Aerial reconnaissance and photography are of great importance in the study of the early history of Fenland and the surrounding country, conditions often being A very suitable for this method of investigation. A vast amount of information which can be recorded easily by air-photography, would only be obtained with the greatest difficulty, if at all, by field-work on the ground. The present paper is a brief record of observations made while flying over the fen basin during the course of duty. Unfortunately photography was not practicable, but systematic notes were kept of everything observed. Further work should reveal much more.

11 It is difficult to find similar groups of barrows or circles in England, but close parallels are seen in Dutch urnfields, for example those published in Oudheid. Meded., XIV (1933), 26 ff. and XVII (1936), 38 ff, where numerous small circular ditches and occasional double circles and long ovals are seen. These are of Iron Age date.
