The coal field is remarkably free from disturbances, etc., and 
Professor Lesley, in a report, dwells strongly on this point. 
Nearly all the seams lie at easy angles, yield little water, and 
owing to the generally firm character of the roof, they can be 
mined with unusual cheapness and safety. So strongly marked 
is the impermeable nature of the strata, that at a moderate depth 
the submarine workings are perfectly dry. 
Shales, arenaceous and argillaceous, with red and green marls, 
make up about one-half the total thickness of this section. The 
shales pass into sandstenes and frequently carry ironstone
