than it follows, that, because they can dwarf a tree, or
alter its aspect by stunting its growth in one direction and forcing it
in another, therefore the earth, or the physical conditions connected
with their growth, can create a Pine, an Oak, a Birch, or a Maple.
I confess that in all the arguments derived from the phenomena of
domestication, to prove that all animals owe their origin and diversity
to the natural action of the conditions under which they live, the
conclusion does not seem to me to follow logically from the premises.
And the fact that the domesticated animals of all races of men, equally
with the white race, vary among themselves in the same way and differ
in the same way from the wild Species, makes it still more evident that
domesticated varieties do not explain the origin of Species, except, as
I have said, by showing that the intelligent will of man can produce
effects which physical causes have never been known to produce, and that
we must therefore look to some cause outside of Nature, corresponding in
kind, though so different in degree, to the intelligence of man, for
all the phenomena connected with the existence of animals in their wild
state. So far from attributing these original differences among animals
to natural influences, it would seem, that, while a certain freedom of
development is left, within the limits of which man can exercise his
intelligence and his ingenuity, not even this superficial influence is
allowed to physical conditions unaided by some guiding power, since in
their normal state the wild Species remain, so far as we have been able
to discover, entirely unchanged,--maintained, it is true, in their
integrity by the circumstances that were established for their support
by the power that created both, but never altered by them. Nature holds
inviolable the stamp that God has set upon his creatures; and if man
is able to influence their organization in some slight degree, it is
because the Creator has given to his relations with the animals he has
intended for his companions the same plasticity which he has allowed to
every other side of his life, in virtue of which he may in some sort
mould and shape it to his own ends, and be held responsible also for its
results.

The common sense of a civilized community has already pointed out the
true distinction in applying another word to the discrimination of the
different kinds of domesticated animals. They are called Breeds, and
