Show USEFUL. MINERALS OP THE UNITED STATES A new edition of the popular work entitled "Useful Minerals of the United States" is being published publish-ed by the United States Geological Survey, Department of the Interior, as Bulletin 624. It is a revised, enlarged and up-to-date edition of a bulletin that was issued about two years ago. A large edition of that edition was published but it soon became exhausted, and several thousand thou-sand applications tor it were received receiv-ed after the edition printed had been distributed. Bulletin 624 notes the enormous increase in development, production and value of the useful minerals of the country during the last 25 years and many of the changes and discoveries dis-coveries that have taken place in the mineral industry. It aims also to supply the rapidly growing demand de-mand for information regarding our mineral resources and the special demand de-mand occasioned by the European war. Besides giving several thousand new localities of mineral deposits and adding more than 160 new mineral min-eral names to the glossary, the new bulletin furnishes considerable additional ad-ditional information concerning certain cer-tain minerals, especially the uranium ura-nium and vanadium minerals found in the high plateau region of the west. The present bulletin like the earlier work, gives concisely, by the states and counties, the location of .the principal deposits of useful minerals mine-rals and includes a glossary showing the composition and character of each mineral and the location of its principal deposits. It gives also the principal uses of each mineral, which were not stated in the first edition. As a mineral directory it promises to be of service to scientific bureaus and educational institutions that prepare pre-pare replies to the numerous inquiries inqui-ries of the general public on subjects sub-jects that may be called commercial mineralogy, as well as to the prospector, pros-pector, miner, manufacturer, and the business man and student of economic econ-omic conditions. |
