The orator then proceeded to say that this was the first centennial celebration in which he had taken part; he therefore hoped that any shortcoming might be overlooked in consideration of his quick going. He remarked that he came from where the Mississippi wound her silvery length through rich green fields, by thriving towns and mighty cities; that he was a native of the Sunny South, those happy realms where nightingales tuned harmonious song and alligators sported in their lukewarm baths. He mentioned that this was a great country, that the sun rose in the East and set in the West, and that while the snow-flakes fell and whitened all the northern plains, the orange bloomed and gentle breezes blessed the southern groves. “We are but travellers here,” said he, pathetically, “and while we breathe the air and walk upon the earth, we have two duties which should command the energies of our minds, the strength of our arms, and the honor of our souls;--one, to our fathers, those who have gone before--the other to our children, those who have already come and those yet to come after.” Mr. Lamar did not exempt bachelors from the latter of these duties, but in eloquent language urged upon all the great mission of an American citizen. The orator continued for three hours, and ’twas only when darkness fell and the chambermaid came in to light the gas, that he concluded; telling his spell-bound listeners, that, although he had much more to say, he would remember his promise to be brief, and postpone the remainder of his address until the next centennial, hoping that in the mean time they would ponder well upon the truths which he had uttered. General Sherman here nudged the President, who had fallen into a gentle spell-bound doze, and who, awakening with a start, rose and said:-- “And now, by virtue of authority in me vested, I, Ulysses S. Grant, President of the United States of America, do declare this Exhibition open for the transaction of all such business as may be legally brought before it.--Amen.” The musical fraction ended up with Beethoven’s Twelfth Mass, and “Little Brown Jug” for _encore_, and thus was the INTERNATIONAL EXPOSITION inaugurated. Through the courtesy of the Centennial Managers, we were supplied with copies of several odes, poems, essays, etc., forwarded to the committee by various distinguished authors of this and other countries, and rejected for reasons best known to the committee. Of these we cannot refrain from inserting a contribution from Lord Alfred Tennyson. It is in the shape of a two-act drama, entitled “GEORGE W. WASHINGTON.” [CLARA’S NEXT ROLE.] It has been pronounced by competent judges to be equal to much that Shakspeare did not write. It has been translated into the celestial tongue, and will be produced during the next century at the Theatre Royal, Hong Kong. We understand that Miss Clara Morris is studying the _role_ of G. W. Washington. ACT FIRST.
