“Don’t be a fool!” Jeremy ejaculated. “If there really is trouble these streets won’t be too pleasant, and we’d better not draw attention to ourselves.” Immediately in the rear of his words came the confused noise of many people running and shouting. It was the mixed population of Whitechapel going to see what was up; and before many of them could have done so, the real fighting must have begun. The sound of firing, scattered and spasmodic, punctuated by the dull, vibrating bursts which Jeremy recognized for bombs, came abruptly to the listeners in the warehouse. There was an opening and shutting of windows and a banging of doors, men shouting and women crying, as though suddenly the whole district had been set in motion. All this gradually died away again and left to come sharper and clearer the incessant noise of the rifles and the bombs.

“Scott has set them going,” Jeremy murmured to himself, almost content in the fulfilment of a prophecy, and then he said aloud: “Have you got any cigarettes, Augustus? I can’t say we’re well off where we are, but we’ve got to stop for a bit.”

Trehanoc produced a tin of Virginians which he offered to his guests. “I’m afraid,” he said miserably, “that this isn’t a very good time for asking you to have a look at my experiment.” Jeremy surveyed him with a curious eye, and reflected that the contrast in the effect of the distant firing on the three of them was worth observation. He himself did not pretend to like it, but knew that nothing could be done, and so endured it stoically. MacIan had settled in an armchair with a cigarette and a very tattered copy of La Vie Parisienne, and was giving an exhibition of almost flippant unconcern; but every time there was a louder burst of fire his shoulders twitched slightly. Trehanoc’s behavior was the most interesting of all. He had been nervous and excited while they were at table, and the explosion had obviously accentuated his condition. But he had somehow turned his excitement into the channel of his discovery, and his look of hungry and strained disappointment was pathetic to witness. It touched Jeremy’s heart, and moved him to say as heartily as he could:

“Nonsense, old fellow. We’ll come along and see it in a moment. What’s it all about?”

Trehanoc murmured “Thanks awfully.... I was afraid you wouldn’t want....”—like a child who has feared that the party would not take place after all. Then he sat down sprawlingly in a chair and fixed his wild, shining eyes on Jeremy’s face. “You see,” he began, “I think it’s a new ray. I’m almost certain it’s a new ray. But I’m not quite certain how I got it. I’ll show you all that later. But it’s something like the ray that man used to change bacilli. He changed bacilli into cocci, or something. I’m no biologist; I was going to get in a biologist when you’d helped me a bit. You remember the experiment I mean, don’t you?”

“Vaguely,” said Jeremy. “It’s a bit out of my line, but my recollection is that he used alpha rays. However, go on.”

“Well, that’s what I was after,” Trehanoc continued. “I believe these rays do something of the same kind, and they’ve got other properties I don’t understand. There’s the rat ... but I’ll show you the rat later on. And then I got my hand in front of the vacuum-tube for half a second without any protection....”

“Did you get a burn?” Jeremy asked sharply.

“No,” said Trehanoc. “No ... I didn’t ... that’s the strange thing. I’d got a little radium burn on that hand already, and a festering cut as well, where I jabbed myself with the tin-opener.... Well, first of all, my hand went queer. It was a sort of dead, numb feeling, spreading into the arm above the wrist, and I was scared, I can tell you. I was almost certain that these were new rays, and I hadn’t the least notion what effect they might have on living tissue. The numbness kept on all day, with a sort of tingling in the finger-tips, and I went to bed in a bit of a panic. And when I woke, the radium burn had quite gone, leaving a little scar behind, and the cut had begun to heal. It was very nearly healed!”

“Quite sure it’s a new ray?” Jeremy interjected.
