STATE OF CALIFORNIA DURING THE YEAR 1886, 



BY THE 



Meteorological Department of the State Agricultural Society. 



Collated and compiled by Sergeant James A. Barwick, Observer Signal Corps, TJ. S. A., 

 and Meteorologist to the State Board of Agriculture. 



To the Secretary of the State Agricultural Society of California: 



Sir : I have the honor to submit the following animal meteorological 

 review of California for the year ending February 28, 1887. There will be 

 found an extensive and general review of the weather for Sacramento in 

 all its phases for many years. A table of dates of the first light and first 

 killing frost of the season, and the lowest temperature at the time of last 

 frost, also the dates of the last killing and last light frost of the season, 

 along with the lowest temperature at the occurrence of the last frost, and 

 the dates of the first blooming of fruit trees, from 1869-70 to 1886-7, by 

 Mr. S. H. Gerrish, of Sacramento. A report on the topography and climatol- 

 ogy of Surprise and Goose Lake Valleys, by Dr. George M. Kober, U. S. A., 

 Fort Bidwell, Modoc County. This report was taken from the biennial 

 report of the State Board of Health for 1886. I would call especial atten- 

 tion to it, because it is the first time a report on the climate of that portion 

 of California has been published. The data covers a period of about twenty 

 years. A report on the coast climate of this State, from the State Board 

 of Health report for 1886, by Dr. John W. Robertson, of Crescent City, Del 

 Norte County. It also contains a report on the therapeutics of the coast 

 climate, An article on the climatology of Southern California, by Dr. H. 

 S. Orme, President of the State Board of Health, and is from his article in 

 the ninth biennial report of the State Board of Health for 1886. An orig- 

 inal article by Lieutenant W. A. Glassford, Signal Service TJ. S. A., entitled 

 " Weather Types on the Pacific Coast." This is an intensely interesting 

 and instructive article, inasmuch as it gives the causes of the desiccating 

 northerly winds that occasionally blow over our valleys. It will well repay 

 careful study by all persons interested in the peculiarities of the Pacific 

 Coast weather. Carefully prepared statistics on the climate of Santa Bar- 

 bara, by Mr. Hugh D. Vail, from observations taken at his observatory at 

 Santa Barbara. A general review of the climatic conditions of Oroville 

 and vicinity, by Mr. Hiram Arents, Meteorologist and Voluntary Observer 

 of the Signal Service, TJ. S. A. 



There will be found an interesting table of mean temperature, total 

 rainfall, and the elevations of over one hundred different points in Cali- 

 fornia, taken mostly from the Southern Pacific Railroad Company's reports, 

 and covers periods of from two to sixteen years. Too much credit can
