The American poet Robert Frost wrote about this in his poem “Mending Wall,” which is about farmers with neighboring farms.Ever spring the men get together to repair a stone wall that runs between their two properties.They walk along the wall and replace the fallen stone, “to each the boulders that have fallen to each.”However, as one farmer points out,they have no need for the well. There are only trees in that ares, no cows or other animal to keep off the other’s land
