The CARROT is somewhat extensively fed, and is a valuable root for milch cows. This, like the potato, has been cultivated and improved from a wild plant. Carrots require a deep, warm, mellow soil, thoroughly cultivated, but clean, and free from weed-seed. The difference between a very good profit and a loss on the crop depends much upon the use of land and manures perfectly free from foul seeds of any kind. Ashes, guano, seaweed, ground bones, and other similar substances, or thoroughly-rotted and fermented compost, will answer the purpose. After plowing deep, and harrowing carefully, the seed should be planted with a seed-sower, in drills about eighteen inches apart, at the rate of four pounds to the acre, about the middle of May. The difference between sowing on the fifteenth of May and on the tenth of June in New England is said to be nearly one-third in the crop on an average of years. In weeding, a little wheel hoe is invaluable, as with it a large part of the labor of cultivation is saved. A skillful hand can run this hoe within a half an inch of the young plants without injury, and go over a large space in the course of a day, if the land was properly prepared in the first place. The American farmer should always plan to economize labor, which is the great item of expense upon a farm. By this is not meant that he should strive to shirk or avoid work, but that he should make the least amount of work accomplish the greatest and most profitable results. Labor-saving machinery on the farm is applied, not to reduce the number of hours of labor, or to make the owner a man of leisure--who is, generally, the unhappiest man in the world--but to enable him to accomplish the greatest results in the same time that he would be compelled to obtain smaller ones. Carrots will continue to grow and increase in size late into the fall. When ready to dig, plow around as near to the outside rows as possible, turning away the furrow from the row. Then take out the carrots, pulling off the tops, and throw the carrots and tops into separate heaps on the plowed furrows. In this way a man and two boys can harvest and put into the cellar upwards of a hundred bushels a day. The TURNIP, and the Swedish turnip, or ruta baga, are also largely cultivated as a field crop to feed to stock; and for this purpose almost numberless varieties are used, furnishing a great amount of succulent and nutritious food, late into winter, and, if well-kept, late into spring. The chief objection to the turnip is, that it taints the milk. This may be remedied--to a considerable extent, if not wholly--by the use of salt, or salt hay, and by feeding at the time of milking, or immediately after, or by steaming before feeding, or putting a small quantity of the solution of nitre into the pail, and milking upon it.
