SATURDAY. MARCH 15. 1958 Mist'Mcrtched Pair Marshes' Army Surplus Tent May Help Drivers in a Fog By BONNIE JONES The fog, according to Carl Sandburg, comes in on little cat feet, but the Marshes’ fog lives in an army surplus tent in their back yard. What good is a fentfull of fog? VVeIL engineering, and his wife Elizabeth, have fog that blinds drivers and causes many Eastern turnpike authorities asked them to find out what kind of - car lights and street lights ■would best pierce the fog. Using family teamwork they set up a testing tent in the back yard. Tow heads John. 13, Rog er 12, and Ben 8 and pony - tailed Ann 10. shinnied up the poles to paint the top. while Mom and Dad built a floor length one third size mock-up of a highway, of masonite and covered it with asphalt. The road is complete with diagonal lines, overhead lights and speed limit signs. . The only vehicle on the fog bound road is a simulated rear of a truck that moves back and forth on Ann’s roller skates. An observer can put himself in the driver’s seat by looking into the tent through a glass window r similar to a car windshield in front of which are lights like those on a car bumper. To find out how much various types of lighting affect 'vision. Mrs. Marsh 'photographs the wispy fog. "I used to have Irou, ble getting pictures printed be fore I started developing them myself," she grinned. "They'd tell me that they'd tried and tried but just couldn't get the shadowy mist out of the pic tures." To make artificial fog, the Marshes hook up an air compres sor, the kind that inflates tires, to a garden hose. The. air jets blow across a stream of water and split it into fog particles that fill the tent in three minutes. More water can be added to create a denser fog. The Marshes’ fog exactly dupli cates natural fogs and what’s indie, inside the tent a light beam and photo cell can turn the ma chine on or off to keep the fog constant "The lights on cars and high ways today, although efficient in clear weather, produce near ly the worst possible light in foggy weather," Marsh said. ITs like this he gestured, "ordi nary street lamps light up the fog," which in turn scatters the light "so that the driver faces a ViTilliaTit white cloud." Standard headlights, mounted slightly below eyelevel, “force the driver to look down the light beam into a blinding hot spot of light.” Thus with ordinary light ing much of the light smacks the driver in the face and blinds him so he can’t see the road and can discern other cars only faintly. . The Marshes have devised a system they feel best improves vision in fog. It consists of 300 watt lamp ' spotlights hanging overhead at ’ 15-foot intervals. These send a narrow beam downward on the - road at right angles to the flow of traffic. "This system lights . up the road and not the driver," .Marsh says. State troopers usually do a when they first see the Marsh car. Resembling a gog gle-eyed monster it usually sportsl from six to eight headlights and! lour, foglights which makes it; very handy for chasing up and down foggy hills. "Ordinary headlights should he turned off when you use fog lights," Marsh advised. "We j found the most successful fog 1 headlights should be mounted ! 'low beneath the bumper if pos- j sible." Although these can get : knocked off," he' said, proper J styling could make them re ’ tract able. ■ More practical, he said is a' dear-lensed powerful spotlight at! about bumper height equipped; with polarized light filter that: filters out a part of the light andj a" polarized windshield filter that rejects all light from fog particles. Another highway light the mist-matched pair have de veloped is a 8-foot panel of 200 watt flourescent lights mounted low on the shoulder of file road or on. file middle strip of a divided highway.

Terms 'Mono 'Students Plague 1 Mononucleosis, a virus disease commonly known as “mono,” could well be termed “the college students’ plague." The disease is extremely common among those between the ages of 18 and 24, said Dr. Herbert R. Glenn, director of the University Health Center. In fact, it’s the most common disease of that age group, he said. Mono was first noted by doctors about 1525 in infants and small children. Since then it has shown a tendency to be more ore valent in late adolescence and early adulthood Glenn said physicians do not know how lhe disease is trans mitted. But he said the most likely means is by direct con tact—by kissing and from eat ing utensils, for example. "I don't subscribe to the theory thnt-mononucleosis is brought on I by overwork and not enough' deep," Glenn said. He said this common misconception probably arose because victims of the dis-' ease may ‘'feel awful” for weeks before they actually get a fever. 1 Glenn also said the number of. cases among University students' varies greatly from month to* month and from year to year. “Last year we had very few cases; this year we’ve had a great many.; I don’t have any explanation for! that at all.” Mono is a virus diseasa affect ing the lymphatic system (the tonsils, adenoids, and glands.) Early symptoms are tonsilitis and a swelling of the glands throughout the body. Then comes a period of fever, which generally lasts five to seven days, but occasionally as long as three weeks, Glenn said. Diagnosis of mononucleosis is confirmed by laboratory blood: tests, and evidence that the virus is still present often can be found for several weeks after apparent recovery Glenn said there is no specific | treatment for the disease. "An- i li-biotics should hot be given.” I he said. "They don’t help." Af- I ter the victim recovers from the fever stage he should get lots of rest and should eat a large amount of starchy foods for four to six weeks. Glenn said. He summed up mono’s progress as “slow in coming, an acute per iod. and then slow in leaving." But. he said, most cases don’t re cur after recovery is complete. “When vou’ve had it once, you’ve had it,” he said. Service Tests Will Be Given !
