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 Il, Table XX XVITI, 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 
wormy fruit picked from the tree as fit for drying there were 7,939 
such pears, or approximately 2,540 pounds, which would make 362
