On high-priced truck-garden land, closer planting may be advis- able. The tubers are planted with an automatic cutting, dropping, furrowing and covering machine. The fields are tilled ten to fifteen times. With the good preparation of land and efiicient tools, this extent of tilling is not laborious nor expensive. Level culture is practiced, but considerable ridges are formed by the time the vines cover the ground. A riding double-row cultivator and one- horse weeder are used. Tillage invariably begins within a week after planting, by following the potato-row lines. The first and second times over, very narrow teeth are used, set deep. The third and fourth tillings are made as soon as the rows can be followed, working deep and very close to the plants. Immediately following the fourth cul- tivation, the weeder is used, as a rule, running twice over the field, crosswise and lengthwise, the lengthwise treatment pulling the plants up straight so that subsequent working is not interfered with. Seven-inch side teeth are now used on the cultivator, throw- ing a small, sharp ridge directly on each row, burying the weeds. The fields are hand- weeded once or twice; and, in this operation, all weak, diseased or prematurely ripen- ing potato plants are pulled up, being. Fig. 756.

Spraying is accomplished by means of a two- wheeled geared machine, developing to eighty pounds pressure and carrying the nozzles ahead of the wheels. On eighteen acres in 1906, there were used 331 barrels (of fifty-five gallons) of Bordeaux mixture, entailing a co
