Chapter II: Preface: To the Second Edition

SINCE the publication of this work, the author has had reason to believe that some hints as to the design and erection of small organs in country churches may be acceptable to readers who occupy the position, not of constructors, but of purchasers. He trusts that the chapter now added, "On Village Church Organs," will be found to contain the desired information.
