53.5 deg., 54.7 deg., 56.0 deg., 58.2 deg., 60.2 deg., 64.6 deg., 67.1 deg., 69.0 deg., 66.7 deg.,
62.9 deg., 58.1 deg., 56.0 deg.. In the year 1877 the mean temperature at 3 P.M. at
San Diego was as follows, beginning with January: 60.9 deg., 57.7 deg., 62.4 deg.,
63.3 deg., 66.3 deg., 68.5 deg., 69.6 deg., 69.6 deg., 69.5 deg., 69.6 deg., 64.4 deg., 60.5 deg.. For the
four months of July, August, September, and October there was hardly a
shade of difference at 3 P.M. The striking fact in all the records I
have seen is that the difference of temperature in the daytime between
summer and winter is very small, the great difference being from
midnight to just before sunrise, and this latter difference is greater
inland than on the coast. There are, of course, frost and ice in the
mountains, but the frost that comes occasionally in the low inland
valleys is of very brief duration in the morning hour, and rarely
continues long enough to have a serious effect upon vegetation.

In considering the matter of temperature, the rule for vegetation and
for invalids will not be the same. A spot in which delicate flowers in
Southern California bloom the year round may be too cool for many
invalids. It must not be forgotten that the general temperature here is
lower than that to which most Eastern people are accustomed. They are
used to living all winter in overheated houses, and to protracted heated
terms rendered worse by humidity in the summer. The dry, low temperature
of the California winter, notwithstanding its perpetual sunshine, may
seem, therefore, wanting to them in direct warmth. It may take a year or
two to acclimate them to this more equable and more refreshing
temperature.

Neither on the coast nor in the foot-hills will the invalid find the
climate of the Riviera or of Tangier--not the tramontane wind of the
former, nor the absolutely genial but somewhat enervating climate of
the latter. But it must be borne in mind that in this, our
Mediterranean, the seeker for health or pleasure can find almost any
climate (except the very cold or the very hot), down to the minutest
subdivision. He may try the dry marine climate of the coast, or the
temperature of the fruit lands and gardens from San Bernardino to Los
Angeles, or he may climb to any altitude that suits him in the Sierra
Madre or the San Jacinto ranges. The difference may be all-important to
him between a valley and a mesa which is not a hundred feet higher; nay,
