360 TRIASSIC(P) ROCKS OF DIGBY BASIN. BAILEY. 



perpendicularly, making a very marked appearance in the 

 face of the cliff, and having much of the aspect of a dyke. It 

 is, however, wholly made up of detached blocks, some of 

 them two or three feet long, of the same nature, and some of 

 them exhibiting the prismatic shape of the trap columns near 

 by. In some instances, however, they are rounded. No trace 

 of the ordinary red sandstones or of any beds resembling those 

 about Digby is to be seen. 



It seems hardly possible that the material of this agglomerate 

 should have received its present position except through intro- 

 duction from above into a previously opened fissure ; but whether 

 introduced contemporaneously with the lava flows and ash 

 accumulations represented in the neighboring dolerites and 

 amygdaloids, i. e., in the Trias-Jura epoch, or later and possibly 

 in the Quaternary, is a question which the writer is at present 

 unable to answer. 



Reviewing the entire subject, it is evident that there are still 

 some unsolved problems in connection with the supposed Mesozoic 

 rocks of the Bay of Fundy trough (including in the latter the 

 Annapolis Basin) ; and if the observations here given prove the 

 means of originating any further enquiries in this direction, the 

 purpose of this paper will have been served.
