A fourth volume was given up to what occurred while the Eagles were encamped in the wilderness; where circumstances arose that called for all their knowledge of woodcraft and scout lore; but those who have read "The Boy Scouts' Mountain Camp" will surely unite in saying that Rob and his chums met the situation as became true scouts, and came out of the affair with great credit.

In the succeeding story, "The Boy Scouts for Uncle Sam," the boys found themselves involved in a succession of thrilling events. An opportunity arose whereby their services were in demand in order to save the design of a wonderful submarine craft, intended for the use of the United States Government, from being stolen by the clever agents of a foreign power. It was largely through the efforts of the scout patrol that this treacherous design was finally foiled.

A sixth volume, just preceding the present story, "The Boy Scouts at the Panama Canal," contained the history of events that befell Rob and his particular chums at a time when they were given a splendid chance to visit the great ditch which Uncle Sam was then digging down on the Isthmus. Once again they managed to bring into play the resourcefulness which, as members of the Eagle Patrol, had been developed in them; and it was principally through the agency of scoutcraft that the evil designs which certain envious nations had upon the locks of the canal were blocked.

Which short but necessary explanation once more brings us to the four chums as they tacked back and forth while trying to make the home port before dusk set in. Now that they were headed toward the mainland they made rapid progress, for the wind was certainly increasing in force right along. It came from a point that enabled them to make this the long leg, gaining quite a considerable distance. Once again they tacked, and the best they could expect to do was to hold their own in a beat toward the sandy outer shore of the bay, which helped to make the inlet all but landlocked.

"This is sure going some!" Tubby called out, as he began to get himself into readiness for another quick slide across when they should come about again; the spray was flying in their faces, more or less, and the waves that raced past seemed tipped with white.

"Look out for your heads when we swing around!" called Merritt. "That boom is heavy enough to sweep you overboard, I guess!"

"Excuse me from taking a bath right here and now!" exclaimed Tubby, who was not much of a swimmer at the best. "But see here, what does all this mean, fellers? Why, look at the water in the bottom of the boat, will you? Tell you what, she's gone and sprung a leak as sure as anything! Rob, you won't head out in the bay again, will you, with all this chance of our foundering? Gingersnaps! it keeps on getting worse and worse, I tell you! We'll sink inside of ten minutes!"

Rob, who owned the sailboat, took one look at the water that was already washing about in the bottom of the uptilted craft. He must have realized that something strange had happened to cause so staunch a boat to spring a leak, and also that the situation was serious; for no sooner had he taken in the suspicious way in which the water was rising in the cockpit, than he shouted:

"Keep her headed straight for the shore, Merritt! We've got to beach her one way or another. Tubby, help me with the halliards so we can drop the sail. You pull up the centerboard, Andy! Hurry now, everybody!"

There was a scene of activity on board the little pleasure craft just then, with three of those lively scouts springing about their duty. And as the sail came rattling down on top of the cabin, with Tubby sprawled under its folds, and as Andy fastened the heavy centerboard which he had drawn full height in the well, the boat ran up on the sandy beach of a little cove that had chanced to lie directly ahead at the time the skipper gave his hurried orders!
