"I cannot agree with Mr. Somervile, in thinking that SCENT depends on the AIR only; it depends also on the soil. Without doubt, the best scent is that which is occasioned by the effluvia, as he calls it, or particles of scent, which are constantly perspiring from GAME as it runs, and are strongest and most favourable to the hound, when kept by the gravity of the air to the height of his breast: for then it neither is above his reach, nor is it necessary he should stoop for it. At such times scent is said to lie breast high. Experience tells us, that difference of soil occasions difference of SCENT; and on the richness and moderate moistness of the soil does it also depend, I think, as well as on the AIR. At the time leaves begin to fall, and before they are rotted, we know that the scent lies ill in covert. This alone would be a sufficient proof, that scent does not depend on the air only. A difference of scent is also occasioned by a difference of motion; the faster the game goes, the less scent it leaves. When game has been ridden after, and hurried on by imprudent sportsmen, the scent is less favourable to hounds; one reason of which may be, that the particles of scent are then more dissipated. But if the game should have been run by a dog not belonging to the pack, seldom will any scent remain.
"I believe it is very difficult to ascertain what SCENT exactly is: I have known it alter very often in the same day. I believe, however, that it depends chiefly on two things; the condition the ground is in, and the temperature of the air; both of which, I apprehend, should be moist, without being wet: when both are in this condition, the scent is then perfect; and vice versa, when the ground is hard, and the air dry, there seldom will be any scent. It scarce ever lies with a north or an east wind; a southerly wind, without rain, and a westerly wind, that is not rough, are the most favourable. Storms in the air are great enemies to scent, and seldom fail to take it entirely away. A fine sun-shiny day is not often a good hunting day; but what the French call jour des dames, warm without sun, is generally a perfect one: there are not many such in a whole season. In some fogs, I have known the scent lie high; in others, not at all; depending, I believe, on the quarter the WIND is then in. I have known it lie very high in a mist, when not too wet; but if the wet should hang on the boughs and bushes, it will fall upon the scent, and deaden it. When the dogs roll, the scent, I have frequently observed, seldom lies; for what reason, I know not; but, with permission, if they smell strong when first they come out of the kennel, the proverb is in their favour; and that smell is a prognostic of good luck.
"When cobwebs hang on the bushes, there is seldom much scent. During a white frost, the scent lies high; as it also does when the frost is quite gone: at the time of its going off, scent never lies: it is a critical minute for hounds, in which their game is frequently lost. In a great dew, the scent is the same. In heathy countries, where the game brushes as it goes along, scent seldom fails. Where the ground carries, the scent is bad, for a very evident reason, which hare-hunters, who pursue their game over greasy fallows, and through dirty roads, have great reason to complain of. A wet night frequently produces good chases, as then the game neither like to run the COVERT, nor the ROADS. It has been often remarked, that scent lies best in the richest soils; and countries which are favourable to horses, are seldom so to hounds. I have also observed, that in some particular places, let the temperature of the air be as it may, scent never lies."
Amidst the various opinions upon the origin and property of scent, the most opposite join issue upon the simple question of doubt; whether the particles of effluvia which constitute what is termed scent, and by which hounds are excited to follow the game, are proper identical parts of the animal's body emitted in exhalations of respiration from the lungs, or by the transpiration of perspirative matter through the skin. This, perhaps, is of too abstruse a depth for the utmost extent of human wisdom to explore with success. The opinion of Somervile seems founded upon the very basis of experimental observation, bettered by the sound judgment, and practical remarks, upon the promoting, or retarding, effects of both the atmosphere and soil; to which one circumstance alone seems to convey additional rays of elucidation. It must be recollected by every sportsman, who has occasionally taken the field with HARRIERS, that, although they have picked the trail for a mile, into the very stubble, fallow, or covert, where the hare is sitting in her form; although they are trying round her in every direction, and even within a very few yards; there is then no more palpable perceptible scent, than when they trailed at half a mile from her form; and when she lays close, it is evident the dog, or dogs, derive no additional advantage from being nearer to her, (in respect to finding,) unless by stealing away, or jumping up, she gets into motion, when the scent is then afloat, and continued as already described.
Whether this enquiry will ever be traced to the source of certainty, is almost immaterial; it is a large field for the speculation of philosophy, and well worthy investigation. From a contemplative review of the operations of nature, it is evidently demonstrated, that there is a secret instinctive principle infused into the whole race of animals, whereby they are impulsively propelled to the propagation of their species, the preservation of their offspring, or an implicit pursuit of their propensities; so that no one shall become too numerous and destructive for the existence of another upon whom they prey, or with which they live in a perpetual state of warfare. It is likewise to be remarked, that the greater likeness we discover in the form of the animal creation, the more we perceive their friendly disposition to each other; because the scent of their bodies afford a pleasing gratification to the sensitive faculty, without exciting the appetite; if it was not for which all-wise dispensation of a superior and invisible Power, the same species would devour each other, and the purposes of the creation would be annihilated by the operation of its own works.
SCHIRROUS
.—The substance or enlargement so called, is an accumulation of obstructed or extravasated lymph, becoming more and more indurated by its stagnant retention. All tumours of this description, either in MAN or beast, should be attended to in their infancy; when warm stimulants, and powerful repellents, may be expected to have a proper effect, previous to their having acquired induration; after which no hope of obliteration can be indulged, but by instrumental extirpation. From the reflection naturally arising upon which, will appear the prudent necessity of paying early attention to swellings and enlargements of every description; that nature may be assisted in her own efforts, and her indications promoted without delay. Those tumours which are hard, and seemingly insensible, not feeling pain upon pressure, are of the indurated and schirrous kind; all swellings, and enlargements, in which there is palpable heat, constant pain, and a shrinking from the touch, denote SUPPURATION, which should be promoted by means of FOMENTATIONS and POULTICES applicable to the purpose; for where there is a well encouraged formation of matter, and a good discharge, there is seldom any disappointment in the expectation of a speedy cure.
SCIATICA
—is a species of RHEUMATISM attacking a horse in one or both hind quarters, which is sometimes so severe, as to render him nearly or quite immoveable in his stall. It will be found enlarged on under the head Rheumatism, where the means of relief are properly pointed out.
