“I rather like the idea, and ask to be appointed the first keeper of the watch,” spoke up Will.
An arrangement was soon completed. By means of a system each of the boys would be on duty as a guard two hours of the night. This would cover the time from ten to six, which allowed the sleepers ample time to recuperate.
They passed a pleasant evening despite the many suspicious glances cast aloft from time to time. Finally Jerry began to yawn.
“Say, fellows, as I’m the last to go on duty, I guess I’ll turn in. To-morrow I mean to collect a lot of hemlock browse for a bed; but to-night it’s me on the cold, hard ground, with only my good blanket under and above.”
“Not a bit of it, old chap. Here’s where my surprise comes in. Now, you and our good friend Bluff here have been sighing for a chance to prove which one possesses the biggest lungs. I’m going to give you a chance to make good,” announced Frank.
“Hurrah! count me in, whatever it is,” exclaimed Bluff, jumping up, as Frank began to undo the mysterious bundle that had excited their curiosity earlier.
“Here you see a couple of the finest rubber air-cushion mattresses ever made for the use of campers. Each can be extended so that two can sleep on it. Now, I’m going to spread these out here ready. You two will lie down on your chests, and wait till I give the signal, and then blow for all you’re worth. The first one whose mattress is filled with air will be proclaimed the victor,” said Frank.
Jerry and Bluff threw themselves prostrate instantly, eager for the trial, and each filled with a determination to settle the matter for all time. They did not see the sly wink Frank gave Will, nor hear the chuckling sound of amusement that escaped from the lips of that camper as he half turned his head away.
“Go!”
Frank stood there as referee and timed the contestants, who puffed and blew with all the vigor of their young lungs, until both mattresses stood out just as full as they could stand.
