Having ordered the ambulance up the gorge, he himself spurred away to gather in all stragglers within reach, so as to reinforce the little garrison at the caves in the event of attack from the Apaches. To his practised eye no vestige of doubt remained as to the character and purpose of the signal-smokes. Not a moment was to be lost. Within that very hour, perhaps, unseen Indians would come skulking, spying, "snaking" upon their refuge, would be able, infallibly, to determine the number and character of its occupants, and, if their own force were considerable and that of the garrison weak, God alone could help those innocent women. When last noted the westward signal was puffing slowly up into the cloudless sky from a point in the range perhaps six miles below Patterson's station in the rocks. The three wearied troopers dragging slowly back from the chase could be seen coming up the valley probably four miles away, some distance, therefore, ahead of the supposed position of the foe. Wing well knew with what goat-like agility the mountain Indians could speed along from rock to rock and still keep under cover, and every man who had served a month in Arizona could have predicted that if Indians in any force were within a day's march of those three stragglers ambush and death would be their fate, perhaps even when within view of their longed-for goal. That they had not seen the sign, that they were ignorant of the possible presence of Apaches in the range, was manifest simply because they rode close along under the foot-hills, often over the bowlder-strown outskirt of the _falda_, and, though still far from them, such was Wing's anxiety for their safety that he rode furiously along, signalling with his left hand as though to say "Keep out! Keep to your right! Don't go so close to the rocks!"
