Page 16 - France I was sent to the British front to investigate military mining. When I was presented to Brig. Gen. RN Harvey, who commanded the British mining troops, and stated my mission, he said, without knowing my profession: 'The first requisite for success in military mining is to secure the services of experienced geologists. I wish I had known that at the start.
Page 16 - ... of the authorities in its efficacy. In our Army many large plants, such as hospitals and flying fields,, were located without any definite knowledge of the source of needed water. In the British Army, after the first year, no well drilling was permitted without the approval of the geologist in charge of water-resource investigations. There was no such rule in the American Expeditionary Force, and many wells were drilled with no adequate knowledge of the underground-water conditions. In many instances...
Page 16 - German troops in the St. Mihiel sector were giving official recognition to the use of the witch-hazel stick in locating sources of underground water. The first duty of the geologist detailed to this sector was to collect data on the results achieved by this implement, so as to shake the confidence of the authorities in its efficacy. In our Army many large plants, such as hospitals and flying fields, were located without any definite knowledge of the source of needed water. In the British Army, after...
Page 16 - During the great battle of Verdun a body of troops was ordered to intrench itself on the high plateau of the Cotes de Meuse. Even a casual examination of the geologic map would have shown that the plateau was underlain by hard limestone with less than a foot of soil. This material could not be excavated with the light tools furnished or even with proper equipment in the time available. As a consequence there was a large and needless loss of life. In part of the Lorraine sector the front-line dugouts...
Page 16 - In the early part of the war neither the British nor Germans recognized the need of geologic knowledge as a preparation for military mining. The success of the British in gaining control of the underground situation must in large measure be credited to the refinement of the geologic studies and their interpretations made by Lieut. Col. T. Edgeworth David.
Page 165 - The surface of the Interior Lowland along the foot of the escarpment and for some 30 miles or more to the westward is a rolling irregular upland at an altitude of 1,000 feet, more or less, dissected by streams to a depth of 200 feet or more. It is at essentially the same altitude and of much the same character as the Lexington...

Japan is covered with snow for two or three months in winter, the fall being heavier on the Japan Sea coast than on the Pacific coast. In the S. parts of the country, however, snow-storms are rare, and when snow falls it seldom lies on the ground for more than a day or two. The following table shows the average temperatures of the different seasons in some of the principal cities and tourist resorts: • '' •'...

Page 17 - Geology finds its principal application to war in forecasting the physical conditions that will be encountered in the execution of certain military projects, such as the construction of fortifications, the maneuvering of troops, and the erection of engineering structures, and in determining the sources of water, road metal, and other mineral supplies. "The...
Page 17 - I had known that at the start.' lications contained many articles advocating the use of geologists in the army and pointing out the various applications of the science to war problems. This propaganda was finally stopped by the censor under the plea that military secrets were being published.
