THE attention of Coal Owners, Coal Ex-

Collieries and their position with regard to
Railway Communication, Shipping Ports
and Canals.

These Maps will be found to be of incal-
culable value to all connected with the Coal
Trade, either as buyers or sellers; while
manufacturers of Mining Specialities and all
whose business takes them to Collieries will
appreciate their value as a time and money
saver.

different colours.
