Although I had met the Academic board and come off with fair success, yet I knew so little of Algebra or any of the higher branches of mathematics that during my first six months at the Academy I was discouraged by many misgivings as to the future, for I speedily learned that at the January examination the class would have to stand a test much severer than that which had been applied to it on entering. I resolved to try hard, however, and, besides, good fortune gave me for a room-mate a Cadet whose education was more advanced than mine, and whose studious habits and willingness to aid others benefited me immensely. This room-mate was Henry W. Slocum, since so signally distinguished in both military and civil capacities as to win for his name a proud place in the annals of his country. After taps--that is, when by the regulations of the Academy all the lights were supposed to be extinguished, and everybody in bed--Slocum and I would hang a blanket over the one window of our room and continue our studies--he guiding me around scores of stumbling-blocks in Algebra and elucidating many knotty points in other branches of the course with which I was unfamiliar. On account of this association I went up before the Board in January with less uneasiness than otherwise would have been the case, and passed the examination fairly well. When it was over, a self-confidence in my capacity was established that had not existed hitherto, and at each succeeding examination I gained a little in order of merit till my furlough summer came round--that is, when I was half through the four-year course. My furlough in July and August, 1850, was spent at my home in Ohio, with the exception of a visit or two to other Cadets on furlough in the State, and at the close of my leave I returned to the Academy in the full expectation of graduating with my class in 1852.
