A gentleman obtained from a single root, thus planted, very near forty pounds' weight of large potatoes; and, from almost every other root upon the same plot of ground, from fifteen to twenty pounds' weight; and, except the soil be stony or gravelly, ten pounds, or half a peck, of potatoes, may almost be obtained from each root, by pursuing the foregoing method. 1021. _Use of the Dandelion._--This is an excellent salad, and a good green. Where it grows as a weed, cover it early in the spring, with rotten tan, or decayed leaves; it will soon come up. 1022. _Preparations for Carrots and other winged Seeds._--Take two bushels of dry loamy earth, finely sifted; to which add one bushel of bran, and a sufficient quantity of carrot seed, cleaned from stalks, and well rubbed between the hands; all which thoroughly mix together, and drill (or sow). The carrot seed will stick to the bran, which, with the earth, will be regularly discharged. 1023. _To raise a Salad quickly._--Steep lettuce-seed, mustard, cresses, &c., in aqua vitæ. Mix a little pigeon's dung with some mould, and powdered slaked lime. In forty-eight hours the salad will be produced. 1024. _Important Discovery relative to the Preservation of Grain._--To preserve rye and secure it from insects and rats, nothing more is necessary than not to winnow it after it is thrashed, but merely separate it from the straw, and to stow it in the granaries, mixed with the chaff. In this state it has been kept for more than three years without experiencing the smallest alteration, and even without the necessity of being turned to preserve it from humidity and fermentation. Rats and mice may be prevented from entering the barn, by putting some wild vine or hedge plants upon the heaps; the smell of the wood is so offensive to these animals, that they will not approach it. The experiment has not yet been made with wheat and other kinds of grain, but they may probably be preserved in the chaff with equal advantage. It must however be observed, that the husks and corns of rye are different from most other grain. It has been sown near houses where many poultry were kept, for the purpose of bringing up a crop of grass, because the poultry do not destroy it, as they would have done wheat, oats, or even barley in the same situation.
