I am happy, however, that at length we have a Minister at Madrid; I am persuaded, that this will contribute vastly to opening the eyes both of France and Spain. I shall be always obliged to you for intelligence, especially concerning your progress in your affair. I am, with much esteem, dear Sir, your servant, JOHN ADAMS. * * * * * TO THE PRESIDENT OF CONGRESS. Paris, May 13th, 1780. Sir, The answer of the King of France to the declaration of the Empress of Russia is as follows, dated April 25th, 1780. "The war in which the King finds himself engaged, having no other object than the attachment of his Majesty to the principles of the liberty of the seas, he could not but see with a true satisfaction the Empress of Russia adopt this same principle, and show herself resolved to maintain it. That which her Imperial Majesty requires of the belligerent powers, is nothing more than the rules already prescribed to the French marine, the execution of which is supported with an exactness that is known and applauded by all Europe. "The liberty of neutral vessels, restrained in a small number of cases only, is a direct consequence of the law of nature, the safeguard of nations, the solace even of those, who are afflicted with the scourge of war; thus the King has desired to procure, not only to the subjects of the Empress of Russia, but to those of all the States who have embraced a neutrality, the liberty of navigating upon the same conditions, which are announced in the declaration to which his Majesty answers this day.
