Probably during the winter of 1885-1886, Wilbur was hit with in the face with a bat while playing an ice-skating game. The injury at first did not seem serious. In the Bishop's words, "In his nineteenth year when playing a game on skates at an artificial lake at the Soldier's Home near Dayton, Ohio, a bat accidentally flew out of the hand of a young man... and struck Wilbur, knocking him down, but not injuring him much. A few weeks later, he began to be affected with nervous palpitations of the heart which precluded the realization of the former idea of his parents, of giving him a course in Yale College." For the next four years, Wilbur remained homebound, suffering perhaps as much from depression as from his vaguely-defined heart disorder. During this period, Wilbur cared for his mother Susan, who was dying from tuberculosis.
