One dry morning the village well gave nothing but dust. The rope came up light, the bucket came up empty, and by noon the whole village stood around the stone rim in silence. The well had never run dry in living memory.
Ada, the young well-keeper, did not panic and she did not guess. Before she fixed anything, she set out to learn why the water had gone — because a problem you don't understand is a problem you can't solve.
She walked, watched and counted for three days, and she found three causes. First, the village had grown: twelve new households now drew from a well built for half that number. Second, she climbed to the spring that fed it and found the channel choked — a slab of fallen rock had blocked the flow at its source. Third, no one had saved a single drop in the wet season; when the rains came, the water simply ran away downhill.
So Ada answered each cause in turn. She set a fair ration, so the crowd of new households drew only what the well could give. She gathered the strongest villagers and together they cleared the fallen rock, and the spring ran free again. And she led them in digging a rain-catch reservoir, so the next wet season would be stored, not wasted.
By the following spring the bucket came up heavy. The well flowed once more — because every cause had met its cure.
