508 THE DEVONIAN PERIOD. 



on its northern also, where, however, it is succeeded, at a very- 

 short distance, by beds of the Lower Coldbrook. Owing to the 

 disturbances and foldings alluded to in the description of the latter, 

 the whole vast mass of the Lower and Upper Bloomsbury, St 

 John slates, and Dadoxylon sandstones, have mostly disappeared, 

 and we here find beds even below the base of the Silurian almost 

 side by side with the shales of the Upper Devonian. 



" From Vaughan's Brook, in the neighbourhood of Quaco, the 

 upper member of the group now under consideration begins rapidly 

 to widen, and to the eastward soon attains an enormous development. 

 Higher members than those last described appear at Melvin's Beach ; 

 and thence, with the exception of a few isolated Carboniferous 

 deposits at Salmon River, Goose Creek, and Martin's Head, extend 

 with a bold and unbroken front along the coast to Point Wolf, at 

 the western limit of Albert County. They thence no longer keep 

 the shore, but, pursuing their normal course, may be traced in a 

 series of bold high ridges as far as Shepody Mountain. 



" While the southern limit of the group is thus uniform and regu- 

 lar, the line which marks its northern boundary is more difficult of 

 recognition. Owing to one or more immense synclinal folds, the 

 area covered by these rocks is enormously increased, and from the 

 limited space occupied near the sea coast, behind Quaco, now widens 

 until it embraces the whole extent of country south of the Shepody 

 Road. On the latter thoroughfare the rocks of the group were 

 first observed near Wallace's Post Office, in the parish of Hammond, 

 King's, and near the source of the Great and Little Salmon Rivers. 

 On the last named stream they were found to occupy the whole 

 country southward to the coast. Whether they similarly occupy the 

 entire valley of the former has not been ascertained : the difficulties 

 of descending these rapid and mountainous water-courses, through 

 a country without a settlement, being of too serious a character 

 to admit of exploring both of the above named streams. The limits 

 of the group in this direction, however, cannot vary far from the 

 outlines as laid down on the Map. 



" Following the line of the Shepody Road from the point 

 above mentioned, the rocks of the present group, or ' coast series ' 

 as it may conveniently be termed, have been distinctly traced to the 

 eastward as far as the high lands back of Hopewell, while deposits, 

 probably referable to the same series, have been observed at a great 

 variety of places both in the county of King's and eastward in that 

 of Albert." These will be found severally referred to in the remarks 

 on the characters of the group in Professor Bailey's Report.
