"Who's Who in America" is long on the arts and on learning and comparatively weak in business and the professions. Now some one who has taken the trouble has found that more persons mentioned in "Who's Who" by the thousand of the population were born in Massachusetts, than in any other state; but that Massachusetts is crowded closely by California, with the rest nowhere. The institutions of learning in Massachusetts account for her pre-eminence; the art spirit does it for California. The really big men nurtured on California influence are few, perhaps; but she has sent out an amazing number of good workers in painting, in authorship, in music and especially in acting. "High society" in San Francisco had settled down from the rather wild spirit of the middle period; it had come to be there a good deal as it is elsewhere. There was much wealth; and the hills of the western addition were growing up with fine mansions. Outside of the city, at Burlingame, there was a fine country club centering a region of country estates which stretched out to Menlo Park. This club had a good polo team, which played every year with teams of Englishmen from southern California and even with teams from Honolulu. The foreign quarters are worth an article in themselves. Chief of these was, of course, Chinatown, of which every one has heard who ever heard of San Francisco. A district six blocks long and two blocks wide, housed 30,000 Chinese when the quarter was full. The dwellings were old business blocks of the early days; but the Chinese had added to them, had rebuilt them, had run out their own balconies and entrances, and had given the quarter that feeling of huddled irregularity which makes all Chinese built dwellings fall naturally into pictures. Not only this; they had burrowed to a depth of a story or two under the ground, and through this ran passages in which the Chinese transacted their dark and devious affairs--as the smuggling of opium, the traffic in slave girls and the settlement of their difficulties. In the last five years there was less of this underground life than formerly, for the Board of Health had a cleanup some time ago; but it was still possible to go from one end of Chinatown to the other through secret underground passages. The tourist, who always included Chinatown in his itinerary, saw little of the real quarter. The guides gave him a show by actors hired for his benefit. In reality the place amounted to a great deal in a financial way. There were clothing and cigar factories of importance, and much of the Pacific rice, tea and silk importing was in the hands of the merchants, who numbered several millionaires. Mainly, however, it was a Tenderloin for the house servants of the city--for the San Francisco Chinaman was seldom a laundryman; he was too much in demand at fancy prices as a servant.
