He never was guilty of Lord Brougham's weakness of seeking to prove himself master of universal knowledge.

In delivering an address on science and invention, there was a strong temptation to an orator like Mr.Webster to substitute glittering rhetoric for real knowledge; but the address at the Mechanics' Institute is simply the speech of a very eloquent and a liberally educated man upon a subject with which he had only the most general acquaintance.
The other orations of this class were those on "The Character of Washington," the second Bunker Hill address, "The Landing at Plymouth," delivered in New York at the dinner of the Pilgrim Society, the remarks on the death of Judge Story and of Mr.Mason, and finally the speech on laying the corner-stone for the addition to the Capitol, in 1851.

These were all comparatively brief speeches, with the exception of that at Bunker Hill, which, although very fine, was perceptibly inferior to his first effort when the corner-stone of the monument was laid.

The address on the character of Washington, to an American the most dangerous of great and well-worn topics, is of a high order of eloquence.

The theme appealed to Mr.Webster strongly and brought out his best powers, which were peculiarly fitted to do justice to the noble, massive, and dignified character of the subject.
