"We don't furnish brains, we just use them," said Sam as he restored the rib to his pocket. "Now, then," he added, "I'm goin' to give this here boat an overhaulin' from stem to stern."
"There isn't anything wrong, is there?" inquired Fred anxiously.
"I told you I can't say yet," answered Sam. "I don't know until I have investigated. Can't expect much when a lot of harem scarem boys are driving such a machine as this is. Had any more trouble since I left you?"
"We haven't had any," answered Fred. "We helped pull a couple of girls out of the river yesterday."
"What was they doing in the river?" demanded Sam, looking up for the first time since the arrival of the boys.
"What most people usually do when they can't swim," answered Fred.
"What was the trouble?" asked Sam.
"The chief trouble was," said Grant solemnly, "that they did not have any alkali heads. Their heads were made of bone and were solid all the way through."
"The worst of it is," broke in Fred, "that they said we were to blame for spilling them into the river."
"Maybe you were," said Sam. "One never knows. Maybe they saw you trying to steer this boat."
