The slope here was more gradual and all four soon found themselves at the top of the chasm, wet and cold, but on the side where the Boy Scout signal had shown.

"We ought to tell the boys we are coming, hadn't we?" asked Tommy.

He drew his automatic from his pocket as he spoke and pressed the trigger, but there was no explosion.

"Try mine!" advised Doctor Pelton. "I guess I'm the only person who didn't get wet."

As he spoke the doctor fired three quick shots.

"I wonder if they'll answer?" asked Tommy.

"They will if they can," replied Sam. "I don't know your chums, of course, but when a Boy Scout sends up a signal for help and shots are fired, it is only good manners to acknowledge the courtesy."

No answering shots came for a moment, however, for Will and Ed were at that moment some distance away from the place where their automatics had been thrown after having been taken from Cameron and Fenton.

The shots came before long, however, and the party of wet and shivering boys pressed on.

"I'd like to know what the boys are doing so far away from the cabin," Tommy grumbled. "They ought to have sense enough to stay put!"
