was given the power to make provision for
citizen-soldiers as follows:--

Section 8, Clause 15. _To provide for calling forth the militia to
execute the laws of the Union, suppress insurrections and repel
invasions._

Clause 16. _To provide for organizing, arming and disciplining the
militia, and for governing such part of them as may be employed in the
service of the United States, reserving to the States respectively the
appointment of the officers, and the authority of training the militia
according to the discipline prescribed by Congress._

Number of the Militia.--All able-bodied male citizens of the United
States and males between eighteen and forty-five years of age who have
declared their intention to become citizens are regarded as the militia
force of the country. As a matter of fact, there are at present only
about 100,000 men enrolled in this service. But in the case of an
emergency the President may compel the governors of the various States
to furnish the troops needed. The militia may thus be called into
service, under their own State officers, for a period of nine months.
The War of 1812 and the Civil War furnish the best illustrations of the
enforcement of this provision.

Volunteers of 1898.--We should note here the manner in which
men were secured for the war against Spain. We see, according to
Clause 15, that the militia may be called out only for the purposes
of executing the laws of the Union, suppressing insurrections, and
repelling invasions. Now, in the case given, the war was to be
conducted in foreign territory, and President McKinley called for
200,000 volunteers. It was understood, however, that preference
would be given to those volunteers who were already members of the
organized militia.

V. LOCATION OF THE CAPITAL.

Section 8, Clause 17. _Congress shall have the power to exercise
exclusive legislation in all cases whatsoever over such district (not
exceeding ten miles square) as may, by cession of particular States and
the acceptance of Congress, become the seat of the government of the
United States, and to exercise like authority over all places purchased
by the consent of the legislature of the State in which the same shall
be, for the erection of forts, magazines, arsenals, dock-yards and other
needful buildings._

One of the most interesting contests in American history arose in the
selection of a site for the capital city
