The name given to this hound is founded upon his peculiar power of scenting the blood of a wounded animal, so that, if once put on his trail, he could hunt him through any number of his fellows, and would thus single out a wounded deer from a large herd, and stick to him through any foils or artifices which he may have recourse to. From this property he has also been used to trace human beings; and as his nose is remarkably delicate in hunting, even without blood, he has always been selected for that purpose, whether the objects of pursuit were slaves, as in Cuba, or sbeep-stcalers, as in England.
Fig. 7. - HEAD OF BLOODHOUND.
At present there are, as far as I know, no true bloodhounds in England for this purpose, or indeed for any other, as I believe the breed to be extinct; but several gentlemen possess hounds commonly called bloodhounds, though only partially resembling the veritable animal, and use them for hunting fallow-deer, especially those which are only wounded with the rifle, and not killed outright. This dog is also kept for his fine noble appearance; and as his temper is generally less uncertain than the genuine old bloodhound, and his taste for blood not so great, though still sometimes beyond all control, he is not unfitted to be the constant companion of man, but must always be regarded with some degree of suspicion. Bloodhounds, more or less purely bred, are still plentiful in the Southern States, where formerly considerable packs were kept for hunting both deer and fugitive slaves.
The following are the distinctive marks of this dog, which should make their appearance even when one only of the parents is thorough-bred: - Hight, from 24 to 25 or even 26 inches; peculiarly long and narrow forehead; ears from 8 to 9, and even 10, inches long; lips loose and hanging; throat also loose, and roomy in the skin; deep in the brisket, round in the ribs, loins broad and muscular, legs and feet straight and good, muscular thighs, and fine tapering and gracefully waving stern; color black-tan, or deep and reddish fawn (no white should be shown but on just the tip of the stern); the tongue loud, long, deep, and melodious, and the temper courageous and irascible, but remarkably forgiving, and immensely susceptible of kindness. The illustration is a portrait of the fine head of a dog owned by Mr. Reynold Ray, an old and well-known breeder, and a prize-winner at various shows.
