AS SAO PAULO GROWS SUNLIGHT AND SHADOWS TURN THE WORLD UPSIDE DOWN IN A SAO PAULO POOL Black swans from "down under" in Australia float gracefully among the lilies before the new museum of the State Forestry Department. Their reflections point toward their native land on the other side of the globe. The Tropic of Capricorn crosses the city's suburbs beyond the museum. A golf course lies across this imaginary line and players often drive their balls across it from the Temperate into the Torrid Zone.
