CULTURE OF THE GRAPE. 311 



ca. Mix this with boiling water in which half a pound 

 of tobacco has been steeped, and then wash every part 

 of the cane at the season just prior to starting its growth. 

 A solution of one pound of potash in two gallons of 

 water is also effectual in killing the insects and destroy- 

 ing the eggs. So complete is our control of all the essen- 

 tial conditions, that we may safely say, that the grape- 

 crop, under glass, is the most certain of all fruit-crops. 

 If the crop has been injured by diseases, it is a certain 

 proof of culpable neglect: if there is a partial or total 

 failure of the crop, it arises from' circumstances which 

 might easily have been prevented. Considering the cer- 

 tainty and the ease with which the grape may be thus 

 grown, and the very important fact that it retains its high 

 quality under glass, in striking contrast, for example, with 

 the peach, we may conclude that no other fruit is so well 

 suited for glass-culture as the grape.
