AND RURAL ECONOMIST. 327 



scription of this very pernicious insect is thus given by pro- 

 fessor Say, of Philadelphia : ' Hoary ; above, light-brown, 

 with two broad white fillets. Inhabits the United States. 

 Body, white; eyes, fuscous ; a small spot on the vertex, and 

 another behind each eye, light-brown ; antennce, moderate, 

 slightly tinged with bluish ; thorax, light brown, with two 

 broad, white lines, approaching before ; eZ?/?ra, light-brown, 

 irregularly punc^^ured ; a broad, white, longitudinal line on 

 each, nearer to the suture than to the outer edge. Length, 

 from one-half to seven-tenths of an inch. A very pretty in- 

 sect. In the larvce state, it is very injurious to the apple- 

 tree, boring into the wood.' — Journal of the Academy of Sci- 

 ences, Phil. vol. i:i. p. 409. 



Professor Say, in a letter to Jesse Buel, Esq., says, ' You 

 state that it leaves the pupa, and becomes perfect in the lat- 

 ter part of April, and that the eggs are deposited beneath 

 the surface of the soil. These two circumstances ascer- 

 tained, I wojjld recommend the application, early in May, or 

 the latter part of April, of common bricklayer's mortar, 

 around the base of the tree, so as to cover completely the 

 part, and its immediate vicinity, where the deposit is made. 

 This preventive was successfully employed by Mr. Shot- 

 A f ]] against the attacks of the peach-tree insect, (see Ameri- 

 can Farmer, vol. vi. p. 14,) and I see no reason why it should 

 not be equally efficacious in the preservation of the apple- 

 tree.' — Memoirs of the Neiu York Board of Agriculture, vol. 

 iii. p. 479. 



The Massach?/ setts Agricultural Repository, vol. v. p. 360, 

 contains a paper on this insect, by John Prince, Esq., by 

 which it appears that worms of this kind are got rid of by 

 * digging round the tree, and clearing away the earth to the 

 roots, and then with a sharp-pointed knife, a chisel, or a 

 gouge, end a small wire to probe, if they are deep in the 

 tree, they may easily be destroyed.' After taking out the 

 worms the wounds should be covered over with graftinor-clay 

 and a large proportion of dry wood ashes mixed, and the 

 earth then returned to the tree. The process for cleansino- 

 the trees from borers should be performed in the spring, as 

 soon as the frost is out of the ground, or at least before the 

 month of June, as the perfect insect escapes before that 

 time. 



Slug-iuorm, or Naked Snail. These reptiles appear on 

 the leaves of fruit-ti-ees in the month of July. Professor 

 Peck has ascertained that they are the progeny of a small
