SCENE IN A COAL MINE
But the world must have coal, for, used for our great boilers, it drives our powerful locomotives, sends mighty vessels plowing across the ocean, and supplies the power which turns the wheels of industry, both great and small. Yes, the world must have coal. So Uncle Sam, in pity for the miners who brave these awful dangers, has bought a mine at Bruceton, a short distance from Pittsburgh. There the government is making experiments to find out the causes of explosion, aiming in this way to protect the miners by lessening their dangers.

Thousands of these ovens are located in the Pittsburgh district, and their fires at night illuminate the country for miles. The coke is used as fuel in the steel furnaces of Pittsburgh, Cleveland, Chicago, and other cities.
