What analogy or comparison can you make between the central idea thoreau expresses in "the pond in winter" and in "spring" in what ways are the ideas in these two passages similar and different?

In both passages Thoreau is expressing nature and its importance it has for him. Both describe the life, the pond, and the beauty of how it changes in the seasons. "Spring" also mensions death. Thoreau talks about how he spotted a dead horse yet it represented nature and the cruel things it can do.
