There was a break in the home teaching in 1820.  James Mill, after bearing bravely with his early difficulties, had acquired so much renown by his famous “History of India,” that, in spite of its adverse criticisms of the East-India Company, the directors of the Company in 1817 honorably bestowed upon him a post in the India House, where he steadily and rapidly rose to a position which enabled him to pass the later years of his life in more comfort than had hitherto been within his reach.  The new employment, however, interfered with his other occupation as instructor to his boy; and for this reason, as well probably as for others tending to his advancement, the lad was, in the summer of 1820, sent to France for a year and a half.  For several months he lived in Paris, in the house of Jean Baptiste Say, the political economist.  The rest of his time was passed in the company of Sir Samuel Bentham, Jeremy Bentham’s brother.  Early in 1822, before he was eighteen, he returned to London, soon to enter the India Office as a clerk in the department of which his father was chief.  In that office he remained for five and thirty years, acquitting himself with great ability, and gradually rising to the most responsible position that could be there held by a subordinate.

But, though he was thus early started in life as a city clerk, his self-training and his education by his father were by no means abandoned.  The ancient and modern languages, as well as the various branches of philosophy and philosophical thought in which he was afterwards to attain such eminence, were studied by him in the early mornings, under the guidance of his father, before going down to pass his days in the India Office.  During the summer evenings, and on such holidays as he could get, he began those pedestrian exploits for which he afterwards became famous, and in which his main pleasure appears to have consisted in collecting plants and flowers in aid of the botanical studies that were his favorite pastime, and something more than a pastime, all through his life.  His first printed writings are said to have been on botany, in the shape of some articles contributed to a scientific journal while he was still in his teens, and it is probable, that, could they now be detected, we should find in other periodicals traces of his work, at nearly if not quite as early a period in other lines of study.  That he worked early and with wonderful ability in at least one very deep line, appears from the fact that while he was still only a lad, Jeremy Bentham intrusted to him the preparation for the press, and the supplementary annotation, of his “Rationale of Judicial Evidence.”  That work, for which he was highly commended by its author, published in 1827, contains the first publicly acknowledged literary work of John Stuart Mill.
