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?"
