led with the meaning of it allthe nightthe silence the flightand the wonderful Indian stealing with the slow inevitableness of doom upon another sentinel。 An hour passed and Gale seemed to have become deadened to all sense of hearing。 There were no more sounds in the world。 The desert was as silent as it was black。 Yet again came that strange change in the tensity of Gale's ear…strain； a check； a break； a vibrationand this time the sound did not go nameless。 It might have been moan of wind or wail of far…distant wolf； but Gale imagined it was the strangling death…cry of another guard； or that strange； involuntary utterance of the Yaqui。 Blanco Sol trembled in all his great frame； and then Gale was certain the sound was not imagination。
That certainty； once for all； fixed in Gale's mind the mood of his flight。 The Yaqui dominated the horses and the rangers。 Thorne and Mercedes were as persons under a spell。 The Indian's strange silence； the feeling of mystery and power he seemed to create； all that was incomprehensible about him were emphasized in the light of his slow； sure； and ruthless action。 If he dominated the others； surely he did more for Galecolored his thoughtspresage the wild and terrible future of that flight。 If Rojas embodied all the hatred and passion of the peonscourged slave for a thousand yearsthen Yaqui embodied all the darkness； the cruelty； the white； sun…heated blood； the ferocity； the tragedy of the desert。
Suddenly the Indian stalked out of the gloom。 He mounted Diablo and headed across the river。 Once more the line of moving white shadows stretched out。 The soft sand gave forth no sound at all。 The glimmering campfires sank behind the western bank。 Yaqui led the way into the willows； and there was faint swishing of leaves； then into the mesquite； and there was faint rustling of branches。 The glimmering lights appeared again； and grotesque forms of saguaros loomed darkly。 Gale peered sharply along the trail； and； presently； on the pale sand under a cactus； there lay a blanketed form； prone； outstretched； a carbine clutched in one hand； a cigarette； still burning； in the other。
The cavalcade of white horses passed within five hundred yards of campfires； around which dark forms moved in plain sight。 Soft pads in sand； faint metallic tickings of steel on thorns； low； regular breathing of horsesthese were all the sounds the fugitives made； and they could not have been heard at one…fifth the distance。 The lights disappeared from time to time； grew dimmer； more flickering； and at last they vanished altogether。 Belding's fleet and tireless steeds were out in front； the desert opened ahead wide； dark； vast。 Rojas and his rebels were behind； eating； drinking； careless。 The somber shadow lifted from Gale's heart。 He held now an unquenchable faith in the Yaqui。 Belding would be listening back there along the river。 He would know of the escape。 He would tell Nell； and then hide her safely。 As Gale accepted a strange and fatalistic foreshadowing of toil； blood； and agony in this desert journey； so he believed in Mercedes's ultimate freedom and happiness； and his own return to the girl who had grown dearer than life。
A cold； gray dawn was fleeing before a rosy sun when Yaqui halted the march at Papago Well。 The horses were taken to water； then led down the arroyo into the grass。 Here packs were slipped； saddles removed。 Mercedes was cold； lame； tired； but happy。 It warmed Gale's blood to look at her。 The shadow of fear still lay in her eyes； but it was passing。 Hope and courage shone there； and affection for her ranger protectors and the Yaqui； and unutterable love for the cavalryman。 Jim Lash remarked how cleverly they had fooled the rebels。
〃Shore they'll be comin' along；〃 replied Ladd。
They built a fire； cooked and ate。 The Yaqui spoke only one word： 〃Sleep。〃 Blankets were spread。 Mercedes dropped into a deep slumber； her head on Thorne's shoulder。 Excitement kept Throne awake。 The two rangers dozed beside the fire。 Gale shared the Yaqui's watch。 The sun began to climb and the icy edge of dawn to wear away。 Rabbits bobbed their cotton tails under the mesquite。 Gale climbed a rocky wall above the arroyo bank； and there； with command over the miles of the back…trail； he watched。
It was a sweeping； rolling； wrinkled； and streaked range of desert that he saw； ruddy in the morning sunlight； with patches of cactus and mesquite rough…etched in shimmering gloom。 No Name Mountains split the eastern sky； towering high； gloomy； grand； with purple veils upon their slopes。 They were forty miles away and looked five。 Gale thought of the girl who was there under their shadow。
Yaqui kept the horses bunched； and he led them from one little park of galleta grass to another。 At the end of three hours he took them to water。 Upon his return Gale clambered down from his outlook； the rangers grew active。 Mercedes was awakened； and soon the party faced westward； their long shadows moving before them。 Yaqui led with Blanco Diablo in a long； easy lope。 The arroyo washed itself out into flat desert； and the greens began to shade into gray； and then the gray into red。 Only sparse cactus and weathered ledges dotted the great low roll of a rising escarpment。
Yaqui suited the gait of his horse to the lay of the land； and his followers accepted his pace。 There were canter and trot； and swift walk and slow climb； and long swingmiles up and down and forward。 The sun soared hot。 The heated air lifted； and incoming currents from the west swept low and hard over the barren earth。 In the distance； all around the horizon； accumulations of dust seemed like ranging； mushrooming yellow clouds。
Yaqui was the only one of the fugitives who never looked back。 Mercedes did it the most。 Gale felt what compelled her； he could not resist it himself。 But it was a vain search。 For a thousand puffs of white and yellow dust rose from that backward sweep of desert； and any one of them might have been blown from under horses' hoofs。 Gale had a conviction that when Yaqui gazed back toward the well and the shining plain beyond； there would be reason for it。 But when the sun lost its heat and the wind died down Yaqui took long and careful surveys westward from the high points on the trail。 Sunset was not far off； and there in a bare； spotted valley lay Coyote Tanks； the only waterhole between Papago Well and the Sonoyta Oasis。 Gale used his glass； told Yaqui there was no smoke； no sign of life； still the Indian fixed his falcon eyes on distant spots looked long。 It was as if his vision could not detect what reason or cunning or intuition； perhaps an instinct； told him was there。 Presently in a sheltered spot； where blown sand had not obliterated the trail； Yaqui found the tracks of horses。 The curve of the iron shoes pointed westward。 An intersecting trail from the north came in here。 Gale thought the tracks either one or two days old。 Ladd said they were one day。 The Indian shook his head。
No farther advance was undertaken。 The Yaqui headed south and traveled slowly； climbing to the brow of a bold height of weathered mesa。 There he sat his horse and waited。 No one questioned him。 The rangers dismounted to stretch their legs； and Mercedes was lifted to a rock； where she rested。 Thorne had gradually yielded to the desert's influence for silence。 He spoke once or twice to Gale； and occasionally whispered to Mercedes。 Gale fancied his friend would soon learn that necessary speech in desert travel meant a few greetings； a few words to make real the fact of human companionship； a few short； terse terms for the business of day or night； and perhaps a stern order or a soft call to a horse。
The sun went down； and the golden； rosy veils turned to blue and shaded darker till twilight was there in the valley。 Only the spurs of mountains； spiring the near and far horizon； retained their clear outline。 Darkness approached； and the clear peaks faded。 The horses stamped to be on the move。
〃Malo！〃 exclaimed the Yaqui。
He did not point with arm； but his falcon head was outstretched； and his piercing eyes gazed at the blurring spot which marked the location of Coyote Tanks。
〃Jim； can you see anything？〃 asked Ladd。
〃Nope； but I reckon he can。〃
Darkness increased momentarily till night shaded the deepest part of the valley。
Then Ladd suddenly straightened up； turned to his horse； and muttered low under his breath。
〃I reckon so；〃 said Lash； and for once his easy； good…natured tone was not in evidence。 His voice was harsh。
Gale's eyes； keen as they were； were last of the rangers to see tiny； needle…points of light just faintly perceptible in the blackness。
〃Laddy！ Campfires？〃 he asked； quickly。
〃Shore's you're born； my boy。〃
〃How many？〃
Ladd did not reply； but Yaqui held up his hand； his fingers wide。 Five campfires！ A strong force of rebels or raiders or some other desert troop was camping at Coyote Tanks。
Yaqui sat his horse for a moment； motionless as stone； his dark face immutable and impassive。 Then he stretched wide his right arm in the direction of No Name Mountains； now losing their last faint traces of the afterglow； and he shook his head。 He made the same impressive gesture toward the Sonoyta Oasis with the same somber negation。
Thereupon he turned Diablo's head to the south and started down the slope。 His manner had been decisive； even stern。 Lash did not question it； nor did Ladd。 Both rangers hesitated； however； and showed a strange； almost sullen reluctance which Gale had never seen in them before。 Raiders were one thing； Rojas was another； Camino del Diablo still another； but that vast and desolate and unwatered waste of cactus and lava； the Sonora Desert； might appal the stoutest heart。 Gale felt his own sinkfelt himself flinch。
〃Oh； where is he going？〃 cried Mercedes。 Her poignant voice seemed to break a spell。
〃Shore； lady； Yaqui's goin' home；〃 replied Ladd； gently。 〃An' considerin' our troubles I reckon we ought to thank God he knows the way。〃
They mounted and rode down the slope toward the darkening south。
Not until night travel was obstructed by a wall of cactus did the Indian halt to make a dry camp。 Water and gra
