_24th day._ At dawn we found ourselves on approximately the same parallel as that where we were at the start of the trip of the 22nd. At eight o'clock we arrived at the place called "Los Meganos"[34] opposite the Julpunes. Here we ate breakfast. At noon we started out to meet the Commandant in the Strait of the Chupcanes [Carquinez Strait], which we reached at six o'clock in the afternoon. There we met the gentleman mentioned, he having got there in the morning. The region traversed this afternoon is the mouth of the San Joaquin, and it must be crossed at high tide because it contains a shoal on which boats run aground. The difference noticed between the Sacramento River and the San Joaquin is that the latter carries a smaller volume of water, although in some places it is wider. All that we have passed is nothing but pure tule swamp, without a tree under which the wanderer will find shade or a stick of wood with which to warm himself. On the other hand, the Sacramento, when it is not flooded, has dry land on both banks, with groves of trees as before described, and seems to carry a greater volume of water. We covered during the preceding night and during the day twenty leagues north, northwest, and west. _25th day._ At dawn of this day of the Pentecost Mass was sung and thereafter again the Praefacio so that during the next two days Mass should not be lacking. We set out at nine o'clock with a headwind. It was quite hard navigating through the whole strait, which will be about two leagues long and one half, more or less, wide. After leaving the strait the sea was fair and at three o'clock in the afternoon we arrived at a place called Olegario Point near Angel Island. Here we stopped after having traveled some ten leagues toward the southwest. _26th day._ At two o'clock in the morning, before the tide had finished going out, we passed the narrow entrance of the harbor, arriving almost by dawn at the beach of the Presidio. After having said Mass at the latter place we returned to the Mission of Our Father San Francisco with all good fortune, thanks to the Lord, to whom be the Glory forever and ever, Amen. Fr. Narciso Duran (rubric) _Luís Argüello's Report_ The second report of the expedition to the delta is a document whose title page states that it is a letter to the Governor, Don Pablo Vicente de Sola, and "incorporates" a diary of the expedition, which was "in company with Frays Narciso Duran and Ramón Abella." The account is signed by Luís Antonio Argüello and was undoubtedly written by him. The style indicates that the letter incorporates a revision or abstract of Argüello's diary rather than an actual copy of it (see the introduction to the letter).
