He helped her move the hose.
They ran the diesel pump only long enough to transfer water into the elevated storage tanks.
Then shut it off.
The drip system distributed that stored water slowly for many hours.
That changed the economics.
Instead of operating a pump continuously to maintain sprinkler pressure, they could run it briefly during dry periods, fill storage, and let gravity handle delivery afterward.
Della wrote that down.
The original idea changed.
She did not consider that failure.
She considered it learning.
By early August, differences appeared.
Not dramatic at first.
The quarter-acre test plot remained greener during afternoons.
Leaves stayed flatter.
Soil beneath the drip lines remained darker.
Harlan compared roots.
Plants in Della’s section showed less drought stress.
He refused to say much.
Della noticed him walking the rows more often.
One evening he came inside carrying her notebook.
“How much water are you using?”
She told him.
“Check it again.”
“I did.”
“Compared to sprinkler?”
“About forty percent.”
“Forty percent less?”
“No.”
She looked at him.
“About forty percent of what you used on the comparable area.”
Harlan stared.
“That’s sixty percent less.”
“Yes.”
“Are you sure?”
“No.”
That answer pleased him.
“Why not?”
“Because your sprinkler comparison wasn’t exactly the same week and wind was different.”
Harlan smiled.
“Good.”
“Good?”
“You’re learning not to make claims bigger than your data.”
Della took the notebook.
“I think it’s somewhere between forty and sixty percent less.”
“That sounds more believable.”
Then Harlan asked the question she had waited all summer to hear.
“You want to extend it?”
Della looked up.
“To where?”
“The rest of the upper half-acre.”
Her eyes widened.
“You mean it?”
“If you can do it without spending stupid money.”
“What is stupid money?”
“We’ll discuss that before you spend it.”
That became the first expansion.
Then the east section.
Not acres all at once.
Small blocks.
Della learned that scaling created new problems.
Pressure balance became harder.
Longer runs needed careful sizing.
Storage disappeared faster.
The bigger system needed valves so sections could be irrigated separately rather than starving every emitter simultaneously.
Wendell helped with manifolds.
Clifton suggested inexpensive pressure-compensating components only where absolutely necessary.
Harlan contributed old pipe he had previously refused to sacrifice.
Cass eventually stopped making fun of the project and started helping.
Not willingly at first.
His conversion occurred because of a broken bicycle chain.
Della fixed it.
Cass stared at her hands.
“You know how to do that?”
“It’s a chain.”
“On a bike.”
“Still a chain.”
After that he began helping move pipe.
He never admitted those events were connected.
By late August, Calloway County had gone forty-two days with very little meaningful rain.
Roadside grass turned brown.
Corn leaves rolled tightly in the afternoon.
Several neighbors chopped fields early for silage rather than risk losing everything.
Harlan’s lower soybean ground suffered.
The upper test section should have suffered worse.
Instead, it looked better.
Deep green leaves.
More uniform canopy.
Plants standing upright late into the day.
Pod set appeared heavier.
The contrast became visible from the road.
That was when people started coming back.
Curtis Bell arrived first.
He had given Della six leaking pipe sections in June.
He parked at the edge of the field.
Walked fifty yards.
Stopped.
“What did you put on these?”
Della looked confused.
“Water.”
Curtis stared at her.
“I know water.”
She showed him.
The tanks.
