There was a quick exclamation from Lester, and looking at him, they saw that he was peering at an object perhaps half a mile away. It was large and vague in the gathering darkness, but Bill’s keen eyes, accustomed to gaze over wide spaces in the West, made it out at once.

“It’s a motor boat!” he exclaimed. “And by jinks! it seems to be in trouble. See how it tosses about. It looks as if it would upset any minute.”

“Those motor boats are always unsafe,” remarked Lester, with the scorn that the master of a sailboat usually feels for any craft driven by machinery. “They’re getting out of order all the time, and a fellow takes his life in his hands every time he goes out in one. For my part give me a sailboat.”

“Can you see how many people are on board of her?” asked Fred anxiously.

“I see only one,” replied Bill, “and he seems to be tinkering with the engine. Wow! but she shipped a lot of water just then.”

“What are we going to do?” asked Teddy. “He 7 may get upset, and if he doesn’t know how to swim, he’ll drown. And even if he were a good swimmer, he couldn’t make the shore in a storm like this.”

“Here’s the answer,” said Lester briefly, as he gave the tiller a twist and gave Fred directions to pull in the sheet. In a moment the boat had changed its course and was bearing down swiftly toward the disabled craft.

“I’m mighty anxious to get to shore,” Lester remarked, “but we’ve got to see what we can do for this fellow first.”

The storm was now full upon them, and the Ariel staggered as the waves beat against her sides. She ploughed along gallantly, however, under the skilful guidance of Lester, riding most of the waves, although now and then her nose would dive through a big one and enough water would come on board to keep Bill and Teddy busy bailing her out. All were thoroughly drenched, but no one thought of his discomfort, so intent were they all on reaching the motor boat, which by this time was absolutely out of control and tossing up and down like a chip in the surging tumult of waters.

The one occupant had given up as hopeless the attempt to fix the machinery. He had caught sight of the Ariel and was waving his hands wildly.
