356 HONEYMAN ON NOVA SCOTIAN GEOLOGY. 



rill marlcs, casts of ferns and reptilian foot prints in abundance. 

 These foot prints are of varying shapes and sizes, some of them are 

 truly formidable. Some of the reptiles had walked over the rain- 

 pitted mud in a soft state and left deep impressions ; others had 

 walked over it when less soft and left impressions less deep ; others 

 had traversed the mud when it was netted with shrinkage cracks 

 and left faint impressions. One had set his foot on a fern leaf 

 which lay in his path, another between two long series of right and 

 left steps has left a continuous tail-trail. These are to be found in 

 the Museum. 



It was fortunate that the Intercolonial Railway took its present 

 course after passing Smith's Brook. To the right, at the distance 

 of half a mile, we find at a bridge of Wallace Eiver, that the 

 lower carboniferous conglomerate lies directly on the continuation 

 of the rocks of Smith's Cutting, so that in this direction the con- 

 glomerate, diorites, fossiliferous shales, &c. have all been denuded 

 by the lower carboniferous seas, and covered by their shingle 

 (conglomerates.) 



To the (left) west, at a distance of three miles, we find that the 

 work of destruction has been more complete, as the lower carbon- 

 iferous conglomerate lies directly on the syenite. The interesting 

 pre-carboniferous rocks of the northern part of the Intercolonial 

 Railway in the Cobequids, is only a remnant left to show what once 

 existed, and to reveal facts in geological history altogether at 

 variance with our hitherto received opinions of the geological 

 structure of the Cobequid Mountains. 



In my examination of this and other sections of the Cobequid 

 Mountains, I was accompanied by Mr. Andrew Jack, and occasion- 

 ally by Mr. Frank West and Mr. Robie Cogswell. These gentle- 

 men added many interesting fossils to our Went worth collection. 



I am very much indebted to Jp. ^, Archibald, Esq., C. E., for 

 the use of the Intercolonial Railway working plants and sections, 

 by which I am enabled to give accurate measurements of the 

 various groups of rocks and sections.
