A preliminary excavation of this barrow was made in 1936 and an account of the work then undertaken, together with a detailed topographical description of the site, was published in this Journal for April 1937 (vol. xvii, p. 122). The admittedly tentative conclusions which could then be advanced regarding its date and its relationship to the characteristic Neolithic longbarrows were largely based on extrinsic evidence, and positive indications obtained during the excavation itself were not as definite as could be wished. In 1937 Sir Edmund Davis suggested that in view of the significant geographical situation of the barrow further investigation was desirable, and he very generously again agreed to be entirely responsible for the cost. Altogether the work occupied some eight weeks, and during the college vacation I had the valued assistance of Dr. S. Graham Brade-Birks, Head of the Department of Geology at the South-Eastern Agricultural College, Wye. Mr. H. B. Bescoby, Head of the Department of Surveying at Wye, and two of his students, Messrs. D. Vickers and H. Castel, very kindly prepared a contour plan of the barrow, upon which the general plan (pl. XLIX) is based. My best thanks are also due to Dr. A. J. E. Cave, Dr. J. Wilfrid Jackson, Mr. A. S. Kennard, Mr. B. H. St. J. O'Neil, and Mr. Stuart Piggott for their contributions to this report, and again to Mr. H. Read Gillett, Sir Edmund Davis's agent, for many kindnesses.
