to plant a]~»proximately 6,700 acres. The control of this seed rested 

 largely with the United States Department of Agriculture, whose 

 experts were anxious to preserve a pure strain of this desirable type. 

 In order that there might be no admixture of the Pima and Yuma 

 strains, it was determined to restrict the planting of Pima seed to a 

 definite territory within the \'alley, to have this cotton ginned sepa- 

 rately from Yuma cotton, and to prevent the planting of any of this 

 seed within any territory which was contiguous to plantings of Yuma 

 cotton. The Tempe Cotton Exchange administered the distribution of 

 Pima seed to growers in a limited district south of Tempe. No Pima 

 seed was planted outside of this district and no Yuma cotton was pro- 

 duced within the arbitrary boundaries of this restricted area. In 

 order that tliere might be no misunderstanding as to the purposes and 

 provisions of this plan, every cotton grower who secured Pima seed 

 through the Tempe Cotton Exchange executed a contract which was 

 designed to continue the control of l^ima seed by the Tempe Cotton 

 Exchange. A copy of this contract follows :
