The small black bear had stopped near the turtle’s nest, and now it uttered a soft grunting squeal of delight. It half raised itself on its hind quarters, looking around warily to make sure it would not have to share the feast with any other of its tribe. Then, quite suddenly, it dropped down on all fours, and lunging forward, began to scoop up the eggs with its paws, smacking its lips greedily.

Dave raised the rifle, took deliberate aim, and—— Just then Hugh pushed the weapon aside with a quick movement of his arm.

“Don’t shoot, don’t shoot it!” gasped the lad, excitedly. “See,—over there in that clump of bushes!”

With a muttered exclamation, Dave glanced in the direction that Hugh was pointing. The others did likewise. They then beheld a sight which was far more interesting and more worth while than that of a harmless animal lying dead upon the sand, victim of Dave’s marksmanship.

Two little black cubs, scarcely larger than terriers, but much rounder, chubbier and more furry, trotted out from the shadow of the dune and waddled toward their feasting mother. As fast as their short legs would carry them, they ran to her side and fell to gobbling up the remaining eggs. When the nest had been emptied, Ursula and her cubs romped together on the moonlit beach, and, finally, walked away, unharmed.

Well pleased with the amusing scene they had witnessed, the hunters returned to their camp site, went to sleep presently, and on the morrow rejoined Captain Vinton on the sloop.

CHAPTER XII.
AT THE LIGHTHOUSE.

On the whole, the boys were enthusiastic about their cruise at the end of the first week. After camping again for a day or two on Palm Island, they sailed idly among innumerable smaller islands, enjoying the fine weather, bathing, fishing, taking photographs, learning how to manage the sloop, and making observations of other ships that passed.

“The Captain says that by running to starboard more we can strike the lee of Elbow Key Light to-morrow,” Norton said, as he and the boys were turning into their bunks at nine o’clock one night. “You know that’s where the sponging fleet work at this time, so, in case of storm, they can shelter under the lighthouse key. How would you like to spend to-morrow night among the spongers, then make camp at Cypress Key afterward?”

All were agreeable save Dave, who grunted his disapproval.
