Mcadam

In some places the McAdam was cut through a hill, while in others it crossed a valley - the surface of the road being from 12 to 15 & sometimes more feet above the old ground.

The street was to be graded, its sidewalks curbed and flagged, and the road-bed covered with McAdam.

On St. Martin Street 3 laborers and a pipe-layer were for 5 days each digging an excavation about 100 feet long (where the McAdam was very thick and, of course, hard frozen) to find a leak in the main pipe, and the appearance of the leak proved to be about 100 feet from where the leak really was, and then the main pipe was found to be broken across.

Leonardo Da Vinci drew a comprehensive sketch of a bicycle three hundred years before it was re-invented and actually placed in the hands of consumers. Imagine where we would be if the citizens of the early Renaissance had had this invention! (First, they’d need to pave all the roads with a brick or McAdam surface, and invent rubber for the tires.)
