There is very little known of Eli Whitney, inventor of the cotton gin. But Burlingame has made the most of the available facts; and reveals, in a fictionized biography, a genius in mechanics, a man ahead of his times. He traces his early revolt from the law and teaching; he tells of his inventions and the furor they created in labor and economic circles. He shows Whitney losing contact with human beings as he is wedded to his machine and his vision of a mechanical world. Good biography which other boys should enjoy.
