The great net of straight thoroughfares lying at right angles, east and west and north and south, over the shoulders of Nob Hill, the hill of palaces, must certainly be counted the best part of San Francisco. It is there that the millionaires are gathered together vying with each other in display. From thence, looking down over the business wards of the city, we can descry a building with a little belfry, and that is the Stock Exchange, the heart of San Francisco: a great pump we might call it, continually pumping up the savings of the lower quarters into the pockets of the millionaires upon the hill. But these same thoroughfares that enjoy for awhile so elegant a destiny have their lines prolonged into more unpleasant places. Some meet their fate in the sands; some must take a cruise in the ill-famed China quarters; some run into the sea; some perish unwept among pigsties and rubbish-heaps.
