[ T. C. Browne A stone retaining wall with each stone fitted, with its neighbour. A good feature is the large stones at the base and the smaller ones at the top. The interstices between the stones prevent the build-up of pressure of the weight of moisture and sodden soil in wet weather, if this wall were to be used for growing plants, the stones would be better trimmed and built horizontally, I to 3in. of soil placed between them, and the stones bonded. Drainage behind, through, and at the foot of the wall is also required and is essential in wet districts Coverage of the wall as it is would best be achieved by insertion of trailing plants at the top and small shrubs and climbers at the base; in 2 or 3 years very little of the wall would be visible.
