COAL,.
The coal trade in India is daily beeoming of greater
imnortance. The amount raised had mcreased be-
tween the years 1858 and 1868 from 220,082 tons to
484 642 tons, or considerably more than doublecl.
The mines are gradually being extended and worked
in a better manner tban formerly, and the coal is
sent to market in a better state. The series of
specimens exhibited contains examples of almost
every variety of coal now in use.
