Like some other vegetables, these are generally supposed to require special soil and situation to do well, but with plenty of manure and good cultivation they can be raised of fine size and quality in any garden. As described in the chapter on hotbeds, the old potatoes are planted in a warm bed, about the first of April, and when the ground is prepared, these are taken up and the sprouts broken off close to the potato. The potatoes should be buried two or three inches deep in the bed, which will give each shoot a bunch of fine roots when it is broken off. When the nights are warm, and the trees well out in leaf, plow a double furrow where the row of sweet potatoes is to be; that is, run the plow each way in the same furrow; then fill in two or three inches of fine manure, and plow the furrows back again, forming a ridge over the manure. In the centre of this ridge plant the sets about one foot apart; they must be kept well cultivated, and the running vines must not be allowed to strike root into the soil, or they will form lots of small potatoes, and none large enough for use; some gardeners keep the vines coiled round the central plant, but the easier way is to throw the vines from two rows together, then cultivate the side left bare, and throw them back again, cultivating the other side; after the first time they need not be moved but once for each cultivation, as the blank side can be cultivated and the vines thrown over on it, leaving the other side free, which can be cultivated first the next time it is done, and the vines thrown back. Throwing the vines over can be done very quickly by running a rake handle or long light pole under them, and throwing its whole length of them over at once: they can be dug as soon as large enough for use, by scraping the dirt away from the side of the hill, the potatoes pulled off, and the vines left to form more. The whole crop should be dug as soon as the vines are blackened by the first frost, and spread out in a cool dry place, where there will be no danger of their freezing. On account of the vines taking so much room, the rows should be at least five feet apart. SAGE. A dozen roots or more of this herb should be planted in some part of the garden where it will not be disturbed by the plow, or if this cannot be done readily, the roots can be taken up when the plowing is done, divided and reset, which would probably raise a larger and finer crop of leaves than allowing them to stand in the same place year after year. The crop should be cut off a few inches above the ground, as soon as it has made its growth and before it begins to bloom. The shoots will again start to grow, and two or three crops can be cut in a season; the cut tops can be tied in bunches and hung to the rafters, or spread thinly on the floor of a cool loft or garret.
