at dawn they reached their destination. The most
probable guess is that the rancheria was somewhere on the southeast
shore of San Pablo Bay between Pinole and Rodeo. This view is supported
by the account of the return trip.

After having attacked three rancherias, conducted negotiations,
identified and secured several dozen captives, Amador began his retreat
"along the coast." At night they reached a well watered arroyo, which
could have been San Pablo Creek or Wildcat Creek. On the 17th the party
spent the whole day moving down the shore to an arroyo, near some
redwoods, which, according to the notation of the following day, was 6
leagues from Mission San Jose. The arroyo which best fits the
description and the distance (about 15 mi.) is San Leandro Creek. This,
in turn, is just about a day's journey from San Pablo Creek for a
military party encumbered with numerous prisoners. There are therefore
reasonable grounds contained in Amador's diary for placing the
Juchillones on the shore of San Pablo Bay from Point San Pablo northeast
to Rodeo or beyond.

With respect to numbers, it may first be noted that Amador found three
rancherias fairly close together for each tribal group: Sacalanes and
Juchillones. The only indication of size for the Sacalanes is the
mention of 50 men and women who participated in the defense of the first
rancheria; The other two rancherias had been deserted. Perhaps a maximum
of 300 and a minimum of 100 inhabitants for all three villages is
indicated. For the Juchillones, Amador states only that the third
rancheria was "very large." This may be taken to mean a population of
over 100, and on this assumption the total might be set within the range
suggested for the Sacalanes, i.e., 100-300.

In the letter to the Governor covering his report, dated July 19 at
Mission San Jose (Bancroft Trans., Prov. St. Pap., XV: 319-320) Amador
says, regarding the Cuchillones [Juchillones] "... it is certain that
there are many rancherias and very big ones; and this is the reason why
they assemble to hold their councils and eat many seeds." This
statement would favor a fairly large population. Furthermore, in
replying to Amador on July 21, Governor Borica (Bancroft Trans., Prov.
Rec., V: 118) notes that the expedition brought back 83 Christians and 9
Gentiles. This fact shows that the two tribal groups, Sacalanes and
Juchillones, had already been able to absorb the losses occasioned by
the missionization of 40 per
