This bears many resemblances to Katherine Carr's South American Primer (See May 15th issue, page 196 -- published by Reynal & Hitchcock, 6/16), is a bit more scare-heady but contains the same prescription for a more interested, friendly and cooperative understanding on the part of North America, in order to insure a united front. Again an interpretative study of the countries to the South, including Mexico; current problems and prominent characters, straws indicating which way the wind blows; emphasis on the fascist countries' colonization policies. Both books are good, both readable, intelligent, filled with human interest bits, sound in factual content. The Carr is more conservative; the Whitaker more extreme.
