On issuing from their place of confinement, the whole party instantly experienced a grateful renovation of spirits, by exchanging the pent air of the hiding-place for the cool and invigorating atmosphere which played around the whirlpools and pitches of the cataract. A heavy evening breeze swept along the surface of the river, and seemed to drive the roar of the falls into the recesses of their own cavern, whence it issued heavily and constant, like thunder rumbling beyond the distant hills. The moon had risen, and its light was already glancing here and there on the waters above them; but the extremity of the rock where they stood still lay in shadow. With the exception of the sounds produced by the rushing waters, and an occasional breathing of the air, as it murmured past them in fitful currents, the scene was as still as night and solitude could make it. In vain were the eyes of each individual bent along the opposite shores, in quest of some signs of life, that might explain the nature of the interruption they had heard. Their anxious and eager looks were baffled by the deceptive light, or rested only on naked rocks, and straight and immovable trees.
