...Bennett left as he came, a very close personal friend of mine. We parted closer friends, if possible, than ever...
...ideas led him to attempt expression of baffling concepts. He died last June at Avignon, France, of peritonitis following an appendectomy which a War-time injury had made risky. While a lieutenant in the British Army, he and 15 companions were buried alive in a trench after a mine explosion. His companions died, he was unconscious for several weeks, hospitalized for a year. His play is in many ways characteristic of his life: tragic, bursting with inarticulated thought. The scene is laid in post-War Germany. A revolutionary group upsets the oldtime government of a little town. There...
Cause of the explosion was undetermined last week. The mine interior previously had been thought to be so damp it could not contain gas, and open torches were permitted the miners. Authorities last week guessed the explosion occurred when a coal slide caused sparks, which ignited gas gathered in a pocket. Such explosions in coalmines occur instantaneously. Therefore, and because coalmines are not equipped with compressed-air systems as are metal mines, "stench" warnings as recommended last week by the U S. Bureau of Mines (see p. 62) are not practicable for coalmines...
Last week while mine inspectors were investigating the coal mine tragedy in Millfield, Ohio (see p. 18), Daniel Harrington, Chief of the Safety Division of the U. S. Bureau of Mines, urged metal mine operators to adopt a modern method of warning miners of danger. The alarm signal is a penetrating odor. Metal mines (unlike coal mines, which use electrically operated fans) are ventilated by compressed air which travels into the farthest corners at the rate of about 1,000 ft. per sec. Engineers have found that a little odorous liquid injected at the source of the air supply will...
Experimental work was carried on in 1918 by the Bureau of Mines at Granite Mountain Shaft, Butte, Mont., where 13 years ago 162 men lost their lives in a fire because warning was not spread quickly enough. At first pleasant odors were used but were not successful. Workmen did not run when they .sniffed violets or roses. But when experimenters released butyl mercaptan which smells like garlic, miners dropped their tools at once, raced for the exit. The stench safety method has been adopted by the American Standards Association which suggests to mine operators how best to conserve their employes...
