_MUSIC._ LEIGHTON was composed by Henry Wellington Greatorex, 1811-58, an Englishman by birth. Coming to the United States in 1839, he served as organist at Central Congregational Church, Hartford, Conn., in St. Paul’s and Calvary Churches, New York City, and finally in an Episcopal Church at Charleston, S. C. He edited the _Greatorex Collection_ of 1856 and did much to improve the standards of music used in the worship service. He composed a widely used setting for the “Gloria Patri” (606). Dr. Merrill’s hymn has been set to various tunes, the one generally used and preferred by the author being “Festal Song,” by William H. Walter. 231. Go, labor on; spend and be spent _Horatius Bonar_, 1809-89 A hymn to encourage Christian workers. It was published in _Songs for the Wilderness_, 1843, under the title, “Labour for Christ.” In _Hymns of Faith and Hope_, 1867, it was entitled, “The Useful Life.” Regarding the origin of the hymn, Rev. H. N. Bonar, son of the author wrote: It was probably in the year 1836 that my father first wrote a hymn not primarily intended for the young. To encourage his faithful fellow workers in his mission district, he wrote, to the tune of the “Old Hundredth,” the now-familiar hymn, “Go, labour on.” For comments on Horatius Bonar see Hymn 129. _MUSIC._ ERNAN was written for _Cantica Laudis_, 1850, one of the books which Mason published with the assistance of Geo. J. Webb. For comments on the composer, Lowell Mason, see Hymn 12. THE INNER LIFE 232. O have you not heard of that beautiful stream _R. Torrey, Jr._ Based on Rev. 22:1, 17: “And he showed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb.” “And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely.” It is reminiscent also of Ezek. 47:1-12, the vision of the healing stream of water flowing from the house of God to the Dead Sea, causing new life to flourish. “Everything shall live whither the river cometh.” (v. 9). An omitted stanza reads: With murmuring sound doth it wander along Through fields of eternal green; Where songs of the blest, in their haven of rest Float soft on the air serene.
