The production of cereals is the most important branch of agriculture, comprising corn, wheat, oats, barley, rye, buckwheat, and rice. Since the building of the trunk railroads, by which the western territory was given access to a market, the progress of cereal production has been extremely rapid, nor does there seem to be any observable slackening. With the introduction of improved varieties of spring wheat, cereal production is being pushed further up into British Canada and our own Northwest. The center of cereal production has moved steadily westward, from eastern Indiana in 1860 to eastern Iowa in 1900. With the practical exhaustion of unoccupied land suitable
for grain-raising in the United States, it is clear that the future extension of the industry depends rather upon improvements in the methods of agriculture than upon the addition of new lands. The very practical problem here presented to the American farmer if he wishes to maintain his supremacy in the world’s markets is being nobly and successfully met by the agricultural experiment stations. They are teaching the farmer how to increase his yield of wheat, for example, by scientific seed selection and more careful methods of tillage, from an average of 12.5 bushels per acre for the whole country in 1900 to treble that amount.
Of the separate crops corn is by far the most important, representing 60 per cent of the total value of all cereals produced in 1900. Most of the corn is fed to stock throughout the so-called “corn belt” and comes to market in the form of pork and beef. Although corn is very nutritious and is a favorite article of diet in this country in various forms, astonishingly little of it is exported. The development of a foreign market still awaits the enterprise of the American farmer and food manufacturer.
The production of live stock is essentially a frontier industry, and while it will probably always be carried on in the semi-arid grazing districts of the West, which can be reclaimed for agriculture only at considerable expense, it already shows a relative decline. Owing to the great growth of the population the domestic demand now consumes almost all the meat produced and the exports are declining. This is one of the reasons for the recent rise in the price of meat. The industry is extensive. Quite the opposite is true of the dairy industry, which is intensive, being carried on for the most part in the vicinity of large cities where land is expensive. The changing character of agriculture and the fact that it is itself a business enterprise demanding a knowledge of market conditions and business methods is well illustrated by the nature of the
dairy industry. Dairies are inspected and must conform to certain standards, the milk must be sterilized and shipped, often by special trains, to the cities. Over a third of the butter and practically all of the cheese is now made in factories instead of on the farm, so that it is a question whether the latter at least should not be classified as a product of manufacture rather than of agriculture.
Of the last of the four important branches of agriculture, namely cotton-raising, there is not so much to be said. Owing to the intensive nature of its cultivation, machinery has never been applied on a large scale to its production, as was done in the case of hay and grain. The wasteful methods that prevailed before the Civil War in the South have been largely corrected, and the tendency to sterility of the soil has been met by the increased use of fertilizers. The statistics of cotton crops for the past thirty years do not indicate any decrease in productiveness, and show that the point of diminishing returns has not yet been reached. A peculiar and interesting feature about cotton production is that it is largely in the hands of tenants. The old slave plantations of the South have been broken up into small holdings and many of these are operated by tenants, negroes and whites, who are too poor or too improvident to buy the land outright. The main problems connected with cotton culture are labor problems; and the question has often been anxiously asked whether the free negro will produce as much as the former slave. This can now be confidently answered in the affirmative, though it yet remains to be seen whether he can be made as efficient a producer as his white competitor. Upon the answer to that question depends not merely the future of cotton production, but the economic salvation of the negro himself. The constantly expanding use of cotton goods assures a brilliant future to the cotton-growing states of the South, for not merely is there an assured market in America and Europe, but the primitive peoples of
Asia and Africa may be depended upon to absorb increasing quantities of cotton fabrics.
Hand in hand with the heedless extensive methods of agriculture in the past went wasteful use and even destruction of our forest resources. The annual cut of lumber in the United States is today about forty billion feet board measure; at this rate of consumption it is estimated that the present available supply will last only 35 to 50 years. It will doubtless surprise most readers to learn that about three-quarters of the annual wood cut is consumed as fuel, probably half of our population still depending upon wood instead of coal for fuel. The rapid exhaustion of our forest supplies, with the attendant effects upon moisture, floods, etc., has brought the question of forest preservation to the front as a practical economic problem. We have been squandering the heritage of our children and efforts are now being made to repair some of the loss before we are declared bankrupt. In 1898 the Federal Government began practical work in the introduction of forestry; this received a great stimulus in 1905 when the care of the national forest reserves, embracing over 60,000,000 acres, was put under the control of the Forest Service. Over 150 trained foresters are employed, who manage the forests on the public lands and co-operate with private owners in the introduction of scientific forestry. Several states have taken up the movement, and there is every indication that scientific methods of culture such as prevail in Prussia and other European states, will supplant our destructive denudation of the land. That it is high time to devote attention to the better conservation of this natural resource is made evident by the high and increasing price of lumber.
There is one other natural resource the conditions of whose supply resemble those of forestry and of agriculture in general; this is the fisheries. With careful use, providing for depreciation, and restoring the elements destroyed,
all of these should prove inexhaustible and should continue to furnish man with food and lumber for all time. But as in the case of the other two industries, so with the fisheries, we have been using up our capital and declaring enormous dividends at the expense of the future. The value of the annual catch of fish is $40,000,000, which is exceeded only by that of Great Britain. The problem of the better conservation of this resource has been taken in hand by the Federal Government, through the Fish Commission, and much has been done to repair our early prodigality by restocking lakes and streams with fish. More stringent fish and game laws have also been passed by most of the states, designed to prevent the extermination of the supply.
