...South African teeth, Dr. Gregory also found connections with Peking Man, the orangutan, and Sivapithecus, a manlike fossil ape discovered many years ago in India. The geological character of the ground, however, indicated that Dr. Broom's creatures lived relatively late in the Glacial Age, by which time definitely human types such as Peking Man, Piltdown Man and Heidelberg Man had already appeared. Plesianthropus and Paranthropus thus appeared as laggard survivors of a much earlier evolutionary spurt-"conservative cousins of man," says Dr. Gregory, "and progressive cousins of the modern apes...
Before a capacity audience of over 300 at the Institute of Geographical Exploration, Bradford Washburn '33, veteran of eight Alasken expeditions, described his adventures of last June and July when he surveyed 1500 square miles of unexplored glacial territories...
Later in the summer Washburn's expedition discovered what is believed to be the world's largest ice field outside the polar regions. In extensive flights around Mount Logan and Mount Saint Elias, Washburn proved the existence of a tremendous glacial system 255 miles long...
This district is particularly interesting to the geographer as it is an ice bowl, the greatest area of glacial ice known outside the Polar regions. Many of Alaska's most famous glaciers are mere outlet trickles from this-survivor of the Pleistocene...
Under the coarse glacial bed of Manhattan's murky East River, sand hogs for the last year have been boring the two tubes of a midtown vehicular tunnel intended by 1940 to connect Manhattan Island with Long Island. Each 31 feet in diameter, the tubes are bored by great circular "shields." Like the mouth of a great pipe, the shield is forced ahead by hydraulic pressure, cutting two feet eight inches at each thrust into sub-bottom deposit. Between forward thrusts, workmen remove the muck within the shield, line each new section with cylindrical cast-iron casing. Keeping...
