the next chapter relate the course of the journey which was begun on that day. [TO BE CONTINUED.] ------ Abridged from Le Correspondant. THE MARQUIS DE CHASTELLUX. In the bleak region of Upper Burgundy, not far from the domain of Vauban, stands the old manor of Chastellux, famous since the fifteenth century as the birth-place of two brothers, one of whom became an admiral, the other a marshal of France. From this feudal stronghold came forth one of the most amiable of the courtiers of Louis XVI.--a disciple of Voltaire and Hume, a rival of Turgot and Adam Smith, a friend of Washington and Jefferson, a forerunner of the revolutionists of 1789, a philosopher, an historian, a political economist, something of a poet, something of a naturalist, something of an artist, a man of taste, an enthusiastic student, a brilliant talker, and an elegant writer. The rude Sieurs de Chastellux would have been not a little astonished could they have foreseen what character of man was destined to inherit their title. François Jean de Beauvoir, first known as Chevalier and afterward Marquis de Chastellux, was born at Paris in 1734. He was a son of the Count de Chastellux, lieutenant-general of the armies of the king, by Mlle. d'Aguesseau, daughter of the chancellor. His mother, being left a widow at an early period, withdrew thereupon into the privacy of domestic life, and the young marquis had the good fortune to be brought up under the eyes of the Chancellor d'Aguesseau himself. He entered the army at sixteen, and was hardly twenty-one before he had risen to be colonel. He distinguished himself highly during the campaigns of the Seven Years' War, and it was as a reward of his gallantry no less than out of compliment to his hereditary rank that he was selected on one occasion to present to the king the flags of a conquered city. It is hard to understand how, in the midst of such an active life, he could find time for study; but for all that he knew Greek, Latin, English, and Italian, and had some acquaintance with every branch of science cultivated in his time. From boyhood he showed a zealous interest in every sort of invention or discovery which promised to be of practical use {182} to mankind. When the principle of inoculation for small-pox was first broached in Europe, everybody shrank in alarm from the experiment. The young marquis had himself inoculated without his mother's knowledge, and then, running to Buffon, who knew his family, exclaimed joyfully, "I am saved, and my example will be the means of saving many others."
