the insects will soon assemble inside on the fliolasses, 

 when they are easily destroyed by a handful of burning 

 straw. 



The Peach -Tree Sorer. — This is a most destructive 

 insect when allowed to increase for a few years without 

 molestation. We have seen whole orchards of fine trees 

 ruined by them. They sometimes attack even young 

 trees in the nursery, and commit serious depredations on 

 their collar, rendering them in many cases quite unfit for 

 planting. Their multiplication should be prevented by 

 all possible means. The eggs are deposited in summer 

 on the base of the trunk, near the collar, where the bark 

 is soft. There they are hatched, and bore their way 

 under the bark of the tree, either in the stem or root, or 

 both, producing an effusion of gum. Where trees are 

 already affected, the proper course is, to remove the earth 

 from around the collar of the root, clean away the giim, 

 destroy any cocoons that may be found, trace the grub 

 through its holes in the tree, and kill it; then fill up 

 around the tree with fresh earth, and place a shovelful or 

 two of ashes around the base. One of the best orchards 

 in the vicinity of Rochester was at one time nearly ruined 

 by the prevalence of this grub, when it changed pro- 

 prietors, and the present one adopted and followed the 

 plan recommended above, until there is not the trace of 

 one left. The ashes or slaked lime should be applied 

 every spring, and at the end of summer may be scattered 

 about the tree ; both ashes and lime form an excellent 

 dressing for the peach. 



The Rose-Bug. — The eggs of this insect are laid in 

 the earth, where they are hatched, and from which the 

 bug emerges about the rose season. 



In some seasons and in some localities they appear like 

 grasshoppers in vast multitudes, and commit extensive 

 ravages, not only on the rose but fruit trees and all other 

 green things. Syringing the plants with diluted whale-
