WaTu as Inc ValIey OF the sacramento
and San Joaquin. In this vast plain
the sea, breeze loses its influence, and
the degree of heat in the middle of the
day. during the summer months, is
much greater than is known on the
Atlantic coast in The same lariludes.-
1t is dry, however, and probably not
more oppressive. On the foothills of
the Sierra Nevada, and especially in the
deep ravines of the streams, the ther-
mometer frequently ranges from 40
deg. to lis deg. in the shade, during
three or four hours of the day, say from
eleven until three o'clock. In the even
ing, as the sun declines, the radiation Of
hea, ceases. The cool, dry atmosphere
from the mountains spreads over the
whole country, and renders The night
cool and invigorating. .,.-,.T M
I have been kindly furnished by
Surgeon General Lawson, U. s. Army,
with the ,hermometrical observations,
taken at the following places in Cali.
fornia, viz: AT San Francisco, by As.
sistant Surgeon w. G. Parker. for six
months, embracing the last quarter. of
ls47, and the first quarter of ls4s.-
The monthly mean temperature was as
follows-October, 81 deg; November,
40 deg; December, so deg; January.
40 deg; February, 60 deg; March, 81
deg.
AT Monterey. in latitude SO deg. 35
min. North, and longitude l2l west, on
the coast, about one degree and half
South of San Francisco, by Assistant

The monthly mean temperature was:
May, So deg; June, so deg; July, SO

from the coast.
AT San Diego, latitude 80 deg; As
min, longitude west 1T deg. III min,
by Assistant Surgeon J. D. Summers,
for The following three months of 1s49,
vlz-July, monthly mean temperature.
II deg; August, rs deg: September, 10
deg,
At Suitcrsvile on the Sacramento
river, latitude 3s deg. 80 min, longitude
west, l2l deg, "a min, by Assistant
Surgeon r. Murray, for the following
months of ls49: July, monthly mean
temperature 73 deg; August, 70 deg;
September, IS deg; October, 65 deg.
These observations show o remarka-
bly, high temperature at San francisco,
during the six months from October to
March inclusive; variation of only 8
degrees in the monthly mean, and a
mean temperature for the six months
of 81 degrees.
AT Monterey we find the mean month.
ly temperature from May to November
inclusive, varying only 5 degrees, and
the mean temperature of the 7 months
10 have been So deg. If we take The
three summer months, the mean heat
was 60 degrees. The mean Of the three
winter months was little over 40 deg
showing mean difference, on the part
of the coast, of only IL deg. between
summer and winter. .... -'E..r /
The mean temperature Of San Fran.
cisco. for the three winter months, was
precisely the same as at Monterey-a
little over 40 deg.
As these cities are only abont one
degree and half distant from each
other, and both, situated near the ocean.
the temperature at both, in summer,
may very reasonably be supposed to be
as nearly similar, as the thermometer
shows il to be in winter. ....
The mean temperature of July, An.
gnst and September al San Diego, only
8 deg. SO min, south of Monterey, was
To deg. The mean iemperoiure of the
same months at Monterey was little
over SO deg; showing mean difference
of Is degrees. ...-..5
This would seem TO indicate that The
cold ocean current is thrown off from
the southern part of the coast by Point
Conception. and The islands south of il;
and consequently, its influence on the
climate of San Diego is much less than
at Monterey and San Francisco.
At Los Angeles, forty miles distant
from the coast, the mean temperature
Of the three months was IA deg; of the
three autumn months 67 deg; of the
three winter months 81.
Al Suttersville, about one hundred
and thirty miles from the oceen, and
four degrees northof Los Angeles, the
mean temperature of August, Seplem-
Der and October, was 81 degrees. The
mean temperature of the same months
al Monterey was SO deg; showing
