Though the main object of the expedition was the prosecution of the observations in terrestrial magnetism and meteorology, it was possible to obtain a large collection of articles illustrating the arts and industries of the Eskimo of the region, with whom the most friendly relations were early established. Nearly all of the collection was made by barter, the natives bringing their weapons, clothing, and other objects to the station for sale. Full notes on the habits and customs of the Eskimo also were collected by the different members of the party, especially by the commanding officer; the interpreter, Capt. E. P. Herendeen; the surgeon, Dr. George Scott Oldmixon, and myself, who served as one of the naturalists and observers of the expedition. It fell to my share to take charge of and catalogue all the collections made by the expedition, and therefore I had especially favorable opportunities for becoming acquainted with the ethnography of the region. Consequently, upon the return of the expedition, when it was found that the ethnological observations would occupy too much space for publication in the official report,[N1] all the collections and notes were intrusted to me for the purpose of preparing a special report. The Smithsonian Institution, through the kindness of the late Prof. Spencer F. Baird, then secretary, furnished a room where the work of studying the collection could be carried on, and allowed me access to its libraries and to the extensive collections of the National Museum for the purposes of comparison. The Director of the Bureau of Ethnology, Maj. J. W. Powell, kindly agreed to furnish the illustrations for the work and to publish it as part of his annual report, while the Chief Signal Officer, with the greatest consideration, permitted me to remain in the employ of his Bureau until the completion of the work. [Footnote N1: Report of the International Polar Expedition to Point Barrow, Alaska, by Lieut. P. H. Ray, Washington, 1885.] Two years were spent in a detailed analytical study of the articles in the collection, until all the information that could be gathered from the objects themselves and from the notes of the collectors had been recorded. Careful comparisons were made with the arts and industries of the Eskimo race as illustrated by the collections in the National Museum and the writings of various explorers, and these frequently resulted in the elucidation of obscure points in the history of the Point Barrow Eskimo. In the form in which it is presented this work contains, it is believed, all that is known at the present day of the ethnography of this interesting people. Much linguistic material was also collected, which I hope some time to be able to prepare for publication.
