mosphere of the Atlantic, at much lower

temperature.
As the sun rises from day to day week,
alter week, and month after month, in un-
clouded brightness during the dry, season
and pours down hi. unbroken rays on the
dry, unprotected surface of the country.
the heat becomes so much greater inland
than it Is on the ocean, that an under cur
rent Of cold air Bringing the fog with /:
rushes over the coast range of hills. and
through their numerous passes, toward.
the INTERIOR -
Every day, as the heat, inland, aitains
a sufficient temperature, The cold, dry
wind from the ocean commences to blow.
This is usually from eleven TO one o'clock;
and as the day advances the wind in
creases and continues TO blow, Till late at
night. When the vacuum is filed, or the
equilibrium of the tmosphere restored,
the wind ceases; perfect calm prevails
until about the same hour the following
day, when the same process commences
and progresses as before; and these phe-
nomena are of daily occurrence, with few
exceptions, throughout the dry season.
These cold winds and fogs render ths
climate at San Francisco and all along tho
coast OF California, except the extreme
southern portion Of it, probably more UNI
comfortable TO these not accustomed to it,
in summer than in winter
A few miles inland, where the heat OF
the sun modties and softens the wind
from the ocean, the climate j. moderate
and delightful. The heat in the middle
Of the day is not SO great as to retaid Ia
Dor, or render exercise in the open air
uncomfortable. The nights are cool and
pleasant. This description of climate pre-
walls in all the valleys along The coast
range, and extends throughout the coun-
try, north and south, as far eastward az
the valley 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 latitudes. 1t is dry, however, and
probably not more oppressive. On the
foot of the Sierra Nevada, and es-
pecially in the deep ravines Of the streams,
the thermometer frequently ranges from
ll0' to ll5' in the shade, during three or
four hours of the day, say from eleven
until three o'clock. In the evening, aa
the sun declines, the radiation Of heat
ceases. The cool, dry atmosphere from
the mountains spreads over the whole
country, and renders the nights cool and
inrigoraiing.
I have been kindly furnished by Surgeon General
Lawson, u S. army, with thermometrical observa-
tons, taken at the following places in California.
viz: At San Francisco, by Assistant Surgeon W. C.
Parker, for six months, embracing the last quarter
OF lsa5, and the hrst quarter Of is4s The monthly
mean temperature was as follows october, 81 deg.
Nov, 40 deg; December, so dag; January, ~ der:
February. 80 deg; March, 81 deg.
AT Noaterey,in latitude % deg. 3s min. north and
longitude 12l west, the coast, about one degree
and half south of San Francisco, by Assistant Sur
geon w. s. King, for seven months from May to
! November inclusive. The monthly mean tempera-
ture was: May, 90 deg; June, So deg; July, e.:
| August. 50 deg; september, Js deg; October, 50

At Los Angeles, latitude - deg. min., longi-
| tude west IS deg. min.. by Assistant Surgeon
John 5. Griffin: for ten months-from June, is47, to
! March, iS43, inclusive. The monthly mean tenn
peraure was: June, 73 deg; July, ~ August rs
! September, IS; October, SO; November, SO De-
cember, 60; January, 5s; February, 55; March, es
deg. This place about forty miles from the coast
At San Diego. latitude 80 deg. 45 mn., longit1ds
west III deg II min-, by Assistant surgeon J. ID.
Summers, for the following three months Of fS4s,
viz: july monthly mean temperature, II deg; Au-
gust, 10 deg; September, 20 deg.
At Su'tersville, the Sacramento river, latitude
35 deg. 81 min. north. longitude west l2i der. "a
uiin. hy Assistant Surgeon II. Murray, for the fol
lowing months Of 1919: July, monthly mean tenn
perature 7s Geg; August, 20; September, e5; oc-
tOker &c deg.
These observations show remarkably high tenn
pefa'ure at San francisco during the six months
from October to March inclusive a variation Of
only eight degrees in the monthly mean, and a mesn
temperature for the six months OF 81 deg.
AT Monterey we find the mean monthly tempers-
ture from May to November inclusive, varying only
SIX degree and the mean temperature OF the seven
months to have been SIS deg. If we take the three
summer months, The mean heat was co aeS.f The
mean OF the three winter months was a little over
~ deg; showing mean difference on that part M
the coast, OF only III deg. between summer and win
ter. .#@
The mean temperature of San Francisco for ths
three winter months, was precisely the ssnc an AZ
Aonterey--a little over 40 deg. am.
As these cities are only about one degree and
half distant from each other. and both situated near
the ocean, the temperature at both, in summer, nav
very reas onahy be supposed to be nearly simi-
lar as the thermometer shows it to be in winter.
The mean temperature Of July, August and sep.
temher, at San Diegofoniy deg. 6s min. south OF
Monterey, vas - deg. The mean temperature of
the same months at Monterey was little over SO
deg; showing mean difference of Is deg.
This would seem to indicate that the cold ocean
current is thrown oil from the southern part or tho
coast by Point Conception, and the islands south or
l.; ana srguerty its influence the climate Of
San Diego is much less than ut Monterey and San
Francisco.
At Los Angeles. 10 miles distant from the coast.
the mean temperature Of the three months was ~
deg; Of the three autumn months 81 deg; Of the
three winter months 81 deg.
AtSuters, i!lc, about hundred and thirty miles
f;om the ocean. and four degrees north or Lo. An

Of the same months at Monterey was 90 degrees
showing difference of leg between the sea. COAST
and the interior, nearly the parallel Of lat
itude. much greater difference would undcubt-
ediy appear if VIC had observation for the spring
and summer months at Suttersviile and the gold
mines. zs@
