TABLE OF APPROXIMATE EQUIVALENT MEASURES., PREFACE. The following Manual is designed to be a hand-book for Amer- ican shepherds and farmers. It is intended te be so plain that a farmer, or a farmer's son, who has never kept a sheep, may learn from its pages how to manage a flock successfully, and to be so complete that even the experienced shepherd may gather some suggestions from it. When the author, some years ago, began to keep sheep, he sought in vain amongst the published works a simple practical, comprehensive book upon sheep and sheep-keep- ing, suited to his necessities. The excellent works upon the Merino and Fine Wool Husbandry by Mr. Randall, were the only ones to be obtained that were adapted for the use of an American shepherd, and these referred to a special branch of sheep husbandry which is becoming every year a less and less prominent one. The other books on this subject then extant, were either English works or compilations from them, and were out of date and incomplete. None of the works gave a description of the modern improved breeds of sheep which have of late become so deservedly popular ; or any full or satisfactory account of the diseases of sheep, and the remedies proper for them under the modern systems of treat- ment which have grown out of the more accurate scientific knowl- edge of the present day ; nor could any information as to the vastly increased scope of this branch of agricultural industry in America, be found in any book. It was necessary to learn by experience — in this case, as in all others, a costly teacher — how to meet the needs of the modern improved sheep in our climate and (5) YI THE SHEFHEED'S MANUAL. under our methods of culture. The results of personal experi- ences of some years with the characters of the various modern breeds of sheep, and the sheep-raising capabilities of many portions of our extensive territory and that of Canada, most of which have been visited with a view to the effects upon our sheep of the va- rying climate and different soils ; and the careful study of the dis- eases to which our sheep are chiefly subject, with those by which they may eventually be afflicted through unforeseen accidents ; as well as the methods of management called for under our circum- stances, were finally gathered into the shape in which they are here presented to the shepherds of America, with the hope that they may be as acceptable and useful to them as they would have been, when he first undertook the care of a flock, to THE AUTHOB. NEW YOKE., 1370. The Shepherd's Manual. CHAPTER I. THE SHEEP AS AN INDUSTRIAL PRODUCT. From the earliest ages the sheep has been a source of profit to mankind, and its keeping and rearing an important industry. Abel, the second son of Adam, chose sheep-herding as his employ- ment, and although his elder brother chose to cultivate the soil, the pastoral life became the favored occupation of the human race in its early periods, and the more toilsome tillage of the ground was followed from necessity rather than from choice. With a sparse population, a scarcity of labor, but at the same time an ample territory, the cultivation of flocks became in early times the readiest means of providing food and clothing, increasing the com- forts of man and of accumulating transferable wealth. Although at first sight it is a singular circumstance, yet on reflection it is seen to be a necessity of the case that the territory upon which the flocks of the ancient patriarchs were fed and tended, is still the home of shepherds, and that there, for forty centuries, flocks have wandered from pasture to pasture under the care of their nomadic proprietors. Where the physical features of the country were favorable to pasturage, there the first civilized occupation was that of keeping sheep, and so it remains to this day. In view of its bearing upon the future of sheep husbandry in the United States, it is important to remember this fact, that where peculiarly favorable physical features of the country were present, and the shepherd occupied the land, there the shepherd and his flock retain possession until this day. Thus, at the time of the conquest of Spain by the ancient Romans, that country was cele- brated for its flocks and the quality of its wool, and to-day the (7) 8 THE SHEPHERD'S MANUAL. Spanish Merino is equally celebrated, although through adventi- tious circumstances, but chiefly political disturbances, its pre-emi- nence has been lost to Spam, and other countries enjoy its fruits. As civilization progressed stage by stage, and garments of man- ufactured wool displaced those of skins, careful breeding began to improve the fleece, and varieties among sheep became fixed in type. Before the Christian era the fine wools of Italy were noted, and the fineness of the fleece was cultivated to a degree unknown to us of the present day. The sheep of that period were housed and clothed, their skins were oiled and moistened with wine, and their fleeces were combed and washed repeatedly, in order that the quality of the wool might be refined as far as possible. Al- though this excessive refinement destroyed the vigor and impaired the constitution of the sheep, yet their descendants, inferior in form, as might be expected, are still fine-wooled sheep. Thus far the improvement in sheep operated only towards refining the fleece, and the carcass was a secondary object, only cared for so far as it could serve as a vehicle for carrying the wool. The lamb of the flock was considered a choice morsel, but the mature sheep was neglected as an article of food. It is only in recent times that the excellence of mutton has been made an object hi the improve- ment of sheep. At the present it is only in sparsely populated countries that sheep are cultivated for wool alone, while in densely peopled localities the production of mutton is of greater consider- ation than that of wool, or at least is of equal value to it. At the present time, proximity to, or distance from market, decides the choice of breeds, and in fact this consideration alone has in some cases been the moving influence in the creation of new varieties or breeds specially adapted to certain localities. In a similar man- ner the necessities of sheep-breeders have led them to make some important modifications in their methods of agriculture, so that while the character of their flocks has been changed for the better, their agriculture has been improved, the product of the land in- creased, and its value advanced, until profitable sheep culture has become synonymous with the most profitable farming. In fact, the character of the farm has been indexed by the character of the flock reared upon it. This improvement has in greater part oc- curred only in connection with the rearing of mutton sheep. To feed these heavy bodied sheep profitably, it has been found neces- sary to raise large crops of cheap roots and luxuriant green crops ; and to raise these crops, the most skillful tillage, the cleanest cul- ture, and the most liberal manuring have been requisite. In this way the product of the soil has been vastly increased, and the PRODUCTION OF MUTTON. 9 sheep, directly and indirectly, has been both the gainer and the means of gain. The demand for mutton as an agreeable and cheap food is stead- ily increasing. The markets of the city of New York alone re- quire more than one million sheep per annum. Farmers formerly habituated to the daily use of pork are becoming mutton eaters, and the convenience of a few sheep upon the farm merely to sup- ply the family table is now appreciated to a much greater extent than ever before. This cultivation of sheep for mutton alone is a branch of agriculture which is yearly becoming more important. As yet we possess no native variety of mutton sheep. The carcass of the "native " sheep, so called— but which is really a heterogeneous mixture of all those breeds which have been brought to this coun- try, and which having been permitted to increase promiscuously, have perpetuated only their poorest qualities— is unworthy the name of mutton ; and those flocks of imported sheep of better character, such as the Southdowns, Leicesters, or Cotswolds, are either allowed to deteriorate, or are kept for breeding purposes. It is very true that a really good carcass of mutton rarely finds its way to our markets, except from Canada, where almost the sole attention is given to breeding sheep for mutton. At the same time there is a demand for mutton, both of that substantial kind which is represented by legs of 16 to 20 Ibs. in weight, handsome saddles and good shoulders, and that more delicately flavored kind repre- sented by the small legs or quarters of the Welsh sheep. Unfortunately this fact is not generally known to farmers, and if it were, it is equally unfortunate that we as yet have not the kind of sheep to meet the demand. Before this excellent and wholesome food can become as popular as it ought to be, and sheep keeping can become as profitable as it may be, farmers must be better informed as to the character of the sheep needed, the manner in which they may be bred, and the methods by which they may be fitted for the market This necessary information must include a knowledge of the modern breeds which have usurped the place of the old kinds, and the peculiar management of the new races of sheep, as well as of the special crops needed for fodder, and the methods of cultivating them. Heretofore in place of this practical information, American farmers have been treated to long dissertations upon the origin and history of the sheep, and descriptions of foreign breeds which are of no possible value or interest to them. The sheep, in addition to its value as a food producer, yields to its owner an annual tribute in the shape of its fleece, which in the 10 aggregate is a most important contribution to the comfort and in- dustry of the people. In 1870 there were nearly 30 millions of sheep in the United States, and the wool production in that year amounted to 120 million pounds, estimating the average weight of the fleeces at 4 pounds each. The value of this wool in the farm- ers' hands would reach at the lowest estimate, $40,000,000. But so far from being anywhere equal to the demand for this staple, the supply was less than our yearly needs by a quantity equal to a value of more than $40,000,000, and wool to this amount is annu- ally imported from foreign countries. Besides this in wool, there is annually imported with it the value of $20,000,000 in foreign la- bor, which has been expended in manufacturing wool into cloth and other woolen goods. Our own necessities, therefore, demand an increase in the supply of wool equal to our present production. This wool, if produced here, would not only use up a large quan- tity of corn now. thrown upon the markets of the world, and therefore enhance the value of that which would remain for dis- posal ; but its manufacture into cloths and goods would employ a large number of persons who are now engaged in raising agricul- tural products for sale, and are therefore in active competition with other farmers. The encouragement of sheep cultivation, therefore, has a national importance, and is a subject which bears directly upon the interests of farmers. To increase the wool pro- duct to a par with the necessities of the country at the present time, would alone involve the passage through their hands of '$60,000,000 yearly — an immense sum, which now goes into the pockets of foreigners, instead of those of our own people. The scope for an increase in our wool product is comparatively boundless. A full third of the territory of the United States is a grand sheep pasture of the most favorable character. Vast plains bearing abundance of the most nutritious herbage, in the most healthful climate, and the very best conditions for the profitable breeding of fine and middle wool sheep, and which are valueless for any other than pastoral purposes, stretch from the 100th me- ridian for 500 miles west to the Rocky Mountains, and from north to south for 1,500 miles. In addition to this vast tract, upon which a hundred million sheep could feed and thrive with ease, there are immense mountain ranges, extensive valleys, and again beyond these, great plains, altogether covering a still larger area, of which a great portion is admirably fitted for the pasturing of sheep. With so great a scope for the cheap production of wool, it seems to be a strange thing, that instead of exporting largely of this staple, as we might and should do, the United States on the contrary is one PRODUCTION OF WOOL. 11. of the largest buyers in foreign markets. Again, on the Atlantic seaboard there are millions of acres of land now useless that would, if cleared and cultivated, make excellent sheep farms for the pro- duction of the choicest mutton sheep. There are numberless salt marshes upon which sheep, naturally fitted through long years of adaptation for just such pasturage, could be made to yield mutton of the most delicate flavor. There are also hills and rocky moun- tains upon whose sweet herbage hardy races of sheep could be made to thrive with profit ; and further inland, highly cultivated farms, where heavy crops of green fodder and roots could be raised, that might carry flocks of large framed sheep, yielding combing W0ol — now so much used in clothing materials for both sexes, and the demand for which is always ahead of the supply. And further south, where it is possible to pasture sheep the year round, but where those which are now kept are so neglected that some of them are never shorn, there is .also vast room to change the overdone cotton production for the equally easy but more profitable production of wool which in that climate, by the exercise of proper care, may be grown of the finest quality of staple. What a vast field opens upon our view when we consider the extent of the territory which we possess suitable for sheep cul- ture ; and what profit and increase of national wealth is there in this business to those who undertake it as the occupation of their lives — not only for a short period and intermittingly, and then to be abandoned for some other temporary speculative business — but with a desire and determination to succeed through the exercise of patience, perseverance, and skill. CHAPTEE II. SUMMER MANAGEMENT OF SHEEP. The selection of a suitable farm should be the first care of a person who intends to devote his time and capital to the rearing of sheep. To become a successful shepherd, requires that a person should have a liking for the business, and possess tact, patience, and perseverance sufficient to resist the temptations which may arise at seasons of depression to abandon it for some other tempo- rarily more promising pursuit. Having a determination to stick 12 THE SHEPHERD'S MANUAL. to his flock, he must have a farm suited to its special needs or it will not thrive. Sheep cannot bear damp ; and undrained pastures are fatal to their welfare. Luxuriance of herbage is not generally favorable unless the land is heavily stocked and the pasture kept short and closely cropped. Old permanent meadows, in which a variety of grasses are found, are better than artificial meadows which form part of a rotation with other crops. With a portion of such permanent meadow, there may be many cultivated crops grown upon the other portions of the farm upon which the sheep may be folded with benefit both to themselves and the land. The land most suitable for sheep is one that is naturally drained, with a sandy loam or gravelly soil and subsoil, and which bears spontaneously short, fine, herbage, largely mixed with white clover. It should be rolling, and may be hilly in character rather than flat and level. Any low spots or hollows in which aquatic or marsh plants grow, are very objectionable, and should be thoroughly drained. One such spot upon an otherwise admirable farm may infect a flock with deadly disease. No domestic animal is more readily affected by adverse circumstances than the sheep, and none has less spirit or power to resist them. Virgil, the ancient poet, a close observer of such matters, says of them, " Oves semper infelix pecus" (Sheep are always an unhappy flock), and many shepherds since his day have found reason to hold the same belief. But the experienced sheepmaster has no fear on this score. He knows that a reputation for success with sheep is " never gained without merit, nor lost without deserving," and that failure is not want of luck, as is so frequently declared, but the consequence of ignor- ance or bad management. The careful shepherd will not wait to cure, he is prompt to prevent ; and every defeat is made a new lesson for study and an example for future avoidance. It is by long experience that shepherds have learned that the first requi- site for success in their business is, the choice of a farm upon which their flocks will enjoy perfect health, and that dry ness of soil and of air is the first necessity for their well being. By a careful and judicious choice in this respect, most of the ills to which sheep are subject, with all their contingent losses to their owners, are avoided. The character of the soil upon which sheep are pastured has a great influence in modifying the character of the sheep. Upon the kind of soil of course depends the character of the herbage upon which the flock feeds. Certain soils, such as those consist- ing of decomposed granite or feldspar, and which are rich in pot- ash, are not generally favorable for sheep. Even turnips raised on ON SOILS. 13 such lands sometimes affect the sheep injuriously, producing dis- ease under which they waste away, become watery about the eyes, fall in about the flanks, and assume a generally unhealthy appear- ance. Upon removal to a limestone, or a dry sandstone soil, sheep thus affected, improve at once and rapidly recover. The lambs, as might be expected, are most easily affected, and many are yearly lost by early death upon lands of an unfavorable character. As a rule, lands upon which granite, feldspathic or micaceous rocks intrude, or whose soils are derived from the degradation of such rocks, should be avoided by the shepherd. Such soils are, however, not without their uses, and fortunately are excellently adapted to the dairy. The soils most to be preferred are sandstone and lime- stone lands, of a free, dry, porous character, upon which the finer grasses flourish. The soils which are derived from rocks called carboniferous, which accompany coal deposits, or are found in the regions in which coal is mined, are those upon which sheep have been bred with the most success. The original home of the Lei- cester sheep, as well as that of the famous Shropshires, is on the red sandstone ; the Lincoln is raised on the alluvial soils based on limestone ; the Cotswold has had its home for centuries on the limestone Cotswold hills ; the Southdown, Hampshiredown, and Oxforddowns, are native to the chalk hills and downs of southern England ; the Scotch Cheviot and the hardy black-faced Scotch sheep thrive on sandstone hills and mountains of trap rocks which rise amongst them ; the fine wools of Yorkshire are produced on magnesian limestone soils ; and to come to our own soils, we find the American Merino reaching perfection on the limestone hills of Vermont, beneath which fine marbles are quarried. Unfortu- nately this is the only instance we possess of having given a local habitation to a race of sheep in America ; but how soon we shall have produced or acclimated several breeds of sheep, which will take their peculiarities from the locality in which they are bred and raised, is only a question of time. Peat or marsh lands are unfavorable for sheep farms. Salt marshes near the coast, how- ever, may be excepted from this general condemnation, as the saline herbage acts as a specific against some of the parasitic dis- eases— the liver-rot mainly — to which sheep are subject upon marshy pastures. The Romney-marsh sheep of England are bred successfully upon the alluvial soils of reclaimed marshes, and pro- duce good wool and a heavy carcass. The gigantic Lincoln, the largest sheep bred, originated and thrives in perfection upon drained alluvial soils. The dry, friable nature and porous character of the soil has as 14 THE SHEPHERD'S MANUAL. much to do with the health and growth of sheep as the geological character of the rocks upon which it is based, or from which it has been derived. The census returns of England show that the high- est percentage of sheep to the 100 acres, is found precisely NY here the soil is naturally drained and dry, and the lowest, where clay abounds, and damp, cold soils with rank, coarse herbage are gen- eral. In our own country, although the time has been far too short as yet for this condition to operate largely, we find the same fact curiously developed, and Ohio and western Pennsylvania, with their extensive coal bearing formations underlying dry roll- ing fields, possess more sheep than any other district, while New York, Illinois, Indiana, and Michigan, which cover an extensive deposit of limestones and sandstones, with naturally dry soils, come next on the list. The vast stretch of prairies in the Mississippi Valley, and of plains west of the Missouri to the Rocky Moun- tains, chiefly underlaid with limestones and sandstones, and especi- ally remarkable for a dry, porous soil, which bears a rich carpet of the best sheep pastures in the world, have already proved them- selves to be well adapted to the successful growth of flocks bear- ing fine and medium wools. The rich alluvial valleys of the east- ern rivers where naturally or artificially drained, have been found to be fitted for the production of large bodied sheep bearing the lustrous combing wools. All these localities with the hills and valleys of the Middle States will in course of time have their flocks suitable in character to the circumstances in which they are kept. But it will only be in consequence of persistence in careful breed- ing and culture, that the final type for each locality will be reached ; for while the effects of soil and locality are unavoidable and imperative, the shepherd must be able to discover these effects and aid in giving them their due development if early success is to be secured. But in whatever locality it may be, if the soil is not naturally drained, profitable sheep farms may be sought in vain. The profit from sheep raising as a special business will not permit of high-priced lauds. Where sheep are kept only as a branch of general farming, it may pay to drain the soil artificially ; but without drainage, natural or artificial, sheep cannot thrive. The sheep must have a dry foot or disease follows. The character of the herbage depends upon that of the soil, and the character of the sheep is governed by that of the pasture. It is a very casual observer who thinks that all kinds of grass are the same, and are equally proper for sheep. The sheep itself knows better than this, and every shepherd has learned that his sheep will seek particular spots in preference to others in the ON PASTURES. 15 same field. It has been well said that " the dead earth and the living animal are but links of the same chain of natural existences, the plant being the connecting bond by which they are tied to- gether." The flesh and wool of the sheep, therefore, are but pro- ducts from the soil, and contain nothing but what has existed in the plants which the sheep have consumed. When wool is clean and dry, 100 pounds of it contain 17 pounds of nitrogen, and 5 pounds of sulphur. When the pasture is sufficiently nutritious and the sheep is in good health, a quantity of soapy, greasy matter, called yolk, adheres to the fleece. When this is abundant it is a proof that the food of the sheep is healthful and sufficient. When it is deficient, and the wool is harsh and dry to the touch, it is a sign that the sheep's health is suffering from defective nutriment. This yolk contains a large proportion of potash. To be properly nutritious, the food must contain this needed sulphur and pot- ash, along with nitrogen . and other necessary matters. A fair test of the requisite quality of the food of the sheep may be taken from the composition of the flesh and blood of the animal, for there is nothing in the flesh, skin, bones, or wool that does not exist in the blood. The following are the inorganic or mineral materials contained in the ash of the blood and flesh of an animal : Blood. Flesh. Phosphate of Soda 16.77 45.10 Chloride of Sodium 59.34 ) ,- «.

The excre- ment, both solid and liquid, of the sheep contain a large variety of mineral elements, which are also necessary to the healthful animal economy. The urine contains two per cent of mineral matter, and the dung 13| per cent, the composition of which is as follows : ASH OF URINE.

The grasses or other herbage upon which the sheep subsist, must there- fore be such as will supply the peculiar needs of the animal, or they must be supplemented by additional food. When sheep feed upon grasses deficient in the required earthy matters, they become weak in constitution, and predisposed to disease. To prevent dis- ease and keep the flock in health, the pasture must be supple- mented by other feed which will supply the deficiency, and thus the cost of maintaining the flock is increased. A pasture that will supply all the necessary nutriment must contain those varieties of grasses that have been found by experience most suitable for sheep. Of the common grasses there are several varieties which have a high reputation for this purpose. The best of these are of a low growth and creeping habit, with fine, short herbage. The grasses known as PJileum pratense, (Timothy) ; Arrhenatherum ave~ naceum, (Tall Oat Grass); Poa annua, (Annual Spear Grass); Poa pratensis, (Kentucky Blue Grass) ; Festuca ovina, (Sheep's Fes- cue) ; Poa serotina, (False Red-Top) ; Agrostis vulgaris, (Red-Top) ; Dactylis glomerata, (Orchard Grass,) when closely pastured ; Alope- curus pratensis, (Meadow Foxtail,) with Trifolium repem, (White Clover) ; or Plantago lanceolata, (the Narrow-leaved Plantain or Rib Grass,) and some other common plants, form a desirable herbage for sheep. The Buffalo Grass and the species of Bouteloua, com- monly called mesquit grasses of the west, with the large variety of leguminous wild plants, make up a pasture that cannot be excelled. The occasional dressing of pastures with bone-dust, salt, and sul- phate of lime, is of great service, and furnishes a supply of those mineral matters which are indispensable. The value of the different pasture grasses are -shown by the fol- VALUE OF VAEIOUS GRASSES. 17 lowing table of analyses made by Professor Way.

Some of the less nutritious kinds are greedily eaten by sheep, and in furnishing a change of diet, as well as by reason of their aromatic properties, help to stimulate the appetite and preserve the health. Besides the grasses and other plants mentioned, there are sev- eral having an aromatic or astringent character, which are pur- posely introduced into pastures for their medicinal effect upon the sheep. Parsley, Yarrow, and Wormwood are the plants chiefly so used. Pcirsley, (Garum Petrosetinum, or Petroselinum sativum, of the older authors), is a biennial plant well known as a garden herb. It is greedily eaten by sheep, and acts upon the liver and kidneys, or is so supposed to act ; for this reason it has been con- sidered and recommended by shepherds as a preventive of those 18 THE SHEPHERD'S MANUAL. diseases known as " rot," and red water. Hares and rabbits, which are also subject to the rot, and the presence of the accompanying parasite, the " liver fluke," will travel long distances in quest of this herb, and ground upon which it abounds will very soon be eaten bare by them. For these reasons it is usual in England to sow one pound of seed per acre in permanent pastures where it reproduces itself from seed. It is a biennial plant seeding the ; second year of its growth. Yarrow, (Achillea MillefoUum), a plant of the order to which chamoinile belongs, is a perennial bitter astringent herb natural- ized in this country from Europe. Sheep are greedily fond of it, and it is not to be doubted that this instinctive desire is prompted by a natural need for it, not so much as a food, but as a medicine and a tonic. It is usually sown in out of the way places on the borders of pastures or lanes to which sheep have access, and where they can go when instinctively desirous of the plant without being driven, and so that it may not become troublesome as a weed by unduly spreading in the pasture. It thrives best on sandy banks or the hilly borders of woods upon sandy soil. The Ox Eye Daisy, (Chrysanthemum Leucanihemum), a plant of the same botan- ical order with the Yarrow, is also readily cropped by sheep, the blossoms being especially attractive to lambs. Another related plant, the well known Mugwort, (Artemisia vulgaris\ sometimes, but improperly, called wormwood, also naturalized here from Europe, is greedily eaten by sheep. It is also bitter and aromatic and tonic rather than nutritive.

In addition there are several varieties of sea weed and other maritime plants which grow upon GRASSES OF THE PLAINS. 19 the shores that are useful for the subsistence of sheep. These plants are rich in the mineral constituents of common salt, in starch and albumen, and in some localities, flocks of sheep upon the sea coasts and islands exist wholly upon this adventitious pas- turage. A notable case is stated in a recent publication, of a large flock of several hundred sheep which, for years, has subsisted and thrived wholly upon sea weed and wild herbage on an island off the coast of Maine, and there are many others in which farmers adjacent to the sea coast in that state and other parts of New England, subsist their sheep chiefly during the winter upon the sea weed which is cast upon the shores. These cases, however, are only valuable as showing how these really hardy and easily accli- mated animals may be made to thrive and yield their valuable pro- ducts of food and clothing, under the poorest conditions as surely, if not with equal profit, as under the most favorable circumstances. The value of the herbage which covers the wide plains of the west cannot be predicated as yet from any chemical analysis or scientific examinations. In the light of practical experience we do not need these useful aids and helps. The fact that the grasses which cover those plains have supported and fattened countless millions of buffalo and antelope, and the experience already gained in keeping sheep on the plains, are amply sufficient to attest the nutritive value of those grasses. The Buffalo-grass, (Buchloe dao tyloides), is one of the most nutritious of all grasses. Its creeping root stems are always green and of great sweetness. It is low in its habit as suits a pasture for sheep, and furnishes good feeding the year round. Stock that have fed upon it without any help from other feed have been found in spring fat and in condition for the butcher. Meat produced upon this pasture has a delicate flavor, is tender, and has solid fat. Milk from cows fed upon it bears a cream of the richest character and the highest color. It prof ers dry, light soils, which are the very best soils for sheep pastures, and it forces its roots to a depth, or several feet beneath the surface, where it finds moisture even upon the dry plains where the annual rain -fall is scarcely equal to 10 inches. One of the several kinds called " Bunch-grass," (Festuca scabrelld), is another valuable grass common in these regions. It is exceedingly nutritive and cures on the stalk, thus affording winter pasture. Other species of Fes- tuca are common, " Sheep' s-fescue " already noted, being abun- dant. For hay for winter use there are many varieties of highly nutritious grass. Indian or Wood-grass, (Sorghum nutans), is four to five feet in hight, and is full of a rich, sweet juice, which is very palatable and nutritious. There are several other grasses of almost 20 equal value which enable the flock-master to provide abundant supplies of hay to carry his stock over those short periods when pasturing is prevented by snow storms. The variety of native grasses suitable for sheep pastures is thus seen to be ample, and no country in the world is better provided, while few countries are so well supplied with them, as are the United States and territories over the whole length and breadth of their vast surface. The stocking of the pasture must be closely looked to. Over- stocking causes scarcity of pasture, and a deficient supply of nu- triment. It also causes the sheep to take up much sand and earth into their stomachs with their food, which gives them an unthrifty appearance, and sometimes induces disease and death. Sheep pastured on overstocked fields may be recognized by the worn condition of their teeth, and cases have occurred in which this test has indicated a difference of two years in their age. Four-year- old sheep have exhibited the worn mouths of six-year-olds. Un- derstocking is an error on the other side. Unless the pasture is closely cropped, the herbage becomes hard, unpalatable, and indi- gestible, and the sheep do not thrive upon it. It is a well proved adage that " 24 hours' grass is best for a sheep, and 8 days' grass for an ox. " This indicates that the close bite of a sheep should be accommodated by a very close herbage. Tne tender growth of a thick, short pasture is precisely what is wanted, and if the flock is not numerous enough to keep it short, the field should be divided into plots, and those not cropped closely should be pastured down by cattle or left to be mowed. For the better stocking of the pas- tures it would be well, if practicable, to divide the flock, sorting lambs and yearlings from wethers and aged ewes, and putting the former upon the best and tenderest pasture. This is a point of great importance in the management of a flock, and should be clone whenever the welfare of the younger or less vigorous sheep requires it. Where the range is extensive, and ample pasture is provided, any supplementary provision further than an occasional feed of corn, oats, bran, or oil-meal, is unnecessary. These addi- tional foods should be supplied whenever the condition of the pas- ture requires it, and constant watchfulness should be exercised to discover the moment when the pastures fail. It is not that the growth of the sheep is arrested then, but the quality of the wool suffers from the moment that the condition of the sheep begins to deteriorate. The secretion which supplies the matter of which the wool is formed, is then lessened, and the fiber is weakened at that particular spot. If the adverse condition continues for some days or weeks, the weakened fiber forms what is called a " break " SUPPLY OF WATER. 21 in the wool. When the wool comes to be carded or combed, the tension overcomes the resistance of the fiber which breaks at this weak spot, and the broken fibers go to waste. " Break " in the wool greatly reduces its value, and as it is wholly caused by defi- cient nourishment or excessive exposure, it is a loss readily avoided by proper care. The extra supply of food must be judiciously proportioned to the needs of the sheep, as over supply will result in an equal disadvantage by unduly stimulating the condition arid leading to a reaction when the stimulus is withdrawn. Evenness in the fleece, although it may be of poor quality, is better than un- evenness, for even if there be only one short break in a fiber otherwise of general excellence, the whole is reduced by this single break to one-half Us proper length. One neglect of a few days duration is really worse for the fleece than comparatively poor feeding, if it is only adhered to with regularity. Poor feeding and general care, result in a gradually diminished growth and weight of fleece, but yet may not affect the health, while irregular feed- ing affects the health and ruins the flock completely. The supply of water is of the greatest importance. A living spring or a clear flowing stream with dry gravelly banks is the best source of supply. Wells are better than ponds or pools. Stagnant water is exceedingly objectionable. Hard water is better than soft, and water containing much saline or other mineral matter, is a valuable help to the pasture as furnishing many neces- sary substances. When water is exposed to the atmosphere it deposits the greater part of any mineral matter it may contain, and becomes soft. It is then rendered of less value for stock pur- poses. There are some waters that contain potash, lime, soda, magnesia, iron, and sulphur in combination with oxygen, carbonic acid, and chlorine to the amount of 15 to 20 grains per gallon, and such water is a source of nourishment to sheep. Pond or marsh water is highly injurious, as is also running water in which aquatic plants are found. It is from drinking such water, as much as from pasturing on un drained soils, that the liver flukes, parasites always accompanying the disease termed the rot, gain access to the stom- ach and intestines of the sheep. A deficiency in the necessary mineral matters may be obviated by giving the sheep stated sup- plies of a mixture of common salt, sulphur, saltpeter, sulphate of magnesia, (epsom salts), phosphate of lime, bone-dust, or fine bone, with a small portion of sulphate of iron, (copperas). A small tea- spoonful of this mixture given once a week to each sheep will help greatly to a healthful condition, and resist the tendency to disease caused by inferior pasture or soft water. The study of the plants 22 THE SHEPHERD'S MANUAL. suitable for a pasture, the character of soils, and the water, should be part of the education of every shepherd. The exposure of the pasture is another important consideration. Long continued cold winds are productive of great discomfort and sickness, and often cause serious loss amongst the flock. On the sea coast, exposure to the moist sea breezes injures the quality of the wool, and renders it harsh and deficient in quantity. Of two adjoining flocks upon opposite sides of a hill facing north and south, the sheep exposed to the north winds will be several pounds less in weight, and their wool will be whiter, harsher, more uneven, and less healthy looking, than those of the flock upon the south side. This experience is very common. The lambs will also be less thrifty. Of this, many notable cases occur every season where sheep and lambs are pastured and fed for the markets. The small size of sheep raised upon mountain pastures is a case in point. Where the pasture is circumscribed or poor, it may be supple- mented by sowed green crops to be fed on the ground, or cut and fed in racks upon the pasture, or cut and carried to yards and fed there at night in racks. Of these, rye, clover, mustard, rape, tares, and oats and peas mixed, furnish an abundant supply. Rye is sown early in the fall for winter and early spring feeding. For this purpose it should be sown thickly, three bushels per acre being a fair allowance upon fairly good soil, early in August up to the middle of September. The sheep may be turned upon the crop in December, and at intervals as may be found proper, up to April, when it may be plowed down for a spring crop. Upon light lands, where the winters admit of it, as in some of the middle and southern states, this may be made an excellent means of im- proving the soil ; some additional feed, as bran, pea-meal, corn, or cotton-seed-meal, (freed from the hull which is indigestible and injurious), will much assist in this improvement of the soil as well as in bettering the condition of the sheep. After rye, clover sown the previous spring, but not pastured, will come in turn. This will furnish pasture through the summer if kept well stocked down, and a choice portion should be fenced off for the lambs. By changing from one part of the field to an- other, as one portion is eaten down, the new growth will be tender and fresh. After June a part of the clover will run to seed, and when the field is plowed in August or September, the seed will help to re-sow the ground, which may then be sown to wheat or rye. This makes an excellent preparation for these crops on lands of a somewhat light character. White Mustard, (Sinapis alba), may be sown in May or June for FODDER CROPS. 23 feeding in August and until rye is ready. It is difficult to eradi- cate from the soil when it once becomes a weed and has been allowed to take possession. But a careful farmer will have no trouble if he manages the crop so as to prevent the seed being shed. When sown in August, mustard affords valuable feed dur- ing the winter, and although the ground may be covered with several inches of snow, the sheep will scrape off the covering and get at it. In this way a plot of mustard may furnish a green bite all the winter where the snow fall is light. In the spring it should be plowed down early and not allowed to blossom, and a spring crop taken so that the ground is plowed again in the fall. Treated thus, the plant cannot ripen and shed its seeds and become trouble- some. Mustard has a pungent flavor, and contains a large propor- tion of sulphur ; it is on this account a healthful fodder for sheep, and is very much relished by them. It belongs to the botanical order of Cruciferce.to which the cabbage, rape, and turnip, belong; a family of plants rich in sulphur, lime, phosphoric acid, and other mineral matter demanded for the sustenance of sheep. Two pecks of mustard seed per acre are sown, and for a heavy crop of fodder rich soil is required. Rape, a variety of Brassica campestris, is a very hardy plant, and produces a heavy burden of fodder which is readily eaten by sheep. It is very similar in habit to mustard, and should be fed off in the fall and winter or early in spring. Two pecks of seed are required for an acre. For fall feed it should be sown in July or early in August. Both mustard and rape succeed very well in the north- ern, western, and middle states, and would thrive equally well in most of the southern states if sown somewhat later and fed off during the winter. These plants when sown late ripen their seed early in the second year. Turnips are a very frequent fodder crop in those parts of Eng- land where sheep are largely raised, but the practice of allowing them to be fed off from the ground is fast becoming obsolete, and the plan of taking up the crop and cutting and feeding the roots in troughs upon the fields or in yards is substituted in its place. But the English climate is excessively moist, and rain falls two days out of three on the average. It is for this reason, and the in- jurious effect upon the sheep of the exposure upon muddy fields to cold wintry rains, that the practice is falling into disuse. In parts of the United States we have every advantage for making use of so cheap and convenient a plan of feeding sheep upon these root crops that are not injured by moderate frosts. Where the fall of snow is light and soon melts away, as in Virginia, Ten- 24 THE SHEPHERD'S MANUAL. nessee, Missouri, and the states south of these, this system of win- ter feeding has been practiced for many years by the better class of farmers with success. Mr. C. W. Howard, of Georgia, a highly trustworthy gentleman, a farmer and a frequent writer upon agricultural topics, and who has given much attention to the culture of fodder crops, communicated some time ago to the Rural Carolinian the following directions and facts in regard to the cul- ture of turnips for sheep feeding in the open field in the south : " Take a field, plow it deeply with a two-horse plow, subsoil if possible, harrow thoroughly and roll. Lay off the land in rows two-and-a-half feet apart, with a wide and deep furrow. If there be not stable manure, apply three to five hundred pounds of Am- moniated Superphosphate of Lime ; the addition of some potash would be useful ; throw the dirt back with two furrows, and level the ridge with a board. Use the Weathersfield drill, or some other, costing about nine dollars. Sow with it two pounds of seed to the acre. The "Weathersfield drill opens the furrow, drops the seed, covers, and then rolls it by one and the same process. When the plants have formed the third leaf, which is rough, thin them out with the hoe and hand to about eight inches apart, give them a good plowing with a narrow scooter, and the cultivation is completed. The cultivation of an acre of turnips will cost as follows : Plowing ..$ 2 00 Harrowing 50 Boiling 50 Seed.. 100 Sowing: 25 Hoeing and Thinning 2 00 Plowing 1 00 Fertilizer 1000 $17 25 " The result will vary according to the soil, the season, and the cultivation. Five hundred bushels is a poor crop. One thousand bushels is a good crop. Fifteen hundred bushels is an extraordi- nary crop. This number of bushels, (1,550), was made last year by Dr. Lavender, of Pike County, Ga. That gentleman took the premium at the last Georgia State Fair. His statements deserve implicit reliance. They were made under oath. His process of obtaining this remarkable yield was as follows : " * The soil was a sandy loam. Turned over a heavy clover sod in June with a Dixie plow ; harrowed twice with a Nishwitz har- row on the 21st of August ; ran twice in the furrow, deposited in the bottom of the furrow 3,600 pounds of stable manure, com- FOLDING OK TUBNIPS. 25 pounded with 100 pounds of the Stono Phosphate ; let it stand six weeks, then applied as above stated. Cultivated with a cultivator by horse power — no hoeing ; left about six plants to the yard ; had only one rain on them after plowing, and that a light shower. Sowed two pounds of seed to the acre ; planted by hand through a guano bugle, and then rolled.' "What does it cost to raise a' bushel of turnips? If we make 500 bushels to the acre, the cost will be about four cents per bushel ; if 1,000, the cost will be about two cents per bushel. This does not include gathering, storing, and marketing, because the use that it is proposed to make of the turnips involves none of these expenses. " What use, then, is to be made of the crop ? Feed them off on the land with sheep, the process ordinarily known as folding. For this purpose a portable fence is necessary. (These are de- scribed hereafter). " The fold should not include more turnips than the sheep will eat off clean in twenty-four, or, at the utmost, forty-eight hours. If it be larger, the turnips will be wasted. Sheep not accustomed to turnips, may at first refuse to eat them. But let them get quite hungry, and then sprinkle some salt upon the turnips. After they once get a taste of them the only difficulty will be to get enough of them. One thousand sheep will consume an acre of' turnips in twenty-four hours ; one hundred in ten days and nights. With these data, the size of the pen can be graduated. One-tenth of an acre should be the size of the fold or pen per one hundred sheep. One acre of turnips will support one hundred sheep for ten days, three acres one month, nine acres three months. This is not the- ory, but the result of actual experiment. The enemy of the turnip is the fly. There are two means of preventing the ravages of this troublesome insect. One is very thick seeding, the other is dust- ing the young plants as soon as they are above ground, with un- leached ashes, or air-slacked lime. After they reach the rough leaf there is no further danger from this source. The thinning should take place as soon as the rough leaf is formed. If this thinning is delayed, the crop will be seriously injured." For the northern states the culture of the turnip, ruta-baga, su- gar beet, mangel, and cabbage, is as follows: the preparation of the ground being alike for all, the time of sowing alone being differ- ent. Sugar beets and mangels are sown from April to June, the early sown crop being invariably the heaviest. Ruta-bagas are sown June 15th to July 1st. Cabbage for late crop is sown in seed beds in June to be transplanted in July. Yellow Aberdeen 2 26 THE SHEPHERD'S MANUAL. turnips are sown in July, and white turnips in July or August. The soil is prepared by previous plowing and manuring, and made fine and mellow ; the seed is sown in drills 30 inches apart, and thinned out to 12 to 18 inches apart in the rows. A crop of roots grown 18 inches apart, each root weighing 6 Ibs. , will yield 34 tons, or 1,100 bushels to the acre. For beets or mangels, 4 Ibs. of seed per acre is required if sown with a drill ; of ruta-bagas and tur- nips 2 Ibs. of seed is sown. The best beet is Lane's Improved Sugar Beet ; the best mangel, the Long Red ; the best ruta-baga, the Purple-top Swede ; the Aberdeen turnip is better than the white, and nearly as good as the ruta-baga ; the white turnip has the ad- Fig. 1.— PIT FOB BOOTS. Fig. 2. — BOOT-CUTTEB. vantage that it can be sown late and follow an oat, barley, or rye crop. The harvesting is done by cutting off the tops with a sharp FEEDING ROOTS. ot hoe and plowing a furrow on one side of the row of roots, when they may be pulled from the ground with the hoe or by drawing a dull harrow over the field. The crop is saved by keeping the roots in cellars or pits. Pits are simply conical heaps covered with straw and earth sufficient to keep out the frost, a foot of straw and a few inches of earth being sufficient protection, (see fig. 1). Roots should be sliced or pulped when fed, as they are more readily eaten, and there is no dan- ger of the sheep choking by swallow- ing too large pieces. A simple cutting ma- chine is shown in fig. 2. It consists of a wooden wheel fur- nished with long knives set at an angle similar to the irons in a plane, which cut the roots into thin slices. Fig. 3 is a pulper in which, in- stead of knives, there are 144 sharp chisel Fi£- 3.— BOOT PULPER. points made of quarter-inch steel, (see a), by which the roots are torn into shreds and reduced to pulp. When crops are fed upon the ground, a special arrangement of temporary fences is used. These are constructed of hurdles, of which there are several kinds. One of the most readily con- structed hurdles is made of light stakes pointed at the ends and fastened together with bars of split or sawed saplings or laths, such as are shown at fig. 4. These are made in panels about nine feet long, with stakes five and a half feet high. A line of these hurdles is set across the field, enclosing a plot in which the sheep are con- fined, until the crop on the ground is consumed. The shepherd takes a light pointed iron bar with which he makes holes in the ground to receive the pointed lower ends of the stakes, and drives them down firmly by striking the tops with a wooden mallet. As the crop is eaten, the line of hurdles is moved along the field until the whole is consumed. Much economy in labor of setting the hurdles may be exercised by laying out the plots in a certain man- ner. For instance, if a square field of ten acres is to be fed off, the THE SHEPHERD'S MANUAL. plan shown in fig. 5 will be found very convenient. The distance across the field is 220 yards. This is the least length of hurdles that can be used. But if the field is divided off into strips across, the whole of the hurdles must be moved each time, and if the field Fig. 4. — HURDLE. is divided into eight strips, there will be seven removals of every hurdle, or the whole length of netting. In the plan here shown, only half this work is necessary, and a field may be divided into eight sections by moving half the hurdles seven times. For in- stance, plot 1 is fed by placing the ^ hurdles from a to b, and from c to d. Plot number 2 is fed by moving the line from e, d to b, e. The next setting of the hurdles is from e to/, the next from b to g, the next from h to i, the next from b to k, the next, and last, from I to m. There will be eight settings of 110 yards each, instead of seven of 220 yards each, which would be necessary should the field be fed off in the usual manner of strips across it. In place of these hurdles, netting of cocoa-nut fiber or hempen cord is often used. This is supported by stakes driven into the ground and hooks, (see fig. 6). Netting of this kind is made in f.3 e 1 i f 2 f 3 $ 6 i i 7 TO * 8 Fig. 5.— PLAN FOB SETTING HTTRDLES. PORTABLE- FENCES. England in lengths of 100 yards, and widths of 4 feet, at about $9 the 100 yards. At this price it could be imported with profit, and probably cheaper than it could be manufactured here. Another form of hurdles not quite so portable, but more easily moved and set is illustrated at fig. 7. They are 12 feet long, and are made of a stout pole bored with two series of holes 12 inches apart. Stakes six feet long are put into these, holes, so that they project from them three feet on each side of the pole. One series of holes is bored in a direction at right angles to that of the other, and when the stakes are all pro- perly placed, they form a hurdle the end of which looks like the letter X. The engraving shows how these hurdles are made and the method of using them. A row is placed across the field. A strip of ten feet wide is set off upon which the sheep feed. They eat up all the herbage upon this strip and that which they can reach by putting their heads through the hurdles. The hurdles are then turned over, exposing another strip of forage. When this is fed off the hurdles are again turned over, and so on. The chevaux-de-frise presented by the hurdles prevents any trespassing upon the other side of them, and by using two rows the sheep are kept in the narrow strip between them. Their droppings are therefore very evenly spread over the field, and it is very richly fertilized by them. At night the sheep are taken off, and when the field has been fed over, they are brought back again to the starting point and commence once more to eat their way along. When the crop is cut and fed to the sheep, a somewhat different arrangement is made. This may be made a valuable means of improving land. A badly run-down field in- fested with weeds, may be cleared of rubbish, fertilized, and Fig. 6. — SHEEP NETTING. 30 THE SHEPHERD'S MANUAL. PENNING SHEEP IN THE FIELD. 31 brought into grass or clover by judicious management in this way. Portions of such a field may be set off with hurdles as before de- scribed, a rough shed erected in which the sheep may be secured at night, and in which an ample supply of bedding or diy earth, or other absorbent is placed beneath them, and here the crop grown upon another part of the farm, aided by purchased food, if such be available, is fed in portable troughs or racks. A very convenient rack is the one shown in fig. 8. This is extremely portable, and may be moved from one part of the field to another with great ease. Where sheep are permanently kept, and fixed arrangements are made for the flock, it is frequently found con- venient to provide a permanent and safe shed, in a central position, in which they may be confined at night, and from which they can be turned into different fields or portions of the farm. A shed that has been found very convenient in use is shown at fig. 9. It is built at the center of four fields, and has doors opening into each of them, and is so arranged that it may be entirely closed from all but the one which may be in use at the time. For the protection of the sheep at night, small paddocks may be fenced in around this shed, and safety from dogs secured by the use of dog guards. These consist of wires made to run above the fence or at right angles with the top of it, as shown at figures 10 and 11. The separation of the flock into parts consisting of ewes and lambs, weaned lambs and weaklings, and rams and wethers, is very necessary. Ewes and nursing lambs should be provided with the best and tenderest pastures; the weaned lambs and weak sheep should have a place where they can be furnished with some extra feed without interference from stronger neighbors, and rams and wethers may do well enough on the coarser herbage. A frequent change of pasture is very advantageous for the flock. Sheep naturally love change, and after they have wandered over a THE SHEPHERD'S MAKITAL. field will become restless, and try to escape. The best method of keeping them contented and quiet, is to change their pasture as soon as they are observed to wander about restlessly. They are Fig. 9,— SHEEP SHED. then losing flesh. To restrict sheep to one kind of food for a period of more than thirty days, has been found to seriously im- pair their health. " Fresh fields and pastures new " are therefore necessary to their welfare, and their health cannot be maintained I.! • Fig. 10.— DOG GUARD. . 11.— DOG GUARD. unless this peculiarity is recognized and accommodated. It is better to divide fields into paddocks where small flocks are kept, EWES AND LAMBS. 33 and where the pastures are extensive, to reduce the size and in- crease the number of the fields. Where the pasture is an open, unfenced tract, the flock should be driven some distance to a new locality every month. The attention of the shepherd during the summer season will be constantly exercised in seeing that every portion of the flock re- ceives a proper share of the pasture, that the pasture is not over- stocked ; that proper shelter is provided from midday heats ; that failure in pasture is immediately remedied by a supply of fresh green fodder or extra food, such as wheat-bran, oil-cake-meal, or corn-meal ; that pure water is supplied at least twice a day; that a certain portion of salt, or a mixture of salt and sulphur is pro- vided and given regularly ; that on the first symptom of indispo- sition, affected sheep are removed from the flock to some place where they may receive proper care and medicine; that the attacks of flies are warded off by proper preventives ; that para- sitic enemies are destroyed, and hi short hi caring in every possi- ble way for the welfare of his charge, watching closely for the most minute evidence of the first symptom of trouble that may occur, always remembering that "an ounce of prevention is worth a pound of cure." To this end he should study closely the habits of his sheep in health, make himself thoroughly acquainted with the symptoms of disease and the habits and methods of at- tacks of those living enemies which trouble the flock, and be pre- pared by adequate and exact knowledge of the proper preventives and remedies, to apply them instantly, correctly, and effectively. CHAPTEE III. MANAGEMENT OF EWES AND LAMBS. In the management of sheep, how to procure the most profit from the flock is the greatest consideration. It is not exactly how to increase the flock most rapidly, nor to produce the heaviest carcasses or fleeces, but to produce such animals as will return the most money for the expenditure and labor involved. In some lo- calities the sale of an early lamb will bring in more money than that of the mother with its fleece. Where there is a market for lambs, it is evidently the most profitable to keep such sheep, 34 THE SHEPHERD'S MANUAL. and to keep them in such a way as will produce the highest priced lambs. Where mutton is the most profitable, there a different management must be adopted, and frequently a different breed of sheep must be kept. Where wool only is the object, still another different course will be chosen. Whichever end is to be gained, the care of the breeding ewes and the lambs will be a subject of much solicitude. But what would be a proper course in one case •would not be at all proper in another. A few general principles are involved in the management of ewes and lambs, which will first be explained, after which the special management proper to be adopted for each special case will be considered. The period of gestation of the ewe is 150 to 153 days. Five months in round numbers may be taken as the period during which the ewe carries a lamb. The coupling of the ewes and rams should be so timed, that the lambs may be dropped at the most desirable season. It will be found a great convenience to mark the ranis and ewes, or such of them as may be selected to breed stock animals from. Where a small flock only is kept, or where special care is given to the im- provement of the breed, every sheep should be marked by a number, that the time of its coup- ling may be noted, and the date of the expected birth of the lamb be known. The best method of marking is by means of metallic ear marks, (fig. 12), made by C. H. Dana, of West Lebanon, N. H., inserted in the ear in different ways, to distinguish the sexes easily. The method of keeping these records may be as fol- lows : A book is provided which is ruled with six columns. At the head of these columns are written the number of the ewe, that of the ram, the date of service, the expected time of the lamb's ap- pearance, the date when it is actually dropped, and any remarks worthy of note. The following diagram exhibits this clearly : 12. — METALLIC EAR-MARKS. No. of Ewe.]No. of Bam. 137 ~~4 When served, To Lamb. Lambed. \Remarks. Sept. 26, '75 Feb.26, '76 Feb.28,'76] Twins. Under the head of remarks should be written anything that may be desirable to remember in regard to the character of the produce of the animals coupled. A ewe that produces a fine, large, active CAKE OF THE RAM. 35 lamb, that is a good nurse, and that rears a profitable market lamb, or that rears twins successfully, is a valuable animal to re- tain in the flock so long as she remains productive. Such ewes have been kept until 10 or 12, or even 16 years old, and to be able to identify a ewe of this kind is very necessary when the greatest profit is the object sought, and more especially in those cases when the special business is to rear market lambs or increase the flock rapidly. No more than 30 ewes should be apportioned to one ram in any season, unless he be a full grown one and in vigorous health, and it would be well to observe the rules laid down in a succeeding chapter especially devoted to breeding, for the man- agement of the ram at this season. If the ram is equal to the work, 50 ewes may be given to him, but it is better to err on the safe side in this matter, as overwork simply means barren ewes and loss of lambs. At the breeding season the ram should be smeared upon the brisket every day with a mixture of raw linseed oil and red ocher, so that he will leave a mark upon each ewe that may be served. As the ewes are served they are to be drafted from the flock and placed in a field or yard by themselves. Two rams should not be kept together in a small breeding flock, as quarreling and fighting are certain to result and great damage may occur. If two rams are necessary, each may be used on alternate days. Wethers are a nuisance in a flock of ewes at this season, disturbing them and keeping them and themselves from feeding. A plan followed with advantage where the flock consists of heavy bodied sheep, and where the necessary attention can be given, is to keep the ram in a yard or paddock by himself, out of sight of the ewes, and to allow a wether to run with them. As each ewe comes in season, the wether singles her out and keeps company with her. On the return of the flock from the pasture at night, the ewe or ewes in season are turned in to the ram until they are served, when they may be removed at once, or left with him until the morning. In the morning, if any ewes have come into heat during the night, they may be served before the flock is turned into the pasture. This is continued until it is known that 'all the ewes are in lamb. By this method a ram may be made to serve double the number of ewes that he would if allowed indis- criminate access to them, and exhaust himself in useless and need- less repeated exertions. As soon as the ewes have been served, the time of each is entered in the record as previously described. They are carefully pre- served from all worry by dogs and needless driving or handling. Peace and quietness at this season will tend to the production of 36 THE SHEPHEED9S MANUAL. quiet and docile lambs. The shepherd should make himself very familiar with them, and by giving salt or meal in the hand, or a small dish, reduce them to a condition of perfect docility. Any ewes that have either refused Ae ram or have failed to breed, should be dosed with two ounces of epsom salts and be stinted in their feed for a few days to reduce their condition. This will generally be effective in bringing them into season. Good fair condition is better than an excess of fat, but ewes in poor condi- tion cannot be expected to produce other than poor, weak lambs ; neither will an excessively fat ewe produce a strong lamb. Some extra food will now be needed by the ewes, and should be given at first in small quantities. Bran, crushed malt, and crushed oats and corn mixed, are the best kinds of food. Oil-cake, either of cotton-seed or linseed, unless used with great caution, is not always a healthful food for ewes in lamb. Any food that actively affects the bowels, either way, is to be avoided. Half a pint a day may be given of the first mentioned foods, and a change from one to an- other may be frequently made. So long as pasture is to be had, this allowance will be sufficient. When the winter feeding com- mences, the ration of grain should be gradually increased until, at the period when lambing time approaches, a pint daily is given. Cold watery food is highly dangerous at this time, and roots should not be given in large quantities, nor at all unless pulped and mixed with cut hay and the grain. Turnips or other roots that have been highly manured with superphosphate of lime has been said by several experienced English breeders to be pro- ductive Of abortion. Water should be given in small and frequent quantities. It is best to have running water or water from a well always at hand for the ewes. If the ewes have not heretofore been kept apart from the rest of the flock, they should now be sepa- rated. The general treatment of the ewes up to this time should be such as will keep them free from all excitement, and in good, healthful condition. The record should now be consulted, and as the ewes near their time they should be removed into a part of the stables or sheep barn, where each one can have a small pen to herself. These pens should be made so that light can be shut out if desired. Here they are permitted to drop their lambs in perfect quiet ; by this means few ewes will disown their lambs, and no lambs will be lost by creeping into feed racks or out of the way places. The pens should not be larger than 5x4 feet. As soon as the lamb is dropped and the ewe has owned and licked it, and the lamb has once sucked, all danger, except from gross careless- ness, is passed. The ewe will be greatly helped by a drink of CARE OF THE EWK slightly warm, thin oat-meal gruel well salted. The lamb will be benefited by a teaspoonfui of castor oil, given in new rnilk, if the first evacuations do not pass away freely. These are apt to be very glutinous and sticky, and by adhering to the wool to close the bowel completely unless removed. Warm water should be used to soften and remove these accumulations. The anus and surrounding wool should then be smeared with pure castor oil. If the lamb is not sufficiently strong to reach the teats and suck, it should be assisted once or twice. Any locks of wool upon the ewe's udder, that may be in the way, should be clipped. If the lamb is scoured, a teaspoonfui of a mixture of one pint of peppermint water and one ounce of prepared chalk should be given every three hours, until it is relieved. When the ewe refuses to own the lamb, she may be confined between two small hurdles, as shown in fig. 13. Two light stakes are driven in the ground close to- gether to confine the ewe's head and keep her from butting the lamb. If she is disposed to lie down, as some obstinate ones will do, a light pole is passed through the hurdles resting upon the lower bar beneath her belly. Thus confined during the day, she is helpless, and if the lamb is lively, it will manage to get its supply of food. The ewe should be released at night. One day's confinement is often sufficient to bring an obstinate ewe to reason. A twin lamb, or one deprived of its dam, that may need to be reared by hand, may easily be fed upon cows' milk. A fresh cow's milk is the best fitted for this purpose. Ewe's milk is richer in solid matter than that of the cow, and the addition of a tea- spoonful of white refined sugar to the pint of cow's milk will make it more palatable to the lamb. At first not more than a Fig. 13.— HURDLES FOR EWE. 38 THE SHEPHERD'S MAHUAL. quarter of a pint of milk should be given at once. The milk should be freshly drawn from the cow, and warmed up to 100 degrees before it is fed. A convenient method of feeding milk to a lamb is to use a small tin can with a long spout, such as is used for oil. An air-hole is punched in the cover or cork and a piece of sponge covered with a cloth is tied upon the end of the spout. The flow is thus made easy and equal, and the lamb sucks in a natural man- ner. The accompanying illustration, (fig. 14), shows the method. A very short time is sufficient to familiarize the lamb with this kind of foster mother. To encourage the flow of milk in the ewe Fig. 14. — FEEDING LAMBS. and the corresponding growth of the lambs, the food of the ewes should be of the best character. Clover hay, bran, and crushed oats, with some pea-meal, are the most preferable foods, produc- ing a rich milk in abundance. The ewes must not be allowed to fall off in condition, or the lambs will fail. During mild weather, sugar beets may be given in moderate quantity with advantage, but mangels or Swede turnips, (ruta-bagas), should be avoided as too watery and deficient in nutriment, and productive of scours in the lamb. In cold weather roots are apt to reduce the tempera- ture of the animal too suddenly if given in any but small quanti- ties, and consequently decrease the flow of milk. Pea straw is a favorite and nutritious food for sheep, but it will be found profit- DOCKING AND CASTRATING LAMBS. 39 able to give only the very best at hand to nursing ewes. The after growth and condition of the lambs will greatly depend upon the maintenance of a thrifty and continuous growth during the first three months of their existence. At the age of a week the operations of docking and castrating the male lambs, may be safely performed. At this age the young animal suffers but little, there is no loss of blood, and the wounds heal by the first intention. The rough and ready method of clip- ping off the tail an inch from the rump, first drawing the skin upwards, and of clipping off the scrotum and testicles altogether with a pair of sharp sheep-shears, will be found perfectly safe if done before the lamb is two weeks old. The nerves being very slightly sensitive at this time, the painful, and when later per- formed, dangerous operation of emasculation is only slightly felt, and within an hour a lamb bereft of tail and generative organs will frequently be seen skipping playfully in the sunshine. To dock an older lamb is a more troublesome operation. To do this with facility, a block of wood about a foot high, a sharp, broad chisel, and a wooden mallet, are required. The operator stoops with bended knees, the block being in front of him, takes the lamb with its head between his knees and its tail in his left hand, hold- ing the chisel in his right hand. Backing the lamb's rump up close to the block, he lays the tail upon it, and drawing back the skin of the tail up to the rump, holds the chisel lightly upon the tail close to and below the fingers of the left hand. When all is ready he directs an assistant to strike the chisel smartly with the mallet, by which the tail is instantly severed about two inches from the root. A pinch of powdered bluestone (sulphate of copper), is placed on the wound, and the lamb is re- leased. To castrate an old lamb with safety, the scrotum should be opened by a long free incision with a sharp knife at the lower point, the animal being at the tune turned upon its back and secured in that position. The scrotum should be held in the hand tightly enough to keep the skin tense. The cut should be made only through the skin and coats of the testicle, and not into the gland, by which a great deal of pain is spared to the animal. The gland will escape from the scrotum at once if the opening is made large enough. It may be taken in the left hand and the cord and vessels scraped apart, not cut, by which bleeding is prevented and healing made m ore certain and rapid". The opening being made at the bottom of the scrotum, allows the blood and any pus that forms hi the wound;to escape freely. It might probably be bene- ficial to insert a small plug of tow in the wound, projecting out of 40 THE SHEPHERD'S MANUAL. it a short distance to prevent the edges from healing until the in- flammation has subsided. This method of operation is a safe one, and if it is neatly done, the losses need not be one per cent, while frequently three lambs out of five may be lost by any other method. While the lambs are still with the ewes, and although the ewes may be well fed with a special view to the thrif tiness of the lambs, yet a supply of additional food for the latter will be of great ad- vantage to them. To furnish a young animal with all the food that it can digest, and that of the choicest character, is to create a sturdy, thrifty, strong constitutioned animal that will be prolific in reproduction and long lived. To advance the maturity of an animal is also to lengthen its life, for it matters not at which part of its productive career we add a year, it certainly, so far as profit is concerned, lives a year longer for us. If a yearling ewe can be made to produce a healthful, strong lamb, or a lamb can be brought by care to maturity for the market at eighteen months in- stead of thirty months, this result is simply equal to a profit of 40 per cent. And feed is the agent by which this profit is secured, of course made available by proper care in selecting the breeding stock. To provide the means whereby the lambs may procure the extra feed needed for their rapid development, many contrivances have been brought into use. Generally these are modifications of the plan of providing a pen or yard adjoining that in which the ewes are kept, with " creep holes " in the fence through which the lambs can gain access to it. In this yard some feed, consisting of oats, rye, and wheat bran ground together very finely, is placed in troughs or boxes, and lightly salted. They will soon find this, and will resort to it several times a day. A very simple and conve- nient " lamb creep " is figured at fig. 15, and has been illustrated and described in an English journal, the Agricultural Gazette. It is very frequently used by English farmers, and is worthy of being adopted by us. It consists of a small double gate or two half gates set at such a distance apart that the lamb can easily force itself through between them. An upright roller on each side of the opening assists the lamb hi getting through the space, and prevents it from rubbing or tearing its wool. The gates are pivoted at top and bottom, so that they will open a little either way ; a wooden spring being fixed so as to keep them closed after the lamb has passed in or out. The lambs pass in or out at will. Creeps of this kind can be made so as to occupy a panel of fence or a gate- way, and of a portable character, so that they can be easily fixed to the fence-post on each side by a wire or withe, and removed WEANING LAMBS. 41 when no longer needed. But, by whatever means it maybe done, the lambs should be supplied with some additional concentrated and nutritious feed. As a gentle laxative in case of constipation, a few ounces of linseed oil-cake-meal will be found sufficient, and far better than physic. Linseed oil, (raw), or castor oil, a tea- spoonful of either at a dose, will be found safe and effective for either constipation or diarrhea, unless of a serious character. As lambs progress towards the period for weaning, the extra Kg. 15. — LAMB CBEEP. food should be gradually increased, unless they can be removed to a good pasture of short, tender grass. In this case even a small allowance at night on their return to the fold will be beneficial. The weaning should be very gradually done. The sudden remov- al of the lambs from their dams is injurious to both. It too ab- ruptly deprives the -lambs of their most easily digested and most agreeable food. It forces them to load the stomach with food for which it is hardly yet prepared, and suddenly arrests their growth 4:2 THE SHEPHERD'S MANUAL. both by a stinting of food and by the nervous irritation conse- quent upon their sudden deprivation. The dams in full flow of milk, thus at once deprived of the means of relief, are subjected to the engorgement of the udder, with the consequent congestion of all the organs connected therewith. This shock is very injuri- ous, and frequently produces inflammatory disorders of the blood or garget. To avoid these ill effects of the sudden change, it is well to remove the lambs to a distant pasture, along with some dry ewes or wethers for company. The novel experience of a fresh pasture will cause them to forget then- dams, and they will utter no complaints nor manifest any uneasiness. At night they should be turned into the fold with the ewes, whose full udders they will speedily relieve. By withdrawing any extra feed hith- erto given to the ewes, somewhat gradually, (in no case is it wise to make a sudden change in the management of sheep), their sup- ply of milk will gradually decrease, and in two weeks the whole of the lambs may be weaned with perfect safety to themselves and the ewes. After having been weaned, the lambs should have the first choice of pasture and the best and tenderest cuttings of the fodder crops. Many farmers have found it advantageous in every way to turn newly weaned lambs into a field of corn in the month of August. The corn is too far grown to be injured, the suckers only will be nibbled by the lambs, and the weeds which grow up after the corn is laid by, will be eaten closely. The lambs also have the benefit of a cool shade, and where such a field can be conveniently applied to this purpose, there are several reasons why it might well be done. The condition of the ewes must not be neglected at this time. The chief danger is in regard to those that are heavy milkers. Such sheep should be closely watched, and the milk drawn by hand from those whose udders are not emptied by the lambs. The first approach to hardness or heat in the udder should be remedied by an immediate dose of an ounce of epsom salts dis- solved in water, and mixed with a teaspoonful of ground ginger. The next two days 20 grams of saltpeter should be given each morning and evening, to increase the action of the kidneys. These remedies will generally relieve the udder, and will tend to greatly reduce the secretion of milk. If hay is given in place of grass, and the ewe confined in a cool darkened pen, the drying up of the milk will be hastened. As the improvement of the flock can be better made from within than by giving the sole attention to bringing new blood from SELECTION OF LAMBS FOB BREEDING. 43 without, it will be very important to select the best lambs, both of rams and ewes, for breeders. The selection should be made chiefly in reference to the purposes for which the flock is kept, and strength of constitution, rapidity of growth, size, tendency to fat ; fineness, length or quality of wool, and prolificness and cer- tainty of breeding, in the parents as well as, so far as can be judged of, in the lambs themselves, should be made the tests by which the selection is determined. If the production of early lambs for market is the object, the produce of those ewes which bring single lambs of large size and quick growth will be chosen to increase the flock ; if the production of mutton sheep, then those lambs from ewes which drop twins, and are good nurses, ought to be kept ; and if wool of any particular kind is desired, then the selection should be made chiefly in reference to that. On no ac- count should weakly lambs, or those ewes which are poor nurses, or fail to breed, or which exhibit tenderness of constitution, or are wanderers, or of uneasy, restless dispositions, be retained ; but such unprofitable animals should be closely weeded out and fat- tened for sale or for slaughter. The choice of ram lambs is of chief importance, for the influence of the ram runs through the flock, while that of the ewe is confined to her produce alone. To select a lamb for a stock ram is a matter requiring a knowledge of the principles of breeding, and some tact and experience. The lat- ter qualifications cannot be acquired from books, but must be gained by practice ; nevertheless, much as to the selection of lambs may be learned from a careful consideration of what will be found in the succeeding chapter, which is specially devoted in part to this important branch of the shepherd's knowledge. The proper age for breeding differs with the class of sheep bred. The Merino is not mature enough for breeding until fully two or three years old. Other breeds which mature more quickly are ripe for breeding as yearlings, but there is nothing gained by suf- fering any sheep less than a year old to reproduce. A young ram in its second year may be allowed to serve a few ewes, if he is vigorous and well grown. A ram at two years may serve 30 ewes in a season, and after that from 50 to 60 or 70, according to the manner hi which he is kept, and if he is restricted to no more than one or two services of each ewe. The strength and vigor of the lamb certainly depends on that of the ram by which it is sired, as well as on the condition and character of the ewe. Ewe lambs of less than a year old. should be kept in a separate flock by them- selves where they may not be disturbed by the rams. The second year they are capable of breeding, and if they have been well 44 THE SHEPHERD'S MANUAL. cared for, will produce as large lambs and as many twins as older sheep. The young ewes having their first lambs are apt to be ner- vous, and need careful attention at yeaning time ; it is then that the great convenience resulting from having a docile and friendly flock, well acquainted with, and confiding in, their shepherd, is manifest. The young ewes should not be put to the ram until the older ones are served, so that they will not drop their lambs until the spring is well advanced, and the pressure upon the shepherd becomes lighter. As a rule they are poor nurses, and if the season is cold, will lose many lambs. If they are not allowed to have lambs until April or May, so much the better ; it will then be neces- sary to keep them from the ram until November and December. Difficulty in parturition is sometimes experienced with young ewes, and assistance is often needed. This should be given with the utmost gentleness and tenderness. When the presentation is all right and natural, and the fore feet appear, but difficulty occurs in ejecting the head, a very slight and slow drawing upon the feet may help the ewe in expelling the lamb. Sometimes in her ner- vous struggles the head may be turned backwards, and does not appear when the fore legs have protruded. In this case the lamb should be gently forced backwards, and the hand or fingers, well oiled with linseed oil, and the finger nails being closely pared, are inserted, and the head gently brought into position, when it will be expelled without further trouble. For more difficult and ab- normal presentations, the services of an experienced shepherd will be needed, but such cases are very rare, and will very seldom oc- cur if the flock has been carefully attended to, and has not been overdriven, or worried by dogs, or knocked about by horned cattle. When a ewe loses her lamb it is best to make her adopt one of another ewe's twins. This may be done by rubbing the skin of the live lamb with the dead one, removing the dead one and shut- ting up the ewe and live lamb together in a dark pen. When a lamb loses her dam, it may be given to a ewe that has lost her lamb, or from which her lamb has been taken, or with care it may be brought up by hand without difficulty. In every considerable flock it will pay to have a fresh cow on hand at the lambing sea- son, to fill the place of foster mother to disowned or abandoned lambs, or to assist those whose dams for any reason are short of milk. The question as to when a lamb becomes a sheep, although of no practical utility, has sometimes been of sufficient importance to require a decisive reply. A legal decision was given in an English court not long since, which is probably as reasonable as PKEVENTION OF DISEASE. 45 we may expect, and may be accepted as being authoritative. The question arose out of the killing of some sheep on a railroad by a passing train, and it was denied that the complaint was properly made, the animals being lambs, and not sheep. The judge decided that lambs ceased to be lambs, and became sheep as soon as they had acquired their first pair of permanent teeth. This change of teeth generally occurs when the lamb is a year old. At this period the middle pair of the first teeth drop out, and a pair of the per- manent incisors appear. At one year and nine months, two more of the first teeth are dropped and two more permanent incisors, one on each side of the former pair, appear. Nine months later, two more permanent incisors appear in a similar manner, and nine months later still, another pair are produced, so that at three years and a quarter the sheep has eight permanent incisors or nippers, and is then called a full-mouthed or perfect sheep. These periods of dentition are irregular, and in some of the early maturing breeds, the first pair of permanent teeth will appear before the end of the first year, and at 16 months, four permanent incisors may be found. The earlier maturity of the high bred and high fed races of sheep, such as the Leicester, Cotswold and Shrop- shire, sometimes amounts to a gain over the common breeds of nearly a year in time, and full-mouthed sheep of no more than two years and a half old are not uncommonly met with. The diseases to which lambs are subject are but few, and those are mainly the result of carelessness in their management. The lamb, which appears so delicate and tender an animal, is really hardy, and resists much ill treatment, else with so little consider- ation as they usually receive, the race would soon become almost extinct. Damp and cold are especially to be guarded against in the spring, and filthy yards at all seasons. With clean pens and dry, clean bedding, they will resist the severe dry colds of a north- ern January, and thrive and grow while snow storms rage, if only well sheltered. Sunshine has a remarkable effect upon lambs, and the warmth of the sun will often revive and strengthen a weak lamb that appears past relief. Extremes of damp and im- pure air in close pens, and bad drinking water, will produce diar- rhea and paralysis, and these are the chiefly fatal disorders to which they are subject. Constipation is produced by want of proper laxative food, and permitting them to feed on dry, withered herbage that has lost its nutritive qualities beneath the storms of a winter. If the directions as to their treatment heretofore given, are followed, there will rarely be any need of remedial measures, and prevention will be found better than any amount of cure. If, 46 THE SHEPHERD'S MANUAL. notwithstanding all possible care, some weakly lambs are found to require treatment, the simple purgatives already mentioned in this chapter, viz : a teaspoonful of castor or raw linseed oil will be found effective, after two or three doses, in removing the trouble- some matter from their intestines, and restoring the bowels to healthful action. If in any case, a stimulant seems to be needed, as when great weakness and prostration are present, the safest is a teaspoonful of gin, given in a little warm water with sugar. A still more gentle stimulant and anodyne, but one very effective in prolonged diarrhea, is prepared by adding to a pint of peppermint water, one ounce of prepared chalk, a teaspoonful each of tinc- ture of opium and of tincture of rhubarb ; it is worthy of the name given to it by shepherds, viz : " lambs cordial," and at the lambing season no shepherd should be without a supply of it. The dose is a teaspoonful for a lamb of a few days old, up to a tablespoonful for one of a month. Exposure to cold rains should be specially guarded against, and if by inadvertence a lamb is found chilled and rigid from such exposure, it may generally be restored by means of a bath of warm water and a teaspoonful of warm sweet- ened gin and water. After the bath the lamb should be gently dried, wrapped in a warm flannel, and placed near a fire or in a wooden box in a gently heated oven of a common stove. Where the flock is large, and the kitchen is not within reach, the shepherd should have the conveniences of a shed and an old cooking-stove in which he can keep a fire sufficient to heat a water bath, and pro- vide a warm bed in the oven for any lamb that may need such attention ; if the flock numbers several hundred head in all, there will seldom be a day in our changeable spring seasons when there will not be one or more patients to be treated. The specific diseases to which lambs are subject will be found treated of at large in Chapter VII. As the season progresses, and shearing time for the ewes has passed, the lambs will be found covered with ticks, unless care has been exercised to free the flock from this tormenting pest. These ticks are wingless, broad, plump, dark red insects, about a quarter of an inch in length, and covered with a very tough and leathery integument. They are known scientifically as Melophagus ovinus, and produce a puparium which is nearly round in shape, red in color, and as large as a radish seed or duck shot. The legs of the tick are short and stout, and it adheres with great tenacity to the wool. By means of a proboscis as long as its head, it pierces the skin and sucks the blood of its victim to such an excess that when numerous, they have been known to almost entirely empty the REMEDY FOR TICKS. 47 veins and deprive a lamb of life. The draft upon the vitality of lambs inf ested with ticks is very great, and sufficient to arrest their growth altogether. To rid the flock of these pests is therefore a necessary labor in the spring or early summer, and if need be, again in the autumn. The easiest remedy is to dip both sheep and lambs, as soon as the sheep are shorn, and again in August or September, in a decoction of tobacco mixed with sulphur. Coarse plug tobacco, or tobacco stems, which are cheaper than the leaves, and equally effective, are steeped in water at a boiling heat, but not boiling, at the rate of four pounds to twenty gallons of water. Fig. 16.— DIPPING SHEEP. One pound of flowers of sulphur is then stirred in the liquid, which is brought to a temperature of 120 degrees, and kept so during the dipping by the addition of fresh hot liquor. During the dipping, the mixture is kept stirred to prevent the sulphur from subsiding. The dip may be conveniently placed in a trough or a tub large enough to allow of the immersion of the sheep or the lamb, which is taken by the feet by two men and plunged into the bath at the temperature mentioned, where it is held for a minute or two until the wool is thoroughly saturated. The animal is then placed in a pen with a raised floor sloping on each side, to a trough in the middle, along which the superabundant liquor escapes into a pail or tub placed to receive it. The method of dipping, (shown at THE SHEPHERD'S MANUAL. figures 16 and 17), is calculated for small flocks, or for a few hun- dred lambs. For larger flocks, a larger tank is provided, 12 feet long, three feet wide, and four feet deep. A fenced platform leads from a pen hi which the sheep are gathered, up to the edge of the dipping tank, and the sheep are taken one by one from the pen, led up the platform, and pushed into the tank in which the dip is sufficiently deep to cover them. As the sheep plunge into the dip, they are seized, and kept beneath it, except the head, which alone is sufiered to emerge above it. If hi their struggles a little of the dip should enter their nostrils, no harm results, but the hot tobacco water is, on the contrary, often beneficial to those sheep which are affected by catarrh or grub in the head, and the violent sneezings which follow may help to free them from these trouble- some parasites which often inhabit the nasal sinuses. The sheep are rapidly passed from hand to hand along the tank un- til they reach the end, where there is a sloping plank upon which they can walk up to another platform. Here they are al- lowed to remain while the excess of dip is squeezed from their wool. From this the liquid drains into tubs, and is carried to the boiler to be re- heated, and then returned to the tank for use again. The cost of dipping a large flock, numbering several thousands, in this man- ner twice in the season is five cents a head, and the improvement in the quality of the wool, which results from the cleansing of the skin from dust, grease, and the accumulated refuse of its secre- tions, and its increase in quantity consequent upon the greater comfort of the sheep and their escape from the persecution of ticks and other parasites, is estimated at 20 cents per head, so that the cost is repaid more than three-fold. The comforting knowl- edge to the humane shepherd that his flock is freed from a most annoying torment, is also something, which, although it does not enter into a pecuniary calculation, and is not measured by dollars and cents, yet is not on that account unworthy of consideration, Fig. 17. — TROUGH FOB DIPPING LAMBS. WINTER MANAGEMENT. 49 There is no greater satisfaction to the owner of a flock, who cares for his sheep, and takes pleasure in their welfare, and in a measure loves the gentle kindly animals, and is interested in managing them so that they may enjoy all the comfort possible for them, than to know that, so far as any efforts of his are concerned, nothing is left undone that can add to their contentment, and that they are spared every discomfort and pain that it is possible to prevent CHAPTER IV. WINTER MANAGEMENT OF SHEEP. The change from green, succulent food, to that of a dry and concentrated character, is one that needs to be cautiously made. As the summer departs and the fall rains occur, succeeded in their turn by the more rigorous storms of whiter, conditions arise which call for a complete change of management on the part of the shep- herd who looks for profit from his flock. It may be a question with some if quality of feed or shelter is the more important con- sideration in the best management of sheep. Certainly abun- dant experience has shown that with the most careful and judicious feeding, sheep, which when well tended are in reality hardier than are generally supposed, have passed safely and thriftily through a winter's storms with no more shelter than that afforded by an open shed; and that they have of their own free will refused the shelter, and have chosen to rest upon the bare snow, at times when the air has been dry and clear. But no case has as yet ever occurred in the experience of any shepherd in which sheep have thrived without ivell selected, proper, and abundant food, and cases are always occurring in which sheep are greatly injured by excessive carefulness in this matter of shelter. To feed well and judiciously, may therefore be regarded as the first duty and interest of the shepherd ; and to shelter the flock only so far as to maintain it in healthful con- dition, avoiding exposure to unusual rigors of heat or storm, will be not exactly a second duty, but one that attaches to this first interest as being intimately associated with it rather than separated from it. Nevertheless, as before a flock can be fed, it ia 3 50 THE SHEPHERD'S MANUAL. necessary to have a store of food and a feeding place, it may be well to consider first the subjects of shelters or barns, feed racks, and facilities for watering. The first requisites for the comfort of sheep in their winter lodging are a dry clean floor, a tight roof, and abundant ventila- tion. The site of a sheep-house should therefore be well drained, and of such a character that it can be kept clean and free from filth. It should, if possible, be on high ground which slopes each way from it, but at any rate it should slope to the south or south- east. The house should be well roofed and provided with rain troughs and spouts to carry the water away from the yard into either a covered drain or a cistern. It should be open at the front, protected only by a projecting roof, and the walls, if of boards, need not be battened over the joints, as the air which will enter Fig. 13.— SHEEP BABN. through these cracks will be no more than will be needed to keep that within fresh and pure. Some more carefully protected shelter must be provided for the use of yeaning ewes and young lambs, in a part of the house or in another building, but until the appear- ance of the lambs is looked for, this warmer shelter will not be needed. The loft over the lower apartment will be used for stor- ing hay or other fodder, and space for this purpose may be econ- omized by having the upper floor only so far above the ground floor as will allow the shepherd a comfortable passage beneath it. A building which is well arranged and convenient is shown in figures 18, 19, 20, and 21. The following description with the illustrations are taken from the American Agriculturist. It con- sists of a barn, shown at fig. 18, about 20 feet wide, 16 feet high BARNS AND SHEDS. 51 from basement to eaves, and as long as desirable. This is intended to store the hay or fodder. The posts, sills, and plates are all 8 inches square, the girts and braces are 4 inches square, the beams 2x10, are placed 16 inches apart, and are cross-bridged with strips, 3 inches wide. The hay is piled inside, so that the feed passage below, over which there are trap- doors, is left uncov- ered. The hay is thrown down through these doors, and falls upon a sloping shelf, which carries it into the feed racks below, (see fig. 19). The basement under the barn is 8 feet high, and is of stone on three sides ; the front is supported by posts 8 inches square, and 8 feet apart. Between each pair of posts a door is hung upon pins, (fig. 20), which fit into grooves in the posts, so that the door may be raised and Fig. ^.-SECTION OF BUILDING. fastened, in such a manner, as to close the upper half of the space between the posts ; or be .held suspended half way, leaving the whole open; or be shut clown and close the lower half; or be removed altogether. By this contrivance at least half the front of the basement must be left open, whether the sheep be shut in or out. The floor of the basement should be slightly sloping from rear to front, so that it will always be dry. Fig. 21 shows the plan of the basement.

Below the feed-rack is the feed-trough for roots or meal. A door shuts off this trough from the sheep at the front, while the feed is being prepared, and when it is ready, the door is raised, and held up to the feed-rack by a strap or a hook. The feed-rack is closely Fig. 21. —GROUND PLAN OP BARN. boarded behind, and this back part, which is in the feed-passage, slopes forward to the front, so as to carry the hay forward to the bottom. The front of the rack is of upright slats, smoothly dressed, two inches wide, and placed three inches apart. The boards of the feed-trough are smoothly dressed and sand-papered, and all the edges are rounded, so that there is nothing by which the wool may be torn or rubbed off from the sheep's necks. It will be seen by this arrangement, that there is no dangerous thing Fig. 22.— SHEEP SHED FOR A SMALL FARM. by which a sheep or a lamb might be hurt, nor a place where it can get into mischief.

Another sheep-house suitable for small farms, that is designed for small flocks, is shown at figure 22. It is altogether open in the front on the ground floor, and is intended to face to the south. This is a very cheap and convenient shed for a small flock ; it has an enclosed yard attached to it. A shelter in- tended for a large flock is shown at figure 23. This building was erected by Mr. George Grant, of Victoria, Kansas, for his flock of 7,000 sheep. The walls are of stone, and the roof of boards. The main structure is 570 feet in length, and the three wings are each of equal length. The width of each of the sheds is 24 feet, and thehight of the walls 10 feet.

A shed of this character is rather costly in its construction, and a small capitalist would find it beyond the limit BARNS AND SHEDS. 55 of his resources. One of a cheaper construction and less perma- nent character, but nevertheless of equal value for shelter so long as it lasts, is shown in figure 24. This shed was built by Mr. Shaw, of Syracuse, Kansas, and was found to answer every pur- pose. It is made of posts set in the ground, which support a single sloping roof that is thatched with coarse hay from the river bot- toms adjacent to his location. The enclosure contains a windmill, watering trough, stack-yard, and feed-racks, and is intended to accommodate a flock of 200 to 300 sheep- The length of the en- closure is 200 feet, and the width 100 feet, making in all 600 feet of shed.

The yard, «, is 100 feet square, divided by a hurdle fence, shown by the dotted lines, into as many portions as may be desired. The entrance is at £, where there is a gate hung upon a post, c, in such a way as to open or close each lalf of the yard. The yard is enclosed on three sides by a shed 10 feet high, with a roof sloping both ways. The ground loor, 7 feet high, is appropriated for sheep pens, and the three feet above for a hay loft. The shed is 12 feet wide, and has a row of separate pens 6 feet wide, upon the north side. On the other sides there are narrow doors for the sheep, seen at Agriculture Pratique, of the 27th of May following, with a portrait of one of these sheep which is reproduced here. The course followed by Mons. Pluchet during the 36 years of his persevering effort is very suggestive and instructive. He commenced in 1839 by coupling his Rambouillet Merino ewes, weighing about 68 pounds when dressed for the butcher at 3 years old, with a pure Leicester ram of moderate size. The effort to produce what he wanted, by one cross only, failed. At first the lambs were too small, and the fleece was too light. Greater suc- cess was made by crossing the half-blood ewes with rams of quarter Leicester blood. The produce, containing three-eighths Leicester, and and five-eighths Merino blood, were much improved, giving a much longer and better fleece than the half or quarter, bloods. After continuing a course of breeding the produce of this cross together, up to 1856, a new type of animal, entirely dif- ferent from its ancestors, resulted. The carcass was much larger than in the Merino, the wool was not so long as that of the Lei- cester, but finer and softer ; the face was free from wool, and the head was square, with large, prominent eyes. The bone was remarkably fine ; the flesh solid, and the ewes were prolific and remarkably good nurses; but neither the carcass nor the fleece were sufiiciently heavy to be profitable. The ewes of this cross were coupled with a pure Leicester ram, and the produce being eleven-sixteenths Leicester, were again crossed with rams of three- eighths Leicester, or of the previous cross. The sheep thus pro- cured were 8|- sixteenths Leicester and 7|-sixteenths Merino, or nearly half bloods. The close in-and-in-breeding of 1his cross gave a race, of sheep that, when fed on the same pastures as the original Merinos, produced exactly the same dead weight of meat of superior quality at 24 months, that the Merinos gave at 36 months, and a fleece weighing 9£ Ibs. in the yolk, which sold at a higher price per pound than the Merino fleece. Under the cir- cumstances in which Mons. Plachet was placed, the result was very profitable, and the new race he originated occupies a place which neither of the original parents was able to fill. Under a system of close breeding, without fresh admixture, the quality and character of this flock are maintained, and the ewes continue to be both prolific of lambs and milk, and are excellent nurses, COTSWOLD-LEICESTER. — A very handsome cross-bred is pro- duced by the union of the Cotswold ram with the Leicester ewe. The fleece of this cross is of a silky fiber, beautifully waved and curled. The wool partakes of the fineness and luster of the Lei- - — _ 140 THE SHEPHERD'S MANUAL. \ It was found to maintain its original character perfectly, produc- ing a sheep which yielded a fleece of wool closer and finer than that of the Cotswold, but not so long, weighing from 11 to 13 Ibs., and a much heavier carcass of mutton of a quality equal to that of the Southdown which weighed, at three years old, 150 Ibs. The ewes are prolific, the lambs strong, healthy, and maturing quickly, reaching a live weight of 140 to 160 Ibs. at twelve mouths. They are found to be equally suitable to the light pastures of Long Island, with either the pure Southdown or the pure Cotswold, and are perfectly at home beneath the hot summer suns of our climate. It is a coincidence which is not at all remarkable, being founded on common necessities, that in producing this and other crosses, the Germans and ourselves have taken up the same materials to work with. The climates of both the United States and southern Germany are similar ; the summers are hot and dry, and the win- ters compel the use of preserved and dry food for a considerable length of time. The breeds which would be suitable to the mild, moist, and even climate of England, are not exactly adapted to Germany or the United States, and we must hesitate to follow, or must follow with great caution, the lead of the English breeders. But the example or success of the Germans may be made more safely applicable to our circumstances, inasmuch as the conditions in both cases are similar. This coincidence is a proof of the fact, that in working out these changes, breeders and farmers are forced to follow certain natural laws, and that as they work in conform- ity thereto, they succeed, but when they oppose these laws, they must necessarily fail. It is in exact accordance with this fact that we find it difficult or impossible to preserve, for any length of time, the condition of sheep imported from England, more especially of the more highly refined breeds ; but that we can easily accli- mate their produce, or build up cross breeds which will be more profitable and convenient for us to keep. With our wonderful diversity of climate, soil, and surface, and with the varied demand for staples for manufactured fabrics, there is opened a field for the exercise of the breeder's skill in producing new races to accom- modate these conditions, and to meet these demands, which is hitherto unexampled in the history of agriculture. This is no mere matter of conjecture. It has been clearly demonstrated by experience and practice. "Wool of the cross between the Cots- wold or Leicester rams on Merino ewes has been imported into New York from New Zealand and Australia, for some years past, to meet the demands of the manufacturers of delaines and other staple goods. Our wool-buyers have been in the habit of going to THE VALUE OF CROSS-BRED SHEEP. 141 142 THE SHEPHERD'S MANUAL. those distant countries to select wools suitable for their needs which they cannot procure at home. The heavy expenses involved act as a protection to this industry here, not to speak of the pres- ent import duty levied on foreign wools. Large quantities of this cross-bred wool are also used in England, where it cannot be pro- duced so cheaply as here. It would be strange indeed if we can- not, with our vast territory, equally favorable in climate and soil with those distant regions of the southern hemisphere, at least compete on equal terms with the shepherds of those countries, more especially as we enjoy an immense advantage, which they do not, in having a market at our very doors for the mutton which these sheep so profitably produce. In short, the production of American cross-bred sheep offers a most enticing field for experi- ment and labor both to the skillful breeder and the enterprising farmer. For the first in keeping up a supply of pure bred rams, and in improving their quality so as to meet the demand of the farmer ; and for the latter in seeking out, selecting, and using these pure rams on our native sheep with proper knowledge, judgment, and skill, so as to supply the demands of our own manufacturers at least, if not those of other countries. To do this there must be an actual contact and interchange of ideas and experiences be- tween the woolen manufacturer and fhe breeder and farmer, by means of which the needs of the one and the opportunities and duties of the others, may be mutually explained and made known. Neither branch of our native wool industry can flourish as it should and might without this interchange of views and the recognition of an identity of interest. CHAPTER VI. WOOL— ITS STRUCTURE AND USES. Wool in its character and structure in no respect differs from hair. When hair is soft, pliable, and of a spiral or wavy form, it is what we call wool. Wool, like hair, is the outer covering of some species of animals, and is a growth from the skin. The skin of an animal is a composite structure consisting of two portions, the outer and insensible layer called the epidermis, and a highly sensitive, vascular and nervous layer beneath this, called the STRUCTURE OF WOOL. 143 derma. It is in the derma that the hair is rooted, and from it that it is nourished. The hair, (or wool), consists of two portions, the shaft, or that which pierces through the epidermis and forms the outer coat or fleece, and the bulb or root which is imbedded in the derma. The bulb of the hair is rooted in a gland called the hair follicle, and from this it derives the cells which form the outer surface of the hair. These cells are converted into flat scales, in- closing the interior fibrous structure of the hair, and as they are successively produced, they overlap like shingles on a roof, or the scales of a pine cone, forming the imbricated coat of the hair to be hereafter described at length. Rising into the hair bulb is the hair germ, which furnishes the hair with nutrition, and the ele- ments of its growth. On each side of the hair follicle is a gland which secretes a viscid fluid. These glands, known as the sebace- ous glands, open by small canals into the sheath of the hair. Other Fig. 47.— SECTION OP SKIN HIGHLY MAGNIFIED, SHOWING THE GROWTH OF THE HAIB. sebaceous glands open independently upon the surface of the epi- dermis. They secrete a fluid which serves to lubricate the skin, and in the sheep supplies the oil and yolk that fill that pur- pose for the fleece and prevent any injury to the wool by con- tinued rubbing, or " cotting," or felting, in consequence of the wearing and friction, while upon the sheep's back. In a healthy skin this secretion with those of other glands, (called the sudori- 144 THE SHEPHERD'S MANUAL. parous glands), which are situated in the derma, amount to a total quantity which surpasses that of the evacuations from both the bowels and kidneys. In fig. 47 is shown the structure both of the skin and the hair, the engraving, (from Chauveau's Comparative Anatomy of the Do- mestic Animals), representing a section of the skin highly magni- fied. The epidermis is shown at A, the derma at B, the hair follicle at c, the sebaceous glands at 1, the bulb or root of the hair at 2, the hair at 3, a fat cell at 4, a sudoriparous or sweat gland at 5, and at 6 the excretory duct of this gland, or pore of the skin. Hair or wool is composed of three layers. The outer one, the epidermis, is very thin, consisting of the flattened cells or scales overlapping as previously mentioned. In wool these imbricated scales are highly developed, and fill a most important office, giving Fig. 48.— APPEARANCE OP WOOL WHEN HIGHLY MAGNIFIED. to it much of its value as a material for the manufacture of cloth. When examined by a microscope of high power,- a fiber of wool presents the appearance shown in fig. 48. The discovery of the serrated surface of wool which is generally attributed to Mr. Youatt, was previously announced by M. Monge, in Annales de Chimie, in 1795. This serrated or toothed surface confers upon wool its felting property. When wool is carded it is torn to pieces and mixed and twisted in every direction. The waved or curved structure of the fiber of some qualities of wool aids in this twisting and entangling of the fibers, (see fig. 49), and the points of the scales projecting as so many minute hooks hold the entangled mass together closely and firmly. Pressing, rolling, or beating CHARACTERISTICS OF WOOL AND HAIR. 145 the wool together, causes it to adhere in a compact mass, in other words causes it to felt firmly together, and the more firmly, the more it is rolled, beaten, or worked. These scales are very minute and numerous; in the length of one inch of a fiber of fine Saxony wool, there are no less than 2,720 of them ; in Southdown wool there are over 2,000, and in the Leicester wool there are over 1,800 of them to every inch. Upon the whole sur- face of a fiber of Merino wool one inch long and V75o of an inch in diameter, there are over 23,000 of these points. The more numer- ous they are, and the more waved or curled the wool, the better its f elting quality. The second layer, the cortical substance, is the thickest portion of the fiber. It also contains the coloring matter. It is fibrous and striped lengthways. The central portion of the fiber consists of the medullary substance, or marrow, and occupies a narrow, irregular cavity. Hair or wool is not hollow or tubular, as is frequently supposed, but solid, and consists of these three portions. The fiber grows from the root, and increases by addition of cells continuous- ly formed in the follicle. It is thus seen that the growth and per- fection of the wool depends in the most intimate manner upon the nutrition and perfect health of the animal. An interesting and valuable addition to the natural history of wool and hair has recently been made through some investigation ordered by the Secretary of the Treasury of the United States, for the purpose of identifying the presence of sheeps' wool in manufactured goods, the materials of which are ostensibly the hair of the cow and calf. The investigations were made by Professors John L. LeConte and J. J. Woodward, of Washington, D. C., with the help of a micro- scope magnifying nearly 100,000 times, (310 diameters). The full report of these investigators^ is published in the Bulletin of the National Association of Worn Manufacturers, Yol. V, No. 7, 1875, (Boston), a publication of the greatest value to intelligent wool- growers as to all woolen manufacturers. After describing the well known structure of hair and wool, the report proceeds : " But not- withstanding this similarity of structure, most of the individual 7 Fig. 49. — FIBERS OP WOOL. 146 THE SHEPHERD'S MANUAL. hairs of the cow and calf are so unlike the majority of those of the wool-bearing animals in their size and shape, that it might seem easy to make the distinction. They are much shorter, much thicker at their base, taper rapidly towards the point ; the medulla occupies a larger proportional part of the whole hair, and the free edges of the scales of the cuticle, which are so disposed as to form from twenty to forty imbrications to the Viooth of an inch, lie quite smoothly upon the surface of the hairs, so that their con- tours, as seen under the microscope, closely approximate continu- ous lines. These characters are so well marked that the coarser hairs of the cow and calf can readily be distinguished from the woolly hairs of any of the wool-bearing animals. On the other hand, however, the majority of the woolly hairs of the sheep offer a combination of characters which are never found in the hairs of the cow and calf ; namely, each of these hairs extends from half an inch to several inches in length without any medulla, and without perceptible taper. They present at frequent but irregular intervals, well-marked, one-sided, more or less spirally arranged thickenings of the cortical substance, which give to the wool its curly character. The mean diameter of each hair varies from Veooth to the Yioooth of an inch, or even less ; and the scales of the cuticle are so arranged that their free edges project somewhat, forming well-marked imbrications, of which usually from fifteen to thirty can be counted in the Viooth of an inch. The fine hairs of the goat and kid, from the Yioooth to the Yaoooth of an inch or less in diameter, also run from half an inch to an inch or more, without perceptible taper, without medulla, and are clothed with a cuticle resembling that of sheep's wool, but are almost, or alto- gether, devoid of the irregular thickenings of the cortical sub- stance which characterizes the latter. Similar hairs are found in certain deer, and some other animals, but never on the cow or calf." The report is accompanied by highly finished heliotype illustrations of samples of different kinds of hair and wool. The chemical composition of pure, dry wool, is as follows : COMPOSITION OF PURE WOOL. Carbon 49.25 per cent. Hydrogen 7.57 " " Nitrogen 15.86 " " Sulphur 3.66 " " Oxygen 23.66 " " 100.00 " " The fibers of fine wool are very closely seated upon the skin. The pure Merino has from 40,000 to 48,000 fibers on a single THE YOLK OF WOOL. 147 square inch ; the original coarse wooled breeds have from 5,000 to 6,000 fibers on an inch. The twentieth cross of a pure Merino ram upon a coarse wool race had no more than 25,000 fibers to the square inch ; this fact shows very forcibly how long a period it may take to remove the effects of one cross, for if this state- ment be true, the presence of only Yi,048,687, (less than one mil- lionth part), of impure blood is sufficient to reduce the fineness of the fleece nearly one-half. The yolk which is secreted from the glands of the skin is an alkaline substance, partaking of the char- acter of a soap. At its secretion it is liquid, and in some breeds of sheep it remains in this state, moistening and softening the fleece ; in other breeds, particularly some families of the Merinos, the yolk thickens or dries into a sort of gum or wax of an orange yellow color, which adheres to the wool in scales, and greatly adds to its weight. The yolk or " suint " has been found by Dr. Voelcker to consist of a combination of fatty acids with potash, forming a potash soap which is soluble in water. When dried, the yolk contains 59 per cent of fatty compounds, with some nitro- gen, and 41 per cent of mineral matter, of which from 60 to 84 per cent is potash. In some places this potash is profitably recovered from the refuse liquid of wool washings. In November, 1865, Maura ene and Rogelet communicated to the Chemical Society of Paris, the details of their experiments on the nature of suint, •which led them to take out a patent for the manufacture of potash salts from this source. They showed that suint is made up of wulral fatty salts containing much potash, but not more than traces of soda, and rarely even that; that the soluble portion yields on evaporation and calcination a mixture consisting mainly of carbonate of potassium, with chloride, sulphate, phosphate, and alumino-silicate of potassium in smaller quantities, also a little lime, magnesia, and oxide of iron and manganese, the average composition being Carbonate of potassium 86.78 Chloride " " 6.18 Sulphate « " 2.83 Other substances 4.21 100.00 The yolk soluble in water forms from 20 to 22 per cent of the weight of the fleece, and besides this, the fleece contains from 7 to 10 per cent of oil, which is not removed in ordinary brook wash- ing unless it be in part dissolved by the action of the supera- bundant potash of the soapy yolk. When the oil and yolk are removed by washing, the wool becomes harsh and dry to 148 THE SHEPHERD'S MAKUAL. the touch. The presence of a considerable amount of yolk in the fleece is justly supposed to indicate a superior quality in the wool, and -while excessive yolk is undesirable, it is a disputed point just •when that excess begins. A fleece of Merino wool that loses one- half in washing, can scarcely be said to have an excess of yolk. Many breeders do not hesitate to go beyond this, and insist that no amount of yolk can be called excessive. In this view they are supported by the high authority of Mr. Youatt, who has said : " farmers never bestow a thought on yolk, and neither understand nor care about it ; this question without doubt will some day be regarded as one of the very cardinal and essential points of the sheep." Mr, Randall, our highest authority on fine wool, in his work previously referred to, does not favor the production of yolk to an excessive extent. He very justly remarks that when manu- facturers cease to pay the same price for excessively yolky wools as for those which are only moderately yolky, the breeding of sheep that produce four pounds of yolk for one pound of wool, must go out of fashion. Perhaps this matter may safely be left in the hands of the manufacturers, who are not apt to pay for what they do not want ; and while they continue to buy excessively yolky wool, it will be most profitable for the farmer to produce it. CLASSIFICATION OF WOOLS. Wool is generally classed as short and long. It is also graded as superfine, fine, medium, and coarse. The terms carding and combing wools are no longer sufficiently distinctive, as many kinds of wool are now combed that were formerly carded, and the continued improvement of combing machinery gradually adds to the list of combing wools. Merino wools of less than three inches in length are now combed, as are the short wools of the Southdown grades. It is very important for wool-growers to know exactly the wishes and needs of the wool manufacturers, and to seek this knowledge should be their constant aim. At present, and for some time past, the coarse and medium wools have, in many parts of the country, borne the same price as the finest Merino wools ; in some markets fleeces of one-quarter and half-blood Merinos have sold for more than those from full-blood animals. The quotations of wool hi the New York Mercantile Journal of July 29th, 1875, were as follows: NEW YORK, MICHIGAN, AND INDIANA WOOLS.

The demand of manufacturers is clearly for medium wools, the 3 reduce of half-bloods or grade Merinos, or of crosses of Merinos with Southdowns. The chief difficulty in wool-growing is the tendency on the part of farmers to run in a crowd upon the same variety and quality ; at one period it will be fine wool, at another combing wool, and often they are led to breed without knowledge or judgment. A great variety of wools is needed to meet the de- mands of manufacturers, and .when a farmer has become possessed of a flock of the right sort, his best course is to keep to it, and not change because a temporary decline in his class of wool discour- ages him for a season. In addition to these grade Merino wools, there is a constant and increasing demand for combing wools for worsted and coarse fabrics. Combing wools are those fitted for a process known as combing, which consists in drawing out the fibers so that they are straight ^nd parallel, the shorter portions of the wool called " noils " being removed by the operation. The fibers are then spun into worsted yarns ; the ends of the fibers being covered in the spinning, these yarns are smooth and lustrous. In carding, the fibers are placed in every possible position with regard to each other ; the ends projecting from the yarn, form a nap hi the woven fabric which covers and hides the threads. Carding wool must therefore be short and full of curls ; combing wool, on the contrary, needs to be long and free from curls and of a bright and lustrous surface. Long Merino wools, although they are combed for making fine cloths without nap, and for delaines, cashmeres, coburgs, and other dress goods, are not designated combing wools, but as delaine wools. Common flannels require in their manufacture the coarsest common native wools up to medium Merino wools. For fine flannels, fine to the finest wools are used; for blankets, the most ordinary native wools, " noils," medium Merino wools and South- down and grade Southdown wools are used. For shawls, all grades of Merino wools, up to picklock, are used ; some fleecy varieties are made of worsted combing wools ; felted cloth skirts and other goods are made of the lowest grades of wool, but the 150 THE SHEPHERD'S MANUAL. finer kinds, as piano and table covers, are made of medium Merino wools. Knitted goods, such as undershirts, vests, drawers, hose, etc., require a great variety of wools from the lowest qualities up to the high grades of Merino ; certain fancy varieties requiring the finer kinds of combing wools. Fancy cassimeres, meltons, beaver cloths, and overcoatings, require chiefly medium grades of Merino wool, a small quantity only of the finer grades being re- quired for the best qualities. For mixing with shoddy, which is an extensive manufacture, the finest and longest Merino wools are found the most profitable, as such wool carries the greatest quan- tity of the short fiber of the substitute. Ladies' cloths, cloakings, and thin dress goods require fine long Merino wool ; the finest and longest Merino wool is used for men's fine worsted coatings. Serges, moreens, alpacas, lastings, mohair lusters, furniture dam- ask, reps, bunting for flags, webbings of all kinds, sashes, picture cords, tassels, and soft goods, such as nubias and shawls, braids and bindings, are all made of the long combing wool of the Lincolns, Leicesters, and Cotswolds, or their grades. For various carpets, coarse Texan or Mexican and California wools are used, and similar grades of foreign wool known as Chili and Cordova carpet wools. This enumeration indicates as closely as need be, what kinds of wool the American farmer may grow with safety and without risk of wanting a market. Considering that the imports of wool of many of the grades mentioned, and of the recapitulated woolen goods, amount every year to fifty mil- lions of dollars or over, there would certainly seem to be no danger that the farmer will lack a profitable market for any kind of wool he may find it convenient to grow. PURE AND GRADE MERINO WOOL. It will be noticed how large a proportion of the foregoing man- ufactures derive their material from the Merino, either directly in its pure state, or indirectly as grades or cross breeds. Some infor- mation as to the character of the Merino wool, and the tests by which superior breeding animals may be known and selected for the improvement of native sheep, will therefore not be out of place. The character of a Merino fleece may be judged by the following tests, viz : Strength of Fiber.— This is indicated by the amount of grease in the wool, abundance of oil or yolk indicating a healthy condition of the animal. The first sign of disease is a change in the charac- ter of the secretions, and the skin being the chief secreting organ of the body, it is there that the change may be soonest noticed. HOW TO JUDGE WOOL. 151 The moment the health of the sheep fails, the growth of the wool is arrested, along with the secretion of the oil or yolk, and the continuity of the strength of the fiber is destroyed to the great reduction of its value. Fineness. — In a perfect fleece, the wool should be equally fine over the whole body ; coarser wool may be looked for, if any- where, on the top of the shoulders and the rump, and a weaker quality on the breast and belly. The finest wool is but V13oo of an inch in thickness, ordinary wools YTBO to YSSO of an inch in diameter. Curl. — The curl of the wool is very important. This is the waved or crimped character of the fiber which in the perfect wool consists of minute bends or crimps. There should be a perfect regularity in these waves, which ought not to be so abrupt as to appear as folds. In very fine wool there should be at least 30 of these waves to the inch in length. (See d, e, fig. 49.) Thickness. — This quality refers to the closeness of the fibers upon the skin. A pure Merino should have from 40,000 to 48,000 fibers upon every square inch of its skin. The weight of a fleece must necessarily depend on this characteristic. Closure of the Fleece. — The closure of the fleece on its outer surface is of great importance, for the reason that a well closed fleece is im- pervious to dust and dirt which would otherwisefind its way into the wool and injure its quality. The closure is ef- abundance of yolk Fig. 50. focted by the Fig. 51. which gathers at the ends of the wool, and mats the fibers together. The viscid gum gathers dust, that coats the fleece with a black surface, which feels to the hand as a firm crust. When the crust is pressed the elasticity of the fleece is at once perceived. Upon parting the fleece to inspect the wool, the experience or ignorance of the operator is at once perceptible. He should grasp the fleece at the points of the fibers with the fingers and thumbs of both hands, and part the surface 152 THE SHEPHERD'S MANUAL. Fig. 52. Fig. 53. gently, exposing the wool to the skin. The wool, on opening the fleece, should appear beautifully white and glossy, or rich yellow or orange colored, according to the style of the sheep. The fleece is then closed carefully without allowing any dust to fall down into the opening. The appearance of the open fleece should be banded with varying colors of light and darker yellow or orange, as in fig. 50, or when opened, as a cup in fig. 51. .A well closed fleece will exhibit a surface as shown at fig. 52, and a badly closed one will appear as at fig. 53. The well closed fleece is di- vided into small sections, which are tabular or flat and smooth upon the surface ; when the fleece is uneven in length, it cannot close well, and a few fibers only are matted together ; the surface is then dotted and not smooth ; this forms the defect known as " toppiness" The defects in wool may be enumerated as follows : " Stripy " or Watery Wool, generally shows itself in inferior ani- mals on or near the shoulder, where the best wool ought to be. The wool subject to this defect is devoid of those beautiful natu- ral curves or waves which are characteristic of really good wool. When compressed in the hand, it has no elasticity, and handles in a dead and lifeless manner, more like flax than wool. Such wool is only fit for making inferior goods. This defect is a sure proof of impure blood, and no sheep exhibiting it should be bred from. Toppiness is not of much importance as affecting the quality of the wool, but it indicates a defect in the breeding of the sheep. It has already been described. When this defect, however, extends to a matting together of the wool at the ends of the points, a quantity of noils are made in working the wool, and there is a waste. When toppiness is found in the fleece of old sheep, it be- comes a more serious objection, as it is quite possible that a lamb's fleece may be toppy by reason of uneven growth in its early life, and after having once been shorn, the defect may not reappear. Broad-topped Wool is seriously defective, and very decidedly reduced in value ; no animal having this defect should be kept in a flock having any pretentions to character for excellence. It consists in an interlacing of the ends of the fibers which are split from the top downwards. The fleece appears in good condition superficially, with a good even top, but the surface is divided into DEFECTS OF WOOL. 153 broad masses or " tops," and when one endeavors to part these to examine the wool, the mass is found to be almost felted together, and must he torn apart. This matted wool is dead, and breaks off in the process of manufacture, causing very great loss of material. Felty Wool is that which has a tendency to felt together on the sheep's back. The defect is caused by an absence of yolk, and in highly yolked sheep, by a continued wet season, which washes the yolk from the fleece. It is a direct result of low condition from poor feed, or of chronic ill health. Some sheep are consti- tutionally subject to "felty wool," and should be weeded out of the flock. Cloudy Wool is that which adheres together from the bottom of the fleece upwards, but not in so great a degree as in felty wool. A flossy appearance is discovered at the bottom of the staple, which is removed by the comb. In clothing wools this is not so objectionable as in combing wools ; in the latter the floss is thrown out and becomes waste. This is also a constitutional defect, and sheep so affected should be weeded out of an otherwise good flock. Kemp is very easily detected, and although it may be found in but a few spots at first sight, it indicates that it exists all through the fleece. It consists of coarse, white hairs, projecting from the surface of the fleece, on the face, the forearm, the inside of the flank, and in rams on the scrotum also. Whenever it is apparent in these places, it will invariably be found through the greater part of the fleece, chiefly on the whole of the belly, half-way up the sides, on the rump, thighs, and shoulder. In these places, short white hairs will be found in the staple, at the roots of the wool ; and as these hairs will not take any dye, they injure the fleece for the manufacture of dress goods or fine cloths. Kemp lessens the value of the wool nearly or quite one-half, and should make a breeding animal worth no more than its weight as mutton. On some heavily wrinkled Merino sheep, these kempy hairs may be seen on the edges of the wrinkles, and on the back of the head, but nowhere else. But it is even then a fatal objection to such sheep as breeders, for this is kemp, and may appear in all the pro- duce of such sheep, and there can be no certainty but some of the produce may be badly affected. Break in wool renders the fleece absolutely worthless for any combing purpose, and however fine the staple, or otherwise good in quality, it can only then be manufactured into a class of goods for which inferior wool is used. It is exactly what its name im- plies. When a breachy staple is taken and stretched, it parts with 154 THE SHEPHERD'S MANUAL. great ease at the middle or some portion of its length. There is a weak spot, and if the fiber is examined with a microscope, it will be found very much attenuated at that spot, and of a dull, dead appearance. From what has been already said about the structure and growth of wool, it will be easily understood that when by bad management, neglect, starvation, overfeeding, irreg- ularity in feeding, want of water, or any other evil which affects the condition or health of the sheep, the growth of the wool is temporarily stopped, even for a day, this suspension of growth must inevitably be marked by a weakness in the fiber, which can never be remedied. As the wool grows, this weak spot is carried forward, and if the evil is soon removed and the sheep recovers quickly, it is still there and there it remains. No defect is so fre- quent as this ; to avoid it, the flock must be kept with perfect regularity, and must receive no check for however short a time it may be. This involves the most skillful and careful management, which is unfortunately too rare. Regular poor feed may make an inferior staple, but one worth more than a breachy staple, which may result from one single neglect in the course of a season. Want of water causes more break in wool thr.n any other evil to which sheep are subjected by careless owners or ignorant shepherds. Uniformity in the fleece covers many minor defects, and to de- termine the evenness or uniformity of the fleece, the shoulder is first examined. Here the finest and best wool should be found. Taking this as the standard, the wool from the ribs, thigh, rump, and breech, is compared with it ; the nearer the latter ap- proaches this in quality, the better. If it is all equal in fineness, the fleece will be " even " in regard to fineness. If the wool on all the parts mentioned is reasonably regular in length, and near to the standard in this respect, the fleece is " even" as regards length of staple. The density is then tested. The hand is closed upon a portion of the rump and on the loin, and if the fleece is found to be as dense and elastic or springy on those parts as it is at the shoulder, the fleece is " even " as regards density. A perfect fleece will be found of nearly equal fineness from the shoulder to the thigh; of nearly equal length at the shoulder, rib, thigh, and back; of equal density on the shoulder and across the loins, and free from any of the defects before mentioned. Most of the points here indicated, both as regards defects and good qualities, refer to other wools as well as to that of the Meri- no; those points which depend on the peculiar character of Merino wool and its excessive yolkiness will be readily understood as necessarily applying to that alone, and those which depend on WASHING WOOL. 155 the organic structure of wool and the condition of the sheep, to all sorts of wool alike. Wool in its natural condition contains many impurities, dirt of all kinds, sand, dung, and the usual secretions of the skin, and be- fore it can become fitted for the uses of the manufacturer, it must be freed from these impurities. The wool-buyer, who generally comes between the farmer and the manufacturer, does not demand that the wool should be thoroughly cleansed, but only freed from its grosser impurities. No washing that the farmer could give his fleeces would be sufficient for the purpose of the manufacturer, who scours the wool in hot soapsuds before he can cleanse it suffi- ciently. But nevertheless, the buyer prefers the fleeces to be partly cleansed, and this partial cleansing is what is generally known as " brook washing." WASHING THE WOOL on the sheep's back is the usual practice. There are several methods of doing this. Where a brook or river can be used for the purpose, all that is needed is to choose a place where the water is waist deep, and the bottom is gravelly. A muddy or sandy bottom is to be avoided, as it will be impossible to prevent some of the bottom from being stirred up and mingling with the fleece. Cases have been known in which such a bottom has been chosen for this purpose with the special object of adding to the weight of the fleece by the admixture of sand. It is hardly necessary to say that this mode of cheating can never be profita- ble ; if one lot of fleeces thus adulterated be palmed off upon the buyer, his remedy may be a severe one, and at the best the cheat will not be forgotten. Generally, however, buyers are not to be imposed upon, but look sharply enough after their own interests to discover all attempts at dishonesty, and to make the perpetrator pay soundly for his error. In washing and making up wool, the most thorough honesty will be found to pay well in the long run, and a reputation for fair dealing will often be found to have a direct money value, especially when the market happens to be against the seller. Soft water is to be preferred for washing wool. Hard water leaves the wool harsh and dry to the hand, and detracts from its appearance in the market. Soft water leaves the wool soft and mellow, and it more rapidly recovers it? tone and elasticity when washed in water free from lime. The ground having been chosen, the sheep should be closely penned upon the bank of the stream ; the side of the pen next the stream should be narrow, with a pas- sage-way leading to the water. A plank platform, projecting over the bank, from which the sheep can be plunged directly into the 156 THE SHEPHERD'S MANUAL. water, is very convenient. The washers enter the stream and re- ceive the sheep from the hands of the drivers, plunging them bodily beneath the surface, two or three times. - In catching the sheep and handling them in the water, the assistants should avoid pulling the wool. If a sheep is hauled around by the wool, the skin is bruised, and, the wool is injured and weakened at the bruised spots. To catch a sheep it should be seized with the right hand by the hind leg above the hock, firmly with the whole hand, yet without unnecessary violence. The pressure upon the sinew above the hock joint paralyses the leg for a moment, and the sheep will rarely struggle. The left hand is then slipped around the breast, and the shepherd has perfect control of the heaviest sheep, without pulling in the least upon the wool. A crook, fig. 54, is a convenient implement with which to catch wild or unruly sheep. It is quietly passed in front of the leg, which is seized and held while the shepherd secures the sheep in the way described. After the sheep is thorough- ly soaked, the animal's head is held above water, while the fleece is shaken and squeezed, so as to free it from dirt. As many as pos- sible of the tags and matted locks around the breech should be opened and cleansed. When this has been done, the sheep is passed to another washer, who finishes the washing, and directs the sheep to the bank, squeezing the water from its fleece as it emerges from the stream. A clean, grassy bank should be chosen. Some long wool sheep, with heavy fleeces, which hold a great quantity of water, may need some help to get upon their feet as they reach the bank. Ewes that have not lambed should be handled carefully in the washing, although it is rarely, in well managed flocks, that ewes are allowed to be in lamb at this time. This method of washing is often very disagreeable and injurious to those who practice it. Where ague is prevalent, or where rheumatism is feared, it is better to choose some other plan. A rough dam may be made in a small stream, and a spout placed in the dam. beneath which the sheep may be washed. A sparred roadway may be laid across the stream, through which the water will escape. By wearing rubber thigh boots, and a rubber apron, the washers may be kept dry, and avoid the danger of long con- WASHING THE SHEEP. 157 tinued exposure to chilly water. In fig. 55 is au illustration of this method of washing. For a large flock, the spout may be made to extend across the whole dam, so that several sheep may be washed at the same time, each sheep being passed from hand Fig. 55. — ARRANGEMENT FOR WASHING SHEEP. to hand, until finished by the last one. With sufficient help, one sheep per minute may easily be washed by this method. After the sheep are washed, they should be kept in a clean field, and in a clean yard at night, for the week at least before shearing, to per- 158 THE SHEPHERD'S MANUAL. niit the fleece to dry and to regain sufficient yolk to recover a soft and mellow handling. TAGGING AND TRIMMING THE FEET.— If the sheep are very dirty, and have not been kept trimmed about the tail, it is advisa- ble that they should be tagged before they are washed. The coarse soiled tag-locks about the hinder parts, and the belly of the rams and wethers, may be clipped off in the spring and thrown into a basket or barrel to be soaked and washed by themselves. The same time will be the most convenient to trim the feet, which is a more necessary thing to do than is generally supposed. The toes of old sheep, upon soft pastures, will grow long and turn up, and cause lameness, or the soles and edges of the hoof will become ragged and worn, the horn turning under at the edges. In this condition the feet gather filth or small stones and gravel, which work into the hoof and cause disease. Foot-rot is in many cases thus engendered. The feet should then be trimmed at washing time, if not oftener. A sharp knife may be used to pare the ragged edges of the hoof and the sole, and toe nippers to shorten the toes. A pair of common wire-workers' cutting nippers may be used for the latter purpose. The edge of the nippers should be filed sharp, with the bevel on the inside, and brought to a smooth edge with a piece of oil-stone. SHEAKING. — Sheep should not be shorn until the weather has become warm and settled. May is the usual time for shearing in the northern states. The tools of the shearer are a pair of shears, and if desired, a shearing-bench upon which sheep may be placed to avoid the necessity of his stooping so much as is required when the sheep are laid upon the floor. The common shears with a thumb piece upon one side, and an easy spring no stronger than will be sufficient to make the shears open freely when released from pressure, is the best tool for the shearer. Several new and patented shears have been introduced, which the inventors claim may be used even by inexperienced persons without danger of cutting the sheep's skin. A trial of these shears does not support this claim, and the common shears are not yet superseded by any of these so-called improvements. The shears should be brought to a fine, sharp edge upon a fine oil-stone. The bevel of the cut- ting edge should be about 35 degrees, or somewhat more than that of a common pair of scissors, and less than that of a plane iron. The floor of the shearing room should be kept perfectly free from straw, chaff, or litter, and if a boy is kept constantly at work with a broom hi his hand removing dirt, tags, and rubbish, his SHEARING. 159 time will be well employed. The shearer has better control over the sheep when on the floor than on the bench, and the handling is not the same under both circumstances. In shearing on a bench the shearer catches the sheep by the left hind leg, backs it towards the bench, and rolls it over upon it. He then sets the sheep on its rump, and standing with his left foot upon the bench, lays the sheep's neck across his left knee, with its right side against his body. The two forelegs are then taken under the left arm, and the fleece is opened up and down along the center of the belly by small short clips with the shears. The left side of the belly and brisket are then sheared. The tags are clipped from the inside of the hind legs and about the breech, and thrown upon the floor. They should be swept up at once and gathered into a basket, and by no means allowed to mingle with the fleece wool. The breech is then shorn as far as can be reached. The wool from the point of the shoulder is then clipped as far as the but of the ear. The wool is shorn around the carcass and neck to the foretop, pro- ceeding down the side, taking the foreleg and going as far over the back as possible, which will be two or three inches past the back bone. When the joint of the thigh, (the stifle), is reached, the shears are inserted at the inside of the hock and the wool shorn around the leg back to the thigh joint. The wool over the rump is then shorn past the tail. The sheep is now completely shorn on one side, and two or three inches over on the other side, along the back from neck to tail. It is then taken by the left hind leg, and swung around with the back to the shearer, leaving some wool beneath the left hip, which will ease the position of the animal, and keep it more quiet. The wool is then shorn from the head and neck down the right side, taking the legs and brisket on the way. The fleece is now separated. The job is completed by clipping the tags and loose locks from the legs. To shear on the floor, the sheep is set upon its rump, with the head thrown back beneath the left arm of the shearer, and its back toward him. The wool is then opened at the neck, and clipped downwards in regular lines on the right side from belly to back, and over the spine as far as possible on the other side in much the same manner as has already been described. The sheep is then laid on its shorn side, and the shearer, kneeling on the left knee, and straddling the sheep, with the left foot laid over the sheep's neck, removes the fleece from the left side, and finishes by removing tag locks from the legs and scrotum. In bad shear- ing, the greatest injury to the fleece takes place on the back, and is caused by the operator .not raising his hand, so as to keep the 160 THE SHEPHERD'S MANUAL. points of the shears close down to the skin. This is known as " cutting through ; " it takes place when the sheep is being shorn on one side ; and, in shearing over the back, the points of the shears cut nearly or quite through the fleece, from the inside to ths out ; then, when the animal is being shorn on the other, or " turning out " side, the shears are again pointed upwards, and the cuts on the first and last side overlap each other, causing the fleece to part in two halves all along the back. No good shearer makes second cuts; the fact that wool has been left by the first cut proves that the shears have not been held properly ; and the wool removed by a second cut being perfectly useless, entails a severe loss on the manufacturer, and greatly lowers the repute of the brand in the markets. Cutting through, and a habit of continually making second cuts, are the most objectionable characteristics of the unskillful shearer. A sheep may be shorn so close as to satisfy the most exacting employer, and yet it may be shorn very badly ; and the only conclusive test of good shearing, or the reverse, is to be found not on the outside of the animal, but on the inside of the fleece. "When the sheep's skin has been unavoidably cut in shearing, each cut should be smeared with tar, which will prevent flesh flies from depositing their eggs in the wound, and probably avoid after trouble. It is said to be a fact that newly shorn rams are incapable of breeding until their fleeces have recovered considerable growth. Some evidence in support of this assertion is given in a pamphlet published in Australia, in which the author, Mr. J. B. Graham, the superintendent of an extensive sheep "station" on the Murray River, states that in a flock of 4,000 ewes and 100 rams newly shorn, he had but 165 lambs, and on another occasion a flock of 100 ewes, which were drafted with 4 rams, newly shorn, produced only 9 lambs. On another station when the ewes were coupled with newly shorn rams, there were not 5 per cent of lambs. This, if a fact, is more curious than important in this country, where, except in California, sheep are not shorn near the breeding season. If wool were not shorn, it would be shed annually, or its growth would be rendered uneven, and its fiber weakened at the season when the coat of an animal covered with hair is usually shed. A fleece that is suffered to grow for two seasons, shows very dis- tinctly the division between the growth of each year. This, how- ever, occurs only in those countries where the winter and summer climates differ considerably, and where the transition from one to the other is sudden. Where the climate is nearly even throughout TYING FLEECES. 161 the year, as ir. California or Australia, the fleece will continue to grow on, without change. At least this is the case with the Meri- no, whose fleece has been known to grow to a length of 22 inches in a continuous period of six years hi Australia. In California a fleece was shorn in 1874, which weighed 52 pounds; this was doubtless the result of two or three years' growth. The retention of the fleece for an indefinite period is a peculiarity of the Merino, which is not known to appertain to any other variety of sheep. PACKING THE FLEECE. — The manner in which the fleeces are made up has no little influence upon the price at which the wool will sell. Wool buyers prefer to have the fleece loose, light to £. 56.— TABLE FOB TYING WOOL. handle, and elastic ; and tied up so that it can be easily opened if need be. The method of packing in Ohio and Western Pennsyl- vania, is to lay the fleece upon a table, turn in the head and tail, then the flanks, and roll it up in a neat roll, tying it with a string at each end. This method is shown in figure 56. Sometimes the fleece is tied with one more string across the ends, but this is rarely necessary, excepting when the wool is very short. A fleece thus tied is light, easily handled, shows the quality of the wool, and can be felt all through. The effect of the manner of putting up the fleece is seen in the following quotations taken from the wool market report of Coates Bros., Philadelphia, of July 1st, 1875. 162 THE SHEPHERD'S MANUAL. Ohio, Pennsylvania, and "W. Va. fleece 50c.(_ New York, Michigan, and Wisconsin fleece, XX..46c.(g Illinois, Iowa, and Missouri fleece, XX 45c.( The difference of 4 to 5 cents per pound is the value of the extra care in making up the fleeces. The difference is even greater than this, for New York, Michigan, andWisconsin wools of better qual- ity than some Ohio wools, are bought at the regular rates quoted, simply be- cause the Ohio fleeces come to market in better shape. This is no unreasonable dis- tinction, as will be seen when the man- ner of sorting wool is explained fur- ther on. There are various kinds of wool tables for packing the fleece other than that shown in figure 56. One hi common Fig. 57. — PLAN OF WOOL TABLE. use in New York is thus described in the American Agriculturist of May, 1872, with the accompanying engravings, to which the letters refer.

A hook is made, (e, fig. 58), of hard wood, one inch thick and fourteen inches be- tween the jaws, and the box is done. To use it, first fix the strings from the cuts d, d, d, d, in the di- rection of the dotted lines on fig. 58. Lay the fleece with the clipped side down- wards on the boards, bring up the sides, which secure by placing across them the hook, as in fig. 58 ; then close the ends, which the springs will keep in their places ; tie the ends of each string tight- ly over the wool; then remove the hook, and the box will fall back, leav- ing the fleece tight- ly packed and tied. Nothing should be tied up in the fleece, nor should coarse twine nor too much twine be used. All tags and waste wool should be scrupulously kept out of the fleece, as it should not only look good, but should be good. This observing of little things is one of the ways in which wool growing is made a profitable business. Tag locks and dirty wool should be washed in a tub with soft soap and cold water and sold by itself. The soft soap tends to give tub- washed wool a mellow handling free from harshness. When the grower ships his wool to a distant market, he necessa- rily packs the fleeces hi bales. The bale should be solidly packed Fig. 59.— PACKING WOOL. 164 THE SHEPHERD'S MANUAL* both for economy in freight, which in light bulky articles, is charged according to bulk and not by weight, and for the better condition of the fleeces on their arrival at their destination. A convenient method of baling the fleeces, is to hang the sack from a trap-door in the wool loft, as shown in figure 59. The fleeces are handed or thrown to the packer, who places them in the sack, pressing them down close with his bare feet, and, as he reaches the top, with his knees ; a handful of tags is put in each corner of the sack and tied tightly to make a handle by which the package can be hauled about in its transportation to market. When filled, the bale should be plainly marked with the exact weight, tare, and net weight, upon one of its sides. SORTING. — When the wool reaches the dealer, it undergoes a process of sorting. The same fleece contains wool of various de- grees of fineness, and it must be prepared for the manufacturer, who purchases only exactly what he needs for his particular use. The fleece is unrolled, and the sorter selects the fine locks from the coarse ones; the neck, shoulder, and side wool from the thigj, and haunch wool ; and this from the belly and breech wool. Each fleece is sorted into from six to ten different qualities, which are selected by the sorter with surprising quickness and certainty. A well rolled fleece is much more quickly handled than one made up disorderly, and the saving of the time of a highly paid workman, is of itself sufiicient to enhance the value of a well packed fleece over that of an opposite character several cents a pound. The final disposition of the wool, after it has reached the manu- facturer, is not within the limits of this book, although the vari- ous processes of scouring, dyeing, oiling, plucking, carding, comb- ing, breaking, drawing, roving, spinning, reeling, and weaving, are all of the greatest interest to the wool grower, as relating very intimately to his share of the general industry, and showing how far the best management of his flock goes to ease the labors, and facilitate the operations, of the numerous artisans concerned in all these various branches of the manufacture, and consequently adding to the value of his raw product. The perfection of the various processes cannot be better illustrated than by the facts that in only ordinary spinning, a pound of wool is made to extend three-fourths of a mile ; in superfine spinning, it stretches to a dis- tance of 22 miles; and that the very finest woolen yarn hitherto spun, will reach a distance of 95 miles for every pound. Fifteen hundred fibers of the finest wool laid side by side will cover only one inch of space, and 2,225,000 of them placed compactly to- gether, will make a bundle only one inch square. How much evil WOOL PRODUCTION OF THE WORLD. 165 then may the ignorance or carelessness of the shepherd or the wool-grower, work to the possible benefit to the world through this industry, by reducing the value of a staple upon which so much of the labor of mankind is expended. The wool production of the whole world is estimated by Mr. H. C. Carey, at 1,800,000,000 Ibs. This estimate is rendered proba- ble by comparison with the estimates of the production of those countries of which we have more or less accurate knowledge through official reports. An estimate of the number of sheep and pounds of wool produced in the following countries in 1866, made by the London Statistical Society, and published in their journal, here reproduced. To this is added in the last column the number of sheep mentioned as existing in those countries in the official reports ef their governments published since that date : TABLE OF SHEEP AND WOOL PRODUCTIONS OF THE FOLLOWING COUNTRIES IN 1866.

When we take into account along with this, the lower price of our lands, the American shepherd will be seen to have a far more profitable business than that of any other sheep owner in the world. Much of this advantage is doubtless due to the higher prices received by the wool-grower through the operation of the protective duties levied upon foreign wool. Some of it is cer- tainly due to the greater weight of the fleece consequent upon the improvement which has been made in our sheep. With two ex- ceptions the average weight of American fleeces is the highest in the list. But by far the greater advantage exists in the higher comparative price of wool, which is only exceeded very slightly in two instances, those of Spain and Germany, and in these countries the bulk of the wool is of the finer sorts which bear a high market value. The benefit accruing to wool-growers by the present tariff is unmistakable, and although this is not the place to discuss the question, it continuance would certainly seem to be very desirable.

For instance, the estimated clip of wool in California, as reported by Messrs. E. Grisar & Co., of San Francisco, for the three decennial periods named, and for 1875, was as follows : 1854 175,000 Ibs. 1860 3,055,325 »« 1870 30,072,660 " 1875 43,532,323 " 168 THE SHEPHERD'S MANUAL. "While some of this very great increase will result from the rapid improvement in the character of the sheep, yet there is neverthe- less reason to suppose that the number of sheep in California now reaches at least 5,000,000, which is nearly double the number of 1870. In Colorado, persons engaged in the sheep industry, estimate the flocks to amount to about one million ; and in the neigh- boring territories of Dakota, Wyoming, New Mexico, and Arizo- na, this industry has become so wonderfully developed during the past five years, that a reasonable estimate would give the whole present number of sheep pasturing upon those plains as at least 2,000,000, where in 1870 there were little more than 120,000. The profitable character of the business of rearing sheep upon these magnificent and costless pastures, is tending to still further attract the attention of stock men and capitalists, who are establishing flocks in almost every available portion of these territories. A business in which capital used with care and skill returns a profit of 75 per cent, cannot fail to become developed with rapidity in so favorable a locality. What the limit of the productive capacity of these broad pastures may be, it would be hazardous to attempt to prognosticate. CHAPTER VII. THE ANATOMY OF THE SHEEP; ITS DISEASES AND THEIR REMEDIES. GENERAL VIEW OF ITS ANATOMY. The structure of the sheep more nearly resembles that of the ox than any other of the domestic animals. It possesses a less degree of nervous energy than the horse, ox, .or pig, but it is capa- ble of enduring greater extremes of heat and cold with less incon- venience, and possesses a more vigorous digestion than those ani- mals. The most of its nervous energy is expended on its diges- tive and assimilative functions, and the least proportion upon its sensitive and locomotive organs. None of our domestic animals so completely digests coarse fodder, or so thoroughly and profita- bly turns the most nutritious food into flesh and fat as the sheep. THE BOKES. 1G9 In this respect it is the most valuable and profitable feeder the farmer can make use of ; at the same tune no other animal is so feeble and defenseless, nor so soon succumbs to disease of a debil- itating or exhausting character. Its circulatory system being weak, it is on the other hand comparatively free from inflamma- tory diseases, to which the horse and ox are especially subject. This peculiarity of the character of the sheep may be inferred from a view of its skeleton, fig. 60, in which the small space occu- — SKELETON OF THE SHEEP. pied by the heart and lungs, is very marked in comparison with the large abdominal space which gives ample room for the diges- tive organs. The bones of the sheep number 226, including 32 teeth. These bones are disposed as follows : Vertebral column .................... .................. 43 Head, (without teeth) ................................. 28 Teeth, (in the adult) ................................... 32 Thorax or chest ........................................ 27 Shoulders ...... ..... ............. .................... 2 Arms and forearms ..................................... 6 Fore feet, (20 in each) .......... ........................ 40 Pelvis ................................................ 2 Thighs and legs ................... 8 Hind feet, (19 in each) ................................. 38 226 The structure of the head of the sheep is such as to secure great strength. In horned sheep, the upper portion of the skull is more strongly built than in the polled or hornless ones. This structure is necessary to protect the brain from the shocks consequent on the mode of warfare of the rams, which are pugnacious annuals. 8 170 THE SHEPHERD'S MANUAL. and especially of those which are armed with heavy horns. The skull consists of two tables or plates, half an inch or more apart, the outer thick and tough, the inner hard and brittle. These plates are connected by ridges of bone, which divide the space between them into compartments called sinuses. This, structure gives the skull exceeding strength and ability to resist blows and punctures by sharp substances. The bones of the head are joined together by sutures or dove-tails, which are also conducive to ex- treme strength. In this manner the brain is protected, and the horns are provided with a solid and elastic foundation. The form of the head is shown in figure 61, in which 1 is the occipital bone ; 2, parietal bone ; 3, core of right frontal bone ; 4, the left core covered by its horn ; 5, superciliary foramen ; 51, channel des- cending from it ; 6, lachrymal bones ; 7, zygoma ; 8, nasal bones ; 9, supermaxili- ary bones ; 10, premaxiliary bones ; 101, its internal process; 11, incisive opening. The cavity which contains the brain is less than a third the size of the rest of the skull, the larger portion being devoted to the functions of eating and smelling. The space devoted to mastication is large, and the space occupied by the nostrils, which are the breathing passages, rela- tively small. Most of the bones of the face are hollow, and are divided into sev- eral sinuses and cells by which the head is rendered light and strong. The sinuses and cells are lined with membranes which secrete mucus, and are therefore called mucous membranes. The inner cavity of the skull is lined with several membranes which still further add to its strength, and to the security of the brain. The teeth of the sheep consist of incisors or cutters, and molars or grinders. There are 8 of the former, all being upon the lower jaw, and 24 of the latter. Upon the upper jaw, in place of cutting teeth, the sheep has, in common with most of the ruminants, a cartilaginous plate or cushion, upon which the teeth of the lower jaw impinge when the mouth is closed. The sheep has no canine teeth or tusks. There is a long space of the jaws on each side be- tween the incisors and molars, which is destitute of teeth. The milk teeth, or deciduous or temporary teeth of the sheep, are twenty in number; the eight incisors on the lower jaw, and three molar teeth on each side of both jaws or twelve in all. The two Fig. 61.— BONES OF A KAM'S HEAD. THE TEETH. 171 central front teeth appear either before or soon after birth, and in about three weeks after birth, the whole of the twenty temporary teeth appear. The first change in the teeth occurs at the age of three months, when the lamb cuts a permanent molar tooth. The next change, also occurs at the back of the mouth, when at nine months old, another, the second permanent molar tooth appears. At one year old the lamb has but eight permanent teeth, or two at the back of each side of each jaw. The age of fourteen months is marked by the appearance of two permanent incisor teeth at the center of the front of the jaw. In judging of the age of a sheep, the condition of the molars may be studied with advantage. If a sheep is certified to be not exceeding one year old, and the fifth molar, (the second permanent one, and the last one on each jaw), is found to be sharp on the edges and but slightly worn, the age may be regarded to be properly stated, even though the central pair of front teeth have already appeared. But if these teeth are well up and the last molar is ^ orn and smooth, and there is a space be- tween this tooth and the angle of the jaw, the sheep is certainly over a year old. The sixth molar tooth is in its place at the age of eighteen months, and this is the only test of this age of the sheep. The second pair of front teeth, one on each side of the first pair, appear at twenty-one months of age, and at two years are fully grown and stand well up from the gum and level with the first pair. After the sixth molar is cut, the three forward and temporary molars are replaced by permanent teeth, which are fully grown at the age of twenty-Seven months. At two years and a half the third pair of front teeth have become fully grown, although in some forward sheep of the quickly maturing breeds, these teeth may appear at two years of age. Generally they indi- cate an age of two years and a half. At the age of three years, in the Cotswolds and other forward breeds, the fourth and last pair of front teeth appear; but in other breeds they are not present until three and a quarter or three and a half years. The sheep is then what is known as " full mouthed." The following table of the periods of dentition will be found useful in determining the age of a sheep : At one month, 8 temporary front teeth and three temporary molars on each side of each jaw. At three months, a permanent molar is added to these three. At nine months, the second permanent molar appears. At fourteen months, two permanent incisors appear, (as a, a, fig. 62). At eighteen months, the third permanent molar appears. At twenty-one months, there are four permanent incisors, ( a,a, fig. 63). 172 THE SHEPHERD'S MAKUAL. At twenty-seven months, the temporary molars are changed, and per- manent ones appear. At thirty months, there are six permanent incisors, (a, a, fig. 64). At thirty-six to forty-two months, there are eight permanent inci- sors, (a, a, fig. 65). It has been decided in an English court of law, that a lamb be- comes a sheep when the first pair of permanent incisors have ap- Ct Fig. 62. Fig. 63. peared. When the mouth is full toothed, the sheep is considered as mature, or full grown, when the teeth begin to show signs of wear, the sheep is " aged." The composition of the bones of the sheep and of the marrow con tamed in their cavities differs in no respect from that of the bones and marrow of other domestic animals. Bone consists of animal matter and earthy salts ; usually in the following propor- tion, viz : phosphate of lime, 55 per cent ; carbonate of lime, 4 per cent ; phosphate of magnesia, 3 per cent ; soda, potash, and com- Fig, 64. Fig. 65. mon salt, (chloride of sodium), 3 per cent, and 35 per cent of gela- tine. These proportions differ to some extent with the kind of bone, its solidity, and the age and condition of the animal from which it is taken. The bones of the skeleton are joined together by means of cartilages, or ligaments, which form what are known as articulations. Where the bones move one upon another, their ends, or the parts brought in contact, are covered with cartilage. Every bone is enveloped in a highly sensitive lining or membrane called the periosteum. Although the bones seem to be solid and insensible matter, chiefly composed of earthy salts, yet they are highly sensitive, and are formed of tissue which is penetrated by THE STRUCTURE OF BONE. 173 an infinite number of minute canals known as the Haversian canals which are from y2oo to Vasooth of an inch in diameter. These canals are parallel to the length of the bone, and frequently communicate together, forming an intricate net-work, which may be seen when a section of the bone made lengthwise is highly magnified, as shown in figure 66. In a cross-section of the bone these canals appear as at fig. 67, being surrounded by concentric layers, a, through which radiating tubes, 5, of the minutest size, penetrate. The periosteum is a highly vascular and nervous membrane which covers the entire bone, except the cartilagi- nous surfaces which move upon each other at the joints. It connects the outer surface of the bones with the tendons, ligaments, and muscles. The marrow is a fatty, pulpy sub- stance, which fills the central canals and the spongy tissue of the bones. It is pink in color, and contains merely a trace of fat in young animals, but as age ad- vances, it becomes yellow and less solid, and contains 96 per cent of fat. The bones are penetrated and lined within and without with numerous arteries, veins, and nerves. Some of these arteries penetrate the bones by appropriate openings, and divide into branches which form a net- work that lines the inner surface of the bones, and another that penetrates the substance of the marrow. Other arteries penetrate the spongy portions of the bones, and others form a net-work which belongs to the periosteum, and which Fig. 66.— THE HAVERSIAN CANALS. O Fig. 67.— CROSS-SECTION OF BONE. enter the substance of the bones by means of the Haversian canals. Veins accompany these arteries, and are very numerous where the spongy tissue is abundant. Nerves are abundant in the marrow and the spongy tissue, but few in the compact tissue. Portions of the vertebra are remarkable for the numerous nerves they contain. By means of the arteries and 174 THE SHEPHEKD'S MANUAL. veins, the bones receive nutriment and means of growth or repair, and by means of the nerves they become sensitive. The skeleton or frame work is clothed with flesh or muscular tissue. The muscles consist of bundles of fibers which possess the power of contraction when excited by sensations communicated by the nerves. The muscles are very diversified in shape, some being spread out in fan shape, some being thick and bulky, and some long and thin. The fibers are intermingled with fat or with cellular membrane. It is in the abundance of the cells which con- tain the fat, and in the power to assimilate food to supply the fat, that a sheep of a good breed or character is distinguished from one of a poor or bad character. The abundance of fat cells both within and upon the surface of the muscles gives the soft mellow hand- ling which distinguishes an excellent mutton sheep. The muscles are either directly connected by the ends of their fibers to the peri- osteum or covering membrane of the bone, as in the scapula or shoulder blade ; or the ends are gathered together closely and in- terlaced with the stronger fibers of the tendons or ligaments which are attached to the bones. By the contraction of the fibers of the muscles and tendons, the movements of the joints are made. In the muscular portions of the sheep consists the whole value of the carcass to the butcher, and the whole art of the breeder and feeder of those heavy-bodied breeds, known as mutton sheep, is concentrated in the effort to increase the muscular development in those parts of the carcass, as the loins and legs, the meat of which is most highly valued. The muscles are enclosed hi the skin which forms the covering of the animal. The protecting coat of the animal grows upon the skin. This is either hair or wool, both being of similar construction and composition, differing only in form or degree of fineness and texture. The brain occupies the cavity of the skull, and is the central seat of sensation and intelligence. From it proceeds the spinal marrow, which is a continuation of the brain, and which occupies a cavity through the center of the spine or backbone, from the head to the tail. The brain is largely supplied with blood by means of the carotid arteries, and the jugular veins serve to return the blood from the brain to the heart and lungs. In the sheep the brain is very small as compared with the size of the body, its average weight being but 4£ ounces, while that of the dog is 6| ounces. This difference in the development of brain reasonably accounts for the superior intelligence of the shepherd dog, one of which easily controls and guides the movements of a thousand sheep. The nerves proceed from the brain and spinal cord, and pen) THE VITAL FUNCTIONS. 175 trate in a net- work of the most astonishing fineness to the remot- est portion of the body, every portion of which, however minute, being endowed by the nerves with the faculty of sensation. In the sheep there are forty pairs of nerves, ten of which proceed from the brain, and thirty from the spinal cord. Each of these has its plexus, or system of branches and net-work. The nerves con- sist of bundles of white filaments or threads. The different senses, sight, smell, hearing, taste, and touch, are supplied by the nerves, which proceed directly from the brain. Another important brain nerve is the par vagum, or pneumo-gastric nerve, which proceeds to the heart, lungs, stomach, liver, and the bronchial or breathing apparatus. It is this nerve which gives the breathing, circulating, and digestive organs their power of motion independent of the will. Any injury or disease of this nerve affects these vital func- tions, and its division or destruction occasions instant death. The spinal nerves convey both sensation and motion. The spinal cord of the sheep weighs one ounce and three-quarters. The vital functions of an animal are respiration, circulation, and digestion or nutrition. By the first the system is supplied with oxygen, which is one of the sources of animal heat and is the agent by which the blood is purified. By the second, the tissues or living structure of the animal are supplied with nutriment and relieved from dead and used up matter, and by the last the blood is replenished with fresh supplies of nutritive elements. Respiration commences at the moment of birth and continues to the moment of death. It consists of an inspiration or in-drawing and an expiration or out-forcing of air. The motions necessary to these alternate actions are made by the diaphragm, a membrane which divides the chest from the abdomen. When this membrane is relaxed it is convex or rounded towards the chest. "When its fibers contract, it is straightened or flattened, and of course en- larges the cavity of the chest and causes a rush of air to fill the enlarged space. This alternate contraction and relaxing of the muscles of the diaphragm cause the motion of the chest, which is observed in breathing. A corresponding movement is also made in the abdomen, as may be noticed in the flanks of hard driven animals. The lungs occupy the largest portion of the cavity of the chest, and enfold the heart. They are two in number, the left and the right ; the left lung is divided into two parts, called lobes ; the right is divided into four lobes, of which one is curved around the heart. Fig. 68 shows this peculiarity, 1, 1, being the right lung ; 2, 2, the left : 3, the trachea or windpipe ; 4, the heart ; 5, the carotid arteries ; and 6, the vena cava, or great vein which 176 THE SHEPHESD'S MANUAL. carries the blood which has circulated through the body to the heart, from which it is forced to the lungs for purification. The lungs are composed of a spongy, highly elastic mass of cells. "When the cavity of the chest is enlarged by the contraction of the diaphragm, this elastic mass swells and fills the cavity. The cells enlarge, and vacuums are formed in them to fill which a stream of air is immediately directed. The air rushes through the nostrils into the trachea or windpipe, and thence into the bronchial tubes, which penetrate the mass of the lungs in all direc- tions, as the branches and twigs of a tree. By these bronchial tubes, air is carried into every portion of the lungs, where it meets the blood brought thither from every extremity of the body by means of the vena cava through the heart. In this contact the blood, loaded with impurities, and deprived of the oxygen which is needed for the support of the body, parts with its load of offensive matter, and takes up from the air whatever oxygen it requires to re- store it to a state of purity, and to enable it to fulfill the functions of circulation once more. The air having performed this office, is expelled from the lungs by the relaxing of the muscles of the diaphragm, and is expired. The expired air is highly charged with carbonic acid and vapor of water, nearly the whole of its oxygen having been absorbed by the blood. It is also charged with other products of the constant decomposition or waste of the tissues of the body, or of unnecessary matters which have entered the circulation through the digestive organs. Circulation consists in the constant motion of the blood from the heart through the arteries to the inner and outer surface of the body, and through every tissue of which the body is composed ; thence back by the veins to the heart ; thence to the lungs, where it is purified and fitted to again serve for the nutrition of the body ; it is then sent from the lungs to the heart to start again upon its round to the extremities. The blood is the most important part in the system of an animal. It consists of a white fluid colored red by very small globules, Fig. 68.— THE LUNGS EN- VELOPING THE HEART. THE CIRCULATION OF THE BLOOD. 177 called the blood corpuscles. From the blood the tissues of the body derive materials for their nutrition, growth, or repair, and for their secretions. The blood is replenished with new matter from the digestive organs, which dissolve and prepare the food for this purpose. To carry on circulation, an apparatus is pro- vided which consists of the heart, the arteries, the capillaries which form the connecting link between the extremities of the smallest branches of the arteries and those of the veins; the veins; the ar- teries of the lungs ; the lungs with their capillaries, and the veins of the lungs. There is thus a double circulation as it were, which may be readily understood by a reference to the diagram, fig. 69, in which C I) represents the left auricle of the heart, which forces the blood through the arteries E, in the direction of the arrows to the fine net- work of the capillaries; then to the veins F, and Fig. 69.— DIAGRAM OF THE oiEOULATioN. thence to the right auricle of the heart, A B. From this it is forced through the right ventricle which opens from the right auricle into the pulmonary artery G, still following the course indicated by the arrows, into the net-work of the capillaries of the lungs, from which it is conveyed by the pulmonary vein Ht into the left ventricle, whence it passes to the left auricle, on the same course over again. The heart is a mass of very strong muscular fiber, having the four cavities just mentioned, and being supplied with valves which regulate the flow of the blood. The muscles of the heart contract and expand with regularity, performing what we usually term its " beats," four times or thereabouts for every inspiration of the lungs. In a young sheep the heart beats 80 to 90 times in a minute ; a full grown one, 70 to 80 times, and in a very old one, 55 to 60 times. At each contraction the blood is forced through the arteries and their branches to the capillaries. These capillaries are exceedingly small, being from y20oo to Yseooth part of an inch hi diameter, and inosculate or join together again and again, forming a net-work of the closest character, so close that the finest needle cannot penetrate the skin or membranes any- where without wounding one or more of them, and causing an escape of blood. While circulating in this net- work of capillaries, the blood gives up to the tissues amongst which it circulates, the materials needed for their growth and increase, and also to sup- 178 THE SHEPHERD'S MANUAL. ply the waste of matter caused by every mechanical movement of the animal; for every contraction of the fibers of the muscles causes a decomposition and destruction of some portion of their substance. Hence is explained the waste of matter or loss of weight caused by excessive exertion or insufficient food. Here the blood also absorbs the dead, used up matter created by this de- composition and destruction of tissue, and carries it off from the system. This it does by means of the skin, the kidneys, and the lungs, through which the blood is filtered as it were of matters useless to the system by means of these capillaries ; and the excre- tions of perspiration both sensible and insensible, that of the urine, with some others, are thus thrown off. In this manner the blood becomes depleted of its nutritive properties, and absorbs the wastes of the system in its intricate course through these infinitely small capillaries. It enters them from the arteries a bright red, and leaves them a dark, blackish purple fluid. It courses onwards through the veins loaded with impurities, to the lungs, which it enters still a dark fluid ; here it passes through a second set of capillaries much finer than the former, in which it is exposed to pure air contained in the cells of the lungs ; the carbonaceous mat- ters it contains come in contact with the oxygen of the air, and are decomposed, burned in fact, giving forth the heat needed for the continuance of life ; when the blood thus rendered pure, leaves the lungs a bright red once more, again fitted to fulfill its func- tions. Before entering into the lungs, the blood receives a new supply of matter from the lymphatic vessels, called lymph, which is derived from the digested food. The vessel which conveys the lymph or chyle, is called the thoracic duct, and passes upwards into the cavity of the chest in close contact with the vertebrae or spine. The temperature of the blood of the healthy sheep is 100°. The blood is now believed to possess vitality ; while its circulation exists it is fluid, and when it is dead it coagulates. The cause of the coagulation of the blood is not known, and there is a difference between its coagulation in and out of the body. If a part of the body be wounded, the blood which escapes from the divided ves- sels, coagulates between the edges of the wound, forms a clot of organized material, throws out new vessels, and gradually restores the wounded parts. It is this coagulating property which saves the life of a wounded animal and directly leads to recovery ; if the blood remained fluid, the least wound would cause a flow which would not stop until the vessels were empty and the animal dead. The constituents of the blood are exactly those of flesh. Digestion is the process by which food is taken into the body, DIGESTION. 179 masticated, dissolved by the stomach and intestines, and rendered fit for absorption by the lacteals and lymphatics, and assimilation by the blood. The parts concerned in digestion are the lips, teeth, and tongue, the salivary glands, the gullet, the stomach, the intes- tines, the liver, the lacteals, and the thoracic duct which connects the digestive process with the direct function of circulation and nutrition. The lips are used by the sheep in gathering its food, very much as they are used by the horse, and to a much greater ex- tent than by the ox. The sheep's lips are thin, and very active in their movement. The upper lip is divided by a groove, or fissure, so that each half can be moved independently of the other. The sheep possesses no muffle or broad space between the nostrils on the upper lip, which in health secretes a liquid which appears in small drops upon its surface, as in the ox. The teeth have been already described. Their office is well known. The tongue serves to convey the food to the teeth, and from the teeth to the gullet, and also the cud from the gullet to the teeth. The salivary glands secrete a fluid which moistens the food during mastication, and which also possesses some of the character of a solvent, or a pre- paratory digestive agent, in being able to convert starch into solu- ble dextrine and sugar, and thus prepare it for digestion by the stomach. The glands are three in number, and are named the parotid, the submaxillary, and the sublingual. The first is situated at the outside of the angle of the lower jaw ; the second is placed on the inside of the lower jaw, near the angle ; and the third is beneath the tongue. Ducts from these glands give out the saliva naturally whenever the membranes of the mouth are excited by the presence of food ; or unduly, as in some diseases which cause an excessive secretion of the fluid. The gullet conveys food or drink from the mouth to the stomach. The pharynx is the upper part of the gullet, by which it is connected with the mouth. It is separated from the larynx, the entrance into the windpipe or air passage, by a cartilaginous lid called the epiglottis, which, when food is swallowed, closes the larynx and allows the food to slide over it. The pharynx, gullet, stomach and intestines, together form what is termed the alimentary canal. The gullet, also called the oesophagus, is a very strong, muscular tube, lined with insensi- ble white membrane. The fibers of the muscles run spirally around the tube, in opposite directions, and thus cross each other. By the contraction of these muscles, gradually extending down- wards, food is carried into the stomach ; while by their contrac- tion in an upward direction, the food is brought back to the mouth to be masticated the second time in the process of rumina- 180 THE SHEPHERD'S MANUAL. Fig. 70. — RIGHT SIDE OF THE STOMACH. tion. The food taken up by the lips and ^eeth is ground and mixed with saliva in the mouth, passed backwards by the action of the tongue to the gullet, and then forced into the stomach. The stomach of the sheep consists of a large irregular sac or pouch, divided into four compartments, generally referred to as distinct stomachs, or the first, second, third, and fourth stomachs, (see figs. 70, 71, and 72), or the rumen or paunch, seen at 6; the reticulurn or honey- comb, c ; the omasum or manyplies, d-, and the abomasum, or rennet, or true digestive stomach, e. The gul- let is seen at a, and the duodenum at /. The functions of the stomachs of the ruminating animals are known only somewhat obscurely. Anatomy only teaches their form and charac- ter, and leaves all the rest hi doubt, or to be decided by experiment and observation. From the structure of the stomachs we are able to form a generally complete idea of the process of digestion which goes on within them ; of some of the details there is nothing certain as yet to offer. The first two stomachs are placed parallel to each other, and the gullet ends almost equally in each, as seen at a in fig. 72, which shows the inside formation of the stomachs. The second stomach, c, communicates with the third by the oesophagean canal, g, which opens into the third stomach, (not seen in figs. 70 and 71), and ends there. The fourth stomach is connected with the third by a distinct opening. The paunch, &, is the largest compartment, being four times the capacity of the other three together. It is divided into four in- complete compartments by muscular walls, and is lined with a membrane covered by a multitude of soft pillars compressed closely together, which make an uneven surface. The second stomach, c, is lined with cells having five or six sides from which it takes the common name, the honeycomb. These two compartments, or stomachs, are in reality one, the latter being Fig. 71.— LEFT SIDE OF THE STOMACH. THE STOMACH. 181 simply an appendage of the former. The cesophagean canal which leads from the second stomach to the third, performs a very im- portant function in the act of rumi- nation, or it is supposed -with reason so to do, as will be explained further on. The third stomach or " manyplies," in the sheep the smallest of the stom- achs, is lined with a number of leaves or folds, placed lengthwise, by which the surface is greatly increased. The fourth stomach joins the third, and communicates with it by an opening immediately opposite to the O3sopha- gean orifice. The fourth stomach is lined with a membrane which secretes Fig. 72.— INTEKIOR OF THE the gastric juice, the true digestive STOMACH. solvent. It opens directly into the duodenum or small intestine. Rumination, or chewing the cud, is a process which distinguishes a class of animals, known as ruminants, from all others. For the performance of this process the complicated stomach above de- scribed is provided. To understand this important alimentary process, it is necessary to ascertain first, into which of the stom- achs the food passes after its first mastication ; second, in what manner and by what process the food is rejected by these stom- achs and returned to the mouth for a second mastication ; third, to which of the stomachs is the food finally transmitted for com- plete digestion. Some careful experiments, by the French physiologist, Flourens, have to a great extent determined these questions ; and the com- parative anatomist, Chauveau, has summed up the functions of the stomachs of ruminants as ascertained from every modern source of information as follows : 1st. The rumen is a sac in which the food swallowed during feeding time is held in reserve, and is softened, and whence it is ed to the mouth during rumination. The reticulum partakes of the functions of the rumen, to •which it\)lays the part of an accessory or reservoir ; the food con- tained hi it being always diluted by a larger quantitjr of water. 3rd. The czsophagean canal carries into the omasum the food swallowed the second time, or after rumination, or even those por- tions of food which the animal swallows in wry small quantity and in a finely divided or softened condition the first time. 182 THE SHEPHERD'S MANUAL. 4th. The omasum completes the maceration or reduction of the food to a sufficiently fine condition for digestion, by pressing it between its leaves. 5th. The abomasum is the true digestive stomach, and finally dissolves the food by its gastric secretion. In these processes the cesophagean canal performs a peculiar func- tion. The ordinary food of the ruminating animal is coarse in texture, aud when swallowed is bulky. When it enters into the stomach and meets the opening of the oesophagean canal, it forces open, by its bulk, the muscular lips of which the opening is com- posed, and drops partly into the first, and partly into the second stomach. M. Flourens has satisfied himself, by careful experi- ments upon a living sheep, that when the animal ruminates, a por- tion of the food swallowed previously and now contained in the first and second stomachs — which are really one— is forced by a contraction of the stomach into the oesophagean canal, and this then contracting, closes all the other openings except that of the gullet, and at the same time compresses the morsel of food into a pellet or ball, which is immediately forced by the upward muscular con- traction of the gullet into the mouth. When it has been chewed and mingled with the copious secretion of saliva which takes place during rumination, it is again swallowed. Being now softened and in a semi-liquid condition, it passes over the lips of the open- ing of the canal, without forcing them apart, into the second stomach, and enters the third stomach ; a small portion of it only escaping into the first and second stomachs. When fine or semi- liquid food is first swallowed, it follows exactly the same course, the same being true of water when drank. From the third stom- ach the food passes on to the fourth stomach to be finally disposed of. It has been found that the pellets of food, returned to the mouth for rumination, are of the precise size, shape, and form of the portion of the oesophagean canal between the first and third stomachs. Sheep have been dissected with these pellets ready formed in the canal for transmission to the mouth. The intestines of the sheep are of great length, being twenty- eight times longer than its body. In the duodenum, which is the upper portion of the intestines that directly communicates with the lower orifice of the stomach, the partially digested mass of food undergoes still further changes. As it passes from the stom- ach it is termed chyme. In the duodenum the chyme is mingled with the bile, which comes from the liver, and the pancreatic juice, a secretion of the pancreas, or " sweet-bread," and becomes fitted THE LIVER. 183 for absorption by the lacteals which communicate with the intes- tines. It is now termed chyle, and is a white milky fluid which enters the thoracic duct and mingles with the blood as previously described. The refuse and insoluble portion of the food, with un- used portions of the bile pass on through the lower intestines, and is discharged by the rectum as dung. The liver is a large organ with the appearance of which almost every person is familiar. It is called a gland, because its office is to secrete a fluid which is peculiar to it, and it is the largest gland in the body. Its secretion is called the bile. Its position in the body is below the diaphragm and adjacent to the stomachs, with the third of which it is in direct contact. It is enveloped in the peritoneum or membrane which covers and also encloses the whole of the contents of the abdomen, and forms as it were a sac or bag, one-half of which is doubled into the other half. The liver hi sub- stance is granular, consisting of grains, or lobules, from one-tenth to one-twentieth of an inch in diameter. Its color is reddish brown. The lobules of which it is composed are closely packed, and are held together by fine tissue and a net-work of minute veins and ducts. Each lobule is connected with a blood vessel at its base, and another vessel comes from the center of the lobule and joins the former one at its base. Between these two is an exceedingly fine net-work of capillary vessels similar to those pre- viously described. By means of arteries and veins called portal canals, which enter and ramify through the substance of the liver, the blood is carried into and through the substance of each lobule in streams of exceeding fineness. From the blood thus passing through the lobules, the gall or bile is secreted by small cells not ex- ceeding Vioooth of an inch in diameter, and is collected into minute vessels called biliary ducts, from which it is gathered into larger ducts, which pour their contents into the great bile ducts. There is a receptacle in the liver of the sheep known as the gall-bladder, to which the gall is carried from the hepatic duct by another duct named the cystic duct. When the gall contained in the gall-blad- der is required for use, it returns by the same duct into the hepatic duct, and thence into the great bile duct which ends in the duo- denum, below the stomach. The gall is an alkaline fluid of composite character, containing soda, two peculiar acids, (glycocholic and taurocholic, the latter of which contains sulphur) ; mucus ; cholesterine ; stearic, oleic, and lactic acids, with potash and ammonia, and a peculiar coloring matter. It is in fact a sort of liquid soap. The bile is poured into the duodenum by the great bile duct. Near this duct is 18-4 THE SHEPHERD'S MANUAL. another from which flows the secretion of the pancreas or sweet-bread. This fluid is slightly alkaline and very similar to the saliva. Its office is supposed to be to change the un dissolved starch in the chyme into sugar, and to form an emulsion with the oil or fat of the food, and prepare it for absorption directly into the blood or into the lacteals. The office of the gall is to neutral- ize the acidity of the chyme derived from the gastric juice, which is an acid fluid, to assist in the transformation of starch into su- gar, and the absorption of oil or fat. It is the chief agent in changing the chyme of the stomach into the chyle, which is the perfected source of nutrition of the blood. The perfect action of the liver is therefore absolutely necessary to the sustenance and the life of the animal. The quantity of gall secreted by the liver of the sheep every twenty-four hours is from 3 to 5 pounds. The whole of this, however, is not destroyed in the performance of its office, but a large portion is taken into the system in the circula- tion, the surplus being regained from the blood by the secreting cells of the liver and again returned for duty to the intestines. Another office of the liver is to prepare crude albuminous matter of the blood for final absorption into it. It is also able to form sugar from other carbonaceous matters conveyed to it in the chyle absorbed by the lacteal vessels. Thus the liver acts as a filter, in separating detrimental matters from the blood, besides supplying a necessary agent in digestion, as well as for respiration. Its im- portance in the animal functions cannot be over-estimated. The lacteals are a series of small absorbent vessels which form a net-work in connection with the coats of the intestines, and pro- ceed to the thoracic duct, where they terminate. They exist much more numerously in connection with the small intestines than with the lower ones. Their chief seat is the mesentery, which is the thin membrane which supports the small intestines. The lac- teals enter the numerous glands of the mesentery, and pass through them, uniting to form larger vessels and becoming fewer and fewer in number, being finally reduced to two or three ducts which end in the thoracic duct. The lacteals absorb the chyle, which is presented to them in the intestines, convey it to the glands In which it is enriched and perfected, and thence convey it to the vessels which terminate in the duct from which the new nutri- tive matter is poured into the large vein near its junction with the heart, to enter into the circulation. The chyle is very similar in its composition to the blood, differ- ing from it chiefly in the absence of coloring matter, or the red globules which give the color to the blood. It coagulates on THE EXCBETORY ORGAN'S. 185 being allowed to rest, although the clot is softer than that of the blood. The thoracic duct extends from the loins to the neck, and its course is along the spine. It is the principal trunk of the absorb- ent system, and, as has been explained, is the connecting link be- tween the digestive organs and the circulatory system, as the pul- monary artery and vein is the connecting link between the circu- latory and respiratory system. 2Jie spleenis another organ which is very important, as being the seat of a rather obscurely understood disease, known as splenic apoplexy. It consists of a spongy mass of tissue of a mottled blue or purplish gray color. It is suspended near the great curvature of the stomach, but of its functions nothing is precisely known. It is supposed to act as a reservoir of blood for the portal vein ; it is also supposed to destroy the red globules of the blood, as it has been discovered to contain blood globules in a state of decom- position. It is, however, known that, in the course of researches to discover the uses of this gland, animals from which it has been removed have recovered from the operation, and have continued to live in apparent good health. The fact of its engorgement with blood in the disease of ruminants known as splenic fever or apoplexy, and its increase of volume in certain bilious disorders, would tend to show that its functions are in some way closely connected with the circulation, and perhaps with the digestive processes and nutrition. The Urinary or Excretory Organs. — The urine is separated from the arterial blood by the kidneys. These organs, with the liver and the lungs, are employed in the purification of the blood. The liver separates compounds abounding in hydrogen, the lungs those which abound in carbon, and the kidneys those abounding in ni- trogen. The nitrogen eliminated through the kidneys exists in the form of urea, a crystalline substance which readily decomposes and gives off its nitrogen in the form of ammonia. There are two kidneys, one each side of the spinal column. The kidneys are attached firmly to the loins ; in the sheep they are shaped like a bean, and are imbedded in fat. They perform a double office, or two separate functions, one being to discharge from the blood any excess of water that may accumulate in it ; the other being to rid the blood of excess of saline matter and the products that result from the waste of the tissues. The blood enters the kidneys by arteries, and the urine, separated as by a filter, through a very com- plex system of capillaries, flows into two white ducts termed ure- ters, which pass it onwards to the bladder. The urine of the 186 THE SHEPHERD'S HAKUAL. sheep is not so copious as that of the cow in proportion to its size, but possesses a larger proportion of salts. The following is an analysis of sheep's urine : Water 96.0 per cent. Urea with some albuminoids and coloring matter 2.8 " " Salts of potash, soda, lime, magnesia, silica, iron, alumina, and manganese T . . 1.2 " " 100.00 " In fig. 73 is shown a section of the substance of the kidney highly magnified, in which appear the uriniferous, (urine carrying) ducts or tubes, (a, a), surrounded by the secreting glandular sub- stance, (&, &), which is enclosed in the net-work of the arteries, (c, c), and the fibrous tissue, (tf, d). The bladder is situated hi the pelvic cavity, or the lower part of the abdomen. It is composed of two coats, the outer one being muscular, and capable of contracting so as to expel its contents. One half is enveloped in a third coat, and the other half in the /, tissue of the pelvic 0 . n «••'••- region, and masses of fatty matter. The mus- cular coat consists of fibers Placed in various directions, lengthwise, crosswise, oblique, and spiral, so that in the act of contraction the blad- der is reduced in size Fig. 73.— STBUCTUBB OF THE KIDNEY. evenly and in every direction. A strong muscle encircles the opening, from which the urine is discharged, and which is called the neck of the bladder. The contraction of this muscle closes the neck and retains the contents, its relaxation opens the orifice and Callows the contents to be ex- pelled. From the neck of the bladder proceeds the urethra, by which the urine is discharged. In the ewe the urethra is very short, in the ram it is much longer, and passes down from the anus along the abdomen to the extremity of the penis. The func- tions of the bladder are very important. It serves as a reservoir for the urinal fluid which is constantly secreted by the kidneys and retains it until a considerable quantity has been accumulated, and thus spares the animal from otherwise continually dribbling away the urine as it is secreted. The Eeproductive Organs. — These are entirely different in the THE REPRODUCTIVE ORGANS. 187 male and female. The female organs are more abundantly devel- oped than those of the male, and have more intricate functions to fulfill. They consist of two secreting organs called ovaries, which are charged with the elaboration of the ovum or egg ; the uterine tube through which the ovum passes on leaving the ovary; the uterus or womb in which it rests after its impregnation, and in which it remains until it is fully developed ; and the vagina or canal through which the foetus or young animal when perfected is discharged. In addition there are two mammas or milk-producing glands enclosed in the skin, and attached to the lower part of the abdomen and inner parts of the thighs, each of which has a set of secreting glands and milk ducts flowing into a tube which has its orifice in the teat. These milk glands are called the udder. The ovum is a cell about Viooth of an inch in di- ameter, which is contained in another cell or ovisac, of which the ovaries contain a certain number. At stated periods called the oestrum or condition of " heat," the ovaries become excited and distended, and discharge one (or more) of these ovisacs, which, par- taking of the condition of the ovaries, becomes distended and bursts, releasing the ovum, which, when it is brought into contact with the impregnating fluid of the male in the uterine tube, undergoes a change, enters into the uterus, and hi course of time becomes a living animal. When the female is not brought into connection with the male at the season of heat, the ovum undergoes no change, but passes on to the uterus, where it is absorbed. The impregna- ted ovum, when it reaches the uterus, becomes grafted upon its lining membrane and draws directly from the mother's blood the materials for its development. In the male the reproductive organs consist of two glands, which in the ram are suspended in a sac between the thighs. This sac is called the scrotum. The glands, called the testicles or testes, are each enclosed in four envelopes, being separate and distinct from each other. One of these envelopes is a portion of the peritoneum or lining of the abdomen, which descends through an opening in the abdomen. This opening remains afterwards, and it is thus that in castrating the ram, the inflammation which often takes place, spreads into the abdomen and destroys the animal. The glands are oval in shape, and consist of a grayish pulp. They are attached to the spermatic cord and artery, and their function is to secrete the spermatic or impregnating fluid, which is alkaline, and contains minute filaments not larger than YBOOO to Vsoooth of an inch in length. These filaments possess the power of independent movement for some days after their expulsion from the organs of 188 THE SHEPHERD'S MANUAL. the male. A canal or duct called the 'Das deferens, leads from the testes to the outward and exposed male organ. In the ram this organ has at its extremity a small spiral appendage called the vermiform, (or worm-like), appendage. This has a very narrow orifice, and is often on this account the seat of obstructions which are difficult to remove. The testicles of the ram are very large in proportion to its size, and the whole reproductive powers are highly vigorous, enabling him, when well nourished, to serve effectively a hundred ewes in a season. OBSERVATIONS ON THE DISEASES OF THE SHEEP. In judging of the symptoms of disease in the sheep, it is neces- sary to take into account the nature, constitution, and habits of this animal. The diseases of the sheep are numerous and more generally fatal than those of other domestic animals. The diges- tive organs of the sheep are largely and powerfully developed, and its capacity for the production of blood is very great. Yet its needs for this large supply of blood is not to support its nervous system, which is feebly developed, nor its muscular exertion, of which it is incapable to any great extent, nor its circulation, which is onty of inferior amount, but the surplus must necessarily go to the production of flesh, fat, and wool. In the sheep, therefore, the production of flesh, fat, and wool, is the chief of its functions, and the greater part of its vitality is expended in this way, leaving but a small amount to sustain the comparatively weak vascular system. The sheep is unable to sustain severe muscular labor ; and slow movement, except for very limited periods, is all that it is capable of. From the small brain development of the sheep, its weak nervous and circulating system, it is to a great extent free from diseases of an inflammatory character. From the large exercise of its digestive powers, it is to be expected that diseases of the di- gestive organs should be frequent and serious, and this we find to be the case. From the same causes that render it compara- tively free from diseases of an irritating character, it with more than usual readiness succumbs to those in which debility and the exhaustive effects of parasites are the chief features. Indeed it is to the attacks of parasites, both external and internal, that sheep owe their most troublesome and fatal disorders. Infectious or contagious diseases have greater scope for action amongst sheep than amongst other domestic animals, by reason of their gathering together in large flocks, and thus being more exposed to unwhole- THE DISEASES OF SHEEP. 189 some influences than those animals which are usually kept singly, or which when kept in large numbers, naturally break up into small separate herds. The structure of the foot, and the manner of the growth of the crust and sole are such as to subject it to dis- ease in that organ from which other animals are free. In the management of a flock of sheep, it is necessary to bear in mind the peculiarities and habits, so that the watchful care of the shepherd may be given as far as possible to exercise precautions which may prevent disease. Fortunately our climate is so well adapted to these peculiarities and habits, that our flocks suffer from far fewer diseases than those of other less favorable climates, and at present many diseases prevalent in other countries are unknown to us ex- cept by report. Precautions to be effective must be intelligently exercised, and it is only by thoroughly understanding his flock that the shepherd can know what to avoid and what to do. The symptoms which indicate approaching disease should be instantly recognized, or the threatened danger cannot be averted. Then the timely remedy may be employed, which is rarely ineffective, while that which comes later is rarely serviceable or effective. The remedies to be administered must be consistent with the peculiar- ities of the sheep. Possessing but a weak vascular and nervous system, and a small supply of circulating blood, bleeding is rarely called for, and can be employed only with danger of doing harm in place of good. For the same reason tonic and stimulating med- icines are more frequently needed, and may be given in larger doses. Purgatives, especially saline ones, for the same reason, always demand an accompanying: stimulant. Purgatives are frequently called for, as the digestive organs so abundantly developed and largely exercised, are readily dis- eased or disordered, and disturbance of the system rarely occurs without sympathetically or otherwise involving those organs. The veterinarian used to study the diseases of the horse, and to apply his reasoning to the peculiarities of that animal, is too apt to lose sight of the vast surface of the stomachs of the sheep, the in- sensibility of much of this surface, and the fact that medicine ad- ministered with the food or in solid form, will most probably fall into the rumen, where it will be ineffective. So too the shepherd, who consults veterinary works, will be misled to a great extent, and be induced to believe the too common idea that it is folly to physic a sheep, and the best treatment is to cut its throat at once. In treating sheep, purgatives are useful to reduce fever, to lower inflammation, and to restore tone to the stomach and liver. They should always be given in a liquid form. Of all the purgatives, 190 THE SHEPHERD'S MANUAL. Epsom Salts and Linseed Oil (always raw) are the most suitable and effective. The action of stimulants given along with a purga- tive is always beneficial. Stimulants, of which Ginger, Gentian, Aniseed, and Pepper- mint-oil are the most usual and useful, restore the tone of the stomachs and excite them to action, thus aiding hi the operation of the purgative, which might otherwise still further enfeeble them. Bleeding, when it is necessary in the outset of inflammatory dis- orders or local excitements, should be performed by operating on the veins under the eye (see fig. 76) or the ear ; the inside of the fore arm is a convenient place ; when a large quantity is to be taken, the jugular vein of the neck may be opened by first cut- ting off some of the wool, pressing the vein with the finger, and cutting it lengthwise — never crosswise — with a sharp lancet. Never less than two ounces or a wine-glassf ul should be taken, and rarely more than half a pint. In referring to the diseases hereinafter treated of, as far as possible, the causes to which they may generally be attributed, with the means of prevention, will be given. The remedies men- tioned will be those to be given to a full-grown animal, for lambs, one-half or less of the doses should be given, and for very young lambs, still less should be given. The most prolific causes of disease are over-feeding, under-feed- ing, irregularity of feeding, want of water, drinking impure water, impure air, damp, and over-driving. If these were avoided there would be but little complaint of the frequent troubles, difficulties, and losses in keeping sheep. While they exist, medicine, at the best, is but a temporary expedient, effective only during the time in which extra care is used. When this care is allowed to relapse the trouble will infallibly recur. CAUSES, PREVENTION, AND TREATMENT, OF DISEASES COMMON TO SHEEP. DISEASES OF THE RESPIRATORY ORGANS. Catarrh is very common during the fall, winter, and spring. It will be found on close observation to be rarely absent in any flock. In our diy climate, subject, however, to sudden changes of temper- ature, catarrh, or cold, is mostly due to exposure to damp hi open yards, or to too high a temperature in sheds or pens, rather than to exposure to the weather in open fields. Flocks that are more care- DISEASES OF THE LUNGS. 191 fully tended and housed than usual, are found to be more subject to it than others. Of two flocks equally well fed, but one of which is carefully shut up every night and protected (?) from every draft of fresh air, and another whose bed is the snow in an open, airy, dry yard, it will be the first that will be troubled with cough and discharge from the nose, while the latter will be free from it. Fresh air, ample ventilation in partly open sheds, dry yards and clean, dry bedding, and protection from chilling rain-storms in winter, with whatever protection may be needed immediately after shearing, should the weather be cold and rainy, will generally be amply sufficient to prevent any trouble from this complaint. Chas- ing by dogs and consequent over-heating, and over-driving, are certain causes, and these should be carefully avoided. The judg- ment of the shepherd should be exercised in exceptional cases, act- ing always under the general rule that dry cold is rarely hurtful to sheep, while they suffer from wet or damp cold, and that moist, warm, steamy, close atmosphere, especially when confined in sta- bles, will inevitably produce cold or catarrh, which if not at once remedied will generally result in serious disorders of the lungs. This disease consists of inflammation of the lining membrane of the throat, windpipe, nostrils, and the sinuses of the head. It produces an increase of the secretion of mucus and consequent ir- ritation and coughing. When long continued, the cough becomes dry and deep seated, showing that the lungs are involved. The treatment consists in removal of the causes, good nursing, ad- ministering slightly warm mucilaginous drinks, as oat-meal gruel or linseed tea, along with a gentle stimulant, such as half a teaspoonful of ground ginger. The antiseptic effect of a small quantity of clean pine tar rubbed upon the sheep's nose, some of which the animal will lick off and swallow, will be beneficial. If there is fever, and the nose is dry and hot, the following may be given, viz : Epsom Salts !/a ounce. Saltpeter 1 dram. Ground Ginger 1 dram. This should be mixed with molasses and placed on the back part of the tongue with a long, narrow bladed wooden knife or spatula. The animal's head should be held up until the whole is swallowed in repeated small quantities. Or the dose may be mixed with thin gruel and administered by means of a small horn. Bronchitis is simply a deep-seated catarrh which affects the bron- chial tubes or air passages in the body of the lungs. It is danger- ous, inasmuch as the inflammation readily spreads and affects the lungs. In bronchitis the cough is more severe than in catarrh, 192 THE SHEPHERD'S MANUAL. the pulse and the respiration are both quickened, there is some fever, and the appetite fails. The treatment is the same as that prescribed for catarrh, but to be continued longer, changing the dose to the following, to be administered for three or four days, reducing the quantity of saltpeter gradually one-half. Linseed-oil 1 ounce. Saltpeter 1 dram. Powdered Gentian 1 dram. Bleeding must not be attempted in this disease. Quietness is in- dispensable, and a clean, airy, but solitary, pen should be provided, and a plenty of pure, fresh water supplied. Pneumonia or Inflammation of the Lungs. — This is a more fre- quent disease than is generally suspected. Many sheep exhibit the peculiar symptoms of pneumonia, and are too far gone for re- covery before their too careless owners are aware that they are affected. High-bred imported sheep, the Leicester more particu- larly, are very liable to this disease, which is generally fatal to them. It consists of inflammation of the substance of the lungs, and frequently follows neglected attacks of bronchitis, the inflam- mation easily and quickly passing from the lining membrane of the air-passages to the cellular tissue of the lungs. Washing in streams of cold spring water, or sudden chills from exposure to cold showers, quickly succeeding hot weather, or when heated with driving, or after shearing, or too close penning in warm stables in cold weather, are the usual causes. It is rarely that this disease develops fully without previously passing through the earlier stages, or without some serious mistake in the management of the sheep ; and it is only by instant attention and proper treatment that its usually rapid and fatal course can be arrested. The symptoms are a quick and labored breathing with painful heaving of the flanks ; a painful cough ; discharge of thick yellow mucus from the nostrils, high fever, and great thirst ; hard, quick pulse ; constant grinding of the teeth, together with loss of appe- tite and rumination. On examination after death, the lungs are found to be hard and gorged with blood, and if thrown into water they sink to the bottom. The disease usually terminates in death in from twenty -four to thirty-six hours. Treatment is of no avail unless commenced immediately. Bleed- ing from the jugular vein, until the animal staggers, is the first and most effective remedy. If found necessary, this should be repeated in six hours. Two ounces of Epsom salts should be given imme- diately after the bleeding ; if this does not cause free purging, one ounce more may be given in three hours. Copious purging is not DISEASES OF THE LUNGS. 193 to be dreaded in this disease with sheep as with the horse. Injec- tions of thin oat-meal gruel, strained, should be given every two hours. After the bowels have been well evacuated, the following may be given twice a day in oat-meal or linseed gruel : Powdered Digitalis 1 scruple. Nitrate of Potash 1 dram. Tartar emetic 1 scruple. to be continued several days. As soon as the sheep improves and begins to move about, a pint of gruel may be given every three hours with half a dram of powdered Gentian. Warm drinks of dissolved gum Arabic, or linseed-meal tea, hi which a little honey is dissolved, will be useful. The nostrils should be freed from accumulated mucus by washing or sponging with a mixture of equal parts vinegar and water, or of one ounce of acetic acid with a quart of water. Some of the acidulated water should be squeezed into the nostrils to clear them as far as possible. One dram doses of tartar emetic alone have been given with benefit in this disease. As it is in nearly every case avoidable by proper care and precaution, and is rarely cured when once well seated, it will be by far the best policy to prevent its occurrence. Pleurisy, or inflammation of the membrane covering the lungs and the lining of the cavity of the chest, is produced by the same causes as pneumonia. It frequently accompanies this latter dis- ease. It most frequently follows the careless washing of sheep or their exposure to cold winds with wet fleeces, or from a severe chill after having been sheared. After an attack of this disease, and a seeming recovery, an adhesion of the lungs to the sides of the chest often takes place which prevents the sheep from thriving and keeps them in poor condition, from which they cannot be recovered. Wide-spread causes, chiefly those arising from the un- favorable condition of the weather, sometimes affect the flocks of extensive districts, and lead to the supposition that the disease is epizootic or contagious. This, however, is not the case. Prevention consists in watchful care to protect the sheep from sudden change of the weather at a time when they are more than usually exposed to its ill effects ; also from a too sudden change from housing to open pasturing in the spring. All sudden changes in the management of sheep should be made with caution, a change, even from poor to rich feed, may produce this or other in- flammatory diseases, and care must be exercised in this respect. The symptoms are similar to those of inflammation of the lungs ; more pain is experienced, and the sheep exhibits more distress, sometimes moaning in agony. After death, the cavity of the chest 9 194 THE SHEPHERD'S MANUAL. is found filled with fluid ; the surface of the lungs is highly in- flamed, and covered with livid patches, but their substance is not affected. Generally no trace of disease is found elsewhere. The treatment consists in copious bleeding as for pneumonia, but more blood may be taken with benefit. The following may be given : Powdered Digitalis .............................. 1 scruple. Nitrate of Potash ................................ 1 dram. Nitrous Ether, (Spirits of Nitre) .................. 3 drams. to be administered in linseed-meal or oat-meal gruel twice a day for four or five days. When recovery be- gins, the following tonic may be substituted : Sulphate of Iron .................... ya dram. Infusion of Quassia or Chamomile.^ pint. dram. Ground Ginger i/fl If the animal is valuable, it may sometimes be saved after the effusion of serum in the chest has occurred to a considerable extent, by tapping the cavity with a trochar and canula, (fig. 74), and drawing off the fluid. When this effusion has taken place, it may . be discovered by tapping the sides of the chest, when a dull dead sound only is heard ; also by a gurgling sound during expiration, which is painful and difficult. The trochar is inserted cautiously between the eighth and ninth ribs, and the canula left in the opening through which the fluid flows. Generous feed- ing and great care are needed after tapping. DISEASES OF THE DIGESTIVE ORGANS. Choking. — Sheep are not often troubled with obstructions of the gullet, except when fed upon cut or sliced turnips, or permitted to consume the shells of turnips which have been scooped out by them in the field. When a sheep is thus choked, the head is held down, saliva flows from the mouth, breath- ing is difficult, and the stomach becomes dis- tended with gas, or air swallowed in the ef- forts to dislodge the obstruction. When this occurs, the sheep's head should be raised and held firmly between one man's legs, £. 74. — TKOCHAR AND CANULA. COSTIVENESS. 195 while another pours a teaspoonful of linseed oil or melted lard down the throat and endeavors by gently manipulating the gullet to work the obstruction downwards. If this is ineffectual, a pro- bang should be used. This is a flexible thin rod, as the wash rod of a rifle, or a piece of light rattan or other tough elastic material. A soft ball of tow, or of strips of linen cloth is securely fastened to the end of the rod. This is well soaked with sweet oil or lard, and gently inserted into the gullet until it meets the obstruction, when it is to be forced downwards without violence, a few gentle, but smart taps on the upper end with a light stick being generally more effective than continuous pressure. If the lining of the gul- let is injured in the operation, and the sheep refuses to eat, gruel or other liquid food should be given until the soreness disappears. If the obstruction cannot be removed in this way, the sheep had better be slaughtered. If it is a valuable animal, an effort which is frequently successful, may be made to save it by cutting open the skin and the gullet upon the obstruction, and removing it. The opening in the gullet is then closed by a stitch made with a sur- geon's curved needle, and the wound in the skin closed separately in the same manner. The sheep should be securely held during this operation. Soft food should be given until the wound is healed. (See Treatment of Wounds). Costiveness — Stretches. — This complaint is more frequently a symptom of disease than a disease itself. Yet it frequently occurs when changing the flock from pasture to dry food. The dung then becomes dry, hard, and scanty, and is discharged irregularly. The termination of the bowel is red and inflamed, and when void- ing dung, the sheep grunts or moans as with pain. Care in chang- ing the food is a preventive, and a few ounces of linseed-cake-meal daily will obviate the difficulty. Injections of warm soap and water, or of one ounce of linseed-oil, will relieve the bowels, and one ounce of linseed-oil given by the mouth will generally bring about a cure. When the costiveness is of long continuance, from neglect, the sheep may be perceived stretching itself, spreading the feet apart, raising the head, curving the back, and extending the abdomen. This may also occur from obstruction of the bowels, which, how- ever, is rare with sheep, but is most frequently caused by costive- ness. A teaspoonful of Sublimed Sulphur, (Flowers of Sulphur), mixed with a small quantity of molasses or lard, may be placed on the tongue to be swallowed, once a day, for a week. A regular allowance of a mixture of four ounces of Sulphur with one pound 196 THE SHEPHERD'S MANUAL. of salt, placed where the sheep can have access to it at will, is a sure preventive of costiveness. DiarrTiea or Scours. — A looseness of the bowels, without pain, fever, or other complications, frequently occurs when sheep are turned to pasture in the spring, or turned on to rich succulent green food, as clover, rape, or turnips. It is sometimes perceived when they are exposed to the hot sun in early spring without shelter. It is not dangerous of itself, but as the disease very quickly interferes with the process of nutrition, the blood is soon affected, and the more serious blood disorder, dysentery, super- venes. Diarrhea may generally be prevented by careful regula- tion of the food, and avoiding sudden changes, and the regular supply of salt. It is quickly subject to proper treatment, which consists of the administration of astringents and cordial prepara- tions. The following mixture should always be kept on hand by the shepherd, ready for instant use : Prepared Chalk 1 ounce. " Catechu 4 drams. " Ginger 2 " Opium Va 4 to be mixed with half a pint of peppermint water and bottled for use. Two large tablespoonf uls of this is given night and morning to a sheep, and half as much to a lamb, always previously shaking the mixture well. Cotton-seed-cake-meal is both an excellent pre- ventive and remedy for this complaint, and a supply should be kept for use. Half a pound a day should be given to a sheep. If any mucus or glutinous substance appears in the dung it is a proof of the existence of irritating matter in the intestines, and a laxative should be given previously to the above. This may be Linseed-oil 2 ounces. Powdered Ginger 1 dram. OK Epsom Salts 1 ounce. Ginger i/a dram. Gentian i/2 dram. to be given in infusion of linseed-meal. Hoven, or distension of the rumen, is not uncommon in sheep. It consists in the formation of gas in the first stomach, or rumen, by which it is so much distended as to press injuriously upon the diaphragm or membrane which encloses the chest. This prevent- ing the contraction of the diaphragm interferes with the respira- tion. It appears as an enlargement of the left side of the abdomen, by which the skin is tightly drawn until in apparent danger of BLOATING. 197 bursting. It is caused by the rapid fermentation in the stomach of very succulent green food, which has been greedily swallowed while wet with dew or rain. The stomach may at the time be disordered, and its digestive powers impaired ; or the distension may be produced by other diseases of which it is an attendant or a symptom. In such a case it indicates a decrease or chemical change of the alkaline secretions of the rumen. The treatment should be immediate, lest suffocation ensue. An alkaline fluid poured into the rumen, frequently alleviates the symptoms and removes the trouble. This may be Ammonia Water (Aqua Ammonice) 1 teaspoonful Water Va pint. to be administered through a horn. A hollow, flexible probang, which should be kept for this purpose may be inserted through the gullet into the rumen, by which a means of escape for the gas may be made. The alkaline liquid mentioned may be poured into the stomach through the tube of the probang, or an opening may be made through the flank into the rumen with the trochar and canula, (fig. 74), or by a small bladed knife. This opening should be cautiously made at the spot where the greatest swelling is found. In the latter case a quill should be inserted into the hole to allow the gas to escape. If the passage be stopped by solid matter, a wire may be put through the quill to restore the opening. The ammoniacal liquid previously mentioned, or a solu- tion of a teaspoonful carbonate of soda in quarter of a pint of water may be injected through the quill with a common syringe. Afterwards the following may be given with the horn : Epsom Salts 2 ounces. Ginger 1 dram. Water 1 pint. If the production of gas still continues, a dram of chloride of lime dissolved in water will tend to remove the gases generated by the now decomposing food. Where none of these appliances are at hand, the following sub- stitutes may be used, viz : Flour, lard, and salt, to form a bolus mixed with one dram of carbonate of ammonia, at the early stage, or one dram of chloride of lime at the later stage. Small boluses of this mixture to be placed on the root of the tongue or into the gullet, so that they may be swallowed. Sulphuric ether is some- times given in doses of two drams each in cold water, it is a valu- able stimulant and antispasmodic when the animal becomes rigid or convulsed. 198 THE SHEPHEBD'S MANUAL. The after treatment should be tonic, and the food should be light and not bulky. Bran or oat-meal, scalded and well salted, and given with 1 dram of ginger would be useful. The return to copious green food should be gradual, until the stomach has re- gained its tone. Poisoning. — At certain seasons sheep are tempted to devour injurious herbs or plants. St. John's- wort, when frequent in pastures, produces sore mouth and irritation of the intestines, which quickly disappear when the sheep are removed to a more wholesome pasture. The Sheep-Laurel, Lamb- kill, or narrow-leaved Kal- mia, (Kalmia angustifoUa)^ (see fig. 75), is eaten by sheep which have access to it at certain seasons, chiefly during the winter and spring, and is often fatal to them. The symp- toms of poisoning are dis- inclination to move, froth- ing at the mouth and nose, lessened pulse, stagger- ing gait, and blood-shot eyes. Immediate attention should be given, as death generally occurs within twelve hours. To dilute the mass of poisonous food, and to expel it from the system as soon This may be done by Fig. 75. — SHEEP-LAUBEL. as possible, is the proper treatment. DISEASES OF THE BOWELS. 199 giving two ounces of Epsom salts in a pint of warm water, and re- peating the dose of water without the salts in an hour. Injections of warm soap suds will help to remove the injurious matter from the bowels. To prevent the danger of poisoning by carefully re- moving all injurious plants from the pastures or fences around them would be the obvious duty of the careful shepherd. The large leaved Laurel, (Kalmia latifolid), is also eaten occasionally by sheep. In England, the yew tree, which is common in hedges, causes the loss of hundreds of sheep every year. Sheep should not be allowed to feed on pastures which have been dressed with gypsum, lime, soot, or any chemical fertilizer until after one or two copious showers have washed the herbage clean. Inflammation of the Bowels.— This disease, (the braxy of the English shepherds), is not frequently met with in this country, except as an adjunct to some complicated inflammatory blood dis- ease. It, however, sometimes occurs as the result of continued in- digestion, or the consequence of feeding upon dry, innutritions pasture, combined with bad water in hot weather. The first symptoms are weeping and redness of the eyes, weakness and staggering, loss of appetite and rumination, inaction of the bowels, swelling of the flanks, high fever, and diflScult breathing, a puck- ered up appearance of the mouth and nostrils, which gives a pecu- liar wo-begone and pained expression to the face ; a tight skin and rapid emaciation. After death, the stomach is found filled with putrid food, and distended with gas; the bowels are gangre- nous and in a state of decomposition ; the liver is partly decom- posed and filled with degenerated bile ; the spleen is gorged with blood, softened, enlarged, and not unfrequently ruptured, ulcer- ated, and exhibiting a seriously diseased condition. The latter ap- pearance seems to identify this complicated and fatal disease with the splenic apoplexy or Texan or Spanish fever of cattle. Death is often very sudden, many sheeep left in apparent health at night, being found dead in the morning ; at the most, two or three days is the usual course of this disease. To prevent it, when circumstances favor its appearance, an abund- ant supply of pure water and a change of pasture should be provid- ed. Low grounds should be avoided, and everything done that can ameliorate the circumstances of privation in which the flock may be temporarily placed. It is not epizootic, and the removal of the causes will prevent the spread of the disease. A supply of salt, mixed with one per cent each of sulphate of iron, ginger, and gen- tian, to be given every evening to the sheep on their return from pasture, will be a useful preventive. The treatment should con- 200 sist of bleeding from the jugular vein, at the first appearance of the disease. Bleeding from the vein on the abdomen has also been practiced with success. Mild aperients — an ounce of Linseed or Castor Oil or Epsom salts— are useful, and should be followed by twice daily doses of one dram of Sulphite, (not sulphate), of Soda. The food should be liquid and demulcent, such as oat-meal gruel, infusions of linseed or solutions of gum arabic. Except the ani- mal is a very valuable one, it will be hardly worth while to at- tempt a cure in a case of serious character, as the recovery is slow, and the f ollowing debility is of itself often fatal, after a costly and protracted course of treatment. Concretions of Foreign Bodies in the Stomach. — Sheep are some- times observed to purposely swallow earth in small quantities. In pasturing green fodder crops or roots, much earth, and sometimes small stones, are swallowed. In eating hay, or other dry fodder, foreign matters, such as nails, pieces of wire, or glass, will some- times find their way into the stomachs. All these matters cause much irritation, and sometimes death. The trouble is shown by a suspension of the appetite, the sheep lag behind the rest, stand for long periods without moving, grind their teeth, poking out the nose, and depressing the ears. When the flank is pressed a grunt of pain is heard, and there is violent purging. When these symp- toms are observed, and the sheep are known to have been in danger of swallowing any of these substances, this cause may be suspected. The only treatment that can be of use is to give daily doses of one ounce of Epsom Salts, and feed scalded bran or corn-meal in the shape of thick mush in order to remove the foreign matter with the food if possible. If this will not be taken, oat-meal or corn-meal gruel should be given copiously with the horn. Balls of wool and earthy matter are sometimes found after death in the stomachs. These are gathered by the sheep nibbling them- selves when irritated by lice, ticks, or scab. Generally they exist without suspicion of their presence until death occurs, and in many cases without known ill effect on the animal. It would be safe to avoid possible danger in this direction by keeping the flock, especially the lambs, free from parasitical and irritating insects. Congestion of the Liver. — When sheep are highly fed upon stim- ulating food, and have but little or no exercise, the liver is apt to become gorged with blood. This fullness of blood is termed con- gestion. It is occasioned by disordered digestion, and when it exists to a serious extent, occasions further complications of this DISEASES OF THE LIVER. £01 important organ. It produces constipation, dullness, and a yellow- ish tinge of the eyes. As soon as this latter sign appears, there should be no delay, lest inflammation supervene. The treatment consists in giving an active purge, to be repeated every morning, until the bowels are in their usual healthy condi- tion, the yellowness of the eyes has disappeared, and the appetite has returned. The purge may be the following, given in molasses placed upon the tongue : Epsom Salts 1 ounce. Calomel 3 grains. The patient should be supplied with slightly warm drink soon after swallowing the medicine. Inflammation of flie Liver. — By neglect, the disease, last men- tioned, may result in inflammation of the liver. When this hap- pens the system becomes fevered ; the nose and mouth hot and dry ; the breath fetid ; the ears cold ; the eyes pale and glassy ; the pulse is irregular ; breathing is slow, and the expirations short and sudden ; the dung is dry, hard, black, and glazed with a greasy yellowish-green mucus ; the urine is highly colored, scanty, hot, and smells disagreeably. Pressure on the right side, near the short ribs, produces pain, and the animal moans. The treatment consists of purgatives and injections. For a pur- gative, the following may be given twice a day in infusion of lin- seed or gum arable or in molasses, well mixed together and placed on the tongue : Sulphate of Potash 2 drams. Calomel 5 grains. Powdered Opium 1 grain. Injections of warm water and castile soap may be given until the bowels act freely. When improvement occurs, and the appetite returns, great care in feeding should be observed, and only the most easily digested food should be given. Pulped sugar beet, scalded clover-hay chaff, linseed-meal, boiled malt, or sifted corn-meal, may be given with linseed tea for drink, or water acidulated with a few drops of aromatic sulphuric acid. DISEASES OF THE BLOOD. The blood being the very foundation of the life of the animal, must exist hi a state of purity, or the vital functions are at once disordered. Anything, therefore, that vitiates the blood or unfits it for the proper performance of those functions which have been 20'Z THE SHEPHERD'S MANUAL. already explained, produces what is known as blood diseases, or diseases originating in and communicated to various organs by the blood. These may be classified as follows : 1. Diseases arising from an impaired, increased, or arrested function, or process, viz : rheumatism, plethora, anasinia, scrofula, dropsy. 2. Diseases called enzoblic because arising from animal poisons, originating either within the subject, or communicated by the same poisons originating in other animals, viz : influenza, dysentery, red-water, heaving or after pains, navel-ill in lambs, black-leg or quarter-ill or anthrax fever. 3. Diseases arising from animal poisons of unknown origin, and which are highly contagious, and freely communicated from one subject to another, hence called epizootic diseases, viz : Epizootic aphtha, small pox. Fortunately these diseases so fatal in their operation, and so un- controllable in their course, are easily prevented by proper precau- tion and ordinary hygienic or sanitary measures. Also in the salt, sulphite of soda, we have a valuable remedy against those ferments which are the active agents in the majority of blood diseases. Rheumatism. — This disease is attended with considerable fever, constitutional disturbance, and the presence of acid matters in the blood. It affects the serous membrane, as the coverings of the joints, the substance of the tendons and ligaments, the enveloping membranes of the heart, lungs, spinal marrow, bones, muscles, and the brain. As it has a disposition to change its locality almost in- stantaneously, and to pass from one joint to another, or one part to another, (a process known as metastatis), and affects all these important parts of the body, the seriousness of the disease is evi- dent. It consists in a peculiar inflammation of the parts affected which causes acute pain when they are called into action. When it passes from the acute to the chronic state, it causes serious changes in the structure of the joints affected. Its symptoms are general uneasiness and stiffness, a diminished or capricious appe- tite, and sometimes, suspended rumination. The dung is hard and scanty, and the urine is high colored and deficient in quantity. One of the joints is found hot and swollen; in an hour or two this is relieved, and another is found affected. It generally attacks in spring those animals which have been half starved or exposed to cold or damp during the winter. Rams, which have been over- worked the previous season, are often affected. Young ewes are rarely troubled with it. If not remedied by proper treatment, the DISEASES OF THE BLOOD. 203 animal suffers from continued fever, general prostration, severe pain and emaciation, and eventually dies miserably. The treat- ment consists of a moderate purgative at first, suck as : Epsom Salts 2 ounces. Spirit of Nitrous Ether 4 drams. Ginger 1 dram. to be followed by Sulphate of Potash 2 drams. Sulphuric Acid 530 drops. Water V* pint. to be given dissolved in water night and morning. Protection from cold and damp, and soft, laxative food are required. Lin- seed-meal, either solid or made into gruel, ic a useful addition to the food. As this disease is apt to become chronic, the patient should be fitted for the butcher as soon as possible. A rheumatic ram will beget rheumatic lambs. Plethora consists in a too rapid production of blood, by which the system is engorged, and important organs become congested. It is caused by over-feeding with rich albuminous food, and is counteracted by a simple purgative, or bleeding from a vein on the face or the jugular. Its effects appear in a flushed condition of the visible membranes, labored breathing, staggering and sleepi- ness. It never occurs except in animals in high condition, such as those prepared for exhibition, and which hi case of over fatigue, or excessively hot and damp weather, suffer greatly, and sometimes fatally, from engorgement of the vessels of the lungs or train, or both. Anamia or Pining. — This term, "the bloodless condition," in- dicates the nature of the disease. There is a condition to which sheep may be brought by the effects of dysentery, or by parasites in the lungs or intestines, which much resembles this disease. But there is an abnormal state of the blood caused by imperfect nutri- tion, which is in itself a disease, and not a symptom. When from continued wet weather the pasture becomes rank and watery, the flock appears at first in an excellent and thrifty state, but in a few days the animals are found lying listless, with drooping heads and ears, watery eyes, and the expression of the face miserable and painful. A few days afterwards the skin is tightly drawn, the wool becomes of a peculiar bluish cast, the skin beneath of a pearly white color, the eyes are also of a pearly bloodless appear- ance, and death is busy in the flock. On dry, rich clover pastures the same effects are sometimes experienced. The disease never appears on steep, rocky hill sides, where the pasturage is short and 204 THE SHEPHERD'S MANUAL. sweet, nor on those pastures which are scant, but yet nutritious, and intermixed with coarse herbage ; nor on lands that are abun- dantly supplied with lime. It is impossible to know beforehand whether the pasture will produce this effect or not, as it seems most probable that the geological character of the soil has most to do with it But when once a farm, a pasture, or a field, is found to induce this ailment, sheep keeping may be abandoned upon it, unless the flock can be immediately changed to some other part of it where it will thrive. A change from a pasture field to a corn field, where the picking amongst the hills furnished but scanty feed, has been found to produce an immediate change for the bet- ter. No treatment, other than a change of locality, can be indi- cated, and if the farm does not supply this, the flock must be dis- posed of or removed. The disease unfortunately is not well un- derstood, for it is sometimes found very destructive to lambs and yearlings, which are chiefly affected by it It is frequently confounded with a parasitical disease hereinafter referred to, but a post-mortem cximination of a subject will easily identify it as being different from it as shown by the absence of parasites in the stomach, lungs, or air-passages. An adequate supply of supple- mentary food would of course act as a remedy, but the cost of this would defeat its object and render the flock unprofitable. Scrofula — Tuberculosis. — This disease is almost surely fatal in course of time, although at first the sheep subject to it may be brought, by proper treatment, into condition for the butcher. It is a question, however, if the flesh of scrofulous animals can be safely consumed as food, but yet many such go yearly to the butchers to be thus disposed of. It would certainly seem that the use of such animals as food should be carefully avoided, and the sale of then- flesh prevented as injurious to the public health, for no taint is more readily conveyed to the system than scrofula. It is supposed to consist of a diseased condition of the blood, by which the lymph, or white, serous, uncolored portion of it is unfit- ted to nourish properly the tissues of the body and to be built up into organized matter. Lest the accumulation of this imperfect blood should embarras the system, it is deposited in various parts where it is productive of least inconvenience, and the nutrition of the body goes on, as well as it may, with the remainder of the blood thus separated from the useless and injurious portion. But it is frequently the case that there is not sufficient left to supply the waste of the tissues, and a gradual falling off in condition oc- curs. The symptoms of " consumption," a very significant term, as the chief organs are slowly consumed, then appear. The pulsa- Z3TZOOTIC DISEASES. £05 tions of the heart are loud, so as to be heard on applying the ear to the ribs; the poise is feeble, the appetite irregular, and a slight cough exists, caused by the efforts to throw off the accumulating and offending matter from the rungs. In time, the giands of the body become loaded with the deposited matter; those of the throat and neck, the parotid and snbmaxfllary, being most commonly and extensively affected, and greatly swollen. The symptoms gradually increase in intensity, and there is much fever and ema- ciation, with discharge from the nose and eyes. The skin is tight and pate, and the body appears almost free from blood, as in anaemia. At this period there is no help for the animal, for death is only a question of time. The treatment in the earlier stages is to administer some of the preparations of iodine, such as the following : Iodide of Potassium 5 grains. OB Iodide of Iron 10 grains. to be finely powdered and mixed with molasses, and placed on the root of the tongue, so that it is swallowed. The above dose to be given daily. The latter preparation is to be preferred. The swellings may be robbed daily with iodine ointment Koscroro- loos animal should be osed for breeding, as the disease Is heredi- tary. High-bred sheep are the most sobject to this disease, and ** in-and-in breeding" tends greatly to produce iL In some localities an enlargement of the glands of the neck, similar to the disease known as yoitre in mankind, is frequent amongst sheep. This is supposed, doubtless with reason, to be caused by the water drank, as in such cases the removal of the flock to distant pastures has led to the disappearance of the dis- ease. The occurrence of the symptoms above described, however, will be sufficient to indicate the true character of scrofula as dis- tinguished from any accidental swelling of the glands. Droptg consists in the effusion of a watery or serous fluid in the abdomen. It is accompanied with inflammation of the lining membrane of the abdomen, the peritoneum, from which the fluid is secreted. It is caused by feeding upon rank, succulent, watery herbage, by which the blood is insufficiently nourished. A change to dry food, or scanty but more nutritious pasture, allevi- ates the disease at once. A cure is generally effected by the use of diuretics, aperients, and tonics. The treatment will be the ad- ministering of the following, or such others as may produce the desired effect: 206 THE SHEPHERD'S MANUAL. Nitrate of Potash 1 dram. Sulphate of Soda 1 ounce. Ginger 1 dram. If the animal is in low condition, the sulphate of soda may be re- placed by the following, viz. : Linseed-oil 2 ounces. ENZOOTIC DISEASES. Influenza. — This disease being due to causes which occur over an extended locality, is liable to affect a large number of animals at the same time. It is erroneously supposed to be infectious. It consists of inflammation of the nasal and bronchial passages, con- siderable fever, and great prostration, with general disturbance of the system. There is redness and weeping of the eyes, running at the nose, cough, great weakness, loss of appetite, indigestion, with impaction and sometimes hoven, or distension of the rumen. It is prevalent after continued cold and damp weather, and is most severe where the ground is low and undrained, or in river bottoms or valleys, where morning and evening mists abound. When Ihese conditions occur, the flock should be kept on high, dry ground, or in dry, sheltered yards, and carefully protected. Their food should be somewhat improved, linseed-oil-cake or corn-meal, buckwheat, oats, or rye, being added. A dose of the mixed salt and sulphur, (1 quart of salt with 4 oz. of sulphur), should be given, and any ailing sheep should be well nursed and treated to warm gruel. These precautions will generally prevent a serious attack. The treatment, when the disease becomes severe, is to give a light dose of some saline purgative, such as Epsom Salts »/a ounce. Ginger 1 dram. in a quarter of a pint of water, or mixed with molasses or honey. For a large flock the medicine may be mixed in bulk in proper proportions, and a quarter of a pint given to each sheep by means of a horn. Those more seriously affected should receive the fol- lowing, viz : Tincture of Aconite 10 drops. Solution of Acetate of Ammonia 1 ounce. To be given every four to six hours, decreasing the aconite at each dose until five drops only are given, when it may be suspended, and only repeated in an emergency L If the eyes are much inflamed, they should be washed with a ENZOOTIC DISEASES. 207 solution of one grain of sulphate of zinc, and 20 drops of lauda- num, in one ounce of water. After recovery, the feed should be laxative and nutritious ; bran mashes, and boiled oats, or corn- meal mush, with a little powdered ginger or gentian, and a pinch of powdered blue vitriol, (sulphate of copper), in each mess, would be useful. If not readily taken hi the food, this tonic may be given for a few days in honey or molasses. Shelter is absolutely necessary during treatment and recovery. Dysentery may be distinguished from diarrhea by its more se- vere symptoms, there being much fever ; the dung is mixed with blood and mucus, has a fetid smell, is discharged frequently, and is generally in hard lumps and scanty ; it is also voided with pain, and the sheep arches its back and moans in its passages. The wool feels harsh, and after a short time may be pulled off in hand- f uls. Sudden changes of pasture, from poor to rich, or from rich to poor ; dry, indigestible food ; scanty or impure water ; severely hot and damp weather such as produces rust in grain, and negle'ct- ed diarrhea, are the chief causes. Where large flocks are kept on extensive ranges, the best course is to remove to some other pas- ture, where the water is good, the ground high and dry, and other favorable conditions abound. The treatment proper for this dis- ease is to give a laxative in the first instance, as follows : Linseed-oil.. 2 ounces. Powdered Opium 2 grains. to be given in linseed tea or oat-meal gruel. The linseed or oat- meal should be continued several times during the next twenty- four hours, both as nutriment and for its soothing qualities. The next day, and for several days, the opium should be repeated with one dram of ginger. An occasional dose of linseed-oil may be given if thought necessary. It can do no harm, in any event, if given every other day. The effect of a hot sun, in an unshaded pasture, is very aggravating to this disease. Sheep suffering from it should be kept, if possible, in a cool shed, and separated from the rest of the flock. A pasture that has been occupied by such sheep will certainly infect others that may feed upon it during warm weather, the dung conveying the poison to the herbage. Red- Water. — When sheep are suffered to pasture upon succulent green crops, such as rape, mustard, or turnips, late in the fall or in the early winter, and the fodder is covered with hoar frost or sleet, or when they are forced to scrape their food from beneath the snow, swallowing a large portion of snow with their food, or when the stock water is drawn from filthy ponds or sloughs, they 208 THE SHEPHERD'S MANUAL. are subject to a peculiar disorder which often affects the majority of the flock quite suddenly, and is known as red-water. In this country this disease is rare, being known chiefly in the south-west and west, along with the last mentioned disease and some other disorders originating from exposure and unwholesome food or water, under the general name of murrain. The symptoms of this disease agree with those of a so-called " unknown and new disease" affecting sheep in the west, which has been described recently by correspondents of the Agricultural Department at Washington. The sheep affected appear dull and stupid, and stagger, carrying the head upon one side, the eyes are staring, and sometimes blind, and the bowels are obstinately costive. They die in a few hours. When opened the belly of the sheep is found filled with a red fluid wrongly supposed to be blood. There is also general congestion of the principal organs. As a preventive, the use of salt is recommended, and a table- spoonful of pine tar given to each sheep every ten days has been found useful. A pound of Epsom salts dissolved in water with two oz. of ground ginger, may be given to every ten sheep. The simple removal of the causes and a brisk .purgative or diuretic would doubtless lead to a recovery if given in time. When inflammation occurs from neglect, the bowels become affected, and death is rapid. The peculiar nature of the sheep makes treatment at this stage almost hopeless, but if it is attempted, that prescribed for inflammation of the bowels would be proper. After-Pains in Ewes, or parturient apoplexy, arises in conse- quence of a feverish condition at the time of lambing. It oc- curs about the second or third day, and its presence is shown by panting, straining, heaving of the flanks, a staring look, scanty and high colored and strong smelling urine, costiveness, and swell- ing and redness of the external hinder parts, which finally be- come purple and black. After death the whole system is con- gested, and the veins filled with black blood ; the uterus or womb, is charged with pus, the absorption of which poisoning the blood, is the cause of death. This disease is easily prevented by reduc- ing the condition of the ewes when it can safely be done. The safe time is some weeks before lambing, when a gentle purgative should be given and the food gradually reduced. A bran mash with 15 grains of saltpeter may be given daily for a few days. A very gradual course of depletion only should be adopted. If, after lambing, trouble is anticipated, the appearance of the ewe should be closely watched. If the pains occur, the following sedative should be given at once : ENZOOTIC DISEASES. 209 Camphor Va dram. Laudanum 60 drops. These are mixed with molasses and placed on the tongue ; the dose may be increased one-fourth for large ewes when the pains are excessive. One ounce of solution of acetate of ammonia may be given four hours afterwards, and repeated twice at equal inter- vals. If a fetid discharge takes place from the vagina, a solution of one dram of chloride of lime to a pint of warm water may be injected. The food of the ewe should consist principally of infu- sions of linseed or oat-meal gruel. Bleeding is injurious, as are also violent purgatives. Black Leg, Quarter IU, or Anthrax fever, is known as the "black spaniel" of the English shepherds, the cliarbon of the French, and as one of the "murrains" of our western states, where it is most frequent in this country. It affects young and thrifty sheep, and is rarely found amongst old or poor stock. It appears in the spring or early summer, and also in the fall months ; and mostly in wet seasons, when the pasture, under the fervid heat of the sun and unusual moisture, grows luxuriantly. Then the sheep, with vigorous appetite, gorge themselves to repletion, the digestive organs are overtaxed, the blood is disorganized, and be- fore any trouble is suspected, the sheep drop and suddenly die. When the carcasses arc examined, and the wool which leaves the skin at the least touch, is removed, the body is found to be swollen and blackened in large patches, chiefly on the forequarter, the flank, or the hindquarter. Air is gathered beneath the skin, and on opening the body, it is found decomposed and filled with black blood. If the flock is then observed, some will be found lame and limping, and on examination the sides or quarters will be found swollen, and when the hand is passed over these spots, the •wool readily comes off, and a crackling sound is heard from the motion of the air or gas collected beneath the skin. The mouth and tongue are found to be inflamed and blistered, and the eyes red. The urine is dark, the bowels constipated, and the dung when discharged is bloody. By and by the animals are unable to stand, and fall upon the side, stretch out the limbs, and protrude the tongue ; the belly is swollen, and in a few hours the sheep is dead. The disease is much worse in rich bottom lands, or moist, black soils, and rarely appears on hilly ground, or gravelly, dryjjoils. To prevent this disorder, it is only necessary to pre- vent the causes, to ensure regular feeding, and avoid sudden changes from poor to rich food or the reverse. The treatment 210 THE SHEPHERD'S MANUAL. should be an immediate purgative. The following may be given in oat-meal gruel or any other thick mucilaginous liquid : Sulphate of Soda 2 ounces. Mowers of Sulphur \ ounce Powdered Myrrh .'.1 scruple. A teaspoonful of spirits of nitrous ether in a pint of water may be given in six hours afterwards. If taken at the commencement of the symptoms, this treatment will probably be effective, but if later, the uncertain remedial action of nature alone can be de- pended on. EPIZOOTIC DISEASES. Aphtha, or "foot and mouth disease," which has grievously affected the herds and flocks of Europe, is not unknown in Ameri- ca. Fortunately our drier climate, or some other preservative in- fluence, has very greatly circumscribed the course of this disease. It has appeared in various parts of the country, but only sporadi- cally, or in scattered cases, and never yet has it swept over an entire district. Nevertheless, no one can be sure that it never will so appear, and as an isolated case requires the same treatment as any other, it is well that the disease should be described here. It is a true blood disease, belonging to a class of eruptive fevers aris- ing from a poisoning of the blood, and is highly contagious under favoring circumstances. It affects alike cattle, sheep, pigs, hares, and rabbits. It appears as an eruption of watery blisters upon the lips and tongue, and between and around the hoofs. The first symptoms are a fit of shivering, succeeded by fever, cough, and an increased pulse. This is succeeded by a failing of the appetite, tenderness over the loins, flow of saliva from the mouth, and grinding of the jaws. Blisters, small and large, appear on the mouth and tongue, which break and become raw, causing great pain. The feet are swollen and also covered with blisters, which break and become sore, causing the animal to walk with difficulty and shake its feet or kick or lie down persistently. In from ten to fifteen days the disease runs its course, in favorable circum- stances, and the animal recovers gradually, and is never affected afterwards. Otherwise the symptoms increase in severity, the sheep lose condition rapidly, from inability to eat or move about ; the hoofs are sloughed off, and sometimes even the bones of the feet are cast off, leaving only a stump. In-lamb ewes when affected, abort. It is considered, where this disease is virulent, that the cheapest and most effective plan is to stamp it out by the SHEEP POX. slaughter and burial of every infected animal, and the removal of those that are well. In the simple form, a single brisk purgative, such as two ounces of Epsom salts, with a small quantity of gin- ger, generally results in a cure ; to repeat the dose is dangerous. The mouth should be washed in the following solution twice a day : Alum in powder 1 ounce. Tincture of Myrrh 1 fluid ounce. Water 1 quart. The feet, if affected, should be washed with soap and water, or with a weak solution of sulphate of copper, then dressed with car- bolic ointment ; and afterwards bound up in a cloth so as to keep sand or dirt from irritating the sensitive surfaces. Sulphur should be burned in the sheds as a disinfectant and purifier, and the drink- ing water should be acidulated with one dram of aromatic sul- phuric acid to a gallon of water. All sick animals should be isolated. Sheep Pax, or variola, is a formidable and fatal disease, which is very frequent in the central and eastern parts of Europe, and has recently been introduced into England by means of importations of infected sheep. Although unknown in its severe type in this country, yet we have no security against its introduction at any day. It is recorded in a German publication that on one occasion every sheep in a whole district was swept off by this disorder, the sheep dying without any apparent reason, as though they had been poisoned. The only known preventive is artificial inocula- tion by means of lymph taken from one of the mildest cases. These communicated cases are exceedingly mild. The practice of housing sheep is very productive of this disease, and it is when sheep are kept in small flocks and well supplied with fresh air and general good care that the disease makes no headway. Whenever our flocks shall be overcrowded, and poorly cared for, this disease may be apprehended. Sheep-pox is not identical with the human small-pox, but is yet of the same type, produced by the same causes, has very similar characteristics, and is equally contagious. It cannot, like that of the cow, be communicated to mankind, nor to other animals than sheep, even by inoculation, and belongs ex- clusively to them. It is a true blood poison, caused originally by the absorption of impure matter into the blood, probably through the lungs, and the course of the disease is an effort of nature to throw off the poison by the eruptions which appear on the skin. There is a period of incubation of the disease, which lasts nine to eleven days after infection, and during which no symptoms whatever appear. After this the sheep sicken, refuse food, and 212 THE SHEPHERD'S MANUAL. suffer from quickened breathing, a hot, dry skin, an unquenchable thirst, redness of the eyes, and a discharge from the nostrils. At this period the eruption occurs on the body just as in the hu- man small-pox. The bare skin under the arm-pits shows the first indications of the eruption. Pustules or pimples surrounded with a red ring, (the areola), appear, and gradually after three days, come to a head, and take on a white appearance. It is at this stage of the disease that the matter is collected and preserved for the purposes of inoculation. The symptoms decrease at this stage and the sheep improve. The pustules dry up and form scales or scabs which fall off and lea^e in their places "pits" or marks. But it may be that these pimples run together or become " conflu- ent " and ulcerate. If this happens, the sheep almost invariably die. Otherwise the recovery is rapid. Treatment by medicine is entirely unavailing. Good nursing of the patients, and the use of sustaining stimulants with laxative and demulcent food includes all that can be done. Linseed-meal, rice-meal, and oat-meal, made into drinks, and given warm, with a small quantity of sugar, or molasses and ginger, will be sufficient in the shape of food. Pure soft water made slightly warm, and acidulated with a few drops of aromatic sulphuric acid, should be given for drink. Hopeless cases should be ended at once. If at the last stage the symptoms become worse, and the pimples, instead of becoming brown and drying up, ulcerate, and run together in chains, the animal should be killed and buried in a deep pit with plenty of lime thrown on the carcass. Every portion of the dead animal will convey infection, and in no case should the wool be taken from it, unless it be at once tub-washed in boiling hot soap-suds. On the appearance of the disease in a neighborhood, the unaf- fected sheep should be inoculated. A quantity of the matter from the white pimples is kept in bottles and diluted with water to the consistency of cream. A needle mounted in a wooden handle — a shoemaker's curved awl will answer the purpose excellently — is dipped into the fluid and is thrust beneath the skin of the fleshy part of the tail. This rarely fails to communicate the disease which is so slight as seldom to interfere with the feeding of the flock. In a paper published in the Journal of the Eoyal Agricul- tural Society of England, Vol. XXV, Part 2, 1864, written by a gentleman who had had charge of flocks of Merinos varying from a few thousand up to twenty-five thousand, in Russia, and who always practiced inoculation, the author states that although the sheep under his charge were constantly exposed to contagion DISEASES OF THE BLADDER. 213 from neighboring flocks, in which thousands died from neglect of this precaution, yet he never lost a single adult animal from the dis- ease. In those countries where the disease prevails, every shep- herd has an inoculating needle amongst the implements of his profession. As we are as yet exempt from this disease, and as it is readily communicated by contact with the skin or fleece of a diseased sheep, and with the present rapid communication between this country and Europe, an animal might easily reach here within its period of incubation, constant watchfulness should be exerted to prevent its importation. That we shall always be exempt, is too much to reasonably hope for. DISEASES OF THE URINARY ORGANS. The urine of a healthy sheep is alkaline. Under some circum- stances the urine becomes acid. This abnormal condition pro- duces a disordered condition of the highly sensitive urinary or- gans. If the flow of the urine is obstructed, it is absorbed into the circulation, and a variety of diseases are produced, all of which have one constant distinguishing symptom, viz : tlie strong smell of urine given out by the other secretions of the system, but especially by the secretions of the skin. The blood is poisoned by the absorption of the matters which the urine should have car- ried off, and a high condition of fever is consequently produced. Male animals are more frequently affected than females, by reason of the peculiar structure and length of the urinary canal, already described. Fattening animals are especially subject to urinary disorders, and such need close inspection and great care. Inflammation of the Bladder is the most frequent of the urinary diseases. Feeding upon second growth clover, which often con- tain lobelia, St. John's- wort, rag weed, and other irritating plants; or upon excessive quantities of corn-meal, or drinking hard wa- ter, are the chief causes. The acid and consequently irritating character of the urine inflames the inner coats of the bladder. The inflammation spreads to the muscular substance around the neck of the bladder, and this is contracted, closing the opening. Retention of Urine is therefore the direct consequence, and this involves the serious complications already mentioned. The symp- toms are uneasiness, constant lifting the hind feet and stamping with them, spreading them out and straining in the endeavor to void urine. As the attempt is abandoned, the animal moans in pain. There is general disturbance of the system, fever, and costive- 214 THE SHEPHERD'S MANUAL. ness. The remedy is to bleed copiously from the neck and to give the following to a large animal. Linseed-oil 2 ounces. Laudanum. 2 drams. For smaller animals the dose should be reduced proportionately. If there is no improvement the second day, the bleeding should be repeated from the other side of the neck, and one ounce of linseed oil be given daily until relief is procured. Diuretics and saline purgatives should be avoided. After improvement the food should be light, and infusions of linseed-meal or of gum arabic, would be useful. Sediment in the Urinary Canal. — Highly fed sheep, or those fed on dry pastures, which are deficient in water, or those care- lessly denied a full supply of water in winter, when they are fed grain in less or greater quantities — rams and wethers especially — are those which are subject to this disorder. Females, from the large capacity of the canal, are never, or very rarely, affected. But in male animals the peculiar appendage, called the vermiform, or worm-like appendage, through which the canal finds its exit, be- ing very small, an easy obstruction is offered to the passage and discharge of any sandy or muddy deposit of the urine. Small stony concretions are often discovered attached to the wool or hairs around the vent on the belly of the sheep. When these are noticed, extra care should be exercised to give abundant water by which the deposit may be dissolved and carried away. When the deposits have been arrested in this narrow passage, the urine is seen to pass drop by drop and the animal exhibits great pain and uneasiness. All the symptoms of retention of urine then appear. The treatment is to place the animal on his rump and draw the penis out of the sheath. It will be found inflamed and tender. It should be fomented with warm water, and the urethra or canal below it gently pressed with the fingers to force out the urine and with it the sediment. If this is successful even in part, some sweet-oil should be applied to the parts, and a rather large dose of linseed-oil be administered along with an antispasmodic to act on the neek of the bladder, viz : Linseed-oil 3 ounces. Extract of Belladonna 10 grains. On the following day the urethra should be again examined, and the manipulation be again repeated. One dram of Carbonate of Potash should then be given, dissolved in water, three times a day. If fever is present, the belladonna may be repeated, but only in case of urgency. No saline purgatives are to be DISEASES OF THE URINARY ORGANS. 215 given in affections of the bladder. If the sediment cannot be passed, it will be necessary to remove it by an operation. A lengthwise in- cision is made, with a small sharp knife blade, at the junction of the vermiform appendage with the urethra, on the lower surface, and the stones or gravel are removed by pressure. It may be dis- covered in this manner, that the obstructions exist all along the urethra, in which case there is no hope of recovery, and the ani- mal may be slaughtered. In case of wethers the vermiform appendage of the penis may be cut off at once. In rams it may be saved if possible, although it is not absolutely necessary for suc- cessful stock getting. It may be well, however, to be on the safe side, and save the part out of respect to the generally accepted be- lief that it is needful. It is known, however, that many rams which had lost the part by this operation, did not lose their useful- ness in consequence. Calculi, or stone in the bladder. For this disease there is no remedy, and if after the fact has been ascertained by the previously described operation, or in any other way, the animal may be killed. Clap or Gonorrhea. — This disease affects the sheath and ^enia) of the rani The first symptoms are very similar to those of sedi- ment in the urethra. There is gre.at pain in urinating, and the urine comes by a few drops at a time. In course of time a white acrid discharge escapes, and this, in case of neglect causes ulceration, which may destroy the organ. Rams thus affected should not be used, as the disease is contagious, and the symptoms are aggrava- ted. The causes are excessive work and want of cleanliness. The treatment consists of turning the animal on its back, withdrawing the penis gently, holding it with a soft linen cloth wetted with the lotion mentioned below, until all the diseased parts are seen. The organ is then bathed and washed thoroughly with the follow- ing lotion, viz : Spirits of Camphor 4 ounces. Sugar of Lead 1 ounce. Sulphate of Zinc 2 ounces. Water 1 quart. Mix and bottle for use. If any of the ewes have become diseased by contact with a diseased ram, a soft linen cloth may be wrapped around the finger, dipped in the solution, and inserted in the parts until they are thoroughly washed. Or a portion may be injected with a syringe. A daily dressing should be given until a cure commences, afterwards twice a week will be sufiicient. One ounce of linseed oil should be given every other day until the urine passes freely. The food should be laxative, and nothing stimulat- 216 ing should be given until a cure is effected. Copious demulcent drinks should be given, such as infusions of linseed, oat-meal, or gum arabic. DISEASES OF THE BRAIN. Water on tTie Brain, (Hydrocephalus).—This is a constitutional fault which is present in the ewe, or the ram, used in breeding. It exists in the lamb at birth, and the head is generally so unnatur- ally enlarged that it is killed as not worth raising, or it dies before it has arrived at maturity. If there are many cases in a flock, the ram should be changed ; if the ewes are at fault, they should be disposed of by feeding for the butcher. There is no cure, and an animal so deformed is a disagreeable object at the best, and it should be destroyed at birth. Apoplexy — Staggers. — Some of the high-bred sheep, the Leices- ters more especially, as well as some native sheep that have been poorly kept and fed, are subject to occasional attacks of giddiness and blindness, in which they stagger about and run against walls, fences, or other obstructions, evidently unable to see. The attack comes on suddenly, the sheep stops and stands staggering, or still moves on its former course with eyes dilated and prom- inent, but unconscious of impediments. The appear- ance of the eyes and mem- branes shows that the vessels of the head are full of blood, and post-mortem examina- tions have shown the brain to be highly congested, and some- times the vessels ruptured. Fig. 76.— THE FACIAL VEIN. Pressure of blood on the brain is the cause of these symptoms. Plethora from continued high feeding, or from indigestion or other disturbance of the condition of the digestive organs, produces this determination of blood to the head. Removal of the causes, depletion of high conditioned animals, by saline purgatives, or the restoration of the tone of poor conditioned ones by good food and tonics, tend to a cure. Bleed- ing from the facial vein (a, fig. 76), is often useful in extreme cases. Inflammation of the Brain (P7irenitis).—The causes which pro- duce apoplexy, if long continued, result in inflammation of the brain, and this produces frenzy. The affected animals are very DISEASES OF THE BRAIN AND NERVES. 217 violent, dashing hither and thijher regardless of danger or damage to themselves. Lambs thus affected leap and throw themselves about as if in violent play, until they fall and die in convulsions. The only remedy is copious bleeding from the neck, and active purging with salts. In this case no accompanying stimulant is needed, and for a full-grown animal, the dose may be increased one-half above the usual quantity. There is always congestion of the brain accompanying this disease, and treatment must be in- stant, lest in the muscular excitement the vessels of the brain be ruptured and sudden death ensue. Paralysis— Trembles.— This disease is a different manifestation of the effects of pressure of blood upon the brain from the two diseases previously described. In this disease, in addition to the base of the brain, the spinal marrow and the nervous system con- nected therewith are affected, the congestion occupying a consid- erable portion of the vertebral canal. Its effects are varied. In some cases the animal loses the power over some of its limbs ; the hinder half of the bodies of some are lendered incapable of mo- tion ; in others, the sheep stands, trembles violently, with ( the head drawn back or to one side, the jaws are tightly closed, 'and froth is forced through the teeth and lips ; the breathing is hur- ried, and the fit which lasts for a short time, recurs at short inter- vals. At other times the animal, which may appear perfectly well, will suddenly spring from the ground, scream, and fall dead. Others will fall deprived of motion, and remain sprawling, with limbs stretched out, until they die of starvation. The power of swallowing is gone, and there is generally very great difficulty of breathing in consequence of the affection of the pneumo-gastric nerve and the resulting paralysis or spasmodic condition of the muscles of the throat and chest. Animals in poor condition sub- jected to cold and exposure, suffer mostly from this peculiar form of disease. The treatment proper to these varied cases, depends upon whether the patient is in the active or collapsed condition. On the first attack, bleeding from the facial vein is the proper remedy, and generally gives immediate relief. But after the animal has passed through this stage, a condition of collapse follows, and in- stead of depletion, the opposite course is necessary to be taken. Tonics and stimulants are then needed. Warm milk or gruel, sweetened and mixed with ginger, followed by a teaspoonful of aromatic spirits of ammonia, or one scruple of carbonate of ammo- nia, mixed with gum water of cold linseed tea, should be given. If the bowels are constipated, a dose of linseed-oil (but no salts), 10 218 THE SHEPHERD'S MANUAL. should be given. The body may be swathed in a rag dipped in hot water, to which an ounce of ammonia water has been added. On recovery, the food should be generally improved in character, and a daily dose of one scruple of sulphate of copper may be given with some meal, or mixed with molasses and placed on the tongue. This disease is the most frequent one of the kind from which our flocks suffer. is a very similar disease to the preceding. It occurs chiefly in young or poor sheep which are turned out to feed early in the morning when the herbage is covered with hoar-frost or snow. The rumen being chilled, causes the blood to determine to the brain, and the animal becomes convulsed. No treatment can avail anything, but prevention is everything. Lockjaw, which is a violent excitement of the nervous system, sometimes occurs in consequence of exposure to wet and cold, and sometimes in consequence of injury to the nerves through the vio- lent twisting of the spermatic cord and vessels in the operation of castration. The jaws are closed, but can be moved laterally, and there is grinding of the teeth ; the head is bent round, the neck twisted, and one or more of the limbs are rigid. In this condition the sheep may remain a day and then die, or if it remain longer it may recover. A warm bath, if the sheep is not too large, is use- ful ; and the animal should be kept warm and in a quiet place. A dose of two ounces of Epsom salts should be given, followed by two drams of laudanum after two hours. Warm gruel, with a quarter of an ounce of ginger, should be given two or three times a day. Quiet and warmth are indispensable to a cure. Palsy. — This disease consists in a total suspension of action in the nervous system, generally in consequence of exposure to se- vere cold and wet. Lambs that are thoroughly chilled by cold rain and winds, or newly shorn sheep similarly exposed, are the most frequent subjects. Ewes having been exhausted by pro- tracted labor, or by abortion ; or newly dropped winter lambs, that have been neglected, also suffer from it. Heavy feeding on man- gels or watery roots has been known to produce it, and it has been stated recently that roots grown upon land that has been heavily dressed with superphosphate of lime, have produced this complaint in several English flocks. It is very questionable if the phosphate has any direct agency in producing it. The sheep suf- fering from it lie totally helpless, the whole body being incapable of movement, the respiration is almost stopped, and the eye is dead looking and lifeless, the eyelids quivering occasionally. PARASITICAL DISEASES. 319 The treatment consists in the application of warmth, and a stimulant such as mustard or ammonia and sweet-oil rubbed on the brisket and the spine. The following dose may be given twice a day, viz : Spirits of Nitrous Ether 2 drams. Powdered Ginger 1 " " Gentian 1 " Warm drinks should be given at short intervals. If the animal is purged, the chalk mixture prescribed for diarrhea should be given. If the palsy is not relieved by this treatment, the following may be given : Tincture of Nux Vomica 4 drops. OB Strychnine »/4 grain. diffused in a quarter of a pint of linseed gruel, and the dose slightly increased, afterwards repeated. In the case of a valuable animal, this potent medicine should be given with great care, or only by a veterinary surgeon. PARASITICAL DISEASES OF THE INTESTINES. Parasites which infest animals are divided into two classes, in- ternal parasites called entozoa, and external ones which are called epizoa. Since the natural history of microscopic animals and those which undergo changes only to be discovered by the use of the microscope, has become better known, much in regard to some peculiar diseases of animals, is now understood. Formerly it was believed that spontaneous generation of minute animalcule could occur, and that parasites were " bred " by diseased matter. What was then supposed to be the consequence of certain diseased con- ditions is now known to be the cause of them, and the whole subject of parasitical disease is in course of satisfactory explanation. But as yet there is much to learn, and the investigation of the subject is surrounded with difficulties. The most important of all the in- ternal parasites which injuriously affect the sheep is undoubtedly that known as The Liver Fluke, the distoma hepaticum of Rudolphi, or the fasciola hepatica of Linnaeus, which inhabits the gall bladder and ducts, and penetrates the substance of the liver. Its presence in this organ produces disorder of its functions and a diseased con- dition of the animal known as The Rot, oi' tfw Liver Rot. — This disease has been the most dreaded by the shepherd for centuries past. It has carried off 220 THE SHEPHERD'S MANUAL. Fig. 77. — SHEEP AFFECTED WITH ROT. millions of sheep in a single year, in Australia and South America, and is very prevalent in Europe. In 1830 two million sheep died in England of this disease. It exists in America both in imported sheep and the native flocks, and thousands die every year of it without their owners having knowledge of the cause. The symp- toms of the disease are, however, very marked and significant. In the healthy sheep the conjunc- tiva, or the membrane which covers the eyeball in front, and lines the eyelid, is brilliantly red ; so much so, that those un- used to observe these things closely, would suppose the eye to be highly inflamed. When affected with the rot, the con- junctiva is pale and eyeball yellowish. When this sign ap- pears, and the sheep is found to be ailing, it is certainly infested with flukes. There are other symptoms which indicate less certainly this disease, because they are found present in other ailments also, but this symptom is pe- culiar to this parasite. As the disease progresses, dropsy is always present, and a wa- tery tumor or bag appears beneath the lower jaw. The skin is pale and bloodless, and the wool is dry, harsh, ragged, and readily parts from the skin. The skin is drawn tightly, and the spine is arched and prominent, as seen in figure 77. The ap- petite is irregular, and de- praved, and the thirst excessive. These symptoms increase until the sheep dies completely emaciated. The fluke is a member of a family of sucking worms (similar to the leeches), known as distomaB. It is a flat, oval shaped animal more thickly conical in front, and has a sucker or mouth. Where the thicker part joins the flatter hinder part, there is a second sucker upon the underside. In figure 78 are shown the full grown flukes as taken from the gall ducts of a sheep, and in figure 79 are represented immature flukes from the same animal. The fluke is THE LIVER FLUKE. 221 a highly organized animal. It possesses a branched intestinal canal arid digestive organs, seen at figure 80, and a fully devel- oped circulatory system seen at figure 81. These figures are life- size. The fluke possesses the power of self-impreg- nation should a second individual not be present for copulation. It propagates by means of eggs, which are produced in great numbers, and which pass with the bile into the intestinal caDal, from whence they are voided with the dung of the sheep. Fig. 79. rp^ 6ggS nee(j to ke -Cashed by rain Or flood into stagnant water to become developed. The embryo, covered with ciliae or arms — the locomotive organs — leaves the shell and swims in the water. It is then believed, from our present knowledge of its habits, to penetrate the bodies of snails or other amphibious molluscs, and thus pass a stage of its existence. These soft-bodied molluscs being swallowed by the sheep which graze in low, moist pastures, along with the herbage ; the parasites contained in them are introduced into the stomach, from which they pass by the gall ducts, into the liver, and thus complete the round of their existence. They collect hi masses, sometimes closely pack- ed in the gall ducts, obstruct the flow of the gall, and set up irritation, and thus produce jaundice, by which the mem- branes are colored yellow. At this first outset of the disease the sheep seems to thrive and make fat rapidly, but the fat is highly colored, especially that of the kidneys and brisket. Some English feeders have purposely exposed their sheep to the flukes to hasten the fattening. But this stage passed, the structure of the liver becomes changed from the irritation and pressure ; the gall ducts become enlarged into extensive cavities, which are filled with flukes and their eggs. The pain thus caused makes the ani- mal restless and thin. The partial destruction of the liver, and stoppage of its functions, causes diarrhea, dropsy, and the disor- ganization of the blood, which constitute the fatal rot. The course of this disease is rapid. At the latter end the whole system is deranged. The breath is offensive, a deep distressing cough with fever racks the animal, the skin is covered with yellowish and Fig. 80. Fig. 81. 222 THE SHEPHERD'S MANUAL. black patches ; the abdomen enlarges from the accumulated fluid ; the animal is very weak, and lies with its head thrust out, solitary and separate from its fellows until it dies. On opening the sheep, the whole carcass is literally rotten. Yellow serum follows the knife everywhere, the abdomen being filled with it. The liver is found full of hard spots and ulcers, and the ducts filled with flukes. The treatment consists wholly in prevention or in attention at the first stages. When the rot has become developed, no medi- cine avails anything. It is wholly and surely prevented by keep- ing the sheep on dry pastures and away from stagnant water. The fluke there can find no development. Low pastures should be drained, ponds fenced off, and well water used for drinking pur- poses. Hay from low grounds may even communicate this dis- ease. When these preventive measures cannot be wholly carried out, the sheep should be abundantly supplied with salt, and on the first appearance of suspicious symptoms, the following mixture should be administered, viz: Saltpeter I1/? ounce. Powdered Ginger 1 Carbonate of Iron (colcothar of vitriol) ya " Salt 1 pound. Boiling water 3 quarts. The above to be mixed, and when nearly cool, 9 ounces of spirits of turpentine are to be added. The whole is bottled in quart bot- tles for use, and when administered should be well shaken to mix the ingredients thoroughly. Infected sheep should be kept from food all night, and on the following morning, before feeding, each should receive two ounces (a wine-glass full) of the mixture by means of a horn. No food should be given for three hours. The medicine is repeated every fourth day for two weeks. Sheep may live and thrive, and yet carry flukes. How many they can tolerate without serious injury, is a question that will probably never be satisfactorily answered. It is proper that the shepherd should be always on his guard against them, for the reason that this animal is now known to be native in this country as well as in almost the whole world. Deer, antelopes, and hares have been found infested by them. A careful and trustworthy naturalist, Mr. Joseph Batty, a member of Prof. Hayden's explor- ing expeditions, has discovered over a hundred flukes in the liver of one hare in Minnesota. A fluke, of which figure 82 is a draw- ing from nature, reduced one-half, was taken by Mr. Batty from the liver of a deer in the winter of 1874-5. The liver in question THE LUNG THREAD-WORM. 223 was filled with them, and a number of them are now preserved in the museum of the Smithsonian Institute at Washington. The author found them (along with numerous specimens of atrongylus filaria, in the lungs), in the flock of South- downs belonging to Royal Phelps, Esq., of Babylon, L. I., and also in his own Cotswold, Leicester, and native sheep, which had been allowed to pasture occasionally along the banks of a stream, and to drink for a whole summer at a running spring in which many watercresses and other aquatic plants grew. In these cases the medicine above prescribed brought about an entire cure. As the course of the disease is rapidly ex- haustive, sheep that are affected should be well fed with nutritious and easily digested food ; Fig. 82.— FLUKE a pint per dav^ for each gheep^ of Hnseed-oil- 5EB' cake-meal mixed with bran, will be of the greatest service on their recovery, or as soon as the appetite returns. The Lung Strangle. — The "lung thread-worm," (strongylus filaria], lives in the wind-pipe, the bronchial tubes, and the tissues of the sheep's lungs. It is a white, thread-like worm, from one inch to three inches in length. Its natural history is supposed to be as follows. The worms present in the lungs breed and produce eggs, which contain fully developed young, wound up in a spiral form in a thin shell. These embryos soon leave the shell and move about in the tubes, causing great irritation and a secretion of mucus, upon which they feed and grow. It is not certainly known as yet if the sheep in the violent coughing caused by the irritation expels any of the eggs or young worms, and that they then pass a portion of their existence in the open air, finding their way into the lungs of fresh bearers by the trachea in the passage of the food through the mouth or gullet, or from the stomach in the act of rumination ; or if the worm completes its whole existence in the lungs of its bearer. It is most probable that the former sup- position is the true one, as it explains the fact that the worms are often found in young lambs in such quantities as to cause suffoca- tion. Besides, it is known that flocks which follow other sheep upon pastures, or which feed upon fields that have been manured with sheeps' dung, have been attacked with this disease. An in- teresting case in point is stated by a Pennsylvania correspondent of the Country Gentleman of March 25th, 1875. Some ram lambs were pastured in a field upon which their dams had been kept the 224 THE SHEPHERD'S MANUAL. previous year, and which had been top-dressed with manure from the sheep sheds. Nineteen out of forty of the lambs died. The f ollowing year twenty-three lambs died, and the post-mortem of the physician showed the fact that the larynx and trachea were cov- ered on their inner surface " with a frothy mucus, generally white, but here and there of a yellowish hue," also in this mucus were "several worm-like bodies about one-half a line in diameter, and from one to two inches in length." Under the microscope these proved to be articulates, some of which contained what seemed to be ova. A microscopic examination of the mucus showed these ova in various stages of development. The worm -like bodies were undoubtedly the lung thread-worms under consideration. For several years afterwards the lambs which pastured on the top- dressed meadows took the disease and died. The symptoms which indicate the presence of this worm are a loss of condition, a con- stant and severe cough, a dropsical condition, as shown by the watery tumor beneath the throat, and a pining and wasting away. The skin is pale, and the eyes pearly, and bloodless. After death there is no sign of disease, except the presence of the worms in the lungs and windpipe, and complete emaciation. The means of prevention are obvious. Pastures or meadows should not be top- dressed with sheeps' manure unless they are to be plowed and sown to grain crops, and if a pasture is found to be infected, it should be plowed up and re-sown. All sheep having the charac- teristic cough should be fattened and killed. The treatment proper in this case is the same as that recom- mended for the liver fluke, and the mixture mentioned on page 222, should be administered as there stated. Turpentine and salt are found to be almost sure remedies for internal parasites of all kinds, and extra feeding to resist the draft upon the system will be useful. Hydatids or Bladder -Worms. — The association of the dog with the sheep upon farms, is productive of much mischief in addition to the vast annual slaughter of the latter occasioned thereby. The great majority of dogs are infested with tape-worms. The eggs of the tape-worms discharged in the dung of the dog upon fields and pastures are swallowed by the sheep with the herbage, and the larval state of the worms is developed within their bodies, either in the lungs, the abdomen, or the brain, causing disease which is often fatal. The larvae of the tape-worm exist in the shape of watery bladders, or sacs, which contain the undeveloped worms. These peculiar creatures are known as bladder- worms or hydatids. HYDATIDS OR TAPE-WORMS. 225 Ffe. 83. One of these occupies the abdominal cavity of the sheep, and is called the Diving Bladder-worm, Cysticercus fcnuicollis or C. tcsnia margina- ta. These bladders are often free in the abdomen, are sometimes enclosed in the fat, and sometimes are attached to the liver and intestines. They are pear- shaped, and in size from that of a walnut to that of a hen's or even a goose's egg. These bladders or cysts, when fed to a dog, have produced the mature tcenia marginata upwards of three feet in length in the course of three months. The eggs of this tape-worm have been fed to lambs, and have produced the hydatid, or bladder-worm, of which hundreds were found hi the abdomen of some of the lambs, which died soon after receiving the eggs. Figure 83 is a representation of the Cysticercus tenuicollis, with the head turned out- wards, and with the head contained within the neck of the blad- der. Another of these hydatids is the Many-headed Blad- der-worm, or Cysticer- cus tcenia echinococcus. — This finds a home in the lungs and liver of the sheep and other ruminants, and also infests mankind. Fig- ure 84 is an illustra- tion of the liver and lungs of an infected sheep. As many as several hundred cysts have been taken from one sheep. This is a most dangerous para- site, for if taken into the human stomach, it may produce " bladders" in the brain, as it actually has done in well authenticated cases, which are certainly fatal. The cysts reproduce themselves by a INFECTED WITH HYDATIDS. 226 THE SHEPHERD'S MANUAL. species of budding, and thus rapidly increase and spread through the bodies of their bearers. The most common of these hydatids is The Brain Bladder-worm, or Ccenurus cerebralis. — This produces the common disease known as turnside, or giddiness, in which the sheep turns its head to the left or right, and walks round and round in a circle in the direction in which the head is turned, until it falls giddy and exhausted. The presence of this parasite has been discovered in the liver of our gray squirrel, and in rab- bits, as well as in numerous sheep in this country. In the sheep it is generally found hi the brain, although it is not peculiar to that organ. It is only there, however, that it produces the usual disastrous effects upon the sheep. Figure 85 represents the Fig. 85. — HYDATID IN THE BRAIN. Fig. 86. — BRAIN WITH FOUR HYDATIDS brain infested with but one hydatid (a) ; in figure 86 it has four of them (a, b, cy d). In size they are from that of a pea up to that of a hen's egg. The hydatid is a bladder filled with a viscid fluid, and covered on its outside surface with marks or oval slits. These slits are the spots to which flask-shaped appendages are affixed within, and are the openings which lead to the interior of these appendages. On examination with a common pocket lens, a por- tion of .the bladder appears as in figure 87. The appendages are the necks and heads of the immature tape-worms, each head hav- ing four suckers and a series of hooks which are characteristic of the mature creatures, and by which they afterwards attach them- HYDATIDS IN THE BRAIN. 227 selves to the coats of the intestines, while they suck the juices therefrom. These heads increase by a process of budding, and often amount to dozens, and sometimes hundreds hi number. The pressure exerted by these bladders upon the brain, produces the peculiar symptoms exhibited, and the act of turning to one side or the other, helps to determine the seat of the hydatid in the body of the brain, which is found to be on that side to which the sheep turns. The natural histo- ry of this parasite is as follows : When the head of a sheep, containing the bladder-worms Fi g^^^g MAGNIFIEI). of this species, is devoured by a dog, the larvae are transformed within him into tape-worms. This worm (tcenia ccenuri^s) at maturity, or its eggs, being voided by the dog upon the grass of a pasture, are swallowed by the sheep, are hatched in its stomach, and penetrate all parts of the body, perishing everywhere except in the brain, which is its usual habitation. There they develop, remaining dormant, until chance favors their round again. Old sheep are rarely affected by this parasite, the lambs suffer chiefly from them. One infested dog will void thousands of eggs which not only escape with the dung, but being attached to the anus, are carried about and dropped in a multitude of places. To prevent the spread of this parasite, it is necessary only to prevent the heads of 'affected sheep from being devoured by dogs or hogs, or to keep dogs from the pastures. The heads of sheep dying from the disease should therefore be burned, and not thrown out. The treatment of sheep subject to the parasite consists in an operation by which the skull is pierced and the bladder punctured, when the water in it escapes and is absorbed, leaving the worm to perish. The pressure and irritation upon the skull causes some absorption of its substance, and a soft spot is caused over the blad- der. This may be easily felt by pressure of the finger. A curved awl may then be inserted through the skull and the bladder pierced ; or by means of a tubular saw (or trephine), a round piece of bone is cut out of the skull, a flap of the skin first being laid back, and the bone being lifted, the bladder is laid bare and removed. The skin is relaid and held in place by a stitch or plaster, and the 228 THE SHEPHERD'S MANUAL. wound heals. No other remedy than these is safe or certain, and these frequently fail. This class of parasites possesses some importance to the shepherd, not only from the loss occasioned amongst his flock, but from the danger of the results to the consumers of mutton. The farmer's or shepherd's own dog may be the means of injury to his flock, and he should take means to free the dog from the tape-worms by means of proper medicines, of which the powdered areca nut is the most effective, as well as to prevent vagrant dogs from stocking his pastures. The areca nut is administered as follows. Previously, one scru- ple of jalap, for a dog of 20 to 30 pounds in weight, should be ad- ministered, and a brisk action of the bowels set up. This may also be procured by giving the dog a quantity of butter or any of the common purgatives. Immediately afterwards half an ounce of the powder of areca nut is to be given in pills or in some ac- ceptable food. Some locks of tangled wool dipped in grease or melted fat are given at the same time to be swallowed. The worm is killed or paralyzed by the areca nut, is entangled in the wool, and all together are expelled by the purge. The mass should be immediately burned or buried at a perfectly safe depth in the ground. Applied to every dog at intervals of three months, this treatment will free them from tape- worms, and prevent danger of the sheep becoming infested with them. Tape-worms, (tcenia pUcata), in the intestines. The sheep them- selves are sometimes infested with mature tape- worms. This is easily explained by the possibility of the sheep swallowing along with their pasture some of the eggs which may have been voided by any of the numerous bearers of these worms, both domestica- ted and wild. It has been stated that the intestinal tape-worm is very rare, if not unknown, in sheep in this country. This would seem to be erroneous. A correspondent of the National Live Stock Journal of September, 1875, from Missouri, reported his lambs all dying of a strange disease in which the first symptom was a falling off in condition, followed by a mild diarrhea. This occurred in June, and continued up to August, when 30 out of 60 were dead, and nearly all the remainder were ailing. On exami- nation after death, the small intestines were found " packed full of tape-worms." This can hardly be a unique case, and we may very well conclude that tape-worm in the intestines is one of the parasitical diseases that we have to combat. Generally the symptoms developed by the presence of tape- worms are voracity of appetite, alternating with a refusal of food ; loss of condition, desire to swallow earth, stones, sand, or ashes ; PAKASITES OF THE SKIK. 229 the passage of soft dung, mixed with mucus, which becomes attached to the vent and tail, causing a very filthy condition ; and the evidence of internal pain. The sheep finally dies greatly ema- ciated. There is no means of prevention, as the eggs may be dropped by rabbits, squirrels, skunks, and other wild animals which frequent the fields. The treatment most effective is to administer turpentine as follows : Linseed-oil 2 ounces. Spirits of Turpentine Va to 1 ounce. This should be repeated twice a week for two weeks. If this is not effective, 3 ounces of the Powdered root of Male Fern may be given. The dose to be repeated in one week. In six hours after this is administered, a purgative of linseed-oil should be given. The food should be of the best kind until the lost con- dition is restored. Tape-worms in any of their forms of life, affect only young sheep and lambs. When sheep attain the age of two years they are safe from them, and it is very rare indeed that one older than this be- comes infested with them. Hair-worms in the Intestines.— jA. species of " hair-worm" called from its peculiar formation iricocephalus, is not uncommon in sheep. It infests the stomach and intestines, causing obstinate diarrhea, and rapid wasting of flesh. These worms burrow their heads into the membrane lining the organs, and suck out the juices. The irritation produces diarrhea, which submits to no treatment while they remain. A cough is often present along with the diarrhea. Other species of worms, of habits identical with these, and producing the same injurious effects, also infest the sheep, but more particularly lambs and yearlings. Salt in doses of half an ounce, given on alternate days with one dram doses of sulphate of iron, the salt being given on one day and the iron the next, is a very sure remedy for this class of parasites, and the dis- eases which result from their presence. To counteract the debili- tating effect of these parasites, the food should be of the most nu- tritive and digestible character, and linseed in some shape should not be omitted. PAKASITES AND PARASITIC DISEASES OF THE SKIN. Of the epizoa or external parasites of the sheep, the most formid- able is the Scab insect, or Acarus scdbiei. This is a minute mite which attaches itself to the skin and penetrates the surface, lodg- ing itself in the tissues and causing intense irritation or itching, 230 THE SHEPHERD'S MANUAL. and the secretion of a serous exudation which dries upon the sur- face and forms a scab. This disease was well known to ancient shepherds, and an exact description was given by the poet Virgil in his Georgics. It is mentioned by the historian Livy, as being very virulent in his time. But up to a very recent date the cause of the disease was not correctly known. Youatt's work on the sheep, published in 1840, by the English " Society for the Diffusion of Useful Knowledge," states it to be caused by bad keep, starva- tion, over-driving, dogging, exposure to cold and wet, and other causes of a suppression of the perspiration. He mentions the acari as carriers of the disease, but not as the cause. In an attempt to account for the origin of the insect, he makes the following re- marks, which in the light of our present knowledge are a curious relic of the ignorance which existed 40 years ago, and which has not yet quite passed away. " Physiologists are beginning to ac- knowledge the working of a mysterious but noble principle — the springing up of life under new forms, when the com- ponent principles of previous beings are decaying, or have seemingly perished. Thus, if we mace- rate any vegetable substance, the fluid will teem with my- riads of living be- ings, called into existence by the process we are con- ducting, or rather by that power of Nature, or that prin- ciple which was bestowed by the author of Nature, that life ceasing in one form shall spring up in others, and this while the creation lasts. Thus we have probably the hydatid in the brain of the sheep, and the fluke in its liver ; parasitical beings, which we recognise in no other form and in no other place. They were the product of the disease of the part. In like manner the acarus of scab may be called into existence by the derangements which our neglect, or unavoidable accident, or disease, may have made in the skin of the sheep. Scab may be, and is, of spontaneous ori- Fig. 88.— FEMALE SCAB INSECT. THE SCAB-MITE. 231 gin, as well as the product of contagion ; and the acarus, having sprung into life within the pores of the skin, obeys the laws of all living beings as to its after existence and multiplication." It shows with what caution speculations should be indulged in, and how much safer it is to say " we do not know," than to haz- ard explanations which may be wide of the truth and misleading. It has long been known that the origin of the existence of all ani- mal life is an egg produced and fecundated by parents, and the scab-mite being no exception to this law, comes forth from an egg and springs into life just as a chicken does. In both cases the egg is deposited and hatched, and produces the mature animal. The female scab insect, seen at figure 88, is larger than the male, which is shown at figure 89, magnified 2,500 tunes. One male suffices for many females, and is longer lived than the female. The latter dies after producing her eggs, which she deposits in the pores of the skin, or in the furrows of the scab which she has helped to produce. Her eggs are numerous, and being hatched in three days, her progeny increase rapidly. One female acarus can produce a million and a half of progeny in 90 days. This facility of increase explains the rapidity Fig. 89.— MALE SCAB with which the disease spreads through a flock, and proves the necessity for instant and energetic remedies or effective preventives. The symptoms first observed are restlessness and uneasiness, and the observant shepherd will have his suspicions aroused and search for the cause on the first appearance of these symptoms amongst his flock. As the disease progresses, the sheep are found rubbing or scratching themselves, or biting or nibbling amongst their wool. The attention should then be directed to the parts rubbed or bitten. If scab is present, the skin will be at first white in color and of a thicker texture than the rest, and moist or covered with a yellow exudation. Later these parts are covered with scab and the wool falls off or becomes loose. If a lock of this wool be laid upon a sheet of white paper, the mites will be seen with the unaided eye, as they crawl from it. If the disease is neglected, the scabby spots enlarge and increase in number, the wool appears ragged all over, and falls off in patches. Upon these bare spots dense brown or yellow scales are seen, and if the sheep can reach a fence or a post, the scabs are rubbed until they bleed and be- 232 THE SHEPHERD'S MANUAL. come sores. The condition of the sheep falls off rapidly, and it becomes a wo-begone object, such as is shown in figure 90. The treatment is by dipping in a liquid which penetrates and softens the scab so that it can be removed, and which poisons the insect. There are many preparations used for this purpose, some of which are objectionable on account of their poisonous proper- ties, such as mercurial or arsenical compounds, and which are no more effective than the following perfectly safe one. This consists of tobacco and sulphur in the proportions of four ounces of the first, and one of the second, to the gallon of water. The water is brought to a boiling heat, and the tobacco, either coarse cheap leaf or stems, which are equally good, is steeped, (but not boiled), in it until the strength is exhausted. The sulphur is then Fig. 90. — SHEEP AFFECTED WITH SCAB. stirred in the liquid. When it has become reduced in tempera- ture to 120 degrees, it is ready for use. The sheep are entirely immersed in the liquid so that the wool is completely saturated. Hard crusts of scab are broken up and removed with care, and the raw surfaces are well washed with the decoction. The dip- ped animals should be kept in a yard until the wool no longer drips, lest the pasture should be fouled, and the sheep sickened by the tobacco juice. After ten days the dipping is repeated to de- stroy any newly hatched mites. With care the most badly in- fected locality may be completely freed from this pest, and it will never appear if the sheep are dipped twice each year as a preven- tive. The gain in the growth of wool and in its improved quality will more than repay the cost of the operation. (See page 48.) The Sheep Tick (MelopTiagus ovinus), has been already referred to (page 48) ; if the process of dipping, just described, is regularly practiced, this parasite will be easily vanquished, and its annoying presence prevented. This insect propagates only by single eggs, or rather the perfect pupa is expelled singly from the female, THE SHEEP-TICK. 233 which is therefore termed pupiparous ; it does not, therefore, in- crease very fast, and is easily kept under. It is too well known to need minute description, its dark red, tough, leathery-skinned body be- ing a most conspicuous object, when the wool of almost any sheep in the co an try is examined. The pupa and mature sheep-tick, greatly magnified, are shown at figure 91. The Sheep-louse (Trichodectes ovis), is known as the red sheep-louse. Its head is of a red color, and the body pale yellow, marked with dark bands. It is found on the side SHEEP LOUSE. Fig. 91. — SHEEP-TICK AND PUPA. of the neck of the sheep, and the inner parts of the thighs and arms. It causes much irritation, by which the sheep is impelled to thrust its head between the bars of gates or fences, or to kick and stamp with its legs. Oc- casionally sheep are found strangled by becoming fixed in their attempts to rub their necks, or with their legs broken in attempts to rub them upon rails. Lice are rarely found on the yolky wooled sheep, but on the drier fleeced breeds they often cause much unsuspected mischief. Those sheep which are regu- 92- larly dipped, are also free from this pest. To rub parts mentioned with the following preparations is generally an easy remedy. Lard ............................................ 1 pound. Flowers of Sulphur ............................... 2 ounces. Creasote ......................................... 20 drops. one pint of sweet oil may be substituted for the lard. This louse is small, and the illustration, figure 92, is of one highly magnified. The Sheep Gad Fly ((Estrus oms). — T^his is a most troublesome pest, causing much discomfort to the sheep. It is a fly with two wings spreading over one inch, and a stout body over half an inch in length. In the summer months they disturb the sheep in the pastures by the efforts they make to deposit their eggs upon the animal's nostrils. When they succeed in their efforts, the sheep often becomes half frantic, and races violently over the pasture, sometimes seriously injuring itself by becoming overheated. Where the fly abounds, the sheep crowd together and stop feed- ing, holding their noses to the ground, and stamping with their 234 THE SHEPHERD'S MANUAL. . fore feet. The grub, when hatched from the egg, crawls up the nostril, and lodges in the sinuses of the head, where it remains feeding upon the mucus secreted by the membranes, until the fol- lowing spring. In entering the nostrils and in leaving them, they cause much irritation to the sheep. The remedy lies in prevent- ing the fly from laying its eggs, and this is done by smearing the nostrils of the sheep with tar, diluted with grease or butter. This is both distasteful to the fly and fatal to the egg. By preparing a pailful of the mixture, and smearing the noses of the sheep with a brush, as they pass one by one through a half opened gate, every morning during fly time (July and August), the sheep will be spared much annoyance. When grubs are crawling clown the nostril early in spring, they may be quickly dislodged by blowing tobacco smoke into the nose through a pipe. The Maggot, so called, is a formidable enemy of the sheep. It Is the larvae of the common flesh fly (Sarcophaga carnaria), the blue-bottle fly (musca Ccesar), and the meat fly (musca vomitoria), all of which deposit their eggs or living larvae upon decaying ani- mal matter. When sheep are wounded by accident, or are allowed to become filthy when troubled with diarrhea, these eggs or larvae are deposited in vast numbers ; the ovaries of a single Sarcopha- gus having been found to contain 20,000 eggs. The maggots soon become active, and spreading from their quarters, attack the skin, which they irritate and cause to secrete a serous fluid. In time the skin is pierced, and the flesh suppurates and wastes away, being devoured by the multitude of maggots which crawl upon it. In wet seasons the mischief is greatly increased. To prevent them it is necessary to carefully remove the wool from about the tail so that filth may not gather ; to watch for any accidental wound ; and in warm wet weather, for any dirty tags of wool upon which the flies may deposit eggs. In case any maggots are found, there is no better application than common crude petroleum, or whale-oil, both of which are repulsive and fatal to fly and maggot. A sheep that is " struck " with maggots will remain separate from the flock, and may be lost sight of unless the flock is counted at least once a day, and the straggler found. Weaning time, when the ewes may suffer from caked udder, is an especially critical period, and then extra watchfulness is called for. DISEASES OF THE FEET. Sheep are subject to many disorders of the feet. The structure of the sheep's foot is different from that of the horse. It possesses CONTAGIOUS FOOT-ROT. 235 no laminae which connect the outer crust or horn with the sensi- tive parts within, but the crust is connected with the bone by a vascular structure, by which it is also secreted. The growth of the hoof of the sheep is not from the coronet downwards, as in the horse, but from the whole inner secreting surface. In this lies both the weakness of the sheep's foot, and the rapidity with which repairs are made, when it is injured or diseased. The wall or crust surrounds the outside of the foot, and turns under at the edge of the sole and toe, and it is impossible to distingush where the crust ends, and the sole begins, both being so much alike in structure. The crust is harder and tougher than the sole, which is soft and elastic, like India rubber. As the toot wears down by contact with the ground, the crust is worn off to a sharp edge upon the outer margin ; when the wear and growth balance each other, the foot is in perfect condition ; but when either is greater than the other, the conditions of disease are at once established, and unless removed by proper treatment, lameness occurs. Another peculiarity of the sheep's foot is the interdigital canal, which commences in a small opening about one inch above the foot, passes downwards and backwards between the toes and ends in a pouch which is curved upwards upon itself. The canal is covered with hair, and is studded with glands which secrete an oily fluid. This fluid overflows at the opening, and moistens the skin between the toes, preventing chafing and sore- ness. The peculiar structure of the foot of the shesp, under unfa- vorable circumstances, gives occasion to several serious diseases. Of these the most frequent and important is Foot-rot. — This disease is contagious, and may spread through the flock, if preventive measures are not taken. It consists of an inflammation of the whole hoof, the formation of blisters upon the heels and between the toes, which break and form discharging surfaces, and in a few days, ulcers, which suppurate and excrete fetid matter. The fore feet are the most usually affected. When this happens the sheep may be observed to go around feeding painfully upon their knees. If no attention is given, the hoof is lost in course of time, and a wounded stump only is left. It is caused at first by wet pastures in which the feet become foul, the horn becomes detached under the sole, and harbors filth which softens the sole, and influences the vascular tissue beneath it. Neglect completes the conditions under which the disease oc- curs. The treatment should be immediate on the appearance of the first lameness, for when the ulcerative stage has arrived, the cure is long and difficult, the whole condition of the animal being 236 THE SHEPHERD'S MANUAL. involved. As soon as lameness is perceived, the sheep should be examined. All raw, loose, or diseased horn should be cut away with a sharp knife ; any excessive growth of horn at the toes should be removed, and if any pus or matter is found beneath the horn, that should be pared away until it is all exposed. The feet should then be washed clean with carbolic soap and water twice a week, and after each washing a piece of tow or lint dipped into ' the following mixture should be bound on the foot and between the digits, viz : Oxide of Copper 4 ounces. Arsenic Va " Acetic Acid 3 " Honey 8 " Or the foot may be thoroughly smeared with the following oint- ment, viz : Finely Powdered Blue Vitriol 1 pound. Verdigris Va " Linseed-oil 1 pint. Pine Tar 1 quart. This will dry on the foot and will not be washed off by the wet grass as a solution would be. The following remedy is in general use amongst French and German shepherds : Chloride of Mercury (Corrosive Sublimate) 15 grains. Acetate of Copper 30 Sulphate of Zinc. . . 30 Acetate of Copper 30 Sulphate of Zinc 30 Hydro-chloric Acid (muriatic) 2 drams. Water 2 ounces. The diseased parts to be touched daily with a feather dipped in the above solution. In case the disease has made considerable progress, and the sheep are found feverish and generally ailing, each sick one should receive, according to circumstances, a dose of one to two ounces of Epsom salts dissolved in half a pint of water. At the expiration of two days the following should be given, viz : Nitrate of Potash Va ounce. Flowers of Sulphur % " mixed with molasses and placed on the tongue until swallowed. This may be repeated once a week until the feet are well. When the disease becomes virulent, the foot is swollen, sinuses are formed, and ulceration progresses until the whole foot is deeply involved, and the sheep fails to eat, loses flesh, and is in a condition of fever from blood poisoning by the absorbed matter. COMMON FOOT-EOT. 237 The case is then often unmanageable except at greater cost than the value of the sheep. Fortunately such a termination rarely occurs, unless through great neglect or the most unskillful man- agement. In such a case the foot should be washed, the loose and separated horn removed with care, and the foot poulticed with a warm carrot or turnip poultice twice a day for three days, and the following should be administered at once : Epsom Salts 2 ounces. Laudanum 1 dram. After the feet have been cleaned by the poultice, the treatment before mentioned should be continued until recovery is made. The patient being unable to move without great pain, should be kept in a pen with a clean floor free from straw or chaff, or any- thing that would irritate the foot or convey infection elsewhere. A method recommended by the Hon. H. S. Kandall, who has successfully treated many of his own flock in this manner, is to procure a large tub or trough in which three sheep can stand at one tune, and to pour into this tub a hot saturated solution of blue vitriol (sulphate of copper), until it is four niches deep. The sheep having had their feet washed, and all loose horn pared off, are placed in the tub on their feet and held there by an assistant. The first sheep is kept in the foot-bath until the fourth is ready to go in, when it is taken out ; when the fifth goes in, the second is turned out. Thus each sheep remains in the bath about ten min- utes, giving time for the solution to penetrate every part of the diseased hoof. After the bath, the sheep are kept in a dry grass field. One application of this remedy served in every case, to make a complete cure. This troublesome disease is rarely known in this country upon dry pasture, and generally yields at once to a simple paring of the feet and shortening of the overgrown toes, a cleansing from all filth or irritating matter, and a dressing with an astringent ointment such as the first above mentioned. Common Foot-rot or Gravel, is not contagious, and being the re- sult of accidental circumstances, is cured by their removal, together with simple auxiliary treatment. It consists of an inflammation of the internal parts of the foot, the formation of matter, its escape at the top of the hoof, the separation of the horn or crust from the diseased parts, and as a matter of course, extreme lameness. It is caused by an excessive wear of the crust of the hoof upon stony, gravely pastures, or by excessive growth of the crust or toe, in low moist meadows. In either case, foreign matter enters between the crust and the sole, and pressing upon the sensitive 238 THE SHEPHERD'S MANUAL. parts beneath, causes inflammation, which not being at once rem- edied, increases with the above results. The means of prevention are obvious. The treatment consists in removing the offending matter with great care and tenderness by means of the knife or a small probe, as a knitting needle or wire, cleansing the foot, and washing it in astringent and antiseptic solutions, such as the following : Chloride of Zinc 1 ounce. Water 1 quart. sulphate of copper or sugar of lead may be substituted for the chloride of zinc. In very bad cases the treatment for malignant foot-rot should be adopted. Removal from wet pastures is neces- sary to a cure, and for some tune afterwards, or the trouble will quickly recur. Epizootic aphtha (foot-and-mouth disease), is highly contagious, and will rapidly spread through a flock. It affects the feet as well as the lips and tongue. The treatment has been already described in this chapter. Inflammation of tJie Interdigital Canal. — This is of frequent occurrence when sheep are driven upon sandy or dusty roads, are pastured on sandy lands, or are permitted to lie in muddy yards. Offending matter enters the canal and causes inflammation, which spreads to the interior of the foot, and results hi swelling and great tenderness. Removal of the irritating matter by means of a small probe or the trimmed end of a feather dipped hi oil, and bathing the foot in warm water and vinegar, are generally sufficient to re- move the trouble. When sheep become lame, and the foot is found hot, with no sign of outward cause, this may be at once suspected. Canker of ihe foot is a very obstinate disease. It consists of in- flammation of the sole of the foot, which gives way to a growth of spongy sprouts instead of the natural hoof, and a discharge of white curdy matter which has a most offensive odor. It is a simi- lar disease to thrush or canker of the frog in horses. The most frequent causes are folding the sheep in yards or sheds, where the dung is allowed to collect in a mass which ferments and heats, and from neglected cases of common foot-rot or inflammation of the interdigital canal. The treatment consists of the removal of all the separated hoof at the first and every future dressing, along with any that may appear sound, but has dead offensive matter beneath it. The foot should then be washed in a solution of one dram of chloride of DISEASES INCIDENT TO LAMBING. 239 zinc in a pint of water, and a pledget of tow or lint dipped in a mixture of one part of common (not fuming) nitric acid with three parts of water, should be applied to the whole of the cank- ered surface. This should be repeated frequently, until a cure is made. LAMBING AND DISEASES CONNECTED WITH IT. The number of lambs raised in proportion to those that are dropped is far less than it ought to be. Probably ten per cent of the lambs annually dropped, are lost through negligence or want of simple methods of protection. Many are lost through neglect of the condition of the ewes. The lambing season is one that calls for great patience on the part of the shepherd, rather than for great skill. A well disciplined flock, well provided with shelter and quiet retreats for the ewes, will raise a larger proportion of lambs than a neglected one. Dogs about a flock at lambing time are an unmitigated nuisance, and cause many losses. When the lambs begin to drop it is not difficult to discover those ewes that will come in, in twenty-four hours. The parts become red and swollen, and the udder swells and fills^ It is at this period that the ewes need close watching, both to discover anything that may go wrong, and to render assistance when it is needed. If the ewes have been carefully tended, there is rarelv any difficulty encoun- tered that may not be overcome by simple measures, yet amongst the most carefully tended flocks there will be some occasional cases which will call for the treatment herein described as ap- plicable to the disorders mentioned. There is rarely any necessity for manual assistance to the ewes at lambing time. Sometimes in cases of protracted labor it will be necessary for the shepherd to ascertain if the lamb is in proper position, with the fore feet and head first ; if it is, the ewe may be left alone with safetv. If the position is unnatural, help should be given by an experienced shepherd. If no aid can be obtained, it is dangerous for an inexperienced person to assist, lest he may be too hasty and rough in his help. If the lamb is presented in such a manner that it cannot be expelled, it should be gently forced back again by some person with a small hand, the hand being smeared with sweet-oil. It should then be gently brought into such a position that the feet shall be presented first, with the head lying upon them, and not doubled back. If the hind parts are presented, the feet should be gently brought up after the lamb has been pushed back. If the placenta or after-birth has not come away in due season, it may be gently pulled by the hand, when it will be generally expelled in a short time. If the ewe is weak, a little warm gruel, sweetened and flavored with ginger, may be fed with a spoon or given with a horn. It is the poor, lean, badly kept ewes which, suffer most in lambing ; those in good condi- tion, or even fat, rarely experience any difficulty. Parturient Fever rarely attacks our native sheep, but imported sheep are sometimes subject to it. It generally occurs within a few days of lambing. The first symptoms are refusal of food, twitching of the hind legs and ears, dullness and stupidity; the head is carried down, the eyes are half closed, and a dark colored discharge flows from the vagina. If the lamb is now dropped it is dead, but the ewe, if kept quiet and well nursed, will generally recover in two or three days. But if the lamb is not then expelled, the symptoms grow worse, the ewe suffers from fever, and moans with pain, and the discharge is very offensive. The lamb, if ex- pelled at this stage, is in a high state of putrefaction, and the ewe falls into a condition of collapse, from which she rarely recovers. If the lamb is not expelled, the ewe dies. The treatment should consist of the removal of the ewe from the flock to a quiet pen, on the first appearance of sickness. She should -be well cared for, and fed with warm gruel of linseed or oat-meal. As soon as the dark colored discharge occurs, the lamb is almost certainly dead, and beginning to decompose, and its re- moval is necessary. The vagina should be washed with warm water, and the finger, smeared with the extract of belladonna, should be introduced into the passage every three hours until it is sufficiently dilated to allow of the expulsion of the lamb. Two tablespoonfuls of the following medicine should be given twice a day, viz : Calomel ' 8 grains. Extract of Hyoscyamus 1 dram. Linseed Tea Va pint. At the same time a quarter of a pint of the following should be given alternately with the above : Epsom Salts 8 ounces. Nitrate of Potash Va " Carbonate of Soda 2 " Water 1 pint. The above mixtures should be shaken up before giving them. GARGET. After the bowels have been operated upon, these mixtures are omitted, and the following given : Nitrate of Potash Va ounce. Carbonate of Soda 1 . Camphor 1 dram. Gum Water ". 8 ounces. An eighth of a pint to be given twice a day. The ewe should be fed chiefly upon thin oat-meal gruel and milk, or infusion of lin- seed. After the lamb has been expelled, the uterus should be in- jected with warm milk and water, or if there is a very offensive discharge, one dram of chloride of lime dissolved hi a pint of warm water, should be injected instead of the milk and water. Abortion.— This disease is not frequent amongst sheep, and when it occurs can almost always be traced to the excessive use of roots in cold weather, when the ewe is heavy with lamb. It has also been known to occur in consequence of, or after, the heavy dressing of turnip or mangel land with superphosphate, the crop having been fed to the ewes, but this is probably in consequence of the greater succulence of the roots so grown, rather than the direct action of the phosphate. The distension of the stomach with cold, watery food, so greatly reduces the temperature of the abdominal viscera as to destroy the life of the foetus, which is pre- maturely expelled, with all the disagreeable consequences to the ewe described in the preceding paragraph. Chasing by dogs is a very frequent cause. The treatment is preventive and alleviative. Caution in feeding roots to in-lamb ewes in any but small quantities, or in avoiding fright, excessive exertion, and worrying, will prevent its occur- rence. When it has happened, the following may be given with some nourishing liquid food, viz : Epsom Salts i/a ounce. Laudanum 1 dram. Powdered Camphor ." i/a " The latter two only may be repeated the second day. Garget. — This disease consists of inflammation of the udder or milk glands. It rarely occurs, except in those ewes which have lost their young and are not supplied with foster lambs, or when the teats are not opened readily by the new-born lamb ; or at weaning time. If the ewe is in good condition, and has a large flow of milk, which is not drawn off, the udder becomes gorged, inflamed, and finally festers and suppurates. In this way some ewes may lose part or the whole of the udder, and their useful- ness as breeders be destroyed. It is also occasioned by allowing 11 •242 THE SHEPHERD'S MANUAL. a nursing ewe to lie in the wet and cold in the pasture or the yards. In the summer time, when lambs are taken from the ewes and sent to market, a ewe may become gargeted, and if neglected, may become a victim to myriads of maggots which will breed in the festering udder. Ewes are thus lost occasionally. It is obvious that prevention will be most effective. When garget has occurred, the Treatment is to give a purgative and diuretic to reduce the flow of milk and any fever that may exist. This may be the following : Epsom Salts 2 ounces. Nitrate of Potash. 2 drams. Ginger 1 " to be given in water, and repeated in twenty-four hours. The udder should be bathed in warm water, and a solution of carbon- ate of soda be injected into the teats by a small metal syringe, and afterwards milked out. The disease may result in the permanent injury of the udder, or the closing of one or both of the teats, in which case the ewe should be discarded as a breeder. Inversion of tlie Uterus may occur in cases of severe labor, when the ewe is weak. The womb is turned inside out, and pro- trudes from the body as a red bladder. From ignorance this is sometimes cut off, and the ewe destroyed. The parts should be gently washed in warm water and cleansed from all foreign mat- ter. The ewe should then be held so that the hinder parts are raised, and with a small hand well greased with sweet-oil, or pure fresh lard, the womb should be returned, gently working it into its natural position by the thumbs or fingers. The finger nails should be closely pared, lest they may wound the tender parts. A needle with a strong linen thread or fine catgut, should then be passed through the skin upon both sides of the vagina, and tied so as to form a loop across it which will prevent the uterus from again protruding ; 20 to 30 drops of tincture of opium should be given in some warm gruel, and the ewe left to rest upon a soft bed in perfect quiet with her hind parts raised above the level of her head, for several days. SPECIAL DISEASES, OPERATIONS, AND ACCIDENTS. Ophthalmia. — This is a disease of the eye frequently caused by cold, or by grazing in stubble fields, when the straws of the stub- ble will occasionally wound the eyes. It is perceived at once by the tenderness and redness of the organ, a flow of tears, and a discharge of pus from the corner of the eye. It is readily cured CASTRATION OF RAMS. 243 by washing the eye with a solution of four grains of sulphate of zinc in an ounce of warm water, and keeping the sheep in a dark stable for a day or two. If the eye is seriously inflamed, and the sheep distressed with pain, give a dose of an ounce of Epsom salts dissolved in water, and twenty drops of laudanum may be added to the zinc solution above mentioned with good effect. Castration. — This necessary operation should be performed as early as possible, as there is less danger of evil effects following it than when the lamb is older. The lining membrane of the scro- tum is a continuation of that of the abdomen, and when inflam- mation follows the operation, it is readily communicated to the abdomen, and peritonitis or inflammation of the membrane lining the cavity and enveloping the bowels results, and this is generally fatal. A lamb a week old may be deprived of the whole scrotum and testicles, by one stroke of a pair of shears, without any danger or the loss of more than a few drops of blood. But when the lamb has become spme months old, the organ has become fully developed as to nerves and vessels, and a more careful operation must be performed. An excellent method is for the operator to sit upon a long bench, with one of the lamb's hind legs beneath each of his thighs, the head and fore legs being held by an assist- ant. Taking the scrotum in the left hand, he presses the testicles towards the lower end, making the skin tight and smooth. He then makes a free incision with a sharp knife at the bottom of the scrotum beneath each testicle; the membranes which sur- round them are cut through, the cords and vessels which are at- tached to them, are scraped, not cut asunder, and the operation is completed. To castrate a mature ram, an incision is made at the bottom of each compartment of the scrotum, each testicle being removed separately, the cords and vessels being always scraped asunder. The main point to secure is, to have the wound at the bottom of the scrotum, so as to allow the pus, which will form within it, to escape. If this pus is retained hi the wound, it becomes absorbed, inflammation is communicated to the adjacent parts, and a fatal termination is likely to ensue. To prevent this, a small lock of wool is sometimes left in the wound, by which it is kept open and the danger averted. DocMng.— This operation should be performed on all the lambs when a week or two old. It is then but slightly painf ul. The best method is to take the lamb between the knees, holding its rump closely against a block of wood. Then drawing the skin of the tail towards the rump, with the ringers of the left hand, a 244 THE SHEPHERD'S MANUAL. sharp chisel is held by the right hand upon the tail, below the fingers, and two inches from the rump ; a boy gives the chisel a smart rap with a light mallet, and the tail is severed at one stroke with a smooth cut which leaves the bone in a good condition to heal quickly. A p"inch of powdered copperas may be placed on the stump of the tail to stanch any bleeding, and to keep off flies. Fractures of the limbs sometimes occur through neglect to let down bars when sheep are entering or leaving a fold or field, or through other accidents. These are easily repaired by bringing the broken ends of the bone together in the proper position, and binding the limbs in splints of wood. The splints should be wrapped with strips of cloth to prevent them from chafing the limbs, and the bandage should be made secure, but not so tight as to interfere with the circulation. The bandage should be worn three or four weeks, and if occasionally examined, there will be no need to shut up the patient from the rest of the flock. An excellent splint is made by soaking coarse brown paper in water and wrap- ping it around the broken limb and then binding it with bandages of muslin. When the paper dries a very firm support is given if sufficient is used. Wounds, either punctured, incised, or lacerated, may occur from a variety of causes. When a sheep is wounded, the first thing to be done is to wash the wound with a soft cloth or sponge and warm water. If blood flows freely from an important artery, and it cannot be stanched by the use of brown sugar or powdered cop- peras, the bleeding end of the artery should be sought, and twisted two or three times, which will usually stop the flow. A sheep will rarely bleed to death, except from a wound which severs the arteries or veins of the throat. It may faint from loss of blood, and the flow may then, or soon afterwards, stop. If the wound is a clean cut with smooth edges, it should be closed, the wool being clipped around it, and two or more stitches taken through the skin at the edges, by which they may be kept together. The stitch should be passed through the skin in two places directly opposite each other on either side of the wound ; the thread should then be tied tightly enough to keep the edges in contact, but no more, and tire ends cut off. Other similar stitches are to be made, and the wound is dressed upon the surface by smearing it with an ointment of tar and powdered blue vitriol. If the wound is punctured and deep, it should be dressed by injecting with a syringe a few drops of compound tincture of benzoin, and inserting in it a plug of lint or tow dipped hi the same. This will DISEASES OF LAMBS. 245 keep the wound open until it heals from the bottom. If allowed to close before the bottom is healed, an abscess will be formed, which will need to be opened. If the wound is in such a position that the pus formed cannot escape freely, it should be removed twice a day by means of a feather or a swab of linen at the end of a small stick, and the plug soaked in tincture of benzoin inserted. If any foreign matter, such as a splinter of wood, remains in the wound, it must be removed, if necessary by enlarging the wound, before it can heal. A wound that is dif- ficult to heal from its depth and narrowness, may sometimes be made more tractable by opening and enlarging it at the top. Lacerated wounds will need to be treated as both incised and punctured wounds. Where the torn parts can be brought to- gether, stitches should be made, and where the flesh is separated from the surrounding tissue, the fragments may be cut off. The deeper parts should then be treated as punctured wounds. Such wounds are long in healing, because skin is reproduced only from the edges of the sound surface. As many of the lacerated por- tions of skin as possible should be brought together, so as to form edges from which the^new growth may start. It will be a ques- tion if the value of the sheep in this case will repay the time and labor spent in treating it. If not, to take its skin at the outset may be the most advisable course. To cure a large wound in the fly season is a work of much trouble. Sprains are not uncommon accidents in a large flock. They are reduced very easily by rest, and the use of a liniment such as Olive-oil 1 pint. Ammonia Water... 2 ounces. DISEASES PECULIAR TO LAMBS. Lambs frequently fall victims to some diseases which seem to affect them more virulently than they do grown-up sheep, or else the young animal having less strength or vitality than the mature one, more easily succumbs to those diseases. In its earlier life it is also affected with some disorders peculiar to its condition. These diseases call for special treatment. The most troublesome ailment to which lambs are subject, are those of the digestive or- gans, and chief amongst this is Diarrhea or " White Scours". — In the unweaned lamb diarrhea takes the form generally known as " white scours." This appears 246 THE SHEPHERD'S MANUAL. as a liquid discharge of a white color, which is simply the passage through the bowels of undigested milk. It is caused by a change in the quality of the ewe's milk, which is not coagulated in the lamb's stomach, and remains as an irritative agent, exciting the bowels to undue action, by which the milk is discharged soon after it is swallowed, almost without change. The food of the ewe probably has much to do with this, as the trouble is most frequent when the ewe is fed upon rank, succulent, watery herbage, or an excess of roots. When this cause does not exist, it arises from a disordered condition of the lamb's stomach. When the former cause is suspected, the ewe should be treated. The food should be changed to other kinds of a more solid and nutritious charac- ter. A poorer pasture should be provided, or hay be given for a few days, along with some crushed oats and corn, or malt, linseed, cotton-seed-meal, bran, or peas. The lamb should receive the following daily, until recovered, viz : Linseed-oil 1 teaspoonful. Essence of Ginger 5 drops. When the cause exists within the lamb, two teaspoonf uls of the following astringent mixture may be given night and morning, after the before mentioned has operated, viz : Prepared Chalk 1 ounce. Powdered Catechu 4 drams. " Ginger 2 " " Opium "A " Peppermint Water , 1 pint. to be mixed. Shake before administering. Sometimes the discharge consists of a pale, greenish liquid, sim- ilar to whe}'- ; this is the result of indigestion, as the food of the lamb taken in excess is coagulated in the stomach, and accumu- lates sometimes to several pounds in quantity. When this occurs, in addition to the looseness and color of the dung, the lamb is dull, walks raoodily behind the ewe with its head drooped, and the abdomen is !iard and swollen. The following should then be given twice, viz : Carbonate of Magnesia, half ounce, mixed in water, to be followed by half an ounce of Epsom salts in a teacup- f ul of water, after which the astringent medicine should be given. This course of treatment should be followed in case of the " green scours," which may happen after weaning, when the lamb is turned upon clover pasture. Sometimes the presence of worms in the stomach and intestines will cause a looseness of the bowels. In such a case the discharge from the bowels will be mixed with DISEASES OF LAMBS. 247 slime or mucus. The treatment should then be as follows : give to a year-old lamb Linseed-oil 1 ounce. Powdered Opium 3 grains. Starch 1 ounce. mixed in boiling water to make a draught. A teacupful of rice water should be given twice a day. The above to be repeated the second day. After the irritation of the bowels is removed, give the following: Linseed-oil 2 ounces. Spirits of Turpentine 4 drams. to be repeated weekly for a month if considered necessary. Constipation. — When this occurs, the dung is scanty and at long intervals passes in lumps, which are glazed and hard. There is pain at the times of discharge, which is evinced by the arching of the back, and peculiar but expressive actions of the lamb. The treatment consists hi injections of warm water, with two or three half-ounce doses of linseed-oil, given at intervals of six hours. The food should consist of oat-meal, or linseed gruel, sweetened with molasses ; if it will not be taken hi that way, it should be given by means of a horn. Spasmodic Colic produces severe pains, occurring in paroxysms. The lamb falls and struggles, or remains with eyes fixed, as if convulsed. It is generally an accompaniment of constipation, and always of indigestion. The treatment is to give the following mixture, viz: Tincture of Rhubarb 1 dram. Carbonate of Soda 1 " Warm Water sweetened with Molasses 2 ounces. This should be administered slowly with a spoon. After the spasms are relieved, give half an ounce of linseed-oil. Paralysis. — This disease may occur through a severe chill or exposure to cold rains, or as a symptom of chronic indigestion from inaction of the stomach. The latter is to be suspected when the appetite is depraved, and sand, earth, and coarse matter is eagerly swallowed. In the former case, a warm bath, with fric- tion upon the spine, with spirits of turpentine, or ammonia water, followed by a few days nursing, may be found useful. In the latter case, the symptoms and post-mortem appearance show that the base of the brain, the spine, and the nervous system proceed- ing to the stomach are affected. The lamb suffers severely as if in great pain. It is unable to rise upon its hind legs, and is con- 248 THE SHEPHERD'S MANUAL. vulsed with spasms ; the teeth are ground together, and the breath- ing is quick and hard, and death generally results. The only defi- nite directions that are likely to result favorably, are to prevent the disease by watching the condition of the lamb after it is weaned, and to provide such food as shall keep it in a thriving condition. Poverty of blood being the direct cause, any treat- ment that will avoid that condition will be helpful. A small quantity of linseed-cake-rneal, bran, or ground oats, should be given daily after weaning, and until the first winter is past. Lambs of rapidly growing breeds cannot endure stinting in food, the de- mands of their constitution must be supplied to its full capacity, or the health suffers, and instead of becoming simply poor and stunted, they become diseased. Disease thus induced cannot be expected to submit to medicine, and the only natural remedy is apt to be applied too late to be of service. Pale Disease, Husk, Verminous Bronchitis, — This disease con- sists in the presence of worms in the air-passages of lambs. These produce great irritation and violent coughing. The interruption thus resulting to the aeration of the blood in the lungs, causes gen- eral disturbance of the system. The appetite fails, the condition rapidly falls off, and anamia, "pale disease," or "the bloodless condition," takes place, beneath which the lambs rapidly sink. How the worms, iu large numbers, find their way into the air-pas- sages of so young animals, is a query which as yet cannot be satis- factorily solved. They are there, however, and that fact must be sufficient for the shepherd. These worms are a species of strongy- lus or thread worm, closely akin to the fatal " gape-worm " (also a strongylus), which destroys so many young chickens. It is the same species which inhabits the lungs and bronchial tubes of the sheep. The lamb being less robust, is carried off with greater ease by these attacks, than the full-grown sheep. Prevention is the best remedy. Lambs should not be allowed to follow sheep upon the same pasture, nor to pasture upon meadows that have been top-dressed with manure from the sheep stable or yards. No medicine can reach the lungs, except through the blood, and but few affect them in this way. Sulphur, turpentine, and assaf oetida, are in part exhaled through the lungs, and these medicines alone can be depended upon to reach these parasites. The treatment recommended, therefore, is to administer the fol- lowing, viz : Linseed-oil Va ounce. Spirits of Turpentine Va dram. Assafcetida »0 grains. TABLE OF MEASURES. 249 to be given early in the morning, for three successive days, before feeding or turning to pasture, and no feed to be given for three hours afterward. Afterwards the following to be given daily : Molasses or Honey 1 pound. Flowers of Sulphur 4 ounces. one tablespoonful to be given every morning for ten days. The food should be of the most nutritious and digestible char- acter, and if the appetite fails, the food, until the appetite returns, should be given by means of a horn, in the shape of gruel or infu- sions of oatmeal, linseed, or corn-meal, sweetened with sugar. TABLE OF APPROXIMATE EQUIVALENT MEASURES. For the more ready use of the prescriptions mentioned in the preceding chapter, the following table of approximate equivalent measures is here given : FLUID MEASUBES. One teaspoonful = One fluid dram. One tablespooiiful = Half a fluid ounce. One wine-glassful = Two fluid ounces. One tea (not coffee), cupful = A quarter of a pint One tumblerful = Half a pint. It will be more convenient, as well as more accurate, to have an apothecary's graduated glass, which is not very expensive, and will allow all the needed measurements to be made in a single utensil. This is a conical glass upon a foot, and provided with a lip to pour from ; they may be had of the capacity of one or two ounces up to a pint ; one of four ounces will be the most conve- nient ; the measures are marked on the glass, the sign f 3 standing for fluid dram, and f § for fluid ounce ; Ss is used for half of either. A set of apothecary scales and weights may be bought for a dollar or less. The grain weights are of thin sheet brass, with number of grains indicated by dots. ^ stands for scruples, and 3 for dram ; the number of each being indicated by numerals follow- ing the sign ; Ss is used for half of either.
