COAL. 
The following statement of the Coal raised since the year 1829 
shows the progress made in this bniiich of mining. Large tracts 
of coal land have been taken np with a view to open new 
collieries, and there is every reason to believe that ere long the 
quantity of coal raised in this Colony will far exceed the quantity 
being raised at present. The extent and value of our coal beds 
are so great tliat the supply may be said to be practically 
inexhaustible, and the demand, both for home consumption and 
for export, is likely to increase to such an extent as to be 
limited only by the raising power of our collieries and the 
facilities for bringing the coal to market.
