1820 Federal style building owned by the Univ. of Mass. at Dartmouth. Referred to as the Sundial building because of a vertical dial over the main entrance.
 
 
Burlington Vermont USA Vertical Dial 161
2'8" x 2' oval. Probably of Bronze. Gift of Mr. & Mrs. Willard Pope. Planned by Prof. Betty Bandel. Hour lines are curved to compensate for EoT. Rings indicate months. Difficult to read due to height above ground. (ca. 12' above ground level.) Dial faces approx 5 degrees East of due South. Built by W. M. Schenk.
 
 
Philadelphia Pennsylvania USA Horizontal Dial 160
A 1 foot diameter bronze horizontal dial. It was presented by National Association of Watch and Clock Collectors in 1991. However, the style angle is 52?.
 
 
Laramie Wyoming USA Horizontal Dial 159
An ornate 18 inch brass horizontal dial sits on a massive four-stone block pedestal. The dial has hour lines from 4am to 8pm, with hours in roman numerals. Time is graduated into 5-minute intervals. The 12-noon mark is 3/8 inch wide, allowing for the gnomon which is missing.
 
 
Philadelphia Pennsylvania USA Analemmatic Dial 158
Analemmatic dial with bronze standing figures.
 
 
Philadelphia Pennsylvania USA Horizontal Dial 157
A 1 foot diameter bronze horizontal dial on a square granite pedestal 3 feet tall. Possibly made in 18th century. Beautiful engraving.
 
 
Philadelphia Pennsylvania USA Horizontal Dial 156
A 1 foot diameter bronze horizontal dial in backyard garden. May be from 18th century. Gnomon is shaky for its bolts are loose. Style angle is about 51?, an angle for London, not for Philadelphia.
 
 
Philadelphia Pennsylvania USA Vertical Dial 151
Vertical dial on building. Recent stucco on building, resulting in no hour lines. Only a small gnomon below a second story window.
 
 
Philadelphia Pennsylvania USA Horizontal Dial 150
A 21 inch diameter horizontal dial on three foot brick pedestal. Hour lines only. Gnomon reclined. Made in 1989 to commemorate Bicentennial of the General Assembly Presbyterian Church (USA). Visible through locked gates.
 
 
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.

Franklin Center Pennsylvania USA Equatorial Dial 139
A modernistic equatorial dial about 6 feet in diameter. The analemma shaped gnomon casts Eastern standard time onto a wide metal semicircle band. The hours with 10-minute marks are inscribed on the center of the equatorial band. This unique sundial tells the time, indicates the approximate day of the month and projects the zodiacal constellation signs as they are aligned with the sun and the earth in this era. It is accurate to within two minutes.
