When, in 1715, Swedenborg returned from his first journey abroad, he was a man of twenty-seven without an occupation. While at home in Brunsbo he made excursions in the neighborhood, curiously examining the phenomena of nature: soils, clays, springs, etc. He visited the neighboring mountain Kinnekulle with the idea of selecting a site for an observatory by which to supply the facts needed to establish his discovery as to finding the longitude. But he remained without an occupation. His thoughts then turned to a professorship. He even made formal application to Upsala University that he might be kept in mind in case of a vacancy. But before the Upsala authorities came to consider his letter, all thoughts of a professorship had left him, for in 1716 he was appointed by Charles XII as Assessor Extraordinary in the College of Mines, but temporarily assigned as Polhem’s assistant in the building of the dry dock and the extension of the Gothenburg Canal from Trollhätten to Stockholm, and in the work of establishing bineries in Sweden.
