It was empty--there were not even oars in it.
Looking about them, they saw a hollow behind some rocks.

To this they ran, crouching close to the ground, and there they sat and consulted.
It was between two and three o'clock the next morning that Maka's eyes, which had not closed for more than twenty hours, refused to keep open any longer, and with his head on the hard, rocky ground of the passage in which he lay, the poor African slept soundly.

On the shelf at the edge of the lake, the other African, Mok, sat crouched on his heels, his eyes wide open.

Whether he was asleep or not it would have been difficult to determine, but if any one had appeared in the great cleft on the other side of the lake, he would have sprung to his feet with a yell--his fear of the Rackbirds was always awake.
Inside the first apartment was Captain Horn, fast asleep, his two guns by his side.

He had kept watch until an hour before, but Ralph had insisted upon taking his turn, and, as the captain knew he could not keep awake always, he allowed the boy to take a short watch.
