...such depths, or deeper, Dr. Shapley would have his plutonic laboratories. Ph. D. moles would record the pulsations of the earth's crust which, according to one theory, is as rigid as steel and as elas- tic, rather than viscous, like stiff pitch. They would verify the hypothesized drift of North America from Europe and South America from Africa. (As can be seen on a globe, the continents would roughly fit together.) Such scientific gnomes might be able to determine the existence of an interstellar ether. They could certainly measure the relation of earth heat to earth depth. They...
Genesis of Continents. Earth has a rind 2,000 miles thick, a core 4,000 miles in diameter. The core is a hot, viscous liquid, composed chiefly of iron and held within the mighty pressure of the rind. At times the central heat melts spots in the rind; asthenoliths or blisters result 30 to 600 miles below Earth's surface. The asthenoliths may be hundreds of miles wide, 10 to 20 miles thick. So theorized Leland Stanford's Bailey Willis...
...important than other fuel-substitute discoveries lately made- coal dust in the U. S. and Germany, fagots in France (Time, Oct. 11). Submitting oxygen, hydrogen and coal to a pressure of 200 atmospheres, introducing a secret catalytic agent and filtering the result, M. Audibert had indubitably obtained a heavy viscous fluid which readily refined to kerosene, gasoline and the usual by-products of that "black gold" which nature only makes after centuries of compression upon organic matter in subterranean strata...
...matters in motion with a resume of the modern description of Earth's age and structure. Age?"definitely between one and 10 billion years" as estimated by timing the decomposition of uranium and other radioactive elements. Structure?a hades-hot metallic core, rigid as steel; then an envelope of viscous material, kept fluid by enormous pressure, not heat conducting, having faint tides, upon which the earth's ,crust "floats". The elasticity of the envelope which is 60 miles beneath the crust, and the core's rigidity, had been deduced from studying waves of force in earthquake shocks...
