the island. You will be all right with them, won't you, dear?"

"Of course," replied the twin, rather confusedly. "I don't need
attention."

"But you are tired," put in Cora, "and those girls have not done a
thing since lunch time. Just command them."

"'Very well. But do be careful, you two girls. A bad beginning you
know."

"Oh, don't you worry about us," replied Cora confidently. "I feel
as if this boat was a top in my hands. It is so much easier to
handle than an auto. No gears, differentials or things like that.
Good bye, Belle. Have supper ready when we return," and she sounded
the small whistle that told of the start again.

"Good bye. Be careful," cautioned Belle. Then the two girls headed
the craft for the little island around which they had just seen the
boys disappear.

"I thought the boys looked very serious," said Bess, as she put her
hand on the wheel Beside Cora's. "I wonder what is wrong?"

"Jack certainly had something very important on when he neglected
me," said his sister. "I hope there is nothing really wrong. There
are no people on that island, I believe."

"Then perhaps we had better not land?" suggested Bess. "It might be
horribly lonely and we might not be able to find the boys."
