Coal, The Fossil Fuel: Coal is found in the earth, sometimes near the surface and sometimes very deep down. Some of the best coal mines in England are half a mile under the earth. After being taken half a mile down the mine in a lift worked by machinery, the miners will have to walk about
another mile along the passages to the place where they have to work.


Coal is formed of the trees, leaves and gasses of old forests. The mass of vegetation in those old jungles gradually formed a layer, and in the course of centuries became buried under masses of earth. At first soft, it gradually became pressed down till it was hard and black. But the heat and light are absorbed from the sun are still in the coal and are given off when we burn it.


Coal is the finest fuel, giving a clear heat and burning for a long time. Most people in Europe still warm their houses by means of coal fires. What a lump of blessing coal is to dwellers in cold countries! It is also used in industry, for without coal we could not smelt the iron ore and produce iron and steel. Great industrial countries like Britain and America owe their prosperity to the fact that they have coal and iron mines close to each other.

In the best coal districts nowadays, the coal is cut and taken out by machinery.


Coal can be used as fuel directly or can be turned into gas. It gives bye-product of coke, tar or pitch, and a kind of petroleum at the same time. Again coal can be used for the generation of electricity. China is full of rich coal-fields which should yield good supplies in the future. In India, there are some districts where there is no coal, and that is why the poor people have to burn wood or the precious cow-dung which should be used to manure the fields. But it is probable that there are good supplies of coal in India which have not yet been worked, just as good as the West Bengal mines.
