Full power, please, for another twelve seconds.’

The firmament, as far as eye could reach, stood on pillars of white fire. One fell on the glowing square at Chicago, and turned it black.

‘Oh! Oh! Oh! Can men be allowed to do such things?’ Dragomiroff cried, and fell across our knees.

‘Glass of water, please,’ said Takahira to a helmeted shape that leaped forward. ‘He is a little faint.’

The lights switched off, and the darkness stunned like an avalanche. We could hear Dragomiroff’s teeth on the glass edge.

Pirolo was comforting him.

‘All right, all ra-ight,’ he repeated. ‘Come and lie down. Come below and take off your mask. I give you my word, old friend, it is all right. They are my siege-lights. Little Victor Pirolo’s leetle lights. You know me! I do not hurt people.’

‘Pardon!’ Dragomiroff moaned. ‘I have never seen Death. I have never seen the Board take action. Shall we go down and burn them alive, or is that already done?’

‘Oh, hush,’ said Pirolo, and I think he rocked him in his arms.

‘Do we repeat, sir?’ Arnott asked De Forest.

‘Give ’em a minute’s break,’ De Forest replied. ‘They may need it.’

We waited a minute, and then MacDonough’s Song, broken but defiant, rose from undefeated Chicago.

‘They seem fond of that tune,’ said De Forest. ‘I should let ’em have it, Arnott.’

‘Very good, sir,’ said Arnott, and felt his way to the Communicator keys.

No lights broke forth, but the hollow of the skies made herself the mouth for one note that touched the raw fibre of the brain. Men hear such sounds in delirium, advancing like tides from horizons beyond the ruled foreshores of space.

‘That’s our pitch-pipe,’ said Arnott. ‘We may be a bit ragged. I’ve never conducted two hundred and fifty performers before.’ He pulled out the couplers, and struck a full chord on the Service Communicators.

The beams of light leaped down again, and danced, solemnly and awfully, a stilt-dance, sweeping thirty or forty miles left and right at each stiff-legged kick, while the darkness delivered itself—there is no scale to measure against that utterance—of the tune to which they kept time. Certain notes—one learnt to expect them with terror—cut through one’s marrow, but, after three minutes, thought and emotion passed in indescribable agony.

We saw, we heard, but I think we were in some sort swooning. The two hundred and fifty beams shifted, re-formed, straddled and split, narrowed, widened, rippled in ribbons, broke into a thousand white-hot parallel lines, melted and revolved in interwoven rings like old-fashioned engine-turning, flung up to the zenith, made as if to descend and renew the torment, halted at the last instant, twizzled insanely round the horizon, and vanished, to bring back for the hundredth time darkness more shattering than their instantly renewed light over all Illinois. Then the tune and lights ceased together, and we heard one single devastating wail that shook all the horizon as a rubbed wet finger shakes the rim of a bowl.

‘Ah, that is my new siren,’ said Pirolo. ‘You can break an iceberg in half, if you find the proper pitch. They will whistle by squadrons now. It is the wind through pierced shutters in the bows.’

I had collapsed beside Dragomiroff, broken and snivelling feebly, because I had been delivered before my time to all the terrors of Judgment Day, and the Archangels of the Resurrection were hailing me naked across the Universe to the sound of the music of the spheres.

Then I saw De Forest smacking Arnott’s helmet with his open hand. The wailing died down in a long shriek as a black shadow swooped past us, and returned to her place above the lower clouds.

‘I hate to interrupt a specialist when he’s enjoying himself,’ said De Forest. ‘But, as a matter of fact, all Illinois has been asking us to stop for these last fifteen seconds.’

‘What a pity.’ Arnott slipped off his mask. ‘I wanted you to hear us really hum. Our lower C can lift street-paving.’

‘It is Hell—Hell!’ cried Dragomiroff, and sobbed aloud.

Arnott looked away as he answered:

‘It’s a few thousand volts ahead of the old shoot-’em-and-sink-’em game, but I should scarcely call it that. What shall I tell the Fleet, sir?’

‘Tell ’em we’re very pleased and impressed. I don’t think they need wait on any longer. There isn’t a spark left down there.’ De Forest pointed. ‘They’ll be deaf and blind.’

‘Oh, I think not, sir.
