Scarcely had he begun this valuable labor, when the envy of one of the professors became as hard to bear as his previous poverty, and, through friends, he obtained an appointment to study the natural history of Lapland. It was a hazardous expedition for a young man of twenty-five. Now he climbed steep rocks, "which," he says, "broke loose from a spot which my late guide had just passed, and fell exactly where I had been, with such force that it struck fire as it went." Once, when floating down a river, the raft parted in the middle, and he narrowly escaped drowning. "All my food," he says, "in those fatiguing excursions, consisted, for the most part, of fish and reindeer's milk. Bread, salt, and what is found everywhere else, did but seldom recreate my palate." He travelled nearly four thousand miles, mostly on foot, often through bogs and marshes, with the water to his knees, yet always cheerful, always enthusiastic. On presenting his report to the University, on his return home, they gave him about fifty dollars for his travelling expenses for five months! A single incident shows the tender heart of the young explorer. Very few birds were visible except the ptarmigan. He says: "The little Alpine variety of the ptarmigan was now accompanied by its young. I caught one of these, upon which the hen ran so close to me that I could easily have taken her also. She kept continually jumping round and round me, but I thought it a pity to deprive the tender brood of their mother; neither would my compassion for the mother allow me long to detain her offspring, which I returned to her in safety." Tenderness to animals seems to be a striking characteristic of great men and women. During the journey, he found a modest little flower in the great northern forests, in the moss, and this he named _Linnæa borealis_, thinking it was so like himself, expanding in obscurity. He chose for his motto, _Tantus amor florum_, "So great is the love for flowers." On his return to Upsala, he began courses of private lectures in medicine, but so bitter was the envy of the before-mentioned professor that the archbishop was prevailed upon to prohibit private lectures. Thus deprived of a livelihood, Linnæus turned his attention to mineralogy, visiting the Swedish mines. The Governor of Dalecarlia was so pleased with him that he engaged him to investigate the productions of his country. Here he fell in love with the daughter of John Moræus, a well-to-do physician. Sara Elizabeth reciprocated the affections of the young man, who was told by the father that he must wait three years for a final answer; for, in truth, Linnæus's financial prospects were not bright. The University of Upsala did not want him, and there seemed to be no hope of writing or publishing his books on botany. But a man usually achieves little, who does not fight his way at every step. Now, indeed, for love's sake he must make his mark.
