It does not seem possible that this great lesson can be forgotten by our generation. Perhaps this is the largest result that the war will yield within the field of rural interests. National leaders as never before will consider every possible method by which farming can be made profitable, satisfying, and socially appreciated. This policy will be undertaken not merely for the sake of the farmer, but also as a means of providing national safety. The war already has disclosed the tendency of national policy to regard the uses made of farming land as a matter for social concern. In England, France, and Germany especially we have had, as a result of war conditions, public control exercised regarding the uses made of private land. Certain crops have been outlawed. Others have been stimulated and encouraged by the action of the government. It has proved wise to establish this control over the uses made of productive land. Of course, war has furnished the motive and made possible the success of this practical public control of land resources. Indeed, before the war, no one could have imagined that England, for example, could have been led to so great a public control of the uses of productive land as has already resulted from the war. Already we find some people advocating that the government continue after the war to exercise a degree of such control over the uses made of private lands and it attempt to conserve national safety by stimulating the production of staple crops. At least for a time it will be difficult to win converts to the proposition that the public has no interest in what people who own productive land may do with their property. By education, if not by legislation, the wiser nations are likely to attempt consciously to direct production for social welfare. Probably some nations will not hesitate to subsidize the cultivation of certain crops in order to keep agriculture in a condition of preparedness for the trials of war.
