The fruit from the unsprayed plat was 53.05 per cent wormy. 

 That of Plat III, sprayed twice, was 12.41 per cent wormy, showing 

 a gain of 40.64 per cent for two sprayings, and Plat I had 2.87 per 

 cent wormy pears with 97.12 per cent sound, realizing an increase of 

 50.18 per cent sound fruit over the unsprayed trees. 



PROFITS. 



The 10 trees in the unsprayed block, Plat II, Table XXXVIII, gave 

 a yield of 4,774 sound pears. Allowing 150 pears per box this would 

 give 31.82 boxes of shipping fruit. The net price this year for pears 

 shipped east was about 80 cents per box. Taking this as the price 

 for all the sound pears shows a total of $25.45 returns from the 10 

 trees not sprayed. Counting all windfalls after July 3 and all the 

 w r ormy fruit picked from the tree as fit for drying there were 7,939 

 such pears, or approximately 2,540 pounds, which would make 362
