The analysis of the Black seam made in the year 1878 has a 
complete sample column of coal representing the whole seam as 
then worked. A companion column was presented to the 
museum of the Geolegical Survey at Ottawa. The section of the 
seam was as follows :—

I need not repeat here the minute description given then of 
the various layers. It may be stated that the coal of the sample 
was bright, with occasional cale-spar and pyrites films, with 
somewhat irregular fracture. In the vicinity of the point in the 
mine where the sample was taken a large amount of coal was 
beautifully iridescent, recalling that splendid mineral Chry- 
socolla. Samples of this when analysed with the means at my 
disposal did not give a reason for the coloring. It may have 
been due to some process of oxidation of iron pyrites.
