DISCUSSION AND CORRESPONDENCE 



A SPLENDID SERVICE 



Apart from the eminent contribution 

 rendered to science and the Pan-Americaji 

 spirit by Dr. Branner in the publication of 

 his fine geological map and monograph,^ it is 

 a particularly distinguished and generous 

 service to common American interests made 

 by the Geological Society of America at the 



1 "Outlines of the Geology of Brazil; to accom- 

 pany tlie Geologic Map of Brazil," by John Cas- 

 par Branner, Bulletin Geological Society of Amer- 

 ica, Vol. 30, No. 2, June, 1919. 



expense of its own treasury. Eor the first 

 time the Geological Society has ventured so 

 far afield and freely invested its resources in 

 what might seem at passing glance purely the 

 scientific welfare of an alien country; but it 

 is not to be denied that the claim of fratern- 

 ity had no little to do with the attitude of the 

 Geological Society toward this enterprise. 

 The bond of geological brotherhood between 

 the United States and Brazil has been a long 

 and strong one. Out of the little village of 

 Aurora on Cajniga Lake, New York, came the 

 first impulse toward the establishment of this 

 tie, when the generosity of the late E. B. 

 Morgan enabled a Cornell professor and some 

 of his students in 1871 to begin the systematic 

 study of the rock geology of the Amazonas 



Thus started the Brazilian careers of Pro- 

 fessor Charles Fred Hartt and his young 

 associates, Orville A. Derby, Herbert H. 

 Smith and John C. Branner who joined the 

 work in 1874, and their labors are now a 

 historical part of the development of geology 

 on the South American continent. So per- 

 haps it is eminently appropriate that an 

 American Geological Society should now come 

 to the help of one of these pioneers in Brazil- 

 ian geology and enable him to summarize and 

 commemorate the results of his own and his 

 associates' life-long work in that coimtry. 

 Dr. Derby became a Brazilian subject; Dr. 

 Smith, after a life of rich experience as a 

 scientific collector, recently met a tragic end. 

 Upon Dr. Branner has fallen the mantle, for 

 during his active years he has been a frequent 

 visitor to Brazil and an unremitting student 

 of her geology. To him thus comes the 

 privilege of preparing the first geological map 

 of the whole area of that vast cotmtry so far 

 as exploration has gone, and of setting forth 

 the conclusions drawn by himself and by 

 many colleagues and collaborators in this 

 great field. 



This note is not intended to be a review or 

 critique of Dr. Branner's map. It is a most 

 illuminating production, of necessity drawn 

 on broad lines and with a few simple explana- 

 tory devices, thus intimating at a glance how 

 much remains for future students of the
