The first is that such a date could only be from radiocarbon dating (and should therefore have been quoted with its appropriate standard error). Radiocarbon dates of 40,000 bp and above are uncomfortably close to the practical limit of radiocarbon. The quantity of radiocarbon remaining in wood and other living matter diminishes by half with the passage of each 5730 (more or less) years after the death of the organism - thus after 40,000 years only one part in 128 of the original radiocarbon remains. Given that at the [...]43_17Jan200216:25:[log in to unmask]

"I understand that a plan showing the workings at nearby Tankersley shows galeries radiating out from the shafts. When some of the shafts in the Emley / Flockton area were exposed during opencasting in the 1950s it is reported that similar galleries were seen. This is however only an oral account and they were not recorded." [...]50_18Jan200201:28:[log in to unmask]

The hills around Brightling are pock marked with the remains of these pits.

Both of these come from Bryan Earl's excellent book 'Cornish Explosives'
