View from a College Window

[just mercedes]

I like the circular nature of your poem - starts and ends with rain, so very British. I like the empty feeling, the mood of solitary contemplation which the scene echoes. If it is a familiar scene, as the title suggests, then why does the narrator 'assume' what is there but not seen?

A dirty window blocks the wind and rain,
but through it I see their bleak effects [I like the sounds blocks/bleak but find 'bleak' too telling somehow]
on houses and trees and [lawn arrangements.] arrangements of the lawn, or on the lawn?
A rotten rusting white metal chair, - too many descriptives in a row
beside its fellows [of brotherly creed.] tautology?
Around a central table, I assume,
though large and ragged trees obscure my view.[I think someone else commented on how much you can see, though blocked by dirty window and trees - does feel a bit weak]
[Appropriately sad, I think] - this feels intrusive, even though the whole scene is seen through the narrator's eyes - try without it
a lawn
for entertaining guests [in summer or
the spring,] - in better weather? now wilting darkly in the rain.

I think your poem is a good example of how 'tone' can project a mood or emotion with a simple description of place.
