The limitations of the domesticating work, the fact that as between two kindred species the one has been chosen by man and the other left, indicate the truth--which is generally of much importance--that the intellectual qualities of animals commonly differ more than their frames. This is a part of the larger fact that with the advance in organization the individuality, as regards the whole spiritual field in persons and species alike, becomes greater. The culmination of the tendency is seen in man, where, with bodies which do not vary much, we have an almost infinite range in individual qualities. This is perhaps a good place in which to make answer to the suggestion that the domesticability of the animal species is in inverse proportion to their native courage and independence of mind. The reader will see how fallacious is this common notion if he will consider the quality of the supremely domesticated creature, the dog. There is probably no beast which has a larger share of natural courage and of independent motive. When not under the control of their masters, they have perhaps as free a contact with nature as any creature in the world; the same thing may be said of the elephant, which, next to the dog, lends himself most obediently to the requirements of the master. Owing to the power of his huge body and to the ease with which he wins his food, he is in his native wilds the least dependent of land animals. Except from the assaults of man, he has nothing to fear; yet when enslaved he at once surrenders himself to his captors. In general, it may be said that the true gauge of domesticability is the sympathetic motive, that strange outgoing spirit which leads the mind to recognize the life about it and to accept that life as a part of its own. In other words, the domesticability of man is due to his willingness to enter into social relations and rests on the same foundation that supports his intercourse with the lower animals he has won to his use.
