This thick volume contains about 700 letters written by Gouverneur M. Ogden as Treasurer of Columbia College from December 15, 1868 to May 16, 1877. They provide a fascinating insight into the workings of this important institution. About one third of the letters are addressed to F. A. P. Barnard, President, and give a fine picture both in overview and in detail of most aspects of the college. Numerous letters are to professors like Charles F. Chandler, Henry Drisler, Thomas Egleston, Charles A. Joy, and Ogden N. Rood, with a few to Theodore W. Dwight, Asa Gray, and Jay Gould.
