On June 14, 1777, the Second Continental Congress adopted a resolution stating that the official American Flag should have thirteen stripes, alternating between red and white, thirteen stars, to represent the states in the union, and a blue field to represent this new constellation. June 14 officially became National Flag Day in 1949. On Flag Day 1914, Franklin Knight Lane, then Secretary of the Interior under President Woodrow Wilson, presented this speech to the employees of the Department of Interior. I transcribed it in Anniversary Gregg.
