It would exceed the limits of this sketch to allude in detail to all the cases argued by Mr. Webster in the Supreme Court of the United States; still less would it be practicable to trace him through his labors in the State courts. We can barely mention a few of the more considerable causes. The case of Gibbons and Ogden, in 1824, is one of great celebrity. In this case the grant by the State of New York to the assignees of Fulton, of an exclusive right to navigate the rivers, harbors, and bays of New York by steam, was called in question, and was decided to be unconstitutional, after having been maintained by all the tribunals of that great and respectable State. The decision of this great case turned upon the principle, that the grant of such a monopoly of the right to enter a portion of the navigable waters of the Union was an encroachment, by the State, upon the power "to regulate commerce,"----a power reserved by the Constitution to Congress, and in its nature exclusive. The cause was argued by Messrs. Webster and Wirt for the plaintiffs, and by Messrs. Oakley and Emmett for the defendants in error,--an array of talent worthy the magnitude of the interests at stake. The decision of the court was against the monopoly. Few cases in the annals of federal jurisprudence are of equal importance; none, perhaps, was ever argued with greater ability. In the course of his discussion, Mr. Webster said, with great felicity of illustration, that, by the establishment of the Constitution, the commerce of this whole country had become a _unit_, a form of expression used with approbation by Chief Justice Marshall in delivering the opinion of the court. A very distinguished compliment was paid to Mr. Webster's argument in this case, a quarter of a century after its delivery, by Mr. Justice Wayne of the Supreme Court of the United States. On the occasion of Mr. Webster's visit to the South, in the spring of 1847, he was received with public honors, among other places, at Savannah. He was there addressed by Judge Wayne on behalf of his fellow-citizens. In the course of his remarks on that occasion, Judge Wayne alluded to Mr. Webster's line of argument in this case in the following manner:--
