Answer:
Hey there!
Your answer would be: "All day he hung round the cove or upon the cliffs with a brass telescope; all evening he sat in a corner of the parlour next the fire and drank rum and water very strong."
Not only does this give a reader of where the man lives, but also contributes to the mood of the story, and makes me think that the man is an isolated person, who prefers solitude.
Hope this helps!
