The bargeman seen in Hades as the funeral carriage crosses the Royal Canal has been "Dropping down lock by lock to Dublin. With turf from the midland bogs." Ireland's midlands contain vast expanses of glacier-scoured, rain-soaked terrain where peat, a precursor of coal, has been building up for millennia, often to depths of 20-40 feet (up to 12 meters). From time immemorial human beings have sliced peat out of the midlands' "raised bogs" (rounded, water-logged hills that once lay beneath marshes), stacked it to dry, and then burned it for heat. Starting in the 19th century, much of this "turf" was shipped to Dublin on barges.
