** ADVANCE FOR WEDNESDAY, JULY 11 **FILE**A wooden cross, a World War I shell and other mementos mark the place where Lancashire Fusiler Harry Wilkinson was killed in action in 1914 at St. Yvon, Belgium, in this Dec. 24, 2003 file photo. All along the so-called 30 kilometer salient and ridge that surrounds the nearby city of Ieper, better known to the soldiers of the 1914-18 World War by its French name, Ypres, farmers collect some 200 tons of metal a year, mostly shells, grenades, and gas canisters some of which pose a serious safety risk.
