"Call it done," said the trainmaster, and he went to carry out the order. Two minutes later Bogard, the night-relief operator off duty, darted out of the despatcher's room with the clearance-cards for the three sections. Lidgerwood stopped him in mid-flight. "One second, Robert: when you have done your errand, come back to the president's car, ask for Miss Brewster, and say that I sent you. Then stay within call and be ready to do whatever she wants you to do." Bogard did the first part of his errand swiftly, and he was taking the duplicate signatures of the engineer and conductor of the third and last section when Benson came up to put the solid-train order into effect. The couplings were made deftly and without unnecessary stir. Then Benson stepped back and gave the starting signal, twirling his lantern in rapid circles. Synchronized as perfectly as if a single throttle-lever controlled them all, the three heavy freight-pullers hissed, strained, belched fire, and the long train began to move out. It was Lidgerwood's challenge to the outlaws, and as if the blasts of the three tearing exhausts had been the signal it was awaiting, the strike storm broke with the suddenness and fury of a tropical hurricane. From a hundred hiding-places in the car-strewn yard, men came running, some to swarm thickly upon the moving engines and cabooses, others swinging by the drawheads to cut the air-brake hose. Benson was swept aside and overpowered before he could strike a blow. Bogard, speeding across to take his post beside the _Nadia_, was struck down before he could get clear of the pouring hornet swarm. Shots were fired; shrill yells arose. Into the midst of the clamor the great siren whistle at the shops boomed out the fire alarm, and almost at the the same instant a red glow, capped by a rolling nimbus of sooty oil smoke, rose to beacon the destruction already begun in the shop yards. And while the roar of the siren was still jarring upon the windless night air, the electric-light circuits were cut out, leaving the yards and the Crow's Nest in darkness, and the frantic battle for the trains to be lighted only by the moon and the lurid glow of destruction spreading slowly under its black canopy of smoke. In the Crow's Nest the sudden coup of the strikers had the effect which its originator had doubtless counted upon. It was some minutes after the lights were cut off, and the irruption had swept past the captured and disabled trains to the shops, before Lidgerwood could get his small garrison together and send it, with McCloskey for its leader, to reinforce the shop guard, which was presumably fighting desperately for the control of the power plant and the fire pumps.
