We are quite used to hearing about pollution these latter days; but I remember as a young lad, how on cold windy days, in February, as the wind persisted from the east or south east for days, the smog of Glasgow darkened the skies over Tiree. After a few days the sheeps' wool would become dark in appearance. Since the advent of smokless zones, this no longer happens. It all goes to show how a situation can change over a number of years.
Heather is not a problem in Tiree so we didn't have to burn it; but I can well remember the Febuary burnings in other islands and the mainland to the east of us and how we could see the fires at night, while the smoke and the smell wafted towards where we were.The air was then filled a beautiful peaty odour that was welcome rather than abhorred. Part of the highland crofting way of life, possibly.
These rather unusual happenings now-a-days would surely be deemed to be pollution and be prohibited as unsound. But heather burning in days gone bye was considered a necessity, simply to let new grass develop. Just like so many other traditional activities we don't see it any longer. Anyway, The wellbeing of the world is upper most in our minds now.
