THE LOCOMOTIVE. -153<br />

degree of engineering instinct and technical skill, yet it occurred in an antiquity so<br />

remote that we shall never be able to do honor to the first great hydraulic engineer, the<br />

inventor of the water-wheel. With the introduction of water power began, although<br />

at first in a very small way, the use of machinery as a substitute for manual skill. As<br />

long as the workman furnished all of the power demanded by his handicraft, the ma-<br />

chinery he employed was limited, often to his own fingers and hands, supplemented by<br />

a few tools of the simplest kind.<br />

Curiously, the word "manufacturing" literally means " making by hand," which<br />

is just what it does not mean in its modern acceptation, and in this modern sense manufacturing,—<br />

" making things by machinery," — practically began with the introduc-<br />

tion of water power, by which machinery could be run. Instead of pounding the corn<br />

or turning the millstone, men occupied themselves with the far more agreeable task of<br />

seeing that the mill was supplied with material; instead of making the wheels go<br />

round, they watched them go, and saw that they went properly. This was the first<br />

great step towards emancipation from the slavery of that unintelligent toil in which<br />

man differs from the beasts of the field only by being inferior to them.<br />

Up to the beginning of the nineteenth century no other sources of power than these<br />

three,— muscle, air in motion, and water.— were extensively employed. <strong>The</strong> only<br />

opportunity for great expansion in the world's output of work was in the greater use of<br />

water and wind. But while the total energy embodied in these two elements was enor-<br />

mous, its utilization was subject to such serious limitations as to time, place, rate of<br />

supply, and others, that power development was slow, coming, when it came at all, as a<br />

result, and not as a cause, of the steady enlargement of human enterprise. Wind<br />

power was used only as a last, resort where nothing else was available. Water power<br />

could be used only where it existed, and for this reason it sometimes directed the<br />

course of exploration and colonization ; but agricultural resources and possibilities<br />

were always considered as vastly more important. For these reasons those arts and<br />

industries dependent upon the use of machinery or upon rapidity or cheapness of trans-<br />

portation made comparatively little progress during several centuries preceding the<br />

nineteenth, being, in the nature and quality of their products, not very different from<br />

what they were at the beginning of the sixteenth, and, indeed, a thousand years had<br />

brought no remarkable extension in their operations nor innovation in their methods.<br />

<strong>The</strong> g'reat revolution in industrial processes and operations which constitutes the<br />

glory of the nineteenth century began with the recognition of the value of heat energy<br />

and the possibility of transforming it into useful forms of power. More than a thou-<br />

sand years ago this transformation was attempted, with little real success, however, and<br />

with less understanding of the nature and meaning of the operation. It was only when<br />

this was revealed by the genius of Watt and Rumford that the new era actually set in.<br />

<strong>The</strong>y, first of all, distinctly comprehended the interrelation of heat and mechanical<br />

energy,— their equivalence and capacity for transformation. <strong>The</strong>y showed that any<br />

source of heat was a source of power, and the combustion of fuel began at once tq super-<br />

sede or supplement the use of muscle, water, or wind in the work of the world. .<br />

<strong>The</strong> new power possessed so many advantages over the old, especially in availabil-<br />

ity and constancy, that its development was rapid, even in the beginning. <strong>The</strong> limita-<br />

tions to the current supply of combustible material in the form of wood would soon<br />

have checked this development, but, happily, an enormous, apparently inexhaustible<br />

stock of fuel in the convenient form of coal was at hand, and with continued improvement<br />

in the construction and efficiency of the engine by means of which the transfor-<br />

mation of heat into power is accomplished, the combustion of fuel and the transmuta-
