It was by no means an easy matter to establish ourselves in that lonely place. The river, though not remote from civilisation, is practically inaccessible for nine miles of its course by reason of the steepness of its banks, which are long, shaggy precipices, and the fury of its current, in which no boat can live. We heard its voice as we approached through the forest, and could hardly tell whether it was far away or near.

There is a perspective of sound as well as of sight, and one must have some idea of the size of a noise before one can judge of its distance. A mosquito's horn in a dark room may seem like a trumpet on the battlements; and the tumult of a mighty stream heard through an unknown stretch of woods may appear like the babble of a mountain brook close at hand.

But when we came out upon the bald forehead of a burnt cliff and looked down, we realised the grandeur and beauty of the unseen voice that we had been following. A river of splendid strength went leaping through the chasm five hundred feet below us, and at the foot of two snow-white falls, in an oval of dark topaz water, traced with curves of floating foam, lay the solitary island.
