1891, entitled "An act to amend Title LX, chapter 3, of the Revised
Statutes of the United States, relating to copyrights," that said act
"shall only apply to a citizen or subject of a foreign state or nation
when such foreign state or nation permits to citizens of the United
States of America the benefit of copyright on substantially the same
basis as its own citizens, or when such foreign state or nation is a
party to an international agreement which provides for reciprocity in
the granting of copyright, by the terms of which agreement the United
States of America may at its pleasure become a party to such agreement;"
and

Whereas it is also provided by said section that "the existence of
either of the conditions aforesaid shall be determined by the President
of the United States by proclamation made from time to time as the
purposes of this act may require;" and

Whereas satisfactory official assurances have been given that in
Portugal the law permits to citizens of the United States the benefit of
copyright on substantially the same basis as to the subjects of
Portugal:

Now, therefore, I, Grover Cleveland, President of the United States of
America, do declare and proclaim that the first of the conditions
specified in section 13 of the act of March 3, 1891, now exists and is
fulfilled in respect to the subjects of Portugal.

In testimony whereof I have hereunto set my hand and caused the seal of
the United States to be affixed.
