The late Peter Marshall was an eloquent speaker and for several years served as the chaplain of the US Senate. He used to love to tell the story of the "Keeper of the Spring," a quiet forest dweller who lived high above an Austrian village along the eastern slope of the Alps.
The old gentleman had been hired many years earlier by a young town councilman to clear away the debris from the pools of water up in the mountain crevices that fed the lovely spring flowing through their town. With faithful, silent regularity, he patrolled the hills, removed the leaves and branches, and wiped away the silt that would otherwise have choked and contaminated the fresh flow of water.
