Ground is broken for the new Smithsonian Environmental Research Center laboratory at the Center's site in Edgewater, Maryland. The building, to be named the Charles McC. Mathias, Jr., Laboratory, is scheduled for completion in the fall of 1988. The Center is named in honor of Mathias, former U.S. Senator from Maryland, because of his many years of championing legislation to protect the Chesapeake Bay from overdevelopment and pollution.
