He did not answer. His eyes were fixed on the steam gauge, his lips close shut.
"More coal," he said.
I threw it in. The fields and houses began to fly past half-seen. We were nearing Dufreme, the next station. Markley's eyes went from the gauge to the face of the timepiece and back. He moved like an automaton. There was little more meaning in his face.
"More!" he said, without turning his eye.
"Markley, do you know you are going at the rate of sixty miles an hour?"
"Coal!"
I was alarmed at the stern, cold rigidity of the man. His pallor was becoming frightful. I threw in the coal. At least we must stop at Dufreme. That was the next halt. The little town was approaching. As the first house came into view the engine sent its shrieks of warning; it grew louder—still louder.
We dashed over the switches, up to the station, where a group of passengers waited, and passed it without the halt of an instant, catching a glimpse of the appalled faces and the waiting crowd. Then we were in the fields again. The speed now became literally breathless, the furnace glared red hot. The heat, the velocity, the terrible nervous strain of the man beside me seemed to weight the air. I found myself drawing long, stertorous breaths, like one drowning.
I heaped in the coal at intervals as he bade me. I did it because I was oppressed by an odd sense of duty which I never had in my ordinary brainwork. Since then I have understood how it is that dull, ignorant men, without a spark of enthusiasm, show such heroism as soldiers, firemen, and captains of wrecked vessels.
