Viva Jesus.
Diary of the expedition of exploration made in the month of May of 1817 by the Commandant of the Royal Presidio of our Father San Francisco, Lieutenant Don Luís Argüello, with his launch San Rafael, alias “The Fine One,” and by the Fathers Fray Ramón Abella, minister of the Mission of Our Father of San Francisco, and Fray Narciso Duran, minister of San José, with the launch named San José, alias “The Fisherman,” in the only two rivers which enter the Port of Our Father San Francisco, called the Sacramento and the San Joaquin.
13th day of May. We left the beach at the Presidio at ten o’clock in the morning of this day with a fresh wind, which lasted until we had crossed the entrance of the port. By rowing we arrived at twelve o’clock at the big island of Los Angeles [Angel Island], where we ate lunch. At five o’clock in the afternoon we left the island, and having passed Point San Pablo, which is on the side of the mainland of San José, we stopped at eight o’clock in the evening, having gone in the entire day six leagues toward the northeast.
14th day. We set out at six o’clock in the morning, and with a light wind we arrived at noon at the end of the strait of the Chupcanes [i.e., Carquinez Strait]. The village of this name is Christian, part at San José, part at San Francisco. It is fourteen leagues distant from the latter and seventeen leagues north-northeast of the former.
After lunch we set out with a fresh wind, which became strong by the middle of the afternoon, in the direction of the Ompines toward the east. In this area one recognizes the mouths of the only two rivers which flow through this strait to the Port: one comes from the north and northeast and is called the Sacramento, the other from the east and southeast and is called the San Joaquin. I say they are the only two rivers, for it seems that the many openings and branches which form so many islands of brush and tulares, as well also as some other rivers which are found here, all come to discharge their water into the two rivers mentioned. Thus although the western slopes of the Sierra Nevada form certain rivers, as has been stated, nevertheless all of them lose their identity and are lost in the two principal rivers just described.
In the meantime, night having approached and the boat of the Commandant having gone ahead, he stopped on the mainland of San José at the mouth of the San Joaquin. We two Fathers in the other boat followed the route agreed upon, and took the mouth of the Sacramento so as to reach the opposite shore in the land of the Ompines. However, although we passed near the other boat and saw their fire, it was not possible to go back on account of the high wind. We landed on an island of tule which was flooded when the tide rose and had to take refuge in a bramble patch to protect ourselves against the water until it went down. We spent a very difficult night, although cheerfully, and a no better one was passed by the Commandant, for, although with us it was water without fire, with him it was wind without shelter.
All this day we went twelve leagues northeast and east.
15th day. The storm lasted all night. At five o’clock in the morning the Commandant arrived to join us. He got here with the main mast broken but, the Lord be thanked, without greater misfortune. It seems almost a miracle that when it fell it did not break someone’s head or kill someone. We set out soon to search for a place suitable for saying Mass, for this was the day of the Ascension. Having gone five or six leagues up the Sacramento ahead of the same wind, we landed on dry land, where Mass was said. But because this place was very exposed and cold we set forth after lunch, in the middle of the afternoon, and arrived by dark at the end of the hills of the Ompines, the latter serving us as a shelter from the storm.[22] This place is called “Los Ciervos.” About a league before getting there the launch San José struck a submerged log, which scared us. However, on later examination, no damage was found, thank God! We went in this day eight leagues east and northeast.[23]
