Mt. Vernon Virginia USA Horizontal Dial 167
A bronze octagonal horizontal dial about 12 inches on a side. Original dial is badly worn and virtually illegible; this original is now stored inside the museum. A 6 inch replica of the dial is located on a pedestal in the center of a circular lawn. This replica has an 8-pointed compass rose in the center and Roman numerals from 5 AM to 7 PM. The hour intervals are graduated into two-minute increments, with Arabic numerals 20-40-60 at appropriate places between the hour lines. Pictures of both the replica and the original dial are in the Image Archive.

Philadelphia Pennsylvania USA Vertical Dial 149
On wall of the passage from hallway to kitchen inside the house, just for exhibition. 9.5 x 19 inches, rough wood painted in black, roman numerals from 8 am to 5 pm on 1.5 inches wide frame, it was for hanging on a declining wall. Black iron gnomon rod, 1 foot in length, is supported with iron vine which is fixed to a point on the dial plate about 1.5 inches from the noon line. Unfortunately, the gnomon seems twisted, so that it points down over the noon line, like those for dials facing true south. Admission fee: $5.00 for guided tour. No photo allowed inside.
Philadelphia Pennsylvania USA Horizontal Dial 148
Horizontal dial approximately one foot diameter mounted on old stone atop a 3 foot stone pedestal. It is sitting against north wall of the garden and not aligned in proper direction. Plaque at the base states "This sundial stood for over a century in the gardens of Dorchester House, Park Lane, London, England. Presented by The Soroptomist Club of Philadelphia, December 23, 1935". This may be true for the dial plate because the hour angles indicate a latitude of 51°, the London latitude. It may not be true for the gnomon, whose style angle is 40°, the Philadelphia latitude. Access by taking guided tour, $5; then ask for garden.
Philadelphia Pennsylvania USA Vertical Dial 147
A vertical dial within a bronze sunflower held overhead in the outstretched arms of the bronze sculpture of two children.
