176 THE ESSEX NATURALIST A section of the track which is strongly representative of the whole stretches from Cobbin's Brook (453043) to Pepper's Green (620106) and is here treated in detail. 1. The Cobbin's Mound (453043) is in line with the track from Deerpark Wood (405040) along the southern brow of the Epping Upland ridge, passing a few hundred yards south of Epping Upland Church. It was discovered by Mr. H. B. Kemsley, of Jack's Hatch. Here the bed of Cobbin's Brook has been diverted into an almost circular channel, producing a central mound nearly twenty feet above the brook level. This mound is con- nected to the adjacent field by an unbroken causeway at its northern face. The diameter of the bend in the stream around the mound is about 100 feet. 2. The Hayley Manor stone (458049) now rests on the side of a ditch 200 yards east of the farmhouse. It was discovered by the plough buried on the summit of the highest elevation, about twenty yards east of its present position, by Mr. W. Padfield, of Hayley's Manor. It is an irregular block of Herts conglomerate about three feet long, and in its original state was probably mounted on the top of the hillock where it would be in view from the Cobbin's Mound, four furlongs to the south-west. Thus, the track changes direction at Cobbin's Mound, evidently to avoid the low ground of the Cripsey stream away to the east. 3. The Cross Keys stone (468057). Five furlongs beyond the Hayley stone, in the same north-east direction the track reaches the main Epping-Harlow road, and in a field opposite the Cross Keys Inn, not two yards from the hedgerow, is an inconspicuous block. We were told that it is deeply embedded, having resisted an attempt to remove it. The most arresting feature of this stone is its shape, the exposed portion being that of a half-moon disc, about six inches thick and two feet in dia- meter. It has been placed in the ground with the narrow edge orientated in the north-east direction of the track. The impres- sion is created that the stone emphasises this northern component of direction, to deflect travellers away from the low lying, marshy and heavily-wooded valley of the Cripsey. 4. The Canes stone (482065). Canes Farm lies a mile away to the east-north-east of the "Cross Keys." The farmyard occupies the ancient site of Canes Priory, and here we found a conglomerate block almost buried in the ground in front of a stable. In all probability this is not its original position. The track beyond Canes Farm follows the southern brow of the ridge overlooking North Weald, and for the next mile no stones or other evidence have yet been found. 5. The Mollman stone (504075). This stands outside Moll- man's Farm, on the roadside where three roads meet. Originally
