_16th_. J. D. Doty, Esq., writes from Detroit that a District Court has been established by Congress in the upper country--that he has been appointed to the judgeship, and will hold a court at Michilimackinack, on the third Monday in July. A beginning has thus been made in civil jurisdiction among us benighted dwellers on this far-off land of God's creation. He states, also, the passage of a law for claimants to lands, which have been occupied since 1812. Where law goes, civilization will soon follow.
_23d_. Giles Sanford, of Erie (Penn.), sends me some curious specimens of the concrete alum-slate of that vicinity--they are columnar, fan-shaped--and requests a description. It is well known that the presence of strong aluminous liquids in the soil of that area had a tendency to preserve the flesh on General Wayne's body, which was found undecayed when, after twenty years' burial, they removed it to Radnor church, in Philadelphia.
_28th_. Governor C. sends me a pamphlet of additional inquiries, founded chiefly on my replies, respecting the Indian languages. He says--"You see, I have given new scope to your inquiries, and added much to your labors. But it is impracticable, without such assistance as you can render me, to make any progress. I find so few--so very few--who are competent to a rational investigation of the subject, that those who are so must be loaded with a double burden."
_July 6th_. Mr. Harry Thompson, of Black Rock, N.Y., writes me that he duly forwarded, by a careful teamster, my three lost boxes of minerals, shells, &c., collected in the Wabash Valley, Missouri, and Illinois, in 1821, and that they were received by Mr. Meech of Geneva, and forwarded by him to E.B. Shearman & Co., Utica. The loss of these collections of 1821 seems to me very grievous.
_19th_. Judge Doty writes from Mackinac: "Believing the winds and fates to have been propitious, I trust you had a speedy, safe, and pleasant passage to your home. A boat arrived this morning, but I heard nothing. Mr. Morrison leaves this evening, and I forward, by him, your dictionary, with many--_many_ thanks for the use. _We_ completed the copy of it last evening, making seventy-five pages of letter paper. I hope I shall be able to return you the favor, and give you soon some _nice_ Sioux words."
