It is important that American farmers learn to attach much greater importance to the culture of roots. The potato is the best of all roots for feeding; but, as the yield has become so light in most localities, and the demand for it for human food has so greatly increased, it will no longer be grown extensively as food for animals. Farmers must, therefore, turn their attention to beets, carrots, and parsnips. Reasonable tillage will produce one thousand bushels to the acre of beets and carrots, and two hundred more of parsnips. These roots, raw or cooked, are valuable for all domestic animals. A horse will do better on part oats and part carrots, or beets, than upon clear oats. For milch cows, young stock, and fattening cattle, and for sheep and fowls, they are highly valuable. With the facilities now enjoyed, they may be raised at a cheap rate. Plant scarlet short-top radish-seed in the rows, to shade the vegetating seed and young plants, and to mark the rows, to facilitate clearing and stirring the ground, while the plants are very young, and using the most approved root-cleaners, and the same amount of food can not be grown at the same price in any other crops. SAFFRON. This is a well-known medicinal herb, as easily grown as a bean or sunflower. It is principally used in eruptive diseases, to induce moisture of the skin and keep the eruption out. Sow in any good soil, in rows eighteen inches apart, and keep clean of weeds. When in full bloom, the flowers are gathered and dried. SAGE. This is a hardy garden-herb, easily grown. Its value for medicinal and culinary purposes is well known. It is propagated by seeds, or by dividing the roots. With suitable protection in winter, roots will live for a number of years, bearing seed after the first. _Varieties_ are, the _red_, the _broad-leaved_, the _green_, and the _small-leaved green_. The red is most used for culinary purposes, and the broad-leaved is most medicinal. All the varieties may be used for the same purposes. Any garden-soil, not decidedly wet, is suitable for sage. Raise new plants once in three or four years. Plants may be renovated, by certain culture and care, but it is better to grow new ones. Cut the leaves two or three times in the season, and dry quickly, and put away in paper bags; or, better, pulverize and cork up in glass bottles. This is the best method of preserving all herbs for domestic use. SALSIFY, OR VEGETABLE OYSTER.
