delays and discouragements, it was carried to a triumphant success. Before the end of the year (1887) the committee had held numerous meetings, prepared and issued a circular, and engaged the co-operation of several other organizations with the Academy of Sciences, including the American Ornithologists' Union, the Agassiz Association, and the Audubon Society (for the protection of our native birds). A design was proposed by the academy's committee, and adopted by the joint committee of the several societies; this design originated with Professor Egleston, and was a striking combination of the religious, scientific, and artistic elements appropriate to the purpose. The scheme was that of a Runic cross, the only form of that Christian symbol which can properly bear ornamental devices, according to the canons of artists and architects, and this was to be covered with reliefs of the birds, quadrupeds, and flowers that Audubon so loved and studied, and that have given him his fame as the artist-naturalist of America. The general design being approved, the selection and arrangement of the animals and birds was given to a subcommittee of specialists, consisting of Dr. J. A. Allen, Mr. G. B. Sennett, and Dr. N. L. Britton, whose duty was to secure accurate representation and artistic grouping of the forms. In all these combined aspects this monument is doubtless unique. As it stands to-day over the grave of him whom it commemorates--graceful, dignified, and altogether peculiar--it is an honor to our city, as well as a fitting tribute to the memory of Audubon, the Nature-lover, the artist, and the Christian believer. For this beautiful thought, so nobly carried out, both American science and the city of New York are indebted to Thomas Egleston. The progress of the effort was slow; it was not until 1891 that sufficient subscriptions were secured, and not until the spring of 1893 that all was ready for the formal ceremonies. During all this time Professor Egleston and Dr. Britton were untiring in their endeavors and unfaltering in their purpose to succeed. On April 26, 1893, the monument was dedicated with suitable exercises, of great interest, at Trinity Cemetery, and a memorial address upon the life and work of Audubon was delivered by Mr. Daniel G. Elliott, F. R. S. E., of the Ornithologists' Union, at a public meeting at the American Museum of Natural History.
