TO CHRISTOPHER COLLES.

WASHINGTON, June 19, 1808.

SIR, I thank you for the pamphlet containing your ideas on the subject of canals constructed of wood but it is not in my power to give any definite opinion of its national importance. If there exists a cement which used as a lining for cisterns and aqueducts, renders them impermeable to water, (and it is affirmed that in France they are in the possession and use of such an one,) then it becomes the common question whether constructions of wood, brick, or rough stone are cheapest in the end? A question on which every man possesses materials for forming his judgment. I suspect it is the supposed necessity of using hewn stone in works of this kind which has had the greatest effect in discouraging their being undertaken. I tender you my salutations and respects.

TO JAMES PEMBERTON.

WASHINGTON, June 21, 1808. SIR,-Your favor of May 30th was delivered me on my return to this place, and I now enclose the prospectus of Clarkson's history with my subscription to it. I have perused with great satisfaction the Report of the Committee for the African institution. The sentiments it breathes are worthy of the eminent characters who compose the institution,

as are also the generous cares they propose to undertake. I wish they may begin their work at the right end. Our experience with the Indians has proved that letters are not the first, but the last step in the progression from barbarism to civilization. Our Indian neighbors will occupy all the attentions we may spare, towards the improvement of their condition. The four great Southern tribes are advancing hopefully. The foremost are the Cherokees, the upper settlements of whom have made to me a formal application to be received into the Union as citizens of the United States, and to be governed by our laws. If we can form for them a simple and acceptable plan of advancing by degrees to a maturity for receiving our laws, the example will have a powerful effect towards stimulating the other tribes in the same progression, and will cheer the gloomy views which have overspread their minds as to their own future. history. I salute you with friendship and great respect.

TO WALTER FRANKLIN.

WASHINGTON, June 22, 1808. Thomas Jefferson returns his thanks to Mr. Franklin for the address to the Society of Friends which he was so kind as to send him. The appeal both to facts and principles is strong, and their consistency will require an able advocate. Conscious that the present administration has been essentially pacific,

and that in all questions of importance it has been governed by the identical principles professed by that Society, it has been quite at a loss to conjecture the unknown cause of the opposition of the greater part, and bare neutrality of the rest. The hope, however, that prejudices would at length give way to facts, has never been entirely extinguished, and still may be realized in favor of another administration.

TO DOCTOR THOMAS LEIB.

WASHINGTON, June 23, 1808. SIR, I have duly received your favor covering a copy of the talk to the Tammany society, for which I thank you, and particularly for the favorable sentiments expressed towards myself. Certainly, nothing will so much sweeten the tranquillity and comfort of retirement, as the knowledge that I carry with me the good will and approbation of my republican fellow-citizens, and especially of the individuals in unison with whom I have so long acted. With respect to the federalists, I believe we think alike; for when speaking of them, we never mean to include a worthy portion of our fellow-citizens, who consider themselves as in duty bound to support the constituted authorities of every branch, and to reserve their opposition to the period of election. These having acquired the appellation of federalists, while a federal administration was in place, have not cared

about throwing off their name, but adhering to their principle, are the supporters of the present order of things. The other branch of the federalists, those who are so in principle as well as in name, disapprove of the republican principles and features of our Constitution, and would, I believe, welcome any public calamity (war with England excepted) which might lessen the confidence of our country in those principles and forms. I have generally considered them rather as subjects for a mad-house. But they are now playing a game of the most mischievous tendency, without perhaps being themselves aware of it. They are endeavoring to convince England that we suffer more by the embargo than they do, and if they will but hold out awhile, we must abandon it. It is true, the time will come when we must abandon it. But if this is before the repeal of the orders of council, we must abandon it only for a state of war. day is not distant, when that will be preferable to a longer continuance of the embargo. But we can never remove that, and let our vessels go out and be taken under these orders, without making reprisal. Yet this is the very state of things which these federal monarchists are endeavoring to bring about; and in this it is but too possible they may succeed. But the fact is, that if we have war with England, it will be solely produced by their manoeuvres. I think that in two or three months we shall know what will be the issue.

I salute you with esteem and respect.

The

TO GENERAL JAMES WILKINSON.

WASHINGTON, June 24, 1808.

Thomas Jefferson presents his compliments to General Wilkinson, and in answer to his letters of yesterday observes that during the course of the Burr conspiracy, the voluminous communications he received were generally read but once and then committed to the Attorney General, and were never returned to him. It is not in his power, therefore, to say that General Wilkinson did or did not denounce eminent persons to him, and still less who they were. It was unavoidable that he should from time to time mention persons known or supposed to be accomplices of Burr, and it is recollected that some of these suspicions were corrected afterwards on better information. Whether the undefined term denunciation goes to cases of this kind or not Thomas Jefferson does not know, nor could he now name from recollection the persons suspected at different times. He salutes General Wilkinson respectfully.

TO COLONEL DANIEL C. BRENT.

WASHINGTON, June 24, 1808. DEAR SIR,-The information given to me by Mrs. Paradise of letters to me from her grandsons, is without foundation. I have not for many years heard a tittle respecting the family at Venice. Should any information respecting them come to me I will certainly communicate it to Mrs. Paradise.
