A second time a loud snort was heard, as though some large animal were blowing the water from his nostrils, and at the same instant Nick and Nellie caught sight of the huge snout of the bear coming through the water toward them.

He was making directly for the raft beyond all question.

"By jingo, this raft wasn't built to carry bears!" exclaimed the startled lad, who used the pole with all the strength of which he was master; but, unfortunately, the bottom of the pond was composed of slippery rocks in many places, and the blunt end of the crooked limb slid along the upper surface of one of these so quickly that Nick dropped on his side and came within a hair's breadth of rolling overboard.

But he was up again like a flash, and toiling with might and main.

Rafts as generally constructed, are not capable of much speed, and though Nick Ribsam got out all there was in the one which he had managed, it was not to be expected that he could compare with the velocity of a strong, healthy bear.

"He's coming, Nick! Oh, he will catch us sure!" exclaimed the sorely frightened Nellie, edging so far away that she, too, was in danger of going over.

"I know he is," replied the sturdy lad, working hard with the guiding pole, "and I think he can beat us. Do you stay where you are, and don't try to get any further off or you will be drowned. I'll bang him over the head if he tries to climb on here and ride with us."

Such was the purpose of the beast, beyond question; and, approaching fast, only a brief time elapsed ere his huge snout was shoved against the logs, his big paws, dripping with wet, flapped out from below the surface and both rested on the raft, which sank so low that Nellie screamed and Nick turned pale.

Determined to keep off such an undesirable passenger, the lad raised the stick in his hand and brought it down with all his strength on the head of the bear, which acted as though unaware that he was struck.

Nick repeated the blows, that would have settled the business for a less formidable animal but it was plain that brain did not consider the matter a serious one. Having secured a rest for his paws, his whole body was supported in the water, and the beast, which was no doubt very tired, simply ceased all effort, and floated with the wind.

"Why don't you knock him off?" asked Nellie, impatiently.

"Because I ain't strong enough, I suppose; he's the toughest customer I ever got hold of, or seemed to have a good chance to get hold of me."

"I've a great notion to dig out his eyes myself."

"If you try it, it will be the last bear you ever scratch; look at those paws! did you ever see such nails? didn't you hear them rattle against the logs when he struck them?"

"Suppose he tries to climb upon the raft," ventured Nellie, trying to edge still further away, "what will become of us?"

"The raft won't hold him; he'll sink it, and we'll have to get along as best we can; but, Nellie, he acts to me as though he is satisfied with being where he is, and he won't disturb us so long as we let him alone."

"But you struck him several hard blows."

"He's forgotten all about it, if he ever knew it. I guess he has had a pretty lively run to reach the pond in time to save his hide, and now that he is in the water, he will stay there a good while."

There was a likelihood that Nick was right, and that the bear wanted nothing more than a rest; and yet the possibility that he would soon try to draw his entire body upon the raft prevented the brother and sister from having any peace of mind.

When this singular tableau had lasted several minutes, it was discovered that the wind was carrying the raft, with its incubus, toward the western shore again, and Nick, afraid that if they all landed together, the bear might seize the occasion to make a supper off of them, reached the pole over the side, and began working the logs to the middle of the pond.

During this performance the brute never stirred. His head, shoulders and paws were out of the water, the principal bulk of his body being beneath, and he seemed contented to be navigated about the small lake in any fashion ............
