After the turmoil of his school and university life there now succeeded a period of quiet teaching and literary labors, during which the man gathered himself together, formed those settled convictions which were the mainspring of his future career, and gave evidence of his underlying strength and soundness of character. For two years he was a private tutor, in Neubrandenburg until the end of September, 1804, and then at the Torgelow glass-works, twenty-five miles westward. The first of these years witnessed a foreshadowing of the great work begun seven years later in Berlin. Every evening he gave his pupils, the sons of Baron Lefort, instruction in swimming, in a brook near the town, followed by practice in running, climbing, jumping, and wrestling on a neighboring height, and by a few lively games. Any other boys who happened to be present, although strangers to him and with no claim upon his services, were made welcome, and in this way the number was increased to twenty or thirty. New and equally vigorous outdoor exercises were substituted in the late fall and winter months. On October 1, 1805, Jahn took public leave of his Mecklenburg friends through the columns of the _Strelitz’scher Anzeiger_. His next move, made in the interest of literary plans and to favor his own advancement, was to Göttingen. Some months were spent in linguistic studies at the University, and in the summer of 1806 he removed to Jena, where he completed a volume of “Contributions to High German Synonymy,” embodying material collected in all parts of Germany during the excursions of his university days. The book is the work of an ardent friend of the German language, and not of a scientific philologist; and it reveals the keen observer of the country and its inhabitants, as well as the student of popular dialects.
