strength left to make an effort to get out of the desert。 But that same inscrutable something which had ordered his strange involuntary promise to Warren held him beside his fallen comrade。 He watched the white sun turn to gold； and then to red and sink behind mountains in the west。 Twilight stole into the arroyo。 It lingered； slowly turning to gloom。 The vault of blue black lightened to the blinking of stars。 Then fell the serene； silent； luminous desert night。
Cameron kept his vigil。 As the long hours wore on he felt creep over him the comforting sense that he need not forever fight sleep。 A wan glow flared behind the dark； uneven horizon； and a melancholy misshapen moon rose to make the white night one of shadows。 Absolute silence claimed the desert。 It was mute。 Then that inscrutable something breathed to him； telling him when he was along。 He need not have looked at the dark； still face beside him。
Another face haunted Cameron'sa woman's face。 It was there in the white moonlit shadows； it drifted in the darkness beyond； it softened； changed to that of a young girl； sweet； with the same dark； haunting eyes of her mother。 Cameron prayed to that nameless thing within him； the spirit of something deep and mystical as life。 He prayed to that nameless thing outside； of which the rocks and the sand； the spiked cactus and the ragged lava； the endless waste； with its vast star…fired mantle； were but atoms。 He prayed for mercy to a womanfor happiness to her child。 Both mother and daughter were close to him then。 Time and distance were annihilated。 He had faithhe saw into the future。 The fateful threads of the past； so inextricably woven with his error； wound out their tragic length here in this forlorn desert。
CAMERON then took a little tin box from his pocket； and； opening it； removed a folded certificate。 He had kept a pen； and now he wrote something upon the paper； and in lieu of ink he wrote with blood。 The moon afforded him enough light to see； and； having replaced the paper； he laid the little box upon a shelf of rock。 It would remain there unaffected by dust； moisture； heat； time。 How long had those painted images been there clear and sharp on the dry stone walls？ There were no trails in that desert； and always there were incalculable changes。 Cameron saw this mutable mood of naturethe sands would fly and seep and carve and bury； the floods would dig and cut； the ledges would weather in the heat and rain； the avalanches would slide； the cactus seeds would roll in the wind to catch in a niche and split the soil with thirsty roots。 Years would pass。 Cameron seemed to see them； too； and likewise destiny leading a child down into this forlorn waste； where she would find love and fortune； and the grave of her father。
Cameron covered the dark； still face of his comrade from the light of the waning moon。
That action was the severing of his hold on realities。 They fell away from him in final separation。 Vaguely； dreamily he seemed to behold his soul。 Night merged into gray day； and night came again； weird and dark。 Then up out of the vast void of the desert； from the silence and illimitableness； trooped his phantoms of peace。 Majestically they formed around him； marshalling and mustering in ceremonious state； and moved to lay upon him their passionless serenity。
Chapter I
Old Friends
Richard Gale reflected that his sojourn in the West had been what his disgusted father had predictedidling here and there； with no objective point or purpose。
It was reflection such as this； only more serious and perhaps somewhat desperate； that had brought Gale down to the border。 For some time the newspapers had been printing news of Mexican revolution； guerrilla warfare； United States cavalry patrolling the international line； American cowboys fighting with the rebels； and wild stories of bold raiders and bandits。 But as opportunity； and adventure； too； had apparently given him a wide berth in Montana； Wyoming； Colorado； he had struck southwest for the Arizona border； where he hoped to see some stirring life。 He did not care very much what happened。 Months of futile wandering in the hope of finding a place where he fitted had inclined Richard to his father's opinion。
It was after dark one evening in early October when Richard arrived in Casita。 He was surprised to find that it was evidently a town of importance。 There was a jostling； jabbering； sombreroed crowd of Mexicans around the railroad station。 He felt as if he were in a foreign country。 After a while he saw several men of his nationality； one of whom he engaged to carry his luggage to a hotel。 They walked up a wide； well…lighted street lined with buildings in which were bright windows。 Of the many people encountered by Gale most were Mexicans。 His guide explained that the smaller half of Casita lay in Arizona； the other half in Mexico； and of several thousand inhabitants the majority belonged on the southern side of the street； which was the boundary line。 He also said that rebels had entered the town that day； causing a good deal of excitement。
Gale was almost at the end of his financial resources； which fact occasioned him to turn away from a pretentious hotel and to ask his guide for a cheaper lodging…house。 When this was found； a sight of the loungers in the office； and also a desire for comfort； persuaded Gale to change his traveling…clothes for rough outing garb and boots。
〃Well； I'm almost broke；〃 he soliloquized； thoughtfully。 〃The governor said I wouldn't make any money。 He's rightso far。 And he said I'd be coming home beaten。 There he's wrong。 I've got a hunch that something 'll happen to me in this Greaser town。〃
He went out into a wide； whitewashed； high…ceiled corridor； and from that into an immense room which； but for pool tables； bar； benches； would have been like a courtyard。 The floor was cobblestoned； the walls were of adobe； and the large windows opened like doors。 A blue cloud of smoke filled the place。 Gale heard the click of pool balls and the clink of glasses along the crowded bar。 Bare…legged； sandal…footed Mexicans in white rubbed shoulders with Mexicans mantled in black and red。 There were others in tight…fitting blue uniforms with gold fringe or tassels at the shoulders。 These men wore belts with heavy； bone…handled guns； and evidently were the rurales； or native policemen。 There were black…bearded； coarse…visaged Americans； some gambling round the little tables； others drinking。 The pool tables were the center of a noisy crowd of younger men； several of whom were unsteady on their feet。 There were khaki…clad cavalrymen strutting in and out。
At one end of the room； somewhat apart from the general meelee； was a group of six men round a little table； four of whom were seated； the other two standing。 These last two drew a second glance from Gale。 The sharp…featured； bronzed faces and piercing eyes； the tall； slender； loosely jointed bodies； the quiet； easy； reckless air that seemed to be a part of the menthese things would plainly have stamped them as cowboys without the buckled sombreros； the colored scarfs； the high…topped； high…heeled boots with great silver…roweled spurs。 Gale did not fail to note； also； that these cowboys wore guns； and this fact was rather a shock to his idea of the modern West。 It caused him to give some credence to the rumors of fighting along the border； and he felt a thrill。
He satisfied his hunger in a restaurant adjoining； and as he stepped back into the saloon a man wearing a military cape jostled him。 Apologies from both were instant。 Gale was moving on when the other stopped short as if startled； and； leaning forward； exclaimed：
〃Dick Gale？〃
〃You've got me；〃 replied Gale； in surprise。 〃But I don't know you。〃
He could not see the stranger's face； because it was wholly shaded by a wide…brimmed hat pulled well down。
〃By Jove！ It's Dick！ If this isn't great！ Don't you know me？〃
〃I've heard your voice somewhere；〃 replied Gale。 〃Maybe I'll recognize you if you come out from under that bonnet。〃
For answer the man； suddenly manifesting thought of himself； hurriedly drew Gale into the restaurant； where he thrust back his hat to disclose a handsome； sunburned face。
〃George @Thorne！ So help me〃
〃'S…s…ssh。 You needn't yell；〃 interrupted the other； as he met Gale's outstretched hand。 There was a close； hard； straining grip。 〃I must not be recognized here。
There are reasons。 I'll explain in a minute。 Say； but it's fine to see you！ Five years； Dick； five years since I saw you run down University Field and spread…eagle the whole Wisconsin football team。〃
〃Don't recollect that；〃 replied Dick； laughing。 〃George； I'll bet you I'm gladder to see you than you are to see me。 It seems to long。 You went into the army； didn't you？〃
〃I did。 I'm here now with the Ninth Cavalry。 Butnever mind me。 What're you doing way down here？ Say； I just noticed your togs。 Dick； you can't be going in for mining or ranching； not in this God…forsaken desert？〃
〃On the square； George； I don't know any more why I'm here thanthan you know。〃
〃Well； that beats me！〃 ejaculated Thorne； sitting back in his chair； amaze and concern in his e
