In 1866, Muir returned to the US after two years in Canada and got a job in a carriage plant in Indianapolis, Indiana. A year later an accident pierced his right eye, as recounted in this April 6, 1867 letter to Jeanne Carr. Though he recovered his eyesight fully in a month, he later wrote in his autobiography, "I bade adieu to all my mechanical inventions, determined to devote the rest of my life to the study of the inventions of God."
