The first thing to be done is to liberate the head by cutting the rope, or the halter, if the horse be bound by a chain. Place him in a favorable position, and urge him to rise. After a horse has lain long in constraint, it is often difficult to get him up. Sometimes he is perfectly unable to rise. His limbs are benumbed; they are, I suppose, in much the same state as our own when we say they are asleep. The horse must have some assistance. Let one stout fellow support the head, another the shoulder, and place two at the tail, by seizing which they may lift the hind-quarters. Draw the fore-legs out, but not too much; the horse rises head first. See that all hands be ready to give their aid at the moment the horse makes an effort to rise, and to this he may be urged by the lash. When on his legs steady him for a minute or two'; encourage him to urinate.
Let his legs and the side upon which he lay, be well rubbed If able to walk a few paces, it will help to circulate the blood. If he can not walk at first, try him again after half an hour Examine him all over, lest he have received any injury re quiring immediate treatment. He will not be fit to work on that day, and perhaps not the next.
Sometimes the horse can not be got upon his feet.; he can not even make an effort to rise. Turn him over to his other side, and let that which was undermost be well rubbed with wisp or brush; manipulate the skin - that is, pinch it, and raise it from the flesh, in order to restore the circulation of blood through it. With the same intention let. the legs be rubbed, pulled, and the joints alternately bent and straightened. Give the horse a good bed, and as much room as possible. If the travis can be removed, take it away. If the horse have no sign of fever, give him half a pint of sherry in cold water, or a cordial-ball; let him also have some water, and if he will eat oats, give them. By these means the horse may recover his strength and the use of his limbs sufficiently to rise with assistance. A trial should be made every half hour; when not successful, there is nothing for it but the block and tackle, which may be fixed to some beam or support across the stall. Pass a couple of strong ropes round the chest, and attach them to the pulley; pad them with straw where they are like ly to cut the skin. If the horse can not stand when thus raised, support him a little in the ropes; place his legs fair below him, and let his weight upon them very gradually.
If he can not use them at all, let him down again, and make other efforts to restore his activity; give more wine, rubbing, food, and water. Turn him often, and raise him again in an hour. - In a few cases the horse never recovers the use of his legs. He dies, or is destroyed. This happens from injury of the back, the neck, and the head. But I have seen the horse completely paralytic, when there was no appearance of injury in these parts.
The treatment here recommended for stall-casting, is equally applicable to horses that have been cast in the field, in a ditch, or any situation where they have lain long in a position of constraint. The wine-cordial some people will object to, but it is an excellent remedy against exhaustion.
