the consequent experiences of the "Sister Sue's" passengers.

"It was purely good luck, sir," answered Harriet modestly.

"It was something a great deal stronger than luck," answered the
captain. "The sea is going down. As soon as it is down enough to be
safe I will put you all aboard the cutter."

"Are you going to leave the sloop?" asked Miss Elting.

"No. We want that boat for reasons of our own. We wish to look it over
at our leisure. Your sea anchor saved you, that and good seamanship.
Miss Burrell, it is a pity you are not a man. You would be commanding
a ship in a few years. I think we had better transfer you now. I'm
afraid of the sloop."

The transfer was a thrilling experience for the Camp Girls. Several
times they narrowly missed being upset and thrown into the sea, but
after more than two hours' work everyone had been safely landed on
the deck of the revenue boat. Three men were put aboard the sloop, a
lifeboat being left with them in case the "Sue" foundered. The revenue
cutter then started towing her toward home. It was late in the evening
when finally they came to anchor off Camp Wau-Wau. The surf was
running so high that it was decided not to put the girls ashore until
the following morning, though the "Sue" was cast off from her tow and
allowed to drift into the bay. From here her crew rowed ashore and
informed the anxious Camp Girls that everyone of their companions was
safe.

But the morning brought with it a further surprise. The cabin in which
the Meadow-Brook Girls had made their home had wholly disappeared.
With it had gone the bar, swept out by the storm, the cabin lying a
hopeless, tangled wreck on the shore of the bay. With it, too, had
gone ashore a variety of stuff which the officers of the revenue boat
examined early that morning. They pronounced the ruined stuff
ammunition.

Harriet told of the mysterious box that she had seen carried into the
woods. Later in the day this was located and dug up. It was found to
be a zinc-lined case, packed with military rifles of old pattern.

On board the "Sister Sue," in the chain locker, was found a complete
wireless equipment, together with quite a cargo of rifles and
ammunition.

"These guns were meant for _business_!" remarked the captain of the
revenue cutter, as he and another officer stood by superintending the
work of four sailors.

"Why, I thought the days of piracy had gone by," remarked Harriet.

"_Pi_--" gasped Tommy, and turned
