There is both negligence, and mistake, in the way of wintering pigs. I
am not talking to those whose manner of keeping stock is, to let stock
take care of themselves; but to farmers who _mean to be careful_. Hogs
should be _sorted_. The little ones will, otherwise, be cheated at the
trough, and overlaid and smothered in the sleeping-heap. There should
not be too many in one inclosure; especially young pigs should not
sleep in crowds; for, although they sleep warmer, they will suffer on
that very account. Lying in piles, they get sweaty; the skin is much
more sensitive to the cold, and coming out in the morning reaking and
smoking, the keen air pierces them. In this way, young pigs die off
through the winter by being too warm at night. If you have the
land-shark and alligator breed, however, you should crowd these
together, for the more they die off the better for the farmer.
