They passed banks of gigantic blast furnaces, the heart of the Homestead Steel Works, which spread over hundreds of acres on both sides of a bend in the river.

“Fort Frick,” Mary said, bitterly. “That’s what the workers called it. Frick built a fence around it to shield his Pinkerton gunmen. We shot it out with the detectives. Dozens were killed. The governor sent militia with Gatling guns. They arrested the entire Strike Committee. Thank God, juries refused to convict. But they broke the union.”

Isaac Bell did know of the Homestead Battle. The whole nation did. Henry Clay Frick, Andrew Carnegie’s manager of the Homestead Steel Works, had fought the strikers to a standstill in a long-ago war when Bell was a schoolboy. Mary must have been in school then, too. But she told it as if she had witnessed it yesterday.

“Since then, they’ve kicked the union out of every steel mill in Pennsylvania.”

They rolled past the Homestead Works. The yards would be coming up soon. Bell said, “We’ve got to jump before the yard to avoid the rail dicks. Soon as the engineer slows down. Stick close. They won’t go easy on you just because you’re a woman.”

Mary didn’t hear him. “Look at that,” she said, gesturing at a huge white sign so new it was not yet stained by soot.

AMALGAMATED COAL TERMINAL

From his research, Bell recognized the giant tipple that loomed over a combined train yard and barge wharf on a point of land that jutted into the river. It was the latest innovation in the transport of coal to market. Mechanical conveyers lifted coal from wooden Monongahela barges up to the tipple. The tipple rained it down in two directions, filling hundred-car trains, headed east to the seaboard cities, and big, modern barges that were steel-reinforced against the western-river rigors of the Ohio and the Mississippi.

Mary was exasperated by its name. “‘Amalgamated’? Why can’t they just call a combine a combine?”

Bell grinned. “Would you settle for ‘united’?”

She did not return his grin. But he saw some smile in her eyes when she fired back, “If you’ll settle for ‘monopoly.’”

“Shake on it?” They touched fingertips and stood looking at each other, balanced against the motion of the train, until Bell swept Mary into his arms and kissed her on the mouth.

At length, Mary asked, “Weren’t we supposed to jump?”

They were still rolling too fast to jump, and Bell finally realized that since it was running empty, the freight did not have to slow until shortly before it stopped.

When the air brakes finally hissed, they were in the yard, an enormous sprawl of track in every direction. It was securely fenced. Bell spotted a break in the palings down by the river twenty tracks away.

“Ready?”

“Ready.”

Bell jumped first and landed with a jolt that seared his ribs. He kept his feet and reached for Mary and caught her as she tripped.

“Let’s go. We’ll get out of here fast as we can.”
