Kindly Spring again is here. J. Newton. [Spring.] The hymn in The Council School Hymn Book, 1905, is a cento, stanzas i.-iii. being from J. Newton's "Pleasing spring again is here," Olney Hymns, 1779, Bk. 2, No. 33, somewhat altered, and st. iv. by another hand. In The English Hymnal, 1906, there is another cento beginning with the same altered first line.
