del Norte," "del Este," "del Sur." Of
these the first three are evidently local and in the region now being
discussed: (1) the redwoods back of Oakland and San Leandro; (2) Alameda
Creek and adjacent plain; (3) the shore of the Bay directly west of the
mission. The conversions, 1797-1802 inclusive, from these three areas
were respectively 31, 170, 130, indicating that San Francisco and Santa
Clara had by no means completed the conquest.

_Area 2. The coast from Richmond to Carquinez Strait._--That this strip
was held by the tribal group known as Huchiun (Cuchillones, Juchillones)
has been supported by the accounts of Amador (diary of 1797) and of
Abella (diary of 1811). The latter writer, it will be remembered,
renamed the Point of the Huchines, Point San Pablo, a name which it
retains today. The point of the Abastos or Aguastos became
Point San Pedro. The Abastos, it may be pointed out, were neither
Costanoan nor resident on the east side of the Bay. They lived on the
Bay shore of Marin County, as is abundantly evident from the San
Francisco baptism records.

The Huchiun are mentioned by Chamisso and by Choris (Mahr, 1932) in
1816, jointly with various other North Bay tribes. Chamisso says that
the Utschiun, together with the Guyment, Olumpalic, Soclan, and Sonomi,
all speak the same language, a manifest error. Choris repeats the
mistake. Arroyo de la Cuesta gives a Huichun vocabulary and says (1837;
MS p. 21) "Karquin and Huichun is one language--Saclan is another,
entirely distinct." The Huchiun are noted in the San Francisco records
first in 1787 (Tuchiun) and subsequently repeatedly until 1809, although
they never appear in the San Jose record. Apparently San Jose derived
converts from the east rather than from up coast.

The exact limits of the Huchiun are doubtful. Amador spent a night
somewhere near Richmond and then went north to find them. Abella
associates them closely with Point San Pablo, and implies that their
land reached as far as the strait. We may tentatively draw their
boundary between Rodeo and Crockett.

_Area 3. Carquinez Strait and Concord Valley._--We are dealing here with
the shore line from Crockett through Martinez nearly to Pittsburg, and
inland between Concord and Pacheco. The principal Indian name associated
with this area is Karquin, from which the strait takes its name. Just
what group of people is involved is a puzzling question.
