rish and so truly the interest
of both to maintain.

By the first section of an act of Congress passed on the 13th of July,
1832, the tonnage duty on Spanish ships arriving from the ports of Spain
was limited to the duty payable on American vessels in the ports of
Spain previous to the 20th of October, 1817, being 5 cents per ton. That
act was intended to give effect on our side to an arrangement made with
the Spanish Government by which discriminating duties of tonnage were to
be abolished in the ports of the United States and Spain on the vessels
of the two nations. Pursuant to that arrangement, which was carried into
effect on the part of Spain on the 20th of May, 1832, by a royal order
dated the 20th of April, 1832, American vessels in the ports of Spain
have paid 5 cents per ton, which rate of duty is also paid in those
ports by Spanish ships; but as American vessels pay no tonnage duty
in the ports of the United States, the duty of 5 cents payable in our
ports by Spanish vessels under the act above mentioned is really a
discriminating duty, operating to the disadvantage of Spain. Though no
complaint has yet been made on the part of Spain, we are not the less
bound by the obligations of good faith to remove the discrimination,
and I recommend that the act be amended accordingly. As the royal order
above alluded to includes the ports of the Balearic and Canary islands
as well as those of Spain, it would seem that the provisions of the act
of Congress should be equally extensive, and that for the repayment of
such duties as may have been improperly received an addition should be
made to the sum appropriated at the last session of Congress for
refunding discriminating duties.

As the arrangement referred to, however, did not embrace the islands of
Cuba and Puerto Rico, discriminating duties to the prejudice of American
shipping continue to be levied there. From the extent of the commerce
carried on between the United States and those islands, particularly the
former, this discrimination causes serious injury to one of those great
national interests which it has been considered an essential part of our
policy to cherish, and has given rise to complaints on the part of our
merchants. Under instructions given to our minister at Madrid, earnest
representations have been made by him to the Spanish Government upon
this subject, and there is reason to expect, from the friendly
disposition which is entertained toward this co
