Provisions 7

 12. Citizens of either state having lands in the other
 may transport the produce of such lands to their own
 state, and also remove their effects, free of any duty or
 charge.

 13. "These articles shall be laid before the legislatures
 of Virginia and Maryland, and their approbation being
 obtained, shall be confirmed and ratified by a law of each
 state, never to be repealed or altered by either without
 the consent of the other."

III. LEGISLATIVE HISTORY

 The thirteenth proviso in the Compact of 1785 was that
 "these articles shall be laid before the legislatures of Vir
 ginia and Maryland, and their approbation being obtained,
 shall be confirmed and ratified by a law of each state, never
 to be repealed or altered by either without the consent
 of the other." Accordingly, the Compact was adopted by
 ch. 1 of the Maryland Acts of 1785 and by ch. 17 of the
 Virginia Acts of 1785, being set out at length in each act.

 The enacting clause in each act confirmed the binding
 character of the Compact, in support of the provisions of
 the 13th section quoted above. Thus, the Maryland act
 stated that

. . . every article, clause, matter and thing, in the
same compact contained, shall be obligatory on this
state and the citizens thereof, and shall be forever
faithfully and inviolably observed and kept by this
government, and all its citizens, according to the true
intent and meaning of the said compact; and the faith
and honour of this state is hereby solemnly pledged
and engaged to the general assembly of the common
wealth of Virginia, and the government and citizens
thereof, that this law shall never be repealed or altered
by the legislature of this government, without the
consent of the government of Virginia.

The counterpart of this legislative declaration was contained in the Virginia act.
