Five hundred and seven mechanical movements

"The selection of the movements embraced in this collection has been made from many and various sources. The English works of Johnson, Willcock, Wylson, and Denison have been drawn upon to a considerable extent, and many other works—American and foreign —have been laid under contribution; but more than one-fourth of the movements—many of purely American origin—have never previously appeared in any published collection. lthough the collection embraces about three times as many movements as have ever been contained in any previous American publication, and a considerably larger number than has ever been contained in any foreign one, it has not been the object of the compiler to merely swell the number, but he has endeavored to select only such as may be of really practical value" - from the preface of the 21st edition.
