The mutterings above the mountains now grew rapidly louder and while the two hovered over the fire, a thunder-squall, rolling wildly down the eastern slope, burst over the Gap. Its sudden fury put aside for a time all question of moving, and Nan’s face took on a grave expression as she looked in the firelight at her companion, thinking of how far such a storm might imperil their situation, how far cut off their already narrow chance of escape.

De Spain––reclining close beside her, looking into the depths of her eyes as the flickering blaze revealed them, drying himself in their warmth and light, eating and drinking of their presence on the mountainside alone with him, and pledged to him, his protection, and his fortunes against the world––apparently thought of nothing beyond the satisfaction of the moment. The wind drove the storm against the west side of the huge granite peak under which they were sheltered and gave them no present trouble in their slender recess. But Nan knew even better than her companion 349 the fickle fury of a range storm, and understood uncomfortably well how a sudden shift might, at any moment, lay their entire path open to its fierceness. She warned de Spain they must be moving, and, freshened by the brief rest, they set out toward El Capitan.

Their trail lay along granite levels of comparatively good going and, fleeing from the squall, they had covered more than half the distance that separated them from the cliff, when a second thunder-storm, seeming to rush in from the desert, burst above their heads. Drenched with rain, they were forced to draw back under a projecting rock. In another moment the two storms, meeting in the Gap, crashed together. Bolt upon bolt of lightning split the falling sheets of water, and thunder, exploding in their faces, stunned and deafened them.

Mountain peaks, played on by the wild light, leaped like spectres out of the black, and granite crags, searched by blazing shafts, printed themselves in ghostly flames on the retina; thunder, searching unnumbered gorges, echoed beneath the sharper crashes in one long, unending roll, and far out beyond the mountains the flooded desert tossed on a dancing screen into the glare, rippled like a madcap sea, and flashed in countless sheets of blinding facets. As if an unseen hand had 350 touched a thousand granite springs above the Gap, every slender crevice spouted a stream that shot foaming out from the mountainsides. The sound of moving waters rose in a dull, vast roar, broken by the unseen boom of distant falls, launching huge masses of water into caverns far below. The storm-laden wind tore and swirled among the crowded peaks, and above all the angry sky moaned and quivered in the rage of the elements.

Nan leaned within de Spain’s arm. “If this keeps up,” he said after some time, “our best play is to give up crossing to-night. We might hide somewhere on the mountain to-morrow, and try it toward evening.”

“Yes, if we have to,” she answered. But he perceived her reluctant assent. “What I am afraid of, Henry, is, if they were to find us. You know what I mean.”

“Then we won’t hide,” he replied. “The minute we get the chance we will run for it. This is too fierce to last long.”

“Oh, but it’s November!” Nan reminded him apprehensively. “It’s winter; that’s what makes it so cold. You never can tell in November.”

“It won’t last all night, anyway,” he answered with confidence.

Despite his assurance, however, it did last all 351 night, and it was only the lulls between the sharp squalls that enabled them to cover the trail before daylight. When they paused before El Capitan the fury of the night seemed largely to have exhausted itself, but the overcharged air hung above the mountains, trembling and moaning like a bruised and stricken thing. Lightning, playing across the inky heavens, blazed in constant sheets from end to end of the horizon. Its quivering glare turned the wild night into a kind of ghastly, uncertain day. Thunder, hoarse with invective, and hurled mercilessly back and forth by the fitful wind, drew farther and farther into the recess of the mountains, only to launch its anger against its own imprisoned echoes. Under it all the two refugees, high on the mountainside, looked down on the flooding Gap.

Their flight was almost ended. Only the sheer cliff ahead blocked their descent to the aspen grove. De Spain himself had already crossed El Capitan once, and he had done it at night––but it was not, he was compelled to remind himself, on a night like this. It seemed now a madman’s venture and, without letting himself appear to do so, he watched Nan’s face as the lightning played over it, to read if he could, unsuspected, whether she still had courage for the undertaking. She regarded him so collectedly, whether answering 352 a question or asking one, that he marvelled at her strength and purpose. Hardly a moment passed after they had started until the eastern sky lightened before the retreating storm, and with the first glimmer of daylight, the two were at the beginning of the narrow foothold which lay for half a mile between them and safety.

Here the El Capitan trail follows the face of the almost vertical wall which, rising two thousand feet in the air, fronts the gateway of Morgan’s Gap.

They started forward, de Spain ahead. There was nothing now to hurry them unduly, and everything to invite caution. The footholds were slippery, rivulets still crossed the uncertain path, and fragments of rock that had washed down on the trail, made almost every step a new hazard. The face of El Capitan presents, midway, a sharp convex. Just where it is thrown forward in this keen angle, the trail runs out almost to a knife-edge, and the mountain is so nearly vertical that it appears to overhang the floor of the valley.

They made half the stretch of this angle with hardly a misstep, but the advance for a part of the way was a climb, and de Spain, turning once to speak to Nan, asked her for her rifle, that he might carry it with his own. What their story might have been had she given it to him, none 353 can tell. But Nan, holding back, refused to let him relieve her. The dreaded angle which had haunted de Spain all night was safely turned on hands and knees and, as they rounded it toward the east, clouds scudding over the open desert broke and shot the light of dawn against the beetling arÊte.

De Spain turned in some relief to point to the coming day. As he did so a gust of wind, sweeping against the sheer wall, caught him off his guard. He regained his balance, but a stone, slipping underfoot, tipped him sidewise, and he threw himself on his knees to avoid the dizzy edge. As he fell forward he threw up his hand to save his hat, and in doing so released his rifle, which lay under his hand on the rock. Before he could recover it the rifle slipped from reach. In the next instant he heard it bouncing from rock to rock, five hundred feet below.

Greatly annoyed and humiliated, he regained his feet and spoke with a laugh to reassure Nan. Just as she answered not to worry, a little singing scream struck their ears; something splashed suddenly close at hand against the rock wall; chips scattered between them. From below, the sound of a rifle report cracked against the face of the cliff. They were so startled, so completely amazed that they stood motionless. De Spain looked 354 down and over the uneven floor of the Gap. The ranch-houses, spread like toys in the long perspective, lay peacefully revealed in the gray of the morning. Among the dark pine-trees he could discern Nan’s own home. Striving with the utmost keenness of vision to detect where the shot had come from, de Spain could discover no sign of life around any of the houses. But in another moment the little singing scream came again, the blow of the heavy slug against the splintering rock was repeated, the distant report of the rifle followed.

“Under fire,” muttered de Spain. He looked questioningly at Nan. She herself, gazing across the dizzy depths, was searching for the danger-point. A third shot followed at a seemingly regular interval––the deliberate interval needed by a painstaking marksman working out his range and taking his time to find it. De Spain watched Nan’s search anxiously. “We’d better keep moving,” he said. “Come! whoever is shooting can follow us a hundred yards either way.” In front of de Spain a fourth bullet struck the rock. “Nan,” he muttered, “I’ve got you into a fix. If we can’t stop that fellow he is liable to stop us. Can you see anything?” he asked, waiting for her to come up.

“Henry!” She was looking straight down into 355 the valley, and laid her hand on de Spain’s shoulder. “Is there anything moving on the ridge––over there––see––just east of Sassoon’s ranch-house?”

De Spain, his eyes bent on the point Nan indicated, drew her forward to a dip in the trail which, to one stretched flat, afforded a slight protection. He made her lie down, and just beyond her refuge chose a point where the path, broadening a little and rising instead of sloping toward the outer edge, gave him a chance to brace himself between two rocks. Flattened there like a target in mid-air, he threw his hat down to Nan and, resting on one knee, waited for the shot that should tumble him down El Capitan or betray the man bent on killing him. Squalls of wind, sweeping into the Gap and sucked upward on the huge expanse of rock below, tossed his hair and ballooned his coat as he buttoned it. Another bullet, deliberately aimed, chipped the rock above him. Nan, agonizing in her suspense, cried out she must join him and go with him if he went. He steadied her apprehension and with a few words reminded her, as a riflewoman, what a gamble every shot at a height such as they occupied, and with such a wind, must be. He reminded her, too, it was much easier to shoot down than up, but all the time he was searching for the flash that should 356 point the assassin. A bullet struck again viciously close between them. De Spain spoke slowly: “Give me your rifle.” Without turning his head he held out his hand, keeping his eyes rigidly on the suspicious spot on the ridge. “How far is it to that road, Nan?”

She looked toward the faint line that lay in the deep shadows below. “Three hundred yards.”

“Nan, if it wasn’t for you, I couldn’t travel this country at all,” he remarked with studious unconcern. “Last time I had no ammunition––this time, no rifle––you always have what’s needed. How high are we, Nan?”

“Seven hundred feet.”

“Elevate for me, Nan, will you?”

“Remember the wind,” she faltered, adjusting the sight as he had asked.

With the cautioning words she passed the burnished weapon, glittering yet with the rain-drops, into his hand. A flash came from the distant ridge. Throwing the rifle to his shoulder, de Spain covered a hardly perceptible black object on the trail midway between Sassoon’s ranch-house and a little bridge which he well remembered––he had crossed it the night he dragged Sassoon into town. It seemed a long time that he pressed the rifle back against his shoulder and held his eye along the barrel. He was wondering as he 357 covered the crouching man with the deadly sight which of his enemies this might be. He even slipped the rifle from his shoulder and looked long and silently at the black speck before he drew the weapon back again into place. Then he fired before Nan could believe he had lined the sights. Once, twice, three times his hand fell and rose sharply on the lever, with every mark of precision, yet so rapidly Nan could not understand how he could discover what his shots were doing.

The fire came steadily back, and deliberately, without the least intimation of being affected by de Spain’s return. It was a duel shorn of every element of equality, with an assassin at one end of the range, and a man flattened half-way up the clouds against El Capitan at the other, each determined to kill the other before he should stir one more foot.

Far above, an eagle, in morning flight, soared majestically out from a jutting crag and circled again and again in front of El Capitan, while the air sang with the whining dice that two gamblers against death threw across the gulf between them. Nan, half hidden in her trough of rock, watched the great bird poise and wheel above the deadly firing, and tried to close her eyes to the figure of de Spain above her, fighting for her life and his own.

She had never before seen a man shooting to kill another. The very horror of watching de Spain, at bay among the rocks, fascinated her. Since the first day they had met she had hardly seen a rifle in his hands.

Realizing how slightly she had given thought to him or to his skill at that time, she saw now, spellbound, how a challenge to death, benumbing her with fear, had transformed him into a silent, pitiless foeman, fighting with a lightning-like decision that charged every motion with a fatality for his treacherous enemy. Her rifle, at his shoulder, no longer a mere mechanism, seemed in his hands something weightless, sensible, alive, a deadly part of his arm and eye and brain. There was no question, no thought of adjusting or handling or haste in his fire, but only an incredible swiftness and sureness that sent across the thin-aired chasm a stream of deadly messengers to seek a human life. She could only hope and pray, without even forming the words, that none of her blood were behind the other rifle, for she felt that, whoever was, could never escape.

She tried not to look. The butt of the heating rifle lay close against the red-marked cheek she knew so well, and to the tips of the fingers every particle of the man’s being was alive with strength and resource. Some strange fascination drew her 359 senses out toward him as he knelt and threw shot after shot at the distant figure hidden on the ridge. She wanted to climb closer, to throw herself between him and the bullets meant for him. She held out her arms and clasped her hands toward him in an act of devotion. Then while she looked, breathlessly, he took his eyes an instant from the sights. “He’s running!” exclaimed de Spain as the rifle butt went instantly back to his cheek. “Whoever he is, God help him now!”

The words were more fearful to Nan than an imprecation. He had driven his enemy from the scant cover of a rut in the trail, and the man was fleeing for new cover and for life. The speck of black in the field of intense vision was moving rapidly toward the ranch-house. Bullet after bullet pitilessly led the escaping wretch. Death dogged every eager footfall. Suddenly de Spain jerked the rifle from his cheek, threw back his head, and swept his left hand across his straining eyes. Once more the rifle came up to place and, waiting for a heartbeat, to press the trigger, he paused an instant. Flame shot again in the gray morning light from the hot muzzle. The rifle fell away from the shoulder. The black speck running toward the ranch-house stumbled, as if stricken by an axe, and sprawled headlong on the 360 trail. Throwing the lever again like lightning, de Spain held the rifle back to his cheek.

He did not fire. Second after second he waited, Nan, lying very still, watching, mute, the dull-red mark above the wet rifle butt. No one had need to tell her what had happened. Too well she read the story in de Spain’s face and in what she saw, as he knelt, perfectly still, only waiting to be sure there was no ruse. She watched the rifle come slowly down, unfired, and saw his drawn face slowly relax. Without taking his eyes off the sprawling speck, he rose stiffly to his feet. As if in a dream she saw his hand stretched toward her and heard, as he looked across the far gulf, one word: “Come!”

They reached the end of the trail. De Spain, rifle in hand, looked back. The sun, bursting in splendor across the great desert, splashed the valley and the low-lying ridge with ribboned gold. Farther up the Gap, horsemen, stirred by the firing, were riding rapidly down toward Sassoon’s ranch-house. But the black thing in the sunshine lay quite still.
