The rivers were thronged in many cases with gaily colored birds of many shapes and hues, some silent, others continually giving forth strident cries as they wheeled above the waters or dipped down to snatch their prey from its depths.

Further out on the plain I came upon herds of grazing animals-small deerlike creatures, and a curious animal that looked like a pot-bellied pig with abnormally long hind legs, and that progressed in enormous bounds, after the fashion of a kangaroo. It was a most ludicrous sight, and I laughed until my belly ached. Later I reflected that it was the first time I had laughed-outside of a few short barks of savage satisfaction at the discomfiture of an enemy-since I had set foot on .

That night I slept in the tall grass not far from a water course, and might have been made the prey of any wandering meat-eater. But fortune was with me that night. All across the plains sounded the thunderous roaring of stalking monsters, but none came near my frail retreat. The night was warm and pleasant, strikingly in contrast with the nights in the chill grim hills.

The next day a momentous thing occurred. I had had no meat on , except when ravenous hunger had driven me to eat raw flesh. I had searched in vain for some stone that would strike a spark. The rocks were of a peculiar nature, unknown to Earth. But that morning on the plains, I found a bit of greenish-looking stone lying in the grass, and experiments showed that it had some of the qualities of flint. Patient effort, in which I clinked my poniard against the stone, rewarded me with a spark of fire in the dry grass, which I soon fanned to a blaze-and had some difficulty in extinguishing.
