A Crazy Scientist Breaks Loose

Bryn Mawr, Pa., Feb. 24—The use of the Government surplus of smoke making material left over from the war in signaling Mars was suggested by James. G. Crenshaw, associate professor of chemistry at Bryn Mawr College, who served in the chemical warfare section of the American Expeditionary forces. Smoke screens hundreds of miles in width would be more like to be discovered. He contends that an area as large of the state of Pennsylvania should be used with black and white streaks of smoke to attract attention of the people on the planet.
