by year, the number of mouths to feed multiplies even faster, and
unless more land is tilled and all land cultivated more intensively, we
shall eat less and less, as a race, and pay more and more for what we eat.
Here is opportunity for the men of bone and muscle--opportunity for
health, prosperity, usefulness to humanity, enjoyment and happiness. Other
opportunities lie in the conservation of our forests and the planting and
development of new timber lands; in the building up of new industries for
manufacturing our raw materials; in restoring the American flag to the
seas of the world; in extending our foreign trade; in opening and
operating inland waterways; in irrigating or draining our millions of
square miles of land now lying idle; in the development of Alaska, and the
harnessing of our great mines of "white coal"--water-power.

Our foreign trade requires men of this type to travel in all parts of the
world as commercial ambassadors, diligently collecting, compiling, and
sending back to the United States information necessary in manufacturing
goods for foreign consumption; also information regarding credits, prices,
shipping, packing--in short, complete and detailed knowledge about
commerce with foreign lands, how to secure it and how to hold it.

The world's greatest opportunities to-day, perhaps, lie within the grasp
of the men of this active type. Instead of pioneering in exploration, as
in former years, they are needed to pioneer in production. From the
earliest history of the race, these restless men have been faring westward
and ever westward, adding to the wealth and resources of humanity by
opening up new lands. But the crest of the westward moving tide has now
circumnavigated the globe, and the Far West meets the Far East on the
Pacific Ocean. Here and there are comparatively small, neglected tracts of
land still to be developed, but there are no longer great new empires, as
in former days. The great welling sources of human life have not ceased to
flow, even though the final boundaries of its spread have been reached.
Population will continue to grow and its demands upon the resources of the
earth to increase. The man who discovers a way to make a hundred bushels
of wheat grow on an acre of land where only twenty-five bushels grew
before is as great a benefactor of the race as the discoverer of a
continent. The invention of the electric light, the telephone, the
automobile, the trolley car, and the aeropl
