There are some horses that will not fatten, though you feed them with
the greatest care; and, at the same time, they are perfectly healthy in
other respects. Give to such a horse a pint of pretty strong decoction
of the root of poke-weed. It generally causes him to sweat copiously,
and it often happens, that one dose is sufficient to effect a radical
cure; but, it may be necessary to repeat the dose two or three times:
after which, treat him as you would a horse taken out of the prairie to
be fattened according to the method laid down in this work.
