THE FUTURE OF MINERALOGY IN 

 AMERICAi 



INTRODUCTION 



This meeting is the culmination of repeated 

 efforts extending oyer a period of more than 

 one hundi-ed years to band the mineralogists 

 of America together and to maintain a 

 journal devoted primarily to mineralogy and 

 cognate sciences. Although our colleagues in 

 England and France organized over forty 

 years ago, in 1876 and 1878, respectively, we 

 were unable to do so until a year ago. The 

 past year has been primarily one of adjust- 

 ment and development and of bringing the 

 need of such an organization more strongly 

 to the attention of those interested. It has 

 also been a period during which our ideas of 

 what the society should be have become some- 

 what clarified. The progress made has been 

 most gratifying. We are now a going con- 

 cern with some very tangible assets, and there 

 are already strong assurances of a most in- 

 fluential future. As retiring president, I 

 desire to discuss briefly some of the important 

 phases in the development of mineralogy in 

 America, and the various efforts made to 

 organize a national society, and to found a 

 journal; also to interpret, if possible, the 

 function of mineralogy in our present-day 

 educational and scientific programs and to 

 indicate some probable lines of future devel- 

 opment. 



THE PERIOD OF EARLY DEVELOPMENT, 1785-1860 



The earliest published papers dealing with 

 the mineralogy of America were apparently 

 those which appeared in the Memoirs of the 

 American Academy of Arts and Sciences, in 

 1785. These were followed two years later by

 eralogical Society of America, Chicago, December 

 29, 1920.
