On two occasions, though, the lad was in deadly peril; once when, growing impatient, the Apachés, in hunting fashion, had made a cast or two to recover the trail they had lost, galloping on some miles, and taking it up again pretty close to where Bart had been resting again somewhat too long for safety, though far from being long enough to recoup the losses he had sustained.

The next time was under similar circumstances, the Apachés picking up the sign of his having passed over the plain close beside a patch of rising ground, where he had been tempted into shooting a prong-horn antelope, lighting a fire, and making a hearty meal, of which he stood sadly in need.

The meal ended, a feeling of drowsiness came over the feaster, and this time Bart did not yield to it, for he felt that he must place many more miles behind him before it grew dark; so, rolling up the horse-hair lariat by which Black Boy had been tethered, once again he tightened the girths, and was just giving his final look round before mounting, congratulating himself with the thought that he had enough good roasted venison to last him for a couple more days, when his horse pricked his ears and uttered an impatient snort.

Just at the same moment there was the heavy thud, thud, thud, of horses’ hoofs, and, without stopping to look, Bart swung himself up on his horse’s back and urged him forward with hand, heel, and voice.

The plain before him was as level as a meadow, not a stone being in sight for miles, so that unless the cob should put his foot in some burrow, there was nothing to hinder his racing off and escaping by sheer speed.

There was this advantage too: Black Boy had been having a good rest and feed, while the pursuers had doubtless been making a long effort to overtake him.

The Apachés set up a furious yell as they caught sight of their prey, and urged on their horses, drawing so near before Bart could get anything like a good speed on, that they were not more than fifty yards behind, and thundering along as fast as they could urge their ponies.

This went on for half a mile, Bart feeling as if his heart was in his mouth, and that the chances of escape were all over; but somehow, in spite of the terrible peril he was in, he thought more about the Doctor and the fate of his expedition than he did of his own. For it seemed so terrible that his old friend and guardian—one who had behaved to him almost as a father should be waiting there day after day expecting help in vain, and perhaps thinking that his messenger had failed to do his duty.

“No, he won’t, nor Joses neither, think that of me,” muttered Bart. “I wish the Beaver were here to cheer one up a bit, as he did that other time when these bloodthirsty demons were after us.”

“How their ponies can go!” he panted, as he turned his head to gaze back at the fierce savages, who tore along with feathers and long hair streaming behind them, as wild and rugged as the manes and tails of their ponies.
