On leaving the hall, whither he came to see me out, he said: "I am seventy-eight, and (assuming a gayer vein) in a good state of preservation." He was then a little bent, but preserved in conversation the vivacity of his prime. He had, I think, been a man of about five feet ten or eleven inches. His accent and tone of voice are decidedly French. His eye, which is black and penetrating, kindled up readily. He wore a black silk cap to hide baldness.

15th. A singular coincidence of the names and ages of Indian chiefs, is shown in the following notice from a Russian source:--

"We have just received from Nova Archangesk, an account of the death of the chief of one of the most powerful tribes of North America, Black Hawk, who was suddenly carried off on the banks of the River Moivna, in the seventy-first year of his age. The loss of this chief, who kept up friendly relations with the authorities of the Russian colony, and was always hostile to the English, is felt in a lively manner by the Russian government, who rested great hopes on the influence exercised by Black Hawk, not only over his own tribe, but also over all the neighboring nations. The Czar has ordered the new governor-general of the Russian colony in America to endeavor by all means to secure the friendship of the three sons of Black Hawk, the eldest of whom, now forty-eight years of age, has succeeded his father in the government of the tribe."--Le Commerce.

22d. I left New York on the 12th, in the cars, with Mrs. Schoolcraft and the children, for Washington, stopping at the Princeton depot, and taking a carriage for Princeton. I determined to leave my son at the Round Hill School, in charge of Mr. Hart, and the next day went to Philadelphia, where I accepted the invitation of Gen. Robert Patterson to spend a few days at his tasteful mansion in Locust street. I visited the Academy of Natural Sciences, and examined Dr. Samuel George Morton's extensive collection of Indian crania. While here, I placed my daughter in the private school of the Misses Guild, South Fourth Street. I attended one of the "Wistar parties" of the season, on the 15th, at Mr. Lea's, the distinguished bookseller and conchologist, and reached the city of Washington on the 21st, taking lodgings at my excellent friends, the Miss Polks.

24th. Submitted an application to the department for expending a small part of the Indian education fund, for furthering the general object, by publishing, for the use of teachers and scholars, a compendious dictionary, and general grammar of the Indian languages.

25th. In a conference with Mr. Murray, of Pennsylvania, a recent commissioner to adjust Indian claims at Prairie du Chien, Wisconsin, he gave me Mr. Robert Stuart's testimony respecting the Indian trade, to read. It appears from the document that the gain on trade of the American Fur Company, from 1824 to 1827, was $167,000. From 1827 to 1834 it was $195,000. From the aggregate of ten years' business, there is to be deducted $45,000, being a loss from 1817 to 1824, which leaves a profit on seventeen years' trade of $317,000.

Mr. Murray presented me a copy of the Commissioner's report. These claims have not yet received the action of the department. The commissioners set out with requiring of traders high evidence of the individual indebtedness by Indians. They finally decided that the Winnebago debts were national. They went further--they approved and adopted the decision of a meeting of the claimants themselves, as to the application to individual firms, of the fund. This decision was subsequently sanctioned by eight Winnebago chiefs, who were stated to be authorized to act for the nation.

The error, in all these cases, seems to be, that where a tribe has agreed to set apart a generic sum to satisfy debts, and the United States has accepted the trusteeship of determining the individual shares, that the Indians, who cannot read, or write, or understand figures, or accounts at all, and cannot possibly tell the arithmetical difference between one figure and another, should yet be made the subject of these minor appeals. The TRUSTEE himself should determine that, by such testimony as he approves, and not appear to seek to bolster up the decisions of truth and faithfulness, by calling on Indian ignorance and imbecility, which is subject to be operated on by every species of selfishness.

25th. I applied to the department this day, by letter, for leave of absence from my post on the frontier, to visit Europe.

26th. I called on Mr. Poinsett, the Secretary of War, and received from him the permission which I had yesterday solicited. I also called on the President (Mr. Van Buren), who, in turning the conversation to the state of disturbances on the frontier, evinced the deepest interest that neutrality should be preserved, and asked me whether the United States Marshal at Detroit had faithfully performed his duty.
