Being at Oberlin a few years since, and learning that a suit was to be tried before a justice of the peace, in which Langston was counsel for the defence, I attended. Two white lawyers--one from Elyria, the other residing at Oberlin--were for the plaintiff. One day was consumed in the examination and cross-questioning of witnesses, in which the colored lawyer showed himself more than a match for his antagonists. The plaintiff's counsel moved an adjournment to the next day. The following morning the court room was full before the arrival of the presiding justice, and much interest was manifested on both sides. Langston's oratory was a model for the students at the college, and all who could leave their studies or recitations were present. When the trial commenced, it was observed that the plaintiffs had introduced a third lawyer on their side. This was an exhibition of weakness on their part, and proved the power of the "black lawyer," who stood single-handed and alone. The pleading commenced, and consumed the forenoon; the plaintiff only being heard. An adjournment for an hour occurred, and then began one of the most powerful addresses that I had heard for a long time. In vigor of thought, in imagery of style, in logical connection, in vehemence, in depth, in point, and in beauty of language, Langston surpassed his opponents, won the admiration of the jury and the audience, and, what is still better for his credit, he gained the suit. Mr. Langston's practice extends to Columbus, the capital of the state, and in the county towns, within fifty miles of his home, he is considered the most successful man at the bar. An accomplished scholar and a good student, he displays in his speeches an amount of literary acquirements not often found in the mere business lawyer. When pleading he speaks like a man under oath, though without any starched formality of expression. The test of his success is the permanent impression which his speeches leave on the memory. They do not pass away with the excitement of the moment, but remain in the mind, with the lively colors and true proportions of the scenes which they represent. Mr. Langston is of medium size and of good figure, high and well-formed forehead, eyes full, but not prominent, mild and amiable countenance, modest deportment, strong, musical voice, and wears the air of a gentleman. He is highly respected by men of the legal profession throughout the state. He is a vigorous writer, and in the political campaigns, contributes both with speech and pen to the liberal cause. Few men in the south-west have held the black man's standard higher than John Mercer Langston. WILLIAM C. NELL.
