"Good-by, Sis," he said. "I'm off for the front in ten minutes."

"Anybody hurt?" Slater asked quickly.

"Not yet, but somebody's liable to be. Gordon is trying to steal the canon, and Murray has ordered me out with a car of dynamite to hold it."

"Dynamite! Why, Dan!" his sister exclaimed in consternation.

"We have poling-boats at the lower crossing and we'll be at the canon in two days. I'm going to load the hillside with shots, and if they try to come through I'll set 'em off. They'll never dare tackle it." Dan's eyes were dancing; his face was alive with excitement.

"But suppose they should?" Eliza insisted, quietly.

"Then send Doc Gray with some stretchers. I owe one to Gordon, and this is my chance." Drawing her aside, he said in an undertone. "You've got to hold my ground with Natalie while I'm gone. Don't let her see too much of Murray."

"I'll do the best I can," she answered him, "but if he seems to be in earnest I'll renig, no matter what happens to you, Danny."

He kissed her affectionately and fled.

HOW GORDON FAILED IN HIS CUNNING

The so-called canon of the Salmon River lies just above the twin glaciers. Scenically, these are by far the more impressive, and they present a more complex engineering problem; yet the canon itself was the real strategic point in the struggle between the railroad-builders.

The floor of the valley immediately above Garfield glacier, though several miles wide, was partly filled with detritus which had been carried down from the mother range on the east, and this ma.s.s of debris had forced the stream far over against the westward rim, where it came roaring past the foot wall in a splendid cataract some three miles long. To the left of the river, looking up-stream at this point, the mountains slanted skyward like a roof, until lost in the hurrying scud four thousand feet above. To the right, however, was the old moraine, just mentioned, consisting of a desolate jumble of rock and gravel and silt overlaying the ice foot. On account of its broken character and the unstable nature of its foundation this bank was practically useless for road-building, and the only feasible route for steel rails was along the steep west wall.

O'Neil on his first reconnaissance had perceived that while there was room for more than one bridge across the Salmon between the upper and the lower ice ma.s.ses, there was not room for more than one track alongside the rapids, some miles above that point. He knew, moreover, that once he had established his t.i.tle to a right-of-way along the west rim of the cataract, it would be difficult for a rival to oust him, or to parallel his line without first crossing back to the east bank--an undertaking at once hazardous and costly. He had accordingly given Dan Appleton explicit instructions to be very careful in filing his survey, that no opportunity might be left open for a later arrival. The engineer had done his work well, and O'Neil rested secure in the belief that he held possession of the best and least expensive route through to the open valleys above. He had had no cause to fear a clash with the Heidlemann forces, for they had shown a strict regard for his rights and seemed content to devote themselves to developing their terminus before trying to negotiate the canon. They were wise in taking this course, for their success would mean that O'Neil's project would fall of its own weight. Kyak was nearer Seattle, by many miles, than Omar; it was closer to the coal and copper fields, and the proven permanence of their breakwater would render useless further attempts to finance the S. R. & N.

But in the entrance of Curtis Gordon into the field O'Neil recognized danger. Gordon was swayed by no such business scruples as the Heidlemanns; he was evidently making a desperate effort to secure a footing at any cost. In purchasing the McDermott holdings he had executed a coup of considerable importance, for he had placed himself on equal footing with the Trust and in position to profit by its efforts at harbor-building without expense to himself. If, therefore, he succeeded in wresting from O'Neil the key to that upper pa.s.sageway, he would be able to block his personal enemy and to command the consideration of his more powerful rival.

No one, not even the Trust, had taken the McDermott enterprise seriously, but with Curtis Gordon in control the "wildcat" suddenly became a tiger.

In view of all this, it was with no easy mind that O'Neil despatched Appleton to the front, and it was with no small responsibility upon his shoulders that the young engineer set out in charge of those wooden boxes of dynamite. Murray had told him frankly what hung upon his success, and Dan had vowed to hold the survey at any cost.

Steam was up and the locomotive was puffing restlessly when he returned from his farewell to Eliza. A moment later and the single flat car carrying his party and its dangerous freight was being whirled along the sh.o.r.es of Omar Lake. On it rushed, shrieking through the night, out from the gloomy hills and upon the tangent that led across the delta.

Ten minutes after it had rolled forth upon the trestle at the "lower crossing" the giant powder had been transferred to poling-boats and the long pull against the current had begun.

O'Neil had picked a crew for Dan, men upon whom he could depend. They were on double pay, and as they had worked upon the North Pa.s.s & Yukon, Appleton had no doubt of their loyalty.

The events of that trip were etched upon the engineer's mind with extraordinary vividness, for they surpa.s.sed in peril and excitement all his previous experiences. The journey resembled nothing but the mad scramble of a gold stampede. The stubborn boats with their cargoes which had to be so gently handled, the ever-increasing fury of the river, the growing menace of those ghastly, racing icebergs, the taut-hauled towing-lines, and the straining, sweating men in the loops, all made a picture hard to forget. Then, too, the uncertainty of the enterprise, the crying need of haste, the knowledge of those other men converging upon the same goal, lent a gnawing suspense to every hour.

It was infinitely more terrible than that first expedition when he and Tom Slater and O'Neil had braved the unknown. It was vastly more trying than any of the trips which had followed, even with the winter hurricane streaming out of the north as from the mouth of a giant funnel.

Dan had faced death in various forms upon this delta during the past year and a half. He had seen his flesh harden to marble whiteness under the raging north wind; his eyes and lungs had been drifted full of sand in summer storms which rivaled those of the Sahara. With transit on his back he had come face to face with the huge brown grizzly. He had slept in mud, he had made his bed on moss which ran water like a sponge; he had taken danger and hardship as they came--yet never had he punished himself as on this dash.

Through his confusion of impressions, his intense preoccupation with present dangers and future contingencies, the thought of Natalie floated now and then vaguely but comfortingly. He had seen her for a moment, before leaving--barely long enough to explain the nature of his mission--but her quick concern, her unvoiced anxiety, had been very pleasant, and he could not believe that it was altogether due to her interest in the fortunes of O'Neil.

Dan knew that Mellen's crew was camped at the upper crossing, busied in drilling for the abutments and foundations of the bridge; but he reasoned that they would scarcely suspect the object of Gordon's party and that, in any case, they were not organized or equipped to resist it. Moreover, the strategic point was four miles above the bridge site, and the surveying corps would hardly precipitate a clash, particularly since there was ample room for them to select a crossing-place alongside.

It was after midnight of the second day when he and his weary boatmen stumbled into sight of the camp. Appleton halted his command and stole forward, approaching the place through the tangled alders which flanked it. He had antic.i.p.ated that the rival party would be up to this point by now, if not even farther advanced, and he was both angered and relieved to sight the tops of other tents pitched a few hundred yards beyond Mellen's outfit. So they were here! He had arrived in time, after all! A feeling of exultation conquered the deathly fatigue that slowed his limbs. Although he still had to pa.s.s the invader's camp and establish himself at the canon, the certainty that he had made good thus far was ample reward for his effort.

A dog broke into furious barking as he emerged from cover, and he had a moment's anxiety lest it serve as warning to the enemy; but a few quick strides brought him to the tent of Mellen's foreman. Going in, he roused the man, who was sleeping soundly.

"h.e.l.lo!" cried the foreman, jumping up and rubbing his eyes, "I thought Curtis Gordon had taken possession."

"Hush! Don't wake them up," Dan cautioned.

"Oh, there's no danger of disturbing them with this infernal cannonading going on all the time." The night resounded to a rumbling crash as some huge ma.s.s of ice split off, perhaps two miles away.

"When did they arrive?"

"Night before last. They've located right alongside of us. Gee! we were surprised when they showed up. They expect to break camp in the morning." He yawned widely.

"Hm-m! They're making tracks, aren't they? Were they friendly?"

"Oh, sure! So were we. There was nothing else to do, was there? We had no orders."

"I have two dozen men and four boatloads of dynamite with me. I'm going to hold that mountainside."

"Then you're going to fight!" All vestige of drowsiness had fled from the man's face.

"Not if we can help it. Who is in charge of this crew?"

"Gordon himself."

"Gordon!"

"Yes! And he's got a tough gang with him."

"Armed?"

"Sure! This is a bear country, you know."

"Listen! I want you to tell him, as innocently as you can, that we're on the job ahead of him. Tell him we've been there for a week and have loaded that first rock shoulder and expect to shoot it off as soon as possible. You can tell him, too, that I'm up there and he'd better see me before trying to pa.s.s through."

"I've got you! But that won't stop him."

"Perhaps! Now have you any grub in camp?"

"No."

"We threw ours overboard, to make time. Send up anything you can spare; we're played out."

"It'll be nothing but beans, and they're moldy."

"We can fight on beans, and we'll eat the paper off those giant cartridges if we have to. Don't fail to warn Gordon that the hillside is mined, and warn him loud enough for his swampers to hear."
