Larry was already breathing heavily, for he had the happy faculty, which Phil often envied, of going to sleep almost as soon as his head touched the pillow. Nor in making use of this word is reference made to some time in the past, when the two young cruisers were at home in their comfortable beds. Each of them owned a rubber pillow, which on being inflated, afforded an easy headrest; and during the day took up very little room, the air being allowed to escape in the morning.

On the first night out Larry had disdained to follow the example of his more experienced chum, who had covered his rubber pillow with a towel. Consequently Larry found that his face burned and itched all day, from the drawing effect of the bare rubber; and on this occasion Phil noted with secret satisfaction that the other was very particular to emulate his example. Experience is the best guide; and Larry would never forget the unpleasant sensation he had endured because of declining to take pattern from the actions of the "one who knew."

The last thing Phil remembered hearing ere he went to sleep was that concert from the neighboring swamp. The alligator bull had started in to bellow again, as though pleading with some rival to come around and try conclusions; and the sound was very strange, surrounded as they were by such a wilderness.

Accustomed as he was to a delightful hair mattress, of course Phil would have found it rather hard to have only a doubled blanket between the boards and himself, as Tony was doing; while he and Larry enjoyed the benefit of the cushions with which the side seats of the launch were furnished; and which, being covered with panasote, were supposed to act as life preservers should they be cast into the water. But Tony never minded it in the least. He assured them he had many times slept comfortably, perched on the limb of a tree.

Still, Phil was a light sleeper. While his chum might never awaken once during a night, Phil generally turned over every hour or so. And he had fallen into the habit, so general among old campers, of raising his head and taking an observation at such times.

Finding all well, he would lie back again, and fall into a new sleep.

He remembered doing this at least twice on this night in question. Each time it seemed to him that all was well. He could hear the various noises coming out of the swamp, and forming such a weird chorus; but they signified nothing in the way of peril. And by degrees Phil was growing accustomed to listening to the strange conglomeration.

A third time he awoke, and it struck him instantly that on this occasion he had not come out of his sleep wholly of his own accord. Something seemed to be pulling at him—it would stop for a few seconds only to go on again, and Phil noted that this tugging was wholly confined to the shoulder of his coat, which he had not discarded when he lay down, as the night air was cool.

At first a thrill passed through him. Possibly he remembered that bull 'gator with the hoarse bellow; or bethought him of certain yellow moccasin snakes Larry had noticed in the water of the stream, coming from the swamp, no doubt.

Then something touched his face, tapping him gently. Instinctively he put up his hand, and immediately felt fingers. Why, it must be Tony! Had the other thrown his arm up while sleeping, and in this way managed to arouse him; or was his action intentional?
