"Whenever I have found out that I have blundered, or that my work has been imperfect, and when I have been contemptuously criticised, and even when I have been overpraised, so that I have felt mortified, it has been my greatest comfort to say hundreds of times to myself, "that I have worked as hard and as well as I could, and no man can do more than this.""
The "Origin" has been translated into French, German, Italian, Dutch, Russian, Swedish, and many other languages. Huxley says of it, "Even a cursory glance at the history of the biological sciences during the last quarter of a century is sufficient to justify the a.s.sertion that the most potent instrument for the extension of the realm of natural knowledge which has come into men"s hands since the publication of Newton"s "Principia" is Darwin"s "Origin of Species.""
The year after the "Origin" was published, Darwin began arranging his notes for his two large volumes, "Variation of Animals and Plants under Domestication," which, however, were not published till 1868. On these two books he spent over four years. They are a wonderful collection of facts, gathered from books and from his own marvellous experiments and observations, confirming and ill.u.s.trating the law of "Natural Selection"
given in the "Origin."
Darwin had already received the Copley medal of the Royal Society, the greatest honor a scientific man can receive in England, and the Prussian Order "Pour le Merite," founded by Frederick II. The order consists of thirty German members and a few distinguished foreigners. In 1862 the "Fertilization of Orchids" was published, which, required ten months of labor. In this work Darwin took the utmost delight. He wrote to a friend who had sent him some of these flowers: "It is impossible to thank you enough. I was almost mad at the wealth of Orchids.... I never was more interested in any subject in my life than in this of Orchids." The peculiarities of the flowers therein described, as Darwin says, "transcend in an incomparable manner the contrivances and adaptations which the most fertile imagination of man could invent."
In the "Origin" he describes an orchid which "has part of its labellum or lower lip hollowed out into a great bucket, into which drops of almost pure water continually fall from two secreting horns which stand above it; and when the bucket is half full the water overflows by a spout on one side. The basal part of the labellum stands over the bucket, and is itself hollowed out into a sort of chamber with two lateral entrances; within this chamber there are curious fleshy ridges.
The most ingenious man, if he had not witnessed what takes place, could never have imagined what purpose all these parts serve. But Dr. Cruger saw crowds of large humble-bees visiting the gigantic flowers of this orchid, not in order to suck nectar, but to gnaw off the ridges within the chamber above the bucket; in doing this they frequently pushed each other into the bucket, and, their wings being thus wetted, they could not fly away, but were compelled to crawl out through the pa.s.sage formed by the spout or overflow.... The pa.s.sage is narrow, and is roofed over by the column, so that a bee, in forcing its way out, first rubs its back against the viscid stigma and then against the viscid glands of the pollen-ma.s.ses. The pollen-ma.s.ses are thus glued to the back of the bee which first happens to crawl out through the pa.s.sage of a lately expanded flower, and are thus carried away....
"When the bee, thus provided, flies to another flower, or to the same flower a second time, and is pushed by its comrades into the bucket and then crawls out by the pa.s.sage, the pollen-ma.s.s necessarily comes first into contact with the viscid stigma, and adheres to it, and the flower is fertilized. Now at last we see the full use of every part of the flower; of the water-secreting horns, of the bucket half full of water, which prevents the bees from flying away, and forces them to crawl out through the spout, and rub against the properly placed viscid pollen-ma.s.ses and the viscid stigma."
Darwin said: "The Botanists praise my Orchid-book to the skies.... There is a superb, but, I fear, exaggerated, review in the "London Review."
But I have not been a fool, as I thought I was, to publish; for Asa Gray, about the most competent judge in the world, thinks almost as highly of the book as does the "London Review.""
Darwin wrote several other books on plants. "The Movements and Habits of Climbing Plants" was published in 1875; "Insectivorous Plants," in 1875; "Effects of Cross and Self-Fertilization," in 1876; "The different Forms of Flowers on Plants of the Same Species," in 1877; "The Power of Movement in Plants," in 1880.
When writing his "Different Forms of Flowers," he said, "I am all on fire at the work;" and of "Insectivorous Plants," "I have been working like a madman at Drosera. Here is a fact for you which is certain as you stand where you are, though you won"t believe it, that a bit of hair, 1/78000 of one grain in weight, placed on gland, will cause _one_ of the gland-bearing hairs of Drosera to curve inwards, and will alter the condition of the content of every cell in the foot-stalk of the gland."
But he was growing tired with his constant and multifarious labors. He wrote to Hooker: "You ask about my book, and all that I can say is that I am ready to commit suicide; I thought it was decently written, but find so much wants rewriting that it will not be ready to go to printers for two months, and will then make a confoundedly big book. Murray will say that it is no use publishing in the middle of summer, so I do not know what will be the upshot; but I begin to think that every one who publishes a book is a fool."
In 1871 the "Descent of Man" was published. He worked on this book three years, and he wrote to his friend, Sir J. D. Hooker, that it has "half killed" him. For the first edition Darwin received over seven thousand dollars. It had an immense circulation in England and America, and created a furor in Germany.
Darwin believed "that man is descended from a hairy quadruped, furnished with a tail and pointed ears, probably arboreal in its habits, and an inhabitant of the Old World. This creature, if its whole structure had been examined by a naturalist, would have been cla.s.sed among the quadrumana, as surely as would the common and still more ancient progenitor of the Old and New World monkeys.
"The quadrumana and all the higher mammals are probably derived from an ancient marsupial animal, and this, through a long line of diversified forms, either from some reptile-like or some amphibian-like creature, and this again from some fishlike animal. In the dim obscurity of the past, we can see that the early progenitor of all the vertebrata must have been an aquatic animal, provided with branchiae, with the two s.e.xes united in the same individual, and with the most important organs of the body (such as the brain and heart) imperfectly developed. This animal seems to have been more like the larvae of our existing marine Ascidians than any known form."
Most naturalists believe, with Darwin, that man has developed from some lower form, but many urge that at some stage of development he received the gift of speech, and mental and moral powers, from an omnipotent Creator.
Darwin received much abuse and much ridicule for his views. Mr. James D.
Hague tells in "Harper"s Magazine" of a visit paid to the great scientist, when a picture in the "Hornet" was shown; the body of a gorilla, with the head of Darwin. The latter laughed and said, "The head is cleverly done, but the gorilla is bad; too much chest; it couldn"t be like that."
The "Descent of Man" shows the widest research, and is a storehouse of most interesting facts. "s.e.xual Selection" shows some of the most remarkable provisions of nature, and is as interesting as any novel.
This book, like the "Origin," has been translated into various languages.
In 1872 "The Expression of the Emotions in Man and Animals" was published. Over five thousand copies were sold on the day of publication. It was begun at the birth of his first child, thirty-three years before. He says, "I at once commenced to make notes on the first dawn of the various expressions which he exhibited, for I felt convinced, even at this early period, that the most complex and fine shades of expression must all have had a gradual and natural origin." He wrote to a college friend regarding this baby: "He is so charming that I cannot pretend to any modesty. I defy anybody to flatter us on our baby, for I defy any one to say anything in its praise of which we are not fully conscious.... I had not the smallest conception there was so much in a five-mouth baby. You will perceive by this that I have a fine degree of paternal fervor."
In 1881, "The Formation of Vegetable Mould, through the Action of Worms, with Observations on their Habits," was published. "Fragments of burnt marl, cinders, etc., which had been thickly strewed over the surface of several meadows were found, after a few years, lying at a depth of some inches beneath the turf, but still forming a layer." Ascertaining that this was the work of worms, Darwin made a study of their structure, habits, and work, in his garden, his fields, and in pots of earth kept in his study. The intelligence of worms, the construction of their burrows, and the amount of labor they can perform, are described in a most entertaining manner. Over fifty thousand worms are found in a single acre of land, or about three hundred and fifty-six pounds. "In many parts of England a weight of more than ten tons of dry earth annually pa.s.ses through their bodies, and is brought to the surface, on each acre of land.... Worms prepare the ground in an excellent manner for the growth of fibrous-rooted plants and for seedlings of all kinds.
They periodically expose the mould to the air, and sift it so that no stones larger than the particles which they can swallow are left in it.
They mingle the whole intimately together, like a gardener who prepares fine soil for his choicest plants.... The plough is one of the most ancient and most valuable of man"s inventions; but long before he existed the land was in fact regularly ploughed, and still continues to be thus ploughed, by earthworms. It may be doubted whether there are many other animals which have played so important a part in the history of the world as have these lowly organized creatures."
In three years eighty-five hundred copies of the "Earthworms" were sold.
Mr. Darwin was now seventy-two years old. Already many honors had come to him, after the severe and bitter censure. In 1877, he received the degree of LL.D. from Cambridge University. In 1878, he was elected a corresponding member of the French Inst.i.tute, and of the Berlin Academy of Sciences. In 1879, he received the Baly Medal of the Royal College of Physicians. In 1879, from the Royal Academy of Turin, the _Bressa_ Prize of twelve thousand francs. He valued highly two photographic alb.u.ms sent from Germany and Holland; one containing the pictures of one hundred and fifty-four noted scientific men; the other, of two hundred and seventeen lovers of natural science in the Netherlands. He wrote in thanks: "I am well aware that my books could never have been written, and would not have made any impression on the public mind, had not an immense amount of material been collected by a long series of admirable observers; and it is to them that honor is chiefly due. I suppose that every worker at science occasionally feels depressed, and doubts whether what he has published has been worth the labor which it has cost him, but for the few remaining years of my life, whenever I want cheering, I will look at the portraits of my distinguished co-workers in the field of science, and remember their generous sympathy."
He was made a member of more than seventy of the learned societies of the world; in America, Austria, India, Belgium, Denmark, France, Germany, Holland, Italy, Portugal, Russia, Spain, Sweden, Switzerland, and elsewhere.
Darwin"s work was now almost over. His dear friend Lyell had gone before him, of whom he said, "I never forget that almost everything which I have done in science I owe to the study of his great works." His brother Erasmus, to whom he was tenderly attached, died in 1881. In the spring of 1882 he was unable to work continuously as usual, and suffered from pain about the heart. On the night of April 18, he had a severe attack and fainted. When he was restored to consciousness, he said, "I am not the least afraid to die." He died the next day, April 19.
Darwin died as he had lived, with a heart overflowing with sympathy and tenderness. He said, "I feel no remorse from having committed any great sin, but have often and often regretted that I have not done more direct good to my fellow-creatures."
In his home life he was singularly blest. His son says, "No one except my mother knows the full amount of suffering he endured, or the full amount of his wonderful patience. For all the latter years of his life she never left him for a night; and her days were so planned that all his resting hours might be shared with her. She shielded him from every avoidable annoyance, and omitted nothing that might save him trouble, or prevent him becoming overtired, or that might alleviate the many discomforts of his ill-health. I hesitate to speak thus freely of a thing so sacred as the life-long devotion which prompted all this constant and tender care. But it is ... a princ.i.p.al feature of his life that for nearly forty years he never knew one day of the health of ordinary men, and that thus his life was one long struggle against the weariness and strain of sickness." And yet he accomplished all his wonderful work!
"In his relationship towards my mother, his tender and sympathetic nature was shown in its most beautiful aspect. In her presence he found his happiness, and through her his life--which might have been overshadowed by gloom--became one of content and quiet gladness."
He was the idol of his children, who used "to bribe him with sixpence to come and play in working hours." "We all knew the sacredness of working time," says Mr. Darwin"s daughter, "but that any one should resist sixpence seemed an impossibility.... Another mark of his unbounded patience was the way in which we were suffered to make raids into the study when we had an absolute need of sticking-plaster, string, pins, scissors, stamps, foot-rule, or hammer. These and other such necessaries were always to be found in the study, and it was the only place where this was a certainty. We used to feel it wrong to go in during work-time; still, when the necessity was great we did so. I remember his patient look when he said once, "Don"t you think you could not come in again; I have been interrupted very often?"... He cared for all our pursuits and interests, and lived our lives with us in a way that very few fathers do."
His son says: "The way he brought us up is shown by a little story about my brother Leonard, which my father was fond of telling. He came into the drawing-room, and found Leonard dancing about on the sofa, which was forbidden, for the sake of the springs, and said, "Oh, Lenny, Lenny, that"s against all rules!" and received for answer, "Then, I think you"d better go out of the room." I do not believe he ever spoke an angry word to any of his children in his life; but I am certain that it never entered our heads to disobey him.... How often, when a man, I have wished, when my father was behind my chair, that he would pa.s.s his hand over my hair, as he used to do when I was a boy. He allowed his grown-up children to laugh with and at him, and was, generally speaking, on terms of perfect equality with us."
He was very fond of flowers, and also of dogs. When he had been absent from home, on his return his white fox-terrier, Polly, "would get wild with excitement, panting, squeaking, rushing round the room, and jumping on and off the chairs; and he used to stoop down, pressing her face to his, letting her lick him, and speaking to her with a peculiarly tender, caressing voice."
He was very tender-hearted. A friend who often visited at Down told me that Mrs. Darwin one day urged her husband to punish the little dog for some wrong-doing. He took the animal tenderly in his arms and carried her out-of-doors, patting her gently on the head. "Why, Charles,"
remonstrated the wife, "she did not feel it." He replied, "I could do no more."
"The remembrance of screams or other sounds heard in Brazil," says Francis Darwin, "when he was powerless to interfere with what he believed to be the torture of a slave, haunted him for years, especially at night. In smaller matters, when he could interfere, he did so vigorously. He returned one day from his walk pale and faint from having seen a horse ill-used, and from the agitation of violently remonstrating with the man. On another occasion he saw a horse-breaker teaching his son to ride. The little boy was frightened, and the man was rough. My father stopped, and, jumping out of the carriage, reproved the man in no measured terms....
"A visitor, driving from Orpington to Down, told the man to go faster.
"Why," said the driver, "if I had whipped the horse _this_ much driving Mr. Darwin, he would have got out of the carriage and abused me well.""
His manner was bright and animated, and his face glowed in conversation.
He enjoyed fun, had a merry, ringing laugh, and a happy way of turning things. He said once, "Gray (Asa Gray of Harvard College) often takes me to task for making hasty generalizations; but the last time he was here talking that way, I said to him, "Now, Gray, I have one more generalization to make, which is not hasty; and that is, the Americans are the most delightful people I know.""
"He was particularly charming when "chaffing" any one," says his son, "and in high spirits over it. His manner at such times was light-hearted and boyish, and his refinement of nature came out most strongly. So, when he was talking to a lady who pleased and amused him, the combination of raillery and deference in his manner was delightful to see. When my father had several guests, he managed them well, getting a talk with each, or bringing two or three together round his chair....
"My father much enjoyed wandering slowly in the garden with my mother or some of his children, or making one of a party sitting out on a bench on the lawn; he generally sat, however, on the gra.s.s, and I remember him often lying under one of the big lime-trees, with his head on the green mound at its foot."
He had great perseverance in his work, and used often to say, "It"s dogged as does it;" and "Saving the minutes is the way to get work done." It was his habit to rise early in the morning, and after breakfast work from eight to half-past nine, and then read his letters.
At ten or half-past, he went back to his work till twelve. After exercise in the "Sandwalk," a narrow strip of land, one and a half acres in extent, with a gravel walk round it, planted with a variety of trees, in which he watched the birds and squirrels, he lunched and read his newspaper. After this he wrote letters, and about three o"clock rested for a time on the sofa, some of his family reading to him, often a novel,--the work of Walter Scott, George Eliot, Miss Austen, or others.
At four he walked again, worked from half-past four till half-past five, dined, and usually spent his evenings, after a game of backgammon with his wife, or hearing her play on the piano, in reading scientific books.
Conversation in the evening usually spoiled his rest for the night, but he could do a great amount of work if he kept to his regular routine. In each book, as he read it, he marked pa.s.sages bearing on his work. In reading a book or pamphlet, he made pencil lines at the side of the page, often adding short remarks, and at the end made a list of the pages marked.
Darwin said of himself: "At no time am I a quick thinker or writer; whatever I have done in science has solely been by long pondering, patience, and industry.... I think that I am superior to the common run of men in noticing things which easily escape attention, and in observing them carefully. My industry has been nearly as great as it could have been in the observation and collection of facts. What is far more important, my love of natural science has been steady and ardent.
"This pure love has, however, been much aided by the ambition to be esteemed by my fellow-naturalists. From my early youth I have had the strongest desire to understand or explain whatever I observed; that is, to group all facts under some general laws.... My habits are methodical, and this has been of not a little use for my particular line of work.
Lastly, I have had ample leisure from not having to earn my own bread.
Even ill-health, though it has annihilated several years of my life, has saved me from the distractions of society and amus.e.m.e.nt."
Mr. Darwin was never egotistical, or elated by his great success. He always felt and spoke modestly of his work. In the village people of Down he took a cordial interest, helping to found a Friendly Club, which he served as treasurer for thirty years. He also acted for some years as a county magistrate. The Vicar of Down, Rev. J. Brodie Innes, and Mr.
Darwin were firm friends for thirty years, yet, says Darwin, "we never thoroughly agreed on any subject but once, and then we stared hard at each other, and thought one of us must be very ill."
In the hall of the great Natural History Museum in London, a statue of Darwin was placed June 9, 1885, with appropriate addresses.
Darwin"s life is a most interesting study. That a boy who seemed in youth to have no special fondness for books, but an especial delight in collecting beetles; who appeared unfitted either for medicine or the church, should come to such a renowned manhood, is remarkable. His perseverance, his industry, his thought, his gentleness, his sunny nature in the midst of suffering, are delightful to contemplate. His books will be an enduring monument. He combined a great intellect and a great heart, which makes the most attractive nature, in either man or woman.
