According to “economy” from walden, what happened before the framing of thoreau’s house was completed?

Thoreau borrowed an axe and spent some days gathering things needed in framing his house. He cut and hew timber, studs, and rafters without thinking about  many things but the essence of nature. He made more familiarity of the trees and enjoyed the company of nature while preparing the woods needed to build his house.

the excerpt from chapter 2 of "animal farm", by george orwell that is an example of foreshadowing is "these three (snowball, napoleon, and squealer) had elaborated old major's teachings into a complete system of thought to which they gave the name of animalism." animal farm is an allegory of how czarist russia developed into communist russia with all its corruption. old major's teachings represent marx's theories turned into communism, animalism, by the three pigs. this foreshadows the oppression and corruption that will follow this revolt.

im not entirely sure what you're asking.
