Beyond this point on the river Cambridge became a kind of miniature Venice, its river water lapping up against the ancient stone of college walls, here mottled and reddened brick, there white stone. Stained, lichened, softened by water light. Here the river became a great north-south tunnel, a gothic castle from the river, flanked by locked iron gates, steps leading nowhere, labyrinths, trapdoors, landing stages where barges had unloaded their freight: crates of fine wines, flour, oats, candles, fine meats carried into the damp darkness of college cellars.
