An experienced illustrator and writer of non-fiction for this age group gives a splendidly organized and suggestive tally of conservation in our country. Beginning with the premise that the United States was founded on the freedom to make its own mistakes as well as to pursue happiness and liberty, he proceeds to show historically one of our bigest wrongs-long range wastage of land, forest, animal and mineral resources. Then by graphic textual and pictorial cross-sectioning, he contrasts two hypothetical present day towns. In Muddyflow lack of foresight about reforestation, flood control, contour plowing, etc. -- have resulted in poverty. Cleargood is an example of the opposite policy. Further on the positive side are the last chapters dealing with what the country has done for conservation in the way of national parks and game reserves and the many things you, the reader, can do for conservation whether in the city or the country.
