Suddenly the sound ceased; the plane's motor had been shut off. Almost at the same instant the light‑ray picked up the plane. It was several thousand feet in the air and almost over our heads, coming down in a spiral. A moment more and the light‑ray swung away.

The plane burst into flame, and I knew it was falling. An explosion sounded near at hand. The camp was in chaos immediately. I faced about to look at Tao; he had disappeared.

I waited no longer. Turning back from the river, I ran at full speed.


[ CHAPTER IX.
FUTILE ATTACKS.]

There seemed to be no pursuit. In a few moments I was clear of the camp and hidden in the darkness of the desert. I ran perhaps half a mile, then I slowed down to a walk, completely winded. Turning, I could see behind me the lights of the camp. I doubted if even now they had missed me. The bomb dropped by the airplane and the plane itself falling almost, in their midst must have plunged them for the time into confusion.

I kept on walking rapidly. The desert here was almost pathless; occasionally I would cross a wandering wagon track, but none of them seemed going in my direction. After a time I was not sure what my direction was; all about me was a luminous darkness—and silence.

I found myself now almost exhausted from my exertions of the day. I decided to go possibly a mile farther—to be well away from the Mercutians—and then to lie down and sleep until daylight.

In about fifteen minutes more I concluded I had gone far enough, and, lying down on the sand, was soon fast asleep. When I awoke it was daylight, with the sun just rising.

With returning consciousness I looked about me in sudden fear, but there was no one in sight. I ate the bread and meat I had in my pocket, and, feeling much refreshed, but thirsty, I started again for Garland.
