Science and research. Mineral prospecting. A ground comparator will reveal the presence of an ore body under the surface of the earth by measuring the total intensity and the plane of polarization of the secondary electro-magnetic field set up by the ore body. These students are using an adjustable coil of copper wire which acts as an electrical transformer, and may be tilted to determine the minimum and maximum intensity of the field. They are conducting an experiment in electronics, taught in the department of geophysics at a famous mining engineering school. They will apply the knowledge they are acquiring to airplane detection and anti-submarine warfare. Colorado School of Mines, Golden, Colorado

Science and research. Mineral prospecting. Electrical prospecting for metallic minerals may be carried on by using the dual coil radiometer to measure the electro-magnetic field of the earth, as it may be influenced by the presence of an ore body. Students training for war jobs in the minerals industry, or for service with the armed forces, are shown hunting for ore. A student at the left operates the field generator. The coils about the middles of the two others are made up of many strands of copper wire which act as transformers. The student second from right watches the level on his stationary coil to measure the electro-magnetic field. After completion of training, many students will be given commissions in naval ordnance, where they will use electronics for airplane detection. Colorado School of Mines, Golden, Colorado

Science and research. Mineral prospecting. Intensity of the earth's magnetic field, something a mining engineer needs to know if he is looking for vital metals under the crust of the earth, may be measured by the horizontal magnetometer and the vertical magnetometer shown here. Three engineering students employ geophysical methods, which they will use after they complete their training courses, for war jobs in the minerals industry or commission in the armed forces. Their knowledge will be applied to airplane detection and anti-submarine warfare. Most of the students are now in the enlisted reserve. Colorado School of Mines, Golden, Colorado

Science and research. Mineral prospecting. Speed in metallurgical analysis, to match the rapidity with which the nation arms itself, is possible through use of the spectrograph, a marvelous new machine used for study of materials through measurements of the arc of light they emit when heated. The aluminum and magnesium industries, steel companies and foundries use it for quick study of metals. Mines use it for exploration. The spectrograph will yield an analysis of seven elements in fifteen minutes determination, which would require up to four hours by old chemical methods. Three students in defense training courses at a famous mining-engineering school listen as an instructor shows them how the machine operates. Golden, Colorado

Science and research. Mineral prospecting. Chemical prospecting for oil becomes more and more important as the war goes on the demand for oil increases. Petroleum engineers call chemical prospecting the first scientific approach to the detection of oil in the earth. The big glass condensers, with which these engineering students are working with a professor of geophysics are used in a soil analysis test. The percentage of wax left as residue at the end of the experiment indicates the nearness of petroleum to the site from which the soil sample was taken. Colorado School of Mines, Golden, Colorado

Science and research. Mineral prospecting. Micro-fossils can play an important role in locating the proper spot to drill an oil well. A magnificent history of the flow of ancient seas, of climate, of the rise and fall of empires of primitive forms of life is preserved in stone. Students in defense training courses at a famous mining-engineering school learn to decipher and piece together for an engineering conclusion the facts contained in micro-fossils found in crushed rock. Here they are at work in the micropalenontological laboratory with binocular microscope using special lamps for horizontal illumination. A professor of the geophysics department stands at the far end of the table. Colorado School of Mines, Golden, Colorado

CAPE CANAVERAL, Fla. – At Fire Station No. 2 near the Shuttle Landing Facility at NASA’s Kennedy Space Center in Florida, Fire Rescue Services personnel have deployed and extended the ladder on the aerial fire truck during training in order to be certified in the operation and use of the vehicle. The center’s Fire Rescue Services recently achieved Pro Board Certification in aerial fire truck operations. Pro Board Certification is a globally recognized certification that puts on multiple courses that all fire departments throughout the world recognize and use to train their personnel. The unique aerial truck contains a 100-foot extendable ladder with a bucket at the end of it that can be used for rescues from taller buildings or aircraft rescue firefighting.
