Last week on my way home from buying groceries, I passed a cotton field. It’s ready for harvest. The bolls are open and the plants look like they are covered with snow. Until I moved South, I didn’t realize cotton was harvested in the late fall and early winter. I teach about the role of King Cotton in the economy of the antebellum South. I tell my students about the invention of the cotton gin by a Yankee and show them pictures of slaves picking cotton, bags slung over their shoulders. In another class, we talk about what happened to agriculture in the South once slavery was abolished and tenant farming and sharecropping dominated. And when we discuss the New Deal, I show them pictures from the Farm Security Administration’s photography project that includes images of cotton pickers from the 1930s.

But the thing is, lots of threads get lost and nobody goes to find them. And that got me to thinking about the ways in which knowledge and skills are bequeathed from one generation to another:
Why do some skills get lost and others survive? Continue reading
