Sounds are to me more reminiscent than sights; they bring back the sensations of childhood, and indeed all memories of my past life, in a way more touching and clear than what is seen. Wendell Holmes claims the sense of smell as most closely associated with memory; for me, as I say, it is that of hearing.
In this paper I shall wander in imagination through the different seasons in the home of my youth, and let the recalled rustic sounds lead where they will.
To children there is something impressive and almost sacred in the changes of the seasons, in the onset of winter, or the clear approach of spring. The first of these changes was heralded for me by the appearance of puddles frozen to a shining white; mysterious because the frost had drunk them dry in roofing them with ice, and especially delightful in the sharp crackling sound they gave when trodden on. This was the noise of the beginning of winter. Another winter memory is the humming whistle of the boys’ feet as they slid on the village pond, a remembrance that recalls my envious admiration of their heavily nailed boots, giving them an advantage in pace and a more noble style of sliding.
Another familiar sound was the wicked groaning crack that ran round the solitary pond on which we skated, as it unwillingly settled down to bear us on its surface. It had a threat in it, and reminded us how helpless we were, that the pond-spirit was our master and had our lives in its grip.
Another winter note was the hooting of invisible owls, boldly calling to each other from one moonlit tree to another. In the spring there was the querulous sound of the lambs, staggering half fledged in the cold fields among the half-eaten turnips beside their dirty yellow mothers. Not the sheep of the Dresden shepherdess, but rather of the old man in As You Like It, who warns Rosalind that shepherding has its ugly side. Yet it had something prophetic of more genial days.
Whistle: Fig. 1 As the sap began to rise in the trees my thoughts lightly turned to the making of whistles. I was taught the mystery by a labourer in my father’s employ and never departed from his method. The first thing was to cut a branch of some likely tree, a horse-chestnut for choice, severing it by an oblique cut, removing a ring of bark R and notching it at N. The bark had then to be removed in one piece so as to make the tube of the whistle. The first thing was to suck the bark and thoroughly wet it—a process I now believe to have been entirely useless. The bark was next hammered all over with the haft of the knife, which was held by the blade. Then when the inner layer of the bark was well bruised, it could be removed in one piece. To effect this I was taught to hold it in my handkerchief, and after a twist or two, a delicious yielding was experienced and the bark slipped off. The shiny white stick which remained in the other hand had to be cut in half, shaved in a particular way and again fitted into its bark tube. Then came the exciting moment,—would the thing whistle? The joy was short lived, and the whistles soon dried and shrank and ceased to satisfy the artist. But it was always possible to make a new one.
Since the above description was written, there has appeared in The Times Literary Supplement (February 22, 1917, p. 90) a notice of the poems of a Canadian writer [3] from which the reviewer quotes the following beautiful lines:
“So in the shadow by the nimble flood,
He made her whistles of the willow wood,
Flutes of one note with mellow slender tone;
(A robin piping in the dark alone).
Lively the pleasure was the wand to bruise,
And notch the light rod for its lyric use,
Until the stem gave up its slender sheath,
And showed the white and glistening wood beneath.
And when the ground was covered with light chips,
Grey leaves and green, and twigs and tender slips,” . . .
This could only have been written by one perfectly familiar with the art of whistle-making. But it seems to have been misunderstood by the reviewer, who says that he “once came upon one of these small Æolian harps in a wooded isle in the ‘Land of Afternoon,’” . . . and decided “that it was a work of superstition by Indian hands.” As an Æolian harp is a stringed instrument sounded by the wind, and a whistle belongs to the very distinct class of musical things sounded by human breath, I can only suppose that the reviewer has misunderstood the poem.
I cannot leave the Canadian poet without a reference to the beautiful line, (“A robin piping in the dark alone.”) A Canadian robin must surely make a song like ours, who seems also to sing in parenthesis.
The other form of rustic pipe that pleased me was a sort of oboe made from a dandelion stalk by squeezing it at one end. It had a rough nasal note, which could be controlled by holes cut in the stalk and stopped with the fingers. This again was but brief satisfaction, for the two halves of the reed soon curled outwards and ceased to speak. In later life this curling outwards was made use of in my work in the physiology of plants. I like to remember that my primeval oboe gave me the idea.
The village boys made ‘musics’ by fixing strips of laurel leaf into a split stick, and blowing violently into them, which set the leaf vibrating and made a coarse scream, but this instrument we despised, and I think rightly, for it had none of the pleasant tone of the whistle, nor was there any art in the making of it.
A primeval musical instrument called the ‘Whit horn’ I have seen in the possession of the late Mr. Taphouse, of Oxford. It is a conical tube of bark held together with thorns and sounded by means of a rough oboe-reed made of bark; there were no finger-holes, and is said to have yielded a harsh shriek on one note. It was, I think, played on May 1st, or else at Whitsuntide. It is to Mr. Taphouse that I owe my introduction to the pipe and tabor which form the subject of a paper in this volume. The pipe is shrill in its upper register, but this is no great fault in an instrument meant to be played out of doors: the same fault is to be found with the flageolet, and the penny whistle. But the last named instrument is reminiscent of a man playing outside a London public-house, and we know from the story of the perfidious Sergeant in The Wrong Box to what lengths it may lead us. [5]
The most truly rustic instrument (and here I mean an instrument of polite life—an orchestral instrument) is undoubtedly the oboe. The bassoon runs it hard, but has a touch of comedy and a stronger flavour of necromancy, while the oboe is quite good and simple in nature and is excessively in earnest; it seems to have in it the ghost of a sunburnt boy playing to himself under a tree, in a ragged shirt unbuttoned at the throat, a boy created by Velasquez. To hear an oboe actually played as a rustic instrument one must go to Brittany, where it accompanies the national bagpipe or ‘biniou.’ To a reed-instrument player it was painful to see the oboist bite a bit off his reed when the tone was not to his liking!
From this digression, originating in the whistle cut from a horse-chestnut bough, I return to some less artificial sounds. I must say a word about the song of birds, but my knowledge of the subject is but small. The most obvious of spring-time sounds is the voice of the cuckoo. I confess to liking the muttering chuckle which, in an unscientific mood, I have supposed to mean that an egg has successfully been laid in a hedge-sparrow’s nest. But the cuckoo’s “word in a minor third” is always delightful. The bird is neither more nor less of a foreigner than a willow-wren, yet he has, in comparison to the wren’s subdued chromatic warble, a song so self-assertive, and a tone so unlike our other birds, that one feels him an obvious exotic, a foreigner of so glorious and dashing a nature that one is grateful to him for singing among flat ploughed lands and monotonous hedges. I fancy the Welsh proverb, “Who would have thought the cuckoo would sing on the turf-heaps of the mountains,” is a poetic reflexion of this thought.
Of the nightingale I have nothing to say, except to put on record a true remark of Sir Charles Stanford’s, viz., that he sings in a syncopated rhythm. But, though I lived in a nightingale land, it is another bird that most clearly brings back to me the country of my boyhood, I mean the night-jar. He has something of antique mystery which I do not find in the nightingale, as he purrs on his only note through the warm night. There is something unknown and primæval and vaguely threatening in his relentless simplicity. Can it be that I inherit from a stone-age ancestor both the fear and love of the bull-roarer?
Another bird that moves one in a very different way is the robin, of whom it is hard to say whether he has more of tears or smiles in his recitative. In comparison to the night-jar he seems like a civilised human soul who has quite modern sorrows, and has half forgotten them in quiet contentment with the autumn sunshine. The blackbird has a tinge of the robin’s sentiment, but it is over-borne by the glory of his song as a whole, which is pure gold, like his beak.
The chaffinch is not an interesting person, and he is so numerous that one soon becomes weary of him and his song. Let us hope that he expresses his real nature in the building of his pretty nest rather than in song. This must, I think, often happen, and to take an example from human builders, it is not inconceivable that the architect of St. John’s College Chapel, Cambridge, may have sung delightfully. But there are limits to one’s faith, and personally I cannot imagine the desecrator of Pembroke College in the same injured town of Cambridge practising any art in a way that would please me.
To return to birds—the greenfinch is a pleasant singer, or perhaps a conversationalist. I am never tired of hearing him repeat the word “Squeese” as he sits hidden in the heavy shade of the summer elms. His twinkling bell-note with its contented simplicity is also attractive. His cousin, the bunting, makes remarks not unlike those of the greenfinch; and he appears to address them by preference to the travellers on dusty high roads, where he passes much of his time sitting on telegraph wires. The anchorite yellow-hammer persistently declining cheese with his bread is always pleasant. Professor Newton used to say that the spring begins with the yellow-hammer’s song. According to Blomefield’s Calendar [8] the average date in Cambridgeshire is February 16, but he has been known to sing on January 30—rather a wintry beginning for spring. I have never made up my mind as to what the kitty-wren says or sings. He is always in a desperate hurry to get through his piece, as if he were afraid of lagging behind the beat of some invisible conductor. In consequence of this there is a want of restraint, and a style that suggests a shy child gabbling a show bit of poetry. But I repent these words for I love the kitty-wren.
There are a multitude of other bird-sounds which are pleasant to hear as their turn comes round, for instance, the complaint of the wryneck, the “cuckoo’s mate,” who seems to me to be querulously expressing his dislike to my garden, which he tries year after year and deserts after a day or two.
I have never heard that contented bird the quail, who should be a wholesome lesson to all wrynecks. I should like to hear him as Schubert has him:
“Sitzend im Grünen
Mit Halmen umhüllt,”
and singing “Lobe Gott” all day in the rhythm with which the oboe praises God in the Pastoral Symphony.
Another bird, whom I take for a contented fellow, is the green woodpecker, for he goes through life laughing, but I am not quite sure that I should like his taste in jokes. He is always associated in my mind with a passage in a letter of my father’s: “At last I fell fast asleep on the grass, and awoke with a chorus of birds singing around me; and squirrels running up the trees, and some woodpeckers laughing, and it was as pleasant and rural a scene as ever I saw, and I did not care one penny how any of the beasts or birds had been formed.” [9]
There are many noises rather than notes which are most pleasant to hear. The invisible industrious corncrake, whose persistent cry comes from nowhere and everywhere at once. The harsh warning of the jay who seems to say “Man! man!” as he skulks off when his wood is invaded. The rough noise of the ox-eye sharpening his little saw, and many others.
Then I must not forget the noise of birds in flocks, ranging from the familiar wrangle of sparrows noisily going to roost, to the mysterious sound of great flights of birds migrating at night, one of the most romantic of sounds, but to me untranslatable, since I do not know the language of these wanderers.
I come now to human sounds. It was exciting to wake at 5 o’clock some morning in June, and to learn by the sound of scythes being whetted that the mowers had arrived, and that the hay harvest had actually begun. The field had been a great sea of tall grasses, pink with sorrel and white with dog-daisies, a sacred sea into which we might not enter. But now we could at least follow the mowers, and watch the growth of the tracks made by their shifting feet, and listen to the swish of the scythes as the swathes of fallen grass and flowers also grew in length. There was something military in their rhythm, and something relentless and machine-like in their persistence. But our admiration was mixed with pity from the time that one of them told us that after the first day’s mowing he was too tired to sleep. In later years another sound was associated with haymaking, when in an Alpine meadow the group of resting peasants were heard hammering the blades of their little pre-Raphaelite scythes to flatten the dents made by stones hidden among the grass.
A well-remembered sound that came near the end of the harvest was the cry of “Stand fast!” which was heard at intervals warning the man in the cart, whose duty it was to arrange the pitched-up hay, that a move was to be made. Why it was necessary to shout the warning so that it could be heard a quarter of a mile away I cannot say. But its impressive effect depended on its loud chant-like tone. This sound is connected with recollections of riding in the empty hay-cart, from the sea-green stack mysteriously growing in the corner of the field back to where hay waited to be carted. The inside of the hay-cart was enchantingly polished, and also full of hay-seed, which had a charm for me. The hay-making at Down was a leisurely affair, with many women gossiping as they gently turned the hay. There was, however, one man of whom we children were much afraid, a fierce red-eyed old labourer who acted as foreman, and did not hesitate to show that he thought us out of place in a hay-field.
One sound there was peculiar to Down,—I mean the sound of drawing water. In that dry chalky country we depended for drinking-water on a deep well from which it came up cold and pure in buckets. These were raised by a wire rope wound on a spindle turned by a heavy fly-wheel, and it was the monotonous song of the turning wheel that became so familiar to us. The well-house, gloomily placed among laurel bushes, had a sort of terrifying attraction for us, and I remember dropping pebbles and waiting—it seemed ages—for them to fall into the water below. We believed the well to be 365 feet deep, also that this was the height of the dome of St. Paul’s—I have never tested the truth of either statement. The opening was roofed in by a pair of hinged flaps, or doors, and I especially liked the moment when the rising bucket crashed into the doors from below, throwing them open with a brutal and roystering air, which one forgave it as having made a long and dangerous journey up from the distant water. But the best was when the empty bucket went down, and the fly-wheel spun round till its spokes were invisible. Then was the time to remember the death of a dog (called Dick) who was killed by jumping through the flying wheel. I envied my elder brothers who could actually remember Dick: to me he was only a tragic myth. I imagine that in hot dry weather more water was drawn, or else that being more constantly out of doors we heard more of it. It is at least certain that the sound of the well came to be associated with peaceful days and happy weather in that dear garden.
Another sound I like to recall is connected with the memory of my father. He daily took a certain number of turns round a little wood planted by himself, and christened the Sandwalk. As he paced round it he struck his heavy iron-shod walking-stick against the ground, and its rhythmical click became a familiar sound that spoke of his presence near us, and was associated with his constant sympathy in our pursuits. It is a sound that seems to me to have lasted all those years that stretch from misty childish days until his death. I am sure that all his children loved that sound.
February, 1912.
Francis Galton was born on February 16th, ninety-two years ago, and to-day we are met together to remember him—a word that seems to me more in tune with his nature than the more formal expression commemorate.
He disliked pomposity, but he seems to have loved little private ceremonials. For instance, when he opened the first notebook in preparation for his autobiographical Memories, he began page I with Falstaff’s words: “Lord, Lord, how subject we old men are to this vice of lying”—an inverted appeal to truth which no man ever stood less in need of. And again, at the foot of the very last page of his Memories is a drawing of Galtonia candicans, a little ceremony without words, a hieroglyphic glorification of the honour paid him in giving his name to this African plant.
Many persons, and even some reviewers, form their opinions of books by reading half-a-dozen passages at random. I have been more scientific in selecting the first and last pages, and from these I conclude that a simple and kindly commemoration is not out of harmony with the genius of this great and loveable man.
I should like to express my appreciation of the honour done me in asking me to give the first Galton lecture. In many ways I am a bad choice, since I have had no share in his science of eugenics, neither has my research-work been directly connected with evolution. I can only hope that in consideration of my delight in the fibre and flavour of Galton’s mind, with its youth, its charm of humour, and its ever-springing originality and acuteness,—I say that I hope these considerations may excuse me for having undertaken an office for which I am in so many ways unfitted.
One of his most obvious characteristics was his love of method. I do not mean methodicalness, but that he took delight in knowing how to do all manner of things in the very best way. He also liked to teach his methods to others. Those who never saw him, or even read his books, will exclaim, “What a bore he must have been.” One might as well call the lightning a bore for explaining that the thunder was coming, or complain of the match for boring the gunpowder as to the proper way of exploding. With Galton’s explanations there was a flash of clear words, a delightful smile or gesture, which seemed to say: “That’s all—don’t let me take up your time.” Nobody was ever more decidedly the very antithesis of a bore than Francis Galton.
He first appeared on the literary and scientific stage as a traveller, geographer, and author of a book on South Africa (1853), and it was the experience there gained that enabled him to write two years later, in 1855, that wonderful book, The Art of Travel. There he teaches such vitally important things as how to find water, how to train oxen as pack animals, to pitch a tent, to build a fire, to cook, and a thousand other secrets.
He liked, of course, to be useful to weary and thirsty travellers, but he was as much, or more, impelled by the love of method for its own sake. He was in fact an artist in method. The same thing is shown in a letter he wrote to Nature near the end of his life, explaining how to cut a cake on scientific principles so that it shall not become stale. This again was not so much a philanthropic desire that his fellow men should not have dry cake, as delight in method.
When I re-read The Art of Travel quite recently, I could not find his method of preventing a donkey braying. My recollection is that, observing a braying donkey with tail erect, he argued that if the tail were forcibly kept down, as by tying a stone to it, the braying would not occur. I certainly believe myself to have read or heard that this most Galtonian plan succeeded.
Later in life he tried to make his unique knowledge of value to his country. He writes: [15]
“The outbreak of the Crimean War showed the helplessness of our soldiers in the most elementary matters of camp-life. Believing that something could be done by myself towards removing this extraordinary and culpable ignorance, I offered to give lectures on the subject, gratuitously, at the then newly-founded camp at Aldershot.”
He received no answer from the War Office, but a personal application to Lord Palmerston led to his being installed. He speaks of a few officers attending his course, and adds that the “rude teachings of the Crimean War soon superseded” his own.
In relation to what I have been speaking of, I must here be allowed to turn back to an earlier period of his life. In illustrating the different dispositions of his sisters, both of whom were dear to him, Galton writes:
“My eldest sister was just, my youngest merciful. When my bread was buttered for me as a child, the former picked out the butter that filled the big holes, the latter did not. Consequently I respected the former, and loved the latter.”
Have we not here an early appreciation of method, or must we merely class the memory with the scene in “Great Expectations,” where the terrifying elder sister, Mrs. Joe, prepares bread and butter for her husband and for Pip (her little brother) in an eminently just and disagreeable manner. May I be allowed to add that a love of butter in the big holes is not hereditary in all branches of the family; I should have loved the sister who picked it out.
At a later stage in his boyhood Galton transferred his study of method from his sisters to his schoolmasters. He describes what he suffered from the absurd limitations (which still exist) in the education of English boys, and chafed at the teaching he received. “Grammar,” he says, “and the dry rudiments of Latin and Greek were abhorrent to me, for there seemed so little sense in them.” He suffered in fact like his cousin, Charles Darwin, who groaned over the classics at Shrewsbury School, and forgot what he learned, even to some of the Greek letters, by the time he was nineteen.
In 1838, when Galton was sixteen years of age, he became an indoor pupil at the Birmingham General Hospital. Here the education was at any rate practical enough, and to this coddled generation it sounds a rough introduction to medicine. He had to prepare tinctures, extracts, decoctions, and learned to make pills by hand—a slow enough process. In later life, when he saw a pill-making machine at work, it must have been his boyish memories which inspired the characteristic calculation that if a grandmotherly Government possessed forty-five of these engines, it could supply each inhabitant of the British Isles with one pill per diem.
It was in the surgery that he had most experience; he and the other indoor pupils were called up at all hours to dress burns, to patch broken heads, and reduce dislocations, with, as it seems, very little instruction. It was doubtless a fine bit of education in self-reliance, and he must have learned much that was of use in his South African travels. Whether as a student of method he approved of his rough and ready education is not quite clear. His genius for experiment, or rather that priceless capacity for extracting unexpected conclusions from experience, comes out in his account of a case in the Birmingham Hospital. An injured drayman was brought in dead drunk, and underwent amputation of the legs without any signs of feeling pain. This set Galton wondering whether patients might not with advantage be made drunk before operations—a query which was to be happily answered by the discovery of anæsthetics.
Another characteristic event was his attempt to learn the properties of all the drugs in the pharmacopœia by personal experience. He determined to dose himself alphabetically, but got no further than C., for the effects of croton oil put a stop to his thirst for first-hand knowledge.
We must pass over his time at King’s College, London, where, as he sat at lecture, he could see the “sails of the lighters moving in sunshine on the Thames,” a vision which stirred his blood with a longing for adventure, and which, as he characteristically noticed, always occurred when the weather-cock on the Horse Guards showed that the south-west wind was blowing.
We must, in like manner, skip his undergraduate days at Trinity, Cambridge. We thus arrive by a devious route at the period when he returned a traveller and geographer of recognized merit, and began the work with which he was practically connected for many years, as a member of the Meteorological Committee. His best-known contribution in the science was in a paper read before the Royal Society in 1862, where his discovery of the anticyclone was first described; but he also had a good deal to do with the printing and publishing of the now familiar weather charts. Meteorology takes us from 1861 to 1863, that is nearly to 1865, when his first paper on heredity appeared, which was at the same time his first paper on hereditary genius. This line of research was to form his chief claim to celebrity and must be separately treated.
Meanwhile I wish to say something of his love of experiment, which is a branch of his devotion to method. We know something of the more entertaining of his inquiries from his delightful book of Memories, yet I cannot but fear that he has left out many experiments even stranger than those he publishes. My father had a special affection for what in his own case he called “Fool’s experiments.” These are what, I am afraid, Galton may have omitted. Still there are records of some delightful lines of work. He is probably the only man who ever attempted to solve by experiment the problem of free will and determinism. He limited his inquiry to the question—whether there exists in human affairs such a thing as an “uncaused and creative action.” The experiment, or rather self-observation, was carried on (1879) for six weeks, almost continuously, and “off and on for many subsequent months.” He found that with practice he could nearly always trace the “straightforward causation” of a given action, which at first seemed to have been performed “through a creative act, or by inspiration.”
Then there was his attempt to experience the feelings of the insane. “The method tried was to invest everything I met, whether human, animal, or inanimate, with the imaginary attributes of a spy.” The trial was only too successful; by the time he had walked 1½ miles to the cab-stand at the east end of the Green Park “every horse in the stand seemed watching” him, “either with pricked ears, or disguising its espionage.” He adds that hours passed before this uncanny sensation wore off. On another occasion he managed to create in his mind the feelings of a savage for his idol, the idol in his own case being a picture of Mr. Punch.
These experiments seem to me very characteristic of the man in their originality, their humour, and their unexpected measure of success, for personally, I should have prophesied failure in all. They have a special bearing on Galton’s belief that a quasi-religious enthusiasm for eugenics may be built up. I have sometimes wondered that he should believe this great change so feasible, but I understand how he came to think so when I read of his strange power of impressing beliefs on himself, with such force as to leave a trail of discomfort in the mind after the make-believe had ceased.
These and similar trials were, I think, made in relation to his desire to weigh and measure human faculty in a broad sense. I remember his telling me of his experiments on the mind of the British cabman. His method was to use alternately two different forms of the address to which he wished to go. Thus on Monday he would tell the man to drive him home to 42, Rutland Gate, on Tuesday he would say, “Rutland Gate, 42,” and so on. My recollection is that the cabmen understood more quickly the familiar formula in which the number precedes the name of the street.
There was also a characteristic experiment or inquiry into the intensity of boredom in a lecture audience, by counting the number of fidgets per man per minute. In this case to avoid the open use of a watch, he estimated time by the number of his own breaths, “of which there are fifteen in a minute.” I hope my brother [21] will forgive my adding that he found the Royal Geographical Society meetings good hunting-ground for fidgets, for as Francis Galton remarks, “Even there, dull memoirs are occasionally read.”
Nor must I forget his plan of marking, by means of a hidden apparatus, the beauty of the women he met in the streets of different towns. He classified them as pretty, ugly, and indifferent; in this beauty competition London came out at the top; Aberdeen, I regret to say, was at the bottom.
But in considering the measurement of human faculty we have got quite out of any reasonably chronological sequence, for the book bearing that title appeared in 1883. But the estimation of human characteristics, especially in relation to heredity, was in Galton’s mind several years earlier, and in 1865 he wrote the two papers in Macmillan’s Magazine which contain the germs of his later work on heredity and eugenics. It is unfortunate that the research on heredity, together with its practical application to human welfare in the new science of eugenics, should not have more space given to it in his autobiographical Memories; there are but thirty-seven pages—or 11 per cent. of the whole book. The specific importance of the subjects here dealt with is so great that these thirty-seven pages outweigh all the rest of the book. We should like to have had a fuller account by the author of this remarkable work of 1865. He does, however, tell us—and it is a very striking statement—that the two articles “expressed then, as clearly as I can do now, the leading principles of Eugenics.”
The chief point in which he came to differ from the Macmillan articles was that he was then “too much disposed to think of marriage under some regulation, and not enough of the effects of self-interest and of social and religious sentiment.” I imagine that the pendulum has now swung the other way, and that one of the most hopeful and practical schemes is the prevention of marriage among habitual criminals and the feeble-minded.
Galton attributes his work in heredity in some measure to the publication of the Origin of Species, which, he says, “made a marked epoch” in his “mental development, as it did in that of human thought generally.”
That Galton personally felt no difficulty in assimilating the new doctrine, he characteristically ascribes to a “bent of mind that both its illustrious author” and himself had “inherited from” their “common grandfather, Dr. Erasmus Darwin.” But in our day the name of Galton is intimately connected in our minds with the science of heredity, and we forget that he, like lesser men, was a mine fired by the Origin. He was “encouraged,” he says, “by the new views to pursue many inquiries which had long interested” him “which clustered round the central topics of heredity.” This was the charge with which the mine had been loaded—the Origin was the fuse.
When that book was published in 1859, nearly everyone here to-night must have been too young to know anything of the great change in the colour of human thought which was ushered in. There are more who may remember how twelve years later, when the Descent of Man came out, there was still plenty of clerical and other forms of foolish bitterness. But a man needs to have been in the full swing of mental activity in 1859 to perceive the greatness of the change due to the Origin of Species.
His two papers in Macmillan’s Magazine, 1865 (Vol. XII., pp. 157 and 318), seem to me very remarkable, and, as I have said, they are passed over too lightly by the author in his Memories (p. 310). They contain a statistical proof of the inheritance of intellectual and moral qualities. [23] And those who would allow the truth of this statement must further agree that it is the first statistical demonstration of this important fact that the world has seen. And he insists that the whole spiritual nature of man is heritable, so that in his opinion there are no traces of that new element, “specially fashioned in Heaven,” which (he says) is commonly believed to be given to a baby at its birth.
The paper contains a very interesting discussion on the development of social virtues by natural selection. He gives, too, a characteristic explanation of that human attribute commonly known as Original Sin, the quality, in fact, which makes men yield to base desires against and in spite of their sense of what is right. He says [24] that here “the development of our nature under Darwin’s law of natural selection has not yet overtaken the development of our religious civilisation.” It may be more briefly described as the conflict between the individual desires with the tribal instincts. It must be remembered that for all this discussion Galton had no Descent of Man to guide him.
I shall come back later to his clear and courageous statement of eugenics in 1865. Meanwhile I must speak of heredity, a word, by the way, introduced by Galton, and for which he seems to have been taken to task.
With regard to the machinery of reproduction the essay is remarkable for containing what is practically identical with Weismann’s continuity of the germ-cell, and Galton’s priority is acknowledged by that author. But in science the credit goes to the man who convinces the world, not to the man to whom the idea first occurs. Not the man who finds a grain of new and precious quality, but to him who sows it, reaps it, grinds it and feeds the world on it. This is true of this very Macmillan’s Magazine article. Who would know of these admirable views on Hereditary Genius and Eugenics, if this were Galton’s only utterance? This is the grain which has increased and multiplied: and it is to-day familiar nutriment, and is now assiduously cultivated by the Eugenics Education Society. But if Natural Inheritance, and Hereditary Genius had not been written; if the papers on eugenics had not appeared, and especially if he had not convinced the world of his seriousness by creating a eugenic foundation at University College, where his friend Professor Karl Pearson carries on the Galtonian traditions—why then the paper in Macmillan would have counted for very little. But it was not quite unnoticed. By my father it is referred to in the Variation of Animals and Plants under Domestication. Galton was encouraged and reassured by Darwin’s appreciation of his work: his words in Hereditary Genius [25] are, “I feel assured that, inasmuch as what I then wrote was sufficient to earn the acceptance of Mr. Darwin . . . the increased amount of evidence submitted in the present volume is not likely to be gainsaid.” He was characteristically generous in owning his debt to the author of the Origin of Species, and characteristically modest in the value he ascribed to my father’s words.
The book on Hereditary Genius strikes me as most impressive. It seems as though the man whom the world had agreed to honour as an admirable and indeed a brilliant worker in geography and meteorology had suddenly grown big. He shows himself to have the power of sustaining a weighty argument in strong and temperate phrase, speaking as judge rather than advocate, and to have definitely taken rank with Darwin, Lyell, Hooker and Huxley, men whose pens have dinted the world, leaving their ineffaceable mark on the road trodden by the march of science.
When I was working at the Life and Letters of Charles Darwin, I naturally asked Mr. Galton for leave to publish the letters he had received from my father. But he would not agree. Mr. Darwin, he said, had spoken far too kindly of his work, and he preferred to keep the praise to himself. But later, when he wrote his Memories, [26a] he fortunately realised that it is wiser to think of the value to the world of such documents, than of private likes or dislikes. The letter my father wrote about Hereditary Genius which Galton says “made him most happy” begins:
“I have only read about 50 pages of your book . . . but I must exhale myself, else something will go wrong in my inside, I do not think I ever in all my life read anything more interesting and original.” [26b]
In reading this great book it is, I think, impossible to doubt the strength of the work. The quiet relentless way in which his territory is pegged out, and the clear wisdom with which the terms of the new science are defined, are equally impressive. And for lighter enjoyment his illustrations are to be recommended. He has to settle precisely what he means by a man being eminent or illustrious before he can begin to ask—are these qualities hereditary? An eminent man is one in four thousand, and to make clear what this implies, he writes: “On the most brilliant of starlight nights there are never so many as 4000 stars visible to the naked eye at the same time; yet we feel it to be an extraordinary distinction to a star to be accounted as the brightest in the sky.” [27a] If we could imagine that each new night shows us a fresh set of stars, we might speculate as to how many nights we should watch the sky before we found one bright enough for a Galton.
In the same way he tries to make us see a million, because in that number there is but one illustrious man. He worked it out in Bushey Park, where he had gone to see the horse-chestnuts in flower, and came to the astonishing conclusion that, taking one half only of the avenue and the flowers visible on the sunny side of that row, it would require 10 miles of avenue to give 1,000,000 spikes of blossom.
Later he defines mediocrity in a way not very flattering to those, who, like myself, live in the country. Mediocrity [27b] then “defines the intellectual power found in most provincial gatherings, because the attractions of a more stirring life in the metropolis and elsewhere are apt to draw away the abler classes of men, and the silly and imbecile do not take a part in the gatherings.” On this last point, by the way, I am not convinced. The research on the heredity of mental and moral characters leads naturally to eugenics, as in the ‘Macmillan’ paper of 1865. But before dealing with this I must say a few words about what, in the opinion of some, is Galton’s chief claim to eminence—the study of heredity as a whole. There is no doubt that he was the first to treat thoroughly and in a strict statistical method, the steps by which one generation passes into the next. He was pre-eminently a lover of statistics, he was indeed what Goschen called himself, “a passionate statistician.”
He used Gauss’s Law of Error, which Quetelet had already applied to human measurements. “The primary objects,” he says, “of the Gaussian Law of Error were exactly opposed, in one sense to those to which I applied them. They were to get rid of, or to provide, a just allowance for errors. But these errors or deviations were the very things I wanted to preserve and to know about.”
This conception of variation impressed him deeply, so that he remembered the exact spot in the grounds of Naworth Castle where it first occurred to him “that the laws of heredity [28] were solely concerned with deviations expressed in statistical units.”
What may be called the final result of Galton’s work in heredity is, I imagine, his ancestral law, namely that “the average contribution of each parent” to its offspring is one quarter, or in other words, that half of the qualities of the child can be accounted for when we know its father and mother. In the same way the four grandparents together contribute one quarter, and so on. He illustrates this by calculating how much Norman blood a man has who descends from a Baron of William the Conqueror’s. Assuming that the Baron weighed 14 stone, his descendant’s share in him is represented by 1/50 grain. [29]
This side of Galton’s work is, in the judgment of many, his greatest claim to distinction as a master in the science of heredity. How far this is so I shall not attempt to pronounce. It is possibly still too soon to do so. Nevertheless, it seems to me that Mendelism, the main facts of which are no longer in dispute, will compel the world (if it has not already done so) to look at variation in a very different way to that of Galton. The Mendelian does not, and never will, look at variation merely as a “deviation expressed in statistical units.” Nor can he accept the ancestral law, because he has convinced himself that some ancestors contribute nothing in regard to certain characters.
The contrast between Galtonism and Mendelism may be illustrated by an example, which, if not a strict analogy, has in it something illuminating, especially for those who do not know too much of the subject. Galton seems to me like a mediæval chemist, while Mendel is a modern one. Galton can observe, or can follow the changes that occur when two compounds are mixed. But he knows nothing of the mechanism of what occurs. But the Mendelian is like a modern chemist who calls the chemical elements to his aid, and is able to express the result of the experiment in terms of these elements. This is an enormous advantage, and if my analogy is to be trusted, it would seem as though a progressive study of heredity must necessarily be on Mendelian lines.
But it obviously does not follow that the laborious and skilful work of Galton and his school is wasted. Those who wish to have made plain to them how Biometrics may illuminate a problem which cannot as yet be solved in Mendelian fashion, should read Dr. Schuster’s most interesting book on eugenics. I am thinking especially of the question as to the heredity of tuberculosis and cancer. The relation between Galtonism and Mendelism is also well and temperately discussed in the late Mr. Lock’s Recent Progress in the Study of Variation, 1906.
But it is time to speak of Galton as a eugenist—on which if we look to the distant future his fame will rest. For no one can doubt that the science of eugenics must become a great and beneficent force in the evolution of man.
We must be persistent in urging its value, but we must also be patient. We should remember how young is the subject. As recently as 1901 Galton was, in his Huxley Lecture, compelled to speak of eugenics in these terms: [30]
“It has not hitherto been approached along the ways that recent knowledge has laid open, and it occupies in consequence a less dignified position in scientific estimation than it might. It is smiled at as most desirable in itself, and possibly worthy of academic discussion, but absolutely out of the question as a practical problem.” After explaining that the object of his discourse was to “show cause for a different opinion,” he goes on with what, in his restrained style, is strong language: “I shall show that our knowledge is already sufficient to justify the pursuit of this perhaps the grandest of all objects.” [31a]
At the close of the lecture he speaks out as to the difficulties and the pre-eminent value of eugenics, and once more of the oppressive “magnitude of the enquiry.”
No one who reads this lecture of Sir Francis Galton’s is likely to let eugenics go with a smile, and a remark that it is not a practical problem. It is one of the functions of the Eugenics Education Society to spread the sanely scientific views here set forth by Galton, and as far as I am able to judge, the Society has and is doing sound work in this direction.
In another essay, [31b] Galton discusses the meaning of the ‘eu’ in eugenics in a characteristic way. He imagines an attempt among the animals in the Zoological Gardens to establish a code of absolute morality. With customary love of detail he supposes the inquiry to be undertaken by some animal, such as a sparrow or a rat, which is intelligent and has easy access to all the cages, and is therefore able to collect opinions. There would be strongly pronounced differences between the carnivorous animals and those which form their natural prey. There would be a general agreement as to maternal affection, though fishes and the cuckoo would laugh at it. But all would agree on some eugenic principles: That it is better to be healthy and vigorous than sickly and weak—well-fitted for their part in life rather than the reverse—in fact, good specimens of their kind whatever that kind may be.
Sir Francis Galton goes on to give a list of qualities that “nearly every one except cranks would take into account in picking out the best specimens of his class.” The list includes “health, energy, ability, manliness and courteous disposition.” [32a] I wish he had thought of eugenic mothers, and had translated manliness into the feminine equivalents of courage and endurance. When I first read this list it struck me at once how highly distinguished was Galton himself in all these qualities. As we dwell on the qualities one by one, they seem to call up echoes from the image we have of his character. “Ability, manliness, and courteous disposition,” how strong these were in him! I cannot help feeling that he might have added one more quality from his own treasure-house, namely, a sense of humour, which is so priceless an antiseptic to sentimentality, and was markedly present in his character.
In this same lecture [32b] Galton sums up the stages in the development of eugenics. (1) “It must be made familiar as an academic question.” (2) As a practical subject worthy of serious consideration. (3) It must be “introduced into the national conscience, like a new religion.” He recapitulates in an eloquent phrase: “It has, indeed, strong claims to become an orthodox religious tenet of the future, for Eugenics cooperates with the workings of Nature, by securing that humanity shall be represented by the fittest races. What Nature does blindly, slowly, and ruthlessly, man may do providently, quickly, and kindly.”
Here we see the future of eugenics marked out for us, and the last sentence might well serve as a motto for this Society. How are we to work for the cause?
It is true that our opinions are formed by the daily papers, and our actions as a nation are determined by political parties which come and go largely by chance. But however our opinions originate, if they are strongly and persistently urged by a large majority of Englishmen, great changes in the manner of human life may be effected. Persistence is the great thing in all reforms: in the words of my father’s favourite quotation—“It’s dogged as does it.” Francis Galton has been temperately persistent in a marked degree. His caution and wisdom are illustrated by the dates of his writings on eugenics and heredity, which placed in order suggest a regiment relentlessly advancing, not a bunch of heroes rushing on a breach:—

His temperate advance is all the more striking when we remember the fiery impatience with which in Hereditary Genius he spoke of the harm done by the Church in ordaining that the intellectuals, the literary, and the sensitive should be celibates, and of the wholesale slaughter by the Holy Inquisition of the courageous and clear minded who dared to think for themselves.
From the first he had the support of Charles Darwin, who never wavered in his admiration of Galton’s purpose, though he had doubts about the practicality of reform. His hesitation in regard to eugenic method is expressed with a wise proviso as to future possibilities: “I have lately been led,” he says, “to reflect a little . . . on the artificial checks, but doubt greatly whether such would be advantageous to the world at large at present, however it may be in the distant future.” [34a] In the first edition of the Descent of Man (1874), [34b] he distinctly gives his adherence to the eugenic idea by his assertion that man might by selection do something for the moral and physical qualities of the race. It is a great thing that this Society should have had Francis Galton for its Honorary President. It entitles us to feel assured that in following the line of action marked out for ourselves we are on the right track, and that in the difficult pioneer work of helping the English public to realise the deadly need of eugenic reform we are following in Galton’s steps. We are also so fortunate as to have received encouragement and help at the hands of some of the leaders in the science of heredity, Weismann, Yves Delage, Ray Lankester, the late Adam Sedgwick, Poulton, Bateson, and others.
Galton says somewhere [35] that great men have long boyhoods. This was certainly true of him, though I should rather describe as youthful the delightful qualities that never faded out of his nature. It is, I believe, the correct thing to speak of the “golden dreams of youth,” and if by this hackneyed phrase we mean a keenly imaginative outlook, a hopefulness with a certain dash about it, a generous courage—tinged with romance—then Francis Galton had undying youth. And this makes his seriously measured progress in eugenics all the more worthy of our admiration.
In one of the Macmillan articles he wrote: “Many plan for that which they can never live to see. At the hour of death they are still planning.”
It was thus that Francis Galton died, and as year after year we meet together on February 16th, let us think of him and his plannings with affection and respect.
It is sometimes asserted that the power of movement is a character distinguishing animals from plants. This statement arises to some extent from an obvious confusion of thought. Trees are stationary, they are rooted to one spot, but they are not therefore motionless. We think them so because our eyes are dull—a fault curable with the help of a microscope. And when we get into the land of magnification, where the little looks big and the slow looks quick, we see such evidence of movement that we wonder not to hear as well as see the stream of life that flows before our eyes.
In speaking of the cells of which plants are built, Huxley said that a plant is “an animal enclosed in a wooden box.” It is this prisoner, the living protoplasm, that we may watch pacing round its prison walls. And we may see it stop as though frightened at our rough usage, and then, after a hesitating twitch or two, we see it recover and once more flow round the cell. Or we can watch under the microscope minute free-swimming plants rushing across the field of view, all one way, like a flock of little green sheep that we can drive to and fro with a ray of light for a sheep-dog.
But I am not going to deal with microscopic matters, but rather with things on a bigger scale which can be seen with the naked eye. I will begin by trying to show that very obvious movements are to be seen in every kitchen garden, or in every garret window, where a scarlet runner is grown for its red flowers’ sake.
In a scarlet runner the shoot is not completely vertical, but bends over to one side. To record the movements of the plant a series of photographs may be taken vertically from above the plant, so that the end of the shoot shows like the hand of a watch against a sort of clock-face on which the points of the compass are marked. Such photographs show how the shoot swings round in its instinctive search for another stick to climb.
This well-known movement is performed by a co-ordinated series of curvatures, the exact nature of which need not trouble us now. Let us rather consider the less obvious power of co-ordination which enables a plant to grow upwards in a straight line. Think of a forest of pine trees, hundreds of thousands of them, all growing vertically up towards the sky. Here is a clear case of movement, for the leading shoots were once but a few inches from the ground, and now they are crawling along vertical lines 100 feet up in the air. It may be said that this is mere increase in size, not movement in the ordinary sense. But it may be made plain that the trees could not grow in this way had they not a power of curvature, to which the term movement cannot be refused.
As it is not easy to experiment on pine trees we may use a pot of mustard seedlings, which represents in miniature a forest of vertical stems. Now suppose the flower-pot upset and left lying on its side for a few hours: the seedlings will be found to have all recovered the vertical position, and they have done so by a bend which is just as much a case of movement as the flexure of a man’s arm, though it is effected by a very different mechanism. Not everyone realises how rapid this movement is. Fig. 2 is from a diagram made in the ordinary course of class-work at Cambridge, and illustrates this point. A shoot of Valerian was placed horizontally at 2.17, and a black line painted like a silhouette on a vertical sheet of glass to record its position at 2.30; similar lines were painted at intervals, forming a record of fairly rapid movement. If greater delicacy of observation had been practised, it would have been easy to show that the plant begins to curve up within a few minutes of being placed horizontally.
It is a remarkable fact that the plant should be stimulated, or stirred up, to a definite curvature by merely placing it horizontally. The curvature tends to bring the plant into the upright position, and when the whole stem has reached the vertical, the stimulus ceases to exist. It is as though the plant were in a condition of content when vertical, and of discontent in any other position, and as though the discontent expressed itself in curvature.
But the plant does not gain the vertical by a single continuous curvature; at first it overdoes the thing (see Fig. 2), and the end of the shoot may pass beyond the vertical by 20°–30°. But this new position, inasmuch as it is not vertical, originates a new stimulus, and the new curvature which follows brings the shoot back towards the upright position. It may again overshoot the mark, but by repeated corrections it finally attains the normal upright posture.
It is this power of correcting the line of growth whenever it deviates from the upright that enables the pine tree to grow straight upwards. And this is what I meant when I said that its habit of growth depends on regulated curvature, to which no one can refuse the name of movement.

The pine and the seedling have, in fact, a wonderful kind of sensitiveness—a sensitiveness to the force of gravity. To those accustomed to think of Mimosa as the sensitive plant par excellence my words may sound strange. But the sensitiveness of Mimosa is crude by comparison with that of the seedling. A plant with a perception of the position of the centre of the earth and a power of growing along the line so perceived is a much greater miracle than a leaf that closes its leaflets when burnt or cut or shaken.
I shall show that certain parts of the plant have the special quality of the perception of gravitation, but we are at present ignorant of how the act of perception is effected. We know something of the machinery of hearing or vision in animals, but in plants we can only guess that when a cell is placed horizontally a resulting change of pressure on the protoplasm produces that loss of equilibrium which is translated into curvature. It is, however, probable that Němec and Haberlandt are right, and that the stimulus depends on the pressure of solid particles, e.g. starch-grains, on the protoplasm. [40]
The use of this gravitational sensitiveness is clear enough. It is to the pine tree what a plumbline is to the builder, for neither plant nor man can build high unless he builds straight. A man has a general perception of the verticalness of his body and of surrounding objects, but he does not trust to this sense in placing brick on brick to make a house. He uses a plumb-line which tells him through his eye the precise line along which he must pile his bricks. The tree has also to pile one over another the cells or chambers in which its protoplasmic body lives, and this too must be done along a vertical line; but the plant is guided by the sensitiveness to gravity of which I have spoken.
It must be clearly understood that gravity does not act directly on the growth of plants. It does not act as a magnet acts on iron, or to take a better example, it does not simply act as gravity acts on the plumb-line in which the string is kept in a vertical line by the weight. It might be supposed that in some occult way the stem was mechanically kept straight like the string, and this indeed was the view formerly held about such roots as grow straight down into the earth. But it is not so; the thing is not explicable mechanically. Gravitation is nothing more than a sign-post or signal to the plant—a signal which the plant interprets in the way best suited to its success in the struggle for life, just as what we see or hear gives us signals of changes in the exterior world by which we regulate our conduct.
It may be said that this is hard to prove, and indeed, like other biological theories, it can only be shown to be true by its explaining a number of facts. It is interesting to try to explain the facts without the assumption in question. If gravity does not act indirectly as a signal it must act directly; and we must find a reason why, in the case of the mustard seedling above referred to, the stem has grown up and the root down. There is absolutely nothing in their structure or manner of growth to help us to see why this difference of behaviour under identical conditions should exist. And if, instead of placing the mustard seedling in the dark we had grown it near the window, [41] we should have come across another remarkable phenomenon, namely, that the stem grows towards, the root away from, the light—and this is equally inexplicable on a mechanical basis.
