A record of soil, water, forest, animal, bird and mineral conservation. Why it has become necessary and what it is and what should be done about it. Traces the reasons for waste, new country expansion, growth of agriculture and industry. Shows natural resource conservation as a means of saving the people. A sort of ""deserts-and-everything-else-on-the-march"" with an optimistic note on the future. Timely, interesting -- shows just cause for mounting expenses to save resources while there is time.
