The writings of Mr. Du Bois were numerous, and continued up to the year of his death. His papers on numismatics were frequent and always attractive, his last appearance in print being in April of this year, in an article on the “Coinage of the Popes.” To the “American Philosophical Society,” of which he was elected a member in 1844, he made various communications on behalf of Mr. Eckfeldt and himself, mostly on topics suggested by experiences in the assay department. Among the most curious was one on “The Natural Dissemination of Gold,” by which we were astonished to learn that this precious metal is found in appreciable quantity in the clays underlying our city. In 1869 he wrote for the “Bankers’ Magazine,” “Propositions for a Revised System of Weights, and a Restoration of Silver Currency.” The development of his views on these subjects is a model of clear exposition, and the conclusions reached were such as might be expected from a mind aiming to attain practical results rather than to impose visionary theories. From the beginning he was highly esteemed at the Mint. It was his ambition to acquire a knowledge of every branch of the service, and with his capacity and opportunities this end was attained. He early became the trusted friend and counsellor of his colleagues, and was able to serve them in many ways, perhaps most of all with his ready pen. As time passed, and forty-eight years of experience was given to him, he was recognized by all as the Nestor of the Mint service. And here I pause to draw a lesson, from the example of Mr. Du Bois’s life, as to the value of a properly organized civil service. In the department with which he was connected, political tests were never obtruded, and permanence of tenure followed on merit. On no other basis could his services have been claimed or retained. They would have been transferred to a private sphere, probably to his pecuniary gain, certainly to the public loss. He was very accessible, and ever ready to lend aid from the stores of his knowledge, but in particular did he delight to instruct and bring forward his younger friends. Mr. Du Bois was able to fulfill his official duties until within a few months of his death. He was fully conscious of his approaching end, preserving his intelligence to the last, and the faith which had comforted him in this life supported him at its close. The following minute was adopted at a meeting of the officers and employees after his decease:
