pations of the federal government, we get into
an unfathomable abyss, and fairly put ourselves out of the reach of all
reasoning. Imagination may range at pleasure till it gets bewildered
amidst the labyrinths of an enchanted castle, and knows not on which
side to turn to extricate itself from the perplexities into which it has
so rashly adventured. Whatever may be the limits or modifications of the
powers of the Union, it is easy to imagine an endless train of possible
dangers; and by indulging an excess of jealousy and timidity, we may
bring ourselves to a state of absolute scepticism and irresolution. I
repeat here what I have observed in substance in another place, that all
observations founded upon the danger of usurpation ought to be referred
to the composition and structure of the government, not to the nature
or extent of its powers. The State governments, by their original
constitutions, are invested with complete sovereignty. In what does our
security consist against usurpation from that quarter? Doubtless in the
manner of their formation, and in a due dependence of those who are to
administer them upon the people. If the proposed construction of the
federal government be found, upon an impartial examination of it, to be
such as to afford, to a proper extent, the same species of security, all
apprehensions on the score of usurpation ought to be discarded.

It should not be forgotten that a disposition in the State governments
to encroach upon the rights of the Union is quite as probable as a
disposition in the Union to encroach upon the rights of the State
governments. What side would be likely to prevail in such a conflict,
must depend on the means which the contending parties could employ
toward insuring success. As in republics strength is always on the side
of the people, and as there are weighty reasons to induce a belief that
the State governments will commonly possess most influence over them,
the natural conclusion is that such contests will be most apt to end to
the disadvantage of the Union; and that there is greater probability of
encroachments by the members upon the federal head, than by the federal
head upon the members. But it is evident that all conjectures of this
kind must be extremely vague and fallible: and that it is by far the
safest course to lay them altogether aside, and to confine our attention
wholly to the nature and extent of the powers as they are delineated in
the Constitution. Ev
