In vain Bob looked about him for the horses, or for signs of them. They were nowhere to be seen. Saleratus Bill, reading his perplexity, grinned sardonically.

"Yore friends might come in here," said he, evidently not unwilling to expose to Bob the full hopelessness of the latter's case. "And if so, they can trail us in; _and then trail us out again!_" He pointed to the lacets of the trail up the north wall. He grinned again. "You and I'd just crawl down a mile of mine shaft."

Having thus, to his satisfaction, impressed Bob with the utter futility of an attempt to escape, Saleratus Bill led the way back to the deserted village. There he turned deliberately on his captive.

"Now, young feller, you listen to me," said he. "Don't you try no monkey business. There won't be no questions asked, none whatever. As long as you set and look at the scenery, you won't come to no harm; but the minute you make even a bluff at gettin' funny--even if yore sorry the next minute--I'll shoot. And don't you never forget and try to get nearer to me than three paces. Don't forget that! I don't rightly want to hurt you; but I'd just as leave shoot you as anybody else."

To this view of the situation Bob gave the expected a.s.sent.

The next three days were ones of routine. Saleratus Bill spent his time rolling brown-paper cigarettes at a spot that commanded both trails. Bob was instructed to keep in sight. He early discovered the cheering fact that trout were to be had in the gla.s.s-green pools; and so spent hours awkwardly manipulating an improvised willow pole equipped with the short line and the Brown Hackle without which no mountaineer ever travels the Sierras. His bound elbows and the crudity of his tackle lost him many fish. Still, he caught enough for food; and his mind was busy.

Canva.s.sing the possibilities, Bob could not but admit that Saleratus Bill knew his job. The river was certain death, and led nowhere except into mysterious and awful granite gorges; the outlets by roads were well in sight. For one afternoon Bob seriously contemplated hazarding a personal encounter. He conceived that in some manner he could get rid of his bonds at night; that Saleratus Bill must necessarily sleep; and that there might be a chance to surprise the gun-man then. But when night came, Saleratus Bill disappeared into the outer darkness; nor did he return until morning. He might have spent the hours camped under the trees of the more remote meadow, whence in the brilliant moonlight he could keep tabs on the trails, or he might be lying near at hand; Bob had no means of telling. Certainly, again the young man reluctantly acknowledged to himself, Saleratus Bill knew his job!

Nevertheless, as the days slipped by; and Bob's physical strength returned in its full measure, his active and bold spirit again took the initiative. A slow anger seized possession of him. The native combative stubbornness of the race a.s.serted itself, the necessity of doing something, the inability tamely to submit to imposed circ.u.mstances.

Bob's careful a.n.a.lysis of the situation as a whole failed to discover any feasible plan. Therefore he abandoned trying to plan ahead, and fell back on those always-ready and comfortable aphorisims of the adventurous--"sufficient unto the day is the evil thereof," and "one thing at a time." Obviously, the first thing to do was to free his arms; after that he would see what he would see.

Every evening Saleratus Bill took the candle and departed, leaving Bob to find his own way to his bunk. This was the time to cut his bonds; if at all. Unfortunately Bob could find nothing against which to cut them.

Saleratus Bill had carefully removed every abrasive possibility in the two rooms. Bob very wisely relinquished the idea of pa.s.sing the threshold in search of a suitable rock or piece of tin. He had no notion of risking a bullet until something was likely to be gained by it.

Finally his cogitations brought him an idea. Saleratus Bill was attentive enough to such of the simple creature comforts as were within his means. Bob's pipe had been well supplied with tobacco. On the fourth evening Bob filled it just as his jailor was about to take away the candle for the night.

"Just a minute," said Bob. "Let me have a light."

Bill set the candle on the table again, and retired the three paces which he never forgot rigidly to maintain between himself and his captive. Bob thereupon lit his pipe and nodded his thanks. As soon as Saleratus Bill had well departed, however, he retired to his bunk room, shutting the door carefully after him. There, with great care, he deliberately set to work to coax into flame a small fire on the old hearth, using as fuel the rounds of a broken chair, and as ignition the glowing coal in the bowl of his pipe. Before the hearth he had managed to hang the heavy quilt from his bunk, so that the flicker of the flames should not be visible from the outside.

The little fire caught, blazed for a few moments, and fell to a steady glow. Bob fished out one of the chair rungs, jammed the cool end firmly in one of the open cracks between the timbers of the room, turned his back, and deliberately pressed the band around his elbows against the live coal.

A smell of burning cloth immediately filled the air. After a moment the coal went out. Bob replaced the charred rung in the fire, extracted another, and repeated the operation.

It was exceedingly difficult to gauge the matter accurately, as Bob soon found out to his cost. He managed to burn more holes in his garment--and himself--than in the bonds. However, he kept at it, and after a half hour's steady and patient effort he was able to snap asunder the last strands. He stretched his arms over his head in an ecstasy of physical freedom.

That was all very well, but what next? Bob was suddenly called to a decision which had up to that moment seemed inconceivably remote.

Heretofore, an apparent impossibility had separated him from it. Now that impossibility was achieved.

A moment's thought convinced him of the senseless hazard of attempting to slip out through any of the doors or windows. The moon was bright, and Saleratus Bill would have taken his precautions. Bob attacked the floor. Several boards proved to be loose. He pried them up cautiously, and so was enabled to drop through into the open s.p.a.ce beneath the house. Thence it was easy to crawl away. Saleratus Bill's precautions were most likely taken, Bob argued to himself, with a view toward a man bound at the elbows, not to a man with two hands. In this he was evidently correct, for after a painful effort, he found himself among the high gra.s.ses of the meadow.

There were now, as he recognized, two courses open to him: he could either try to discover Saleratus Bill's sleeping place and by surprise overpower that worthy as he slept; or he could make the best of the interim before his absence was discovered to get as far away as possible. Both courses had obvious disadvantages. The most immediate to the first alternative was the difficulty, failing some clue, of finding Saleratus Bill's sleeping place without too positive a risk of discovery; the most immediate to the second was the difficulty of getting to the other side of the river. As Saleratus Bill might be at any one of a thousand places, in or out of doors; whereas the river could be crossed only by the bridge. Bob, without hesitation, chose the latter.

Therefore he made his way cautiously to that structure. It proved to be lying in broad moonlight. As it const.i.tuted the only link with the outside world to the south, Bob could not doubt that his captor had arranged to keep it in sight.

The bridge was, as has been said, suspended across a strait between two rocks by means of heavy wire cables. Slipping beneath these rocks and into the shadow, Bob was rejoiced to find that between the stringers and the sh.o.r.e, smaller cables had been bent to act as guy lines. If he could walk "hand over hand," the distance comprised by the width of the stream he could pa.s.s the river below the level of the bridge floor. He measured the distance with his eye. It did not look farther than the length of the gymnasium at college. He seized the cable and swung himself out over the waters.

Immediately the swift and boiling current, though twenty feet below, seemed to suck at his feet. The swirling and flashing of the water dizzied his brain with the impression of falling upstream. He had to fix his eyes on the black flooring above his head. The steel cable, too, was old and rusted and harsh. Bob's hands had not for many years grasped a rope strongly, and in that respect he found them soft. His muscles, cramped more than he had realized by the bonds of his captivity, soon began to drag and stretch. When halfway across, suspended above a ravening torrent; confronted, tired, by an effort he had needed all his fresh energies to put forth, Bob would have given a good deal to have been able to clamber aboard the bridge, risk or no risk. It was, however, a clear case of needs must. He finished the span on sheer nerve and will power; and fell thankfully on the rocks below the farther abutment. For a half minute he lay there, stretching slowly his muscles and straightening his hands, which had become cramped like claws. Then he crept, always in the shadow, to the level of the meadow.

Bob was learning to be a mountaineer. Therefore, on the way down, he had subconsciously noted that from the head of the meadow a steep dry wash climbed straight up to intersect the road. The recollection came to the surface of his mind now. If he could make his way up this wash, he would gain three advantages: he would materially shorten his journey by cutting off a mile or so of the road-grade's twists and doublings; he would avoid the necessity of showing himself so near the Cove in the bright moonlight; and he would leave no tracks where the road touched the valley. Accordingly he turned sharp to the left and began to pick his way upstream, keeping in close to the river and treading as much as possible on the water-worn rocks. The willows and elders protected him somewhat. In this manner he proceeded until he had come to the smooth rock ap.r.o.ns near the gorge from which the river flowed. Here, in accordance with his intention of keeping close in the shadow of the mountain, he was to turn to the right until he should have arrived at the steep "chimney" of the wash. He was about to leave the shelter of the last willows when he looked back. As his eyes turned, a flash of moonlight struck them full, like the heliographing of a mirror. He fixed his gaze on the bushes from which the flicker had come. In a moment it was repeated. Then, stooping low, a human figure hurried across a tiny opening, and once again the moonlight reflected from the worn and shining revolver in its hand.

XXVIII

In some manner Saleratus Bill had discovered the young man's escape, and had already eliminated the other possibilities of his direction of flight. Bob shuddered at this evidence of the rapidity with which the expert trailer had arrived at the correct conclusion. He could not now skirt the mountain, as he had intended, for that would at once expose him in full view; he could not return by the way he had come, for that would bring him face to face with his enemy. It would avail him little to surrender, for the gun-man would undoubtedly make good his threats; fidelity to such pledges is one of the few things sacred to the race.

With some vague and desperate idea of defence, Bob picked up a heavy branch of driftwood. Then, as the man drew nearer, Bob scrambled hastily over the smooth ap.r.o.n to the tiny beach that the eddies had washed out below the precipice.

Here for the moment he was hidden, but he did not flatter himself he would long remain so. He cast his eyes about him for a way of escape. To the one side was the river, in front of him was the rock ap.r.o.n with his enemy, to the other side and back of him was a sheer precipice. In his perplexity he looked down. A gleam of metal caught his eye. He stooped and picked up the half of a worn horseshoe. Even in his haste of mind, he cast a pa.s.sing wonderment on how it had come there.

If Bob had not been trained by his river work in the ways of currents, he might sooner have thought of the stream. But well he knew that Saleratus Bill had spoken right when he had said that there were "no swimming holes" here. The strongest swimmer could not have taken two strokes in that cauldron of seething white water. But now, as Bob looked, he saw that a little back eddy along the perpendicularity of the cliff slowed the current close to the sheer rock. It might be just possible, with luck, to win far enough along this cliff to lie concealed behind some outjutting boulder until Saleratus Bill had examined the beach and gone his way. Bob was too much in haste to consider the unexplained tracks he must leave on the sand.

He thrust the branch he carried into the still black water. To his surprise it hit bottom at a foot's depth. Promptly he waded in. Sounding ahead, he walked on. The underwater ledge continued. The water never came above his knees. Out of curiosity he tapped with his branch until he had reached the edge of the submerged shelf. It proved to be some four feet wide. Beyond it the water dropped off sheer, and the current nearly wrenched the staff from Bob's hand.

In this manner he proceeded cautiously for perhaps a hundred feet. Then he waded out on another beach.

He found himself in a pocket of the cliffs, where the precipice so far drew back as to leave a clear s.p.a.ce of four or five acres in the river bottom. Such pockets, or "coves," are by no means unusual in the inaccessible depths of the great box canons of the Sierras. Often the traveller can look down on them from above, lying like green gems in their settings of granite, but rarely can he descend to examine them.

Thankfully Bob darted to one side. Here for a moment he might be safe, for surely no one not driven by such desperation as his own would dream of setting foot in the river.

A loud snort almost at his elbow, and a rush of scurrying shapes, startled him almost into crying aloud. Then out into the moonlight from the shadow of the cliffs rushed two horses. And Bob, seeing what they were, sprang from his fancied security into instant action, for in a flash he saw the significance of the broken horseshoe on the beach, the sunken ledge, and the secret of the horses' pasture. By sheer chance he had blundered on one of Saleratus Bill's outlaw retreats.

Hastily he skirted the walls of the tiny valley. They were unbroken. The river swept by tortured and tumbled. He ran to the head of the cove. No sunken ledge there rewarded him. Instead, the river at that point swept inward, so that the full force of the current washed the very sh.o.r.es.

Bob searched the prospect with eager eye. Twelve or fifteen feet upstream, and six or seven feet out from the cliff, stood a huge round boulder. That alone broke the shadowy expanse of the river, which here rushed down with great velocity. Manifestly it was impossible to swim to this boulder. Bob, however, conceived a daring idea. At imminent risk and by dint of frantic scrambling he worked his way along the cliff until he had gained a point opposite the boulder and considerably above it. Then, without hesitation, he sprang as strongly as he was able sidewise from the face of the cliff.

He landed on the boulder with great force, so that for a moment he feared he must have broken some bones. Certainly his breath was all but knocked from his body. Spread out flat on the top of the rock, he moved his limbs cautiously. They seemed to work all right. He backed cautiously until he lay outspread on the upstream slope of the boulder.

At just this moment he caught the sinister figure of Saleratus Bill moving along the sunken ledge.

For the first time Bob remembered the tracks he must have left and the man's skill at trailing. A rapid review of his most recent actions rea.s.sured him at one point; in order to gain to the first of the minor cliff projections by means of which he had spread-eagled along the face of the rock, he had been forced to step into the very shallow water at the stream's edge. Thus his last footprints led directly into the river.

The value of this impression, conjoined with the existence of a ledge below over which he had already waded safely, was not lost on Bob's preception. As has been stated, his earlier experience in river driving had given him an intimate knowledge of the action of currents. Casting his eye hastily down the moonlit river, he seized his hat from his head and threw it low and skimming toward an eddy opposite him as he lay. The river s.n.a.t.c.hed it up, tossed it to one side or another, and finally carried it, as Bob had calculated, within a few feet of the ledge along which Saleratus Bill was still making his way.

The gun-man, of course, caught sight of it, and even made an attempt to capture it as it floated past, but without avail. It served, however, to prepossess his mind with the idea that Bob had been swept away by the river, so that when, after a careful examination of the tiny cove, he came to the trail leading into the water, he was prepared to believe that the young man had been carried off his feet in an attempt to wade out past the cliff. He even picked up a branch, with which he poked at the bottom. A short and narrow rock projection favoured his hypothesis, for it might very well happen that merely an experimental venture on so slanting and slippery a footing would prove fatal. Saleratus Bill examined again for footprints emerging; threw his branch into the river, and watched the direction of its course; and then, for the first time, slipped the worn and shiny old revolver into its holster. He spent several moments more reexamining the cove, glanced again at the river, and finally disappeared, wading slowly back around the sunken ledge.

Bob's next task was to regain solid land. For some minutes he sat astride the boulder, estimating the force and directions of the current.

Then he leaped. As he had calculated, the stream threw him promptly against the bank below. There his legs were immediately sucked beneath the overhanging rock that had convinced Saleratus Bill of his captive's fate. It seemed likely now to justify that conviction. Bob clung desperately, until his muscles cracked, but was unable so far to draw his legs from underneath the rock as to gain a chance to struggle out of water. Indeed, he might very well have hung in that equilibrium of forces until tired out, had not a slender, water-washed alder root offered itself to his grasp. This frail shrub, but lightly rooted, nevertheless afforded him just the extra support he required. Though he expected every instant that the additional ounces of weight he from moment to moment applied to it would tear it away, it held. Inch by inch he drew himself from the clutch of the rushing water, until at length he succeeded in getting the broad of his chest against the bank. A few vigorous kicks then extricated him.

For a moment or so he lay stretched out panting, and considering what next was to be done. There was a chance, of course--and, in view of Saleratus Bill's shrewdness, a very strong chance--that the gun-man would add to his precautions a wait and a watch at the entrance to the cove. If Bob were to wade out around the ledge, he might run fairly into his former jailer's gun. On the other hand, Saleratus Bill must be fairly well convinced of the young man's destruction, and he must be desirous of changing his wet clothes. Bob's own predicament, in this chill of night, made him attach much weight to this latter consideration. Besides, any delay in the cove meant more tracks to be noticed when the gun-man should come after the horses. Bob, his teeth chattering, resolved to take the chance of instant action.

Accordingly he waded back along the sunken ledge, glided as quickly as he could over the rock ap.r.o.n, and wormed his way through the gra.s.ses to the dry wash leading up the side of the mountains. Here fortune had favoured him, and by a very simple, natural sequence. The moon had by an hour sailed farther to the west; the wash now lay in shadow.

Bob climbed as rapidly as his wind would let him, and in that manner avoided a chill. He reached the road at a broad sheet of rock whereon his footsteps left no trace. After a moment's consideration, he decided to continue directly up the mountainside through the thick brush. This travel must be uncertain and laborious; but if he proceeded along the road, Saleratus Bill must see the traces he would indubitably leave. In the obscurity of the shady side of the mountain he found his task even more difficult than he had thought possible. Again and again he found himself puzzled by impenetrable thickets, impa.s.sable precipices, rough outcrops barring his way. By dint of patience and hard work, however, he gained the top of the mountain. At sunrise he looked back into Bright's Cove. It lay there peacefully deserted, to all appearance; but Bob, looking very closely, thought to make out smoke. The long thread of the road was quite vacant.

XXIX

Bob had no very clear idea of where he was, except that it was in the unfriendly Durham country. It seemed well to postpone all public appearances until he should be beyond a chance that Saleratus Bill might hear of him. Bob was quite satisfied that the gun-man should believe him to have been swept away by the current.
