...just above the dark (clay) layer in this picture.
Ground water soaks down through the upper gravelly/sandier layers until it
reaches the impermeable clay. The cast-iron water main has now disappeared

replaced by BT cables, suspended in mid-air. 28/2/06 |
| An interesting picture showing a cross-section about 24"
deep with the modern tarmac road surface at the top. Further down, the
layer of large stones with a layer of finer stone above them were most
probably the road surface prior to the days of tarmac. So when Nos. 4 and
5 St Andrews Cottages just behind were built in about 1901 or 1902 -
before tarmac roads in Harberton - the crushed stone surfaced road was a
lot lower. 28/2/06 |
