Over the past 42 years clay smoking pipes have been excavated from two U.S. army posts, Fort Hoskins (35BE15) and Fort Yamhill (35PO75) and curated at Oregon State University. These two forts were established in Western Oregon in 1856 and by 1866 both had been decommissioned. Numerous theses have focused on the lives of the men assigned to the forts, but none have focused on the clay pipe, a ubiquitous find at many historic sites. This simple object can often communicate information about human social, economic and status cultures. The military forts were restricted environments in which daily activities were restrained. One means in which someone could express their individuality was with a pipe. This thesis examines clay pipes and combines extensive archival research, journals of soldiers stationed at each fort, with comparison data of previous clay pipe research and consultation with experts in the field to help in their identification. The impact of smoking upon the health and psyche of the men within the military milieu of the forts is examined, as is consumer choice, availability of clay pipes and expressions of status. This thesis presents evidence to support definitive and tentative conclusions for the identification of clay pipe manufacturers and conjecture on consumer choice.
