Sir: I have the honor to submit the following meteorological report on 

 the climate of California, and more especially that of the great interior 

 valleys of this State. Then- will be found the rainfall by seasons, Spring, 

 Summer, Autumn, and Winter, for Sacramento, compiled from observations 

 taken by Dr. T. M. Logan, Dr. F. W. Hatch, and those of the United States 

 Signal Sen-ice, covering a period from 1853 to April 1, 1886. Also a gen- 

 eral review of the meteorological condition of Sacramento, as deduced from 

 Signal Service observations from July 1, 1877, to February 28, 1886; show- 

 ing the pressure of the atmosphere by seasons, the temperature, direction of 

 wind, velocity of wind, clear, fair, cloudy, and rainy days, and various other 

 data pertaining to the climatic conditions of the above named city. A 

 tabulated statement of rainfall by months, years, and seasons, from near

 Princeton, West Butte, Grass Valley, Placerville, Georgetown, Nicolaus, 

 Folsom City, Sacramento, Oakland, San Francisco, Salinas, Santa Barbara, 

 Los Angeles, San Bernardino, San Diego, and Poway; the above places

 age estimate of the precipitation from San Diego to Siskiyou, and from 

 the Sierras to the sea. A supplemental report of the rainfall for January, 

 1886, and for the season of 1885-6, up to February 1, for the above named

 vice Station, and for the stations of the Southern Pacific Railroad Com- 

 pany, voluntary observers, and Post Surgeons. This data was collated and
