The cold, dry cnFrsnts of air from the northeast
 after passing the Rocky mountains and the Siefrs i Nevada. descended to the Pacific, and ahsOFd ths moisture of the atmosphere, to a great disiaace
 from the land. The cold air from ihs moautsins

 nubrOksn rays the dry, unprotected susface of country. the heat becomes much greater inland
 than II is on the ocean, that an under-curFent of cold ait, bringing the fog with it, rushes over the coast ranEe Of hills, and through their numerous Passes, toward the interior.
 Every day. as the heat. inland, attains suffi- cient temperature, the cold dry wind from the ocean commences 10 blow. This is usualiy from II 10 o'clock and as the day advances the wi0d increases and continues to blow till late at night. When the vacuum is filled, or ths equibrium of the atmosphere restored. the wind ceases a perfect calm prevails until about the same hour the foI- lowing day, when the sams process commences and progresses as before, and these phenOsnena are of daily occurrence, with few exceptions, throughout the dry season.
 These cold winds and fogs render the climate at San Francisco and all aong ths coasts of Califor. nia except tho extreme sOuIherR portion of it, pro- bably uncomfortable, to those not accustomed to it, in summer than in winter.
 A few miles inland, where the heat of the sun modifies and softens the wiud from the ocean, the climate is moderate and delightful The heat in the middle Of the day is not great 10 rctard

The nights are cool and pleasant This des- cripton of climate prevails in ali the valleys a!onK fh .t- el try, north and south. far eastward as the valley of the Sacramento and San Joaquin. In this vast plain the sea- breeze fooses ifs influence and the de- gree of heat in lhe middle of the day, during the summer months, is much greater than is know on the Atlantic coast in inc same attitudes II Is dry, however. and probably not more oppressive. On the foot hills of the Sierra Nevada, aud especially in the deep raynes of he streams the therinomet frequently ranges from li00 10 ll5o in the shade during three or hour hours of the day, say from until o'clock. la the evening. the sun declines the radistion ofheat ceases. The cool, dry atmos- phere from the mountains, spreads over tho whole country. and renders the nights cool and iavigora ungs
 A long lis, Is given of different thermometreaI observations in various parts 1.-the territory show ing the mean temperature upon the coast to be in the neighborhood of 10o in the summer months. and 50' in the winter, and that ihe temperature inland is about So greater than upon the coast:
