Famous Men of Science Part 8

The influence of such a man can well be imagined. He became a guiding star to the young Gottingen student. If we could but estimate the value of right friendships in life! We flatter ourselves that we are too strong to be influenced, and yet we are greatly influenced for good or for evil by those with whom we a.s.sociate. Humboldt always chose intellectual friends, and the natural result followed.

In the spring of 1790, he left Gottingen, and, with Foster and Van Genns, took a journey to the Lower Rhine, Holland, Belgium, England, and France, studying docks, mines, botanic gardens, manufactures, and churches, and visiting literary celebrities. Still the new friends did not take the place of the old, for he writes to Wegener: "I beseech you, dearest Wegener, by all the affection which you know I bear you, never to forget our brotherly love and friendship. You are infinitely more to me than I can ever be to you. I have now seen the most celebrated places in Germany, Holland, and England--but, believe me, I have in seeing them never been so happy as while sitting in Steinbart's arm-chair."

The influence of this journey was never lost. Sixty-eight years afterward, Humboldt said: "For the s.p.a.ce of thirty years I have never known leisure but of an evening, and the half-century that I have spent in this ceaseless activity has been occupied in telling myself and others how much I owe my teacher and friend George Foster in the generalization of my views on nature, and in the strengthening and development of that which had already dawned in me, before those happy days of intimate friendship."

In the latter part of 1790, Humboldt went to Hamburg, to enter the School of Commerce. He wished to study political economy further, and to learn practical book-keeping. He wrote to a friend: "I am contented with my mode of life at Hamburg, but not happy, less happy even than at Gottingen, where the monotony of my existence was relieved by the society of one or two friends and the vicinity of some moss-grown mountains. I am, however, always contented when I feel that I am accomplishing the purpose I have in view.... My leisure hours are occupied with geology and botany.... In addition, I have begun to learn Danish and Swedish."

To Wegener he writes: "I have made considerable progress in general information, and I am beginning to be somewhat more satisfied with my attainments. I worked very hard at Gottingen, but all I have learned makes me feel only the more keenly how much remains still to know. My health suffered severely, but improved somewhat during my journey with Foster; yet even here I continue so closely occupied that I find it difficult to spare myself. There is an eager impulse within me, which often carries me, I fear, beyond the bounds of reason; and yet such impetuosity is always necessary to insure success."

The "eager impulse" was a sure indication of something to be accomplished by and by. Success does not come with half-hearted effort; it comes only through a force and persistence that will allow no barriers between us and the goal.

At Easter, 1791, Humboldt left Hamburg and hastened to the famous School of Mines at Freiberg, to study under the celebrated Werner. Here, as ever, he attached one ardent friend to himself, Freiesleben, a student in geology. Here every moment was occupied. He studied the works of the French chemists; Guyton de Moreau, Fourcroy, Lavoisier, and Berthollet.

He was daily in the mines, from six o'clock till twelve. He crowded six lectures into each afternoon. He made a study of the vegetation of that lower world, from which the sunlight is ever excluded, and the results were used later in his comprehensive work, "Flora Subterranea Fribergensis." He wrote articles for several scientific journals. A busy life, indeed, for the young man of twenty-two!

His friend Freiesleben says of Humboldt at this time:--

"The salient points of his attractive character lay in his imperturbable good-nature, his benevolence and charity, his remarkable and _unselfish amiability_, his susceptibility of friendship and appreciation of nature; simplicity, candor, and the absence of all pretension characterized his whole being; he possessed conversational powers that made him always lively and entertaining, together with a degree of wit and humor that led him sometimes to waggishness. It was these admirable qualities which in later years enabled him to soften and attach to himself the untutored savages, among whom he dwelt for months at a time, which obtained for him in the civilized world admiration and sympathy wherever he went, and which gained for him, while a mere student, the esteem and devotion of all cla.s.ses at Freiberg.

"He was kindly disposed towards every one, and knew how to make himself useful and entertaining in every circle of society; and it was only against every species of inhumanity and coa.r.s.eness, against every kind of insolence, injustice, or cruelty, that he ever manifested either scorn or indignation."

How the world loves "unselfish amiability;" a person who goes through life thinking for others, not irritable, not supersensitive, not censorious!

On Humboldt's return to Berlin in 1792, he was at once made "a.s.sessor in the Administrative Department of Mines and Smelting Works," a position for which he had previously applied. As a rule, places do not seek persons, however brilliant; they must seek places.

This was a fine opening for a young man, not yet twenty-three. He went to work with unbounded energy. He investigated the general form of mountains, collected information as to former methods of working the mines, by having three chests of mining doc.u.ments, belonging to the sixteenth century, brought to him for careful study, and made a report on the salt, alum, and vitriol works, and on the porcelain manufactory.

The government authorities were so pleased with his thorough report that he was appointed superintendent of mines in the two Franconian duchies.

He wrote to Freiesleben: "I am quite intoxicated with joy.... Do not feel anxious about my health; I shall take care not to over-exert myself, and after the first the work will not be heavy. I cannot conclude without acknowledging that it is again to you that I am indebted for this happiness; indeed I feel it only too keenly. What knowledge have I, dear Freiesleben, that has not been taught me by you!... How sweet is the thought to me that it is to you that I owe all this; it seems as if it bound me closer to you, as if I carried something about me that had been planted within me and cultivated by yourself...."

Thus all through life was the appreciative, warm-hearted man glad to show his grat.i.tude for the stimulus of intellectual friends.

Who does not love to be appreciated! How many of us wait to say kind things to our friends until death makes it impossible!

Again he wrote: "I possess a certain amount of vanity, and am willing to confess it; but I know the power of my own will, and I feel that whatever I set myself to do I shall do well."

While so earnestly engaged in study, Humboldt, with his benevolent heart, could not see the children of the miners grow up in ignorance.

He therefore opened free schools for them, and paid the teachers from his own purse. Not many young men at twenty-four would have thought of so admirable a plan.

Meantime he was experiencing the first keen joy of fame. The Elector of Saxony had sent the author of "Flora Fribergensis" a gold medal. The Swedish botanist Vahl had named a magnificent species of an East Indian laurel after him, the _laurifolia Humboldtia_. It had paid to be a student; to be led by the "eager impulse" within him.

The next year he wrote to Freiesleben:--

"You are aware that I am quite mad enough to be engaged upon three books at once.... I have discovered several new lichens. I have also been occupied upon the history of the weaving of the ancients.... My head is quite distracted with all I have to attend to--mining, banking, manufacturing, and organizing; ... the mines, however, are prospering.... I am promoted to be counsellor of mines at Berlin, with a salary, probably, of fifteen hundred thalers (here I have four hundred), and, after remaining there a few months, I shall most likely be appointed director of mines, either in Westphalia or Rothenburg, and receive from two thousand to three thousand thalers. I tell you everything, and open my heart to you."

In 1795, having resigned his position in the service of the state, because of his desire for travel and scientific work, with two friends, Freiesleben, and Lieutenant Reinhard von Haften, of Westphalia, he journeyed to Venice, going through the Tyrol and the Alps into Switzerland. They visited the mountains around Schaffhausen, Zurich, and Berne, and such notable men of science as De Luc, Pictet, and Saussure.

As Freiesleben said, "No subject having any reference to the physical const.i.tution of the earth, the atmosphere, or any point of natural history, was allowed to escape his attention."

An especial bond united Humboldt and the highly educated Von Haften, since between the latter's sister Minette and the young scientist there existed a devoted affection. This was cherished for ten years, but Humboldt's life of travel and exposure prevented a union which both ardently desired. He sacrificed his affections to science, and the loneliness of his later years proved the unwisdom of his choice.

On his return home, Humboldt set himself earnestly to the writing of two books: one on geology, the disposition of strata in mountain ma.s.ses; the other on the "Excitability of the Nerves and Muscles," describing over four thousand experiments. His devotion to science was shown by the painful experiments upon his own body, which brought permanent harm to his nervous system.

He wrote to a friend: "I applied two blisters to my back, each of the size of a crown-piece, and covering respectively the trapezius and deltoid muscles.... When the blisters were cut, and contact made with zinc and silver, I experienced a sharp pain, which was so severe that the trapezius muscle swelled considerably, and the quivering was communicated upwards to the base of the skull and the spinous processes of the vertebrae."

He also experimented with the noxious gases in mines, inventing lamps which were the forerunner of Sir Humphrey Davy's. Sometimes he was deprived of consciousness by the gases and saved only by the timely aid of friends.

Always longing for foreign travel, he went to Weimar, to make himself more fully ready for it, especially by the study of anatomy. Here lived his brother William, who had married a brilliant and intellectual woman, the intimate friend of the wife of Schiller.

Here Humboldt and Goethe became earnest friends. Goethe says: "During Humboldt's visit, my time has been usefully and agreeably spent; his presence has had the effect of arousing from its winter sleep my taste for natural science." Years afterward Goethe said to Eckermann: "Alexander von Humboldt has been with me for some hours this morning; what an extraordinary man he is! Though I have known him for so long, I am always struck with fresh amazement in his company. He may be said to be without a rival in extent of information and acquaintance with existing sciences. He possesses, too, a versatility of genius which I have never seen equalled. Whatever may be the subject broached, he seems quite at home in it, and showers upon us treasures in profusion from his stores of knowledge. He resembles a living fountain, whence flow many streams, yielding to all comers a quickening and refreshing draught. He will remain here a few days, and I already feel that I shall have lived through years in the time."

That Humboldt valued this friendship is shown by the dedication to Goethe of the first part of his "Travels in America."

The project of foreign travel was long delayed by sickness, war, and various disappointments. But, in life, obstacles are the common lot of mortals, and he alone is wise who b.r.e.a.s.t.s them cheerfully, patiently, and persistently. Humboldt said, "It is impossible not to feel the severity of this disappointment; but it is the part of a man to work, and not to yield to unavailing regrets."

"Hard! well, and what of that?

Didst fancy life one summer holiday, With lessons none to learn, and naught but play?

Go, get thee to thy task. Conquer or die!

It must be learned. Learn it then, patiently."

At last, in 1799, when Humboldt was thirty, the long contemplated journey to South America was about to be realized. He had already published some astronomical treatises on the determination of lat.i.tudes, trigonometrical measures of the Alpine ranges, etc.; had given lectures in Paris, before the National Inst.i.tute, on the nature of nitrous gas, and the possibility of a more exact a.n.a.lysis of the atmosphere; and had spent some time in Spain, with the well known botanist Bonpland, in collecting plants, and making observations in connection with meteorology, geology, and magnetism. While at Madrid, through Herr von Forell, a distinguished patron of science, Humboldt was received at court and obtained permission of the king to visit the Spanish colonies in America.

At his own expense, the best scientific instruments were procured, and June 5, 1799, at two o'clock in the afternoon, he and Bonpland, with their crew and a few others, sailed away, in the corvette Pizarro, for a five years' journey. He sent tender farewell messages back to "his family," as he called William's children, and then stifled any feelings of loneliness or homesickness which he had in his heart, by his favorite motto, "Man must ever strive after all that is good and great."

June 20, they were at the foot of the Peak of Teneriffe. He wrote to his brother: "I am quite in a state of ecstasy at finding myself at length on African soil, surrounded by cocoa-nut palms and bananas.... I returned last night from an excursion up the peak. What an amazing scene! What a gratification! We descended some way into the crater, perhaps farther than any previous scientific traveller.... What a remarkable spectacle was presented to us at this height of eleven thousand five hundred feet.... At two in the morning we were already on our way towards the last cone. The heavens were bright with stars, and the moon shone with a gentle radiance; but this calm was soon to be disturbed. The storm raged violently round the summit; we were obliged to cling fast to the edge of the crater. The wind rushed through the rifts with a noise like thunder, while a veil of cloud separated us from the world below."

After a voyage of nineteen days, the ship entered the harbor of c.u.mana, on the north coast of South America. Here they enjoyed the new and strange scenes; the houses built of satin-wood; the copper-colored Indians outside the town, living in bamboo huts, covered with the leaves of the cocoa-nut palm; these great trees from fifty to sixty feet high, with large red bunches of flowers. "Even the crabs," said Humboldt, "are sky-blue and gold!"

By November they had dried more than sixteen hundred plants, and described about six hundred new varieties. He had taken observations of the solar eclipse of October 28, and so severely burnt his face that he was obliged to remain in bed for two days.

Going to Caracas, they spent two months and a half climbing mountains, visiting hot springs, and forming an intimate acquaintance with tigers, crocodiles, monkeys, and boa constrictors. Here they discovered the singular cow-tree, with dry and tough leaves, but which gives out a sweet nourishing milk when an incision is made in its stem. "At sunrise this vegetable spring is the richest: then the negroes and the natives come from all sides, provided with large vessels to collect the milk, which turns yellow and thickens on the surface."

In February, 1800, the travellers traced the water system of the Orinoco, often in the midst of danger. Once, in a severe storm, their boat was two-thirds full of water. "Our position," says Humboldt, "was truly appalling; the sh.o.r.e was distant from us more than a mile, where a number of crocodiles could be discerned lying half out of the water.

Even if we had gained the sh.o.r.e against the fury of the waves and the voracity of the crocodiles, we should infallibly have either perished from hunger or been torn in pieces by the tigers, for the woods upon these sh.o.r.es are so dense and so intertwined with lianas as to be absolutely impenetrable. The strongest man, axe in hand, could hardly make his way in twenty days for the distance of a league. The river too is so little frequented that even an Indian canoe scarcely pa.s.ses oftener than once in two months. At this most momentous and perilous crisis a gust of wind filled the sails of our little vessel and effected in a marvellous manner our deliverance."

To his botanist friend, Willdenow, he writes:--"During four months of this journey we pa.s.sed the night in forests, surrounded by crocodiles, boa constrictors, and tigers, which are here bold enough to attack a canoe, while for food we had nothing better than rice, ants, bananas, and occasionally the flesh of monkeys, with only the waters of the Orinoco wherewith to quench our thirst. Thus have we with difficulty toiled, our hands and faces swollen with mosquito bites, from Mondvaca to the volcano of Duida, from the limits of Quito to the frontier of Surinam--through tracts of country extending over twenty thousand square miles, in which no Indian is to be met with, and where the traveller encounters only apes or serpents.

"In Guiana the mosquitoes abound in such clouds as to darken the air, and, as it is absolutely necessary to keep head and hands constantly covered, no writing can be done by daylight; the intolerable pain produced by the attacks of these insects renders it impossible to hold the pen steadily. All our work had therefore to be carried on by the light of a fire, in an Indian hut, where no ray of sunlight could penetrate, and into which we had to creep on our hands and knees. Here, if we escaped the torment of the mosquitoes, we were almost choked by the smoke. At Maypures, we and the Indians took refuge in the midst of the cascade, where the spray from the foaming stream kept off the insects. At Higuerote, the people are accustomed at night to lie buried three or four inches deep in sand, with only the head exposed."

Sometimes twenty-four Indians were in Humboldt's employ for months together, and fourteen mules were required to carry his instruments and plants.

After a year and a half spent in South America, Humboldt sailed for Cuba, where he remained for several months, collecting material for his "Political Essay on the Island of Cuba." From there he went to Quito, in Ecuador, crossing one of the most difficult pa.s.ses in the Andes, "the path so narrow that it rarely exceeds twelve or sixteen inches in width, and for the most part resembles an open gallery cut in the rock," and the Paramos of Pasto, "desert regions where, at a height of about twelve thousand feet above the sea, all vegetation ceases, and the cold is so intense as to penetrate to the very bones."

In June, 1802, they reached Quito, where, five years previously, an earthquake had destroyed forty thousand people. This month they made the ascent of Chimborazo, at that time regarded as the highest mountain in the world. "At certain places," he says, "where it was very steep, we were obliged to use both hands and feet, and the edges of the rock were so sharp that we were painfully cut, especially on our hands." As they climbed on, "one after another, we all began to feel indisposed, and experienced a feeling of nausea accompanied by giddiness, which was far more distressing than the difficulty of breathing.... Blood exuded from the lips and gums, and the eyes became bloodshot.... A few rock-lichens were to be observed above the line of perpetual snow, at a height of sixteen thousand nine hundred and twenty feet; the last green moss we noticed was growing about twenty-six hundred feet lower. A b.u.t.terfly was captured by M. Bonpland, at a height of fifteen thousand feet, and a fly was observed sixteen hundred feet higher.... When we were at a height of about seventeen thousand four hundred feet we encountered a violent hailstorm." The height of the mountain is over twenty-one thousand feet.

The intrepid Humboldt four times crossed the Andes; he travelled over Peru; he called attention to the fertilizing properties of guano, and then he sailed for Mexico, where he remained for a year. Here he met a lady greatly esteemed in that country, called the "fair Rodriguez," the most beautiful woman he had seen in his journeys, but whom he admired more "for her graces of mind than her beauty of person." He regarded her as an American Madame de Stael. It is a.s.serted that the grave man of science was deeply interested, but it was too late--she was already the wife of another, and had two children. Humboldt, like most other great men, all his life enjoyed the society of intellectual women, who were a constant inspiration.

After two months pa.s.sed at Havana, Humboldt came to the United States, spending three weeks with President Jefferson, at his home at Monticello. He never failed to speak in grateful terms of the courtesy he received from Americans. He studied carefully our inst.i.tutions, and greatly admired the republic; slavery alone saddened him.

On July 9, 1804, after five years of absence, he set sail for France.
