During the afternoon the party traveled from the vicinity of Crockett "two leagues east along the top of the hills close to the water, and one east-southeast up the canyon which had some oaks and other trees, by which we again came out at the top of the hills near the water." According to Bolton (1930, IV: 375n), this point was on the bluffs just west of Martinez.

The implication of Anza's account and the rather specific statement by Font seem to support Crespi's description. There was little oak or other type of woody plant on the south shore west of what is now Port Costa. From there to Martinez the canyons held a fair growth of oak. In those areas not bearing oak, the primary plant cover was grass. Neither Crespi nor Anza nor Font gives any hint of the heavy infiltration of shrubby vegetation, such as Baccharis, poison oak, or other chapparal species, which now extend down the entire slope of the hills from Crockett to Martinez. The deduction is reasonable, although strict proof is lacking, that the modern vegetation has entered the region since 1775.

On this day Anza and Font made the acquaintance of two new species of fish, the sturgeon and the salmon, good descriptions of which are recorded by both explorers. Furthermore, the day was notable for encounters with the natives. Shortly after breaking camp the Spaniards were met by ten Indians who invited them to the nearby village (which Bolton says was at Tormey, about 2 miles west of Crockett). This village was large; Font estimated the population as 400 persons and Anza as 500. Font's account (F2) of his visit is long and circumstantial, but its value for ethnographic detail is such that it merits reproduction in full:

Their method of welcoming us was like this: at sunrise the ten Indians came, one behind another, singing and dancing. One carried the air, making music with a little stick, rather long and split in the middle, which he struck against his hand and which sounded something like a castanet. They reached the camp and continued their singing and dancing for a little while. Then they stopped dancing, all making a step in unison, shaking the body and saying dryly and in one voice, "Ha, ha, ha!" Next they sat down on the ground and signalled to us that we must sit down also. So we sat down in front of them, the commander, I, and the commissary. Now an Indian arose and presented the commander with a string of cacomites, and again sat down. Shortly afterward he rose again and made me a present of another string of cacomites, and again sat down. In this way they went making us their little presents, another Indian giving me a very large root of chuchupate which he began to eat, telling me by signs that it was good.

This compliment being over, they invited us to go to their village, indicating that it was nearby. The commander consented to give them this pleasure, and at once we began to travel. They followed after us with their singing and dancing.... After going a short distance we came to the village, which was in a little valley on the bank of a small arroyo, the Indians welcoming us with an indescribable hullabaloo. Three of them came to the edge of the village with some long poles with feathers on the end, and some long and narrow strips of skin with the hair on, which looked to me like rabbit skin, hanging like a pennant, this being their sign of peace. They led us to the middle of the village where there was a level spot like a plaza, and then began to dance with other Indians of the place with much clatter and yelling.

A little afterward a rather old Indian woman came out, and in front of us, for we were on horseback, nobody having dismounted. She began to dance along, making motions very indicative of pleasure, and at times stopping to talk to us, making signs with her hands as if bidding us welcome. After a short while I said to the commander that that was enough. So he gave presents of glass beads to all the women, they regaled us with their cacomites, and we said goodby to everybody in order to continue on our way. They were apparently sad because we were leaving, and I was moved to tenderness at seeing the joy with which we were welcomed by those poor Indians. Their color and other qualities of nakedness, slight beard, etc., are the same as those seen hitherto, and the same as those we saw farther on. Some wear the hair long, others short, and some have beards rather long and heavy.

Font and Anza had an excellent opportunity to observe aboriginal methods of navigation and fishing. At the western end of Carquinez Strait, says Anza (A, p. 140), five tule rafts crossed the strait in less than a quarter of an hour, the tide being slack. Font says, regarding these craft (F2, p. 320):

We saw there some launches very well made of tule, with their prows or points somewhat elevated. They had been anchored near the shore with some stones for anchors, and in the middle of the water some Indians were fishing in one.... I saw that they were fishing with nets and that they anchored the launch with some very long slim poles.

These poles were measured and found to be about 13 varas long (roughly 35 ft.). Font goes on to describe the actual taking of fish:

Among other fish which they caught the Indians who were fishing pulled out two very large ones, about two varas long, and their method of catching them was this: as soon as they felt from the pull made by the fish that it was in the net, which was tied to the two poles, they began gradually to raise one of the poles, and as soon as the fish and the net came in sight, without taking it from the water they gave the fish many blows on the head. Once I counted fifteen blows in succession and in another case twenty-odd. Now that it was dead and had lost its strength they took it from the net and put it inside the launch.
