% of the total fatty acyl 
groupings were unsaturated (average 95%, range 91 to 99%) (Table 2). 
There was, however, appreciable variation in individual fatty acids 
comparing different samples, particularly with regard to the major 
fatty acid, linoleate. There was also appreciable variation among the 
individual fatty acids of each diglyceride acetate species from 
cardiolipin comparing separate preparations (Table 2). As with the 
parent lipid, there was a reasonable consistency in the total 
percentage of unsaturated fatty acids, which on the average accounted 
for over 90% of the total acyl residues in all molecular species. Linoleic 
acid was the major fatty acid in all fractions. In the tetraene fraction 
linoleate accounted for, on the average, 93% of the total fatty acids. 

Table 2 contains data on the fatty acid composition of PE and the 
more highly unsaturated diglyceride acetate fractions derived therefrom. 
As with cardiolipin, although there was variation in individual fatty 
acids, the total unsaturated acid content was nearly constant comparing 
different preparations and averaged 64% (range 61 to 68%). The major 
acids were stearate and arachidonate. This constancy in unsaturated 
acid content was also evident in the major subfractions analyzed. In 
the major species, tetraenes, stearate and arachidonate together 
accounted for approximately 89% of the total acyl residues. We had 
previously demonstrated that arachidonate is contained nearly entirely 
in the /^-position of beef heart mitochondrial PE (8). Thus it can be con- 
cluded that l-stearoyl-2-arachidonyl phosphatidyl ethanolamine is a 
major species of beef heart mitochondria. 

The diphosphatidyl glycerol structure of cardiolipin precludes 
conclusions on the molecular species distribution of the parent

phosphatide based on results obtained with diglyceride acetates. How- 
ever, the results contained herein suggest that the majority of the 
molecular species contain three linoleate molecules and further imply 
the occurrence of a molecular species containing solely linoleic acid.

The observations on the constancy in total percentage of un- 
saturated acyl residues in both PE and cardiolipin and the 
molecular species derived from them render feasible the conclusion that 
the physiological function of these lipids requires a closely controlled 
content of unsaturated fatty acids. This conclusion is substantiated by 
the observation that alterations in fatty acid composition can influence 
the properties of membranes by affecting both the attractive forces 
between lipids and proteins and the molecular packing of membrane 
lipids (4, 16).

Eichberg (5) has recently reported that nearly 50% of the cardioli- 
pin of beef heart can be isolated as a protein complex. The high degree of 
unsaturation in all diglyceride acetate species from cardiolipin may 
explain the tenaceous binding of cardiolipin to protein as being due to 
extensive interaction between the double bonds of the fatty acids and 
hydrophobic groups within the proteins. (3, 4, 17).

analysis of gas chromato grams. 



We wish to call attention to one further observation made in the 
course of these studies. Although there was appreciable variation in 
the contents of oleic and linoleic acids comparing different preparations 
of cardiolipin, there was a nearly linear inverse relationship between 
the contents of these two acids (Fig. 1). This appears to indicate that 
at least a portion of one acid may be replaced by the other in 
cardiolipin without impairment of the psychochemical properties of the 
mitochondrial membrane.

The Synthesis and Decomposition of Some Interesting 1-Pyrazolines. LEO 

Mullins, Terry L. Kruger, Theresa Cheng, and John Sharp, 
Department of Chemistry, Ball State University, Muncie, Indiana 47306. 

The synthesis of several bicyclo-1-pyrazolines through 3 + 2 cycloaddi- 

tion has been studied. The kinetics of the decomposition of a few of these 
compounds has been carried out with the identification of the decomposi- 
tion products. These studies have shown that the decompositions may 
occur by processes allowed by orbital symmetry considerations. Future 
work includes product analysis, kinetics, mass spectra, and comparison 
of photodecomposition products with thermal-decomposition products. 

Properties and Reactions of Some N, N-Diethylaniline Oxides. Terry L. 
Kruger, Nancy E. Tharp and James W. Kress, Department of Chem- 
istry, Ball State University, Muncie, Indiana 47306.— — The title com- 
pounds with a variety of ring substituents have been synthesized. The 
basicities of these water soluble compounds have been correlated in the 
Hammett Equation. These compounds undergo facile Cope elimination 
to the corresponding N-ethylphenylhydroylamines. An analysis of some 
aspects of the mechanism of this reaction and an explanation of the 
effect of substituent on both this reaction and basicity was presented. 

Synthesis and Identification of p-Benzoquinones Occurring in Arthropod 
Defensive Secretions. Joseph E. Rogers, Jr., Benjamin Fieselmann 
and James Jose, Department of Chemistry, Earlham College, Richmond, 

Indiana 47374. Eight substituted p-benzoquinones known to occur in 

arthropod defensive secretions have been prepared. Chromatographic 
methods have been explored which facilitate identification of these 
quinones in complex naturally-occurring secretions. The eight quinones 
(p-benzoquinone, methyl-p-benzoquinone, ethyl-p-benzoquinone, 2,3-di- 
methyl-p-benzoquinone, 2,5-dimethyl-p-benzoquinone, 2,3,5-trimethyl-p- 
benzoquinone, 2-methoxy-p-benzoquinone, and 2-methyl-3-methoxy-p- 
benzoquinone) were either purchased or in most cases were synthesized 
by oxidation of suitably substituted amines or phenols. The gas chromato- 
graphic behavior of these quinones has been investigated on several 
stationary phases over a range of temperatures. All but two of the 
quinones may be resolved on a five-foot by one-eighth inch copper column 
containing 2 per cent OV-17 on GC Q. Thin-layer and paper 
chromatography of the 2,4-dinitrophenylhydrazone derivatives of the 
quinones reveals that all eight 2,4DNP derivatives may be resolved on 
a silica gel layer (Eastman Chromagram K301R) upon development 
with a 3:1 chloroform :xylene solvent in the presence of aqueous 
ammonia vapors.

A Chemical Study of the White River at Muncie. Charles T. Botkin 
and Robert E. Van Atta, Department of Chemistry, Ball State Uni- 
versity, Muncie, Indiana 47306. — — Analyses for several chemical com- 
ponents of the White River are reported for a 50-day period during the 
summer of 1971. The objective of the study was to determine whether 
or not significant variations in dissolved oxygen, chloride, free and 
albuminoid ammonia, pH, calcium, magnesium, iron, and several other 
factors occurred and could be conveniently monitored in a flowing system 
of considerable volume. Results are presented for sampling points 
upstream and downstream of the city and are compared with climato- 
logical records for the sampling period. Time versus analyzed factor 
profiles are presented and, where feasible, correlated with each other and 
with other variables in the stream's composition. 

A New Experiment for Advanced Inorganic Chemistry. B. N. Storhoff 
and D. F. Storhoff, Department of Chemistry, Ball State University, 
Muncie, Indiana 47306. The utility of simple group-theoretical consid- 
erations in inorganic chemistry is well documented. The appreciation for 
such considerations has prompted the design of an experiment which illus- 
trates their utility in vibrational spectroscopy. The experiment focuses 
on the infrared active CO stretching vibrations of several manganese 
carbonyl complexes. Probable structures are assigned to the complexes 
by comparing the observed and predicted spectra. 

Rhenium(I) Complexes of 2-Cyanoethyldiphenylphosphine. B. N. Stor- 
hoff, Department of Chemistry, Ball State University, Muncie, Indiana 
47306. — Halopentacarbonylrhenium (I) (CI or Br) reacts with 2- 
eyanoethyldiphenylphosphine(L) to yield novel complexes of the stoi- 
chiometry [Re(CO) 3 LX] n . Infrared data and molecular weight data 
suggest that these complexes are dimeric and utilize L as a bridging 
ligand. The complexes react with a variety of donor solvents and ligands 
(L/) to yield complexes of stoichiometry Re(CO) 3 LL'X. 

Chelating Behavior of Some New Sterically Hindered Tetrafunctional 
Azine Ligands. John A. Scarlett and Wilmer J. Stratton, Depart- 
ment of Chemistry, Earlham College, Richmond, Indiana 47374. Two 

new unsymmetric azine ligands and their iron (II) complexes have been 
synthesized and characterized. Pyridinalpyridylphenylketazine was found 
to form two complexes as expected: [Fe 2 L 3 ]I 4 , with each ligand 
bridging two metals in a bis-bidentate fashion, and [FeL 2 ]I 2 , with trident- 
ate bonding of each ligand. Elemental analysis, infrared spectra, and elec- 
tronic spectra were used to confirm these structures. Pyridylmethylpy- 
ridylphenylketazine also forms a bridged complex, [Fe 2 L ;? ]I 4 , but ap- 
parently does not form a 2:1 tridentate complex. Attempts to produce 
the latter complex resulted only in formation of a hydrazone complex. 
A ligand hydrolysis mechanism is proposed, in which the steric effects 
of the phenyl and methyl groups cause the ligands to "squeeze" out a 
metal ion, thus allowing proton attack on the uncoordinated C=N group.

Chemistry 141 

47374. Complexes of NiCl 2 , CoCl 2 , ZnCl 2 with 2-pyridylmethylketa- 

zine, each of which had analyses indicating 4/5 or 5/6 of a ligand per 
metal, were studied in acetonitrile solution. The data obtained showed 
that the conductances of the three compounds are distinctly different. 
Empirical equivalent weights were established from the conductivity data 
for each complex. Comparison of the slopes of plots of equivalent conduct- 
ance versus square root of concentration with similar plots for two ref- 
erence compounds was used to establish the charge types of the com- 
plexes. Results for the nickel complex are consistent with a formula 
[Ni 2 L 2 Cl 3 (H 2 0) 2 ][NiCl 4 ]. Data for the cobalt and zinc complexes do 
not fit this formulation and are indicative of a more highly polymeric 
structure. 

A Counterdiffusion Study of Ferric and Silicate Ions in Agar Media. 

Jon D. Naylor and John H. Meiser, Department of Chemistry, Ball 

State University, Muncie, Indiana 47306. The development of new 

techniques for obtaining quantitative data used in the investigation of 
the counterdiffusion of ferric and silicate ions in an agar gelatin is pre- 
sented. A treatment is given of the equations used for predicting the 
location of the band precipitates at given time intervals based on the 
supersaturation theory. The authors also presented a brief historical 
account of the Liesegang Phenomenon and a review of several 
theories providing explanations of this occurence of band precipitates. 

Liquid X-Ray Diffraction Studies of the Structures of Aqueous Metal 
Nitrate, Acetate, and Perchlorate Solutions Using Overviewing Tech- 
niques. Richard M. Lawrence and Jan R. Relford, Department of 

Chemistry, Ball State University, Muncie, Indiana 47306. -Overviewing 

techniques were developed to examine the structures of liquids by x-ray 
diffraction. Viewing the entire scattering volume of a sample yields agree- 
ment between the forms of the observed and calculated scattering curves 
and permits routine calculation of a radial distribution function for the 
system. In these studies radial distribution functions were calculated for 
almost twenty aqueous solutions of silver, lead, thallium (III), mercury 
(I), and cerium (III) nitrates, acetates, and perchlorates. These radial 
distribution functions are interpreted in terms of the numbers and dis- 
tances of metal-metal and metal-oxygen interactions among closest neigh- 
bors. The mercury (I) solutions are the only solutions studied in which 
there are significant metal-metal contacts, and the results are consistent 
with the presence of Hg 2 2 + . In the other solutions studied the metal 
ions appear to be in contact with from four to nine oxygens of water 
molecules or oxy anions. The number of metal-oxygen contacts is found 
to vary in a consistent manner with the concentration of the solution and 
the nature of the cation and the anion. The metal-oxygen distances agree 
with the sums of the van der Waals radius of oxygen and the crystal 
ionic radii of the metal ions.

Brooker, Department of Chemistry, Indiana Central College, Indianap-

Laboratories. Large doses of impure para-xylene-bis (pyridinium) 

chloride when given to unanesthitized dogs produced a muscle weakness 
that progressed to complete paralysis. Small doses of the drug reversed 
the paralytic effects of d-tubocurarine. It was found that this latter effect 
was caused by an impurity present in the original salt. Attempts were 
made to isolate and identify this compound that exhibited this anticholine- 
sterase activity.

-> cholesterol, or a similar C 27 -steroid. 

From Digitalis lanata, an European plant, tigogenin(2) was isolated. 
After the incorporation of (2- 14 C) -mevalonic acid(l) the molecule showed 
the expected distribution of radioactivity : 



HO 



CH. 



CH 2 CH 2 



HO-CH 2 COOH 
(1) 




The distribution of radioactivity was determined by chemical degradation 
of the molecule. 

The cyclisation and ring closure are strictly stereospecific. One fifth 
of the radioactivity was located at C-27, while C-26 showed no radio- 
activity. To explain this stereospecific ring closure, a A 24 -steroid as 
desmosterol or cycloartenol(3) may be a possible precursor of tigogenin. 
To clarify this problem, radioactive cycloartenol(S) and cholesterol (4) 
were fed to the plants. Whereas cholesterol was incorporated, tigogenin 
showed no radioactivity after the application of cycloartenol.

These results show, that the biosynthesis of tigogenin involves the 
following steps : mevalonic acid -> squalene -> cholesterol -> tigogenin. 

Thin-Layer Gel Filtration Studies of Adenosine Deaminases from Beef 
and Beef Fetus Livers 1 . Bruce A Thornburgh and Pang Fai Ma, 

Department of Chemistry, Ball State University, Muncie, Indiana 47306. 

The chromatographic patterns of adenosine deaminase in beef liver 

and beef fetus liver showed that the enzyme exists in two forms in these 
tissues. The high molecular weight enzyme (Type A) was the predominant 
form in the beef liver and the low molecular weight enzyme (Type C) was 
the predominant form in the beef fetus liver. The Type-A enzyme was 
found to partially dissociate to the Type-C enzyme when it was rechro- 
matographed on a Sephadex column. 

A rapid method for detecting the presence of the Type-A and Type- 
C enzymes was needed to study the dissociation of the Type-A enzyme 
under various conditions. This led to the development of a thin layer gel 
filtration chromatographic technique which was applicable to adenosine 
deaminase. The technique involved the detection of the ammonia that 
is given off in the deamination reaction with Nessler's Reagent.

A Comparative Study of Adenosine Deaminase in Human Tissues. 1 
Thomas A. Magers and Pang Fai Ma, Department of Chemistry, Ball 

State University, Muncie, Indiana 47306. Multiple forms of adenosine 
deaminase were first observed and studied in many species of lower 
animals by Ma and Fisher. Three relative molecular sizes were observed: 
200,000 100,000, 30,000, and designated as enzyme forms A, B, and C, 
respectively. Evidence by Ma has shown the smallest multiple form to 
be a monomeric unit of the largest. 

Akedo, Nishihara, Shinkai, and Komatsu, have since studied similar 
multiple forms corresponding to the A and C forms in certain human 
tissues. They have reported that while normal human lung tissue con- 
tains only the A form adenosine deaminase, cancerous lung tissue 
contains both A and C forms. 

The present study enlarges the survey of multiple forms in both 
normal and cancerous human tissues. Kinetic, physical, and immunological 
parameters are presented by way of comparison of the multiple enzyme 
forms extracted from various tissues. Thin-layer gel filtration and electro- 
phoretic techniques have been applied to the study and characteristic pat- 
terns were discussed. Partial purification of the monomeric adenosine 
deaminase from the cerebrum has been achieved and pertinent data were 
reported.

Photochemical Synthesis and Destruction of Oxaziranes. M. L. Druel- 
inger and S. R. Lammert, Department of Chemistry, Indiana State 
University, Terre Haute, Indiana, 47809.— -The irradiation of a series 



144 Indiana Academy of Science 

of nitrones was studied. The compounds selected for this study possessed 
N-aryl or N-t-alkyl groups, while the nitrone carbon was either unsubsti- 
tuted (methylene) or carried a single phenyl group. The reactions were 
carried out in a nuclear magnetic resonance tube using a medium 
pressure mercury arc. In all cases the initially formed product was the 
oxazirane whose photochemical stability was dependent upon its substi- 
tuents and the irradiation wavelength. Subsequent reaction occurred via 
rearrangement to give amides or fragmentation to give nitrenes and 
carbonyl compounds. Mechanistic studies indicate a singlet excited state 
for the former and a triplet excited state for the later reaction. 



NOTE 

Some New Approaches to Teaching Chemistry for Non-Science Majors. 

Lawrence L. Garber, Department of Chemistry, Indiana University at 

South Bend, South Bend, Indiana 46615. If today's college student 

is to deal constructively with present and future social and technical prob- 
lems, he must have a basic understanding of the fundamentals of science. 
The course described here is designed to enable the non-science oriented 
student to learn some of the fundamentals of chemistry but in a stimulat- 
ing manner. To meet this objective, topics such as environmental pollu- 
tion, polymer chemistry, chemical processes important to life, and certain 
aspects of drug chemistry are used to exemplify chemical phenomena. 
The course meets for 4 hours of lecture-discussion and 2 hours of labora- 
tory work per week for 15 weeks. 

Part I of the course emphasizes properties of atoms, electronic 
structure, periodic trends, oxidation numbers, simple theories of chemical 
bonding and the rationale behind why chemical changes take place as they 
do. Part I is designed to provide sufficient background for the discus- 
sion of subsequent topics. To illustrate why Part I is necessary, consider 
the production of sulfur dioxide which is a basic air pollutant. If the 
student understands electronic sturcture and periodic trends, the student 
can very easily predict that sulfur, when combined with oxygen, can have 
an oxidation number of plus four and thus a combustion product of sulfur 
will be sulfur dioxide. This type of logic can be applied to many simple, 
yet important, reactions that occur in pollution production and abate- 
ment. 

Part II of the course emphasizes the topic of air and water pollu- 
tion which obviously cannot be extremely detailed. Five main classes of 
air pollution; sulfur oxides and related compounds, nitrogen oxides and 
related compounds, hydrocarbons, carbon monoxide, and particulate 
matter, are included in the discussion. The student is exposed to some 
of the important chemical reactions that are instrumental in the produc- 
tion of air pollutants; chemical reactions that can be potentially harmful 
to life and matter; and chemical processes that might render solutions 
to the problems. The greenhouse effect is discussed. The factors and condi- 
tions necessary for the production of smog are emphasized. 

The discussion of smog production and composition provides an excel- 
lent mechanism for the introduction of organic chemistry. The topic of 



Chemistry 145 

air pollution can be used to illustrate acid-base neutralization, chemical 
properties of acidic and basic anhydrides, pH, oxidation-reduction, colloids 
and colloidal properties. The discussion of water pollution very easily 
permits the illustration of such phenomena as ionization, electrolytes, 
solubility, hydrogen bonding and concentration units. 

Water pollution topics include a discussion of eutrophication by 
phosphates and nitrates, the chemical and physical properties and biode- 
gradability of detergents, and the essential chemical characteristics of 
phosphorous, nitrogen and sulfur cycles. A discussion of water hardness 
and the use, characteristics and effects of water softners are easily 
incorporated in Part II. The topic of mercury pollution and associated 
controversies demonstrates readily the interrelationships of inorganic and 
organic chemistry. 

Part III emphasizes organic and biochemistry. A discussion of poly- 
mers illustrates successfully some additional characteristics of organic 
compounds. A discussion of pesticides, polychlorobiphenyls and selected 
aspects of drug chemistry are also included. The characteristics and roles 
of DNA and RNA in life processes are emphasized as well as the char- 
acteristics of fats, proteins and carbohydrates. 

The laboratory is designed to supplement the lecture. For 5 weeks 
the student investigates air and water pollution. Examples of some of 
the determinations are pH, color, temperature, dissolved oxygen, dissolved 
carbon dioxide, hardness, detergent content (ABS and LAS) and 
concentrations of sulfate, phosphate, nitrate, nitrite, copper, and chloride 
ions in local water systems. Except for temperature, color and pH 
measurements, Hach chemical kits, which are specifically designed for 
each determination, are used. The advantage of using these chemical 
kits, or other commercial chemical kits, is that the reagents are pre- 
measured, the glassware is calibrated, and the detection is simple. The 
amount of substance present is indicated quanitatively by either a color 
change or a color comparison. The detection scheme is calibrated so as 
to permit direct determination of concentration without the need for 
mathematics. Hence, the result is not masked by mathematical diffi- 
culties that the student might have. All results are collected on a data 
sheet. The laboratory results help to promote considerable discussion 
and illustrate the quality of water in the South Bend area. 

In conclusion, by presenting the topics of environment pollution, 
aspects of drug and polymer chemistry and some of the essentials of the 
chemistry of life processes, important topics and concepts of chemistry 
can be discussed and learned by the student but in a more interesting 
fashion.

A Water Quality Study of the Tippecanoe River. Paul T. McKelvey, 

Tippewa Technical Institute (IVTC), Lafayette, Indiana 47905. A 

field study of water quality of the Tippecanoe River in north-central 
Indiana was conducted during June-September 1971. Surface samples 
were collected at 18 sites covering the 168-mile length of the Tippecanoe 
River from North Webster to Delphi, Indiana. Quantitative determina- 
tions were made for temperature, dissolved oxygen, total alkalinity, 
ortho-phosphate, nitrate-nitrogen, pH, and total coliform bacteria. 
Results indicated a high potential productivity due to more than adequate 
quantities of dissolved nutrient material. Total coliform bacteria counts 
were typical of small river systems flowing through both rural and urban 
areas.

Stimulation of Branch Abscission in Quercus alba by 2-Chloroethyl- 
phosphonic Acid. William R. Chaney, Department of Forestry and 
Conservation, and A. Carl Leopold, Department of Horticulture, Purdue 

University, Lafayette, Indiana 47907. Abscission of young branches 

of a mature white oak (Quercus alba) was stimulated by 1 per cent and 2 
per cent 2-chloroethylphosphonic acid in lanolin applied to the base of the 
branches. Treatments were applied 4 times at approximately 2-week 
intervals in the fall. The greatest stimulation of branch abscission re- 
sulted from treatment on September 11. Thirty-six per cent of control 
branches were shed, whereas 80 per cent of branches treated with 
2-chloroethylphosponic acid abscised. The current shoot of abscised 
branches was significantly shorter than the current shoot of branches 
retained on the tree, suggesting that the less vigorous branches were 
shed. Branches of juvenile trees of white oak did not abscise 
naturally and were not induced to abscise by treatment with 
2-chloroethylphosponic acid. 

Basin Leakage Considerations in Ecological and Hydrological Studies of 
Experimental Watersheds. H. E. McReyonlds, U. S. Forest Service, 633 

Wisconsin Avenue, Milwaukee, Wisconsin 53203. In the last two 

decades, there has been an increase in the number of ecological or hydro- 
logical watershed studies. More often, these experiments have concerned 

147 



148 Indiana Academy of Science 

nutrient cycling, water-yield, and measurements of vegetative manipula- 
tions. Basically, these studies have considered the watershed to be a 
collecting basin with a single output point. 

Too often, these watershed studies have not considered hydrologic 
"basin leakage" (i.e., interbasin imports and exports of ground water 
flow). This paper explored a number of processes by which interbasin 
transfer can occur (non-coincidental topographic and phreatic divides; 
interbasin solution tubes; intercepting pre-glacial channels; seasonal 
variations in flow direction). It appears that the basic assumptions con- 
cerning precipitation input area and piezometric flow patterns are seldom 
validated in the experimental design. 

NOTE 

A New System for Ecological Education — SEE. John W. Hart, Hayes 
Research Foundation, Inc., and Jessie M. Turner, Finley School; Rich- 
mond, Indiana 47374. Man's activities are shaping his environment; 

in turn, the environment he creates surreptitiously molds him. The indus- 
trial revolation initiated a speed up in man's ability to modify his 
surroundings. The pressures of a steadily increasing number of people, 
each demanding more and more goods and services are dictating the 
direction of movement of environmental change. That these forces are 
carrying us on a tidal wave in the wrong direction is particularly 
apparent in the developed nations of the world. We are surrounded on 
all sides by activities which degrade our environment — and hence our 
lives. Our senses are constantly insulted by noise, visual blight, dirty 
water, and stinking air, but man is a sensitive creature, and it is this 
very sensitivity which separates him from the other animals. The 
problem is not that man will not be able to adapt to this hostile 
environment. The problem is that he is doing so already, and in so doing, 
he is becoming a less sensitive organism. When man has finally lost his 
sensitivity, man has been lost. Nature may add a noble name to the list 
of animal failures. 

Education is the last hope for creating citizens who are environmental 
assets, members of a citizenry atuned to its responsibility to all living 
things on Earth. 

The system which provides the American education has for the most 
part given only lip service to the need for environmental training. An 
equally serious indictment of the system is that it Las not recognized the 
life-centered approach to learning as an exciting way to escape today's 
educational doldrums. A few innovative teachers have found that students 
can be turned on by involving them in the study of their surroundings 
and the interrelationships therein. Unfortunately the efforts of these 
teachers, while not wasted entirely, are greatly diluted by the absence of 
any continuity of environmental learning. The one shot environmental/ 
ecological learning experience may come at any level from kindergarten 
thru college, or even in that limited education after college or high school 
which we call "continuing". 

SEE, the System for Ecological Education, was created to fill the 
need for an orderly, planned, life-centered approach to education which 



Ecology 149 

will encompass the entire educational experience of an individual from 
kindergarten throughout life. SEE introduces a systematic way of 
developing in each child an understanding of environmental problems, 
their causes, solutions, and man's moral reasponsibility to solve them. 
It introduces and progressively develops concepts. At each grade level 
the student attains a more comprehensive understanding of each com- 
ponent of the environment and of the interrelationships among its 
physical and biological components. 

SEE is envisioned as a unifying framework within which the environ- 
mental inputs of all educators may become cumulative. The system, while 
designed primarily for use as a K-12 instrument, can be used to develop 
college courses for teachers, resource majors, and students of other 
disciplines. It is equally adaptable for use in adult education.

Calibration Techniques for Remote Sensing Measurements of 
Water Temperatures 1 

R. M. Hoffer and L. A. Bartolucci 2 

Laboratory for Applications of Remote Sensing 

Purdue University, Lafayette, Indiana 47907 

Abstract 

Remote sensing techniques, involving optical-mechanical scanners mounted in aircraft, 
offer great potential for meeting some of the needs for more quantitative information 
on our water (and other) resources. One technique used in remote sensing allows the 
absolute temperature of water surfaces to be determined from several thousand feet of 
altitude to within 0.5 degree Centigrade. Two methods for calibration of thermal infrared 
scanner data were described. The accuracy of these techniques was shown. The limitations 
of the calibration procedures and use of airborne scanner systems were discussed. 

Introduction 

One recently-developed remote sensing tool is a "thermal infrared 
optical-mechanical scanner" or "thermal IR scanner." This instrument 
can be mounted in an aircraft and flown over an area of interest, thereby 
allowing one to obtain a temperature map of the area below the aircraft. 

Calibration Techniques 

To make thermal IR scanner data meaningful, the relative radiance 
values (as measured by the scanner) must be related to the true tempera- 
ture of the area being sensed, or target area. Two quite different tech- 
niques are possible. These are 1) the correlation method, and 2) the 
internal calibration techniques. 

The correlation method is relatively simple, but does have some 
serious drawbacks. Variations in tone on the thermal IR imagery corres- 
pond to relative differences in the radiant temperatures of the scene 
imaged. Therefore, if the actual temperature of the various objects on 
the earth's surface can be determined, it is possible to correlate these 
measurements with density values of the imagery to those points on the 
ground. To use this technique for water studies, temperature measure- 
ments must be obtained for a number of locations on the river or lake at 
the time the aircraft passes overhead. Later, these measurement points 
are located on the thermal IR imagery and the density of the film at these 
points is measured. In this way, correlation is possible between actual 
temperature of the water at a few points and the film density at these 
same points. Intermediate film density values can then be interpolated. 

The major drawbacks to this technique are that, 1) it takes only a 
few minutes to obtain the scanner data via airplane, but it may take

several hours to obtain surface temperature measurements, during which 
time the water temperature may have changed significantly, and 2) 
development of the film on which the data are recorded is subject to many 
possible variations in chemical processing which can sometimes cause 
tonal differences to not have a linear relationship. 

For several years, the correlation method was the only technique 
available, due to limitations in the thermal IR scanning equipment. 
Relatively recent developments in scanning equipment have allowed 
researchers to devise an "internal calibration" technique, which, with 
two assumptions, allows the actual water temperature to be determined 
directly from the scanner data, and no surface observations of tempera- 
ture are necessary (other than to verify the reliability of the technique). 
One assumption is that the radiation characteristics of water in the 
thermal IR region approximate those of a black-body radiator (which 
is defined as an object that will completely absorb all frequencies of 
radiation incident upon it). Water departs only 2-3% from being a perfect 
black-body radiator in these thermal IR wavelengths (1). The second 
assumption is that atmospheric attenuation has relatively little effect 
on the amplitude of the signal received at the scanner. This assumption 
is based on the fact that the 8.0-13.5^m region of the electromagnetic 
spectrum is in an atmospheric window (where absorption by the various 
components of the atmosphere is minimal), and also that most of the small 
amounts of energy absorbed by water vapor or other atmospheric constit- 
uents would be reradiated by the water vapor since water acts as a black- 
body in this portion of the spectrum, thereby allowing only extremely 
small net losses of radiated energy between the water surface and the 
aircraft scanner. Previous work has indicated that these assumptions 
appear to be reasonable (3). 

The data used by LARS in this work was obtained by a multispectral 
scanner, owned and operated by the University of Michigan, and mounted 
in a C-47 aircraft (4). This scanner has been modified to accommodate 
two reference black-bodies which are viewed by the scanning mirror 
during each revolution. These reference sources are referred to as calibra- 
tion plates, and are temperature controlled, one plate being cooler than 
the other, in approximately the same range of temperatures of the earth 
surface features over which the aircraft is flying (2). 

Methods 

The objective of this study was to determine the reliability of the 
temperature calibration procedures using data collected over the Wabash 
River at two different times of the year, and under somewhat different 
weather conditions. On June 30, 1970, data were collected from an alti- 
tude of 3,000 feet at 10:45 am, with good clear weather conditions, while 
on August 13, the altitude was 2,000 feet, with somewhat hazy weather 
conditions and at 3:47 PM. 

Using the data logs on the calibration plate temperatures, the data 
were calibrated for radiant temperature and gray scale maps were 
produced. The different temperature ranges were depicted by different

Wabash River (from right) is shown. Note that the June 30 data shows that the water

to the river were displayed. A blank, or no symbol, was used for all other 
temperatures. 

Results 

The junction of the Tippecanoe River (from left) with the Wabash 
river (from top) is illustrated in Figure 1. On June 30, the actual water 
temperatures, as measured from the boat, showed very good correlation 
with the temperatures indicated by the calibrated scanner data. Note that 
the Tippecanoe River was approximately 1.2°C cooler than the Wabash, 
and that this temperature difference persisted for a considerable distance 
downstream. On August 13, the Tippecanoe was relatively warmer than 
the Wabash, but the calibrated scanner data indicates about 0.8°C lower 
temperatures than were actually measured. Since the August data were 
obtained under hazy conditions, this could be the cause of the calibration 
error, and would indicate that additional work is required to obtain a fully 
reliable calibration technique. 

Note that on the June 30 data only the river areas are shown on the 
printouts, indicating that only the water occupied the temperature ranges 
indicated, but on August 13, considerable land areas were emitting the 
same amounts of energy as the water. This indicates that if one is to 
produce temperature maps showing only the water areas, a layered classi- 
fication scheme will need to be developed whereby one first identifies all 
water areas, and then maps the temperature characteristics of the water 
only.

Natural Areas in the Beech-maple and Maple-basswood 
Forest Regions of Nine States 

Linda K. Escobar* and Alton A. Lindsey 

Department of Biological Sciences 
Purdue University, Lafayette, Indiana 47907 

Abstract 

Four hundred and eighty-two natural areas of biological or geological interest are 
now reported within the Beech — maple and Maple — basswood Regions of the 9 states which 
include these forest regions. 

In Indiana, 8 forested natural areas and 17 tracts of other types were previously 
unpublished. Of the former, the Womer Tract, Bryan Memorial Preserve and Burgdorf 
Woods are described briefly. 

In 1969-70 the National Park Service commissioned 5 theme-studies 
at as many ecological laboratories in the eastern and central United 
States, to obtain data from secondary sources for later use in designating 
many new National Natural Landmarks. The basis for organizing this 
overall survey was the forest region map inside the back cover of Braun 
(1950). Our contribution (3, 7) was a study based largely on correspond- 
ence, interviews and published sources, of the two forest regions domi- 
nated by sugar maple. The Maple-basswood region is confined to parts 
of Illinois, Wisconsin and Minnesota, whereas Beech-maple occurs in 
New York, Pennsylvania, Ohio, Michigan, Illinois, Wisconsin, and Indiana. 
The literature cited consists of 204 titles. 

The concept of natural areas and the rationale and techniques of their 
description and preservation were presented in references 2, 4, 5, 6, 7, 
8 and 9. W. B. Barnes has written popular descriptions in "Outdoor 
Indiana" magazine of most of the 17 areas in the state system of nature 
preserves, of which he is the Director. 

We acknowledge with thanks the information about "new" Indiana 
stands received from William B. Barnes, Mrs. Thomas E. Dustin and 
Floyd Swink. Among the multitude who helped provide data for other 
states condensed into Table 1 we are especially indebted to Drs. Grant 
Cottam, J. Arthur Herrick, Kenneth S. Erdman and William Tans. 

Summary for the Two Entire Regions 

A table of data giving only one line for each of 482 tracts of land was 
prepared, but proved too voluminous for publication. A more generalized 
summary, given in Table 1, categorizes areas by the single natural 
feature of special interest, usually the one constituting the chief reason 
for considering the site worth preserving. Those of the 9 states for which 
Table 1 shows few tracts are not deficient in natural areas if the whole

state were considered, but, rather, are states having little acreage of the 
two of Braun's vegetational Regions that we studied for this project. The 
larger tracts are often state parks, wildlife areas or metropolitan parks, 
that possess a great diversity of natural interest in addition to recrea- 
tional facilities. These are listed as "large, varied" areas. Since our bias 
as ecologists is toward communities, there is much more of geological 
interest encompassed in the sites than is reflected by the table. (Prac- 
tically all the Beech-maple stands occupy land that has been glaciated, 
for example). The line for "Other geology" includes mostly waterfalls. 
The tracts considered under "Gorges, bluffs" very often contain relict 
hemlock colonies. Caves and archaeological sites were omitted. Even 
though several or many natural features were present, a site is listed only 
once; therefore, the numbers and totals are significant.

present study.

Nearly all the good natural areas and nature preserves in Indiana 
had been described in Lindsey, Schmelz and Nichols (6). Additional Indi- 
ana tracts reported to the NPS by the present authors are also 
included in Table 1.

Indiana Areas Previously Unpublished 

Further details on "new" Indiana natural areas are given in Table 
2 for forests and Table 3 for tracts where the principal feature is not the 
tree community, if any. 

The largest and most diversified of the new Indiana nature preserves 
is that donated to the State System of Nature Preserves in 1970 by Mr. 
and Mrs. John Womer of Chicago. It is 4 miles south of Chesterton and 
1 mile east of Rt. 49 on Rd. 750 N. It is in two parts lying a quarter-mile 
apart on rough land of the Valparaiso moraine. The upland supports a 
disturbed oak woods, and, in much of the north 80, early lumbering left 
open conditions now showing early successional stages with scattered 
small trees and shrubs. About one-third of shallow Carlson Pond lies 
within the southern 80. There are also 2 small kettle ponds, and a former 
pond nearly as large as Carlson Pond is now a large depression supporting 
buttonbush and willows. In the southern part of the south 40, about 10 
acres of a mixed forest appear to be essentially undisturbed except for 
an o!d woods road. 

The Eunice Hamilton Bryan Memorial Nature Preserve is also within 
the state system under Director William B. Barnes. It was bequeathed 
by the late Henry R. Smith of Rossville, and named in honor of the mother 
of Mrs. Smith. The tract was previously known as Smith Woods. The area 
is notable for many large old trees and includes several permanent ponds 
which, in April, occupy about 6 of the 29 acres. The soils are Crosby and 
Brookston. Table 4 gives data on vegetational attributes of the oak- 
hickory stand on high ground away from the pond edges, and indicates 
that the major dominant, white oak, had more than double the import- 
ance value of shagbark hickory. Irrespective of species, the average acre 
of the 4 acres (contained within the 0.2 acre sampling strips) showed 101 
individual trees over 4 inches diameter at breast height. These trees on 
the average acre had 117 feet basal area, which is high for Indiana 
forests. In the 4 acres within the sampling strips, species that had one 
or more individuals in the 30-inch or larger size class were white oak, red 
oak, swamp white oak, beech and bur oak. There were 29 such trees 
sampled, including 18 white oaks, ranging up to the 46-inch size class 
which had two individuals. The largest red oak was 38 inches and the only 
swamp white oak measured 42 inches. 

Burgdorf Woods, in the extreme southwest corner of Vanderburgh 
County, has only 10 acres of large, old-growth timber, which is surrounded 
by woods of lesser quality. It represents the Oak-hickory type, with 
stratum ranks as follows for trees exceeding 4 inches dbh — red oak 
(including Shumard's) 7, black oak 6, tulip tree 6, white oak 5 and white 
ash 5. The species with some stems exceeding 30 inches dbh were Shu- 
mard's red oak with 13 such stems, black oak had 10, tulip tree 7, white 
oak 5, white ash 3, and sugar maple, sycamore and bitternut hickory 
with one each. In all reproduction strata, sugar maple dominated 
substantially. Twenty-three species had stems exceeding 22 inches dbh. 
Of the 142 larger trees measured in the 10 acres, 95 exceeded 22 inches.

Abstract 

White ash (Fraxinus americana) , hop hornbeam (Ostrya virginiana) , red oak 
(Quercus rtibra) , yellow poplar (Liriodendron tulipifera) and beech (Fagus grandifolia) 
exhibited importance per cent values of 49.4, 37.4, 28.6, 26.5 and 20.3 respectively, for 
a 10-acre forest located on the Brookville Ecology Research Center in southeastern 
Indiana. These values represented 54 per cent of the total tree species 
sampled within an area which had recently been released from browsing. White ash, 
hophornbeam, sugar maple (Acer saccharum) , redbud (Cercis canadensis) and honey 
locust (Gleditsia triacanthos) were represented by a high density of seedlings (< 1 inch 
Diameter Breast Height), while canopy species of yellow poplar, red oak, beech and 
bitternut hickory (Carya cordiformis) were poorly represented in smaller size classes. 

Introduction 

Systematic sampling of a forest area following removal of cattle 
reveals much quantitative information regarding secondary succession. 
Cattle prefer tender grasses, forbs and herbs, in addition to shoots and 
tree seedlings (6). Effects of browsing also include such physical changes 
as compaction of soil, promotion of erosion, damage to root systems, litter 
removal, and general degradation of the natural seedbed conditions (6). 
Although several recent studies have been concerned with deciduous 
forests in this region of the midwest (2, 7, 8, 11), only limited information 
is available regarding the effects of browsing on the composition of for- 
est communities. Thus far, only the study by Day and DenUyl (3) has 
provided specific information on browsing pressures by cattle in Indiana 
forests. We attempted to better measure and evaluate the effects of 
browsing on the composition of a mature deciduous forest community 
located in southeastern Indiana. 

Study Area 

The study area is located in Union County, south of Liberty, Indiana, 
specifically in the NW 1/4, Sec. 22, TUN, R2W on the Fairfield, Indiana, 
Quadrangle. The site is included within the Brookville Ecology Research 
Center, administered by Miami University, Oxford, Ohio, and Earlham 
College, Richmond, Indiana. The actual study area was comprised of 10 
acres of forest located on the 140-acre research station leased in 1969 from 
the Army Corps of Engineers. The remaining 130 acres had been used 
annually for agricultural crops (e.g., corn, soybeans, etc.) until the spring

of 1970. The total area had since been left undisturbed to proceed through 
secondary succession. The 10-acre forest area had been periodically grazed 
by a herd of cattle for at least the past 8-10 years. This herd ranged in 
size from 6-15 cattle and was permitted to graze this area periodically 
during the spring and summer months out of each year. Cattle were 
permanently removed from the study site approximately 3 months before 
sampling was initiated. 

The forest is located on a gradual-moderate slope with a total relief 
of 140 feet from the highest to lowest points and lies just north of the 
Wisconsin glacial boundary. The physiography is defined as Dearborn 
Upland, a dissected plateau north and west of the Ohio River with 
streams in deeply incised valleys (12). Soils for this area have been 
reported by Alfred, Ulrich and Zachary (1). Climatic conditions for this 
area have also been previously described by Schaal (10). 

Methods and Materials 

The nested quadrat method was used for sampling the vegetation 
(9). This method provides adequate sampling within a community of vary- 
ing plant sizes. Ten nested quadrats, each 66 feet by 66 feet (0.1 acre 
each), were placed randomly within the 10-acre forest area. Thus, 10 per 
cent of the total forest area was sampled. Each 0.1-acre quadrat 
contained one 6.6 feet by 66.0 feet plot (0.01 acre) and two 6.6 feet by 
6.6 feet square plots (0.001 acre or 1 milacre). 

During October, 1970, all trees greater than 3 inches in diameter 
breast height (dbh) were tallied in the 0.1-acre plots. All saplings over 
12 inches in height and less than 3 inches dbh were tallied in the 
0.01-acre plot and all seedlings less than 12 inches in height were tallied 
in each milacre plot. The number of trees per acre, relative density, 
frequency of occurrence, relative frequency, total basal area, relative 
cover, and importance per cent values were computed (9). Frequency 
distribution of all species was computed by size classes. Diameter 
measurements of all trees were rounded to the nearest inch. Basal area 
for each species was calculated using a conversion table (9). 

Results and Discussion 

White ash (Fraximus americana) , hop hornbeam (Ostrya virgini- 
ana), red oak (Quercus rubra), yellow poplar (Liriodendron tulipfera) , 
and beech (Fagus grandifolia) were clearly dominant, having impor- 
tance per cent values of 49.4, 37.4, 28.6, 26.5, and 20.3, respectively. 
These species constituted 54% of all tree species sampled. (Table 1). Hop 
hornbeam, usually a mid-canopy species in white ash-yellow poplar-red 
oak associations (5) was the most frequently encountered species. White 
ash, red oak, yellow poplar, and beech, the major canopy species, had 
relative cover values of 20.7, 18.9, 13.6, and 12.8%, respectively, repre- 
senting approximately 66% of the total cover (see Table 1). 

The above-mentioned dominant trees (i.e., white ash, hop hornbeam, 
red oak, yellow poplar, and beech) exhibited maximum dbh measure- 
ments of 18, 9, 34, 31, and 23 inches, respectively. Other large trees in-

eluded black cherry (Prunus serotina) , sugar maple (Acer saccharum), 
sassafras (Sassafras albidum), shagbark hickory (Gary a ovata) , and 
bitternut hickory (Carya cordiformis) , with maximum dbh measure- 
ments of 18, 17, 16, 15, and 12, respectively. Such major canopy species 
as red oak, beech, bitternut hickory, yellow poplar, and black cherry were 
not well represented in the small size classes (< 5.0 inches dbh), nor in 
the seedling class. The paucity of reproduction of the major canopy species 
may be due to the influence of livestock. Species dominating the mid- 
canopy were redbud (Cercis canadensis), slippery elm (Ulmus rubra), 
sugar maple, hawthorn (Crataegus crux-gallii) , paw-paw (Asimina tri- 
loba) and wafer ash (Ptelea trifoliata) . 

Seedlings present were mainly white ash (78,500/A), hop hornbeam 
(54,000/A), redbud (9,500/A), honey locust (Gleditsia triacanthos) 
(8,500/a) and sugar maple (6,000/A). Slippery elm and blue ash 
(Fraxinus quadrangulata) exhibited a seedling density of 1,500/A each. 
Five taxa with 500/A seedlings each were sassafras, blue beech (Carpinus 
caroliniana) , osage orange (Madura pomifera) , chinkapin oak (Quercus 
muehlenbergii) , and sycamore (Platanus occidentalis) . 

In an earlier study concerned with browsed Indiana forests Day and 
DenUyl (3) reported that seedlings of white ash, sugar maple, and 
slippery elm were selected by cattle under all browsing intensities, 
whereas, under light to moderate browsing (i.e., 10 or more acres per 
cow), red oak, beech, sassafras, bitternut hickory, sycamore, honey locust, 
and black cherry were selected. They also reported that seedlings utilized 
under heavy to very heavy browsing conditions (i.e., less than 4 acres 
per cow) included shagbark hickory, hawthorn, blue beech, hophornbeam 
and paw-paw. Comparing the results of Day and DenUyl (3) to those of 
this study, it would appear that this forest had been under moderate 
browsing stress due to the paucity of red oak, beech, bitternut hickory, 
and black cherry seedlings. 

DenUyl, Dillen and Day (4) reported that white ash, slippery elm, 
and sugar maple were found to be prolific seed producers. This, perhaps, 
helps to explain much of the data in the present study, in which white 
ash, slippery elm, and sugar maple were represented by 27, 9, and 6 mature 
trees per acre, respectively, as well as each exhibiting an abundance of 
small seedlings. 

In summary, the disturbance (browsing) of this forest community 
was clearly reflected by an absence of reproduction (seedlings) of over 
50% of the dominant canopy species. It appears that certain dominant 
species based on importance per cent values (e.g., red oak, yellow poplar, 
and beech) were adversely affected by browsing. It also appears that 
white ash and hop hornbeam are able to maintain their dominance even 
under moderate browsing stress. The reason for this browsing selection 
factor awaits further investigation.

Abstract 

Food item volume percentages were determined of the contents of 207 adult and 84 
juvenile wild turkey droppings collected over 4 seasons. 

Material found in order of decreasing volume percentages was Gramineae seeds; soil 
and organic debris (including grit); unidentified plant material (leaves and stems); insect 
parts; various seeds of Quercus sp., Cornus sp. and Smilax sp. 

The Gramineae constitutes a large portion of the diet over all seasons with the large 
seeds from small woody species being important only in the fall and winter. 

Insects probably are not a large part of the diet of either adult or juvenile wild 
turkeys. 

Introduction 

The eastern wild turkey (Meleagris gallopavo silvestris Vieillot) dis- 
appeared from northern Indiana by 1870 and from southern Indiana by 
1900 (2, 4, 7). The regrowth of forests and the increased protection due 
to hunting laws and management programs has allowed the successful 
re-establishment of this species in Indiana. In 1956, wild turkeys from 
Arkansas were released on the Crane Naval Ammunition Depot in Martin 
County and later releases of wild turkeys from Missouri were made in 
other parts of southern Indiana between 1962 and 1966. Wild turkey 
populations are now established at Brown County State Park, Clark State 
Forest (Clark, Scott and Washington Counties), Harrison County Turkey 
Management Area in the Harrison-Crawford State Forest, Lost River 
Area of Hoosier National Forest (Martin and Orange Counties), Mogan 
Ridge Turkey Management Area of the Hoosier National Forest (Perry 
County), Owen-Putnam State Forest (Owen and Putnam Counties), and 
Pike State Forest (Pike County). 

Indiana wild turkey management programs may extend the present 
range. Markley (8) and Webb (11) have noted that the shortage of food 
may be a factor limiting wild turkey populations. Food habits of the 
re-introduced wild turkey in Indiana have not been studied. These data 
may be used by game biologists in future management programs. 

This study concerned the food habits of the wild turkey in southern 
Indiana. Dropping analysis was used to determine the food habits because 
an adequate sample of crop and gizzard contents was unavailable for 
analysis due to the low populations and minimal hunting take.

Methods and Materials 

Wild turkey droppings were collected by Indiana game biologists in 
unglaciated portions of Clark, Harrison, Perry, and Monroe Counties. 
Sex and age of the wild turkeys producing the droppings were determined 
according to dropping size and shape (1, 6). Contents of droppings were 
separated and identified following procedures outlined by Korschgen (5) 
and Eaton, Moore, and Saylor (3). All remains from a given season and 
age class were pooled to obtain total volume. Food item volume percent- 
ages were then based on the total sample volume (6, 9). 

Results 

A total of 291 wild turkey droppings (collected between January 1968 
and January 1971) was examined in this study. Food item volume per- 
centages of the dropping contents are listed by season for adults in Table 
1 and for juveniles in Table 2. 

Plant seeds from the Family Gramineae constitute a major portion 
of the diet throughout the year for both juvenile and adult birds. Plant

2 Desmodium sp., beetle feeces, and reptile scales. 

Seeds from Cornus sp., Quercus sp. and Smilax sp. are most 
abundant in the droppings collected during the fall and winter, and 
appear to constitute a large part of the diet during those months. 

Insects are not a significant part of the annual diet of adult Indiana 
wild turkeys, but appear to be slightly more important to juvenile birds. 
Schorger (10) reports that insects form the most important food of young 
wild turkeys, but this study indicated that few insects are ingested by 
juveniles.

ABSTRACTS 

Insects and Other Arthropods of Economic Importance in Indiana 
During 1971. R. W. Meyer and J. V. Osmun, Department of 

Entomology, Purdue University, Lafayette, Indiana 47907. -The 

abundance and activity of insects and other arthropods that were im- 
portant to growers of foods, fibers, or animal products, or were 
destructive of stored products, or were annoying to man in the state 
of Indiana during 1971 were reviewed, together with notes on 
non-economic arthropods that were of interest. 

Survival of Odonata Naiads Through Drought and Freezing. B. Elwood 
Montgomery, Department of Biology, Frostburg State College, 

Frostburg, Maryland. Living Odonata naiads were found in a "dry" 

pond in late October (October 28, 1968). They were in damp situations 
— masses of fine roots or accumulations of debris on the exposed bottom 
surface. The natural environment was restored within a few days of 
the initial observations by fall rains. 

During the following winter an examination of the pond 
revealed that all water was frozen, but the bottom surface immediately 
beneath the ice was not. 

No naiads could be recovered from the pond following the fall rains 
which resulted in extensive marshy margins so that the central area 
of the pond could not be approached. Sampling was difficult in the 
spring for the same reason. However, naiads of Zygoptera (none of 
which had been found the previous fall), Aeshnidae and Libellulidae 
were collected. These were of such age that development from the egg 
during the spring appeared extremely improbable. Thus, the naiads must 
have survived the elimination of all water from their habitat twice — 
once through drought and, then, by freezing. 

Myiasis in Delaware County, Indiana, 1971, with a Confirmed Case of 
Infestation by Wohlfahrtia vigil (Walker) (Diptera: Sarcophagidae). 

R. E. Siverly, Department of Physiology and Health Science, Ball State 

University, Muncie, Indiana 47306. Two fly larvae were removed 

from the leg of a rabbit on July 25. One of these larvae was reared to 
the adult stage. The pupal period required 12 days. The adult was 
identified by the U. S. National Museum as Wohlfahrtia vigil (Walker). 

Wohlfahrtia is known as a specific myiasis producer, and the larvae 
are reported to invade unbroken skin in children, as well as in young 
animals. Death has occurred in animals as a result of secondary 

171

bacterial infection. This species evidently has extended its range into 
Indiana from the north. 

Another case of dermal myiasis occurred in a very old and feeble 
dog. Larvae of Phaenicia sericata (Mg.) and Phormia regina (Mg.) 
were recovered from the frontal head region on August 26. 
Identification of these flies was confirmed in the adult stage. 

It is doubtful if primary screwworm occurs in this area; however, 
a survey is planned in 1972 which will solicit the cooperation of 
veterinarians in Indiana for early reporting of all myiasis cases, so 
that accurate species determinations can be made, and follow-up studies 
conducted at sites where actual infestations occur. 

Preliminary Investigation of the Effects of Three Hormonomimetic 
Compounds on Larvae of Culex pipiens pipiens (L.) (Northern House 
Mosquito). Steve Betras and R. E. Siverly, Department of 
Physiology and Health Science, Ball State University, Muncie, 
Indiana 47306. The effects and lethal dosages of three hor- 
monomimetic agents were investigated during the summer of 1971. Tests 
with Stauffer (R-20458), Monsanto (Mon-0585), and Zoecon (ZR-0515) 
were conducted, using late instar larvae of Culex pipiens pipiens ob- 
tained from waste lagoons in Delaware and Henry Counties. All three 
compounds were juvenile type hormones. 

Larvae were exposed to the chemicals by dissolving the compounds 
in acetone and mixing these solutions with lagoon water in which larvae 
were collected. Each sample consisted of 20 larvae in 100 milliliters of 
filtered lagoon water. Control samples were set up with filtered 
lagoon water alone. From three to five levels of concentrations were 
used on each trial, with from three to five replicates for each level of 
concentration. 

Effective dosages were much higher than the manufacturer's recom- 
mendations for each compound. This was believed due to rapid 
biodegradation of the chemicals in lagoon water. 

R-20458 and Mon-0585 produced a total kill during a 48-hour 
exposure at 40 and 30.5 parts per million, respectively. ZR-0515 
produced complete kill at 15.5 parts per million with a 24-hour exposure. 
Most of the tests were difficult to evaluate because of the high 
mortality in the controls. The Zoecon product appeared more active, 
but less stable than either the Stauffer or Monsanto compounds. Further 
laboratory investigations should be conducted before actual field testing 
of these compounds is attempted. 

A Preliminary Study of Autogeny and Host Preference of Culex pipiens 
pipiens L. (Northern House Mosquito) in East-Central Indiana. Donald 
A. Shroyer and R. E. Siverly, Department of Physiology and 

Health Science, Ball State University, Muncie, Indiana 47306. 

Several colonies of Culex pipiens pipiens L. were established from 
immature stages collected at two food processing waste lagoons to 
evaluate the effects of photoperiod on the expression of autogeny and 
on host preference. 



Entomology 173 

Three cages were maintained under a 15L 9D photoperiod, at 80° 
Fahrenheit ± 2°. One cage was provided no blood host and produced no 
egg rafts after several weeks. All dissected females from this cage were 
nongravid. 

A second cage was provided only avian hosts, while a third was 
offered mammals. Although Culex pipiens pipiens is regarded as pri- 
marily an avian feeder, samples from both cages contained 
equivalent proportions of engorged females. However, females fed on 
birds produced more eggs than those fed on mammals. 

Two colonies were maintained under a 13L 11D photoperiod. One 
cage was provided a bird host and the other a mammal. There was no 
evidence to support the shorter day length as conducive to mammal 
feeding, since samples from both cages contained equivalent proportions 
of engorged females. 

Further studies to clarify the effects of photoperiod on host 
preference and autogeny will be conducted by: 1) observations of lab- 
oratory colonies under simulated natural light conditions but constant 
temperatures, 2) observations of laboratory colonies under simulated 
hibernating conditions, and 3) studies of natural overwintering popula- 
tions in the field. 

Genetic Studies on Melanic Forms of Tropisternus collaris (Fabricius) 
from North and South America. Frank N. Young, Department of 

Zoology, Indiana University, Bloomington 47401. Laboratory studies 

of the results of crossing melanic Tropisternus collaris from South 
America with the melanic subspecies from Florida and South Carolina 
indicate higher levels of interfertility than shown in crosses with the 
lightly pigmented North American forms. Rearing of larvae from wild 
caught females from South Carolina show that interbreedings of light 
and melanic forms occur in nature. Further evidence for the discreteness 
of the genes producing the melanic condition was presented. 

The Planipennia (Neuroptera) in Indiana. H. Randolph Lawson, 
Department of Entomology, Purdue University, Lafayette, Indiana 
47907. — — Representatives of nine families (Coniopterygidae, Mantis- 
pidae, Berothidae, Hemerobiidae, Polysteochotidae, Sisyridae, Chry- 
sopidae, Ascalaphidae, and Myrmeleontidae) were recorded in this study. 
Representatives of the eighteen species previously recorded in litera- 
ture as occurring in Indiana were collected during the summer of 
1969. Twenty species were reported as being new records from 
Indiana. Due to inadequate taxonomic work on the species of the 
family Coniopterygidae, specimens of this family were identified only 
to genus. Five genera of coniopterygids were recorded. 

The possible occurrence of 17 more species which have been re- 
corded from adjacent areas is reported. Included in these possible 
species is Nallochius americanus (McLachlan) which represents a 
10th family, Dilaridae. Therefore, a total of 55 species is included in 
the keys constructed for adult identification. 



174 Indiana Academy of Science 

Important range extensions include Micromus variolosus Hagen, 
a western species of Hemerobiidae, and Brachynemurus longicaudus 
(Burmeister), an eastern, south-eastern coastal species of Myrmeleon- 
tidae. 

The only recorded species of the family Polysteochotidae in the 
eastern U. S., Polysteochotes punctatus (Fabricius), appears to have 
had a drastic population decline since the early 1900's. Although 
collected quite often in the Chicago area around the turn of the 
century, no specimens have been seen that were collected after 1940.

Indiana State Records and Notes on Some Rare 
Butterflies and Skippers in the State 

Ernest M. Shull 

402 N. Wayne Street 

North Manchester, Indiana 

Abstract 

As the result of collecting butterflies in the state from 1964 to 1971, six species, 
Thymelicus lineola (Ochsenheimer) , Polites mystic (Scudder), Autochton cellus 
(Boisduval & LeConte), Erynnis baptisiae (Forbes), Euristrymon Ontario (Edwards), 
and Polygonia satyrus (Edwards), have been added to the butterfly fauna of Indiana. 
In addition to the new state records, the following rare species were collected: Euphyes 
dukesi (Lindsey), Satyrium caryaevorus (McDunnough) , and Pieris napi oleracea. 

Family Hesperiidae 

Thymelicus lineola (Ochsenheimer) European Skipper 

I collected one male June 22 and one female July 1, 1967, in a grassy 
pasture, North Manchester, Wabash County. In recent years I have 
collected lineola in LaGrange, Elkhart, Kosciusko, and Wabash 
Counties (3). Pairs in copula have been taken in June, suggesting that 
this species has become well established in Indiana. 

Polites mystic (Scudder) Long Dash 

I collected the first Polites mystic in the state on June 6, 1969, 
Mongo Bog, Mongo, LaGrange County, only seven miles from the 
Michigan border (6). It is now fairly common in Wabash and 
Kosciusko Counties. June 10, 1970, I found a colony of this species in 
a bog by Lake Waubee, Milford, where Iris versicolor was its favorite 
food flower. 

Autochton cellus (Boisduval & LeConte)— — Golden Banded Skipper 

Single specimen was collected by my son, James D. Shull, June 7, 
1970, in Brown County State Park, near Nashville, Indiana (7). 

Erynnis baptisiae (Forbes) — Wild Indigo Dusky Wing 

August 27, 1970, I collected a female near its food plant 
(Baptisia tinctoria) in a field near North Manchester but in 
Kosciusko County (7). 

Euphyes dukesi (Lindsey) Dukes' Skipper 

Mr. Homer F. Price, Payne, Ohio, collected one male July 24, 1962, 
in Steuben County (2). I collected one more June 27, 1970, North 
Manchester, Wabash County (7). 

Family Lycaenidae 

Satyrium caryaevorius (McDunnough) Hickory Hairstreak 

I collected a pair June 22, 1968, on a hickory tree leaf in 
Kosciusko County (5). Caryaevorus is uncommon in Wabash and 
Kosciusko Counties in June and July. 

175 



176 Indiana Academy of Science 

Euristrymon Ontario (Edwards) Northern Hairstreak 

Collected the first specimen July 12, 1967, on dogbane flowers, 
North Manchester, Wabash County (4). Each year a few have been 
collected in Wabash County from late June to about mid-July. 

Family Nymphalidae 

Polygonia satyrus (Edwards) — — Satyr Angle Wing 

June 25, 1969, I collected this essentially western species in 
Kosciusko County, Indiana (6). It is uncommon, rare, or absent from 
late May through July in Wabash and Kosciusko Counties. 

Family Pieridae 

Pieris napi oleracea Harris — Mustard White 

Blatchley (1891) reported this species from Kosciusko County, in 
the summer of 1890 (1). Old records are unreliable as napi was often 
confused with virginiensis. 

July 12, 1971, John Campbell, a high school student in my collecting 
party, collected one in Mongo, LaGrange County. On August 24 John 
Campbell and I returned to Mongo, where we collected 23 more napi. 
It should be looked for elsewhere in the state. 

No doubt other rare Indiana species could be added to this report, 
but Mr. S. Sidney Badger, Jr., of Woodland Hills, California, and I have 
just completed a comprehensive annotated list of the butterflies of 
Indiana, 1971, therefore I have limited this paper primarily to a listing 
of my own state records.

Aggregations of Chalybion calif ornicum (Saussure) (Hymenoptera : 
Sphecidae) near Centerville, Wayne County, Indiana 

Gertrude L. Ward 

Joseph Moore Museum 

Earlham College, Richmond, Indiana 47374 

Abstract 

Observations over a 5-year period of aggregations of Chalybion californicum 
(Saussure) near Centerville, Indiana, indicate a preference by this wasp for a western 
exposure on wooden buildings. The wasps were found at the nighttime roost sites, in 
varying numbers from about June 1 to September 30. A peak in numbers was reached 
between June 14 and June 28, with a second, but much lower peak coming from 6 to 
22 days later. The highest number counted was 260 on June 26, 1971. 

Introduction 

Clusters of animals are of interest to biologists for several reasons. 
Sleeping aggregations permit easy population censusing. Aggregation 
is of interest as a precursor of social development, of particular sig- 
nificance when occurring in an otherwise solitary species. Finally, there 
is little understanding of the stimuli which initiate grouping and which 
hold groups together. 

Aggregations of the blue wasp, Chalybion californicum (Saussure), 
were observed over the 5-year period from 1967 through 1971 near 
Centerville, Wayne County, Indiana. Observations extended from June 
1 to October 1. 

Over the years, several explanations have been offered for clusters 
of animals. In 1916, Fabre (5) thought that the cluster of several 
hundred wasps, Podalonia hirsuta (Scopoli), which he found sheltering 
under a stone might be resting migrants. After studying the sleeping 
habits of a Florida butterfly, Heliconius charitonius L. (=//. chari- 
thonia L.), Jones (7) argued the pros and cons of group protection. 
He observed that when one insect was disturbed the whole group was 
warned, but also found that a predator could gorge on the collected 
insects if they were unwary or slow to move. He saw no sexual 
significance in grouping. Evans and Linsley (4), observing bees and 
wasps of several species, found no clear adaptive value in sleeping 
aggregations. However, in clusters of the digger wasp, Steniolia 
obliqua (Cresson), which Evans and Gillaspy (3) observed for 5 years, 
mating behavior was evident. Evans believed that the clustering served 
a social function leading to mating. 

Allee's (1) interest in aggregations is well known. After referring 
to some accidental animal groupings such as New England corals and 
the animals on a wharf piling he said, "Other close aggregations occur 
as a result of the less spectacular trial and error reactions, in which 
the animals wander here and there, more or less vaguely stimulated 
by internal physiological states or external conditions, and so come to 
collect in favorable locations." The effect of one external condition,

temperature, on the choice of an aggregation site was described by El 
Rayah (2) for 2 tenebrionid beetles, Adesmia antiqua Klug and 
Pimelia grandis Fabricius. He found that A. antiqua aggregated in a 
zone of 34-38 °C and P. grandis gathered in a zone of 28-34° C. 
Chalybion zimmermanni Dahlbom which P. Rau (10) saw in Mexico may 
have been responding to temperature. Rau found about 20 of these blue 
wasps clustered on a piece of rope in a shed where a 75-watt 
incandescent lamp burned until midnight. 

Hamilton et al. (6), after studying an aggregation of starlings 
(Sturnus vulgaris L.), devised a model of a refuge with a core at the 
center representing the nighttime roost, and two dispersal areas around 
it. They believed that the expenditure of time and energy required to 
fly from the core to the outer range was balanced by the lack of 
competition in that area. Applying this model to C. californicum, the 
nighttime roost is the core, the nest area lies in the inner dispersal area, 
and the feeding area is the outermost range. 

An aggregation pheromone was isolated from the southern pine 
beetle, Dendroctonus frontalis Zimmermann, by Payne (8). He found 
that the chemical was emitted in the frass by female beetles and was 
attractive to both males and females of the same species. 

Variations in the numbers of Chalybion californicum at nighttime 
roosts were reported by Rau and Rau (11) and by P. Rau (9) from 
Missouri and Kansas. For example, 30 wasps were found on the under- 
side of an overhanging rock near the Meramec River in the vicinity of 
St. Louis, and 100 or more wasps were found in an open cow shed in 
the middle of July at Lake View, Kansas (11). Near Wickes, Missouri, a 
group of more than a thousand were in the eaves of an abandoned 
house. Another group slept in a niche of a pillar and a third group 
entered a hollow tile on top of a brick chimney (9). 

In New Jersey, Weiss (12) found a group of C. californicum 
clustered at night on the same inside corner of a cloth awning for 5 
summers. These were on the southwest side of a dwelling (personal 
communication). Leland Chandler (personal communication) reported 
that a group of C. californicum roosted on the west-facing side of a shed 
near Otterbein, Indiana. 

It seems possible that the initial choice of a roost or refuge by C. 
californicum may be based on temperature. The continued use of a roost 
then may be reinforced by a pheromone or some other odor-producing 
material. 

Results of Observations 

The wasps started gathering at the main roost site in east-central 
Indiana about June 1 and several could be found there until the middle 
of September. Roosting began about 2 hours before sunset, and the last 
wasps had settled by about an hour after sunset. During the period of 
settling they would fly off if an observer approached within 3 feet. 
Counts were made after dark when the wasps were not disturbed by

the beam of a flashlight. In the morning the wasps were often still in 
place until 2 or 3 hours after sunrise. They were active earlier on warm, 
sunny days than on cool, cloudy days. 

At one favorite roost site, an old privy, a Fahrenheit ther- 
mometer was fastened close to where the wasps spent the night. 
Temperature was recorded each time a count was made. When tempera- 
ture at the roost site was compared with that on the north side of a 
nearby building, the roost site was warmer by 4°F. 

Over the 5-year period several roost sites were used. The main site 
favored by most of the wasps changed from the west side of the privy 
to the west side of a tool shed (Fig. 1). The tool shed was about 7 feet 
east of the privy and the roost site under the eaves was about 4 feet 
higher than the former site. Sunlight reached the new site for several 
minutes longer each day. 




Figure 1. Aggregation of Chalybion calif ornicum (Saussure) on west side of tool shed 
near Centerville, Indiana, on night of June 15, 1970. 



Early in June 1971 a few wasps were found on the north side of 
the tool shed just under the peak of the roof, and a few were on the 
southeast corner of the shed. As the summer progressed wasps disap- 
peared from these sites and more accumulated on the west side. A few 
also appeared around a seldom-used light socket on a porch ceiling and 
also under a loose shingle on the south side of a building about 5 feet 
north of the tool shed. The shingle gave some protection from the 
weather and, at the end of the summer, wasps were found here in small

numbers after they had disappeared from the main site. For example, 
the last wasps were seen on the west side of the tool shed on September 
9, 1971, but one was found under the shingle as late as October 1, 1971. 

Two peaks in numbers of wasps occurred in each of the 5 years. 
Except in 1969, the first appeared in June and the second in July. In 
1969, both peaks were in June. During the study, time between peaks 
varied from 6 to 22 days (Table 1). During 3 summers, counts were 
made of female C. calif or nicum working on nests in the tool shed and 
other buildings, but there was no correlation of these counts with counts 
of the roosting wasps. The number of nesting wasps was always low, 
about 5 to 10.

No predation on the wasps by birds was observed at the roost sites 
over the 5-year period, although birds which are known to eat wasps 
were in the vicinity. The extent of predation away from the roost site 
was not investigated. 

Aggregations were made up of both males and females. No mating 
behavior was observed at the roost sites. 

Small deposits of fecal matter were found at the roost sites. These 
were not tested for presence of a pheromone because techniques for the 
analysis of such small amounts of material were not accessible. 

Conclusions 

1) It is believed that the warmer temperature at the main roost 
sites on the west sides of 2 wooden buildings was the initial stimulus 
for choice of sites. 



2) Peaks in numbers of wasps at the roost sites occurred from 7 
to 28 June, over a 5-year period. 

3) Peak numbers of wasps varied from 16 to 260. Second but lower 
peaks varied from 13 to 16 and followed from 6 to 22 days later. Some 
of the second peaks were higher than some of the first peaks of other 
years.

Observations of Halictus confusus Smith (Hymenoptera: 
Halictidae) on Woodland and Field Flowers 1

Abstract 

The native bee {Halictus confusus) has been recorded from at least 165 host plant 
species. Observations were made of a local nest population for 4 years. These indicated 
that the flowers visited by bees during the warm months of the year reflected availability 
and, possibly, selectivity. Events of 1964 were typical and are reported. 

Spring beauty {Claytonia virginica L.), toothwort (Dentaria laciniata Muhl.), dande- 
lion {Taraxacum officinale I.), and winter cress (Barbarea vulgaris R. Br.) were visited 
most frequently during April and May. Nectar and pollen were obtained principally from 
white clover (Trifolium repens L. ) and red clover ( T. pratense (Mill.) Schreb. ) during 
the summer period of nest expansion. 

The native bee, Halictus confusus, is a polylectic species with a 
wide range of floral hosts throughout the growing season in the eastern 
United States (3). While studying the ecological life history of this 
species at the Purdue University Entomological Research Area near 
West Lafayette, Indiana, in 1964, observations were made of the 
interrelationship of a nesting population of H. confusus and plants 
having conspicuous flowers within 200 yards of the nesting site from 
April to October. 

Although H. confusus has been recorded on at least 165 species of 
plants (1, 2, 3), this extensive floral record does not reflect the utiliza- 
tion of regional flora by a local nesting population. In the results re- 
ported here, only 22 plant species were frequented in the forage area 
by the bee colony investigated, and only 6 species were considered 
important to colony nutrition (Table 1). 

During April, the newly-emerged queen bees showed a marked 
preference for spring beauty (Claytonia virginica L.) in the woodland 
areas adjacent to the colony site on a field hilltop. At this time, the trees 
were still without foliage and the forage area of the woodlands was 
well lighted in favorable weather. Most of the floral visits to spring 
beauty were for nectar to be used in personal nutrition, although several 
observations of pollen feeding and one sighting of pollen collection on 
the scopae were recorded on this plant. Pollen collection was indicative

(Dentaria laciniata Muhl.), which bloomed at the same time and in the 
same areas, was also visited by the females but to a lesser extent.

As these woodland flowers waned in late April, the bees shifted 
suddenly to dandelion (Taraxacum officinale (L.) Weber) as this flower 
attained a conspicuous bloom in the fields near the nesting site during 
the last week of April and the first few days of May. The visits to 
dandelion blossoms were primarily for personal nutrition. About the 
first week of May, winter cress (Barbarea vulgaris R. Br.) began to 
bloom in large conspicuous stands in nearby orchards and fields. As 
it became common, H. confusus females deserted the dandelions and 
for the next several weeks were found on the blossoms of this plant 
during favorable weather. Coincidentally, provisioning of brood cells 
in the nests became commonplace as this floral species began to bloom. 
The pollen and nectar collected from winter cress probably provided 



184 Indiana Academy of Science 

more than 95% of the material from which the pollen balls of the first 
brood were fashioned by the overwintered females. By the end of the 
third week in May, the last utilization of this plant was witnessed as 
it entered a fruiting stage. 

During late May, flowers in the nearby fields and orchards were 
scarce and the bees were observed spending more time than usual in 
the field, presumably searching for the few winter cress blossoms still 
left or looking for alternate sources of nutrients. At this time, the long- 
est flights of 1964 took place with 10 flights for pollen, taking from 
60 to 138 minutes, whereas the seasonal average was about 30 minutes. 
At this time, single observations were recorded for mouse-ear 
chickweed (Cerastium vulgatum L.) and blackberry (Rubus sp.), 
suggesting that a search for a preferred floral host was in progress. 

At the conclusion of this period of flower scarcity, the females 
became inactive and the nests became sealed as the adults remained 
in the nests with their developing broods. This period extended from 
May 26 to June 6, 1964. As the first brood-worker females emerged, 
conspicuous flowers were in bloom in the forage areas, such as yarrow 
(Achillea millefolium L)., daisy fleabane (Erigeron strigosus Muhl.), 
and white daisy (Chrysanthemum leucanthemum L.). Although a few 
visits were recorded to these composites (white daisy visited by H. 
confusus on June 5, 1965), the summer workers favored white clover 
(Tri folium repens L.) and red clover (T. pratense (Mill.) Schreb.) as 
the major sources for nectar and pollen during the June and July nest 
expansion and provisioning period. During this time, Halictus ligatus 
Say, a related species coexisted with H. confusus by nesting in the same 
nesting site. However, interspecific competition was apparently avoided 
in part by preference of floral hosts since H. ligatus was common on 
the flowers of yarrow, daisy fleabane, and white daisy and uncommon 
on white clover and red clover, just the opposite of H. confusus. 

Halictus confusus adults were observed 1 to 3 times only on redbud 
(Cercis canadensis L.), shepherd's purse (Capsella bursa-pastoris (L.) 
Medic), hop clover (T. agarium L.), white sweet clover (Melilotus alba 
Desa.), wild rose (Rosa sp.), yellow sweet clover (M. officianalis 
(L.) Lam.), horse nettle (Solanum carolinense L.), wild carrot 
(Daucus carota L.) in the order first observed in the field. 

In late summer and fall as clovers became scarce, the newly- 
emerged males and females fed on the available flowers, such as 
Japanese clover (Lespedeza lineata (Thumb.) H. and A.) and white 
heath aster (Aster ericoides villosus (Mich.) Voss). Since these females 
were destined to be the overwintering brood, they did not construct cells 
and collect pollen provisions. 

The only other nutrient observed to be collected by H. confusus 
was perspiration, presumably for the salt content. Although Stevens 
(4) reported this species to be a common "sweat bee" in North 
Dakota, the behavior of "sweat bees" in feeding on the perspiration of 
one's bare skin was not observed in H. confusus, nor could it be induced. 
In the nesting site, Dialictus imitatus (Smith) and a larger species, 



Entomology 185 

probably D. zephyrus (Sm.), were common "sweat bees" on hot and 
humid days but were not joined by H. confusus individuals. The manner 
in which this species fed upon perspiration was to land on artificial 
objects that had been handled such as stakes, paper bags, etc., and feed 
upon the perspiration residue. There was one record of a female 
H. confusus hovering about the eyes of the observer for several 
minutes in the manner of an eye gnat. 

Some species of flowers seemed to be visited for nectar only. In 
central Indiana, five species of milkweed were observed to have 
male and female bee visitors for nectar only. Whorled milkweed 
(Asclepias verticillata) was quite attractive to H. confusus during 
midsummer in the general Lafayette, Indiana, area. Both sexes trans- 
ported pollinia in interblossom transfer, but these were never found 
in pollen balls within a nest.

Northern Indiana was rejuvenated in the Pliocene producing a gently 
rolling landscape with moderate relief. The La Porte Valley and 
Elkhart Valley, two buried valleys, reflect this. Two of three ice lobes 
which penetrated Indiana produced the presently visible glacial features 
during the Wisconsin's Cary substage. Some features' depositional his- 
tories have multiple explanations while those of others are more 
evident. One interpretation of the St. Joseph River's present course in- 
volves piracy of the headwaters of the ancient Kankakee River. The 
pebble lithologies of various deposits show the underlying bedrock type; 
there are differences between outwash and till pebble analyses. Some 
percentages may possibly serve as indicators in distinguishing a lobe's 
deposits in this area. 

Age and Correlation of Middle Devonian Strata of Jasper County, 
Indiana. R. William Orr and William D. Rebuck, Department of 
Geography and Geology, Ball State University, Muncie, Indiana 47306. 

—Outcrops of Middle Devonian strata in south-central Jasper County, 

near Rensselaer, were examined and collected for eonodonts as part of 
a continuing study of conodont biostratigraphy of Middle Devonian 
rocks of Indiana. Jasper County exposures consist of mostly fine-to- 
medium grained, dark gray, vuggy dolomite, which lithology is also ex- 
hibited by correlative subsurface strata to the south in White, Tippe- 
canoe, and Warren Counties. Conodont faunas of the studied outcrops 
are dominated by specimens of the important platform genera 
Icriodus and Polygnathus and contain as late Middle Devonian zonal 
indicators I. latericrescens latericrescens and P. varcus s. I. Middle 
Devonian strata of Jasper County represent a southwestern dolomitic 
facies of the Traverse Formation of the Michigan Basin and lie within 
the P. varcus Zone high in the Middle Devonian. These beds correlate 
with the upper (sub-Squaw Bay) part of the Traverse Group of 
Michigan, the upper part of the Traverse Formation of northern 
Indiana, and the Beechwood Member of the North Vernon Limestone 
of southern Indiana and the Illinois Basin.

Structural Control of Cavern Development in Northwestern Washington 
County, Indiana. Richard L. Powell, Department of Geosciences, 

Purdue University, Lafayette, Indiana 47907. Most caverns in the 

outcrops area of limestones of Mississippian age in south-central 
Indiana consist of passages that trend down the local dip of the bed- 
rock. Generally, the regional structure is reflected by numerous 
caverns or subterranean drainage routes which divert surface karst 
drainage westward or southwestward to outlets or springs along en- 
trenched surface streams. The gradient of the subterranean passages 
is generally compatible with the local rate of dip of the bedrock, some- 
times dissecting progressively lower strata if the cave stream gradient 
exceeds the rate of dip. A few cavern passages parallel the strike of 
the strata, usually owing to a steeper hydraulic gradient to a surface 
outlet. Examples of subterranean drainage in an updip direction are 
rare, if not nonexistent, in Indiana. 

Several caverns have been surveyed in the drainage basin of Clifty 
Creek, in northwestern Washington County, Indiana, which exhibit sub- 
terranean drainage contrary to the southwestward regional trend. These 
caverns have commonly developed eastward in a down-dip direction on 
the east flank of the southernmost nose of the Leesville Anticline. They 
are tributary to Clifty Creek, a partially strike-oriented, deeply en- 
trenched stream. River (Wet Clifty) Cave is mostly a strike- 
oriented, northward flowing cavern, a subterranean headward exten- 
sion of Clift Creek. This example of cavern development in adjustment 
to local structure is proof of the importance of structural control to the 
initiation and development of subterranean drainage. 

To Harmonize a County A Proposed Integrated Study of Vigo 

County, Indiana. John H. Cleveland, Department of Geography- 
Geology, Indiana State University, Terre Haute, Indiana 47809. The 

finite nature of a region's natural resources, combined with ever in- 
creasing demands upon them, produces a conflict between man and his 
environment that may lead to extinction, or at best, radical change for 
both. Challenged by the writings of Indiana "geoecologists" Guernsey, 
Wayne, and Patton, a comprehensive pilot study of Vigo County is 
underway to form the orderly framework of information necessary for 
viable courses of action now to avert future tragedy. The project will: 
1) compile and catalogue the extensive data and sources represented 
by federal, state and local governmental agencies, educational and 
research institutions, and business enterprises; 2) outline and undertake 
research projects of both short and long term duration to fill in the in- 
formation gaps; 3) develop "dynamic equilibrium equations" for the 
local ecosystem; and 4) disseminate this information to the public and 
to the decision makers. As an illustration, coal resources are examined. 

It is believed that this continuing study will aid in justifying our 
existence, enhance teaching and research capabilities, and of most im- 
portance, aid in rational progress towards a dynamic equilibrium with 
his environment of man's choosing, permitting a quality survival of both 
for a significant fraction of geologic time.

46383. Regional populations and their optimally related natural and 

human resource patterns considered in their total environmental 
perspectives — social, economic, political and spiritual — may be said 
to be the basic geographic principle of evaluation of human behavior 
and life's motivations. 

Ethnic and economic concerns of man are necessarily space-related 
and resource-oriented, whatever the stage of cultural development may 
be. Hence, the study of human ecology of the environment in sequent 
occupance form has been traditionally considered a comprehensive chal- 
lenge to the geographer. 

Despite historic antecedents and present-day research and teaching 
concerned with the basic qualities of the environment, the field of 
geography today occupies a comparably inferior professional position 
in the area of Environment Management. 

This paper explored the reasons for this condition and suggested 
some remedial measures establishing professional and public recognition 
of geography as a distinctly environmental behavior science. 

Factors Associated with the Decline of Central Place Functions On the 
Rural Poor of Monroe County, Indiana. Steven K. Pontius, Geography 
Department, University of Minnesota, Minneapolis, Minnesota 55455. 

Between 1910 and 1970 the number of small towns and villages in 

Monroe County, Indiana, providing the essential retail and service 
activities has declined from 31 to 2. The result of this decline has 
spatially isolated many rural residents who previously were within 2 
miles of such a village anywhere in the county. To those individuals 
who have transportation this is of little or no concern. 

However, to over 100 of the 294 low-income households inter- 
viewed, which represents a 20% sample of all low-income rural residents 
in Monroe county in 1965, the ramifications are great. They represent 
people who have no means of transportation. Characteristically these 
people are 65 or older, have lower incomes, fewer jobs, poorer housing 
conditions, and who are spatially more isolated from the remaining 
central places than the low-income people interviewed who had trans- 
portation. 

The consequences associated with their isolation, due to their lack 
of transportation and their household location in relation to the 
remaining central places are: the inability to supplement their income, 
and thus the inability to maintain their homes, buy nutritious food, 
and acquire preventive medical care. And, saddest of all is that because of 
this spatial isolation, some of these people give up in despair, stay 
home, and become more isolated from the world. In reality they exist 
in a sort of solitary confinement. 

The Relationship of Expensive Residential Dwellings to Hilly Terrain.

Urbana, Illinois 61801. A field study indicated no statistically signif- 
icant relationship between expensive residential dwellings and hilly 
terrain in the City of Valparaiso, Indiana. The concept of "hilliness" was 
quantified through the use of the local relief within designated study 
sectors. The mean true value according to the Assessor of randomly 
selected homes within each sector was used to quantify "expensiveness". 
Analysis using Pearson's Correlation Coefficient r, the Chi Square test, 
and other tests, all failed to substantiate the hypothesis that expensive 
homes would be found in hilly areas. 

Fulmendosa River: A Multipurpose Irrigation Project in Sardinia. F. P. 

Kallay, Geography Department, Valparaiso University, Valparaiso, 

Indiana 46383. One of the great engineering triumphs of modern man 

has been his ability to transform acres of barren land into arable areas of 
large scale productivity. Such a transformation is occurring in the south- 
west portion of Sardinia, known as the Campidano, an area which is 
already an intensively cultivated portion of the island, but possessive of 
much greater agricultural potential. This potential will be realized in the 
form of a vast project known as the ENTE AUTONOMO DEL 
FLUMENDOSA (EAF). 

The major purpose of the EAF is the utilization of the hydro-electric 
basin of the Flumendosa River and its tributaries. In addition to provid- 
ing water for irrigation purposes, the EAF project will supply water for 
the capital city of Cagliari and several surrounding communities. Fur- 
thermore, it will provide hydroelectric power at an annual average of 80 
million kilowatt hours. 

The effects of the entire EAF project will not be known in their 
totality for several more years, but it is safe to say that the effects will 
be far-reaching for the island of Sardinia and will have numerous bene- 
fits on the Italian economy as a whole as well. 

Coal Age Tree Stumps in Indiana. D. L. Dilcher, Botany Department, 

Indiana University, Bloomington 47401. During the spring of 1971 

the Paleobotany class of Indiana University located three casts of Sigil- 
larian trunks apparently standing in place where the trees once grew. 
These were found exposed in the No. 5 pit at the Hawthorne strip mine 
of Peabody Coal Company. Several more trunks were located during the 
summer and one was collected by the Indiana State Natural History 
Museum before mining was stopped in the area. The nature of the trunks, 
positions, size and relationships were discussed and a photographic record 
of them was used to illustrate the talk.

Earth Dam Problems — and the Geological Site Investigation

Abstract 

There are many small man-made lakes in Indiana and a few large reservoirs with 
dams over 100 feet in height. The major problems encountered in the construction and 
operation of these structures are seepage around or through their fills, permeability or 
weakness of foundation bedrock, unsuitable construction materials, instability of 
natural slopes, subsidence of dam or pool into caverns or mine voids, and tectonic activity. 
Faulty construction is not within the scope of this paper. To minimize structural 
inadequacies or failures caused by these problems, the design engineer must be forewarned. 
An adequate detailed design investigation must be conducted by a capable geologist. The 
geologist must review all available data relative to the site, study, test and sample the 
features of the site, submit samples, test data and his interpretations to the soil mechanics 
laboratory, and present all this information and the laboratory report to the design 
engineer. 

Introduction 

Multi-purpose use of stored surface water has increased greatly in 
recent years. Problems in dam construction, operation and maintenance 
have kept pace. 

In Indiana most dams for water storage have been constructed with 
earth. The type of earth material is dictated by the type of dam, the site 
features and the available material. 

Problems are encountered during construction and while the reservoir 
is in operation. The purpose of the geological dam site investigation is 
to discover the problems so that they may be offset by adequate design. 

Simply expressed, a dam must be strong enough to hold back a given 
volume of water. The permeability and strength of the dam and its abut- 
ments are important factors in the successful operation and maintenance 
of the reservoir. 

Pre-design investigations of dam sites vary in intensity. The larger 
and more elaborate the structure, the more detailed must be the investiga- 
tion. The compilation and review of data on dam failures or deficiencies 
has largely determined the steps taken in current dam site investigations. 

The causes of inadequacies in all earth fills reported prior to 1952 
have been placed in the following order (5) : 



1) 


Overtopping 


30% 


5) Slope paving 


5% 


2) 


Seepage 


25% 


6) Miscellaneous 


7% 


3) 


Slides 


15% 


7) Unknown 


5% 


4) 


Conduit leakage 


13%

Most of the dams referred to in this study are large structures. The 
writer believes that most of the problems could have been foreseen had 
an adequate pre-design been employed. 

Overtopping usually occurs when the dam has insufficient height 
or when the outlet structure is inadequate. This design deficiency usually 
results from inaccurate hydrologic data. In recent years the science of 
hydrology has become much more reliable and overtopping is no longer 
a common event. 

Based upon the writer's experience and study of recently constructed 
earth dams in Indiana, the following order for problems encountered is 
listed as follows : 

1) Seepage in overburden or fill 3) Bedrock incompatibility 

2) Foundation weakness 4) Miscellaneous. 

Seepage occurs through permeable fills, abutments and/or founda- 
tions. This leakage results in water loss and, frequently, piping of fine 
soil materials in fill or adjacent natural ground. Poorly graded (well 
sorted) sands and gravels are common offenders. Abutment or foundation 
seepage may occur through layers or lenses of sands and gravels in 
glacial drift or in alluvial sediments. Fills constructed chiefly with 
coarse-grained earth materials are subject to seepage. Conditions con- 
ducive to either of these possibilities must be recognized in the 
pre-design investigation. Permeable materials are important components 
of a good fill, but must be used with silts and clays. 

Soft and compressible foundations will consolidate during or after 
construction. Weak soils located at the base of the dam must be found, 
sampled and tested. Such weak materials must be either treated or 
removed. Standard penetration tests, conducted during the site investiga- 
tion, pin-point weak foundations. Undisturbed samples of the weak 
material, as indicated by standard penetration tests, are collected and 
submitted to a soil mechanics laboratory for test data. These data 
determine the proper solution for the design engineer. 

Shale, sandstone and limestone are the bedrock possible to encounter 
during the construction of dams in Indiana. 

Shale is generally impermeable and of adequate strength. Slides and 
creep occur on hillsides where shale is near the surface. Some shales swell 
when wet and shrink when dry. Propensity to cause slides or to swell or 
shrink must be noted in the investigation report. 

Sandstone is generally strong and relatively impermeable. Some sand- 
stones are weakly cemented and are therefore permeable, weather 
rapidly and are often weak. When permeability or strength is in question, 
adequate testing must be done. 

Limestone, when massive and not jointed, provides a good foundation 
and basin for dams. Cavernous, open and jointed limestone presents prob- 
lems in maintaining water levels in the reservoir and in making secure 
the embankment and structural works. When limestone is suspected of 



Geography and Geology 193 

being permeable, the bedrock is usually pressure-tested in place. Core 
samples may be subjected to testing to determine stability. 

There are numerous miscellaneous problems that may result in the 
inadequacy or eventual failure of a reservoir if not discovered in the 
investigation and allowed for in the design. 

Lack of and/or insufficient suitable embankment material may 
present a serious problem. Sands and gravels, to the exclusion of fine 
grained soil, or vice versa, are unsatisfactory fill materials. 

Haul distance is an important factor in determining the economics 
of borrow operations. In the construction of the moderate size dams of 
from 20 to 50 feet of fill height, borrow must be available within 1/4 
mile. 

Proper placement of fill, proper compaction and satisfactory moisture 
control are necessary to avoid construction and operation problems (6). 

Steep slopes and shallow soils combine to present slope stability 
problems. During construction, care must be exercised to prevent distrub- 
ing slope equilibrium. Unloading the toe of a natural slope may be inviting 
disaster. Saturation of an otherwise stable slope can also cause a slide. 
The disaster at the Vaiont reservoir in Italy is an example (3). 

Subsurface mining and subsequent subsidence can ruin a dam or its 
impounded pool. Underground voids resulting from the pumping of oil 
is believed to be a major contributor to the failure of the Baldwin Hills 
Reservoir in California (4). Subsidence from coal mining or from oil 
pumping are not known to have caused damage to dams in Indiana 
although there is ample reason for concern. 

Problems related to tectonic activity have not yet been reported in 
Indiana. One study of the location of earthquake probabilities indicates 
that southwestern Indiana is an area of concern (1). There are known 
and suspected fault areas in the state, many of which appear to be related 
to the Mt. Carmel fault. 

To minimize the hazards related to site problems a pre-design geo- 
logical investigation of the site is mandatory. This should be planned by 
and carried out under the direction of a qualified geologist. Minimum 
requirements for this investigation appear below. 

First, all available published or unpublished data relative to the site 
should be assembled and reviewed. One source of these data is the Indiana 
Geological Survey. 

Second, an adequate subsurface investigation must be carried out 
in conjunction with a study of all surface features of the site. Field test- 
ing, sample collection, and complete and accurate reporting of the site 
conditions are necessary parts of this requirement (2). 

Third, the samples collected must be submitted to a soil mechanics 
laboratory for testing, analyzing and reporting. 



194 Indiana Academy of Science 

Fourth, the geologists report and the laboratory report must be 
delivered to and interpreted for the design engineer. An important part 
of these reports is a recommendation for further study, if necessary. 

Fifth, the geologist should make periodic visits to the site after 
construction has begun to compare conditions actually encountered with 
those anticipated as a result of the pre-design investigation. 

It is my opinion that a well-conceived and an economical site 
investigation will uncover virtually all adverse site conditions likely to 
result in dam inadequacies and possible failures.

Glacial Stratigraphy of the Fort Wayne Area and the Draining 
of Glacial Lake Maumee 1 

N. K. Bleuer and M. C. Moore 

Indiana Geological Survey, Blooming-ton, Indiana 47401 

Abstract 

Two major glacial till sequences are present in the Fort Wayne area. The upper 
sequence consists of the clayey tills of the Lagro Formation and the lower consists of 
extremely hard loam tills that are correlated with the Trafalgar Formation. Both are 
Wisconsinan in age. 

The morphology and development of the Fort Wayne Outlet, the Six Mile Creek 
channel, and the Wabash-Erie Channel were controlled by a combination of bedrock topog- 
raphy, early glacial discharge routes, the lithology and thickness of glacial materials, and 
the most recent ice-controlled drainage. 

The morphology of the lake floor and the morphology and postglacial stratigraphy 
of the outlets of glacial Lake Maumee suggest that all three of the classic lake levels could 
have discharged at Fort Wayne and that the classical 800-foot, 760-foot, and 780-foot 
sequential order is without foundation. The lower hard tills could have slowed 
temporarily the downcutting of the Fort Wayne Outlet and stabilized the intermediate 
lake level. 

Introduction 

An ongoing study of the environmental geology of the Fort Wayne 
area, Allen County, Indiana, has required that we develop much more 
detailed knowledge of the glacial stratigraphy than has been known here- 
tofore. Therefore, we have accumulated a considerable amount of data 
in the form of water well records, engineering boring logs, shallow refrac- 
tion seismic records, measured sections of natural and artifical exposures, 
and logs of our own power augering. Our synthesis of these data is just 
beginning, but we wish here to outline some of the new information by 
giving a basic stratigraphic framework for the area and a more detailed 
description of the outlets of glacial Lake Maumee and then to point out 
some of the ramifications regarding accepted concepts of glacial and 
glacial lacustrine history. 

Past Work 

Until the present study, the most recent geologic work in the Fort 
Wayne area was done as a part of the Indiana Geological Survey's regional 
geologic mapping program. The surficial geology shown on the "Geologic 
Map of the 1° x 2° Fort Wayne Quadrangle . . ." (G. H. Johnson and 
S. J. Keller, in preparation) does not differ significantly from that mapped 
by earlier workers (Fig. 1). 

The first comprehensive work in this area, the "Report upon the 
Geology of Allen County," by C. R. Dryer, M.D. (3), has gone virtually 
unchallenged to this day. And even it, in part, summarized work by 



Publication authorized by the State Geologist, Department of Natural Resources,

A report on "The Roads and Road Materials of Allen County," by J. A. 
Price (10), included a colored l:250,000-scale surficial geologic map, which 
is still a valuable tool. The synthesis of this geology into the regional 
interpretation of glacial history was done by Leverett (8) and Leverett 
and Taylor (9). There are very few areas in the Midwest whose glacial 
geology was better known before 1915 than was the glacial geology of 
this area. And as is true for so many other areas, virtually no 
morphologic or stratigraphic work has been done since the time of 
Leverett and Taylor. 



Bedrock Topography and Preglacial Drainage 

Situated on the northeast flank of the Cincinnati Arch, just within 
the Michigan Basin, the bedrock surface in Allen County is one of physio- 
graphic transition. The dolomite, limestone, and shale bedrock of Silurian 
to Mississippian age dips very slightly to the north and east. To the north 
the average bedrock elevation becomes less where valleys are cut into the 
softer shales. A carbonate rock plateau occupies the south half of the 
county, and a persistent escarpment separates it from the lowlands in 
the northern two tiers of townships (Fig. 2) (2). Glaciers from the Erie 
basin entered Indiana by riding obliquely up the slope of this escarpment.

compiled from more than 1,000 well, boring, and seismic records. 



All bedrock valleys in Allen County are tributary to the Teays Valley, 
about 50 miles to the southwest (2). The headwaters of the Valley F-C 
(Fig. 2), which are much steeper than those of Valley E-A, perhaps were 
deepened by proglacial waters of one of the pre-Wisconsinan ice advances 
that undoubtedly covered the area. 



Glacial Stratigraphy 

Two major drift sequences are present in the Fort Wayne area (Fig. 
3). A dense sand is commonly present at the base of the lower sequence, 
and its distribution appears to be partly controlled by topography on the 
bedrock surface, the thicker deposits commonly occupying lows. The lower 
drift sequence is composed of loam-textured glacial tills (C and D, Fig. 
3), having in places abundant interstratified sand, silt, and flowtill-type 
deposits, particularly near the top of the unit, and a persistent sand at 
about mid-depth. The tills typically contain 35 to 45% sand and 15 to 20% 
clay (grain-size analysis by American Association of State Highway 
Officials Designation T-88; Wentworth size grades). They are overconsoli- 
dated and are hard in the engineering sense of the word, having 
unconfined compressive strengths far in excess of 4 tons/ft 2 . Moisture 
contents are typically well below 10% and, correspondingly, dry densities 
commonly exceed 140 lb/ft 3 . The top of the lower till sequence rises from 
an elevation of about 735 feet in the axis of the Maumee Lake basin 
in easternmost Allen County to an elevation of more than 800 feet be- 
neath the moraines in western Allen County. Between the upper and

lower till sequences there is usually a dense fine silty sand, which helps 
separate the drift sequences in water well and engineering* boring 
records throughout the county. 



Geography and Geology 199 

The upper drift sequence is the series of clayey tills of the Erie Lobe 
(Fig. 3, A and B) that make up the concentric moraines of northeastern 
Indiana and northern Ohio. The upper tills are silty clay-loam to clay- 
loam textured, containing roughly 10% sand and 40 to 50% clay. They 
are stiff to very stiff in the engineering sense, having unconfined com- 
pressive strengths of 2 to 4 tons /ft 2 . Their moisture content is typically 
between 15 and 20% with dry densities ranging from 115 to 125 lb/ft 3 . 

A. M. Gooding ("Characteristics of late Wisconsinan tills in eastern 
Indiana," in preparation) gives evidence for the glacial retreat and subse- 
quent readvance of ice to the Wabash Moraine on the basis of a marked 
increase in clay content of surface tills within the Wabash Moraine. 
Although we have not as yet confirmed this in vertical section, numerous 
engineering boring and water well records and some measured sections 
indicate a distinct break marked by sand, gravel, or laminated clays with- 
in the upper till, which may represent the interval described by 
Gooding. 

The sequential relationship is quite straightforward in most places, 
but in the Fort Wayne Outlet and the Wabash-Erie Channel areas, as 
discussed below, the lower drift sequence generally becomes much more 
complex and the basal sand, the intermediate sand of the lower sequence, 
and the intersequence sand in places increase greatly in thickness. 

There is no evidence of any weathering interval between or within 
the till sequences, and thus we assume that both sequences record Wiscon- 
sinan glaciation. We believe that the lower sequence belongs to the 
Trafalgar Formation and the upper sequence to the Lagro Formation of 
Wayne (11). Wayne's plate 3 depicts a superposition of tills similar to 
that found in Allen County. Similar tills have also been described by 
Forsyth (5) near Defiance, Ohio. 

The stratigraphically lowest and possibly the oldest unconsolidated 
materials yet examined in Allen County are exposed in the May Stone 
and Sand Company Ardmore Road quarry (NE*4, Sec. 29, T30N, R12E). 
This unit (Fig 3, Unit 1) consists of about 7 feet of medium to fine loamy 
sand to cobbly gravel, which, when moist, is dark gray, olive gray, and 
olive (5Y hue). Distinguishing characteristics of these lowest gravels are 
their high content of pebbles of angular chert and of igneous and meta- 
morphic rocks, low content of shale, and lack of any carbonate except in 
a basal rubble layer. Clay mineral analyses show a significantly greater 
amount of mixed layered material than is present in samples of the area's 
oldest tills. The deposit rests upon Devonian limestone, possibly within 
a small bedrock valley, and is overlain by a generally clayey but variably 
textured till (correlation uncertain). It has the appearance of a weathered, 
reworked cherty lag deposit on an old erosion surface, but igneous and 
metamorphic pebbles indicate a previous or contemporaneous glaciation. 

The Classic Glacial Lake Maumee Sequence 

It has been supposed since 1915 that a lake level at about 800 feet 
was formed in the upper Maumee basin soon after the ice front re- 
treated from the Fort Wayne Moraine (9). This lake was succeeded by 



200 



Indiana Academy of Science 



another lake at 760 feet, after which the water rose again to 780 feet (790 
feet according to some sources). The Maumee stages of the pro-Erie Lobe 
lakes ended once lower outlets were free to discharge into the Saginaw 
Bay area and into the Grand River valley. 

For the sake of argument we will assume that three lakes existed 
at roughly these elevations. However, examination of 7% -minute topo- 
graphic maps not available to earlier workers shows that gross miscor- 
relations of beaches were made and that many of the supposed beaches 
are probably near-shore features other than beaches. Thus, we feel that 
the nature and origin of these features and their correlation and sequential 
order should be restudied. 

Knowledge of the basic glacial stratigraphy and of this classic lake 
sequence now provides the basis for a discussion of the morphology, 
stratigraphy, and developmental history of the outlets of the Maumee 
glacial lakes. 

Morphologic and Stratigraphic Relationships in the Wabash-Erie 
Channel and the Fort Wayne Outlet 
Terminology 

The entire valley through which glacial Lake Maumee drained, 
extending from just east of Fort Wayne to the Wabash Valley below 
Huntington, was called the Wabash-Erie Channel by Dryer (3). Leverett 
(8) preferred the term Fort Wayne Outlet for the same channel. Because

of their different although related origins we find it desirable to 
distinguish the mile-wide trough below Fort Wayne from that part of 
the valley that was cut through the Fort Wayne Moraine in Fort Wayne 
(Fig. 1). Therefore, we will use Dryer's term Wabash-Erie Channel for 
that single broad valley that is southwest of the city of Fort Wayne and 
that extends to Huntington. The head of this valley is the area of merging 
drainageways in the west half of T30N, R12E (Fig. 4). We will restrict 
the term Fort Wayne Outlet to that narrow valley extending from Sec. 
4, T30N, R13E, the western point of the Maumee lake basin, westward 
through Fort Wayne to the point where the St. Mary's River turns east 
in Sec. 2, T30N, R12E to join the St. Joseph River (Fig. 5). 

Morphology of the Outlet and Channel Floors 

The general course of the channel between Fort Wayne and Hunt- 
ington is of particular interest because of the possible indirect effect of 
bedrock topography upon the east-west segments (compare Valley D, 
Fig. 2, with Wabash-Erie Channel, Fig. 1) and because of the obvious 
effect of ice-controlled drainage upon the northeast-southwest segments 
of its course. As noted by Dryer (3), west of the outlet through the Fort 
Wayne Moraine "the channel turns to the southwest in a line which is 
a direct continuation of the valley of the St. Joseph River." Similarly, 
the valley also turns abruptly southwestward near the west Allen County 
line just west of where it bisects the Wabash Moraine and joins the contin- 
uation of Aboite Creek, which parallels the distal margin of the north 



■M.i:>

limb of the moraine. The St. Joseph and Aboite Creek drainageways, 
like the nearby Mississinewa, Salamonie, upper Wabash, and St. Mary's 
Rivers, clearly have ice-marginal or otherwise ice-controlled trends. 

Dryer (3) stated that "the present level of its bottom [the Wabash- 
Erie Channel] rises from 737 feet at the mouth of the St. Joseph to 756 
feet at the summit 4 miles west, then falls to 744 feet at the margin of 
the Niagara outcrop, and to 699 feet at its junction with the Wabash/' 
although Dryer recognized that those elevations did not record the scour 
depth of glacial lake outflow. He recorded about 4 feet of peat overlying 
blue clay underlying the Wabash-Erie Channel and 40 feet of silt over 
limestone at the outlet summit (discussed further below). Leverett (8), 
however, recorded the bed of the outlet in Fort Wayne as 755 feet (mis- 
quoted as 757 feet by Hough (7)) and noted that "parts of the bed are 
strewn with boulders and cobblestones, . . . indicating an old scourway. 
The northwest part of the city . . . stands on such a stony part of the bed." 
Leverett apparently considered the present floor at Fort Wayne to be the 
original scour depth, although he did recognize that below Fort Wayne 
"the bed is occupied by an extensive growth of peaty material, beneath 
which there is fine sand" and thus "had apparently been scoured out 
somewhat below its present level during the most vigorous stage of the 
excavation and was then filled in as the strength of the flow declined." 
The surface elevation in the northwest part of Fort Wayne, southwest of 
the confluence of the St. Joseph and St. Mary's Rivers, is, indeed, be- 
tween 755 and 760 feet (Figs. 1 and 4). The configuration of the con- 
tours, of course, has been greatly affected by the building of the city, 
and for that reason they have not been shown on parts of Figures 4 and 
5. 

Of special interest, however, is the form of the outlet channel east 
of the city, where it is cut through the moraine. The outlet valley is for 
the most part occupied by the Maumee River floodplain at an elevation 
slightly greater than 740 feet, but in Sees. 3, 4, and 5, T30N, R13E, ter-

races at about 750 feet (along line of Cross Section J J', Fig. 5) record the 
former scoured lake floor where it merges with the outlet. 

The form of the westernmost lake bottom (along line of Cross Section 
KK', Figs. 5 and 6) clearly shows the constriction but also the continua- 
tion of the 750-foot contours into the outlet valley. It is clear from this 
geomorphic evidence that the original scoured depth in the outlet and 
channel downstream must have been even lower than 750 feet. In fact, 
this is exactly what the channel stratigraphy shows us.

radio-carbon dated) fill a scoured trough in the north half of the east- 
west part of the Wabash-Erie Channel (Fig. 7, Cross Section FF', as 
representative of Cross Sections CC through H in Fig. 4). Even across 
the limestone sill at Huntington where Leverett (8) stated the elevation 
of the channel floor, and presumably the limestone surface, to be 744 feet, 
more than 7 feet of fine-grained fill is present over the limestone, which 
is at an elevation of about 735 feet in the center of the channel (along 
Cross Section A A', Fig. 4). Maximum elevations of the floors of the Fort 
Wayne Outlet and the Wabash-Erie Channel before the postlake infilling 
of the channel are given in the captions for Figures 4 and 5. It is clear 
that a significant buried trough, about the width of the valley of the Fort 
Wayne Outlet, occupies part of the larger Wabash-Erie Channel. The floor 
elevation of the buried trough, not the surface elevation, records the depth 
to which glacial Lake Maumee scoured. The buried channel floor appears 
to have broadly spaced highs and lows, whose origins are difficult to 
interpret. However, filling by at least the uppermost fine-grained unit 
must postdate the Lake Maumee discharge, and we interpret this to mean 
that the St. Marys and St. Joseph Rivers continued to flow sluggishly 
westward down the channel prior to the development of the Maumee River.

The geology of the channel area is particularly complex. Inter- 
sequence sand and silt or lower sequence sand is present beneath the 
latest channel filling in many sections across the channel, the outlet, and 
the westernmost lake bottom (Fig. 7 and as along Cross Sections J J' and 



204 Indiana Academy of Science 

LL', Fig. 5). Because of this, it is almost impossible to assign position 
and age to many such deposits that occur immediately below the latest 
fine-grained fill. Often, only engineering data can give any clue as to 
whether sediments are exhumed or postglacial. Furthermore, there are 
several very deep holes in the channel filled with as much as 25 feet of 
soft (not overconsolidated) sediments to well below even the elevation 
of the bedrock sill at Huntington (see captions, Figs. 4 and 5). 

Stratigraphic Evidence Bearing upon the Early Development of the 
Channel 

Preliminary study of subsurface data suggests that the route of the 
present channel in and just west of Fort Wayne is roughly parallel to the 
route of drainage associated with lower sequence ice. Furthermore, two 
upper sequence tills, possibly representing the advance of the Erie Lobe 
to the Wabash Moraine and an earlier Erie Lobe advance, are separated 
in one major exposure on the south wall of the present channel (Midwest 
Aggregates quarry, Sec. 36, T30N, RUE) by a thick gravel that contains 
armored till balls derived from the lower till. This outwash may have been 
concentrated, before formation of the Wabash Moraine, along the present 
trend of the Wabash-Erie Channel, just as earlier meltwaters had been 
concentrated there. 

During later development of the channel, high level outwash was 
deposited west of the confluence of the St. Joseph and St. Mary's valleys 
in continuation of the terraces in those valleys. Outwash as much as 25 
feet thick is present as high as 785 feet in the west half of T30N, R12E 
(Figs. 1 and 4). Thus, a precursor of the present Wabash-Erie Channel 
was also in existence while the Fort Wayne Moraine was forming and 
discharging outwash through the St. Joseph and St. Marys valleys. 

The lows in the channel floor that are filled with soft sediment in 
some way relate to the overall development of the channel. Were they 
cut by waters under considerable head flowing off or through ice? Do 
they represent plunge pools that consecutively developed as the channel 
lengthened? Or is there another explanation? We do not know. 

But as a generalization, we can say that the Wabash-Erie Channel 
had a long, perhaps in part repetitive history of drainage and that most 
of the route as we see it today was an already established drainageway 
before the Fort Wayne Moraine and thus also before the Maumee glacial 
lakes came into existence. As noted above, the course of the main east- 
west segment of the channel may have been indirectly bedrock controlled, 
and the northeast-southwest courses were determined by ice. 

Six Mile Creek Channel 
Morphology 

The only other incised breach in the Fort Wayne Moraine, the Trier 
Ditch, or the Six Mile Creek Channel as it was called by Dryer (Figs. 1 
and 5) (3), connects the St. Marys River at 750 feet elevation with the 
Maumee River 8% miles away at an elevation of 740 feet (Figs. 1 and 5). 
In the northern one-third of its length the channel broadens considerably 
and the 780-foot scarp swings into the embayment. The course of this

channel may have been indirectly determined by a minor bedrock valley 
Fig. 2 E), which was tributary to one of the major north-flowing pre- 
glacial streams. 

Glacial and Postglacial Stratigraphy 

As elsewhere in the Fort Wayne Moraine, the stratigraphy is rela- 
tively simple and is described by the basic sequence shown in Figure 3. 
In the southern part of the channel a thick basal sand is overlain by hard 
sandy till of the lower sequence (Cross Section 00', Fig. 8, as representa- 
tive of Sections NN' through RR'). This in turn is overlain by a thin dense 
fine sand or silt of the intersequence unit. The upper clayey till sequence 
lies above. All glacial stratigraphic units, as shown on Cross Section MM' 
(Fig. 9), drop in elevation northward as they approach the lacustrine 
plain and the axis of the Erie Lobe. The upper part of the lower sequence 
here and near the main Fort Wayne Outlet becomes much more varied 
where it is topographically low, containing abundant intercalated sand 
and silt. Lacustrine and fluvial materials associated with glacial lakes

and recent alluviation rest on both upper and lower sequence units along 
the channel, depending upon the depth of erosion. 

Although there may have been a bedrock-determined initial sag, there 
is no indication that the Six Mile Creek Channel was active prior to 
deposition of the upper clayey till sequence. It appears that the contact 
of the upper and lower sequences may be lower there than it is a few miles 
to either side, but the data are insufficient to tell whether this indicates 
a valley or a local, closed low. The scoured floor of the present channel 
was cut in upper sequence clayey till at an elevation of 755 feet and, as 
would be expected, does seem to drop in elevation at both ends. The slope 
to the St. Mary's is very short and can be attributed to the more recent 
drainage. The slope to the north begins nearly half way along the length 
of the channel, is very gentle, parallels the boundary between the lower 
sequence till and the basal sand, and becomes difficult to trace as the 
stratigraphy becomes complex near the lake border. Leverett (8) pointed 
out that current bedding in gravels exposed southwest of New Haven 
shows a southward transport, which he attributed to drainage from glacial 
Lake Maumee. Cross beds could, of course, be related to storm deposits 
or longshore drift. Furthermore, it is obvious (Cross Section MM', Fig. 
9) that no coarse sediment is found in the base of the channel in its 
southern half and that there is no appreciable buildup of such material 
opposite its south end. Thus, there is no clearcut reflection in morphology 
or general stratigraphy of the lake drainage that must have passed south- 
ward in the Six Mile Creek Channel. 

As suggested by Dryer (3), the St. Mary's River used the channel 
as a flood stage outlet after lake levels had dropped. As recently as 1913, 
a flood of water 5 feet deep flowed through it. Leverett and Taylor (9) 
made reference to this event, and Dryer suggested that it was a frequent 
occurrence before the advent of modern drainage controls. 

Dryer (3) defined a large sandy area in and just east of New Haven 
as the delta of the St. Mary's-Six Mile Creek Channel. However, the topo- 
graphically prominent sand at the east end of the supposed delta appears 
to us to be dunal rather than deltaic, the dune sands lying upon coarse 
sands on the lake floor. The broadest expanse of the so-called "delta" is 
found in the city of New Haven where the elevation is about 760 feet, but 
most of the town is underlain by hard loam till. 

The Six Mile Creek gap, like the Fort Wayne Outlet, was very likely 
an original low in the Fort Wayne Moraine. When the ice of the Erie Lobe 
began to recede, there were surely isolated small lakes ponded in front 
of it which had their own outlets. Six Mile Creek, which is now of a magni- 
tude equal to that of the channel of the Imlay Outlet, may have been one 
of these. Although a large quantity of meltwater may have been spilled 
through Six Mile Creek Channel after integration of the ice marginal lakes 
into Lake Maumee, the prevailing currents and sediment transport from 
the lake bed were through the larger Fort Wayne Outlet. After the lake 
was emptied and present drainage patterns established, the Six Mile Creek 
Channel acted as a floodwater route for the St. Marys River. 



Geography and Geology 207 

Evidences for the Lake Sequence 

Since Leverett's (8) first description in 1902 of the high stand of 
glacial Lake Maumee, it has been assumed that that lake drained primarily 
through the Fort Wayne Outlet and the Six Mile Creek Channel. Although 
Taylor (9, 12) had traced the uplifted continuation of the highest beach 
to a point 6 miles north of Imlay, Michigan, well north along the west 
wall of the present channel at Imlay, neither author, for some reason, 
concluded that the high lake drained at Imlay. It has been always recog- 
nized that the intermediate lake level drained through the Imlay Outlet, 
but Hough (7) pointed out that that level, too, must have drained 
through the Fort Wayne Outlet. Leverett (8) originally accounted for 
the change in level from 800 feet to 780 feet by the opening of the 
Imlay Outlet. If the high lake drained at Imlay, however, the opening of 
the Imlay Outlet alone (at least to the extent of the channel presently 
visible) could not explain the lowering of the lake to the 780-foot level. 

The "third beach" at 760 feet was recognized in 1908 by Leverett 
(11) and was placed last in the sequence, although Leverett suggested 
the possibility that the low level might actually be intermediate in age, 
based upon its "rather washed-down appearance." Leverett further stated 
that the third Maumee beach "appears to have been barely high enough 
to have opened into the Imlay Outlet if its northward rise is as rapid as 
that of the first and second beaches." Taylor (9), however, made no men- 
tion of this observation, and assumed that the floor of the Imlay Outlet 
visible today, like the floor of the Fort Wayne Outlet, was too high to have 
drained the low-level lake. 

We believe that the overriding reason for Taylor's (9) placing the 
760-foot lake level between the two higher levels in the lake sequence was 
not the washed look of the 760-foot beaches, rather it was that the 
presumed lack of an outlet for the lowest lake necessitated the 
postulated burial of the lake's outlet by a subsequent glacial advance that 
also raised the level of the lake. Taylor (9) felt that a "readvance of the 
ice did not [completely] close the [wider and deeper 760-foot] 
outlet [at Imlay] but pushed it [westward] up the slope to the 
place where the Imlay outlet channel is now found." The head of the 
Imlay channel visible today was thought to have drained only the last 
level, the 780-foot lake. 

However, we have shown that the scoured floors of the Fort Wayne 
Outlet, the Wabash-Erie Channel, and the Six Mile Creek Channel are 
deeper than previously assumed. At least 10 feet of water from a 760- 
foot lake could have passed through the Fort Wayne Outlet, and concur- 
rently 5 feet of water could have passed through the Six Mile Creek 
Channel. Furthermore, the important limiting elevation of the limestone 
sill at Huntington is nearly 10 feet less than indicated by Leverett, and 
thus discharge gradients of all lakes were considerably more than 
previously assumed. Preliminary study of modern IVz' topographic maps 
seems to indicate that the two high beaches can indeed be traced into the 
Imlay channel and that taking into consideration about 50 feet of post- 



208 Indiana Academy of Science 

glacial uplift, the 760-foot lake might also have barely discharged through 
the channel, just as Leverett (11) suggested. 

The subdued or washed look of the 760-foot beaches has never been 
quantitatively documented in the literature. Many of the classic 760-foot 
beaches are far above that elevation, others can easily be explained as 
nonbeach features, and any truly subdued beach certainly can be explained 
in other ways than by the washing action of a higher lake. Therefore, 
we feel that there is no evidence for other than the simplest sequence of 
the classic Maumee Lake Levels, 800 feet, 780 feet, 760 feet. 

Cause of Change in Level 

An 800-foot lake level would have been controlled by the initial 
configuration of the surface of the Fort Wayne Moraine. Assuming a 
constant discharge rate, it is possible that the opening of a discharge route 
at Imlay in addition to the Fort Wayne and Six Mile Creek outlets could 
have balanced the lake level at a lower elevation, as Leverett (8) origi- 
nally suggested. But backcutting in the Fort Wayne Outlet eventually 
would have cut through the moraine, perhaps in a "stoping" process of 
headward advance of a rapids or chute similar to that postulated for the 
outlet of glacial Lake Chicago by W. C. Alden (1) and modified by J. W. 
Goldthwait (6) in the early 1900's. 

We suggest the possibility that a significant stratigraphic sill, the 
top of the lower hard till, could have temporarily slowed downcutting at 
Fort Wayne, perhaps causing a stabilization of the lake at the intermedi- 
ate level. The Fort Wayne Outlet is cut into intrasequence sand and 
apparently into the lower hard till, which is encountered at 750 feet in 
borings in Fort Wayne just south of the outlet, and up to 780 feet just 
northwest of the city (Fig. 7). (The Six Mile Creek Channel is cut entire- 
ly in the upper clayey till.) The lowest lake level could have been initiated 
once erosional equilibrium was attained in the outlet and channel, or the 
lake could have been stabilized by a balance between glacial melting and 
lake discharge, perhaps due to partial opening of the drainage route that 
eventually lowered water to the glacial lake Arkona levels.

Engineering Soils Mapping in Indiana by Computer from Remote 
Sensing Data 1

Abstract 

Multispectral imagery of the surface terrain may be obtained from airborne scanning 
devices that measure reflectance in the visible through infrared portion of the electromag- 
netic spectrum. At the Laboratory for Applications of Remote Sensing (LARS), Purdue 
University, multispectral imagery is analyzed using a high-speed digital computer. The 
final result is a detailed map or classification of the surface material. 

Pattern recognition (classification) is accomplished by separating materials accord- 
ing to their spectral response statistics in a known area and then applying these 
criteria to unknown areas. As an example of the LARS mapping technique, a detailed 
analysis of a soils area in north-central Indiana is presented. 

In this study the correct classification of sandy floodplain soils versus till plain 
soils was obtained for 98 + % of the ground area elements (remote sensing units) 
for the training fields. Similarly a 76 + % correct discrimination between the 
two materials was made for the test fields in the flightline. This degree of accuracy indi- 
cates that the analysis of these data using the LARS techniques was successful in 
differentiating the materials sufficiently well to be of considerable use in reconnaissance 
surveys. 

Introduction 

Aerial photography has been used for several decades in reconnais- 
sance mapping of soil, rock, vegetation and man-made features in a variety 
of scientific specialties, including geology, geography, agronomy, forestry, 
hydrology, civil engineering and a number of others. With the development 
of improved instrumentation systems for measuring electromagnetic radi- 
ation of the terrain and with the advent of high-speed computers, it is 
now possible to obtain more precise data which can be analyzed in great 
detail by digital computers. 

Remote sensing involves the identification and classification of 
physical objects through analysis of data obtained from sensing devices 
which do not come in direct contact with those objects. In most cases the 
instruments measure radiation intensities from selected portions of the 
electromagnetic spectrum. For remote sensing studies that incorporate 
analysis by computer, the data-gathering phase is followed by some data 
reduction and reformatting which expedites subsequent data processing. 
The final phase, analysis, involves classification of the target materials 
through the use of pattern recognition techniques. 

This paper presents a discussion of remote sensing of soil and rock 
materials with specific emphasis on the techniques developed at the 
Laboratory for Applications of Remote Sensing, Purdue University.

Methods: LARS Automatic Classification Technique 

Perhaps the first question to answer is why use an automatic 
classification system at all? Why not rely on the current method of 
mapping soil and rock for geological and other purposes. An obvious 
answer is that computers are faster and more accurate. Computer use 
does not remove the scientist from the operation; it makes him more 
important. As before, accurate field work is necessary; however, the same 
amount of field effort can now be used to map a larger area. Reliable data 
are needed to train the computer for proper classification but this detail 
is not required for the entire mapping area. 

Currently, multispectral imagery of the terrain is obtained for LARS 
by the Institute of Science and Technology, University of Michigan, using 
a multispectral optical-mechanical scanner mounted on their DC-3 aircraft. 
As the plane proceeds along the flight path, the energy radiated by a 
specific ground resolution element passes through the scanner optics, is 
divided according to its spectral wavelength, and is directed to the 
appropriate detector. The output of all such detectors is simultaneously 
recorded by a multiband recorder. The transverse motion provided by 
the rotating mirror and the forward motion of the aircraft cause a contin- 
uous signal to be recorded for each spectral band of the scanner output. 
The information is stored in analog form by the data recording system. 

The multispectral bands recorded on the aircraft storage tapes vary 
according to the needs of the researcher. In this study, 12 channels of 
data were obtained from the visible and reflective infrared portion of the 
spectrum, between 0.4 and 2.6 micrometers 1 (^m). 

Following the multispectral remote sensing flights, the aircraft 
scanner analog data tapes are forwarded to LARS for conversion to digital 
form. Each analog scan is sampled, normally at a sampling rate which 
yields 220 data points for an 80° field of view across the flightline. For 
later reference, each digitized data point (remote sensing unit or RSU) 
is assigned a unique address in a two-dimensional coordinate system based 
on scan line numbers ("line numbers") and samples within the line 
("column numbers"). 

Typically the first step in the analysis is to obtain gray scale print- 
outs of the data for several channels. Gray scale printouts are digital 
displays of the spectral response of the terrain but limited to one band 
or channel of the scanner data per display. They resemble low-resolution 
photographs. Alpha-numeric symbols (letters of the alphabet, typing 
symbols and single digit numbers) are assigned to the radiance levels so 
that high-intensity or light areas receive symbols which cover a low 
percentage of the paper (Example — ), and dark areas receive symbols 
with a high percentage of cover (Example MMM). Because the data are 
not equally distributed between the highest and lowest radiance values, 
the symbols are not simply assigned so that each represents an equal range 
of radiance. Instead, to achieve a maximum contrast display, the data 



'One micrometer (^m) = 10 -6 meters. 



212 Indiana Academy of Science 

are first histogrammed and the symbols are assigned so that each will 
occur with approximately the same frequency. 

Areas of known materials are located on the gray scale printouts by 
the researcher and their addresses are recorded. This information, 
referred to as "ground truth," is used to train the computer to recognize 
similar kinds of material. In agricultural studies, this may consist of fields 
containing corn, wheat, oats, soybeans, etc.; in forestry studies — conifers 
and deciduous trees or individual tree species; in geology and highway 
engineering — specific bedrock and soil types. While some of the ground 
truth areas are used to train the computer to recognize the classes of 
interest, the remaining areas are reserved for testing the accuracy of the 
computer classification after it is completed. Addresses of training areas 
are provided to the computer on punched cards; these addresses are 
boundary corners indicated by column and line number, and the fields 
are limited to rectangular shapes (commonly referred to as "fields"). 

After January 1, 1971, an alternative to using gray scale printouts 
for field selection became available at LARS. This tool, known as the 
digital display unit, provides a television-like image of the scanner data 
with each digital value represented by a different brightness level. This 
yields an image on the television screen having greater detail than is 
possible with gray scale symbols on computer paper. Images for each 
channel can be displayed, and fields of interest can be outlined on the 
screen using a light pen with their addresses automatically punched on 
cards. 

Another method for obtaining training field sites is sometimes used 
in conjunction with the above procedure of manually selecting these sites. 
Accomplished by using the LARS non-specified classifier routine 
(NSCLAS), this relatively new technique divides the scanner data into 
groups or clusters based on similarity of spectral response within clusters. 
Typically 4 to 6 channels of imagery are analyzed simultaneously and the 
program is requested to obtain 10 clusters. A map of the results is printed 
for each area analyzed in this way and the researcher can observe the 
patterns of spectrally differentiable material occurring in the data. The 
training fields may then be selected from these maps. The resulting 
clusters may not in fact be spectrally distinct, but the researcher must 
decide this to his own satisfaction based on separability information for 
the clusters which is printed by the program. He then has the option of 
repeating the analysis using a different number of clusters to increase 
their separability. An important point is that this method of selecting 
training fields takes into detailed account the multispectral response data 
as well as the ground truth information. 

In the clustering approach, the actual differences in spectral response 
are displayed, but a major problem exists in determining what each of 
the clusters represents. Some may be vegetation types, some water bodies, 
man-made features or tonal aspects of bare soil and rock. Aerial photog- 
raphy is helpful in affixing names to the patterns observed. Despite this 
difficulty, clustering is a powerful tool in obtaining workable training 
fields. 



Geography and Geology 213 

The next step in the analysis is to obtain histograms of each class 
of material identified in the training fields. An example of classes for 
a geologic study area might be alluvium, limestone soil, shale soil, trees, 
mixed crops, and water. The histograms for each class show the distribu- 
tion of reflectance intensity for each spectral channel. 

Unimodal or single-peaked distributions in the histograms for a class 
suggest that the proposed class is spectrally an individual group. Bimodal 
or trimodal distributions must be subdivided manually into unimodal 
classes by the researcher; histograms for individual fields can be obtained 
to help in locating the multimodal contribution within a class. 

The next operation involves the application of a divergence 
(statistical separability) analysis (known as $DIVERG) to determine 
the best channels to use for classification. Only the best four to six 
channels are used for classification to save computer time; in general, 
the accuracy is not meaningfully increased when more channels are added. 
In addition to indicating the preferred channels, the divergence analysis 
indicates the separability of the designated classes. If separability between 
significant materials is poor, some of the preceding steps are repeated 
in an attempt to improve this separability and hence classification 
accuracy. 

Next, training field statistics are used to classify the designated 
portion of the flightline. The computer classifies each data point (RSU) 
based on the maximum likelihood criterion. On request, the computer 
calculates how accurately it classified the areas used for training by 
comparing the classification of each point in the training fields with the 
initial ground truth designation. A high level of agreement means there 
is minimal confusion within the training field statistics for the various 
materials and that the classes are being separated properly. 

The final steps are to print out a computer classification for the whole 
area and to determine how well the test fields were classified. The test 
fields are those areas of known material from ground truth studies that 
were not previously used for training purposes. If test fields and train- 
ing fields show a high degree of accuracy, and the test fields are repre- 
sentative of the entire area, the classification is a good one. If the accuracy 
is low, some reworking of the classes should be done. The researcher may 
also have to conclude that the classes involved are not spectrally separable. 

Results: Tippecanoe County, Indiana, Study Area 

To illustrate the automatic classification technique for engineering 
soils mapping, a flightline in Tippecanoe County, Indiana, was selected 
for study. The test site known as Tippecanoe County Flightline 23 is a 
north-south line running approximately through the center of the county, 
including a central strip through the Lafayette-West Lafayette metro- 
politan area along the Wabash River (Fig. 1). 

Scanner data were obtained for Flightline 23 during various seasons 
of the year in 1969 and 1970 for the on-going LARS program of study 
of the midwest corn belt area. Seasonal changes of soil patterns and crop

cover were observed by these periodic flights over the established 
flightline. In the current study, the scanner flight dated May 6, 1970, was 
selected for analysis. In general, spring flights are best for soil classifica- 
tion studies as the maximum percentage of bare soil is exposed at this 
time of year. 

Analysis was limited to the northern third of the flightline which 
contains examples of the soil materials of greatest interest in the study. 
The northern 5 miles of the flightline cover a portion of the Tipton Till 
Plain. South of this segment is a 2-mile section which runs across the 
Wabash River floodplain. These two sections comprise contrasting parent 
materials and form the basis for the soils study of the 7-mile area. Flown 
at an elevation of 3,000 feet, the flightline has a width of about 5,000 
feet. 

The initial step in the analysis technique was to compare a gray scale 
printout of the flightline to black and white photography taken at the 
time of flight. The Wabash River was outlined, as were the floodplain

and till plain areas and several significant man-made features: the By- 
Pass 52 bridge and Interstate 65, which was under construction at the 
time of flight. 

To determine the material types present in the study area, 13 east- 
west strips of data were taken at various points of interest along the 
flightline. An NSCLAS was run on these combined transverse strips which 
collectively comprised nearly the maximum number of data points that 
the routine can handle. 

In the 13 clustered strips, vegetation, water, man-made features and 
bare soil were identified with the aid of the aerial photography. 
Rectangular fields were selected in the bare soil areas and a second 
NSCLAS was run on these combined areas using ten clusters for the 
analysis. This yielded a numerous collection of rectangular fields with 
soil patterns designated in each. 

By selecting those fields (or portions of fields) which had predomi- 
nantly one pattern, a collection of bare soil fields, each of essentially one 
soil type, was assembled. Two distinct groups were maintained, however: 
those fields from the floodplain area and those from the till plain. 

Next, statistics were obtained for each field and the histograms 
examined to insure that each was unimodal. Three divergence analyses 
($DIVERG) were made on the fields to determine how to combine them 
into separable classes. Two runs were required initially because the pro- 
grams accept a maximum of 30 fields in the divergence analysis and the 
50 fields were divided into two groups to accomplish this. Fields deemed 
similar by the divergence analysis were combined, whereas, others were 
left by themselves and a few confusing fields discarded. After this was 
achieved for the two divergence runs, the remaining groups (numbering 
less than 30) were collected in the final divergence analysis and the 
combining technique repeated. The net effect is that 18 classes remained 
after this compilation, 8 from the floodplain area and 10 from the till 
plain. 

Several classifications were made of the 7-mile segment using the 
training statistics from these classes. Adjustments were made in succes- 
sive classifications to improve the training field performance. In the final 
classification this performance was sandy floodplain 99.1%, and till plain 
98.5%. These values are somewhat misleading as a considerable number 
of floodplain symbols were scattered within the till area although the till 
symbols are rather minimal in the floodplain area. 

To obtain a more meaningful indication of the classification's 
accuracy, a large number of bare soil fields were selected as test fields. 
In the sandy floodplain, 28 test fields containing a total of approximately 
1,900 RSU's and 59 test fields in the till plain (approximately 8,700 
RSU's) were included. Test results showed 92.7% accuracy for the sandy 
floodplain and 76.8% accuracy for the till plain with an overall accuracy 
of 76.8%.

Because of limitations on the size of figures and their number in this 
paper, the computer printout, which is quite large and loses much detail 
in photo reduction, is not included here. 

An intriguing situation was noted during the classification revisions. 
The till plain areas most often confused with floodplain soils were in recent 
road cuts where reflectance of the till was the greatest. This was observed 
near the By-Pass 52 bridge cut on the west side of the Wabash River and 
for borrow and fill areas along Interstate 65. 

An interesting substudy was made on the flightline as a final effort. 
Interstate 65 runs diagonally NW-SE across the flightline. Experience 
at LARS has indicated that straight line, man-made features not oriented 
essentially parallel or perpendicular to the flightline are difficult to map 
in detail. Diagonal features of this sort run both away from the center 
of the flightline yielding changes in viewing angle from the aircraft, and 
up or down the flightline simultaneously. Also, as remote sensing units 
measured on the ground are square, the units along the pavement 
boundary have an averaged value of reflectance for both pavement and 
soil. If training samples are taken from this boundary portion, erroneous 
pavement symbols will appear in soil areas in other locations of the classi- 
fication. 

To master this problem, we clustered (NSCLAS) rectangular areas 
across the highway from the southeastern edge to the northwestern edge 
of the flightline. Ten cluster groups were designated. The pavement, 
median strip and shoulders were outlined in the clustered map results. 
As might be expected, the same cluster group was not associated with 
the pavement in the center as at the edges of the flightline, but the 
contrast of pavement and soil was apparent at each location. To insure 
proper classification, pavement classes from the middle, quarter point and 
edge of the flightline would be included for accurate designation of the 
highway in an overall classification.

Abstract 

Indiana streams erode, transport, and deposit a variety of sediments. About 
10 years ago an inter-agency committee was formed to accelerate investigations of these 
sediments. This committee consists of representatives from federal and state agencies. 
Recent fluvial sediment studies on selected streams indicate a range in sediment yield of 
from 30 to 880 tons annually per square mile of drainage area. Studies of sediment 
deposited in selected reservoirs indicate that the area draining into these impondments 
is eroded at rates of from 3 to 22 acres annually. The reservoirs studied are losing 
storage capacities at the rate of from 0.1 to 2.9 percent annually. 

Water-transported sediments have been the subject of study in 
Indiana for many years. Observations of fluvial sediments — those in 
transit in flowing streams — date back at least to 1906. Early studies 
consisted of observations only and included no precise measurements, 
however (3). 

Imponded sediments — those relatively stationary in natural lakes and 
reservoirs — have been measured since about 1930. The first such recorded 
measurements were made on Winona Lake and Tippecanoe Lake, both 
natural lakes formed during the Pleistocene Epoch or ice age (3). 

Winona Lake is estimated to have decreased in depth from 127 feet 
to 79 feet from the time it was left by the glacier to 1930. In this period 
of time the surface area and volume of Winona Lake were reduced 37.4 
and 43.6%, respectively. During this period the maximum depth of Tippe- 
canoe Lake decreased from 164 feet to 123 feet, and the original surface 
area and volume were reduced 20.8 and 31.9%, respectively. 

Recent fluvial sediment studies have been carried out cooperatively 
by the Geological Survey of the United States Department of the Interior 
(USGS) and the Indiana Department of Natural Resources (IDNR). The 
first of these studies began in 1953 on the St. Mary's River near Ft. 
Wayne (1). The location of the suspended sediment sampling stations 
are shown in Figure 1, and Table 1 lists available data obtained from 
these studies. 

The fluival sediment studies show that each square mile contributes 
from 30 to 880 tons of sediment annually. The size of drainage area that 
contributes to the measurement sites varies greatly. The larger the drain- 
age area the smaller the proportion of transported sediment that reaches 
a measuring point. The fluvial sediment studies are of insufficient dura- 
tion, however, to provide more than a general estimate of the average 
annual sediment discharge for the streams.

About 10 years ago several interested agencies and organizations 
banded together to form a rather losely organized inter-agency committee 
to study erosion and sedimentation in Indiana. This committee proposed 
two distinct types of studies, comprehensive studies and limited studies.

The comprehensive studies were to interrelate many environmental 
factors related to erosion and sedimentation. Such disciplines as biology, 
geology, meterology, soil conservation, hydrology and sedimentology were 
to be involved in each watershed and lake study. The limited study was 
planned to include the measurement of sediment in a lake and a study 
of the erosion taking place in the area draining to the lake. 

Unfortunately, no comprehensive studies have been made because 
of lack of funds and personnel, but numerous limited studies have been 
undertaken. 

The inter-agency committee includes representatives of the U.S. 
Geological Survey, Indiana Department of Natural Resources, 
U. S. Army Corps of Engineers, the U. S. Department of Agriculture's 
Agricultural Research Service (ARS) and Soil Conservation Service 
(SCS), the Water Resource Research Centers at Indiana University 
and Purdue University and the Indiana Department of Natural Resources' 
Geological Survey (IGS). 

The major effort of the committee has been in arranging for and 
conducting reservoir sediment studies. To date studies have been made 
at 15 reservoirs in the state. Locations of these reservoirs are shown in 
Figure 1, and pertinent data obtained from these studies are given in 
Table 2. The procedures employed in these studies have been pre- 
viously reported (2). 

The results of the reservoir surveys indicate soil losses ranging from 
3 to 22 tons annually, and losses of original storage capacity of from less 
than 0.1 to 2.9% per year. As in the case of the suspended-sediment 
studies, data are insufficient to allow complete evaluation. 

Additional reservoir studies are being planned, and resurveys are 
anticipated. It is normal procedure to allow a 10-year period after con- 
struction of a reservoir before the first sediment survey. The Corps of 
Engineers has installed, or is in the process of installing sediment ranges 
on Lakes Huntington, Salamonie, and Mississinewa. Continuing studies 
are being made on Cataract, Mansfield and Monroe Lakes by the Corps. 
The IDNR has installed sediment ranges on Deems Lake in Clark County 
and on the Quick Creek Reservoir in Scott County. The SCS has recently 
completed a sediment survey on Lake Salinda, a water-supply reservoir 
for Salem, Indiana (Table 2). Sediment ranges have been installed by 
SCS on the Elk Creek fish and game reservoir in Washington County and 
on the French Lick Creek fish and game reservoir in Orange County. 

At the time of this writing, two Purdue University students, L. J. 
Lund and Manuel Poulet, are preparing a paper on some pedologic fea- 
tures of reservoir sedimentation. This study involves 14 Indiana and 
Illinois reservoirs and their drainage areas. 

The long-range plan of the committee calls for resurvey of most of 
the reservoirs after ten years of additional sedimentation, or more fre- 
quently if conditions warrant. Ideally, a survey should be made immedi- 
ately before and after a large sediment producing storm. Such storms 
usually occur at ten-year intervals.

Abstract 

Regional statewide gravity and magnetic surveys in Indiana reveal large areas of 
high and low intensities. The source of these variations are lithologic changes within the 
Precambrian basement. A generalized map of basement provinces, constructed from both 
gravity and magnetic data, identifies regions of basement lithologies as either dense or 
magnetic-rich rocks or combinations thereof. 

Analyses of intense, magnetic anomalies reveal the basement surface to vary from 
2,000 to 11,000 feet below sea level. Many of the anomalies appear to be concentrated 
along the Cincinnati Arch. Detailed studies of two regions suggest that the sources may 
be basaltic pipe-like intrusions into a granitic country rock. Lava flow structures may be 
associated with the individual pipes. 

Introduction 

Geophysical surveys today constitute an important and integral part 
of almost every modern effort at geologic exploration. For many years 
the petroleum industry has routinely utilized seismology, gravity and 
magnetic methods in the search for oil beneath both the land and sea. 
However, the cost of geophysical surveys in the past have limited their 
use to major companies. With advances in technology, the cost of such 
surveys is not necessarily prohibitive. This paper summarizes data that 
are applicable to the study of Precambrian basement in Indiana and 
emphasizes regional interpretation based on the most recent gravity and 
magnetic studies. 

Gravity Data 

The first extensive gravity survey in Indiana (Fig. 1A) was 
conducted by the Indiana Geological Survey during 1951 and 1952 (3). 
Control was based upon a grid density of approximately one station for 
each congressional township. Elevation and locations were determined 
from several sources including U. S. Coast and Geodetic and U. S. Geo- 
logical Survey bench marks, U. S. Geological Survey topographic maps, 
U. S. Engineering maps and Indiana State Highway Commission maps. 

Contours show equal values of Bouguer anomaly relative to an arbi- 
trary datum with an interval of 5 milligals. Bouguer corrections were 
based on an average density of 2.6 gm/cm 3 for the sedimentary rocks 
above sea level. In addition to the statewide gravity survey, the Indiana 
Geological Survey and the Department of Geology at Indiana University 
have conducted detailed surveys over selected anomalous regions in 
Hamilton, Pulaski, Newton, Randolph, Wayne and Fayette Counties. 
These data are available on file with the Department and the Survey.

magnetic intensity U). Contour interval 50 gammas relative to an arbitrary datum. 



Magnetic Data 

From 1949 to 1952, the United States Geological Survey, in coopera- 
tion with the Indiana Geological Survey, conducted a statewide aero- 
magnetic survey of Indiana. Ninety-two county maps were published on 
a scale of 1"=1 mile (1:63,360) with a contour interval of 10 gammas 
(0.0001 oersteds). In 1958, Henderson and Zietz compiled the county maps 
into a statewide map on a scale of 1"=8 miles (1:500,000) (Fig. 2). Con- 
tours represent equal values of the total magnetic intensity at an eleva- 
tion of approximately 1,000 feet above the surface. Contour interval is 50 
gammas relative to an arbitrary datum. 

Comparison of the aeromagnetic and gravity maps is difficult be- 
cause of the discrepancy in control between the two maps. The gravity 
map, based on few control points, emphasizes broad scale regional 
features; the aeromagnetic map with continuous north-south control at 
1-mile east-west flight line intervals shows great detail and thereby 
obscures broad scale features. 

In 1953, an average magnetic intensity map of the state was com- 
piled from the aeromagnetic data (4) (Fig. IB). Control was based on 
average values obtained for the mid-point of each township by computing 
the arithmetic average of the magnetic intensity at the corners, the mid- 
point of each side, and the center of each township. Average values were 
further reduced by removing a south to north earth dipole gradient of 
6.5 gammas per mile. Contour interval is 50 gammas relative to an arbi- 
trary datum. Station density and contour intervals for the average mag-

netic intensity map are comparable to the gravity map and allow 
comparative interpretations to be made. 

In recent years, the Indiana Geological Survey and Department of 
Geology at Indiana have conducted detailed magnetic surveys in Hamilton, 
Pulaski, Newton, Wayne and Fayette Counties. 



Analysis of Gravity and Magnetic Data 

Lithology 

Regional studies of the statewide gravity map (Fig. 1A) and average 
aeromagnetic map (Fig. IB) begin with two simple assumptions: 

1) The source of the anomalous gradients on both maps arise from 
lithologic changes within the basement complex (the top of the basement 
is 2,000 to 11,000 feet below sea level). The anomalies are not an expres- 
sion of topographic relief on the basement surface. Lateral changes in 
density and magnetic susceptibility in the overlying sedimentary section 
are also not sufficient to create the anomalous contour patterns displayed 
on these maps. 

2) Areas of high gravity values are underlain by dense rocks within 
the basement. Areas of high magnetic values are underlain by rocks with 
a relatively high content of magnetite (an iron oxide mineral common 
to certain igneous and metamorphic rocks).

Map of Indiana showing Precambrian provinces derived from gravity and 
aeromagnetic data. 



Figure 4. Map of Indiana showing structure on top of the Precambrian basement. 
( modified from ( 2 ) , Fig. 11). 



With the above assumptions, we have studied the statewide maps 
(Fig. 1) and generalized areas of extreme high and low values. Figure 
3 identifies areas of basement lithologies associated with either dense 
or magnetic rocks or combinations thereof. For example, the stippled 
pattern throughout the central part of Indiana (and isolated areas on the 
western and southern edges of the state) delineate areas of low density- 
low magnetic rocks. This combination could represent metamorphosed 
sediments, or, perhaps a weathered granitic terrain. Magnetite-rich dense 
basalts (the cross-hatched pattern) could underlie the magnetic and dense 
areas to the northwest and southwest. A magnetite-rich zone of granitic 
rocks would explain the strong magnetic region in southwest Indiana 
(heavy diagonal pattern) and a very basic, but magnetite-poor lithology 
might produce the isolated region in north central Indiana (light diagonal 
pattern). 

Studies of lithologies in the midwest (7) indicate that the average 
Precambrian terrain may be granitic in nature and we suggest that the 
areas labeled as "intermediate" basement rock in Indiana is a granitic 
country rock. 

Depth 

Studies of individual gravity and magnetic anomalies can yield 
estimates of a minimum depth to the top of the lithologic source of the 
anomaly. Henderson and Zietz (2) used 79 isolated well defined magnetic 
anomalies for depth calculations. Combining their results with seven deep 
wells, they constructed a generalized contour map of the basement surface 
(Fig. 4). Since the original work by Henderson and Zietz, there have been 
12 additional basement wells drilled and extensive seismic reflection

coverage (5, 6). None of these data have been incorporated into 
Figure 4. 

There are several recent publications which represent the Indiana 
basement surface to be a smooth topographic surface {e.g., 1) ; it is our 
belief that the differences between the Henderson and Zietz interpreta- 
tion and more recent versions are primarily due to lack of control. Recent 
maps use only deep test wells and these are poorly distributed, generally 
confined to the central part of the state along the Cincinnati Arch. The 
basement map based on magnetic analysis depends on numerous, widely 
distributed control. 

Geometry of Basement Intrusives 

We have earlier suggested that the source of many of the gravity 
and magnetic anomalies be within the Precambrian basement. Various 
rock types intruded into the granitic country create a lithologic contrast 
responsible for the observed anomalies. It is a curious observation that 
many of these anomalies are concentrated along the Cincinnati Arch (out- 
lined by the heavy lines in Figure 1). Detailed studies of two of these 
anomalies have been moderately successful in defining the geometric and 
lithologic sources.

Figure 5. Schematic representation of Precambrian bodies interpreted as sources for 
the gravity and magnetic anomalies observed in A) Pulaski and B) Hamilton Counties. 



Area A in Pulaski County (Fig. 1) is an isolated, well-defined anomaly 
approximately circular in form (Fig. 5A). Analysis of seismic, gravity 
and magnetic data (8) suggest that the source is a vertical, prismatic 
body of basaltic material intruded into a country rock of granite. Area B 
in Hamilton County (Fig. 1) is also a well-defined anomaly, but more 
complex in its form (Fig. 5B). In a recent study we suggested that 
the source of this anomaly is a vertical pipe, with a series of overlying 
flow-like sheets of basalt (9). 

Viewing the interpretation of these two anomalies as part of a larger 
geologic picture, the Cincinnati Arch appears to be the site of numerous 
intrusive pipes, now represented by a concentration of magnetic anomalies. 
These intrusions were sources for flow-like basalts that covered the 



228 Indiana Academy of Science 

Precambrian surface in isolated patches. We encountered flow-like basaltic 
rocks in several of our basement tests and this interpretation thus seems 
geologically reasonable. The age of the intrusions and flows is question- 
able, but it is suggested that they may be Keweenawan related.

History of Brick Manufacture in Indiana 1 

George S. Austin and John B. Patton 

Indiana Geological Survey 

Bloomington, Indiana 47401 

Abstract 

In Indiana bricks were commonly burned at the construction site in the first 
decades of the 19th century, but by 1840-1860 centralized brickyards were operating in 
or near most communities. Pennsylvanian shales and underclays, Mississippian and 
Devonian shales, leached glacial drift and alluvium, and residual soils have supplied the 
raw materials for common brick, face brick, paving brick, and firebrick manufactured 
during the 19th and 20th centuries. 

The brick industry has progressively centralized to fewer but larger installations 
concentrated near particularly favorable shale and clay supplies. By 1971 less than 200 
million bricks were manufactured in only 12 plants in Indiana, but the annual value of 
the product had grown to nearly $8 million. This stable industry will continue 
indefinitely to be a significant factor in Indiana's economy. 

Introduction 

Indiana has long had a flourishing ceramics industry that has 
contributed substantially to the economic growth of the State. Plants 
producing building bricks have added aesthetic quality to Indiana towns 
and landscapes (Fig. 1).

Little was recorded concerning the early history of the brick industry 
in Indiana. In 1833, the second edition of Scott's The Indiana Gazetteer 
(18) had only one description of brick clay, although brick buildings were 
recorded in nearly every community. Much of the brick for major 
structures, small groups of buildings, and isolated localities was burned 
at the site by itinerant craftsmen who specialized in this skill. The magni- 
tude of brick manufacture may be judged from Scott's description (18) 
of Charlestown, in Clark County: 

"The public buildings are a court house, a jail, an office for the clerk 
and recorder, and a market house, all of brick; in addition to which 
the Episcopal Methodists, the Reformed Methodists, the Baptists, 
and the Presbyterians, have meeting houses, all of brick, and an 
extensive brick building has lately been erected for the purpose of 
a county seminary . . . There are in Charlestown, about sixty-five 
brick dwelling-houses, and about a hundred of wood." 

It is known that by the 1840's and 1850's almost every 
community in the state had a brick yard that manufactured common 
brick (11). Some clay deposits and ceramic plants were briefly identified 
by early authors ranging from David Dale Owen in 1839 (17), through 
Cox (9, 10), and Collett (7, 8), to Maurice Tompson in 1886 (19), and W. 
H. Thompson in 1889 (20), but these reports were short and offered little 
basic information on the extent and geology of the deposits and the 
facilities at the factories. 

In 1895 the newly appointed State Geologist, W. S. Blatchley, began 
to gather information concerning the clay and shale resources of Indiana.

This inquiry led to the 1896 publication of a report (2 and Fig. 2) on the 
clay and related industry of some counties in southwestern Indiana. Two 
years later a report on the clays and the clay industry of northwestern 
Indiana followed (3 and Fig. 2). Blatchley's work on clays culminated 
in the publication, in 1906, of a very extensive report on the clays of the 
entire state (4 and Fig. 3). 

Logan (15) presented some information about the clay industry in 
the Handbook of Indiana Geology, published in 1922, and in 1933 Whit- 
latch (21 and Fig. 4) published a comprehensive study on the clay 
resources of the state. Whitlatch's report, which was his Ph. D. disserta- 
tion, updated Blatchley's information on the clay industry and also 
emphasized the regional geology of the clay deposits.

Since 1933, publications on the development of the clay industry have 
been limited to five directories (1, 6, 12, 14, 16) of the producers and users 
of clay and shale. Geological aspects of the clays have been explored in 
one publication (13), and numerous reports have been issued on special 
aspects of clay mineral research. 



Regional Geology of Indiana Clay and Shale Deposits 

The clays of Indiana can be divided for discussion into eight types 
or regions (Fig. 5) : 1) Pennsylvanian shales and underclays are near the 
surface and readily accessible in southwestern Indiana; 2) lying just east 
of these exposures are shales of the late Mississippian Chesterian Series; 
3) in the south-central part of the state, clays lying above the middle 



232 Indiana Academy of Science 

Mississippian limestones comprise a central residual belt, and 4) east of 
this belt are the shales of the early Mississippian Borden Group; 5) to 
the east of the Borden outcrops are exposures of the New Albany Shale, 
and 6) in extreme southeastern Indiana residual clays lie above limestones 
of Devonian and Silurian age and limestone-shale sequences of Ordovician 
age. A seventh type of clay material is obtainable at numerous places in 
northern Indiana, where glacial drift that includes both till and glacial 
lake sediments can be used as raw material for a ceramic industry. An 
eighth type of ceramic raw material consists of alluvial clays which are 
related to present-day streams at various localities throughout the state, 
and of leached loess found in the southwestern part of Indiana. 

In the 19th century and the early part of the 20th, all of these eight 
types of materials were used by plants producing brick from local raw 
material. As the 20th century progressed, the brick industry consolidated, 
not only because of the greater efficiency of larger plants but also because 
of the superior product that could be manufactured from proper materials. 
In addition, modern rail and truck transportation provided enlarged 
market areas. Smaller and less efficient plants were abandoned. Small 
kilns were replaced by larger ones. Wood as fuel was displaced by coal, 
which in turn is being replaced by natural gas. Round periodic kilns are 
giving way to continuously fired tunnel kilns. With growth and automa- 
tion, very accurate control is necessary over all parts of the brick- 
making process to produce modern bricks with their wide range of 
predetermined colors and textures. Clay or shale units that vary greatly 
in composition or are thin or interbedded with other types of rocks gen- 
erally have been eliminated as a source of raw material. Unusual rocks 
or minerals are tolerated only if they can be removed by screening or their 
deleterious effects minimized by grinding and dispersion. Residual clays 
overlying various carbonate rocks in southeastern and south-central Indi- 
ana and leached alluvial clays throughout the state are not adequate. The 
thin shales of the Chesterian Series, the carbonaceous New Albany shale, 
and the commonly variable glacial till have generally been eliminated. 

Only shales and siltstones from the Borden Group, a thick sequence 
of fine-grained Mississippian rocks in south-central and west-central 
Indiana, and several of the thick shales of Pennsylvanian age found in 
southwestern Indiana are commonly used in the production of brick. Some 
brickyards using these materials also consume a lesser amount of the 
kaolin-rich clay that underlies certain coalbeds in the western part of the 
state. Kaolin clays increase the firing temperature, widen the firing range, 
and decrease the firing shrinkage of bricks made from rocks of the Borden 
Group. For the few firebrick still made in Indiana, underclays are used. 

Only one plant, at Munster in northwestern Indiana, now produces 
brick from glacial materials, but it does have the sizable production 
capacity of 260,000 bricks per day. The raw material comes from a very 
clayey, homogeneous till about 22 feet thick. 

Types of Bricks 

Structural clay products, including common, pressed, and face brick, 
structural tile, and drain tile, have consumed most of the clay industry's 



Geography and Geology 233 

output. Paving brick was an important product near the turn of the cen- 
tury, but this phase of the brick industry has been almost entirely 
abandoned. Firebrick for high-temperature ovens, furnaces, and kilns has 
been made in Indiana for many years. Indiana's fire clays are still well 
known and marketed in other states, but now only one Indiana company 
produces firebrick. 

The methods used to produce common brick early in the state's 
history were some of the most simple processes in the manufacture of 
ceramic ware, and they have been entirely replaced by other techniques. 
Until the latter part of the 19th century, most building brick in Indiana 
was made by the soft-mud process. Sandy clays were mixed in a pug mill 
and either hand molded or forced into sanded molds. The resulting shapes 
were sun dried or air dried and then burned in kilns, which in their most 
primitive form were built around the stacked unfired bricks. Sandy clays 
of the alluvial or loessial types were used for the soft-mud process. The 
annual production of common brick by most companies operating in 1904 
was small, commonly only a few hundred thousand. 

In the late 1800's, dry-pressed brick replaced some of the soft-mud 
variety, but the process was primarily used in the construction of terra 
cotta and hollow building blocks. Moisture content was kept to the mini- 
mum that would allow shaping by compression into molds, and the result- 
ing products were denser and underwent less shrinkage. The raw ware 
contained only 7 to 10% moisture, but moisture content was 20 to 25% 
in the soft-mud process. 

The use of brick for bearing walls in building construction decreased 
progressively from shortly after the turn of the century, and pleasing 
texture and color became relatively more important as brick came to be 
used mainly for facing. Face brick is produced more satisfactorily by the 
dry-press and stiff-mud methods than by the soft-mud process. 

Since about 1920, face brick produced by the stiff-mud process has 
been the principal product of the brick industry. A plastic clay mixture 
is dewatered by vacuum to 12 to 15% moisture content and this is extruded 
continuously through a die by auger or plunger pressure. Length and 
width of the brick are controlled by the die, and thickness is established 
by cutting the extruded bar at desired intervals. 

Changes in the Brick Industry 

From the 1840's and 1850's, when nearly every community had a brick 
yard, to the 1890's and early 1900's, when brick as a construction material 
was at its zenith, the quantity of brick produced grew steadily. At the 
turn of the century most brick companies were still small, and therefore 
their number was great. When W. S. Blatchley visited Evansville in 1895, 
he recorded (2) that 21 brick yards were operating within 2 miles of the 
county courthouse. In 1905, more than 200 companies in Indiana were 
producing brick. Of this total, eight used the dry-press process and the 
rest used the stiff-mud, soft-mud, or hand processes to produce common 
brick. In 1904, almost 300 million common bricks were produced by these 
plants, although a high of 315 million had been reached earlier in 1901. 



234

In addition, about 30 million pressed bricks, 50 million vitrified or paving 
bricks, and lesser amounts of firebrick and ornamental material, such 
as terra cotta, were produced. The total value of these products for that 
year was $2,640,313. Only 34 companies were listed in 1922 in the Hand- 
book of Indiana Geology (15), and even though the list is incomplete, the 
great change in the number of companies involved in brick making, as 
expressed by the numbers of companies in 1905 and in 1919 when data 
for the Handbook were collected, reflected the change in the building 
industry in Indiana. The use of common brick was reduced, and wood con- 
struction replaced much of the former brick construction. By 1933, when 
a more complete record of brick plants was made (21), 47 plants produced 
brick, and most used the stiff-mud process. According to Whitlatch's 
figures, in 1929 about 112 million common bricks, 130 million face bricks, 
and 3% million paving bricks were produced. Fire clay refactories, com- 
posed mostly of firebrick, totaled almost 6 million bricks or the equivalent. 
The total number of bricks was 252 million, valued at $3,565,823. In 1970 
only 12 brick plants remained in the state (Fig. 6), and they produced 
about 186 million bricks. The value of these bricks was nearly $8 million. 
The value of face brick amounted to more than 80% of that total, and the 
remainder came from sales of common brick. 

The brick industry has responded to the modern trend toward the 
construction of modular homes by the building trades by producing pre-

formed brick panels. These panels, which are made with normal or thin 
brick, are fabricated at the plant, moved by truck to the construction site, 
and hoisted into place by cranes. 

Distribution of Brick 

The many small companies that operated in Indiana near the turn 
of the century probably did not ship their products more than a few miles ; 
however, some larger companies were able to transport their products 
to destinations many states away. In 1904 the Hoosier Brick Company 
of New Albany shipped common bricks by rail throughout southern Indi- 
ana and Kentucky. During the same year the Cayuga Brick and Coal 
Company of Vermillion County shipped most of its common brick to 
Chicago. Dry-pressed brick made at Hobart in Lake County were sold in 
Philadelphia, Milwaukee, St. Paul, St. Louis, and other cities. The Indi- 
ana Paving Brick Company of Brazil began operations in 1891, and by 
1904 it was using local shale blended with sand from the shores of Lake 
Michigan. Paving bricks were shipped from the plant to the larger cities 
in Indiana and to Cincinnati, Louisville, and many towns in Illinois. Indi- 
ana refactory bricks were well known in 1904, and the Burns and Hancock 
Company of Vermillion County had supplied firebrick to states as far away 
as Montana, Georgia, and Alabama. 

At present most companies find their market within a 200-mile 
radius of their manufacturing facilities. 

Summary 

In summary (Fig. 7), by 1900 Indiana's brick industry consisted of 
more than 200 plants that were distributed broadly throughout the state, 
that used virtually all types of suitable clay materials, and that produced

more than 300 million brick a year with an annual value of nearly $2 
million, predominantly for common brick. Progressively through the sub- 
sequent 70 years the number of plants has decreased to the present 12, 
the raw materials have been restricted largely to Pennsylvanian shales 
and underclays and lower Mississippian shales and siltstones, the annual 
volume has decreased by one-third to slightly less than 200 million brick, 
and the annual value of the product has grown to nearly $8 million, partly 
because of inflation and partly because most of the product is face brick 
with higher unit value. This is a portrait of a stable industry — one that 
has lost more ground in relation to the gross state product than is readily 
apparent from the production figures, but one that is continuing to change 
with advances in the construction industry and seems likely to continue 
indefinitely as a significant element in the Indiana economy.

A Comparison of Public Utility and Governmental Rates and 
Services Provided Mobile Home Park Residents and Other 
Residents: A Case Study of Tippecanoe County, Indiana 

Alan C. Freeman and George W. Webb 

Department of Geography and Geology 

Indiana State University, Terre Haute, Indiana 47809 

Abstract 

This study involved a determination of whether services and rates received by 
mobile home park residents differed from those received by other residents of the 
county. Differences between these two classes of residents in public utility rates and 
services were not found in the study area. With the exception of fire protection, 
mobile home park residents receive governmental services comparable to those received 
by other residents of the area. The principal variation in rates and services are those be- 
tween locations inside and outside the municipal boundaries rather than those between 
residents of mobile home parks and other residents. 

Introduction 

Mobile homes now account for about 94% of ail housing units sold 
in the U. S. for under $15,000 and for 2/3 of all housing units costing 
less than $25,000. The mobile home business is one of the fastest grow- 
ing industries in the country today. Because of this growth the number 
of mobile home parks has increased at a rapid rate. 

A literature search revealed no prior investigations comparing 
quality and costs of public utilities and government services received 
by mobile home park residents with those received by other residents. 
Tippecanoe County, Indiana, situated in the west-central part of the 
state, was selected for such study. 

In 1970 a total of 109,378 persons resided in Tippecanoe County, 
according to the United States Census of Population. This was an in- 
crease of 20,256 persons over the 1960 census figures. Lafayette, 
located in the north-central part of the county, is approximately 60 miles 
northwest of Indianapolis and 120 miles southeast of Chicago. Lafayette 
had 44,955 persons while West Lafayette contained 19,157 persons, in 
1970. Purdue University, with about 25,000 students on the home campus 
is located at Lafayette. A large number of the university students reside 
in mobile homes. The size and growth of the population, the presence 
of Purdue University, and the locational advantages for industrial 
development, along with the number of mobile home parks, were the 
reasons for selecting Tippecanoe County, Indiana, for the study. The 
purpose of the study was to determine whether or not the residents of 
mobile home parks were subjected to differences in governmental serv- 
ices and public utility rates from the rates and services received by other 
residents of the study area. 

Method 

The data were obtained by holding personal interviews with the 
proprietors and/or managers of the mobile home parks and with the 

238 



Geography and Geology 239 

public utility companies and municipal departments which supply serv- 
ices to the area. 

The public utilities were the Public Service Company of Indiana; 
Tipmont Rural Electric Membership Corporation; General Telephone 
Company of Indiana; Indiana Gas Company, Incorporated; The City 
of Lafayette Water Works and Sewage Treatment Department; The 
West Lafayette Water Company; The City of West Lafayette Sewage 
Treatment Department; and the Greater Lafayette T.V. Cable Service. 

Governmental services included the following: maintenance of 
streets, curbs, and street lights, police protection, fire protection, and 
mail delivery. 

Findings 

It was found that a difference in rates for electrical service exists 
in Tippecanoe County only in that Public Service, Indiana, In- 
corporated, has two rate schedules, one for the urban areas and another 
for rural areas. No rate differentiation is made between mobile home 
park residents and other residents in the same rate schedule area. 

Electrical service is made available to the mobile home park as 
freely as to any other residential development in the county. Public 
Service Indiana has encountered no major problems other than that of 
congestion of lines with the other public utilities during the period of 
construction. 

Indiana Gas Company, Incorporated, sets no rate differences among 
its various types of customers. One distinction is made in that mobile 
home park residents are placed in the same class as customers who rent, 
buy on contract, or live in an apartment. All of these residents are re- 
quired to pay an $13.00 deposit before the gas company will provide 
service to the unit. 

Gas service is made available to any developer who wishes to make 
a deposit equal to the cost of construction in case the gas company does 
not feel it is economically sound for it to pay the initial cost. The 
Indiana Gas Company does not face any major problems in bringing 
service to the mobile home park resident other than that faced by other 
utilities, the congestion of lines during the construction period. 

A comparison of rates for water service in the mobile home parks 
with other residents of the county revealed no difference between the 
two; however, service was not as freely available to the mobile home 
parks, primarily because it is not economically sound for the mobile 
home park developer to pay for the construction of water lines when 
he can drill his own well at a much lower cost. When service is extended 
beyond the city limits of Lafayette the Board of Works decides who 
will absorb the cost of construction for the water and sewage lines. 
In West Lafayette the water company will not provide service to a 
mobile home park unless the developer makes a deposit equal to the 
cost of construction which is estimated by the West Lafayette Water 
Company prior to the construction. It should be noted that the majority

of the mobile home parks are located just outside the municipal 
boundaries (Fig. 1). 

A developer may construct his own sewage lines and connect them 
to the city's lines without having city water service if he is able to 
obtain a permit by the city. However, it is more economical for the 
developer to install septic tanks than to pay the cost of construction 
of city sewage lines. No park in the study had city sewage without city 
water service. 

General Telephone Company of Indiana assigns its rates by zones 
with Lafayette as the base area. No distinction is made between 
mobile home park residents and other residents. A mobile home park 
resident will, as will any other resident, pay a rate dependent on the 
zone within which he is located. 



Geography and Geology 241 

Telephone service is available to all of the mobile home parks in- 
cluded in the study. The major problem faced by General Telephone is 
the strain placed on the central office as service is extended to a new 
area. 

The Greater Lafayette TV Cable Service Company does not dis- 
tinguish between mobile home park residents and other residents when 
establishing rates. However, the parks are treated as apartment 
dwellings in installation and rate determination. This classification 
often produces a rate which is lower than that for other residents. Only 
six mobile home parks have cable T.V. service. The major problem is 
again the congestion of lines. 

In the area of fire protection the mobile home parks, because of 
being located mostly outside the municipal boundaries, generally do 
not receive the same level of service as do the residents of Lafayette 
and West Lafayette. Parks located outside the municipal boundaries 
must rely upon volunteer departments. Such units require an average 
of approximately 25 min. to respond to calls, too long a time for the 
department to be effective in extinguishing a mobile home fire. As a 
result of being located relatively close to fire stations, municipality resi- 
dents can be reached more quickly by the full-time fire fighting units. 

Police protection of mobile home parks is comparable to that of 
the other residents of the county. The mobile home parks located cut- 
side the municipal boundaries are protected by the Sheriff's Office and 
the Indiana State Police. The parks within the municipal boundaries 
are protected by the municipal police departments. 

Maintenance of streets, curbs, and street lights alongside the mobile 
home park is also at the same level of service as that of any other area 
within the county. The streets, curbs, and street lights within the parks 
are the responsibility of the park owner. 

The United States Post Office Department furnishes the same 
service to the residents of the mobile home parks as to the other resi- 
dents, the postman going to each unit in the park. 

In summary, it can be stated that there are no differences between 
the mobile home park residents and other residents in rates of the public 
utilities, and that service is available to any park if the developer wishes 
to make the investment when the public utility does not feel it is 
economically sound for it to do so. 

With the exception of fire protection, in the area of governmental 
services the mobile home park resident receives comparable service to 
that received by other residents who are similarly located. In general 
it can be concluded that the principal variations in rates and service 
are those between locations inside and outside the municipal boundaries 
rather than those between residents of mobile home parks and other 
residents. 



Heavy Water A Natural Tracer 

Clark H. Judy 

Department of Geography 

Ball State University, Muncie, Indiana 47306 

Abstract 

All naturally occurring water contains a small percentage of isotopically heavy 
water molecules. The processes of vaporization and condensation affect the 
concentration of the heavier water molecules. The changes in concentration of heavy 
water molecules have been used to study the origin of winter storms, to determine 
evaporation rates from lakes, and in studies of water movement. 

Introduction 

Three common heavy water molecules occurring in nature are HDO, 
HTO, and H 2 Ois. HDO and H 2 Oi® are stable (non-radioactive) 
isotopic forms of water and comprise 0.015% and 0.20%, respectively, of 
naturally occurring water. HTO is radioactive and emits low energy 
beta radiation. A small amount of HTO occurs naturally, but the use 
of nuclear devices has increased the amount of HTO in the hydrologic 
cycle. 

The "heavy water" associated with nuclear projects, D 2 0, is not 
important in natural water supplies as it tends to break down and cause 
the formation of HDO. 

Scientists usually work with the natural or bomb-introduced 
concentrations of heavy water. But, sometimes it is possible to 
utilize small amounts of artificially concentrated heavy water for a 
specific study. The concentrations of HDO or H 2 18 in a water sample 
are usually measured with a mass spectrometer. A liquid scintillation 
counter must be used to measure HTO. 

The use of isotopically heavy water as a tracer of water movement 
is best explained through a series of examples. First, two concepts must 
be explained. 

The vapor pressure of heavy water is slightly less than the vapor 
pressure of H 2 16 at the same temperature. This will cause a slight 
fractionation to occur whenever the processes of evaporation or conden- 
sation takes place. During evaporation the heavy molecules tend to 
become concentrated in the liquid phase while the vapor phase has a 
higher percentage of light molecules. During condensation the heavy 
molecules will tend to condense out more rapidly causing the first 
condensate to be enriched with heavy molecules and the remaining 
vapor to have a greater percentage of light molecules. 

The heavy water content of a sample is often given as the per cent 
deviation of the heavy isotope content of the sample relative to the 
heavy isotope content of average ocean water. A sample of precipitation 
with a HDO content reported as —7% contains 7% less HDO

molecules than ocean water, namely a reference water (SMOW, 
standard mean ocean water, as recommended by Craig- ( 1 ) ) . Precipitation 
is usually isotopically lighter than ocean water. 

Examples 

The change in the heavy isotope content of a body of water can 
be used to determine the evaporative loss from that body of water. The 
water entering a large lake has an average HDO content of —8.3% 
and the discharge from the lake has a HDO content of —7.6% 
(Fig. 1). These measurements indicate that fractionation during 
evaporation caused an enrichment of the heavy isotope content of the 
lake water. A knowledge of the amount of increase of HDO in the lake 
and the vapor pressures of H 2 and HDO allows one to calculate that 
15% of the original volume of water has evaporated.

Evaporation based on heavy water content = 15% 

Figure 1. Diagram of heavy water — evaporation relationships of a lake. The amount 
of evaporation from a lake can be determined by comparing the HDO content of the 
incoming water with the HDO content of the outgoing water. Diagram after Friedman 

et al (1964). 



On a larger scale, we can follow the changes in the HDO content 
of the moisture in a storm system (Fig. 2). The HDO (and 
H 2 18 content of precipitation is controlled by the amount of condensa- 
tion and the temperatures at which this condensation takes 
place. The moisture evaporating from the ocean will be isotopically 
lighter than the ocean water. As the processes of evaporation and con- 
densation are opposite, the first condensate from the air mass will have 
about the same heavy isotope content as the original ocean water. As 
the air mass moves farther inland it will become depleted in heavy 
molecules and the resulting precipitation will be isotopically lighter. 
Snow is usually isotopically lighter than rain and high altitude precipi- 
tation is usually lighter than low altitude precipitation. 

In California, isotope measurements have been used as an indication 
that during a winter of heavy snowfall there may have been a change 
in circulation patterns not detected by the conventional meteorologist. 
An extensive series of HDO or H 2 18 measurements should help the 
meteorologists obtain some quantitative information on the processes

occurring in the atmosphere. The main problem is a lack of sufficient 
available data on the heavy isotope content of precipitation. 

The variation in the heavy isotope content of precipitation may 
be used in some hydrologic studies. Perhaps a city near a mountain 
range is dependent upon ground water for a public water supply and 
the city would like to determine the recharge area of the aquifer they 
are using (Fig. 3). Basic information could be obtained by measuring 
the heavy isotope content of the ground water and comparing it to the 
heavy isotope content of precipitation in various areas. If the well water 
was isotopically light, it could be assumed that the recharge area was 
high in the mountains. 

The uses of the isotopically heavy forms of water are not limited 
to those just mentioned. HDO has been used in snowmelt studies, to

help date layers of ice in glaciers, to trace the movement of soil mois- 
ture, and in biological studies. The list of references that follows 
expands on several of the applications. Friedman et al. reviewed 
much of the work done with HDO (3). Dansgaard reviewed some of the 
work done with H 2 ls (2). 

There are several advantages to using heavy water as a tracer of 
water movement. Water is actually being used to trace water, so there 
is little problem with the selective absorption of an introduced tracer. 
HDO and H 2 18 are naturally occurring and are not radioactive so 
people will not be upset by their use. The slight fractionation upon 
evaporation and condensation allows a quantitative measurement of 
many hydrological and meteorological processes. 

There is one disadvantage. The cost of sample analysis (currently 
about $50 per sample) is high. This has restricted the accumulation of 
large amounts of data and background knowledge about HDO and 
H 2 18 in the hydrologic cycle.

A Preliminary Investigation of Sludge 
Refuse from Indiana Coal Mines 1 

Louis V. Miller 

Indiana Geological Survey 

Bloomington, Indiana 47401 

Abstract 

Seven samples of fine refuse (sludge) were collected from two coal mine refuse pits 
located in Greene and Sullivan Counties. Particle size distribution was determined. 
Proximate and ultimate analyses of the sludge refuse were determined and compared to 
a "whole coal." The data indicated that the British Thermal Unit content of sludge refuse 
was about 75 per cent of that of the "whole coal" on the moisture-free basis, but was 
almost similar on the moisture-ash free basis. Based on chemical parameters, sludge 
refuse should be considered a natural resource for future fuel use and should be reclaimed. 

Before coal can be used by industry, it must undergo a preparation 
process at the mine site. This process consists of crushing, washing, 
de-watering, and sizing of the coal. During the washing cycle, refuse 
(pyrite, shale, clay, calcite, rock, high-gravity coal, etc.) is separated 
from the coal. 

Coal preparation produces two kinds of refuse: 1) a coarse particle 
refuse ("gob") that may be several inches in diameter; and 2) a fine 
particle refuse ("sludge" or "tailings") that may be 1/8 inch or less 
in diameter. For brevity the terms "gob" and sludge are used in this 
paper. Sludge contains larger percentages of coal than does "gob." Total 
refuse can, periodically, account for as much as 45% of the total daily 
raw coal (unprepared coal) production. Generally, the average 
percentage for sludge is 3-7% and for gob 9-15% of total daily raw coal 
production. 

Within the 22 years preceding 1970, Indiana mines produced 
370,022,689 tons of salable coal (M. B. Fox, personal communication). 
Because almost all of this coal underwent the preparation process, the 
average percentages (sludge — 5% and "gob" 12%) may be used to 
calculate the amount of refuse produced. Calculations indicate that 
during the 22-year period 136,857,706 tons of refuse were produced of 
which 40,326,165 tons were sludge. 

Sludge produced from the preparation of the following coal mem- 
bers is considered in this paper: 1) Survant Coal (IV), 2) Springfield 
Coal (V), 3) Hymera Coal (VI), and 4) Danville Coal (VII) (2). 

Greene County 

The Greene County sludge pit covered an area of 80-90 acres from 
which Samples #4, 6 and 5 were taken (in that order). The interval be- 
tween samples was 3,000 feet. Sample #4 was 1,000 feet from the point 
of sludge entry into the pit. For observational purposes, additional

samples were taken at 100 feet intervals between Sample Sites #5 and 
6. Between these sites there was an apparent change to smaller 
particle size and to a "dirty gray" color. 

Sullivan County 

The Sullivan County sludge pit covered a 70-acre area from which 
Samples #13, 14, 11, and 12 were collected (in that order). Sample 
#13 was the nearest to the point of sludge entry (about 400 feet). The 
interval between samples was about 425 feet. 

Methods 

Seven sludge samples were collected from two sludge storage areas 
(pits) of mines located in Greene and Sullivan Counties. Before 
sampling, about 10 inches of sludge surface was removed and then the 
sample was taken with the use of a post hole digger to a depth of 4 feet. 
The sample filled a 5 gallon can. 

Sample preparation and subsequent chemical analysis followed the 
procedures and specifications of ASTM-D-271-58 (1). After collection, 
the samples of sludge refuse were air dried so that their moisture con- 
tent was in equilibrium with that in the atmosphere. Each sample 
was thoroughly mixed and then split into four equal parts. Two of the 
parts (making up 50% of the original sample) were mixed back 
together to form the sample for the particle size determination. Of the 
remaining two quarters, one was put into storage for future work and 
the other was used for chemical analysis. 

The chemical analysis consisted of determining moisture, ash, 
volatile, fixed carbon, total carbon, nitrogen, hydrogen, and sulfur along 
with the BTU and the C0 2 . These data for sludge are compared with 
the data from "raw coal." The Greene County sludge is compared with 
Coal V while the Sullivan County sludge is compared with Coal VI. 

The screening of the air-dried sample was accomplished with the 
use of U.S. Standard sieves and a Tyler Ro-Tap sieve shaker. The sieves 
had square opening sizes of 8, 16, 32, 100, and 200 mesh. 

Results and Discussion 

On the moisture-free basis the data indicate that sludge from the 
Greene and Sullivan County pits is inferior to their respective compara- 
tive coals (Tables 1 and 2). However, if data on the moisture-ash free 
basis are considered, it is found that the differences are reduced and 
that similarity of the materials is emphasized (Tables 1 and 2). 
Samples #13, 14, and 11 of the Sullivan County pit exhibit the 
idealistic pattern ; that is, higher ash and lower BTU nearer the point of 
sludge entry into the pit progressing to lower ash and higher BTU 
farther away (Table 2). Sample #12 appears to be the maverick in the 
group with its high ash and low BTU; but the data in the particle size 
histogram of Figure 1 indicates that Sample #12 had a high percentage of 
fine particles (other data determined on particle size but not presented 
in this paper indicated that higher ash is located in the finer size).

Conclusion 

The data bore out some of the visual observations. When consider- 
ing the BTU on the moisture-free basis, sludge refuse contains about 
75% of that of the compared coal (Table 2). If the ash can be eliminated 
then sludge refuse and coal are very similar, as indicated by the 
moisture-ash free basis data. Because of the similarity of the chemical 
parameters, and because of the great quantities available (over 40 
million tons), sludge refuse should not be wasted. It should be considered 
a fuel and should be reclaimed for fuel purposes.

The Distribution of Slopes in Indiana 

David B. Waldrip and Michael C. Roberts

Bloomington, Indiana, 47401 

Abstract 

Slope maps of Indiana have been prepared from the 2 percent sample of the United 
States Department of Agriculture Conservation Needs Inventory. The Syngraphic Mapping 
Technique (a form of computer cartography) was used to generate maps of average 
slope, slopes between and 2 per cent, and slopes 35 per cent and greater. 

Introduction 

The objective of this study was to develop a quantified slope map 
which would supplement and extend the work of Malott (2) on the 
regional geomorphology of Indiana. A subsidiary objective of the 
research was to provide a slope map, sufficiently detailed, to aid in the 
development of more precise morphometric measures to be used in 
studies of watersheds in Indiana. 

The classical study classifying and describing the physiographic 
regions of Indiana was published by Mallott in 1922 (2). More re- 
cent summaries of the State's physiography are to be found in papers by 
Schneider (4) and Wayne (6). A quantitative approach to the 
physiography of the state is taken by Lewis (1) who used principal com- 
ponents analysis as a method of regionalizing 13 morphometric 
variables. His data were collected from a random sample of 60 fourth 
order drainage basins. The writers believe that Lewis is justified in con- 
cluding that his approach provides a more objective view of Indiana 
physiography. However, any examination of the benefits of objectivity 
as yielded by principal components analysis must be balanced by the 
fact that the physiographic regions, so produced, are rudimentary and 
not particularly informative. 

In the geographic literature there are many reports of research 
dealing with state and regional maps of slope, though none of these 
studies use the mapping techniques and data sources of this paper. Good 
summaries of slope research are to be found in Miller and Summerson 
(3), and Zakrzewska (7). 

Conservation Needs Inventory 

It was recognized in the mid-1950's that changes in land-use 
patterns with their associated problems were taking place rapidly 
enough to necessitate the development of a data bank which could be 
used to monitor these changes. The response to the situation was the 
establishment, in 1957, of the Conservation Needs Inventory (referred 
to hereafter as the C.N.I.) . The major objective of this Inventory was 
to provide the U.S. Government with up-to-date and detailed information 

251

on the rural landscape. The scope of the data is indicated by the follow- 
ing variables which are included in the inventory: land ownership, soil 
type, slope, erosion, land use and treatment needs. The U.S. Department 
of Agriculture wanted the inventory, for the entire country, to be com- 
pleted within 3 years of the starting date in 1957. To achieve these ob- 
jectives, Taylor (5) designed a startified random sample, which used 
the quarter section (160 acres) as its standard sampling unit; a 
sampling rate of 2% was established that required the selection of 3 
quarter sections per township. The Statistical Laboratory of Iowa State 
University in Ames, Iowa, is responsible for maintaining and period- 
ically updating the Inventory which is stored on magnetic tape. 

Analysis of the Data 

The first task of this research was to change the order of the 
C.N.I, variables from a sequence based on soil types to one based on 
counties and townships. This strategy put the data into a locational form 
eminently suitable for computer mapping. 

With the data in the new sequence it was possible to compute the 
average slope value for a township by using the following formula: 

1 N 

Yi = 5 Pj (S q k ) X 100 
3=1 k=l 

S ~ " 

where, Y i = average slope for the i th township 

N = number of soil mapping units in the i th township contain- 
ing at least one acre of slope class j 
Pj = midpoint value of slope class j (%) 
q k = acreage of the k th soil mapping unit 
S = sample acreage of the i Ul township. 

The outer summation refers to the seven slope classes adopted by the 
C.N.I, for Indiana; these are 0-2; 2-6; 6-12; 12-18; 18-25; 25-35, and 
greater than 35% slope. 

Computerized maps of the slope classes were then generated by 
using the Synagraphic Mapping Technique (SYMAP). The geographic 
center of the 1,270 townships used in the Inventory of Indiana served 
as the data points for the maps. 

Slope Maps of Indiana 

Four maps were selected for illustrating the variation of slope in 
Indiana. Included were two average slope maps, and maps of 0-2% slope 
and 35% and greater slope. 

Average Slope Map 1 

This map (Fig. 1) uses the slope class intervals adopted by the Con- 
servation Needs Inventory for Indiana (these values vary from state 
to state). The feature that clearly emerges from the map is the division

of the state into two parts about a line drawn approximately east- 
west through Indianapolis. The slopes of the southern half of the state 
clearly reflect the physiographic divisions established by Malott (2). 
The Wabash and Scottsburg Lowlands are readily identified as are the 
higher average slopes of the Crawford, Norman, and Dearborn Uplands. 
The Mitchell Plain between the Crawford and Norman Uplands can be 
distinguished even though the pattern of low slope is broken into dis- 
continuous units. The northern half of the map is dominated by 1-6% 
slopes reflecting the glacial modification of the landscape north of Indi- 
anapolis. 




Figure 1. The average slope map 1. 



The 0-2% Slope Map 

The value of this map (Fig. 2) to the interpretation of Indiana 
physiography is the emphasis it gives to the occurrence of low slopes, 
which are indicated by the darker shadings on the map. For example, 



254 



Indiana Academy of Science 



the Calumet and Maumee Lacustrine Lowlands are clearly differentiated 
as well as the more extensive Tipton Till Plain to the south. The low- 
lands and floodplains associated with the Kankakee, Wabash and White 
Rivers are well defined areas of low slope. Other features that can be 
identified are the Valparaiso Moraine and the Steuben Morainal Lake 
Area.

Average Slope Map 2 

The class intervals for this map (Fig. 3) are changed from Figure 
1 in that each interval represents an equal range of slope. It is apparent 
that the lowest class interval does not discriminate, very effectively, 
the slope variation in the northern half of the state. The concentration 
of high slopes in the southern uplands of Indiana is more clearly em-

phasized than on the previous map and, again, the Malott physiographic 
divisions are reaffirmed in this area. 



The 35% and Greater Slope Map 

The high slopes, on this map (Pig. 4), are spatially clustered into 
two groups. One group is associated with the bluffs of the Ohio River, 
while the other is a cluster extending NW-SE across the southwestern 
quadrant of the state. This trend line appears to reflect the occurrence 
of particularly high slopes in both the Norman and Crawford Uplands. 
An area of high slope in the central portion of the map reveals a prob- 
lem of widely scattered data points in relation to the SYMAP 
algorithm. The data of one township with a high slope value located 
on the bluffs of the White River are expanded to influence a much larger 
area on the map than exists in reality. This difficulty can be overcome 
when the sample is areally dense enough to prevent the present situation 
of an isolated anomaly from arising.

Conclusions 

The value of the C.N.I, to the physical geographer who is concerned 
with slope research has been demonstrated. The maps produced here 
give insight into the variation of landforms of Indiana for they show 
that physiographic regions are not uniform spatial units but, in fact, 
units possessing internal variations.

Comparative Growth Kinetics of Microbial Bio-Oxidation. Robert 

H. L. Howe, Eli Lilly and Company Tippecanoe Laboratories, Lafayette, 
Indiana 47902. The comparative growth kinetics of microbial bio- 
oxidation was discussed. A number of mathematical explanations were 
devised and compared. For a substrate of high concentration, the 
kinetics of both batch and continuous systems were presented. Illustra- 
tions were given for signifying the difference of the first order 
kinetics and those of higher orders. 

A Survey of Pollution Levels in the Bean Blossom Watershed (Lake

Indiana University Undergraduate Honors Program and Department 

of Microbiology, Bloomington, Indiana 47401. One hundred and 

twenty-two samples were taken from various areas within the Lake 
Monroe watershed by the H-300 Environmental Protection and Planning 
class during the spring of 1971 and analyzed for presumptive coliform 
numbers by the most probable number tube dilution method. Selected 
samples were also analyzed by the confirmed and completed tests. One 
hundred and thirty samples were similarly analyzed from the Lake 
Lemon and Bean Blossom Creek watershed. The detailed maps and 
results of the study are on file at the Indiana State Board of Health. 
Areas within the Lake Monroe area that showed unusually high coliform 
levels were: 1) downstream from the City of Nashville sewage treat- 
ment plant on the north fork of Salt Creek; 2) areas adjacent to boat 
launching ramps; 3) Moore's Creek and Ramp Creek; 4) bottom 
samples from the Fairfax marina; and 5) a number of isolated areas 
in the upper watershed. The swimming beaches and the center of the 
lake showed a negligible coliform level. In contrast to the low levels 
of coliform in the relatively undeveloped Lake Monroe watershed, the 
Lake Lemon and Bean Blossom watershed showed 100 presumptive 
coliform or greater per milliliter in more than 20 of the samples taken. 
These high coliform levels in a similar and adjacent unprotected water- 
shed point out the necessity for continued environmental protection of 
Lake Monroe watershed by the Indiana State Board of Health. 

The Use of Pollution Surveys as Aids in Environmental Protection and

a large number of students both in courses and during independent study 
have conducted pollution surveys from this laboratory (e.g., the 
H-300 survey of Lake Monroe) upon the request of conservation and 
environmental groups and city and county planners. In these surveys 
we have tried a number of different procedures and survey methods, 
some of which may have utility especially to biology classes in 
Indiana's primary and secondary schools. It is to be anticipated that 
there will be an increasing number of public pollution surveys conducted 
by classes in Indiana schools and universities, and, in order for these 
surveys to have their desired effect, the following suggestions are 
offered: 1) The use of Difco Endo LES agar rather than the presump- 
tive coliform tube test. It is a better teaching aid and is much more 
selective than other liquid or solid media. It is so highly selective for 
coliform that schools without sterilizing equipment for sterilizing media 
will be able to use it without any problem provided they make it up fresh 
before each use and protect it from light. We have found that 0.1 
milliliter of water sample spread over the surface of the agar is usually 
sufficient for the determination of the number of coliform in most 
samples. However, a series of samples should be prepared if millipore 
filters are used to sample larger volumes since high bacterial growth 
may obscure the identification of coliform colonies, giving a false 
negative test. 2) Coordination with local and state regulatory agencies 
both in the planning and in the interpretation of the results. There is 
increasing evidence that the number of fecal coliforms is more closely 
related to the level of sewage pollution, and, although this test is not 
unusually difficult, it is best that some duplicate samples be done by 
experienced bacteriological laboratories such as the Indiana State Board 
of Health. 3) Cooperation with local city and county planners so that 
survey information will be as useful as possible in deciding the future 
extent and location of development as well as simply pointing out present 
problems. 

NOTE 

The Impact of Water Pollution on Recreational Areas in Delaware County. 

Stanton C. Burt, Department of Microbiology, Indiana University, 

Bloomington, Indiana 47401. The contamination of lakes, rivers, and 

their tributaries with fecal material often results in the conversion of 
recreational areas into health hazards. This is an extensive problem 
which can be combated most easily by the application of state laws 
through local agencies. 

Methods and Materials 

The procedures followed for the determination of coliform group 
are those in Standard Methods for the Examination of Water and 
Wastewater published by the American Public Health Association. The 
"presumptive" and "confirmed" tests were performed before the applica- 
tion of the MPN chart. 

Results 

During the summer of 1971, Muncie Creek, which empties into White 
River within McCulloch Park, had an average coliform count of 130,000 



Microbiology and Molecular Biology 261 

organisms per 100 milliliters as it flowed through the park. The Muncie 
Mall and Marhoefer Packing Company outflows were investigated as 
possible contributers to this situation. Two-thirds of the Muncie Mall 
samples exceeded the million organisms per 100 ml. The Marhoefer 
samples varied from a low of 240,000 to a high of 1,100,000 
organisms per 100 ml depending upon the time of day they were 
taken. The Regulation SPC 1R-2, Water Quality Standards For Waters 
of Indiana, states that "Coliform group (is) not to exceed 5,000 per 100 
ml as a monthly-average value (either MPN or MF count)." This places 
the Muncie Mall and Marhoefer Packing Company as much as 220 times 
the violation figure at times. 

The Prairie Creek Reservoir swimming facility was found to have 
an MPN of 15,000 per 100 ml. A creek, which drains a feedlot 1% miles 
upstream, empties approximately one block from the swimming site. 
This sloping feedlot is located near the corner of 700E and 500S and 
multiplies the coliform group level of the stream 30 times. 

Data cannot relay the offensiveness of the Nebo Bridge outflow 
which dribbles toilet paper down the bank and into White River. Al- 
though residential outflows such as this one are small they are often 
the most potent as all samples having an MPN of greater than 
1,100,000 per 100 ml would indicate. 

The local Stream Pollution Control Board held hearings for the 
Muncie Mall and Marhoefer Packing Company reaching solutions agreed 
to by both parties. The Nebo Bridge outflow and the feedlot were outside 
the sanitary district's jurisdiction but will fall under county health laws. 
There are 123 outflows remaining to be investigated. 



The Effects of Glucose, Acetate, and Malonate Upon Fatty 
Acid Distribution in Aspergillus niger. 

David L. Peterson and Alice S. Bennett, 

Department of Biology, 

Ball State University, Muncie, Indiana 47306 

Abstract 

Submerged cultures of Aspergillus niger were grown In media containing 

different concentrations of glucose, sodium acetate, or sodium malonate. Varying 

concentrations of glucose with or without added acetate did not alter the distribution of 
fatty acids produced by 120 hour cultures. 

Increasing the concentrations of sodium acetate in the 5 per cent glucose medium 
caused the percentage of saturated fatty acids to increase from 20 per cent to 68 per cent. 
However, aerated stir cultures containing 2.5 per cent acetate produced the normal 
amount of unsaturated fatty acids with linolenic acid representing the largest com- 
ponent. In the control cultures linoleic is the major unsaturated fatty acid. 

The high acetate cultures also differed from the control in that their growth was 
markedly inhibited, and the sharp decrease in pH which is characteristic of 
Aspergillus cultures was not observed. 

Similar but not as pronounced effects were observed when sodium malonate was added 
to the 5 per cent glucose medium. 



Introduction 

Research in recent years has indicated that there are at least two 
pathways for the biosynthesis of fatty acids. The acetyl-coenzyme A 
pathway has been observed in intact mitochondria isolated from plants 
(1, 2, 3, 8, 13, 19, 21) and mammals (6, 7, 18). The malonyl-coenzyme A 
pathway, which occurs outside of the mitochondria, has been identified in 
many plant and animal tissues (20, 21). In soybeans (9), isolated plant 
leaves (10), and yeast (5) the long chain fatty saturated fatty acids 
are subsequently converted to unsaturated fatty acids by an oxygen 
dependent enzyme system. 

Members of the Class Ascomycetes, with fatty acid compositions 
similar to those found in higher plants (15), have been used to study 
the biosynthesis of fatty acids in plants and plant-like organisms 
(4, 11, 17). Matto (12) reported that fatty acid synthesis in 
Aspergillus niger was reduced but not completely inhibited when 
avidin, a biotin inhibitor, was added to the medium, suggesting that 
fatty acids are synthesized by a pathway other than that using 
malonyl-coenzyme A. If the alternate pathway utilizes acetate, it should 
be possible to stimulate fatty acid synthesis by this pathway by in- 
creasing the amounts of acetate in the presence of a carbohydrate source 
in the medium. However, Romano and Romberg (14) have reported 
that cultures of Aspergillus nidulans grown in a medium containing 
100 mM of sodium acetate and 100 mM of glucose were markedly 
inhibited in growth and their ability to incorporate hexoses. The fatty 
acid distribution of the inhibited cultures was not reported.

Microbiology and Molecular Biology 263 

In this study the effects of adding increasing amounts of sodium 
acetate and sodium malonate to the culture medium of Aspergillus 
niger were investigated. 

Experimental Procedure 

Aspergillus niger (LBa 376) was maintained on potato dextrose 
agar slants. Spores were lightly scraped and washed from the slants 
with sterile medium. One ml of the spore suspension was used to 
inoculate 100 ml of sterile culture medium. One set of experiments used 
a medium containing from to 5 g glucose and 0.2 g 
KH 2 P0 4 ; 0.2 g MgS0 4 .7H 2 0; 0.2 g NH 4 N0 3 ; 5 g NaC 2 H 3 2 ; and 
100 ml H 2 0. In another, the medium contained 5 g glucose, 0.2 g NH 4 N0 3 ; 
0.2 g KH 2 P0 4 ; 0.05 g MgS0 4 ; 100 ml H 2 and from to 15 g of 
acetate or malonate. Control cultures contained no acetate or malonate. 
Cultures were incubated for 120 hours on a reciprocating shaker (180 
revolutions per minute). Stir cultures were aerated and stirred for 120 
hours. Cultures used for time studies were stirred and aerated in 600 ml 
of medium in a 11 flask. 

At the end of the incubation period or at selected time points the 
mycelium was harvested by filtration through glass wool, resuspended 
in 15 ml absolute methanol, and sonified for 3 min (J-17A Sonifier, 
Branson Sonic Co.). The sonicate was diluted with an equal volume of 
15% methanoic KOH, refluxed for 2 hours, and acidifed with concentrat- 
ed HC1. The fatty acids were extracted with hexane, washed with distilled 
water, and filtered through anhydrous sodium sulfate. After removing 
the solvent on a rotary evaporator, the fatty acids were methylated with 
diazomethane (14). The methyl esters were isolated on silica gel G thin 
layer chromotography plates, and separated, identified, and quantified by 
gas liquid chromatography using a 10-foot glass column packed with 
5% DEGA on 60/80 mesh chrom GA/W; column temperature, 190°C; 
gas flow, 70 ml/min (Varian Aerograph 90-P). 

Results and Discussion 

Although Woodbine et al. (21) reported that the addition of increas- 
ing amounts of carbohydrates to the medium stimulated total fatty acid 
synthesis in Aspergillus niger, our results indicated that increasing the 
amount of glucose in the presence of 5% acetate did not affect fatty acid 
distribution in 120-hour cultures (Fig. 1). 

The normal decrease in pH observed in cultures grown without 
acetate did not occur in cultures grown in a medium containing 
5% glucose and 2.5% or 5% sodium acetate. Growth of the 
mycelium was markedly inhibited at these concentrations and completely 
inhibited at 15%. Romano and Kornberg (14) reported that the uptake 
of glucose in cultures grown in a medium with 100 mM acetate 
decreases as much as 80%. They suggested that acetyl-coenzyme A was 
responsible for the inhibition of hexose uptake. Apparently the acetate 
also inhibits the secretion of citric and gluconic acids which is 
characteristic of normal cultures.

The per cent saturated fatty acids produced by shake cultures grown 
in a medium containing 2.5% sodium acetate was 48% higher than that 
produced by control cultures (Fig. 2). A similar, but smaller (16%) 
increase was effected by the addition of sodium malonate. This effect 
could be reversed by stirring and aerating high acetate cultures 
(Table 1). Upon aeration the percentage of unsaturated fatty acids in 
the acetate culture was similar to the control. 

However, when acetate was included in the medium, linolenic acid 
represented the largest component while linoleic acid was highest in 
the control (Table 2). Whether this difference in the distribution of un- 
saturated fatty acids was due to the increased availability of the 
acetate or the decreased availability of the glucose is not clear.

20390. Experiments which study changes of electronic properties with 

variation in interatomic spacing are critical in their support of energy 
band calculations. The research reported here involves the first observa- 
tion of cyclotron resonance and Alfven wave propagation in Bismuth under 
pressures to 3 kilobars (Rev. Sci. Instr. 42:1215). The experiments are 
carried out at a temperature of 4°Kelvin using a standard 35 GHz bridge 
circuit. Effective mass decreases of the order of 6 per cent per kilobar are 
observed. 

Photoelectric Photometry of an Eclipsing Binary Star System. Ronald 
Kaitchuck and Newton G. Sprague, Department of Physics, Ball State 

University, Muncie, Indiana 47306. Many of the stars comprising our 

galaxy are members of a system of two stars in orbit about each other. 
The vast majority of these systems are far enough from the earth so as 
to appear only as a single point of light even in the largest of telescopes. 
However, if the orbital plane is seen edge-wise by an observer on the earth, 
during some portion of the orbital period an eclipse of one component will 
cause a drop in the observed light output. 

The eclipsing binary system V566 Ophiuchi was studied in detail dur- 
ing the summer of 1971. Data were collected with a photoelectric photo- 
meter and the 12-inch Cassegrain telescope of the Ball State University 
Observatory. A complete light curve was obtained in two different spectral 
regions. The observations indicate that some event during the last 5 years 
has caused a change in the orbital period. There is also some indication 
that the color of the system is not as stable as was previously observed. 
It is hoped that the light curve will yield information as to the orbital 
elements. Standardization of the photometer system should yield the 
surface temperatures of the two stars. 

Neutron Activation Cross Sections Using 2.8 MeV Neutrons. DwiGHT 

E. Michael and Leon M. Reynolds, Department of Physics, Ball State 

University, Muncie, Indiana 47306. A low-voltage type neutron 

generator-accelerator producing 2.8 MeV neutrons has been used to study 
neutron activation cross sections in a number of elements. There is a 
scarcity of good data in the literature because of the generally small values 
of these cross sections and special methods are required to increase the 
number of reactions occurring.

A relative measure of the neutron flux was made using indium 
standards. The efficiency of the detection system was experimentally 
measured by the use of standardized radioisotopes. 

The product isotopes, produced by (n,y) or (n,n'y) reactions, and 
their measured activation cross section were: H6mi n _ iQ4 ± 5mb; 137m Ba 
- 459 ± 45 mb; 139 Ba - 5.48 ± 0.47 mb; 128 I - 38.5 ± 3.0 mb; 56 Mn - 4.28

The Numerical Lathe Fabrication and Theoretical Evaluation of an 
Electron Lens. John Swez and James Westgard, Department of

Plew, Quality Evaluation Section, Crane Naval Ammunition Depot, 

Crane, Indiana. The construction of an electron lens similar to that 

reported by A. V. Crewe (Quart. Rev. Biophys. 3:145) was 
attempted utilizing a numerical lathe. A computer program (APTURN) 
developed by the Cincinnati Research Corporation and used to 
generate control tapes for numerical lathes was modified to accept the 
equation used to generate the nonspherical surface of the lens. Although 
the optical properties of such a lens have been evaluated by A. N. Butler 
(Proc. 6th Int. Congr. for E. M., 1966), a partial evaluation of the optical 
properties was reported here. Computer calculated parameters were dis- 
played on an oscilloscope interfaced to a PDP 8/1 Computer. 

Tayex: A Taylor Expansion Equation Solver. James B. Westgard and 
David G. Pitts, Department of Physics, Indiana State University, Terre

implement a method of solving nonlinear simultaneous differential equa- 
tions. The method was based on the Taylor expansion with an algorithm 
for finding the coefficients. It is extremely easy to use so that it should 
be useful in giving students confidence in being able to handle differential 
equations as they appear in course work. It will be especially useful for 
Lagrangian mechanics. 

D-17B Minuteman Missile Computer Interfacing. C. T. Wunker and

Indiana 47306. Ball State University has recently acquired via govern- 
ment excess property a type D-17B Minuteman missile guidance control 
computer. Hundreds of these mini-computers are being made available 
to colleges and universities throughout the United States. These com- 
puters, as received from the government, do not have usable input and 
output interfacing. To be useful as a teaching or research computer, inter- 
facing must be designed and constructed. The computers and the inter- 
facing now in use at Ball State University were described.

alkali carbonate with Nb 2 f) . The compounds were melted and single 
crystals were pulled from the melt. Many experimental problems such

as phase separation of the melt and cracking of the crystal on cooling 
through its Curie temperature arose in our study. Our solution to these

A Critical Study of the Various Factors Limiting Resolution in Solid 
State Detectors. K. E. Wright and C. C. Sartain, Department of 
Physics, Indiana State University, Terre Haute, Indiana 47809. — — A 
measurement of the intrinsic Fano factor for a particular Si (Li) detector 
was necessary to compare with theory. The Fano factor is defined as 
< (N-N) 2 > = F N, where N, (N) is the (average) number of produced 
ionized pairs; N =E/ C , where E is the initial energy of the ionizing 
particle. The value of the intrinsic Fano factor was determined from the 
relation y 2 = y 2 + y 2 « + y 2 : and by linear extrapolation of 

' ' ion ' col noise 

y 2 for the infinite field strength from the dependence of y 2 on the re- 
ciprocal detector voltage. This measured value of the intrinsic Fano 
factor will ultimately determine whether or not carbon x-rays (277 ev) 
can be detected. The Si (Li) detector will provide chemical analysis 
composition when coupled to an scanning electron microscope. 

Calculus Without Differentials. Phillip S. Marcus, Department of 
Mathematics, Indiana University at South Bend, South Bend, Indiana. 
The differential notation of Leibniz has recently been superceded in popu-

LaGrange, and the abstract operator D notation of Cauchy. Leibniz differ- 
entials are still used in integral calculus. Karl Menger showed that 
differentials can be replaced by the unbelievably simple device of giving 
an explicit symbol — j — to the identity function. Examples were given of 
definite and indefinite integrals and seperable differentiate equations 
which were usually integrated by manipulation of differentials, but the 
usual manipulation of differentials was replaced by Menger's improved 
notation for substitution of functions.

Neutron Activation Analysis of a Metal Button from the Site of Fort 
Harrison. Torsten K. E. Alvager and Ralph A. Llewellyn, Depart- 
ment of Physics, and Robert E. Pace, Department of Anthropology, 

Indiana State University, Terre Haute, Indiana 47809. Among the 

artifacts recovered by the archeologists from the apparent site of the 
Fort Harrison Cemetery were 7 metal buttons. Severe corrosion had 
destroyed those features that might otherwise reveal unit, rank, and date 
of manufacture. With the view of searching old metal specification 
records, the metallic composition of the best preserved of the buttons was 
examined by the non-destructive technique of neutron activation analysis. 
Preliminary analysis using the ISU 2-curie Pu-Be neutron source indicated 
that more complete examination would be of interest. The detailed analysis 
was performed by irradiating the button for 48 hours in the General 
Atomics 10-curie Pu-Be neutron source in San Diego, California. Follow- 
ing irradiation, the gamma-ray activity produced was analyzed using a 
36 cc Ge (Li) detector and a 4096 channel analyzer.

On the basis of the observed gamma-ray energies, the elements posi- 
tively identified as being present in the button are: Cu, Zn, Au, and As. 
It is estimated that copper makes up 89 per cent of the button, zinc and 
arsenic a few per cent each, and gold less than 1 per cent. What appear 
to be gold flecks are visible on the surface of the button, indicating that 
the gold may have been used as a plating or gilting. The button seems 
to be constructed in layers with zinc overlying a copper base. This observa- 
tion together with the relatively higher copper content indicates the 
button was probably not made of alloyed copper and zinc (brass). Tests 
are currently underway using an electron microprobe to "map" the distri- 
bution of metals in the button in order to obtain additional composition 
details. 

The presence of arsenic is not particularly surprising, but the rela- 
tively large amount, perhaps as much as 5-7 per cent, is. Arsenic occurs 
with copper in some ores, and it may be that the high arsenic percentage 
could serve to identify either the source of the ore or the refining 
process. While no investigation along these lines has as yet been started, 
a preliminary search of old metal specification records has been con- 
ducted. Unfortunately, no satisfactorily close match has been found; 
thus, at this writing we are not able to positively identify the button an- 
alyzed as being associated with Fort Harrison. However, the examina- 
tion is continuing and may lead to additional results later.

A Study of the Rate of Absorption of Methylated Mercury by 
Carassius auratus

Terre Haute, Indiana 47809 

Abstract 

Radioactive tracer techniques were used in determination of the rate of 
absorption of a methyl mercury compound by goldfish. Goldfish were retained for 
specified times in test concentrations of CH 3 HgCl containing commercially- 
prepared 7-active Hg 203 . It was found that the fish concentrated the mercury by a 
factor of 2 x 10 2 in the 36-48 hours required for saturation. 

Introduction 

The problem of mercury poisoning has recently been one of intense 
interest in the United States and other countries (1, 2). The degree of 
contamination, the biological effects, the allowable safe amounts in our 
waters, the methods of contamination, and many other questions per- 
taining to mercury and its compounds remain, at best, only partially 
answered. This paper is primarily concerned with the rate at which a 
particular mercury compound is absorbed by goldfish at various concen- 
trations. 

Monomethyl mercury was used because of its solubility in water and 
because it is the generally accepted compound produced by anaerobic 
bacteria in river and lake bottoms (4). 

Measurement 

Known concentrations of the CH 3 HgCl with y-active Hg 203 was 
used as a radioisotope tracer. This isotope was chosen because the y- 
emitted could be easily detected without destroying the fish. To keep the 
fish alive during the time required to measure the y-activity (a few min- 
utes), the fish were placed in a container of fresh running water. 

The detector arrangement was calibrated and adjusted using a pulse 
height analyzer. The initial adjustments were made with gamma rays 
from a Cs 137 source to obtain a suitable energy calibration. The intensity 
calibration was accomplished using a known quantity of Cs 137 and Na 22 
and a scaler counter. Several different levels of contamination were 
investigated. These were 5 ppb, 50 ppb and 500 ppb. Six fish were placed 
in each container. 

Results 

The curves shown in Figure 1 is of the form C = C M (l-e~Xt), where 
C is the concentration, C M is the maximum concentration achieved and 
A is a factor related to the rate of absorption. For the 5 ppb sample 

271 



272 



Indiana Academy of Science 



C M = 0.73 ppm and A — 0.96 hi- 1 and for the 50 ppb sample C M = 6.9 ppm 
and A = 0.108 hr- 1 . With these fits, one half of the final concentration 
is reached in only 7.2 hours and 6.4 hours for the 5 ppb and 50 ppb con- 
centrations, respectively. In addition to the absorption rate found, it was 
discovered that on two different occasions a concentration of 500 ppb 
produced 100% fatality in that particular group of fish within 24 hours. 

A study of the rate of de-absorption was also attempted but was not 
completed. The reason we did not complete this study was that our Hg 203 
with a 47-day half -life decayed so rapidly that meaningful numbers could 
not be obtained. A reasonable assumption for the biological half-life in 
fish is 500 days during normal activity (3). The only conclusion we could 
draw was that the rate of de-absorption was much greater than the rate 
of decay of Hg203.

The Computerization of the Edward Lee Greene Herbarium (NDG) at 
Notre Dame. Theodore J. Crovello, Department of Biology, University 
of Notre Dame, Notre Dame, Indiana 46556. — Edward Lee Greene 
(1843-1915) is a fascinating and important figure in American botany. 
Throughout his career he was an active field botanist and named over 
4,400 genera, species and subspecies new to science. The University of 
Notre Dame possesses his herbarium of 70,000 specimens. Label and other 
data are being captured on punched paper tape and input into a computer. 
The procedures, biological value and types of output being produced were 
discussed. Because Greene left no collection notebooks, it is only from a 
computerized rearrangement of his specimen label data that his itinerary 
can be obtained. Also, he often did not indicate which specimens were type 
specimens. The specimen data and the data on what species he named can 
be used to pinpoint some type specimens and to generate a list of missing 
type specimens. The computer is seen as a valuable tool in assisting the 
taxonomist in his information retrieval problems and as a means to 
enhance the value of this Indiana resource. 

The Origin of Seed Planting. Charles B. Heiser, Jr., Department of 

Botany, Indiana University, Bloomington 47401. Recent archaeological 

investigations have revealed a great deal about the origin of agriculture, 
but the question as to why man ever changed his mode of subsistence 
remains unanswered. A religious motive has been suggested for the origin 
of animal domestication, and in a little known paper published in 1897 
Grant Allen postulated that the sowing of seeds for crops began as an 
adjunct to the primitive burial system. While Allen's proposal has some 
merit, I am more inclined to look for the origin of seed planting as a con- 
sequence of the "first fruits" or "last sheaf" ceremonies of primitive seed 
collectors. Primitive man believed that spirits existed in plants and as 
a propitiation to the spirit the first fruits were returned to the fields. This 
magico-religious act would make the seeds safe for mortals to eat and 
at the same time assure a beautiful harvest in future seasons. Such a 
hypothesis would also offer a possible explanation for the rapid improve- 
ment of the early cultivated plants, in that man would return some of the 
best seeds to the field instead of eating them. Thus one might postulate 
that artificial selection began to operate with the offering of seeds to the 
spirits of the plants.

A Biosystematic Study of Polygonum ramosissimum and 
Polygonum tenue 1 

George M. Brooks and Thomas R. Mertens 

Department of Biology 

Ball State University, Muncie, Indiana 47306 

Abstract 

Plants collected in Wisconsin during September 1970 were identified as 
Polygonum ramosissimum and P. tenue according to the taxonomic character established 
by Styles for European species of genus Polygonum and adapted for North 
American species of this genus by Mertens and Raven. The somatic chromosome numbers 
for these two species were determined to be 60 for P. ramosissimum and 30 or 32 for P. 
tenue. These counts were compared with chromosome numbers of species of section 
Polygonum, all of which have a somatic number of either 40 or 60. Chromatographic 
analysis of free amino acids and secondary substances further suggests that 
P. ramosissimum has amino acids similar to those of other species in section 
Polygonum. Chromatographic data for P. tenue is somewhat less conclusive in assigning 
this species to a section of genus Polygonum. 

Genus Polygonum, section Polygonum (Avicularia) consists of a 
number of morphologically similar plant species. Individuals within each 
species vary morphologically according to local edaphic and climatological 
conditions. This has led to a general confusion among taxonomists who 
have been attempting to identify field and herbarium specimens, on the 
one hand, and to systematists, on the other, who have been attempting 
to assign natural rank to the various species of Polygonum. This study 
reports on an attempt to establish the natural relationships of two Poly- 
gonum species to section Polygonum by using cytological and chemical 
parameters. 

Research in the 1960's brought taxonomic clarification to some 
species within section Polygonum. Styles (9) defined the four species of 
the Polygonum aviculare aggregate found in Britain (P. aviculare, P. 
arenastrum, P. rurivagum,, and P. boreale) , and three other species found 
elsewhere in Europe (P. maritimum, P. rati, and P. oxyspermum) in terms 
of fruit and perianth characteristics and chromosome number. He found 
achene texture, color, shape and size, and inflorescence position to be 
stable and conservative traits. Mertens and Raven (5), using the bio- 
systematic approach of Styles (9), studied the P. aviculare complex in 
North America and were able to devise a workable key for eight species 
of section Polygonum. Savage and Mertens (7) studied six species of 
Polygonum found in Indiana and Wisconsin by using the parameters 
established by Styles. Moore, Mertens, and Highwood (6) summarized 
cytotaxonomic data on various species within this same section. These 
workers compared chromosome number with the taxonomic characters 
decided upon by Styles and later researchers, to determine if indeed a 
plant with a certain combination of fruit and perianth characteristics 
consistently displayed the same chromosome count.

The present investigation is concerned with examining Polygonum 
ramosissimum and P. tenue to determine if they are to be included in 
section Polygonum. The two species, collected in Wisconsin, were keyed 
according to the following taxonomic couplet established by Savage and 

Mertens (7) : 

Achene surface predominantly smooth and shiny but may have stip- 
pled or striated edges; inflorescences appear to be terminal, the 
flowers being more-or-less clustered at the ends of stems among 
reduced leaves or bracts; perianth tightly oppressed to the achene, 
which has three equal concave sides. 

Achene surface completely smooth, achenes dark reddish brown, 
sharp angled; calyx yellowish green, plant large [3-10 dm], 
much branched P. ramossissimiim 

Each face of black, trigonous achene smooth and shiny but 
bordered with striated or stippled margin; plant slender 
[1-4 dm], stiff or wiry; leaves linear ..... F. tenue 

Materials and Methods 

All plant material was collected in Wisconsin at two sites along the 
Wisconsin River on September 27, 1970. Both species were collected In 
a sandy beach habitat. Polygonum ramosissimum was found 2M miles 
due west of Lone Rock in Richland Co., Wisconsin. Polygonum tenue was 
gathered in Upham Woods in Juneau Co., Wisconsin. 

Viable achenes were removed from the plants and germinated on 
moist filter paper in petri dishes. Chromosome coonts were made of root 
tip and apical meristem cells treated with the mitotic poison, oxyquinoline, 
and stained with aceto-orcein. 

Chromatographic patterns of the two plants under study were com- 
pared with patterns made by other species of Polygonum, section Poly- 
gonum. Single dimensional paper chromatograms testing for the qualita- 
tive distribution of free amino acids and secondary substances among 
the compared plants were run to see if a related pattern developed. It was 
assumed that related species would have similar,, but not necessarily 
identical, chromatographic patterns, and that different plants of the same 
species would consistently display the same patterns. 

A mixture of 0.3 g of plant root, steam, and leaves was pulverized in 
a motar and then transferred to a vial with 2 ml of 80% methanol. 
After a drop of 1 N hydrochloric acid was added, the vial was corked and 
allowed to stand at room temperature for 24-48 hours before the extract 
was used to streak the chromatography paper. 

Single dimensional chromatograms were developed by the descending 
method using 46 X 57 cm Whatman No. 1 chromatographic paper. The 
plant extracts were applied to the paper with a 10-^1 pipet. Generally 100 
fil of plant extract were needed to get readable results. The chromatograms 
were developed for 24 hours, using a solvent mixture, described by Smith 
(8), consisting of 12 parts n-butyl alcohol, 3 parts glacial acetic acid, and 
5 parts distilled water.

The chromatograms in which the free amino acids were to be detected 
were sprayed with a ninhydrin aerosol bomb. The chromatograms were 
dried in the dark for 24 hours before observations were made. Secondary 
substances were detected by placing unsprayed chromatograms under 
long-wave ultraviolet light in the presence of ammonia vapors. 

Data 

Definite chromosome counts were obtained for Polygonum ramosissi- 
mum from these plants:

P. ramosissimum Michx., Richland Co., Wisconsin, Sept. 27, 1970, 
G.M. Brooks No. 75 (BSU). Somatic count of 60. 

Photographs of the chromosomes found in cells of these two plants were 
taken (Fig. 1). Diagramatic line drawings of the cells counted were made 
because all chromosomes do not appear equally well at the focal level from 
which the photomicrographs were taken (Fig. 2).

A single dimensional paper chromatogram was developed for P. avicu- 
lare, P. erectum, P. ramosissimum, and P. tenue. It was sprayed with nin- 
hydrin to develop the free amino acids which had migrated down the paper 
from the sites of origin. A second single dimensional chromatogram was 
developed with the same four plants and was placed under long-wave ultra- 
violet light in the presence of ammonia vapors to highlight the secondary 
substances. Table 1 gives the R f values of the qualitative distribution 
of the free amino acids for the four plants; Table 2 shows the same for 
the secondary substances.

Discussion 

Species of genus Polygonum section Polygonum generally give 
somatic chromosome counts of 40 or 60. Styles (9) determined the somatic 
number 40 for P. arenastrum and 60 for P. aviculare, while Mertens 
and Raven (5) determined the somatic number of 60 for P. marinense. 
Love and Love (4) reported that P. erectum and P. fowleri each has a 
somatic number of 40, and these counts have been confirmed by Moore, 
Mertens, and Highwood (6). It may be that the basic chromosome number 
in this group of plants is #=10, and that those species with 40 chromosomes 
are of tetraploid origin, while those with 60 are hexaploids. This suggests 
that P. ramosissimum might also have a somatic chromosome count of 
40 or 60 if it is to be included in section Polygonum. The determination 
that P. ramosissimum indeed does have a somatic count of 60 agrees with 
this cytotaxonomic requirement. Love and Love (4) published a somatic 
chromosome number of 20 for this species collected in Manitoba. However, 
voucher specimens were not kept for cross-checking purposes, thus calling 
their finding to question. 

Polygonum tenue collected for this study had a somatic chromosome 
count of 30 or 32. This departure from a count of 40 or 60 (which numbers 
seem to be generally characteristic of plants in genus Polygonum, section 
Polygonum) may suggest that P. tenue belongs to another section of the 
genus. This would be especially true if the count proves to be 32 rather 
than 30. Love and Love (4) reported this plant to have a somatic count 
of 20. Again, no voucher specimens were kept to verify their findings for 
P. tenue collected in Minnesota. Mertens and Raven (5) commented that 
P. tenue was morphologically similar, from the standpoint of its fruit and 



282 Indiana Academy of Science 

perianth characteristics, to other species of section Polygonum, but that 
this plant had pollen of the type found in section Duravia. 
(2). Thus ? palynological data tend to support the contention that P. tenue 
should be assigned to a section of the genus other than section Polygonum. 

Alston and Irwin (1) were able to separate closely related species 
of the genus Cassia (Caesalpinia Family) by using paper chromatographic 
techniques. Jones and Mertens (3), by using the same technique, were 
able to qualitatively distinguish among a number of species of Polygonum 
section Polygonum. The data in the present investigation (Tables 1 and 
2) show that P. ramosissimum has basically the same qualitative distribu- 
tion ©f amino acids as do the two established species of section Polygonum, 
P. aviculare and P. erectum. 

Although the chromatogram of amino acids for P. tenue indicated 
that this species has many spots in common with the other three species 
studied, certain repeatable differences in the chromatograms were noted: 

1) To obtain a readable chromatogram for P. tenue speci- 
mens, the extract had to be four times as concentrated at the site of origin 
as for any of the other species investigated. 

2) The color intensity of the various chromatogram spots for P. 
tenue was always less than for comparable spots of the other species. 

3) Although the size of the streak of origin of the P. tenue chroma- 
tigram was comparable to that used for the other species, the size of the 
spots in the chromatogram were consistently smaller than comparable 
Poots for the other species. 

It may be argued that the chromatogram of P. tenue differs from 
those of the other three species only in lacking certain spots and that this 
CDuld be due to less diversity in its genome in response to a more restricted 
habitat. However, the three points cited above would seem to argue for 
the uniqueness of the chromatogram of P. tenue. 

Secondary substances are so termed since thay are not involved in 
basic energy transfer or catabolic activity of plant tissues. These com- 
pounds (alkaloids, terpenoids, and polyphenols) are stable by-products 
and so can be used as chemical taxonomic parameters. 

Although certain spots in the chromatograms of secondary substances 
of the different species seem to be identical (e.g., .68 yellow in P. avicu- 
lare and .69 yellow in P. erectum), the overall qualitative distribution of 
secondary substances was unique for each species. This suggests that sec- 
ondary substance analysis may be used to establish speciation, since each 
of the four species studied had a different overall chromatographic 
pattern and various plants within a species displayed a consistent 
pattern. 

Conclusions 

1) Polygonum ramosissimum, with a somatic chromosome count 
of 60, seems to be similar to established species of section Polygonum all 
of which have either 40 or 60 as their somatic chromosome number. 



Plant Taxonomy 283 

2) Since the tentative somatic chromosome counts of 30 or 32 for 
P. tenne were made from collections at one site, and since they do not 
agree with counts reported in the literature, fresh specimens of P. tenue 
containing viable achenes should be collected and a definite chromosome 
number determined. 

3) Chromatographic studies indicate that the overall qualitative 
free amino acid distribution for P. ramosissimum is similar to the distri- 
butions shown by species of Polygonum in section Polygonum. 

4) Polygonum tenue has quite a different overall qualitative amino 
acid distribution due to: a) the greater concentration of extract required 
in order to get readable chromatograms, b) the much weaker color 
intensities for the various spots, and c) the smallness of the spots in 
comparison to comparably colored spots of the three other species at the 
same R f locus on the chromatogram. 

5) The overall quantitative distribution of secondary substances 
is unique for each species with various specimens of the same species 
giving the same pattern.

Abstract 

Two additional species and two additional varieties have been found to occur in 
Indiana since the publication of Studies in Indiana Bryophytes XIII (15): 
Atrichum undulatum (Hedw.) P. Beauv. var. oerstedianum (C. Mull.) Crum; Grimmia 
pulvinata (Hedw.) Smith; Isopterygium distichaceum (Mitt.) Jaeg. & Sauerb.; and 
Pohlia annotina (Hedw.) Lindb. var. loeskei Crum, Steere and Andrews. Specimens of 
each have been deposited in the Herbarium of DePauw University. One species, 
Grimmia indianensis (Sayre) Crum (3), originally G. trichophylla Grev. var- 
indianensis Sayre (12), has now become a synonym of G. pulvinata (Hedw.) Smith. The 
total number of known species of mosses in Indiana is presently 228, varieties 39, and 
forms 9, a total of 276 kinds. 

The American Bryological and Lichenological Society 1970 foray 
was held in West Central Indiana, including- habitats in Putnam and 
Parke Counties. One species, Isopterygium distichaceum (Mitt.) Jaeg. 
& Sauerb., and one variety, Pohlia annotina (Hedw.) Lindb. var. 
loeskei Crum, Steere and Anderson, were collected by two foray 
members, which are first records for Indiana. Another collection is that 
of a species (9) or a variety (4) which has been present in eastern 
United States indefinitely, within the species Atrichum undulatum 
(Hedw.) P. Beauv. A. oerstedianum (C. Mull.) Mitt, was not known 
to occur in the United States until the research on Atrichum published 
by Ireland (9). 

On July 22, 1971, Keith Hoss, an Army Corps Engineer, and I 
visited Rocky Ford, on Big Pine Creek, in Warren Co., Indiana, search- 
ing for Grimmia indianensis (Sayre) Crum, in the area in which I 
collected the type, Nov. 27, 1937. The search was in vain. All of our 
collections were G. alpicola Hedw. The next day Mr. Hoss returned to 
Rocky Ford, crossed Big Pine Creek, on to Mud Pine Creek, a tributary 
to Big Pine, and climbed Table Rock in the creek bed. Table Rock has 
a flat top and steep sides. Mr. Hoss estimated this block of sandstone, 
a remnant of erosion (11) to be ca. 8 feet high, 50 feet long, and 30 feet 
wide, and exposed 6-7 feet above the water in the stream. On the flat top 
surface, there is a pothole, 2 feet deep and 10 feet in diameter. On this 
rock Hoss made several collections of G. pulvinata (Hedw.) Smith, 1 a 



'From a letter from H. A. Crum, Oct. 22, 1971: "I am convinced that Grimmia 
indianensis is a synonym of G. pulvinata. I would perhaps never have thought of it, 
except for the several collections you recently sent from Warren County and the type 
locality. It appears that both typical G. pulvinata and typical G. indianensis grow in 
the same locality, the latter probably no more than a shaded expression with less ob- 
viously contorted leaves and a poor development of hairpoints on the leaves. (I have 
seen a similar development from Scotland.) The specimen which you sent could be 
called G. indianensis, but it merges in its variations almost completely into typical 
G. pidvinata."

Hypnaceae 

Welch (14) considers the genus Plagiothecium B.S.G. in the family 
of Hypnaceae. Crum et al. (5) regard Plagiothecium as a genus in the 
family of Plagiotheciaceae. Ireland (10) in his revision of the genus 
Plagiothecium treated it as a genus in the Hypnaceae. 

According to Ireland (10), the Indiana species in Welch (14) should 
be revised as follows. Plagiothecium denticulatum (Hedw.) B.S.G. and 
P. roesanum B.S.G. are correct; P. micans (Sw.) Paris = Isop-

Polytrichaceae 

Atrichum undulatum (Hedw.) P. Beauv. var. oerstedianum (C, 
Mull.) Crum. Atrichum undulatum in Indiana was described and illus- 
trated by Welch (14), based on collections from 50 counties. Ireland (9) 
states that most of the eastern North American specimens of 
Atrichum in the herbarium of the Museum of Natural Science, 
National Museums of Canada named A. undulatum are A. 
oerstedianum (C. Mull.) Mitt, and that A, undulatum is not as common 
as once believed. 

The following is a brief summary of Ireland's description. Plants 
2-6 cm high. Dry leaves usually undulate, twisted and crispate, 
lingulate to lanceolate, 5-9 X 0.8-1.6 mm, acute, ending in a tooth. 
Margins bordered ± throughout with 2-3 rows of narrow, linear, 
thick-walled cells, the border usually bistratose; upper margins 
toothed, singly or doubly. Costa subpercurrent to percurrent, toothed 
on lower surface from midleaf to apex, lamellae on upper surface. 
Lamellae 4-6, often undulate, 2-4 cells high, occasionally 6. Leaf cells 
smooth or minutely papillose. Median cells rounded or irregularly

angled, 12-31^, in longest dimension, averaging less than 17^ 
in shortest dimension. Calyptra hispid at tip. Dioecious. Seta 1.5-4 cm 
long, 1-3 per perichaetium. Capsule cylindric, usually inclined and 
subarcuate. Urn 4-7 mm long. Operculum obliquely rostrate, 2-3.5 mm 
long. Spores 12-17^ in longest dimension. 

Ireland states that A. oerstedianum is our native species and one 
of the common species in eastern North America and that A. 
undulatum has been introduced, probably from Europe, and rarely 
collected on this continent. Ireland adds that the latter prefers a dry, 
weedy habitat, such as weedy roadside ditches and the former occurs 
in wet habitats, especially on humus and soil along stream banks and 
inundated areas. 

Crum (4) reduces this species to the synonymy of Atrichum 
undulatum and makes the var. oerstedianum (C. Mull.) Crum. He 
states, "Without sex organs or capsules, the var. undulatum and the 
var. oerstedianum are impossible to distinguish (except sometimes by 
size and habitat)." The var. undulatum, at least in some plants, is 
monoecious, and the var. oerstedianum is dioecious. 

Habitat: On soil or humus, mostly in shaded situations; often in 
wet areas along streams or occasionally at margins of swamps.

The Effects of Preservation Time on 
Chromatographic Patterns in Equisetum hiemale 

Larry C. Brown 

Department of Biology

Abstract 

A study was made to determine if the age of a herbarium specimen of 
Equisetum hiemale L. had any effect on the chromatographic patterns. Specimens of 
E. hiemale were analyzed employing descending paper chromatography. The amino acid 
and phenolic patterns were of significant value in determining if the chromatographic 
patterns varied as the herbarium specimen aged. The fluorescent phenolic compounds of 
E. hiemale were analyzed by placing the chromatograms under long wave ultraviolet light. 
The free amino acids were detected by spraying the chromatograms with ninhydrin. 

The chromatographic patterns showed that the age of the oldest herbarium specimen 
investigated had no effect on its patterns. 

The purpose of this study was to determine if variations occur in 
the free-amino acid and phenolic chromatographic patterns of 
Equisetum hiemale L. samples taken from herbarium specimens as com- 
pared with those obtained from fresh material. 

Since the technique of paper chromatography appeared, it has 
contributed significantly to systematic studies (3). The works of 
Alston and Irwin, Heywood, Smith and Levin, and others have firmly 
established the study of "secondary constituents" as a valid taxonomic 
method (1,4,7). 

Analyses can be carried out on fresh plants from the field, or 
greenhouse transplants. In the absence of fresh material, the inves- 
tigator may have to resort to using herbarium specimens. Since some 
taxa are exceedingly rare, and some are difficult to grow under 
greenhouse conditions, it is significant to know whether detectable 
differences exist between freshly-dried specimens and ones which have 
been dried for long periods of time. Some workers have stated that no 
significant differences exist (7). Others suggest that analyses are best 
carried out on fresh materials (6). 

Methods and Materials 

Herbarium specimens of Equisetum hiemale were obtained from 
the Missouri Botanical Garden Herbarium and the Field Museum of 
Natural History. Those materials had been preserved for periods up 
to 144 years. Fresh material was collected in Richmond, Indiana. 

Comparisons of free-amino acid and phenolic composition were 
made by means of 1-dimensional paper chromatography. Extracts were 
prepared by powdering dried internodes and soaking the materials in 
methanol :water:hydrochloric acid (7.9 : 2 :0.1) for 24 hours at room 
temperature. One hundred microliters of each sample were applied to 
23 X 57 cm sheets of Whatman #1 paper using the spot 
method. The chromatograms were run using n-butanol: acetic acid: 
water (12 : 3 : 5) as the solvent. Following air drying at room 

290

291 



temperature, the chromatograms were viewed under long wave ultra- 
violet light in the presence of ammonia vapor. Those spots which 
fluoresced but did not show a ninhydrin reaction were taken to 
represent phenolics (1, 2, 5). Subsequently the chromatograms 
were sprayed with ninhydrin for the detection of free-amino acids and 
related substances (1, 2, 4, 5, 7). 

Results 

The chromatographic results of horsetails which had been preserved 
for periods of time ranging from four to 144 years were compared 
chromatographically with freshly collected materials (Table 1).

Comments on a Check List of Indiana Algae: Purpose and 
Problems 

Fay Kenoyer Daily

Butler University, Box 169, Indianapolis, Indiana 

Abstract 

A check list of Indiana algae by county has been compiled from the literature 
appearing from 1929 to 1971. This is the fifth in a series of publications initiated by 
C. M. Palmer who covered the algal reports of 1875 to 1928. A few additions to this 
period have been made. The purpose of the check list and some problems in its use and 
preparation are discussed. 

In 1929, C. M. Palmer (1) provided a check list of Indiana 
algae based upon his own research and publications appearing from 
1875 to 1928. Additions were included in three later papers (2, 3, 
4). Distribution maps for each taxon were filed at Butler University. 
When Dr. Palmer moved to Ohio in 1950, the work was continued by 
the present author and William A. Daily. The first check list since then 
covering the 1929 to 1971 period has been compiled and will be 
distributed by the author upon request. 

In the interest of continuity, algae are listed essentially in the same 
style as that used by Palmer except for literature citations. The 
genus, species and infraspecific names are followed by the county where 
the algae were found and with the literature citation in 
parenthesis (Table 1).

The purpose of this work is to inventory the algae occurring in the 
state and to give distribution by county. This information is useful as 
an historical document and may help relocate specimens in herbaria 
or in nature. The latter is possible because some algae may persist in 
the same or nearby habitats for many years. The interest in 
geographical occurrence anticipates possible reflected ecological 
patterns. A. C. Smith (5) summed up the value of systematics as 
follows: "Agriculture, medicine and all phases of human economy 
ultimately depend upon natural living organisms of which no real 
understanding can be had without a basic inventory and knowledge of 
spatial and environmental relationships." 

Nomenclature in the check list is the same as in the literature 
cited. This was necessary because specimens are not available as a 
basis for all reports. This precludes restudy to produce a uniform, 

294 



Plant Taxonomy 295 

modern classification. There is also a lack of agreement on the classifi- 
cation of many algae. Herbarium specimens are not available, in part, 
because of the following differing concepts or methods in taxonomy. 

Specimens preserved by drying and storing in an herbarium are 
sometimes criticized as worthless, so none were kept by the authors. 
Others prepared liquid-preserved specimens which have dried and 
have been discarded. However, some taxonomists have studied the 
effects on algal morphology of varying conditions of the habitat, 
differing methods of collecting, handling and restoring specimens, 
and can recognize most algae from well-preserved dried specimens 
demonstrating the necessary stages for identification. This ability is 
necessary for a monographer employing the type method or in applied 
microscopy. 

Various techniques have been applied to algal taxonomy during 
the 1929 to 1971 period. These include the study of cultured algae, 
the use of scanning and electron microscopes and various advances 
in genetics, physiology and biochemistry. Many of these studies have 
made substantial contributions. 

However, some methods require cultured algae free of con- 
taminating organisms, and only cultures are cited. It has been found 
that algal morphology is sometimes different after isolation in 
artificial media. It has been suggested that this may be due to 
genetic changes induced by shock of isolation or unnatural growing 
conditions, undetected contamination by a second alga which may 
become dominant later, the mixed genetic constitution of the original 
isolate or other undetermined factors. If the mechanisms of inheritance 
and genetics have not been compared in cultured algae and 
natural populations, genetic studies based on cultured algae alone may 
result in classification without general application due to the above 
difficulties. 

On the other hand, algal morphology may be very uniform under 
the cultural conditions employed. Results from the study of a few of 
these specimens may not reveal the wide range of morphological 
variation that is apparent in a study of a large number of 
specimens from nature under varying habitat conditions. 

It is, therefore, recommended that herbarium specimens of natural 
collections (or soil collections, if applicable) be prepared as a basis for all 
algal reports. Comparison of adult forms can be made with cultured 
material to detect morphological change. Resting forms can be 
recultured from soil for comparison. Classification based on culture 
characteristics should indicate the specimens seen by the code of the 
culture collection.

Uses of a Student Responder System. Lloyd L. Bodie, Jr., Plane- 
tarium Director, Vigo County School Corporation, Terre Haute, 

Indiana. Traditionally, educational procedures have required that 

the instructor have a limited maximum number of students within the 
classroom. The Student Response System (SRS) has made it possible 
to bring some of the most important features of the small teaching 
classes to large group instruction. This paper described the use of SRS 
by a qlass of 65 junior and senior students from high schools in Vigo 
County School Corporation, enrolled in Astronomy, at the Allen 
Memorial Planetarium. All students had a science and mathematical 
background. Topics discussed included the strengths and weaknesses 
of this system as used in our program; the description of the 
Responder System— the instructor's console, the student units, and 
the central electronics unit printer; the student's operation of the 
responder system; the value to the student; and some typical questions 
asked. 

An Audio-tutorial* Independent Study Program for the Elementary 
Teacher. Conrad Carlyle Hinds, Department of Education, Ball State 

University, Muncie, Indiana 47306. -The purpose of this study was 

to develop and test an audio-tutorial, independent study program on 
simple machines to meet the individual needs of elementary in-service 
teachers. 

The research was designed to determine how well in-service 
teachers could learn the specific content involved using this particular 
approach. Advantage was taken of the teaching skills and methods 
which teachers employ in their own classes. Pre- and post-tests of the 
Smith Mechanic Test were administered. 

Two samples were drawn from the population of elementary 
teachers in the Science 590 extension and summer classes at Ball State 
University. There was a control group of 29 elementary teachers and 
an experimental group of 48 elementary teachers. The experimental 
group used the audio-tutorial program. The control group received class- 
room instruction over the specific content involved. 

The difference in means between groups was examined for 
significance using a two-tailed t-test. No significant difference was 
found on the pre-test. A significant difference beyond the 0.01 level was 
found on the post-test (t = 2.87, 75 d.f.). Each group was considered 
separately for significance in the mean gain. The control group 
showed significance at the 0.05 level (t = 2.05, 28 d.f.). The 
experimental group showed significance beyond the 0.001 level 
(t = 13.54, 47 d.f.).

It was concluded that the audio-tutorial program afforded a much 
better mode for practice over the specific content involved than did 
classroom instruction. It was recommended that the program be used 
in conjunction with elementary pupils to measure any increase in 
teacher competency more accurately; that the program be used in a 
teaching situation other than the extension class to measure retention; 
that the program be used as one mode of presentation in the Science 
590 classes; and that administrators institute this program into 
schools as part of continuing in-service training. 

Training Supervising Teachers to Evaluate and Counsel Pre-Service 
Teachers on the Basis of Teaching Techniques Derived From Methods 
Courses. Stanley S. Shimer, Linda B. Knight, and Harold H. 
Jaus, Science Teaching Center, Indiana University, Bloomington, 

47401. The Indiana University, Bloomington Campus, Triple "T" 

Program is a professional year internship for pre-service elementary 
teachers which combines student teaching with basic methods courses. 
This program assumes that the techniques taught in methods classes 
are implemented in the classroom. However, it was found that the 
terminology used in the methods class, indeed, even the teaching 
techniques covered in the course were unfamiliar to many of the class- 
room supervising teachers. Thus, there was very little reinforcement 
of the method topics used by student teachers in the classroom. A 
package of instructions was developed for the supervising teachers to 
acquaint them with the topics dealt with in the methods courses and to 
aid them in reaching competency in evaluating a student teacher's use 
of these techniques. This enabled supervising teachers to evaluate and 
counsel the student teachers. It also provided the student teachers with 
much needed reinforcement and feedback on the use of teaching 
techniques. 

The package consisted of 9 hours of performanced-based-instruction 
on techniques selected from the Science Methods Curriculum, e.g., 
performance objectives, question asking skills, formative evaluation, 
teacher responses, systematic instruction and sequencing. Formative 
Post Tests were designed for each unit and summative evaluation was 
administered at the end of the 9 weeks. Data indicated that supervising 
teachers are more able to accurately evaluate and counsel pre-service 
teachers after receiving this package of instruction. 

An Environmental Science Conservation Course. H. Douglas Shock, 

Cowan High School, RR 4, Muncie, Indiana 47304. An environmental 

science conservation course for the high school level was developed to 
give students a basic understanding of their environment, of the en- 
vironmental problems which are facing each of them and to help each 
student discover his role in making the environment a place worth 
living. The writer taught the course for 2 years before formalizing it 
by writing a creative project for the degree of Master of Science at Ball 
State University. To accomplish this, the following study units were 
planned: Life Designs, Conservation in Perspective, Ecology, Popula- 
tions, Soil Resources, Minerals and Energy, Water Resources, Air 



Science Education 299 

Resources, Plant Resources, Animal Resources, Resource Relationships, 
Recreation, Community Planning, and Careers. 

The course was designed to use a wide variety of learning experi- 
ences rather than from a single source, such as a textbook. Books, 
pamphlets, library materials, films, resource people, and field experi- 
ences relative to the course of study were planned to enhance the 
student's awareness of his environment. Group work was encouraged 
throughout the course to help build a willingness for cooperation. 

NOTE 

Reading Habits of Prospective Secondary Earth Science and Geography 
Teachers. William D. Brooks, Department of Geography and 
Geology, Indiana State University, Terre Haute, Indiana 47809.— —At 
Indiana State University, within the Department of Geography and 
Geology and in cooperation with the Division of Teaching, all geography 
and earth science teaching majors are required to take a 2-credit hour 
course entitled "The Teaching of Geography in the Secondary Schools" 
(G393). A methods course, G393 meets 4 days each week for 8 conse- 
cutive weeks. This 8-weeks period represents the first half of the profes- 
sional semester while the second half is spent in a student teaching 
experience under local school and university supervision. 

Juniors and seniors prior to the student teaching experience and 
prior to attaining professional status should be in the process of 
organizing in-depth knowledge not only in a chosen content area but 
also in educational theory and practice. It seems obvious that an upper 
semester junior or senior enrolled in a program leading to professional 
status should have developed or be in the process of developing a 
sophisticated reading habit. 

The purpose of this study was to examine the reading habits of pros- 
pective secondary teachers of geography or earth science. 

To test empirically student reading habits, all students enrolled in 
G393 for six consecutive semesters were asked to submit a one page 
report each week on anything they had read that could in any way be 
related to the teaching of geography or earth science. No other direc- 
tions were given nor were restrictions imposed. Each time the course 
was given a number of class periods were spent examining and dis- 
cussing a variety of sources that could be used to acquire knowledge 
in earth science, geography and education. 

First, a total of 258 reports were submitted which represented 113 
different sources. Twenty-six of the 113 sources were considered pro- 
fessional-educational journals. Thirty-eight books were critiqued, thus 
64 of the 113 sources can be considered excellent sources for acquisition 
of knowledge. 

Second, of the 258 reports 188 were from important journals. Add 
39 book reports (one book reported twice) for a total of 157 reports 
gathered from first-rate information.

Third, 88 reports were gathered from newspapers, layman journals 
(Newsweek, Time, etc.) and government agencies. The rest of the 
reports, 13 in number, were placed in that "catchall" category other.

Abstract 

The System for Ecological Education (SEE) is a new systematic approach to life- 
centered environmental education which employs a scope and sequence format. It includes 
grade level teaching materials for K-6, and for grades 7-12 a scheme of eight topics of 
concern which can be integrated into existing eurriculums. 

SEE provides a unifying framework within which the environmental 
input of all educators may become cumulative. It is ecologically com- 
prehensive and forms the basis for college level teacher training. It es- 
tablishes for K-12 educators minimum ecological understandings for 
each year of study. It suggests a route to take to bring about these 
understandings; yet it allows full latitude for the teacher to exercise 
initiative and imagination. 

Because SEE is a system, it requires teacher direction to assure 
a smooth flow, and this direction may be used to make sure that the 
child becomes a participant in the educational experience. Students are 
expected to learn by doing. The laboratory for learning is their own 
local surrounds. 

Scope and Sequence — Grades 1-6 

The scope and sequence charts, one for each grade, are based on 
environmental concepts developed by Roth (2) ; the U. S. Department 
of Agriculture, Forest Service (3) ; and the Indiana Department of 
Public Instruction (1). There has been substantial grouping of 
material for simplification, and most concepts are presented in 
language appropriate to the grade level in which they are used. The 
concepts selected for each grade are those which are comprehensible 
and which contribute to the progressive grade by grade development 
of the horizontal thought threads. The six threads are: 1) Living 
Things, 2) Needs of Living Things, 3) Meeting Needs and Wants, 4) 
Problems from Meeting Needs and Wants, 5) Solving Problems, and 
6) Man's Moral Responsibility. It is important to understand that in 
these threads the material becomes increasingly more complex in each 
successive grade. Across the time span of the child's education, each 
thread remains intact; and at the completion of high school, building 
is still taking place on the understandings introduced in kindergarten 
or in one of the lower grades.

K-12 Grade and Subject Area Teaching Materials 

Kindergarten 

The system presents 25 pages of material which is divided into 
three subject areas: 1) Using the Senses; 2) Introducing the 
Physical Environment- — Air, Soil, Water, and Sun; and 3) Living 
Things. Included in each area are experiments, outdoor activities, games, 
and a bibliography guiding the teacher to books, films, filmstrips, pic- 
tures, charts, and other visual aids. 

Grades 1-6 

Individual grade level charts have been developed. These expand 
the concepts found on the scope and sequence charts for each 
grade. The expansion sometimes involves more than one sub-concept. 
It employs the same horizontal threads used in the scope and sequence 
chart. Grade level charts are made up of one vertical column for the 
concept or sub-concept and six veritcal columns with the following 
headings: 1) Introducing the Concept; 2) Developing the Concept; 
3) Films, Filmstrips, & Slides; 4) Other Visuals; 5) Publications; 
and 6) Other Resources & Suggestions. 

In many columns of their grade charts, teachers will be guided by 
an asetrisk (*) to refer to a separate guide book. In It 
they will find suggested activities to help develop the concept or written 
material to further their own understanding of the concept. 

Grades 7-12 

The concepts for these grades are presented in four vertical 
columns 1) Title; 2) The Natural Laws (Governing Factors); 3) 
Man Apart from, Nature (Problems Created) ; and 4) Man a Part of 
Nature (Solving Problems) . 

Each of eight topics is treated in every vertical column. The 
study of the first topic, How Many People are Enough?, for 
example, involves consideration of three things in the column entitled 
The Natural Lavjs: 1) Population change is the product of biotic 
potential and environmental resistance. 2) Living things increase in 
number to the level the environment will permit. Man's ability to 
modify the environment does not make him an exception. 3) The 
Earth's carrying capacity is finite for one and all species. 

In the column Man Apart from Nature, students consider the need 
for restrictive laws and regulations which arises as the population in- 
creases. They also find proof that as numbers of people increase, the 
need for food, fiber, and minerals (energy in particular) expands. 

In the column Man a Part of Nature, they give careful 
study to man's obligation to function rationally in a system with his 
culture and the biophysical environment. 

There are seven other subjects covered by this same horizontal 
approach: 1) Consuming the Fruits of Technology; 2) For a 
Beautiful World; 3) Preserving Mail as a Sensitive Creature; 4) 



Science Education 303 

Man Needs Wilderness; 5) Man and Adaptation-, 6) Conserving our 
Natural Resources; and 7) Man and the Environment. 

Examples of Horizontal Developmental Threads 

The K-12 study of living things is an example of the 
systematic development of a child's understanding of increasingly 
complex material by building each year on the base erected the 
previous year. This study is initiated in kindergarten as the children 
use their five senses to learn about life around them. In succeeding 
years, they discover how living things differ and how they are alike, 
They explore the world of living things and learn that there are also 
similarities and differences in the ways living things acquire the things 
they need and want. Continuing to build their understanding, they use 
similarities and differences in form and function to divide plants and 
animals into groupings. Before completion of grade six, they learn to 
construct and use various kinds of taxonomic keys. The depth of 
understanding they achieve either as individuals or as a class depends 
on their interest and ability. The study of living things continues thru 
the upper five grades. Each of the eight topics which are integrated 
into the existing curriculums in these grades is concerned with one or 
more aspects of living things. The K-6 foundation studies of living 
things are prerequisite to a full understanding of the eight topics. 

Another example which demonstrates both the systematic develop- 
ment of a concept thread and student involvement also starts with the 
study of living things in kindergarten. However, this thread branches 
in grade one from the route taken in the previous example to become 
resource rather than biologically oriented. The children develop in class 
their ideas of the difference between needs and wants. In subsequent 
grades, they find out how the natural resources of planet Earth are used 
to satisfy our needs and wants. They then seek local evidence of prob- 
lems which can be traced to the fact that each year we are using 
resources to meet extensive and growing demands of more and more 
people. The students appraise the influence of advertising, particularly 
the creation of desire for more wants, and the resultant increase in 
resource consumption. A field trip to the local solid waste disposal 
facility focuses on the serious problem of disposal of the child's own 
throwaways. This "needs and wants" thread continues into the eight 
topic areas and broadens the base from which they are studied. 

Throughout the whole system, man's moral responsibility to Earth 
and all its living things is stressed. The child is guided to explore ways 
his own behavior influences the quality of his environment. He forms 
his own ideas of what behavioral patterns are required of individuals 
and both small and large groups if there is to be a quality life for all 
living things. 

The System for Ecological Education is designed to be an educa- 
tional tool with which to shape attitudes and values and to construct 
patterns of behavior which will make each citizen an environmental 

asset.

Soil Colloids and Behavior of Pesticides in Soils. 1 Joe L. White 

and Maribel Cruz, 2 Purdue University, Lafayette, Indiana 47907. ■ 

The interaction of pesticides with soil is largely dependent upon the 
nature and properties of the surfaces of the colloidal components of 
the soil. Interactions of organic molecules with surfaces of aluminosili- 
cate minerals have been studied by infrared and other spectroscopic 
techniques. These studies have provided evidence for the mechanisms 
involved in adsorption, bonding, and degradation of several groups of 
pesticides by inorganic soil components. The role of the higher degree 
of dissociation of water molecules on clay surfaces ("surface acidity") 
in the protonation and hydrolysis of chlorotriazines has been estab- 
lished by this work. These studies also suggest that competition between 
pesticide molecules and water molecules for adsorption sites, together 
with changes in the environment of the pesticide molecules resulting 
from physical adsorption processes, may explain desorption and 
volatilization losses.

The frequency distribution of total suspended particulate matter for 
Indianapolis, Indiana, was examined to determine the precision associated 
with a given sampling scheme. By assuming a basic log e -normal distribu- 
tion, a theoretical set of confidence intervals about the geometric mean 
was derived for random sampling. Verification of the log e -normal distribu- 
tion was made for particulate matter in Indianapolis. Application of the 
derived confidence intervals revealed that for a 30-day period 20 samples 
must be taken to ensure that the 90 per cent confidence interval will be 
within 10 per cent of the geometric mean. Analysis of the records for 19 
sampling locations showed that only 2 sites possessed sufficient data to 
allow monthly climatological evaluation over the period 1968-1970.

High Rates of Urea Fertilizer for Corn (Zea mays L.) on Two 
Soils, 1969-19711 

Russell K. Stivers 

Agronomy Department 

Purdue University, Lafayette, Indiana 47907 

Abstract 

Five rates of nitrogen from urea with accompanying rates of agricultural limestone 
were compared for continuous corn on Fincastle silt loam soil and on Chalmers silty clay 
loam soil. The effects of the urea were similar in both soils, but they were more pro- 
nounced on the Fincastle soil which was lower in both organic matter and in cation 
exchange capacity. In 1969 on the Fincastle soil, the highest rate of urea furnishing 1344 
kilograms per hectare of nitrogen, when applied the day before planting, reduced stands 
of corn to 32 per cent and yields of corn grain to 37 per cent of those which received 336 
kilograms per hectare of nitrogen. In 1970, there was no stand, vegetative growth or 
meaningful grain yield reductions when the same high rates of fertilizer were plowed 
under on the same plots in November prior to seeding in May. In 1971, soluble salts in the 
Fincastle soil were more than doubled, height of plants was reduced 20 per cent, and soil 
pH was reduced 0.9 unit with the 1344 kilograms per hectare rate of nitrogen as compared 
with the 336 kilograms per hectare rate of nitrogen. 

Introduction 

Powell and Webb (3) found that in the third year of continuous corn, 
yields began to decrease above 336 kg per ha (300 lbs per A) or 448 kg 
per ha (400 lbs per A) of nitrogen. They attributed this reduction to 
accumulation of salts and to decreases in soil pH. The purpose of this 
research, which is similar to that of Powell and Webb, is to compare high 
rates of N for continuous corn. 

Methods 

Two soil areas approximately 1 km (0.6 mile) apart were selected 
on the Purdue University Agronomy Farm. The Chalmers silty loam, 
classed as a Typic Arguaquoll, had been well fertilized and limed, as well 
as tile drained, and had been cropped to corn and soybeans (Glycine max 
L.) for several years. The plow layer had a cation exchange capacity of 
32.5 meq per 100 g of soil, contained 4.4% organic matter, had 185 parts 
pp 2m of Bray No. 1 phosphorus (P) and had 675 pp 2m of potassium (K) 
as determined by the Purdue Soil Testing Laboratory. Soluble salts were 
low with a specific conductance of 19 x 10~ 5 mhos. This area is depressional. 
The other soil, a Fincastle silt loam, is classed as a Aerie Ochraqualf. It 
had received moderate rates of fertilization, had been well limed, and had 
been cropped to continuous corn for several years. Cation exchange 
capacity of the plow layer was 16.3 meq per 100 g of soil, and the organic 
matter content was 2.3%. It had 100 pp 2m of Bray No. 1 phosphorus (P) 
and 285 pp 2m of available potassium (K). Soluble salts were low with 
a K value of 16 x 10~ 5 mhos. Tile drainage was inferior to that in the

Chalmers soil. Land leveling was used on the Fincastle soil prior to the 
initiation of this experiment to make the 2-4% slopes more nearly uniform. 

The plot layout was a randomized complete block design with four 
replications of five treatments on each soil. Treatments were no N and 
four rates of N from fertilizer grade urea (45%) and rates of limestone 
as shown in Table 1. Soil samples from all plots were taken in May before 
applying treatments and in August of 1969, 1970 and 1971. Lime require- 
ment was determined by use of the Shoemaker, McLean and Pratt buffer 
(4). Soil pH was determined using a 1:1 soil to water ratio and a Corning 
glass electrode pH meter. The agricultural limestone from the Delphi 
Limestone Company in 1969 had an average of 36% of the particles passing 
through a 60-mesh sieve and 95% through an 8-mesh sieve. The 1970 lime- 
stone from the Newton County Stone Company had 38% passing through 
a 60-mesh sieve and 95% through an 8-mesh sieve. The urea was broadcast 
one day before planting for the 1969 crop and in the previous

November for the 1970 and 1971 crops. In 1969 all fertilizer was broadcast 
after plowing disked, or field cultivated for incorporation. For the 1970 
and 1971 crops broadcast limestone and fertilizers were plowed under in 
the previous November, and field cultivation and spike tooth harrowing 
were used for spring preparation for planting. In all years the urea was 
applied last just prior to disking or plowing. In 1969, 1,190 kg per ha 
(1,065 lbs per A) of 0-11-21 (percentages of total N, available P, and 
available K) were applied to all plots. For the 1970 and 1971 crops 975 kg 
per ha (870 pounds per acre) of 0-11-21 fertilizer were applied each year 
to all plots. 

Broadcast aldrin was incorporated into the soil in 1969 to control soil 
insects. The corn hybrid, DeKalb XL-45, was planted May 29, 1969, and 
Pioneer 3369A was planted May 8, 1970 and May 4, 1971. Average final 
stands were 43,000 plants per ha (17,400 plants per A) in 1969, 54,000 
plants per ha (21,860 per A) in 1970, and 59,000 plants per ha (23,900 
per A) in 1971. In 1970 corn was planted at a high rate and hand thinned 
to an exact population per row. Stand counts were taken in 1970 prior 
to thinning. In 1969 and in 1971 no hand thinning was done. Atrazine 
(Aatrex) and Lasso were used as broadcast pre-emergence herbicides. 
Cultivation was also used for weed control. Corn was planted in 76 cm 
(30 inch) rows in plots 18.3 m (60 feet) long and 4 corn rows wide. Hand 
harvest areas were 7.9 m (26 feet) long and the 2 center rows were used. 
Moisture percentages in the grain and tables for converting ear corn 
weights to shelled corn were used to calculate grain yields. Yields are 
reported on a 15.5% moisture in shelled corn basis. 

Corn ear leaf samples were analyzed for plant nutrients by the 
Growth Sciences Center of the International Mineral Chemical Corpora- 
tion, Libertyville, Illinois. 

Results and Discussion 

The use of the highest rate of urea (1,344 kg per ha or 1,200 lbs per 
A) in 1969, resulted in a decline of 0.7 pH unit in Fincastle soil and 0.5 
pH unit in Chalmers soil (Table 1). In 1971, the soil pH was 5.3 on this 
treatment on the Fincastle soil. According to Barber (1), limestones 
having low percentage of particles passing through a 60-mesh sieve are 
not likely to be efficient in acting rapidly to correct soil acidity. With 36 
to 38% passing a 60-mesh sieve, these limestones were apparently too 
coarse to completely correct acidity in time between application and 
pH measurement. 

Soluble salts in both soils were higher as rates of nitrogen increased. 
This was true in both 1969 and in 1971 (Table 1). Soluble salts were not 
determined in 1970 when no growth irregularities were observed. In 1969 
differences in numbers of plants per plot and yield related to treatment 
were observed (Table 2) even with 4.5 cm of rain in the 10 days following 
planting. In 1969 the stand (number of plants per plot) on the 1,344 kg 
per ha rate of nitrogen from urea was reduced to 33% and yields of corn 
grain were reduced to 37% of those which received 336 kg per ha of nitro- 
gen. This reduction in stand cannot be attributed entirely to salt effect.

Hunter and Rosenau (2) found that in closed urea-soil systems, urea-soil 
mixtures out of contact with germinating corn seeds released gaseous 
ammonia into the atmosphere, and the ammonia inhibited germination 
and affected seedling development of corn. Similar effects were noted 
when corn was seeded in soils saturated with ammonium ion to the extent 
of 32% or more. The 1,336 kg per ha rate of N used herein would, if care- 
fully mixed and all the ammonia (from urea) were absorbed on the 
exchange sites, saturate 80% of the cation exchange capacity of Fincastle 
soil and 40% of the exchange capacity of Chalmers soil. Highly significant 
reductions in stand were found at this rate of N on both soils. However, 
at the 672 kg per ha (600 lbs per A) rate of N, stand was reduced signifi- 
cantly only on the Fincastle soil. In all years N deficiency symptoms were 
observed on both soils in the no nitrogen treatment. In 1971, a year of 
high corn yields, these symptoms of N deficiency were severe. The 
significantly lower grain yield on both soils of the 672 kg per ha rate of 
N than the 1,344 kg per ha of N in 1970 was not thought to be meaningful 
because the 336 kg per ha treatment was also higher yielding. The general

trend in yield was very slightly higher in rates above none. This trend 
was the result of heavier ears with the higher rates of N. 

In 1971, even though grain yields were not reduced significantly, 
maximum leaf heights were reduced significantly at the two highest rates 
of N in the Fincastle soil and at the highest rate on Chalmers soil (Table 
2). Total soluble salts and also nitrates were high in these two highest 
treatment rates of N from urea on Fincastle soil. Soluble salts were not 
as high on the Chalmers as on the Fincastle soil at the highest rate of 
N in 1971. High soluble salts in soil probably contributed to the reduced 
rate of growth of corn in the highest treatments on the Fincastle soil. 
Height of plants was reduced 20% on the Fincastle soil and to only 9% on 
the Chalmers soil in 1971. Germination and stand were not measurably 
affected by high rates of N, and neither were grain yields. 

Plant analysis on corn ear leaves indicated that contents of 
manganese (Mn) increased from 4 to 15 times as rates of nitrogen were 
increased from to 1,344 kg per ha (Table 3). This increased uptake of 
Mn was associated with a lower soil pH. Content of Mn in the ear leaves 
was 2 to 3 times as high from the 168 kg per ha rate of N on Fincastle 
soil as from the same rate of Chalmers soil. Soil Mn determinations were 
not made.

In conclusion, high rates of urea (672 or more kg per ha of N) 
incorporated into the plow layer of soil just before planting can reduce 
germination and yield of corn. Also, high rates of urea can cause soil pH 
to decline as much as 0.7 of one pH unit in one cropping season. After 
three applications of high rates of urea and two applications of limestone 
in three cropping years, soluble salts can become high enough to contribute 
to reduced maximum leaf height of corn in late June particularly on the 
low exchange capacity and low organic matter Fincastle soil.

Abstract 

Daily total suspended particulate concentrations for the period of 1968-1970 at 
Indianapolis, Indiana, were analyzed to illustrate the weekly and seasonal variation in 
urban air pollution. Weekly and seasonal changes in air quality as measured by daily total 
particulate concentrations are identified; comparisons are made between the maximum 
monthly concentrations and the mean monthly frequency of stagnating anti-cyclones. 
Mean annual area concentrations for daily periods as measured by 19 monitoring stations 
in Indianapolis and Marion County, Indiana, are illustrated. Some reasons for the recorded 
changes in daily, weekly, and seasonal air quality in Indianapolis are proposed. 

Introduction 

It is generally understood that air pollution concentrations change 
from hour to hour, day to day, and from one season to another during 
the year. These variations have many causes, some of which are well 
understood. Extremely high levels of air pollutants are related primarily 
to very stable stagnating meteorological conditions for several days. 
Likewise, extremely low levels are related to very unstable 
meteorological conditions. But the normal hour to hour and day to day 
meteorological change, coupled with time and space changes in human 
activity in a given urban area, usually produces substantial periodic 
patterns in air pollution concentrations. These pattern changes must 
be properly assessed when planning a sampling procedure for the 
purpose of monitoring air pollution concentrations. Sampling at fixed 
times and places can produce highly biased data. It is for this reason 
that the authors took a rather critical look at periodic changes in air 
pollution concentrations of total suspended particulate over a 3-year 
period at Indianapolis, Indiana. 

Data and Methods 

Data used in this study consisted of 24-hour samples of total sus- 
pended particulate concentrations from 19 locations in Indianapolis, 
Indiana, from January 1, 1968, through December 31, 1970. These daily 
values were in micrograms per cubic meter (^,g/m 3 ). The data

7 days in a weekly period is an average of 111 values. Similarly, 
all daily values falling within a given month were composited to produce 
monthly mean values. These data were subjected to an analysis of vari- 
ance reported in Tables 1 and 2, and in Figures 2 and 3. Site 1 air 
sampling station is located near the City-County Building in downtown 
Indianapolis. 

Results and Discussion 

The National "Clean Air Act" passed by Congress in 1967 has many 
provisions, regulations, and suggestions as guidelines for achieving its 
goals. This Act clearly states that all areas within the United States 
shall come under the control of a State or Federal designated Air 
Quality Control Region. Further, the Act provides general guidelines 
and timetables for achieving compliance. 

One of the goals as stated in guidelines, under the 1967 Clean Air 
Act, is that all areas in the United States should achieve an air 
quality, as measured by total suspended particulate matter, of 80 /xg/m 3 
per 24 hours for an annual mean value. 

With this in mind, the authors summarized 3 years of daily total 
suspended particulate samples collected within the City of Indianapolis 
and Marion County to produce Figure 1. This figure provides an esti- 
mated geographical picture of that area in Indianapolis where the air 
quality exceeded that annual mean value of 80 /xg/m 3 per day. 

Once an air pollution problem area has been established, further 
monitoring must be continued to establish whether or not a geographical 
area has or has not achieved the goal of compliance for a given air 
pollutant. If one could assume that air pollution levels did not change 
much from hour to hour, day to day, and month to month, then only 
a few sampling days during the year would be adequate for establishing 
compliance within a given Air Quality Control Region. Secondly, if one 
could assume the air pollutants' changes in concentration were strictly 
random in time and space, then only enough samples to estimate the 
statistical error desired would be necessary. Unfortunately, neither of 
these two assumptions is likely to hold. 

It is well known that air pollutants vary both in time and space. 
Over a yearly period or longer, variations in space are closely related 
to sources of pollutants in a given area. On the other hand, variations 
in time are closely related to changes in meteorological conditions and

the total activities of the community concerned. Since Figure 1 illus- 
trates the mean estimated variation in space for the City of Indi- 
anapolis, the authors decided to subject the data to an analysis of vari- 
ance in time at a given point. For this study, Site 1 was selected near 
the geographic center of Indianapolis. All daily values that were 
consecutive in 7-day runs over the 3-year period at Site 1 were subjected 
to this time-series analysis. The results of this effort are graphed in 
Figure 2, with the analysis of variance reported in Table 1.

Figure 2 illustrates considerable change from day to day during 
the normal 7-day calendar week in mean daily total suspended 
particulate for Indianapolis. These mean changes from day to day 
during a weekly period are very significant as shown in Table 1. This 
analysis strongly suggests that taking air quality samples on one or 
two fixed days during a 7-day week is likely to produce biased data. 
The one day with the least bias in this analysis turns out to be Friday, 
since it is the mean daily value closest to the estimated weekly mean 
value. 

A similar analysis was done for monthly periods. These results are 
reported in Figure 3 and Table 2. Here again, considerable variation 
exists in mean daily value of total particulate from one month to an- 
other and particularly between seasonal periods. The highest values 
occur during the summer season, particularly in August. The lowest 
seasonal values occurred in late autumn and early winter with the 
lowest in November.

usually associated with an extended period of extremely stable 
meteorological conditions. Therefore, it was decided to compare the 
results graphed in Figure 4 with the results reported by Korshover (1) 
on the mean number of cases per month of anti-cyclone stagnations in 
a 30-year period (1936-1965) for Indianapolis. Korshover's results are 
graphed in Figure 5. Note the unusually high number of cases in 
August, September, and October. Since Korshover's results represent 
a climatic norm, one can conclude that high levels of air pollution for 
extended daily periods should be expected during the late summer and 
early autumn at Indianapolis, Indiana. 

This analysis shows that periodic sampling of air pollutants, as 
has often been the practice of air quality control districts, can result 
in seriously biased data. The reason for this possible bias is related to 
the fact that air pollution concentrations are subjected to periodic 
changes caused by the area patterns of total community activities and 
seasonal changes in meteorological conditions. Biased data from an air 
quality sampling network can be reduced by avoiding fixed sampling 
periods, such as one particular day per week or a particular set of days 
per month. Therefore, air quality samples should be taken in a manner 



318 Indiana Academy of Science 

that minimizes the error in estimating the true mean for the period 
concerned. 

It is generally accepted that air pollution concentrations vary from 
hour to hour during a normal 24-hour period. But since no hourly data 
existed at Indianapolis, the diurnal period could not be studied. Nor- 
mally, the highest concentrations occur during the early morning hours 
of 7 to 9 am, with the lowest values occurring between 1 and 
4 PM. 

Conclusions 

From air quality data on total suspended particulate at Indi- 
anapolis, Indiana, from January 1, 1968, through December 31, 1970, 
it is concluded that day to day weekly variations and month to month 
seasonal variations are significant. Therefore, periodic sampling of air 
pollutants on fixed days of the week should not be practiced without 
proper correction procedures. Otherwise, seriously biased estimates in 
air quality can result.

Temperature and Relative Humidity Inside Corn Canopies 
and in Standard Shelters during July and August, 1970 and 1971 1

Abstract 

Temperature and relative humidity within the microclimate of corn canopies were 
compared to macroclimate temperature and relative humidity recorded in a standard 
National Weather Service shelter for the period July 17 to August 15, 1970 and 1971. 
Unaspirated wet bulb and dry bulb thermocouples exposed at one meter were used to 
measure corn canopy temperature and relative humidity. A hygrothermograph was 
exposed in a shelter for macroclimate measurements. Corn canopy maximum 
temperatures were higher than shelter maximum temperatures and, conversely, corn 
canopy minimum temperatures were lower than shelter minimums during both years. 
Relative humidity within the corn canopy during this period was similar in both years al- 
though differences occurred in macroclimate relative humidity patterns. 

This study suggests that temperatures obtained from standard National Weather 
Service shelters can be used to approximate temperatures within a corn canopy. 
Relative humidity, however, can be quite different within a corn canopy than within a 
standard shelter. 

Introduction 

Following any unfavorable agricultural situation such as delayed 
corn maturity in 1967 or the unprecedented development of Southern 
Corn Leaf Blight (SCLB) in 1970 and 1971 (3), agriculturists often 
look first to anomalous weather conditions for an explanation. Weather 
data are collected and published by the National Weather Service from 
a network of instruments exposed under standard conditions. These data 
furnish excellent macroclimatic comparisons, but unless relationships 
between these data and microclimatic conditions are known, a correct 
assessment of the effect of macroclimatic anomalies upon biological 
response within a micro-environment can only be hypothesized. 

This paper describes temperature and relative humidity patterns 
observed within a corn canopy and compares them with those from 
standard instrumental exposures for a period from mid-July to mid- 
August in 1970 and 1971. These microenvironmental measurements were 
taken as part of a corn growth and development study conducted at the 
Purdue University Agronomy Farm, West Lafayette, Indiana. 

Description of Experiment 

A summary of published temperature data (4) for the 1970 and 
1971 growing seasons and the 18-year (1953 to 1970) average for the 
Purdue University Agronomy Farm is shown in Table 1. In this study, 
a 30-day period from July 17 to August 15 — a period important in the 
SCLB development — was examined during both years.

Environmental temperature and relative humidity data were from 
a hygrothermograph exposed in a medium National Weather Service 
shelter at the Purdue Agronomy Farm Agricultural Weather Station. 
The corn experimental area was located about 200 m north-northeast 
of the weather station. Corn population was about 62,000 plants per 
ha planted in 76 cm-wide rows oriented north to south. The corn 
canopies were approximately 2.7 m tall in both years with an average 
leaf area index during the study period of 3.5 in 1970 and 4.0 in 1971. 
Seventy-five per cent silk dates were August 3, 1970 and July 27, 1971. 

Copper-constantan thermocouples (24-gauge wire) were utilized to 
measure dry and wet bulb temperatures at 1 m within the corn canopy. 
Dry bulb fluctuations were reduced by shielding the thermocouple 
junction with white tape. A wet bulb was formed by tying a muslin wick 
securely around a bare thermocouple junction and extending the muslin 
downward into a water reservoir. Output from the thermocouples was 
recorded on a multi-point recorder. 

Relative humidities measured by wet and dry bulb thermocouples 
were compared with those from a hygrothermograph exposed at the 
same location within the corn canopy during September 1971. The 
hygrothermograph used in the corn canopy was calibrated with the 
shelter hygrothermograph before and after the September study. The 
least squares regression equation for the calibration period was 
Y = 1.718 X — 70.266, where Y is relative humidity taken 
from the hygrothermograph and X is that from the thermo- 
couples. R 2 was 0.83. Since relative humidity in the shelter was 
recorded with a hygrothermograph, corn canopy relative humidities 
calculated from wet and dry bulb thermocouples data were corrected 
by this equation for this study. 

Results and Discussion 
Temperature 

Temperatures in the shelter for the period from July 17 to August 
15, 1970 and 1971 are shown in Figure 1. Daily maximum and 
minimum temperatures during 1970 were close to normal with periods 
both above and below normal. In 1971, daily maximum and minimum 
temperatures were well below normal with only a short period in August 
having above normal temperatures.

Hourly shelter temperatures averaged for the 30-day period from 
17 July to 15 August show that 1971 temperatures were 2 to 3°C lower 
than 1970 temperatures (Fig. 2). An average hourly standard deviation 
of 1.3°C was found in 1970 and 0.9°C in 1971. 

Differences between temperatures in the canopy and in the shelter 
for each hour are also shown in Figure 2. Nighttime temperatures 
within the canopy averaged 1.5°C lower than those in the shelter 
during 1970 and 0.5 °C lower in 1971. Midday temperature differences 
reached a maximum of 1.2°C greater in the canopy than in the shelter 
during 1970 and 0.6°C during 1971. This difference between the two 
years can partially be explained by a denser canopy leaf area in 1971 
than in 1970. The 1971 canopy did not permit as great a radiational 
exchange between the 1 m level in the canopy and the macroenviron- 
ment as did the 1970 canopy. Radiational heating and cooling of the 
canopy interior was therefore less during 1971 than during 1970. The 
early evening hours were a time of greatest temperature differentials 
between the macroenvironment (shelter) and the corn canopy. Rahn 
and Brown (2) have also found the corn canopy microenvironment to 
be warmer in daytime and cooler at night than the macroenvironment 
as measured in an instrument shelter. 

Temperature differences in Figure 2 could reflect differences 
between exposures and also differences between types of instruments, 
i.e., thermocouples within the canopy and a hygrothermograph in the 
shelter. The temperature data shown in Table 1 are from a third type

of instrumentation, liquid-in-glass maximum and minimum ther- 
mometers. Accuracy in reading both time and temperature from 
hygrothermograms and thermocouple charts defeat quantification of 
any estimate of bias due to instrumental differences 2 . 

If temperature differences shown in Figure 2 are used to estimate 
maximum, minimum, or mean temperatures within a corn canopy from 
published climatological data, bias arising from the time of observation 
must be considered. Mitchell (1) has shown that estimates of mean 
temperature were near the true daily mean if the observational day 
ended at 8:00 am, but the maximum and mean temperatures were 
biased upward if the observational time was 5:00 PM. An 8:00 AM 
observational day was used in this study for summarizing all tempera- 
ture data. 



2 Published (4) maximum temperatures from ]iquid-in-g]ass thermometers averaged 
0.6°C higher and minimum temperatures 0.7°C lower than those from a hygrothermo- 
graph exposed in the same standard shelter. A hygrothermograph and thermocouples 
exposed at 1 m within a corn canopy during September 1971, recorded the same night- 
time minimum temperatures. Daytime maximum temperatures, however, were recorded 
about 1°C higher on the hygrothermograph. The higher daytime temperatures were 
due to sunfleck heating of the hygrothermograph while thermocouples remained in 
shaded locations during both the July-August and September periods.

Relative Humidity 

Three basic instruments are used by the National Weather Service 
to measure relative humidity. Hygrothermographs, of the type exposed 
in a shelter for the data in this paper, depend upon absorption of water 
vapor by human hair. Hygrothermometers of the type currently exposed 
at airport weather stations consist of a ventilated dew cell to obtain 
dew point data. Relative humidity measurements with this instrument 
are usually lower than those recorded by a hygrothermograph. A third 
type instrument is the wet and dry bulb psychrometer. Although the 
psychrometer is usually force ventilated, an unaspirated thermocouple 
version of this instrument was used for canopy measurement of relative 
humidity in this study. 

Relative humidity data in the corn canopy were not recorded prior 
to July 26, 1970. Thus hourly relative humidities in the shelter and 
canopy were averaged for the 21-day period from July 26 to August 15 
(Fig. 3). The 1970 hourly relative humidities in the shelter were 
generally higher than those in 1971. The largest differences, 5% to 
10%, occurred during the morning hours. The 1970 and 1971 corn 
canopy relative humidities, however, were similar throughout the day.

Relative humidities in both the shelter and corn canopy were close to 
100% during the nights in both years. 

Hourly relative humidity differences, canopy minus shelter, were 
similar during the night, afternoon, and early evening hours in both 
years (Fig. 3). Morning relative humidities, however, did not show 
similar characteristics in 1970 and 1971. During 1970, relative humidity 
in the corn canopy and shelter changed at about the same rate until 
2:00 PM, but in 1971 the shelter relative humidity decreased more 
rapidly in the morning than did the corn canopy relative humidity. 
Hourly standard deviations of the relative humidity differences were 
about 3% at night and 10% in the afternoon. The large afternoon 
deviations were caused by a few periods of rain and high humidity. 

Conclusions 

During the 30-day period, July 17 to August 15, 1970 and 1971, 
temperatures at 1 m within a corn canopy were lower at night and 
higher during the day than temperatures recorded in a standard 
National Weather Service shelter. The shelter relative humidity was 
greater in 1970 than in 1971 with the largest differences occurring 
during the morning hours. Relative humidities within the corn canopy, 
however, showed similar average hourly trends during the morning 
hours in 1970 and 1971. Relative humidity in both the corn canopy and 
shelter averaged close to 100% at night in both years. 

These data suggest that temperatures obtained from standard 
National Weather Service shelters can be used to approximate 
temperatures within a corn canopy. Relative humidity, however, can 
be quite different within a corn canopy than within a standard 
shelter.

Abstract 

A disease simulator model was used on an experimental basis during 1971 to 
evaluate the effects of weather on the spread and multiplication of Southern Corn Leaf 
Blight. Weather data consisting of hourly temperature, humidity, wind speed, sunshine, 
leaf wetness and precipitation were used in the computer program to provide daily values 
for new infections, lesion accumulations and per cent leaf area affected. Results were then 
compared to observations provided through pathological reports, ground observer data 
and aerial photo-multispectral scanner information.. Weekly EPIMAY predictions 
compared favorably with the observed weekly change in blight. At stations where 
starting dates of EPIMAY and the initial observed infection were close, good comparisons 
resulted for per cent leaf area infected. 

Introduction 

During 1970 southern corn leaf blight, race T of Helminthosporium 
maydis, reduced corn yields in the United States by an estimated 10 
to 15% according to crop reports of the U.S.D.A. Statistical Reporting 
Service. Losses were confined mainly to corn hybrids containing Texas 
male sterile-cytoplasm. The disease started in the Southern United 
States in May and June, then spread rapidly into the midwest corn belt 
during July and August (1). Some fields of corn in Indiana were com- 
pletely destroyed by the epidemic. 

Considerable effort was made during and following the 1970 grow- 
ing season to establish the effect of weather on the development of the 
disease. EPIMAY, a disease simulator model, was developed by Dr. 
Waggoner and associates at the Connecticut Agricultural Experiment 
Station (2). The model was based on application of 1970 observed 
weather-disease information and laboratory tests. The results showed 
promise for application as an objective indicator of the favorability of 
weather for the development of southern corn leaf blight. 

Barger (NOAA, EDS, Wash., D.C.) suggested national use of 
EPIMAY for the corn blight problem and in June 1971 a program, under 
the direction of Regional Climatologist, L. A. Joos (Joos, unpublished 
data), was established using computer facilities at the National 



Journal Paper No. 4611. Purdue University Agricultural Experiment Station.

Weather Service Central Region in Kansas City. The program was 
conducted over a 12-state area and included about 20 stations. To 
supplement and assist in evaluating the national program, an intensive 
application of the EPIMAY model was conducted at Purdue University 
for 8 stations in Indiana. 

The Indiana program was a joint cooperative effort by research 
and operation groups at Purdue to identify and evaluate southern corn 
leaf blight by aircraft sensing and by collection of field observations, 
and thus testing the predictability of EPIMAY (using weather data). 

In addition to airborne information, the Corn Blight Watch Experi- 
ment conducted by the USDA, NASA and Universities in seven Corn 
Belt States provided an organized collection of ground truth by 
extension agents and pathologists in a specific series of fields along 
the designated flight paths for sensing aircraft (Bauer, M., unpublished 
data). 

Methods 

The disease simulator model estimated the effects of temperature, 
humidity, wind, light and leaf wetness on all stages of the disease 
cycle. Other factors involved were effects of wind and rainfall on wash 
off, dry out and transport of spores. To determine the number of 
lesions formed, the model systematically considered the factors relating 
to spore production, dissemination and infection by the blight fungus. 
This was accomplished by a series of laboratory developed curves relat- 
ing the single and combined effects of weather on the disease. Some 
modifications were made in the model by Purdue researchers to adjust 
for change in leaf area available for infection and to adjust starting 
dates to fit planting and various development stages of the corn crop 
(Peart, R., and O. Loewer, unpublished data). 

Weather input to EPIMAY for the national and Indiana programs 
were provided by the daily reports from the Indiana agriculture weather 
observation network and by hourly teletype reports from the National 
Weather Service and Federal Aviation Agency teletype reporting sta- 
tions. Data for each 3-hour period through the day, beginning at mid- 
night Greenwich time (7 pm EST), were summarized, resulting in 8 
data readings per 24-hour period from June 11 through September 2. 
Dew or leaf wetness were rated in five classes: no dew — zero 
duration, light dew — 3-hour duration, moderate dew — 6-hour duration, 
heavy — 9-hour duration, and very heavy — 12-hour duration. Dura- 
tion of classes was determined through instrument measurements 
and visual checks. When dew was present hygrothermograph traces 
usually indicated 80 to 100% relative humidity. Light or brightness of 
the sky information was based on cloud cover from sunrise to sunset 
using 50% or greater cloudiness as a cloudy day. The data were 
punched on computer cards each Friday for processing by the LARS 
computer facility. 

The computer output consisted of a daily listing of weather data 
including the starting, ending and inches of rainfall for each precipi-

tation period, leaf wetness as yes or no, and hourly rate of rainfall 
for each 3-hour period for checking the input data. Next came the 
results, a daily listing of new infections, new lesions, accumulated 
lesions and per cent of leaf area infected by lesions. Map summaries 
showing accumulated lesions, weekly increase and per cent leaf area in- 
fected at each location were then prepared for distribution to all 
Purdue groups and by telecopier to Climatology Research Laboratory, 
NOAA, Silver Springs, Maryland. 

Results 

EPIMAY estimated the number of blight lesions formed daily and 
provided accumulative totals for each station. Flat plateau-like portions 
of the curves (Fig. 1) indicate when weather was unfavorable for blight

Reasonable agreement was found at 5 of the 8 locations where 
weather data and sample fields were near and quite poor agreement 
elsewhere. 

Weekly increases in number of lesions were used to indicate the 
degree of favorability of weather for blight development (Table 2). 
Favorable weather produced 7 day lesion increases up to 39 times the 
number for the previous week. 

Discussion 

A number of limitations prevent conclusive evaluation of EPIMAY. 
In most cases, except at the Purdue Agronomy Farm, West Lafayette, 
and at Wanatah, weather stations were at distances of several miles 
to over 20 miles from the sampled corn fields. Variation from local in- 
fluences of topography, soil moisture and rainfall patterns for these 
distances could account for some of the differences between observed 
and predicted disease levels (Table 1). A starting condition of 100 initial 
lesions per hectare were used for EPIMAY but large variation could 
occur in this level due to local inoculum sources. 

It was also necessary to adjust EPIMAY to account for per cent 
of leaf area remaining available for new infections (Peart, R., and 0. 
Loewer, unpublished data). Further adjustments of leaf area indices 
are needed to account for different planting dates and stages of 
development of corn. 

Other factors contributing to variation in results that should be 
considered are the susceptibility of different corn hybrids and the 
general physical status of the crop from other diseases and insects. In 
1971, early planted susceptible corn varieties matured far enough ahead 
of the late developing southern corn leaf blight to limit damage 
mainly to foliage and stalks. 

The overall effects of the 1971 corn growing season also has some 
bearing on the 1971 southern corn leaf blight situation. Winter and 
early spring dryness and summer coolness were effective in reducing 
spore viability in the 1970 crop residue. No large scale influx of spores 
were noted by pathologists as in the previous year. Early planting plus 
a warm very rapid spring growth period caused corn development earlier 
than usual before blight fungus development. These plus other factors, 
such as reduced acreage of susceptible corn, were among the reasons 
for Indiana's improved blight picture.

Some Effects of Soil and Ambient Air Temperature

Abstract 

An experimental laboratory study was designed to evaluate the effect of temperature 
difference combinations on the growth response of tomato seedlings. Growth indices were 
changes in stem diameter, root-mass length, and stem height. The stem diameter was con- 
tinuously monitored with a specially designed electronic micrometer. 

An endogenous cyclic pattern of change in stem diameter was noted as a function of 
the light and dark intervals. Increases in root temperatures up to 35 "Centigrade 
(95° Fahrenheit) for periods of approximately four days had at least temporary bene- 
ficial effects on growth. However, further increases in root temperature were deleterious 
to growth, particularly root development. 

Introduction 

One of the most troublesome environmental problems in the 
United States is thermal pollution in water. It is readily apparent, due 
to the importance of temperature on metabolic and respiratory proc- 
esses of living organisms, that release of large volumes of heated water 
to waterways and lakes can be an upsetting influence on natural life 
cycles. Heated waste water, because of its low grade temperature con- 
dition, has little industrial value and controls are both costly and 
complicated. Mechanical cooling towers and cooling ponds are the most 
common methods of controlling waste heat output but both are rather 
inefficient with little capital return accruing to their use. A possible 
alternative would be to find beneficial uses of the heated waste water. 

One proposed solution is to use the heated water for irrigation and 
environmental control of crops. However, depending on the means of 
application of this water to plants, relatively large temperature 
gradients between plant tops and the root systems could exist. 

The purpose of the reported study was to evaluate some of the 
effects of soil and ambient air temperature differences on the growth 
response of tomato seedlings which might occur as a result of using 
thermally polluted water as the source of water for irrigation (1).

Plant growth may be defined as cell multiplication with or without 
an increase in volume or an increase in volume without cell multiplica- 
tion. In the reported study only non-destructive measurements of volume 
were used as indices of plant growth. Measurement of stem diameter 
was after Splinter (5) who reported on the design of an electronic 
micrometer using a linear variable differential transformer to give 
continuous monitoring of plant stem diameter. Using this device, he 
also showed a high correlation coefficient between stem diameter and 
total leaf area for plant species exhibiting apical dominance. 

The effect of temperature gradients between plant tops and their 
root systems has been previously investigated (4) but more so in recent 
years (3, 6) because of the possibility of thermally polluted soil water 
and because of improvements in instrumentation and experimental con- 
trol. Currently, Boersma from Oregon State University is studying the 
effects of heating soil under field conditions by using buried electrical 
cables to simulate irrigating with thermally polluted water (2). 

Equipment and Procedure 

Three-week old tomato seedlings (Heinz 1350) were "transplanted" 
from a gravel to a mist culture. Transplanting was accomplished by 
securing a plant stem in the top side of a root environmental 
chamber with a cork and floral putty so that the root system would 
extend into the chamber. The root environmental chamber was in turn 
contained within a larger growth chamber as shown in Figure 1.

Nine different root-top temperature combinations were used. Ambi- 
ent air temperatures of 20 and 25°C were combined with 5°C 
increments of "soil" temperatures ranging from that of the ambient 
air to 40°C. 

In the root environmental chamber, the plant roots were continu- 
ously sprayed with modified Hoagland's #1 nutrient solution. The 
temperature of the solution was controlled by a temperature probe, a 
proportional temperature controller, and a heater to ±0.25°C 
once equilibrium conditions were established. The root environmental 
chamber, which was transparent, was covered to provide a darkened 
space for root growth. 

In the growth chamber, the air temperature was controlled at either 
20 or 25°C ± 0.3°C, the relative humidity at 70 ± 2%, and the 
light intensity at 1200 ± 100 ft-c. The day was divided into 16-hour 
continuous light and 8-hour continuous dark periods. 

The growth response of the tomato seedlings was evaluated from 
changes in stem diameter which were continuously monitored with an 
electronic micrometer and from changes in root-mass length 
and stem height over the time period for each experiment. Each 
experiment lasted approximately 4 days. For any one experiment only 
the stem diameter of one tomato plant was measured. The equipment 
used to measure stem diameter consisted of an LVDT (linear variable 
differential transformer) head assembly, an oscillator/ demodulator 
(Automatic Timing & Controls, Inc., Series 6101E) and a potentiometric 
strip chart recorder. This equipment is schematically represented in 
Figure 1 and the LVDT head assembly in position for monitoring change 
in stem diameter is shown in Figure 2.

The LVDT (ATC No. 6233 A) was enclosed in a precisely machined 
central housing. The head assembly was constructed of non-magnetic 
stainless steel and Plexiglas to prevent stray electrical current inter- 
ference with the LVDT. A micrometer head (Starret Co. T263RL) was 
used to provide precise mechanical positioning of the LVDT armature 
in the center or null position of the coil. 

The LVDT head assembly provided a non-destructive means of 
measuring stem diameter. The only back pressure, considered negligible, 
was caused by a small coil spring which was used to keep the 
LVDT in constant contact with the plant stem. When operating, the 
oscillator/demodulator was used to excite the LVDT primary coil, 
amplify the a-c output with phase sensitivity and convert it to a 
d-c signal suitable for direct readout on the strip chart recorder. The 
readout was thus directly proportional to the differential transformer 
armature displacement. Readings of 10~ 3 mm were considered 
accurate without readout interpolation. 

Results and Discussion 

The growth response of a tomato plant with leaf temperatures of 
20 and 25 °C, respectively, and root temperatures ranging from 20 to 
40°C are shown in Figures 3 and 4. These curves were smoothed 
through many data points which also exhibited diurnal fluctuations. 
At a 40 °C root temperature for both leaf temperatures, increases in stem 
diameter did not occur after 72 hours. Prior to this time, the roots of

the tomato plants showed little secondary root growth and were much 
darker in color than had been observed with any of the lower root 
temperatures. However, little visual damage to the leaf and stem por- 
tions of the plants was noted up to 72 hours but by 96 hours severe wilt- 
ing and obvious death had occurred. 

For all root temperatures less than 40°C, the stem diameter in- 
creased throughout the length of the experiment for both leaf 
temperatures. Trends if any between these root temperatures were not 
discernible for a given leaf temperature. However, increases in stem 
diameter were more linear for the 20°C than for the 25°C 
temperature during this stage of plant growth. 

Effects of root temperature on the growth rate of tomato plants 
as measured by stem and root-mass lengths are shown in Figures 5 and 
6. Both the stem and root-mass lengths are the average of three 
tomato plants for any one experiment. The maximum growth rate as 
measured by stem length occurred at a 30° C root temperature for both 
the 20 and 25 °C leaf temperatures. The growth rate for the 
25 °C leaf temperature, however, was about double that of the 
20 °C leaf temperature. The maximum growth rate as measured by 
root-mass length occurred when the root temperature was 5°C 
higher than the leaf temperature. The 25°C leaf temperature condi- 
tion produced about 1.5 times the growth rate of the 20°C 
leaf temperature when root-mass length was used as the growth index. 
The optimum temperatures for obtaining maximum stem and root- 
mass growth in these experiments were 25° C leaf and 30° C 
root temperatures.

diameter tended to decrease over the latter portions of both the light 
and dark intervals. This condition may have been caused by 
"fatigue" during the light periods and consumption of photosynthetic 
products during the dark periods. A rapid increase in stem diameter 
always occurred shortly after the climate chamber was darkened. This 
rapid increase in growth was probably caused by a change in the water 
regime within the plant. Turgor pressures tended to increase rapidly 
because of the closing of the stomata in the absence of light and be- 
cause of the probable cooling of the leaves which would cause the energy 
available for transpiration to decrease.

Conclusions 



Based on this study, the optimum temperatures for this stage of 
tomato plant development appear to be 25°C (77°F) leaf and 
30°C (86°F) root temperatures. At these temperatures, the 
rate of growth as measured by increases in stem length and root-mass 
length was maximum. The rate of growth as measured by increases 
in stem diameter, although not always maximum under these tempera- 
ture conditions, was always high. A continuation of these optimal 
conditions might be expected to result in maximum fruiting but this 
is only conjectural. 

The LVDT head assembly provided a versatile and highly precise 
means of measuring changes in stem diameter in a non-destructive 
manner. Its precision was illustrated in the manner by which it was 
able to measure the small cyclical changes occurring between light and 
dark periods. 



Soil Science 337 

At 40°C (104°F) root temperature, the tomato plants died. The 
deleterious effect of this temperature was quickly noticed by the con- 
dition of the root system but approximately 3 days passed before it 
became noticeable from measurements of stem diameter. For lower 
temperatures, growth trends as measured by changes in stem diameter 
were not discernible. At this particular stage of tomato plant growth, 
measurement of changes in stem diameter should be coordinated with 
other growth indices and visual inspection to give much information con- 
cerning overall plant response. However, each type of measurement can 
yield useful information about certain physiological responses of the 
plant. 

Heated waste water usually varies anywhere from 25 (77°F) to 
50°C (122°F). Over the first half of this temperature range, direct ap- 
plication of the heated waste water to the soil would probably give 
beneficial growth results. However, over the last half of this tempera- 
ture range, some cooling of the water should be accomplished during 
the application process. Under these conditions, sprinkler irrigation 
should be considered because the spray drops tend toward equilibrium 
with the wet-bulb temperature. The major objection to the use of heated 
waste water by tomato plants or for that matter any plant is not 
whether it can be beneficially used — it can — but the fact that it 
may be largely a consumptive use. Over-irrigation and the collection 
of return flow for reuse could reduce the percentage of applied water 
lost to consumptive use, however.

Perception of the Plane of Polarized Light and Its Use by Orienting 

Salamanders. 1 Kraig Adler, Department of Biology, University of Notre 
Dame, Notre Dame, Indiana 46556, and Douglas H. Taylor, Department 
of Zoology, Miami University, Oxford, Ohio 45056. — —Tiger sal- 
amanders (Amby stoma tigrinum) were trained to move along a specific 
axis in an indoor tank under a polarized light (produced by a 
polarizing filter, HN-38 Bausch & Lomb). Orientation tests were per- 
formed indoors in a small water-filled arena which was completely en- 
closed in opaque plastic. Animals were placed individually in the 
center of the arena beneath the polarized light source, then released 
and allowed to move to the edge of the arena where they were 
scored. Directional responses of salamanders in the arena were the same 
with respect to the plane of polarization as they had been in 
training. Rotation of the polarization filter by 90° produced cor- 
responding changes in the direction of movement. 

Orientation to the plane of polarization can be demonstrated in 
sighted and blinded animals. However, if opaque plastic is inserted over 
the skull of blinded animals, movement is at random; oriented movement 
is restored, however, when clear plastic is substituted in these 
animals. These studies suggest that the critical receptor for polarized 
light is extraoptic.

an extensive mark and recapture study of Cryptobranchus alleganiensis 
bislwpi was made on the North Fork River, a branch of the White River, 
Ozark, Co., Missouri. It was estimated that there are 1,142 salamanders 
in a 1.65 mile study area (N = 439). From length and weight measure- 
ments, it appears that the population consists of at least four age 
groups. According to a biomass estimate, there are 919 pounds of 
C. alleganiensis bishopi in this area. One riffle has a density estimate of 
one hellbender per 182 square feet.

Observation of feeding activities as well as stomach analysis indi- 
cates that crayfish are the principal food source of C, alleganiensis 
bishopi. Cannibalism and egg-eating, which have been observed in the 
laboratory, may be important factors in maintaining population stability. 

Specific Estrogen Binding Sites in the Nuclear Fraction of the Rat 
Uterus. J. H. Clark, J. A. Anderson, and E. J. Peck, Jr., 
Department of Biological Sciences, Purdue University, Lafayette, 
Indiana 47907.— — Numerous investigations have demonstrated that the 
interaction of estradiol -17/3 with the rat uterus is probably a two-step 
process in which the estrogen first binds with a cytoplasmic component 
to form a complex which subsequently moves to the nucleus. A method 
has been developed for the determination of the number of these 
nuclear binding sites in estrogen sensative tissues. The method is based 
on the observation that estradiol, previously complexed with nuclear 
binding sites as a result of hormonal injection or ovarian secre- 
tions, is freely exchangeable with 3 H -estradiol during in vitro incuba- 
tions of the nuclear fraction. This technique has revealed that the 
injection of estradiol -17/? results in an increased number of 
nuclear receptors in the uterus, vagina and anterior pituitary but has 
no effect on kidney or muscle. In addition, the injection of estrogenic 
hormones, but not testosterone or progesterone results in increased 
quantities of nuclear binding sites in the immature uterus. Fluctua- 
tions in the quantities of nuclear binding of the uterus as a function 
of endogenous hormonal levels were also examined. In mature cycling 
rats, uterine nuclear receptor concentrations were: proestrus, 2.44; 
estrus, 0.58; metestrus, 0.42; and diestrus 1.42 pico moles/per 
milligram DNA. These data reveal a cyclic fluctuation of nuclear re- 
ceptor concentration which parallels the ovarian estrogen secreatory 
rate during the estrous cycle. 

Effects of Differentiated Brain on the Development of the Nervous 
System of the Explanted Chick Embryo. Abdulla Lairje and 
Norman A. Dial, Department of Life Sciences, Indiana State Univer- 
sity, Terre Haute, Indiana 42809. One theory of development sug- 
gests that differentiated tissue inhibits in some way the differentiation 
of the same type of tissue in the early embryo. Blastoderms of chick 
embryos incubated for 24 hours were explanted to an agar-albumin- 
glucose medium made up in Howard Ringer solution and further 
incubated in Petri dish moist chambers for a period of 12 to 24 hours. 
Small pieces of brain from 7-10 day incubated embryos were placed on 
the blastoderm near the developing brain of the explant or in small de- 
pressions in the medium under the anterior portion of the explant. 
Homogenized brain mixed in the medium was also used. As a control, 
chick leg muscle from 7-10 day incubated embryos was used in the same 
manner. Untreated controls were also used. Fifty-seven (40.7 per cent) 
of 140 explants treated with differentiated brain showed brain 
abnormalities, while 15 of 74 (20.3 per cent) muscle-treated controls 
showed such abnormalities. Twenty of 112 (17.9 per cent) untreated 
controls had brain abnormalities. The usual kinds of abnormal changes 
observed included rudimentary or absent optic vesicles, reduced size

and rounded or pear-shaped anterior neural structures. These mor- 
phological changes were limited primarily to the forebrain. 

Coccidial Immunity Studies In The Grey Squirrel 1 Thomas 
Joseph, Department of Biology, Indiana University at South Bend, 
South Bend, Indiana 46615. The response of the grey squirrel 
Sciurus carolinensis to infection with Eimeria lancasterensis and 
E. confusa was investigated. All 17 squirrels live-trapped from 
Tippecanoe County, Indiana, were naturally infected with E. lancaster- 
ensis. One of the squirrels carried a mixed infection with both 
parasites, but E. confusa disappeared after a week in captivity. The 
infection with E. lancasterensis persisted throughout captivity in all 
squirrels. This parasite infected the epithelial cells of the distal 
two-thirds of the villi. When experimentally inoculated with 
E. confusa, the squirrels took the infection with a patent period that 
ranged from 7-15 days. The patent period was shortened by repeating 
the infection; however, additional infections proved to be negative. 
Eimeria confusa infected the entire villus and penetrated deeper into 
the epithelial cells. The results of the study lead to the following tenta- 
tive conclusions: 1) Grey squirrels do not develop immunity to 
E. lancasterensis, but will become immune to E. confusa and remain 
so for a period greater than 5 months; 2) Repeated infections with an 
interval of 1 month do not produce immunity; 3) It appears that im- 
munity is more likely to develop against coccidia that penetrate deeper 
into the host tissues and may be a factor responsible for the low 
incidence of E. confusa in nature.

Relationship between Metabolic and Emergency Rhythms in Drosophila 
melanogaster. Karen Belcher, Department of Life Sciences, Indiana 

State University, Terre Haute, Indiana 47809. Oxygen consumption 

and lactic dehydrogenase (LDH) activity were measured to determine 
a metabolic rhythm and this rhythm was then compared with the 
emergency rhythm and the relationship determined. Oxygen consump- 
tion was determined for Drosophila melanogaster pupae that had been 
exposed to 12:12 or 1:23 light-dark (LD) regime and LDH 
activity was determined for pupae exposed to 12:12 LD regime. 

Bimodal circadian fluctuations of oxygen consumption were found 
to exist in pupae of D. melanogaster exposed to 12:12 or 1:23 LD 
regime. Pupae under both regimes appeared to demonstrate an 
anticipatory change in oxygen consumption associated with the change 
in illumination. Techniques employed in the study did not permit detec- 
tion of any regular fluctuations in LDH activity but a steady decrease in 
LDH activity during pupal development was evidenced. 

The oxygen-consumption trend for the entire pupal stage showed 
a high at the time of emergence, but the diurnal rhythm for oxygen 
consumption showed a low at the time of emergence. These data suggest 
that emergence occurs at a metabolic low in the diurnal cycle. 



342 Indiana Academy of Science 

Emergence data for the population showed an anticipatory change in 
the level of emergence to a change in illumination. A dark to light 
change was accompanied by an increase in number of emergents and 
a decrease in oxygen consumption. Emergence maximum showed a 
3-hour lead over the oxygen-consumption maximum. Changing the LD 
regime from 12:12 to 1:23 and changing the time of the 1 hour of light 
by 12 hours in the 1:23 LD regime produced similar changes in the phas- 
ing of both oxygen-consumption and emergence rhythms. 

Sites of Cell Proliferation in a Colonial Hydroid, Campanularia 
flexuosa. Robert L. Suddith, Department of Zoology, Indiana 

University, Bloomington, 47401. The colonial hydroids exhibit diverse 

and specific patterns which are generated during the normal growth 
of the colony. Analysis of these growth patterns requires an under- 
standing of the mode of growth. Morphological growth is expressed 
in the colonial hydroids as terminal elongation concomittant with an 
increase in colony mass (all hydroids) and pedicels (thecate hydroids). 
The sources of growth — primarily cell proliferation and secondarily 
increase in cell mass— have been thought to reside in the site of 
morphological elongation, the stolon tip, in a situation analogous to an 
apical meristem in plants. 

When bands of cells in an actively growing stolon are marked with 
nile blue sulfate, their movement does not correspond with that to be 
expected if cell proliferation is in the terminal region. We have 
undertaken a series of pulse-chase experiments using 3 H-thymidine 
as a marker to determine the site(s) of cell proliferation in an 
elongating stolon. Colonies were placed in filtered sea water containing 
3 H-thymidine at a concentration of 5 micro Curie per milliliter for 1 
hour and then incubated in filtered sea water containing 10~ 4 molar 
cold thymidine for one hour, before fixation. The tissue was fixed in 
Bouin's, embedded in Paraplast, and sectioned at 6 microns. The slides 
were coated with Kodak NTB-3 liquid nuclear tracking emulsion and ex- 
posed for 29 days. The developed slides were stained with Harris 
hematoxyline and counterstained with eosin. 

Detailed analysis of the position of labeled cells following the 1 
hour pulse with 3 H-thymidine reveals that only a few cells are 
labeled in the terminal 200 microns of the stolon tip. In the region 
0.5-1.0 millimeter behind the tip there is a high density of labeled 
cells; beyond this to a distance 2.4 millimeter behind the tip there are 
few labeled cells. This is in direct contrast to the concept of a restricted 
terminal cell proliferation region. Proliferation of cells elsewhere than 
at the stolon tip is compatible with the results of vital staining experi- 
ments of Hale, Crowell, Syttenbach, and Suddith. In the particular 
stolon studied, the region containing a high density of labeled 
cells is at the level at which a new hydranth would be expected to 
develop. 

Some Effects of Methylmercury on Early Frog Development. Norman 
A. Dial, Department of Life Sciences, Indiana State University, Terre 

Haute, Indiana 47809. Little is known of the effects of 

methylmercury on early embryonic development. Preliminary investiga- 



Zoology 343 

tions utilizing embryos of the frog (Rana pipiens) have been conducted. 
Embryos in various stages of early development were treated with 
various concentrations of methyl mercuric chloride in Holtfreters grow- 
ing solution. The extremes in concentration ranged from 0.2 to 200 parts 
per billion (ppb). Solutions were changed daily to maintain a relatively 
constant exposure to a given concentration. Duration of exposure ranged 
from 2 days at higher concentrations to 7 days at lower concentrations. 

Results indicated that selective developmental defects (poor tail 
development) may occur at concentrations as low as 1-5 ppb when 
treatment was begun in the late blastula and neural plate stages. Con- 
centrations of 80 ppb or more inhibited development altogether within 
36 to 48 hours when treatment was begun in early cleavage and late 
neural plate stages. A graded response as a result of time and concen- 
tration was evident. For example, midgastrula eggs treated with 
10 ppb methyl mercuric chloride resulted in stunted, irregular tails 
and a slight slowing of body development after 6 days of exposure. On 
the other hand, eggs treated at the 32-cell stage of cleavage with 20, 
40, 60, 80 and 100 ppb methyl mercuric chloride showed the following 
after 24 hours: Controls-late blastula-early gastrula; 20 ppb— same 
as controls; 40 ppb — same as controls; 60 ppb— mid-blastula ; 80 
ppb — mid-blastula ; 700 ppb early blastula. After 48 hours controls 
were in the neural plate stage, while the 20, 40, 60, 80 and 100 ppb 
treated groups showed the following: Complete dorsal lip, early dorsal 
lip, late blastula, mid-blastula and early blastula, respectively. No 
further development occurred in any of the treated groups while con- 
trols continued to develop normally. Further investigation is continuing 
to determine uptake, localization and whether or not stage tolerance 
exists.

seining collections, 44 1/2 hours were used in 111 AC electro- 
fishing collections, and 139 hours were used in 53 DC electro- 
fishing collections. Collections were made in all habitats during the 
months of May through November each year. 

The most frequently captured fish, based upon the per cent of 
collections containing at least one specimen, are as follows : 

Gizzard shad, Dorosoma cepedianum (69%); Carp, Cyprinus carpio 
(44%); River carpsucker, Carpiodes carpio (37%); Spotted bass,

Abstract 

Holstein and Holstein-Red Danish dairy calves were removed from their mothers with- 
in 30 minutes after birth and before nursing. Thirty-six calves were raised from birth 
until 18 weeks of age on 1 of 4 treatments: Group SS, fed individually-penned 
individually; Group ST, fed individually-penned in groups of three; Group TS, fed 
in group of three-penned individually; and Group TT, fed in groups of three- 
penned in groups of three. Animals were then maintained in one group on pasture until 
their first parturition. Subjects raised together were more vocal, ignored and did not 
protect their young, partially cleaned them and failed to allow nursing. Raised separately 
cows had few vocalizations, tended to fully clean, protected their calves and allowed 
nursing. At second calving all cows cleaned, nursed and protected their young. Those 
showing poor maternal behavior at first calving remained less efficient at second calving. 
There were no significant differences among the four gi'oups as measured by ease of train- 
ing to enter the milking parlor, frequency of kicking, temperament and milking ease. 

SS Holsteins (P<.05) produced more milk than those fed and raised under other 
conditions. The variance within groups was tripled as early feeding-rearing conditions 
progressed from SS to TT. 

Introduction 

Within the herd, several social hierarchies are known to develop 
which function to define priority rights to food and water and 
leadership for each animal. At least three (dominance, leadership and 
entrance order into milking parlors) and perhaps four (submission) 
are distinct social orders which evolve among cows. The observed social 
order is a function of the test situation. A submissive order which is 
the readiness of an animal to defer to an attacking animal is distinct 
from the dominance order of the provoking cow which wins. 
Donaldson (4) showed both the dominance and submission tendencies 
of dairy calves could be altered by manipulating early feeding and rear- 
ing conditions. Calves that were reared together in groups of three with 
limited feeding space, regardless of whether they were fed separately 
or with other calves, were significantly more dominant than calves 
reared separately. Calves that were fed together, regardless of their 
rearing condition were significantly more submissive than calves fed 
separately. Fed separate-reared separate calves were significantly less

dominant and less submissive than other calves while fed together- 
raised together calves were more dominant than calves from other 
feeding-rearing conditions. 

These same calves were available for later observations as cows 
to ascertain what effects early experience had upon later social and 
maternal behavior as well as milk producing capabilities. 

Methods 

The subjects in this study (5) were 18 Holstein-Friesian heifer 
calves and 18 Holstein-Friesian X Red Danish crossbred heifer calves. 
On the basis of birth order, the first nine calves born were assigned 
to a group (SS), the second nine were allotted to a second group, etc. 
until all subjects were assigned to one of four treatment conditions. 
The 36 calves were raised from birth until 18 weeks of age on one of 
the following four treatments : 

1) Group SS: fed separately—raised separately 

2) Group ST: fed separately — raised together 

3) Group TS: fed together— raised separately 

4) Group TT: fed together — raised together 

An attempt was made to remove the calves from their dams within 
30 minutes after birth and before they nursed. As a consequence of late 
night births, however, several calves were with their mothers for 4 or 
5 hours and they nursed at least once. Early removal from the dam may 
be an important point in this study, since J. P. Scott predicted 
earlier that if a group of calves were taken from their mothers at birth 
and put together they would form primary social relationships with 
each other (personal correspondence with T. H. Scott, 1956). Primary 
social relationships in some animals are formed within a matter of hours 
after birth (10). 

The calves were placed either individually into a 3 feet 
x 6 feet x 5 feet pen (0.9 m x 1.8 m x 1.5 m) or three 
calves lived together in a 6 feet x 12 feet x 5 feet pen 
(1.9 m x 2.6 m x 1.5 m). The pens provided isolation and were 
constructed of 3/8 inch (9.5 min) plywood within an unheated, lighted 
barn. Four 6 feet x 12 feet (1.8 m x 2.6 m) feeding pens were con- 
structed in the barn. One small 20 inch x 12 inch x 24 
inch (0.50 m x 0.30 m x 0.60 m) feeder was in each feeding 
pen. These feeding and rearing techniques are a departure from 
recommended procedures at Purdue. Individual calves are normally 
reared and fed in a 4 feet x 7 feet pen where they can see one another. 
Following weaning, they are in small groups of 4-8 calves for 
approximately 1-2 months after which they are taken out of doors and 
placed in a large group of 30 heifers. 

The subjects were fed a conventional powdered milk replacer, calf 
starter diet and a mixture of timothy and alfalfa hay. Water was 
available ad libitmn in the pens. After 18 weeks of age the heifers were 
maintained as a group on pasture until their first parturition.

was computed for each animal. The parturition sequence was observed 
through two calvings during which aspects of maternal behavior were 
recorded. The cows were rated on milking parlor behavior by two full- 
time milkers. Milk production was recorded daily and 4% fat-corrected, 
305 day lactation milk records were also compared for each group. 

Results and Discussion 

There were wide differences among cows in maternal behavior with 
their first calf. Raised-together cows ignored their young or partially 
cleaned them and failed to allow nursing. Raised-separately cows fully 
cleaned their offspring and allowed nursing. Raised-together cows 
tended not to protect their young and were quite vocal toward them 
while raised-separately cows were protective and did not make many 
vocalizations. A Chi-square test was performed for group differences 
in care and cleaning the calf. Values approached significance 
(P<.10) in that animals raised separately cleaned their calves 
better than those raised together. There were significant group differ- 
ences in nursing allowed within 4 hours after birth (P<.025) as well 
as in protection of the calf (P<.01) and approached significance in 
vocalization toward the calf (P<.10). 

With their second calf, all cows cleaned, nursed and protected their 
young, but there was a difference in the degree to which these be- 
haviors were performed. Cows that had not given proper care to their 
first calf were not nearly as maternal as those that had taken care of 
their first calf. It was concluded that early feeding and rearing 
experiences dramatically affect maternal behavior. 

It is not uncommon for cows to reject their young. Russian workers 
(1) support the claim that high milk-producing dairy cows and produc- 
tive hens are known to lose some degree of maternal instinct. Also, 
Selman and co-workers (11) in Scotland, under continuous observation 
of natural suckling in cattle (10 beef cows, 10 dairy cows and 10 dairy 
heifers) during the first 8 hours postpartum, found that teat sucking 
advances were rejected at some time by 15 of the 30 dams. These 
rejections consisted of either moving away from, or kicking at, their 
calves. However, in 13 of the 15 dams, rejections were seen only 
occasionally and usually occurred only when calves pushed vigorously 
at udders. This mild form of rejection inhibited only the weakest 
calves. When suckling eventually commenced, all 13 dams became very 
quiet. Two primiparous heifers rejected their calves' advances for 
6-8 hours. These two mothers frequently ran away from their calves. 

There was no statistically significant difference among the groups 
in milking parlor behavior as measured by the ease of training to enter 
the milking parlor initially and one month postpartum, as well as 



348

frequency of kicking, temperament and milking ease. While differences 
existed for other behavioral traits, one might expect milking parlor 
behavioral differences. However, this was not the case. The milking 
parlor quickly becomes a routine where defined behaviors are rewarded 
and all others are disciplined early and oftentimes changed. In 
addition, being milked and having udder pressure reduced is, in itself, 
rewarding and thus conducive to having a cow conform to the 
routine (3). 

The milk production records for each breed in each feeding-rearing 
condition are presented in Table 1, with SS Holsteins producing up to 
3,500 lbs more milk than other groups while, TT crossbreds average 
about 2,000 lbs more milk than other groups. With the exception of TS 
crossbreds, the standard deviation within groups increased as a function 
of increased "together" contact during early calfhood. For each breed 
the standard deviation is more than tripled as early feeding-rearing 
conditions progress from SS to TT. The TS crossbreds show the highest 
variance of all groups. Earlier, Donaldson (4) pointed out that the TS 
group (fed together — raised separately) was characterized by excessive 
amounts of non-nutritive sucking during their early experience, while 
other groups did not exhibit non-nutritive sucking after reaching 4 days 
of age. The only animals lost on this experiment were from group TS, 
one Holstein and one crossbred, who died at the age of 5 weeks.

Regarding milk production, assuming a fixed model with an 
unweighted mean, an analysis of variance was computed. A summary of 
this analysis in Table 2 shows a significant difference for the breed main 
effect (C) with Holsteins averaging more milk produced (12,061 lbs) 
than crossbreds (10,827 lbs) during the first lactation. This finding was 
not unexpected in that purebred Holsteins have been bred and main- 
tained for their high milk production. The crossbreds gave more milk 
than the smaller Red Danish, but still were not as large or capable of 
producing as much milk as the Holstein. 

Table 2 also reveals a significant interaction of feeding by breed. 
An examination of the data shows that the feeding condition affected 
the breeds differentially. For Holsteins the fed-separate Holsteins av- 
eraged 13,158 lbs of milk while fed-together Holsteins averaged 10,964 
lbs of milk. On the other hand, for crossbreds, the fed-together condi-

tion was more conducive to higher milk production. Fed-together cross- 
breds averaged 11,353 lbs of milk while fed-separate crossbreds 
averaged about 1,000 lbs less (10,301 lbs) of milk. By chance, higher- 
quality dams were used to produce the crossbred calves that filled the 
fed-together groups. They averaged 13,177 lbs of milk while the 
fed-separate calves came from dams averaging 10,800 lbs of milk. 

By combining the data (ABC interaction, P<.08) it appears that 
certain conditions maximize milk production for Holsteins as well as 
for crossbreds. 

Cows that experienced competitive raising had a higher average 
Social Index and were more domineering and aggressive within a herd 
and rejected their young at first parturition. Cows that were raised in- 
dividually tended to be low ranking in the herd and accepted their young 
at first parturition. 

The importance of "contact comfort" has been demonstrated for 
dogs (8, 9) and for monkeys (7). Presumably, in the absence of any type 
of species interaction, the SS group developed and maintained a high 
drive for contact which could be most fully expressed when their calves 
were born. If this is true, one would expect cows that have been raised 
individually to actively seek more contact within the herd and to main- 
tain closer physical proximity to other animals than cows raised 
together. Unfortunately, such data are not available. 

On the other hand, three of the groups had enriching, almost to 
the point of stressing, experiences in their competition for food and 
living space. The competitive animals experienced, in effect, an over- 
exaggeration of a learned behavior pattern with the ultimate effect of 
enhancing the frequency and efficiency of that behavior pattern. 

Given that the competitive groups were inclined toward emotional 
disturbances due to maternal deprivation, while at the same time were 
prone to overreact with aggressiveness due to early experience, one can 
readily expect rejection of the young. Later, when other experiences 
had altered the effect of early experience, the second calf was accepted. 
In a similar hypothesis, Bronfenbrenner (2) proposes the "frustration 
of dependency drive" when mother-infant interactions are absent and 



350 Indiana Academy of Science 

specifically predicts "initial fear, rejection of, and aggressiveness 
toward other social objects." 

An alternative theory would be to ignore any deprivation during 
the first 4 months and focus mainly upon the agonistic experience. Cows 
from the competitive groups had been conditioned since the first day 
of their lives to be constantly perceptive of social threat. Not sur- 
prisingly they treated their first calf as another animal and only after 
experiencing the non-threatening aspects of the situation could they 
accept the second. Conversely, the raised-individually group did not 
perceive or respond to threat from other cows and subsequently were 
able to exhibit the full range of maternal behavior correctly the first 
time. 

It would be interesting to know how early feeding and rearing 
experiences affect other breeds of cattle and then investigate the 
economic feasibility of rearing each breed in a condition that be- 
haviorally and physiologically promotes milk production. Since twin 
calves are known to stay together (6), an obvious experiment is to rear 
twins apart from each other. They would have to be separated very early 
as the primary social relationships are formed within a matter of hours, 
i.e., sheep and goats (10). It would be very interesting to see if the twins, 
when brought back together, would tend to stay together and imitate 
or mimic their behavior as they ordinarily do. The close behavioral 
link between twins reared together at present tends to increase the re- 
semblance between twins in such items as grazing behavior and milk 
production.

Space and Conflict in Cattle 1

Abstract 

Agonistic behavior is more pronounced among cattle when they are closely confined 
in yards or holding areas. Many authors have collected data on social behavior 
(dominance and temperament) under these conditions rather than when little agonistic 
behavior is occuring such as when cows are on pasture (1, 2, 3). Sommer (7) has reviewed 
the literature regarding dominance relationships in which a subject knows where he 
belongs socially, and territorially with his knowledge of a spatial place. Macmillan (5) 
reported that reduced fertility and short estrus cycles in young cows were the result of 
social stress in large herds of 200 or more cows in one group. Kilgour (4) suggested that 
in closely confined areas, the existence of the social order causes stress to the cows low 
in the dominance order in that they must constantly violate the space of higher ranking 
animals and they are attacked. 

The purpose of the present study was to determine the amount of agonistic behavior 
and movement that occurs among animals in relation to rank when the size of available 
space is changed. 

Method 

Ten yearling Holstein heifers that weighed between 790 and 1,025 
lbs were chosen randomly from a group of 25 maintained under summer 
pasturing conditions at the Purdue Dairy Center, Cherry Lane, West 
Lafayette, Indiana. The subjects were then confined in a 40 feet x 25 
feet electric fence holding area. Adequate feed bunk space (3 feet x 16 
feet) and a watering trough were at one end of the holding area. 

The heifers were given 3 days to adjust to the holding area and 
then were observed 4 hours per day for the next 3 days to determine 
the social dominance hierarchy within the group, using the technique 
of Schein and Fohrman (6). 

The holding area was lined at 5-foot intervals with a 2-inch strip 
of powdered lime with the result that the holding area was marked off 
into 5-foot squares (approximately the heifer's length of body). 

One end of the fence was movable so that the size of the holding 
area could be adjusted by the experimenters. 

Heifers were observed for 16 one-half hour periods for the next 
2 days. Four observations were made under each of four sizes of the 
holding area: 40 feet x 25 feet, 30 feet x 25 feet, 20 feet x 25 feet

and 10 feet x 25 feet. These areas were considered to be 100, 75, 50 and 
25%, respectively, of the recommended routine pen size allocation for 
yearling heifers. The order of size changes were reversed with each 
successive observation. 

During the observational periods, all agonistic behavior was 
recorded and the dominance order was redetermined using the technique 
of Schein and Fohrman (6). Also recorded was the number of squares 
that each subject entered. A heifer was required to put both front feet 
in a square to be counted as entering that space. 

The dominance order was compared with the one determined pre- 
viously. Data were then analyzed by means of an analysis of variance. 

Results and Discussion 

Assuming a fixed model, an analysis of variance was computed on 
the obtained scores in Table 1. A summary of this analysis in Table 2 
shows significant differences for both field size and subjects 
(P<.01) in that the three low ranking animals entered the most squares, 
averaging 1,044, and the five middle animals entered the least 
squares (469). As had been predicted by Kilgour (4), low ranking 
animals were observed to be constantly violating the space of other 
animals and were moving to prevent or avoid being attacked. 
Surprisingly though, high ranking heifers entered an average of 215 
more squares than middle ranking animals. In the smallest enclosure 
(10 feet x 25 feet) it appeared that high ranking animals followed the 
escaping low ranking subjects. Subjects in the reduced space showed 
less total activity (P<.01).

Movement can be categorized as another indication of dominance. 
The behavior and status of animals moving from one area to another 
area was remarkably similar. 

Considerable movement, conflict, competition and agonistic behavior 
occurred near the feed bunk. This is similar to earlier work with 
heifers (1, 3) and with cows (2).

A Check List of Freshwater Ostracods of Indiana — 

Including Sixteen New Recordings 

and a Description of Two New Species 

Daniel R. Goins 

Daleville High School, Daleville, Indiana 47334 

Abstract 

The check list of freshwater ostracods of Indiana raises the number of ostracods re- 
ported from Indiana from 6 to 24. The list is a result of a survey taken in the spring of 
1968 in Delaware County. The list includes the descriptions of 2 new species: 
Potamocypris brachychaeta and Candona ginnensis. 

Introduction 

A survey of ostracods (Class Crustacea, Order Ostracoda) was 
taken through Delaware County during May and June, 1968. The survey 
was an attempt to fill a gap in the taxonomy of ostracods from 
Indiana. Comprehensive surveys of ostracod faunas have been made 
in Ohio (1) and Illinois (3), but to date none have been made in 
Indiana. There are scattered reports of ostracods from Indiana; among 
these are 4 cave types; Candona marengoensis, C. jeanneli (5), 
Entocythere donaldsonensis (7), E. barri (2). There are only 2 
ostracod species reported from streams and ponds in Indiana: 
Cyiiridojjsis vidua (4), Cyclocypris laevis (6). The survey of Delaware 
County raises the number of known ostracods from Indiana from 6 to 
24 including 2 new species. 

Methods and Materials 

During May and June 1968, 100 dredge-net samples were taken 
in Delaware County. The samples were taken from rivers, creeks, ponds, 
drainage ditches, and borrow pits. Of the 100 samples 62 contained 
ostracods. The ostracods were preserved in a 95% alcohol solution. 
Permanent reference slides were made and placed on file in the Ball 
State University biology laboratory. 

Description of New Species 

Potamocypris brachychaeta, sp. nov. 

Five specimens were collected from two sample sites. 

Sample number 20 was from a borrow pit along Interstate 69 in Delaware County. 
The pit is about 6 acres in area and the true depth is not known. The bottom is mostly 
mud and silt. There was little vegetation except along the edges of the pit, and this was 
mostly grass and unidentified algae. Cypridopsis vidua was also found in the sample. 

Sample 31 was taken from a small creek with slow movement under normal 
conditions. The bottom was mostly silt and much decaying vegetation. The water was clear. 
Five other species of ostracods were found at this site: Ilyocypris bradyi, Candona 
elliptica, Candona sp., Paracandona sp., and Darwinula stevensoni. Also found in the 
collection were many unidentified insect larvae, copepods, and cladocera. 

Potamocypris brachychaeta is easily identified as genus Potamocypris because of the 
genus characteristics: reniform shape, compressed valves, arched dorsum maximum height

reached at mid-length, broad anterior vestibule, with the left valve slightly overlapping 
the right valve. The valves of P. brachychaeta are punctate with very few hairs and are 
grayish with several areas of green pigment. The pore canals are simple and the hinge 
is adont. This new species differs from the other potamocyprids with abbreviated natatory 
setae in that the setae of P. brachychaeta are very short (Fig. 6). The swimming setae 
are a mere 0.08 mm long and barely reach the proximal 1/3 of the penultimate segment. 
Another distinguishing feature is the appearance of a second posterior list on the left 
valve ( Fig. 1 ) . This list does not appear on any of the other species of 
Potamocypris. 

Dimension of adult female: Right valve 0.56 mm long, 0.29 mm high. Left valve 
0.59 mm long, 0.36 mm high. Width 0.3 mm. 

Candona ginnensis, sp. nov. 

The sample was collected from Ginn's Woods, a preserve of Ball State University in 
Delaware County, Indiana. Five individuals were found in a sample taken in April. The 
sample contained Candona truncata and the eggs of the spring peeper, Hyla 
crucifer, and the chorus frog, Pseudacris nigrita. 

The left valve of Candona ginnensis is slightly longer and higher than the right valve. 
The greatest height is reached in the posterior one-third of the valve. From the rounded 
anterior, the dorsal margin arches gradually to the maximum height. Posteriorly the 
dorsal arch curves gently to the posterior; this downward curve is not sharp as in 
Candona truncata. From the broadly rounded posterior margin the ventral margin forms 
a slight sinuation at the mid-point. The male has a weak point where the ventral margin 
meets the anterior margin. The third leg has an undivided penultimate segment. The 
prehensile palps are both similar with a double row of teeth on the ventral side at the 
curve between the setae (Figs. 12, 13). The furca has a definite "S" shape in the 
female (Fig. 15) and is only slightly less pronounced in the male. 

Dimensions of adult female: Right valve 0.85 mm long, 0.42 mm high. Left valve 0.93 
mm long, 0.45 mm high. Width about 0.5 mm. 

Dimensions of adult male: Right valve 1.1 mm long, 0.5 mm high. Left valve 1.2 mm 
long, 0.6 mm high. Width not determined. 

Candona ginnensis is similar to Candona simpsoni (Sharp, 1897) and C. 
sigmoides (Sharp, 1897) (6) with each having an S-shaped furca. However, the valves 
of Candona ginnensis and C. sigmoides are arching, while the valves of C. 
simpsoni are elliptical in shape. The sizes also differ with Candona ginnensis 
being between C. simpsoni, the smallest, and C. sigmoides, the largest. The penis of C. 
ginnensis (Fig. 16) is longer and somewhat narrower than the penis of C. sigmoides. The 
genital lobe (Fig. 11) of the female of the new species is shorter and less pointed than 
that of C. sigmoides.

Parasites of the Bullfrog in Indiana 1 

Doyal R. Lank, Jr. 

Department of Biology 

Ball State University, Muncie, Indiana 47306 

Abstract 

Parasitological examinations were made of 72 bullfrogs from four Indiana areas 
during May through September 1970, of which 91.7 per cent contained parasites. 
Parasites found included: (protozoans) Hexamita intestinalis, Nyctotherus cordiformis, 
Trypanosoma rotatorum, and an unidentified species of Trichomonas; (trematodes) 
Gorgodcra amplicava, Gorgoderina attenuata, Haematoloechus brevij)lexus, Haemato- 
loechus longiplexus, and Glypthelmins quieta; and (nematodes) Cxysomatium longi- 
caudata and one unidentified species. Two species of Hirundinae, Placobdella rugosa 
and Glossiphonia stagnalis, were found apparently as parasites. 

Introduction 

Brandt (2), in a comprehensive study of the parasites of several 
species of North Carolina frogs, has presented the only extensive review 
of the parasites of bullfrogs, Rana catesbeiana Shaw. He found the bull- 
frog to harbor a number of helminth and protozoan parasites and one 
arthropod. Reports of parasites of bullfrogs in Indiana are few. Cort 
(5) observed the lung flukes Haematoloechus longiplexus and H. 
breviplexus from a North Judson, Indiana, bullfrog, and Walton (21) 
found cysts of the nematode Physaloptera ranae in the stomach and 
intestinal walls in bullfrogs of northern Indiana. Krull (11) also found 
H. longiplexus in an Indiana bullfrog. More recently, Myer (17) reported 
metacercariae of the fluke Mesostephanus kentuckiensis in Ohio bull- 
frogs. Since Cable (3) reported cercariae of M. kentuckiensis in snails 
from McCormick's Creek and Clifty Creek, Indiana, this trematode may 
occur in Indiana bullfrogs, although none has yet been reported. 

Materials and Methods 

The bullfrogs examined in this study were collected from four 
Indiana Fish and Game Areas: Glendale, in southwestern Indiana 
(Daviess County), Crosley Lake in the southeast (Jennings County), 
Willow Slough in the northwest (Newton County), and Tri-County in 
the northeast (Kosciusko and Noble Counties). Frogs were collected 
at night by hand or by a dip net. 

Five monthly collections were made at each of the four study areas. 
The frogs were taken to the laboratory at Ball State University and 
placed in a refrigerator until examined. Some frogs were dissected and 
searched for parasites within 24 hours after collection, but others were 
held for as long as 10 days before examination.

Before examination the bullfrogs were either pithed or beheaded. 
The heart, lungs, stomach, large and small intestines, cloaca, liver, gall 
bladder, kidneys, and urinary bladder were examined. Before removing 
the organs, the host was searched for any coelomic parasites, using a 
dissecting microscope. Upon removal, each organ was placed individually 
in frog Ringer's Solution in a watch glass in order to retain any para- 
sites which might leave the organ. 

Each organ was then opened or teased apart under a binocular 
dissecting microscope. Except for protozoans, all parasites found were 
counted and representatives preserved for permanent mounting. Smears 
were made of the contents of the intestines and of peripheral, renal, 
and cardiac blood for examination under a compound microscope. 

Blood smears were made by using Wright's stain or by fixing in 
95% alcohol and staining with Giemsa's stain. Intestinal smears were 
fixed in Schaudinn's fluid and stained with Heidenhein's iron 
haematoxylin. 

All worms were washed thoroughly in physiological saline before 
fixing. Trematodes were relaxed in distilled water and then fixed in 
either 10% formalin, formol-acetic-alcohol (F.A.A.), or Bouin's solution 
which had been heated to bubbling but not vigorous boiling. 
Nematodes were dropped into warm F.A.A., 10% formalin, or 70% 
acid-alcohol for fixation. Leeches were fixed in 70% alcohol using the 
method described by Mann (14). For permanent storage, all worms 
were transferred to either 70% alcohol plus 5% glycerine or 
5% formalin plus enough glycerin to make a 5% solution, depending upon 
the method of fixation used. 

Stains used for trematodes and nematodes included Grenacher's 
Alcoholic Borax-Carmine, Mayer's MCI Carmine, either with or without 
Fast Green counterstaining, and Harris' or Delafield's Haematoxylin. 
After staining, the specimens were destained, dehydrated, cleared, and 
mounted in Permount. 

Cort (4, 5), Harwood (8), Higgins (9), Kudo (12, 13), Mann (14), 
Miller (16), Miller (15), Najarian (18), and Yamaguti (23) were used 
for making identifications. 

Results 

Seventy-two bullfrogs were examined for parasites between May 
and September of 1970, 20 each from Glendale and Crosley Lake and 
16 each from Willow Slough and Tri-County. Those frogs 100 mm or 
more in snout-vent length were classed as adult, and those below 100 
mm were considered juveniles. According to Wright and Wright (22), 
100 mm is approximately the minimum breeding size. The range of 
length of the 49 adult frogs examined was 100 mm to 142 mm, with 
an average length of 115.6 mm. The 23 juveniles ranged from 47 mm 
to 77 mm, the average being 62 mm. 

Of the 72 bullfrogs examined, 91.7% were found to be infested by 
one or more species of parasites (Table 1). Four species of protozoans

were found: Hexamita intestinalis, Nyctotherus cordiformis, Trypano- 
soma rotatorum, and an unidentified Trichomonas sp. Trematodes in- 
cluded the bladder flukes Gorgodera amplicava (3.817) 2 and 
Gorgoderina attenuata (0.772), the lung flukes Haematoloechus 
breviplexus (0.780) and H. longiplexus (0.793), and the intestinal fluke 
Glypthelmins quieta (1.913). The nematodes found were Oxysomatium 
longicaudata (2.822) and one unidentified species. No cestodes or 
acanthocephalans were encountered. 

Two species of leeches, Placobdella rugosa and Glossiphonia 
stagnalis, were found in the collecting jars, but were never seen 
attached to the frogs. Probably the leeches were on the frogs at the time 
of collection. 

Discussion 

In addition to the primary species-specific limitations, many fac- 
tors influence the kinds and numbers of parasites in a host: age, 
geographic distribution, diet, the presence of suitable intermediate hosts, 
seasonal aspects of the life cycle, etc. The operation of some of these 
factors as they apply to parasitism in the bullfrog has been reported 
by other authors, and data from the present study suggest the operation 
of others. For example, bullfrogs were introduced into the Rocky Moun- 
tain region relatively recently, but their parasites do not yet seem to 
be well established there (20). This may well be due to the absence of 
suitable intermediate hosts. 

Although the samples are small, the data in Table 1 suggest some 
seasonal variation in the abundance of parasites, most species showing 
peaks of occurrence in June, July, or August. Leeches were most 
abundant in June and July, and the recording of trypanosomes only in 
these 2 months may well be related to the abundance of the leeches, their 
possible intermediate hosts. 

Although most parasites were found in all four collecting areas 
(Table 1), there were two possibly significant exceptions. The blood 
protozoan, Trypanosoma rotatorum, was found in only the two northern 
collecting areas. This may again be due to the presence in these areas 
of large numbers of leeches. Leeches have been reported as intermediate 
hosts of trypanosomes in certain other amphibians: Trypanosoma 
diemyctyli in the Red-spotted Newt, Notopthalamus viridescens (1), and 
in various European frogs (6). 

The other exception is the lung fluke Haematoloechus longiplexus, 
which was found only in the two southern areas. 

With respect to adult frogs versus juveniles, only in two species 
of parasites is there a notable difference in the overall amount of in- 
festation. Hexamita intestinalis was found more often in juvenile bull- 
frogs than in adults (86.9% incidence compared to 69.5%). The

bladder fluke, Gorgoderina attenuata, was found in over half (53.1%) 
of the adult frogs, but in very few of the smaller frogs (13%). 

Multiple infestation in bullfrogs is a common occurrence and has 
been reported by Cort (5), Miller (15), and Najarian (18). In this study, 
some individual frogs contained six different species of parasites: three 
of the four protozoans and three of the five trematodes, although a 
typical frog would harbor one or two species of protozoans and a 
species of fluke. 

Two species of leeches, Placobdella rugosa and Glossiphonia 
stagnalis, are here reported for the first time as parasites of bullfrogs.

Distribution of Free-living Soil Nematodes of the 
Belondiroidea in Indiana and the United States 1

Abstract 

During a 5-year study of distribution of soil and fresh-water nematode species in 
Indiana, four genera of the Belondiroidea have been found widely distributed in natural 
areas of the state. Of these, Dorylaimellus Cobb, Axonchium Cobb, and Oxydirus 
Thorne were found in most biotic units of the state. In subsequent sampling in widely sep- 
arated areas of the U. S., Dorylaimellus and Axonchium were found in natural areas in 
all sections of the country sampled. Species of Oxydirus were found less frequently and 
appeared in only one collection in western U. S., a forest meadow in Sequoia National 
Park, California. Although four species of Belondira Thorne were well-distributed in 
southern Indiana, only two were found as far north as Tippecanoe County. Despite 
extensive sampling throughout the U. S. we have recovered specimens of this genus from 
a very limited geographic area, extending only from eastern Kansas to Tennessee. 

Introduction 

The nematode superfamily Belondiroidea as presently understood 
by most authorities consists of eight families and 13 genera (3). Of 
these, only five genera, one in each of five families, have been reported 
from continental United States : Dorylaimellus Cobb in the Dory- 
laimellidae; Axonchium, Cobb in the Axonchiidae; Oxydirus Thorne in 
the Oxydiridae; Belondira Thorne in the Belondiridae; and Swangeria 
Thorne in the Swangeriidae. All contain stylet-bearing soil species 
whose food habits are largely unknown. Some may be plant parasitic, 
although they are not generally found in large numbers around 
cultivated plants at least in temperate regions. For this reason they 
have been studied very little. 

Dorylaimellus virginianus Cobb was originally found by Cobb (2) 
in Virginia and subsequently also in Utah by Thorne (8). Other species 
of Dorylaimellus were found by Thorne (8) and Cobb (2) in 
Virginia, Idaho, Utah, Texas, and Colorado; and by Orr and 
Dickerson (7) in Kansas. A wide distribution for species of 
Axonchium was recorded by Thorne (8) when he reported their occur- 
rence in Utah, Colorado, Missouri, Washington, D. C, Georgia, South 
Carolina, and Florida. More recent collections were noted by Orr and 
Dickerson (7) in Kansas and by Hechler (5) in Virginia. 
Oxydirus spp. were reported from Utah and Virginia by Thorne (8), 
and Hechler (4) reported finding Oxydirus gangeticus Siddiqi in Mary- 
land. A single species of Belondira (B. apitica Thorne) was found by 
Thorne (8) in Utah, and this species plus another were found by Orr

and Dickerson (7) in Kansas. Swangeria bisexualis Hopper was 
described (6) from a series of 10 specimens taken in Florida. 

Despite the fact that the occurrence of belondiroid nematodes in 
the U. S. has been infrequently noted by nematologists, we found four 
of the five genera discussed above to be common in Indiana. Subsequent 
sampling over the rest of the country indicated that these four genera 
differ from each other in their biogeography. The present report con- 
cerns the distribution of genera only. Detailed studies of the species 
found within each genus will follow in later papers. 

Methods 

Intensive sampling of natural sites within the biotic units of Indiana 
(1) was carried out over a 5-year period. Sites were usually wooded 
and often included a stream or river. The number of samples taken at 
any given time from a specified area varied from 6 to 50, but most areas 
were sampled several times at different seasons of the year. Three 
3-liter samples were collected from each site. One sample was collected 
from the edge of the stream or river using a 2.5 cm sampling tube thrust 
15-20 cm into the soil, whenever possible. Approximately 50 such cores 
were collected for a distance of 30 m along the contour of the stream. 
A second such sample was taken from the normal flood plain, but away 
from the stream edge; and a third sample was taken well outside the 
normal flood plain. Additional samples were taken in specialized and 
typical habitats in all areas. Detailed ecological data were recorded at 
the time of sampling including information about flora of the area, soil 
type, soil contour, soil moisture, and other factors. Samples from other 
parts of the United States were collected in a manner similar to that 
used for Indiana samples. 

In the laboratory one 1-liter subsample was processed from each 
sample by a combination of sieves and Baermann funnels. Nematodes 
were relaxed by gentle heat (57°C for 10 min.) and killed and fixed 
in F. A. A. (9). A "profile" of all species present was established for 
each sample and the specimens processed to permanent glycerine mounts 
by the Thorne slow method (9). 

Results and Discussion 

The occurrence of representatives of these four genera in our collec- 
tions is shown on the maps, Figure 1 (Indiana) and Figure 2 (the 
U. S.). Dorylaimellus species are common throughout Indiana and are 
present in all areas of the U. S. we have sampled. The same generali- 
zation may be made about Axonchium, although it should be noted that 
we have recovered fewer species of Axonchium than of Dorylaimellus 
(3). Nematodes belonging to the genus Oxydirus are found in all parts 
of Indiana, although they were less numerous than nematodes of the 
former two genera. Oxydirus specimens appeared in only one collection 
in western U. S., a forest meadow in Sequoia National Park, California.

Although four species of Belondira are well-distributed in the southern 
part of Indiana, only two species were found as far north as Tippecanoe 
County. Despite a vigorous search for representatives of this genus 
throughout the U. S., we have recovered specimens from a very limited 
geographic area, extending only from eastern Kansas to Tennessee.

Conclusions 



Although members of the Belondiroidea have never been reported 
from many areas of the new world, it appears that the genera 
Dorylaimellus and Axonchium are widely distributed and common 
throughout the U. S. Oxydirus appears to be less widely distributed, 
especially in the western states, and the genus Belondira appears to 
be restricted in distribution.

The Woodrat in Indiana: Recent Fossils 

Ronald L. Richards

Indianapolis, Indiana 46201 

Abstract 

Skeletal remains of Neotoma, presumably N. floridana magister, have been recovered 
in relative abundance from caves throughout Indiana's karst area associated with bones 
of such locally extinct fauna as black bear, porcupine, elk, and spotted skunk. Presently 
rare in Indiana, a few woodrats have been historically recorded and recently observed 
marginal to the Ohio River. The ancient depopulation may have been associated with some 
indirect effect of climatic change. 

One species and several races of woodrat are present in the Eastern 
United States (4). Only a few woodrats, Neotoma floridana magister, 
have been recorded in Indiana (7), along and near the bluffs of the Ohio

woodrats in the two caves near the Ohio River where Hickie and 
Harrison first recorded them in 1930 (5). 

Kirkpatrick and Conaway found woodrat nests, though no rats, 
in Stroud cave, Orange County (6). Bader and Hall (1) found remains 
of woodrat in Sullivan's cave, Lawrence County, associated with bones 
of Didelphis marsupialis, Blarina brevicauda, Erethizon dorsatum, 
Sylvilagus floridanus, Spilogale putorius, Procyon lotor, Urocyon 
cinereoargenteus, Odocoileus virginianus, Cervus canadensis, and 
Myotis sp., again indicating an ancient distribution father north than 
at present.

and Hall (1). Several other nests in the cave. 

A nest with large Ursus bones and one Neo- 
toma. Five Neotoma were contemporaneously 
associated with Ursus, Spilogale, and Didel- 
phis in a carbon-rich area overlain by a 
sterile silt-clay layer. 

One Neotoma with Erethizon, among several 
nests. 

One Neotoma in an osteiferous, fissure in- 
washed silt deposit. A Spilogale dentary near- 
by was not necessarily associated.

From Indiana's caves have recently come numerous "Recent fossils" 
of Neotoma (Table 1), some as far north as western Monroe county 
(Fig. 1), and many with extensive associated faunas (Tables 2 and 3). 



Discussion 

Neotoma distribution in the past was most likely concurrent with 
the limits of both of Indiana's karst areas, according with its cave and

bluff crevice habitat. Nests were observed in the wall solution 
anastomoses, in fissures, crevices, on ledges, and in breakdown 
piles; Neotoma bones, however, occurred in many depositional situa- 
tions. Nests seem to have been used over again by successive woodrats. 
With time, the vegetal materials of the nest disintegrate, concentrating 
the bones, rocks, snails, etc., emphasizing the faunal component, where- 
as in all actively inhabited nests observed by the author in Kentucky 
the floral component had hundreds of times more bulk. Thus, the older 
nests usually had the greater bone concentration. The floral contents 
of nests have yet to be studied. Of the faunal contents, only those bones 
actually chewed upon can be attributed to the woodrat's collecting 
behavior, these being most all of the larger than squirrel-sized forms, 
with deer bones often making up the bulk. The extensive microfaunal 
remains were predominantly those animals inhabiting the cave (e.g.,

mice, shrews, bats, salamanders) or trapped in it (e.g., toads, frogs, 
snakes) and attracted to the nest, as indicated by the completeness of 
their skeletons, lured by the numerous invertebrates infesting its 
organic contents. Dying bats probably fell into the nests from their 
roosts. The minute clams and crayfish remains seem to be unique to the 
nests, perhaps collected by the woodrats, though along with the fish, 
could also been in the stomachs of raccoons, snakes, etc. Thus, many 
of the forms from the nests probably post-date the Neotoma, 
being only pene-contemporaneous. Animals associated in the sedi- 
mentary deposits, however, were most likely contemporaneous. Except- 
ing Spilogale, Ursus, Erethizon, and Cervus the associated fauna seems 
to be similar to that at present, the latter three exterminated from 
southern Indiana by the mid-1800's, and Spilogale with an ancient 
northerly distribution, much as Neotoma. This Neotoma-Ursus- 



374 Indiana Academy of Science 

Erethizon-Spilogale component commonly occurs together, and can be 
used locally to recognize a Prehistoric fauna. From faunal evidence the 
Neotoma archaeo-range seems to have been presettlement at minimum, 
and post-Pliestocene by the lack of true fossil fauna. The presence of 
Didelphis, known to be a late arrival in the Eastern United 
States (3), sealed in the Carcass Crypt sediments confirms a maximum 
of at least a few thousand years for at least that deposit. 

Illinois and Missouri also have "Recent fossil" finds. Jerry Long 
cave, Ralls County, Missouri, included a large percentage of Neotoma, 
Marmota monax, Ursus americanus, Sylvilagus floridanus, and Spilo- 
gale sp., among others. The bones were thought to have accumulated 
"a few hundred years prior to about 1850". Neotoma may inhabit that 
same area presently, but in less abundance (10). In Meyer cave, Monroe 
County, Illinois, bones of 535 Neotoma were associated with one of the 
most extensive Recent age faunas ever recovered in the United States, 
and included Spilogale and Erethizon where they do not presently occur. 
Neotoma was there 50 miles northwest of its living population (11). 
Spilogale has been recorded from the Modoc Rock Shelter, Randolph 
County, Illinois, where it does not presently occur, from a level radio- 
carbon dated at between 4,500 and 2,500 years B.D. (9). Other than the 
"Recent fossil" finds of Bader and Hall (1) and the author, 
Spilogale has not been definitely recorded in Indiana, paralleling the 
Illinois situation. 

Significantly, by Recent fossil evidence from three Midwest states 
Neotoma has had a distribution much farther north than at present, 
in Indiana almost 70 miles from the historically recorded Wayndotte 
Neotoma. The distance of the range delineation, age of the Illinois 
Spilogale, inferred ages of other Neotoma, and association with 
Didelphis permits a generalized age of a few thousand years, with a 
wide age span between northerly and southerly sites, to be inferred. 

There is a general opinion that following the glaciations climate 
has changed from cool to warmer than present, and now cooler again. 
During this warm phase prairies are thought to have expanded east- 
erly, and southern elements northerly (12). Parmalee (11), on the 
Meyer cave remains, regards Erethizon and several other northern 
forms as belonging to the cool-moist climate of approximately 9,500- 
7,500 B.C., and Spilogale and others as belonging to the warm-dry 
period of approximately 3,500-1,500 B.C. These forms, including the 
woodrat, were regarded as becoming expatriated, being unable to adjust 
to a replacement in vegetation type. 

As Neotoma floridana magister ranges almost abruptly to the 
southern borders of Indiana at the Ohio River, yet also ranges up 
through the cooler Appalachian area, temperature would not seem to 
play a strong role locally in its distribution. South-central Indiana's 
vegetation is similar, if not identical, to that of adjacent Kentucky, 
where Neotoma is common. Except for the Ohio River the karst 
habitat is continuous. Thus, Neotoma could probably inhabit Indiana's 
karst area today. The author holds that there was a widespread, and 



Zoology 375 

effective (i.e., lack of disjunct colonies) depopulation of Neotoma in the 
northerly portion of its range, rather than just an ancient northerly 
extension, and that with time Neotoma would regain its former distribu- 
tion were it not hampered by its slow immigration (e.g., from cave system 
to cave system, the Ohio River crossing). The widespread nature of the 
depopulation would seem to point to climate as the cause; however, with 
the ecological plasticity of Neotoma only an extreme in climate would 
seem to displace it. The associated fauna indicates that climate was not 
then at an extreme. Thus, some other ecological factor, perhaps an 
indirect result of a mild climatic change, would seem to be the cause 
of the Neotoma depopulation.

Abstract 

A total of 1,907 bats from Indiana was examined, of which over half were big brown 
bats, Eptesicus fuscus, a species which was found to be somewhat active all winter. Most 
other species were found primarily during April through October. Some Lasiurtis 
cinereus appear to hibernate in Indiana. Reproductive information for Pipistrellus 
subflavus and Eptesicus fuscus is presented. Most Eptesicus had two embryos. Parturition 
in this species occurs around June 1 in Indiana. Testis size in Eptesicus was 
greatest in August, but at least some individuals appear capable of breeding much of the 
year. Lasiurus borealis produced young about mid-June; juvenile red bats tend to leave 
their mothers when about 80 millimeters total length and they weigh about 4 to 6 
grams. A number of new county distribution records are included in this paper. 

Introduction 

This paper presents information on seasonal occurrence, reproduc- 
tion and growth, and distribution for 10 of the 12 species of bats 
recorded from Indiana (Table 1). These data were collected mostly from 
1963 to 1971 during our investigations of Indiana mammals (11, 12, 14, 
15, 21). The bats examined were obtained from several sources. Some 
were shot about wooded or water areas or collected from buildings and 
caves. Many were collected by citizens of various areas and submitted

Results 

A total of 1,907 bats from Indiana was examined during the present 
study (Table 1). More than half (1,126) were big brown bats, Eptesicus 
fuscus, which might indicate this as the most common bat in the state. 
However, since Eptesicus is active during the winter, while 
Lasiurus borealis is not, the months May to September were used for 
comparison. During those months 811 big brown bats and 437 red bats 
were taken. Since Eptesicus is the common bat in buildings, perhaps 
citizens are more apt to encounter it than other species. Also, the total 
for Eptesicus is inflated by a few collections of numbers of bats from 
buildings, 133 from Madison during rabies studies (22) and several other 
smaller collections. Red bats are solitary and cannot be collected by such 
methods. We can conclude that these are the two most common bats 
in Indiana. 

Next in abundance would appear to be Myotis lucifugus and 
Pipistrellus subflavus. It was surprising to take 47 of the relatively 
uncommon hoary bats, Lasiurus cinereus, most from April to October, 
but one each in December and January. Perhaps these latter individuals 
were hibernating in Indiana (20), although this species presumably 
migrates south for the winter. There are also isolated reports from 
Indiana and other states that suggest that red bats also may hibernate 
at this latitude (5). 

Except for Eptesicus and the two Lasiurus cinereus, most bats were 
taken during the months April through October, except for a few 
Myotis and Pipistrellus found in hibernation in caves. It is evident 
(Table 1) that there is much winter activity in Eptesicus, a hibernating 
species. Many of those taken were active at the time of capture, or were 
obviously recently active (found in a place where they would have been 
noticed). It is not known where the majority of the big brown bats 
spend the winter. Certainly, the large summer population in Indiana 
cannot be accounted for by the relatively small numbers that hibernate 
in Indiana caves, and banding records do not yet indicate long-range 
fall migrations. A group of 17 big brown bats found March 26, 1969, 
in a barn in Vigo County, was thought to have still been in winter 
quarters since the bats were torpid, there was no food in their 
stomachs or intestines, and they were wedged so tightly into tiny 
crevices that their skins were torn and myobiid mites on their 
abdomens were crushed when the bats were removed. Seven of the bats 
were found singly, but groups of 2, 3, and 5 were present. Six of the 
singles were female; the group of two consisted of two males, and the 
other groups each contained one male. Examination of the crevices on 
January 21, 1972, turned up no bats, hence the bats found earlier likely 
entered the barn after leaving their winter quarters. 

The records of Lasionycteris are of interest. The previous late 
spring record for this migrant was May 28 (14), but we have two 
individuals taken June 1 and June 10 from Lake County.

Reproduction 

There is but a single breeding record of Myotis sodalis for 
Indiana (13), but our additional June and July records further substan- 
tiate the conclusion that the species breeds there. There is little informa- 
tion on Pipistrellus breeding in Indiana. Eight gravid females were shot 
over a pond in Vigo County and appear to have been the small colony 
of bats using a nearby barn. The colony disappeared at the time these 
were shot. Embryos ranged from 11 to 21 mm crown-rump length (avg. 
14.3 mm). Six females contained two embryos each; two had one. An 
additional female, shot in Vigo County on June 30, had recently given 
birth, as had a female taken July 10 in Jefferson County. 

Ovulation in Eptesicus occurs about the first week in April in 
Maryland, and sperms are present in the female genital tract at this 
time (1) ; birth occurs about June 1, giving a gestation of about 2 
months. Eastern United States populations have two young per litter 
and western populations one (4, 6, 7). In 1971, three collections of big 
brown bats were made from a breeding colony in Putnamville, 
Putnam County, Indiana. On April 14, 7 of 14 females contained no 
visible embryos; one female appeared to have one tiny embryo; 6 
females appeared to have two tiny embryos each (counts based on 
uterine swellings). Each of 30 females taken May 14 was pregnant. 
Three each had one embryo; 27 each had two embryos. Embryos av- 
eraged 10.7 mm crown-rump length and varied from 4 to 16 mm. Each 
of 15 females taken May 24 was gravid; two had one embryo each and 
13 had two. The average crown-rump length of embryos was 17.3, with 
a range of 13 to 21 mm. In addition, two females from a Vigo County 
barn taken April 3, 1963, contained two tiny embryos. Our latest records 
of embryos in this species are June 1 and 2 (Vigo County) and June 
4 (Allen County). The first young of the year appeared in our sample 
in June. The smallest one, taken June 11, weighed 7.8 g, measured 60 
mm in total length, and had a forearm length of 20 mm. 

Copulation in Eptesicus fuscus occurs primarily in autumn, but 
may occur also during the winter (7, 16). Copulation of big brown bats 
has been reported in Indiana caves on November 23, January 8, 
February 7, and March 12 (10). Phillips (16) found sperm in the repro- 
ductive tracts of four of five females taken October 18, in each of four 
females taken October 29, and in four of five females taken in 
February and March, in northeastern Kansas. We examined five big 
brown bats (2 males; 3 females) taken March 26 in Vigo County. The 
males had living sperm in the epididymus; two of the females had living 
sperm in their uteri. 

Testis size has been found to be greatest in August, but regression 
occurred by the time of autumn copulation (4, 16). Testes size was tabu- 
lated, by month, for Indiana Eptesicus (Table 2). In August and 
September the highest percentage of males in the sample had testes 
more than 5 mm long and testes size averaged greatest in those 
months. This indicates that the largest amount of breeding activity 
takes place in August and September, but judging from testis size males 
may be capable of breeding much of the year.

Few red bats were taken that could be classed as adult males. From 
April through June, before young males entered the population, only 
11 of 56 (19.6%) adult red bats were males. A similar sex distribution 
has been found in Kansas (3, 8). 

Of 13 gravid female red bats examined, 2 each had 2 
embryos, 7 had 3, 2 had 4, 1 had 5, and 1 had embryos destroyed by shot. 
An average of 3.2 embryos among 44 pregnant females has been re- 
ported (1). The earliest embryos found by us were in a female collected 
April 30; she contained 4 measuring 1.8 mm in diameter. The latest date 
was June 19 (3 embryos 10 mm crown-rump length). Crown-rump meas- 
urements were made on other embryos as follows: May 9 (10 mm) ; May 
17 (10 mm) ; May 21 (9 mm) ; May 26 (6 mm) ; May 26 (12 mm) ; May 
26 (10 mm) ; May 31 (12 mm) ; June 5 (15 mm) ; June 14 (22 mm). The 
three embryos found June 14 were probably near term; the eyes were 
visible as dark spots and the milk teeth had erupted. Standard 
measurements of these young were total length 44, 44, 41 mm; tail length 
15, 12, 12 mm; hind foot length 6, 6, 6 mm. The one male had testes 1 by 
1.5 mm. Young taken with adult females on June 6, 14 and 17 were of 



380 Indiana Academy of Science 

similar size and were possibly newborn. Hamilton (6) stated that young 
were born about mid-June, while in Kansas and southern Illinois 
(8, 9) parturition occurs in late May and early June. A female taken 
April 19 appeared to have given birth, judging from the expanded and 
flaccid condition of the uterus. This would seem to be an unusually early 
date. Another female taken May 3 had four placental scars. Twenty 
females that had given birth were collected between June 20 and July 
20. It appears that most females give birth about mid-June in Indiana. 

The largest young taken with a female (3 young, July 14) meas- 
ured 79, 79, and 81 mm in total length and weighed 6.4, 7.4 and 7.6 g. 
Young only slightly smaller were taken with four other females on June 
20, June 23 and two on July 1. One young, taken with a female on June 
15, weighed 4.4 g. and was 64 mm total length (Table 3). The stomach 
of this young contained 60 chironomid and 40% Coleoptera remains. Two 
other large young taken with females had traces of vegetation and milk 
in their stomachs.

1 Forearm data not available on smallest two litters. 
2 Smallest not weighed. 



The 29 juvenile red bats less than 80 mm in total length and taken 
without accompanying females are of interest. We do not know whether 
some of this sample had been weaned, but suspect that most (or all) 
had merely become separated from their mothers. All of the above 
young were collected in late June and July (July 31 the latest) and all 
that had any food in their stomachs contained milk; two of them (with 
forearms of 31 and 27 mm) contained parts of ants and other insects 
in their intestines. Three large young found on June 30 had milk in their 
stomachs and intestines; the largest of this trio measured 91 mm in 
total length, had a forearm of 38 mm, and weighed 7.5 g. Judging from 
the growth rate of other young examined, this litter must have been 
born in early May. Two lone immatures taken July 28 and August 11 
contained only insect remains, thus were evidently independent of their 
mothers. These bats had total lengths of 85 and 86 and forearms of 36 
and 39 mm, respectively. It would appear that juvenile red bats tend 
to become independent of their mothers when about 80 mm in total 
length and weighing from 4 to 6 gm. 

None of 25 adult female red bats shot in June and July during our 
study were carrying young. Despite various records (6, 7) of females 



Zoology 381 

carrying their young on foraging flights, we do not feel that this occurs 
regularly. Females with attached young may be frightened from their 
roosts, thus fly off carrying the young (if the young are not too large) 
or be forced to the ground by the weight of large, attached young. More 
data are required on this. 

Hamilton (6) collected female red bats with quantities of sperm 
in their uteri the first week in August and stated that the species mates 
in August, while other authors (1, 7) thought mating probably takes 
place in August and September. Males taken in Indiana have the largest 
testes in August and September (Table 2) and although testes size alone 
is not necessarily proof of reproductive ability, it does suggest that this 
is the season of mating. 

Female hoary bats with two young each were taken May 23 (John- 
son County) and June 19 (Vigo County). The May young had total 
lengths of 79 and 80, forearm lengths of 36 and 37, and one weighed 
7.1 g. Comparable data for the young taken June 19 were total lengths 
100, 102; forearm lengths 42, 44; and weights 13.2 and 13.1 g. A 
lactating female captured May 28 gave birth to two young that day. 
Whether this was normal parturition is unknown, but there are 
numerous instances in the literature of births shortly after capture, 
some of which may be cases of induced abortion brought on by condi- 
tions of captivity. Caution should be used in considering such cases 
as parturition dates. Young are probably born in Indiana in late May 
or early June. Two small adult females (total length 105, 107, forearm 
51, 52) taken in late May, but showing no evidence of reproductive 
activity, suggest, on very limited data, that females might not breed 
their first year. 

Three evening bats each with two embryos were examined, one 
taken May 20 in Monroe County, one May 26 from Tippecanoe County, 
and one June 27 from Marshall County.

Discussion 



It is apparent that winter bat activity occurs in Indiana during the 
period when we generally assume that bats (especially Eptesicus fuscus, 
various species of Myotis, and Pipistrellus subflavus) are hibernating. 
Whether such activity is usual requires more investigation; it would 
seem that much of it, in the case of Eptesicus particularly, is normal. 
Urine in the bladder may cause bats to wake periodically (19). While 
the need for water may be responsible for winter movements (16), 
Rysgaard (17) felt that some food was necessary in winter, for he found 
chitin in the mouths of some bats; he also found that Eptesicus 
fuscus drank water in winter. Other authors also feel that winter 
activity is for feeding (1, 18). In Indiana, winter movement appears 
not to be related to feeding, based on stomach analyses of winter-taken 
specimens (Whitaker, unpublished data). Big brown bats have been kept 
for six months at 4.5°C without food with no ill effects (2). 

Delayed fertilization is presumably advantageous to bats, allowing 
them to mate in the fall when they are in good condition with plenty 
of food, thus avoiding an excess use of energy during early spring when 
energy may be at a premium. This advantage would seem to be 
negated, at least in part, if bats mate in winter, as appears to be the 
case in Eptesicus fuscus (10) and in Myotis lucifugus (23). Additional 
winter activity would further drain this energy and would seem to be 
strongly selected against, if energy is at a premium. It may well be that 
bats are physiologically adapted so that they can easily survive the 
winter on stored fat with energy to spare. Possibly, winter activity 
facilitates mating, ensuring that a high percentage of females become 
pregnant. This would be an advantage since the reproductive potential 
of bats is low (one litter per year and one to two young per litter in 
most species). Delayed fertilization may have evolved along with winter 
mating, allowing young to be born at the optimum time. Delayed 
fertilization might also be a mechanism by which bats take advantage 
of chance matings over extended periods of time. 

It also appears that Lasiurus cinereus and Lasiurus borealis, both 
considered migrant species that leave the latitude of Indiana in 
winter, may actually remain in winter. Possibly the portion of the total 
population that behave in this fashion is small, but we need further data. 
The fact that Lasiurus borealis will appear and fly about during 
periodic warm periods in mid-winter in Indiana indicates that these 
animals probably were nearby.

Rodent Seed Supply and Burrows of 
Peromyscus in Cultivated Fields 

Wayne C. Houtcqoper 

Department of Life Sciences 

Indiana State University, Terre Haute, Indiana 47809 

Abstract 

Food supply, in the form of seeds, was investigated in corn and soybean fields in 
Vigo County, Indiana, to determine what effect availability of this food had upon the dis- 
tribution and abundance of prairie deermice, Peromyscus maniculatus bairdii, and house 
mice, Mus musculus. Food was abundant in all study areas and did not adversely affect 
the distribution or abundance of either species. 

Twelve burrows constructed by P. m. bairdii were examined and sketches of two of 
these are presented. The burrows averaged 16.0 feet long, 4.1 inches deep, and had 6.0 
branches with only one opening per burrow. The branch nearest the opening commonly 
had a deep V-shaped tunnel which may serve as shelter during periods when the ground 
is being worked. Chambers containing feces, nesting material, or food caches of seeds were 
frequently found. 

Introduction 

Food supply has often been thought of as an important factor 
limiting distribution and abundance of animals (1, 5), but there are con- 
flicting reports (2, 3, 4) which indicate that food is not an important 
factor limiting the distribution of Peromyscus. The present paper is 
an attempt to determine if food, in the form of seeds, is a critical factor 
influencing the distribution and/or abundance of two common rodents, 
Peromyscus maniculatus bairdii and Mus musculus, in cultivated 
habitats of Vigo County, Indiana. 

Peromyscus maniculatus bairdii constructs burrows, but there are ap- 
parently no previous reports describing the burrows. Burrows examined 
during this study are described. 

Study Areas 

Three separate areas totaling approximately 2,800 acres were chosen 
for study, with corn and soybeans being the most prevalent cultivated 
crops. Area (Sees. 21, 22, 27, 28, T13N, R9W), 1,100 acres, 3 miles north 
of Terre Haute, Indiana, was adjacent to the Wabash River and was 
part of the Wabash Floodplain. Area 2 (Sees. 25, 36, T13N, R9W, Sees. 
29, 30, 31, T13N, R8W), 800 acres on the Wabash River terrace, was 
approximately 2 miles northeast of North Terre Haute, and was com- 
posed of 4 separate fields. Area 3 (Sees. 3, 4, 5, 8, 10, T12N, R8W), 900 
acres on an upland site, was 1 mile northwest of Seelyville, Indiana, 
and contained 4 separate fields. 

Methods 

Maps of each area were constructed using aerial photographs and 
vegetation maps. A scale of 1:4800 was used. Each map was divided 
into sampling plots of 76 by 76 feet numbered in rows from west to east 

384 



Zoology 385 

and with the first row to the north. Ten plots per area per trapping 
period were randomly selected for study. Plots not in cultivated fields 
were omitted. In each plot, 25 traps were set in 5 lines of 5 traps, with 
15 feet between each trap and 7.5 feet between the outer traps and the 
edge of the plot. 

Mammals for this study were collected during four trapping 
periods: July 1970; August 1970; September-October 1970; and 
December-January 1970-71. All specimens were taken by means of 
standard snap-back mousetraps baited with peanut butter. Traps in each 
area were checked each trapping period for 4 consecutive days, resulting 
in 12,000 trap-nights for the entire study. 

A square foot of soil, sampled to a depth of one-half inch, was col- 
lected in each study plot for seed analysis. Seeds were isolated 
according to a technique described by Malone (6). The seeds from each 
sample were placed in marked Petri dishes, dried in an oven, identified 
by comparison to known samples, and counted. 

A Chi-square goodness-of-fit test was used to determine sig- 
nificance of differences in the numbers of mice taken per trapping 
period. A completely randomized design of analysis of variance was 
used to determine significance of: 1) differences in the numbers of mice 
per species per study area, 2) differences in the total number of seeds 
per sampling period, 3) differences in the total number of seeds per 
study area. A t-test was used in cases where a significant F value from 
Analysis of Variance was obtained. 

Twelve burrows were examined in Area 2 during February and 
March 1970. Attempts at locating burrows in Areas 1 and 3 were unsuc- 
cessful due to the absence of snow and the onset of cultivation. Traps 
placed near the burrow openings yielded only Peromyscus maniculatus 
bairdii; thus the burrows were presumed to be those of P. m. bairdii. 

Results and Discussion 

Rodent, Population and Seed Supply 

During this study 414 prairie deermice (Peromyscus maniculatus 
bairdii), 252 house mice (Mus musculus) , 22 woodland deermice 
(Peromyscus leucopus) , 3 jumping mice (Zapus hiidsonius) , 2 prairie 
voles (Microtus ochrogaster) , and 1 rat (Rattus norvegicus) were taken. 
The totals for P. m. bairdii and Mus musculus were divided into numbers 
of mice per study area and per trapping period. There were no sig- 
nificant differences between the average number of M. musculus per 
plot in the floodplain (2.0), river terrace (2.4), and upland area 
(2.0) (F = 0.29, 119 df), indicating similar populations in the 3 areas. 
Average numbers of P. m. bairdii per plot in the floodplain (6.0), river 
terrace (2.7), and upland area (1.3) were significantly different 
(F = 28.96, 119df). Study plots in the floodplain area had more P. m. 
bairdii than those in the river terrace area (T = 5.04, 78 df), while those 
in the river terrace area had more P. m. bairdii than those in the up- 
land area (T = 2.44, 78 df).

an increase in late autumn followed by a decrease in winter 
(F = 4.29, 119 df). These results agree with those of Whitaker (7), who 
found that P. m. bairdii remained at roughly similar population levels 
throughout the year while Mus moved out of areas when ground cover 
decreased. 

Information on the number of seeds taken was summarized accord- 
ing to sampling period and study area (Table 1). Species which had 
an average number of seeds per sample greater than 5.0 are listed. Other 
species less frequently found were Datura stramonium, Cerastium 
vulgatum, Aster sp., Polygonum sp., P. pensylvanicum, Ambrosia 
trifida, Brassica kaber, Hypericum perforatum, Rumex crispus, Glycine 
max, and Zea mays. 

There were no significant differences in the mean number of seeds 
per sample per sampling period (F = 0.09, 119 df). There were, however, 
significant differences in the mean numbers of seeds per sample per 
study area (F = 51.60, 119 df), with the extremes in Area 1 of 47.7 seeds 
versus Area 2 with 177.4 seeds. Significant differences were also found 
in the mean numbers of seeds per sample between Areas 2 and 3 
(T = 5.88, 78 df). 

If food in the form of seeds is a critical factor, mouse numbers 
should be influenced by seed availability. Since no significant differences 
were found in the mean numbers of seeds per sampling period 
(99.6, 107.2, 107.2, 99.4), while significant differences were found in 
the number of M. musculus per sampling period, seeds as a food source 
apparently did not limit M. musculus numbers. The floodplain area had 
the fewest seeds per sample (47.7), yet this area contained the most 
P. m. bairdii per plot (6.0). No significant differences were found in 
the number of M. musculus per plot per area (F = 0.29, 119 df). 

The number of seeds per sample apparently did not influence the 
abundance of either P. m. bairdii or M. muscidus. 

Burrow Studies 

Burrows were most easily found when snow cover was present. The 
burrows constructed by P. m. bairdii appeared to offer an adequate 
habitat for living, feeding, and nesting. Two burrows are diagrammed 
(Fig. 1). 

The 12 burrows averaged 16.0 feet in length (range, 5 to 35 feet), 
and 4.1 inches in depth (range, 1 to 12 inches). The average burrow had 
6.0 branches (range, 1 to 12), and was 6.3 inches at its deepest point. 
Burrows ranged from 0.75 to 1.50 inches in diameter. Only one opening 
was found for each burrow. All of the burrows had a drop of 2 to 3 
inches from the opening, then a relatively straight tunnel of 4 to 6

inches before the first turn. The deepest point in the burrow was 
frequently found in the branch nearest the opening. This branch com- 
monly had a steep decline of 30 to 40°, then an abrupt incline at the 
same angle which opened into a chamber. Three of the burrows had 
caches of uneaten seeds, mainly Setaria, at this chamber site, indicating 
food storage by this species. The deep, V-shaped tunnel may serve as 
shelter during periods when the ground is being worked. Most of the 
burrow would be destroyed but this area would remain. Many of the 
other tunnels had similar chambers, but without the steep slope or in- 
cline before them. In 6 of the burrows, feces were found in these 
chambers. Eight burrows terminated in a large chamber and three of 
these contained nesting material of finely chewed grass, straw, leaves, 
and paper. In all cases, the main tunnel was free of debris. These find- 
ings indicate a high degree of burrow utilization by P. m. bairdii.

Abstract 

Young (1 month old) and old adult (13 months old) rats were subjected to a 
simulated high altitude (23,000 feet for 5 weeks) environment. The anoxic resistance of 
isolated right ventricles, right ventricular weights and hematocrit values were then 
measured in both sea level control and altitude-acclimated animals from both age 
groups. This research demonstrates that the hematocrit cannot be increased in older 
individuals to such an extent as in young individuals and that the right ventricular 
hypertrophic response to hypoxis is markedly decreased in the older animal. Older 
animals were shown to have increased their myocardial anaerobic competency as a result 
of the aging process. Young animals can be forced to increase their anaerobic competency 
by chronic exposure to hypoxia, but the old myocardium cannot be forced to induce 
further anaerobic competency by such hypoxia exposure. 

Introduction 

It has been well established that several parameters of the 
cardiovascular system are modified as a result of chronic exposure to 
the hypoxia of high altitude (9, 11, 16, 17, 29). Increased hematocrit, 
or polycythemia, has been shown to be a meaningful high altitude 
adaptation by several researchers, both on the basis of increasing the 
oxygen-carrying capacity of the blood (8, 11, 29) and of increasing the 
capacity of the animal to perform work under hypoxic conditions 
(7, 21). This enhanced erythropoietic activity has been shown to be 
mediated by a hormonal factor which produces bone marrow 
hyperplasia accompanied by an augmented rate of iron turnover (18, 
19). 

Right ventricular hypertrophy has been shown to consistently ac- 
company high altitude exposure, whether one employs laboratory 
animals acclimated to simulated high altitude or natively acclimatized 
high altitude species (9, 10, 31, 32). This right ventricular 
hypertrophy is reflected in the EKG as a right-axis deviation (20), and 
it has been shown to result from the pulmonary hypertension which 
accompanies the hypoxia of high altitude acclimation (1, 9, 20, 27.) 

In addition to these anatomical changes which accompany altitude 
acclimation, several investigators have demonstrated an increased

anaerobic capacity of the brain (2), straited muscle (2, 13, 17) and 
cardiac muscle (14, 15, 16, 17, 22), as well as an increased percentage 
recovery of cardiac muscle after an anoxic stress (23). 

By examining these three parameters— hematocrit, heart weight 
and myocardial anoxic resistance — in sea level rats and in altitude- 
acclimated rats whose ages ranged from young to old adult it would 
be possible to show whether or not the aging process had altered the 
animal's ability to develop these cardiovascular adaptations in response 
to chronic hypoxia. 

Materials and Methods 

Animals 

Male albino rats (Sprague-Dawley) were purchased from Purina 
Laboratory Animals, Vincentown, N. J. These rats were fed a special 
thyroxine-free synthetic diet (Vitamin B complex test diet, with salt 
mixture USP XIV substituted for Salt Mixture #2, completely vitamin 
and mineral fortified and pelleted for rats) purchased from Nutritional 
Biochemicals and tap water ad libitum. The animals were maintained 
on this test diet for 2 weeks before experimentation was begun, and 
this diet was administered for the duration of the experiment. Animals 
employed in the study were either 1 month or 13 months old. These rep- 
resent respectively young and older mature rats. 

Lighting, Temperature and Altitude 

Animals were maintained in the laboratory at 25±1®C, 
and the fluorescent lighting provided 12 hours of light and 12 hours 
of darkness daily. The altitude-exposed animals were maintained in 
altitude chambers at a simulated 23,000 feet above sea level (14, 15). 
The high-altitude animals were acclimated for 2 days at 7,000 feet, 3 
days at 10,000 feet, 3 days at 17,500 feet, 3 days at 20,000 feet, and for 
the remaining 5 weeks at 23,000 feet. These altitude-exposed animals 
remained at 23,000 feet for 72-hour intervals; they were then returned 
to sea level for 1 hour to allow for cleaning, disinfecting and feeding 
and were then depressurized to 23,000 feet for another 72-hour interval. 
This depressurization was accomplished gradually over an hour period 
so as to avoid aeroembolism. The "sea level controls" were maintained 
in the same laboratory at a Philadelphia, Pennsylvania, altitude of 
approximately 150 feet above sea level. 

Hematocrit Determinations 

The animals were anesthetized with ether, guillotined, and 
heparinized micro-hematocrit tubes were filled with blood from the 
severed carotids and were spun down on a clinical centrifuge to deter- 
mine each animal's hematocrit value. 

Right Ventricular Function Test 

After blood was collected for hematocrit determinations, the rat 
was restrained on a dissecting board, an incision was made from the 



:::iu 



Indiana Academy of Science 



ventral mid-line of the neck to the xyphoid process, and the ribs and 
musculature on the left side of the sternum were severed and sep- 
arated with a wound retractor. The pulsating heart was removed and 
placed in a beaker of well-aerated (95% 2 - 5% C0 2 ) 
Krebs-Ringer's bicarbonate solution to remove the excess blood. The 
right ventricle was dissected away (Fig. 1) and was rapidly transferred 
into the Krebs-Ringer's bicarbonate-filled muscle chamber (Fig. 2) 
which was aerated by the 95% 2 - 5% C0 2 mixture. After an initial 
stabilization period of 30 minutes, the aerating mixture was changed to 
95% N 2 - 5% C0 2 as an anoxic test. This anoxic test was applied for 
a 20-min period, and then the 95%0 2 -5% C0 2 mixture was re- 
introduced for a 20-min recovery period. During the entire test the 
isolated right ventricle was kept at 29° C and was driven at a supra- 
maximal stimulus strength (10 volts, 7 msec) at a frequency of one 
stimulus per second. The apical end of the excised ventricle (Fig. 1) was 
pinned and attached to an isometric strain gauge (Stratham Instruments). 
The output signal from the strain gauge was recorded on an Electronics 
for Medicine recording system, and the resting tesion of the excised 
ventricle was set a 1 g.

Heart Weight 

At the conclusion of each experiment, the excised right ventricle 
was blotted and weighed on a Mettler H 20 T (Fisher Scientific) and 
was analyzed on the basis of 100 g of body weight. 



Results 

Hearts were analyzed on the basis of right ventricular weight per 
100 g of body weight. Right ventricular weights were increased in both 
young and old adult rats by altitude exposure (Fig. 3). However, while 
altitude acclimation induces a 171% increase in right ventricular 
weight in the young (2 months of age) group of rats, the same 
hypoxic exposure elicits only a 69% increase of the same parameter in 
the older (14 months of age) group. 

Hematocrit values were determined and compared among both age 
groups at sea level and after altitude exposure (Fig. 4). When compared 
to sea level controls of the same age, altitude acclimation elicits a 
92% increase in the hematocrit value of the young group, but the older 
group shows only a 67% increase following the same chronic hypoxic 
exposure. The maximal hematocrit values achieved by the two groups

To compare both early and late responses to anoxia, contractile 
strengths were measured after both 120 and 480 anoxic contractions 
and were expressed as a percentage of the control preanoxic strength 
(Table 1); after the 20-min anoxic period had elapsed, the gassing 
mixture was switched back to 95% 2 - 5% C0 2 , and the 
recovery was measured after 960 additional contractions in the 
aerobic recovery period. The recovery was then expressed as a per- 
centage of the control preanoxic strength (Table 1). It can be seen that 
whereas altitude acclimation afforded the young animals no increase 
in preanoxic contractility after 2 min (120 anoxic contractions) when 
compared to young sea level controls and a 225% increase in the same 
parameter after 8 min into the anoxic period (480 contractions), the 
old altitude-acclimated animals showed no increase in anoxic resistance 
when compared to old sea level controls after either 2 min or 8 min. On 
the other hand, when compared to young controls, the old controls 
showed a 15% added anoxic resistance after 2 min into anoxia and a 
226% added anoxic resistance after 8 min of anoxia. Thus, while old sea 
level-control rats show a greater anoxic resistance than do young sea 
level-control animals, the anaerobic competency of the young ventricle 
can be increased to the same level as that of the old ventricle by 
chronic altitude acclimation. The older ventricle, however, cannot be 
forced to increase its anaerobic competency by altitude exposure. 

Both age groups were compared after 16 minutes of recovery with 
the 95% 2 - 5% C0 2 mixture (Table 1). While the young and 
old acclimated animals and the young sea level control animals have 
recovered 43%, 39% and, respectively, of their preanoxic contractility 
values, the old sea level control animals have regained only 26% of their 
original control value. 

Discussion 

While our results indicate that older animals do not show as great 
a percentage change in their hematocrit as do young animals in response 
to the same hypoxic stress, both age groups were able to reach the same 
maximal hematocrit value in response to the hypoxic stress. This find- 
ing contrasts with a previous study on humans by Dill (5, 6), in which 
he reports that both the rate and equilibrium value of hema- 
topoiesis during altitude exposure may be depressed by the aging 
process. These studies, however, involved only a few subjects who were 
tested after only a 2-week sojourn at 3,000 m. Our animals, on the other 
hand, remained at 7,012 m for 5 weeks. 

The fact that the older right ventricle does not show the extent 
of hypertrophy as does the young right ventricle in response to the 
hypoxia of chronic altitude exposure may be due to several factors. It 
has been established that the right ventricular hypertrophy of the 
altitude-acclimated animal results from pulmonary hypertension which 
accompanies exposure to hypoxia (1, 9, 20, 27). This implies, however, 
that: 1) the lung vasculature must be reactive to the hypoxia to which 
it is exposed, and 2) the right ventricle is capable of responding to this 
extra work load by increasing its muscle mass. The first of the require- 



Zoology 397 

merits is diminished by the aging process, for active microvascular 
responses are both more limited and slower in older animals (3, 33). 
The second requirement is modified by the facts that in the aging 
muscle there is a decrease in the concentration of DNA and 
RNA, there is a decreased uptake of amino acids by the older muscle 
cell and there is a decrease in essential transaminases required for pro- 
tein synthetic reactions (3). This decreased ability of the aging 
myocardium to respond to greater work loads by hypertrophy has been 
noted in the dialated ventricles of old rats (28). In addition, Poupa 
postulates that while young animals increase their cardiac muscle mass 
in response to increased work loads primarily by increasing the 
number of myocardial cells (hyperplasia), older animals respond to the 
added work load by increasing the size of pre-existing myocardial cells 
(24, 26). Furthermore, according to many researchers, there is an actual 
disappearance of patent vasculature in the myocardium of the old 
animal with aging (24, 25, 26, 30). As Poupa points out, "In young 
animals, overloading of the heart leads to an accelerated growth of both 
structures (cardiac cells and capillaries), while in adult animals growth 
is confined to cardiac cells only" (24). 

Thus, in comparison with the younger myocardium during hypoxic 
exposure, the aging heart may be given less of an increased work load 
as a result of less reactive pulmonary vasculature, the actual protein 
synthetic reactions required to effect an increase in ventricular mass 
are depressed by aging, and the older myocardium cannot increase the 
oxygen-supplying structures to the muscle cells while increasing the 
oxygen-consuming structures as can the young myocardium. All of these 
aging changes may contribute to the fact that the older myocardium 
responds with far less increase in muscle mass than does the young 
myocardium to a given hypoxic stress. 

Finally, this research indicates that while the aging myocardium 
possesses a greater anaerobic competency than does the young 
myocardium, the anoxic resistance of the older myocardium cannot be 
increased by exposure to chronic hypoxia while that of the young 
myocardium is greatly increased. This finding supports a recent obser- 
vation of McGrath et al. (unpublished, personal communication) that 
the older myocardium cannot be forced to increase its anaerobic com- 
petency by chronic hypoxic exposure. What might be responsible for 
the increased anerobic competency in the older sea level-control animal, 
and why could it be increased no further by hypoxic acclimation? It 
has been demonstrated that the oxidative metabolism of the myocardium 
decreases greatly with age with little or no deterioration of the 
glycolytic and dehydrogenating activity (3). Since ATP levels are main- 
tained at the normal level in the myocardium of the aging animal and 
since the ATP-ase activity of the myosin does not change with age (3), 
the demand of ATP for myocardial contraction in senility must remain 
unchanged. Since myocardial aerobic metabolism has decreased with 
aging, some alternative anaerobic metabolic mechanism must be em- 
ployed to a greater degree if energy requirements are to be met — i.e., 



398 Indiana Academy of Science 

if some enzymatic oxidative activities are decreased by the aging proc- 
ess, others must be increased compensatorily if energy requirements 
remain constant and are satisfied (3). Such a mechanism has been 
elucidated in the aging erythrocyte, such that as its aerobic competency 
decreases with age, its anaerobic competency increases so that the con- 
centration of ATP remains constant (3). The search for such a 
mechanism in the aging myocardial cell continues, however, for the 
pentose phosphate pathway appears to remain relatively unchanged 
(3) and the total LDH activity reaches its peak and then begins to de- 
crease at 30 weeks of age as do the H 4 end M 6 isoenzymes (12). 

If the myocardial cell in the older animal is employing its 
anerobic processes to a greater degree than is the young myocardial cell 
in compensation for a decreased aerobic capacity, one should expect 
to see evidence of a heightened anaerobic capacity in the older cell. 
Indeed, our results indicate the presence of such an increased 
anaerobic competency as added anoxic resistence in the older 
myocardium. Also, since the diffusion distance for oxygen from the 
coronary capillaries to the myocardial cell is increased in the aging 
ventricle due to hypertrophy of the myocardial cells and to the disap- 
pearance of patent capillaries (24, 25, 26, 30), local cellular hypoxia 
may also have further induced the development of a greater anaerobic 
competence in the older heart (4). From the results of this experiment, 
it would appear that the young myocardium can be influenced by chronic 
hypoxia to increase its anaerobic competence to the maximal level at 
which the older sea level controls are already operating. Under these 
experimental conditions, the old adult cannot be stimulated to increase 
its anaerobic capacity above this maximal level.

Heat- Stressed Chicks of Different Ages 1

Abstract 

Chicks are capable of discriminating various taste stimuli and their aversions 
for cyclamate and preferences for glucose are similar to those reported for various 
rodents. The age differences found here deserve further investigation as does the effect 
of heat-stress during incubation on preference behavior. 

Introduction 

Preferences for various sugars are found throughout the animal 
kindgom, particularly among mammals. Until recently, reports of sugar 
preference in chickens had been sporadic and contradictory (4, 5). How- 
ever, Wagner and Gunther (9) have shown that new-born chicks have 
definite preferences for glucose and sucrose over water and gradually 
develop an aversion for lactose. Higher incubation temperatures (heat- 
stress) failed to result in marked sugar preference differences although 
heat-stress has been shown to produce marked differences in other be- 
haviors such as discrimination learning, reversal learning, frequency 
of pecking, and color preferences (1, 2, 3). 

Research on sweeteners other than sugars (sweet as judged by 
humans and accepted as rewards by rodents) as well as the well- 
publicized ban on cyclamates has spurred the study of preferences for 
various substances such as saccharin and cyclamate. Wagner (6, 7) and 
Wagner and Gunther (9) have found several rodent species which prefer 
saccharin and avoid cyclamate. Whether this cyclamate aversion is be- 
cause of its taste (or off -taste) or to the suspected toxicity of 
cyclamates has not been resolved. 

The purpose of the present study was to examine preferences for 
saccharin, cyclamate, glucose, and water in normal and heat-stressed 
chicks at various ages. The chemicals were purchased from a chemical 
supply house and are of reagent grade. 

Methods 

All control and experimental chicks were hatched from buff White 
Rock eggs in commercial Montgomery Ward incubators, modified for 
electronic control of temperature within ±0.5°C. Humidity was kept con-

stant. Both temperature and humidity were continuously monitored and 
recorded during incubation by electronic recorders. The eggs were 
turned 3 times each 24-hour period. The sugar, saccharin, and cyclamate 
solutions were made with tap water and the strength of the solution 
determined on a weight/volume basis. The concentration of the sugar 
was standardized at 8% and 16%, sodium cyclamate at 0.91%, 
the calcium cyclamate at 1.81%, and sodium saccharin at 0.23%. 
These concentrations have been noted in the literature and are well 
above threshold for all animals that have been tested. The reasons for 
the choices of values have been discussed elsewhere (9). 

Control chicks were hatched from eggs incubated at the optimal 
temperature of 37.5° C for 21 days. Experimental chicks were placed 
in a nonoptimally high temperature incubator at a temperature of 
41°C for the first 72 hours of incubation, after which they were placed 
in the normal temperature incubator until hatching. After hatching, the 
chicks were banded and placed in heated starting battery brooders, 
eight or nine chicks per group. The solutions were presented in a water- 
ing trough with three removable waterproof sections containing water 
and the various concentrations of sweeteners (see reference 10 for ad- 
ditional details of presenting solutions and measuring solution intake). 
Table 1 shows the experimental paradigm. 

Measurement of daily intake was made in Class A graduated 
cylinders to the nearest milliliter, and the volume recorded was the total 
intake for each group of chicks. The solutions were discarded after 
measurements, and fresh solutions were introduced from the 
refrigerated stock. 

Commercial starting mash was available to the chicks at all times. 
The chicks were completely isolated from other animals and humans, 
except for those periods necessary to rotate the sections and to measure 
and change the solutions. Humidity and temperature were kept constant 
in the battery room since this facility had no windows (zone air- 
conditioning). Light-dark conditions were made to match those of the 
normal day-night at this time of the year. The experiments were con- 
ducted during July and August. 

Results 

Since chicks were housed in groups (for practicality as well as the 
necessity of rearing infant chicks in a warm environment) , measurement 
of individual intake and preference was precluded. Because of this, the 
analyses of variance were more limited in scope since the interaction 
variances had to be used as error terms instead of within and between 
subject variability, and all interpretations would, therefore, tend to be 
conservative estimates of actual differences. 

The data for the analyses are per cent intake, and for graphical 
presentation are mean per cent intake with the standard error of the 
mean as a vertical line to indicate variability. Per cent intake was used 
since this method of computation equates for greater bodyweight in

Zoology 405 

Experiments 1 and 2, Group I (water; 8% glucose; 0.91% 
sodium cyclamate) vs. Group II (water; 16% glucose; 0.91% 
sodium cyclamate) showed no overall difference between the two condi- 
tions of having differing glucose concentrations available. Glu- 
cose was significantly preferred to both water and cyclamate 
(F = 42.089; df =2/2; p<.025) regardless of its relative concentration 
(see Table 1 for distinctions relating to Experiments 1 through 4 and 
Groups I through III). 

In Experiments 1 and 2, Group I (water; 8% glucose; 
0.91% sodium cyclamate) vs. Group III (water; 8% glucose; 
1.81% calcium cyclamate) there were no overall intake differences 
in preferences which could be traced to the two different salts or con- 
centrations of cyclamate. Eight per cent glucose was preferred 
to water or cyclamate regardless of cyclamate salt or concentration 
(F = 21.50; df = 2/2; p<.05). 

Experiment 3 (4-day-old chicks) 

Four-day-old chicks did not discriminate between water, 16% 
glucose and 0.91% sodium cyclamate (Group II), nor were their 
preferences different from those chicks which received water, 
8% glucose and 0.91% sodium cyclamate. However, when the choices were 
different cyclamate salts and concentrations (Group II: water, 
16% glucose; 0.91% sodium cyclamate vs. Group III: water; 
16% glucose; 1.81% calcium cyclamate) overall analysis indicated that 
cyclamate was not preferred (F = 1,350.959; df = 2/2; p<.001), 
heat-stressed chicks preferred glucose to cyclamate F = 66.81; df = 2/2; 
p<.025), and chicks having 1.81% calcium cyclamate as a choice pre- 
ferred glucose and avoided cyclamate to a greater extent than chicks 
having 0.91% sodium cyclamate as an alternative (F = 1,218.143; df 
= 2/2; p<.001) (Fig. 2.) 

Experiment 4 (17-day-old chicks) 

Seventeen-day-old chicks preferred glucose (either 16% or 8%) to 
water or saccharin (Groups I and III) (F = 24.44; df =2/2; p<.05). 
If the choices involved cyclamate or saccharin (Groups II and III re- 
spectively) chicks preferred glucose to either water or the artificial 
sweetener (F = 78.37; df = 2/2; p.<.025) and further, Group III chicks 
drank relatively more saccharin (and less 8% glucose) and Group II 
chicks drank relatively less cyclamate (glucose II vs. glucose III, 
t = 4.373; df = 14; p<.001; saccharin III vs. cyclamate II, 
t = 4.19; df = 14; p<.001) (Fig. 2). 

Age Differences 

Thirty-day-old chicks preferred glucose to either water or sodium 
cyclamate while four-day-old chicks were indiscriminate (water; 
16% glucose; 0.91% sodium cyclamate; F = 36.513; df = 2/2; p<.05). 
Any differences between 30-day-old and 4-day-old chicks when presented 
with choices of water, 8% glucose, and 0.91% sodium cyclamate were not 
due to experimental manipulation, but were the results of excessive 
variability.

experiment. 



Seventeen and 30-day-old chicks were both given choices of water, 
8% glucose, and 1.81% calcium cyclamate. For all chicks glucose intake 
was greatest and cyclamate least (F = 2,403.959; df = 2/2; p<.001). 
Heat-stressed chicks drank relatively more water, less glucose and equal 
small amounts of cyclamate — still preferring glucose, however, 
(F = 35.325; df =2/2; p<.05), and finally, the younger chicks (17 days 
old) showed a more pronounced glucose preference (F = 26.435; 
df = 2/2; p<.05) (Fig. 3). 

Discussion 

Wagner and Gunther (10) previously have shown that chicks can 
discriminate various taste stimuli, preferring some over water, while 
avoiding others. The present studies clearly reinforce this. 

Chicks consistently avoid cyclamates, the sole exception being 
4-day-old chicks which were indiscriminate to a 16% glucose or 0.91%

sodium cyclamate. Are chicks avoiding cyclamates because of the 
suspected toxicity of cyclamate, or because of some taste-quality 
inhert in cyclamate solutions? Dr. Jacqueline Verrett (unpublished re- 
search progress reports, U.S. Food and Drug Adm.) found that 
cyclamate injected into incubating eggs produced embryonic deformities, 
but it is difficult to generalize from such studies to food preferences 
or aversions (6). Chicks reject toxic lactose, but the aversion develops 
gradually (10). In the present study, the nonintake of cyclamate was 
immediate, suggesting that taste rather than toxicity accounts for the 
aversion. This same phenomenon has been observed in rodents (7, 8, 9). 

A comparison of rodent and chick preferences and aversions for 
sweeteners does not imply that these two species inhabit similar 
sensory worlds in general. However, the universality of the chemical 
sense and its function in food selection might lead one to expect some 



408 Indiana Academy of Science 

similarities in taste preferences for simple sweeteners. Since, in 
nature, sweets are a source of calories basic to the energy requirements 
of all living creatures, especially warm-blooded animals, it is quite 
logical to make comparative analyses of sweet preferences and aversions 
across diverse species with some expectation of finding similarities. 

While chicks never preferred the saccharin to glucose, comparative 
data from rats and mice would suggest that this should not be expected 
since rats and mice prefer 8% glucose to 0.23% sodium saccharin 
(8, 9). 

Perhaps a better test of relative palatability of the two artificial 
sweeteners is the observation that saccharin was drunk to a much 
greater extent than 1.81% cyclamate under similar conditions by 
17-day-old chicks. 

The effects of heat-stress during incubation are overshadowed by 
preference differences because of age and type of choice available. In 
fact, heat related differences might be considered equivocal since heat- 
stressed 4-day-old chicks drank relatively less water and more glucose 
than their normal counterparts, whereas heat-stressed 17-day-old and 
30-day-old chicks drank relatively more water and less glucose than 
their normal counterparts. Previously cited research also found stress 
differences to be less pronounced than preference differences because 
of type of sugar choice available.

INSTRUCTIONS FOR CONTRIBUTORS 

Eligibility 

Indiana Academy of Science members in good standing are eligible to submit 
papers for publication in the Proceedings. When a paper is signed by more than one 
author, at least one must be a member of the Academy. Preferably, eligibility should be 
established before submitting the paper, as such papers are given priority. In any case, 
all authors must be certified by the treasurer for payment of dues and old reprint bills 
at the time of the deadline (see below). Invited papers may be considered for publication 
regardless of the membership status of the author. 

All papers submitted for publication in full will be reviewed by qualified reviewers, 
selected by the Publications Committee. Papers read by the title only at the Fall Meeting 
may also be considered for publication. Among papers of primarily regional interest, 
e.g., in certain aspects of botany, zoology, geology, geography, and anthropology, those 
dealing with Indiana material will be accorded preference. The selection of papers for 
the Proceedings is the responsibility of the Publications Committee. 

Abstracts 

Three copies of an abstract should be submitted to the Divisional Chairman at the 
time the title of a paper is submitted for the Fall program. All abstracts will be pub- 
lished in the Proceedings, either separately or with papers that are published in full. 
Two copies of the abstract should be marked "for the editor." The third copy of the 
abstract should be marked "for the divisional chairman." and may include information 
about time, projection facilities needed, etc. The abstract should be prepared according 
to the form currently used in the Proceedings (see the latest copy of the Proceedings) 
The abstract should be complete, clear in itself and not over 5% of the length of the 
paper. Normally abstracts should not exceed 200 words in length. Abstracts are not 
reprinted (except for those which are included at the head of a paper published in full). 

Deadline at the Editorial Office 

When sent via the Divisional Chairman as prescribed, or directly, all material to be 
considered for publication in the Proceedings must reach the editor within 20 days 
following the Fall Meeting. 



Preparation of Manuscripts 

A. Refer to the latest copy of the Proceedings for the accepted style of abstracts and 
papers, and follow this, especially in literature citations, headings, footnotes, table 
and figure construction. 

B. Type on 11 x 8%-inch bond paper with a new ribbon, leaving some margin. 
Double space everything, including title, author's name, department and institution, 
footnotes, quotations, legends and literature list. Manuscripts must be submitted in 
duplicate. The original will become the printer's copy; if it must be retyped, it will 
be sent back to the author for this. 

C. Footnotes are to be kept to a minimum. Necessary footnotes are numbered consecu- 
tively throughout, and referred to in the text as superscripts, without parentheses. 

D. Literature citations are listed alphabetically at the end of the paper, headed 
Literature Cited. List complete literature citations, i.e., author, date, title, 
journal, (or publisher, and city), volume and total pages. The highly abbreviated form 
used in some journals has not been adopted for the Proceedings. Follow these 
models: 

7. Doe, J. B., and R. C. Roe. 1949. New light from old radioactive carbon. J. Amer. 
Biol. Sue. 34:273-305. 

8. Milazzo, G. 1963. Electrochemistry. Elsevier Publ. Co., New York, N. Y. 708 p. 

References cited should be numbered consecutively (in the alphabetized list) and 
should be referred to in the text by number in parentheses on the line of type and 
before the period if at the end of a sentence.

Instructions for Contributors 411 

E. Do not underline anything except scientific names, words to be italicized, and titles 
of books when they appear in the text only, not in literature list. 

F. All literature listed, tables and illustrations should be referred to in the text. 

G. Tables, which are costly to print, should be reduced to a minimum. Avoid small 
tables, scattered through the text. Each table (including heading) should be typed 
on a separate letter-sized sheet and placed at the end of the paper. Outsize tables 
cannot be accepted. 

H. Photographs should be printed on glossy paper and have good contrast. It is best to 
mount them trimmed to fit tightly together at the edges in groups, on stiff card- 
board with rubber cement. Proportion the group for a full page of the Proceedings, 
or use the full width of the paper (4%") and any part of the page's 
height. Do not mix line drawings and photographs in the same group. All figure cap- 
tions should be on a single letter-size sheet, numbered to correspond and placed at 
end of paper. 

I. The originals for line drawings need be no more than twice the size desired for the 
printed figure. They should be proportioned and arranged to fit the page size of the 
Proceedings. All line drawings must be drawn in India ink, lettered with a lettering 
set, and of suitable size to allow for necessary reduction. Do not submit printed 
maps when the necessary reduction will efface the narrower lines or render some 
of the lettering hardly legible; such maps should be redrawn and lettered in adequate 
size letters, omitting unnecessary details. All illustrations requiring a size scale 
must portray the scale in a manner that permits size reduction. 

J. Major professors are urged to review all papers by their graduate students, for both 
form and content, before they are sent in for publication. Of those based on uni- 
versity theses, manuscripts carrying the approval by the professor will be given 
preference over those without such approval. New authors, especially, are reminded 
that a scientific paper should summarize the work, not recapitulate it. It must be 
much more concise than a university thesis, avoiding all extraneous material 
especially long tables and lists of little interest except to the author. All manuscripts 
should be as concisely written as possible. 

K. Reprints of papers are paid for by authors, at cost. Directions for ordering re- 
prints accompany the galley proof and the orders are placed at the time the author 
returns the corrected galley proof to the editor. The order forms supplied with the 
galley proof must be completed and returned to the editor along with any special 
institutional forms regarding payment for the reprints. Abstracts are not reprinted. 

L. The editor needs, at the time he mails out galley, current addresses for all authors 
and co-authors of all abstracts and papers. Many former graduate students lose the 
opportunity to order reprints when there are faulty forwarding addresses. It is 
suggested that the student's permanent home address be written on the reverse side 
of the abstract copy marked "for the editor."
