The publication of an Official Geological Map, if not considered 

 final as regards the age and relation of the geological formations 

 included in its limits, is apt to be looked upon, especially by the 

 general public, as representing a consensus of opinion upon the part 

 of those concerned in its production, and is appealed to as though 

 the views embodied in it were not open to any further question. 



Such has been the case with the Geological Map of New Brunswick 

 which begun in 1880 and issued from time to time in successive sheets, 

 was completed in 1890. By most persons interested in the subject 

 it is still appealed to as giving the most reliable information with 

 regard to the large and very complicated region to which it refers. 

 But even during its preparation, as indicated by the accompanying 

 geological reports, the authors from time to time altered their views 

 as regards important questions involved, while there was far from an 

 entire agreement among the many investigators who took part in its 

 production, viz.: Bailey, Matthew, Ells, Mclnnes, Chas. Robb and 

 others. Moreover, since its completion, some of the debated points 

 of age or structure have acquired increased importance, while many 

 new questions have arisen requiring investigation and solution. In 

 fact at present there is hardly a group of rocks found in New Brunswick 

 about which it would not be easy to ask questions without the possi- 

 bility of a satisfactory answer. It is to the enunciation of some of these 

 problems and the question of their possible removal that it is the pur- 

 pose of this paper to refer. 



The formations will be considered in ascending order. 



Pre-Cambrian 

 The questions which arise in connection with the supposed Pre 

 Cambrian of New Brunswick are the following: —
