Mules played a vital role in the construction and operation of the C&O Canal in the 1800’s. In an age before highways and planes, mules were the “engines” of the boats that traveled along the canal waterway, hauling goods and people between Georgetown and Cumberland. Mules were suited to pull boats along the 184.5 miles of the canal because of their strength, intelligence, and easy-going temperament. ![]() NPS Photo / E. Cowan What Is a Mule?Mules are a perfect example of the hybrid principle: crossing two species to produce a third, often better, species more suited for certain conditions or work. Crossing a female horse (a mare) with a male donkey (a jack) produces a mule. George Washington had ambitions of breeding an "excellent race of mules" in North America. He mated his prize mares with donkeys at Mount Vernon and introduced a powerful breed of mules to the continent. "I enjoyed being with the mules. I had a lot of fun with the mules. A mule is intelligent. He has more intelligence than a horse. And good. Gentle. If you treat a mule right, he’ll treat you right." Learn MoreDiscover the world of mules.
