CULTURE OF THE GRAPE. 259 



stems. Upon careful search, I discovered the lice, which 

 were nearly of the color of the bark of the vine, partly 

 embedded in a little crevice of the bark, and arranged one 

 behind another in a line. They drew great quantities of 

 sap, as was apparent by their exudations, by which the 

 ants were attracted. Further observations were arrested 

 by a fire, which consumed the house, and the vines that 

 were trained to it." 



"Wherever there is danger of any of these or other 

 forms of bark-lice, the solution of potash will be found an 

 effectual remedy. It may be freely applied, without re- 

 gard to the drippings, as that which falls to the ground 

 will not be lost. 



GALL.S. 



The leaves of the vine are sometimes seen to have ex- 

 crescences, which appear in the month of August. This 

 is undoubtedly caused by the sting of some insect, or gall- 

 flv, depositing a poison, and making a puncture for the 

 lodgement of its young. The effect upon the vine is very 

 slight ; but, lest the evil should increase, it would be well 

 to collect and destroy the leaves so punctured, before the 

 eggs are hatched.
