Pg. 93: In this part, Fredric writes "I told him I did, come what I might; that he had used me like a brute for 6 months..."
Pg. 99: In this part, Fredric writes "...that the religion of the south is a mere covering for the most horrid crimes,--a justifier of the most appalling barbarity..."
Pg. 94-95: In this part, Fredric writes ""Come, come! move, move! and bowse this timber forward."--"I say, darky, blast your eyes, why don't you heat up some pitch?"-- "Halloo! halloo! halloo!" (Three voices at the same time.) "Come here!--Go there!--Hold on where you are! Damn you, if you move, I'll knock your brains out!"
I think this is Analogy because Fredric is comparing himself to a brute in the eyes of Mr.Covey when he was just a slave that didn't deserve it.
I think this is Analogy once again for how he is comparing religion covering crimes to things like "...a sanctifier of the most hateful frauds..."
