Before they had ridden half an hour the sun went down suddenly behind serrated steeps, and almost immediately night hastened in with his obscurities. Texas Smith, riding hundreds of yards in the rear and concealing himself behind the turning points of the cañon, was obliged to diminish his distance in order to keep them under his guard. Clara had repeatedly expressed her doubts as to the road, and Coronado had as often asserted that they would soon see the train. At last the ravine became a gully, winding up a breast of shadowy mountain cumbered with loose rocks, and impassable to horses.
"We are lost," confessed Coronado, and then proceeded to console her. The train could not be far off; their friends would undoubtedly seek them; at all events, would not go on without them. They must bivouac there as well as might be, and in the morning rejoin the caravan.
He had been forethoughted enough to bring two blankets on his saddle, and he now spread them out for her, insisting that she should try to sleep. Clara cried frankly and heartily, and begged him to lead her back through the cañon. No; it could not be traversed by night, he asserted; they would certainly break their necks among the bowlders. At last the girl suffered herself to be wrapped in the blankets, and made an endeavor to forget her wretchedness and vexation in slumber.
Meantime, a few hundred yards down the ravine, a tragedy was on the verge of action. Thurstane, missing Coronado and Clara, and learning what direction they had taken, started with two of his soldiers to find them, and was now picking his way on foot along the cañon. Behind a detached rock at the base of one of the sandstone walls Texas Smith lay in ambush, aiming his rifle first at one and then at another of this stumbling trio, and cursing the starlight because it was so dim that he could not positively distinguish which was the officer.
CHAPTER IX.
For the second time within a week, Texas Smith found himself upon the brink of opportunity, without being able (as he had phrased it to Coronado) to do what was right.
He levelled at Thurstane, and then it did not seem to be Thurstane; he had a dead sure sight at Kelly, and then perceived that that was an error; he drew a bead on Shubert, and still he hesitated. He could distinguish the Lieutenant's voice, but he could not fix upon the figure which uttered it.
It was exasperating. Never had an assassin been better ambuscaded. He was kneeling behind a little ridge of sandstone; about a foot below its edge was an orifice made by the rains and winds of bygone centuries; through this, as through an embrasure, he had thrust his rifle. Not a chance of being hit by a return shot, while after the enemy's fire had been drawn he could fly down the ravine, probably without discovery and certainly without recognition. His horse was tethered below, behind another rock; and he felt positive that these men had not come upon it. He could mount, drive their beasts before him into the plain, and then return to camp. No need of explaining his absence; he was the head hunter of the expedition; it was his business to wander.
All this was so easy to do, if he could only take the first step. But he dared not fire lest he should merely kill a soldier, and so make an uproar and rouse suspicions without the slightest profit. It was not probable that Coronado would pay him for shooting the wrong man, and setting on foot a dangerous investigation. So the desperado continued to peer through the dim night, cursing his stars and everybody's stars for not shining better, and seeing his opportunity slip rapidly away. After Thurstane and the others had passed, after the chance of murder had stalked by him like a ghost and vanished, he left his ambush, glided down the ravine to his horse, waked him up with a vindictive kick, leaped into the saddle, and hastened to camp. To inquiries about the lost couple he replied in his sullen, brief way that he had not seen them; and when urged to go to their rescue, he of course set off in the wrong direction and travelled but a short distance.
