14 BULLETIN 742, U. S. DEPARTMENT OF AGRICULTURE. 
Tt has been the policy of the committee since its organization to 
avoid a sharp segregation of the different fields of investigation. 
As a result, each member has felt free to offer suggestions and even 
to assume responsibility beyond the limits of his own field, while 
the more important issues which have successively arisen in connec- 
tion with the establishment of the industry have been decided by 
the whole committee. It is believed that this committee coopera- 
tion has been of the greatest importance in the successful establish- 
ment of the industry, since it has resulted in focusing upon the 
problems the different,points of view and different mental. equipment 
and training of several independent investigators. 
Cooperative action having thus been provided, the economic prob- 
lems were attacked, as follows: 
(1) The principle of community effort in cotton production was applied in the 
organization of associations of growers. 
(2) A supply of labor sufficient for the earlier requirements of the industry 
was developed through the employment of Pima and Papago Indians as cotton 
pickers, the first experiments having been made at the Cooperative Testing 
Garden at Sacaton under Mr. Swingle’s direction. Frank M. Thackery, for- 
merly superintendent of the Pima Indian Reservation and now chief supervisor 
of farming in the Office of Indian Affairs, rendered effective cooperation in this 
work. 
(83) Methods for classing the new product were worked out, and grade and 
staple types were established, first for the Yuma variety and later for the Pima 
variety, by J. G. Martin and George Butterworth, of the Bureau of Markets. 
(4) The American and European markets fur this type of cotton were in- 
vestigated by representatives of the associated growers and of the Depart- 
ment of Agriculture, contacts with buyers and spinners were established, and 
outlets for the product on the basis of full market value were thus obtained. 
(5) In cooperation with the associated growers, Measures were taken to in- 
sure a supply of pure seed for planting each year. | 
COOPERATIVE ORGANIZATION OF THE GROWERS. 
When the Yuma variety of Egyptian cotton developed by the 
Department of Agriculture had been shown to possess the qualities 
needed for successful commercial production, it was pointed out 
that the industry could be successfully established only by community 
effort and that the department stood ready to furnish a supply of 
seed for planting, provided the growers were able to form a. coop- 
erative association. Farmers in the Salt River Valley had watched 
with interest the experiments with Egyptian cotton at Sacaton and 
had conferred with the superintendent of the cooperative garden 
tion Service and has also conducted certain inyestigations of market conditions in the 
United States and in Europe. 
W. T. Swingle, Physiologist in Charge of Crop Physiology and Breeding Investigations, 
has charge of those phases of the work which invoive cooperation with the Office of Indian 
Affairs, including the arrangements for securing Indian labor. 
Fred‘ Taylor, Cotton Technologist of the Bureau of Markets, has:the immediate super- 
vision of the classing, marketing, and technological problems.
