THE VINEYARD.

the grape-vine flea-beetle which lays its eggs on the underside 

 of the leaves. Small brownish larvae are hatched, which eat 

 the leaves, then drop to the ground and change to the pupa 

 form, from which in about three weeks the perfect beetle 

 emerges. The beetles may be collected by hand, and the 

 vines dusted with powder or sprayed. We also give here one 

 of the leai-rollers which are found on so many vines and trees.

This grape-vine leaf-roller eats the leaves. The adult is 

 a dark-colored moth with two white spots on each of the 

 two hind wings. The larva rolls up a leaf and stitches it 

 together, as shown in figure 67. Poison by spraying with 

 Paris green in water, applied in early spring. 



The principal diseases of the grape are mildew and black 

 rot, which are prevented by spraying. 

 SUGGESTIVE : 



Grape leaves are suitable objects to draw in outline. Notice the woolly- 

 leaved Roger's varieties (ihe southern Fox grape) and a'so the thin 

 smooth -leaved kind lik; Clinton the northern type.
