is probable that Rousseau, when he attempted in his youth to give lessons in music, not knowing any thing whatever of music, was scarcely less fitted for the task of instruction, than St. Pierre with all his mathematical knowledge. The pressure of poverty drove him to Holland. He was well received at Amsterdam, by a French refugee named Mustel, who edited a popular journal there, and who procured him employment, with handsome remuneration. St. Pierre did not, however, remain long satisfied with this quiet mode of existence. Allured by the encouraging reception given by Catherine II. to foreigners, he set out for St. Petersburg. Here, until he obtained the protection of the Marechal de Munich, and the friendship of Duval, he had again to contend with poverty. The latter generously opened to him his purse and by the Marechal he was introduced to Villebois, the Grand Master of Artillery, and by him presented to the Empress. St. Pierre was so handsome, that by some of his friends it was supposed, perhaps, too, hoped, that he would supersede Orloff in the favor of Catherine. But more honourable illusions, though they were but illusions, occupied his own mind. He neither sought nor wished to captivate the Empress. His ambition was to establish a republic on the shores of the lake Aral, of which in imitation of Plato or Rousseau, he was to be the legislator. Pre-occupied with the reformation of despotism, he did not sufficiently look into his own heart, or seek to avoid a repetition of the same errors that had already changed friends into enemies, and been such a terrible barrier to his success in life. His mind was already morbid, and in fancying that others did not understand him, he forgot that he did not understand others. The Empress, with the rank of captain, bestowed on him a grant of fifteen hundred francs; but when General Dubosquet proposed to take him with him to examine the military position of Finland, his only anxiety seemed to be to return to France: still he went to Finland; and his own notes of his occupations and experiments on that expedition prove, that he gave himself up in all diligence to considerations of attack and defence. He, who loved Nature so intently, seems only to have seen in the extensive and majestic forests of the north, a theatre of war. In this instance, he appears to have stifled every emotion of admiration, and to have beheld, alike, cities and countries in his character of military surveyor. On his return to St. Petersburg, he found his protector
