t may be more simply explained. How could the mare have known her companion was blind? What could any horse know about such a disability? The only thing implied in the incident is the attachment of one animal for another. The mare heard her mate calling, probably in tones of excitement or distress, and she flew back to her. Finding her all right, she turned toward the salt again and was followed by her fellow. Instinct did it all. My own observation of the wild creatures has revealed nothing so near to human thought and reflection as is seen in the cases of the collie and pointer dogs above referred to. The nearest to them of anything I can now recall is an incident related by an English writer, Mr. Kearton. In one of his books, Mr. Kearton relates how he has frequently fooled sitting birds with wooden eggs. He put his counterfeits, painted and marked like the originals, into the nests of the song thrush, the blackbird, and the grasshopper warbler, and in no case was the imposition detected. In the warbler's nest he placed dummy eggs twice the size of her own, and the bird proceeded to brood them without the slightest sign of suspicion that they were not of her own laying. But when Mr. Kearton tried his counterfeits upon a ring plover, the fraud was detected. The plover hammered the shams with her bill "in the most skeptical fashion," and refused to sit down upon them. When two of the bird's own eggs were returned to the nest and left there with two wooden ones, the plover tried to throw out the shams, but failing to do this, "reluctantly sat down and covered good and bad alike." Now, can the action of the plover in this case be explained on the theory of instinct alone? The bird could hardly have had such an experience before. It was offered a counterfeit, and it behaved much as you or I would have done under like conditions, although we have the general idea of counterfeits, which the plover could not have had. Of course, everything that pertains to the nest and eggs of a bird is very vital to it. The bird is wise about these things from instinct. Yet the other birds were easily fooled. We do not know how nearly perfect Mr. Kearton's imitation eggs were, but evidently there was some defect in them which arrested the bird's attention. If the incident does not show powers of reflection in the bird, it certainly shows keen powers of perception; and that birds, and indeed all animals, show varying degrees of this p
