The conversation between madame valmonde and desiree gives an example of Foreshadowing; situational irony; Considering this Quote; Madame Valmonde "shuddered at the first sight of it.....It was a sad lokking place.......The roof came down steep and black like a cowl, reaching out beyond the wide galleries that encircled the yellow stuccoed house. Big, solemn oaks grew close to it, and their thick-leaved, far-reaching branches shadowed it like a pall."
The imagery in this quote reveals the darkness of a place that is ironically called a shelter, and Madame Valmonde mentions the "pall" that is cast over the house , that being a term related to death.
You take any of the "signs of change in populations of organisms and their environments". For imagine, Australopithecus (early man) turning to Homo sapiens. In that way they could tell that you took this journey.
