Notation on some ancient maps

As we muse on the ways in which the map is not the territory, we might recall that it was on this date in 1870 that America’s first asphalt pavement was laid in front of City Hall in Newark, N.J.  Edmund J. DeSmedt, the Belgian chemist who oversaw the work, had received a U.S. patent for this asphalt paving method two months earlier. Later that year, DeSmedt became the inspector of asphalt and cements for the District of Columbia, and oversaw wide application there.
