Fredericton New Brunswick Canada Vertical Declining Dial 397
A vertical declining dial 7 x 7 feet with parged cement face and 5 foot wrought iron gnomon. Plaque on wall reads "The sundial at the top of this wall is a faithful reconstruction of the original which Frederictonians used during the 1800s and early 1900s. The shadow cast by the gnomon (style) onto the dial accurately displays local apparent solar time." An equation of Time is included on the plaque to determine mean time. The date of the original construction of this sundial is not known, but the Soldiers Barracks were built in 1826. The dial was restored in 1992.
 
 
St. Louis Missouri USA Vertical Dial 396
A vertical decliner at the top of the Cupples I building. Given by the class of 1908. Can be seen from the courtyard of Robert S. Brookings building. In 1908 the campus newspaper, the Washington University Student Life, commented that "The new sun dial on Cupples I is now being put into position upon the tablet on the south side of the building?It will be interesting to note the discrepancy between sun time and standard time by comparing with the Varsity clock [a large time piece situated high on the west wall of Brookings Hall, with both clock and dial visible in the quadrangle]." Today the Baumont Pavilion, erected in 1965, blocks a close view of the ornate tablet and dial. Use binoculars from a distance.
