394 NORTHERN OUTCROP, CUMBERLAND COAL FIELDS—GILPIN. 
Brook to the St. George mine, a district about five miles in length. 
This end of the coal field will, from its proximity to the railway, 
and the regularity of the strata, prove an important future source 
of coal. 
These sections differ widely, and in addition to this there are 
numerous faults known on the River Herbert areas. A heavy fault 
is also reported on the west line of the Styles area. We thus find 
that the seams cannot with any show of reason be correlated 
with either of the coal-beds worked at the Joggins, so far as their 
sections are concerned, and the presence of heavy faults prevents 
a satisfactory comparison between those of areas separated by a 
short distance. 
Dr. Dawson considers the seams at the Victoria Colliery (al- 
ready referred to) as representing the New Mine seam, the coal 
bed (given in the section) lying eighteen feet above it, and ano- 
ther coal bed 35 feet below it, containing three feet of coal and 
shale as represented in the Joggins section. He also compares 
the Chignecto seam with the bed lying eighteen feet above the 
New Mine seam, and he further suggests that the equivalent of 
the main seam is yet to be found in the eastern part of the dis- 
trict. 
The work of the Geological survey has brought out new facts, 
which support his opinion as to the probable position of the 
Joggins main seam, while they oppose his correlation of the 
seams already given. 
On approaching the Styles mine from the north a band of fine 
grained conglomerate is met, composed largely of syenitic, quartz- 
ite, and slate pebbles, the whole having a greenish and red colour. 
The thickness of this conglomerate and some associated beds of 
red shale is about 1,500 feet, and it is underlaid by about 1,000 
feet of chocolate coloured shales and sandstones. 
This bed of conglomerate has been traced from a point several 
miles east of the Styles mine nearly to the Maccan River, and 
throughout this distance it preserves the same characteristics, and 
appears to form the summit of the Millstone Grit. There is also, 
as mentioned by Mr. McOuat, another point supporting this 
view, that is, the underlying chocolate coloured shales are seldom
