Though by all geologists it has been conceded that the 

 New Glasgow Conglomerate at New Glasgow, is the base 

 of a continuous series of sediments whose upper portion is of 

 Permian age, yet there are two views advocated regarding 

 the age of the New Glasgow Conglomerate itself. By 

 Dawson and Hartley it has been contended that the con- 

 glomerate is of Millstone Grit or early Productive Coal 

 Measures age; this view was accepted by Logan. On the 

 other hand, Poole and Fletcher have argued that the con- 

 glomerate is of post- Productive Coal Measures age. Dawson 

 [6] based his view on two chief lines of evidence. 



(Firstly) A few miles west of New Glasgow there is 

 some appearance of an anticlinal fold in the conglomerate 

 suggesting that the strata are developed along a deformed 

 anticline and thus, countenance, the view that the strata 

 may underlie the Coal Measures lying not far east. 

 (Secondly) Dawson states that the fossils from the strata 

 immediately overlying the conglomerate, are similar to 

 those occurring in the Productive Coal Measures. Un- 

 fortunately, so far as known, no list of these fossils plant 

 and fish remains have ever been published. 



Pool [12] and Fletcher [7 and 8], contend that the New 

 Glasgow Conglomerate is of post-Productive Coal Measures 

 age because of two main reasons : — i^firstly) the conglomerate 

 uncomformably overlies the Millstone Grit and (secondly) 

 no strata similar to the New Glasgow Conglomerate have 

 been found beneath the Coal Measures in other parts of 

 the Pictou coal field or elsewhere in Nova Scotia. Other 

 lines of evidence support the general argument of Poole and 

 Fletcher and, in the absence of any detailed statement of 

 the palseontological evidence, appear to be quite conclusive. 



DETAILED DESCRIPTION. 



Logan has described the New Glasgow Conglomerate 

 in the following terms [11]. 



"At the bridge of New Glasgow is exposed a series of 

 conglomerates, which, in general colour, are between a 

 brick-red and chocolate or indian-red, and whose enclosed 

 masses, varying from the smallest pebbles to boulders of 

 two feet in diameter, are for the most part, unmistakably 

 derived from the red and greenish-grey sandstones, red 

 shales and impure nodular limestones of the rock last 

 described (Millstone Grit), some of them containing the
