and these phenomena are of daily occurrence, with few exceptions, throughout the dry season.
"The cold winds and fogs render the climate at San Francisco, and all along the coast of California, except the extreme southern portion of it, probably more 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 wind from the ocean, the climate is moderate and delightful. The heat in the middle of the day is not so great as to retard labor, or to render exercise in the open air uncomfortable. The nights are cool and pleasant. This description of climate prevails in all the valleys along the coast-range, and extends throughout the country, north and south, as far eastward as 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. It is dry, however, and probably not more oppressive. On the foot-hills of the Sierra Nevada, and especially in the deep ravines of the streams, the thermometer frequently ranges from 110° to 115° in the shade, during three or four hours of the day, from eleven until three o'clock. In the evening, as the sun declines, the radiation of heat ceases. The cool, dry atmosphere from the mountains spreads over the whole country, and renders the nights fresh and invigorating. *********
"These variations in the climate of California account for the different conflicting opinions and statements respecting it. A stranger arriving at San Francisco in summer, is annoyed by the cold winds and fogs, and pronounces the climate intolerable. A few months will modify if not banish his dislike, and he will not fail to appreciate the beneficial effects of a cool, bracing atmosphere. Those who approach California overland, through the passes of the mountains, find the heat of summer, in the middle of the day, greater than they have been accustomed to, and therefore many complain of it.
"Those who take up their residence in the valleys which are situated between the great plain of the Sacramento and San Joaquin and the coast range of hills, find the climate, especially in the dry season, as healthful and pleasant as it is possible for any climate to be which possesses sufficient heat to mature the cereal grains and edible roots of the temperate zone."[1]
