The natural resources of the United States are necessary to the prosperity of the people. The preservation and economic use of these resources are of vast importance. The natural resources of the world were, however, as great five thousand years ago as they are today. The soil was no less fertile then than now. The difference between the prosperity of the human race at these two periods is caused by a difference in human motive and efficiency. It is the result of ideals and knowledge. Sit at the banquet table with men who are the real powers in shaping the affairs of the world. The chances are that the champagne remains untouched. These men are not in the habit of partaking of midnight suppers. They must keep themselves fit for the next day's work. They have the approval and loyalty of their wives because they deserve it. In other words, the men who do the world's work are not drunkards. They are not gluttons. They are not libertines. They are efficient because they have healthy bodies and clean minds. It is this efficiency which the critic from Argentina saw when he said, "I do not look upon the people of the United States as a nation, but as a new civilization." ---------------------------------------------------------------------- STANDARD BOOKS PUBLISHED BY ORANGE JUDD COMPANY NEW YORK CHICAGO ASHLAND BUILDING People's Gas Building 315-321 Fourth Avenue 150 Michigan Avenue ---------- _Any of these books will be sent by mail, postpaid, to any part of the world, on receipt of catalog price.
