The sign, $, used in this country to signify a dollar, is supposed to date from the time of the pillar dollar in Spain. This was known as the "Piece of Eight" (meaning eight reals), the curve being a partial representation of the figure 8. The two vertical strokes are thought to represent the Pillars of Hercules, which were stamped upon the coin itself.

An Old-Time LaFrance Piston Steam Fire Engine*.

Built in 1894, at which time it had a capacity of 900 gallons per minute. This steam engine was equipped with a LaFrance boiler. This particular engine was in service in Superior, Wis., and was in continuous service pumping water on a coal fire night and day from November 18, 1913, to February 18, 1914 (just exactly three months), during which time it was only shut down twice to replace burned-out grates and three times to replace broken springs. During all of this time this steamer was incased in snow and ice.
