In the tenth stanza, the poet is presenting a picture of decay and rot. This decay and rot was not confined to the surface only but went to the ‘very deep’ of the ocean. Slimy thing at crawled upon the muddy and sticky sea. In the eleventh stanza, the poet introduces the supernatural in the poem. ‘The death fires danced at night’. The water burnt green, blue and white ‘like a witch’s oils’.
