TRANSACTIONS OF THE 



OROVILLE ORANGES. 



The Oroville oranges have been pronounced equal to the best from Los 

 Angeles. 



The vine grows with luxuriance, and bears abundantly wherever it has 

 been planted throughout all this region. 



" The wines of Coloma have more than a local reputation. Persons com- 

 petent to judge assert that wine from grapes grown on the foothills is free 

 from the earthy taste that characterizes much of the wine of the flat land 

 of the valleys. They also express the belief that if ever wine is to be made 

 in California as light as that from the Rhine, and as free from alcohol, the 

 grapes will be grown in the higher elevation of the foothills, where snow 

 falls and remains on the ground a few weeks each season. It is said that 

 the long Summers and great heat of the valleys develop the saccharine 

 matter in the grape, which by fermentation is converted into alcohol." 



I will annex to this excellent article of Mr. Redding's on the climate 



and capabilities of the Sacramento Valley and foothills, a table of mean 



temperatures, maximum and minimum temperatures, clear, fair, and 



cloudy days, average cloudiness, and rainfall for the four seasons of the 



year, taken from the annual report of the Chief Signal Officer for the year 



1884. These seasonal means, etc., are calculated from observations of from 



seven to ten years, and give a better average than if they were only for 



one year. The headings of the tables will explain themselves and are as 



follows:
