I’m a huge fan of children’s literature. I’m in three children’s literature reading groups, and I read that literature all the time. So naturally one of my favorite writers is Laura Ingalls Wilder. Her Little House books are masterpieces. The passage I read can be found in The Selected Letters of Laura Ingalls Wilder, in a letter from Laura Ingalls Wilder to Rose Wilder Lane, March 23, 1937:

You can see that all of this cost money. I would have no idea how much. I know Pa sent money home for doctor bills after he was working for the railroad. But Pa was no businessman, He was a hunter and trapper, a musician and poet.
