It's been a while since I've read the book and I don't really a lot of the context, so just from this passage I would say it says he notices nice houses and other people's wealth and maybe envies them a little bit. (although you don't get that explicitly from this passage.)
When they get married they will aquire the last name of their partner
The wind caresses each leaf as she blows by
Wisping through each blade of grass and grain
Helping every beautiful baby bird take flight
Though Her beauty could not compare
An underlying rage was unforeseen
thrashing trees and bees
leaving families astray
To wonder,
wait.
