_Rivers, Harbors and Parks_

In addition to the vast work of reclaiming desert lands, protecting
forests, and improving rivers, harbors and canals, Uncle Sam has spent
millions of dollars in opening up to the people great natural wonder
realms of the country and putting them in order for outdoor pleasure
grounds. Four National Parks--the Yellowstone, the Yosemite, Glacier
National Park and Rainier National Park have already been treated in
individual numbers of The Mentor, and future issues will be devoted to
others of these magnificent public domains. The Grand Canyon, to which
a Mentor number has also been given, is not one of the National Parks,
but is a Reserve set apart for all time by the Government.
