1900: IORM invite in Jargon

Fraternal organizations among Settlers in the post-frontier era embraced Chinuk Wawa as a language of in-group identity, writing invitations for their social events in this language.
Skokomish Tribe, I.O.R.M, have invited their brethren and friends to a grand dance on Saturday evening, Sept. 22nd. The invitation is in delate [real] Chinook jargon.
