Even in death and decay it cannot set
free the sunbeams imprisoned in its tissue. The sun-force must stay,
shut up age after age, invisible, but strong; working at its own
prison-cells; transmuting them, or making them capable of being
transmuted by man, into the manifold products of coal--coke,
petroleum, mineral pitch, gases, coal-tar, benzole, delicate aniline
dyes, and what not, till its day of deliverance comes.
Man digs it, throws it on the fire, a black, dead-seeming lump. A
corner, an atom of it, warms till it reaches the igniting point; the
temperature at which it is able to combine with oxygen.
And then, like a dormant live thing, awaking after ages to the sense
of its own powers, its own needs, the whole lump is seized, atom
after atom, with an infectious hunger for that oxygen which it lost
centuries since in the bottom of the earth. It drinks the oxygen in
at every pore; and burns.
And so the spell of ages is broken. The sun-force bursts its prison-
cells, and blazes into the free atmosphere, as light and heat once
more; returning in a moment into the same forms in which it entered
the growing leaf a thousand centuries since.
Strange it all is, yet true. But of nature, as of the heart of man,
the old saying stands--that truth is stranger than fiction.
