As a matter of fact, if we put aside those gardeners who chiefly cultivate the so-called primeurs—strawberries ripened in January, and the like—if we take only those who grow their crops in the open field, and resort to frames exclusively for the earlier days of the life of the plant, and if we analyse their system, we see that its very essence is, first, to create for the plant a nutritive and porous soil, which contains both the necessary decaying organic matter and the inorganic compounds; and then to keep that soil and the surrounding atmosphere at a temperature and moisture superior to those of the open air. The whole system is summed up in these few words. If the French maraîcher spends prodigies of labour, intelligence, and imagination in combining different kinds of manure, so as to make them ferment at a given speed, he does so for no purpose but the above: a nourishing soil, and a desired equal temperature and moisture of the air and the soil. All his empirical art is devoted to the achievement of these two aims. But both can also be achieved in another and much easier way. The soil can be improved by hand, but it need not be made by hand. Any soil, of any desired composition, can be made by machinery. We already have manufactures of manure, engines for pulverising the phosphorites, and even the granites of the Vosges; and we shall see manufactures of loam as soon as there is a demand for them.

It is obvious that at present, when fraud and adulteration are exercised on such an immense scale in the manufacture of artificial manure, and the manufacture of manure is considered as a chemical process, while it ought to be considered as a physiological one, the gardener prefers to spend an unimaginable amount of labour rather than risk his crop by the use of a pompously labelled and unworthy drug. But that is a social obstacle which depends upon a want of knowledge and a bad social organisation, not upon physical causes.[63]

Of course, the necessity of creating for the earlier life of the plant a warm soil and atmosphere will always remain, and sixty years ago Léonce de Lavergne foretold that the next step in culture would be to warm the soil. But heating pipes give the same results as the fermenting manures at a much smaller expense of human labour. And already the system works on a large scale, as will be seen from the next chapter. Through it the productive powers of a given area of land are increased more than a hundred times.

It is obvious that now, when the capitalist system makes us pay for everything three or four times its labour value, we often spend about £1 for each square yard of a heated conservatory. But how many middlemen are making fortunes on the wooden sashes imported from Drontheim? If we only could reckon our expenses in labour, we should discover to our amazement that, thanks to the use of machinery, the square yard of a conservatory does not cost more than half a day of human labour; and we will see presently that the Jersey and Guernsey average for cultivating one acre under glass is only three men working ten hours a day. Therefore the conservatory, which formerly was a luxury, is rapidly entering into the domain of high culture. And we may foresee the day when the glass conservatory will be considered as a necessary appendix to the field, both for the growth of those fruits and vegetables which cannot succeed in the open air, and for the preliminary training of most cultural plants during the earlier stages of their life.

Home-grown fruit is always preferable to the half-ripe produce which is imported from abroad, and the additional work required for keeping a young plant under glass is largely repaid by the incomparable superiority of the crops. As to the question of labour, when we remember the incredible amount of labour which has been spent on the Rhine and in Switzerland for making the vineyards, their terraces, and stone walls, and for carrying the soil up the stony crags, as also the amount of labour which is spent every year for the culture of those vineyards and fruit gardens, we are inclined to ask, which of the two, all taken, requires less of human labour—a vinery (I mean the cold vinery) in a London suburb, or a vineyard on the Rhine, or on Lake Leman? And when we compare the prices realised by the grower of grapes round London (not those which are paid in the West-end fruit shops, but those received by the grower for his grapes in September and October) with those current in Switzerland or on the Rhine during the same months, we are inclined to maintain that nowhere in Europe, beyond the forty-fifth degree of latitude, are grapes grown at less expense of human labour, both for capital outlay and yearly work, than in the vineries of the London and Brussels suburbs.

At any rate, let us not overrate the productivity of the exporting countries, and let us remember that the vine-growers of Southern Europe drink themselves an abominable piquette; that Marseilles fabricates wine for home use out of dry raisins brought from Asia; and that the Normandy peasant who sends his apples to London, drinks real cider only on great festivities. Such a state of things will not last for ever; and the day is not far when we shall be compelled to look to our own resources to provide many of the things which we now import. And we shall not be the worse for that. The resources of science, both in enlarging the circle of our production and in new discoveries, are inexhaustible. And each new branch of activity calls into existence more and more new branches, which steadily increase the power of man over the forces of nature.

If we take all into consideration; if we realise the progress made of late in the gardening culture, and the tendency towards spreading its methods to the open field; if we watch the cultural experiments which are being made now—experiments to-day and realities to-morrow—and ponder over the resources kept in store by science, we are bound to say that it is utterly impossible to foresee at the present moment the limits as to the maximum number of human beings who could draw their means of subsistence from a given area of land, or as to what a variety of produce they could advantageously grow in any latitude. Each day widens former limits, and opens new and wide horizons. All we can say now is, that, even now, 600 persons could easily live on a square mile; and that, with cultural methods already used on a large scale, 1,000 human beings—not idlers—living on 1,000 acres could easily, without any kind of overwork, obtain from that area a luxurious vegetable and animal food, as well as the flax, wool, silk, and hides necessary for their clothing. As to what may be obtained under still more perfect methods—also known but not yet tested on a large scale—it is better to abstain from any forecast: so unexpected are the recent achievements of intensive culture.

We thus see that the over-population fallacy does not stand the very first attempt at submitting it to a closer examination. Those only can be horror-stricken at seeing the population of this country increase by one individual every 1,000 seconds who think of a human being as a mere claimant upon the stock of material wealth of mankind, without being at the same time a contributor to that stock. But we, who see in each new-born babe a future worker capable of producing much more than his own share of the common stock—we greet his appearance.

We know that a crowded population is a necessary condition for permitting man to increase the productive powers of his labour. We know that highly productive labour is impossible so long as men are scattered, few in numbers, over wide territories, and are thus unable to combine together for the higher achievements of civilisation. We know what an amount of labour must be spent to scratch the soil with a primitive plough, to spin and weave by hand; and we know also how much less labour it costs to grow the same amount of food and weave the same cloth with the help of modern machinery.

We also see that it is infinitely easier to grow 200,000 lb. of food on one acre than to grow them on ten acres. It is all very well to imagine that wheat grows by itself on the Russian steppes; but those who have seen how the peasant toils in the “fertile” black earth region will have one desire: that the increase of population may permit the use of the steam-digger and gardening culture in the steppes; that it may permit those who are now the beasts of burden of humanity to raise their backs and to become at last men.
