vaquero, go hustling by; at the sunny end of the street, a thoroughfare roars with European traffic; and meanwhile, high and clear, out breaks perhaps the San Francisco fire-alarm, and people pause to count the strokes, and in the stations of the double fire-service you know that the electric bells are ringing, the traps opening, and clapping to, and the engine, manned and harnessed, being whisked into the street, before the sound of the alarm has ceased to vibrate on your ear. Of all romantic places for a boy to loiter in, that Chinese quarter is the most romantic. There, on a half-holiday, three doors from home, he may visit an actual foreign land, foreign in people, language, things, and customs. The very barber of the Arabian Nights shall be at work before him, shaving heads; he shall see Aladdin playing on the streets; who knows but among those nameless vegetables the fruit of the nose-tree itself may be exposed for sale? And the interest is heightened with a chill of horror. Below, you hear, the cellars are alive with mystery; opium dens, where the smokers lie one above another, shelf above shelf, close-packed and grovelling in deadly stupor; the seats of unknown vices and cruelties, the prisons of unacknowledged slaves and the secret lazarettos of disease. With all this mass of nationalities, crime is common. There are rough quarters where it is dangerous o' nights; cellars of public entertainment which the wary pleasure-seeker chooses to avoid. Concealed weapons are unlawful, but the law is continually broken. One editor was shot dead while I was there; another walked the streets accompanied by a bravo, his guardian angel. I have been quietly eating a dish of oysters in a restaurant, where, not more than ten minutes after I had left, shots were exchanged and took effect; and one night about ten o'clock, I saw a man standing watchfully at a street-corner with a long Smith-and-Wesson glittering in his hand behind his back. Somebody had done something he should not, and was being looked for with a vengeance. It is odd, too, that the seat of the last vigilance committee I know of--a mediaeval _Vehmgericht_--was none other than the Palace Hotel, the world's greatest caravanserai, served by lifts and lit with electricity; where, in the great glazed court, a band nightly discourses music from a grove of palms. So do extremes meet in this city of contrasts: extremes of wealth and poverty, apathy and excitement, the conveniences of civilisation and the red justice of Judge Lynch.
