'Their funerals take a most hideous form. Owing to a lack of fuel with which to cremate the corpses, the dead are carried to the hillside where the body is cut up into pieces and left in the open for the vultures to devour the flesh after which the bones are picked up and then crushed into pulp between stones.'
