Excerpt from Geography of the Central Andes: A Handbook to Accompany the La Paz Sheet of the Map of Hispanic America on the Millionth Scale This regional account of an important part of the Central Andes and the first (provisional) edition of the map representing the area have been compiled simultaneously as the result of an effort to draw together much scattered information. Materials for map and book have been gathered from sources which vary widely in character and Quality. The data utilized in the map, and the method of its construction, are discussed in some detail in Part I. The bibliography records most of the sources of mate rial for the book. Existing scientific data are probably above the average for South American areas of this extent in both quantity and quality; but, as a rule, they relate only to small parts of the country. Moreover, we can turn to no systematic description of the whole territory covered by the map. And modern geography requires more than mere description; it demands that genetic relationships be brought out. This fact has been kept in view in writing a book which, because of the present state of knowledge, is a provisional edition, like the map that it accompanies. The reader will quickly appreciate that within the area dis cussed there are several strongly contrasted natural regions, and he will surely ask himself what is the total extent of each. For, in fact, all of the more important of them extend far beyond the map limits. A diagram has therefore been placed at the end of Chapter I showing the relation of the various natural regions discussed to the sheets of the millionth map in general and to the La Paz sheet in particular. Thus it will be seen that many of the general observations which are made in this handbook would apply equally well in the description of a number of different map areas.
