To-day the manure question is one of the most important considerations of the time. The virgin soil of the prairies, of the cleared woodlands and of the broken-up ranges, for a few years produced immense crops of cotton and grain. To build up the decreasing productiveness of the fields the farmer soon learned that barnyard manure was the best thing at hand. The passing of the cattle ranch and the resulting higher price of meats made stock raising very profitable even to the small farmer, especially since feeding floors made it possible for him to return to the soil, in the form of manure, all the fertility which had been removed in the growing of grain. Leaving out the matter of foods, the strength of manure is dependent directly upon its manner of storage. Manure piled on the bare ground or in wooden pens loses one-third to one-half of its fertilizing properties on account of leaching, due to heavy rains and tramping of the stock, and later because of fermentation or “firing” brought about by the lack of sufficient moisture. This fertilizer usually sells at from 75 cents to $1.00 per load.
The farmer of to-day builds a water-tight concrete cistern or pit in which he stores the manure and keeps it as moist as need be. He extended the concrete floors to the dairy barns with the result that they were so clean, so odorless and so sanitary that state inspection is now often insisting and will soon force careless dairymen to put in such floors as a means of protecting the public health from disease germs carried in unclean milk. The drop gutters carry all the liquids, the richest part of the manure, formerly wasted, to the manure pits. Consequently, one load of manure, thus properly preserved, is easily worth two loads as ordinarily stored. By confining the manure in pits and by paving the barn lot with concrete, the farm has been rid of the chief breeding-place of flies, gnats, mosquitos and disease. Moreover, such an interior court, surrounded by buildings and concrete wind walls, forms an excellent feed and winter exercise lot.
Government statistics show that the human death-rate on the farm, in spite of the fresh food and pure air, is greater than the death-rate in the city. State University tests of drinking-water have shown beyond a doubt that the waters of many ordinary shallow and unprotected wells contain the germs of such dangerous diseases as typhoid fever. To prevent the polluted surface waters from seeping into the well, many people are covering their wells and walling them up with water-tight concrete. Others are sinking “driven” wells and protecting them with concrete housings. The principle of deep wells for pure water, among other things, has made gasoline engines a necessity on the farm. These engines and hydraulic rams at springs, firmly set and housed in concrete, supply an abundance of water for the concrete reservoirs or elevated, reinforced pressure tanks. From these places of storage water is distributed to float-controlled, rot-proof watering tanks and troughs of the same material. With such a water supply animals never suffer for water. Even springs and mouths of drain tile are improved and the water made clean and wholesome by the use of concrete.
Thus the conservative farmer of the present time gives careful attention to the health, comfort and convenience of his family. Moreover, the care of the animals is not neglected. A concrete dipping vat holds the liquids which free horses, cattle, sheep and hogs of mange, lice, mites, ticks and fleas. The Department of Agriculture is stamping out the Texas fever and sheep scab by insisting on the use of dipping tanks throughout all quarantined districts. A hog wallow with concrete sides and bottoms gives the hog the pleasure afforded by running streams and at the same time protects him from the cholera often carried down from animals affected further up stream.
The continual rotting off of wooden fence posts, the constantly increasing cost of new ones, and the annual expense of fence repairs, called for the introduction of some substitute. Land is entirely too valuable and life too short to attempt growing wooden posts. Even before the telephone and telegraph companies had thought of the possibilities of concrete in this line, a few venturesome farmers had given reinforced concrete posts a trial and found their use not only advisable from the standpoint of cheapness in first cost, but more profitable on account of their everlasting qualities. The Department of Agriculture at Washington has thoroughly investigated the use and methods of making concrete posts and is furnishing a free bulletin describing the process. Such posts are also valuable in the culture of grapes and hops.[1]
The use of concrete in farm buildings has gradually developed from the ground upward. The drip soon rots out timber near the ground and eventually crumbles away the brick foundation. At first, uselessly making the walls as heavy as those of brick, the farmer gave concrete a trial in foundations. Concrete is stronger than brick. As a wall it kept the basement and back barn dry. The height of the foundation wall increased until it supported the joists of the hay loft. Finally, after a study of methods, of reinforcing, the entire barn—basement, walls, floors, mangers, troughs, gutters, beams and even the shingles—became concrete. Matches or lanterns accidentally dropped on concrete floors in concrete barns do not cause the terror of former times. The oil will burn until smothered out with a horse blanket, but no further damage will be done.
Poultry raising on many farms has become well-nigh impossible on account of rats. To free the farm of these destructive animals, as a last resort and in spite of the assertions that the grain would spoil, the thoroughly provoked farmer put concrete floors under his cribs and granaries. Corn matured enough not to spoil on other floors kept perfectly on concrete. The rats had to go; they could not get through such floors. And so we might continue, describing how farmers have successfully used concrete in building every class of structure from a stepping stone to the entire group of farm buildings.
Just as there are right and wrong methods of farming, so, too, are there right and wrong ways of using concrete. It is the aim of this book to give such directions and information as will enable the reader to build with concrete surely and successfully.
“CONCRETE IN THE COUNTRY” does not pretend to fully cover the subject—the field is too large to be exhausted in one such volume. But the publishers have attempted to deal with as wide a variety of types of concrete construction as is possible in the space available.
