"But why?" exclaimed the Kaiser, pulling a Mauser repeating pistol out of his hip-pocket. "Who are you, that you should give orders to me?"
"Only a man, your Majesty," replied Castellan, with a bow and a smile; "a man who could explode every cartridge in that pistol of yours at once before you had time to fire a shot. You have seen what has happened already."
William the Second had seen enough. He walked to one of the windows opening on the enclosed gardens, threw it open, dropped the pistol out, and said:
"Now, let us have the proof of what you say."
"In a moment, your Majesty," replied Castellan, going back to his machine, and beginning to work the keys rapidly. "I am here, an unarmed man; let their Excellencies, the Chancellor and the Field Marshal, attack me with their swords if they can. I am not joking. I am staking my life on the success or failure of this experiment."
"Does your Majesty consent?" said the Field Marshal, raising his sword.
"There could be no better test," replied the Kaiser. "Mr Castellan makes an experiment on which he stakes his life; we are making an experiment on which we stake the welfare of the German Empire, and, perhaps, the fate of the world. If he is willing, I am."
"And I am ready," replied Castellan, working the keys faster and faster as he spoke, and looking at the two swords as carelessly as if they had been a couple of walking sticks.
The sword points advanced towards him; the keys of the machine clicked faster and faster. The atmosphere of the room became tenser and tenser; the Kaiser leaned back against the door with his arms folded. When the points were within three feet of Castellan's head, the steel began to gleam with a bluish green light. The Chancellor and the Field Marshal stopped; they saw sparkles of blue flame running along the sword blades. Then came paralysis! the swords dropped from their hands, and they staggered back.
"Great God, this is too much," gasped the Chancellor. "The man is impregnable. It is too much, your Majesty. I fought through the war of '70 and '71, but I surrender to this; this is not human."
