Tecumseh

Any sale not made by all is not valid. The late sale is bad. It was made by a part only. Part do not know how to sell. It requires all to make a bargain for all. All red men have equal rights to the unoccupied land. The right of occupancy is as good in one place as in another. There can not be two occupations in the same place. The first excludes all others. It is not so in hunting or traveling; for there the same ground will serve many, as they may follow each other all day; but the camp is stationary, and that is occupancy. It belongs to the first who sits down on his blanket or skins which he has thrown upon the ground; and till he leaves it no other has a right.

Tecumseh to Governor Harrison (August 1810).
