One of the most significant aspects of this poem is the way that it uses powerful images to build up a picture of the healing, calming influence of nature on the soul. This is after all the importance of this island to the reader in the way that it represents a place that is completely separate to and different from his normal life in the city, defined by its "pavement grey" and generally by a lack of colour and tranquility. Note how the second stanza builds up an image of nature as being calming and soothing:
And I shall have some peace there, for peace comes dropping slow,
Dropping from the veils of the morning to where the cricket sings;
There midnight's all a glimmer, and noon a purple glow,
And evening full of the linnet's wings.
The island is defined by the nature that encompasses it, with evening described as being "full of the linnet's wings" and peace is imagined as "dropping from the veils of the morning," because it is so tangible the speaker imagines that he can see it and reach out and touch it. Note too the alliteration in "glimmer" and "glow" which help to create the songlike feel of the poem and the attractive site that the poet is describing. The poem also makes use of assonance to reinforce its strong rhythmic qualities. The speaker can almost be imagined to chant this poem to himself as he goes about his business in the city, and he uses the powerful images in this poem to sustain him and strengthen him in the face of the "pavements grey" and the oppressive toil of materialistic society.
