The stone wall was the first fence. Before wood. Before wire. Before iron. Someone picked up a rock and put it next to another rock and the two rocks agreed to be a boundary. The stone wall was the first contract between neighbors. The stone wall was the first sentence the land ever spoke.

The stone walls in lower Manhattan are buried. Under the sidewalk. Under the street. Under the subway. The Dutch built stone walls to keep the English out and the wall became a street and the street became Wall Street and the street that was built to keep people out became the street that keeps money in. The stone wall is still down there. The original argument. The first line drawn.

My grandfather said every stone in a wall has a story. The stone was in a field. Someone picked it up. Someone carried it. Someone placed it. The wall is a library of labor. Every stone is a decision someone made about where the world begins and where the world ends. The stone wall is the oldest autobiography of work.

The stone wall does not need mortar. The stones hold each other. Gravity and friction. A dry stone wall can stand for three hundred years because the stones learned to lean on each other.

Nobody builds stone walls in the city anymore. Too slow. Too expensive. Too permanent. They pour concrete. They bolt steel. They hang curtain walls of glass that weigh nothing and mean nothing.

The glass wall says someone wrote a check.
