hem but to hunt for Christians,
they were pacified. We pointed out to them that we had punished
the others because they had fought with us. Then we returned to
the first village with the Christians and Gentiles and there
assembled all those who had been concealed in the three
rancherias. Having separated out all those we had caught and
were taking with us, we set forth on our return journey. The
Gentiles had been cautioned, the same as the preceding ones,
that we did not wish to injure them if they did not harm us. We
followed our course of retirement along the coast. We reached an
arroyo with little water and much timber, in which we passed the
night with sentinels in the camp and at two advanced posts.

July 17. At night we reached an arroyo which has much water,
much timber and firewood, and also has nearby redwood, and very
much good sand and some very long valleys.

July 18. We reached Mission San Jose at a distance of six
leagues.

Amador's diary helps us to estimate the location and numbers of the
tribal groups in question. After leaving Mission San Jose in the
evening, his party traveled till dawn. Since all the men were mounted,
this means a probable rate of 4 miles an hour for at least six hours, or
24 miles. The following day, "in the evening," they reached the first
rancheria of the Sacalanes. Allowing a ride of three hours, the total
distance would be 36 miles. Since there is no mention of the coast, the
route must have been the well-known inland trail through Pleasanton and
Dublin. Hence the destination was in the Walnut Creek-Lafayette area.
This effectually disposes, I think, of any possibility that the
Sacalanes could have inhabited the Livermore Valley.

Further evidence is provided by subsequent events. After spending
presumably several hours subduing the Sacalanes, Amador went over near
the beach where he spent "all day," obviously meaning the rest of the
day. Probably no more than three or four hours were consumed in the
actual ride, or a distance of 9 to 12 miles. It must be remembered that
now Amador was burdened with captives, who traveled on foot at a likely
rate of no more than 3 miles per hour. Hence he must have reached the
bay shore in the vicinity of Richmond.

At nightfall, the party went on to the rancheria of the Juchillones,
which may have been a few miles up the coast. No indication is given of
distance, except that
