 C'f Casa Grande beans were planted July 20, 1915. Rows were 

 three feet apart in all plots, and plants were thinned to thirty-six, 

 twenty-four, twelve, and six inches apart. One check plot was left 

 without thinning. Table l.XXII records the results, the best yield 

 being obtained from the j^lt^t that was not thinned. Damage bv 

 grasshoppers, however, so hampered the growth of beans in this 

 test that data obtained are' not especiallyi valuable.
