56 NEW AMERICAN ORCHARDIST. 



shaken over a tree, distributes the lime amongst the leaves, 

 and the slugs are speedily destroyed. A man may go over 

 a large tree in a few minutes. 



SUBS. 5th. WASPS. Mr. Bartram has recommended, 

 for the destruction of wasps, which devour and puncture the 

 grapes in vineyards, that shallow vessels, containing sugar 

 and water, or molasses and water, should be placed on the 

 windward side of the vineyard. The sweet perfume at- 

 tracts them from a great distance from the leeward ; they 

 are thus destroyed, by partaking inordinately of the 

 liquid. 



Mr. Knight has informed us, that the wasps disappeared 

 from his vine house, after he had surrounded it in part 

 with a hedge of the yew tree. 



For the destruction of some other varieties of insects, 

 see APPLE, PEAR, PEACH, and PLUM. 



SUBS. 6th. THE WHITE MEALY INSECT. This insect 

 is described by English writers as an insect of a most per-

 it is little known. I must refer to them for the remedies. 



" Take half a peck of quick lime, half a pound of flour of 

 sulphur, and a quarter of a pound of lamp black. Mix the 

 whole together with as much boiling water as will form the 

 ingredients into a thick paint. This composition is recom-

 which are infested with the white mealy insect, having 

 previously removed the moss and loose bark by scraping 

 them off with a strong knife, or some other instrument 

 adapted to the purpose. 



" In using the composition, it will be most efficacious if 

 applied in a warm state, or something more than blood 

 heat" Lindley. 



On young trees, Mr. Lindley further informs us, " vine- 

 gar will effectually destroy this insect; but would be too 

 expensive to be applied when the trees are large." 



SUBS. 7th. THE ROSE BUG. These insects have of 

 late proved very destructive, by devouring the leaves, not 

 only of rose bushes, but also of the cherry tree, and various 

 other trees ; and rewards have been offered by the Massa- 

 chusetts Horticultural Society, for some easy and eflfec-
