"The Lee family living in the home in Lexington as I knew them consisted of General and Mrs. Lee, their son, George Washington Custis, who succeeded his father as President of the College, and three daughters, Mary, Agnes, and Mildred. Agnes was an invalid and was away from home on health trips most of the time and I saw very little of her. The oldest daughter, Mary, was a person of strong, but somewhat eccentric character. She was wholly devoid of fear and was fond of taking long walks in the country alone."

The same gentleman then goes on to relate a characteristic incident. On one of her walks, on the road leading to House Mountain, Miss Mary came upon a man, bringing a load of apples to town, who was savagely beating his horse, which seemed unable to pull the wagon out of a mudhole. Miss Mary walked up to him, demanding that he stop beating the horse, and promising to show him how to get out of the hole. This she did. Later she induced some of the workers in church and Sunday-school to look him up. Under their influence he reformed his habits, came to church with his family, and became an upstanding member of the community.
