Glen had left the trail, thinking to cut off a little distance by so doing; and, a few moments after Binney's leap into the air, he performed almost the same act. On his part it was entirely involuntary, and was caused by one of Nettle's fore-feet sinking into a gopher burrow that was invisible and not to be avoided.

As horse and boy rolled over together, a cry of dismay came from one side, and a wild yell of exultation from the other.


Chapter XXIII.

FIGHTING THE FINEST HORSEMEN IN THE WORLD.

It did not take many seconds for both Glen and Nettle to scramble to their feet after the tremendous header caused by the gopher-hole. Badly shaken though he was, the boy managed to regain his saddle more quickly than he had ever done before. But seconds are seconds; and, in so close a race for the most valuable of all earthly prizes, each one might be worth a minute, an hour, or even a lifetime. Glen had not more than regained his seat, before the foremost of his pursuers, who had far outstripped the other, was upon him. With an empty rifle, Glen had not the faintest hope of escape this time, though Nettle sprang bravely forward. He involuntarily cringed from the expected blow, for he had caught a fleeting glimpse of an uplifted tomahawk; but it did not come. Instead of it, he heard a crash, and turned in time to see the Indian pony and its rider pitch headlong, as he and Nettle had done a minute before. They were almost beside him; and, as he dashed away, he was conscious of wondering if they too had fallen victims to an unseen gopher-hole.

He had not noticed the figure running to meet him, nor heard one of the shots it was firing so wildly as it ran. If he had he might have realized that his salvation had not depended on a gopher-hole, but on one of those random shots from Binney Gibbs's rifle. By the merest chance, for it was fired without aim and almost without direction, it had pierced the brain of the Indian pony, and decided that race in favor of Glen.

When, to Glen's great surprise, the two boys met, he sprang from Nettle's back and insisted that Binney should take his place, which the other resolutely refused to do. So Glen simply tossed the bridle rein into Binney's hand, and started off on a full run. In a moment Nettle, with Binney on her back, had overtaken him, and the generous dispute might have been resumed had not a party of mounted men from the wagon-train just then dashed up and surrounded the boys. They were headed by "Billy" Brackett, who cried out,

"Well, you're a pretty pair of babes in the woods, aren't you? And you've been having lots of fun at the expense of our anxiety! But jump up behind me, Glen, quick, for I believe every wild Injun of the Plains is coming down that hill after us at this moment."

Just before the first shots were heard, some anxiety had been felt in the train concerning the boys who had lagged behind, and "Billy" Brackett had already asked if he had not better look them up. Then, as the sound of firing came over the ridge, and the boys were known to have got into some sort of trouble, he rode back at full speed, followed by a dozen of the men. All were equally ready to go, but the rest were ordered to remain behind for the protection of the train. Then the wagons were quickly drawn up in double line, and the spare stock was driven in between them.
