Toward noon of the following day we halted to rest our mounts and ourselves. The beasts we hobbled, that they might move slowly about cropping the ochre moss-like vegetation which constitutes both food and drink for them on the march. Thuvia volunteered to remain on watch while the balance of the party slept for an hour.

It seemed to me that I had but closed my eyes when I felt her hand upon my shoulder and heard her soft voice warning me of a new danger.

"Arise, O Prince," she whispered. "There be that behind us which has the appearance of a great body of pursuers."

The girl stood pointing in the direction from whence we had come, and as I arose and looked, I, too, thought that I could detect a thin dark line on the far horizon. I awoke the others. Tars Tarkas, whose giant stature towered high above the rest of us, could see the farthest.

"It is a great body of mounted men," he said, "and they are travelling at high speed."

There was no time to be lost. We sprang to our hobbled thoats, freed them, and mounted. Then we turned our faces once more toward the north and took our flight again at the highest speed of our slowest beast.
