354 APPENDIX et 3s family all these years, I think it is in a large measure due to the sweet temper, the calmness, the courtesy and the example of unselfishness which Professor Clark has always given us. I remember one other episode when, a few years after he came to Columbia, he turned over to me for criticism the manuscript of his book. I recollect reading it on my way to New England where I was spending the holidays. I was so excited after reading it that I telegraphed or wrote to him saying: “You have earned your place among the six leading economists of the nineteenth century.” That first impression made upon me by the perusal of the wonderful book has, of course, been abundantly strengthened, as we all know of the international reputation which Professor Clark speedily achieved. It is unnecessary for me to say much more now because we shall hear, not from all of the eighty, but from a few of his well-wishers. When his friends bethought themselves of how they could most fittingly celebrate this anniversary, they finally decided upon three different plans. One was the accumulation through his admirers of a fund, which has enabled us to secure the fine portrait which you have seen in the other room, and of which a duplicate has been painted for the trustees of the Carnegie Foundation. The second was the adoption of a very good, old continental custom. When a scholar reaches a ripe age, it is the custom in Germany, and in France, as well as in other countries, to prepare what they term a jubilee volume, but which we now might more suitably call simply a commemo- rative volume. This task has been undertaken under the auspices of the American Economic Association, by a former President of the American Economic Association and one of Professor Clark’s own pupils, who is, I am happy to say, with us tonight. Professor Hollander of Johns Hopkins has almost ready for the press what we confidently hope will be a dignified and appropriate tribute to our beloved colleague. The third plan of signalizing this anniversary was what you see here tonight, this tribute of esteem and of respect on the part of his colleagues and fellow citizens. This at one time gave us no little concern, because we knew that it would have been exceedingly easy to have, instead of eighty, eight hundred guests. We finally decided that this more intimate and, may I say, select assemblage, would be more agreeable to our friend; so here we are. In these three special ways his colleagues and his admirers have sought to show their appreciation of what he is and of what he has done. Without detaining you longer, I shall now call upon the speakers, each of whom will approach the subject in a little different way. I shall first call upon our “benevolent despot.” President Butler.
