The study of Natural History in the University of Upsala was, at this time, at a low ebb. It was like the Art Department in many of the American colleges: its existence largely confined to the school catalog. There were many weeks of biting poverty and neglect for Linnaeus, but he worked away in obscurity and silence and endured, saying all the time, "The sun will come out, the sun will come out!" Doctor Olaf Rudbeck had charge of the chair of Botany, but seldom sat in it. His business was medicine. He gave no lectures, but the report was that he made his students toil at cultivating in his garden--this to open up their intellectual pores. In the course of his work, Linnaeus devised a sex plan of classification, instead of the so-called natural method. He wrote out his ideas and submitted them to Rudbeck. The learned Doctor first pooh-poohed the plan, then tolerated it, and in a month claimed he had himself devised it. On the scheme being explained to others there was opposition, and Rudbeck requested Linnaeus to amplify his notes into a thesis, and read it as a lecture. This was done, and so pleased was the old man that he appointed Linnaeus his adjunctus. In the Spring of Seventeen Hundred Thirty, Linnaeus began to give weekly lectures on some topic of Natural History. Linnaeus was now fairly launched. His animation, clear thinking, handsome face and graceful ways made his lectures very popular. Science in his hands was no longer the dull and turgid thing it had before been in the University. He would give a lecture in the hall, and then invite the audience to walk with him in the woods. He seemed to know everything: birds, beetles, bugs, beasts, trees, weeds, flowers, rocks and stones were to him familiar. He showed his pupils things they had walked on all their lives and never seen. The old Botanical Garden that had degenerated into a kitchen-garden for the Commons was rearranged and furnished with many specimens gathered round about. A system of exchange was carried on with other schools, and Natural History at Upsala was fast becoming a feature. Old Doctor Rudbeck hobbled around with the classes, and when Linnaeus lectured sat in a front seat, applauding by rapping his cane on the floor and ejaculating words of encouragement. Linnaeus was now receiving invitations to lecture at other schools in the vicinity. He made excursions and reports on the Natural History of the country around. The Academy of Science of Upsala now selected him to go to Lapland and explore the resources of that country, which was then little known. The journey was to be a long and dangerous one. It meant four thousand miles of travel on foot, by sledge and on horseback, over a country that was for the most part mountainous, without roads, and peopled with semi-savages. There were two reasons why Linnaeus should make the trip: One was he had the hardihood and the fortitude to do it.
