Howdy from tax-free Skookum, Oregon
The local news leads off with a reference to the local Lake Wobegon of its day, Skookum, Oregon:
(By the date of publication, “skookum” was already established in English dialect and slang, so the town’s name is intended as the boosteristic “Wonderful”.)
I am much interested in reading the items from “Skookum.” They are unique. I don’t know where the place is located, but I know the writer. “Hyas cumtux mamook sum. Clonas yaka close tillicum pe nika hyas ticka nanitch yahka copa yahka ilahee. Wakelala nika chahco copa, pe nanitch mika klosh kahkwa.“
— from the Toledo (OR) Lincoln County Leader of December 10, 1915, page 1, column 1
A look at some issues of the same paper just preceding this one shows that there was a recurring feature of outrageous news, usually political tussles over taxation, from this fictional Podunk burg.
Equipped with that background information, I’ll venture a go at this post-frontier, more-or-less fictional, Chinuk Wawa note (from the editor?):
Hyas cumtux mamook sum . Clonas  yaka close tillicum  pe nika hyas

nanitch mika klosh kahkwa .

see you good thus.
‘see that you’re all right by doing so.’
 mamook sum pretty certainly means ‘writing’; I’ve seen this spelling in other periodicals of the era. Otherwise, it could mean ‘do sums, do math’, in reference to the abovementioned taxation and budgeting arguments. I doubt that.
 clonas can mean ‘I don’t know’, or ‘maybe’. Here it’s an evidential marker indicating a surmise.
 tillicum could mean ‘person’, but the more usual sense from White people of the time was ‘friend’. The context supports this idea that the editor has a certain person in mind.
 The second occurrence of copa seems to be that good Oregon-dialect adverb kʰapá ‘(over) there’, in contrast with the first occurrence, which is just a preposition.
 klosh kahkwa is pretty straightforward, but I feel duty-bound to mention that this is also the expression for ‘amen’ in Christian prayers such as JK Gill’s version of the Lord’s Prayer, which had been published a number of times in Oregon newspapers over the preceding decades. Could it be a clue to the friend’s identity (as a preacher maybe)?
Summarizing, today’s text strikes me as reasonably skillful Chinuk Wawa that’s true to local ways of talking.
