THE GRASSES. -- SHALL WE SOW A GREATER VARIETY? The value of grasses for pasture and hay for our stock is hardly second in importance to that of their grain for human food. In new countries of the United States, about the only grasses cultivated are timothy, Phleum pratense,) frequently sown with clover on dry land; and red top (Agrostis vulgaris) on moist low land or marshes. Besides these, after a few years, several others creep in and increase the variety and improve quality of old meadows and pastures. Orange County, in the State of New York has become famous throughout our land for the excellent quality of her butter and cheese. Great care is taken in their manufacture, but the selection of grasses for pasture is by no means overlooked. In the transactions of the Agricultural Society for 1865, X. A. Willard reports that he made extensive inquiries of the best dairymen as to the kinds of grasses employed. Some affirmed that it was impossible to obtain the best flavored butter, or so large a result from recently re seeded grounds of clover and timothy. The grasses there found in old pastures, are June or Kentucky blue grass (Poa pratensis), the fowl meadow grass (Poa serotina), meadow fescue, (Festuca pratensis) red top, (Agrostis aulgaris,) the wire grass, (Poa compressa,) and the sweet-scented vernal and vanilla grass. Timothy, orchard grass, red clover and other forage plants are also grown in new pastures and meadows. Here are mentioned six species for pastures, and a fewer number for meadows. An elaborate article on the grasses of Pennsylvania, by J. M. McMinn, appeared in the New York Tribune two years ago. There, in the fine grazing fields, where considerable attention had been given to the subject, are found about six leading grasses unless a determined destruction of all but one or two had been practiced. In the pastures are found green grass, (Poa pratensis)-observe the common name is different from the one used in New York-timothy, red top, false red top (Tricuspis seslerioides) blue grass (Poa compressa) fesaque grass, (Festuca pratensis). In the meadows are found rough meadow grass (Poa trivialis), dwarf meadow grass (Poa annua), feather grass (Holcus lanatus), fall meadow grass (Arrhenatherum avenaceum), sweet-cented meadow grass (Anthoxanthum adoratum), and manna grass (Poa aquatica). Others, which it might be tedious to mention, are found in their orchards and shaded lawns, others on dry hills, others still on lake meadows, and yet others mostly different from any of the rest on marshes of the sea shore. In various parts of the Southern States are found species differing from any yet mentioned. If some of these best suited to a locality are wanting, others will take their places, though they may not be exactly adapted to the soil and climate. Let us take a glance at our English brethren across the water. Although some of us are fond of saying that they do not equal the people of the United States in pianos, sewing machines, reapers, Yankee notions, and some other modern inventions, yet they have for a great many years been celebrated for their fine pastures and meadows. They have tried & great many valuable experiments in this direction, while in our younger country, with its vastly greater variety of soil and climate, very little has been done. In a prize essay by Prof. James Buchman, of the Royal Agricultural College, 1854, he divides the grasses into five groups. 1st. Jungle or bush grasses; he mentions nine of these. 2d. Aquatic or water grasses; he mentions eight of little value. 3d. Marine or sea side grasses; he gives names of five. 4th. Meadow or pasture grasses; he mentions twenty or more, all of which are cultivated and prove valuable. This does not include a large number often called grasses, as red clover. Though selections are made for certain soils, it does not stand to reason that one or two grasses are best for all localities, any more than one medicine is good for all diseases. The Englishmen selects some kinds of grass for their soil or upland pastures, others for stiff clays, others for rich deep loams, others for meadows which are subject to periodic floods along the banks of rivers, and still others for irrigated meadows, in which the water can be easily controlled. Our English author mentions a fifth class, agrarian grasses, twelve species, though part of them are often great pests on account of their long underground roots or early seeding. Here is a contrast to the English account just referred to: S. D. Harris, in a prize essay for which he was awarded fifty dollars by the State Agricultural Society of Ohio, 1858, page 252, says: "Of the grasses that may be called indigmous and at the same time having the virtues of what are called tame grasses, there are but three kinds deserving of culture in Ohio. These are the Poa pratentis, Poa compressa and Trifolium repens, and all worthy of cultivation from any source on arable land are Timothy, red top (Ayrostis vulgaris,) orchard grass, red clover, and for scarcity of crop occasionally German millet and common millet. We should suffer no loss were all the rest stricken from our fields at once." Here for most uses then, he names three grasses- and one of them a clover -- and two more in extreme cases. Six species in all. Cattle, sheep and horses, would, no doubt, thrive on plenty of these, but they could hardly from experience say "variety is the spice of life.' Pigs will fatten on corn and water alone, but' they will be healthier with a greater variety of food and will grow more rapidly. In England and Scotland the best farmers sow as many as twenty-one kinds of grass seed mixed together. In some cases fewer kinds are sown, but we cannot read of a mixture recommended which contains less than eleven or more kinds. Who ever heard of the like on an American farm? Who dare say that one or two or three kinds are better than more for all cases, all climates and seasons, soils and uses? Are we not deficient in our attention to this important subject ? W. J. B.
