Show A WORLD ATLAS OF commercial GEOLOGY with the growth of american industries the known and the possible sources of our supplies of raw materials have become of greater and more pressing interest even the united states most favored of nations in abundance and variety of raw materials can not be self sufficient it must look beyond its shores for supplies as well as for markets the study of the distribution of mineral raw materials and their belai relations to the promotion of trade and an the control of industry is a branch of geology and may best be termed commercial geology under the complex requirements of present day life no continent not even north america can be self sustaining it is no longer enough for us to make an inventory of the mineral nii wealth of the united states we must supplement that inventory by a broad understanding of world demand and supply to set forth graphically and to describe concisely the basic facts concerning both the present pres e nt and the future sources of the useful minerals is the purpose of a world atlas of commercial geology just issued by the united states geological survey department of the interior the output of the essential minerals in 1913 the latest normal year may at least be regarded as a measure of the quick assets possessed by each nation and the first part of the world atlas of commercial geo logy has therefore been planned to show the distribution distribute on of mineral production in 1913 the practical value of this exhibit of the worlds mineral assets is evident experience gained during durin the world war emphasizes the advantage of an adequate supply of raw materials close at hand yet that there are certain economic limits to domestic independence in raw materials is clearly shown by the readjustments already made the more facts we possess bearing upon ubon the relative quantity and the relative availability of the mineral resources of our own and other countries the better able will be our captains of industry to decide whence they should derive their raw material the mines of the united states should be looked upon primarily as tributary to the many mills shops and factories in which the skilled labor of the country may find its opportunity port unity for a livelihood the output of raw minerals measures only the first step in industry more than a score of k geologists eol t oi have cooperated in the preparation of this atlas which was first undertaken during the world war as a part of the task of keeping american industries supplied with raw material and is to be regarded therefore as a by pro duct of the wartime war time activities of the geological survey the world atlas of commercial geolot geology y comprises 72 maps showing the mineral resources and production of the world by countries and 72 pages of descriptive text it can be purchased for 2 from the Di lector of the united states geological survey washington D C |
