15th day. At ten o’clock in the morning we set out from the wharf at the port and stopped at Angel Island because the tide was running out.[17] At about four in the afternoon the tide turned and was favorable. We set out, arrived at the Point of the Huchiunes, and stopped on the south side of that point. We went during the entire day about five hours, all at the oar in a calm sea. Angel Island, the Point of the Huchiunes, and that of the Abastos form a bay equal in size to that of the Port.[18] It contains eight islands, most of which are small. One of them, which has to be passed in navigating to the Point of the Huchiunes, has a sand bar, and it is necessary to pass a little away from it to the west. It is recognizable only when a bearing is taken. The west side [of the island] is covered with trees.

16th day. We set out from the above-mentioned Point of the Huchiunes, which we called Point San Pablo. Where we slept is a fairly good beach with water and firewood where one may stop. This Point San Pablo has opposite to it another point which we called San Pedro and halfway between are two little islands. From one point to the other will be about twice the distance as from the fort to the other shore.[19] These two points enclose the bay which we have mentioned, and form another, much larger, which we estimated to extend four leagues. From the center to the periphery this bay is square. On the northern side and the western it has five villages, which are still heathen. On the western side is a cove, according to the Indians quite large, but Ensign Gabriel Moraga has twice reached its head in the expeditions he has carried out in these parts.

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.

In this branch of the river, as in all the others which we have seen, we observed that when the tide rises, the water in some places comes up to a height of a vara and a half, and this is quite to be expected on account of the flatness of the land and the thrust of the sea through the Carquinez Strait. The channel of the river over which we traveled today has a width of a quarter of a league and in places somewhat more.

We cruised today somewhere near eight hours, four of them with a fresh breeze, and we measured about eighteen leagues, all to the east, with the river turning now and again to the northeast. We stopped at an island which has trees of some thickness but which is choked with underbrush, and it is evidently submerged during floods.

A little before reaching this island the river divides into two branches. From the mouth some alders are visible at half a league distance to the left. This is the entrance which should be taken at this island. The place where we stopped was recognized as a fishing location of the Ompines, for there were signs of campfires.[28]

18th day. We set out from this island at seven o’clock in the morning, and went back half a league so as to enter the previously mentioned river mouth (although it seems to me that it is not necessary to go back, but rather to follow the same entrance for we afterwards saw that they [the two river mouths] joined each other, a thing which even the guide had not yet noticed). We traveled about seven leagues to the east, with a fresh north wind. The river makes some turns at about one-quarter of the seven-league distance and forms another island with the opening[29] where we slept. This is why I said that it is not necessary to turn back. Everything is tule swamp on each side, with an occasional bush. The channel, as has been stated, is about a quarter of a league wide. At noon we [stopped and] landed in a swamp. Here the river widens considerably and there is another opening, which, although somewhat concealed, communicates with the River of the North.[30] The latter goes up to the left and is the one we took on the 24th on the down trip.

We set out at two o’clock in the afternoon. At about half a league we took the opening to the right, which is the one carrying less water and with some small trees, leaving the one on the left, which is the main stream, for we always tried to stay as close as we could to the mainland of San José. But if others come after us, they should follow the main river, because all the other openings lead to branches which leave it [the main river] and return to it, forming an infinity of islands.[31] We cruised to the south, but there are so many twists and windings that at times we circled the compass. The principal turns are south and southwest, and the course follows this way twice, but the banks are covered with nothing but tule, and so high that one sees nothing but sky, water, and tule. We kept on till eleven o’clock in the evening because there was no place to stop, and slept in the boats. There is land but it is flooded. [The stream] has a depth of 8 to 14 varas and a width of 80 varas, although in some places it widens, as at the turns and bends. At about nine o’clock at night the river divided into two parts, and that which we left goes on to join the big river [Río Grande] which we encountered on the 22nd. It carries more water than the one we followed, and the two join a little before the place where we set up the cross. We did not measure the distance we traveled on account of the bends and turns made by the river.[32]
