“You boys had better come inside,” said Professor Strong as he hurried up. “It’s not safe to be here. A sudden lurch of the steamer might hurl you overboard.”
“All right, we’ll come in,” said Mark.
He had scarcely spoken when an extra puff of wind came along, banging the loose things in the open cabin right and left. The wind took Frank’s cap from his head and sent it spinning aft.
“My cap!” cried the youth and started after it.
“Be careful of yourself!” came from the professor, but the fury of the wind drowned out his voice completely.
Bound to save his cap Frank followed it to the rail. As he stooped to pick it up the steamer gave a sudden roll to the opposite side and he was thrown headlong. At the same moment the spray came flying on board, nearly blinding him.
“Stay where you are!”
“He’ll go overboard if he isn’t careful!” ejaculated Mark, and ran after his chum.
“You be careful yourself,” came from Professor Strong, as he too rushed to the rescue.
