Do you wonder that they immediately let out a few yelps, and scrambling to their feet, rushed headlong away, followed by the laughter and jeers of Bobolink and his hard-working assistant.

"Go it, you tigers! My! what sprinters you can be, when you only half try! Come again, when you cool off a bit! Plenty more of the same kind on tap! Don't be bashful, Teddy; let's hear from you again, and often. Whee! just listen to 'em howl, would you?"

Perhaps some of those who were with Ted Slavin in his little game were more frightened than hurt by the hot water, but they certainly did chatter as they kept on up the river bank. Little danger of them making another try to injure the boats again that night!

Of course Spider and Tom Bates had jumped up at the first outbreak, ready to help repel boarders. Their assistance was not needed; but they enjoyed the joke as much as their chums and for the next half hour all sat around, talking, and comparing notes.

But finally silence again rested over the scene; Spider and Tom condescended to crawl under their blankets again for another "cat-nap," as the former dubbed it, while Bobolink and his able assistant resumed their duties as sentries.

The night, however, was disturbed no more by any outbreak. Those would-be jokers seemed to know when they had taken hold of what Bobolink termed the "business end of a buzz-saw;" at any rate they were only conspicuous during the remainder of the night by their absence.

Of course every one of the boys on board the two motorboats was glad when the first peep of dawn came. It had seemed about "forty-eleven hours long," Spider admitted; though he also triumphantly asked Tom Betts whether the other had had occasion to jab that pin into him even once, which the second scout laughingly admitted he had not.

"See there," Spider had declared, "can't I keep awake when duty calls me? You needn't be afraid to trust a Sexton, when you need a faithful watcher."

Before the sun appeared Paul and Jack were on hand, to make sure that everything was in shape for an early start, for they hoped to get away by nine o'clock.

Others of the scouts began to drop around, and from the appearance of their eyes Paul was of the opinion that a full night's sleep had not been enjoyed by many of the members of the troop. Of course, it was the excitement of starting out on such a glorious cruise that kept them awake; for it is not given to scouts very often to enjoy such a prospect, afloat, with staunch motorboats given over into their keeping.
