send you two. The little wingless l)ngs are lively on the south 

 side of the trees though the snow is three or four inches deep 

 among the trees." The insects spoken of above were the wingless 

 females of the Canker-worm. 



Remedies. 

 We would advise a trial of a tin band, which consists essentially 

 of a band or circle of tin a few inches outside of the trunk of the 

 tree, held there by a circle of muslin attached to the tin at its 

 edge and drawn with a cord at the top, so as to fit the tree closely 

 and prevent the insects from getting up without going over the tin. 

 The tin is kept covei'cd with a mixture of equal parts of castor oil 

 and kerosene. As soon as they touch this they fall to the ground. 

 The muslin can be fastened to the tin by turning over the edge of 

 the tin before it is bent to a circle and inserting the edge of the 

 muslin and hammering them together. The tin should be about 

 three inches wide and long enough to stand out three or four 

 inches from the tree, when bent around it and fastened by 



rivets. The whole inner surface of the 

 tin is daubed with the mixture of castor 

 oil and kerosene. The mixture should 

 be renewed occasionally and the bands 

 kept on the trees until the moths dis- 

 appear. Fig. 3 shows the nature of the 

 \band and the way to attach it. Should 

 the trees be full of eggs or young cater- 

 pillars then spraying would have to be 

 resorted to. 



Mr. Partridge believes in thorough 

 work and sprayed, using one-half pound

 were injured. He speaks of the flower buds of his trees being 

 eaten, apparently before they open. This may have been done by 

 the Eye- SjJottecl Bud Moth; see Sta. Rept. 1888, p. 169, also 

 Rept. 1890, p. 128. The spraying should be done early enough 

 to catch the young worms before they do much damage to the 

 foliage. The time can be determined by watching a few clusters 

 of eggs and when they are hatched the mixture should be applied, 

 or to be safe two sprayings could be made, one just as the leaf 

 buds are bursting and another a week later. While the leaves are 

 young and tender we would advise a weak mixture, say one pound 

 to two hundred gallons. It is a great shock to a tree to loose its
