it to fall. When full fed it lays up in crevices 

 of the bark and other shelter for the winter, 

 assuming the pupa state.

fruit and burn it, or feed pigs with it as soon 

 as it falls. Strips of cloth or sacking may be 

 tied round the trunk of the trees near the base, 

 and the caterpillars will lay up for the winter 

 underneath the bands. Commence in July and 

 continue for a week after the fruit is gathered, 

 examining the bands every ten days or so, and 

 destroying caterpillars or pupa?. Codlin-grub 

 traps, consisting of several pieces of wood fas- 

 tened together by a screw in the centre and 

 held apart with thin laths, may be hung against 

 the trees and examined periodically as in the 

 other case. Paris -green and London -purple 

 are often employed with great success against 

 the Codlin Grub. One pound of either should 

 be well mixed in 200 to 250 gallons of water, 



thoroughly stirred, and then applied to the 

 trees as soon as the blossoms fall, in the form 

 of a fine spray, till the leaves and fruits are just 

 moist, but not dripping. The operation may be 

 repeated when the fruits begin to swell. Both 

 ingredients are highly poisonous, and should be 

 used with carej they get washed off by rain 

 long before the fruit is ripe. Properly con- 

 structed spraying-machines of different sizes are 

 readily obtainable, and should alone be used. 

 Sulphate of copper at the rate of 1 lb. to 

 160 gallons of water may be employed in the 

 same way as Paris-green. 



Earwigs. — These are very destructive to 

 Peaches, Nectarines, and other soft fruits. For 

 remedies see under Buds and Flowers. 



Grape Moth (Ditula angustiorana). — When 

 the wings are expanded, this moth only measures 

 J inch to f inch. The fore-wings of the male 

 are grayish-yellow, with various brown mark- 

 ings. Those of the female are more of a reddish- 

 yellow hue, with reddish-brown markings. The 

 caterpillar is of a dirty greenish-gray, with a 

 pale -buff shining head. It is found on most 

 trees, tying together and devouring the leaves, 

 but for some years past has proved injurious to 

 ripe grapes by tying them together and piercing

for a short way into the pulp, causing several 

 berries to decay. 



Remedy. — Like the larva? of many other 

 moths, the caterpillar in this case suddenly lets 

 itself down with a thread when alarmed. Ad-
