This report was written by Frederic F. Mellen of Jackson, Mississippi. Mellen was a descendant of Arthur F. Hopkins, a Lawrence County delegate to the 1819 constitutional convention. Mellen recounts his experience at the sesquicentennial events on August 2, 1969, including the birthday luncheon and the ceremony commemorating the signing of the 1819 constitution. He notes that "it is pleasing to see and realize how Huntsville has grown, and that now it is a vast educational and scientific research and development center."
