But This is a still stronger deviation from the rules of evidence than what was first attempted. To deduce an argument from a person’s usurpation of property, or their possessing themselves of lands, that they therein acted under the authority of the owner, is unfair reasoning, and might be advan*ced to sanctify any trespass whatever. Such r*noi testimony would be attended with dangerous conse- L quences, and prove highly injurious to society. We cannot possibly receive it.
