Mr. SITGREAVES, in answer to the gentleman last up, said he would reverse his question, and ask what evidence he had to prove that these men are not freemen; can he prove they are slaves? They have stated that a law has been made in North Carolina with a view to affect their case, and bring them again into a worse slavery than before; they want to know whether they cannot obtain relief by their application to the Government of the United States. Under these circumstances, Mr. S. wished to know why their petitions should not be taken into consideration? Was there any thing in these men, he asked, that should prevent every kind of assistance being bestowed on them? Had they not an equal right to be heard with other petitioners? He hoped the House would not only give them a hearing, but afford them all the consolation of which their unfortunate case was susceptible. If the House were obliged, through a want of power to extend to the case, to object compliance with the prayers, yet, he hoped it would be done with all due tenderness; before hearing them, he thought it would be exceedingly unjust to decide. These people may produce documents sufficient to obtain favorable attention; therefore, it was impossible before they were heard to conceive whether the House could constitutionally grant relief or not. He could see no impropriety in referring it; the object of referring a case, was to inquire into facts; thus, the committee prepared the way for discussion in the House; and why the House should refuse to deliberate and discuss this case, he knew not. Mr. HEATH was clearly convinced these people were slaves, and therefore hoped their petition would lie on the table. He would remind the gentleman that, if they undertook this business, they would soon have petitions enough of the same kind, and public business would be thereby prevented. It appeared to him to be more within the jurisdiction of the Legislature of that State; indeed, the United States had nothing to do with it. Mr. MADISON said, he should be sorry to reject any petition whatever, in which it became the business of the House to attend; but he thought this case had no claim on their attention. Yet, if it did not come within the purview of the Legislative body, he thought, it might be suffered to lie on the table. He thought it a judicial case, and could obtain its due in a Court of Appeal in that State. If they are free by the laws of North Carolina, they ought to apply to those laws, and have their privilege established. If they are slaves, the constitution gives them no hope of being heard here. A law has been passed to prevent the owners of those slaves emancipating them; it is therefore impossible that any relief can be granted. The petitioners are under the laws of North Carolina, and those laws cannot be the interpreters of the laws of the United States.
