In the letter to Stuart which we have quoted, Lincoln announced his intention to form a partnership with Judge Logan, which was soon carried out. His connection with Stuart was formally dissolved in April, 1841, and one with Logan formed which continued for four years. It may almost be said that Lincoln's practice as a lawyer begins from this time. Stuart, though even then giving promise of the distinction at which he arrived in his profession later in life, was at that period so entirely devoted to politics that the business of the office was altogether a secondary matter to him; and Lincoln, although no longer in his first youth, being then thirty-two years of age, had not yet formed those habits of close application which are indispensable to permanent success at the bar. He was not behind the greater part of his contemporaries in this respect. Among all the lawyers of the circuit who were then, or who afterwards became, eminent practitioners, [Footnote: They were Dan Stone, Jesse B. Thomas, Cyrus Walker, Schuyler Strong, Albert T. Bledsoe, George Forquer, Samuel H. Treat, Ninian W. Edwards, Josiah Lamborn, John J. Hardin, Edward D. Baker, and others.] there were few indeed who in those days applied themselves with any degree of persistency to the close study of legal principles. One of these few was Stephen T. Logan. He was more or less a politician, as were all his compeers at the bar, but he was always more a lawyer than anything else. He had that love for his profession which it jealously exacts as a condition of succeeding. He possessed few books, and it used to be said of him long afterwards that he carried his library in his hat. But the books which he had he never ceased to read and ponder, and we heard him say when he was sixty years old, that once every year since he came of age he had read "Blackstone's Commentaries" through. He had that old-fashioned, lawyer-like morality which was keenly intolerant of any laxity or slovenliness of mind or character. His former partner had been Edward D. Baker, but this brilliant and mercurial spirit was not congenial to Logan; Baker's carelessness in money matters was Intolerable to him, and he was glad to escape from an associate so gifted and so exasperating. [Footnote: Logan's office was, in fact, a nursery of statesmen. Three of his partners, William L. May, Baker, and Lincoln, left him in rapid succession to go to Congress, and finally the contagion gained the head of the firm, and the judge was himself the candidate of his party, when it was no longer able to elect one. After he had retired from practice, the office, under his son-in-law and successor, Milton Hay, retained its prestige for cradling public men. John M. Palmer and Shelby M. Cullom left it to be Governors of the State, and the latter to be a Congressman and Senator.]
