Luckily he rolled in, and not out, or he would have rolled to the edge of the ship. Not that he could have gone overboard, for there was a railing and netting to stop that, but he would have been badly frightened if he had rolled near the edge, I think.

“Look out!” cried Mr. Bobbsey, as he saw Bert sliding and slipping. “Look out, or you’ll fall downstairs!”

And that is just what happened. Bert rolled to the top of the companionway stairs, and right down them. Luckily he was a stout, chubby boy, and, as it happened, just then a sailor was coming up the stairs, and Bert rolled into him. The sailor was nearly knocked off his feet by the collision with Bert, but he managed to get hold of a rail and hold on.

“My! My! What’s this?” cried the sailor, when he got his breath, which Bert had partly knocked from him. “Is this a new way to come downstairs?”

“I—I didn’t mean to,” Bert answered, as he managed to stand up and hold on to the man. “The ship turned upside down, I guess, and I rolled down here.”

“Well, as long as you’re not hurt it’s all right,” said the sailor with a laugh. “It is certainly a rough storm. Better get below and stay there until it blows out.”

“Yes, sir, I’m getting,” grinned Bert.

“I think that is good advice,” said Mr. Bobbsey to the sailor, with a smile, as he hurried after Bert, but not coming in the same fashion as his son.

Nan had grabbed tightly hold of a rope and clung to it when the ship gave a lurch. She was not hurt, but her arms ached from holding on so tightly.

After that one big roll and toss the steamer became steady for a little while, and Mr. Bobbsey and the two children made their way to the stateroom where Mrs. Bobbsey was sitting with Flossie and Freddie.
