Had to look for the missing details and here is my answer.

Based on the allusions made by the author in Midsummer to "the child's fairy tale," "fairy rings," and "thatched cottages fenced with dog roses," we can say that the speaker "feels that an idealized version of England does not exist." "Midsummer" is actually written by Derek Walcott. Hope this answers your question.
