Fish-brine for Exterminating the Aphides. Brine and 

 salt must be used around fruit-trees with extreme caution, 

 lest the trees be killed before the insects are dispatched. 

 We have frequently read of the successful use of weak fish- 

 brine, sprinkled among the leaves and tender branches ; but 

 we have never used brine in any form, as we dare not, even 

 when it is much diluted. Salt and brine will often kill 

 trees and plants in a few days, without affecting a single in- 

 sect in the least. It is a mistaken idea that salt spread 

 around fruit-trees will repel or exterminate insects or 

 worms of any kind, unless it is applied in sufficient quan- 

 tities to destroy the last vestige of vegetation. Brine will 

 doubtless destroy the aphides when sprinkled on the leaves 

 of trees. But it must be much diluted, or the saline mate 

 rial will kill every leaf. Whenever brine is employed, the 

 twigs and leaves should be sprinkled with water soon after 

 the brine is applied. Brine or soap will perform its work 

 on the tender lice in a few minutes, when fresh water should 

 wash the leaves clean. 



The Sulphur Remedy. Some pomologists, both in Amer- 

 ica and in the Old World, have written favorable accounts 

 of the use of sulphur on apple-trees for exterminating the 

 aphides and some other depredators. The sulphur can be
