“He was pretty sure to do that sooner or later, but it rarely availed against the marvelous scent of his enemies. After a time the man had to leave the creek or river, as it might be, and with two or three or more bloodhounds trotting along the bank with their muzzle to the ground, they were certain to pick up the scent with little or no loss of time.

“This peculiarly Spanish product became famous during the war with the Seminole Indians of Florida some seventy years ago. You know that those redskins retreated into the swamps and everglades where our soldiers could not follow them, or, if they followed, could not find them. The war dragged on year after year until the patience of the government was worn out. In its perplexity a number of Cuban bloodhounds were imported; and, although our officers took pains to declare that the dogs would be used to track and not to rend the Seminoles, an indignant protest went up against the barbarity of the act.

“But,” added young Burton with a laugh, “the crime, if it were such, worked its own remedy. Somehow or other the Indians learned to make friends with the black brutes which came to them in the swamps, and they trained them with so much skill that they used them to hunt down the stray soldiers and former owners. The use of bloodhounds in the Seminole war proved a farce.”

It was neither a bark nor a growl, but a mixture of the two,—a deep howl that might well fill a fleeing fugitive with shivering fear.

“That’s Zip,” said his pleased owner; “he will be here in a few minutes.”
