Which One Came From Tennessee

We have traveled to thirty-seven states, the youngster told me. He is only eight, so this is quite the accomplishment. I collect one rock from each state, want to see them? His mother rolls her eyes, as if it is no big deal. It is a big deal to me; I am also a rock collector. Sure! He takes me into his room and pulls a box out from under his bed. I imagine mica, feldspar, gypsum, glitters of bloodstone and the like. He opens the lid. The rocks are gray, chalky, and gravel. “Which one came from Tennessee?” I ask him. He says “I have absolutely no idea, but aren’t they amazing?” I think I’ll get him a bag of gravel for his birthday.
