1906: A Wapato invitation
An addition to the post-frontier “Chinook invitations” file:
It’s not translated.
(The newspaper editor felt readers of the pioneer generation, who were the intended guests, would understand its rusty but good Chinuk Wawa.)
But a generation gap was emerging: this article is massively misspelled.
(The printer’s devil was too young to have a pioneer’s knowledge of the language he was typesetting from a handwritten manuscript.)
(As a result, we now have unusual trouble making out its details.)
A Wapato Invitation.

‘come, your friends will be disturbed.’
— from the Yakima (WA) Herald of May 2, 1906, page 6, column 2
tíki yáwá cháku  — The way this is worded, it says a bunch of people want to come here, whereas what was intended was that they want you folks to come here; a pronoun was left out, either through lack of recent practice with the language, or due to that printer’s devil who I mentioned, or both. On the other hand, fluent Jargon is shown in the placing of the adverb ‘here’ before the verb ‘come’.
tíntin  for ‘music’ is the real McCoy. In other places, this word only means ‘bell’, but fluent Settlers understood it as ‘music’, as we’ve seen in other Chinook Jargon invitations.
mamuk-táns  as a noun ‘dancing’ is unusual. Just plain táns would be normal. However, the writer shows awareness of the differences between real Jargon & English, in that the former does typically express the verb ‘to dance’ with the mamuk- Causative prefix.
də́chmən háyás háws  — this almost certainly indicates a ‘German hall’, the headquarters of a fraternal/social organization where dances normally were held, such as we still have here in Spokane. If ‘the German (guy)’s large house’ had been meant, the writer would presumably have used yaka ‘his’ before ‘large house’.
kʰə́ltəs-tə́mtəm  — ‘no.good heart’ literally — this is a novel expression to me, but it’s well-formed, and it may have been a locally common expression. (If it wasn’t another product of a pioneer’s atrophying Chinuk Wawa.)
