<HTML>The only one pathetic here is you.
>This has no relationship to the iron twist forks used on travertine in the 19th century or other old methods. And quarrying with pointed picks, probably made of stone, has no relationship to modern methods, like chains saws used to slice up quarry faces.
Did I talk about chainsaws? No, I told about Neuburgers observation of antique quarries and about his conclusion, that at his time the methods were the same as in old antiquy. Especcially the sandsaw-methods used on processing the stones are explained and even antique authors quoted (like Plini) who explain the methods (toothless copper saw blades with sand) still used in roman times.
And id I dig a trench with a chainsaw or with a pick is essentially the same. The problem was: You were asked where do you get your number of 75% wastage from - you couldn't answer it, so you are evading again.
Ah, by the way: Where do you get your "30 feet of waste" from? I have not seen this, the lime stone is hard and was quarried up to the top. Or are these 30 feet again guuesswork? A completely vanished strata only you, Mrs. Morris and Edgar Cayce know from?
The other problem: Wher have all the millions of cubic meters hard limestone gone which once were in the quarry areas???? Vanished into thin air?
