“An’ ye’re thinkin’ that’s a reason fer givin’ ye something, is it?” demanded the big foreman rather cynically, with a trace of amusement. “I thought ye said ye was shut av the sea—that ye was through now, once an’ fer all?”

“So I did, but I’ve changed me mind. It’s needin’ the work I am.”

“Very well, then,” said Cavanaugh. “We’re beginnin’ in the mornin’. See that ye’re here at seven sharp. An’ mind ye, no worryin’ or lookin’ around. We’ve a safe way now. It’s different. There’s no danger.”

McGlathery gratefully eyed his old superior, then departed, only to return the next morning a little dubious but willing. St. Columba had certainly indicated that all would be well with him—but still— A man is entitled to a few doubts even when under the protection of the best of saints. He went down with the rest of the men and began cleaning out that nearest section of the tunnel where first water and then earth had finally oozed and caked. That done he helped install the new pilot tunnel which was obviously a great improvement over the old system. It seemed decidedly safe. McGlathery attempted to explain its merits to his wife, who was greatly concerned for him, and incidentally each morning and evening on his way to and from his task he dropped in at St. Columba’s to offer up a short silent prayer. In spite of his novena and understanding with the saint he was still suspicious of this dread river above him, and of what might happen to him in spite of St. Columba. The good saint, due to some error on the part of McGlathery, might change his mind.

Nothing happened, of course, for days and weeks and months. Under Cavanaugh’s direction the work progressed swiftly, and McGlathery and he, in due time, became once more good friends, and the former an expert bracer or timberer, one of the best, and worth seven a day really, which he did not get. Incidentally, they were all shifted from day to night work, which somehow was considered more important. There were long conversations now and again between Cavanaugh and Henderson, and Cavanaugh and other officials of the company who came down to see, which enlightened McGlathery considerably as to the nature and danger of the work. Just the same, overhead was still the heavy river—he could feel it pushing at him at times, pushing at the thick layer of mud and silt above him and below which with the aid of this new pilot shield they were burrowing.

Yet nothing happened for months and months. They cleared a thousand feet without a hitch. McGlathery began to feel rather comfortable about it all. It certainly seemed reasonably safe under the new system. Every night he went down and every morning came up, as hale and healthy as ever, and every second week, on a Tuesday, a pay envelope containing the handsome sum of seventy-two dollars was handed him. Think of it! Seventy-two dollars! Naturally, as a token of gratitude to St. Columba, he contributed liberally to his Orphans’ Home, a dollar a month, say, lit a fresh candle before his shrine every Sunday morning after high mass, and bought two lots out on the Goose Creek waterfront—on time—on which some day, God willing, he proposed to build a model summer and winter cottage. And then—! Well, perhaps, as he thought afterward, it might have been due to the fact that his prosperity had made him a little more lax than he should have been, or proud, or not quite as thoughtful of the saint as was his due. At any rate, one night, in spite of St. Columba—or could it have been with his aid and consent in order to show McGlathery his power?—the wretched sneaky river did him another bad turn, a terrible turn, really.

It was this way. While they were working at midnight under the new form of bracing, based on the pilot tunnel, and with an air pressure of two thousand pounds to the square inch which had so far sufficed to support the iron roof plates which were being put in place behind the pilot tunnel day after day, as fast as space permitted, and with the concrete men following to put in a form of arch which no river weight could break, the very worst happened. For it was just at this point where the iron roof and the mud of the river bottom came in contact behind the pilot tunnel that there was a danger spot ever since the new work began. Cavanaugh had always been hovering about that, watching it, urging others to be careful—“taking no chances with it,” as he said.

“Don’t be long, men!” was his constant urge. “Up with it now! Up with it! In with the bolts! Quick, now, with yer riveter—quick! quick!”

And the men! How they worked there under the river whenever there was sufficient space to allow a new steel band to be segmentally set! For at that point it was, of course, that the river might break through. How they tugged, sweated, grunted, cursed, in this dark muddy hole, lit by a few glittering electric arcs—the latest thing in tunnel work! Stripped to the waist, in mud-soaked trousers and boots, their arms and backs and breasts mud-smeared and wet, their hair tousled, their eyes bleary—an artist’s dream of bedlam, a heavenly inferno of toil—so they labored. And overhead was the great river, Atlantic liners resting upon it, thirty or fifteen or ten feet of soil only, sometimes, between them and this thin strip of mud sustained, supposedly, by two thousand pounds of air pressure to the square inch—all they had to keep the river from bleeding water down on them and drowning them like rats!

“Up with it! Up with it! Up with it! Now the bolts! Now the riveter! That’s it! In with it, Johnny! Once more now!”
