...Antarctic continent is a pie-shaped disk 5,000,000 sq. mi. in area, circled by a white crust of mountains 10,000 ft. high. It may contain valuable minerals or oil. Great Britain has a generally recognized claim to two segments of the pie. British Explorers James Clark Ross (1902), Robert Falcon Scott, (1902), Sir Ernest Henry Shackleton (1919) claimed their discoveries in the name of the British sovereign...
...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...
...stone that is thought to the billions of years older than the stones of the earth's crust, older, indeed, than the earth itself, and whose secrets are the same as the ultimate secrets of the origin and existence of the material universe, was exhibited last Wednesday night by Professor Harlow Shapley, director of the Harvard Astronomical Observatory, in the second of a series of five lectures in the new Commerce Hall Auditorium of the College of the city of New York...
...Geology, and tutor in the department of Geology, when queried about the quake last night, stated that he believed its point of origin to have been the Fundian Fault Zone, in the Gulf of Maine. At this point there is a very ancient fracture in the earth's crust, extending from the Bay of Fundy, Southwest, to the region of Cape Ann. That zone has caused so many earthquakes in the last three centuries that whenever one is felt near Boston, it is suspected as being the cause. The last tremor was felt about Boston on January 7, 1925. Professor...
...volcano of Santa Maria has jutted high in the backbone of the Sierra Madre, breathing acrid vapors against the blue Guatemalan sky. Never since the eruption of 1902 has it done much more than that. Planters grew used to the rumblings of Holy Mary, dug through the sterile crust of lava on her flanks to plant coffee bushes in the rich soil beneath. In recent years aviators have used the white plume from her crater as a beacon. Ten days ago Pilot D. G. Richardson, operations manager of the Mexican division of Pan American Airways, flying north on his regular...
