At the opening of the Court on Thursday, the court room was crowded. The interest in the case was general, and the character of the facts, and principal witnesses for the defense, was such as appealed powerfully to the memories and early associations of the people, and there was an earnest desire to hear the speech of the young advocate, whose management of the case had so far, won for him the heartiest admiration. When the jury had answered to their names, "Mr. Ridgeley, proceed with your argument," said Judge Humphrey. The young man rose, bowed to the Court and jury, and stood silent a moment, with his eyes cast down, and it was at first thought on his rising for his speech, that he was laboring under embarrassment. When he raised his eyes, however, embarrassed as he certainly was, and commenced with a low sweet voice, it was discovered that his faltering was due mainly to the emotions of sensibility. Nature had been liberal in bestowing many of the qualifications of a great advocate upon him. He had a strong compelling will, when he chose to exercise it, which in the conflicts of the bar often prevails, and courage of a chivalrous cast, which throws a man impetuously and audaciously upon strong points, and enables him to gain a footing by the boldness and force of his onset. Barton was one to lead a forlorn hope, or defend a pass single handed, against a host. Without something of this quality, a great advocate is impossible. With a warm, poetic imagination, Nature had given him quick perceptive powers, and the faculty of expressing his thoughts without apparent effort, in simple, strong language, as well defined, and sharply cut as a cameo. Beyond this, and better than all, was a tender, sympathetic sensibility; which, if it sometimes overmastered him, made him the master of others. The commonest things in his hands took the motion and color of living things. It was not the mere sensuous magnetism of powerful physical nature; but it excited the higher intellectual sympathies, which in turn awoke and captivated the reasoning and reflective organs, that found themselves delightfully conducted along a natural and logical course, that led them unconsciously to inevitable conclusions and convictions, ere the danger was perceived, or an alarm was sounded. On the present occasion, he had not been on his feet five minutes ere it was felt that a real power, of an unusual order, was manifesting itself.
