“Well, the boards have been taken out some feet toward the opposite side of the sag, haven’t they?”

“Hum—yes, that’s so.”

“Well, then, there’s your upward curve before you come to the gap.”

“Jiminy cricket, Lathrop, you are right. Now, what’s your plan—to leap the gap?”

“Yes, but we must lighten the auto. We all have cool heads, and we can stand on the edge of the gap and throw most of the heavy things in the car across the space. Then we can pick them up on the other side. That is, if we get the auto over.”

Even Bart Witherbee had to agree that the plan looked feasible. All of the party, with the exception of old Mr. Joyce, had seen the same feat performed in a circus. True, in the show everything was arranged and mathematically adjusted, but the conditions here, though in a rough way, were yet the same practically. There was the descent, the steep drop, the short up-curve and then the gap. The more they thought of it the more they believed it could be done.

It did not take long to transfer most of the heavy baggage to the other side of the gap, and then came Lathrop’s next order—which was that the others should shin themselves across the stringpieces to the opposite side of the gap, so that the auto might not be burdened with their weights. It took a lot of persuasion to make them do it, but they finally obeyed, and Lathrop alone walked back up the trail to where the auto stood with its brakes hard set.

The boy himself would not have denied that his heart beat fast as he approached the car. In a few minutes he was to make an experiment that might result in certain and terrible death if the slightest hitch occurred.

But he thought of his chums marooned and in the hands of their enemies on the other side of the canyon and the reflection of their peril steeled him to endure his own.

The boy took a quick glance all about him.
