Water.
Enough water could mean no emergency cattle sale.
No trucking.
No desperate feed-and-water decision before winter.
Walter immediately said:
“Don't start counting cows yet.”
Helen looked at him.
“I’m not.”
“Yes, you are.”
“I am counting everything.”
“That is my job now.”
The sentence quieted the room.
Daniel’s absence was rarely spoken directly.
It entered conversations as responsibility.
As extra work.
As the empty chair.
Toby looked down at the notebook.
He knew his mother was frightened.
He also knew she would hate him saying it.
So he said:
“I’ll keep measuring.”
Helen nodded.
“Do that.”
The next several days turned Toby’s curiosity into routine.
Morning marker.
Evening marker.
Temperature by the kitchen thermometer.
Wind.
Cloud.
Any rainfall.
Waterline.
He recorded cattle behavior.
Whether they entered from north or east.
How much mud formed.
The notebook became unexpectedly useful.
By September 6, the pond had risen enough to cover part of the exposed shelf near the deepest basin.
Not much.
But measurable.
At the rope, the wet patch widened.
Walter’s memory sharpened.
He remembered a small wooden structure set lower than the surrounding ground.
Stone foundation.
Tin roof.
His mother’s milk cans standing in cold water.
He remembered a wooden walkway.
And something metal.
“What metal?”
Toby asked.
“Handle, maybe.”
“Gate?”
Walter shook his head.
“Could be.”
“I remember being told not to touch it.”
That caught Toby’s attention.
“Why?”
“Because I was a child.”
“That explanation covers a lot.”
Walter smiled.
“More than you think.”
Then he remembered a pipe.
Not clearly.
Just that water left the springhouse somewhere.
“Where?”
“Downhill.”
“Toward lower pasture.”
“Why would they send water away?”
“Because a spring never asks whether you need more.”
Walter said.
“If it runs, it runs.”
That sentence sat with Toby.
Helen finally said:
“We need somebody who knows ponds.”
Walter agreed.
But before making that call, he wanted to search old farm records.
The Mercer attic occupied half the second floor over the original portion of the house.
It was hot, dusty, and packed with four generations of things nobody had been willing to throw away.
Seed catalogs.
Tax receipts.
Veterinary books.
Farm journals.
A broken radio.
Three boxes of Mason jars.
Daniel’s high-school football helmet.
Toby climbed first.
Walter followed more slowly.
They spent nearly two hours finding nothing useful.
Then Toby opened a narrow ledger bound in cracked brown cloth.
The first pages contained feed purchases from 1928.
Corn.
Salt.
Fence staples.
Kerosene.
Then planting notes.
Then sketches.
Toby almost missed the page because the pencil had faded.
At the top:
LOW SPRING.
Below it, a rough drawing.
Property not to scale.
A small square.
A line.
Another square.
Words in handwriting so faint Walter needed his glasses.
“Spring house.”
Walter whispered.
Toby felt his chest tighten.
The page showed a spring emerging in the hollow.
Water entered a stone-lined collection box.
From there, one branch appeared to feed the springhouse.
Another line traveled downhill.
Beside that line:
