Halifax Nova Scotia Canada Armillary Sphere Dial 343
This armillary sphere, made of steel and brass, is approximately 2 meters tall. The dial is the result of a collaboration between students from the 1997 Industrial Engineering class of the Technical University of Nova Scotia (now called DAL TECH) and a local shipbuilding firm who did the construction. The theme of industrial engineering is reflected in the cogwheel-like metal rings used in the construction. Initials of every classmate are punched into the cogs. On the plinth is the Equation of Time.

approx. 8 feet in diameter Roman numerals, with half-hour marks and compass rose. Dial sits on a rectangular stone pedestal.

The dial itself is a semicircular portion of an equatorial ring with inscribed hour lines and raised Roman numerals. The dial has been exhibited in various museums in San Diego, San Francisco, Seattle and Vancouver before permanent installation at the Bishop Museum in Honolulu.

Kennett Square Pennsylvania USA Analemmatic Dial 328
37.2 ft x 23.8 ft. This is probably the world's largest analemmatic, unusually designed to show standard time directly. It took 8 years of daily readings to perfect the sundial, which is accurate to within 2 minutes. Hour markers are bronze Roman numerals. Minute lines inscribed in limestone curbing. The gnomon itself is a moveable pole that is set on an AM or PM daily curve. NASS member P. Kenneth Seidelman was instrumental in correcting this design in 1978.
 
 
Baltimore Maryland USA Equatorial Dial 327
The dial is a partial cylinder held upright at the proper angle by four ornate pillars. The gnomon is a wire stretched between another pillar at the south edge and the mouth of an eagle mounted on another pillar at the north edge. On the wire is a bead, the shadow of which falls on the cylindrical plate. The cylindrical plate has an analemma for each daylight hour of standard time.' (McDowell) One of three known to be made in this design. Another dial of this design, once in front of the Physical Laboratory at Northwestern University, was placed at a private residence in New Hampshire in 1973, Evanston, IL.
 
 
Baltimore Maryland USA Horizontal Dial 326
'Very bad small dial on a beautiful stone pedestal. The engraving on the base states that it was erected in 1908. At some point the dial face went missing. A new dial was installed sometime before 1966. It is doubtful that the existing dial is a replica of the original. The stylistic differences between the design of the pedestal and the design of the new dial which sits atop it are apparent.' (McDowell)
 
 
Baltimore Maryland USA Horizontal Dial 325
A 12 inch diameter horizontal bronze dial. A wire is stretched from the dial's center, which is decorated as a cluster of flowers, to the beak of a bird perched on the rim of the dial plate, forming the gnomon at proper angle. The bird is apparently the 'early bird' eating the worm (gnomon). The dial plate itself has hour lines and Roman numerals from 5 am to 7 pm. Dial sits atop a cast concrete post with octagonal top.
 
 
Baltimore Maryland USA Horizontal Dial 324
