have been known to produce it by rolling on stones and other hard
substances. It generally makes its appearance first in the way of a rise
or swelling where the saddle has been allowed to press too hard on the
withers, and especially when the animal has high and lean ones. As the
animal becomes reduced in flesh, the withers, as a matter of course, are
more exposed and appear higher, on account of the muscle wasting from
each side of the back-bone. This, under the saddle, can be remedied to a
great extent, by adding an additional fold to the saddle blanket, or in
making the pad of the saddle high enough to keep it from the withers. In
packing with the pack-saddle this is more difficult, as the weight is
generally a dead, heavy substance, and as the animal steps low or high,
the pack does the same. Much, however, might be done by care in packing,
to prevent injury to the withers and bruising of the back-bone. When the
withers begin to swell and inflammation sets in, or a tumor begins to
form, the whole may be driven away and the fistula scattered or avoided
by frequent or almost constant applications of cold water--the same as
is recommended in poll-evil. But if, in despite of this, the swelling
should continue or become larger, warm fomentations, poultices, and
stimulating embrocations should be applied, in order to bring the
protuberance to its full formation as soon as possible. When full, a
seton should be passed, by a skillful hand, from the top to the bottom
of the tumor, so that all the pus may have free access of escape. The
incision should be kept free until all the matter has escaped and the
wound shows signs of healing. The after treatment must be similar to
that recommended in the case of poll-evil. The above treatment, if
properly administered, will in nearly all cases of _fistula_ effect a
cure.
COLLAR-GALLS.
Sore necks, saddle-galls, and stilfasts, are a species of injury and
sore, which are in many cases very difficult of cure, especially
saddle-galls on mules that have to be ridden every day. One of the best
remedies for saddle gall is to heighten the saddle up as much as
possible, and bathe the back with cold water as often as an opportunity
affords. In many cases this will drive the fever away and scatter the
trouble that is about to take place. This, however, does not always
scatter, for the trouble will often continue, a root forming in the
center of what we call the saddle-gall. The edges of this
