"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."
