cocoons are loft in the crevices. 2d. Examine all liarrels, 

 bins, shelves, etc., where apples have been stored in cel- 

 lars or fruit-room. 3d. Place bandages of old cloth, car- 

 pet, or rags of any kind around the trunks and largo 

 branches of every tree, say by 1st of July, to trap the 

 worms; examine every week or two, and kill all worms 

 that have been trapped. 4th. Pick or knock off every 

 wormy fruit before the worm escapes, and destroy; })ick 

 up all that drop, and destroy in the same way. Recently 

 Paris Green h:is been used against the apple worm with 

 great success. The poison is- mixed with water and 

 sprayed upon the trees soon after the fruit sets. Tho 

 calyx eml of the fruit then points upward, and the poison 

 will lodge in the blossom end of the apple. The young 

 worms are poisoned as soon as they begin to eat into the 

 fruit Tlie summer rains wash the Paris Green from 

 the trees, so that even a chemical analysis will fail to 

 show its presence in the autumn. It is said that a small 

 amount of Paris Green, a tablespoonful to the barrel of 

 water is sufficient. The best way to spray large trees is 

 to place a barrel or cask containing the liquid on a plat- 

 foim wagon, which can be drawn through the orchard 

 by horses. The fluid may be thrown upon the trees by 

 any one of the several force pumps sold for that purpose. 



The Canlcer- Worm. — Tiie moths generally emerge from 

 the ground in March, though some rise during the late 

 autumn and winter months. The female has no wings, 

 but crawls u]) the tree, and lays her eggs on the branches 

 in May, in clusters of 60 to 100 in each; the little worms 

 fall upon the leaves, and, when numerous, devour them 

 all, leaving only the mid-ribs. They leave the trees when 

 about four wrecks old, and enter the ground. Their effects 

 are most visible in June, when the trees, divested of their 

 foliage, appear as if scorched by fire. 



As the female cannot fly, the great point is to prevent 

 her from crawling up; for this purpose various means liave
