Cabin John in Montgomery County, Maryland — The American Northeast (Mid-Atlantic)
Stone for the Seven Locks (locks 7 through 14) was cut and finished by stonemasons who were paid by the "piece." Arrows, pine trees, hourglasses, and other signs marked their work for the paymaster. Some of their marks can still be seen in the lock masonry.
The lock chamber was filled or emptied by opening small butterfly gates — called "paddles" — at the bottom of each wooden lock gate. This was done by turning long metal rods, or "stems." Boats going up canal to Cumberland entered the lower level and were lifted eight feet. Boats going down entered a filled lock chamber and were slowly lowered, a job that took about ten minutes.
