We in the two boats then set out together but after having sailed four miles the launch "Josefina" took a southerly course up the San Joaquin while I kept on to the northwest. I soon put about to the north, taking a channel which, according to the Indian pilot, was an arm of the river which connected with the Sacramento. We sailed up this channel and at five miles descried a crowd of Indians in the tules at the edge of the river. Immediately I had all the Indian sailors jump ashore to see if they could catch a few [of the natives], whom they quickly reported to be the Christian fugitives. We could not get out of the boat because everywhere was a swamp. The sailors pursued them a good stretch but, since the fugitives had a great advantage, they [the sailors] could not catch anyone. However, they captured good booty, because the Christian fugitives, in order better to escape, abandoned everything. The sailors, very happy with the putian (which is what they call pillage in their language), reëmbarked and we continued our voyage. Going on upstream we observed that the river narrowed a great deal, so much indeed that when I tried to turn around, we found ourselves in such a narrow spot, with the current so rapid and strong, that I resolved to go back, even with great effort, as soon as I could. But we had to sail once more for about seven miles to the north. Then, taking a northwesterly direction through another slough which we encountered, we sailed about ten miles, at the end of which we turned north and entered the main stream of the Sacramento River. At seven o'clock in the evening we halted for the night on the same island.[38] At six o'clock in the morning of the following day, the 23rd, we started out to the north and at five miles bore east, following the bend of the river. We sailed on about seven miles and stopped around eleven o'clock on account of the excessive heat and because we wanted to cut a pole to provide a mast for the boat and replace the mainmast which broke off on the 15th. All this island is covered with an abundance of wood and we were entirely without any.
