18th.  Finished my report on the additional debt claim, under the treaty of 1836, agreeably to the instructions of the Commission of Indian Affairs, of the 23d March last, and to the published notice of April 10th.  These claims on the debt fund of the treaty have received the best consideration of the agent and the Indian chiefs, with the aid of a secretary authorized at Washington, and the result is forwarded with confidence to head-quarters.

19th.  My arduous duties during the summer had thrown some of my private correspondence in the rear.  It may now be proper to notice some of it.  A letter (Aug. 20th) from St. Mary’s says:  “The schooner John Jacob Astor arrived on the 18th instant from the head of Lake Superior, and the captain brings us information of Mr. Warren’s arrival at La Pointe.  He attended the treaty at St. Peter’s, concluded by Gov.  Dodge.  The Indians are to receive $700,000 in annuities for twenty years, $100,000 to the half-breeds, and $70,000 for Indian creditors.”

“Captain Stanard brought down a specimen of native copper, similar to the piece of forty-nine pounds weight in your cabinet.  It was at De l’Isle, fifteen leagues on the north shore from Fond du Lac.”

Mr. John T. Blois, of Detroit (Sept. 20th), informs me that he is preparing a Gazetteer of Michigan.  “Of the topics,” he remarks, “I had proposed to submit to your consideration, one was the etymology of the Indian nomenclature, to the extent it has been adopted in the application of proper names to our lakes, rivers, and other inanimate objects.  In the preparation of my work, this subject has frequently presented itself to my mind as one of interesting importance, and whose development is more auspicious, at the present time, than it may be at a future day.  I had a particular desire to rescue the Indian names from that oblivion to which the negligence of the early settlers of other States has permitted them to descend, by the substitution, for no reasonable cause, of insignificant English or French names, without regard to either good taste or propriety.

“I wish, among other things, to ask of you the favor to inform me of the origin and signification of the name of our adopted State, Michigan.”

A correspondent at Detroit (J.L.S.) writes (21st Sept.):  “Bills have been introduced into both Houses to carry out the President’s sub-treasury system, and ’tis said Calhoun will support the measure.  These bills, which were introduced by Wright and Cambreleng, propose that treasury notes shall be issued not to exceed $12,000,000.”

Mr. Palfrey (25th Sept.) suggests my reviewing Col.  Stone’s “Life of Joseph Brant,” and the publishers (Geo. Dearborn and Co.) transmit me the proof sheets on sized paper.  I sat down with enthusiasm to read them (as far as sent) preparatory to a decision.  Many things are desirable, and most worthy of commendation.  But there were some errors of fact and opinions, which I could not pass
