it means,main certificate(direct translation would be certificate big/large[but mor also means of great importance in Irish])
would be pronounced, taas-tiss moor(obviously said quickly1)
it says in that blog that the aim is to dig down on the critter,surely it's down onto the dog not the quarry,were you to dig onto the quarry you'd be putting alot of pressure on the dog to keep it bottled up.
it also says badgers are still dug in Ireland even though it's illegal,a very helpful statement
the guy seems to have more opinions than knowledge on this subject
