The principal operator seats himself on a chair, having within his reach a couple of good knives, a whetstone, the powerful toe-nippers already described, a bucket of water with a couple of linen rags in it, together with such medicines as may be deemed necessary. The assistant catches a sheep and lays it partly on its back and rump, between the legs of the foreman, the head coming up about to his middle. The assistant then kneels on some straw, or seats himself on a low stool at the hinder extremity of the sheep. If the hoofs are long, and especially if they are dry and tough, the assistant presents each foot to the operator who shortens the hoof withthe toe-nippers. If there is any filth between the toes, each man takes his rag from the bucket of water, and draws it between the toes, and rinses it, until the filth is removed. Each then takes a knife, and the process of paring away the horn commences,upon the effectual performance of whichall else depends. A glance at the foot will show whether it is the seat of the diseased action. The least experience cannot fail in properly settling this question. An experienced finger, even, placed upon the back of the pastern close above the heel, will at once detect the local inflammation, in the dark,by its heat.
If the disease is in the first stage—that is, if there are merely erosion and ulceration of the cuticle and flesh in the cleftabovethe walls of the hoof—no paring is necessary. But if ulceration has established itself between the hoof and the fleshy sole,the ulcerated parts, however extensive,must be entirely stripped of their horny covering, no matter what amount of time and care it may require. It is better not to wound the sole so as to cause it to bleed freely, as the running blood will wash off the subsequent application; but no fear of wounding the sole must prevent a full compliance with the rule laid down above. At the worst, the blood will stop flowing after a little while, during which time no application needs to be made to the foot.
If the foot is in the third stage—a mass of rottenness, and filled with maggots—pour, in the first place, a little spirits of turpentine—a bottle of which, with a quill through the cork, should be always ready—on the maggots, and most of them will immediately decamp, and the others can be removed with a probe or small stick. Thenremove every particle of loosehorn, though it should take the entire hoof, as it generally will in such cases. The foot should next be cleansed with a solution of chloride of lime, in the proportion of one pound of chloride to one gallon of water. If this is not at hand, plunging the foot repeatedly in hot water, just short of scalding hot, will answer every purpose. The great object isto clean the foot thoroughly. If there is any considerable “proud flesh,” it should be removed with a pair of scissors, or by the actual cautery—hot iron.
The following are some of the most popular remedies: Take two ounces of blue vitriol and two ounces of verdigris, to a junk-bottle of wine; or spirits of turpentine, tar, and verdigris in equal parts; or three quarts of alcohol, one pint of spirits of turpentine, one pint of strong vinegar, one pound of blue vitriol, one pound of copperas, one and a half pounds of verdigris, one pound of alum, and one pound of saltpetre, pounded fine; mix in a close bottle, shake every day, and let it stand six or eight days before using; also mix two pounds of honey and two quarts of tar, which must be applied after the preceding compound. Or apply diluted aquafortis—nitric acid—with a feather to the ulcerated surface; or diluted oil of vitriol—sulphuric acid—in the same way; or the same of muriatic acid; or dip the foot in tar nearly at the boiling point.
In the first and second stages of the disease, before the ulcers have formed sinuses into the sole, and wholly or partly destroyed its structure, the best application is a saturated solution of blue vitriol—sulphate of copper. In the third stage, when the foot is a festering mass of corruption, after it has been cleansed as already directed, it requires some strongcaustic to remove the unhealthy granulations—the dead muscular structures—and to restore healthy action. Lunar caustic, which is preferable to any other application, is too expensive; chloride of antimony is excellent, but frequently unattainable in the country drug-stores; and muriatic acid, or even nitric or sulphuric acids, may be used instead. The diseased surface is touched with the caustic, applied with a swab, formed by fastening a little tow on the end of a stick, until the objects above pointed out are attained. The foot is then treated with the solution of blue vitriol, and subsequently coated over with tar which has been boiled, and is properly cooled, for the purpose of protecting the raw wound from dirt, flies, etc. Sheep in this stage of the disease should certainly be separated from the main flock, and looked to as often as once in three days. With this degree of attention, their cure will be rapid, and the obliterated structures of the foot will be restored with astonishing rapidity.
The common method of using the solution of blue vitriol is to pour it from a bottle with a quill in the cork, into the foot, when the animal lies on its back between the operators, as already described. In this way a few cents’ worth of vitriol will answer for a large number of sheep. The method is, however, imperfect; since, without extraordinary care, there will almost always be some slight ulcerations not uncovered by the knife, which the solution will not reach, the passages to them being devious, and perhaps nearly or quite closed. The disease will thus be only temporarily suppressed, not cured.
A flock of sheep which were in the second season of the disease, had been but little looked to during the summer, and as cold weather set in, many of them became considerablylame, and some of them quite so. Their feet were thoroughly pared; and into a large washing-tub, in which two sheep could conveniently stand, a saturated solution of blue vitriol and water,as hot as could be endured by the hand even for a moment, was poured. The liquid was about four inches deep on the bottom of the tub, and was kept at that depth by frequent additions of hot solution. As soon as a sheep’s feet were pared, it was placed in the tub, and held there by the neck. A second one was then prepared, and placed beside it; when the third was ready, the first was taken out; and so on. Two sheep were thus constantly in the tub, each remaining some five minutes. The cure was perfect; there was not a lame sheep in the flock during the winter or the next summer. The hot liquid penetrated to every cavity of the foot; and doubtless had a far more decisive effect, even on the uncovered ulcers, than would have been produced by merely wetting them. The expense attending the operation was aboutfour centsper sheep. Three such applications, at intervals of a week, would effectually cure the disease, since every new case would thus be arrested and cured before it would have time to inoculate others. It would, undoubtedly, accomplish this at any time of year, and even during the first and most malignant prevalence of the contagion,provided the paring was sufficiently thorough. The second and third parings would be a mere trifle; and the liquid left at the first and second applications could again be used. Thus sheep could be cured at about twelve cents per head, which is much cheaper, in the long run, than any ordinary temporizing method, where the cost of a few pounds of blue vitriol is counted, but not the time consumed; and the disease is thus kept lingering in the flock for years.
Some Northern farmers drive their sheep over dusty roads as a remedy for this disease; and in cases of ordinary virulence, especially where the disease is chronic, it seems to dry up the ulcers, and keep the malady under. Sheep are also sometimes cured by keeping them on a dry surface, and driving them over a barn-floor daily, which is well covered with quick-lime. It may sometimes, and under peculiar circumstances, be cured by dryness, and repeated washing with soap-suds.
Many farmers select rainy weather as the time for doctoring their sheep. Their feet are then soft, and it is therefore on all accounts good economy, when the feet are to be pared, and each separately treated,providedthey can be kept in sheep-houses, or under shelters of any kind, until the rain is over, and the grass again dry. If immediately let out in wet grass of any length, the vitriol or other application is measurably washed away. This is avoided by many, by dipping the feet in more tar—an admirable plan under such circumstances.
A flock of sheep which have been cured of the hoof-ail, is considered more valuable than one which has never had it. They are far less liable to contract the disease from any casual exposure; and its ravages are far less violent and general among them.
This ailment should not be confounded with a temporary soreness, or inflammation of the hoof, occasioned by the irritation from the long, rough grasses which abound in low situations, which is removed with the cause; or, if it continues, white paint or tar may be applied, after a thorough washing.
This is not common, to any dangerous degree, among sheep; but, if turned upon clover when their stomachs are empty, it will sometimes ensue.
Hoove is a distension of the paunch by gas extricated from the fermentation of its vegetable contents, and evolved more rapidly, or in larger quantities, than can be neutralized by the natural alkaline secretions of the stomach. When the distention is great, the blood is prevented from circulating in the vessels of the rumen, and is determined to the head. The diaphragm is mechanically obstructed from making its ordinary contractions, and respiration, therefore, becomes difficult and imperfect. Death, in such cases, soon supervenes.
Treatment.In ordinary cases, gentle but prolonged driving will effect a cure. When the animal appears swelled almost to bursting, and is disinclined to move, it is better to open the paunch at once. At the most protruberant point of the swelling, on the left side, a little below the hip bone, plunge a trochar or knife, sharp at the point and dull on the edge, into the stomach. The gas will rapidly escape, carrying with it some of the liquid and solid contents of the stomach. If no measures are taken to prevent it, the peristaltic motion, as well as the collapse of the stomach, will soon cause the orifices through the abdomen and paunch not to coincide, and thus portions of the contents of the former will escape into the cavity of the latter.
However perfect the cure of hoove, these substances in the belly will ultimately produce fatal irritation. To prevent this, a canula, or little tube, should be inserted through bothorifices as soon as the puncture is made. Where the case is not imminent, alkalies have sometimes been successfully administered, which combine with the carbonic acid gas, and thus at once reduce its volume. A flexible probang, or in default of it, a rattan, or grape-vine, with a knot on the end, may be gently forced down the gullet, and the gas thus permitted to escape.
The symptoms of this disease, known as turnsick, sturdy, staggers, water in the head, etc., are a dull, moping appearance, the sheep separating from the flock, a wandering and blue appearance of the eye, and sometimes partial or total blindness; the sheep appears unsteady in its walk, will sometimes stop suddenly and fall down, at others gallop across the field, and, after the disease has existed for some time, will almost constantly move round in a circle—there seems, indeed, to be an aberration of the intellect of the animal. These symptoms, though rarely all present in the same subject, are yet sufficiently marked to prevent any mistake as to the nature of the disease.
On examining the brain of sheep thus affected, what appears to be a watery bladder, called a hydatid, is found, which may be either small or of the size of a hen’s egg. This hydatid, one of the class of entozoöns, has been termed by naturalists thehydatis polycephalus cerebralis, or many-headed hydatid of the brain; these heads being irregularly distributed on the surface of the bladder, and on the front part of each head there is a mouth surrounded by minute sharp hooks within a ring of sucking disks. These disks serve as the means of attachment,by forming a vacuum, and bring the mouth in contact with the surface, and thus, by the aid of the hooks, the parasite is nourished. The coats of the hydatid are disposed in several layers, one of which appears to possess a muscular power. These facts are developed by the microscope, which also discloses numerous little bodies adhering to the internal membrane. The fluid in the bladder is usually clear but occasionally turbid, and then it has been found to contain a number of minute worms.
Treatment.This is deemed an almost incurable disorder. Where the hydatid is not imbedded in the brain, its constant pressure, singularly enough, causes a portion of the cranium to be absorbed, and finally the part immediately over the hydatid becomes thin and soft enough to yield under the pressure of the finger.
When such a spot is discovered, the English veterinarians usually dissect back the muscular integuments, remove a portion of the bone, carefully divide the investing membranes of the brain, and then, if possible, remove the hydatid whole; or, failing to do this, remove its fluid contents. The membranes and integuments are then restored to their position, and an adhesive plaster placed over the whole. The French veterinarians usually simply puncture the cranium and the cyst with a trochar, and laying the sheep on its back, allow the fluid to run out through the orifice thus made. A common awl would answer every purpose for such a puncture; and the puncture is the preferable method for the unskilled practitioner. An instance is, indeed, recorded of a cure having been effected, where the animal had been given up, by boring with a gimlet into the soft place on the head, when the waterrushed out, and the sheep immediately followed the others to the pasture.
When, however, the hazard and cruelty attending the operation, under the most favorable circumstances, are considered, as well as the conceded liability of a return of the malady—the growth of new hydatids—it is evident that in this country, it would not be worth while, except in the case of uncommonly valuable sheep, to adopt any other remedy than depriving the miserable animal of life.

After pouring a little oil in the throat, the obstructing substance which occasions the “choking,” can frequently be removed up or down by external manipulation. If not, it may usually be forced down with the flexible probang, described in “Cattle and their Diseases,” or a flexible rod, the head of which is guarded by a knot, or a little bag of flax-seed. The latter having been dipped in hot water for a minute or two, is partly converted into mucilage, which constantly exudes through the cloth, and protects the œsophagus, or gullet, from laceration. But little force must be used, and the whole operation conducted with the utmost care and gentleness; or the œsophagus will be so far lacerated as to produce death, although the obstruction is removed.
Ophthalmia, or inflammation of the eyes, is not uncommon in this country; but it is little noticed, as, in most cases, it disappears in a few days, or, at worst, is only followed by cataract, which, being usually confined to one eye, does not appreciably effect the value of the animal, and therefore has no influence on its market price.
Treatment.Some recommend blowing pulverized red chalk in the inflamed eye; others squirt into it tobacco juice. As a matter of humanity, blood may be drawn from under the eye, and the eye bathed in tepid water, and occasionally with a weak solution of the sulphate of zinc combined with tincture of opium. These latter applications diminish the pain, and hasten the cure.
Paralysis, or palsy, is a diminution or entire loss of the powers of motion in some parts of the body. In the winter, poor lambs, or poor pregnant ewes, or poor feeble ewes immediately after yeaning in the spring, occasionally lose the power of walking or standing rather too suddenly to have it referable to increasing debility. The animal seems to have lost all strength in its loins, and the hind-quarters are powerless; it makes ineffectual attempts to rise, and cannot stand if placed upon its feet.
Treatment.Warmth, gentle stimulants, and good nursing may raise the patient; but, in the vast majority of cases, it is more economical and equally humane, to deprive it of life at once.
This is often mistaken for the scab, but it is, in fact, a different and less dangerous disease. The wool falls off, and leaves the sheep nearly naked; but it is attended with no soreness, though a reddish crust will cover the skin, from the wool which has dropped. It generally arises from hard keeping and much exposure to cold and wet; and, in fact, the animal often dies in severe weather from the cold it suffers on account of the loss of its coat.
Theremedyis full feeding, a warm stall, and anointing the hard part of the skin with tar, oil, and butter. Some, however, do nothing for it, scarcely considering it a disease. Such say that if the condition of a poor sheep is raised as suddenly as practicable, by generous keep in the winter, the wool is very apt to drop off; and, if yet cold, the sheep will require warm shelter.
Pneumonia—or inflammation of the lungs—is not a common disease in the Northern States; but undoubted cases of it sometimes occur, after sheep have been exposed to sudden cold, particularly when recently shorn. The adhesions occasionally witnessed between the lungs and pleura of slaughtered sheep, betray the former existence of this disease in the animal—though, in many instances, it was so slight as to be mistaken, at the time, for a hard cold.
Symptoms.The animal is dull, ceases to ruminate, neglects its food, drinks frequently and largely, and its breathing is rapid and laborious; the eye is clouded; the nose dischargesa tenacious, fetid matter; the teeth are ground frequently, so that the sound is audible at some distance; the pulse is at first hard and rapid, sometimes intermits, but before death it becomes weak. During the height of the fever, the flanks heave violently; there is a hard, painful cough during the first stages, which becomes weaker, and seems to be accompanied with more pain as death approaches.
After death, the lungs are found more or less hepatized—that is, permanently condensed and engorged with blood, so that their structure resembles that of thehepar, or liver—and they have so far lost their integrity that they are torn asunder by the slightest force. It may here be remarked that when sheep die from any cause,with their blood in them, the lungs have a dark, hepatized appearance. Whether they are actually hepatized or not, can readily be decided by compressing the windpipe, so that air cannot escape through it, and then between such compression and the body of the lungs, in a closely fitting orifice, inserting a goose-quill, or other tube, and continuing to blow until the lungs are inflated as far as they can be. As they inflate, they will become of a lighter color, and plainly manifest their cellular structure. If any portions of them cannot be inflated, and retain their dark, liver-like consistence, and color, they exhibit hepatization—the result of high inflammatory action—and a state utterly incompatible, in the living animal, with the discharge of the natural functions of the viscus.
Treatment.In the first, or inflammatory stages, bleeding and aperients are clearly called for. Some recommend early and copious bleeding, repeated, if necessary, in a few hours; this followed by aperient medicines, such as two ounces ofEpsom salts, which may be repeated in smaller doses, if the bowels are not sufficiently relaxed. The following sedative may also be given with gruel, twice a day: nitrate of potash, one drachm; powdered digitalis, one scruple; and tartarized antimony, one scruple.
While depletion may be of inestimable value during the continuance—the short continuance—of the febrile state, yet excitation like this will soon be followed by corresponding exhaustion, when the bleeding and purging would be murderous expedients; and gentian, ginger, and the spirits of nitrous ether will afford the only hope of cure.
Sheep will often, in the winter or spring, eat greedily of the low laurel. The animal appears afterward to be dull and stupid, swells a little, and is constantly gulping up a feverish fluid, which it swallows again; a part of it will trickle out of its mouth, and discolor its lips. The plant probably brings on a fermentation in the stomach, and nature endeavors to throw off the poisonous herb by retching or vomiting.
Treatment.In the early stages, if the greenish fluid be allowed to escape from the stomach, the animal generally recovers. To effect this, gag the sheep, which may be done in this manner: Take a stick of the size of the wrist, six inches long—place it in the animal’s mouth—tie a string to one end of it, pass it over the head and down to the other end, and there make it fast. The fluid will then run from the mouth as fast as thrown up from the stomach. In addition to this, give roasted onions and sweetened milk freely. A better plan, however, is to force a gill of melted lard down the throat; or, boilfor an hour the twigs of the white ash, and give one-half to one gill of the strong liquor immediately; to be repeated, if not successful. Drenchers of milk and castor-oil are also recommended.
This disease, which sometimes causes the death of a million of sheep, in England, in a single year, is comparatively unknown in this country. It prevails somewhat in the Western States, from allowing sheep to pasture on land that is overflowed with water. Even a crop of green oats, early in the fall, before a frost comes; has been known to rot young sheep.
Symptoms.The first are by no means strongly marked; there is no loss of condition, but rather the contrary, to all appearance. A paleness and want of liveliness of the membranes, generally, may be considered as the first symptoms, to which may be added a yellowness of the caruncle at the corner of the eye. When in warm, sultry, or rainy weather, sheep that are grazing on low and moist lands, feed rapidly, and some of them die suddenly, there is ground for fearing that they have contracted the rot. This suspicion will be farther increased if, a few days afterward, the sheep begin to shrink and grow flaccid about the loins. By pressure about the hips at this time, a crackling is perceptible now or soon afterward, the countenance looks pale, and upon parting the fleece, the skin is found to have changed its vermilion tint for a pale red, and the wool is easily separated from the felt; and as the disorder advances, the skin becomes dappled with yellow or black spots. To these symptoms succeed increased dullness, loss of condition, and greater paleness of the mucousmembranes, the eye-lids becoming almost white, and afterward yellow. This yellowness extends to other parts of the body, and a watery fluid appears under the skin, the latter becoming loose and flabby, and the wool coming off readily. The symptoms of dropsy often extend over the body, and sometimes the sheep becomeschockered, as it is termed; a large swelling forms under the jaw, which, from the appearance of the fluid which it contains, is sometimes called thewatery poke. The duration of the disease is uncertain; the animal occasionally dies shortly after becoming affected, but more frequently it extends to from three to six months, the sheep gradually losing flesh and pining away, particularly if, as is frequently the case, an obstinate purging supervenes.
Post-mortem.The whole cellular tissue is found to be infiltrated, and a yellow serous fluid everywhere follows the knife. The muscles are soft and flabby, having the appearance of being macerated. The kidneys are pale, flaccid, and infiltrated. The mesenteric glands are enlarged, and engorged with yellow serous fluid. The belly is frequently filled with water, or purulent matter; the peritoneum is everywhere thickened, and the bowels adhere together by means of an unnatural growth. The heart is enlarged and softened, and the lungs are filled with tubercles. The principal alterations of structure are in the liver, which is pale, livid, and broken down with the slightest pressure; and on being boiled, it will almost dissolve away. When the liver is not pale, it is often curiously spotted; in some cases it is speckled, like the back of a toad; some parts of it, however, are hard and schirrous; others are ulcerated, and the biliary ducts are filled with flukes. The malady is, unquestionably, inflammation of the liver.This fluke is from three-quarters of an inch to an inch and a quarter in length, and from one-third to one-half an inch in its greatest breadth. These fluke-worms undoubtedly aggravate the disease, and perpetuate a state of irritability and disorganization, which must necessarily undermine the strength of any animal.
Treatment.This must, to a considerable extent, be very unsatisfactory. After the use of dry food and dry bedding, one of the bestpreventivesis the abundant use of pure salt. In violent attacks, take eight, ten, or twelve ounces of blood, according to the circumstances of the case; to this, let a dose of physic succeed—two or three ounces of Epsom salts; and to these means add a change of diet, good hay in the field, and hay, straw, or chaff in the yard. After the operation of the physic—an additional dose having been administered, oftentimes, in order to quicken the action of the first—two or three grains of calomel may be given daily, mixed with half the quantity of opium, in order to secure its beneficial, and ward off its injurious effects on the ruminant. To this should be added common salt, which acts as a purgative and a tonic. A mild tonic, as well as an aperient, is plainly indicated soon after the commencement of rot. The doses should be from two to three drachms, repeated morning and night. When the inflammatory stage is clearly passed, stronger tonics may be added to the salt, and there are none superior to the gentian and ginger roots; from one to two drachms of each, finely pounded, may be added to each dose of the salt. The sheep having a little recovered from the disease, should still continue on the best and driest pasture on the farm, andshould always have salt within their reach. The rot is not infectious.
This is a cutaneous disease, analogous to the mange in horses and the itch in man, and is caused and propagated by a minute insect, theacarus.
The Broad-Tailed SheepTHE BROAD-TAILED SHEEP.
THE BROAD-TAILED SHEEP.
If one or more femaleacariare placed on the wool of a sound sheep, they quickly travel to the root of it, and bury themselves in the skin, the place at which they penetrate being scarcely visible, or only distinguishable by a minute red point. On the tenth or twelfth day, a little swelling may be detected with the finger, and the skin changes its color, and has a greenish blue tint. The pustule is now rapidly formed, and about the sixteenth day breaks, when the mothers again appear, with their little ones attached to their feet, and covered by a portion of the shell of the egg from which they have just escaped. These little ones immediately set to work, penetrate the neighboring skin, bury themselves beneath it, find their proper nourishment, and grow and propagate, until the poor creature has myriads of them preying upon him. It is not wonderful that, under such circumstances, he should speedily sink. The maleacari, when placed on the sound skin of a sheep, will likewise burrow their way anddisappear for a while, the pustule rising in due time; but the itching and the scab soon disappear without the employment of any remedy. The female brings forth from eight to fifteen young at a time.
In the United States, this disease is comparatively little known, and never originates spontaneously. The fact, that short-woolled sheep—like the Merino—are much less subject to its attacks, is probably one reason for this slight comparative prevalence. The disease spreads from individual to individual, and from flock to flock, not only by means of direct contact, but by theacarileft on posts, stones, and other substances against which diseased sheep have rubbed themselves. Healthy sheep are, therefore, liable to contract the malady, if turned on pastures previously occupied by scabby sheep, although some considerable time may have elapsed since the departure of the latter.
The sheep laboring under the scab is exceedingly restless. It rubs itself with violence against trees, stones, fences, etc.; scratches itself with its feet, bites its sores, and tears off its wool with its teeth; as the pustules are broken, their matter escapes, and forms scabs, causing red, inflamed sores, which constantly extend, increasing the misery of the tortured animal; if unrelieved, he pines away, and soon perishes.
Thepost-mortemappearances are very uncertain and inconclusive. There is generally chronic inflammation of the intestines, with the presence of a great number of worms. The liver is occasionally schirrous, and the spleen enlarged; and there are frequently serous effusions in the belly, and sometimes in the chest. There has been evident sympathy between the digestive and the cutaneous systems.
Treatment.First, separate the sheep; then cut off the wool as far as the skin feels hard to the finger; the scab is then washed with soap-suds, and rubbed hard With a shoe-brush, so that it may be cleansed and broken. For this use take a decoction of tobacco, to which add one-third, by measure, of the lye of wood-ashes, as much hog’s lard as will be dissolved by the lye, a small quantity of tar from a tar-bucket, which contains grease, and about one-eighth of the whole, by measure, of spirits of turpentine. This liquor is rubbed upon the part infected, and spread to a little distance around it, in three washings, with an interval of three days each. This will invariably effect a cure, when the disorder is only partial.
Or, the following: Dip the sheep in an infusion of arsenic, in the proportion of half a pound of arsenic to twelve gallons of water. The sheep should be previously washed in soap and water. The infusion must not be permitted to enter the mouth or nostrils.
Or, take common mercurial ointment; for bad cases, rub it down with three times its weight of lard—for ordinary cases, five times its weight. Rub a little of this ointment into the head of the sheep. Part the wool so as to expose the skin in a line from the head to the tail, and then apply a little of the ointment with the finger the whole way. Make a similar furrow and application on each side, four inches from the first; and so on, over the whole body. The quantity of ointment after composition with the lard, should not exceed two ounces; and, generally, less will suffice. A lamb requires but one-third as much as a grown sheep. This will generally cure; but, if the animal should continue to rub itself, a lighter application of the same should be made in ten days.
Or, take two pounds of lard or palm oil; half a pound of oil of tar; and one pound of sulphur; gradually mix the last two, then rub down the compound with the first. Apply as before. Or, take of corrosive sublimate, one half a pound; white hellabore, powdered, three-fourths of a pound; whale or other oil, six gallons; rosin, two pounds; and tallow, two pounds. The first two to be mixed with a little of the oil, and the rest being melted together, the whole to be gradually mixed. This is a powerful preparation, and must not be applied too freely.
An erysipelatous scab, or erysipelas, attended with considerable itching, sometimes troubles sheep. This is a febrile disease, and is treated with a cooling purgative, bleeding, and oil or lard applied to the sores.
The author acknowledges himself indebted for what follows under this head to R. McClure, V. S., of Philadelphia, author of a Prize Essay on Diseases of Sheep, read before the U. S. Agricultural Society, in 1860, for which a medal and diploma were awarded.
Although the small-pox in domestic animals has, fortunately, been as yet confined to the European Continent—where it has been chiefly limited to England—no good reason can ever be assigned why it should not at some future time make its appearance among us, especially when we remember how long a period elapsed, during which we escaped the cattle plague, although the Continent had long been suffering from it.
The small-pox in sheep—variola overia—is, at times, epizoötic in the flocks of France and Italy, but was unknownin England until 1847, when it was communicated to a flock at Datchett and another at Pinnier by some Merinos from Spain. It soon found its way into Hampshire and Norfolk, but was shortly afterward supposed to be eradicated. In 1862, however, it suddenly reappeared in a severe form among the flocks of Wiltshire; for which reappearance neither any traceable infection nor contagion could be assigned. With the present light upon the subject, it would seem to be an instance of the originationanewof a malignant type of varioloid disease. Such an origin is, in fact, assigned to this disease in Africa, it being well established that certain devitalizing atmospheric influences produce skin diseases, and facilitate the appearance of pustular eruptions.
The disease once rooted soon becomes epizoötic, and causes a greater mortality than any other malady affecting this animal. Out of a flock numbering 1720, 920 were attacked in a natural way, of which 50 per cent. died. Of 800 inoculated cases, but 36 per cent. died.
Numerous experiments have proved beyond all doubt that this disease in sheep is both infectious and contagious; its period of incubation varies from seven to fourteen days. The mortality is never less than 25 per cent., and not unfrequently whole flocks have been swept away, death taking place in the early stages of the eruption, or in the stages of suppuration and ulceration.
Thesymptomsmay be mapped out as follows: The animal is seized with a shivering fit, succeeded by a dull stupidity, which remains until death or recovery results; on the second or third day, pimples are seen on the thighs and arm-pits, accompanied with extreme redness of the eyes, completeloss of appetite, etc., etc. It is needless to enumerate other symptoms which exist in common with those of other disorders.
Prevention.At present, but two modes are resorted to, for the purpose of preventing the spread of the disease, which promise any degree of certainty of success. The first is byinoculation, which was recommended by Professor Simonds, of London. This distinguished pathologist appears to have overlooked the fact that he was thereby only enlarging the sphere of mischief, by imparting the disease to animals that, in all probability, would otherwise have escaped it. By inoculation, moreover, a form of the disease is given, not of a modified character, but with all the virulence of the original affection which is to be arrested, and equally as potent for further destruction of others. By such teaching, inoculation and vaccination would be made one and the same thing, notwithstanding their dissimilarity. Even vaccination will not protect the animal, as has been already shown by the experiments of Hurbrel D’Arboval.
The second and best plan of prevention isisolation and destruction, as recommended by Professor Gamgee, of the Edinburgh Veterinary College. This proved a great protection to the sheep-farmers of Wiltshire, in 1862. In all epizoötic diseases, individual cases occur, which, when pointed out and recognized as soon as the fever sets in and the early eruptions appear, should be slaughtered at once and buried, and the rest of the flock isolated. By this means the disease has been confined to but two or three in a large flock.
Treatment.In treating this disease, resort has of late been had to a plant, known asSarracenia purpura—Indian cup,or pitcher plant—used for this purpose by the Micmacs, a tribe of Indians in British North America. This plant is indigenous, perennial, and is found from the coast of Labrador to the shores of the Gulf of Mexico, growing in great abundance on wet, marshy ground. The use of this plant is becoming quite general, and good results have almost uniformly attended it.
Take from one to two ounces of the dried root, and slice in thin pieces; place in an earthen pot; add a quart of cold water, and allow the liquid to simmer gently over a steady fire for two or three hours, so as to lose one-fourth of the quantity. Give of this decoction three wine-glassfuls at once, and the same quantity from four to six hours afterwards, when a cure will generally be affected. Weaker and smaller doses are certain preventives of the disease. The public are indebted to Dr. Morris, physician to the Halifax (Nova Scotia) Dispensary, for the manner of preparing this eminently useful article.
Sheep feeding on pastures infested with John’s wort, frequently exhibit an irritation of skin about the nose and face, which causes the hair to drop off from the parts. The irritation sometimes extends over the entire body. If this plant is eaten in too large quantities, it produces violent inflammation of the bowels, and is frequently fatal to lambs, and sometimes to adults.
Treatment.Rub a little sulphur and lard on the irritated surface. If there are symptoms of inflammation of the bowels,this should be put into the mouth of the sheep with a flattened stick. Abundance of salt is deemed apreventive.
The lips of sheep sometimes become suddenly sore in the winter, and swell to the thickness of a man’s hand. The malady occasionally attacks whole flocks, and becomes quite fatal. It is usually attributed to noxious weeds cut with the hay.
Treatment.Daub the lips and mouth plentifully with tar.
The treatment necessary as a preventive against these insects, and a remedy for them, has already been indicated under the head of “Feeding and Management,” to which the reader is referred.
The Wild Boar
The hog is a cosmopolite, adapting itself to almost every climate; though its natural haunts—like those of the hippopotamus, the elephant, the rhinoceros, and most of the thick-skinned animals—are in warm countries. They are most abundant in China, the East Indies, and the immense range of islands extending throughout the whole Southern and Pacific oceans; but they are also numerous throughoutEurope, from its Southern coast to the Russian dominions within the Arctic.
As far back as the records of history extend, this animal appears to have been known, and his flesh made use of as food. Nearly fifteen hundred years before Christ, Moses gave those laws to the Israelites which have given rise to so much discussion; and it is evident that, had not pork been the prevailing food of that nation at the time, such stringent commandments and prohibitions would not have been necessary. The various allusions to this kind of meat, which repeatedly occur in the writings of the old Greek authors, show the esteem in which it was held among that nation; and it appears that the Romans made the art of breeding, rearing, and fattening pigs a study. In fact, the hog was very highly prized among the early nations of Europe; and some of the ancients even paid it divine honors.
The Jews, the Egyptians, and the Mohammedans alone appear to have abstained from the flesh of swine. The former were expressly denied its use by the laws of Moses. “And the swine, though he divide the hoof, and be cloven-footed, yet he cheweth not the cud; he is unclean unto you.” Lev. xi. 7. Upon this prohibition, Mohammed, probably, founded his own. For the Mosaic prohibition, various reasons have been assigned: the alleged extreme filthiness of the animal; it being afflicted with a leprosy; the great indigestibility of its flesh in hot climates; the intent to make the Jews “a peculiar people;” a preventive of gluttony; and an admonition of abstinence from sensual and disgusting habits.
At what period the animal was reclaimed from his wild State, and by what nation, cannot be stated. From theearliest times, in England, the hog has been regarded as a very important animal, and vast herds were tended by swineherds, who watched over their safety in the woods, and collected them under shelter at night. Its flesh was the staple article of consumption in every household, and much of the wealth of the rich and free portion of the community consisted in these animals. Hence bequests of swine, with land for their support, were often made; rights and privileges connected with their feeding, and the extent of woodland to be occupied by a given number, were granted according to established rules. Long after the end of the Saxon dynasty, the practice of feeding swine upon the mast and acorns of the forest was continued till the forests were cut down, and the land laid open for the plough.
Nature designed the hog to fulfil many important functions in a forest country. By his burrowing after roots and the like, he turns up and destroys the larvæ of innumerable insects, which would otherwise injure the trees as well as their fruit. He destroys the slug-snail and adder, and thus not only rids the forests of these injurious and unpleasant inhabitants, but also makes them subservient to his own nourishment, and therefore to the benefit of mankind. The fruits which he eats are such as would otherwise rot on the ground and be wasted, or yield nutriment to vermin; and his diggings for earth-nuts and the like, loosens the soil, and benefits the roots of the trees. Hogs in forest land may, therefore, be regarded as eminently beneficial; and it is only the abuse which is to be feared.
The hog is popularly regarded as a stupid, brutal, rapacious, and filthy animal, grovelling and disgusting in all his habits,intractable and obstinate in temper. The most offensive epithets among men are borrowed from him, or his peculiarities. In their native state, however, swine seem by no means destitute of natural affections; they are gregarious, assemble together in defence of each other, herd together for warmth, and appear to have feelings in common; no mother is more tender to her young than the sow, or more resolute in their defence. Neglected as this animal has ever been by authors, recorded instances are not wanting of their sagacity, tractability, and susceptibility of affection. Among the European peasantry, where the hog is, so to speak, one of the family, he may often be seen following his master from place to place, and grunting his recognition of his protectors.
The hog, in point of actual fact, is also a much more cleanly animal than he has the credit of being. He is fond of a good, cleanly bed; and when this is not provided for him, it is oftentimes interesting to note the degree of sagacity with which he will forage for himself. It is, however, so much the vogue to believe that he may be kept in any state of neglect, that the terms “pig,” and “pig-sty” are usually regarded as synonymous with all that is dirty and disgusting. His rolling in the mud is cited as a proof of his filthy habits. This practice, which he shares in common with all the pachydermatous animals, is undoubtedly the teaching of instinct, and for the purpose of cooling himself and keeping off flies.
Pigs are exceedingly fond of comfort and warmth, and will nestle together in order to obtain the latter, and often struggle vehemently to secure the warmest berth. They are likewise peculiarly sensitive of approaching changes in the weather, and may often be observed suddenly leaving the places inwhich they had been quietly feeding, and running off to their styes at full speed, making loud outcries. When storms are overhanging, they collect straw in their mouths, and run about as if inviting their companions to do the same; and if there is a shed or shelter near at hand, they will carry it there and deposit it, as if for the purpose of preparing a bed.
In their domesticated state, they are, undeniably, very greedy animals; eating is the business of their lives; nor do they appear to be very delicate as to the kind or quality of food which is placed before them. Although naturally herbivorous animals, they have been known to devour carrion with all the voracity of beasts of prey, to eat and mangle infants, and even gorge their appetites with their own young. It is not, however, unreasonable to believe that the last revolting act—rarely if ever happening in a state of nature—arises more from the pain and irritation produced by the state of confinement, and often filth, in which the animal is kept, and the disturbances to which it is subjected, than from any actual ferocity; for it is well known that a sow is always unusually irritable at this period, snapping at all animals that approach her. If she is gently treated, properly supplied with sustenance, and sequestered from all annoyance, there is little danger of this practice ever happening.
All the offences which swine commit are attributed to a disposition innately bad; whereas they too often arise from bad management, or total neglect. They are legitimate objects for the sport of idle boys, hunted with curs, pelted with stones, often neglected and obliged to find a meal for themselves, or wander about half-starved. Made thus the Ishmaelites of our domestic animals, is it a matter of wonder thatthey should, under such circumstances, incline to display Ishmaelitish traits? In any well-regulated farm-yard, the swine are as tractable and as little disposed to wander or trespass as any of the animals that it contains.
Thewild boaris generally admitted to be the parent of the stock from which all our domesticated breeds and varieties have sprung. This animal is generally of a dusky brown or iron-gray color, inclining to black, and diversified with black spots or streaks. The body is covered with coarse hairs, intermixed with a downy wool; these hairs become bristles as they approach the neck and shoulders, and are in those places so long as to form a mane, which the animal erects when irritated. The head is short, the forehead broad and flat, the ears short, rounded at the tips, and inclined toward the neck, the jaw armed with sharp, crooked tusks, which curve slightly upward, and are capable of inflicting fearful wounds, the eye full, neck thick and muscular, the shoulders high, the loins broad, the tail stiff, and finished off with a tuft of bristles at the tip, the haunch well turned, and the leg strong. A full-grown wild boar in India averages from thirty to forty inches in height at the shoulder; the African wild boar is about twenty-eight or thirty inches high.
The wild boar is a very active and powerful animal, and becomes fiercer as he grows older. When existing in a state of nature, he is generally found in moist, shady, and well-wooded situations, not far remote from streams or water. In India, they are found in the thick jungles, in plantations of sugar-cane or rice, or in the thick patches of high, long grass. In England, France, Germany, Italy, and Spain, their resorts have been in the woods and forests. This animal is naturallyherbivorous, and appears to feed by choice upon plants, fruits, and roots. He will, however, eat the worms and larvæ which he finds in the ground, also snakes and other such reptiles, and the eggs of birds. They seldom quit their coverts during the day, but prowl about in search of food during twilight and the night. Their acute sense of smell enables them to detect the presence of roots or fruits deeply imbedded in the soil, and they often do considerable mischief by ploughing up the ground in search of them, particularly as they do not, like the common hog, root up a little spot here and there, but plough long, continuous, furrows.
The wild boar, properly so called, is neither a solitary nor a gregarious animal. For the first two or three years, the whole herd follows the sow, and all unite in defence against any enemies, calling upon each other with loud cries in case of emergency, and forming in regular line of battle, the weakest occupying the rear. When arrived at maturity, the animals wander alone, as if in perfect consciousness of their strength, and appear as if they neither sought nor avoided any living creature. They are reputed to live about thirty years; as they grow old, the hair becomes gray, and the tusks begin to show symptoms of decay. Old boars rarely associate with a herd, but seem to keep apart from the rest, and from each other.
The female produces but one litter in the year, much smaller in number than those of the domestic pig; she carries her young sixteen or twenty weeks, and generally is only seen with the male during the rutting season. She suckles her young for several months, and continues to protect them for some time afterward; if attacked at that time, she will defendherself and them with exceeding courage and fierceness. Many sows will often be found herding together, each followed by her litter of young; and in such parties they are exceedingly formidable to man and beast. Neither they nor the boar, however, seem desirous of attacking any thing; and only when roused by aggression, or disturbed in their retreat, do they turn upon their enemies and manifest the mighty strength with which Nature has endowed them. When attacked by dogs, the wild boar at first sullenly retreats, turning upon them from time to time and menacing them with his tusks; but gradually his anger rises, and at length he stands at bay, fights furiously for his life, and tears and rends his persecutors. He has even been observed to single out the most tormenting of them, and rush savagely upon him. Hunting this animal has been a favorite sport, in almost all countries in which it has been found, from the earliest ages.
