The limitations imposed by this section were designed to prevent preferences as between ports on account of their location in different States. They do not forbid such discriminations as between individual ports. Acting under the commerce clause, Congress may do many things which benefit particular ports and which incidentally result to the disadvantage of other ports in the same or neighboring States. It may establish ports of entry, erect and operate lighthouses, improve rivers and harbors, and provide structures for the convenient and economical handling of traffic.[1527] A rate order of the Interstate Commerce Commission which allowed an additional charge to be made for ferrying traffic across the Mississippi to cities on the east bank of the river was sustained over the objection that it gave an unconstitutional preference to ports in Texas.[1528] Although there were a few early intimations that this clause was applicable to the States as well as to Congress,[1529] the Supreme Court declared emphatically in 1886 that State legislation was unaffected by it.[1530] After more than a century the Court confirmed, over the objection that this clause was offended, the power which the First Congress had exercised[1531] in sanctioning the continued supervision and regulation of pilots by the States.[1532] Alaska is not deemed to be a State within the meaning of this clause.[1533] Clause 7. No Money shall be drawn from the Treasury, but in Consequence of Appropriations made by Law; and a regular Statement and Account of the Receipts and Expenditures of all public Money shall be published from time to time.
