REPORT OF THE ASSISTANT DIRECTOR OF THE UNITED STATES NATIONAL MUSEUM FOR 1882. Prof. SPENCER F. BAIRD, Director of the United States National Museum : SIR: I have the honor to submit herewith a report upon the work of the Museum for the year 1882, in which are included certain suggestions relative to the administration of the Museum, which may at some future time, either in their present form or with modifications, be recommended for adoption. Very respectfully, G. BROWN GOODE, U. S. NATIONAL MUSEUM, January 1, 1883. Assistant Director. With the beginning of the year 1882 systematic work in the reorganization and installation of the collections may be said to have been fairly commenced. Although something had been accomplished in the three or four months prior to the above date, the work was, for the most part, experimental. The year 1882 may, therefore, be regarded as the first year of the occupation of the new building. On January 1, 1882, was issued Circular No. 1, containing a plan of organization and regulations. This pamphlet contains 58 pages, and in it are defined the limits of each department of work, the duties of every officer, and the routine to be followed in each kind of administrative work. This code of regulations has been systematically enforced during the year with consequent important improvement in the efficiency of each department. Cases. Much thought and time have been expended in making experiments for the purpose of ascertaining what forms of cases are most suitable for the exhibition of our collections. Old patterns have been modified and new ones invented. A detailed account of these experiments, and their results, will be submitted at some future time. Four thousand five hundred and eighty-six cases and boxes of various patterns have been received, as specified in the accompanying schedule. They have *See Appendix to Proceedings United States National Museum, Vol. IV, following page 534. been, as a rule, constructed by contract after the specifications had been submitted for competition to a number of reliable firms in Washington, Baltimore, and Philadelphia. The glass has been imported free of duty, the locks and other hardware purchased of manufacturers, and the finishing of the wood-work, the setting of the glass, and the fitting up of the interiors with shelves, and otherwise preparing them for the reception of specimens, have been done by a force of men working in the Museum building, paid by the day or job, as was found in each particular instance to be more economical and satisfactory. The adoption of a peculiar style of case, known as the "unit-box," for the exhibition of many classes of objects, has rendered it necessary to employ a number of mechanics in mounting the specimens for display. In this work several women have been employed, who have proved to be industrious and skillful. The following is a list of cases in use in the Museum and for the most part received during the year: Case A (3. 3). Pier uprights, 8' 6" x 3' 3" x 9' 28 Labels. Similar experiments have been made in regard to labels, many different styles of type and colors of paper and methods of arrangement having been tried. It has been found necessary to employ |
