Insects and Sprays 169 



Do not fail to destroy every tent-caterpillar you 

 see. They multiply too rapidly to take chances 

 with even one. 



To kill weevils in beans, peas, chestnuts, etc., 

 put the legumes or nuts in a barrel which has no 

 cracks and pour over them a teacupf ul of bisulphide 

 of carbon. Then cover tightly with a wet blanket 

 or other woolen cloth for twenty-four hours. Do 

 not breathe the fumes and be careful not to have 

 fire or lights anywhere near. 



The browntail moth is a white moth with a 

 brown abdomen. It lays its eggs usually on the 

 under side of the leaf during July, which hatch into 

 caterpillars and do their damage the following 

 spring. Four pounds of arsenate of lead to fifty 

 gallons of water is an adequate spray for their 

 death, and the trees should be sprayed in August 

 soon after the eggs hatch and again when the 

 leaves open. 



Aphis, San Jose scale, apple-scab, and fly-speck 

 disease of apples should be spread with a solution 

 of commercial lime-sulphur, one gallon to eight 

 gallons of water in the spring before the buds 

 open and again in the fall after the leaves fall off. 

 Persistency is the keynote of success in spraying.
