The cultivation of fruits, berries and garden vegetables will reach a development hardly thought possible. How unpardonably is being sinned at present in these respects, a look at our orchards will show. They are generally marked by a total absence of proper care. This is true of the cultivation of fruit trees even in countries that have a reputation for the excellence of these; Wurtemberg, for instance. The concentration of stables, depots for implements and manure and methods of feeding—towards which wonderful progress has been made, but which can to-day be applied only slightly—will, when generally introduced, materially increase the returns in raising cattle, and thereby facilitate the procurement of manure. Machinery and implements of all sorts will be there in abundance, very differently from the experience of ninety-nine one hundredths of our modern farmers. Animal products, such as milk, eggs, meat, honey, hair, wool, will be obtained and utilized scientifically. The improvements and advantages in the dairy industry reached by the large dairy associations is known to all experts, and ever new inventions and improvements are daily made. Many are the branches of agriculture in which the same and even better can be done. The preparation of the fields and the gathering of the crops are then attended to by large bodies of men, under skilful use of the weather, such as is to-day impossible. Large drying houses and sheds allow crops being gathered even in unfavorable weather, and save losses that are to-day unavoidable, and which, according to v. d. Goltz, often are so severe that, during a particularly rainy year, from eight to nine million marks worth of crops were ruined in Mecklenburg, and from twelve to fifteen in the district of Koenigsberg.
Through the skilful application of artificial heat and moisture on a large scale in structures protected from bad weather, the raising of vegetables and all manner of fruit is possible at all seasons in large quantities. The flower stores of our large cities have in mid-winter floral exhibitions that vie with those of the summer. One of the most remarkable advances made in the artificial raising of fruit is exemplified by the artificial vineyard of Garden-Director Haupt in Brieg, Silesia, which has found a number of imitators, and was itself preceded long before by a number of others in other countries, England among them. The arrangements and the results obtained in this vineyard were so enticingly described in the "Vossische Zeitung" of September 27, 1890, that we have reproduced the account in extracts:
"The glass-house is situated upon an approximately square field of 500 square meters, i. e., one-fifth of an acre. It is 4.5 to 5 meters high, and its walls face north, south, east and west. Twelve rows of double fruit walls run inside due north and south. They are 1.8 meters apart from each other and serve at the same time as supports to the flat roof. In a bed 1.25 meters deep, resting on a bank of earth 25 centimeters strong and which contains a net of drain and ventilation pipes,—a bed 'whose hard ground is rendered loose, permeable and fruitful through chalk, rubbish, sand, manure in a state of decomposition, bonedust and potash'—Herr Haupt planted against the walls three hundred and sixty grape vines of the kind which yields the noblest grape juice in the Rhinegau:—white and red Reissling and Tramine, white and blue Moscatelle and Burgundy.
"The ventilation of the place is effected by means of large fans, twenty meters long, attached to the roof, besides several openings on the side-walls. The fans can be opened and shut by means of a lever, fastened on the roof provided with a spindle and winch, and they can be made safe against all weather. For the watering of the vines 26 sprinklers are used, which are fastened to rubber pipes 1.25 meters long, and that hang down from a water tank. Herr Haupt introduced, however, another ingenious contrivance for quickly and thoroughly watering his 'wine-hall' and his 'vineyard', to wit, an artificial rain producer. On high, under the roof, lie four long copper tubes, perforated at distances of one-half meter. The streams of water that spout upward through these openings strike small round sieves made of window gauze and, filtered through these, are scattered in fine spray. To thoroughly water the vines by means of the rubber pipes requires several hours. But only one faucet needs to be turned by this second contrivance and a gentle refreshing rain trickles down over the whole place upon the grape vines, the beds and the granite flags of the walks. The temperature can be raised from 8 to 10 degrees R. above the outside air without any artificial contrivance, and simply through the natural qualities of the glass-house. In order to protect the vines from that dangerous and destructive foe, the vine louse, should it show itself, it is enough to close the drain and open all the water pipes. The inundation of the vines, thus achieved, the enemy can not withstand. The glass roof and walls protect the vineyard from storms, cold, frost and superfluous rain; in cases of hail, a fine wire-netting is spread over the same; against drought the artificial rain system affords all the protection needed. The vine-dresser of such a vineyard is his own weather-maker, and he can laugh at all the dangers from the incalculable whims and caprices of indifferent and cruel Nature,—dangers that ever threaten with ruin the fruit of the vine cultivator.
"What Herr Haupt expected happened. The vines thrived remarkably under the uniformly warm climate. The grapes ripened to their fullest, and as early as the fall of 1885 they yielded a juice not inferior to that generally obtained in the Rhinegau in point of richness of sugar and slightness of sourness. The grapes thrived equally the next year and even during the unfavorable year of 1887. On this space, when the vines have reached their full height of 5 meters, and are loaded with their burden of swollen grapes, 20 hectoliters of wine can be produced yearly, and the cost of a bottle of noble wine will not exceed 40 pennies.
"There is no reason imaginable why this process should not be conducted upon a large scale like any other industry. Glass-houses of the nature of this one on one-fifth of an acre can be undoubtedly raised upon a whole acre with equal facilities of ventilation, watering, draining and rain-making. Vegetation will start there several weeks sooner than in the open, and the vine-shoots remain safe from May frosts, rain and cold while they blossom; from drought during the growth of the grapes; from pilfering birds and grape thieves and from dampness while they ripen; finally from the vine-louse during the whole year and can hang safely deep into November and December. In his address, held in 1888 to the Society for the Promotion of Horticulture, and from which I have taken many a technical expression in this description of the 'Vineyard', the inventor and founder of the same closed his words with this alluring perspective of the future: 'Seeing that this vine culture can be carried on all over Germany, especially on otherwise barren, sandy or stony ground, such as, for instance, the worst of the Mark, that can be made arable and watered, it follows that the great interests in the cultivation of the soil receive fresh vigor from "vineyards under glass." I would like to call this industry "the vineyard of the future".'
"Just as Herr Haupt has furnished the practical proof that on this path an abundance of fine and healthy grapes can be drawn from the vine, he has also proved by his own pressing of the same what excellent wine they can yield. More thorough, more experienced, better experts and tried wine-drinkers and connoisseurs than myself have, after a severe test, bestowed enthusiastic praise upon the Reissling of the vintage of '88, upon the Tramine and Moscatelle of the vintage of '89, and upon the Burgundy of the vintage of '88, pressed from the grapes of this 'vineyard'. It should also be mentioned that this 'vineyard' also affords sufficient space for the cultivation of other side and twin plants. Herr Haupt raises between every two vines one rose bush, that blossoms richly in April and May; against the east and west walls he raises peaches, whose beauty of blossom must impart in April an appearance of truly fairy charm to this wine palace."
The enthusiasm with which the reporter describes this artificial "vineyard" in a serious paper testifies to the deep impression made upon him by this extraordinary artificial cultivation. There is nothing to prevent similar establishments, on a much more stupendous scale and for other branches of vegetation. The luxury of a double crop is obtainable in many agricultural products. To-day all such undertakings are a question of money, and their products are accessible only to the privileged classes. A Socialist society knows no other question than that of sufficient labor-power. If that is in existence, the work is done in the interest of all.
Another new invention on the field of food is that of Dr. Johann Hundhausen of Hamm in Westphalia, who succeeded in extracting the albumen of wheat—the secret of whose utilization in the legume was not yet known—in the shape of a thoroughly nutritive flour. This is a far-reaching invention. It is now possible to render the albumen of plants useful in substantial form for human food.
The inventor erected a large factory which produces vegetal albumen or aleurone meal from 80 to 83 per cent. of albumen, and a second quality of about 50 per cent. That the so-called aleurone meal represents a very concentrated albuminous food appears from the following comparison with our best elements of nourishment:
