Reflecting lanterns can be used at directors' meetings as soon as corporation directors know how to read curves. By using the lantern, the president could show facts relating to the business much more rapidly, much more clearly, and with greater accuracy than would be possible with any spoken words. The showing of curves would give the directors a chance to check the president's statements so that there would be less danger than at present of a corporation president so choosing his words that, though the words might be strictly truthful in themselves, they would be over-optimistic because they did not tell all the truth. The presence of the whole file of curve cards immediately beside the lantern would enable any director to call for facts relating to any phase of the business on which he might desire information. The use of these curve cards, and a lantern, would permit a properly educated set of directors really to direct the business for which they are responsible to the stockholders.
