There'll be no dark valley when Jesus comes. [Light at Eventide.] Cocerning this hymn, in Sacred Songs and Solos, 1903, Mr. Sankey says, in his My Life and Sacred Songs, 1906:—
"I arranged this hymn from the words which Mr. W. O. dishing wrote for me, of which, however, I used only the first line, 'There'll be no dark valley when Jesus comes.'"
Its proper ascription is "W. O. Cushing and I. D. Sankey."
