STRINGHALT.
This sometimes occurs in the mule. It is a sudden, nervous, quick jerk of either or both of the hind legs. In the mule it frequently shows but little after being worked an hour or so. It is what I regard as unsoundness, and a mule badly affected with it is generally of but little use. It is often the result of strains, caused by backing, pulling and twisting, and heavy falls. You can detect it in its slightest form by turning the animal short around to the right or to the left. Turn him in the track he stands in, as near as possible, and then back him. If he has it, one of these three ways will develop its symptoms. There are a great many opinions as to the soundness or unsoundness of an animal afflicted with this complaint. If I had now a good animal afflicted with it, the pain caused to my feelings by looking at it would be a serious drawback.
CRAMP.
I have now under my charge several mules that are subject to this complaint. It does not really injure them for service, but it is very disagreeable to those having them in charge. It frequently requires from half an hour to two hours to get them rubbed so as the blood gets to its proper circulation, and to get them to walk without dragging their legs.
In cases where they are attacked violently, they will appear to lose all use of their legs. I have known cases when a sudden stroke with a light piece of board, so as to cause a surprise, would drive it away. In other cases sudden application of the whip would have the same effect.
SPAVIN.
It is generally believed that the mule does not inherit this disease.
But this is not altogether true. Small, compact mules, bred after the jack, are indeed not subject to it. On the contrary, large mules, bred from large, coa.r.s.e mares, are very frequently afflicted with it. The author has under his charge at the present time quite a number of those kind of mules, in which this disease is visible. At times, when worked hard, they are sore and lame. The only thing to be recommended in this case is careful treatment, and as much rest at intervals as it is possible to give them. Hand rubbing and application of stimulant liniments, or tincture of arnica, is about all that can be done. The old method of firing and blistering only puts the animal to torture and the owner to expense. A cure can never be effected through it, and therefore should never be tried.
RINGBONE.
These appear on the same kind of large, bony mules as referred to in cases of spavin, and are incurable. They can, however, be relieved by the same process as recommended in spavin. Relief can also be afforded by letting the heels of the affected feet grow down to considerable length, or shoeing with a high-heeled shoe, and thus taking the weight or strain off the injured parts. The only way to make the best use or an animal afflicted with this disease, is to abandon experiments to effect a cure, as they will only be attended with expense and disappointment.
MANGE.
Mules are subject to this disease when kept in large numbers, as in the army. This is peculiarly a cuticle disease, like the itch in the human system, and yields to the same course of treatment. A mixture of sulphur and hog"s lard, one pint of the latter to two of the former. Rub the animal all over, then cover with a blanket. After standing two days, wash him clean with soft-soap and water. After this process has been gone through, keep the animal blanketed for a few days, as he will be liable to take cold. Feed with bran mashes, plenty of common salt, and water. This will relieve the bowels all that is necessary, and can scarcely fail of effecting a cure. Another method, but not so certain in its effect, is to make a decoction of tobacco, say about one pound of the stems to two gallons of water, boiled until the strength is extracted from the weed, and when cool enough, bathe the mule well with it from head to foot, let him dry off, and do not curry him for a day or two. Then curry him well, and if the itching appear again, repeat the bathing two or three times, and it will produce a cure. The same treatment will apply in case of lice, which frequently occurs where mules are kept in large numbers. Mercury should never be used in any form, internally or externally, on an animal so much exposed as the mule.
GREASE-HEEL.
Clean the parts well with castile-soap and warm water. As soon as you have discovered the disease, stop wetting the legs, as that only aggravates it, and use ointment made from the following substances: Powdered charcoal, two ounces; lard or tallow, four ounces; sulphur, two ounces. Mix them well together, then rub the ointment in well with your hand on the affected parts. If the above is not at hand, get gunpowder, some lard or tallow, in equal parts, and apply in the same manner. If the animal be poor, and his system need toning up, give him plenty of nourishing food, with bran mash mixed plentifully with the grain. Add a teaspoonful of salt two or three times a day, as it will aid in keeping the bowels open. If the stable bottoms, or floors, or yards are filthy, see that they are properly cleaned, as filthiness is one of the causes of this disease. The same treatment will apply to scratches, as they are the same disease in a different form.
To avoid scratches and grease-heel during the winter, or indeed at any other season, the hair on the mule"s heels should never be cut. Nor should the mud, in winter season, be washed off, but allowed to dry on the animal"s legs, and then rubbed off with hay or straw. This washing, and cutting the hair off the legs, leave them without any protection, and is, in many cases, the cause of grease-heel and scratches.
SHOES, SHOEING, AND THE FOOT.
The foot, its diseases, and how to shoe it properly, is a subject much discussed among hors.e.m.e.n. Nearly every farrier and blacksmith has a way of his own for curing diseased feet, and shoeing. No matter how absurd it may be, he will insist that it has merits superior to all others, and it would be next to impossible to convince him of his error. Skillful veterinarians now understand perfectly all the diseases peculiar to the foot, and the means of effecting a cure. They understand, also, what sort of shoe is needed for the feet of different animals. Latterly number of shoes have been invented and patented, all professing to be exactly what is wanted to relieve and cure diseased feet of all kinds.
One man has a shoe he calls "_concave_," and says it will cure contraction, corns, thrush, quarter-crack, toe-crack, &c., &c. But when you come to examine it closely, you will find it nothing more than a nicely dressed piece of iron, made almost in the shape of a half moon.
After a fair trial, however, it will be found of no more virtue in curing diseases or relieving the animal than the ordinary shoe used by a country smithy. Another inventive genius springs up and a.s.serts that he has discovered a shoe that will cure all sorts of diseased feet; and brings at least a bushel basket full of letters from persons he declares to be interested in the horse, confirming what he has said of the virtues of his shoe. But a short trial of this wonderful shoe only goes to show how little these persons understand the whole subject, and how easy a matter it is to procure letters recommending what they have invented.
Another has a "specific method" for shoeing, which is to cut away the toe right in the center of the foot, cut away the bars on the inside of the foot, cut and clean away all around on the inside of the hoof, then to let the animal stand on a board floor, so that his feet would be in the position a saucer would represent with one piece broken out at the front and two at the back. This I consider the most inhuman method in the art of shoeing. Turn this saucer upside down and see how little pressure it would bear, and you will have some idea of the cruelty of applying this "specific method." Sometimes bar-shoes and other contrivances are used, to keep the inside of the foot from coming down.
But why do this? Why not get at once a shoe adapted to the spreading of the foot. Tyrell"s shoe for this purpose is the best I have yet seen. We have used it in the Government service for two years, and experience has taught me that it has advantages that ought not to be overlooked. But even this shoe may be used to disadvantage by ignorant hands. Indeed, in the hands of a blacksmith who prefers "his own way," some kinds of feet may be just as badly injured by it as others are benefited. The United States Army affords the largest field for gaining practical knowledge concerning the diseases, especially of the feet, with which horses and mules are afflicted. During the late war, when so little care was given to animals in the field, when they were injured in every conceivable manner, and by all sorts of accidents, the veterinary found a field for study such as has never been opened before.
Experience has taught me, that common sense is one of the most essential things in the treatment of a horse"s foot. You must remember that horses" feet differ as well as men"s, and require different treatment, especially in shoeing. You must shoe the foot according to its peculiarity and demands, not according to any specific "system of shoe."
Give the ground surface a level bearing, let the frog come to the ground, and the weight of the mule rest on the frog as much as any other part of the foot. If it project beyond the shoe, so much the better.
That is what it was made for, and to catch the weight on an elastic principle. Never, under any circ.u.mstances, cut it away. Put two nails in the shoe on each side, and both forward of the quarters, and one in the toe, directly in front of the foot. Let those on the sides be an inch apart, then you will be sure not to cut and tear the foot. Let the nails and nail-holes be small, for they will then aid in saving the foot. It will still further aid in saving it by letting the nails run well up into the hoof, for that keeps the shoe steadier on the foot. The hoof is just as thick to within an inch of the top, and is generally sounder, and of a better substance, than it is at the bottom. Keep the first reason for shoeing apparent in your mind always--that you only shoe your mule because his feet will not stand the roads without it. And whenever you can, shoe him with a shoe exactly the shape of his foot. Some blacksmiths will insist on a shoe, and then cutting and shaping the foot to it. The first or central surface of the hoof, made hard by the animal"s own peculiar way of traveling, indicates the manner in which he should be shod. All the art in the world cannot improve this, for it is the model prepared by nature. Let the shoes be as light as possible, and without calks if it can be afforded, as the mule always travels unsteady on them. The Goodenough shoe is far superior to the old calked shoe, and will answer every purpose where holding is necessary. It is also good in mountainous countries, and there is no danger of the animal calking himself with it. I have carefully observed the different effect of shoes, while with troops on the march. I accompanied the Seventh Infantry, in 1858, in its march to Cedar Valley, in Utah, a distance of fourteen hundred miles, and noticed that scarcely a man who wore regulation shoes had a blister on his feet, while the civilians, who did not, were continually falling out, and dropping to the rear, from the effects of narrow and improper shoes and boots. The same is the case with the animal. The foot must have something flat and broad to bear on.
The first care of those having charge of mules, should be to see that their feet are kept in as near a natural state as possible. Then, if all the laws of nature be observed, and strictly obeyed, the animal"s feet will last as long, and be as sound in his domestic state as he would be in a state of nature.
The most ordinary observer will soon find that the outer portion or covering of the mule"s foot possesses very little animal life, and has no sensibility, like the hair or covering of the body. Indeed, the foot of the horse and mule is a dense block of horn, and must therefore be influenced and governed by certain chemical laws, which control the elements that come in contact with it. Hence it was that the feet of these animals was made to bear on the hard ground, and to be wet naturally every time the horse drank. Drought and heat will contract and make hard and brittle the substance of which the feet is composed; while on the other hand cooling and moisture will expand it, and render it pliable and soft. Nature has provided everything necessary to preserve and protect this foot, while the animal is in a natural state; but when brought into domestic use, it requires the good sense of man, whose servant he is, to artificially employ those means which nature has provided, to keep it perfectly healthy.
When, then, the foot is in a healthy state, wet it at least twice a day; and do not be content with merely throwing cold water on the outside, for the foot takes in very little if any moisture through the wall. In short, it absorbs moisture most through the frog and sole, particularly in the region where the sole joins the wall. This, if covered by a tight shoe, closes the medium, and prevents the proper supply. Horses that are shod should be allowed to stand in moist places as much as possible. Use clay or loam floors, especially if the horse has to stand much of his time. Stone or brick is the next best, as the foot of the animal will absorb moisture from either of these. Dry pine planks are the very worst, because they attract moisture from the horse"s foot. Where animals have to stand idle much of the time, keep their feet well stuffed with cow manure at night. That is the best and cheapest preservative of the feet that you can use.
ADVICE TO BLACKSMITHS.
Let me enjoin you, for humanity"s sake, that when you first undertake to shoe a young animal, you will not forget the value of kind treatment.
Keep its head turned away from the glaring fire, the clinking anvil, &c., &c. Let the man whom he has been accustomed to, the groom or owner, stand at his head, and talk to him kindly. When you approach him for the first time, let it be without those implements you are to use in his shoeing. Speak to him gently, then take up his foot. If he refuse to let you do this, let the person having him in charge do it. A young animal will allow this with a person he is accustomed to, when he will repel a stranger. By treating him kindly you can make him understand what is wanted; by abusing him you will only frighten him into obstinacy. When you have got the animal under perfect subjection, examine the foot carefully, and you will find the heels, at the back part of the frog, entirely free from that member, which is soft and spongy. When the foot is down, resting on the ground, grasp the heels in your strong hand, press them inwards towards the frog, and you will immediately find that they will yield. You will then see that what yields so easily to the mere pressure of the hand will expand and spread out when the weight of the body is thrown on it. This should give you an idea of what you have to do in shoeing that foot, and your practical knowledge should stand you well in an argument with any of those "learned professors," who declare the foot of the mule does not expand or contract. In truth it is one of its necessary conditions. After being a long time badly shod, nearly or all of this necessary principle of the foot will be lost. You should therefore study to preserve it. And here let me give you what little aid experience has enabled me to do. You will observe the ground surface of the foot, no matter how high the arch may be, to be at least half an inch wide, and sometimes more than an inch, with the heels spread out at the outside quarter. Do not cut away this important brace.
It is as necessary to the heel of the animal, to guard him against lateral motion, on which the whole of the above structure depends, as the toes are to the human being. Curve the outside of the shoe nearly to fit the foot, and you will find the inside heel a little straighter, especially if the animal be narrow-breasted, and the feet stand close together. Nature has provided this safeguard to prevent its striking the opposite leg. After the shoe is prepared to fit the foot, as I have before described, rasp the bottom level--it will be found nearly so. Do not put a knife to the sole or the frog. The sole of the foot, remember, is its life, and the frog its defender. In punching the shoe, two nail-holes on a side, on a foot like this, are sufficient to hold on a shoe. Three may be used, if set in their proper places, without injury to the foot. Practice will teach you that any more nailing than this is unnecessary. I have used two nails on a side on an animal with not the best of a foot, and very high action, and he has worn them entirely out without throwing either of them off. Previous to punching the shoe, observe the grain of the foot. It will be seen that the fibres of the hoof run from the top of the foot, or coronary border, towards the toe, in most feet, at an angle of about forty-five degrees. It will be plain, then, that if the nails are driven with the grain of the horn, they will drive much easier, and hold better, and be less liable to cut and crack the fibers.
Another benefit can be derived from this process of nailing. When the foot comes to the ground, the nails act as a brace to keep the foot from slipping forward off the shoe. This renders that very ingenious foot destroyer, the toe-clip, unnecessary. Then, in punching the shoe, hold the top of the pritch.e.l.l toward the heel of the shoe, so as to get the hole in the shoe on an angle with the grain of the hoof. Punch the holes large enough, so that the nails will not bind in the shoe, nor require unnecessary hammering or bruising of the foot to get them up to their proper place. Prepare the nails well, point them thin and narrow; and, as I have said before, use as small a nail as possible.
When you proceed to nail on the shoe, take a slight hold at the bottom, so as to be sure that the nail starts in the wall of the foot instead of the sole. Let it come out as high up as possible. You need not be afraid of p.r.i.c.king with nails set in this way, as the wall of the foot is as thick, until you get within half an inch of the top, as it is where you set the nail. Nails driven in this way injure the feet less, hold on longer, and are stronger than when driven in any other way. If you have any doubt of this, test it in this manner: when you take off an old shoe to set a new one, and cut the clinches (which should be done in all cases), you will find the old nail and the clinches not started up; and in drawing the nail out you will also find the foot not slipped or cracked; and that the horn binds the nail until it is entirely drawn out. Indeed, I have known the hole to almost close as the nail left it.
Set the two front nails well towards the toe, so as not to be more than two inches apart when measured across the bottom of the foot. Let the next two divide the distance from that to the heel, so as to leave from two to two and a half inches free of nails, as the form of the foot may allow. Lastly, before nailing on the shoe, and while it is cold on the anvil, strike the surface that comes next to the foot on the outside, a few blows with the hammer, right across the heels, and see also that the outside of the heels is a shade lowest, so that the animal in throwing his weight upon them will spread out, and not pinch in his feet.
