There are some people who can not laugh, but these are not necessarily either morose or stupid. They may laugh in their heart, and with their eyes, although by some unlucky fatality, they have not the gift of oral cachinnation. Such persons are to be pitied; for laughter in grown people is a substitute devised by nature for the screams and shouts of boyhood, by which the lungs are strengthened and the health preserved. As the intellect ripens, that shouting ceases, and we learn to laugh as we learn to reason. The society we have mentioned studied the harder the more they laughed, and they laughed the more the harder they studied. Each, of course, to be of use, must be in its own place. A laugh in the midst of the study would have been a profanation; a grave look in the midst of the merriment would have been an insult to the good sense of the company. If there are some people who can not laugh, there are others who will not. It is not, however, that they are ashamed of being grown men, and want to go back to babyhood, for by some extraordinary perversity, they fancy unalterable gravity to be the distinguishing characteristic of wisdom. In a merry company, they present the appearance of a Red Indian whitewashed, and look on at the strange ways of their neighbors without betraying even the faintest spark of sympathy or intelligence. These are children of a larger growth, and have not yet acquired sense enough to laugh. Like the savage, they are afraid of compromising their dignity, or, to use their own words, of making fools of themselves. For our part, we never see a man afraid of making a fool of himself at the right season, without setting him down as a fool ready made. A woman has no natural grace more bewitching than a sweet laugh. It is like the sound of flutes on the water. It leaps from her heart in a clear, sparkling rill; and the heart that hears it feels as if bathed in the cool, exhilarating spring. Have you ever pursued an unseen fugitive through the trees, led on by her fairy laugh; now here, now there--now lost, now found? We have. And we are pursuing that wandering voice to this day. Sometimes it comes to us in the midst of care, or sorrow, or irksome business; and then we turn away, and listen, and hear it ringing through the room like a silver bell, with power to scare away the ill-spirits of the mind. How much we owe to that sweet laugh! It turns the prose of our life into poetry; it flings showers of sunshine over the darksome wood in which we are traveling; it touches with light even our sleep, which is no more the image of death, but gemmed with dreams that are the shadows of immortality.
