were either damage to the original structure or meant that the enclosure was unfinished, and that a plan should show the layout without gaps. The causeways separating the ditches and the associated gaps in the banks were first noticed by Veronica Keiller, the wife of the archaeologist Alexander Keiller. E. Cecil Curwen surveyed the site with a boser—a heavy rammer used for detecting underground bedrock, or the lack of it, by listening to the sound made when the boser strikes the ground—and published a plan of the site in 1929. Curwen also listed it as a possible Neolithic site in his 1930 paper "Neolithic Camps", which was the first attempt to assemble a list of all the causewayed enclosures in England. Only one of the three barrows nearby has been investigated: Leslie Grinsell reported in 1934 that one had been opened by Major F. Maitland, in 1907, and in 1941, Curwen's father, Eliot Curwen, published a short note describing the finds, which had been donated to the Sussex Archaeological Society's museum by A.F. Maitland, the Major's son. The finds consisted of four bronze axes in excellent condition: one complete, two that had been deliberately broken in half, probably as votive offerings, and the blade from a fourth. The axes were found under a large stone, "estimated to have been about 3 cwt. in weight" (about 335 lbs), in the barrow to the west of the enclosure. G. P. Burstow visited the hill in August 1945, and found Romano-British pottery and half-a-dozen Roman coins exposed at two or three places near the top of the hill, in some cases in tracks worn by army vehicles; an additional Roman coin was found in 1947. All were donated to the Sussex Archaeological Society's museum. The coins dated from the mid 3rd century to the early fourth century AD. In 1980, a metal detectorist found a hoard of 144 Roman coins on the north slope of Combe Hill. The latest coins in the hoard come from the reigns of Tetricus I and Tetricus II, so the hoard appears to have been buried towards the end of the third century AD. Musson, 1949 In 1949 Reginald Musson excavated Combe Hill for the Eastbourne Natural History and Archaeological Society, to determine the accuracy of Curwen's plan. He began by opening the north end of a ditch on the west side (at the south end of trench
