If the opinion of Julius Hensel on the subject of fertilizers proves correct, it will mean a revolution in the theory of fertilization, and a complete saving of the expenses now made for the importation of fertilizers, amounting for guano and Chile saltpeter to from 80 to 100 million marks a year.[202] Hensel makes the emphatic claim, and produces numerous proofs of the correctness of his views, that the mineral of our mountains contain an inexhaustible supply of the best fertilizing stuffs. Granite, porphyry, basalt, broken and ground up, spread upon the fields or vineyards and furnished with a sufficiency of water, furnished a fertilizer that excelled all others, even animal and human refuse.[203] These minerals, he claims, contain all the elements for the cultivation of plants: potash, chalk, magnesia, phosphoric, sulphuric and silicic acids, and also hydrochlorides. According to Hensel, the Sudeton, Riesen, Erz, Tichtel, Hartz, Rhone, Vogel, Taunus, Eisel and Weser mountains, the woods of Thuringen, Spessart and Oden had an inexhaustible supply of fertilizers. It will be literally possible to "make bread out of stones." The dust and dirt of our highways also are, according to Hensel, inexhaustible sources of the same blessing. In this matter we are laymen and can not test the correctness of Hensel's theories; a part of them, however, sound most plausible. Hensel charges the manufacturers of and dealers in artificial fertilizers with hostility to his discovery and with systematic opposition, because they would suffer great loss.
According to Heider, a healthy adult secretes on an average 48.8 kilograms of solid and 438 of liquid matter a year. Estimated by the present standard of the prices of manure, and if utilized without loss by evaporation, etc., this offal represents a money value of 11.8 marks. Calculating the population of Germany to be 50,000,000 in round figures, and estimating the average value of the human offal at 8 marks, the sum of 400,000,000 marks is obtained, which now is almost totally lost to agriculture, owing to the present imperfect methods for utilizing it. The great difficulty in the way of a full utilization of these stuffs lies in the establishment of proper and extensive provisions for their collection, and in the cost of transportation. Relatively, this cost is now higher than the importation of guano from far-away transmarine deposits, which, however, decline in mass in the measure that the demand increases. Every living being, however, casts off regularly an annual supply of manure about enough for a field that yields food for one person. The enormous loss is obvious. A large portion of the city excrement runs out into our rivers and streams, and pollutes them. Likewise is the refuse from kitchens and factories, also serviceable as manure, recklessly squandered.
Future society will find means and ways to stop this waste. What is done to-day in this direction is mere patchwork, and utterly inadequate. As an illustration of what could be done to-day, may be cited the canalization and the laying out of vast fields in the capital of the Empire, on whose value, however, experts are of divided opinion. Socialist society will solve the question more easily, due, in a great measure, to the fact that large cities will gradually cease to exist, and population will decentralize.
No one will regard our modern rise of metropoles as a healthy phenomenon. The modern system of manufacture and production in general, steadily draws large masses of the population to the large cities.[204] There is the seat of manufacture and commerce; there the avenues of communication converge; there the owners of large wealth have their headquarters, the central authorities, the military staffs, the higher tribunals. There large institutions rear their heads—the academies of art, large pleasure resorts, exhibitions, museums, theaters, concert halls, etc. Hundreds are drawn thither by their professions, thousands by pleasure, and many more thousands by the hope of easier work and an agreeable life.
But, speaking figuratively, the rise of metropolitan cities makes the impression of a person whose girth gains steadily in size, while his legs as steadily become thinner, and finally will be unable to carry the burden. All around, in the immediate vicinity of the cities, the villages also assume a city aspect, in which the proletariat is heaped up in large masses. The municipalities, generally out of funds, are forced to lay on taxes to the utmost, and still remain unable to meet the demand made upon them. When finally they have grown up to the large city and it up to them, they rush into and are absorbed by it, as happens with planets that have swung too close to the sun. But the fact does not improve the conditions of life. On the contrary, they grow worse through the crowding of people in already overcrowded spaces. These gatherings of masses—inevitable under modern development, and, to a certain extent, the raisers of revolutionary centers,—will have fulfilled their mission in Socialist society. Their gradual dissolution then becomes necessary: the current will then run the other way: population will migrate from the cities to the country: it will there raise new municipalities corresponding with the altered conditions, and they will join their industrial with their agricultural activities.
So soon as—due to the complete remodeling and equipment of the means of communication and transportation, and of the productive establishments, etc., etc.—the city populations will be enabled to transfer to the country all their acquired habits of culture, to find there their museums, theaters, concert halls, reading rooms, libraries, etc.—just so soon will the migration thither set in. Life will then enjoy all the comforts of large cities, without their disadvantages. The population will be housed more comfortably and sanitarily. The rural population will join in manufacturing, the manufacturing population in agricultural pursuits,—a change of occupation enjoyed to-day by but few, and then often under conditions of excessive exertion.
As on all other fields, bourgeois society is promoting this development also: every year new industrial undertakings are transferred to the country. The unfavorable conditions of large cities—high rents and high wages—drive many employers to this migration. At the same time, the large landlords are steadily becoming industrialists—manufacturers of sugar, distillers of liquor, beer brewers, manufacturers of cement, earthen wares, tiles, woodwork, paper goods, etc. In the new social order offal of all sorts will then be easily furnished to agriculture, especially through the concentration of production and the public kitchens. Each community will, in a way, constitute a zone of culture; it will, to a large extent, itself raise its necessaries of life. Horticulture, perhaps the most agreeable of all practical occupations, will then reach fullest bloom. The cultivation of vegetables, fruit trees and bushes of all nature, ornamental flowers and shrubs—all offer an inexhaustible field for human activity, a field, moreover, whose nature excludes machinery almost wholly.
Thanks to the decentralization of the population, the existing contrast and antagonism between the country and the city will also vanish.
The peasant, this Helot of modern times, hitherto cut off from all cultural development through his isolation in the country, now becomes a free being because he has fully become a limb of civilization.[205] The wish, once expressed by Prince Bismarck, that he might see the large cities destroyed, will be verified, but in a sense wholly different from that which he had in mind.[206]
