2 BULLETIN 324, U. S. DEPARTMENT OF AGRICULTURE. 
The evolution of this particular cotton industry is toward the grow- 
ing of one superior variety of long-staple cotton exclusively. Of the 
problems connected with the industry, possibly the most important 
at this time is that of establishing a consistent production of large 
average yields of high-quality fiber.t The full possibilities of the 
industry will most quickly become realized by directing community 
effort toward the stabilization of long-staple cotton. 
It is proposed in this paper to explain what is meant by stabiliza- 
tion, its bearing on the different interests involved in the production 
and marketing of long-staple cotton, and the manner in which the 
stabilization can be brought about. A discussion of the development 
of the industry is included, for the purpose of making clear the 
steps that have been taken toward the adoption of a long-staple 
variety.” 
HISTORY OF THE INDUSTRY. 
IMPERIAL VALLEY IN CALIFORNIA AND MEXICO. 
The Imperial Valley is a portion of the delta of the Colorado River 
which extends some 40 miles on either side of the international 
boundary between the State of California and Lower California, 
Mexico. Cotton growing, like other agricultural enterprises, is prac- 
tically continuous across the boundary. The irrigation System car- 
rying water into California comes through Lower California, and the 
irrigation water for both sections is taken from the same main canal. 
Quarantine measures to guard against infestation by destructive in- 
sects are administered by California State and United States Federal 
authorities, and are designed to give these officers reasonable control 
over shipments of seed to and from Mexico, as well as into California 
from the Eastern States. The interests of cotton growers in Cali-

2Investigations incident to establishing the long-staple cotton industry in the South- 
west are carried on under the general direction of the Southwestern Cotton Culture Com- 
mittee. The following is the personnel of the committee: 
C. S. Scofield, Agriculturist in Charge of Western Irrigation Agriculture, is chairman of 
the committee and, in addition, has charge of those phases of the work which involve 
cooperation with the United States Reclamation Service. The author of this bulletin has 
been Mr. Scofield’s field assistant in this work. 5 
W. T. Swingle, Physiologist in Charge of Crop Physiology and Breeding Investigations, 
has charge of those phases of the work which involve cooperation with the Office of 
Indian Affairs. The Cooperative Testing and Demonstration Garden at Sacaton, Ariz., is 
under Mr. Swingle’s direction. 
O. F. Cook, Bionomist in Charge of Crop-Acclimatization and Cotton-Breeding Investi- 
gations, conducts investigations of the factors involved in the acclimatization of different 
types of cotton in the Southwest and of the relation of these factors to cultural methods. 
He has also been active in developing the idea of community cotton growing as a means 
of maintaining uniform varieties. 
T. H. Kearney, Physiologist in Charge of Alkali and Drought Resistant Plant Investiga- 
tions, has charge of the breeding work with Egyptian cotton and of investigations of the 
effects of alkali and other soil conditions upon the production of this crop. 
Cc. J. Brand, Chief of the Office of Markets and Rural Organization, has charge of the 
investigations in classing, marketing, and transportation.
