I transmit to Congress translations of two letters from Don Joaquin d'Anduaga to the Secretary of State, which have been received at the Department of State since my last message communicating copies of big correspondence with this Government. JAMES MONROE. _Don Joaquin de Anduaga to the Secretary of State_. [Translation.] PHILADELPHIA, _April 24, 1822_. SIR: As soon as the news was received in Madrid of the recent occurrences in New Spain after the arrival at Vera Cruz of the Captain-General and supreme political chief appointed for those Provinces, Don Juan O. Donojú, and some papers were seen relative to those same transactions, it was feared that for forming the treaty concluded in Cordova on the 24th of August last between the said General and the traitor, Colonel Dr. Augustine Iturbide, it had been falsely supposed that the former had power from His Catholic Majesty for that act, and in a little time the correctness of those suspicions was found, as, among other things, the said O. Donojú, when on the 26th of the same August he sent this treaty to the governor of Vera Cruz, notifying him of its prompt and punctual observance, he told him that at his sailing from the Peninsula preparation for the independence of Mexico was already thought of, and that its bases were approved of by the Government and by a commission of the Cortes. His Majesty, on sight of this and of the fatal impression which so great an imposture had produced in some ultramarine Provinces, and what must without difficulty be the consequence among the rest, thought proper to order that, by means of a circular to all the chiefs and corporations beyond seas, this atrocious falsehood should be disbelieved; and now he has deigned to command me to make it known to the Government of the United States that it is false as far as General O. Donojú published beyond his instructions, by pointing out to it that he never could have been furnished with other instructions than those conformable to constitutional principles. In compliance with this order of His Majesty, I can do no less than observe to you, sir, how unfounded one of the reasons is in your note of the 6th instant for the recognition by this Government of those of the insurgent Provinces of Spanish-America--that it was founded on the treaty made by O. Donojú with Iturbide--since not having had that power nor instruction to conclude it it is clearly null and of no value. I repeat to you, sir, the sentiments of my distinguished consideration, and pray God that you live many years. JOAQUIN DE ANDUAGA. _Don Joaquin de Anduaga to the Secretary of State_. [Translation.] PHILADELPHIA, _April 26, 1822_. JOHN QUINCY ADAMS, _Secretary of State_.
