"They are there!" cried Will. "I'm sure they're there, and alive!"
"But they can't live there very long!" suggested Ed. "So we'd better be doing something to get them, out!"
"The first thing to do," Will stated, "is to signal to the other fellows. I'm sure Tommy and Frank must be in with the surgeon before this!"
"There'll be plenty of work for the surgeon, I imagine," Ed added.
"I'm afraid so," Will admitted.
"But how are you going to signal to the cabin?" asked Ed.
"Indian smoke signals!" was the reply.
Almost before the words were out of Will's mouth, Ed was gathering both dry and green branches from the thicket.
"If the boys are at the cabin, or even on their way there," Will continued, "they'll be sure to see the signal, for the night is not so very dark now, and the land where we are is considerably higher than the moraine upon which the cabin is built. We'll have to get a blazing fire of dry wood and then pile on green branches."
"That ought to make a smudge visible ten miles off!" said Ed.
