She was choked with anxiety. It seemed to her that if the powder house were fired there would be no food anywhere in Soot City. Who would be killed and how much would be damaged was an unanswerable question that weakened her with painful suspense. She barely noticed the hissing rush of her breath or felt the pain in her side. Her feet grew heavy, and the noise of their fall on the road-bed sounded to her as if it was far off in the town. Her neck was craned in the direction of the plant, and she wanted to throw herself along the earth. When the lights at the sidings and at the station grew nearer her dimmed eyes could barely distinguish them. Some warm thing, with a new taste, crept over her lips. She put up her hand to it, and saw in the light at the first siding that it was blood.

Her body rocked with the push of her heart-beats, and “yet,” she thought, “I may be late.”

At last she passed the station. Through its blindless windows she could see Benz, the furnace-tender, talking fast to the police. For a moment she thought of going in and telling her story, but she feared a loss of time, and started furiously up the grade to the tool-house. She found the door standing open and entered boldly, snatching the crook and striking at a man who raised himself from the floor. He lay down again at once, saying, “All right, only don’t tell me where you put it.”

“I’m in time,” she thought.

There was a little patch of light before the threshold. Looking up, she saw four policemen crossing by the powder house to the factory. Then the scheme came entire into her puzzled brain. They were called out on search and it was their lights in the factory that were to be taken as the signal for Quarry’s men to fire the mine. The furnace-tenders had gone as guides, and the unshifted cinder could not expose offenders.

“He’s a cute viper!” Emma was talking to herself to keep her nerve; she was spent and breathless.

The heat by the furnace was terrible; it shone on the iron trough in an outlined square of yellow, where the light streamed through the door cracks. She fitted the crook’s hook to the loop of the skewer and paused, waiting. Her thoughts were busy with the way in which they might fire the powder stores. Heat and cold hurried through her alternately; her hands and brow were wet. There were, of course, no men on duty at the plant save forty of the factory force, Quarry among them. Emma saw that this was part of the blind.

The electric lights were out; they had not been turned on since early the last evening, but presently one shone from the ground floor of the factory. Emma pulled back her crook exultingly, but the skewer would not give. She jerked, but it was firm. Gathering her strength, she braced her feet and threw herself back. She saw a fiery line pass above her head, and heard the red-hot skewer tinkle against a stone behind her. She rushed to the front of the furnace to get rid of the heat, and stood on the crest of the incline.

As the cinder flew in a glowing mass down the trough to the cinder hill, she saw the spires at the city and the Bridge. Then she looked directly before her.

As the night lifted from the plant yard she saw that some one was running; the figure took on it the red of the brightening furnace waste, and the flame of the torch the runner carried grew white in the rosy glare. The light spread higher, and Emma saw the tops of the elm trees that grew on the other side of the factory. The cinder rattled in the trough with a grating loudness.
