A Furtber Range contains "Design," arguably one of the best sonnets ever written by an American poet. It is a frightening poem, one that confronts the dire possibility that the universe is not only godless but that God is evil. In keeping with the Imagest tendencies in modern poetry, Frost centers the poem on a picture . . . .
The white spider — already a freak of nature - has landed on a white flower with a white moth in its grip. None of these three elements is normally white, which gives each of them an abstract eeriness. The fact that these elements are "mixed ready to begin the morning right, / Like the ingredients of a witches' broth --" is deeply ironic: indeed, the language parodies the language of breakfast cereal ads. What we get here is an image that combines death and blight. There is nothing life-enhancing about anything in this piece of nature.
In the sestet of the sonnet, where issues raised in the octet are traditionally resolved, Frost simply offers three haunting and unanswerable questions:
What had that flower to do with being white, The wayside blue and innocent heal-all? What brought the kindred spider to that height, Then steered the white moth thither in the night? What but design of darkness to appall? -- If design govern in a thing so small.
The poem is in many ways the key to Frost's universe, a poem so perfect in its execution that one cannot imagine a word placed otherwise. Frost's tone is deftly controlled throughout, with the poet's serious point balanced nicely by the parodic language of the first stanza. Ever aware of the linguistic roots of words, Frost is inwardly winking when he uses the word "rigid" to modify "satin cloth." Likewise, at the end, he is certainly aware (as a former Latin teacher) that the word "appall" means "to make white" in its root sense. And Frost is delighting in the way he can wring an unexpected turn of meaning from the Classical argument from design.
