Linnaeus was a businessman as well as a naturalist. It would require a book to tell of the glorious half-gypsy life of these eight young men, moving slowly through woods, across plains, over mountains and meadows, studying soil, rocks, birds, trees and flowers, collecting and making records. Camping at night by flowing streams, awakening with the dawn and cooking breakfast by the campfire in a silence that took up their shouts of laughter in surprise, and echoed them back from the neighboring hills! At last the journey was ended. Linnaeus had proved his ability to teach--his animation, good-cheer and friendly qualities brought his pupils very close to him. Reuterholm insisted that he should attach himself to the rising little college at Fahlun. There he met Doctor Moraeus, a man of much worth in a scientific way. At his house Linnaeus made his home. There was a daughter in the household, Sara Elizabeth, tall, slender, appreciative and studious. One of the Reuterholms had courted her, but in vain. There were the usual results, and when Carolus and Sara Elizabeth came to Doctor Moraeus hand in hand for his blessing, he granted it as good men always do. Then the Doctor gave Linnaeus some good advice--go to Holland or somewhere and get a doctor's degree. The enemies at Upsala called Linnaeus "the gypsy scientist." Silence them--Linnaeus was now a great man, and the world would yet acknowledge it. Sara Elizabeth agreed in all of the propositions. Love, they say, is blind, but sometimes love is a regular telescope. This time love saw things that the learned men of Upsala failed to discover--their diagnosis was wrong. Linnaeus had prepared a thesis on intermittent fever, and he was assured that if he presented this thesis at the medical school at Harderwijk, Holland, with letters from Baron Reuterholm and Doctor Moraeus, it would secure him the much desired M.D. A few months, at most, would suffice. He could then return to Fahlun and take his place as a practising physician and a professor in the college, marry the lady of his choice and live happy ever afterward. So he started away southward. In due time, he arrived at Harderwijk and read his thesis to the faculty. Instead of the callow youth, such as they usually dealt with, they found a practised speaker who defended his points with grace and confidence. The degree was at once voted, and a "cum laude" thrown in for good measure. Linnaeus was asked to remain there and give a course of lectures on natural history. This he did. Before going home he thought he would take a little look in on Leyden, at that time the bookmaking and literary center of the world. At Leyden he met Gronovius, the naturalist, who asked him to remain and give lectures at the University. He did so, and incidentally showed Gronovius the manuscript of his book on the new system of botanic classification.
