Note 23 — Chapter VI

But, independently of these obvious reasons, scent is affected by causes into the nature of which none of us can penetrate. There is a contrariety in it that ever has puzzled, and apparently ever will puzzle, the most observant sportsman—whether a lover of the chase or gun,—and therefore, in ignorance of the doubtless immutable, though to us inexplicable, laws by which it is regulated, we are contented to call it "capricious." Immediately before heavy rain there frequently is none. It is undeniable that moisture will at one time destroy it—at another time bring it. That on certain days—in slight frost, for instance,—setters will recognise it better than pointers, and, on the other hand, that the nose of the latter will prove far superior after a long continuance of dry weather, and this even when the setter has been furnished with abundance of water—which circumstance pleads in favor of hunting pointers and setters together. The argument against it, is the usual inequality of their pace, and, to the eye of some sportsmen, the want of harmony in their appearance. Should not this uncertainty respecting the recognition of scent teach us not to continue hunting a good dog who is frequently making mistakes, but rather to keep him at "heel" for an hour or two? He will consider it a kind of punishment, and be doubly careful when next enlarged. Moreover, he may be slightly feverish from overwork, or he may have come in contact with some impurity,—in either of which cases his nose would be temporarily out of order.
