The brake-rider had paid for his ride, though not in money. He limped as he walked off, and the gray pallor of his unshaven face was grotesquely shaded and blotched with coal dust. His shoddy clothes were torn and mud-stained, his soft hat begrimed and shapeless, his cheap shoes too far gone for repair. Yet for all his shiftless footwear and his limp, his stride was long and quick.
A watchman caught sight of him, and hurried after, to warn him off the grounds. The hobo disappeared behind a pile of girders. When the watchman turned the corner, his quarry had disappeared. He shook his head doubtfully at the bridge-service train, which was backing out along the track before him with a load of eyebars and girders. There was reason to believe that the hobo had boarded it; but if so, it was under too speedy headway for the rheumatic watchman to follow.
His suspicions were well founded. As the train clattered past the unlovely buildings of rough lumber and sheet iron clustered about the bridge terminus, the stranger clambered up between two of the swaying cars and perched himself upon the wheel-like top of the handbrake. Seated thus, with feet dangling and hands thrust carelessly into the pockets of his disreputable coat, he gazed intently about at the bridge, regardless of the bitter sting of the lake wind.
The train rattled out across the shore span and along the anchor arm of the south cantilever. The brake-rider scrutinized the immense webs and lofty towers with the look of a father greeting his first-born. The train rolled on out between the towers and beyond, where swarms of carpenters and laborers were laying beams and stringers and floor planking and piling up immense stacks of material to be used farther out. The finishing gangs were following up the steel workers as fast as they could be pushed.
Beyond them, out near the end of the extension-arm, the electro-magnetic cranes of the huge main traveller were sorting and shifting forward a great heap of structural steel. The material thus handled came within the reach of the smaller traveller, which crouched upon the top-chords like a skeleton spider, swinging out the steel as wanted to the end of the unfinished suspension span.
At sight of the great heaps of structural steel and flooring material and of the ponderous main traveller so far out toward the end of the overhang, the glow in the sunken eyes of the brake-rider died out, and his grimy brows gathered in a troubled frown.
The airbrakes hissed, the cars bumped and clanked, and the train came to a laborious stop with the outermost cars beneath the lofty latticed framework of the main traveller. At once the electro-magnetic cranes began to descend, ready to swing off whole carloads of steel in their magic monstrous clutch.
The brake-rider had slipped down and was walking rapidly outward along the narrow plank footway. As he advanced he looked about him with an anxious gaze, but it was at the unfloored substructure of the bridge, not at the awesome spectacle of the swift-flowing, ice-covered stream a hundred and fifty feet beneath. Once he paused and stooped over to look closer at a rivet head.
He hurried on to where, under the smaller traveller, the uncompleted south part of the central, or suspension, span poised dizzily in space, over-arching the abyss. Many yards of gap still yawned between its tip and the tip of the sections that strained out to meet it from the end of the north cantilever.
The sections built on to the southern part of the central span had brought the overhang still more dizzily out over the broad strait. The wonder was that men could be found who were willing to work day after day in a position of such real peril. Yet since Ashton's change of attitude, McGraw had experienced no difficulty in securing and holding enough and to spare of expert bridge-workers, who toiled and sweat at their task with seemingly never a thought of the abyss that yawned beneath them.
