"My granddaddy built the shed." He said it as information without any pride attached to it at all. And then he drove home.

Wendell Prine retired in 2002. Cordell came to the gathering they held for him at the counter on a Saturday morning, which was the only appropriate time. He did not make a speech. He shook the man's hand and said he had learned a great deal from a conversation they had in 1989.

Wendell looked at him. "You learned it in spite of me, not because of me." Cordell answered, "You told me what I'd have to prove."

They shook hands again, and that was the end of it.

Let me tell you about Alton Tarver because I have not given him enough of this story, and he has earned more. He farmed those 160 acres until his knees made it impractical, and then he spent the last years of it doing what he had always done in the lean-to, taking things apart, working out why they failed, putting them back together, mostly for neighbors, mostly for nothing. He died in March of 2008 at 79 in the farmhouse where he had been born.

The obituary in the Camden paper ran four paragraphs. It did not mention the shop. It did not mention the wall. It did not mention $522,000 that stayed in Wilcox County because his son had paid attention to what he was taught.

Alton Tarver would not have considered any of that worth putting in an obituary. He would have said that a man does his work, and the work speaks or it doesn't, and either way the man is gone and the work is still standing there. The lean-to Purvis Tarver built in 1938 is still standing. Cordell maintains it the way Purvis maintained it and Alton maintained it, not as a museum, but as a working building because a shed that isn't used is just a structure, and a structure that isn't used falls down.

The bench where a 14-year-old boy took the case off a welding machine in March of 1987 is still in there. And so is the parts bin on the north wall, still labeled in Purvis Tarver's handwriting from 1974, supplemented now in a second hand by his grandsons.

In the spring of 2013, Cordell Tarver's daughter walked into the shop with a notebook under her arm. Simone Tarver was 16 years old, which was exactly the age her father had been the summer he first started thinking seriously about what 4 cents a pound was actually worth. She told him she had been reading about airflow and cure cycles. She said the booth was moving air wrong for the volume it held and that if the intake and the baffling were reconfigured, the 9-day finish cycle could come down to 3 days for most of what came through it.

She said that would put roughly 30% more work out the door without buying a single piece of equipment. She said she had run the numbers and that they were in the notebook. Cordell Tarver looked at his daughter. Then he looked at the notebook. And he thought about a yellow legal pad and an afternoon in a library in Tuskegee and a gooseneck coupler on a counter and a man who had laughed.

"Show me the numbers." She handed him the notebook. He read it standing up all the way through and then he went back and read part of it again. "We'll build the test booth this summer."

Simone looked up. "Really?" Cordell nodded.

"You did the work." He handed the notebook back. "We do the work. That's how it goes."

"Cody Prine told me last week these booths ain't worth fooling with." Cordell wiped his hands and did not look up. "Good. Now you know exactly what you've got to prove."

Simone Tarver built the test booth that summer. The reconfigured airflow brought the cure cycle down to 3 days. Throughput went up 34%, slightly better than she had projected. She wrote the results in the notebook and the notebook went on a shelf in the equipment shed.

It sits there now next to three other pieces of paper, a parts bin label in Purvis Tarver's hand from 1974, a yellow legal pad from 1989, and a business registration form filled out at the Wilcox County Courthouse in 1991 because a woman named Odessa made her son write his own name across the top of it.

Four pieces of paper. One shelf. Three generations.

Tarver Iron and Repair is still running. The experts still say the model doesn't work in a county like that one. Not enough capital. Not enough volume. Not enough of anything.

The Tarvers have been proving them wrong for better than 25 years. One weld at a time. On machines everybody else had already declared dead.

He asked for your broken machines. They laughed. He built the shop. The shop ran. The work paid. And the money stayed home.
