In de Anza's diary on March 29, 1776, he wrote: "Night having fallen, at a quarter past six I went down to the arroyo of San Andreas and to another, that of San Matheo, where it descends to empty into the estuary. There I found in our camp nearly all the men of the village, very friendly, content, and joyful, putting themselves out to serve us in every way, a circumstance which I have noted in all the natives seen from the 26th up to now, but one which I had not experienced theretofore since leaving the people of the Colorado River."
