COAL. [_Page 113._


1. Coal is dug out of the earth. Coal and iron are found together. But
coal is not a metal as iron is. It will not melt. We call it a mineral.

2. It is found in many parts of the world. There is a very large
quantity in our own country.

3. It is a black, shiny, opaque, and brittle mineral. Men have to go
deep down into the earth, into mines, to get it. They are in great
danger.

4. Coals were once forests, which sank lower and lower into the earth
hundreds and thousands of years ago. They became mixed with other
things, and in time were changed to coal. We can see the grain in some
of the coal, as we see it in wood.
