In 1848, the population of San Francisco was eight hundred; three years later, thirty-five thousand people lived there. In 1853, the population went past fifty thousand and San Francisco became one of the twenty largest cities in the United States. By 1869, San Francisco possessed one of the busiest ports in the world, a huge fishing fleet, and the western terminus of the transcontinental railroad. It teemed with mansions, restaurants, hotels, theaters, and whorehouses. In finance it was the rival of New York, in culture the rival of Boston; in spirit it had no competitor.
