,On June 5 a very heavy rain fell; and fearing that this had largely 
washed off the poison, we made a second application of the Paris 
green and water at the same rate as before. 
On June 17, we found on close examination that the larvae of the 
codling moth were still hatching and entering the fruits, which were 
at this time about the size of a small cherry. Wishing to make our 
application as thorough as possible, we sprayed the trees again on 
the following day, using one ounce of Paris green to ten gallons of 
water; applying the mixture this time with the so-called Field force 
pump fitted with the ‘‘Boss” nozzle. We found this apparatus very 
satisfactory. ‘The liquid left the nozzle in a thin sheet, which ex- 
panded in width as it rose in the air, and soon became broken up 
into a fine spray. By the time it reached the height of the tree top 
it was so finely distributed that it was necessary to hold the nozzle in 
one position for a considerable time before the water commenced 
dripping from the leaves. The nozzle could be held in the hand, 
dispensing with the pole, and by waving it to the right and left the 
foliage of the tallest apple trees in the orchard could be wet in one or 
at most two minutes, with very little waste of the liquid. 
Asthe apples began to drop in August, the windfalls were collect- 
ed and examined, under the sprayed trees, and those not sprayed, 
and the number of sound and wormy fruits counted. Oct. 5 and 6 
the remaining fruit was picked, and assorted, and counted in the 
same way. ‘The whole number of sound and wormy fruits yielded 
by each tree and the per cent. (fractions omitted) of wormy fruits 
upon each was as follows:

consisting of four pounds common yellow hard soap, one gallon ker-
