—Your theory of no pictures should appeal to the publishers but I doubt if the illustrators will stand with you.
—Illustration is a trade as well as an art.
—True. But we are trying to limit the inquiry to the artistic side at present. When, then, according to your deductions, would illustrations be called for?
—When they can make a stage-setting for the story. When they ornament it or suggest it, perhaps, instead of reveal it. Impressions and "atmosphere" instead of literal diagrams with a cross marking the spot where, etc.
—But perhaps people like the cross marking the spot where.
—We are limiting the discussion to the artistic side, are we not?
—What about the half-tone process of engraving?
—The process is a way of doing a thing that cannot be done cheaply by any other means.
—Do you consider it a process that adds to the artistic possibilities of book printing?
