If you have the 1991 Denson edition, 284 is GARDEN HYMN. I am as sure of it as that my name is Squeaky. In any case this is the song Moira Smiley sang. Follow the Artful Codger's link to the three-part Southern Harmony version and you will see.

Sacred Harp singers have been using the Denson 1991 edition since, well, 1991, and the book hasn't yet been revised, so I know it well. I don't know if GARDEN HYMN has ever been on a different page of the SH, though. Here is a recording from a recent Sacred Harp singing, last year's convention in Cork, Ireland.
