"You know that the Captain is quite a collector, and in his travels has gotten together among many other things some interesting books. He gives them to me when convenient." The face of the lanky shepherd was perfectly grave when he spoke of Captain Broom as a collector.

"What makes the water so clear around here?" asked Juarez. "I never saw anything like it."

"Well, you see," replied their mentor, "this island is placed peculiarly, I mean this side of it. You see how quiet the water is?"

"It is certainly smooth and blue," said Juarez. "More like a lake than the ocean."

"That's only true of this side," resumed the shepherd, "the other is rough enough, but you see the prevailing winds are from the Northwest and this shore is never disturbed. So on the beaches you will find not sand, but smooth round pebbles, because there is no action of the water, no breakers or waves to grind them into sand."

About four o'clock the Sea Eagle came into a perfectly beautiful little harbor, at the South-eastern end of the island. There was a small level plot back from the beach and on all sides rose steep hills and back of them the mountains. It was the most picturesque scene the boys had ever beheld in all their travels.

What would they not have given to have been free to roam that island, hunting inland, or fishing or bathing along those quiet, enchanted shores. But this was no pleasure excursion. Far from it. Captain Broom had his own ideas, and he did not intend to make a landing at all.

"Get the whale boat ready, lads!" he ordered. "And put her over, we've got no time to lose."

They lost no time either, under Captain Broom's commanding eye.

What was necessary for the cruise was already in the boat. Two casks of water, several guns, and a lot of provisions. Then the boat was hove overboard into the quiet bay. The captain was ready with a much battered satchel in his hand. Not for one second did he entrust it to any one else.
