_My Children_,--By late arrangements with France and Spain, we now take their place as your neighbors, friends, and fathers; and we hope you will have no cause to regret the change. It is so long since our forefathers came from beyond the great water, that we have lost the memory of it, and seem to have grown out of this land, as you have done. Never more will you have occasion to change your fathers. We are all now of one family, born in the same land, and bound to live as brothers; and the strangers from beyond the great water are gone from among us. The Great Spirit has given you strength, and has given us strength; not that we might hurt one another, but to do each other all the good in our power. Our dwellings, indeed, are very far apart, but not too far to carry on commerce and useful intercourse. You have furs and peltries which we want, and we have clothes and other useful things which you want. Let us employ ourselves, then, in mutually accommodating each other. To begin this on our part, it was necessary to know what nations inhabited the great country called Louisiana, which embraces all the waters of the Mississippi and Missouri, what number of peltries they could furnish, what quantities and kind of merchandize they would require, where would be the deposits most convenient for them, and to make an exact map of all those waters. For this purpose I sent a beloved man, Captain Lewis, one of my own household, to learn something of the people with whom we are now united, to let you know we were your friends, to invite you to come and see us, and to tell us how we can be useful to you. I thank you for the readiness with which you have listened to his voice, and for the favor you have showed him in his passage up the Missouri. I hope your countrymen will favor and protect him as far as they extend. On his return we shall hear what he has seen and learnt, and proceed to establish trading houses where our red brethren shall think best, and to exchange commodities with them on terms with which they will be satisfied. With the same views I had prepared another party to go up the Red River to its source, thence to the source of the Arkansas, and down it to its mouth. But I will now give orders that they shall only go a small distance up the Red River this season, and return to tell us what they have seen, and that they shall not set out for the head of that river till the ensuing spring, when you will be at home, and will, I hope, guide and guard them in their journey. I also propose the next year to send another small party up the river of the Kansas to its source, thence to the head of the river of the Panis, and down to its mouth; and others up the rivers on the north side of the Missouri. For guides along these rivers, we must make arrangements with the nations inhabiting them.
