Here is the story on how Bishop Doane composed this missionary hymn, Fling out the banner! let if float. In 1848 there was to be a flagraising at Saint Mary's Hall, and the girls of the school appealed to Bishop Doane to write a song for them to sing on that occasion. The result was the writing of this hymn, which was sung for the first time by the young ladies of the seminary, and has been sung at thousands of missionary meetings since then, to the spiritual stimulation of many souls.
