When a herd of cattle see a strange object, they are not satisfied till each one has sniffed it; and the horse is cured of his fright at the robe, or the meal-bag, or other object, as soon as he can be induced to smell it. There is a great deal of speculation in the eye of an animal, but very little science.

Though builders may build, in the main they follow the plans of architects. Teachers teach, but they must have a text. Politicians govern, but only upon the flow of commentary that raises them up or casts them down.
