ON May 9, in a town in southern California, Mr. Post, of cereal coffee fame, shot and killed himself. His fortune is estimated as high as a hundred million dollars. Twenty years ago Mr. Post was a poor man, and an invalid as well. He visited a sanitarium where cereal coffee was manufactured and used. He conceived the idea of commercializing this, and the result was that in these few brief years he bounded from a poor man to a multimillionaire. The next day after Mr. Post's suicide, Col. John C. C. Mayo, of Kentucky, died in a hotel in New York City. He left a fortune of twenty millions. Twenty-five years ago Mr. Mayo was a schoolteacher struggling with poverty in the eastern Kentucky mountains. These are among the illustrations that are constantly occurring which show the vast amount of wealth that one man may heap together in these times within the limits of a small portion of his natural life. And these vast fortunes, no matter how much we may excuse them, are the occasion for the great rumblings of discontent that are threatening to visit the whole world with a mighty upheaval.
