This is a plant abhorred by everything but man and the tobacco-worm. Its use for chewing and snuffing is happily becoming more and more offensive to refined society, and we hope it may, after a long struggle, go out of use. For those who will cultivate it as an article of commerce, the following brief directions are sufficient. Burn over a small bed, on which sow the seed early in March. When the leaves are as large as a quarter of a dollar, transplant them in deep, rich soil, or on new land, in rows three feet apart each way, or four feet one way and two the other. Tend as cabbage. It is necessary, twice in the season, to destroy, by hand, the large green worms that feed on this plant. When the plants are from two and a half to three and a half feet high, according to the richness of the soil on which they grow, pick out the head or blossom-buds, except in the few plants you would have go to seed. Pinch off also the suckers, or shoots behind the leaves, as they come out. When the leaves are full grown and begin to ripen, which is known by the small, dusky spots appearing on the leaves, cut up the stalks and lay them down singly to wilt; when they are thoroughly wilted, lay them together, that they may sweat for forty-eight hours, then hang them up in a tolerably tight room to dry--hang across poles, one on each side. A sharp stick put through the but of the stalks and laid over the pole, leaving one stalk on each side, is a very good method. When it becomes well dried, pick off the leaves, and tie the stems together in small bunches, and pack away in hogsheads or boxes, in a dry place. We recommend to every agriculturist to cultivate a little tobacco--not for himself or others to chew, snuff, or smoke, but to use in destroying insects. A strong decoction, used in washing animals, will destroy lice on horses and cattle, and ticks on sheep. Tobacco-water applied to plants, or trees, will effectually destroy all insects with which they may be infested. Boil tobacco-stems or stalks, or the refuse-tobacco of the cigar-makers, until you make a strong decoction, and apply with a syringe, or in any other way, and it will prove more effectual than anything else known. Tobacco-stems, stalks, or leaves, laid around peach-trees in the month of May, will protect them from the attacks of the borer. This is also a good manure for peach-trees. TOMATO.
