            I have always held that no art can be taught by books, and that an artist's best way of teaching is directly and personally to his own pupils, and maintained these things stubbornly and for long to those who wished this book written. But I have such respect for the good judgment of those who have, during the last eight years, worked in the teaching side of the art and craft movement, and, in furtherance of its objects, have commenced this series of handbooks, and such a belief in the movement, of which these persons and circumstances form a part, that I felt bound to yield on the condition of saying just what I liked in my own way, and addressing myself only to students, speaking as I would speak to a class or at the bench, careless of the general reader.
