The end of the Scarborough scene is closed by a tree. The men board their ships and make their way down the coast to the mouth of the Humber estuary. The Humber was a major boundary, separating Northumbria from the southern kingdoms. The Humber today forms the boundary between the East Riding of Yorkshire and Lincolnshire. The world's fifth longest suspension bridge (7,283 ft.) now crosses the Humber. There are four deer represented in this scene. Two in the top border and two in the lower border. They represent the four winds corresponding to the four stags of the cosmic tree Yggdrasil.
