story: CHAPTER XXLANDING ON CAVE ISLAND

At the end of a week Dave was more worried than ever. Each day he and his chums went down to the shipping offices and each day returned to the hotel disappointed. Not a word had been heard concerning the missing vessel and those on board.

The _Golden Eagle_ was all ready to sail on her return trip to the United States, but Phil told Captain Sanders to wait.

"Perhaps we'll hear to-day," he said, and this was repeated day after day.

It was very warm and the boys were glad they had brought along some thin clothing. They scarcely knew what to do with themselves, and Dave was particularly sober.

"I suppose Mr. Wadsworth and the rest are waiting to hear from me," he said to his chums. "But what is the use of sending a message when I haven't anything to say?"

Another Sunday passed, and on Monday the boys visited the _Golden Eagle_, and then went with Captain Sanders to the nearest shipping office.

"Something is going on!" cried the senator's son, as he noticed an unusual crowd congregated. "Must be news of some sort."

"Let us find out what it is!" returned our hero, quickly.

"The _Emma Brower_ has been heard from," said a man, standing near. "That's the vessel that was missing, don't you know," he added.

"What of her?" asked Dave.

"Went down in that terrible storm we had about ten days ago."

"Down!" gasped all of the boys, while Captain Sanders looked the concern he felt. , question: where did the Captain find this out?
A:
At the shipping office
