In a few villages on the west coast of Papua New Guinea, a handful of men still practise the ancient ritual of sharkcalling, going out to sea in small outrigger canoes to call, trap and kill sharks by hand. It is the method by which they could contact their ancestors, reaffirm belief in their god, and demonstrate their ritual powers. But when the present generation of sharkcallers die, this spectacular and dangerous ritual will probably die with them.

Reporter Eric Robson
Two-thirds of Glasgow's East Enders have been moved out of the area. But they still come back to what's left of the streets and pubs of home. Many stand on the Celtic terraces or march in the bands of the Orange Lodge because the rituals of the Pope and King Billy give them a reason to return. Frank Kirk travels nine miles every day to drink with lifelong friends at The Bowlers. ' They may have destroyed this area, but we have still got that community spiritl ike magnetism-people sticking together through thick and thin.'
