The thrip, a small, rather three-cornered, whitish-green insect, has of late been very troublesome, as they eat the under side of the leaves of some varieties, especially the Delaware and Norton's Virginia, when the leaf will show rusty specks on the surface, and finally drop off. It has been recommended to go through the vineyard at night, one man carrying a lighted torch, and the other beating the vines, when they will fly into the flame, and be burnt. They are a great annoyance, and have defoliated whole vineyards here last fall. Another leaf-folder makes his appearance about mid-summer, making its web on the leaf, drawing it together, and then devouring his own house. It is a small, greenish, and very active worm, who, if he "smells a rat," will drop out of his web, and descend to the ground in double-quick time. I know of no other plan, than to catch him and crush his web between the finger and thumb. The aphis, or plant louse, often covers the young shoots of the vine, sucking its juices. When a shoot is attacked by them, it will be best to take it off and crush them under your feet, as the shoot is apt to be sickly afterwards, any way. The grape vine sphynx will be found occasionally. It is a large, green worm, with black dots, and very voracious. Fortunately, it is not numerous, and can easily be found and destroyed. There are also several caterpillars--the yellow bear, the hog caterpillar, and the blue caterpillar, which will feed upon the leaves. The only remedy I know against them is hand picking, but they have not as yet been very numerous, nor very destructive. Wasps are sometimes very troublesome when the fruit ripens, stinging the berries and sucking the juice. A great many can be caught by hanging up bottles, with a little molasses, which they will enter, and get stuck in the molasses. BIRDS. These are sometimes very troublesome at the time of ripening, and especially the oriole is a "hard customer," as he will generally dip his bill into every berry; often ruining a fine bunch, or a number of them, in a short time. I have therefore been compelled to wage a war upon some of the feathered tribe, although they are my especial favorites, and I cannot see a bird's nest robbed. However, there are some who do not visit the vineyard, except for the purpose of destroying our grapes, and these can not complain if we "won't stand it any longer," but take the gun, and retaliate on them. The oriole, the red bird, thrush, and cat bird are among the number, and although I would like to spare the latter three, in thankful remembrance of many a gratuitous concert, the first must take his chance of powder and lead, for the little rascal is too aggravating. A few dry bushes, raised above the trellis will serve as their resting place before they commence their work of destruction, where they can be easily killed. FROSTS.
