The unwieldy load swayed and threatened to buckle, and more than once they had to set it down and find new holds, but the winding road picked out by Frank Ellery was followed without any serious mishap, until at last they stood on the high bank overlooking the wide stretch of sandy beach beyond which Plum Run rippled along in the sunshine.

"Set her down—gently, now," ordered Jerry. "We'll let her rest here while we bring up our reinforcements—and the rest of our baggage. Phil, you take three Scouts and go back and bring in the wings. Leave Frank there until you've gathered up every last scrap. The rest of us will stay here to figure out some way of getting our plunder shipped safely across to Lost Island."

"Go to it!" urged Phil mockingly. "You've got some job ahead of you. You figure out how a rowboat's going to float that load across—and let me know about it."

"Yes," challenged a new voice, "you do that, and let me know about it too."

Mr. Fulton had stepped unobserved through the border of trees and brush lining the river path.

"Huh!" bragged Jerry. "If that was the hardest thing we had to do, we could use the Skyrocket for a fireworks celebration to-night!"

CHAPTER XIV

PATCHING THE "SKYROCKET"

But Jerry gave no explanation of the method he intended to use in transporting the unwieldy bulk across the narrow stretch of water. While Phil and his helpers disappeared, to bring up the rest of the aeroplane framework, he set his crew to work. The Scout camp, which was something like a hundred feet north, yielded a couple of trappers' axes; with these he soon had two stout saplings cut and trimmed to an even length of thirty feet. In the larger end of each he cut a deep notch, while to the smaller ends he nailed a good-sized block, the nails found in an emergency locker on the Big Four, both it and the Boy Scout boat having been brought down and hauled up on the beach.

The two boats were now laid side by side, twenty odd feet apart. Across the bows he laid the one sapling, across the sterns, the other, so that blocks and notches fitted down over the far edges of the boats. Mr. Fulton at once caught Jerry's idea and nodded his head approvingly.
