South of the Slot by Jack London — Read

OLD San Francisco, which is the San Francisco of only the other day, the day before the Earthquake, was divided midway by the Slot. The Slot was an iron crack that ran along the centre of Market Street, and from the Slot arose the burr of the ceaseless, endless cable that was hitched at will to the cars it dragged up and down. In truth, there were two slots, but in the quick grammar of the West time was saved by calling them, and much more that they stood for, "The Slot. " North of the Slot were the theatres, hotels, and shopping district, the banks and the staid, respectable business houses. South of the Slot were the factories, slums, laundries, machine-shops, boiler works, and the abodes of the working class.

The Slot was the metaphor that expressed the class cleavage of Society, and no man crossed this metaphor, back and forth, more successfully than Freddie Drummond. He made a practice of living in both worlds, and in both worlds he lived signally well. Freddie Drummond was a professor in the Sociology Department of the University of California, and it was as a professor of sociology that he first crossed over the Slot, lived for six mouths in the great labour-ghetto, and wrote _The Unskilled Labourer_-a book that was hailed everywhere as an able contribution to the literature of progress, and as a splendid reply to the literature of discontent. Politically and economically it was nothing if not orthodox. Presidents of great railway systems bought whole editions of it to give to their employees. The Manufacturers' Association alone distributed fifty thousand copies of it. In a way, it was almost as immoral as the far-famed and notorious _Message to Garcia_, while in its pernicious preachment of thrift and content it ran _Mr. Wiggs of the Cabbage Patch_ a close second.
