"The Injun's back. You better be goin'." The girl slipped a small revolver from her pocket and pressed it into Alice's hand. "There's a pocket for it in the bloomers. Cinnabar Joe give it to me a long time ago. Take care of yourself an' don't be afraid to use it if you have to. An' mind you let me hear jest the minute you git anywheres. I'll be a-dyin' to know what become of you."

Alice promised and as she passed through the door, leaned swiftly and kissed the girl squarely upon the lips.

"Good-bye," she whispered. "I won't forget you," and the next moment she stepped out to join the waiting half-breed, who with a glance of approval at her costume, took the bag from her hand and proceeded to secure it behind the cantle. The girl mounted without assistance, and snubbing the lead-rope of the pack-horse about the horn of his saddle, the half-breed led off into the night.

Hour after hour they rode in silence, following a trail that wound in easy curves about the bases of hillocks and small buttes, and dipped and slanted down the precipitous sides of deep coulees where the horses' feet splashed loudly in the shallow waters of fords. As the moon dipped lower and lower, they rode past the darkened buildings of ranches nestled beside the creeks, and once they passed a band of sheep camped near the trail. The moonlight showed a sea of grey, woolly backs, and on a near-by knoll stood a white-covered camp-wagon, with a tiny lantern burning at the end of the tongue. A pair of hobbled horses left off snipping grass beside the trail and gazed with mild interest as the two passed, and beneath the wagon a dog barked. At length, just as the moon sank from sight behind the long spur of Tiger Butte, the trail slanted into a wide coulee from the bottom of which sounded the tinkle of running water.

"Dis Snake Creek," remarked the Indian; "better you git off now an' stretch you leg. Me, A'm mak' de blanket on de groun' an' you ketch-um little sleep. Mebbe-so dem com' queek—mebbe-so long tam'."

Even as he talked the man spread a pair of new blankets beside the trail and walking a short distance away seated himself upon a rock and lighted a cigarette.

With muscles aching from the unaccustomed strain of hours in the saddle, Alice threw herself upon the blankets and pillowed her head on the slicker that the half-breed had folded for the purpose. Almost immediately she fell asleep only to awake a few moments later with every bone in her body registering an aching protest at the unbearable hardness of her bed. In vain she turned from one side to the other, in an effort to attain a comfortable position. With nerves shrieking at each new attitude, all thought of sleep vanished and the girl's brain raced madly over the events of the past few hours. Yesterday she had sat upon the observation platform of the overland train and complained to Endicott of the humdrum conventionality of her existence! Only yesterday—and it seemed weeks ago. The dizzy whirl of events that had snatched her from the beaten path and deposited her somewhere out upon the rim of the world had come upon her so suddenly and with such stupendous import that it beggared any attempt to forecast its outcome. With a shudder she recalled the moment upon the verge of the bench when in a flash she had realized the true character of Purdy and her own utter helplessness. With a great surge of gratitude—and—was it only gratitude—this admiration and pride in the achievement of the man who had rushed to her rescue? Alone there in the darkness the girl flushed to the roots of her hair as she realized that it was for this man she had unhesitatingly and unquestioningly ridden far into the night in company with an unknown Indian. Realized, also, that above the pain of her tortured muscles, above the uncertainty of her own position, was the anxiety and worry as to the fate of Endicott. Where was he? Had Tex lied when he told her there would be no lynching? Even if he desired could he prevent the cowboys from wreaking their vengeance upon the man who had killed one of their number? She recalled with a shudder the cold cynicism of the smile that habitually curled the lips of the Texan. A man who could smile like that could lie—could do anything to gain an end. And yet—she realized with a puzzled frown that in her heart was no fear of him—no terror such as struck into her very soul at the sudden unmasking of Purdy. "It's his eyes," she murmured; "beneath his cynical exterior lies a man of finer fibre."

Some distance away a match flared in the darkness and went out, and dimly by the little light of the stars Alice made out the form of the half-breed seated upon his rock beside the trail. Motionless as the rock itself the man sat humped over with his arms entwining his knees. A sombre figure, and one that fitted intrinsically into the scene—the dark shapes of the three horses that snipped grass beside the trail, the soft murmur of the waters of the creek as they purled over the stones, the black wall of the coulee, with the mountains rising beyond—all bespoke the wild that since childhood she had pictured, but never before had seen. Under any other circumstances the setting would have appealed, would have thrilled her to the soul. But now—over and over through her brain repeated the question: Where is he?

A horse nickered softly and raising his head, sniffed the night air. The Indian stepped from his rock and stood alert with his eyes on the reach of the back-trail. And then softly, almost inaudibly to the ears of the girl came the sound of horses' hoofs pounding the trail in monotonous rhythm.

Leaping to her feet she rushed forward in time to see Bat catch up the reins of the three horses and slip noiselessly into the shelter of a bunch of scrub willows. In a moment she was at his side and the Indian thrust the reins into her hand.
