But it is less as a hymn- than as a tune-book that "Church Pastorals" merits the notice of societies and individuals who are truly interested in religious music, and we pass at once to our remarks upon this portion of the work. The compiler, although holding himself personally responsible for every selection, has availed himself of the advice and assistance of persons professionally eminent in sacred music, one of whom placed at his disposal a library which is unique in this country, containing works of which few Americans have owned or seen duplicates, such as rare "Choral-Buecher" of German cathedrals, and curious collections of English ecclesiastical compositions, a partial list of which is included in the volume, for the benefit of those who are curious in such matters, or wish to know how far Dr. Adams's researches have led him. To ascertain how many new melodies of the purest devotional character have been derived from these rich sources a careful examination is necessary, as also to comprehend with what skill the harmony has been preserved or adapted, in order to secure the two desirable results,--absolute freshness and beauty of treatment, and practicability for ordinary use; but a casual inspection will give sufficient indication of the spirit in which the work was undertaken, and of the faithfulness with which it has been completed. While originality has been properly sought, the old, familiar elements have not been neglected, and those simple songs which were upon the lips of our parents and grandparents, and are yet dear to us from association and intrinsic worth, are set in among the newer strains. The first lines only are given of such as need merely to be recalled to the memory of any who ever sing; but of others, equally prized, but less likely to be remembered, the full score is given. The doxologies are for the most part set to noble chorals of such strong, straightforward character that they cannot fail to become friends and intimates at once. In them, as in all the tunes, the compass of ordinary voices has been considered; and although nothing has been left undone which could give beauty to melody or scholarly variousness to harmony, the whole has been brought within the range of all singers. A novel and peculiar feature of the book is its "Stanzas to be sung _impromptu_." Occasions often arise at social meetings or special services, when it becomes desirable to sing a portion, or even the whole, of some homely, hearty hymn, but, while "the spirit moves," the opportunity is lost in the search for the words or the fit air, or in an attempt to "set the tune." To meet this want, Dr. Adams has brought together a variety of such stanzas, suited to all times and places, and, coupled with each, the first line of a familiar melody, that the propitious moment may be enjoyed and improved.
