"A bit of a blow, maybe," said the Captain. "Now, girls, off with you. I'll just make things snug. You go below, and sleep through it, and you'll come up fresh as paint in the morning."

Tommy grumbled a little, declaring that a storm was impossible with such a clear sky and no wind; but she went below with her sisters, and soon all three were fast asleep in their snug little cabin.

It was perhaps two hours later when Elizabeth awoke suddenly. There were strange noises overhead, and the ship was rolling and pitching with a violence new to her. Every now and then she heard a hoarse shout, and a scurry of feet on deck. The little appointments of the cabin rattled, and presently, as the vessel gave a particularly heavy lurch, the glass water-bottle slipped from its rack, and fell with a crash to the floor.

"What is it?" cried Tommy, sitting straight up in her bunk.

"The sea is rather rough," said Elizabeth quietly, "and has sent the water-bottle spinning."

"It woke me with a start," said Tommy. "My heart is thumping like anything. Is there any danger?"

"Not with Uncle on board," said Mary from the bunk below. "Let's go to sleep again."

They lay down, but to sleep was impossible. Every moment the movements of the vessel became more violent, and they heard great booming noises as the waves broke over the deck. The roar and shriek of the wind was mingled with the creaking of blocks and the shouts of men.

"I can't stand it any longer," said Tommy suddenly. "I'm going up to see. Come along, girls." She sprang out of her bunk and had to clutch the side to prevent herself from being thrown down. The other girls followed her, and she laughed as they staggered and clasped each other.

"What fun!" she said. "We haven't had a real storm before. See who'll be dressed first. You two needn't do up your hair."
