Portsmouth New Hampshire USA Horizontal Dial 130
Octagonal, approx 6 in. on a side Brass/Bronze Center compass rose, 4AM-8PM in Roman numerals. Standard stone pedestal. Probably not the original, as it is oversize for the dial plate.
 
 
Kingston Ontario Canada Horizontal Dial 129
A horizontal dial approximately 18 inches in diameter. Made of iron with a solid triangular gnomon Cast raised lettering, sun face, sea symbol. Hours marked by raised lines only. 7AM-5PM. On a small white plaque at the north of the dial are the words "Man eats his bread and records the hour; but the mills of the gods grind eternal flour." Very appropriate considering the dial rests on an old millstone. Update: as of Nov 1996 this dial no longer exists. The millstone is still there in front of City Hall, but the sundial and plaques are gone. Wrought iron base, supporting a large millstone on which the dial is mounted.
 
 
Toronto Ontario Canada Horizontal Dial 128
Approx 55 ft square Stone (concrete?) 4AM-8PM marked in Arabic numerals, half and quarter hours marked with lines. A huge dial. The gnomon is sunk below the outer level by a series of steps. The hours are marked by stone slab 'seats' spaced around the outer square. There are two seats at the noon position to allow for the width of the gnomon. This dial may have been destroyed by now in a rebuilding project.
 
 
Ottawa Ontario Canada Vertical Dial 127
Two vertical declining dials declining 58.1? west and 31.9? east on adjacent sides of the south corner of the Sisters of Charity of Ottawa Mother House. The western dial is approximately 7x8 feet and the eastern dial is approximately 7x4 feet. The dials are of gray plaster with black painted iron gnomons. The dials decline 58.1? west of south and 31.9? east of south. The western dial has hour lines from 10 AM to 7 PM and the eastern dial has hour lines from 7 AM to 3 PM. These dials predate the use of time zones and show local solar time. Mayall on p. 229; erroneously described this dial as on Mint Tower. LAMIRANDE, E., Elisabeth Bruyere, Foundress of Sisters of Charity of Ottawa, Ottawa, 1995, p. 207, "In the course of the same winter, Fr. Allard had built a double sundial of great dimension on the southwest angle of the house (corner of Bolton and Sussex streets) which, even today, continues to give the correct time, as it did in Mr. Bruyere's time; she greatly appreciated the convenience. The work presupposed an advanced knowledge of mathematics and astronomy. It was the first of its kind in Canada."

A unique bronze 12-3/8 inch octagonal horizontal dial with one main hour ring for local time and six subsidiary rings that give the time in London, Vienna, Constantinople, Jerusalem, Barbados and Mexico City.
