Roger B. Taney,
Walworth v. Kneeland — Opinion of the Court
“ He alleges in his answer that, at the time of his contract with Frisbee, and also with Arnold, there was no act of Congress which authorized them to settle on this land, or gave any right of pre emption to those who had settled on them; that they were trespassers, and had illegally combined with a large body of men of like character, who had settled upon the public lands in that district, to prevent them from selling for more than one dollar and twenty-five cents the acre, and to secure to each other at that price the land they had respectively selected. ”
