Not so in haste, my heart. [Trust in God.] Dr. W. G. Horder's note on this hymn, in his revised ed. of The Treasury of American Sacred Song, 1900, p. 367, is:—
”Wait [i.e. this hymn] has been attributed to Bayard Taylor, but I am in some doubt whether it is actually from his pen. I do not find it in his works. It appeared in the Boston Transcript about twenty years ago, signed B. T., which may or may not have stood for Bayard Taylor."
We may add that in the American Pilgrim Hymnal, 1904, it is given to Bayard Taylor, and dated 1870, but we have failed to find it in any of his works.
