188 THE ESSEX NATURALIST. Accordingly Mr. Hatley and I set out to explore. We walked from Dunmow, through High Roding and Aythorpe Roding, and across the fields to Hatfield Broad Oak. After a short stay we continued on foot until we reached Bishop's Stortford. The charm of the district held us, and we determined to come again for a longer stay. The opportunity was not forthcoming for another five years, but in that time the desire to make a study of the region gradually took shape. At Whitsun last year I undertook to conduct a week-end party to Hatfield Broad Oak in connection with the S.W. Essex branch of the Geographical Association. Thus in the Spring of 1928 three visits were paid and a further one in August, when, armed with 6 inch maps, Mr. Hatley and I enjoyed the peaceful intimacy of field and hedgerow and the mellow beauty of ancient farmhouse, village church and moated grange. So interested had we become in the district that it was quite natural to conceive the idea of undertaking some part, at any rate, of a regional survey. The habit of thinking in terms of regional study is one which grows, for from such study the individual secures ever widening interest in nature and in man. My own introduction to the value of regional survey work was a paper on Saffron Walden given by Mr. George Morris at a meeting of the Essex Field Club.1 The inspiration of that meeting has remained with me ever since and led me to combine the field studies of the naturalist with those of "man and his work" which are fostered by modern geography. Geology became, for me, a background for geographical thought, while biology and architecture were both considered in relation to man. Thus I approach regional survey as a geographer and naturalist rather than from the sociological side. Regional study and survey have been developed in this country through the influence of two pioneers, the late Prof. Herbertson (geographer) and Prof. Patrick Geddes (historian and sociologist). It is held by many that the development of any district should be based upon a wide view of its relations to surrounding districts and of all its internal economy. Such a view involves comprehensive knowledge of the region, its natural physical features, the geological structure and surface soils, climatic characters, the lines of communication, and some insight 1 Essex Naturalist, vol. xix., Regional Survey of Saffron Walden, 28th February, 1920.
