But let us follow more particularly the producers of the fields, whom we call the farmers there, the men whom the son of Sirach had in mind when he said in the ancient days: "How shall he become wise that holdeth the plough, that glorieth in the shaft of the goad, ... and whose discourse is of the stock of bulls?" It was a farmer's son who invented the harvester, and four-fifths of the men (whom the writer, to whom I am indebted for many of these facts about the farmer, calls "harvester kings")--along with the plough kings and wagon kings of whom democracy has been dreaming-were farmers' sons. The plough, the self-binder, the thresher were all invented on the farm. The son of Sirach said: "They shall not be sought for in the council of the people, and in the assembly they shall not mount on high"; but fourteen of the first twenty-six Presidents were farmers' sons, and that statistic gives but merest suggestion of the farmer's part in all the councils of the people. Here are a few significant, graphic facts which would furnish interesting material for a new edition of Virgil's "Georgics" and "Bucolics" or lead Horace to revise his verses on rural life. There are practically five times as many farmers (under the early man- power definition of the farmer) as the census shows, for the farmer now works with the old-time power of five men. Six per cent of the human race (and the larger part of that six per cent is in the Mississippi Valley) produces, one-fifth of the wheat of the world, two-thirds of the cotton, and three fourths of the corn (and this takes no account of its reapers and mowers that gather the crops in other valleys). It would cost three hundred million dollars more to harvest the world's wheat by hand, if it were possible, than it costs now by the aid of the harvester and reaper. [Footnote: H. N. Casson, "Romance of the Reaper," p. 178.] Some years ago in a trial made in Germany in the presence of the Emperor and his ministers, it was shown that a Mississippi Valley harvester driven by one man could do more in one day than forty Polish women with old- fashioned sickles. [Footnote: H. N. Casson, "Romance of the Reaper," pp. 134, 135.] The precursor of the harvester saw grandmothers and mothers in the fields working day and night to cut and gather the harvest, but he could not now (except among the new immigrant farmers) see that spectacle. I cannot recall that, until I met that old-world population coming over the mountains as I made my first journey east out of that valley, over twenty years ago, I ever saw a woman at work in the fields.
