Physic is necessary in this case; a gentle blood-letting, even, may be required, followed by a few doses of febrifuge medicine; but the treatment should be carried no further than is necessary to reduce the pulse to fifty-five degrees. The leg should be wrapped in a stout linen bandage; day and night the part should be saturated with the coldest possible water until the primary symptoms have abated. Cut grass should be the food while any fever rages, but no longer, for the wish is not to destroy the powers of reparation by weakening the body. The cold water should be continued till recovery appears confirmed; but it will be many months before the horse, thus disabled, will again be fit for full or energetic work. Commonly, however, this accident takes place in the hunting-field; and sportsmen, silly as may be their amusements, are no niggards. If they occasionally injure a horse, they will spare no expense that can aid its restoration; and a summer's rest may not be thrown away upon the favorite which has met with such a mishap. However, the mark will remain for life--an obvious swelling will, during existence, denote the place where clap occurred to the back sinews. SPRAIN OF THE BACK SINEWS. =Sprain of the back sinews= of the hind legs is very general among animals which have to perform slow work upon hilly roads. People in the carrier trade can afford to bestow small attention upon the lameness which does not incapacitate. Every journey, however, aggravates the disease. The horse works on till his owner is told by the blacksmith the animal's legs are contracting, and higher calkins are given as a cure. [Illustration: HIGH CALKINS. The earliest attention commonly paid to sprain of the back sinews of the hind leg. ] At length, however, calkins become of no use. The work continues, and the disease progresses. The position of the foot is now so altered, that the smith discovers his office is unable to render the animal useful. Perhaps these circumstances would little affect the owner, but the horse evidently loses power. At first it is longer on the road. The passengers grumble at the delay, (for country carriers reap no little profit by carrying passengers;) and the driver, flog as he may, can oblige the horse to move no faster. Excessive beating is apt to provoke pity; and every word of pity which is lavished on the evidently eager animal is distasteful to the carrier, who vents his anger upon the wretched cause of all "this rumpus."
