There is not space here to detail the circumstances under which he was led to prepare, in 1863, the Plan for a School of Mines in New York; but the modest little outline then drawn up and printed has been exceedingly rich in results. It was taken up with interest by certain leading trustees of Columbia College, as it was then called, especially by the late George T. Strong. The president, the late Dr. Charles King, and a majority of the board, favored the experiment, for so it was regarded, and arrangements were finally made to begin it in the autumn of the next year, in limited quarters in the old college building on Forty-ninth Street, and with provision for but a small number of students--not over twenty. Part of the instruction was to be given by members of the existing college faculty; and three new professors were appointed to special chairs for the school, to be compensated wholly by fees therefrom. These were, Professor Egleston, mineralogy and metallurgy; Prof. Francis Vinton, mining engineering; and Dr. C. F. Chandler, chemistry. Meanwhile, in June, 1864, President King was succeeded by the late Dr. Barnard, whose strong interest in science made him a warm supporter of the school. Already some prominent people were impressed with the value of such a movement, and disposed to aid it. A fine collection of minerals was purchased and presented by Mr. Strong, and another was given by Mr. Gouverneur Kemble. On the opening day, November 15, 1864, the number of applicants was far beyond expectation and provision; the school was found to respond to a need and a demand that had not been suspected; it was a success from the first. In a year or two it had become an institution of recognized importance; ample quarters were provided for it in a large building, formerly a manufactory, on the Fourth Avenue side of the college block, and important additions were made to its corps of instructors--particularly the eminent geologist, Dr. J. S. Newberry, of Cleveland, Ohio, whose noble geological collection was deposited and used in the School of Mines, and whose breadth and power and personal magnetism so profoundly influenced scientific interest and progress in the city of New York for more than twenty years. Such was the beginning of the school; its career has been one of unbroken growth and increasing influence. After some ten years it was found needful to take down the plain old transformed factory and erect a new building on its site, with larger space and improved facilities. Fifteen years later Columbia College was removed to its new site on the Morningside Heights, where now the School of Mines is installed in stately fireproof structures, wherein its great accumulated treasures of collections, apparatus, models, and varied appliances of instruction are safely and permanently housed.
