The old adage, "a rolingstone gathers no moss," is exemplified every day here. The same restless spirit that prompted men to come, keeps them constantly on the move while here. Many who are making from three to six dollars a day, work until they obtain two or three hundred dollars, then hearing of richer diggings otherwheres, pull up and leave sure work and travel until they have spent what they have got and a month or two in prospecting, when they become strapped, to use a favorite expression here, and are compelled to work for less pay, until they make a raise, when the same spirit puts them in motion again. I have known men who have been here two years, and have sometimes had a thousand dollars on hand, that, when I saw them, had not a dollar, and were compelled to obtain credit to enable them to live for a time until they could make a raise again, and all the result of this restless spirit. In my opinion one half of the aggregate time of the miners of California is spent in traveling from one section of the mines to another. California may be properly divided into four ranges, or divisions. The first, the alluvial bottoms of the rivers or bays, and the plains, which comprise all of the agricultural country in the State, the area of which would probably amount to one half of the area of the State of Illinois. This range is exceedingly fertile, probably equal to any soil on the earth. The climate is excellent, the air pure and healthy, neither too cool nor too hot, and well calculated for the products of a temperate climate, as well as many of tropical. Grass grows on the bottoms all the year, and farming may be carried on in all months of the winter, if not prevented by the rain. No frosts ever nip the crops, and the seasons present a perpetual spring. The plains are somewhat elevated from the bottoms, gently rolling, and resemble our prairies. The soil is fertile, but cannot be cultivated without irrigation in the summer, although crops are raised by sowing in November and December, which enables them to get so far advanced by the commencement of the dry season as to avoid the drouth. In the spring they are covered with a great variety of flowers, wild oats, and clover. The timber on this range consists of live oak, and various oaks resembling white burr and black oak, besides various shrubs. The second range is the lower hill or mountain range, which is also the gold range. The soil would admit of cultivation if it could be irrigated, but this would be impossible, from the nature of the country. It will be only available for its gold, which is inexhaustible in my opinion, although the business of gathering it will not be as profitable hereafter as it has been. The timber in the range consists of the various kinds of oak and pine, with some cedar and spruce; it is not valuable, but will answer the wants of this range for the present. The third range is the timber range, which in time will be the most valuable part of California. Probably no part of the world will furnish such pine and cedar timber. The valleys are filled with trees from two to three hundred feet high, clear from limbs nearly to their tops, and of the best quality for lumber; many of the trees from five to ten feet in diameter at the foot. I saw a pine tree said to be 11, and a cedar 15 feet thro', and have no doubt but such was the fact. They can only be got out of the mountains by railways or the rivers at flood time, consequently it will be some years before the attention of the Californian will be turned to this branch of trade. But little gold has been found in this range, or probably ever will be, as the quartz veins, the original deposit of gold, if they exist at all in it, lie deep under the granite ridges.
