This poem is a dirge for a landscape that Hopkins had known intimately while studying at Oxford. Hopkins here recapitulates the ideas expressed in some of his earlier poems about the individuality of the natural object and the idea that its very being is a kind of expression. Hopkins refers to this expression as ‘selving,’ and maintains that this ‘selving’ is ultimately always an expression of God, his creative power. The word appears here (as ‘unselves’), and also in ‘As Kingfishers Catch Fire.’ Here, Hopkins emphasizes the fragility of the self or the selving: Even a slight alteration can cause a thing to cease to be what it most essentially is. In describing the beauty of the aspens, Hopkins focuses on the way they interact with and affect the space and atmosphere around them, changing the quality of the light and contributing to the elaborate natural patterning along the bank of the river. Because of these interrelations, felling a grove not only eradicates the trees, but also ‘unselves’ the whole countryside.

The pricked eyeball makes a startling and painful image; in case the readers have not yet shared Hopkins’s acute pain over the felled poplars, the poet makes sure we cringe now. The image suggests that when the trees disappear from sight, the ramifications are as tragic as the loss of our very organ of vision. The implication is that we are harmed as much as the landscape; Hopkins wants us to feel this as a real loss to ourselves. Not only will the landscape not be there, but we will no longer be able to see it—in this way, it really is as if our eyes were punctured.

For Hopkins, the patterning of the natural world is always a reflection of God and a mode of access to God; thus, this devastation has implications for our ability to be religious people and to be in touch with the divine presence. The narrowness of the industrial mindset loses sight of these wider implications. Hopkins puts this blindness in a biblical context with his echoes of Jesus’ phrase at his own crucifixion: ‘Father forgive them, for they know not what they do.’
