How do the Luthers prepare for winter?

The Luthers prepare for winter by having a store of food in the house including squashes, cabbages, and salted pork, along with dry goods like flour and dried beans, but Mary Call still worries that it will not be enough to last them the long five months of winter. She is also worried about the house, which is drafty and needs repair. They've stacked up fire wood on every wall, and brought the pig and rooster inside.
