It might have seemed possible to some to flank the danger by turning far to the right or left, but that would have involved a long detour and delay in arriving home. At the same time, if any warriors were on the watch, they could easily checkmate him by accommodating their movements to his, and continually heading him off, whichever direction he took. He had considered all these contingencies, and felt no hesitation in pressing straight forward, despite the apparent peril involved in doing so.
Suddenly Jack pricked his ears and raised his head, emitting at the same time a slight whiff through his nostrils.
No words could have said more plainly: "Beware, master! I have discovered something."
The rider's natural supposition was that the danger, whatever it might be, was on the crest of the ridge he was approaching; but, when he shaded his eyes and peered forward, he was unable to detect anything at all. Enough light remained in the sky for him to use his excellent eyes to the best advantage, but nothing rewarded the scrutiny.
Jack continued advancing, though his gait was now a slow walk, as if he expected his master to halt altogether; but the latter acted like the skilful railway engineer, who, seeing the danger signal ahead, continues creeping slowly toward it, ready to check his train on the instant it becomes necessary to do so. He allowed the pony to step tardily forward, while he strove to locate the point whence peril threatened.
"What the mischief do you see, Jack?" he asked, in a half-impatient tone; "if I didn't know you never joked, I would believe you were trying some trick on me to get me to camp for the night."
Once the horseman fancied he caught the faint outlines of a thin column of smoke climbing into the sky from the crest of the ridge, but closer study convinced him that he was wrong. If such a signal were kindled, it must be clear enough to be recognized from the farther elevation, which was more distant than the horseman.
"I shall observe the vapor as soon as they," he thought, "for my eyes are as sharp—helloa! that beats the mischief!"
At last Warren Starr learned what it was that had alarmed his pony.
