Never had Azuma-zi seen a man killed so swiftly and pitilessly. The big humming machine had slain its victim without wavering for a second from its steady beating. It was indeed a mighty god. The unconscious scientific manager stood with his back to him, scribbling on a piece of paper. His shadow lay at the foot of the monster. Was the Lord Dynamo still hungry? His servant was ready. Azuma-zi made a stealthy step forward; then stopped. The scientific manager suddenly ceased his writing, walked down the shed to the endmost of the dynamos, and began to examine the brushes. Azuma-zi hesitated, and then slipped across noiselessly into the shadow by the switch. There he waited. Presently the manager's footsteps could be heard returning. He stopped in his old position, unconscious of the stoker crouching ten feet away from him. Then the big dynamo suddenly fizzled, and in another moment Azuma-zi had sprung out of the darkness upon him. First, the scientific manager was gripped round the body and swung towards the big dynamo, then, kicking with his knee and forcing his antagonist's head down with his hands, he loosened the grip on his waist and swung round away from the machine. Then the black grasped him again, putting a curly head against his chest, and they swayed and panted as it seemed for an age or so. Then the scientific manager was impelled to catch a black ear in his teeth and bite furiously. The black yelled hideously. They rolled over on the floor, and the black, who had apparently slipped from the vice of the teeth or parted with some ear--the scientific manager wondered which at the time--tried to throttle him. The scientific manager was making some ineffectual efforts to claw something with his hands and to kick, when the welcome sound of quick footsteps sounded on the floor. The next moment Azuma-zi had left him and darted towards the big dynamo. There was a splutter amid the roar. The officer of the company who had entered stood staring as Azuma-zi caught the naked terminals in his hands, gave one horrible convulsion, and then hung motionless from the machine, his face violently distorted. "I'm jolly glad you came in when you did," said the scientific manager, still sitting on the floor. He looked at the still quivering figure. "It is not a nice death to die, apparently--but it is quick." The official was still staring at the body. He was a man of slow apprehension. There was a pause. The scientific manager got up on his feet rather awkwardly. He ran his fingers along his collar thoughtfully, and moved his head to and fro several times. "Poor Holroyd! I see now." Then almost mechanically he went towards the switch in the shadow and turned the current into the railway circuit again. As he did so the singed body loosened its grip upon the machine and fell forward on its face. The core of the dynamo roared out loud and clear, and the armature beat the air.
