"In the n<'\\ wood, the plant-i 1 constituents used per acre are greatest in the

 A historical account is given of early orcharding in New York and of the introduc-

Phases of orchard management in "Wayne County as discovered by an 

 orchard survey, J. Craig ( West. X. )'. Hort. Soc. I'm,-. 1905, pp. 54 >'■'/. figs. 6).— 

 Ina fruit survey which was made in Wayne County it was found that the average 

 yield of apples f<»r 4 years in orchards where the trees were planted 30 ft. apart each 

 way was 184 bu. to the acre. When the distance between the trees ranged from .".I 



h\ :;i to 35 by 35 each way the average yield was 222 bu. per acre ami when the 

 distance ranged from 36 by 36 to 40 by 40 ft. each way the yield averaged 229 bu. 



per acre. 



Imperfect drainage was found to be a frequent cause of failure, in whole or in part, 

 in many western New York orchards. The matter of ownership appeared to have 

 an important bearing on productiveness of orchard-. The average yield in orchards 

 managed by the owners was 210 bu. per acre and in rented orchards 174 l»u. per 

 acre. There was also a considerable difference in the yield from sprayed and 

 nnsprayed orchards. 



In 66 sprayed orchards the average yield was l' s <> bu. per acre and the selling 

 price $2.02 per barrel, while 107 nnsprayed orchards yielded at the rate of 253 bu. 

 per acre and sold at an average price of $1.80 per barrel. These figures indicate a 

 difference of about $14.84 per acre in favor of spraying. The trees were sprayed 

 only once or twice, rarely three times, and no Bpecial effort was made to make it 

 thorough and efficient
