been earlier in the evening. After all, from the mechanical point of view,
it had been a most insignificant incident--the mere temporary deflection
of a current. But now the slender form and slender shadow of the
scientific manager replaced the sturdy outline of Holroyd travelling up
and down the lane of light upon the vibrating floor under the straps
between the engines and the dynamos.

"Have I not served my Lord?" said Azuma-zi inaudibly, from his shadow, and
the note of the great dynamo rang out full and clear. As he looked at the
big whirling mechanism the strange fascination of it that had been a
little in abeyance since Holroyd's death resumed its sway.

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.
