(89.) Breeding from different families of the same race.—Mr Culley, though believing that no great harm can result from breeding in-and-in, yet appears to have in a manner preferred the preferable practice of breeding from different families of the same race; as he, for many years, hired his rams from Mr Bakewell, at a time when other breeders were paying a liberal price for his own valuable animals. This is of all methods deservedly the best, as the males, which are inter-changed, have always had shades of difference impressed upon them, by various soils and treatment, so that the defects of each family have a good chance to be counteracted by the perfections of the other. By this means the bad points are gradually exhausted, and their valuable properties as gradually heightened. Breeders have been much aided in the furtherance of this desirable plan, by the rearing of superior rams having become, of late years, a separate pursuit. The letting of them out to distant parts of the country has long been a branch of this speculation; diffusing some of the most valuable points of particular breeds, and leading to a spirit of competition. The practice has been reprobated, but, I presume, rather hastily; for with all its attendant evils, such as leading to deception, by what is termed the making up of rams, it possesses excellencies which will, I hope, lead to its continuance.
(90.) Crossing.-The only other method of improving a breed is by crossing two distinct races, one of which possesses the properties it is desirable to acquire, and wants the defects we wish to remove. This, however, is a measure not to be recommended, and only to be resorted to when neither of the others will do; for it is scarcely possible to obtain the desirable properties without at the same time imparting qualities sufficient to neutralize them; and with which, in fact, we would rather dispense. To cross, as Mr Cleghorn remarks, any mountain breed with Leicester rams, with a view to obtain a propensity to fatten at an early age, would be attended with an enlargement of size, which the mountain pasture could not support, and the progeny would be a mongrel race, not suited to the pastures of either of the parent breeds. The folly of such a proceeding is beautifully shown in the failure of the attempts made, some years ago, to better the fleece of the mountain sheep, in the South of Scotland. To effect this desirable end, rams were brought from the Cheviot range of hills, and the consequences were, as described by Mr William Hogg, of Stobbo, in the Quarterly Journal of Agriculture, just what a preliminary consideration of the existing circumstances would have proved to be unavoidable. "The independent habits of the mountain flocks were lost, and a mongrel progeny, of a clumsy figure, occupied the lowest and warmest of the pastures. As they were very improper subjects to breed from, they were often a drug in the market: but the store-master had no other resource, but to struggle on against the opposition which the animal itself made to the change, and, also, against the influence of bad seasons, in order to get the influence of the Cheviot breed fully established. * * * With its shaggy coat the animal lost its bold independent look, its stout shape, its unvitiated taste, and its sound constitution. A course of severe winters too occurred during the time of changing, while every property calculated to resist privation and fatigue was unconfirmed in the progeny; and, in consequence, the ravages by rot, and poverty, among the flocks that occupied soft pastures were immense." How did it happen, that the store-master had no other resource but to persevere in an unprofitable course? Was he obliged to strive against natural obstacles, which even a short experience might have taught him were, in that manner, insurmountable? Why not recur at once to the old mode of management, rather than injure himself by kicking against the pricks. "Sundry store-masters were not aware," says Mr Hogg, "that their old breed would so obstinately resist the impression of the Cheviot blood, nor did they ever dream that the mongrel issue would be so easily subdued by the hardships and cold of winter: thus finding their scheme opposed, at points where they anticipated little resistance, they gave up the experiment ere it was half completed, and introduced mountain rams to the mongrel issue." Enough, however, has been said to prove that this plan ought not to be pursued: let me now say a few words as to the reasons which should deter us from its adoption. To take a familiar illustration:—How would one of the worshipful company of Aldermen, or a dignitary of the Church, manage to keep up an appearance, if suddenly transported from the luxurious plenty which surrounds him, to the meagre fare, and churlish climate, of our Highlands? Would their offspring, which ten to one would be prone to rapid growth, and, therefore, requiring at the least a large supply of porridge and milk; would they, I ask, arrive at a healthy maturity, if supported only on the oaten cake, and whang of skimmed-milk cheese, of the hardy Northern? The answer is, they would not. They would, doubtless, bear the climate; but the habit of body imprinted on them, by the full living of the parents, would require a more nutritious food to bring it to the adult age, than what might be necessary for the sustenance of any child descended from the possessors of the soil. If such then is the case with the young of an animal shielded from inclemency on every hand, how can we expect the progeny of a rather heavy variety of a defenceless creature like the sheep to thrive, in defiance of every thing ungenial, on a pasture which requires for its collection, in any quantity, a degree of experience and activity, the result of time and well-trained instinct. The mongrel is not unfitted for the locality, as Mr Hogg would have it, by a weakness resulting from "the constant and continued exertions of the two bloods, the one endeavouring to overpower the other," there is no war waging in the progeny between the blood of sire and dam; the secret lies in the animal being unsuited for the pasture where it is produced. Place it in a country possessing a herbage something between that of the Highland and Cheviot hills, and it will do passing well; but do not ascribe the want of success to a natural hatred of the breeds. Again, do not fall into the error, that "the figure, wool, and other qualities, of the Cheviot ram, are most conspicuous (in this cross) in the smallest and feeblest of the progeny, while the properties of the mountain breed are more fully exhibited in the strongest and most robust lambs," a circumstance which, unfortunately, induced many of the store-farmers "to throw aside the best of the lambs, and select those to breed from, which had apparently most of the Cheviot figure;" or, in other words, do not suppose, as Mr Hogg strangely enough infers, that only the weak animals took on the Cheviot form, and only the strong ones assumed the Highland character. The correct explanation is, that such as had most Cheviot blood were sure to become puny, from being unadapted to a herbage on which those that resembled the mountain stock throve tolerably well. Strength and feebleness were, in this instance, mere secondary matters.
(91.) Things to be attended to in Crossing.—The fact is, that, if you wish to have a particular kind of sheep, you must first of all be in possession of a pasture suitable for the new comers. You must consider the influence of the individual parents on the progeny, the size of the animals, their habits and dispositions, and their peculiarities in regard to the time of their maturity, and fattening properties; and, having anticipated these apparently trifling affairs, you must see that the surface of your farm, its degree of exposure, and the quantity and quality of its productions, are calculated for the profitable maintenance of the animal in view. Far too little attention is bestowed, at the commencement of such an undertaking, on these all-swaying matters. Farmers enter upon this, the most arduous of all professions, with the settled conviction, that nothing is so simple as the engrafting of a race of animals on a particular part of a country. They have read, or heard, of others who have gained fame, and a fortune, by successful endeavours of the kind, and they think that nothing is easier than to follow their example; but they forget the thoughtful hours, and irksome duties, these men had to tolerate, before they could speak of any thing like success. No animal can be made to forego at once a long used food, an ancient locality, peculiarity of clime and season, and the instinctive habits that have been long nurtured by these, without both it and its progeny suffering from the change:—Nature cannot thus be made to bend to human intention; it will give way in the attempt.
In crossing there are several important things to be attended to. Well formed parents ought to be selected, and, if enlargement of the carcass be wanted, the issue should be better fed than its originators, which ought to be of a size rather under, than above what the pasture is capable of supporting. The size of the parents should not be much disproportioned at first, as nature abhors sudden extremes, and does every thing in the most gradual manner. It is better, when some increase has been attained, to bring the breed to the required size by one or two crossings.[ [15] In choosing a breed, we should adopt that which affords the greatest quantity of market produce, in return for the food consumed;[ [16] and a particular breed ought always to be preferred to the sheep of a district. We must not imagine, that when, by dint of crossing, we have obtained the variety wanted, that it will remain in the condition to which we have brought it, without the slightest liability to alter. Many farmers believe they have done all that is required, if they subject their stock to three or four crossings with a breed of acknowledged excellence. They think that the improved animals they have obtained will support their acquired characters, uninfluenced by extraneous agency. Now nothing can be more faulty than this mode of management, as is proved by a comparison of stock so treated, with flocks which have uninterruptedly received that undeviating attention, which can alone ensure a continuance of the properties desired. Such men forget, that the climate is operating with as great certainty on the animals as on the rocks around; and that as the herbage is determined by the nature of the adjacent rocks, so are the peculiarities of the sheep influenced by the herbage; and that if they manage to change the characters of the breed, it can, in a majority of cases, be only for a time, unless the tendencies of the surrounding elements are counteracted, by a constant recurrence to the originators of the flock. "I am sorry," says Little, in his valuable practical observations, "to say, that there are too many examples of those, who thought themselves at the head of improvement in stock, relaxing their exertions, and keeping by their own stock; and the consequence has been, that such stocks have degenerated, become delicate, tender, and diminutive in size; and from no other cause but that the same pains have not been taken to preserve the improvement, that was taken to effect it. I could mention many improvers who were of the first class formerly, but who are now only in the second." Changes, in fact, by crossing are not to be effected in a short space of time; you must look forward to several years of constant exertion, before you can hope, in this manner, to alter your stock.[ [17] Then, again, we must be aware of the tendency which nature, in numerous instances, displays to perpetuate diseases, dispositions, and aberrations from the normal structure. Many qualities and diseases, are known, in man, to be hereditary; of the former, I may instance peculiarities in walking, and writing; a passion for intoxicating liquors, and other habits too trivial to mention; and of the latter, gout, pulmonary consumption, and blindness from cataract, which are well known to harass a family for generations. Features, in like manner, may remain for ages of the same undeviating cast; thus the Jews of to-day are the very counterparts of the Jews of three thousand years back, and, in all likelihood, will so remain till the end of time. A predisposition to many diseases is engendered in the sheep, by too great a refinement in breeding, which tends to diminish the size of the animal, prevents them feeding to perfection, destroys their fecundity, and imparts great tenderness of constitution. Accidental deviations from the natural type may, also, be hereditary, as is seen in those races of dogs which have a supernumerary toe on the hind foot, and tarsal bones to correspond. In the human race also several generations of a particular family have been distinguished, by having six fingers and six toes, on their hands and feet. It is in like manner to an accidental malformation, that the Americans are indebted for their Otter breed of sheep. Mr Livingston, who wrote in 1811, thus describes them: "The Otter sheep were first discovered on some island, on the eastern coast, and have spread to the adjoining states. The sheep are long-bodied rather than large, and weigh about 15 lbs. a quarter. Their wool is of a medium fineness, and a medium length; but that which particularly characterizes these sheep is the length of their bodies, and the shortness of their legs, which are, also, turned out in such a manner as to appear rickety. They cannot run, or jump, and they even walk with some difficulty. They appear as if their legs had been broken and set by some awkward surgeon. They can scarcely exist in a deep country, and they cannot possibly be driven to a distant pasture or market." Dr Dwight, in his travels in New England, remarks of this curious variety, that the fore legs are remarkably short, and bent inward, "so as distinctly to resemble what are called club-feet."[ [18] I believe this to be the only instance where man has availed himself of a defect in the animal kingdom, and turned it to his advantage. Attention ought also to be bestowed on the order in which different parts of the animal are subjected to changes during crossing. These, according to Dr Sturm, the latest observer on this head, are first exhibited in those parts that possess a power of being reproduced, as the hair, horns, and hoofs. The fleshy parts change slowly, in proportion as the mother has much of the blood of the original race. The first changes take place in the head, and are gradually developed towards the hind quarters. Lastly, look to the condition in which your sheep are as regards fatness. If fat, they will be averse to becoming pregnant, and considerable annoyance will, in all likelihood, be experienced. A moderately low diet is most suitable for ewes, for some time before the ram is admitted, in the same way that fruit trees, when unproductive in a rich soil, are rendered fertile by placing straw and stones between their roots and the too nutritious earth. A rather poor diet, also, during pregnancy, will be found to obviate many of those risks which are sure to be incurred from repletion during this period.
(92.) Choice of Parents.—However faulty sheep may be, some are always to be found surpassing their fellows, and these it ought to be the aim of every breeder to discover. Without acknowledge of an animal's points, it is in vain that the breeder can hope for improvement. He may by accident make a lucky hit, but, unless he has studied his business from the bottom, he cannot follow up and avail himself of an advantage, which a more knowing individual would, from previous training, turn at once to a profitable account. Much may be done by letter-press description; and this I shall endeavour to achieve; but more will be accomplished by a close and attentive examination of a few well-selected animals, which it is now no difficult matter to get a view of, as, thanks to the spirited exertions of the Highland Society, valuable specimens are far from rare. In breeding and rearing rams, two divisions of these animals are recognised,—ram getters, and wedder getters,—the former, from their fineness, being kept for the procreation of animals like themselves, while the latter, from their coarseness, are set aside as fitted only for parent stock for grazier's sheep, the mere grazier liking a ram no worse for having a massy frame, and being less scrupulous about his form than the ram breeder, whose grand object is fineness, and who trusts to the ewes for giving the offspring size and substance. The principal ram-breeders are guided in the choice of their ram-lambs, more by blood or parentage, than by form, on which, at so early an age, little dependance can be placed. In the case of the Dishleys, they allow them every indulgence, from the time of weaning till that of shearing, as they push them forward with the intent of letting them the first season, while yet yearlings. It is this early arrival at maturity, which is, with truth, supposed by some to occasion their early falling off; for by a law of the animal economy, premature adult age is always succeeded by premature decay; life appearing to be dated from the time the animal enters on the fulfilment of the ends for which it was created.
According to Mr Bakewell, the shape which should be the criterion of a sheep, is that of a hogshead or firkin, truly circular, with small and as short legs as possible: upon the plain principle, that the value lies in the barrel, not in the legs; and all breeds the backs of which rise in the least ridge are bad. Their bodies should be as true barrels as can be seen, their backs round and broad, and their legs not much exeeeding six inches in length. The following is a measurement of a three-years' old ram of Mr Bakewell,
| Feet. | Inches. | |
| Girth, | 5 | 10 |
| Height, | 2 | 5 |
| Breadth of Collar, | 1 | 4 |
| Breadth of shoulders, | 1 | 11½ |
| Breadth across the ribs, | 1 | 10½ |
| Breadth across the hips, | 1 | 9½ |
A most unusual proof of kindly feeding in the animals of this shape, is their feeling quite fat, just within their fore legs, on the rib; a point in which sheep are seldom examined, from common breeds never carrying fat there. They are particularly distinguished by the lightness of the offal, the bones being one-half smaller than in some other breeds, and the meat proportionally thicker, while the pelt is thin, and the head small—a thing of some consequence in most parts of England, where that Scottish luxury, sheep-head broth, is so cordially despised.
The best form for a cheviot ram is thus described by Mr Cully, in his excellent work on Live-Stock: "His head should be fine and small; his nostrils wide and expanded; his eyes prominent, and rather bold or daring; ears thin; his collar full from his breast and shoulders, but tapering gradually all the way to where the neck and head join, which should be very fine and graceful, being perfectly free from any coarse leather hanging down; the shoulders broad and full, which must at the same time join so easy to the collar forward and chine backward, as to leave not the least hollow in either place; the mutton upon his arm or fore-thigh must come quite to the knee; his legs upright, with a clean fine bone, being equally clear from superfluous skin and coarse hairy wool from the knee and hough downwards; the breast broad and well forward, which will keep his forelegs at a proper wideness; his girth or chest full and deep, and instead of a hollow behind the shoulders, that part by some called the fore-flank, should be quite full; the back and loins broad, flat, and straight, from which the ribs must rise in a fine circular arch; his belly straight; the quarters long and full, with the mutton quite down to the hough, which should neither stand in nor out; his twist deep, wide and full, which, with the broad breast, will keep his four legs open and upright; the whole body covered with a thin pelt, and that with bright soft wool. The nearer any breed comes up to the above description, the nearer they approach towards excellence of form." As an amusing contrast to this well drawn picture, I give an extract from the work of that ancient agriculturist Columella.
"Therefore, the way to judge and approve of a ram, is not only that of observing if he is clothed with a white fleece, but also if his palate and tongue are of the same colour with his wool; for when these parts of his body are black or spotted, there arises a black or speckled offspring. And this, among other things, the same poet I mentioned above, (Virgil, Georg. Lib. iii.) has excellently pointed out in such numbers as these:"
