Yes, was flicking through it last night. He says that the Hund / 'barking like a dog' description comes from Agricola which I've never been able to summon up the energy to read properly. He goes on to say that Agricola's explanation has been challenged with the suggestion that it comes from the Czech (or somewhere in those parts) word Hunt meaning carriage which is entirely plausible.
He does go on to describe an early long, narrow tub in Barneycraig which sounds very much like the tub in Smallcleugh towards the end of the Middleceugh 2nd Sun Vein, just past the point it crosses Longcleugh Vein.
That tub is outbye of VM workings so presumably isn't that old though its not to say the pattern isn't I suppose.
