HISTORY AND PRESENT ORGANIZATION.--Beginning in a small way in the Patent-Office building early in the century, the "Government" collections of "natural products" were transferred to the custody of the Smithsonian Institution in 1858, where they were installed along with the larger and more valuable collections of the institution. Twenty-three years later, in 1881, the present National Museum building was ready for the great mass of material that had accumulated in the Smithsonian building, and had been transferred from the Centennial Exhibition at Philadelphia. Out of these heterogeneous collections Dr. G. Brown Goode, under the direction of Secretary Baird, of the Smithsonian, organized a museum of broad scope, based on all that had proved best in museum experience to that time. Faithfully he carried forward the work until September, 1896, when his health broke under the strain of too many duties, and one of the best museum administrators the world has yet produced, if not the very best one, passed from us. In January, 1897, I was placed in temporary charge of the administration of the museum as an acting Assistant Secretary of the Smithsonian Institution, and remained in charge until July 1, 1898. On July 1, 1897, in order to meet changed conditions, a new plan of organization went into effect. The various divisions and sections of anthropology, biology, and geology, which had previously been conducted independently of one another, the curators and custodians reporting directly to the assistant secretary in charge of the museum, were united under three head curators--one of anthropology, another of biology, and a third of geology. This secured direct expert supervision, and correlated the work of each department. Before this such correlation had been impossible, owing to the large number of independent heads of sections and divisions in each department, who planned and executed the work more or less independently of one another. In the department of anthropology the system of installation inaugurated by Prof. W. H. Holmes is somewhat elaborate. The primary arrangement is founded, first, on the geographical or ethnographical assemblage, and, second, on the developmental or genetic assemblage. Other methods may be classed as special; they are the chronologic, the comparative, the individual, etc. The primary methods are adapted to the presentation of the general truths of anthropology, and the special methods are available for limited portions of the field.
