Bob noted this fact when he again looked up toward the darkening heavens.

“We will have to leave the rest of the traps until another day,” he said to himself, uneasily. “I promised mother that I would not take any more chances than necessary, and she did not seem any too well satisfied about our crossing to-day, as it was. But, how queer Sandy does not come! Perhaps I’d better start back after him.”

Once this idea had taken root in his mind, Bob could not remain at ease. He arose to his feet, took the mink in one hand, with his rifle clutched in the other, and started off.

Hardly had he taken ten steps when he heard a call. It was certainly his own name, and coupled with a word that sent a thrill through him.

“Bob! oh! Bob! Help!”

Instantly the boy dropped the mink, utterly unmindful of the value of the fine pelt. He started off at a swift pace, heading in the direction whence the shout came.

If Sandy was in danger, then it must be some of those hateful French trappers again. Bob could remember how they had first met them, and there were three at that time. A fine deer had fallen before the gun of one of the brothers, and, upon rushing forward to bleed the prize, they found themselves confronted by a trio of burly men whose appearance told the lads that they were French trappers, even before they proved this fact by their speech.

These fellows had claimed that they shot the deer, and there was trouble in prospect that might have ended seriously, but for the fortunate coming of Kenton and two companions, who proved the right of the boys to the spoils, and sent the Frenchmen away, with a warning not to look back or they would rue it.

Quickly Bob covered the ground. All the while he had his gun ready for use in case of necessity. Now he could see Sandy, and, when he discovered the other on hands and knees, great was his wonder, until he heard him cry out:

“Take care, Bob, there’s a big panther in the brush close by, and bent on jumping on you! My foot’s fast in the trap, and I can’t get free. Go slow, and be ready to shoot, for he’s savage with hunger, and as fierce as they make them. Look out! there he comes now!”
