Of the above, 4 are &quot; Red&quot; Clovers; 3 are &quot;White;&quot; 3 arc &quot;Yellow;&quot; 

 and the rest varying, (6.) (//,) and (/,) are in common use with us 

 the latter chiefly in the Western States where it is indigenous. &quot;We 

 Lave distinguished between the &quot;Dutch&quot; and &quot;American&quot; White 

 Clovers, which Botanists do not usually do, but having grown them 

 side by side, we find them essentially different in habit; the first (c,) is a 

 tall, strong growing plant, well adapted for meadows, standing frequent 

 ly, when supported, 18 inches high; while the latter (&amp;lt;f,) is short, ad 

 hering to the ground, and wholly unfit for meadows. If one is only a 

 variety of the other, which appears probable, they are, economically, 

 very distinct. The Dutch or English White Clover would be a valu 

 able addition to our plants of this family. Attempts have been lately 

 made to introduce into America the Alsyke Clover, (&amp;lt;?,) and the seed 

 has been distributed by the Patent Office. It is a native of the South 

 of Europe, but has long been cultivated in Sweden and Germany, where 

 it is very highly esteemed, and latterly in Great Britain. It is de 

 scribed as peculiarly luxuriant. The root is fibrous, and the heads 

 globular. The stems are recumbent, but they do not root in the soil ; 

 &quot;in short it may be described as a giant white clover, with flesh colored 

 flowers.&quot; It yields two mowings annually. It will grow luxuriantly 

 on poor, bare, obdurate clays as -well as on light sands. It ripens its 

 seed much earlier, and continues in vigor much longer than the Red 

 Clovers. When once rooted it will remain for a great many years in 

 full vigor, and produce annually a great quantity of herbage of excel 

 lent quality. A heavier crop of wheat is invariably produced after this 

 than after other clover. The quantity of seed requisite is from 10 to 15 

 pounds per acre, while it will yield over two cwt. on the same area. It 

 does not suffer from the severest frosts ; it will flourish on barren land 

 where few grasses will grow at all ; and with it the soil never becomes 

 &quot; clover sick.&quot; (Dr. Lindley.) Such is its European reputation, and 

 it is certainly worth trying extensively in this country. The seed in 

 London is worth two shillings sterling 50 cents per pound ; and at 

 that price might become with us an article of export.
