Philadelphia, December 31, 1797.

Dear Sir,—Mr. Tazewell has communicated to me the inquiries you have been so kind as to make, relative to a passage in the "Notes on Virginia," which has lately excited some newspaper publications. I feel, with great sensibility, the interest you take in this business, and with pleasure, go into explanations with one whose objects I know to be truth and justice alone. Had Mr. Martin thought proper to suggest to me, that doubts might be entertained of the transaction respecting Logan, as stated in the "Notes on Virginia," and to inquire on what grounds that statement was founded, I should have felt myself obliged by the inquiry; have informed him candidly of the grounds, and cordially have co-operated in every means of investigating the fact, and correcting whatsoever in it should be found to have been erroneous. But he chose to step at once into the newspapers, and in his publications there and the letters he wrote to me, adopted a style which forbade the respect of an answer. Sensible, however, that no act of his could absolve me from the justice due to others, as soon as I found that the story of Logan could be doubted, I determined to inquire into it as accurately as the testimony remaining, after a lapse of twenty odd years, would permit, and that the result should be made known, either in the first new edition which should be printed of the "Notes on Virginia," or by publishing an appendix. I thought that so far as that work had contributed to impeach the memory of Cresap, by handing on an erroneous charge it was proper it should be made the vehicle of retribution. Not that I was at all the author of the injury; I had only concurred, with thousands and thousands of others, in believing a transaction on authority which merited respect. For the story of Logan is only repeated in the "Notes on Virginia," precisely as it had been current for more than a dozen years before they were published. When Lord Dunmore returned from the expedition against the Indians, in 1774, he and his officers brought the speech of Logan, and related the circumstances of it. These were so affecting, and the speech itself so fine a morsel of eloquence, that it became the theme of every conversation, in Williamsburg particularly, and generally, indeed, wheresoever any of the officers resided or resorted. I learned it in Williamsburg, I believe at Lord Dunmore's; and I find in my pocket-book of that year (1774) an entry of the narrative, as taken from the mouth of some person, whose name, however, is not noted, nor recollected, precisely in the words stated in the "Notes on Virginia." The speech was published in the Virginia Gazette of that time, (I have it myself in the volume of gazettes of that year,) and though it was the translation made by the common interpreter, and in a style by no means elegant, yet it was so admired, that it flew through all the public papers of the continent, and through the magazines and other periodical publications of Great Britain; and those who were boys at that day will now attest, that the speech of Logan used to be given them as a school exercise for repetition. It was not till about thirteen or fourteen years after the newspaper publications, that the "Notes on Virginia" were published in America. Combating, in these, the contumelious theory of certain European writers, whose celebrity gave currency and weight to their opinions, that our country from the combined effects of soil and climate, degenerated animal nature, in the general, and particularly the moral faculties of man, I considered the speech of Logan as an apt proof of the contrary, and used it as such; and I copied, verbatim, the narrative I had taken down in 1774, and the speech as it had been given us in a better translation by Lord Dunmore. I knew nothing of the Cresaps, and could not possibly have a motive to do them an injury with design. I repeated what thousands had done before, on as good authority as we have for most of the facts we learn through life, and such as, to this moment, I have seen no reason to doubt. That any body questioned it, was never suspected by me, till I saw the letter of Mr. Martin in the Baltimore paper. I endeavored then to recollect who among my contemporaries, of the same circle of society, and consequently of the same recollections, might still be alive; three and twenty years of death and dispersion had left very few. I remembered, however, that General Gibson was still living, and knew that he had been the translator of the speech. I wrote to him immediately. He, in answer, declares to me, that he was the very person sent by Lord Dunmore to the Indian town; that, after he had delivered his message there, Logan took him out to a neighboring wood; sat down with him, and rehearsing, with tears, the catastrophe of his family, gave him that speech for Lord Dunmore; that he carried it to Lord Dunmore; translated it for him; has turned to it in the Encyclopedia, as taken from the "Notes on Virginia," and finds that it was his translation I had used, with only two or three verbal variations of no importance. These, I suppose, had arisen in the course of successive copies. I cite General Gibson's letter by memory, not having it with me; but I am sure I cite it substantially right. It establishes unquestionably, that the speech of Logan is genuine; and that being established, it is Logan himself who is author of all the important facts. "Colonel Cresap," says he, "in cold blood and unprovoked, murdered all the relations of Logan, not sparing even my women and children; there runs not a drop of my blood in the veins of any living creature." The person and the fact, in all its material circumstances, are here given by Logan himself. General Gibson, indeed, says, that the title was mistaken; that Cresap was a Captain, and not a Colonel. This was Logan's mistake. He also observes, that it was on another water of the Ohio, and not on the Kanhaway, that his family was killed. This is an error which has crept into the traditionary account; but surely of little moment in the moral view of the subject. The material question is, was Logan's family murdered, and by whom? That it was murdered has not, I believe, been denied; that it was by one of the Cresaps, Logan affirms. This is a question which concerns the memories of Logan and Cresap; to the issue of which I am as indifferent as if I had never heard the name of either. I have begun and shall continue to inquire into the evidence additional to Logan's, on which the fact was founded. Little, indeed, can now be heard of, and that little dispersed and distant. If it shall appear on inquiry, that Logan has been wrong in charging Cresap with the murder of his family, I will do justice to the memory of Cresap, as far as I have contributed to the injury, by believing and repeating what others had believed and repeated before me. If, on the other hand, I find that Logan was right in his charge, I will vindicate, as far as my suffrage may go, the truth of a Chief, whose talents and misfortunes have attached to him the respect and commiseration of the world.

I have gone, my dear Sir, into this lengthy detail to satisfy a mind, in the candor and rectitude of which I have the highest confidence. So far as you may incline to use the communication for rectifying the judgments of those who are willing to see things truly as they are, you are free to use it. But I pray that no confidence which you may repose in any one, may induce you to let it go out of your hands, so as to get into a newspaper: against a contest in that field I am entirely decided. I feel extraordinary gratification, indeed, in addressing this letter to you, with whom shades of difference in political sentiment have not prevented the interchange of good opinion, nor cut off the friendly offices of society and good correspondence. This political tolerance is the more valued by me, who consider social harmony as the first of human felicities, and the happiest moments, those which are given to the effusions of the heart. Accept them sincerely, I pray you, from one who has the honor to be, with sentiments of high respect and attachment, dear Sir, your most obedient, and most humble servant.

[41] Has the world as yet produced more than two poets, acknowledged to be such by all nations? An Englishman only reads Milton with delight, an Italian, Tasso, a Frenchman, the Henriade; a Portuguese, Camoens; but Homer and Virgil have been the rapture of every age and nation; they are read with enthusiasm in their originals by those who can read the originals, and in translations by those who cannot.

[42] There are various ways of keeping truth out of sight. Mr. Rittenhouse's model of the planetary system has the plagiary application of an Orrery; and the quadrant invented by Godfrey, an American also, and with the aid of which the European nations traverse the globe, is called Hadley's quadrant.

[43] In a later edition of the Abbé Raynal's work, he has withdrawn his censure from that part of the new world inhabited by the Federo-Americans; but has left it still on the other parts. North America has always been more accessible to strangers than South. If he was mistaken then as to the former, he may be so as to the latter. The glimmerings which reach us from South America enable us to see that its inhabitants are held under the accumulated pressure of slavery, superstition and ignorance. Whenever they shall be able to rise under this weight, and to show themselves to the rest of the world, they will probably show they are like the rest of the world. We have not yet sufficient evidence that there are more lakes and fogs in South America than in other parts of the earth. As little do we know what would be their operation on the mind of man. That country has been visited by Spaniards and Portuguese chiefly, and almost exclusively. These, going from a country of the old world remarkably dry in its soil and climate, fancied there were more lakes and fogs in South America than in Europe. An inhabitant of Ireland, Sweden, or Finland would have formed the contrary opinion. Had South America then been discovered and settled by a people from a fenny country, it would probably have been represented as much drier than the old world. A patient pursuit of facts, and cautious combination and comparison of them, is the drudgery to which man is subjected by his Maker, if he wishes to attain sure knowledge.

[45] At Paris, in 1753, the mercury in Reaumur's thermometer was at 30½ above zero, and in 1776, it was at 16 below zero. The extremities of heat and cold therefore at Paris, are greater than at Williamsburg, which is in the hottest part of Virginia.
