McGuire's book, St. Louis Arsenal - Armory Of The West is a picture of the sundial for which the caption reads "On December 12, 1859, master armorer N. Engels, machinist A. Schaedel, and engraver W. Hawksley dedicated a sundial, which they had created entirely from spare ordnance materials. It was a scientifically precise instrument, measuring 17 inches in diameter, and was used for many years as the definitive chronometer of the arsenal. Engraved upon it was a poem entitled 'The Bird of Liberty,' reflecting the patriotic fervor of the day."
