Nor is it alone from the feminine side that these forecasts are made. Certainly for the most part love has been cultivated more by women than by men. Primacy in the genius of intellect belongs incontestably to men, but in the genius of love it has doubtless oftener been achieved by women. They have usually understood better than men that in this matter, as Goethe insisted, it is the lover and not the beloved who reaps the chief fruits of love. "It is better to love, even violently," wrote the forsaken Portuguese nun, in her immortal Letters, "than merely to be loved." He who loses his life here saves it, for it is only in so far as he becomes a crucified god that Love wins the sacrifice of human hearts. Of late years, by an inevitable reaction, women have sometimes forgotten this eternal verity. The women of the twentieth century in their anxiety for self-possession and their rightful eagerness to gain positions they feel they have been too long excluded from, have perhaps yet failed to realize that the women of the eighteenth century, who exerted a sway over life that the women of no age before or since have possessed, were, above all women, great and heroic lovers, and that those two fundamental facts cannot be cut asunder. But this failure, temporary as it is doubtless destined to be, will work for good if it is the point of departure for a revival among men of the art of love.

Men indeed have here fallen behind women. The old saying, so tediously often quoted, concerning love as a "thing apart" in the lives of men would scarcely have occurred to a medieval poet of Provence or Florence. It is not enough for women to proclaim a new avatar of love if men are not ready and eager to learn its art and to practise its discipline. In a profoundly suggestive fragment on love, left incomplete at his death by the distinguished sociologist Tarde, 89 he suggests that when masculine energy dies down in the fields of political ambition and commercial gain, as it already has in the field of warfare, the energy liberated by greater social organization and cohesion may find scope once more in love. For too long a period love, like war and politics and commerce, has been chiefly monopolized by the predatory type of man, in this field symbolized by the figure of Don Juan. In the future, Tarde suggests, the Don Juan type of lover may fall into disrepute, giving place to the Virgilian type, for whom love is not a thing apart but a form of life embodying its best and highest activities.

When we come upon utterances of this kind we are tempted to think that they represent merely the poetic dreams of individuals, standing too far ahead of their fellows to possess any significance for men and women in general. But it is probable that Ovid, and certain that Dante, set forth erotic conceptions that were unintelligible to most of their contemporaries, yet they have been immensely influential over the ideas and emotions of men in later ages. The poets and prophets of one generation are engaged in moulding ideals which will be realized in the lives of a subsequent generation; in expressing their own most intimate emotions, as it has been truly said, they become the leaders in a long file of men and women. Whatever may yet be uncertain and undefined, we may assuredly believe that the emotion of love is far too deeply rooted in the depth of man's organism and woman's organism ever to be torn out or ever to be thrust into a subordinate place. And we may also believe that there is no measurable limit to its power of putting forth ever new and miraculous flowers. It is recorded that once, in James Hinton's presence, the conversation turned on music, and it was suggested that, owing to the limited number of musical combinations and the unlimited number of musical compositions, a time would come when all music would only be a repetition of exhausted harmonies. Hinton remarked that then would come a man so inspired by a new spirit that his feeling would be, not that all music has been written, but that no music has yet been written. It was a memorable saying. In every field that is the perpetual proclamation of genius: Behold! I create all things new. And in this field of love we can conceive of no age in which to the inspired seer it will not be possible to feel: There has yet been no love!

One of the most interesting phenomena of the early part of the nineteenth century was the immense expansion of the people of the so-called "Anglo-Saxon" race. 90 This expansion coincided with that development of industrial and commercial activity which made the English people, who had previously impressed foreigners as somewhat lazy and drunken, into "a nation of shopkeepers." It also coincided with the end of the supremacy of France in Europe; France had succeeded to Spain as the leading power in Europe, and had on the whole maintained a supremacy which Napoleon brought to a climax, and, in doing so, crushed. The growing prosperity of England represented an entirely new wave of influence, mainly economic in character, but not less forceful than that of Spain and of France had been; and this prosperity was reflected in the growth of the nation. The greater part of the Victorian period was marked by this expansion of population, which reached its highest point in the early years of the second half of that period. While the population of England was thus increasing with ever greater rapidity at home, at the same time the English-speaking peoples overspread the whole of North America, and colonized the fertile fringe of Australia. It was, on a still larger scale, a phenomenon similar to that which had occurred three hundred years earlier, when Spain covered the world and founded an empire upon which, as Spaniards proudly boasted, the sun never set.

When now, a century later, we survey the situation, not only has industrial and commercial activity ceased to be a special attribute of the Anglo-Saxons—since the Germans have here shown themselves to possess qualities of the highest order, and other countries are rapidly rivalling them—but within the limits of the English-speaking world itself the English have found formidable rivals in the Americans. Underlying, however, even these great changes there is a still more fundamental fact to be considered, a fact which affects all branches of the race; and that is, that the Anglo-Saxons have passed their great epoch of expansion and that their birth-rate is rapidly falling to a normal level, that is to say, to the average level of the world in general. Disregarding the extremely important point of the death-rate in its bearing on the birth-rate, England is seen to possess a medium birth-rate among European countries, not among the countries with a high birth-rate, like Russia, Roumania, or Bulgaria, nor among those with a low birth-rate, like Sweden, Belgium, and France. It was in this last country that the movement of decline in the European birth-rate began, and though the rate of decline has in France now become very gradual the long period through which it has extended has placed France in the lowest place, so far as Europe is concerned. In 1908 out of a total of over 11,000,000 French families, in nearly 2,000,000 there were no children, and in nearly 3,000,000 there was only one child. 91 The general decline in the European birth-rate, during the years 1901-1905, was only slight in Switzerland, Ireland and Spain, while it was large not only in France, but in Italy, Servia, England and Wales, and especially in Hungary (while, outside Europe, it was largest of all in South Australia). Since 1905 there has been a further general decline throughout Europe, only excepting Ireland, Bulgaria, and Roumania. In Prussia in 1881-1885 the birth-rate was 37.4; in 1909 it was only 31.8; while in the German Empire as a whole it is throughout lower than in Prussia, though somewhat higher than in England. In Austria and Spain alone of European countries during the twenty years between 1881 and 1901 was there any tendency for the fertility of wives to increase. In all other countries there was a decrease, greatest in Belgium, next greatest in France, then in England. 92

If we consider the question, not on the basis of the crude birth-rate, but of the "corrected" birth-rate, with more exact reference to the child-producing elements in the population, as is done by Newsholme and Stevenson, 93 we find that the greatest decline has taken place in New South Wales, then in Victoria, Belgium, and Saxony, followed by New Zealand. But France, the German Empire generally, England, and Denmark all show a considerable fall; while Sweden and Norway show a fall, which, especially in Norway, is slight. Norway illustrates the difference between the "crude" and the "corrected" birth-rate; the crude birth-rate is lower than that of Saxony, but the corrected birth-rate is higher. Ireland, again, has a very low crude birth-rate, but the population of child-bearing age has a high birth-rate, considerably higher than that of England.

Thus while forty years ago it was usual for both the English and the Germans to contemplate, perhaps with some complacency, the spectacle of the falling birth-rate in France as compared with the high birth-rate in England and Germany, we are now seen to be all marching along the same road. In 1876 the English birth-rate reached its maximum of 36.3 per thousand; while in France the birth-rate now appears almost to have reached its lowest level. Germany, like England, now also has a falling birth-rate, though it will take some time to sink to the English level. The birth-rate for Germany generally is still much higher than for England generally, but urbanization in Germany seems to have a greater influence than in England in lowering the birth-rate, and for many years past the birth-rate of Berlin has been lower than that of London. The birth-rate in Germany has long been steadily falling, and the increase in the population of Germany is due to a concomitant steady fall in the death-rate, a fall to which there are inevitable natural limits. 94 Moreover, as Flux has shown, 95 urbanization is going on at a greater speed in Germany than in England, and practically the entire natural increase of the German population for a quarter of a century has drifted into the towns. But the death-rate of the young in German towns is far higher than in English towns, and the first five years of life in Germany produce as much mortality as the first twenty-five years in England. 96 So that a thousand children born in England add far more to the population than a thousand children born in Germany. The average number of children per family in German towns is less than in English towns of the same size. These results, reached by Flux, suggest that in a few years' time the rate of increase in the German population will be lower than it is at present in England. In England, since 1876, the decline has been so rapid as to be equal to 20 per cent within a generation, and in some of the large towns to 40 per cent. Against this there has, indeed, to be set the general tendency during recent years for the death-rate to fall also. But this saving of life has until lately been effected mainly at the higher ages; there has been but little saving of the lives of infants, upon whom the death-rate falls most heavily. Accompanying this falling off in the number of children produced there has often been, as we might expect, a fall in the marriage-rate; but this has been less regular, and of late the marriage-rate has sometimes been high when the birth-rate was low. 97 There has, however, been a steady postponement of the average age at which marriage takes place. On the whole, the main fact that emerges is, that nowadays in England we marry less and have fewer children.

This is now a familiar fact, and perhaps it should not excite very great surprise. England is an old and fairly stable country, and it may be said that it would be unreasonable to expect its population to retain indefinitely a high degree of fertility. Whether this is so or not, there is the further consideration to be borne in mind that, during nearly the whole of the Victorian period, emigration of the most vigorous stocks took place to a very marked extent. It is not difficult to see the influence of such emigration in connection with the greatly diminished population of Ireland, as compared with Scotland; and we may reasonably infer that it has had its part in the decreased fertility of the United Kingdom generally.

But we encounter the remarkable fact that this decreased fertility of the Anglo-Saxon populations is not confined to the United Kingdom. It is even more pronounced in those very lands to which so many thousand shiploads of our best people have been taken. In the United States the question has attracted much attention, and there is little disagreement among careful observers as to the main facts of the situation. The question is, indeed, somewhat difficult for two reasons: the registration of births is not generally compulsory in the United States, and, even when general facts are ascertained, it is still necessary to distinguish between the different classes of the population. Our conclusions must therefore be based, not on the course of a general birth-rate, but on the most reliable calculations, based on the census returns and on the average size of the family at different periods, and among different classes of the population. A bulletin of the Census Bureau of the United States since 1860 was prepared a few years ago by Walter F. Wilcox, of Cornell University. It determines from the data in the census office the proportion of children to the number of women of child-bearing age in the country at different periods, and shows that there has been, on the whole, a fall from the beginning to the end of the last century. Children under ten years of age constituted one-third of the population at the beginning of the century, and at the end less than one-fourth of the total population. Between 1850 and 1860 the proportion of children to women between fifteen and forty-nine years of age increased, but since 1860 it has constantly decreased. In 1860 the number of children under five years of age to one thousand women between fifteen and forty-nine years of age was 634; in 1900 it was only 474. The proportion of children to potential mothers in 1900 was only three-fourths as large as in 1860. In the north and west of the United States the decline has been regular, while in the south the change has been less regular and the decline less marked. A comparison is made between the proportion of children in the foreign-born population and in the American. The former was 710 to the latter's 462. In the coloured population the proportion of children is greater than in the corresponding white population.

There can be no doubt whatever that, from the eighteenth century to the twentieth, there has been a steady decrease in the size of the American family. Franklin, in the eighteenth century, estimated that the average number of children to a married couple was eight; genealogical records show that, while in the seventeenth century it was nearly seven, it was over six at the end of the eighteenth century. Since then, as Engelmann and others have shown, there has been a steady decrease in the size of the family; in the earlier years of the nineteenth century there were between four and five children to each marriage, while by the end of the century the number of children had fallen to between four and but little over one. Engelmann finds that there is but a very trifling difference in this respect between the upper and the lower social classes; the average for the labouring classes at St. Louis he finds to be about two, and for the higher classes a little less. It is among the foreign-born population, and among those of foreign parents, that the larger families are found; thus Kuczynski, by analysing the census, finds that in Massachusetts the average number of children to each married woman among the American-born of all social classes is 2.7, while among the foreign-born of all social classes it is 4.5. Moreover, sterility is much more frequent among American women than among foreign women in America. Among various groups in Boston, St. Louis, and elsewhere it varies between 20 and 23 per cent, and in some smaller groups is even considerably higher, while among the foreign-born it is only 13 per cent. The net result is that the general natality of the United States at the present day is about equal to that of France, but that, when we analyse the facts, the fertility of the old native-born American population of mainly Anglo-Saxon origin is found to be lower than that of France. This element, therefore, is rapidly dwindling away in the United States. The general level of the birth-rate is maintained by the foreign immigrants, who in many States (as in New York, Massachusetts, Michigan, and Minnesota) constitute the majority of the population, and altogether number considerably over ten millions. Among these immigrants the Anglo-Saxon element is now very small. Indeed, the whole North European contingent among the American immigrants, which was formerly nearly 90 per cent of the whole, has since 1890 steadily sunk, and the majority of the immigrants now belong to the Central, Southern, and Eastern European stocks. The racial, and, it is probable, the psychological characteristics of the people of the United States are thus beginning to undergo, not merely modification, but, it may almost be said, a revolution. If, as we may well believe, the influence of the original North-European racial elements—Anglo-Saxon, Dutch, and French—still continues to persist in the United States, it can only be the influence of a small aristocracy, maintained by intellect and character.

When we turn to Canada, a land that is imposing, less by the actual size of the population than by the vast tracts it possesses for its development, the question has not yet been fully investigated; but such facts and official publications as I have been able to obtain all indicate that, in this matter, the English Canadians approximate to the native Americans. In the United States it is the European immigrants who maintain the general population at a productive level, and thus indirectly oust the Anglo-Saxon element. In Canada the chief dividing line is between the Anglo-Saxon element and the old French element in the population; and here it is the French Canadians who are gaining ground on the English elements in the population. Engelmann ascertained that an examination of one thousand families in the records of Quebec Life Assurance companies shows 9.2 children on the average to the French Canadian child-bearing woman. It is found also from the records of the French Canadian Society for Artisans that 500 families from town districts, taken at random, show 9.06 children per family, and 500 families from country districts show 9.33 children per family. 98 It must be remembered that this average, which is even higher than that found in Russia, the most prolific of European countries, is not quite the same as the number of children per marriage; but it indicates very great fertility, while it may be noted also that sterile marriages are comparatively rare among French Canadians, although among English Canadians the proportion of childless families is found to be almost exactly the same (nearly 20 per cent) as among the infertile Americans of Massachusetts. The annual Reports of the Registrar-General of Ontario, a province which is predominantly of Anglo-Saxon origin, show that the average birth-rate during the decade 1899-1908 has been 22.3 per 1000; it must be noted, however, that there has been a gradual rise from a rate of 19.4 in 1899 to one of 25.6 in 1908. The report of Mr. Prévost, the recorder of vital statistics for the predominantly French province of Quebec, shows much higher rates. The general birth-rate for the province for the year 1901 is high, being 35.2, much higher than that of England, and nearly as high as that of Germany. If, however, we consider the thirty-five counties of the province in which the population is almost exclusively French Canadian, we find that 35 represents almost the lowest average; as many as twenty-two of these counties show a rate of over forty, and one (Yamaska) reached 51.52. It is very evident that, in order to pull down these high birth-rates to the general level of 35.2, we have to assume a much lower birth-rate among the counties in which the English element is considerable. It must be remembered, however, that infant mortality is high among the French Canadians. The French Canadian Catholic, it has been said, would shrink in horror from such an unnatural crime as limiting his family before birth, but he sees nothing repugnant to God or man in allowing the surplus excess of children to die after birth. In this he is at one with the Chinese. Dr. E.P. La Chapelle, the President of the Provincial Conseil d'Hygiène, wrote some years ago to Professor Davidson, in answer to inquiries: "I do not believe it would be correct to ascribe the phenomenon to any single cause, and I am convinced it is the result of several factors. For one, the first cause of the heavy infant mortality among the French Canadians is their very heavy natality, each family being composed of an average of twelve children, and instances of families of fifteen, eighteen, and even twenty-four children being not uncommon. The super-abundance of children renders, I think, parents less careful about them." 99

The net result is a slight increase on the part of the French Canadians, as compared with the English element in the province, as becomes clear when we compare the proportion of the population of English, Scotch, Irish, and all other nationalities with the total population of the province, now and thirty years ago. In 1871 it was 21 per cent; in 1901 it was only 19 per cent. The decrease of the Anglo-Saxons may here appear to be small, though it must be remembered that thirty years is but a short period in the history of a nation; but it is significant when we bear in mind that the English element has here been constantly reinforced by immigrants (who, as the experience of the United States shows, are by no means an infertile class), and that such reinforcement cannot be expected to continue in the future.

From Australia comes the same story of the decline of Anglo-Saxon fertility. In nearly all the Australian colonies the highest birth-rate was reached some twenty or thirty years ago. Since then there has been a more or less steady fall, accompanied by a marked decrease in the number of marriages, and a tendency to postpone the age of marriage. One colony, Western Australia, has a birth-rate which sometimes fluctuates above that of England; but it is the youngest of the colonies, and, at present, that with the smallest population, largely composed of recent immigrants. We may be quite sure that its comparatively high birth-rate is merely a temporary phenomenon. A very notable fact about the Australian birth-rate is the extreme rapidity with which the fall has taken place; thus Queensland, in 1890, had a birth-rate of 37, but by 1899 the rate had steadily fallen to 27, and the Victorian rate during the same period fell from 33 to 26 per thousand. In New South Wales, the state of things has been carefully studied by Mr. Coghlan, formerly Government statistician of New South Wales, who comes to the conclusion that the proportion of fertile marriages is declining, and that (as in the United States) it is the recent European immigrants only who show a comparatively high birth-rate. Until 1880, Coghlan states, the Australasian birth-rate was about 38 per thousand, and the average number of children to the family about 5.4. In 1901 the birth-rate had already fallen to 27.6 and the size of the family to 3.6 children. 100 It should be added that in all the Australasian colonies the birth-rate reached its lowest point some years ago, and may now be regarded as in a state of normal equipoise with a slight tendency to rise. The case of New Zealand is specially interesting. New Zealand once had the highest birth-rate of all the Australasian colonies; it is without doubt the most advanced of all in social and legislative matters; a variety of social reforms, which other countries are struggling for, are, in New Zealand, firmly established. Its prosperity is shown by the fact that it has the lowest death-rate of any country in the world, only 10.2 per thousand, as against 24 in Austria and 22 in France; it cannot even be said that the marriage-rate is very low, for it is scarcely lower than that of Austria, where the birth-rate is high. Yet the birth-rate in New Zealand fell as the social prosperity of the country rose, reaching its lowest point in 1899.

We thus find that from the three great Anglo-Saxon centres of the world—north, west, and south—the same story comes. We need not consider the case of South Africa, for it is well recognized that there the English constitute a comparatively infertile fringe, mostly confined to the towns, while the earlier Dutch element is far more prolific and firmly rooted in the soil. The position of the Dutch there is much the same as that of the French in Canada.

Thus we find that among highly civilized races generally, and not least among the English-speaking peoples who were once regarded as peculiarly prolific, a great diminution of reproductive activity has taken place during the past forty years, and is in some countries still taking place. But before we proceed to consider its significance it may be well to look a little more closely at our facts.

We have seen that the "crude" birth-rate is not an altogether reliable index of the reproductive energy of a nation. Various circumstances may cause an excess or a defect of persons of reproductive age in a community, and unless we allow for these variations, we cannot estimate whether that community is exercising its reproductive powers in a fairly normal manner. But there is another and still more important consideration always to be borne in mind before we can attach any far-reaching significance even to the corrected birth-rate. We have, that is, to bear in mind that a high or a low birth-rate has no meaning, so far as the growth of a nation is concerned, unless it is considered in relation to the death-rate. The natural increase of a nation is not the result of its birth-rate, but of its birth-rate minus its death-rate. A low birth-rate with a low death-rate (as in Australasia) produces a far greater natural increase than a low birth-rate with a rather high death-rate (as in France), and may even produce as great an increase as a very high birth-rate with a very high death-rate (as in Russia). Many worthy people might have been spared the utterance of foolish and mischievous jeremiads, if, instead of being content with a hasty glance at the crude birth-rate, they had paused to consider this fairly obvious fact.

There is an intimate connection between a high birth-rate and a high death-rate, between a low birth-rate and a low death-rate. It may not, indeed, be an absolutely necessary connection, and is not the outcome of any mysterious "law." But it usually exists, and the reasons are fairly obvious. We have already encountered the statement from an official Canadian source that the large infantile mortality of French Canadian families is due to parental carelessness, consequent, no doubt, not only on the dimly felt consciousness that children are cheap, but much more on inability to cope with the manifold cares involved by a large family. Among the English working class every doctor knows the thinly veiled indifference or even repulsion with which women view the seemingly endless stream of babies they give birth to. Among the Berlin working class, also, Hamburger's important investigation has indicated how serious a cause of infantile mortality this may be. By taking 374 working-class women, who had been married twenty years and conceived 3183 times, he found that the net result in surviving children was relatively more than twice as great among the women who had only had one child when compared to the women who had had fifteen children. The women with only one child brought 76.47 per cent of these children to maturity; the women who had produced fifteen children could only bring 30.66 of them to maturity; the intermediate groups showed a gradual fall to this low level, the only exception being that the mothers of three children were somewhat more successful than the mothers of two children. Among well-to-do mothers Hamburger found no such marked contrast between the net product of large families as compared to small families. 101

The infantile mortality has increased in Germany, as usually happens, with the increased employment of women, and, largely from this cause, has nearly doubled in Berlin in the course of four years, states Lily Braun (Mutterschutz, 1906, Heft I, p. 21); but even on this basis it is only 22 per cent in the English textile industries, as against 38 per cent in the German textile industries.
97.In England the marriage-rate fell rather sharply in 1875, and showed a slight tendency to rise about 1900 (G. Udny Yule, "On the Changes in the Marriage-and Birth-rates in England and Wales," Journal of the Statistical Society, March, 1906). On the whole there has been a real though slight decline. The decline has been widespread, and is most marked in Australia, especially South Australia. There has, however, been a rise in the marriage-rate in Ireland, France, Austria, Switzerland, Germany, and especially Belgium. The movement for decreased child-production would naturally in the first place involve decreased marriage, but it is easy to understand that when it is realized the marriage is not necessarily followed by conception this motive for avoiding marriage loses its force, and the marriage-rate rises.
