There are two kinds of critics of such work as ours. First there is the wide public for whom we work and by whom we are paid; "who lives to please must please to live"; and who lives by drawing for a comic periodical must manage to please the greater number. The judgment of this critic, though often sound, is not infallible; but his verdict for the time being is final, and by it we, who live by our wits and from hand to mouth, must either stand or fall. The other critic is the expert, our fellow-craftsman, who has learned by initiation, apprenticeship, and long practice the simple secrets of our common trade. He is not quite infallible either, and is apt to concern himself more about the manner than the matter of our performance; nor is he of immediate importance, since with the public on our side we can do without him for a while, and flourish like a green bay-tree in spite of his artistic disapproval of our work; but he is not to be despised, for he is some years in advance of that other critic, the public, who may, and probably will, come round to his way of thinking in time.
