At a league and a half we encountered another headland, which we called San Andres [i.e., Point Pinole]. Between the latter and that of San Pablo, all mainland of San José, is an estuary which terminates in a stream [i.e., mouth of San Pablo Creek] which, according to those who have been there and to the Indians, is like that of the pueblo, except that it is deeper and is well wooded. From one point to the other the depth of the water is four varas, becoming shallower to two, when one sails close to the shore. Farther into the bay conditions would be the same as at the port for there is a channel which carries a considerable current. This is all the land of the Huchunes. It is quite bare, although there are some oak trees. As far as the strait of the Karquines, including what we have covered yesterday and today, we must have spent about eight hours, all to the northeast, one-quarter north from the Mission. Here ends the above mentioned bay, estimated at 8 leagues. The strait is formed by an island [i.e., Mare Island] and the mainland of San José. The island soon ends and is replaced by mainland on both sides. The strait runs to the southwest and makes a half-turn to the south. It carries a heavy current, depending on the rise and fall of the tide. This strait is about two and a half leagues long and about a quarter of a league wide, in some places somewhat wider. It ends in the land of the Chupunes, where it becomes broader. Here we stopped at half-past eleven o'clock at a little beach which is dry at low tide and where the boats have to retreat 200 varas in order not to be stranded. Here at low tide is seen a rock, which otherwise is covered with water and which might damage the boats on landing. However, a little farther down toward the hill is a sort of little valley, which is good. This place we called la Division [probably at or near Martinez]. It has a large pool of water and plenty of firewood. Here we passed the night without incident. The shore of the strait of the Karquines which is opposite the mainland of San José is very barren.
