The writer offered personally to convince the Minister of the truth of his assertions, provided they could go to some remote spot where the results of the explosion would do no damage, and where they would be safe from espionage. The writer went on very frankly to say that if the Minister consulted with the agents of the police, they would at once see in this invitation a trap for the probable assassination of the Minister. But the inventor claimed that the Minister’s own good sense should show him that his death was desired by none. He was but newly appointed, and had not yet had time to make enemies. France was at peace with all the world, and this happened before the time of the Anarchist demonstrations in Paris. It was but right, the letter went on, that the Minister should have some guarantee as to the bona fides of the inventor. He therefore gave his name and address, and said if the Minister made inquiries from the police, he would find nothing stood in their books against him. He was a student, whose attention, for years, had been given to the subject of explosives. To further show that he was entirely unselfish in this matter, he added that he had no desire to enrich himself by his discovery. He had a private income quite sufficient for his needs, and he intended to give, and not to sell, his secret to France. The only proviso he made was that his name should be linked with this terrible compound, which he maintained would secure universal peace to the world, for, after its qualities were known, no nation would dare to fight with another. The sole ambition of the inventor, said the letter in conclusion, was to place his name high in the list of celebrated French scientists. If, however, the Minister refused to treat with him he would go to other Governments until his invention was taken up, but the Government which secured it would at once occupy the leading position among nations. He entreated the Minister, therefore, for the sake of his country, to make at least one test of the compound.

It was, as I have said, before the time of the Paris explosions, and ministers were not so suspicious then as they are now. The Minister made inquiries regarding the scientist, who lived in a little suburb of Paris, and found that there was nothing against him on the books of the police. Inquiry showed that all he had said about his own private fortune was true. The Minister therefore wrote to the inventor, and named an hour at which he would receive him in his private office.

The hour and the man arrived together. The Minister had had some slight doubts regarding his sanity, but the letter had been so straightforwardly written, and the appearance of the man himself was so kindly and benevolent and intelligent that the doubts of the official vanished.

“I beg you to be seated,” said the Minister. “We are entirely alone, and nothing you say will be heard by any one but myself.”

“I thank you, Monsieur le Ministre,” replied the inventor, “for this mark of confidence; for I am afraid the claims I made in the letter were so extraordinary that you might well have hesitated about granting me an interview.”

The Minister smiled. “I understand,” he said, “the enthusiasm of an inventor for his latest triumph, and I was enabled thus to take, as it were, some discount from your statements, although I doubt not that you have discovered something that may be of benefit to the War Department.”

The inventor hesitated, looking seriously at the great official before him.

“From what you say,” he began at last, “I am rather afraid that my letter misled you, for, fearing it would not be credited I was obliged to make my claims so mild that I erred in under-estimating rather than in over-stating them. I have the explosive here in my pocket.”

“Ah!” cried the Minister, a shade of pallor coming over his countenance, as he pushed back his chair. “I thought I stated in my note that you were not to bring it.”

“Forgive me for not obeying. It is perfectly harmless while in this state. This is one of the peculiarities—a beneficent peculiarity if I may so term it—of this terrible agent. It may be handled with perfect safety, and yet its effects are as inevitable as death,” saying which, he took out of his pocket and held up to the light a bottle filled with a clear colorless liquid like water.
