As will be seen from the foregoing table, there were counted from 

 Plats I, II, III, IV, and V, respectively, 3,825, 6,711, 5,275, 4,141, 

 and 6,518 apples, a total for all plats of 26,470. (In giving the 

 results from all of the other one-spray experiments presented in this 

 paper the one-spray plat is compared with the commercial lime- 

 sulphur demonstration; therefore, for sake of uniformity, the same 

 comparison is made in this experiment.) Plat I, which received the 

 commercial lime-sulphur treatment, shows for the individual trees a 

 range in percentage of fruit free from the codling moth of 91.75 to
