MONTHLY LIST OF PUBLICATIONS
SEPTEMBER 1935 f
Any five of the nontechnical publications listed herein, except those otherwise noted, may be
obtained free upon application to the United Slates Department of Agriculture, Washington,
D. C., as long as the Department's supply lasts. After this supply is exhausted, publications
may be obtained from the Superintendent of Documents, Government Printing Office, Wash-
ington, D. C., by purchase at the prices stated herein. His office is not a part of the
Department of Agriculture.
Free distribution of technical material and periodicals is restricted.
These bulletins discuss in nontechnicnl language a wide variety of subjects pertaining
to the farm and farm home.
The native persimmon. W F. Fletcher, Bureau of Plant Industry. 22 p., illus.
(F. B. 685F., rev.) Price, 50.
Greenhouse tomatoes. James H. Beatlie, Bureau of Plant Industry. 28 p., illus.
(F. B. 1431F., rev.) Price, 5f.
The European corn borer: Its present status and methods of control. D. J. Caffrey,
Bureau of Entomology and Plant Quarantine. 39 p., illus. (F: B. 1.4SF.,
rev.) Price, 50.
Spray-residue removal from apples and other fruits. M. H. Haller, Edwin Smith,
and A. L. Ryall, Bureau of Plant Industry. 26 p., illus. (F. B. 1752F.)
Up to the present time no spray has been found that is nontoxic to humans,
effective in controlling the codling moth, and economically feasible. Until such a
spray is found the fruit grower must conti-nue to rely on lead arsenate or other
toxic materials and remove the excessive residue.
The Technical Bulletins contain the results of scientific and research work applying to
a special crop, industry, or locality. The editions are limited as they are intended pri-
marily for scientific workers and subject-matter specialists.
The desert milkweed (Asclepias subulata) as a possible source of rubber. R. E.
Beckett and R. S. Stitt, Bureau of Plant Industry. 20 p., illus. (T. B.
472T.) Price, 50.
Strains of this milkweed were established in cultivation with seed collected from
wild plants growing in the vicinity. This afforded material for cultural and other
experiments and for comparisons with wild plants. The nature of these experi-
ments and the results obtained are contained in this bulletin, with notes on the
description and distribution of the species.
The use of carbon disulphide against the Japanese beetle. W. E. Fleming and
F. E. Baker, Bureau of Entomology and Plant Quarantine. 92 p., illus.
(T. B. 478T.) Price, 10.
In view of the general interest in carbon disulphide for the control of soil-
infesting insects, this publication attempts to bring together a summary of the
published and unpublished experimental data and the pertinent facts relating to
the use of this chemical against the Japanese beetle.
Organization and management of apiaries producing extracted honey in the white
clover region. R. S. Washburn, Bureau of Agricultural Economics, and
G. E. Marvin, Bureau of Entomology and Plant Quarantine; in cooperation
with the State College of Agriculture and the Agricultural Experiment Sta-
tion at Cornell University, the College of Agriculture and the Agricultural
Experiment Stations of the Universities of Wisconsin and Minnesota, the
State Colleges of Agriculture of Michigan and Iowa, and Ohio State
University. 44 p. illus. (T. B. 481T.) Price, 50.
This bulletin shows the organization of the extracted honey business in a number
of apiaries in the region and the cost of producing extracted honey, and traces the
variation from aplary to apiary of some of the factors relative to economy and
efficiency in the production of extracted honey.
Effect of alfalfa and farm manure on yields of irrigated crops in the Great Plains.
Stephen H. Hastings, Bureau of Plant Industry. 40 p. (T. B. 483T.)
This publication describes 21 years of experiments with farm manure and alfalfa
on subsequent crop yields at the Belle Fourche. Huntley, and Scotts Bluff Field
Stations. These stations are located in the northern part of the Great Plains.
The crops involved are sugar beets, potatoes, and oats.
This series carries the less technical and more informal material of the same general
nature as that in the Technical Bulletin series.
Slash disposal in ponderosa pine forests of the Southwest. G. A. Pearson and
Arthur C. McIntyre, Forest Service. 29 p., illus. (Cir. 357C.) Price, 50.
The purpose of this circular is to assemble information acquired in part by the
process of trial and error through years of practice, in part by experimentation
and measurement, and in part by analysis of statistics.
A device for separating different lengths of fibers from seed cotton. Homer C.
McNamara and Robert T. Stutts, Bureau of Plant Industry. 16 p., illus.
(Cir. 3600.) Price, 50.
The writers have developed a sorter for seed cotton to a point where the general
mechanical details have been worked out. It has certain advantages which may
prove useful to others and which may be further refined by them through use and
Removing smut balls from seed wheat. W. M. Hurst and W. R. Humphries,
Bureau of Agricultural Engineering; R. W. Leukel, Bureau of Plant Indus-
try, and E. G. Boerner, Bureau of Agricultural Economics. 16 p., illus.
(Cir. 361C.) Price, 50.
Little effort has been made to determine the effectiveness of seed-cleaning equip-
ment and methods for removing dockage materials from grain in order to increase
its market value. This circular sets forth the possibilities of a number of grain-
cleaning devices in this direction.
Safflower, a possible new oilseed crop for the northern Great Plains and the far
Western States. Frank Rabak, Bureau of Plant Industry. 15 p., illus.
(Cir. 3660.) Price, 5N.
Safflower is suggested as a new dry land and irrigation crop for the production
of a drying oil to supplement the supply in the United States of other domestic
drying oils, the production of which does not equal the demand. It also seems well
adapted to winter dry-land farming in certain sections.
This series includes those publications of a miscellaneous nature which do not fall
within any of the other series issued by the Department. particularly those of a size other
than octavo. Such publications were formerly issued as Miscellaneous Circulars.
Rainfall intensity-frequency data. David L. Yarnell, Bureau of Agricultural
Engineering. 68 p., illus. (M. P. 204MP.) Price, 100.
This investigation was made to determine the frequency at which excessive rates
of precipitation occur in different sections of the United States. and the intensity
and duration of those rates. It is believed that this study has developed data
sufficient for predicting with reasonable accuracy the period of recurrence of
intense precipitations in any part of the United States.
Manual on preservative treatment of wood by pressure. J. D. MacLean. Forest
Service. 124 p., illus. (M. P. 224MP.) Price, 150.
Discusses the application of the results of certain experiments and observations
to the improvement of the pressure treatment of wood and presents general
information relating to the subject. Of value to engineers, treating-plant operators,
inspectors, and others interested in the preparation of specifications and in the
application of pressure-treating processes.
