Then, the next time Holroyd maltreated him, Azuma-zi went presently to the Lord of the Dynamos and whispered, “Thou seest, O my Lord!” and the angry whirr of the machinery seemed to answer him.  Thereafter it appeared to him that whenever Holroyd came into the shed a different note came into the sounds of the dynamo.  “My Lord bides his time,” said Azuma-zi to himself.  “The iniquity of the fool is not yet ripe.”  And he waited and watched for the day of reckoning.  One day there was evidence of short circuiting, and Holroyd, making an unwary examination—­it was in the afternoon—­got a rather severe shock.  Azuma-zi from behind the engine saw him jump off and curse at the peccant coil.

“He is warned,” said Azuma-zi to himself.  “Surely my Lord is very patient.”

Holroyd had at first initiated his “nigger” into such elementary conceptions of the dynamo’s working as would enable him to take temporary charge of the shed in his absence.  But when he noticed the manner in which Azuma-zi hung about the monster he became suspicious.  He dimly perceived his assistant was “up to something,” and connecting him with the anointing of the coils with oil that had rotted the varnish in one place, he issued an edict, shouted above the confusion of the machinery, “Don’t ’ee go nigh that big dynamo any more, Pooh-bah, or a’ll take thy skin off!” Besides, if it pleased Azuma-zi to be near the big machine, it was plain sense and decency to keep him away from it.

Azuma-zi obeyed at the time, but later he was caught bowing before the Lord of the Dynamos.  At which Holroyd twisted his arm and kicked him as he turned to go away.  As Azuma-zi presently stood behind the engine and glared at the back of the hated Holroyd, the noises of the machinery took a new rhythm, and sounded like four words in his native tongue.

It is hard to say exactly what madness is.  I fancy Azuma-zi was mad.  The incessant din and whirl of the dynamo shed may have churned up his little store of knowledge and big store of superstitious fancy, at last, into something akin to frenzy.  At any rate, when the idea of making Holroyd a sacrifice to the Dynamo Fetich was thus suggested to him, it filled him with a strange tumult of exultant emotion.

That night the two men and their black shadows were alone in the shed together.  The shed was lit with one big arc light that winked and flickered purple.  The shadows lay black behind the dynamos, the ball governors of the engines whirled from light to darkness, and their pistons beat loud and steady.  The world outside seen through the open end of the shed seemed incredibly dim and remote.  It seemed absolutely silent, too, since the riot of the machinery drowned every external sound.  Far away was the black fence of the yard with grey shadowy houses behind, and above was the deep blue sky and the pale little stars.  Azuma-zi suddenly walked across the centre of the shed above which the leather bands were running, and went into the shadow by the big dynamo.  Holroyd heard a click, and the spin of the armature changed.
