ates had to make all needful rules for the government of the
territories, the District of Columbia, the forts and other property
under national authority; so it was compelled to determine whether
slavery should exist in the places subject to its jurisdiction. Upon
Congress was also conferred the power of admitting new states; whenever
a territory asked for admission, the issue could be raised as to whether
slavery should be sanctioned or excluded. Under the Constitution,
provision was made for the return of runaway slaves; Congress had the
power to enforce this clause by appropriate legislation. Since the
control of the post office was vested in the federal government, it had
to face the problem raised by the transmission of abolition literature
through the mails. Finally citizens had the right of petition; it
inheres in all free government and it is expressly guaranteed by the
first amendment to the Constitution. It was therefore legal for
abolitionists to present to Congress their petitions, even if they asked
for something which it had no right to grant. It was thus impossible,
constitutionally, to draw a cordon around the slavery issue and confine
the discussion of it to state politics.

There were, in the second place, economic reasons why slavery was
inevitably drawn into the national sphere. It was the basis of the
planting system which had direct commercial relations with the North and
European countries; it was affected by federal laws respecting tariffs,
bounties, ship subsidies, banking, and kindred matters. The planters of
the South, almost without exception, looked upon the protective tariff
as a tribute laid upon them for the benefit of Northern industries. As
heavy borrowers of money in the North, they were generally in favor of
"easy money," if not paper currency, as an aid in the repayment of their
debts. This threw most of them into opposition to the Whig program for a
United States Bank. All financial aids to American shipping they stoutly
resisted, preferring to rely upon the cheaper service rendered by
English shippers. Internal improvements, those substantial ties that
were binding the West to the East and turning the traffic from New
Orleans to Philadelphia and New York, they viewed with alarm. Free
homesteads from the public lands, which tended to overbalance the South
by building free states, became to them a measure dangerous to their
interests. Thus national economic policies, which could not b
