foot。 The thick grass hid his trail； the dense growth of oaks in the opening would serve as a barrier to keep Wrangle in； if； indeed； the luxuriant browse would not suffice for that。 So Venters； leaving Whitie with the horse； called Ring to his side； and； rifle in hand； worked his way out to the open。 A careful photographing in mind of the formation of the bold outlines of rimrock assured him he would be able to return to his retreat even in the dark。
Bunches of scattered sage covered the center of the canyon； and among these Venters threaded his way with the step of an Indian。 At intervals he put his hand on the dog and stopped to listen。 There was a drowsy hum of insects； but no other sound disturbed the warm midday stillness。 Venters saw ahead a turn； more abrupt than any yet。 Warily he rounded this corner； once again to halt bewildered。
The canyon opened fan…shaped into a great oval of green and gray growths。 It was the hub of an oblong wheel； and from it； at regular distances； like spokes； ran the outgoing canyons。 Here a dull red color predominated over the fading yellow。 The corners of wall bluntly rose； scarred and scrawled； to taper into towers and serrated peaks and pinnacled domes。
Venters pushed on more heedfully than ever。 Toward the center of this circle the sage…brush grew smaller and farther apart He was about to sheer off to the right； where thickets and jumbles of fallen rock would afford him cover； when he ran right upon a broad cattle trail。 Like a road it was； more than a trail； and the cattle tracks were fresh。 What surprised him more； they were wet！ He pondered over this feature。 It had not rained。 The only solution to this puzzle was that the cattle had been driven through water； and water deep enough to wet their legs。
Suddenly Ring growled low。 Venters rose cautiously and looked over the sage。 A band of straggling horsemen were riding across the oval。 He sank down； startled and trembling。 〃Rustlers！〃 he muttered。 Hurriedly he glanced about for a place to hide。 Near at hand there was nothing but sage…brush。 He dared not risk crossing the open patches to reach the rocks。 Again he peeped over the sage。 The rustlersfourfiveseveneight in all； were approaching； but not directly in line with him。 That was relief for a cold deadness which seemed to be creeping inward along his veins。 He crouched down with bated breath and held the bristling dog。
He heard the click of iron…shod hoofs on stone； the coarse laughter of men； and then voices gradually dying away。 Long moments passed。 Then he rose。 The rustlers were riding into a canyon。 Their horses were tired； and they had several pack animals； evidently they had traveled far。 Venters doubted that they were the rustlers who had driven the red herd。 Olding's band had split。 Venters watched these horsemen disappear under a bold canyon wall。
The rustlers had come from the northwest side of the oval。 Venters kept a steady gaze in that direction； hoping； if there were more； to see from what canyon they rode。 A quarter of an hour went by。 Reward for his vigilance came when he descried three more mounted men； far over to the north。 But out of what canyon they had ridden it was too late to tell。 He watched the three ride across the oval and round the jutting red corner where the others had gone。
〃Up that canyon！〃 exclaimed Venters。 〃Oldring's den！ I've found it！〃
A knotty point for Venters was the fact that the cattle tracks all pointed west。 The broad trail came from the direction of the canyon into which the rustlers had ridden； and undoubtedly the cattle had been driven out of it across the oval。 There were no tracks pointing the other way。 It had been in his mind that Oldring had driven the red herd toward the rendezvous； and not from it。 Where did that broad trail come down into the pass； and where did it lead？ Venters knew he wasted time in pondering the question； but it held a fascination not easily dispelled。 For many years Oldring's mysterious entrance and exit to Deception Pass had been all…absorbing topics to sage…riders。
All at once the dog put an end to Venters's pondering。 Ring sniffed the air； turned slowly in his tracks with a whine； and then growled。 Venters wheeled。 Two horsemen were within a hundred yards； coming straight at him。 One； lagging behind the other； was Oldring's Masked Rider。
Venters cunningly sank； slowly trying to merge into sage…brush。 But； guarded as his action was； the first horse detected it。 He stopped short； snorted； and shot up his ears。 The rustler bent forward； as if keenly peering ahead。 Then； with a swift sweep； he jerked a gun from its sheath and fired。
The bullet zipped through the sage…brush。 Flying bits of wood struck Venters； and the hot； stinging pain seemed to lift him in one leap。 Like a flash the blue barrel of his rifle gleamed level and he shot oncetwice。
The foremost rustler dropped his weapon and toppled from his saddle； to fall with his foot catching in a stirrup。 The horse snorted wildly and plunged away； dragging the rustler through the sage。
The Masked Rider huddled over his pommel slowly swaying to one side； and then； with a faint； strange cry； slipped out of the saddle。
CHAPTER V。 THE MASKED RIDER
Venters looked quickly from the fallen rustlers to the canyon where the others had disappeared。 He calculated on the time needed for running horses to return to the open； if their riders heard shots。 He waited breathlessly。 But the estimated time dragged by and no riders appeared。 Venters began presently to believe that the rifle reports had not penetrated into the recesses of the canyon； and felt safe for the immediate present。
He hurried to the spot where the first rustler had been dragged by his horse。 The man lay in deep grass； dead； jaw fallen； eyes protrudinga sight that sickened Venters。 The first man at whom he had ever aimed a weapon he had shot through the heart。 With the clammy sweat oozing from every pore Venters dragged the rustler in among some boulders and covered him with slabs of rock。 Then he smoothed out the crushed trail in grass and sage。 The rustler's horse had stopped a quarter of a mile off and was grazing。
When Venters rapidly strode toward the Masked Rider not even the cold nausea that gripped him could wholly banish curiosity。 For he had shot Oldring's infamous lieutenant； whose face had never been seen。 Venters experienced a grim pride in the feat。 What would Tull say to this achievement of the outcast who rode too often to Deception Pass？
Venters's curious eagerness and expectation had not prepared him for the shock he received when he stood over a slight； dark figure。 The rustler wore the black mask that had given him his name； but he had no weapons。 Venters glanced at the drooping horse； there were no gun…sheaths on the saddle。
〃A rustler who didn't pack guns！〃 muttered Venters。 〃He wears no belt。 He couldn't pack guns in that rig。。。。Strange！〃
A low； gasping intake of breath and a sudden twitching of body told Venters the rider still lived。
〃He's alive！。。。I've got to stand here and watch him die。 And I shot an unarmed man。〃
Shrinkingly Venters removed the rider's wide sombrero and the black cloth mask。 This action disclosed bright chestnut hair； inclined to curl； and a white； youthful face。 Along the lower line of cheek and jaw was a clear demarcation； where the brown of tanned skin met the white that had been hidden from the sun。
〃Oh； he's only a boy！。。。What！ Can he be Oldring's Masked Rider？〃
The boy showed signs of returning consciousness。 He stirred； his lips moved； a small brown hand clenched in his blouse。
Venters knelt with a gathering horror of his deed。 His bullet had entered the rider's right breast； high up to the shoulder。 With hands that shook； Venters untied a black scarf and ripped open the blood…wet blouse。
First he saw a gaping hole； dark red against a whiteness of skin； from which welled a slender red stream。 Then the graceful； beautiful swell of a woman's breast！
〃A woman！〃 he cried。 〃A girl！。。。I've killed a girl！〃
She suddenly opened eyes that transfixed Venters。 They were fathomless blue。 Consciousness of death was there； a blended terror and pain； but no consciousness of sight。 She did not see Venters。 She stared into the unknown。
Then came a spasm of vitality。 She writhed in a torture of reviving strength； and in her convulsions she almost tore from Ventner's grasp。 Slowly she relaxed and sank partly back。 The ungloved hand sought the wound； and pressed so hard that her wrist half buried itself in her bosom。 Blood trickled between her spread fingers。 And she looked at Venters with eyes that saw him。
He cursed himself and the unerring aim of which he had been so proud。 He had seen that look in the eyes of a crippled antelope which he was about to finish with his knife。 But in her it had infinitely morea revelation of mortal spirit。 The instinctive bringing to life was there； and the divining helplessness and the terrible accusation of the stricken。
〃Torgive me！ I didn't know！〃 burst out Venters。
〃You shot meyou've killed me！〃 she whispered； in panting gasps。 Upon her lips appeared a fluttering； bloody froth。 By that Venters knew the air in her lungs was mixing with blood。 〃Oh； I knewit wouldcomesome day！。。。Oh； the burn！。。。Hold meI'm sinkingit's all dark。。。。Ah； God！。。。Mercy〃
Her rigidity loosened in one long quiver and she lay back limp； still； white as snow； with closed eyes。
Venters thought then that she died。 But the faint pulsation of her breast assured him that life yet lingered。 Death seemed only a matter of moments； for the bullet had gone clear through her。 Nevertheless； he tore sageleaves from a bush； and； pressing them tightly over her wounds； he bound the black scarf round her shoulder； tying it securely under her arm。 Then he closed the blouse； hiding from his sight that blood…stained； accusing breast。
〃Whatnow？〃 he questioned； with flying mind。 〃I must get out of here。 She's dyingbut I can't leave her。〃
He rapidly surveyed the sage to the north and made out no animate object。 Then he picked up the girl's sombrero and the mask。 This time the mask gave him as great a shock as when he first removed it from her face。 For in the woman he had forgotten the rustler；
