REPORT OF THE SPECIAL COMMITTEE FOR THE 

 LAKE SUPERIOR REGION 



TO C. WILLARD HAYES, ROBERT BELL, FRANK D. ADAMS, AND CHARLES 

 R. VAN HISE, GENERAL COMMITTEE ON THE RELATIONS OF THE 

 CANADIAN AND THE UNITED STATES GEOLOGICAL SURVEYS 



INTRODUCTORY NOTE BY C. R. VAN HISE 



The report below of the special committee on the nomenclature 

 and correlation of the geological formations of the United States 

 and Canada is the first joint report of the geologists of the two coun- 

 tries. Before the death of Dr. G. M. Dawson, formerly director 

 of the Canadian Geological Survey, I had correspondence with him 

 in reference to joint field-work in the Lake Superior region. It was 

 agreed between us that such field-work should be undertaken, but 

 his untimely death occurred before anything was done. 



After Dr. Dawson's death I continued correspondence upon the 

 subject with Dr. Robert Bell, acting director of the Canadian Geo- 

 logical Survey. As a result of this correspondence, December 22, 

 1902, Dr. Bell wrote to Dr. C. D. Walcott, director of the United 

 States Geological Survey, suggesting a conference in reference to 

 the mutual interest of the two Surveys. This letter led to the appoint- 

 ment of a committee — consisting of C. W. Hayes and C. R. Van 

 Hise, for the United States Geological Survey, and Robert Bell and 

 Frank D. Adams, for the Canadian Geological Survey — to consider 

 all questions as to the successions of formations, and as to nomen- 

 clature, which concerned the two Surveys.
