A few persons have of course drifted into the exhibition out of curiosity or from lack of something better to do. So much is evident at once, for these file past the walls listlessly, seldom stopping, and then but to glance at those pictures which are most obviously like the familiar object they pretend to represent,--such as the bowl of flowers which the beholder can almost smell, the theatre-checks and five-dollar note pasted on a wall which tempt him to finger them, or the panel of game birds which puzzles him to determine whether the birds are real or not. These visitors, however, are not the most numerous. With the great majority it is not enough that the picture be a clever piece of imitation or illusion: transferring their interest from the mere execution, they demand further that the subjects represented shall be pleasing. The crowd pause before a sunny landscape, with cows standing by the shaded pool; they gather about the brilliant portrait of a woman splendidly arrayed,--a favorite actress or a social celebrity; they linger before a group of children wading in a brook, or a dog crouching mournfully by an empty cradle. At length, with an approving and sympathetic word of comment, they pass on to the next pleasing picture. Some canvases, not the most popular ones, are yet not without their interest for a few; these visitors are taking things a little more seriously; they do not try to see every picture, they do not hurry; they seem to be considering the canvas immediately before them with concentrated attention. No one of all these people is insensible to the appeal of the picturesque: their presence at the exhibition is evidence of that. In life they like to see a bowl of flowers, a sunny landscape, a beautiful woman in beautiful surroundings; and naturally they are interested in that which represents and recalls the reality. At once it is plain, however, that to different individuals the various pictures appeal in different measure and for differing reasons. To one the very fact of representation is a mystery and fascination. To another the important thing is the subject; the picture must represent what he likes in nature or in life. To a third the subject itself is of less concern than what the painter wanted to say about it: the artist saw a beauty manifested by an ugly beggar, perhaps, and he wanted to show that beauty to his fellows, who could not perceive it for themselves. The special interest in pictures of each of these three men is not without its warrant in experience. What man is wholly indifferent to the display of human skill? Who is there without his store of pleasurable associations, who is not stirred by any call which rouses them into play? What lover of beauty is not ever awake to the revelation of new beauty? Indeed, upon these three principles together, though in varying proportion, depends the full significance of a great work of art.
