Mules on the Towpath of the Erie Canal
In the early 1800s, moving heavy goods across New York State was slow and costly. Roads were bumpy, and wagons got stuck in mud. So workers dug a canal, which is a waterway made by people. The Erie Canal opened in 1825. It joined the Hudson River with Lake Erie, so boats could travel a long way inland.
Most of the digging was done by hand, with shovels and with the help of horses and oxen. It took years of hard work.
A canal boat had no engine. Instead, a pair of mules or horses walked along a path beside the water, called the towpath. A long rope ran from the animals to the boat, and they pulled it along at a slow walking pace.
Sometimes the land rose uphill. To fix this, builders made locks. A lock is a small chamber with gates. Water is let in or out, and the boat rises or sinks like it is riding an elevator, until it is level with the next stretch of canal.
Shipping goods by canal cost much less than by wagon, and towns along the canal grew quickly.
