Oh, and the next two hours tripped by on rosy wings. Forget the hashed metaphor.
(part 4, paragraph 5 in the reference above)
I fail to understand what the hashed Metaphor is, in the context of this story. Apart from this line, the rest of the plot is clear to me (and so is the context). I found a reference according to which the metaphor was actually a mixed metaphor, but I am not well-versed with the types of metaphors and their relative differences (or meanings). I also went through a reference which stated that this metaphor might have stemmed from the fact that this story was written while meeting a strict deadline. I fail to see the connection between the meaning of this metaphor and the haste with which it might have originally been written.
