These were the only Indians with whom I had communication in this northern part. Following said channel a distance to the west from its mouth, there is a harbor, so commodious, accessible, abundant in fresh water and wood, and sheltered from all winds, that I considered it one of the best inland ports that our Sovereign has for anchoring a fleet of vessels. I called it Puerto de la Asumpta, having examined it the day of the festivity of that saint[76]. To the southeast of this port[77] the canon continues, until it joins the channel of the Indian village. Following a distance of three leagues in an east-northeast direction, it enters another bay[78] with a depth of thirteen brazas, diminishing to four where some rivers[79] empty and take the saltiness of the water which there becomes sweet, the same as in a lake. The rivers come, one from the east-northeast (this is the largest, about two hundred and fifty yards wide), the other, which has many branches, comes from the northeast through tulares and swamps in very low land, the channels not over two brazas with sandy bars at their mouths, where I found in sounding the water not more than a half braza. This made me think they were not navigable, especially as on the second occasion I entered them, I touched bottom both in the channels and on the bars. The bay where these rivers empty, is another port larger than the Asumpta, where any vessel may enter, but it would be difficult to obtain wood, which is far from the shore. All the eastern coast is covered with trees; that to the west is arid, dry, full of grasshoppers, and impossible of settlement. This is all I have reconnoitered to the north of Angel Island. To the southeast of said island following the estero is as follows: To the east of this island, at a distance of about two leagues, there is another, steep and barren, without any shelter, which divides the mouth of the channel in two[80], through which the sea enters to a distance of about twelve leagues. The width of this channel is in some parts, one, two, and three leagues; its depth is not over four brazas, its width ample, but a pistol shot outside of the channel; its depth is not over two brazas. The extreme end of this sound, eastward, forms with a point, a pocket, which, at low tide is nearly dry[81]. In every part there are seen poles driven in (the mud), with black feathers, bunches of tule, and little shells, which I believe are buoys for fishing, since they are in the water. I think it will be impossible to anchor for three leagues inside of this slough, because it is so exposed to the weather that strong cables and good anchorage are needed to hold against the strong current from the north.
