“No, indeed,” said both girls.

“I think I ought to take the watch. This is partly on my account,” said Bessie.

“Sleep first, and perhaps you can take the second spell, with Dolly,” said Eleanor. “You’ve had a harder day than the rest of us, and you must be tired now.”

Bessie and Dolly were, indeed, very tired. The fact that the camp was not to be left unguarded while they slept seemed to reassure Dolly, and she and Bessie were soon sound asleep. Only the noise of the light surf disturbed the intense stillness, and that had a soothing, musical quality that made it far from a disturbance to those who slept.

But that peace was to be rudely shattered before the first watch was over. It was just after midnight when a wild tumult aroused the camp, and Bessie and Dolly, springing to their feet, saw that the beach was as light as day—and that the light did not come from the camp fire. Confused and sleepy as they were, they saw the cause in a moment—the big living tent, in which meals were to be eaten in case of rainy weather, was all ablaze, and the wind that had sprung up during the night was blowing the sparks to the other tents, which caught fire as the girls, frightened and almost panic stricken, rushed out.

For a moment there was no concerted effort, but then Eleanor took command of the situation, and in a moment a line had been formed, and pails full of water from the sea were being handed from one girl to another.

The yacht had sprung into life at the first sign of the fire, and now, as the girls worked, they heard the sound of oars, as boats were hurriedly pushed ashore. In a minute a dozen men had joined them in their fight against the fire, and, thanks to this unexpected aid, one or two of the tents, which had been furthest from the one in which the blaze had started, were saved.

The men from the yacht worked heroically, but their presence and their shouts created a new confusion. And in the midst of it Bessie, a pail of water in her hand, saw a man seize Zara and carry her, struggling, toward a boat. She was just about to cry out when a hand covered her mouth, and the next instant she was lifted in strong arms, carried to the boat, and pushed in.

Then two men sprang aboard, and one held the girls, while the other pulled quickly toward the yacht. They were prisoners!
