What is the subject of Amy Lowell’s “St. Louis”?

The subject of Amy Lowell's poem "St. Louis" is not only
about the city of St. Louis, but it is also about New England. Her present situation
(St. Louis) is contrasted to her past (New England). The first stanza vividly depicts
the summers of St.Louis, while the second reflects upon New England. In the third
stanza, the two different locations are shown using rapid images of
each.

Readers know that she is located in St. Louis
currently because she uses the words "now" and "here." Both of these words allow the
reader to know that St. Louis is where she is currently
at.

Basically, even though Lowell never specifically
mentions St. Louis in the body of the poem, readers can assume that she is talking about
the location from her descriptions of the landscape. In the same way, Lowell alludes to
New England. She speaks of "lands of hills", "tired farm-houses", and "old meeting
houses."

Lowell is reminiscing about her time in New
England contrasting the differences between her current location and her past location
(the one she dreams of and misses deeply).
