A peculiarly interesting episode of Lincoln's life belongs to this period, though unrelated to political events. This was the meeting, in a professional way, with Edwin M. Stanton, at that time a prominent lawyer of Pittsburgh, afterwards the great War Secretary of President Lincoln's cabinet. The circumstances were briefly these: Among Lincoln's law cases was one connected with the patent of the McCormick Reaper; and in the summer of 1857 he visited Cincinnati to argue the case before Judge McLean of the United States Circuit Court. It was a case of great importance, involving the foundation patent of the machine which was destined to revolutionize the harvesting of grain. Reverdy Johnson was on one side of the case, and E.M. Stanton and George Harding on the other. It became necessary, in addition, to have a lawyer who was a resident of Illinois; and inquiry was made of Hon. E.B. Washburne, then in Congress, as to whether he knew a suitable man. The latter replied that "there was a man named Lincoln at Springfield, who had considerable reputation in the State." Lincoln was retained in the case, and came on to Cincinnati with a brief. Stanton and Harding saw in their associate counsel "a tall, dark, uncouth man, who did not strike them as of any account, and, indeed, they gave him hardly any chance." An interesting account of this visit, and of various incidents connected with it, has been prepared by the Hon. W.M. Dickson of Cincinnati. "Mr. Lincoln came to the city," says Mr. Dickson, "a few days before the argument took place, and remained during his stay at the house of a friend. The case was one of large importance pecuniarily, and in the law questions involved. Reverdy Johnson represented the plaintiff. Mr. Lincoln had prepared himself with the greatest care; his ambition was to speak in the case, and to measure swords with the renowned lawyer from Baltimore. It was understood between his client and himself, before his coming, that Mr. Harding of Philadelphia was to be associated with him in the case, and was to make the 'mechanical argument.' Mr. Lincoln was a little surprised and annoyed after reaching Cincinnati, to learn that his client had also associated with him Mr. Edwin M. Stanton, of Pittsburgh, and a lawyer of our own bar; the reason assigned being that the importance of the case required a man of the experience and power of Mr. Stanton to meet Mr. Johnson. The reasons given did not remove the slight conveyed in the employment, without consultation with Lincoln, of this additional counsel. He keenly felt it, but acquiesced. The trial of the case came on; the counsel for defense met each morning for consultation. On one of these occasions one of the counsel moved that only two of them should speak in the case. This motion was also acquiesced in. It had always been understood that Mr. Harding was to speak to explain the mechanism of the reapers. So this motion excluded either Mr. Lincoln or Mr. Stanton.
