The grasses proper grow upon our meadows, pastures, fields and in the woods and are only used as food for cattle.
HOW THE BOTANIST DESCRIBES CEREALS AND GRASSES
The roots of most kinds of grasses are persistent; the stems are hollow and knotty, and the leaves consist of sheaths and discs. Their flowers are arranged either in spikes or panicles, and are essentially the same in form as those of the herbs. In the interior there is an ovary, from which project two pistils with feathery styles. Close to the ovary are three stamens, with very long filaments and large anthers. These internal organs are generally surrounded by two tender bracts called the _paleæ_, and two harder outer bracts forming the _glumes_. In the grasses also self-fertilization does not take place, the wind here taking the place of the insects. Consequently the anthers are suspended from long filaments, and contain a quantity of pollen. As the grasses do not need to attract insects, their flowers are small with little color, and have no scent; nor do they secrete honey. The fruit is enclosed in a husk.
=Alfalfa= (_Medicago sativa_) is a cultivated hay and pasture plant, yielding per annum, without reseeding, three to six or more cuttings of hay, averaging a ton each and often much more, for an indefinite period. It is the richest forage plant known, and while old in history is comparatively new to the agriculture of North America.
Alfalfa thrives on all soils except those too wet or having too much acidity. The former calls for drainage and the latter demands lime. Besides its abundance of rich forage, the leaves of which approximate the value of wheat bran in animal rations, it is highly prized as a soil improver, as it restores and enriches the land in which it grows, and improves extraordinarily the physical character of the soil. Its roots reaching to great depths, make it drought-resistant; they also gather much nitrogen from the air, and it yields assuredly whether the season be wet or dry. It has been demonstrated the greatest fertilizing and soil renovating plant known to agriculture.
For hay it is cut whenever the first blossoms appear or when sprouts for a new growth from the root crowns are discovered, which in some regions is every month in the year. It is relished by all live stock, and is particularly valuable in dairy husbandry, affording at lowest cost important ingredients of the well balanced feeding ration. As pasturage it is excellent for hogs and horses, but ruminants, such as cattle and sheep are not safely grazed upon it, owing to its liability to cause bloat, which if not promptly treated may bring speedy death.
