leaves you can and I'll make a
sort of framework."

Bob started up, ready to go off into the forest after leaves, with
the sailor and Mr. Tarbill. As he gazed out to sea, where the big
waves were still rolling, he saw something that caused him to utter
a cry of astonishment.

"What is it?" asked Captain Spark, hurrying to Bob's side.

"There," replied the boy, pointing to some dark object that was
rising and falling on the swell.

"It's a boat! A boat capsized!" exclaimed Captain Spark. "We must
secure it. It's one from the _Eagle_. Probably the one we were
in."

"Shall I swim out to it?" asked Bob. "Perhaps I can tow it in."

"No, the current is setting toward the beach. It will drift in
presently."

CHAPTER XXI

MORE ARRIVALS

All interest in building a hut was temporarily forgotten as the
four castaways watched the slow approach of the boat. As it came
nearer it was seen to be the captain's gig, in which Bob and his
friends had left the ill-fated _Eagle_.

"Do you think there'll be anything left in her?" asked Bob.

"There will, unless she is smashed," replied Mr. Spark. "The
lockers, in which most of the supplies were packed, are water-tight
and securely fastened. This is a piece of good luck, if the boat
is not stove in. She has turned bottom up, but she may still be
sound. She'll soon be here."

When the gig was close enough so that they could wade out to it,
Bob and Tim Flynn rolled up their trousers and went through the
shallow surf. The beach gradually shelved at this point and they
could wade out nearly a quarter of a mile at low tide.

"She's all right, cap'n!" called the sailor, when he and Bob
reached the small craft. "Sound as a dollar, and the lockers are
closed," he added as the boat rolled partly over.

"Good!" cried the commander. "Pull her in as close as you can and
we'll unload her. Then we'll get her above high-water mark. This
boat may save our lives."

"How?" asked Mr. Tarbill.

"Why, when the sea goes down we can leave the island in her."

"Leave the island? Never! I'm on dry land now, and I'm never
going to trust myself in a boat again."

"Maybe you'll think differently after a bit," said the captain.

By this time Bob and Tim had the boat in very shallow water. They
managed to turn it on the keel, and the first thing they saw was
the sail in the bottom. Ropes, fastened to various projections,
had prevented the canvas from floating away.
