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
