At that instant, Nick Ribsam felt himself suddenly lifted in air and spinning forward with great speed on the back of the vigorous hog, which plunged between his rather short legs.

The astounded lad instantly stopped laughing, and, dropping his gun and torch, grasped at something to sustain himself against the peril, the nature of which he could hardly guess.

The hog had struck him from the front, so that Nick was seated in reverse position on his back. The object which he grasped was the spiral tail of the animal, but, before he could make his grip certain, the porker swerved so suddenly to one side that Nick rolled off and bumped against a tree.

His body was not hurt to one half the extent that his feelings were, for he heard Sam Harper roaring with mirth, loud enough to be heard half a mile; and as Nick hastily clambered upon his feet, he was certain Herbert's cracked laugh was also rending the night air.

The porker, having made the round and paid his tribute to each member of the company in turn, whisked off into the woods, with a triumphant grunt, as if to say, "I guess you folks and your dog will let me alone now."

As soon as the boys found their guns, and restored two of the torches to a blaze, they looked at each other and gave way to their unrestrained mirth for several minutes before they could speak so as to be understood.

Never had a pompous expedition ended more ignobly: they had started out to attack a fierce black bear, and unexpectedly were overturned by a large-sized pig, which resented the interference with his slumber.

Some naturalists maintain that many animals possess a sense of the humorous, and it looked as though the sluggish Bowser enjoyed the joke as much as did the victims; for, when the latter made their way back to the camp fire, they saw the hound stretched out close to the warm blaze with his head between his paws and apparently asleep; but, watching him closely, he was seen to open one of his eyes, just a little ways, and, surveying them a minute, he closed it to open again a minute later.

No animal could have said more plainly:

"I've got the joke on you this time, boys, and I'm laughing so hard that I can't keep my eyes open."

"I tell you there is a good deal more in the heads of brutes than many of us think," said Nick Ribsam, after he had studied the actions of the hound; "I believe he wanted to make us believe there was some sort of game out there so as to play the fool with us."

"Do you think he foresaw the trick of the hog?" asked Herbert, who was rubbing his bruised elbows and knees.

"That would have been impossible, for we could not have foreseen it ourselves if we had arranged the joke; he simply meant to mislead us, and then we acted the fool for his amusement."

It looked very much as if Nick Ribsam was correct in his supposition, and that Bowser enjoyed even more than they the shrewd trick he had played on them.

"I suppose there are several hundred hogs wandering through the woods," said Nick, "picking up acorns and nuts that have fallen off the trees, and making a good living at it."

"Yes, lots of them have been running wild for weeks and months," added Sam, "and when their owners try to gather them in, there will be trouble, for it doesn't take hogs long to become savage."

"It didn't take that hog very long, I'm sure," observed Herbert, sitting down with care upon the ground.

"But how was it there was but one?" asked Sam.

"There wasn't need of any more than one," said Nick; "he had no trouble in doing as he pleased with us."

"But hogs go in droves, and you wouldn't be apt to find one of them by himself in the woods."

"There were others close by, for I am sure I heard them; but it is a little curious that they didn't attack us, for hogs don't know as much as dogs, and they had no reason to feel that one of their number was more than enough for us."............
