one of his first and most famous anthropological studies was with the Trobriand Islanders of New Guinea inthe southwest Pacific from 1915 to 1918. He studied their day-to-day life and learnt their language. He was particularly interested in their beliefs and one of their rituals called"the Kula Ring". The people on the different Trobriand islands gave and took two types of objects from each other: a necklace or a bracelet. The islanders would sail long distances to exchange these gifts with people on other islands. Necklaces travelled clockwise and the arm bracelets travelled anti-clockwise.
