37 damming streams and gravel extraction during the construction of the 1830's toll road which is known as the A.11 - although now officially a B road. If you should drive along it, through the forest, notice how the land on either side rises and dips whilst you stay horizontal. The largest Wake Valley pond once had a diving board but it is now too silted for swimming, apart from being forbidden as too polluted for humans. It was here, two years ago (14.4.1984) that the Field Club meeting spent much of its time counting the number of toads. This year we saw none and blame this on the cold winter/spring. (At the time of writing 26.4.1986, they're arriving hourly.) Newly placed wooden stakes hold the dam of the smaller pond to the east of the road. From the large pond we walked southwards passing a bomb crater, now a pond with its tell-tale rounded shape and raised bank, to the smaller Wake Valley ponds, then crossed and followed the 'sawdust ride" to its junction near the Clay Road. Only a short by-pass stretch is left to show the effect of this experiment about 10 years ago. Apart from being tiring to walk on, the sawdust rotted to become a smelly bog colonised by soft rush and algae. The ride has been recently freshly surfaced with sandy gravel. Next to Loughton Camp - with its dry ditches and soggy stream starting within their circle. Here there is the leaf-filled marsh of the old charcoal-burners' pond; very little grows in it as the beech canopy is so dense in summer.
