"Please, no!" I begged. Never had I seen such beasts. They were darkly colored, usually brown, and some were black. They were, some of them, as much as twenty feet in length. Several must have weighed between twelve and fourteen hundred pounds. They were six legged, clawed, and doubly fanged. Their heads were wide and triangular, like those of vipers, but their bodies, long and sinuous, were thickly furred. They twisted and squirmed about one another. I had been held by the two men at the edge of the barrier, to see the attack on the first piece of lowered meat. The animals leaped for it, some of them thirty or more feet into the air. Some even caught and clung to it as it was being lowered, tearing at it and cutting at it with their hind pairs of feet. There was a stink in the place of the animals, and the noise of their snarling, their hissing, their squealing and challenge screams was ear-piercing and horrifying.
