The fire blazed up encouragingly, and Ned, getting water from the rapids for the coffee, put the pot quickly into the ring of stones.

"Something's going to happen in about a minute," announced Chunky, with an air of great wisdom. He had been watching the preparations with hands thrust deeply into his pockets.

"What's going to happen?" demanded Ned, turning on him sharply.

Chunky, instead of replying, leaned back against the rocks and began to whistle. In a moment the disaster that he had foreseen was upon them.

The flimsy pile of brush and vines, after the fire had burned away its foundations, gave way beneath the weight of the stones. Coffee pot, coffee and stones went down with a crash and a clatter.

"Save the coffee pot!" shouted Ned, giving Chunky a push.

"Save it yourself. I'm not the cook," answered the fat boy, who chanced to be nearest to the fire. "I told you something was going to happen."

In the meantime Tad Butler had sprung to the rescue. With one well-directed kick he had scattered the brush and rescued the coffee pot before serious damage had been done to it.

Rushing to the river, he scooped up a fresh supply of water, planting the pot in the center of the fire and heaping the burning stuff about it.

"We'll have some coffee after all," he glowed. "I don't think Ned is much of a cook, do you, Chunky?"
