“Kabnis, a promise of soil-soaked beauty; uprooted, thinning out. Suspended a few feet above the soil whose touch would resurrect him.
Toomer, Jean. “Kabnis.” Cane. New York: Liveright, 2011. 132. Print.
This is one of the connections I found from the story of Kabnis, it can be tied to the poem Harvest Song which is all about this sense of working in the soil, which is what Harvest Song is all about. But at the end of Harvest Song, the last stanza mentions “I fear to call.” I believe he must be referring to someone, just like how Kabnis, when talking about this soil, is actually talking about how he feels towards Lewis.
