The power of the will over moods of the mind is very noticeable in children. Children often rise in the morning in any thing but an amiable frame of mind. Petulant, impatient, quarrelsome, they cannot be spoken to or touched without producing an explosion of ill-nature. Sleep seems to have been a bath of vinegar to them, and one would think the fluid had invaded their mouth and nose, and eyes and ears, and had been absorbed by every pore of their sensitive skins. In a condition like this, I have seen them bent over the parental knee, and their persons subjected to blows from the parental palm; and they have emerged from the infliction with the vinegar all expelled, and their faces shining like the morning--the transition complete and satisfactory to all the parties. Three-quarters of the moods that men and women find themselves in, are just as much under the control of the will as this. The man who rises in the morning, with his feelings all bristling like the quills of a hedge-hog, simply needs to be knocked down. Like a solution of certain salts, he requires a rap to make him crystallize. A great many mean things are done in the family for which moods are put forward as the excuse, when the moods themselves are the most inexcusable things of all. A man or a woman in tolerable health has no moral right to indulge in an unpleasant mood, or to depend upon moods for the performance of the duties of life. If a bad mood come to such persons as these, it is to be shaken off by a direct effort of the will, under all circumstances.
