I shall close the account of the Tshinúks with a notice of the Lingua Franca, taken from Mr. Hales, which is now in the actual process of formation in the parts about the mouth of the Columbia. It first began to be developed in the harbour of Nútka Sound; from the language of which district a few words were adopted by the early English traders. When the intercourse with the inhabitants of the Columbia began, these Nútka words became transferred to the Chinúk country; and the three languages which then contributed elements to the so-called _jargon_, were the Nútka, the Chinúk, and the English. From the second of these tongues were taken, besides certain substantives and adjectives, the first ten numerals, the word for a hundred, twelve pronouns, and about twenty adverbs and prepositions. Additions were also supplied from the French of the Canadian _voyageurs_. Some of the processes by which this medium of communication has been formed deserve study; and they have been well exhibited in the philological portion of the United States Exploring Expedition, the source of the present information. 1. For a language to be spoken by three different nations it is convenient to admit only such articulations as are common to the three languages. An approach to this occurs here. The harsh Chinúk sounds are modified. The French nasal is dropped. The English _tsh_ becomes _dzh_; perhaps, in the mouth of a Frenchman, _zh_. 2. In names of objects common to both languages, the choice seems to be determined by the hardness or easiness of the pronunciation. For _man_, _sun_, _moon_, _stick_, _snow_, _warm_, &c., the terms are English; although the equivalents were part and parcel of the Chinúk and Nútkan, equally. They were, however, preeminently unpronounceable, being _kottllelikum_, _ottllatl_, &c. On the other hand where the Indian is moderately adapted to European organs terms from _both_ languages become current, _e.g._ ENGLISH. JARGON. Water _tsok_ and _wātā_ Cold _tsis_ " _kol_ Fire _olapitski_ " _paia_. 3. Grammar is, as we should expect it to be, at its _minimum_ amount. _a._ _b._ There are no signs of either the possessive case or the plural number. The former is determined by the construction only--_kata nēm maika papa_=_what name thou father_=_wh(-at) is (the) name (of) th(-y) father_. The latter is sometimes denoted by _haiu_=_many_. _c._ In general the tense of verbs is to be discovered by the context. When it is absolutely necessary to fix the time, certain adverbs are resorted to; as, _now_, _formerly_, _tomorrow_. The future sense is expressed by _tuké_=_wish_. _d._ The notion of condition is expressed by the Chinúk _klunas_=_perhaps_, or by the English _pos_=_suppose_. The only other conjunction in the language is _pi_ =the French _puis_=_and_, _or_, _then_, &c.
