leading him therean eagle eye； or hate； or instinct？ Why did he go on when there could be no turning back for him on that trail？ Ladd was slow； heavy； staggering on the trail； but he was relentless。 Only death could stop the ranger now。 Surely Rojas must have known that when he chose the trail。 From time to time Gale caught glimpses of Yaqui's dark figure stealing along the higher rim of the crater。 He was making for a point above the bandit。
Momentsendless moments dragged by。 The lowering sun colored only the upper half of the crater walls。 Far down the depths were murky blue。 Again Gale felt the insupportable silence。 The red haze became a transparent veil before his eyes。 Sinister； evil； brooding； waiting； seemed that yawning abyss。 Ladd staggered along the trail； at times he crawled。 The Yaqui gained； he might have had wings； he leaped from jagged crust to jagged crust； his sure…footedness was a wonderful thing。
But for Gale the marvel of that endless period of watching was the purpose of the bandit Rojas。 He had now no weapon。 Gale's glass made this fact plain。 There was death behind him； death below him； death before him； and though he could not have known it； death above him。 He never falterednever made a misstep upon the narrow； flinty trail。 When he reached the lower end of the level ledge Gale's poignant doubt became a certainty。 Rojas had seen Mercedes。 It was incredible； yet Gale believed it。 Then； his heart clamped as in an icy vise； Gale threw forward the Remington； and sinking on one knee； began to shoot。 He emptied the magazine。 Puffs of dust near Rojas did not even make him turn。
As Gale began to reload he was horror…stricken by a low cry from Thorne。 The cavalryman had recovered consciousness。 He was half raised； pointing with shaking hand at the opposite ledge。 His distended eyes were riveted upon Rojas。 He was trying to utter speech that would not come。
Gale wheeled； rigid now； steeling himself to one last forlorn hope that Mercedes could defend herself。 She had a gun。 He doubted not at all that she would use it。 But； remembering her terror of this savage； he feared for her。
Rojas reached the level of the ledge。 He halted。 He crouched。 It was the act of a panther。 Manifestly he saw Mercedes within the cave。 Then faint shots patted the air； broke in quick echo。 Rojas went down as if struck a heavy blow。 He was hit。 But even as Gale yelled in sheer madness the bandit leaped erect。 He seemed too quick； too supple to be badly wounded。 A slight； dark figure flashed out of the cave。 Mercedes！ She backed against the wall。 Gale saw a puff of whiteheard a report。 But the bandit lunged at her。 Mercedes ran； not to try to pass him； but straight for the precipice。 Her intention was plain。 But Rojas oustripped her； even as she reached the verge。 Then a piercing scream pealed across the cratera scream of despair。
Gale closed his eyes。 He could not bear to see more。
Thorne echoed Mercedes's scream。 Gale looked round just in time to leap and catch the cavalryman as he staggered； apparently for the steep slope。 And then； as Gale dragged him back； both fell。 Gale saved his friend； but he plunged into a choya。 He drew his hands away full of the great glistening cones of thorns。
〃For God's sake； Gale； shoot！ Shoot！ Kill her！ Kill her！。。。Can't yousee…Rojas〃
Thorne fainted。
Gale； stunned for the instant； stood with uplifted hands； and gazed from Thorne across the crater。 Rojas had not killed Mercedes。 He was overpowering her。 His actions seemed slow； wearing； purposeful。 Hers were violent。 Like a trapped she…wolf； Mercedes was fighting。 She tore； struggled； flung herself。
Rojas's intention was terribly plain。
In agony now； both mental and physical； cold and sick and weak； Gale gripped his rifle and aimed at the struggling forms on the ledge。 He pulled the trigger。 The bullet struck up a cloud of red dust close to the struggling couple。 Again Gale fired； hoping to hit Rojas； praying to kill Mercedes。 The bullet struck high。 A thirdfourthfifth time the Remington spokein vain！ The rifle fell from Gale's racked hands。
How horribly plain that fiend's intention！ Gale tried to close his eyes； but could not。 He prayed wildly for a sudden blindness to faint as Thorne had fainted。 But he was transfixed to the spot with eyes that pierced the red light。
Mercedes was growing weaker； seemed about to collapse。
〃Oh； Jim Lash； are you dead？〃 cried Gale。 〃Oh； Laddy！。。。Oh； Yaqui！
Suddenly a dark form literally fell down the wall behind the ledge where Rojas fought the girl。 It sank in a heap； then bounded erect。
〃Yaqui！〃 screamed Gale； and he waved his bleeding hands till the blood bespattered his face。 Then he choked。 Utterance became impossible。
The Indian bent over Rojas and flung him against the wall。 Mercedes； sinking back； lay still。 When Rojas got up the Indian stood between him and escape from the ledge。 Rojas backed the other way along the narrowing shelf of lava。 His manner was abject； stupefied。 Slowly he stepped backward。
It was then that Gale caught the white gleam of a knife in Yaqui's hand。 Rojas turned and ran。 He rounded a corner of wall where the footing was precarious。 Yaqui followed slowly。 His figure was dark and menacing。 But he was not in a hurry。 When he passed off the ledge Rojas was edging farther and farther along the wall。 He was clinging now to the lava； creeping inch by inch。 Perhaps he had thought to work around the buttress or climb over it。 Evidently he went as far as possible； and there he clung； an unscalable wall above； the abyss beneath。
The approach of the Yaqui was like a slow dark shadow of gloom。 If it seemed so to the stricken Gale what must it have been to Rojas？ He appeared to sink against the wall。 The Yaqui stole closer and closer。 He was the savage now； and for him the moment must have been glorified。 Gale saw him gaze up at the great circling walls of the crater； then down into the depths。 Perhaps the red haze hanging above him； or the purple haze below； or the deep caverns in the lava； held for Yaqui spirits of the desert； his gods to whom he called。 Perhaps he invoked shadows of his loved ones and his race； calling them in this moment of vengeance。
Gale heardor imagined he heardthat wild； strange Yaqui cry。
Then the Indian stepped close to Rojas； and bent low； keeping out of reach。 How slow were his motions！ Would Yaqui nevernever end it？。。。A wail drifted across the crater to Gale's ears。
Rojas fell backward and plunged sheer。 The bank of white choyas caught him； held him upon their steel spikes。 How long did the dazed Gale sit there watching Rojas wrestling and writhing in convulsive frenzy？ The bandit now seemed mad to win the delayed death。
When he broke free he was a white patched object no longer human； a ball of choya burrs； and he slipped off the bank to shoot down and down into the purple depths of the crater。

Changes At Forlorn River
The first of March saw the federal occupation of the garrison at Casita。 After a short； decisive engagement the rebels were dispersed into small bands and driven eastward along the boundary line toward Nogales。
It was the destiny of Forlorn River； however； never to return to the slow； sleepy tenor of its former existence。 Belding's predictions came true。 That straggling line of home…seekers was but a forerunner of the real invasion of Altar Valley。 Refugees from Mexico and from Casita spread the word that water and wood and grass and land were to be had at Forlorn River； and as if by magic the white tents and red adobe houses sprang up to glisten in the sun。
Belding was happier than he had been for a long time。 He believed that evil days for Forlorn River； along with the apathy and lack of enterprise； were in the past。 He hired a couple of trustworthy Mexicans to ride the boundary line； and he settled down to think of ranching and irrigation and mining projects。 Every morning he expected to receive some word form Sonoyta or Yuma； telling him that Yaqui had guided his party safely across the desert。
Belding was simple…minded； a man more inclined to action than reflection。 When the complexities of life hemmed him in； he groped his way out； never quite understanding。 His wife had always been a mystery to him。 Nell was sunshine most of the time； but； like the sun…dominated desert； she was subject to strange changes； wilful； stormy； sudden。 It was enough for Belding now to find his wife in a lighter； happier mood； and to see Nell dreamily turning a ring round and round the third finger of her left hand and watching the west。 Every day both mother and daughter appeared farther removed from the past darkly threatening days。 Belding was hearty in his affections； but undemonstrative。 If there was any sentiment in his make…up it had an outlet in his memory of Blanco Diablo and a longing to see him。 Often Belding stopped his work to gaze out over the desert toward the west。 When he thought of his rangers and Thorne and Mercedes he certainly never forgot his horse。 He wondered if Diablo was running； walking； resting； if Yaqui was finding water and grass。
In March； with the short desert winter over； the days began to grow warm。 The noon hours were hot； and seemed to give promise of the white summer blaze and blasting furnace wind soon to come。 No word was received from the rangers。 But this caused Belding no concern； and it seemed to him that his women folk considered no news good news。
Among the many changes coming to pass in Forlorn River were the installing of post…office service and the building of a mescal drinking…house。 Belding had worked hard for the post office； but he did not like the idea of a saloon for Forlorn River。 Still； that was an inevitable evil。 The Mexicans would have mescal。 Belding had kept the little border hamlet free of an establishment for distillation of the fiery cactus drink。 A good many Americans drifted into Forlorn Riverminers； cowboys； prospectors； outlaws； and others of nondescript character； and these men； of course； made the saloon； which was also an inn； their headquarters。 Belding； with Carter and other old residents； saw the need of
