Washington, January 12, 1801.

Dear Sir,—Your favor of July 14th, with the papers accompanying it, came safely to hand about the last of October. That containing remarks on the line of demarcation I perused according to your permission, and with great satisfaction, and then enclosed to a friend in Philadelphia, to be forwarded to its address. The papers addressed to me, I took the liberty of communicating to the Philosophical Society. That on the language by signs is quite new. Soon after receiving your meteorological diary, I received one of Quebec; and was struck with the comparison between -32 and 19¾ the lowest depression of the thermometer at Quebec and the Natchez. I have often wondered that any human being should live in a cold country who can find room in a warm one. I have no doubt but that cold is the source of more sufferance to all animal nature than hunger, thirst, sickness, and all the other pains of life and of death itself put together. I live in a temperate climate, and under circumstances which do not expose me often to cold. Yet when I recollect on one hand all the sufferings I have had from cold, and on the other all my other pains, the former preponderate greatly. What then must be the sum of that evil if we take in the vast proportion of men who are obliged to be out in all weather, by land and by sea, all the families of beasts, birds, reptiles, and even the vegetable kingdom! for that too has life, and where there is life there may be sensation. I remark a rainbow of a great portion of the circle observed by you when on the line of demarcation. I live in a situation which has given me an opportunity of seeing more than the semicircle often. I am on a hill five hundred feet perpendicularly high. On the west side it breaks down abruptly to the base, where a river passes through. A rainbow, therefore, about sunset, plunges one of its legs down to the river, five hundred feet below the level of the eye on the top of the hill. I have twice seen bows formed by the moon. They were of the color of the common circle round the moon, and were very near, being within a few paces of me in both instances. I thank you for the little vocabularies of Bedais, Tankawis and Teghas. I have it much at heart to make as extensive a collection as possible of the Indian tongues. I have at present about thirty tolerably full, among which the number radically different, is truly wonderful. It is curious to consider how such handfuls of men, came by different languages, and how they have preserved them so distinct. I at first thought of reducing them all to one orthography, but I soon become sensible that this would occasion two sources of error instead of one. I therefore think it best to keep them in the form of orthography in which they were taken, only noting whether that were English, French, German, or what. I have never been a very punctual correspondent, and it is possible that new duties may make me less so. I hope I shall not on that account lose the benefit of your communications. Philosophical vedette at the distance of one thousand miles, and on the verge of the terra incognito of our continent, is precious to us here. I pray you to accept assurances of my high consideration and esteem, and friendly salutations.

TO COLONEL BURR.

Washington, February 1, 1801.

Dear Sir,—It was to be expected that the enemy would endeavor to sow tares between us, that they might divide us and our friends. Every consideration satisfies me you will be on your guard against this, as I assure you I am strongly. I hear of one stratagem so imposing and so base that it is proper I should notice it to you. Mr. Munford, who is here, says he saw at New York before he left it, an original letter of mine to Judge Breckenridge, in which are sentiments highly injurious to you. He knows my hand writing, and did not doubt that to be genuine. I enclose you a copy taken from the press copy of the only letter I ever wrote to Judge Breckenridge in my life: the press copy itself has been shown to several of our mutual friends here. Of consequence, the letter seen by Mr. Munford must be a forgery, and if it contains a sentiment unfriendly or disrespectful to you, I affirm it solemnly to be a forgery; as also if it varies from the copy enclosed. With the common trash of slander I should not think of troubling you; but the forgery of one's handwriting is too imposing to be neglected. A mutual knowledge of each other furnishes us with the best test of the contrivances which will be practised by the enemies of both.

Accept assurances of my high respect and esteem.

TO GOVERNOR M'KEAN.

Washington, February 2d, 1801.

Dear Sir,—I have long waited for an opportunity to acknowledge the receipt of your favor of December the 15th, as well as that by Dr. Mendenhall. None occurring, I shall either deliver the present to General Muhlenburg or put it under cover to Doctor Wistar, to whom I happen to be writing, to be sent to your house in Philadelphia, or forwarded confidentially to Lancaster.

The event of the election is still in dubio. A strong portion in the House of Representatives will prevent an election if they can. I rather believe they will not be able to do it, as there are six individuals of moderate character, any one of whom coming over to the republican vote will make a ninth State. Till this is known, it is too soon for me to say what should be done in such atrocious cases as those you mention of federal officers obstructing the operation of the State governments. One thing I will say, that as to the future, interferences with elections, whether of the State or General Government, by officers of the latter, should be deemed cause of removal; because the constitutional remedy by the elective principle becomes nothing, if it may be smothered by the enormous patronage of the General Government. How far it may be practicable, prudent or proper, to look back, is too great a question to be decided but by the united wisdom of the whole administration when formed. Our situation is so different from yours, that it may render proper some differences in the practice. Your State is a single body, the majority clearly one way. Ours is of sixteen integral parts, some of them all one way, some all the other, some divided. Whatever may be decided as to the past, they shall give no trouble to the State governments in future, if it shall depend on me; and be assured, particularly as to yourself, that I should consider the most perfect harmony and interchange of accommodations and good offices with those governments as among the first objects.
