Flea-Beetle, continued. 



Remedies. There are no reliable preventives or reme- 

 dies. Arsenites applied dry while the dew is o"n are best.

 same manner, are more or less effective. Tobacco decoc- 

 tion used very liberally. Wood-ashes applied liberally. 

 Sometimes these injure the plants. Kerosene emulsion 

 thrown with great force agrinst the plants. Calomel, 

 mixed with flour or ashes. The same remedies apply to 

 other flea-beetles.
