label: Description
content: Sisters Elizabeth Henshaw Metcalf (1852–1925) and Sarah Spathding Metcalf (1858–1939) donated this rule to the Smithsonian in 1931, within several containers of materials sent from the family home in Worcester, Mass. The bulk of the materials were ethnographic specimens collected by the women as they visited and lived in the Philippines at various times between 1905 and their deaths. The name on the rule probably refers to their brother, Wallace Metcalf (1854–1904). He graduated from Worcester Polytechnic Institute with a degree in mechanical engineering in 1873, lived with his sisters for many years, and worked in Worcester as a civil engineer.
