"This was one of the great days; though the sky had from my clearing only the same everlastingly great look that it wears daily, and i saw no difference in it." P.128

(E) Regardless of how beautiful a day may be, the events that occur are what define it as great or not. I think that's what he means to say. That or no matter what happens, great day or not, the outside's always beautiful.
