In conclusion, the editor wishes to express his obligations to the many speakers and officers of the Congress, who have evinced great interest in the publication and assisted by valuable suggestions and advice. In particular, he acknowledges the help of President Butler of Columbia University, Professor Münsterberg of Harvard University, and Professor Small of the University of Chicago. Acknowledgments are with justice and pleasure made to the Committee on Congresses of the Exposition, and the able chairman, Hon. Frederick W. Lehmann, for their unwavering and prompt support on all matters of policy and detail, without which the full measure of success could not have been achieved. To the efficient secretary of the Department of Congresses, Mr. James Green Cotchett, an expression of obligation is due for his indefatigable labors during the Congress period, and for his able and painstaking work in compiling the detailed records of this publication. At a meeting of the Executive Committee of the Exposition on January 3, 1905, there was unanimously voted the following resolution, recommended by the Administrative Board and approved by the Committee on Congresses:-- MOVED: that a vote of thanks and an expression of deepest obligation be tendered to Dr. Simon Newcomb, President of the Congress, Prof. Hugo Münsterberg, vice-president of the Congress, and Prof. Albion W. Small, vice-president of the Congress, for their efficient, thorough, and comprehensive work in connection with the programme of the Congress, the selection and invitation of speakers, and the attention to detail in its execution. That, in view of the enormous amount of labor devolving upon these three gentlemen for the past eighteen months, to the exclusion of all opportunities for literary and other work outside their college departments, an honorarium of twenty-five hundred dollars be tendered to each of them. At a subsequent meeting the following resolution was also passed:-- MOVED: that the Directors of the Louisiana Purchase Exposition Company place upon the record an expression of their appreciation of the invaluable aid so freely given by the Administrative Board of the Congress of Arts and Science. In organization, guidance, and results the Congress was the most notable of its kind in history. For the important part performed wisely and zealously by the Administrative Board the Exposition Management extends this acknowledgment. SUMMARY OF EXPENSES OF THE CONGRESS
