And the BI's have a long history of building them and making them work efficiently and sustainably.
And they were smart enough to not bother building them when there was more surface rock than soil ( Like uncivilized Wales and Scotland)
Excusing any implied racism , let's just say the flatter earthmen were more sensibly engaged than the Lords of rocks, mountains and hunting because they needed food to grow, store sell and had no deer to chase (much)
I was giving these old Islanders heaps because where I was brought up, we have a thing called sand and it's beautiful. We Aussies have coastlines full of it and heaps of history of our Creator grinding and tilting it up, so there would be some even after sea level rise, climate change and glacial events.
Sand can be used to build great fences, but you have to have some handy.
With Australia's backbone in Granitic type igneous we have an arenaceous culture, while the poor old Brits are stuck with largely an argillaceous one .
I could go on --to a study of how they are stuck in the mud sorts but then we Aussies have our disaster prone duplex soils. whose fine sandy component is both a blessing and a curse .
When you see these old sailors trying to sit comfortably on gravel ,its no wonder all the Brits still love Dee Why and Home and Away.
Perhaps YOU know of some great quartz beaches there - I struggled to find even just a few ,
Anyway I won't have time to finish this today except to say that it was a great surprise to discover both Granitic and Glacial at Gatehouse yesterday.
What perfect pieces these various sized rock pieces were (with their flattish fractures) for fencing . Plenty of gaps for their beautiful wrens.
Let's work with nature not as some of the newbies to conservation ( I call them Echoists) do and we who insist we just worship nature as it is. l, Let's not join those cynics who cancel those whose work with nature is imperfect. Lets understand it so we understand and build on its symbiotic nature . Nature is our sister not our mother ( GK Chesterton )
