...grind through the rock with drills. All day the air is filled with minute particles of stone, deadly dangerous dust is sucked into human lungs with every breath. The dust varies according to the stone, but wherever there is quartz, flint, ganister, sandstone, granite, there silica particles lead all the rest. These tiny glasslike fragments do not dissolve in the moisture of the nasal passages. Sharp-edged, insoluble, they penetrate the lungs, enter the cells. The crowded cells clump together. In an effort to protect the body, fibres begin to grow around the "clumps." Gradually the lungs choke up with...
...rain. The new light in Virginia is five times as large and bright as this biggest and brightest light in Illinois. When 17,200 watts of current are turned on, the crater of the new light's arc becomes the hottest spot on earth-38,000° Fahrenheit. Quartz prisms in the 62-inch globe absorb so much of this heat that the light, passing off with an intensity of 1,385,000,000 candle power,* will not blister the skin of persons keeping more than 1,000 feet distant. Engineers predicted that on clear nights the Monticello beam...
...Franklin Smith, 96, perhaps richest New Englander ($50,000,000), who built the world's second largest stockyard in Omaha, Neb.; in Boston. With his three brothers he started his career by buying a gold mine near Pike's Peak, Col., which was thought to be a quartz claim. General Fitz-John Porter† attempted to bore into the claim. Gold-miner Smith forthwith made an opening into the outlaw shaft from below, built a fire, and smoked out the General's workers. The General promptly installed a huge fan which blew the smoke down into...
Last week the scientific world heard of a noise that was literally "killing." Inaudible to human ears, it consisted of extremely short, rapid sound waves produced from electrically driven quartz crystals. Similar waves had been used in submarine detection, during the War, when it was noticed that fish in the experimental tanks were occasionally killed. Subsequent experiment had shown that stagnant water could be freed from microorganisms; that small fish died in convulsions after "hearing" the quartz waves; that the blood count of a swimming mouse was reduced one half after 20 minutes' exposure. Possible significance: swift purification...
...glass used in Birmingham was "Vitaglass," a true glass of high quartz content invented by one F. E. Lamplough, M. A., Cambridge University, made in a factory in Birmingham...
