thermometer ranging above 100° there is no such thing as a sunstroke. 

 During the warm period, the atmosphere and soil are both dry, hence a 

 heat of 100° is not so oppressive in Solano County as is a heat of 75° in the 

 Eastern States. A climate that will admit of an open-air life the whole 

 year round, is a peculiar advantage, that Solano can lay claim to in an 

 eminent degree. 



HEALTHFULNESS. 



There is no section of the State that surpasses Solano County, from a 

 sanitary point of view. The reports of the State Board of Health, as well 

 as the opinions of the most eminent physicians, justify this assertion. 

 From a bulletin issued in 1881, it is learned that Vallejo is the healthiest 

 city in the United States, and the balance of the county is equally as 

 healthy. There is no malaria, no miasma, and but few cases of asthma 

 and catarrh. People suffering with pulmonary diseases have been greatly 

 relieved by the climate of this county. In fact the climate and tempera- 

 ture are conducive to the enjoyment of perfect health, and these are con- 

 siderations that cannot be overestimated by the thousands of immigrants 

 now seeking homes on the Pacific Slope. 



EAINFALL. . 



An idea can be formed of the amount of the rainfall in the agricultural 

 and horticultural districts, by making comparison between Dixon, Vaca- 

 ville, and Suisun. 



At Dixon, during the winter of 1878-9, the rainfall was 17.85 inches; 

 the next winter it was 15.35 inches; the following winter, 21.54 inches; and 

 the next winter, 10.24 inches; and in 1882-3, 13.24 inches; making an 

 average, for five years, of 15.64 inches per year. At Vacaville, the aver- 

 age for the same period is 30.3 inches per year. At Suisun, the average is 

 20.5 inches per year. 



Water is easy of access all over the county. In the southern and middle 

 portions there are numerous mineral springs, two of which, the White Sul- 

 phur Springs, in the vicinity of Vallejo, and the Tolenas Springs, near 

 Suisun, have already attracted much attention, and promise to become 

 famous as places of public resort. In northern Solano there are no streams 

 that run the year round, except Rio de los Putos, the boundary. An abun- 

 dance of good water can, however, be obtained by boring, and the average 

 depth is about twenty feet, though the purest and softest water is obtained 

 at a depth of seventy to ninety feet, according to locality. 



The State of California has the most remarkable climate of any subdi- 

 vision of the known world; and it may truthfully be added that no prov- 

 ince has such a diversity of climate. The solar heat, the ocean currents, 

 the trade winds, and the configuration of the mountains, operating with each 

 other under a great variety of circumstances, are the responsible cause for 

 the checkered climatic condition of the Pacific Coast. Suisun Valley stands 

 directly in the path of the inland trade winds which, for eight or nine 

 months, blow gently inland and northward, supplying the vacuum created 

 by the uprising of the heated air of the great Sacramento plains. At this 

 distance from the sea these winds are strong enough to beat back the hot 

 breezes of the Sacramento Valley, and the result is that the climate is one 

 of great evenness, with no extremes of chilly coldness or enervating heat. 

 To this favorable climatic condition may be added another desirable fact, 

 that Suisun and its surroundings is scarcely ever visited with sea fogs 

 which operate so much to endanger health, spoil ripening fruits, and mil-
