THE STORY OF A PIECE OF COAL
WHAT IT IS, WHENCE IT COMES, AND WHITHER IT GOES
BY EDWARD A. MARTIN, F.G.S.
1896
PREFACE.
The knowledge of the marvels which a piece of coal possesses within
itself, and which in obedience to processes of man's invention it is
always willing to exhibit to an observant enquirer, is not so widespread,
perhaps, as it should be, and the aim of this little book, this record of
one page of geological history, has been to bring together the principal
facts and wonders connected with it into the focus of a few pages,
where, side by side, would be found the record of its vegetable and
mineral history, its discovery and early use, its bearings on the great
fog-problem, its useful illuminating gas and oils, the question of the
possible exhaustion of British supplies, and other important and
interesting bearings of coal or its products.
In the whole realm of natural history, in the widest sense of the term,
there is nothing which could be cited which has so benefited, so
interested, I might almost say, so excited mankind, as have the
wonderful discoveries of the various products distilled from gas-tar,
itself a distillate of coal.
Coal touches the interests of the botanist, the geologist, and the
physicist; the chemist, the sanitarian, and the merchant.
In the little work now before the reader I have endeavoured to recount,
without going into unnecessary detail, the wonderful story of a piece of
coal.

CHAPTER I
.
THE ORIGIN OF COAL AND THE PLANTS OF WHICH IT IS
COMPOSED.
From the homely scuttle of coal at the side of the hearth to the
gorgeously verdant vegetation of a forest of mammoth trees, might
have appeared a somewhat far cry in the eyes of those who lived some
fifty years ago. But there are few now who do not know what was the
origin of the coal which they use so freely, and which in obedience to
their demand has been brought up more than a thousand feet from the
bowels of the earth; and, although familiarity has in a sense bred
contempt for that which a few shillings will always purchase, in all
probability a stray thought does occasionally cross one's mind, giving
birth to feelings of a more or less thankful nature that such a store of
heat and light was long ago laid up in this earth of ours for our use,
when as yet man was not destined to put in an appearance
