But there is another point worthy of notice. The word _comisionado_ used by Peña--the past participle, employed here as a noun, of the verb "to commission"--has usually been translated "commissioner," and hence it has often been urged by American writers, that he did not agree to receive a minister. But by good fortune we have a definition of that word from a Mexican secretary of relations. "A _comisionado_," wrote Bocanegra, "is a person charged by any community, or private citizen to conduct any business," and this definition obviously included ministers. On comparing the documents we find _minister_, _envoy_, _plenipotentiary_ and _comisionado_ used as equivalents; and Peña called Slidell a _comisionado_ after learning that he came as a resident minister. Besides, the title signified nothing substantial, for the parties agreed that our agent should have full powers to discuss the whole business in hand, and so it follows again that, for the purpose of settling all the points of difference existing between the two nations, Mexico agreed to receive an American minister. November 6 Polk heard as much through Commodore Conner, then off Vera Cruz; and three days later Parrott arrived with Peña's autograph note, which was similarly understood at the White House.[4.22] For good reasons the President felt that no time could be wasted. It was a critical juncture. The controversy with England over the possession of Oregon had reached an acute stage, and our minister at London expressed the opinion that she was trying to make use of Mexico in connection with it. Our relations with Mexico had dragged long enough. If it is intended to do anything, a New York merchant had written some time since to the secretary of the navy, "no time should be lost in sending a person to Mexico, as you can scarcely conceive the feverish excitement in our mercantile community," due to the dread of privateers. Herrera's pacific administration was tottering; and our consul at Vera Cruz warned the state department to act promptly, since it might go down at any time. Paredes, the monarchist, was known to be plotting a revolution; and the London _Times_, then a journal of great importance, had pronounced emphatically for a Spanish throne in Mexico as a bulwark against the United States, and had said that it believed no European power would object. We had promised through Black that a minister would be despatched "immediately," if he would be received; and Peña not only had made no objection to this, but had shown impatience for his arrival. In anticipation of satisfactory news from our consul, Slidell had been ordered to Pensacola, and instructions for him drafted. By ten o'clock in the evening of November 10 these were ready; Polk signed his commission; and Lieutenant Lanier of the navy set out at once for Pensacola with the documents.[4.23] [SLIDELL'S INSTRUCTIONS]
