Mr. DIXON. Mr. President, the Nestor of the American Senate has been called from the scene where his counsels have been so often heard, and his wisdom was so justly honored. Whatever of eloquence, of learning, of skill in debate may remain in this body, the death of Judge COLLAMER leaves a void here which will not easily be supplied. Whoever aspires to fill his peculiar place, and exert a similar influence, must possess not onlyequal abilities and a character as pure, but a judgment enlightened like his by the lessons, and a mind stored with the fruits, of a long and varied experience. If, in our estimate of the dead, we are some times liable to pass beyond the me reof a just appreciation, we may be assu edthat whatever language of eulogy is applied to him, we are in little danger of exceeding a correct judgment of his merits. In the Senate, and wherever else he was called to act, he was a man so marked and peculiar that his superiority in man striking respects was at once acknowledge. It was my good fortune to know hiui somewhat intimately; 1st in the HoRep and more lately in the Senate. Vhile in both these positions he was conspicuous among the celebrated and able men with whom he was associated in public affairs, there were certain qualities, intellectual and moral, in which he was not surpassed by an of the distinguished men of his time. and, rst of all, he was a inst man. His integrity was a pervading and governing characteristic of his nature; which not only controlled his conduct, but shaped his sentiments and opinions, so that he seemed Lgifted with an unerring judgment of right an wron. enlightened by this high sense of justicc, is reasoning faculties could scarcely fail in the attainment of truth; and for him to refuse its acknowledgment or resist its sway was an impossibility. Hence it was that in those intellectual processes for which he was so distinguished, he seemed never to be contending merely for polemic victory, but rather to be illumi nating, by the light of his unclouded reason, the path which his controlling sense of justice compelled him to ursne. It was impossible to follow him in testeps of his irrefutable logic, without being struck by his crfect sin cerity, as well as by the strength o his reasoning; and the arguments by which his own mind was convinced seldom failed to convince his hearers. Thus as an advocate he compelled the assent of courts and juries to his proposbtions. But it was as a judge that he seemed in his peculiarly appropriate sphere. Here, his high sense of right and his unrivaled rear soning powers, combined to render his legal judgments almost infallible; and the suitors to whom justice was dispensed by him seldom complained even of his adverse decisions. To us our venerated and deeplylamented friend was chiefly known by his punctual and constant attendance and his faithful labors in this body, in the business and debates of which he took a leading part. Here for many years we have listened to his words of wisdom, and have, been guided by the light which be shed upon every subject which he discussed; yet I cannot recall an instance in which be exerted those great abilities, with which he was in trusted for the good of mankind, for the purposes of ostentation or self disilay. The arts of eloquence he apparently little esteemed. These, with the cos of rhetoric and the feli cities of expression, he left entirely to others, satisfying himself with a plainness of languag and often with a hoineliness of lirusc, whiceh sometimes gave an added strength to his unan swerable reasoning. In the midst however, of his closest argumentation, the flash of wit, the quaint stroke of humor, the apt and illustrative aneedote, would occasionally vary the current of thought and relieve the attention which might other mse have been wearied by the severe and exact logic to which he usually so rigidly adhered. Yor should it be forgotten that, with all his power in debate he was generous and considerate of others. I o harsh or unkind word ever escaped his lips. He seldom indulged even in repartce, passing in silence any attack, real or supposed, upon himself, and a plying his powers only to the subjectmatter of is discourse. As he was respected, so he was respect ful and courteous in debate, treating others with the some consideration and regard which all conceded to his own pure character and superior abilities. n the truest and best sense of the word Judge COLLAMER was a conservntive. To conserve, to defend, to uphold and maintain the Government, the Union, the constitution, the laws of the U.S., this was his constant effort, the missionand the labor of his life. He did not believe, however, that trueconservatisin consists in upholding ancient crror, or persisting in wrongs because they seem by the lapse of time to lhave become irremediable, or by custom and usage to have own inviolable. On the contrary, he thought t at. what is good in a Gavernment may best be defended and preserved by seeking the proper occasion to correct abuses and rectify mistakes. A genuine conservative, he a; not the blind advocate of existing evils, nor the stubborn apologist of the past. He knew when to yield to nuh void I able vicissitudes, when to favor necessary changes, when to originate improvements and suggest alterations, as well as when to resist the visionary schemes of reckless innovators. He sustained no policy merely because it was old; he favored no measure merely because it was new. I have spoken of Judge COLLAMER as he was secu in the performance of his public duties. There was another side of his character in which the persuasive advocate, the inflexible judge, the wise and politic statesman was seen in a ine re genial and winning light. In the unre strained intercourse of private life and the flow of ordinary conversation there was a charm in his society which those who knew him intimately cannot soon forget. The judge and the Senator were forgotten in the brilliant and delightful companion, the generous and sympathizing friend, the wise, the candid, the farseeing an. In the fullness of his years, after a life of usefulness and of honor, and in the assurance of a Christian hope of a blessed immortality, he has gone to his reward. Of those who survive him, of those who in coming years are to succeed him here and elsewhere there are, few who can equal him in ability and in virtue. His intellectua and his moral traits partook of the antique mold, rather than of the modern type of character. Yet though rare and peculiar, they are not inimitable, and to the noble and aspiring youth of our country, whose hearts beat high with the love of civil liberty, and who are fired with a generous ambition to benefitand exalt the human race, they furnish an example worthy of earnest emulation and full of the highest eneoura ement. They may see him in outh studious, aborious, and virtuous; in man iood excrting all his powers for the good of mankind; and in his ripened age still in the full possession of his faculties, an conscientiously performing all his duties crowned with public honors and the respect and affection of a rateful people. They may learn, also, from is life, that the greatest talents do not eclipse the higher and urer light of a truly Christian character; and ) they cannot fail to erceive the superiority of moral over intel ectual greatness, when they observe that with all his pree ininent abilities, the most striking characteristic of JACOB Counmzn was his perfect integrity.
