Land planning has become in our country the proper thing to do. Planning for land use is not a new procedure in many sections of the nation. The name only is new. We have adopted various means of designating specifically the use of areas of rural land. For many years there have been areas quarantined to prevent spread of animal or plant diseases; game preserves are older than some of the states; herd district areas were early formulated on the open range; more than half a century ago areas of land were set aside for their natural phenomena and reserved for public use; and, of course, all of us are accustomed to the forest areas being established for the growing of timber.
