They have a somewhat ponderous hymnology, in two great volumes, one called "The Voice from Zion: to the Praise of the Almighty," by "John William Petersen (A.D. 1698)," printed at Eben-Ezer, N. Y., in 1851, and containing 958 pages. The hymns are called Psalms, and are not in rhyme. They are to be sung in a kind of chant, as I judge from the music prefixed to them; and are a kind of commentary on the Scripture, one part being taken up with the book of Revelation. The other volume is the hymn-book in regular use. It contains 1285 pages, of which 111 are music--airs to which the different hymns may be sung. The copy I have is of the third edition, and bears the imprint, "Amana, Iowa, 1871." Its title is "Psalms after the manner of David, for the children of Zion." It has one peculiarity which might with advantage be introduced in other hymn-books. Occasional verses are marked with a *, and it is recommended to the reader that these be taught to the children as little prayers. In practice, I found that in their evening meetings the grown persons as well as the children recited these simple and devotional little verses as their prayers: surely a more satisfactory delivery to them and the congregation than rude and halting attempts at extemporary utterance. Many of the hymns are very long, having from twelve to twenty-four verses; and it is usual at their meetings to sing three or four verses and then read the remainder. They do not sing well; and their tunes--those at least which I heard--are slow, and apparently in a style of music now disused in our churches. The hymns are printed as prose, only the verses being separated. I was told that they were "all given by the Spirit of God," and that Christian Metz had a great gift of hymn-writing, very often, at home or elsewhere, writing down an entire hymn at one sitting. They are all deeply devotional in spirit, and have not infrequently the merit of great simplicity and a pleasing quaintness of expression, of which I think the German language is more capable than our ruder and more stubborn English. Their writers are greatly given to rhyming. Even in the inspirational utterances I find frequently short admonitory paragraphs where rude rhymes are introduced. Among their books is one, very singular, called "Innocent Amusement" ("_Unschuldiges Zeitvertreib_"), in a number of volumes (I saw the fifth). It is a collection of verses, making pious applications of many odd subjects. Among the headings I found Cooking, Rain, Milk, The Ocean, Temperance, Salve, Dinner, A Mast, Fog, A Net, Pitch, A Rainbow, A Kitchen, etc., etc. It is a mass of pious doggerel, founded on Scripture and with fanciful additions. Another is called "Jesus's ABC, for his scholars," and is also in rhyme. Another is entitled "Rhymes on the sufferings, death, burial, and resurrection of Christ." There are about twelve hundred pages of the ABC book.
