When the Friday night of meeting arrived the large hall in Clement’s Inn was filled to the doors. Those assembled there saw a platform at one end of the apartment, and a door that led from it to a room at the back of the hall. A table was on the platform, and boxes, chemical apparatus, and other scientific-looking paraphernalia were on it. At the hour of eight young Simkins appeared before the table alone.

“Fellow Anarchists,” he said, “you are well aware that I am tired of the great amount of talk we indulge in, and the little action which follows it. I have been fortunate enough to secure the co-operation of an Anarchist from America, who will tell you something of the cause there. We have had the doors locked, and those who keep the keys are now down at the entrance of the Inn, so that if a fire should occur, they can quickly come and let us out. There is no great danger of fire, however, but the interruption of the police must be guarded against very carefully. The windows, as you see, are shuttered and barred, and no ray of light can penetrate from this room outside. Until the lecture is over no one can leave the room, and by the same token no one can enter it, which is more to the purpose.

“My friend, Professor Josiah P. Slivers, has devoted his life to the Chemistry of Anarchy, which is the title of this lecture. He will tell you of some important discoveries, which are now to be made known for the first time. I regret to say that the Professor is not in a very good state of health, because the line of life which he has adopted has its drawbacks. His left eye has been blown away by a premature explosion during his experiments. His right leg is also permanently disabled. His left arm, as you will notice, is in a sling, having been injured by a little disaster in his workshop since he came to London. He is a man, as you will see, devoted body and soul to the cause, so I hope you will listen to him attentively. I regret that I am unable to remain with you to-night, having other duties to perform which are imperative. I will therefore, if you will permit me, leave by the back entrance after I have introduced the Professor to you.”

At this moment the stumping of a wooden leg was heard, and those in the audience saw appear a man on crutches, with one arm in a sling and a bandage over an eye, although he beamed upon them benevolently with the other.

“Fellow Anarchists,” said Simkins, “allow me to introduce to you Professor Josiah P. Slivers, of the United States.”

The Professor bowed and the audience applauded. As soon as the applause began the Professor held up his unmaimed arm and said, “Gentlemen, I beg that you will not applaud.”

It seems the fashion in America to address a11 sorts and conditions of men as “Gentlemen.”

The Professor continued, “I have here some explosives so sensitive that the slightest vibration will cause them to go off, and I therefore ask you to listen in silence to what I have to say. I must particularly ask you also not to stamp on the floor.”

Before these remarks were concluded Simkins had slipped out by the back entrance, and somehow his desertion seemed to have a depressing effect upon the company, who looked upon the broken-up Professor with eyes of wonder and apprehension.

The Professor drew towards him one of the boxes and opened the lid. He dipped his one useful hand into the box and, holding it aloft, allowed something which looked like wet sawdust to drip through his fingers. “That, gentlemen,” he said, with an air of the utmost contempt, “is what is known to the world as dynamite. I have nothing at all to say against dynamite. It has, in its day, been a very powerful medium through which our opinions have been imparted to a listening world, but its day is past. It is what the lumbering stage-coach is to the locomotive, what the letter is to the telegram, what the sailing-vessel is to the steamship. It will be my pleasant duty to-night to exhibit to you an explosive so powerful and deadly that hereafter, having seen what it can accomplish, you will have nothing but derision for such simple and harmless compounds as dynamite and nitro-glycerine.”
