"Field Work" Reading Respons

"and your veins to be crossed criss-cross with leaf veins" (Heaney, 47).

The poem Field Work by Seamus Heaney has many references to nature.  The title of the piece is also the same title of the entire book of works.  I thought that this quote was very interesting because it incorporates both humans and nature.  If one were to literally criss crossing their veins with the veins of the leaf they would become so committed to nature. The final stanza of this poem talks about staining the back of your hand with the pigment of the flower.  As though you are becoming one with nature.  Also I thought that it was interesting how in the beginning of the poem it talked about being wounded by marks from vaccination, and then at the end of the poem it refers to being stained to perfection.  And you don't normally refer to things that are stained to be perfect. I think that the title of the poem refers to both literal field work and experimenting.  When someone is working with their hands and with nature they are said to be doing field work.  Also if someone is doing research and collecting data they are doing field work.  The narrator is working close with nature and trying to become close with this character that he is watching at the beginning.  I wonder why Seamus Heaney choose this poem to also be the title of the entire book of poems?
