Presently there came to our ears a roar with an undertone which spoke a language now familiar, and we kept as close to the right bank as possible, so that a stop could be instantly made at the proper moment.

When this moment arrived a landing was effected for examination, and it revealed a furious descent, studded with large rocks, with a possibility of safely running through it if an exact course could be held, but the hour being now late a camp was made at the head and further investigation deferred till the next morning.
This morning was Sunday, and the sun shone into the canyon with dazzling brilliancy, all being tranquil except the foaming rapid.

The locality was so fascinating that we lingered to explore, finding especial interest in a delightful grotto carved out of the red sandstone by the waters of a small brook.

The entrance was narrow, barely 20 feet, a mere cleft in the beginning, but as one proceeded up it between walls 1500 feet high, the cleft widened, till at 15 rods it ended in an amphitheatre 100 feet in diameter, with a domed top.

Clear, cold water trickled and dropped in thousands of diamond-like globules from everything.
