expressly made the consideration for the exercise of the authority
conferred upon the President in respect of the suspension of the
collection of foreign discriminating duties of tonnage and imposts upon
merchandise brought within the United States from Cuba and Puerto Rico
in Spanish vessels by said section 4228 of the Revised Statutes, which
section reads as follows:

SEC. 4228. Upon satisfactory proof being given to the President by the
government of any foreign nation that no discriminating duties of
tonnage or imposts are imposed or levied in the ports of such nation
upon vessels wholly belonging to citizens of the United States, or upon

Madrid, February 13, 1884, and in contravention thereof, as well as of
the provisions of the said section 4228 of the Revised Statutes, higher

ports upon certain produce, manufactures, or merchandise imported into
said ports from the United States or from any foreign country in vessels
of the United States than is imposed and levied on the like produce,
manufactures, or merchandise carried to said ports in Spanish vessels:

Now, therefore, I, Grover Cleveland, President of the United States of
America, in execution of the aforesaid section 4228 of the Revised
Statutes, do hereby revoke the suspension of the discriminating customs
imposed and levied in the ports of the United States on th
