Re 30A - the def is in Chambers (#4), but finding a reference ? Good luck.
Best I could do are these:

"Public! - Sweepclean, the messenger, will be there the day wi' a' his tackle. I ken it frae ane o' his concurrents, as they ca' them, that's warned to meet him - and they'll be about their wark bleyve - whare they clip there needs nae
kame - they sheer close eneugh."
I can't decipher enough of that to determine the meaning.

Pg 249 - 2nd def of
KAIM (they were rather loose with their spelling back then)
Also, scroll down to pg 250 - 2nd def of

Any further ideas?
