lu 1855, the Smithsonian Institution published a Vocabulary of 

 the Jargon or Trade Language of Oregon, from a manuscript fur- 

 nished by Dr. B. Rush Mitchell, and edited by Prof. W. W. Turner. 

 This was necessarily very imperfect, and in fact was printed mainly 

 with the view of eliciting additions and corrections, which might be 

 used to prepare a more perfect account of this very remarkable mix- 

 ture of language. The present work, which is much more complete, 

 has been prepared by George Gibbs, Esq., from materials collected by 

 himself during a residence of twelve years on the northwest coast of 

 North America.
