154 THE CULTCEE OF THE GRAPE. 



under }3art of the leaf next to the one last eaten ; it is 

 usually of the same color as the leaf, and, xinlesa you 

 observe carefullj^, it will escape you. 



The thrips, small white insects that infest the under 

 side of the leaves, are not so injurious as would seem by 

 the spotted appearance of the leaf. Smoking, or syring- 

 ing with tobacco- water, will (jestroy them; they injure 

 the looks of the vine, giving the foliage a diseased ap- 

 pearance. Wide-mouthed bottles hung swnongst the 

 branches, (one every two square feet.) and filled with 

 sweetened water, will collect and destroy large quantities 

 of moths, and other insects. These will require to be 

 emptied every few days, or the dead insects on the sur- 

 face removed. '• 



In the grapery, the two years past, the common red 

 caterpillar has been exceedingly annoying. The white 

 moth lays its eggs on the under part of the leaf, and the 

 first notice you have of the young is when you discover 

 small spots eaten in the leaf; on examination, you will 

 now find the young caterpillar, one fourth of an inch in 

 length, spread over the leaves ; you must destroy all you 

 can find at once, and, every day, examine the vine anew; 

 notwithstanding all this care, some. of them will pro- 

 bably escape you, and grow to a good size. If these are 

 very numerous, and are on more than one or two vines, 

 it will be best to fumigate the grapery with tobacco 

 leaves, or stems. This will be necessary, if thrips, or the 

 apliis, or green fly appear in the house. In smoking, care 

 must be had that the foliage is not injured by the heat 

 from the tobacco ; this should be moist, so that it cannot 

 burn with a blaze ; embers and ashes should be placed
