Although the cracking of rifles continued, and the teamsters, kneeling behind the fortifications, were doing their utmost to pick off some of the dusky riders, who in turn sent in their dropping shots, Captain Wadsworth gave them little heed. The position of himself and Brinton was exposed, and, had their assailants come closer, they would not have dared to maintain it; but with the combatants so widely separated, it cannot be said they were in much real danger.
The three Indians in whom our friends were so much interested just then were beyond and apart from the others. Their horses were cropping the few blades of withered grass that had survived the winter's tempests; but not one was a dozen yards from his master, all of whom were so grouped together that their movements could not be identified.
Rather curiously there was not a spy-glass among the teamsters. Such an article would have been valuable just then; but they had to depend upon their unaided vision.
The captain and Brinton, however, agreed that two of the bucks were bent over and busy with something on the ground, while the third, standing on the crest of the ridge, appeared to be awaiting the action of his companions before carrying out some plan he had in mind.
"Look!" whispered the youth; "isn't that smoke?"
The captain was silent a moment before answering—
"Yes; the Indian is like the Chinaman: he can start a fire where you and I couldn't kindle a spark. I believe they will make a bundle of water-soaked leaves crackle and burn like tinder wood. Those fellows have got some of the dried grass together and have managed to touch it off. You understand what that means, of course?"
"I cannot say that I do."
"It is a signal fire."
"Kindled for what purpose?"
