Hal produced one, and, taking it from his friend’s hand, Chester stepped to the back of the tent. Quickly he opened the blade, and made a neat incision in the canvas, finally cutting out a little square. Then he put his eye to the hole and peered out.

There was no one in sight. The guard could be heard pacing to and fro in front of the tent, but apparently there was no guard at the rear.

Chester left his peep-hole and returned to Hal’s side.

“If we can get two of these bicycles out here,” he whispered, “we may be able to get away by a quick dash. Are you willing to take a chance?”

“Sure,” agreed Hal. “Anything is better than sitting here and waiting for I know not what. But do you think we can make it?”

“Well, we can at least try. There doesn’t seem to be a guard in the rear. I am going to cut a big slit in the back. Then we’ll slip the bicycles through it, mount and make a dash.”

“Good!” said Hal.

Quietly Chester slit the canvas in the rear of the tent, making a hole large enough for a man to step through. Quietly the boys each selected a bicycle and pushed it cautiously through the opening.

Once on the outside they drew a breath of relief.

“We’ll have to depend on our luck now,” whispered Chester. “Come on!”
