e difficult to decipher and do not run strictly in sequence.
Hence, for convenience, I have substituted in the legends numbers for
the Greek letters, number 1 following Z of the alphabetical series. The
use of these numbers in conjunction with the Greek letters on the map
will not be difficult. In the left-hand column is the Spanish text; in
the right-hand column, a literal translation. No attempt is made to
correlate the names given by Canizares with those applied at the present
time.

The third map (map 3) copies the second, is carefully done, and gives
essentially the same information, but varies in minor points. Canizares
remained in San Blas for several years after his visit to San Francisco.
During this period his 1776 map was apparently redrawn by Manuel
Villavicencio, in 1781, presumably under the supervision of Canizares
himself. Whether it is more accurate than the 1776 map is open to
question. Small and capital letters are used for the localities on the
map and in the legends.

The letter describing the survey of the Bay was written by Canizares and
addressed to "Senor Capitan," obviously Ayala. It was dated September 7,
1775, "en este nuebo Puerto de S. Fran^{co} al abrigo de la Isla de
Los Angeles." This document, which is an account of the first boat
trip throughout San Francisco Bay, has never, to my knowledge, been
published. Its intrinsic interest, consequently, as well as its bearing
upon primitive geography and ethnography, warrants its presentation.
A translation follows herewith. Various matters requiring comment are
discussed immediately subsequent to the translation.

_Canizares' Report_

On the four occasions when I went out to explore this port and
survey its northeastern and north-northeastern portion I
discovered what is shown on the map and is set forth here. To
the north-northeast of the Island of Los Angeles, at a distance
of one mile, there is a bay which runs north-northwest to
south-southeast. The distance across between the points which
form it is about two leagues and its length two and one-half. In
its northwestern part there are three little islets, forming
with the coast a narrow channel, which is shut off at its
southwestern mouth by a shoal. Around all the margin of the bay
are folded hills, with very few groves of trees and these which
there are consist in part of laurel and live-oak; there may be
seen in the interior t
