When the suggestion is made from the Department of Agriculture that all that science has yet accomplished has been to stop a tendency to a lessened production from the land now under the plow, and when it is even suggested that in 1930 the present meager average of crops per acre may still exist, it seems to me that little credit is given to the good work already accomplished in the short period in which the separate Department of Agriculture has been represented in the Cabinet, especially in the last five or six years, while the suggestion itself shows very little consideration of the great work of the experiment stations.

Unless it can be proved that my correspondents and myself have entered into a conspiracy to mislead the public in dealing with the potential of this country in wheat production, nearly all the deductions from the figures of the past must be considered mere statistical rubbish. These statistics cover sections and States in which wheat should never be grown or attempted in competition with the true wheat soils and climate. As well might misplaced iron furnaces, built to boom city lots where there are no favorable conditions for the production of iron, be included in an average and held up as a standard of our potential in iron and steel production.

In my efforts to discover the rule of progress in the arts and occupations of the people of this country, it has become plain that in ratio to the application of science and invention to every art the quantity of product is increased, the number of workmen is relatively diminished, the price of the product tends to diminish, while the wages or earnings of those who do the work are augmented. I have investigated many branches of industry, and find evidence conclusive to my own mind that such is the law of industrial development. This rule is subject to temporary variations under the restriction of statutes. In my own judgment, the so-called protective principle or policy of interference with commerce by imposing fines on foreign imports has retarded the progress of the specially protected arts, and has in some measure obstructed the diversity of manufactures; but the opposite policy of absolutely free trade in our domestic traffic over a greater area and among a much larger number of people than have elsewhere secured their own liberty has been so much more potent in its progressive influence as to have lessened the evils of the restrictions on foreign trade.

According to my observation, all the efforts to regulate railroad charges by State legislation and under the interstate commerce act have greatly retarded the progress of the railway, and have deprived great States, notably Texas, of any service at all commensurate to the demand which might otherwise have been supplied to the mutual benefit of the owners of the railways and the inhabitants of the State. The most serious retarding influence, especially evil in its effect upon farmers, was the useless panic of 1893, caused by the silver craze—that is to say, by the effort to enact a force bill by which the producers of our great crops would have been compelled to accept money of half the purchasing power of that to which their industry had been long adjusted. This caused a temporary paralysis of industry, in which I think none suffered so much as the farmers of the country.

But admitting these temporary variations, I find the same rule governing the products of the farm that governs the mine, the factory, and the workshop—namely, a lessening of the number occupied in ratio to the product; a great reduction in the cost of labor; an increased return in due proportion of the skill and intelligence of the farmer; a rapid reduction in the farm mortgages, ending at the present date in making the farmers of the grain-growing States the creditors of the world, especially those occupied upon wheat.

But in the development of this progress we find the reverse of the practice in the factory and the workshop. The most important applications of science and invention led first to what might be called the manufacture of wheat on an extensive method of making a single crop on great areas of land. That phase has about spent its force; the great farms are in process of division; the single-crop system has about ended; the intensive system of making a larger product from a lessened area with alternation and variation in crops is rapidly taking the place of former methods.

Therefore, while many branches of manufacturing tend more and more to the collective method, the tendency in agriculture is more and more to individualism in dealing with the land itself, coupled with collective ownership in the more expensive farm machinery, in creameries, cheese factories, and the like. We are apparently at a halfway stage in this revolution of agriculture. The intelligent and intensive methods of breeding cattle and sheep is also rapidly taking the place of the semibarbarous conditions of the ranch.

If these points are well taken, the very suggestion that we must compute the land which should be under the plow in 1890 in order to supply the needs of 130,000,000 people on the basis of the imperfect statistics and inadequate data of the past, becomes almost an impertinence. It is much more probable that the 400,000 square miles which now meet the needs of 75,000,000 people, with an enormous excess for export, will in 1930 still suffice for the domestic supply of 130,000,000 people, with a proportionate export corresponding to the present.

If the product of the farms of the West now yielding the largest crops, or of the renovated lands of the South now yielding the best crops, be taken as the average standard of the near future, as they should be, then it may be true in 1930, as it is now, that one fifth of the arable land of this country when put under the plow will still suffice for all existing demands, the remainder of our great domain extending the promise of future abundance and welfare to the yet greater numbers who will occupy the land a century hence.

I may add that in the course of a very friendly correspondence with Sir William Crookes, while we are still at variance in our estimates of the area which may be converted to the production of wheat in this country without trenching upon any other product, we are wholly at an agreement on a most material point. I quote from one of his letters: "Under the present wasteful method of cultivation there will be in a limited number of years an insufficient supply of wheat. Apply artificial fertilizers judiciously, and the supply may be increased indefinitely." I would only venture to add to the judgment of so eminent a writer the words "or natural," to the end that the paragraph should read, "Apply artificial or natural fertilizers judiciously, and the supply can be increased indefinitely."
