COAL AND COAL-MINES.
COAL AND COAL-MINES.
There are few subjects of more importance, and few less known or thought about, than our coal-mines. Coal is one of our greatest blessings, and certainly one originating cause of England's greatness and wealth. It has given us a power over other nations, and vast sums of money are yearly brought to our country from abroad in exchange for the coal we send. Nearly £17,000,000 is the representative value of the coal raised every year at the pit's mouth, and £20,000,000 represent its mean value at t

THE STEAM-ENGINE.
THE STEAM-ENGINE.
The many varieties of the world's manufactures—one might almost call them wonders—are now so numerous, that to bring any particular one in a single form before this meeting is a matter of no easy nature. To-night, however, I have ventured to single out, and have the pleasure of bringing before you, the steam-engine, as the prime mover at present of our workshops and manufactories, as also the grand motive power of our railways, now so different from the time when the great Stephenson was said to
