The word "territory," according to Worcester, "means land, country, a district of country under a temporary Government." The words "territory or other property," as used, do imply, from the use of the pronoun other, that territory was used as descriptive of land; but does it follow that it was not used also as descriptive of a district of country? In both of these senses it belonged to the United States—as land, for the purpose of sale; as territory, for the purpose of government.

But, if it be admitted that the word territory as used means land, and nothing but land, the power of Congress to organize a temporary Government is clear. It has power to make all needful regulations respecting the public lands, and the extent of those "needful regulations" depends upon the direction of Congress, where the means are appropriate to the end, and do not conflict with any of the prohibitions of the Constitution. If a temporary Government be deemed needful, necessary, requisite, or is wanted, Congress has power to establish it. This court says, in McCulloch v. The State of Maryland, (4 Wheat., 316,) "If a certain means to carry into effect any of the powers expressly given by the Constitution to the Government of the Union be an appropriate measure, not prohibited by the Constitution, the degree of its necessity is a question of legislative discretion, not of judicial cognizance."

The power to establish post offices and post roads gives power to Congress to make contracts for the transportation of the mail, and to punish all who commit depredations upon it in its transit, or at its places of distribution. Congress has power to regulate commerce, and, in the exercise of its discretion, to lay an embargo, which suspends commerce; so, under the same power, harbors, lighthouses, breakwaters, &c., are constructed.

Did Chief Justice Marshall, in saying that Congress governed a Territory, by exercising the combined powers of the Federal and State Governments, refer to unlimited discretion? A Government which can make white men slaves? Surely, such a remark in the argument must have been inadvertently uttered. On the contrary, there is no power in the Constitution by which Congress can make either white or black men slaves. In organizing the Government of a Territory, Congress is limited to means appropriate to the attainment of the constitutional object. No powers can be exercised which are prohibited by the Constitution, or which are contrary to its spirit; so that, whether the object may be the protection of the persons and property of purchasers of the public lands, or of communities who have been annexed to the Union by conquest or purchase, they are initiatory to the establishment of State Governments, and no more power can be claimed or exercised than is necessary to the attainment of the end. This is the limitation of all the Federal powers.

But Congress has no power to regulate the internal concerns of a State, as of a Territory; consequently, in providing for the Government of a Territory, to some extent, the combined powers of the Federal and State Governments are necessarily exercised.

If Congress should deem slaves or free colored persons injurious to the population of a free Territory, as conducing to lessen the value of the public lands, or on any other ground connected with the public interest, they have the power to prohibit them from becoming settlers in it. This can be sustained on the ground of a sound national policy, which is so clearly shown in our history by practical results, that it would seem no considerate individual can question it. And, as regards any unfairness of such a policy to our Southern brethren, as urged in the argument, it is only necessary to say that, with one-fourth of the Federal population of the Union, they have in the slave States a larger extent of fertile territory than is included in the free States; and it is submitted, if masters of slaves be restricted from bringing them into free territory, that the restriction on the free citizens of non-slaveholding States, by bringing slaves into free territory, is four times greater than that complained of by the South. But, not only so; some three or four hundred thousand holders of slaves, by bringing them into free territory, impose a restriction on twenty millions of the free States. The repugnancy to slavery would probably prevent fifty or a hundred freemen from settling in a slave Territory, where one slaveholder would be prevented from settling in a free Territory.

This remark is made in answer to the argument urged, that a prohibition of slavery in the free Territories is inconsistent with the continuance of the Union. Where a Territorial Government is established in a slave Territory, it has uniformly remained in that condition until the people form a State Constitution; the same course where the Territory is free, both parties acting in good faith, would be attended with satisfactory results.

The sovereignty of the Federal Government extends to the entire limits of our territory. Should any foreign power invade our jurisdiction, it would be repelled. There is a law of Congress to punish our citizens for crimes committed in districts of country where there is no organized Government. Criminals are brought to certain Territories or States, designated in the law, for punishment. Death has been inflicted in Arkansas and in Missouri, on individuals, for murders committed beyond the limit of any organized Territory or State; and no one doubts that such a jurisdiction was rightfully exercised. If there be a right to acquire territory, there necessarily must be an implied power to govern it. When the military force of the Union shall conquer a country, may not Congress provide for the government of such country? This would be an implied power essential to the acquisition of new territory. This power has been exercised, without doubt of its constitutionality, over territory acquired by conquest and purchase.

And when there is a large district of country within the United States, and not within any State Government, if it be necessary to establish a temporary Government to carry out a power expressly vested in Congress—as the disposition of the public lands—may not such Government be instituted by Congress? How do we read the Constitution? Is it not a practical instrument?

In such cases, no implication of a power can arise which is inhibited by the Constitution, or which may be against the theory of its construction. As my opinion rests on the third section, these remarks are made as an intimation that the power to establish a temporary Government may arise, also, on the other two grounds stated in the opinion of the court in the insurance case, without weakening the third section.
