With all due respect for the most holy doctrine of utility, I really cannot see why a fellow who is taking away a wagon-load of gravel or dung should thereby obtain the right to kill in the bud the thoughts which may happen to be springing up in ten thousand heads--the number he will disturb one after another in half an hour's drive through the town. Hammering, the barking of dogs, and the crying of children are horrible to hear; but your only genuine assassin of thought is the crack of a whip; it exists for the purpose of destroying every pleasant moment of quiet thought that any one may now and then enjoy. If the driver had no other way of urging on his horse than by making this most abominable of all noises, it would be excusable; but quite the contrary is the case. This cursed cracking of whips is not only unnecessary, but even useless. Its aim is to produce an effect upon the intelligence of the horse; but through the constant abuse of it, the animal becomes habituated to the sound, which falls upon blunted feelings and produces no effect at all. The horse does not go any faster for it. You have a remarkable example of this in the ceaseless cracking of his whip on the part of a cab-driver, while he is proceeding at a slow pace on the lookout for a fare. If he were to give his horse the slightest touch with the whip, it would have much more effect. Supposing, however, that it were absolutely necessary to crack the whip in order to keep the horse constantly in mind of its presence, it would be enough to make the hundredth part of the noise. For it is a well-known fact that, in regard to sight and hearing, animals are sensitive to even the faintest indications; they are alive to things that we can scarcely perceive. The most surprising instances of this are furnished by trained dogs and canary birds. It is obvious, therefore, that here we have to do with an act of pure wantonness; nay, with an impudent defiance offered to those members of the community who work with their heads by those who work with their hands. That such infamy should be tolerated in a town is a piece of barbarity and iniquity, all the more as it could easily be remedied by a police-notice to the effect that every lash shall have a knot at the end of it. There can be no harm in drawing the attention of the mob to the fact that the classes above them work with their heads, for any kind of headwork is mortal anguish to the man in the street. A fellow who rides through the narrow alleys of a populous town with unemployed post-horses or cart-horses, and keeps on cracking a whip several yards long with all his might, deserves there and then to stand down and receive five really good blows with a stick.
