The existence of two accounts of the same expedition is unusual--indeed, unique. Despite personal controversies the two narratives complement each other. Each brings out detail omitted by the other. _Luís Antonio Argüello to Governor Pablo Vicente de Sola_ San Francisco, May 26, 1817 Consequent upon the orders which I received officially from you on April 11, ultimo, I accompanied the Reverend Father Fray Narciso Duran on the expedition which at the request of the said Reverend Father Duran you authorized, and which was carried out. His diary, although I have abstracted it in brief form so that you may take into consideration all the distance we have covered, you will nevertheless use, as appears most convenient to you for the purposes you have in mind. We explored these, and other lands which up till the present have been considered unknown, swarming with heathen who are overwhelmed with error and who are without the least knowledge of God, who has placed us under the conquering banner of the most Catholic and pious monarch of all those who rule in our universe, our dearly beloved sovereign and Lord, Ferdinand the Seventh. This is with the sole object of propagating our holy religion and for which pious purpose I am ready to sacrifice my comfort and my life and all the power of my mind. With regard to this expedition which has just been completed, although you intended, as I understood according to the content of your eminent official letter, that outstanding results were to be expected, nevertheless in my opinion although the outcome was in no way unfavorable, neither was it of much value. Despite the fact that I had wished at least to make a careful survey and compile a detailed account I found myself completely prevented from accomplishing this. The reason was that I soon saw myself unable to direct my own going and coming. In consequence, since I was not able to operate according to my own wishes so as to give Your Excellency an exact account of all those lands and heathen tribes, I declined to formulate a document which could at any time be protested as defective for lack of exact and fully detailed examination of the country. I did nothing else but go where the Reverend Father Fray Narciso Duran wanted to go, and since my orders specified only that I should accompany him it seemed to me, in order to maintain harmonious relations, that I had to follow the desires of the Reverend Father mentioned. I felt that this was your intention and wish, for the expedition was organized upon the request of the said Reverend Father Duran. Thus, although I curbed my propensity to explore, it seemed to me proper to compose a day-by-day account, of which I make an exact copy.[35]
