The hymn is "Haven of Rest." The transcription I have is allegedly in the key of A. It goes like this: 6 8 8 8 8 -8 / 7 7 -6 7 6 / 6 7 7 7 7 -8 8 -8/ This corresponds to the lyrics, "My soul in sad exile/ was out on life's sea/ so burdened with sin and distressed/...etc. This was at http://www.net/~jackmearl/hymns/thymns/the_haven_of_rest.html
