To a few men, young engineers whose passion had been fired by a dramatic facet of their profession—the construction of highways—the Belmont Mansion was Delphi. They came to it to learn, not just the engineering of great roads, for they could learn engineering elsewhere, but rather a secret available at that time nowhere else: the secret of how to get great roads built. For them, the big table at which Moses sat was an altar on which they laid their dreams in the hope of learning the alchemy by which the dreams might be transmuted into concrete and asphalt and steel.
