Thanks to Slingerland's pic- 

 tures we have this arch-enemy 

 of all good peach trees before

 evil doings, the latter written 

 so plainly that no child can fail 

 to read them. The children 

 should be asked to keep a sharp 

 lookout about their peach trees, 

 and all the trees in the neigh- 

 borhood in fact, because one old 

 stub may grow borers enough to 

 stock a large area, and gather 

 specimens of the different stages 

 for the school collection. 



To facilitate this work the life 

 story may be told in a word, as 

 follows : The moths, somewhat 

 resembling steel-blue wasps, 

 emerge from their cocoons on 

 the peach trees from late June 

 to early September (for latitude 

 of New York ; earlier in the south 

 and later farther north) and dur- 

 ing this time lay their eggs on 

 the trunks of peach and plum
