King Coal by Upton Sinclair

There was one member of this committee whom Hal watched with especial anxiety -- Mary Burke. She had not yet said a word; while the others argued and protested, she sat with her lips set and her hands clenched. Hal knew what rage this failure must bring to her. She had risen and struggled and hoped, and the result was what she had always said it would be -- nothing! Now he saw her, with eyes large and dark with fatigue, fixed on this fiery young labour-leader. He knew that a war must be going on within her. Would she drop out entirely now? It was the test of her character -- as it was the test of the characters of all of them.

"If only we're strong enough and brave enough," Jim Moylan was saying, "we can use our defeats to educate our people and bring them together. Right now, if we can make the men at North Valley see what we're doing, they won't go back beaten, they won't be bitter against the union, they'll only go back to wait. And ain't that a way to beat the bosses -- to hold our jobs, and keep the union alive, till we've got into all the camps, and can strike and win?"
