12 RESOURCES OF CALIFORNIA. 



16. Counties. California has fifty-three counties. Those 

 in the northern half of the State, are Del Norte, Klamath, 

 Humboldt, Mendocino, Modoc, Sonoma, and Marin, on the 

 coast ; Lassen, Sierra, Nevada, Placer, Ell Dorado, and Ama- 

 dor, on the eastern border; and Shasta, Siskiyou, Trinity, 

 Tehama, Plumas, Butte, Colusa, Yuba, Sutter, Lake, Yolo, 

 Napa, Solano, and Sacramento, inner counties. 



In the southern half of the State, are San Francisco, San 

 Mateo, Santa Cruz, Monterey, San Luis Obispo, Santa Barbara, 

 Los Angeles, and San Diego, on the ocean ; Mono, Inyo, and 

 San Bernardino, on the eastern boundary ; Calaveras, Tuol- 

 umne, Mariposa, Fresno, Tulare, Kern, San Joaquin, Stanis- 

 laus, Merced, Contra Costa, Alameda, San Benito, and Santa 

 Clara, which do not reach to the border. San Diego reaches 

 entirely across the State, and is the only county that does. 



17. Maps. Among the maps prepared by C. F. HolF- 

 manu, of the State Geological Survey, and executed in the finest 

 style of topographical work, and with great accuracy, are the 

 following : 



1. A map of Central California, on a scale of six miles to 

 an inch. It covers an area three hundred miles square, its 

 northern line being beyond Lassen's Peak and Cape Mendocino, 

 its eastern beyond Owen Lake, its southern beyond Yisalia and 

 Point Sur, its western beyond Point Reyes. All that part of 

 this region in California has been carefully surveyed by the 

 State Geological Survey, except a little strip in the Coast 

 mountains north of Clear Lake. The scale of the map is six 

 miles to an inch, and the style of execution is superior to that 

 of any other map ever made in the New World, of a State, or 

 any large area. This map is published. 



2. The triangle south of Central California, on the same 

 scale, with equal thoroughness. Its northern and eastern sides 

 are about two hundred miles long, and its southern and west- 

 ern boundaries are the ocean. This map is to be published 

 soon.
