The night Thorough spent in Jail

In act one of "the night thorough spent in jail", huckleberries are used as symbolism. I think that they are a symbol that says despite the fact that a peaceful man is stuck in Jail, the world is still full of wonderful, nice things. They were also mentioned in Henry's teaching, he uses the Huckleberry method, which is basically sending them in the right direction, then letting them go on their own.
