This much is certain, and is denied by no competent investigator: whatever has been in your mind is there still, and it is possible to find a way of tapping the buried memory. An old woman, delirious with fever, begins to babble in a strange language, and it is discovered that she is talking ancient Hebrew. The woman is entirely illiterate, and her conscious memory knows no language but her own, her conscious mind has no ideas beyond those of her domestic life and the gossip of the village. But investigation is made, and it is discovered that when this woman was a girl, she worked in the home of a Hebrew scholar, and heard him reading aloud. She did not understand a word of what she heard, and was not consciously listening to it; nevertheless, every syllable of it had been stored away forever by her subconscious mind. Innumerable cases of this sort have been established; and, as a matter of fact, we might have been prepared for such discoveries by the memory-feats of the conscious mind. It is well known that Mozart, when a child, could listen to a new opera, and go home and play it over note for note. At present there is a child in America, giving exhibitions in public, carrying on thirty games of chess at the same time. There have been others who do sums of mental arithmetic, such as multiplying thirty-two figures by thirty-two figures, or reciting the Bible backwards. All this seems incredible; and yet there is something still more incredible. Suppose that these same powers, which are stored in our subconscious minds, were stored also in the minds of animals! A few years ago Maurice Maeterlinck published a book, "The Unknown Guest," in the course of which he tells about his experiments with the so-called Elberfeld horses: two animals which had been trained for years by their owner to give signals by moving their forefeet, and which apparently could count and divide and multiply large sums, and extract square and cube root, and spell out names, and recognize sounds, scents and colors, and read time from the face of a watch. Of course, it is easy to say that this is absurd, that the horses must have got some signals from their trainer; but, as it happened, they would do their work in the absence of their trainer; they would do it in the dark, or with a sack over their heads, and the best scientific minds of Germany were unable to suggest any test conditions which could not be met. There have been many gigantic frauds in the world, and this may have been one of them; on the other hand, there have been many new discoveries, and for my part I will finish exploring the miracles of the subconscious mind of man, before I presume to say that anything is impossible in the subconscious mind of a horse or a dog. Also I will wait for some learned person to explain to me how the subconscious minds of horses and dogs know enough to build and repair their bones and teeth, so cleverly that modern
