Steam, explosives, electricity—the factors which have madethe world what it is to-day—were indispensable for the railroadand the steamboat, the factory and the mine, but the farmers workwas generally run on a comparatively small scale, and was mostlydone by the muscles of men or draft animals. To-day, however, the farmer, as well as the manufacturer, the contractor and the miner, fully appreciates the value of labor-saving devices. Every up-to-datefarm, large or small, has modern machinery that tends to reducethe cost of production or to improve farm products. Explosives were first used in warfare and hunting, then forblasting.
