Yes, it is one of the curious and new impressions of travel to an American to find large trees growing in European ruins. At the old Schloss at Baden Baden, they are found growing in what must have been the parlors; at Heidleburg the same curious facts strike the traveller in the old castle. Where ladies received the returning warrior knight the walls still stand uninjured; but trees of considerable size grow where the footfalls of ladies and their admirers figured in times not extremely ancient. So at Verona, the Coliseun built of enormous rocks, considerable trees have taken root high up in the walls, and wave their branches in every wind. So the American finds constant surprises at things he never saw at home.
