two other possible examples, the Coffin Stone and the White Horse Stone. About east of the Medway Megaliths are the Stour long barrows. This distinct regional grouping consists of three known mounds: Jacket's Field Long Barrow, Julliberrie's Grave, and Shrub's Wood Long Barrow. These are located within of each other, high up on the North Downs between Canterbury and Ashford; Jacket's Field is on the western side of the River Stour and the other two on the eastern side. Unlike the Medway Megaliths, the Stour long barrows do not appear to have used stone as a building material. Their builders' decision not to do so was likely deliberate, for sarsens are naturally present in the local area and could have been obtained had they wanted them. The presence of the long barrows suggests some sort of settlement nearby in the Early Neolithic period, and two polished flint axes from the period have been found at Soakham Farm, not far from Jacket's Field Long Barrow. The North Downs trackway may have been in use at the time, and would have provided routes for local people to travel west. Elsewhere in southern Britain, long barrows were often erected close to causewayed enclosures, although none of the latter have yet been discovered near to the Stour long barrows. Elsewhere in the southeast, there are other long barrows of the period; over away from the Stour long barrows are another regional cluster in Sussex, while a solitary long barrow is known at Badshot Farm in Farnham, Surrey. Description Jacket's Field Long Barrow is "slightly trapezoidal" in shape. It aligns on an east/southeast to west/southwest axis. It measures approximately in length, with a width of at its eastern end and at the west. At its western end, it reaches in height, and at the eastern end almost . There is evidence of side ditches that once flanked the mound. Discovery While Julliberrie's Grave had been known to antiquarians since at least the 16th century, Jacket's Field Long Barrow—as well as Shrub's Wood Long Barrow—was only discovered by later archaeological investigation. The archaeologist Ronald Jessup, who excavated Julliberrie's Grave in the 1930s, suggested the likelihood that other long barrows would also be found in the area. In 1970, J. Bradshaw reported in the Archaeologia Cantiana, the journal of the Kent Archaeological Society, that Jacket's Field Long Barrow had been discovered within dense woodland and reported to
