1. The Locks Marker
Inscription.  
A lock acts as a step in the canal, allowing boats to be raised or lowered over changes in elevation. 29 lift locks along the Susquehanna and Tidewater Canal raised boats a total of 231 feet from Havre de Grace, Maryland, to Wrightsville, Pennsylvania.

This lock, No. 15, raised and lowered boats almost 9 feet. The double lock chamber allowed tandem boats (two boats tied together and pulled by one team) to pass through.

How the Locks Worked
1. A team of horses or mules pulled the boat along the canal. A state speed of 4 miles per hour prevented a boat's wake from damaging the edges of the canal.

The driver walked the towpath with the team and the steersman on board the boat manned the tiller. As they approached the lock, the steersman sounded a conch shell horn to alert the lock tender.

2. The team pulled the boat into the lock chamber and the lock tender closed the gate behind them. Then, the lock tender opened the wickets in the downstream gate, allowing water to flow out of the chamber.

3 The boat was lowered as the level of water in the lock chamber subsided. The boat outline in the canal shows a full-sized

"ghost" of a boat in this position.

5. The lock tender opened the downstream gate, allowing the boat to continue south. For boats heading up the canal, the process was reversed. Lowering a boat took about five minutes and raising boats took a little longer, but a boat could still be "locked through" every eight minutes.

The lock tender's job must have kept him busy - in 1855 alone, for example, more than 5,700 boats passed through the Susquehanna and Tidewater Canal on their way south.
