LETTER I.

MR. DUPONCEAU TO MR. HECKEWELDER.

PHILADELPHIA, 9th January, 1816.

SIR.--As corresponding secretary to the Historical Committee of the American Philosophical Society, it is my duty to solicit the aid of men of learning and information, by the help of whose knowledge light may be thrown on the yet obscure history of the early times of the colonization of this country, and particularly of this State. Our much-respected President and common friend, Dr. Wistar, has often spoken to me of the great knowledge which you possess respecting the Indians who once inhabited these parts, and of your intimate acquaintance with their languages, habits and history. He had promised me, when you was last here, to do me the favour of introducing me to you, but the bad state of his health and other circumstances prevented it, which has been and still is to me the cause of much regret. Permit me, sir, on the strength of his recommendation, and the assurance he has given me that I might rely on your zeal and patriotic feelings, to request, in the name of the Historical Committee, that you will be so good as to aid their labours by occasional communications on the various subjects that are familiar to you and which relate to the early history of this country. Accounts of the various nations of Indians which have at different times inhabited Pennsylvania, their numbers, origin, migrations, connexions with each other, the parts which they took in the English and French wars and in the Revolutionary war, their manners, customs, languages, and religion, will be very acceptable, as well as every thing which you may conceive interesting, on a subject which at no distant period will be involved in obscurity and doubt, for want of the proper information having been given in time by those cotemporaries who now possess the requisite knowledge and are still able to communicate it. I hope, sir, that you will be able to find some moments of leisure to comply, at least in part, with this request, which you may do in any form that you may think proper. If that of occasional letters to Dr. Wistar or myself should be the most agreeable or convenient to you, you may adopt it, or any other mode that you may prefer. I beg you will favour me with an answer as soon as possible, that I may be able to inform the Committee of what they may expect from you. You may be assured that all your communications will be respectfully and thankfully received.

I am, very respectfully, Sir, Your most obedient humble servant, PETER S. DUPONCEAU, Corresponding Secretary.
