Your duty is unpleasant, and the duties you have already undergone have been onerous and burdensome. "It is unpleasant for a man to sit on the trial of a fellow-man on a charge involving his life and liberty, but it is your business to do that in this case. As long as human nature is constituted in such a way as it is, law will be necessary to make some men walk straight. Crimes, murders, thefts and arsons can only be prevented by the enforcement of the law. The law, as I said, can only be enforced by the jury. On the call of Providence you are here now, and your duty is before you. Recollect, gentlemen, that while your duty is serious and burdensome, it is also of vast importance. Remember, gentlemen, that your duty is just as important and as necessary, and the necessity for courage and determination to carry out that duty is as great as it would be upon the battlefield or in any other walk of life. Deal with these men justly, execute the law, satisfy your own consciences, and the rest of us will be satisfied." * * * * * COUNSELOR DONAHOE TALKS. Mr. Ingham was followed by Mr. Donahoe, who spoke in behalf of O'Sullivan and Kunze. He prefaced his argument with the remark that there was no duty in the life of a lawyer that afforded him more pleasure than to defend the innocent; and that, therefore, he began to plead for the lives of his two clients with a heart as light as that of a newly-made bride, caressed with her husband's love. It was the apparent desire of the public prosecutor to disgrace every witness, who appeared to testify to any fact or circumstance, tending to show the innocence of the accused, but this course would never deter him from exercising the best ability that God had given him, in procuring for his clients every legal right known to the law and the country. He urged the jury to banish all prejudice, and to adopt reasonable judgment in considering the legal evidence of the case and the laws of the country, and urged that if they did so, his two clients would soon be breathing the free air of heaven. The counsel drew attention to the fact, that he had been especially assigned to the defense of Kunze by the Court, the prisoner having sworn that he did not have a dollar, and also said that until the opening of the present case he had had no connection with O'Sullivan or any of his friends. There was nothing to prove, the counsel went on to argue, that Kunze was in any way connected with the crime. The young man who claimed to have seen him wash his feet at the window of the Clark street flat, as well as the saloon-keeper, whose place he was alleged to have visited on the night of May the 4th, might easily have been mistaken. It was, in brief, a case of mistaken identity. Mr.
