ently scattered over the plants by using an old broom for a dus 

 or a Paris-green sifter. With a pailful of the lime, a man could 

 in a short time dust an acre of asparagus. It could best be 

 applied in the morning while the dew i> on. for Mien a portion will 

 adhere to the plants as well as to the grubs, and during the day or 

 days following, it will be constantly dropping down or blowing 

 about among the leaves and branches, thereby making the escape 

 of any of the larvae all the more uncertain. 



For the past sixteen years, Mr. Fuller had, according to his 

 statement, used lime as described, upon his asparagus beds, to 

 keep the insect in question in check, and it has done it so effectu- 

 ally that about one application every alternate season was suffi- 

 cient. Not only is lime cheap and readily procurable everywhere, 

 but it is of benefit to the asparagus roots. It- has also the addi- 

 tional merit as an insecticide, that it can be used upon the young 

 plants while they are being cut for market, for the destruction 

 of the first brood of larvae while Paris green or London purple may 

 not safely be employed. 



The Grapevine " Thrtps." 

 Frequent complaints are made of the damage done to grape- 

 vines, from an attack upon their leaves by the " Thrips." This is a 

 popular name — but an incorrect one as will be shown hereafter — 

 which has obtained widespread currency among vine growers for 

 some small (about an eighth of an inch long), slender, spindle- 

 shaped, parti-colored leaf-hoppers, which are very destructive to 

 the foliage of grapevines. They abound upon the leaves in their 

 three stages of larva, pupa, and perfect insect, in each of which 

 they are injurious. Their injury to the leaves is caused by punc- 

 turing them with their beak or proboscis and feeding upon the sap. 

 They are usually to be found upon the under surface of the leaves. 

 The punctures first produce small discolored spots, which are multi- 

 plied over the surface, and rapidly increase in size by their run- 

 ning together and by the greater suctorial power of the growing 

 insect. Later they become large brown blotches, which, if the 

 insects are numerous, extend over and embrace the entire leaf, 

 causing it to dry, — appearing as if scorched by fire, — to die, and 

 fall from the vine. As a consequence of this partial defoliation,
