"Must know him."
"He may change his mind," said Griffith. "The company has authorized me to make it a standing offer. So if he turns up any time—"
McGraw nodded, and offered his hand to Blake. "Hope you'll come. C'n do
m' own work. Bridge needs an engineer, though—resident one."
"H'm,—Mr. Ashton might call that a slap on the wrist," remarked
Griffith. "Get on your coat. We're going out to the bridge."
McGraw headed across for his separate room. While waiting for him, Griffith introduced Blake to the engine-driver of the bridge-service train, two or three foremen, and several of the bridge workers. But the moment McGraw reappeared in arctics and Mackinaw coat, Griffith hurriedly led the way out of the smother of smoke and foul air.
As the three started bridgeward along the clean-shovelled service-track Blake fell in behind his companions. Seeing that he did not wish to talk, Griffith walked on in the lead with McGraw.
They were soon swinging out across the shore, or approach, span of the bridge. This extended from the high ground on the south side of the strait to an inner pier at the edge of the water, where it joined on to the anchor arm of the south cantilever. Almost all the area of the bridge flooring, which had been completed to beyond the centre of the cantilever, was covered with stacked lumber and piles of structural steel and rails, and kegs of nails, rivets, and bolts.
Here every chink and crevice was packed with snow and ice. But all the titanic steel structure above and the unfloored bottom-chords and girders of the outer, or extension, arm of the cantilever had been swept bare of snow by the winter gales and left glistening with the glaze of the last shower of sleet.
Blake swung steadily along after the others, his face impassive. But his eyes scrutinized with fierce eagerness the immense webs of steel posts and diagonals that ran up on either side, under the grand vertical curves of the top-chords, almost to the peaks of the cantilever towers. He had to tilt back his head to see the tops of those huge steel columns, which reared their peaks two hundred and fifty feet above the bridge-floor level and a round four hundred feet above the water of the strait.
Presently the three were passing the centre of the cantilever, between the gigantic towers, whose iron heels were socketed far below in the top-plates of the massive concrete piers, built on the very edge of deep water. From this point the outer arm of the cantilever extended far out over the broad chasm of the strait, where, a hundred and fifty feet beneath its unfloored level, the broken ice from the upper lake crashed and thundered on its wild passage of the strait.
Blake looked down carelessly into the abyss of grinding, hurtling ice cakes. The drop from that dizzy height would of itself have meant certain death. Yet without a second glance at the ice-covered waters, he followed his companions along the narrow walk of sleeted planks that ran out alongside the service-track. Though his gaze frequently shifted downward as well as upward, it went no farther than the ponderous chords and girders and posts of the bridge's framework.
