brutes the ganglia, lobes, or convolutions which house and direct such
powers; and no tribe of mankind has been found without them, however
undeveloped. Very limited, indeed, is the use of natural forces or of
supplied materials in the life of a brute. The birds pick up feathers,
hair, twigs; but no bird provides such things by deliberate prevision
and co-operation with nature. What animal sows that he may reap? The
so-called agricultural ants gather what they have not sown, and reap
what they have not planted. Man sows that he may gather; breeds that he
may use; and accomplishes civilization by an ever-increasing mastery and
adaptation of natural forces. An insect may float with the current on a
chip; but what one ever put a chip into the water? A beaver may build a
dam; but what beaver ever turned the heightened water on a wheel? The
dog may lie in a sunny spot; but what dog ever created artificial heat
or condensed by a lens the sun's heat on a particular point? The hen may
lay and incubate an egg; but what hen ever invented an incubator to
save her long sitting in one pose or place, or studied the development
of life in and from the egg she produced? The ox may select the richest
pasture; but never dreamed of creating a rich pasture by the culture and
fertilization of which he is the chief source. The tiger chooses and
slays his prey; but does not know how to propagate, develop, and safely
mature the animals on which he feeds. All animal life below man must
locate where its food abounds, or follow that food in its migrations or
seasonal changes. Man alone stores and transports his food, creating
commerce by his mastery of climate.
