It seems worth while for our associations of dog fanciers to undertake to develop varieties of dogs solely with reference to the intellectual qualities of the animal. I venture to suggest that those who seek this end should select some of the primitive types of form, such as are found among the undifferentiated mass of the species, those which are improperly termed mongrels, and this for the reason that among these unselected creatures the intelligence is quicker and more varied than it is in the highly developed varieties. Under skilful trainers the successive generations bred in the experimental station should be subjected to tests which will indicate the measure of intellectual ability. The results already attained by the unconscious selection which man has applied serve to indicate that at the end of a century, and perhaps in much less time, we might develop an animal which in various ways would come to a closer intellectual relation with man than any other lower species has attained. Cats deserve some mention for the reason, that, while they are the least essential, and on the whole the least interesting, of domesticated animals, they have had a certain place in civilization. They afford, moreover, a capital foil by which to set off the virtues of the dog. Nowhere else, indeed, among the creatures which are intimately associated with men, do we find two related forms which afford, along with a certain likeness, such great diversities of quality. We know nothing as to the time when the cat first found its way to the associations of man. Presumably this period was much later than the advent of the dog into the human family. The presumption rests upon the fact that while the dog does not demand fixed residence as a condition of its fealty, but is at home wherever his master is, the cat is the creature of the domicile, caring more indeed for its dwelling-place than it ever does for the inmates thereof. In a word, the creature must have come to us after our forefathers gave up the nomadic life. Nevertheless, the association is very ancient; it has endured in Egypt at least for a term of several thousand years. Among the curious features connected with the association of the cat with man, we may note that it is the only animal which has been tolerated, esteemed, and at times worshipped, without having a single distinctly valuable quality. It is, in a small way, serviceable in keeping down the excessive development of small rodents, which from the beginning have been the self-invited guests of man. As it is in a certain indifferent way sympathetic, and by its caresses appears to indicate affection, it has awakened a measure of sympathy which it hardly deserves. I have been unable to find any authentic instances which go to show the existence in cats of any real love for their masters.
