This emboldened Bart, who went steadily on, reducing the distance between him and the herd; and it was a curious sensation that which came upon the lad as he walked nearer and nearer to the furious-looking beasts.

Then his heart gave a tremendous throb, and seemed to stand still, for, without warning, and moved as if by one impulse, the bison charged again, but this time not half the distance; and as Bart did not run from them, they evidently thought that some one ought to flee, so they galloped back.

Bart was encouraged now, and began to feel plenty of contempt for the monsters, and walking more swiftly, the beasts charged twice more, the last time only about the length of their bodies, and this was when Bart was so near that he could almost feel their hot moist breath.

This was the last charge, for as they turned the leading bull evidently communicated his opinion that the young visitor was a stupid kind of being, whom it was impossible to frighten, and the whole herd set off at a lumbering gallop, but as they did so two rifle-shots rang out, and two bulls hung back a little, evidently wounded.

Joses led up Bart’s horse as the lad reloaded, and put the rein in his hand.

“There, off after your own bull, my lad. It was bravely done. I’m off after mine.”

Then they separated, and after a short, gallop Bart reached his quarry, and better able now to manage his task, he rode up on its right side, and a well-placed bullet tumbled the monstrous creature over on the plain dead.

Joses had to give two shots before he disabled his own bison, but the run was very short; and when Bart and he looked round they were not above a couple of hundred yards apart, and the Beaver and a couple of Indians were cantering towards them.

That evening their messengers returned with a couple of the white men and two waggons, which were taken in triumph next morning to the camp, heavily laden with bison-meat; and as they came near the mountain, Bart drew rein to stay and watch the curious sight before him, for, evidently in pursuance of the Doctor’s idea to make the top of the mountain the stronghold of the silver adventurers, there was quite a crowd of the people toiling up the path up the mountain, all laden with packages and the various stores that had been brought for the adventure.

“Been pretty busy since we’ve been gone, Master Bart,” said Joses, grimly. “Won’t they come scuffling down again when they know there’s meat ready for sharing out.”
