acre. The best amount to apply every year seems to be 10 to 15 loads 

 per acre. This treatment gives a four-year average yield of 83 barrels 

 per acre and an income of $147. Larger amounts applied every year 

 are not so beneficial. Fifteen to twenty loads seems the best amount 

 to apply once in two years, for although the yield appears larger for smaller 

 amounts, the income per acre increases with the amount of manure applied, 

 being $124.23 for 5 to 10 loads, $127.28 for 10 to 15 loads, and $147.12 

 for 15 to 20 loads.

orchard pests and DISEASES 



Ontario county seems to have its full share of orchard enemies. Table 

 29 gives 15 of those reported, with the number of orchards in which 

 they occur. The blister mite appears to have been the most trouble- 

 some at the time this survey was made, having been reported as occur- 

 ring in 305 orchards. Among the chewing insects, the codling moth, 

 tussock moth, pistol and cigar case bearers, bucculatrix, tent caterpillar, 

 and curculio were and probably are most prevalent. Of these the codling 

 moth is the most injurious, with the tussock moth a close second. The
