Rob did not bother trying to communicate this to Andy, for there was no need, and it would hardly have been politic, with the man outside so close to them. He was now at the next window, and Rob believed that the crisis was at hand, for the man gave a satisfied grunt as though things were finally working to suit his purposes.

So he nudged Andy, as if to warn him to be on the alert, though truth to tell there was little need of this, for the other scout was fully aroused every second of the time, with his gun clutched in nervous hands ready to do his duty when the call came.

Yes, the window was being shoved back now, and the man still muttered to himself. One thing sure, he never dreamed that the cabin had occupants, though how the door came to be fastened on the inside must have puzzled him somewhat.

The eyes of the boys had become so used to the semi-darkness that they were able to fairly make out the window, once the shutter had been drawn back. They could also see some sort of movement there. Having given the swinging sash a push that sent it inward, the man was now thrusting his head and shoulders through the small opening.

Rob knew the difficulties attending such an awkward entrance. He felt almost certain that the party, even if not clumsy in his movements, would likely tumble to the puncheon floor when he finally gave the last push. That was the very moment Rob figured on springing his surprise. The man would be caught unawares, and least able to defend himself or spring at them.

When he heard a scuffling sound, and saw the window no longer obstructed by a dark form, Rob knew the crisis was upon them.

CHAPTER X
NEATLY DONE

As the scout master suddenly pressed the button of his little hand torch and threw the expanding ray of light straight ahead, he called out in a loud voice:

“Go to it, Tubby, Andy!”

There was a loud crash. Tubby had obediently thrown the wooden fire screen over to the floor, and was trying to snatch up some of the fine tinder that would burst into a brilliant flame almost as soon as it reached the still hot embers on the hearth.
