Other companies marched up and halted at the pit edge. My outfit were whites--Russians, French, Germans. But the others were black, brown, yellow--all the motley aggregation of races that formed the Red cohorts, the backbone of the Great Uprising. As the "At ease" order snapped out a babel of tongues rose on the air. Every language of Earth was there save English. The Anglo-Saxons had chosen tortured death rather than submission to the commands of their conquerors. A huge platform rose slowly up in the shaft and came to a stop at the ground level. It was solidly packed with another throng of soldiers in the gray-green of the enemy. They marched off and we took their place. * * * * * Down, down, we went, till it seemed that our destination was the center of the earth. Louder and louder grew the growling roar, the ponderous thud and clank of huge machines. We were in a huge chamber, hollowed out of the solid rock. Thousands of men bustled out among great piles of lumber and steel rails. Huge cranes rolled here and there, swinging their ponderous loads. Officers shouted crisp orders. Green-uniformed privates sprang to obey. But no time was given me to get more than a glimpse of all this activity. From out the gaping mouth of a hundred-foot-wide tunnel a long train of flat cars came gliding. It halted and swayed on the single rail, and the whir of the gyroscopic balancers filled the cavern. A sharp order, and my companions leaped for the cars, lay prone on the steel car-beds, and passed their belts through projecting loops. I wondered, but imitated them. I buried my face in my arms, as the others were doing. There came the eery shriek of a siren: the train was moving. Swiftly it gathered speed till it seemed as though my protesting body was being forced through a wall of air grown suddenly solid. Myriad fingers pulled at me, seeking to hurl me to destruction. Even through my protecting arms my breath was forced back into my lungs, choking me. The wind howled past with the wail of a thousand souls in torment. Just as the limit of endurance was reached the terrific speed slackened, and the long train ground to a halt. "All off! Lively now!" came the command. * * * * * We were at the rail-head, and before me was the face of the tunnel. Queer, hooded figures were there bending over wheeled tripods, manipulating what appeared to be searchlights. But no shafts of light leaped from the lenses. The tripods were rolling steadily forward.
