The time has come when a horse may be as useful as a university.
At Yale University, one day, I heard a professor of science tell those boys that a horse has within its body so much galvanic or electric force continually generated by the activities of life, that if that electricity could be concentrated and held to a certain point, a horse could stand still and run a forty-horse power electric engine. He went further than that and said that a man has within his living body sufficient continually generated electricity which, if it were brought to a point, might enable him to stand still and run a ten-horsepower electric engine. I went out of that class-room with a sense of triumph, thinking:
"There is going to be use, after all, for the loafers who stand on the corners and smoke!"
In Europe, some years ago, a sewing-machine was invented on which a lady put her bare feet, and her electric forces started the machine. This power does not yet run the machine strong enough to force the needle for real sewing. The only question is to get more of the electricity of that lady through the machine and secure the greater power. Then if a young man wants a valuable wife he must marry one "full of lightning."
The time is very near at hand when all the motive power of the world may be furnished by animal life. When they get one step further the greatest airships will go up and take with them a lap dog. The airship will require no coal, no oil, but just the electric force of that lap dog; and if they carry up enough to feed that dog he will furnish the power to run the motors. The great high seas of the air will be filled with machines run by lap dogs or the electricity of the aviator himself. It is not so far away as many of you may suppose, and it is the greatly needed improvement of this time, not so much for the purpose of the war, as for peace.
The time has come when an old hen may become a great instructor of the world. I would rather send my child to an old hen than to any professor I ever saw in my life. That old biddy which scratches around your door, or who cackles beside your fence, or picks off your flowers, knows more of some things than any scientific professor on the face of the earth. I wish I knew what that old hen does. But there are some professors who pretend to have a wonderful intellect, who say:
"I graduated from Leipsic or from Oxford or Harvard, and I have no time to observe a hen."
No time to notice a hen? My friend, did you ever try to talk with her?
"No, I did not; she has no language."
Didn't you ever hear her call the chickens and see them come? Didn't you ever hear her scold the rooster, and see him go? Well, a hen does have a real language, and it is time you scientific professors understood what that old biddy says.
