DUG an J PACKED l^IGHT
THE second consideration is carefully dug trees. Evergreens that are dug right and that reach
the customer with a ball of soil that is compact and intact the way we send them, are pretty
sure to thrive.
The larger-sized trees are packed with a conical shaped canvas lashed and cross lashed about
the ball of soU that is held firmly to a wooden platform.
This is our own invention. Whether they remain in transit one day. ten days or longer makes
little difference. Smaller trees with fibrous roots have the usual burlap sewed on.
ADAPTED TO CLIMATE
I
EVERGREENS must stand not only the cold of winter but the
heat of summer. We offer only species that will stand severe
variation in temperature and wc have gone to the ends of the earth
to get them. They come from Kew England, Rocky Mountains in
Colorado, mountains of Northern Japan, Korea, Manchuria, Southern
Siberia, the Caucasus Mountains and the Balkan Peninsula.

A CHECK-LIST OF PLANTS MENTIONED IN
THE ARNOLD ARBORETUM BULLETINS
IN OCTOBER, 1914, we published a list of plants mentioned in
the Bulletins of Popular Information issued by the Arnold Arbore-
tum up to that time.
The present list includes almost all plants mentioned in the Bulletins
from their beginning, on May 2, 191 1, to the last number issued July
26, 1919. The list of October, 1914, is, of course, entirely revised,
corrected to date, and incorporated in this list.
Mr. E. H. Wilson, Assistant Director of the Arnold Arboretum,
has read this list in proof. For this kindness we wish to express our
thanks and our appreciation of the moral support implied.
We who have worked on this list (and the work has not been easy)
are again impressed by the value ot the work being done by the Arbore-
tum; in the introduction and testing of new varieties from different
parts of the world; in rescuing from oblivion many native plants of
limited distribution; in testing and pointing out the most valuable
varieties of common plants for garden use; and in fostering our inherited
love for plants as part of the natural landscape. It is a work which
must constantly increase in value as the trees and shrubs planted there
grow older and show their value or lack of value more clearly.

BOOK REVIEWS
REPORT OF THE UNITED STATES HOUSING CORPORATION. rU. S.
Bureau of Industrial Housing and Transportation.) Vol. II, Wash.ngton,
Government Printing Office, KjKj. 524 + xix pages, lllus., plans, iifa x 9
inches. Price $1.50.
The Housing Bureau was created to help win the war by providing for workers
in war industries such housing and living conditions as were required for the health,
self-respect, and efficiency of the workers, in order that the production and shipment
of munitions and supplies might not continue to be imperiled by the intolerable living
conditions caused by the war in manufacturing centers. This volume is a part of
the accounting which the Housing Bureau is called upon to make to the Secretary
of Labor and thus to the people of the United States. As a record of actual physical
achievement, when measured against the whole of the task which was to be performed,
it is like the record of most of the other government bureaus, which came to their
maximum activity and efficiency only shortly before the time when the armistice
made their efficiency of no further military value. Although the power of the Housing
Bureau for further creative effort has terminated, the need for proper industrial hous-
ing and town planning has not ceased with the war, as has the need for munitions.
There is now a great and growing housing shortage in this country, and the content-
ment and consequent efficiency of industrial workers is no less important to the
country in peace than in war. The Housing Bureau in endeavoring to do its job as
logically and effectively as possible was obliged to evolve certain methods of determin-
ing what the circumstances were in each housing problem dealt with, and certain
conceptions of what should be aimed at in handling these problems; and the records of
this organized thinking ought to be immediately valuable to such of us as are now deal-
ing with similar problems. Furthermore, the detailed records of the house plans and
housing schemes worked out by the Housing Bureau, even though less than half of
them ever came to construction, form much the largest available collection of data as
to comparative advantages and relative costs of work of this kind. The more important
items have been carefully stated and tabulated in the report, without, however, any
considerable attempt to draw from this mass of data the conclusions which it may
warrant, this being obviously too slow a process to be possible in the time.
Careful study and comparison of this material, however, should throw a great deal
of light on various practical points in industrial housing, and will be equally valuable
to the people of this country whether it shall incidentally also show that the Housing
Bureau was correct or incorrect in the various decisions which it was forced to make,
under stress, with such skill and information as it then had at hand.
To quote the editor's note:
"The accompanying volume endeavors to set forth in as small space as practicable
those activities and accomplishments of the Housing Corporation which were most
S4
BOOK REVIEWS 55
directly concerned with the design of its various housing projects. The general pro-
cedure of the corporation is discussed merely in those aspects which more directly
affected project design, and therefore, while the activities of the Architectural, Town
Planning and Engineering Divisions are fully covered herein, mention is made of
certain aspects only of the work of the Real Estate Division, the Transportation Divi-
sion, the Homes Registration Division, and the Construction Division, and only
occasional reference is made to the other divisions of the corporation, all of which are
to be considered in detail in Volume I of the corporation's report.
"The main body of the present volume consists essentially of three parts: (i) A
short general statement of how the Housing Corporation proceeded to ascertain what
the situation was in the community to be aided, and how it determined what its appro-
priate action for relief should be in each case; (2) a necessarily incomplete statement
of some of the general principles governing this kind of design which the design divi-
sions considered in their procedure or which they learned from their experience; and
(3) a short and compact record, in plans, perspectives, tables, and text, of what the
problem was which the corporation actually found in each of its important projects,
and what attempt was made to solve it, as a matter of complete and reasoned
design.
"This volume shows by plans and other drawings as much as was possible in the
allotted space about the more important projects; it states in tabular form, for com-
pactness and ease of comparison, all the information as to the projects which it was
practicable to represent by figures; and it sets down, in the text describing each pro-
ject, only those facts which were of particular interest or which had a special and impor-
tant influence upon the design.
"The appendix contains reprints of most of the directions which were issued by
the corporation as guides in design and construction, and the form of contract entered
into by the general contractor.
"A biblicgraphy is included covering the most important articles rn industrial
housing published during the war to April, 1919, compiled by the crnsuhing librarian
primarily from the references collected for current use in the work of tl e corpcr.T i n."
Chapters VI and VII, dealing with the general appearance cf the housin: pr jett
and scm.e ccnsideraticns as to costs and types of development, make no attempt at
any completeness of technical discussion; they merely set forth som.e of the more
fundamental considerations for the non-technical reader v. ho might want to know wl at
the problem was with which the Housing Corporation was concerned.
The project descriptions in Chapter VIII are similarly non-technical. The draw ings
consist mostly of simple layout plans showing the street system, the house-locations,
the lot-subdivisions, and in some cases the tree-planting. This simplicity enables the
plans to be reproduced each upon one page. The architectural drawings consist of first-
and seccnd-flcor plans, together with elevations or perspective drawings of the more
important types of buildings in each project illustrated. These plans and drawings are
more than ordinarily intelligible to the lay reader. It is a pity that more photographs
could not have been used, but the work under construction was obviously for the most
56 LANDSCAPE ARCHITECTURE
part in an incompleted state, so that photographs would not have been as explanatory
as the drawings are.
Although certain members of Congress, according to reports in the daily press,
seem to find the volume a useless piece of extravagance — an "account of a great effort
for future generations to know what somebody had done to aggrandize themselves,"
as Representative Treadway put it, — this record of experience will be of practical
productive value in the hands of municipalities, housing companies, employers of
labor, real estate men, technical designers of various sorts, and builders, who as tax-
paying American citizens are entitled to the information.
NOTE
IN the previous number of Landscape Architecture attention should
have been called to the fact that the minute upon the life of Charles
Mulford Robinson was written by Professor James Sturgis Pray, as
Chairman of a Committee, with Mr. Pitkin and Professor Frederic
Noble Evans, who were appointed for this purpose by the American
Society of Landscape Architects.
