Almost as he spoke the signal shot out its flames and smoke and in less than twenty minutes the scoutmaster was folding his son in his embrace and wildly shaking the hands of his lost scouts.
Glen was not there. He had gone quietly into the tent where he had expected to find his friend Spencer.
"Good old scout!" cried Will, as he wrung his hand. "You've been giving me more worry than all the rest of my children put together, but I forgive everything now you have returned. Wherever you've been I hope this will be a lesson to you and you'll never go treasure hunting again."
Glen's reply was startling.
"There is no need," he said. "The treasure is found!"
"Found again!" shouted Spencer. "Where? In a bread-box?"
"No, sir. No bread-box this time. Found in the heart of Buffalo Mound. It is pouring into Buffalo Hollow now and by this time to-morrow there will once more be a Buffalo Lake!"
With the crowd of people who came from town to see the marvel of the refilling of Buffalo Lake was a skillful surgeon. He examined Matt's scalp-wound.
"I can fix that up with the aid of the scoutmaster's first aid kit," he announced. "You'll need a few stitches but I guess you are man enough to stand that."
