In April 1898, the expedition arrived at its field of work and spent over a year in the Torres Strait Islands, and Borneo, and brought home a large collection of ethnographical specimens, some of which are now in the British Museum, but the bulk of them form one of the glories of the Museum of Archaeology and Anthropology, University of Cambridge. The University of Cambridge later passed the wax cylinder recordings to the British Library. The main results of the expedition are published in "The Reports of the Cambridge Expedition to Torres Straits". Haddon was convinced that hundreds of art objects collected had to be saved from almost certain destruction by the zealous Christian missionaries intent on obliterating the religious traditions and ceremonies of the native islanders. Film footage of ceremonial dances was also collected. His findings were published in his 1901 book """   Similar anthropological work, the recording of myths and legends from the Torres Strait Islands was coordinated by Margaret Lawrie during 1960–72. Her collection compliments Haddon's work and can be found at the State Library of Queensland   In 1897, Haddon had obtained his Sc.D. degree in recognition of the work he had already done, some of which he had incorporated in his "Decorative art of New Guinea", a large monograph published as one of the Cunningham Memoirs in 1894, and on his return home from his second expedition he was elected a fellow of his college (junior fellow in 1901, senior fellow in 1904). He was appointed lecturer in ethnology in the University of Cambridge in 1900, and reader in 1909, a post from which he retired in 1926. He was appointed advisory curator to the Horniman Museum in London in 1901. Haddon paid a third visit to New Guinea in 1914, and returned during the First World War. Accompanied by his daughter Kathleen Haddon (1888–1961), a zoologist, photographer and scholar of string-figures, the Haddons travelled along the Papuan coast from Daru to Aroma. While less discussed then his earlier work in the Torres Straits, this trip was influential in helping shape Haddon's later work on the distribution of material culture across New Guinea. The war effort had largely destroyed the study of Anthropology at the University, however, and Haddon went to France to work for the Y.M.C.A.. After the war, he renewed his constant struggle to establish a sound School of Anthropology in Cambridge. On his retirement Haddon was made honorary keeper of the rich collections from New Guinea which the Cambridge Museum possesses, and also wrote up the remaining parts of the Torres Straits Reports, which his busy teaching and administrative life had forced him to set aside.
