From the sheet music at the University of Tennessee Knoxville:


GRACE DARLING
Music by W. Walmsley, Jr.
Arranged by Prof. J. Drew, P[or]t Burwell, C. W. *
Published by Root & Cady, Chicago, Ill. [no date]

1. Oh, Father dear, the storm is raging,
Cold and damp the night mist falls,
Some helpless crew a prey to danger,
For help, for help, despairing calls!

CHORUS: Trim the lamp; the boat launch quickly, the boat launch quickly.
Though danger threatens, the worst we’ll brave.
The toil heed not, if we but rescue
The shipwrecked wander’s[wand’rers?] from the grave.

2. My child, it would be worse than madness
To tempt the waves this fearful night;
To sleep, to rest, again betake you.
Await, await the morning light.

3. I cannot sleep; their shrieks appall me.
Oh, heard you not that fearful cry?
Afar I see the day is breaking.
Look out, look out, the wreck I spy!

4. The boat is launched ’mid billows breaking,
Like some wild bird that frail boat flew;
The gentle girl with love unshaken
Has saved the hapless shipwrecked crew.

5. The gentle Grace, so young and lovely,
No silent joy her heart betrays,
Though grateful tears are round he falling,
And hearts are beating to her praise.

* C. W. = Canada West a.k.a. Upper Canada, which was the term used from 1841 to 1867, after which Ontario was formed—which helps to date the song. Root & Cady operated from 1858 to 1871. So this puts the publication date between 1858 and 1867.
