56.  Trifolium procumbens.  Yellow suckling.—­An annual very like the Nonsuch; it is a very useful plant, seeding very freely in pastures and growing readily, by which means it is every year renewed, and affords a fine bite for sheep and cattle.  I have now and then seen the seeds of this in the shops, but it is not common.  There is a gentleman who cultivates this plant very successfully near Horsham, and who, I am informed, states it to be the best kind of Clover for that land.  It grows very commonly amongst the herbage on Horsham Common, so that it is probably its native habitat.  The seeds are the smallest of all the cultivated Clovers, and of course less in weight will be necessary for the land.

57.  Trifolium ochroleucum.  Yellow clover.—­This is not a common plant, but it deserves the attention of the grazier.  I believe it is not in cultivation.  In the garden it stands well, and is a large plant.  The herbage appears to be as good as that of any other kind of Clover, and it might, if introduced, be cultivated by similar means.

58.  Trifolium agrarium.  Hop trefoil.—­This is also a good plant, but not in cultivation; it is eaten by cattle in its wild state, is a perennial, and certainly deserves a trial with such persons who may be inclined to make experiments with these plants.

Buffalo Clover is a kind similar to Trifolium agrarium and Trifolium repens, and appears to me to be a hybrid plant.  This has been sometimes sent to this country from America, and is a larger plant than either.  It has, however, as far as I have grown it, the same property of exhausting the soil as all the other species possess, and is soon found to go off:  it is not in cultivation to any large extent.

59.  Vicia Cracca.  Tufted vetch.—­Persons who have most noticed this plant have imagined it might be introduced into cultivation.  It is hardy, durable, nutritious, and productive; but, like the Yellow Vetchling, the seeds do not readily vegetate; the only way to cultivate it, therefore, would be by planting out the roots; which might be done, as they are easily parted and are to be procured in great plenty in the places where it grows wild.

60.  Vicia sativa.  VETCHES, fetch, or tare.—­A very useful and common plant, of which we have two varieties known to the farmer by the name of Spring and Winter Tares:  they are both annuals.  The spring variety is a more upright growing plant, and much tenderer than the other:  it is usually sown in March and April, and affords in general fine summer fodder.
