The introduction of clover among the cultivated plants of the farm has done more, perhaps, for modern agriculture than that of any other single plant. It is now considered indispensable in all good dairy districts. WHITE CLOVER, often called Honeysuckle, is also widely diffused over this country, to which it is undoubtedly indigenous. As a mixture in all pasture grasses it holds a very high rank, as it is exceedingly sweet and nutritious, and relished by all kinds of stock. It grows most luxuriantly in moist grounds and moist seasons, but easily accommodates itself to a great variety of circumstances. With respect to the mixtures of grass-seeds most profitable for the dairy farmer, no universal rule can be given, as they depend very much upon the nature of the soil and the locality. The most important point to be observed, and the one as to which, probably, the greatest deficiency exists, is to use a large number of species, with smaller quantities of each than those most commonly used. This is Nature's rule; for, in examining the turf of a rich old pasture, a large number of different species will be found growing together, while, if the turf of a field sown without two or three species is examined, a far less number of plants is found to the square foot, even after the sod is fairly set. In the opinion of the most competent judges, no improvement in grass culture is more important than this. As an instance of what he would consider an improvement on the ordinary mixtures for _permanent pastures_, Mr. Flint, in his "Milch Cows and Dairy Farming," suggests the following as likely to give satisfactory results, dependent, of course, to a considerable extent, on the nature and preparation of the soil: Meadow Foxtail, flowering in May and June, 2 pounds Orchard Grass, " " " " 6 " Sweet-scented Vernal, " " April and May, 1 " Meadow Fescue, " " May and June, 2 " Redtop, " " June and July, 2 " June Grass, " " May and June, 4 " Italian Rye Grass, " " June, 4 " Perennial do., " " " " 6 " Timothy, " " June and July, 3 " Rough-stalked Meadow Grass, " " 2 " Perennial Clover, flowering in June, 3 " White Clover, " " May to September 5-40 " For mowing-lands the mixture would, of course, be somewhat changed. The meadow foxtail and sweet-scented vernal would be left out entirely, and some six or eight pounds added to the Timothy and red clover. The proper time to lay down lands to grass in the latitude of New England is August or September, and no grain crop should be sown with the seed.
