But she and about 20 other persons were evacuated Thursday night after the volcano erupted again, sending chunks of pumice onto houses in Cougar. Volcano spews molten debris over 7-m ie area One killed, five hurt in Ypsi GM accident YPSILANTI (UPI)-One worker was killed and five others injured yesterday in a construction accident at General Motors Corp.'s Willow Run assembly plant, GM officials said. The accident occurred as a construc- tion crew was pouring a concrete floor for a plant addition designed to in- crease material storage space at the facility, a GM spokesman said. "A BOOM BEING used in getting the concrete from the truck to the floor gave way, apparently," the spokesman said. Killed in the accident was Duane Beck of Saline, an employee of Emanuel Co., the Detroit-area contrac- ting firm building the plant addition, GM said. The injured, who were taken to St. Joseph's Hospital in Ann Arbor, in- cluded four other Emanuel Co. workers and a GM construction staff engineer, the spokesman said. THREE OF THE men-identified as construction workers Charles Cooper and Calvin Oliver, both of Ann Arbor, and Chuck Veal-were treated and released, a hospital spokeswoman said. Hospitalized in fair condition was Emanuel employee John Biachowski of Wyandotte. The GM engineer, Ervin Warnick, was hospitalized in good con- dition, the spokeswoman said. Authorities were investigating the cause of the accident, which shut down construction work 'for the day at the site, GM said. At one time, platinum was gold- plated to make counterfeit gold coins. It was almost impossible to detect the fraud by weight because the density of both metals is almost the same. FromAPand UPI Molten debris surged out of Mount St. Helens yesterday covering the volcano's slopes for seven miles with a 400-degree fahrenheit shroud of deadly rock, ash, and gas. Authorities evacuated about 400 per- sons living near the mountain. Another 1,000 Weyerhaeuser Co. employees working in the area also were evacuated. THE UNPREDICTABLE volcano pumped a plume of steam, ash, and marble-size pumice 10 miles high late Thursday night, giving some cities their worst dusting yet. ' Portland Mayor Connie McCready declared a limited state of emergency and imposed a 15-mph speed limit. The limit was lifted by mid-day after rain and city crews washed the ash from major downtown streets. The volcano's third major eruption in less than a month shot volcanic grit and pumice over 4,500 square miles of nor- thwestern Oregon and parts of south- western Washington. GEOLOGISTS EXPRESSED sur- prise at- the force of the blast, which dropped pebbles of pumice up to an inch in diameter on Cougar, 10 miles south- west of the mountain. "It was a major eruption," Pete Rowley, a U.S. Geological Survey geologist said yesterday. "It is silent for now, but it could do the same thing it did last night again." No injuries or deaths were reported from the latest eruption. The volcano's boiling crater remained obscured in clouds for about 15 hours after the Thursday night erup- tion. When the weather cleared enough for scientists in a helicopter to get a good look, Rowley said, the discovered that a pyroclastic flow - similar to the one that occurred when the mountain first exploded like an atomic bomb on May 18- had rolled out of a huge gap in the crater's northern side into the Spirit Lake and Coldwater Creek drainage areas. A SIMILAR deadly cover of heavy, burning ash may have killed as many as 70 people when the volcano first blew nearly four weeks ago. Once a green- forested area with the blue waters of Spirit Lake at its heart, the area is now a grey, ghostly zone where all the trees have been smashed like matchsticks by the volcano's force. It was not believed likely that anyone See SHROUD, Page 6 Researchers: More blacks suspended than whites (Continued from Page 3) So the teachers feel that any unpleasant incident has to be acted upon firmly to ensure these parents that their kids are safe," Moody said. MOODY AND WILLIAMS speculate there is a lower overall rate of suspen- sion in segregated schools. "There are no racial overtones to worry about in a segregated school," Williams said. Moody added, "In an, all-white school, the teachers probably feel they can handle whatever situation comes up without having to worry about provipg they weren't racist, and they are less likely to punish kids for fighting." A misunderstanding of the way black children communicate can also lead to insubordination accusations, Moody said. "It is typical for black children to have a style of bantering back and forth with adults," he explained. "A teacher can misinterpret that to indicate a lack of respect."r Moody added ,all. teachers, black a nd , white-discipline black children dif- ferently. "The structure of the system determines its outcome," Moody said. Disciplinary action is a reflection of a teacher's social class, he said, not of his or her race. OVERALL, THE USE of suspension as a disciplinary method has increased over the years, the researchers said. In the '60s, suspension became an especially prevalent method of discipline due to the backlash from unrest on college campuses, Williams said. Today, the rate of suspension in public schools is decreasing, according to oublic school statistics.
