PHOTOGRAPHIC EDITOR:
ERIC HOSKING F.R.P.S.
The aim of this series is to interest the general reader in the wild life of Britain by recapturing the inquiring spirit of the old naturalist. The Editors believe that the natural pride of the British public in the native fauna and flora, to which must be added concern for their conservation, is best fostered by maintaining a high standard of accuracy combined with clarity of exposition in presenting the results of modern scientific research. The plants and animals are described in relation to their homes and habitats and are portrayed in the full beauty of their natural colours, by the latest methods of colour photography and reproduction.

FOR MANY years Dr. F. Fraser Darling has found his field of work in the Highlands and Islands of Scotland. One of his pioneer researches was into the social behaviour of a herd of red deer, in an area of Wester Ross dominated by the massif of An Teallach. In 1936 he began the first of two seasons’ work on Priest Island of the Summer Isles, studying the social structure of gull colonies and of small flocks of grey lag geese and other gregarious birds. It was from this work that Dr. Darling was led to enunciate his theory connecting the size of a social group of gregarious animals, with its breeding-time, and breeding-success. Statistical analysis and further observation by other workers have confirmed this theory and shown it to be of wide biological importance. Darling then made protracted autumn and winter visits to Lunga of the Treshnish Isles, and to North Rona, in order to study a further type of animal sociality, that of the Atlantic grey seal, an animal of whose life history we knew surprisingly little. He also worked his small farm on Tanera in the Summer Isles in such fashion as to show that it was possible and reasonable to raise considerably the stock-carrying capacity of the West Highlands and to grow a large amount of human food under crofting conditions.
Fraser Darling is a born naturalist, was brought up to farming, and became a scientist as thoroughly and quickly as academic discipline permitted. His first researches (at the Institute of Animal Genetics, Edinburgh University) were on the Scottish Mountain Blackface breed of sheep. He combines the qualities
