AGE OF THE EARTH.
Professor Frank Allen, of Manitoba University, stated, in a lecture at Winnipeg on. "The Age of the Earth," that radium had upset all the theories on this subject. Lord Kelvin, 7 ' he said, "who computed that the earth was twenty million years old, declared that unless some now way of producing heat in the earth's .surface could be found, his calculations were correct. Such a new way has actually been discovered in radium, which has the power of giving out heat without diminishing in weight. One pound of radium would keep a house warm for 2000 years. Radium is scattered throughout the earth's surface, and therefore Lord Kelvin's calculations are worthless. Radium gives off helium,, and helium is scattered.throughout the. earth's crust. .The amount of helium given off by ah "actual piecei 'of rock could easily be measured. By comparing, the amount of radium and of helium in a piece of rock it would be possible to form an estimate of the earth's age, and if this were done it would he found that the earth was over 1,500,000,000 years old."
