the spray at the base was still there, seeming always to rise while the restless water seemed motionless. No trace that human beings had ever invaded these solitudes could he discover. No vague, faint suggestion of the well-hidden lair of the moonshiners did the wild covert show forth. “The revenuers war smarter'n me; I'll say that fur 'em,” he muttered at last as he came to a stand-still, his chin in his hand, his perplexed eyes on the ground. And suddenly--a footprint on a marshy spot; only the heel of a boot, for the craggy ledges hid all the ground but this, a mere sediment of sand in a tiny hollow in the rock from which the water had evaporated. It was a key' to the mystery. Instantly the rugged edges of the cliff took on the similitude of a path. Once furnished with this idea, he could perceive adequate footing all adown the precipitous way. He was not young; his habits had been inactive, and were older even than his age. He could not account for it afterward, but he followed for a few paces this suggestion of a path down the precipitous sides of the stream. He had a sort of triumph in finding it so practicable, and he essayed it still farther, although the sound of the water had grown tumultuous at closer approach, and seemed to foster a sort of responsive turmoil of the senses; he felt his head whirl as he looked at the bounding, frothing spray, then at the long swirls of the current at the base of the fall as they swept on their way down the gorge. As he sought to lift his fascinated eyes, the smooth glitter of the crystal sheet of falling water so close before him dazzled his sight. He wondered afterward how his confused senses and trembling limbs sustained him along the narrow, rugged path, here and there covered with oozing green moss, and slippery with the continual moisture. It evidently was wending to a ledge. All at once the contour of the place was plain to him; the ledge led behind the cataract that fell from the beetling heights above. And within were doubtless further recesses, where perchance the moonshiners had worked their still. As he reached the ledge he could see behind the falling water and into the great concave space which it screened beneath the beetling cliff. It was as he had expected--an arched portal of jagged brown rocks, all dripping with moisture and oozing moss, behind the semi-translucent green-and-white drapery of the cascade. But he had not expected to see, standing quietly in the great vaulted entrance, a man with his left hand on a pistol in his belt, the mate of which his more formidable right hand held up with a steady finger on the trigger.
