believe it helps to save the Union, and what I forbear, I forbear because I do not believe it would help to save the Union." [Footnote: Letter to Horace Greeley, August 22, 1862.] And when he had freed the negro by a proclamation that violated the letter of the Constitution, it was still that boy of the woods speaking in the man--the boy who had learned his lesson beyond all possibility of forgetting or misunderstanding--"I felt that measures otherwise unconstitutional might become lawful by becoming indispensable to the preservation of the Constitution through the preservation of the nation." It was from those shingles that he learned, too, the place of the State in this nationalism. Its paternalism has grown tremendously since 1824, when democracy was a negative, a repressive and not a positive, aggressive political and social spirit, but, as it was, it gave him the foundation of the political structure within whose lines he had to build later. And with all this was a self-discipline in the two great knowledges by which men have climbed from savages to gods--language and mathematics. He was told one day that there was an English grammar in a house six miles from his home, and he at once walked off to borrow it. And he studied geometry and algebra alone. This may seem to you an inconsequential thing, but having myself on those same prairies not far away from the Sangamon acquired my algebra with little teaching and my solid geometry with only the tuition of a book and of the sun or a lamp, I am able to appreciate what the hardship of that self-schooling was. It was more agreeable to watch the clouds while the horses rested at the end of the furrow, to address, as did Burns, lines to a field-mouse, or to listen to the song of the meadow-lark, than to learn the habits of the three dimensions then known, of points in motion, of lines in intersection, of surfaces in revolution, or to represent the unknown by algebraic instead of poetic symbols.
