What are the promises that Mary Call makes to her father?

Mary Call has promised him a homemade burial, without an undertaker or preacher. This is a difficult promise, because she will have to pull his body up the mountain in her brother's toy wagon. The second promise is that Mary Call will keep her family together on the mountain. Plus, they will not accept charity from strangers. The last promise that Mary Call has made is that she will not let Devola marry Kiser Pease.
