Abstract: This collection includes material pertaining to Charles Irving Clay’s professional and personal life. These letters sent to
Clay, and occasionally sent from Clay, provide information on how ornithological research and business was conducted in the
early 20th century. Included in the professional correspondence is information related to the purchase of “skins”, nests,
and other specimens for the study of birds and particularly oology. The correspondence with family and friends offers insight
into how communication was conducted in a more casual way about everyday life, familiar connections and some personal gossip.
The series of photographs captures people in a wide variety of scenarios, images of cars, buildings from travels around the
country, as well as several different bird and nest specimens.
Language of Material: English
