He was born in Brandon, Vermont, to a family of old settlers. He went to study at Middlebury College where he took an interest in natural history, influenced by Ezra Brainerd and Henry M. Seely. He received a BS in 1884 and an MS in 1887. He visited the US National Museum in Washington in 1884 while preparing an exhibit for the World Cotton Centennial in New Orleans and came in contact with palaeobotanist Lester F. Ward there. He later became an assistant to Ward on the Geology Survey during which time he studied fossil wood in the lignites of the Potomac. He joined the Geological Survey as an assistant paleontologist in 1894 and was promoted to be a geologist in 1907. He joined the Columbian College as a professor of botany and received a PhD in 1896.
