The roar of forty thousand miners’ inches of mountain snowmelt entering the covered stone channel of Saint Eleanor was the sound of life returning to an empire.
Inside the enclosed limestone channel—six feet wide and eight feet tall, lined with Roman volcanic cement high-pressure cement that had hardened eighty years before—the water didn’t merely flow. It raced forward with the focused, unswerving driving force of a royal army. Engineered at a perfect, unchanging slope of one foot in five hundred, the water moved at twelve feet per second, crowned with sparkling white foam and throwing up a cold, crystal-clear vapor that filled the air-flow chimneys along the mountain ridge.
Tomas Reed stood upon the upper check gallery at Mile Ten. He watched the aqueous surge cross the first alpine drain tube.
Beside him, Nessa Vale held her brass sound horn against the stone low roof wall, her eyes fixed on the sweeping landscape below. Her fingers felt the deep, rhythmic pulse of the water shaking through eighty thousand tons of dressed freestone.
“Speed is eight point four miles an hour,” Nessa said, her voice clear and measured above the rush of the stream. “Depth in the water chute is four feet six inches—full working capacity. The royal slope is holding to the line. No bubbling blast at the drain tube bends.”
