een to twenty inches in depth. "1. In the fall plough deeply and subsoil plough, in all eight "EARLY GOODRICH POTATO." The illustration of a potato here with given represents the "Early Goodrich," which is celebrated, with superior cultivation, for being very early, large, white skin, smooth eyes, white flesh, of first quality, perfectly sound, solid to the core, keeps well, and is highly productive. Average yield on good rich soil, 300 bushels per acre. This and the following illustrations of potatoes were prepared by Mr. A. W. Harrison, of Philadelphia, a distinguished potato amateur. We furnish a fair idea of his mode of raising potatoes. "2. In early spring, plough and subsoil across the winter furrows; harrow and roll. "3. Mark out, as for corn, three feet apart each way, opening the furrows eight inches deep. "4. At the intersection drop a whole potato, the largest you have, and spread upon it a handful (about forty bushels per acre) of a compost made of eight parts of wood-ashes, four of bone phosphate of lime, four of fine-ground plaster, two of finely slaked lime, and one of salt; or, if preferred, three ounces of artificial fertilizer per hill. Then cover, roll, and spread 1,000 lbs. per acre of good artificial fertilizer. "5. As soon as the young plants appear, run the cultivator close to and between, but not over them, in each direction. Afterwards, and before the weeds come up, cultivate, both ways, with Knox's horse-hoe-so arranged as to cut as shallow as possible, and keep the surface entirely flat. Repeat this, at short intervals, three times. Then hand-hoe three times, still keeping a flat surface. Allow no hilling at any time, nor any weeds to grow. "6. As soon as the tops are dead, dig in clear dry weather with heavy five-tined digging forks; spread, under cover, to dry, and store in a cool, dark, dry, airy cellar, spreading half a pint of freshly-slaked lime in powder on each bushel of pota toes. "7. Gather and compost the dry tops, for application next autumn; then plough and subsoil-plough as before, for next year's crop. "The following are the advantages of this system of cultivation: "1. No possible entire failure of the crop. "2. No rot in healthy varieties. "3. The largest yield the soil and variety are capable of. "4. The largest proportion of large potatoes. "5. No degeneracy of varieties, but continued improvement. "6. No necessity for rotation of crops: the potato can be thus grown almost indefinitely on the same land, with, perhaps, at long intervals, a seeding to clover to maintain the supply of vegetable fibre in the soil. "7. No loss by late spring frosts. If the early growth is cut off, the dormant eyes will grow and the crop be saved. "If the materials for the compost cannot be obtained, topdress heavily in the fall, after ploughing, with barn-manure, but never use it in the season of planting. It may increase the crop, but tends to engender disease, especially in wet seasons. "Any further information on the subject will be cheerfully furnished on application. "If you wish liberal crops you must give liberal culture." FORCING POTATOES IN HOTBEDS. Potatoes may be forced in a great variety of ways. Those who attempt to mature Potatoes in frames, will of course provide such of the earliest kinds as are not inclined to produce large tops. Potatoes may be forwarded in growth previous to being planted in the beds, by placing them in a warm, damp cellar. Some forward them in pots and boxes, and afterwards mature them in a hotbed; others plant them in the bed at once, in which case the bed should be moulded from fifteen to twenty inches deep, and the heating materials should be sufficient to keep up a moderate heat for several weeks. Perhaps the most convenient way to force Potatoes in this climate, is to provide pots for the purpose, and plant one set in each pot, and place them in a warm cellar till a bed can be prepared. While the tuberous roots are forming, and before they fill the pots, prepare the beds for maturing them, and then bury them in the mould with the balls of earth attached to them. The beds should be kept free from frost, and air should be given at every opportunity. The common round Potatoes may be forwarded, by laying them thick together in a slight hotbed in March, and when they are planted in the borders, a quantity of comb-maker's shavings may be deposited in each hill; this will greatly promote their growth. POTATO-GROUND MARKER. The accompanying illustration represents a gauge-marker, for marking out either potato ground or corn ground. It is drawn by two horses, and makes three marks at one through. The three runners are each about four feet long, eight inches wide, and two inches thick. The two outside runners can be moved towards or away from the middle runner, and secured to the slats that extend through all the runners. The slats are four inches wide, of hard wood, and one inch thick. A wooden pin secures them rigidly in the middle runner, and iron pins in the outside runners. A tongue belonging to some light carriage can be used with such a marker. The braces of the tongue are secured to raves bolted to the slats, as shown by the figure. It can be constructed with a seat, or not. On sod ground a seat will be necessary, as the weight should be increased in order to make a plain mark. The illustration will show how the handles are to be attached. The gauge-marker has a small chain attached to the outer end, which should run in the last mark made by the runner. When the marker is turned around, the gauge is laid over on the other side of the marker. TRUE'S POTATO PLANTER. The illustration herewith given represents a machine for making the furrow, cutting the potatoes, dropping the pieces, covering the seed, and rolling the ground, all at one operation,. in a workmanlike manner. It was invented only a few years since, by J. L. True, Garland, Maine. We have seen it operated with one horse, where it planted potatoes with great dispatch and accuracy. Where a farmer plants several acres of potatoes, such a planter will relieve workmen of much hard labor. A STEEL CULTIVATOR TOOTH. The following illustration represents one of the best kinds. of cultivator teeth that we have ever met with for cultivating potatoes. They are bolted to the wood-work of cultivators, with strong bolts passing through the iron flanges or palms on the upper end of the standard. The steel plates are bolted to the cast-iron standards. When the earth is to be turned towards the growing plants, the teeth are attached with |
