By GIFFORD PINCHOT
Governor of the Commonwealth of Pennsylvania

MECHANICAL energy is the heart of
modern civilization. It was the lack of
mechanical energy-power-that kept
men back so long in their struggle for
control over the elements. It was the
lack of it in large amounts which so long
delayed the coming of the degree of
safety and comfort which is now char-
acteristic of human life in America.
We owe the present American standard
of living mainly to our use of greater
quantities of power per inhabitant than
any other people on earth.
From the very earliest times until
about one hundred years ago the work
of the world was done either by human
muscle, by animal muscle, by the pres-
sure of the wind, or by the weight of
falling water. When the earliest Pha-
raohs ruled in Egypt, when Homer sang
of the siege of Troy, when the first
Christmas dawned to bless the earth,
when Columbus discovered a new con-
tinent, when William Penn taught
brotherhood in a new world, when
Franklin laid the foundation for modern
electrical development, when the Dec-
laration of Independence was signed,
men were still using the same four
sources of mechanical power, and had
never gone beyond them.
This limitation of available power
circumscribed human activity and held
back human progress to a degree we of
today find it difficult to understand.
I Governor Pinchot in his message to the Gen-
eral Assembly of the Commonwealth of Penn-
sylvania on February 17, 1925, presented so
effectively the possibilities of Giant Power and
the need for its guidance for the public use that
we reprint here, with his permission, part of that
message with slight modifications as the Intro-
duction to this volume.-THE EDITOR.

If the ancients of the old world and the
fathers of the new, hampered as they
were by the lack of power, still did great
things, they did them at a cost in time
and in sheer toil which we find it hard
even to imagine.
THE DISCOVERY OF STEAM
Upon a world so limited came the
discovery of the power of steam.
Steam altered the whole face of the
earth for its inhabitants. By the crea-
tion of a new industrial civilization it
utterly changed the conditions of hu-
man life. For the first time in history
goods could be produced in abundance
for all mankind. For the first time in
history this abundance could be carried
cheaply to all mankind. Steam forced
the replacement of individual effort and
home industry by industrial organiza-
tion, for the new steam engine was too
big, too expensive, and too complicated
to be used except by large numbers of
workmen under skilled supervision.
Out of steam grew the industrial order
and the material civilization of the
world today.
What the discovery of steam brought
with it was nothing less than a revolu-
tion. Because its revolutionary char-
acter was not foreseen and provided for,
the discovery of steam was followed by
generations of fighting on the part of
capital to keep, on the part of labor and
agriculture to secure, a share in the
rewards of greater production. That
struggle for economic independence and
equality of opportunity is far from set-
tled today. It has produced results of
enormous value to humanity, but at
enormous and unnecessary cost.
