It is COLD here and getting colder. Send me a pair of those gloves and I'll
give them a test.

There's something else interesting about certain Lichens - certain types
only thrive in the presence of high concentrations of lead.
This was taken advantage of in the early days of leadmining in the
Yorkshire Dales, patches of the right strains were seen as indicators of
ore-bearing ground and led to the discovery of many orefields and near
surface deposits in Swaledale.
On a completely different tack - my father used to collect lichens for
making dyes for wool, one of his favourite hobbies was spinning wool and
knitting wool direct from fleeces into pullovers and gloves.
I still have many pairs of his handknitted gloves made of narurally
dyed, homespun Swaledale wool. Even in the deepest winter you have to
keep taking them off because otherwise your hands are much too warm!
Cheers
Douglas
