From the utter silence there emerged a deep, regular pat-pat. It was the tread of some animal⁠—the rhythm of soft but heavy pads placed cautiously upon the ground. It stole slowly round the camp, and then halted near our gateway. There was a low, sibilant rise and fall⁠—the breathing of the creature. Only our feeble hedge separated us from this horror of the night. Each of us had seized his rifle, and Lord John had pulled out a small bush to make an embrasure in the hedge.

“By George!” he whispered. “I think I can see it!”

I stooped and peered over his shoulder through the gap. Yes, I could see it, too. In the deep shadow of the tree there was a deeper shadow yet, black, inchoate, vague⁠—a crouching form full of savage vigor and menace. It was no higher than a horse, but the dim outline suggested vast bulk and strength. That hissing pant, as regular and full-volumed as the exhaust of an engine, spoke of a monstrous organism. Once, as it moved, I thought I saw the glint of two terrible, greenish eyes. There was an uneasy rustling, as if it were crawling slowly forward.
