shales and many large seams of coal, seemed so anomalous, that 
Sir William Logan naturally set aside as untenable the supposi- 
tion of contemporaneity with the Albion coal measures, tacitly 
classified the conglomerate beneath the latter, but coloured it on 
his map of the Pictou coal field as distinct from both the Coal 
Measures and the Millstone Grit. “ No rocks,” he says,! “ having 
the typical character of this conglomerate appear to have been 
brought to the surface by either the south or the east fault, or 
by Mr. Hartley’s west fault. This does not, however, disprove 
their possible presence beneath the whole of the productive area 
abutting against these faults and constituting the base of Dr. 
Dawson’s Middle Coal formation, as inferred by Mr. Hartley.” 
“This inference seems to be supported by the presence, 
immediately on the summit of the conglomerate, of the coal 
seam worked by Mr. William Fraser (Moose) for the burning of 
his limestone, and another said to overlie it; and although the 
occurrence of these is not strengthened by the known existence 
of any of the larger workable coal seams in the Pictou synclinal, 
the deposits of which have yet to be examined by the officers of 
the Survey, it would not be surprising to find, in a country 
apparently so broken by great dislocations, that the absence of 
the larger seams may be due to a structure resulting from some 
of these faults, of as important a character as those affecting 
the productive part of the field above New Glasgow.” 
Since 1869, however, the district referred to has been closely 
examined by the Geological Survey, shown to be broken bv no 
great dislocations, but on the contrary to be occupied by 
undisturbed strata which conformably overlie the conglomerate 
and are equivalent to those above the productive coal measures 
of the Joggins section. A glance at the geological map of this 
district will suffice to show that the conglomerate is the natural 
base of the Upper Carboniferous or Permian rocks of Merigomish, 
Pictou, River John and Waugh River. 
In support of Sir J. W. Dawson’s later views it has been 
stated that the fossils of the strata immediately overlying the
