Farmers who have soil that is both rich and deep can find profit in growing horseradish on a large scale, in connection with early peas, beans or sweet corn. The sets are planted in May, in the rows between crops, and after the crops are removed the horseradish makes its main growth. It is perfectly hardy, and comes on rapidly during the late summer and autumn months. Where the ground is not strong enough to produce large roots the first year, the business will not prove very remunerative. =The Sets.=--Horseradish sets are made by cutting small roots (1/4 to 1/2 inch in thickness) into pieces 6 or 8 inches long. The upper end is cut square off; the lower end with a slope. This is to get them right end up at planting time. The small roots are available in quantities in the autumn, when the large roots are trimmed for market. The sets are kept in sand during the winter, or buried in the open ground, in a carefully-marked spot, where they can be easily found in the spring. If planted 2 feet apart in rows 3 feet apart, each plant will represent 6 square feet of space, and, hence, about 7,300 sets will be needed for an acre. The method of planting is to strike out rows, and with a long dibber or crowbar make holes 8 or 10 inches deep. A set is dropped into each hole and the earth pressed about it.

Little further attention is needed. The roots should be lifted the same year, in December, and stored in an earth-covered heap or pit, or else in sand in a root cellar. The small lateral roots should be saved for the next year's sets. There is a good demand for horseradish, both wholesale and retail; but prices should be ascertained before going into the business in a large way. Good roots, after trimming and washing, should weigh half a pound or more each. PARSNIP. The cultural requirements of the parsnip are quite similar to those of the carrot. Any soil that is deep mellow and moderately rich may be used for parsnips. Fresh manure is to be avoided, as it makes the roots rough. [Illustration: Mammoth Sandwich Island Salsify as Bunched for Market.] The seed should be planted in early spring, while the ground is moist, as it germinates very slowly. It should be covered to a depth of half an inch, and the soil pressed down firmly. The plants must be thinned out to stand 3 or 4 inches apart. The parsnip is a vegetable of a perfectly hardy character. It may remain in the ground, just where it grows, all winter. The flavor is said to be improved by hard freezing, and no amount of freezing will hurt it.
