He walked the field on a dry afternoon in October, following the grade of the main collector toward the corner where it had to exit. He carried the copied diagram and a spade and the transit, which he had cleaned enough to trust for a rough reading. He was looking for the outfall, a clay tile set flush into a low bank somewhere along the field boundary, open to daylight, draining into the ditch below. Elias would have ended it in daylight. A system built to a recorded grade did not end in a hole. It ended where a man could see it run.
The field ended at the county road. The county road sat four feet higher than it had in 1896. James had known the road was built up. Everybody knew the road was built up. The improvement had been made in 1961, when the county regraded the road surface and raised the embankment to straighten the approach into the bridge. He had watched them do it when he was fifteen years old, standing at the fence line while the graders worked, understanding nothing about what was under the ground they were burying. He remembered the dust, and the way the operator had waved him back, and his father saying the county was finally going to fix the bad approach. He did not remember anyone walking the ditch with a deed. He did not remember anyone asking what the low corner drained to. The outfall tile was under the road embankment. The drainage system Elias Harker had built from 1893 to 1896 had been fully functional in 1961, without anyone looking at the deed, or the soil survey, or asking what was in the ground. The county had sealed its exit under four feet of compacted fill. For forty years, the tile had been working exactly as designed. There was nowhere for the water to go.
That was the part that sat in him on the walk back to the house. Not malice. Not even carelessness of the personal kind. A road crew with a grade to meet, a schedule, a bad approach to straighten before winter. A boy at a fence. A father glad the county had come. And under the fill, a clay mouth still pointed at the ditch it could no longer reach. Every spring after that, the northwest section had done what a closed system does. It had held. The three contractors had laid new plastic above a grid that was already full, and the new plastic had found the same dead end, or had never been tied to the old main at all, and had spent its short effectiveness on the water it could reach before the old system, still intact and still blocked, took the rest and kept it. James had been fighting the symptom in the top two feet. The cause was four feet of county fill and a record nobody had opened.
He dug along the edge of the embankment the next week, after he had called the county engineer and told him, plainly, that he was going to open a drain that their road had buried. The engineer was not hostile. He asked James to stay off the driving surface and to sleeve anything that went through the toe of the fill. James agreed. He found the outfall tile on the second afternoon, a little left of where the diagram put it, which meant the diagram was honest and his pacing was not. Still intact. Still at grade. Still pointed in the right direction. The mouth was packed with the fine gray fill of the embankment, not with a century of field silt. He cleaned it back to clean clay. He could see the collar of the next tile. He could see the fall.
