1OI IAi1il$ HI q oilOAC DI''tOC VI NAAAAS , perfect torrents of water, rolling as an immense breaker, sweeping and carrying everything before it, throwing the rocks, boulders and gravel, with all coarse material, up on the banks, where they are placed, leaving nothing but the fine sand and other matter that from it's lightness is held in the water to gradually settle on the bottom and center of the gulches, ravines and courses, will arrive at the conclusion, that so with the geld, it is carried with the larger and heavier material from the great rush and sudden pas sage of a large body Of water, and deposited on the top and sides of the channels. Hence"We account for the Mexican placer mines al- ways working and drifting into the banks of the arroyas. All zona seldom has any steady and gradual rains and fall of water, as the winter rains of California, where the water slowly meanders along the plains, gradually finding it's way to the water courses, roll ing the coarse and fine gold along till it gradually sinks in the sand and gravel and finds its place on the bedrock or bed of the stream. Again are found rich surface dig gings, nuggets of silver almost pure, masses of chIoride5 and sul- phurets of silver, and in the galena districts great bouIders of the ore on the fat lands and sides of mountain ranges, all displaced from the veins and ledge matter during the time of heavy rain falls. The rains Of Arizona occur during the summer months, when the whole crust of the earth is heated, the rocks showing by their dark and burnt appearance the effects of the high tempera- ture. During the time of this heat the rain pours from the heavens, suddenly cooling; causes the rocks, vein-croppings and for nations carrying minerals to crack and burst assunder, rolling down the mountain sides, the metal becoming detached and thus found as float, the action of the elements, atmosphere and time, destroying the sulphur, antimony and ba6er metals, leav- ing the silver in its pure and nat ural state.
 Taking passage on the train of 
 the s. ?. B. R., at i P. M., from San Francisco, passing the rich agricultural districts of San Joa- quin and Sacramento, thence over the mountain ranges down into the valleys of Los Angeles and San Bernardino, we see the last of agricultural lands and note the mountain ranges to the left, in which are located the great mines of Southern California; then 9 ride of about fifteen hours by night. Early next morning we have the | Colorado river in view, with it's river ranges, the Carga-DLuchacho and Chimney Peak, the Picacho on the California side of the river. In these mountains several mines are opened and being worked for gold. After crossing the river
 the train landed in the town of Yuma, ArIzona. Here can be seen the steamers of the Colorado Steam Navigation Company ar- irving from the upper Colorado ! river, laden with ores and bullion from the mines above; and again,
 teams from the interior of the
 Territory, with their loads of ore and the precious metals for ship
 ment to San Francisco, where are 1 centered the buyers for the east ern smeltars and European work
 CTS of ores.
