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.”

The Professor looked with kindly sympathy over his audience as he allowed the yellow mixture to percolate slowly through his fingers back into the box again. Ever and anon he took up a fresh handful and repeated the action.

The Anarchists in the audience exchanged uneasy glances one with the other.

“Yet,” continued the Professor, “it will be useful for us to consider this substance for a few moments, if but for the purpose of comparison. Here,” he said, diving his hand into another box and bringing up before their gaze a yellow brick, “is dynamite in a compressed form. There is enough here to wreck all this part of London, were it exploded. This simple brick would lay St. Paul’s Cathedral in ruins, so, however antiquated dynamite may become, we must always look upon it with respect, just as we look upon reformers of centuries ago who perished for their opinions, even though their opinions were far behind what ours are now. I shall take the liberty of performing some experiments with this block of dynamite.” Saying which the Professor, with his free arm, flung the block of dynamite far down the aisle, where it fell on the floor with a sickening thud. The audience sprang from their seats and tumbled back one over the other. A wild shriek went up into the air, but the Professor gazed placidly on the troubled mob below him with a superior smile on his face. “I beg you to seat yourselves,” he said, “and for reasons which I have already explained, I trust that you will not applaud any of my remarks. You have just now portrayed one of the popular superstitions about dynamite, and you show by your actions how necessary a lecture of this sort is in order that you may comprehend thoroughly the substance with which you have to deal. That brick is perfectly harmless, because it is frozen. Dynamite in its frozen state will not explode—a fact well understood by miners and all those who have to work with it, and who, as a rule, generally prefer to blow themselves to pieces trying to thaw the substance before a fire. Will you kindly bring that brick back to me, before it thaws out in the heated atmosphere of this room?”

One of the men stepped gingerly forward and picked up the brick, holding it far from his body, as he tip-toed up to the platform, where he laid it down carefully on the desk before the Professor.

“Thank you,” said the Professor, blandly.

The man drew a long breath of relief as he went back to his seat.

“That is frozen dynamite,” continued the Professor, “and is, as I have said, practically harmless. Now, it will be my pleasure to perform two startling experiments with the unfrozen substance,” and with that he picked up a handful of the wet sawdust and flung it on a small iron anvil that stood on the table. “You will enjoy these experiments,” he said, “because it will show you with what ease dynamite may be handled. It is a popular error that concussion will cause dynamite to explode. There is enough dynamite here to blow up this hall and to send into oblivion every person in it, yet you will see whether or not concussion will explode it.” The Professor seized a hammer and struck the substance on the anvil two or three sharp blows, while those in front of him scrambled wildly back over their comrades, with hair standing on end. The Professor ceased his pounding and gazed reproachfully at them; then something on the anvil appeared to catch his eye. He bent over it and looked critically on the surface of the iron. Drawing himself up to his full height again, he said,

“I was about to reproach you for what might have appeared to any other man as evidence of fear, but I see my mistake. I came very near making a disastrous error. I have myself suffered from time to time from similar errors. I notice upon the anvil a small spot of grease; if my hammer had happened to strike that spot you would all now be writhing in your death-agonies under the ruins of this building. Nevertheless, the lesson is not without its value. That spot of grease is free nitro- glycerine that has oozed out from the dynamite. Therein rests, perhaps, the only danger in handling dynamite. As I have shown you, you can smash up dynamite on an anvil without danger, but if a hammer happened to strike a spot of free nitroglycerine it would explode in a moment. I beg to apologize to you for my momentary neglect.”

A man rose up in the middle of the hall, and it was some little time before he could command voice enough to speak, for he was shaking as if from palsy. At last he said, after he had moistened his lips several times:—

“Professor, we are quite willing to take your word about the explosive. I think I speak for all my comrades here. We have no doubt at all about your learning, and would much prefer to hear from your own lips what you have to say on the subject, and not have you waste any more valuable time with experiments. I have not consulted with my comrades before speaking, but I think I voice the sense of the meeting.” Cries of “You do, you do,” came from all parts of the hall. The Professor once more beamed upon them benevolently.

“Your confidence in me is indeed touching,” he said, “but a chemical lecture without experiments is like a body without a soul. Experiment is the soul of research. In chemistry we must take nothing for granted. I have shown you
