"L-l-l-let the D-d-d-d-dutchman do it," he begged, snuggling down in his blankets.

"No," said Nat firmly, "it's your turn on duty. Come on now, roll out or we'll pull you out."

Finally, with grumbling protestations, the stuttering youth was hauled forth, and, while Nat and Joe turned in, he and Cal went on duty, or "sentry go," as they say in the army.

"Now then," said Cal crisply, as the shivering Ding-dong lingered by the fire with his rifle in his chilled hands, "you go off there to the right and patrol a hundred feet or more. I'll do the same to the left. We'll meet at the fire every few minutes and get warm."

"A-a-all r-r-r-right," agreed Ding-dong, who stood in some awe of the stage driver. Consequently, without further demur, he strode off on his post. Having reached the end of it he marched back to the fire and warmed himself a second. Then he paced off again. This kept up for about an hour when suddenly Cal, who was at the turning point of his beat, heard a startling sound off to the right among the tomb-like forms of the stone trees.

Bang!

It was followed by two other shots.

Bang! Bang!
