yed the location of Rock Haven.

"Oh, this is lovely!" said Eleanor. "I'm so glad you brought us here,
Mr. Trenwith! But tell me, doesn't anyone live on this island? It's so
beautiful that I should think someone would surely have built a summer
home there long ago."

"I believe there are people there," said Trenwith. "But they are on the
other side."

"I'm sorry we have to go home, but I suppose we really must be
starting," said Eleanor, after supper. "It's such a heavenly night that
it seems to me it would be perfect just to stay here."

"Wouldn't it? But you're right--we must be starting back. We'll go on
and come around the other side of this island. You should see it from
all points of view. Scenically, it's our show place for this whole
stretch of coast."

And so as soon as Bates had finished clearing off the table he went back
to his engine, and the _Columbia_ slipped along smoothly in the
shadow of the island. But a few minutes later, as they were gliding
along on the seaward side, where the water was far rougher, there was a
sudden jar, and the next moment the engine stopped.

"Why, what's the matter!" asked Eleanor, surprised.

"Nothing much, probably," said Trenwith "Bates will have it fixed in a
few minutes. The best engine in the world is apt to get balky at
times--and I must say that mine has chosen a very good time to
misbehave."

Eleanor chose to ignore the meaning he so plainly implied, but she was
perfectly content with the explanation, and sat there dreamily,
expecting to hear the reassuring whir of the motor at any moment. But
the minutes dragged themselves out, and the only sound that came from
the engine was the tapping of the tools Bates was using. Trenwith
frowned.

"This is very strange," he said. "We've never been delayed as long as
this since I've had Bates. He usually keeps the motor in perfect running
order. I'll just step forward and see what's wrong."

He returned in a few moments, his face grave.

"Bates has some highly technical explanation of what is wrong," he said,
seriously. "It seems that he needs some tools he hasn't got, in order to
grind the valves. I'm afraid we'll have to get ashore somehow--he seems
to be sure that he can find what he is looking for there."

Eleanor looked rather dismayed.

"It's going to make us terribly late in getting ashore, isn't it?" she
asked. "I'm afraid the others will be worried about us."

"No. Bates says that as soon as he gets the
