It is indeed, a fearful place. The torrent, swollen by the melting snow, plunges into a tremendous abyss, from which the spray rolls up like the smoke from a burning house. The shaft into which the river hurls itself is a immense chasm, lined by glistening coal-black rock, and narrowing into a creaming, boiling pit of incalculable depth, which brims over and shoots the stream onward over its jagged lip. The long sweep of green water roaring forever down, and the thick flickering curtain of spray hissing forever upward, turn a man giddy with their constant whirl and clamor. We stood near the edge peering down at the gleam of the breaking water far below us against the black rocks, and listening to the half-human shout which cam booming up with the spray out of the abyss.
