"Gracious!" exclaimed Mrs. Bobbsey, as she struggled to regain her seat.

"What have we struck?" Mr. Bobbsey asked.

"We've struck Hemlock Island," said Captain Craig grimly. "We've fairly bumped into it. I ought to have known I was somewhere near it. We've fairly rammed it, and we're on the rocks!"

"'On the rocks!'" repeated Mrs. Bobbsey. "Are we in danger?"

"That's what I'm going to find out," said the captain. "At least we can't sink, for we're right on shore," and as he spoke the fog blew away for a moment, showing a bleak shore of rocks with hemlock trees a little way up from the beach. "Yes, sir, we ran plumb on the rocks!" muttered Captain Craig, as he stood up and tried to peer through the fog that was now closing in again.


CHAPTER XIX

TWO LITTLE SAILORS

Now it is time for us to inquire what was happening to Freddie and Flossie, the two smaller Bobbsey twins. They had fallen out of the balloon basket when the big gas bag was blown down on Hemlock Island in the storm. But Flossie and Freddie had toppled out on piles of soft, dried leaves, so they were not hurt. But, as Flossie had said, she was soaking wet.

"We ought to have umbrellas," said Freddie, as he felt the drops of rain pelting down. "If we had umbrellas this would be fun, 'cause we aren't hurt from our balloon ride."
