40 EPPING FOREST of several acres, surrounded by an unsightly six- foot iron fence, which is intended to serve the purpose of a " field pound," but is rarely or never used, the track strikes across the thicket to the north-east, and steers for the group of tall fir-trees in Copped Hall, a landmark which is occasionally visible. Crossing the road which leads to Copped Hall Lodge, the track conducts into the Epping road nearly opposite Ambresbury Banks, an ancient British Camp described in the following chapter. Its position is indicated by the group of lofty beech and oak trees which have established them- selves on the banks. Immediately to the left of the camp a beautiful glade, arched by fine beeches, leads diagonally from the high road into the broad "green ride" which is parallel to it, and which may be followed to Epping. This walk may be recommended in wet weather, as it leads over high ground and gravelly soil.

Thence the road leads to Debden Green in about a mile. A few yards before reaching the latter, at a gate on the right, a notice-board indicates that there is a right-of-way across the field to the Forest. From the point where the latter is entered a broad glade, overgrown with brake fern, ascends the hill. Look- ing back to the south over Loughton, there is a fine view of the Thames Valley to Kent. At the top of the hill there is a wide plateau, with scattered pollard oaks growing on it, but in summer covered with a dense growth of brake fern. Cross this in a westerly direction to the old roadway known as " The Ditches" which bounds the plateau on the west. On the farther side of this roadway look for a gap in the thicket. This is the top of Cop- ley Plain—a grassy hollow which leads down into
