The streets lie straight up and down the hills, and straight across at right angles, these in sun, those in shadow, a trenchant pattern of gloom and glare; and what with the crisp illumination, the sea-air singing in your ears, the chill and glitter, the changing aspects both of things and people, the fresh sights at every corner of your walk--sights of the bay, of Tamalpais, of steep, descending streets, of the outspread city--whiffs of alien speech, sailors singing on shipboard, Chinese coolies toiling on the shore, crowds brawling all day in the street before the Stock Exchange--one brief impression follows and obliterates another, and the city leaves upon the mind no general and stable picture, but a profusion of airy and incongruous images, of the sea and shore, the east and west, the summer and the winter. In the better parts of the most interesting city there is apt to be a touch of the commonplace. It is in the slums and suburbs that the city dilettante finds his game. And there is nothing more characteristic and original than the outlying quarters of San Francisco. The Chinese district is the most famous; but it is far from the only truffle in the pie. There is many another dingy corner, many a young antiquity, many a _terrain vague_ with that stamp of quaintness that the city lover seeks and dwells on; and the indefinite prolongation of its streets, up hill and down dale, makes San Francisco a place apart. The same street in its career visits and unites so many different classes of society, here echoing with drays, there lying decorously silent between the mansions of Bonanza millionaires, to founder at last among the drifting sands beside Lone Mountain cemetery, or die out among the sheds and lumber of the north. Thus you may be struck with a spot, set it down for the most romantic of the city, and, glancing at the name-plate, find it is in the same street that you yourself inhabit in another quarter of the town. 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 pig-sties and rubbish-heaps.
