The Andes of southern Peru . is no vegetation whatever. An exception is the CoastEange,(not shown on these small maps, but exhibited in the suc-ceeding diagram. These have moderate rains on their seaward(westerly) slopes during some years and grass and shrubbyvegetation grow between the arid coastal terraces below themand the parched desert above. The greatest variety of climate isenjoyed by the mountain zone. Its deeper valleys and basins de-scend to tropical levels; its higher ranges and peaks are snow-cov-ered. Between are the climates of half the world compressed, itmay be, between 6,000 and 15,000 feet of elevation and with ex-tremes only a days journey apart. In the explanation of these contrasts we have to deal with rela-tively simple facts and principles; but the reader who is interestedchiefly in the human aspects of the region should turn to p. 138where the effects of the climate on man are set forth.
