– never the other one. There is no advantage in that, and no sense in it. All men do it, yet no man thought it out and adopted it of set purpose, I imagine. But it is a habit which is transmitted, no doubt, and will continue to be transmitted.

      Y.M. Can you prove that the habit exists?

      O.M. You can prove it, if you doubt. If you will take a man to a clothing-store and watch him try on a dozen pairs of trousers, you will see.

      Y.M. The cow illustration is not—

      O.M. Sufficient to show that a dumb animal's mental machine is just the same as a man's and its reasoning processes the same? I will illustrate further. If you should hand Mr. Edison a box which you caused to fly open by some concealed device he would infer a spring, and would hunt for it and find it. Now an uncle of mine had an old horse who used to get into the closed lot where the corn-crib was and dishonestly take the corn. I got the punishment myself, as it was supposed that I had heedlessly failed to insert the wooden pin which kept the gate closed. These persistent punishments fatigued me; they also caused me to infer the existence of a culprit, somewhere; so I hid myself and watched the gate. Presently the horse came and pulled the pin out with his teeth and went in. Nobody taught him that; he had observed – then thought it out for himself. His process did not differ from Edison's; he put this and that together and drew an inference – and the peg, too; but I made him sweat for it.

      Y.M. It has something of the seeming of thought about it. Still it is not very elaborate. Enlarge.

      O.M. Suppose Mr. Edison has been enjoying some one's hospitalities. He comes again by and by, and the house is vacant. He infers that his host has moved. A while afterward, in another town, he sees the man enter a house; he infers that that is the new home, and follows to inquire. Here, now, is the experience of a gull, as related by a naturalist. The scene is a Scotch fishing village where the gulls were kindly treated. This particular gull visited a cottage; was fed; came next day and was fed again; came into the house, next time, and ate with the family; kept on doing this almost daily, thereafter. But, once the gull was away on a journey for a few days, and when it returned the house was vacant. Its friends had removed to a village three miles distant. Several months later it saw the head of the family on the street there, followed him home, entered the house without excuse or apology, and became a daily guest again. Gulls do not rank high mentally, but this one had memory and the reasoning faculty, you see, and applied them Edisonially.

      Y.M. Yet it was not an Edison and couldn't be developed into one.

      O.M. Perhaps not. Could you?

      Y.M. That is neither here nor there. Go on.

      O.M. If Edison were in trouble and a stranger helped him out of it and next day he got into the same difficulty again, he would infer the wise thing to do in case he knew the stranger's address. Here is a case of a bird and a stranger as related by a naturalist. An Englishman saw a bird flying around about his dog's head, down in the grounds, and uttering cries of distress. He went there to see about it. The dog had a young bird in his mouth – unhurt. The gentleman rescued it and put it on a bush and brought the dog away. Early the next morning the mother bird came for the gentleman, who was sitting on his veranda, and by its maneuvers persuaded him to follow it to a distant part of the grounds – flying a little way in front of him and waiting for him to catch up, and so on; and keeping to the winding path, too, instead of flying the near way across lots. The distance covered was four hundred yards. The same dog was the culprit; he had the young bird again, and once more he had to give it up. Now the mother bird had reasoned it all out: since the stranger had helped her once, she inferred that he would do it again; she knew where to find him, and she went upon her errand with confidence. Her mental processes were what Edison's would have been. She put this and that together – and that is all that thought IS – and out of them built her logical arrangement of inferences. Edison couldn't have done it any better himself.

      Y.M. Do you believe that many of the dumb animals can think?

      O.M. Yes – the elephant, the monkey, the horse, the dog, the parrot, the macaw, the mocking-bird, and many others. The elephant whose mate fell into a pit, and who dumped dirt and rubbish into the pit till bottom was raised high enough to enable the captive to step out, was equipped with the reasoning quality. I conceive that all animals that can learn things through teaching and drilling have to know how to observe, and put this and that together and draw an inference – the process of thinking. Could you teach an idiot of manuals of arms, and to advance, retreat, and go through complex field maneuvers at the word of command?

      Y.M. Not if he were a thorough idiot.

      O.M. Well, canary-birds can learn all that; dogs and elephants learn all sorts of wonderful things. They must surely be able to notice, and to put things together, and say to themselves, "I get the idea, now: when I do so and so, as per order, I am praised and fed; when I do differently I am punished." Fleas can be taught nearly anything that a Congressman can.

      Y.M. Granting, then, that dumb animals are able to think upon a low plane, is there any that can think upon a high one? Is there one that is well up toward man?

      O.M. Yes. As a thinker and planner the ant is the equal of any savage race of men; as a self-educated specialist in several arts she is the superior of any savage race of men; and in one or two high mental qualities she is above the reach of any man, savage or civilized!

      Y.M. Oh, come! you are abolishing the intellectual frontier which separates man and beast.

      O.M. I beg your pardon. One cannot abolish what does not exist.

      Y.M. You are not in earnest, I hope. You cannot mean to seriously say there is no such frontier.

      O.M. I do say it seriously. The instances of the horse, the gull, the mother bird, and the elephant show that those creatures put their this's and thats together just as Edison would have done it and drew the same inferences that he would have drawn. Their mental machinery was just like his, also its manner of working. Their equipment was as inferior to the Strasburg clock, but that is the only difference – there is no frontier.

      Y.M. It looks exasperatingly true; and is distinctly offensive. It elevates the dumb beasts to – to—

      O.M. Let us drop that lying phrase, and call them the Unrevealed Creatures; so far as we can know, there is no such thing as a dumb beast.

      Y.M. On what grounds do you make that assertion?

      O.M. On quite simple ones. "Dumb" beast suggests an animal that has no thought-machinery, no understanding, no speech, no way of communicating what is in its mind. We know that a hen HAS speech. We cannot understand everything she says, but we easily learn two or three of her phrases. We know when she is saying, "I have laid an egg"; we know when she is saying to the chicks, "Run here, dears, I've found a worm"; we know what she is saying when she voices a warning: "Quick! hurry! gather yourselves under mamma, there's a hawk coming!" We understand the cat when she stretches herself out, purring with affection and contentment and lifts up a soft voice and says, "Come, kitties, supper's ready"; we understand her when she goes mourning about and says, "Where can they be? They are lost. Won't you help me hunt for them?" and we understand the disreputable Tom when he challenges at midnight from his shed, "You come over here, you product of immoral commerce, and I'll make your fur fly!" We understand a few of a dog's phrases and we learn to understand a few of the remarks and gestures of any bird or other animal that we domesticate and observe. The clearness and exactness of the few of the hen's speeches which we understand is argument that she can communicate to her kind a hundred things which we cannot comprehend – in a word, that she can converse. And this argument is also applicable in the case of others of the great army of the Unrevealed. It is just like man's vanity and impertinence to call an animal dumb because it is dumb to his dull perceptions. Now as to the ant—

      Y.M. Yes, go back to the ant, the creature that – as you seem to think – sweeps away the last vestige of an intellectual frontier between man and the Unrevealed.

      O.M. That is what she surely does. In all his history the aboriginal Australian never thought out a house for himself and built it. The ant is an amazing architect. She is a wee little creature, but she builds a strong and enduring house eight feet high – a house which is as large in proportion to her size as is the largest capitol or cathedral
