At one and a half leagues we encountered another point which we called San Andres.[20] Between the latter and Point San Pablo, all of which is the mainland of San José,[21] there is a cove which ends in a creek. The latter, according to those who have traveled past it, and according to the Indians, is like that of the town [San José] but runs very deep, and has a fair amount of trees. Between the points there are 4 varas of water, which drops to 2. This is while cruising some distance from the shore; farther in it deepens, the same as at the port [of San Francisco], because there is a channel which carries a considerable current. All the land of the Huchiunes is quite bare, although there are some oaks. As far as Carquinez Strait, with what we covered yesterday and today, we will have consumed some eight hours all to the northeast, one-quarter north from the mission. Here, within the eight leagues,[22] the bay proper ends. The strait is formed by an island[23] and the mainland of San José. The island soon ends and mainland remains on each side. The strait runs southeast and makes a half-turn to the south and has a strong current, according to the rise and fall of the tide. This strait is about two and one-half leagues long and one-quarter of a league wide, although in some places rather wider, and ends in the land of the Chupunes, for there it opens out. At this place we stopped at eleven-thirty o'clock on a little beach, which at low tide remains dry and where the boats have to pull back about 200 varas so as not to run aground. At low tide there is visible a rock, which is covered by the water and could damage boats approaching the shore. However, a little farther down, toward the mountain, there is a kind of small stream which is good [for anchorage]. To this place we gave the name "La División." It has a large pool of water and considerable firewood. Here we stopped for the night uneventfully. The shore opposite the mainland of San José on the strait called Carquinez is very bare country.[24] _17th day._[25] We set forth at nine o'clock in the morning, and as soon as we emerged from the strait at the point which, as I have said, we called "La División," we entered a large bay four or five leagues wide. Gradually from here the water becomes sweet. We cruised close to the coast of San José, and at five leagues[26] the estuary begins to develop. We traveled the whole day as close as possible to the coast of San José. There are various islands covered with tule rushes and thickets. At fourteen leagues[27] the rivers begin to form, with tule on the banks. It is sheer swamp, which prevents any landing on firm ground.
