mob--that is, by disciplined soldiers.

The sheriff, if so opposed, may call upon the Governor of the
State for military assistance. How efficient it will prove will,
of course, depend on the discipline of the militia and the
firmness of its commanding officers. It is seldom that it fails
to restore order, if the men carry loaded guns and are directed
to fire at the first outbreak of forcible resistance.

But the Governor may refuse to comply with the sheriff's request.
In such case, the execution of the process of the court fails
because of want, not of power, but of the will to exercise it on
the part of those on whom that duty rests. In every government
constituted by a distribution of the supreme authority between
different departments, each of them must do its part loyally with
respect to the others, or the whole scheme, for the time being,
breaks down.

In the United States this danger is doubly great because of the
interdependence of the general government and the particular
States. Judicial process may issue from a State court against
those who oppose its execution under claim of authority from the
United States; or from a federal Court against those who oppose
its execution under claim of authority from a State. Some
instances of such conflicts of jurisdiction have been already
mentioned.[Footnote: Chap. X.]

When the Supreme Court of the United States reverses a judgment
of a State court, it can either[Footnote: U. S. Revised Statutes,
Sec. 709.] itself render the judgment which the State court ought
