Max had counted on this fact.

Having notified the intruder to keep away from the fireplace under penalty of getting hurt, and feeling that the way was now open to undertake the carrying out of his little scheme, Max returned to the point where he had reached the roof.

The others had seen to it that the balance of his dry stuff was placed where he could lay hands on the same. So Max by degrees dumped all this down after the first lot.

"Now to set it going," he remarked.

"You seem to be having a bully old time up there all by your lonely," said Steve, half enviously.

"Oh, I'm a cheerful worker," Max replied.

He had arranged some of the best of the stuff so that after applying a match he could send it down upon the top of all that had gone before.

"How is it?" asked Trapper Jim, who was standing on something or other, so that his head came above the low, almost flat roof.

"It's burning all right; I can see it taking hold," came the reply from Max, who had been cautiously peering down the gaping chimney.

"Then take this stuff and follow suit," remarked the other, handing up the armful of weeds he had himself gathered.
