Based on the given statement above, I can say that the type of comparison that is being shown is a SIMILE. A simile is a literary technique that compares two unlike objects with the use of the words "like" or "as...as". Apparently, this uses "as...as" in comparing "they" and "bark of a tree". Hope this helps.
In his memoir, Sampson Davis describes the experience of growing up in Newark. He tells us that he came from an impoverished background, and that he faced enormous difficulties and obstacles in order to become a doctor. However, even after he became a doctor, Davis believed it was important for him to come back and become a beacon of hope for other people who had grown up in the same difficult environment. He wanted to come back and show young people that it was possible for them to change their lives through education.
