Average Precipitation in Humboldt County. 



TRINITY COUNTY. 



This county properly belongs to the class whose trade is directly tribu- 

 tary to the Sacramento Valley. It adjoins Humboldt on the west, but 

 draws its supplies chiefly through the railroad system that penetrates 

 Shasta on the east. Its area in square miles is 2,625, and its acreage is 

 1,680,000. 



Rainfall at Weaverville, Trinity County. 



The opening of the northern portion of the State to settlement, as evi-

 inquiries concerning lands in that region for various uses, renders the 

 amount of annual rainfall of that division of the State a subject of interest 

 and value to the prospector. We therefore give below, by months and 

 seasons, the amount of rainfall and melted snow which has been precipi- 

 tated at Weaverville, Trinity County, from July 1, 1871, to December 23.
