194 GEOLOGY AND MINERALS. 



The wild clover of these valleys is much like the common red, and, in 

 some places, is afforded in great abundance. It attains a usual height of 

 two feet and a half, though it often measures twice that height — standing 

 as thick as it can well grow. 



Forty bushels per acre is said to be the average wheat crop, but sixty 

 and even one hundred bushels have been grown upon a hke spot of ground. 

 This grain generally reaches its maturity in three or four months from 

 the time of sowing. 



Corn yields well, and affords an average of from fifty to sixty bushels 

 per acre, without farther attention from the time of planting till picking. 

 Potatoes, onions, beets, carrots, &:.c., may be produced in any quantity with 

 very little trouble. Tobacco has also been raised by some of the inhabit- 

 ants with most flattering success. 



Perhaps, no country in the world is possessed of a richer or more fruit- 

 ful soil, or one capable of yielding a greater variety of productions, than 

 the valleys of the Sacramento and its tributaries. 



The articles previously noticed are more or less common to the bottoms 

 and valleys of other sections. Grapes abound in the vicinity of most of 

 the creeks, which afford generous wines and delicious raisins in immense 

 quantities. 



The climate is so mild that fires are needed at no season of the year for 

 other than cooking purposes. By aid of irrigation, many kinds of vegeta- 

 bles are fresh-grown at any time, while two crops of some species of 

 grain may be produced annually. 



Flowers are not unfrequently in full bloom in mid winter, and all nature 

 bears a like smiling aspect. In this, however, we of course refer only to 

 the low-lands and valleys. 



The traveller at any season of the year may visit at his option the frosts 

 and snows of eternal winter, or feast his eyes upon the verdure and beauty 

 of perennial spring, or glut his taste amid the luxuriant abundance and rich 

 maturity of unending summer, or indulge his changeful fancy in the en- 

 joyment of a magnificent variety of scenery as well as of climate, soil, 

 and productions. 



The only rains incident to this country fall during the months of De- 

 cember, January, February, and March, which constitute the winter ; at 

 other times rain is very rarely known to fall. Perhaps, for one third of the 

 four months before named, the clouds pour down their torrents without in- 

 termission ; the remaining two thirds afford clear and delightful weather. 



During the wet season the ground in many parts becomes so thoroughly 

 saturated with moisture, particularly in the valley of the Sacramento, 

 that, by the aid of copious dews to which the country is subject, crops may 

 be raised without the trouble of irrigation ; though its general aridity con- 

 stitutes the greatest objection to California. 



Of its geological and mineralogical character little is yet known. The 

 prevailing rock is said to be sandstone, mica slate, granite, trap, basalt, 

 puddingstone, and limestone, with occasional beds of gypsum. Among 

 its minerals as commonly reported, are found gold, silver, iron, coal, and a 

 variety of salts. The mineral resources of the country have not been as 

 yet fully investigated to any great extent, but the mountains, in different 

 parts, are supposed to be rich in hidden stores.
