Frightful as was the scene, it might yet prove our salvation if the ship could escape colliding with the precipitous walls. Were there no abyss we would certainly be dashed to pieces on the earth itself.

Suddenly the ship heeled over fifty degrees, flinging its living freight violently against the houses on deck and the lower rail. But we were saved! One side of the deck grazed the precipice as it plunged into the cañon. We had passed through the danger before knowing what had happened.

Lyone was stunned, but safe, the captain had a dislocated wrist, and others had broken limbs, but none was fatally hurt.

It was a terrible experience.

As the cañon of the river led in a northeasterly direction we did not emerge from the shelter it gave us to seek fresh conflict with the cyclone, but kept flying between the formidable walls. We soon knew by the returning sunlight and the silver clouds that the hurricane had died away.

The damage done to the Aeropher was quickly repaired. The ceaseless humming of the fans revolving on axles of hollow steel lulled our senses once more into dreamy repose.

"Ah," said Lyone, "this is life. I feel as though I were a bird or disembodied spirit. This aerial navigation is the realization of those aspirations of men that they might like birds possess the sky. Some have wished to enjoy submarine travel, to explore those frightful abysses of ocean where sea-monsters dwell; to behold the conflict of sharks in their native element, to see the swordfish bury his spear in the colossal whale. I prefer this upper sphere of sunlight and the dome of forests, mountains, and valleys of the dear old earth."

"You are right," said I; "the world into which we are born is our true habitat."

The walls of the cañon grew wider apart until we floated in a valley two miles wide. The meadow land below us was carpeted with grass and covered with clumps of forest trees, down the middle of which ran the river, green and swift. The walls of the valley here rose twelve thousand feet in perpendicular height, prodigies of stone, stained in barbaric colors by the brushes of the ages. Here and there triumphant cataracts flashed from the heights and fell in torrents of foam to the valley below. Sometimes a tributary of the river dashed furiously from the battlements above us into the abyss, flinging clouds of spray on the tops of the trees beneath.
