Thoreau's writing style

Thoreau's writing style is dense with metaphors, and filled with sentences that pile on observation after observation, and reflection upon reflection, until, before you know it, you've gotten to the end of the paragraph without crossing period. Not surprisingly, his main source for metaphor is the natural world around him. When he is describing nature, he often personifies or anthropomorphizes what he sees, as if all the animals, birds, plants, and even the pond have distinct personalities.
