lluBBEU Fumes as an Insecticide. 

 — At a recent meeting of the Board 

 of Agriculture in Massachusetts, it 

 was asserted that fumes of burning 

 rubber was an e.xcellent insecticide. 

 Mr. Briggs has experimented with it, 

 taking an old rubl er boot and putting 

 it on a bed of coals in an old pan, and 

 carrying it about under his peach trees 

 and grape vines ; and found it drove 

 away the rose-bug entirely. It also 

 drove away the codling moth from 

 the apple trees. He applied it early 

 in the morning while the dew was on. 

 One panful would do all the work on 

 forty trees, walking as fast as possible. 

 His theory is that the leaves retain the 

 smoke, which is disagreeable to the 

 insects. 



The Yellows. — Prof. Auger, state 

 pomologist of Massachusetts, has been 

 a strong believer in potash as a cure 

 for Yellow.s, but though he has used as 

 much as eight and ten tons a year of 

 ashes in his pe.ach orchard he cannot 

 report complete exemption. 



The Quince. — At the same meeting 

 Prof. Maynard commended high culti- 

 vation for the (^Hiince, which he said 

 was one of the very best fruits for can- 

 ning, and exceedingly healthful. He has 

 seen quinces of the orange variety, 

 jrrownso lartre that fifteen of them would
