Excerpt from A Coal Manual for Salesmen, Buyers and Users

Theophrastus, favorite pupil of Aristotle, in his book about stones, mentions earthy ones found in Liguria (modern Genoa) in Northern Italy, that kindled and burned like charcoal and were used by smiths. They were called Anthraces or charcoals, from their resemblance to the latter.

The beginnings of the modern coal trade, however, are found during the 13th century, when records of a more general utilization and of a regular trade in coals appear, but the modern use of coal may be said to have begun with the powerful impulse given to the iron industry about 1836, at the beginning of the Victorian era, mainly by the introduction of the hot blast as applied to iron furnaces.

Since that time the output of coal and the growing number of uses to which it or its derivatives are and have been put, have kept pace with population and civiliza tion, until now we not only get light, power and heat from coal but an ever increasing number of substances most necessary to our comfort and health, some of which had been obtained from natural sources, but many of which are new to us; beautiful dyes, delicate flavors, the fragrance of flowers, the most powerful drugs, material for modern explosives, antiseptics and disinfectants, roof ing material, road pavement and building material, oils of various kinds, fertilizers, besides many other substances, commercial uses for which have not yet been discovered.
