"All right," he said, "if the saplings will hold up the weight."

"They don't need to," explained Jerry. "The Skyrocket will reach over to the inner edges of the boats; I measured the distance with my eye. All the sticks do is to hold the two ships together."

Phil's crew made two trips, on the second one bringing in Frank, who had wrapped up a weird collection of broken-off parts in a piece of varnish-stiffened silk torn from one of the planes.

It did not take long to load the "body" of the Skyrocket onto the saplings, the boats being still on shore. Then, all pushing steadily, the strange double craft was slowly forced across the sand and into the shallow shore-water of Plum Bun. Both boats settled dangerously near to the point of shipping water, so it was fortunate that the river was as calm as a millpond. At that, there was no hope that anyone could get in to row the boats.

"Strip for action!" shouted Phil. "The boss says we're to swim across.
Likewise, the last one in's a rotten egg."

The splashing that ensued, as ten youngsters plunged in, almost in a body, nearly swamped the boats. After his first shout of alarm, Mr. Fulton waved his hand gayly and shouted:

"Go to it, fellows. If the doctor didn't have my arm in a splint I'd be right with you."

"All right, Scouts," assented Jerry, "but go mighty easy."

They were all good swimmers, and with hardly a ripple they propelled the Skyrocket slowly but steadily toward the shore of Lost Island. As they drew near they saw that they had spectators on both sides, for awaiting them was the girl Phil and Jerry had seen not so long before, but under different circumstances. Now she waved her hand encouragingly.

"Oh, Liz-z-i-e!" shouted Phil, "where's the meat-axe?"
