The following analyses made at different periods will show the 
general uniformity of the seam :

Of the underlying seams in the North Sydney district, not 
much can yet be said. The General Mining Association has 
recently proved them by a shaft to the fourth seam. These 
seams are of good quality, and from three to four feet thick. I 
append an analysis of the third seam, made a few years ago, 
from samples taken from the openings of the North Sydney 
Mining Company, along its outcrop :—

These seams are now receiving attention at the hands of the 
Sydney Coal Company, and, although thinner than the main 
seam, will undoubtedly in the near future prove valuable from 
their uniformity and proximity to deep water.
