“People help children with projects all the time.”
She nodded toward the field.
“They don’t schedule their crops around them.”
Della looked away because she did not want Opal to see how much the sentence affected her.
Three summers after Della first began collecting discarded pipe, Calloway County experienced another severe dry spell.
This time, several neighboring farms had installed their own variations.
Not copies.
That pleased Della.
Curtis Bell built a gravity-fed vegetable plot from an elevated cattle tank.
The Rowlands installed drip under plastic mulch.
Wendell helped a young farmer use a pond-side pump to fill storage during off-peak hours.
Nobody pretended one system fit everyone.
That was perhaps Della’s strongest influence.
People began asking more specific questions.
Where is my water?
Where is my elevation?
What pressure do I actually need?
What am I losing to evaporation?
What is my labor worth?
What material do I already own?
What part should be bought new?
What scale makes sense?
The old pipe pile behind the Pruitt barn gradually disappeared.
Some became working lines.
Some became demonstration pieces.
Some proved too damaged and finally went to scrap.
Della did not keep useless things just because she once believed they might become useful.
That was another skill.
Knowing when to stop.
At thirteen, she stood beside Clifton during a county field day.
Twenty-nine people came.
Della hated public speaking.
Her voice shook for the first minute.
She began by showing the first leaking coupling.
“This failed.”
Then the narrow main line.
“This failed too.”
Then a clogged drip emitter.
“This almost made me stop.”
People laughed.
Della relaxed.
She showed the final system last.
A farmer raised his hand.
“How much money did you save the first year?”
Della looked toward Harlan.
Then answered.
“We didn’t calculate a perfect number.”
“That seems important.”
“It is.”
“So?”
“We know water use was lower on the test plot.”
She gave the range.
“We know yield held better.”
She gave the comparison.
“We know Dad burned less diesel distributing water because we didn’t maintain sprinkler pressure as long.”
She paused.
“But labor was high because I was eleven and built things wrong.”
People laughed.
Harlan smiled.
Another farmer asked:
“Would you do it again?”
“Yes.”
“Exactly the same?”
“No.”
That was the answer everyone remembered.
Years passed.
Della grew.
The bicycle trailer remained behind the shed long after she became too tall to ride comfortably with it.
At sixteen, she could weld aluminum well enough to repair certain fittings.
At seventeen, she took dual-credit physics.
At eighteen, she enrolled at Murray State University in agricultural engineering.
Harlan complained about tuition.
June reminded him he had once spent more on a used tobacco transplanter.
“That machine made money.”
“So will she.”
Della interrupted.
“I’m sitting right here.”
Opal was eighty-eight by then.
She no longer read at the kitchen table for hours.
Her eyes tired quickly.
Della read to her instead.
The old pamphlets remained stacked in the cabinet.
One evening before Della left for college, Opal asked:
“You taking any?”
“Pamphlets?”
“Yes.”
“They’re ancient.”
“So am I.”
Della smiled.
She chose three.
Gravity water systems.
Soil moisture management.
Small-farm irrigation.
Opal watched.
“Your grandfather liked that one.”
Della held it.
“Did he ever build anything from it?”
“No.”
“Then why keep it?”
Opal shrugged.
“Maybe he was keeping it for you.”
Della knew that was sentimental nonsense.
She loved it anyway.
