"Wind risin'—an' you figurin' on construction work!" commented McGraw.

"If she doesn't go to smash in the next half-hour, we'll be O.K.," answered Blake coolly. "That train has waited long enough. You look to the steel. Load the first sections for this end on the outermost car. We can cut it off the train at the towers."

At McGraw's nod, he scratched off an order and sent a man running with it to the waiting train. Very shortly the three outermost cars came rolling toward him, pushed by the switch crew and a gang of laborers. Their weight was several times offset by the weight of flooring material that had already been hurled from the bridge.

Blake tested the force of the wind, noted the distance that the main traveller had moved shoreward, and promptly ordered the work of destruction to cease. Some forty or fifty thousand dollars' worth of material had already gone over into the strait, and he was too much of an engineer to permit unnecessary waste.

The electro-magnetic crane of the smaller traveller was already swinging up a number of pieces of structural steel to load on the cars as they rolled out to the extreme end of the service-track. McGraw came hurrying to take charge of the eager loading gang. Blake went out past them to the end of the overhang, and perching himself on a pile of steel, began to jot down figures and small diagrams on the back of his pad.

He was still figuring when a cheer from the carloaders caused him to look up. The cars, which had been stacked with steel to their utmost capacity, were being connected with the rear of the train by means of a wire rope. In response to the signals of McGraw, the engine started slowly shoreward.

Before the train had moved many yards the slack of the steel rope was taken up. It tautened and drew up almost to a straight line, so tense that it sang like a violin string in the sharp wind gusts. Then the steel-laden cars creaked, started, and rolled shoreward after the train, groaning under their burden. The men all along the bridge raised a wild cheer.

Blake stepped back beside McGraw.

"Well, Mac, guess we've turned the trick," he said.

"Close,—huh?" replied the general foreman, holding up his hand to the wind.
