I used to be the leading practitioner of Los Amigos. Of course, everyone has heard of the great electrical generating gear there. The town is wide spread, and there are dozens of little townlets and villages all round, which receive their supply from the same centre, so that the works are on a very large scale. The Los Amigos folk say that they are the largest upon earth, but then we claim that for everything in Los Amigos except the gaol and the death-rate. Those are said to be the smallest.

Now, with so fine an electrical supply, it seemed to be a sinful waste of hemp that the Los Amigos criminals should perish in the old-fashioned manner. And then came the news of the eleotrocutions in the East, and how the results had not after all been so instantaneous as had been hoped. The Western Engineers raised their eyebrows when they read of the puny shocks by which these men had perished, and they vowed in Los Amigos that when an irreclaimable came their way he should be dealt handsomely by, and have the run of all the big dynamos. There should be no reserve, said the engineers, but he should have all that they had got. And what the result of that would be none could predict, save that it must be absolutely blasting and deadly. Never before had a man been so charged with electricity as they would charge him. He was to be smitten by the essence of ten thunderbolts. Some prophesied combustion, and some disintegration and disappearance. They were waiting eagerly to settle the question by actual demonstration, and it was just at that moment that Duncan Warner came that way.

Warner had been wanted by the law, and by nobody else, for many years. Desperado, murderer, train robber and road agent, he was a man beyond the pale of human pity. He had deserved a dozen deaths, and the Los Amigos folk grudged him so gaudy a one as that. He seemed to feel himself to be unworthy of it, for he made two frenzied attempts at escape. He was a powerful, muscular man, with a lion head, tangled black locks, and a sweeping beard which covered his broad chest. When he was tried, there was no finer head in all the crowded court. It’s no new thing to find the best face looking from the dock. But his good looks could not balance his bad deeds. His advocate did all he knew, but the cards lay against him, and Duncan Warner was handed over to the mercy of the big Los Amigos dynamos.

I was there at the committee meeting when the matter was discussed. The town council had chosen four experts to look after the arrangements. Three of them were admirable. There was Joseph M’Conner, the very man who had designed the dynamos, and there was Joshua Westmacott, the chairman of the Los Amigos Electrical Supply Company, Limited. Then there was myself as the chief medical man, and lastly an old German of the name of Peter Stulpnagel. The Germans were a strong body at Los Amigos, and they all voted for their man. That was how he got on the committee. It was said that he had been a wonderful electrician at home, and he was eternally working with wires and insulators and Leyden jars; but, as he never seemed to get any further, or to have any results worth publishing he came at last to be regarded as a harmless crank, who had made science his hobby. We three practical men smiled when we heard that he had been elected as our colleague, and at the meeting we fixed it all up very nicely among ourselves without much thought of the old fellow who sat with his ears scooped forward in his hands, for he was a trifle hard of hearing, taking no more part in the proceedings than the gentlemen of the press who scribbled their notes on the back benches.

We did not take long to settle it all. In New York a strength of some two thousand volts had been used, and death had not been instantaneous. Evidently their shock had been too weak. Los Amigos should not fall into that error. The charge should be six times greater, and therefore, of course, it would be six times more effective. Nothing could possibly be more logical. The whole concentrated force of the great dynamos should be employed on Duncan Warner.

So we three settled it, and had already risen to break up the meeting, when our silent companion opened his month for the first time.

“Gentlemen,” said he, “you appear to me to show an extraordinary ignorance upon the subject of electricity. You have not mastered the first principles of its actions upon a human being.”

The committee was about to break into an angry reply to this brusque comment, but the chairman of the Electrical Company tapped his forehead to claim its indulgence for the crankiness of the speaker.

“Pray tell us, sir,” said he, with an ironical smile, “what is there in our conclusions with which you find fault?”

“With your assumption that a large dose of electricity will merely increase the effect of a small dose. Do you not think it possible that it might have an entirely different result? Do you know anything, by actual experiment, of the effect of such powerful shocks?”

“We know it by analogy,” said the chairman, pompously. “All drugs increase their effect when they increase their dose; for example—for example——”

“Whisky,” said Joseph M’Connor.

“Quite so. Whisky. You see it there.”

Peter Stulpnagel smiled and shook his head.

“Your argument is not very good,” said he. “When I used to take whisky, I used to find that one glass would excite me, but that six would send me to sleep, which is just the opposite. Now, suppose that electricity were to act in just the opposite way also, what then?”

We three practical men burst out laughing. We had known that our colleague was queer, but we never had thought that he would be as queer as this.

“What then?” repeated Philip Stulpnagel.

“We’ll take our chances,” said the chairman.

“Pray consider,” said Peter, “that workmen who have touched the wires, and who have received shocks of only a few hundred volts, have died instantly. The fact is well known. And yet when a much greater force was used upon a criminal at New York, the man struggled for some little time. Do you not clearly see that the smaller dose is the more deadly?”

“I think, gentlemen, that this discussion has been carried on quite long enough,” said the chairman, rising again. “The point, I take it, has already been decided by the majority of the committee, and Duncan Warner shall be electrocuted on Tuesday by the full strength of the Los Amigos dynamos. Is it not so?”

“I agree,” said Joseph M’Connor.

“I agree,” said I.

“And I protest,” said Peter Stulpnagel.

“Then the motion is carried, and your protest will be duly entered in the minutes,” said the chairman, and so the sitting was dissolved.

The attendance at the electrocution was a very small one. We four members of the committee were, of course, present with the executioner, who was to act under their orders. The others were the United States Marshal, the governor of the gaol, the chaplain, and three members of the press. The room was a small brick chamber, forming an outhouse to the Central Electrical station. It had been used as a laundry, and had an oven and copper at one side, but no other furniture save a single chair for the condemned man. A metal plate for his feet was placed in front of it, to which ran a thick, insulated wire. Above, another wire depended from the ceiling, which could be connected with a small metallic rod projecting from a cap which was to be placed upon his head. When this connection was established Duncan Warner’s hour was come.

There was a solemn hush as we waited for the coming of the prisoner. The practical engineers looked a little pale, and fidgeted nervously with the wires. Even the hardened Marshal was ill at ease, for a mere hanging was one thing, and this blasting of flesh and blood a very different one. As to the pressmen, their faces were whiter than the sheets which lay before them. The only man who appeared to feel none of the influence of these preparations was the little German crank, who strolled from one to the other with a smile on his lips and mischief in ............
