UNDEVELOPED CUAL FIELDS OF NOVA SCOTIA—GILPIN. 1389 
In the section underlying the productive measures at Low 
Point, at a vertical distance of 600 feet below the top of the 
Millstone Grit, is the Mullins seam, 6 feet 4 inches thick. 
Several other smaller seams unknown in this section of which I 
have no details. 
On the North Sydney side of the harbor the Geological 
Survey give only one seam about 580 feet below the top of the 
Millstone Grit, the Matheson seam, 2 feet thick. It is claimed 
by those who have since prospected this district that there are 
several other seams up to 5 feet in thickness. 
On the Big Bras d’Or the sections of the Millstone Grit have 
hitherto shown only traces of coal. 
For a few years past attempts have been made to trace the 
Mullins seam southwardly into the extensive district lying 
between Sydney and Glace Bay, and to prove the Tracey seam 
northwardly into the same district. These etforts have not yet 
proved successful. There are a number of seams known in this 
area, as shown in the section, none, however, large enough to 
compete with those at present worked, although they will be 
drawn upon in the future when the larger seams become 
exhausted, and they contain in the aggregate many millions of 
tons of coal. 
On the Morrison road explorations have been carried on by 
Mr. Harold and other Sydney parties. They claim to have 
bored through a number of workable seams. The details of this 
exploration, not yet completed, will be received with interest, as 
if their claims as to the thickness of the seams are supported by 
a good quality of coal a most important addition will be made to 
the coal resources of the district. 
An interesting portion of this coal field was described by me 
in a paper read before you last winter, as the results of some of 
the prospecting for the Tracey seam. Attention was drawn to 
the curious fact that the fossils of the Cossitt coal field were 
identical with many characteristics of the true coal measures, 
although the locality lies in the heart of a wide expanse of 
Millstone Grit.
