KIRKUS REVIEW

This is the story of coal -- from its source, millions of years ago, to present day mining methods and modern uses of coal. The different kinds of coal, where it is found, why it burns; early mining in America; the prevention of mining accidents; products of coal -- among them the now famous sulfa drugs. Again simply written, excellent vocabulary, particularly useful in 3rd and 4th grades.
