makes it possible to formulate the conditions which appear to be 

 indispensable to the successful production of this crop in the United 

 States. These are, briefly, (1) a growing season of about nine 

 months, or several weeks longer than is required to mature a full 

 crop of Upland cotton; (2) a reliable supply of water for irriga- 

 tion; (3) labor sufficient to pick the acreage planted; (4) absence 

 of other types of cotton in the locality, as otherwise pure seed and 

 a uniform fiber can not be maintained; (5) an acreage sufficient to 

 warrant the purchase of roller gins' and other equipment and the 

 employment of a' competent classer in order to market the cotton in 

 even-running lots of commercial size; and (6) the cooperative organi- 

 zation of the growers for the purpose of maintaining the seed supply, 

 operating the gins, and marketing the crop. 



Communities in which all of the above conditions can not be met 

 are advised not to undertake the growing of Egyptian cotton. In 

 any event, a new community which contemplates the growing of this 

 crop should experiment at first on a small scale and under expert 

 advice, in order to make sure before investing capital in the enter- 

 prise that the climatic and soil conditions are favorable to producing 

 large yields and a good quality of fiber. 



CONCLUSION. 



The history of the establishment of Egyptian-cotton production 

 in the Salt River Valley is believed to have more than a special or 

 local interest, since it offers a good illustration of the numerous 

 biological, agronomic, social, and economic difficulties encountered 

 in developing a new agricultural industry and furnishes sugges- 

 tions as to how these complex and diversified problems may be suc- 

 cessfully solved. That cooperation is the keynote of success has be- 

 come very clear in the progress of the present enterprise. In this 

 instance cooperation has been maintained along the following lines: 



(1) Cooperation among the investigators has brought to the solu- 

 tion of the special problems different equipments of technical train- 

 ing and knowledge and different points of view, while their collective 

 judgment has been focused upon matters of general policy. The cor- 

 dial and effective cooperation of the administrative officers of the 

 Department of Agriculture has also been an important factor in 

 this connection. 



(2) Cooperation among the growers has made it possible to pro- 

 duce and market the crop economically and to maintain the uniform- 

 ity and high quality of the variety grown. 



(3) Cooperation between the growers and the investigators has 

 made it possible to put into effect without delay the most improved 

 methods of production and marketing. This cooperation has been 

 maintained by personal contact, since, in addition to the field agents
