Excerpt from Explorations and Field-Work of the Smithsonian Institution in 1915
The Smithsonian Institution every year initiates or cooperates with other institutions in numerous expeditions to various parts of the world in the interest of theoretical and practical science. Accounts of the principal expeditions engaged in during the year 1915 are presented herein chie¿y in the words of the investigators themselves, while those of more than routine importance are signed with the names of the writers. The various lines of research include geology, zoology, botany, anthropology, physics, and astrophysics.
Of the several branches of the Institution, only the United States National Museum, the Bureau of American Ethnology, and the Astro physical Observatory are mentioned in this account as having engaged in field-work. The National Museum has no specific funds for this purpose, but whenever possible embraces Opportunities to take part in natural history investigations and to add to its collections and exhibition series. Researches in American ethnology consist largely of field-work among the Indian tribes, detailed accounts of which will be found in the annual reports of the Bureau. The Astrophysical Observatory undertakes expeditions here and abroad for the purpose of observations in connection with its regular work of studying the physical properties of the sun and their effects on the earth.
