"When, in 1803, we acquired from France the territory known as Louisiana, it became necessary to legislate for the protection of the inhabitants residing therein. It will be seen by looking into the bill establishing the territorial government in 1805 for the territory of New Orleans, embracing the same country now known as the State of Louisiana, that the ordinance of 1787 was expressly extended to that territory, excepting the sixth section, which prohibited slavery. Then that act implied that the Territory of New Orleans was to be a slaveholding territory, by making that exception in the law. But, sir, when they came to form what was then called the Territory of Louisiana, subsequently known as the Territory of Missouri, north of the thirty-third parallel, they used different language. They did not extend the ordinance of 1787 to it at all. They first provided that it should be governed by laws made by the governor and the judges, and when, in 1812, Congress gave to that territory, under the name of the Territory of Missouri, a territorial government, the people were allowed to do as they pleased upon the subject of slavery, subject only to the limitations of the Constitution of the United States. Now, what is the inference from that legislation? That slavery was, by implication, recognized south of the thirty-third parallel; and north of that, the people were left to exercise their own judgment and do as they pleased upon the subject, without any implication for or against the existence of the institution.
