"You are an American ?" "Yes," Prescott admitted.
"Come and join us.

We have the best bed in this camp." "It looks as if it might be hard," smiled Dick, glancing down at the men.
"Hard, but not so bad, after all," replied the other officer.
"See, we have removed our overcoats and spread them on the ground.
And we have two blankets over us.

Come under the blankets with us, and we shall all be warmer." Dick hesitated.

He wondered if he wouldn't be crowding them out of their none too good protection against the night air.
"If you get in with us," urged the first, "it will make us all warmer." On the face of it that looked reasonable, provided he did not crowd either out under the edge of the blankets.
"Oh, there will be plenty of room," one of them assured him.
"We can lie very close together.

And you have no blanket if you sleep by yourself." So Dick allowed himself to be persuaded.
