This rock is native Lewisian Gneiss (pronounced nice), one of the oldest known rocks on the earth's surface. It was formed in the pre-Cambrian geological era. The Western Isles share this geology with Greenland and part of Canada which lay together before the Atlantic came between. This two-ton specimen€, exhibited in Stornoway Library, was quarried at Marybank, Stornoway, and shows typical banding of green horneblende, black biotite mica and pink and white feldspars and quartz - the record of its ancient formation.
So why is this an experiment? The answer is I have scheduled this posting to see if the scheduling is working again on this blog. One lives in hope...
Later - experiment failed - posted manually. Bummer!

I'm a blogger - and nowadays that seems to be my main occupation. Rambles from My Chair is my main blog. I’m a retired local government executive - now studying how to survive a neurological disorder that gives me various problems but, hopefully, a whole new outlook on life and an increased sense of humour and perspective. There is a saying in Sweden "man måste vara frisk för att orka vara sjuk" ~ "you have to be well to cope with being ill"....
I enjoy most forms of communication and postcards are a special favourite. I used to blog as Scriptor Senex which is Latin for Old Writer but now Google only lets me post as John Edwards.
