when i ust to lean above it on the old sickamore,
oh! it showed me a face in its warm sunny tide
that gazed back at me so gay and glorified,

my shadder smilin' up at me with sich tenderness.
but them days is past and gone, and old time's tuck his toll
from the old man come back to the old swimmin'-hole.
