In the summer of 1857 Lincoln was employed by Mr. Manny, of Rockford, Ill., to defend him in an action brought by McCormick,* who was one of the inventors of the reaping machine, for infringement of patent. Lincoln had been recommended to Manny by E. B. Washburne, then a member of Congress from northern Illinois. The case was to be tried before Judge McLean at Cincinnati, in the Circuit Court of the United States. The counsel for McCormick was Reverdy Johnson. Edwin M. Stanton and George Harding, of Philadelphia, were associated on the other side with Lincoln. The latter came to Cincinnati a few days before the argument took place, and stopped at the house of a friend. "The case was one of great importance pecuniarily," relates a lawyer** in Cincinnati, who was a member of the bar at the time, "and in the law questions involved. Reverdy Johnson represented the plaintiff. Mr. Lincoln had prepared himself with the greatest care; his ambition was up 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.' * The case, McCormick vs. Manny, is reported in 6 McLean's Rep., P. 539. ** W. M. Dickson. After reaching Cincinnati, Mr. Lincoln was a little surprised and annoyed to learn that his client had also associated with him Mr. Edwin M. Stanton, of Pittsburg, 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 Cincinnati lawyer was appointed for his 'local influence.' These reasons did not remove the slight conveyed in the employment without consultation with him 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 matter 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,--which? By the custom of the bar, as between counsel of equal standing, and in the absence of any action of the client, the original counsel speaks. By this rule Mr. Lincoln had precedence. Mr. Stanton suggested to Mr. Lincoln to make the speech. Mr. Lincoln answered, 'No, you speak.' Mr. Stanton replied, 'I will,' and taking up his hat, said he would go and make preparation. Mr. Lincoln acquiesced in this, but was greatly grieved and mortified; he took but little more interest in the case, though remaining until the conclusion of the trial. He seemed to be greatly depressed, and gave evidence of that tendency to melancholy which so marked his character. His parting on leaving the city cannot be forgotten.
