Dr. R. A. Millikan, American scientist, has recently completed a lecture tour of the Australian states on the general theme Science at the Service of Humanity. The motives of men, their mode of life and their outlook were much the same, he says, when his grandfather in 1825 loaded in a covered wagon his young wife and all his worldly goods and trekked west from Massachusetts to the banks of the Rock River in western Illinois as when, 4,000 years before, Abraham trekked west from Ur, of the Chaldees.
