26th day. We started early toward the west and after six leagues of mountains and bad trails we reached a place formerly called El Toro, where we ate lunch, and we, with the horses, drank. In the afternoon, going in the same direction more or less for another six leagues of extremely bad trail, we arrived at dark at a little flat with some pools of good water. This place we called San Guillermo.

27th day. From San Guillermo we went six leagues in the same direction to stop for lunch at the old village of the Pateños. From here in the afternoon after five leagues to the northwest we reached this mission, in good condition, thanks be to God.

FATHER RAMÓN ABELLA’S EXPEDITION, 1811

This manuscript of twenty-seven pages is entitled: “Diario de un registro de los ríos grandes, October 15-31, 1811.” The title page bears the note:

A copy in the handwriting of and signed by Gervasio Argüello.

Exploration of the Eastern Shores of upper San Francisco Bay, San Pablo and Suisun Bays and of the lower Sacramento and San Joaquin Rivers.

The authorship of this document is something of a mystery. The copy in the Bancroft Library has the title given above but is in the handwriting of, and signed by, Gervasio Argüello, who was not a member of the expedition. If it is Father Abella’s actual diary, then how may one explain the references to “Father Ramón,” “the two priests,” etc.? Furthermore, the diction is confused and ungrammatical, unlike what one would expect of a literate priest. Certain passages give the impression of a third person who is involved. My own feeling is that Father Abella kept some sort of record but that these notes, plus a verbal account by Sergeant José Sanchez, the military commander of the expedition were worked over by Gervasio Argüello into a day-by-day account which has the semblance of a diary. Credit for the leadership of the expedition, of course, remains with Father Abella.
