There are several other methods used in setting out plants, particularly by the New Jersey growers in their soft, sandy soils. One of the simplest planting machines is a lath or stick about the length of a cane, one end of which is two inches wide and distinctly concave; over this concave end a piece of soft leather is tacked. As the boy drops the plant as nearly as possible in its proper place, the man following simply pushes it into the ground by dropping the leather-covered staff over the root-end of the plant. A second thrust is made to force the soil around the plant. More elaborate tongs and planters are used in some places. Cultivation.—The first operation in the cultiva- tion of the sweet-potato is ordinarily the splitting out of the middles. A round trip is made with a one-horse plow, throwing against the sides of the ridges the additional soil left undisturbed in mak- ing the ridge. This is done within a week from planting time, or as soon as convenient, and before weeds have started. It is followed before weed- growth begins, and usually within two weeks of planting, by the first cultivation. The cultivator used by the writer is an ordinary five-tooth garden cultivator of the Planet Jr. type, havi
