It is a pleasure for me to remember that at the close of my remarks, which I took pains to make entirely courteous to Dr. Allaben, he came to me, and strongly opposed as we were in politics, he grasped me by the hand most heartily, expressed his amazement at seeing these assignats, mandats, and other forms of French revolutionary issues, of which he had never before seen one, and thanked me for refuting his arguments. It is one of the very few cases I have ever known, in which a speech converted an opponent. Perhaps a word more upon this subject may not be without interest. My attention had been drawn to the issues of paper money during the French Revolution, by my studies of that period for my lectures on modern history at the University of Michigan, about five years before. In taking up this special subject I had supposed that a few days would be sufficient for all the study needed; but I became more and more interested in it, obtained a large mass of documents from France, and then and afterward accumulated by far the largest collection of French paper money, of all the different issues, sorts, and amounts, as well as of collateral newspaper reports and financial documents, ever brought into our country. The study of the subject for my class, which I had hoped to confine to a few days, thus came to absorb my leisure for months, and I remember that, at last, when I had given my lecture on the subject to my class at the university, a feeling of deep regret, almost of remorse, came over me, as I thought how much valuable time I had given to a subject that, after all, had no bearing on any present problem, which would certainly be forgotten by the majority of my hearers, and probably by myself. These studies were made mainly in 1859. Then the lectures were laid aside, and though, from time to time, when visiting France, I kept on collecting illustrative materials, no further use was made of them until this debate during the session of the State Senate of 1864. Out of this offhand speech upon the assignats grew a paper which, some time afterward, I presented in Washington before a number of members of the Senate and House, at the request of General Garfield, who was then a representative, and of his colleague, Mr. Chittenden of Brooklyn. In my audience were some of the foremost men of both houses, and among them such as Senators Bayard, Stevenson, Morrill, Conkling, Edmunds, Gibson, and others. This speech, which was the result of my earlier studies, improved by material acquired later, and most carefully restudied and verified, I repeated before a large meeting of the Union League Club at New York, Senator Hamilton Fish presiding. The paper thus continued to grow and, having been published in New York by Messrs. Appleton, a cheap edition of it was circulated some years afterward, largely under the auspices of General Garfield, to act as an antidote to the ``Greenback Craze'' then raging through Ohio and the Western States.
