FLYING IN FROM THE NORTHWEST, 21,000 FEET ABOVE THE PACIFIC, SAN FRANCISCO ISGRAPHICALLY REVEALED Hundreds of square miles of land and water, various cities, islands, mountains, and valleys unfold herebefore the powerful eye ofthe high-altitude camera. About 1,750,ooo people inhabit the area shown. Far below, unseen, fleets of boats plow the bay andocean. From here 18coast lines operate; 20 lines run via Panama to the Atlantic seaboard; 55 lines operate to foreign ports-17 to Europe, 13 to Central and South America, 13totrans-Pacific ports, 6 to Australasia, I to Africa, and 5 around the world. Yet, till that August day in 1775 when Lieutenant Ayala entered the Golden Gate with the San Carlos,no white man's craft had faced its tides.
