In marked contrast with the destructive un rest which gave rise to tli9 ruined towns of Neva, is the orderly deliberation into which miners settle in developing a truly valuable mine. At Eureka we were kindly led through the treasure-chambers of the Richmond and Eureka Consolidated, our guides leisurely lead ivg the way from level to level, calling atten tionajto the precious ore masses which the workmen were slowly breaking to pieces with their picks like navvies wearing away tbe day in a railroad cutting ; while down at the smelt ing works the bar* of bullion were handled with less eager haste than the farmer shows in gathering his sheaves. The wealth Nevada has already given to the world is indeed wonderful, but the only grand marvel is the energy expended ia its development. The amount of prosp&cting done in the face of so many dangers and sacrifices, the innumerable tunnel? and shafts bored into tbe mountains, the mills that have bean built — fhese would seem to require a race of giants But, in full view of the substantial results achieved, the pure waste manifest in the ruins one meets never fails to produce a saddening effect. The dim old ruins of Earope, so eagerly sought after by travellers, have something pleasing about them, whatever their historical associations ; for they at lea3t lend some beauty to the landscape. Their picturesque towers and arches seem to Le kindly adopted by nature, and planted with wild flowers aud wreathed with ivy ; while their rugged anglf s »rd soothed and fraehened and embossed with green aiotse-t, freah life and decay migling in pleasing measures, and the whole vanishing softly like a ripe, tranquil day fading iuto night. So, also, among the older ruins of the East there is fitness felt. They bave served their time, and, like the weather-beaten moun tains, are wasting harmoniously. Tho same is; in some degree true of the dead mining towns of California. But those of Nevada waste in tbe dry wilderne s like the bones of cattle that have died of t^itst. Many of them do not represent any good accomplishment, and have no ri^hfc to be. They are m -numente of fiaud and ignorance — sins against scieace.
