of words which has already received authoritative interpretation.
We cannot disregard the fact that the Constitution of the
Commonwealth was framed by a Convention of Representatives
from the several colonies. We think that, sitting here, we
are entitled to assume - what, after all, is a fact of public
notoriety - that some, if not all, of the framers of that Con-
stitution were familiar, not only with the Constitution of the
United States, but with that of the Canadian Dominion and
those of the British colonies. When, therefore, under these cir-
cumstances, we find embodied in the Constitution provisions
undistinguishable in substance, though varied in form, from pro-
visions of the Constitution of the United States which had long
since been judicially interpreted by the Supreme Court of that
Republic, it is not an unreasonable inference that its framers
intended that like provisions should receive like interpretation.
We should be prepared, therefore, if it were necessary, and if we
found ourselves unable otherwise to come to a clear conclusion,
to accept the doctrines laid down in the judgment of the Supreme
Court of the United States, delivered by Marshall, C.J., in
McCulloch's Case, in 1819 (and since that time often spoken of by
that Court as axiomatic), as applicable to the interpretation of the
Constitution of the Commonwealth. "The people of a State
give to their government a right of taxing themselves and their
property, and, as the exigencies of government cannot be limited,
they prescribe no limits to the exercise of this right, resting con-
fidently on the interest of the legislator, and on the influence of
the constituents over their representative, to guard them against
its abuse. But the means employed by the government of the
Union have no such security, nor is the right of a State to tax
them sustained by the same theory. Those means are not given
by the people of a particular State, not given by the constituents
of the legislature, which claims the right to tax them, but by the
people of all the States. They are given by all, for the benetit of
all; and, upon theory, should be subjected to that government
only which belongs to all. It may be objected to this definition,
that the power of taxation is not confined to the people and
property of a State. It may be exercised upon every object
