In the war days we naturally ignored the _fallow_. We cultivated with Hooverian haste. It was necessary to put our soil in peril of exhaustion even as we put our men in peril of death. Forty million added acres were commandeered, six billions of bushels of the leading cereals were added to the annual product of earlier seasons. The land could be let to think only of immediate defense. Crops only could be grown which would help promptly to win the war. Vetch and clover and all else that permanently enriched must be given up for war gardening or war farming. The motto was not _Americanus sedendo vincit_ but _Americanus accelerando vincit_. But on this day of my writing (the day of the signing of the peace) I am thinking that in agriculture and in education as well, we must again turn our thoughts to the virtues of thoroughness and patience--the virtues of the fallow, that is, to ploughing and harrowing and tilling, _not_ for the immediate crop, but for the enrichment of the soil and of the mind, according as our thought is of agriculture or education. Cato, when asked what the first principle of good agriculture was, answered "To plough well." When asked what the second was, replied "To plough again." And when asked what the third was, said "To apply fertilizer." And a later Latin writer speaks of the farmer who does not plough thoroughly as one who becomes a mere "clodhopper." You will notice that it is not sowing, nor hoeing after the sowing, but ploughing that is the basic operation. It is the sowing, however, that is popularly put first in our agricultural and educational theory. "A sower went forth to sow." A teacher went forth to teach, that is, to scatter information, facts:--arithmetical, historical, geographical, linguistic facts. But the emphasis of the greatest agricultural parable in our literature was after all not on the sowing but on the soil, on that upon which or into which the seed fell,--or as it might be better expressed, upon the _fallow_. It was only the fallow ground, the ground that had been properly cleared of stones, thorns, and other shallowing or choking encumbrances, that gave point to the parable. It was the same seed that fell upon the stony, thorny, and fallow ground alike. There is a time to sow, to sow the seed for the special crop you want; but it is after you have ploughed the field. There is a time to specialize, to give the information which the life is to produce in kind; but it is when you have thoroughly prepared the mind by its ploughing disciplines.
