When Dr. Rothman thought his pupil ready for the university, he sent him up to Lund, and the head-master of the Latin School gave him the letter he must bring, to be admitted. “Boys at school,” he wrote in it, “may be likened to young trees in orchard nurseries, where it sometimes happens that here and there among the saplings there are some that make little growth, or even appear as wild seedlings, giving no promise; but when afterwards transplanted to the orchard, make a start, branch out freely, and at last yield satisfactory fruit.” By good luck, though, Carl ran across an old teacher from Wexiö, one of the few who had believed in him and was glad to see him. He took him to the Rector and introduced him with warm words of commendation, and also found him lodgings under the roof of Dr. Kilian Stobæus.
Dr. Stobæus was a physician of renown, but not good company. He was one-eyed, sickly, lame in one foot, and a gloomy hypochondriac to boot. Being unable to get around to his patients, he always had one or two students to do the running for him and to learn as best they might, in doing it. Carl found a young German installed there as the doctor’s right hand. He also found a library full of books on botany, a veritable heaven for him. But the gate was shut against him; the doctor had the key, and he saw nothing in the country lad but a needy student of no account. Perhaps the Rector had passed the head-master’s letter along. However, love laughs at locksmiths, and Carl Linnæus was hopelessly in love with his flowers. He got on the right side of the German by helping him over some hard stiles in the materia medica. In return, his fellow student brought him books out of the library when the doctor had gone to bed, and Carl sat up studying the big tomes till early cockcrow. Before the house stirred, the books were back on their shelves, the door locked, and no one was the wiser.
No one except the doctor’s old mother, whose room was across the yard. She did not sleep well, and all night she saw the window lighted in her neighbor’s room. She told the doctor that Carl Linnæus fell asleep with the candle burning every single night, and sometime he would upset it and they would all be burned in their beds. The doctor nodded grimly; he knew the young scamps. No doubt they both sat up playing cards till dawn; but he would teach them. And the very next morning, at two o’clock, up he stumped on his lame foot to Carl’s room, in which there was light, sure enough, and went in without knocking.
Carl was so deep in his work that he did not hear him at all, and the doctor stole up unperceived and looked over his shoulder. There lay his precious books, which he thought safely locked in the library, spread out before him, and his pupil was taking notes and copying drawings as if his life depended upon it. He gave a great start when Dr. Stobæus demanded what he was doing, but owned up frankly, while the doctor frowned and turned over his notes, leaf by leaf.
“Go to bed and sleep like other people,” he said gruffly, yet kindly, when he had heard it all, “and hereafter study in the daytime;” and he not only gave him a key to his library, but took him to his own table after that. Up till then Carl had merely been a lodger in the house.
When he was at last on the home stretch, as it seemed, an accident came near upsetting it all. He was stung by an adder on one of his botanizing excursions, so far from home and help that the bite came near proving fatal. However, Dr. Stobæus’ skill pulled him through, and in after years he got square by labelling the serpent furia infernalis—hell-fury—in his natural history. It was his way of fighting back. All through his life he never wasted an hour on controversy. He had no time, he said. But once when a rival made a particularly nasty attack upon him, he named a new plant after him, adding the descriptive adjective detestabilis—the detestable so-and-so. On the whole, he had the best of it; for the names he gave stuck.
It was during his vacation after the year at Lund that Linnæus made a catalogue of the plants in his father’s garden at Stenbrohult that shows us the country parson as no mean botanist himself; for in the list, which is preserved in the Academy of Sciences at Stockholm, are no less than two hundred and twenty-four kinds of plants. Among them are six American plants that had found their way to Sweden. The poison ivy is there, though what they wanted of that is hard to tell, and the four-o’clock, the pokeweed, the milkweed, the pearly everlasting, and the potato, which was then (1732) classed as a rare plant. Not until twenty years later did they begin to grow it for food in Sweden.
When Carl Linnæus went up to Upsala University, his parents had so far got over their disappointment at his deserting the ministry that they gave him a little money to make a start with; but they let him know that no more was coming—their pocket-book was empty. And within the twelvemonth, for all his scrimping and saving, he was on the point of starvation. He tells us himself that he depended on chance for a meal and wore his fellow students’ cast-off clothes. His boots were without soles, and in his cheerless attic room he patched them with birch bark and card board as well as he could. He was now twenty-three years old, and it seemed as if he would have to give up the study that gave him no bread; but still he clung to his beloved flowers. They often made him forget the pangs of hunger. And when the cloud was darkest the sun broke through. He was sitting in the Botanical Garden sketching a plant, when Dean Celsius, a great orientalist and theologian of his day, passed by. The evident poverty of the young man, together with his deep absorption in his work, arrested his attention; he sat down and talked with him. In five minutes Carl had found a friend and the Dean a helper. He had been commissioned to write a book on the plants of the Holy Land and had collected a botanical library for the purpose, but the work lagged. Here now was the one who could help set it going. That day Linnæus left his attic room and went to live in the Dean’s house. His days of starvation were over.
In the Dean’s employ his organizing genius developed the marvellous skill of the cataloguer that brought order out of the chaos of groping and guessing and blundering in which the science of botany had floundered up till then. Here and there in it all were flashes of the truth, which Linnæus laid hold of and pinned down with his own knowledge to system and order. Thus the Frenchman, Sebastian Vaillant, who had died a dozen years before, had suggested a classification of flowers by their seed-bearing organs, the stamens and pistils, instead of by their fruits, the number of their petals, or even by their color, as had been the vague practice of the past. Linnæus seized upon this as the truer way and wrote a brief treatise developing the idea, which so pleased Dr. Celsius that he got his young friend a license to lecture publicly in the Botanical Garden.
The students flocked to hear him. His message was one that put life and soul into the dry bones of a science that had only wearied them before. The professor of botany himself sat in the front row and hammered the floor with his cane in approval. But his very success was the lecturer’s undoing. Envy grew in place of the poverty he had conquered. The instructor, Nils Rosén, was abroad taking his doctor’s degree. He came home to find his lectures deserted for the irresponsible teachings of a mere undergraduate. He made grievous complaint, and Linnæus was silenced, to his great good luck. For so his friend the professor, though he was unable to break the red tape of the university, got him an appointment to go to Lapland on a botanical mission. His enemies were only too glad to see him go.
