There are now more than twelve thousand Members who are contribut- ing to the work of the Museum. MEMBERSHIP 9 If you believe that the Museum is doing a useful service to science and lo education, the Trustees invite you to lend your support by becoming a Member.

The services of an Instructor for guidance when visiting the Museum HISTORY AND WORK OF THE MUSEUM 11 THE HISTORY AND WORK OF THE MUSEUM Sixty-one years of public and scientific service have won for the American Museum of Natural History a position of recognized im- portance in the educational and scientific life of the nation and in the progress of civilization throughout the world. With every passing year the influence of the Museum widens, as is witnessed by the increasing numbers of visitors who daily enter its halls without the payment of any admission fee whatever. The American Museum of Natural History was founded and in- corporated in 1869 for the purpose of establishing a Museum and Library of Natural History; of encouraging and developing the study of Natural Science; of advancing the general knowl- edge of kindred subjects, and to that end of furnishing popular instruc- tion. For eight years its home was in the Arsenal in Central Park, during which time many important collections were secured. History The cornerstone of the present building in Manhattan Square was laid in 1874 by President U. 8. Grant; in 1877 the first section (South Central Wing) was completed, and on December 22, 1877, the Museum was formally opened by President R. B. Hayes. In 1880 the educational work with the schools was inaugurated by Professor Albert 8. Bickmore. In 1893 the Museum was opened to the public on Sundays, and in 1907 it was opened free to the public every day in the year. The Museum building is one of the largest municipal structures in the City, and has cost to date approximately $16,000,000. The South Fagade is 710 feet in length; the total floor area is about fifteen acres. The structure is designed when completed to occupy all of Manhattan Square. The building is erected and largely maintained by the City, through the Department of Parks. Building funds are provided for by issues Administration Of Corporate Stock, which have been made at intervals and Support since 1871. The annual appropriation, known as the Maintenance Fund, is devoted to the heating, lighting, repair and supervision of the building and care of the collections. The Museum is under the control of a self-perpetuating Board of Trustees, which has the entire direction of its activities as well as the guardianship of all the collections and exhibits. The Trustees give their services without remuneration. 12 SUPPORT OF THE MUSEUM The funds which enable the Trustees to purchase specimens, to carry on explorations and various forms of scientific work, to prepare and publish scientific papers and to enlarge the library, are contributed by the Trustees, Members and other friends. The interest of the Endowment Fund, which includes the munifi- cent bequest of Mr. and Mrs. Morris K. Jesup (1909-1917), may be used for additions to the collections, research, and for publication. It cannot be used for the care or repair of the building, construction of cases or other maintenance work for which the City provides. The Membership Fund, derived from the subscriptions of Members, may be devoted to any purpose and is of particular importance in promot- ing the educational work and growth of the Museum. Voluntary contributions may be used for general purposes or for such special object as the donor may designate; some of the most valuable and important collections have been obtained by such gifts, as for example the Morgan collection of gems and the Juilliard collection of ancient Peruvian pottery and textiles. In the last edition of the Century Dictionary a museum is defined as: ‘“‘A collection of natural objects, or of those made or used by man, Definition of | placed where they may be seen, preserved, and studied. a Museum Neither the objects themselves, nor the place where they are shown, constitute a museum; this results from the com- bination of objects, place, and purpose, display being an essential feature. The objects, or specimens, may be shown for general purposes only, or for the illustration of some subject or idea, the tendency of modern museums being, by the display of objects and the manner in which they are arranged and labeled, to illustrate some fact in nature or in the history of mankind.” And I. Ray Lankester as Director of the British Museum of Natural History stated that: “The purposes of a great national museum of natural history are: (1) To procure by its own explorers or by the voluntary assistance Purposes of Of independent naturalists the actual specimens upon Museums which accurate knowledge of the animals, plants, and minerals of the earth’s surface, and more especially of the national territory, is based; to preserve and arrange these collections for study by expert naturalists, and to facilitate, directly or indirectly, the w WORK OF THE MUSEUM lL; publication (in the form of catalogues or monographs) of the knowledge so obtained—with a view to its utilization, not only in the progress of science, but in the service of the State. (2) To exhibit in the best possible way for the edification of the public, at whose charges these collections are made and maintained, such specimens as are fitted for exposure in publie galleries, with a view to the intelligent and willing participation of the people in the maintenance of the Museum.”’ As the Museum is emphatically for the people, special attention is given to making the exhibits attractive and interesting as well as instructive. While The American Museum of Natural History cannot claim to have originated the idea of displaying animals amid their natural sur- roundings, it was the first large museum in this country to adopt this method, which it has since carried out on a large seale in the well-known habitat groups (see Guide Leaflet, No. 53, ‘‘The Story of Museum Groups”). How it has been developed, the visitor may judge by compar- ing the group of Robins and the Orizaba, Wolf or Hopi Groups. In this Museum were also developed the methods of preparing and mounting the skeletons of extinct animals that have resulted in such mounts as Brontosaurus and Tyrannosaurus, and the series showing the development of the horse, so that they might be something more than an assemblage of uninteresting bones. The Museum maintains exhibits “‘for the edification of the public.”’ The collections are brought together through gifts, exchanges with other institutions, through purchases and by means of explorations in various parts of the world. The educational work performed by these specimens and _ their accompanying labels is supplemented by lectures and publications of a How These Popular nature. A course of evening lectures is given Purposes are every Spring and Fall for the Members, to which admission Carried out .- : tis A : is to be had by ticket; also courses of Science Stories are given on Saturday mornings for the children of members. Other series, under the direction of the Museum’s Department of Public Edueation, are given for the children of the Public Schools; to students of the high schools, training schools, and colleges, also cultural courses for teachers. Special lectures for the blind are pro- vided for by the Jonathan Thorne Memorial Fund. Lectures Scientific Societies meet at the Museum and from time to time offer Jectures of general interest. 14 ENTRANCE ARCHWAY Radio talks are given in connection with some of the activities of the Museum. The publications of the Museum are noted on pages 130 and 136.
