The first seam met is one on the west side of the River, and 
it is stated to measure about 2 ft. 6 in. of coal. The nine feet 
seam, so-called, had not been opened at the time of my visit, 
and the thickness is that given by the man in charge of the 
boring. The seam below this is exposed on the west bank of the 
river, nearly on the line of the seam just referred to as being 
nine feet thick. 
The six feet seam was opened last winter by a short slope, and 
about 50 tons-of coal were extracted. It is stated to have in the 
centre a band of shaley coal about 9 inches thick. I was unable 
to verify the dimensions by actual measurement, as all the 
openings were full of water at the time of my visit, but the 
outcrop of the bed under the waters of the river apparently 
confirmed them. 
The coal leoked unusually well for a crop exposure, and 
samples selected to form an average gave the following results :— 
Coal compact. Cleavage planes very obliquely inclined to 
each other. Fractures of the coal presented a conchoidal and 
lustrous appearance. The deposition planes showed a good deal 
‘of mineral charcoal. The coal is laminated with numerous 
bright pitchy layers up to one-half of an inch in thickness. A 
few films of calc-spar showed in the cleavage planes, and there 
was very little visible pyrites. Powder dark reddish brown.
