"What a nuisance!" Dick whispered. "He is evidently going on sentry duty."

"Perhaps he has gone to the gate?" Surajah suggested.

"I am afraid not. I expect the other hut is furnishing the sentry there. Listen!"

During the pauses of the low conversation of the two men still sitting by the fire, they could hear a footfall outside.

"That settles the question," Dick said. "Now, the sooner those fellows go to sleep, the better."

"We had better wait for some time, after they do," Surajah replied. "One or two of the men, who lay down first, are sure to get up and go to the door and look out. They always do that, once or twice during the night. The sentry will soon get accustomed to the door being opened, and won't look round sharp."

"That is a good idea," Dick agreed. "The moon is at the back of the hut, so we shall be in the shadow. I will spring upon him, and will try and grip him by the throat, so that he can't holloa. You wrench the musket from his hands, and snatch his belt of cartridges. That will give us a weapon, anyhow. As soon as you have got it, I will give him one sharp squeeze, and throw him down. It will be some time before he gets breath enough to holloa."

In half an hour, the two men by the fire lay down. It was not long before, as Surajah predicted, one of the sleepers sat up and stretched himself; then he rose and walked to the door, opened it, and stood at the entrance; a moment later he was joined by another figure, and for a few minutes they stood, talking together. Then he came in again, shut the door, and lay down.

During the next hour, three of the others followed his example, the last of them leaving the door ajar behind him, when he came in.

"Now is our chance, Surajah. We must give him ten minutes to fall asleep again. Then we will move. Should one of them be lying awake, and notice us--which is not likely, for it is too dark in here to see figures distinctly--and ask where we are going, say, 'To the door, to get cool.' They won't imagine that we are thinking of escape, with one sentry at the door, and another at the gate."
