GARDNER. _Editorial_ Some of the numbers of The Mentor have been used as the subject matter for reading clubs. That is a use of The Mentor that we most heartily welcome. We have information from one reader that the number of The Mentor on “Spain and Gibraltar” is to be used at the next meeting of a literary club in the home of the writer. This number is to be read in conjunction with a study of Washington Irving’s books on Spain--“The Alhambra” and “The Conquest of Granada.” Another club has used the article on “Dutch Masterpieces” as the core of its evening’s study, and we have it from a reader that he knows that number of The Mentor “almost by heart.” No better thing could be said of The Mentor than that it is worth knowing by heart. It means that The Mentor has become to some readers at least a fund of important information--a fund that they can literally absorb and make their own. * * * * * The New York Sun called attention editorially, a short time ago, to the yearly report of Dr. Nicholas Murray Butler, president of Columbia University, in which he deplores “too much slovenly reading matter” as an obstacle to education, “the substitution of quantity for quality,” and recalls the fact that the great lawyers of the Colonial period and the makers of the Constitution had few, but the fittest, books; knew well a few first rate books.
