Just in case anyone doesn't know what the Liffey is (I didn't). It's a river in Ireland. Info from Wikipedia. Also referenced by Joyce in Ulysses: "A skiff, a crumpled throwaway, Elijah is coming, rode lightly down the Liffey, under Loopline Bridge, shooting the rapids where water chafed around the bridgepiers, sailing eastward past hulls and anchorchains, between the Custom House old dock and George?s quay." And in Finnegan's Wake: "riverrun, past Eve and Adam's, from swerve of shore to bend of bay, brings us by a commodius vicus of recirculation back to Howth Castle and Environs."
