25th. Returned to Michilimackinack, at a quarter past one o'clock, A.M., from my trip to the north, for the appraisal of the Indian improvements.
31st. According to observations kept, the average temperature of the month of August (lat. 42°) was 69.16 degrees. Last year the average temperature of the same month was sixty-five degrees. The average temperature of the entire summer of 1838 was 70.85; while that of the summer of 1837 was but 65.48. Our lakes must sink with such a temperature, if the comparative degree of heat has been kept up in the upper lakes during the year.
Sept. 4th. Troops arrive at Fort Mackinack to attend the payments.
An officer of the army, who has spent a year or so in Florida, and has just returned to Michigan, says: "I have seen much that was well worth seeing, am much wiser than I was before, and am all the better contented with a lot midway of the map. The climate of Florida, during the winter, was truly delicious, but the summers, a part of one of which I saw and felt, are uncomfortable, perhaps more so than our winters. This puts the scales even, if, it do not incline the balance in our favor. The summer annoyances of insects, &c., are more than a counterbalance for our ice and snow, especially when we can rectify their influences by a well-warmed house."
6th. A literary friend in Paris writes: "I send a box to Detroit to-day, to the address of Mr. Trowbridge. It contains, for you, upwards of 200 coins, among which is one Chinese, and the rest ancient. You must busy yourself in arranging and deciphering them. I send you, also, some specimens, one from the catacombs of Paris, others from the great excavations of Maestricht, where such large antediluvian remains have been found, also relics from the field of Waterloo. The petrifactions are from Mount Lebanon."
Mr. Palfrey writes in relation to the expected notice of Stone's "Brant," but my engagements have not permitted me to write a line on the subject.
10th. Dr. John Locke, of Ohio, announces the discovery in Adams County, in that State, of the remains of an antique fort, supposed to be 600 years old. It is on a plateau 500 feet above Brush Creek, and is estimated at 800 to 1000 feet above the Ohio at low water. It is covered by soil, forest, and trees. Some of the trees in the vicinity are twenty-one feet in diameter. He infers the age from a large chestnut in the enclosure. His data would give A.D. 1238, as the date of the abandonment. We must approach the subject of our western antiquities with great care and not allow hasty and warm fancies to run away with us.
12th. A communication from Mr. Rafn informs me that the Royal Society of Antiquaries of Copenhagen, Denmark, have honored me by enrolling my name as one of its members.
12th. Congress publishes a statement submitted by the Indian Bureau, showing, 1. That upwards of fifty treaties have been concluded with various tribes since Jan. 1, 1830, for their removal to the west, in accordance with the principles of the organic act of May 28th, 1830. 2. That by these treaties 109,879,937 acres of land have been acquired. 3. That the probable value of this land to the United States is $137,349,946. 4. That the total cost of these cessions, including the various expenses of carrying the treaties into effect, is $70,059,505.
13th. Major Chancy Bush, Assistant to Major Garland, the Disbursing Agent, arrives with funds to make the annuity payments.
