THE TALL OAT GRASS is the Ray grass of France. It furnishes a luxuriant supply of foliage, is valuable either for hay or for pasture, and has been especially recommended for soiling purposes, on account of its early and luxuriant growth. It is often found on the borders of fields and hedges, woods and pastures, and is sometimes very plenty in mowing-lands. After having been mown it shoots up a very thick aftermath, and, on this account, partly, is regarded of nearly equal excellence with the common foxtail. It grows spontaneously on deep, sandy soils, when once naturalized. It has been cultivated to a considerable extent in this country, and is esteemed by those who know it mainly for its early, rapid, and late growth, making it very well calculated as a permanent pasture grass. It will succeed on tenacious clover soil. The SWEET-SCENTED VERNAL GRASS is one of the earliest in spring and one of the latest in autumn; and this habit of growth is one of its chief excellencies, as it is neither a nutritious grass, nor very palatable to stock of any kind, nor does it yield a very good crop. It is very common in New England and all over the Middle States, coming into old worn-out fields and moist pastures spontaneously, and along every roadside. It derives its name from its sweetness of odor when partially wilted or crushed in the hand, and it is this chiefly which gives the delicious fragrance to all new-mown bay. It is almost the only grass that possesses a strongly-marked aromatic odor, which is imparted to other grasses with which it is cured. Its seed weighs eight pounds to the bushel. In mixtures for permanent pastures it may be of some value. HUNGARIAN GRASS, or millet, is an annual forage plant, introduced into France in 1815, and more recently into this country. It germinates readily, and withstands the drought remarkably, remaining green when other grasses are parched and dried up. It has numerous succulent leaves which furnish an abundance of sweet fodder, greatly relished by stock of all kinds. It attains its greatest luxuriance on soils of medium consistency and richness, but does very well on light and dry plains. RED CLOVER is an artificial grass of the leguminous family, and one of the most valuable cultivated plants for feeding to dairy cows. It flourishes best on tenacious soils and stiff loams. Its growth is rapid, and a few months after sowing are sufficient to supply an abundant sweet and nutritious food. In the climate of New England, clover should be sown in the spring of the year, while most of the natural grasses do far better when sown in the fall. It is often sown with perfect success on the late snows of March or April, and soon finds its way down into the soil and takes a vigorous hold with its root. It is valuable not only as a forage plant, but as shading the ground, and thereby increasing its fertility.
