The third and last journey of M. de Chastellux led him through New Hampshire, Massachusetts, and northern Pennsylvania. This was during the months of November and December, 1782, on the eve of his return to France. He started from Hartford, the capital of Connecticut, and, after visiting several other places, went to Boston, for he could not leave America without seeing this city, the cradle of the revolution. He found at this port the French fleet, under command of M. de Vaudreuil, which was to carry back the expeditionary corps to France. He closes his _Journal_ with an interesting account of the university at Cambridge, which Ampère, who was, like him, a member of the French Academy, visited and described seventy years afterward. In the appendix to his book he gives a letter written by himself on board the frigate _l'Émeraude_, just before sailing, to Mr. Madison, professor of philosophy in William and Mary College. It is upon a subject which has not yet lost its appropriateness--the future of the arts and sciences in America. A democratic and commercial society, always in a ferment, seemed to him hardly compatible with scientific, and still less with artistic, progress. But, in his solicitude for the welfare of the country he had been defending, he would not allow that the difficulty was insuperable. Some of his remarks upon this subject are extremely delicate and ingenious. The question which troubled him is not yet fully answered, but it is in a fair way of being settled. The United States have really made but little progress in the arts, though they have produced a few pictures and statues which have elicited admiration even in Europe at recent industrial exhibitions. They are beginning, however, to have a literature. Even in the days of the revolution they could boast of the writings of Franklin, which combined the-most charming originality with refinement and solid good sense. Now they can show, among novelists, Fenimore Cooper and the celebrated Mrs. Beecher Stowe, whose book gave the signal for another revolution; among story-tellers, Washington Irving and Hawthorne; among critics, Ticknor; among historians, Prescott and Bancroft; among economists, Carey; among political writers, Everett; among moralists, Emerson and Channing; among poets, Bryant and Longfellow. In science they have done still more. They have adopted and naturalized one of the first of modern geologists, Agassiz; and the hydrographical labors of Maury, [late] director of the Washington Observatory, are the admiration of the whole world. Their immense development in industrial pursuits implies a corresponding progress in practical science. It was Fulton, an American, who invented the steamboat, and carried out in his own country the idea which he could not persuade Europe to listen to; and only lately the reaping-machine has come to us from the shores of the great lakes and the vast prairies of the Far West.
