My service with Mr. Hay was a distinct advance upon the cotton factory, and I also made the acquaintance of an employer who was very kind to me. Mr. Hay kept his books in single entry, and I was able to handle them for him; but hearing that all great firms kept their books in double entry, and after talking over the matter with my companions, John Phipps, Thomas N. Miller, and William Cowley, we all determined to attend night school during the winter and learn the larger system. So the four of us went to a Mr. Williams in Pittsburgh and learned double-entry bookkeeping. One evening, early in 1850, when I returned home from work, I was told that Mr. David Brooks, manager of the telegraph office, had asked my Uncle Hogan if he knew where a good boy could be found to act as messenger. Mr. Brooks and my uncle were enthusiastic draught-players, and it was over a game of draughts that this important inquiry was made. Upon such trifles do the most momentous consequences hang. A word, a look, an accent, may affect the destiny not only of individuals, but of nations. He is a bold man who calls anything a trifle. Who was it who, being advised to disregard trifles, said he always would if any one could tell him what a trifle was? The young should remember that upon trifles the best gifts of the gods often hang. My uncle mentioned my name, and said he would see whether I would take the position. I remember so well the family council that was held. Of course I was wild with delight. No bird that ever was confined in a cage longed for freedom more than I. Mother favored, but father was disposed to deny my wish. It would prove too much for me, he said; I was too young and too small. For the two dollars and a half per week offered it was evident that a much larger boy was expected. Late at night I might be required to run out into the country with a telegram, and there would be dangers to encounter. Upon the whole my father said that it was best that I should remain where I was. He subsequently withdrew his objection, so far as to give me leave to try, and I believe he went to Mr. Hay and consulted with him. Mr. Hay thought it would be for my advantage, and although, as he said, it would be an inconvenience to him, still he advised that I should try, and if I failed he was kind enough to say that my old place would be open for me.
