AGE OF THE EARTH.
Professor Frank Allen, of Manitoba Pniversity, slated in a lecture nt Winnipeg on "The Ago of the Earth," that radium had upset nil the theories on this subject. "lord Kelvin," ho said, "who computed that the earth was twenty million years old, declared that unless some new 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 mrm for 2000 years. Radilim is scattered throughout the earth's surface, nmi, therefore Lord "Kelvin's calculations are worthless, linilhim gives olf helium, and helium is scattered throughout the earth's crust. The n mount of helium given olf by nn actual piece of rock could easily bo measured. By comparing tho amount of radium and of helium in a piece of rock it would be possiblo to form an estimate of the earth's ngo, anil if this were dono it would t>e found that tho earth was over I 1,500,000,000 years old."
