CORNPLANTER came to Philadelphia, by the way of Fort Franklin and Fort Pitt, traveling with his party down the Allegheny river in canoes. At Fort Franklin, ensign JEFFERS, of the 1st Pennsylvania regiment, was in command. He furnished our Chief with a letter of recommendation, in which he says: "The bearer hereof, CYENTWOKEE, the head Chief of the Seneca nation, is an undoubted friend of the United States. When the Indians have stolen horses and other things from our people, I have known him, with the greatest dignity, to give orders for them to be returned. I never knew his orders to be disobeyed. When the people of Cussewago (now Meadville) were about to fly on account of unfavorable reports about some of the Southern (Western) Indians, he sent a speech to me, in which he said, 'he wished the people to keep their minds easy, and take care of the corn fields, that the Six Nations were friends; that should the Western Indians invade the settlements, he would gather his warriors and help to drive them to the setting of the sun.' In consequence of this, the people rested easy. On his arrival here, he told me that should I be invaded, so that I could not get provisions, that he and his warriors would clear the way; he said that at the Council at the Muskingum the great men asked him which side he would die on? He told them on the side of the Americans. He says he is of the same mind yet. Sundry other things might be said, but as he is now on his way to attend the Assembly at Philadelphia, I will only recommend him to the particular attention of the good people of Pennsylvania, between here and that place. They may depend upon it, that they not only entertain a friend, but a friend of great consequence, for the Seneca nation is so much governed by him, that if he says _war_, it is _war_; and if he says _peace_, it is _peace_. He is, therefore, a man worthy of the greatest attention. The other Chiefs with him, second him in every thing, and are men worthy of great attention." This interesting letter was addressed "To the good people between here (Fort Franklin) and Philadelphia." It was of great service to CORNPLANTER on his journey; and when he arrived in Philadelphia, he placed it in the hands of Governor MIFFLIN. The paper is among the archives of Pennsylvania, and is endorsed "1790, recommendary letter from I. JEFFERS, ensign of the 1st Pennsylvania regiment, commanding Fort Franklin, on French creek, in favor of CYENTWOKEE, or CORNPLANTER."[Q] [Q] Pennsylvania Archives, 1790, p. 86.
