What does "noust" mean?

I'm translating George Mackay Brown's "St Christpher" and came upon an unintelligible piece of text, here it goes: "Christopher said, sailing back to the NOUST of the island, 'I hope my wife doesn't smell the honey of that kiss (...)" Another thing that troubles me is... show more I'm translating George Mackay Brown's "St Christpher" and came upon an unintelligible piece of text, here it goes:

Another thing that troubles me is "I am going to be married tomorrow in the island with the blue hills."- does it simply mean an island with some blue hills in it, or is there anything else to it (the fragment concers Scottish islands, if that's of any matter)?

Thanks a lot in advance!
