This provision authorizes Congress to delegate to the President the power to call out the militia for the purposes named, and to make his decision conclusive as to the necessity for the call. 1 The militia are "a body of armed citizens trained to military duty, who may be called out in certain cases, but may not be kept on service like standing armies, in times of peace." That is the case as to the active militia of the State. The men comprising it come from the body of the militia, and when not engaged at stated periods in drilling and other exercises, return to their usual vocations, as is usual with militia, and are subject to call when the public exigencies demand it. The word "troops" conveys the idea of an armed body of soldiers whose sole occupation is war or service, answering to the regular army. The organization of the active militia bears no likeness to such a body of men. It is simply a domestic force as distinguished from the regular troops, and is only liable to be called into service when the exigencies of the State make it necessary.2 The act of Congress of May 2, 1792, is the first leg - islation relating to the militia. Under it, and its supplements, the militia can be used to suppress rebellion against the national government. The President, who, as seen, is to judge of the exigency, may address his request either to the governor of the State or to an officer of the militia. In actual service, the militia are subject to the same rules as the regular troops. The President specifies the term of service, which may not exceed nine months. The right voluntary to associate together as a military company or organization, and to drill or to parade with arms, without, and independent of, an act of Congress or a law of the State authorizing the same, is not an attribute of national citizenship. Military organization and military drill and parade under arms are subjects especially under the control of the government of each country. They cannot be claimed as a right independent of law. Under our political system they are subject to the regulation and control of the State and Federal governments, acting in due regard to their respective prerogatives and powers.4 See Мов. the object proposed in the erection.1 See GRANT, 3; TOLL, 2. A statute of a State which authorizes any person to erect and maintain on his land a water mill and milldam upon and across any stream not navigable, paying to the owners of lands flowed damages assessed in a judicial proceeding, does not deprive such owners of their property without due process of law. The right to the use of running water is publici juris, and common to all the proprietors of the bed and banks of a stream. Each has a right to a reasonable use of the water as it flows past his land, not interfering with a like reasonable use by those above or below him. One reasonable use is the use of the power, inherent in the fall of the stream and the force of the current, to drive mills. That power cannot be used without damming up the water, and thereby causing it to flow back. If the water thus dammed up by one riparian proprietor spread over the land of others, they could at common law bring successive actions against him for the injury done them, or even have the dam abated. Before the Mill Acts, therefore, it was often impossible for a riparian proprietor to use the water-power at all, without the consent of those above him. The purpose of these statutes is to enable any riparian proprietor to erect a mill and use the water-power of the stream, provided he does not interfere with an earlier exercise by another of a like right or with any right of the public; and to substitute for the common-law remedies a new form of remedy by which any one whose land is flowed can have assessed, once for all, either in a gross sum or by way of annual damages, adequate compensation for the injury. General mill acts exist in some twenty or more States. See AQUA, Currit, etc.; NUISANCE; WATER. Miller. See MECHANIC. 2. The tenth of a cent. See COIN; M, 2.
