“They’re still here,” he shouted across the channel.

Jeff, who had kept his engine idling, decided to risk a closer approach in the amphibian whose lower wingspan barely cleared the tops of grass clumps.

“I guess there aren’t any snags to rip the pontoons,” Larry assured him. To get closer would save Larry many trips to and fro in the water.

“Fine!” Larry commented as the amphibian, moving cautiously, came close enough for him to catch a rope and put a loop around the closest truss of the submerged seaplane. Thus he was able to pass the chunks of gum to Jeff, who had his clothes on and pockets for storage.

While the transfer was being made the amphibian’s engine died with unexpected suddenness.

“Golly-gracious!” Larry exclaimed, “I’ll bet she’s out of gas.”

“Can’t tell by the gauge.” Ruefully Jeff upbraided his stupidity in forgetting to see if they had to gas up before the take-off from the estate.

“Now what’s to do?” he wondered.

Larry, too, saw a number of difficulties—perhaps more than did Jeff, because, from Larry’s point of view, due to Sandy’s suspicion of the superstitious pilot, Jeff must not go free with the gems in his pockets, nor did Larry dare be the one to go. If he did, Jeff might be playing a trick, let him get beyond chance of return in time, use some reserve gas and fly away.

“I can’t swim,” Jeff began, considering the ways of escape to some place where they could secure a supply boat with fuel.
