 are but little injured. 



Remedies. This suggests one of the best means of handling 

 this pest to be the growing of early varieties, such as Alaska, 

 American Wonder, Gregory's Surprise, Nott's Excelsior, and 

 McLean's Little Gem. If the crop is known to be infested, clean 

 up the vines and burn them as soon as it is picked. Dr. Fletcher 

 has made some experiments in spraying for this pest which seem 

 to promise success. One pound of Paris green to 100 gallons of 

 water was used, and it is advised to spray three times; the first 

 when the blossoms begin to fall; the second, a week later; and the 

 third ten days later than that.
