MR. MORRILL. I maintain, that, when the passenger is landed, and comes within the limits and jurisdiction of the State, and within its police power, the commercial power of the Government ceases at that point, and the treatment of the passenger thereafter is within the police power of the State exclusively. MR. SUMNER. I think the Senator goes beyond the decision of the Supreme Court. He overrules that decision. MR. MORRILL. I am precisely on a line with the License cases, in which the principle was applied to the importation of liquors. MR. SUMNER. At a certain stage, I admit, the police power of the State may intervene; but I do nevertheless insist, as beyond question, that the power of the United States is complete over every passenger vessel arriving in the harbor, so that it may be subjected to any regulations in the discretion of Congress for the public good with reference to passengers. Of course, this discretion is to be exercised wisely for the public good, that the public health may not suffer. Strange, if the National Government, which is our guardian against foreign foes, may not protect us against this fearful enemy. MR. MORRILL. I do not deny that; I agree to that. MR. SUMNER. Very well. MR. MORRILL. Now my query is, Can the power of commerce, that power which regulates the passengers on their passage to this country, follow the passengers entirely into the States and overrule the internal police of the States? That is the question. MR. SUMNER. The Senator puts a question running into that already propounded by the Senator from Iowa, and to which I was coming in due course of time. I have already arrived at it. I was illustrating the power that the Government would have in the harbor; and now let me give another illustration, familiar to my friend: it is with reference to goods. I need not remind the Senator, that, when goods arrive, subject to duties, the custom-house exercises its control, according to the prescription of law, not only while the goods are water-borne, but after they have been landed; and if they have been landed in violation of the law, it pursues them even into the interior. MR. CHANDLER. To the Rocky Mountains.
