Morning told Cameron that they had turned back miles into the desert； and it was desert new to him。 The red sun； the increasing heat； and especially the variety and large size of the cactus plants warned Cameron that he had descended to a lower level。 Mountain peaks loomed on all sides； some hear； others distant； and one； a blue spur； splitting the glaring sky far to the north； Cameron thought he recognized as a landmark。 The ascent toward it was heartbreaking； not in steepness； but in its league…and league…long monotonous rise。 Cameron knew there was only one hopeto make the water hold out and never stop to rest。 Warren began to weaken。 Often he had to halt。 The burning white day passed； and likewise the night； with its white stars shining so pitilessly cold and bright。
Cameron measured the water in his canteen by its weight。 Evaporation by heat consumed as much as he drank。 During one of the rests； when he had wetted his parched mouth and throat； he found opportunity to pour a little water from his canteen into Warren's。
At first Cameron had curbed his restless activity to accommodate the pace of his elder comrade。 but now he felt that he was losing something of his instinctive and passionate zeal to get out of the desert。 The thought of water came to occupy his mind。 He began to imagine that his last little store of water did not appreciably diminish。 He knew he was not quite right in his mind regarding water； nevertheless； he felt this to be more of fact than fancy； and he began to ponder。
When next they rested he pretended to be in a kind of stupor； but he covertly watched Warren。 The man appeared far gone； yet he had cunning。 He cautiously took up Cameron's canteen and poured water into it from his own。
This troubled Cameron。 The old irritation at not being able to thwart Warren returned to him。 Cameron reflected； and concluded that he had been unwise not to expect this very thing。 Then； as his comrade dropped into weary rest； he lifted both canteens。 If there were any water in Warren's； it was only very little。 Both men had been enduring the terrible desert thirst； concealing it； each giving his water to the other； and the sacrifice had been useless。
Instead of ministering to the parched throats of one or both； the water had evaporated。 When Cameron made sure of this； he took one more drink； the last； and poured the little water left into Warren's canteen。 He threw his own away。
Soon afterward Warren discovered the loss。
〃Where's your canteen？〃 he asked。
〃The heat was getting my water； so I drank what was left。〃
〃My son！〃 said Warren。
The day opened for them in a red and green hell of rock and cactus。 Like a flame the sun scorched and peeled their faces。 Warren went blind from the glare； and Cameron had to lead him。 At last Warren plunged down； exhausted； in the shade of a ledge。
Cameron rested and waited； hopeless； with hot； weary eyes gazing down from the height where he sat。 the ledge was the top step of a ragged gigantic stairway。 Below stretched a sad； austere； and lonely valley。 A dim； wide streak； lighter than the bordering gray； wound down the valley floor。 Once a river had flowed there； leaving only a forlorn trace down the winding floor of this forlorn valley。
Movement on the part of Warren attracted Cameron's attention。 Evidently the old prospector had recovered his sight and some of his strength。 for he had arisen； and now began to walk along the arroyo bed with his forked peach branch held before him。 He had clung to the precious bit of wood。 Cameron considered the prospect for water hopeless； because he saw that the arroyo had once been a canyon； and had been filled with sands by desert winds。 Warren； however； stopped in a deep pit； and； cutting his canteen in half； began to use one side of it as a scoop。 He scooped out a wide hollow； so wide that Cameron was certain he had gone crazy。 Cameron gently urged him to stop； and then forcibly tried to make him。 But these efforts were futile。 Warren worked with slow； ceaseless； methodical movement。 He toiled for what seemed hours。 Cameron； seeing the darkening； dampening sand； realized a wonderful possibility of water； and he plunged into the pit with the other half of the canteen。 Then both men toiled； round and round the wide hole； down deeper and deeper。 The sand grew moist； then wet。 At the bottom of the deep pit the sand coarsened； gave place to gravel。 Finally water welled in； a stronger volume than Cameron ever remembered finding on the desert。 It would soon fill the hole and run over。 He marveled at the circumstance。 The time was near the end of the dry season。 Perhaps an underground stream flowed from the range behind down to the valley floor； and at this point came near to the surface。 Cameron had heard of such desert miracles。
The finding of water revived Cameron's flagging hopes。 But they were short…lived。 Warren had spend himself utterly。
〃I'm done。 Don't linger；〃 he whispered。 〃My son； gogo！〃
Then he fell。 Cameron dragged him out of the sand pit to a sheltered place under the ledge。 While sitting beside the failing man Cameron discovered painted images on the wall。 Often in the desert he had found these evidences of a prehistoric people。 Then； from long habit； he picked up a piece of rock and examined it。 Its weight made him closely scrutinize it。 The color was a peculiar black。 He scraped through the black rust to find a piece of gold。 Around him lay scattered heaps of black pebbles and bits of black； weathered rock and pieces of broken ledge； and they showed gold。
〃Warren！ Look！ See it！ Feel it！ Gold！〃
But Warren had never cared； and now he was too blind to see。
〃Gogo！〃 he whispered。
Cameron gazed down the gray reaches of the forlorn valley； and something within him that was neither intelligence nor emotionsomething inscrutably strangeimpelled him to promise。
The Cameron built up stone monuments to mark his gold strike。 That done； he tarried beside the unconscious Warren。 Moments passedgrew into hours。 Cameron still had 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。

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 t
