A story on Page A1 yesterday about a U.S. Supreme Court case involving a border fence incorrectly said that at least 2 million cubic tons of dirt would be needed for an earthen berm across the canyon to support the fence and all-weather patrol roads. In fact, it will require at least 2 million cubic yards of dirt.
