“You have a vast amount of wealth employed in an army and a navy. The cavalry horses require feed; the man-of-war requires timber for its construction; your fortifications, your arsenals, your guns, your navy, etc., all require material which is largely produced by the land surface. Their construction requires a vast amount of unproductive labor--a physiological waste which must be repaired by food. Then, again, you often destroy by war countless millions of wealth; in fact you sometimes devastate whole countries. We have no war, no armies and navies to support, no destruction of wealth by war. You have to raise food for the reparation of the waste caused by your immense amount of unproductive and destructive labor. You, as well as we, require an immense amount of power to do the work: to build the houses, to plow, sow, and harvest, to heat the apartments, to run the train and factory. You raise and feed thousands and millions of draft-animals, horses, oxen, and mules, which draw the plow, wagon, etc., for you; they all have to be fed with feed which is raised on the _surface_ of the earth, and which requires land area for its production. We have no draft-animals to feed--no hay and corn to raise for them. We receive all our motive power from the atmospheric current and water power. Thus man, during his different stages of physical and intellectual advancement, employs different motive power. Let us illustrate. “In his primitive beginning, man carries his few burdens for transportation on his back. Then he makes his slaves do it. Further on, he uses the back of his domestic animals, which have to live from the vegetable products of the earth; this, as I have said, requires land area, and man by his labor must also aid in the successful production of this feed. A little further on he uses the _direct_ wind power for propelling his clumsy ship and for running his primitive mill. Now he had power when the wind blew and none when it was calm; it was all uncertainty and irregularity. To overcome these, he invents a powerful steam engine which runs his ships, trains, factories, etc. But these engines require an immense quantity of water and fuel. This water is often difficult to get, and the fuel has to be raised on the land surface in the form of timber, or it has to be mined out of the earth; either method requires millions of days of labor. Still a little later on, man learns how to store up electricity and successfully compress air by the action of the atmospheric currents and water power. He lays up a large supply of this motive power for future use, and for unforeseen emergencies. This laid up motive power in the form of stored electricity and compressed air, he can, at his pleasure, convert into uniform mechanical motion. He applies it to his ships, trains, factories, land engines, vehicles, and all other machinery. He uses it for heating and lighting purposes, for drying and curing his grain and
