As long as money hasexisted, the problem of counterfeit currency has too, but it became aparticular problem once printed notes went into general circulation. Ineighteenth-century North America, Benjamin Franklin – who owned a firmthat printed money for several of the colonies – hit on the idea of misspellingPennsylvania on official currency, on the grounds that forgers would spell it
correctly and the notes could easily be spotted as counterfeit, but that only went so far.

Excellent old HTML page. Photo showing man on a Lazy Board. A few topics discussed:
- evolution from the small farm wagon to the Conestoga wagon. Bowed bottom.
- Large wheels. Largest wagons between 14-16" long and pulled by 6 large horses.
- Colors often blue body, red wheels, white top.
- What equipment was carried - tool box, grease, jack for the wheels.
- Lead horse was on the front left. Driver would walk on left - thus wagons passed slower traffic on the left.
- Wheel lock chain on back wheel to keep wagon from overtaking the horses.
- Canals began to appear in the 1820's
