igil of the two, and Teddy began to grow
disgusted.

"Nothing doing to-day, I guess," he grumbled. "Somebody's sent a
wireless to the sharks telling them to keep out of sight."

"And after Lester has taken all that trouble in getting a warm welcome
ready for them," mourned Fred.

"It's certainly very ungrateful on their part," grinned Bill.

"The shark who hides and runs away
May live to bite another day."

Teddy was the perpetrator of the lines.

Fred groaned and, as he made a pass at his brother with his unoccupied
hand, asked: "What have we done that such awful stuff should be pulled
off on us?"

"Hi, there!" shouted Bill suddenly. "I saw something just then."

"Hang out the flags," drawled Fred unbelievingly. "Bill saw something."

"He saw the sea, he saw the sky,
He saw the drifting clouds go by,"

chanted Teddy, the irrepressible.

"I'd see a couple of boobs, if I looked over your way," retorted Bill.
"Cut out the chatter and hand me those glasses."

The binoculars were passed over to him, and he turned them on an object
far out to starboard.

"I thought so," he said exultingly a moment later. "I can see the dorsal
fin of a shark out there."

Disbelief vanished before his confident tone, and all looked eagerly in
the direction he indicated.

"Perhaps it's only a floating bit of wood," said Teddy doubtfully, after
a long gaze through the glasses.

"Let Lester look," suggested Bill. "He knows a shark when he sees one."

Lester relinquished the tiller to Bill and took a long, steady look
through the binoculars.

"Bill is right," he announced at last. "It's a shark and a big one too.
I guess we're going to have some sport, after all."

"But how are we going to get a trial at him?" cried Teddy. "He seems to
be going in the opposite direction."

"I guess he won't go far," replied Lester with easy confidence. "This is
probably his feeding ground, and he'll keep going round and round in
lazy circles. We'll get a little nearer to him before we do anything
else."

He retook the tiller and changed the _Ariel's_ course toward the
spot where they had seen the shark.

"Lower the sail, now," he commanded, when they had gone half a mile.
"Just keep up enough to give us steerage way. A shark thinks a boat's
disabled when it isn't moving much, and his instinct teaches him that
the occupants are probably in trouble and his chance of finally getting
them will be better."

"Do you think
