Marshall ifennctt were engaged with a party in erecting a saw mill for Capt. J. A. Sutter, "on the American Fork of the Snc ramento river, about forty miles above its mouth. In excavating the tail race, they re moved the rock during the day and let in 'he water after nigh, in order to wash out the loose dirt and sand. On the morning of the 10h, af ter shutting off the water, Mr. Marshall jdiB jovercd (he .first qld. lyino-nn deenmnosed eraiv ite in in e bottom of the race. It would seem (hat but little doubt was entertained of its be ing the real 'simon pure, for operations imme diately ceased on the mill, and all hands com menced searching for gold. It was soon found that gold abounded along the American Fork lor a distance of thirty miles. For a time the discoverers were the only ones aware of the fact, but the news finally spread through the set tlements. But little credit however, was gained by the report, though occasionally a solitary "gold hunt er" might be seen, stealing down to a launch with a pick and shovel, moro than half ashamed of his cre dulity. Some lime during the month of May, a num ber of credible persons arrived in town from the scene of operations, bringing specimens of the ore, and stating that those engaged in collecting the precious metal were making from 3 to sio per day. Then commenced the grand rush ! The inhabitants through out the territory were in commotion. Large compa nies of men, women and children could be seen on every road leading to the mines, their wagons load ed down with tools ior digging, provisions, Launch aftor launch left the wharves of our city, crowded with passengers and freight for the Sacramento. Me chanical operations of every kind ceased, whole streets, that were but a short week before alive with a busy population, were entiroly deserted, and the place wore the appearance or a city that had been suddenly vis ited by a devastating plague. To cap the climax, newspapers uere obliged to stop printing for want of readers. Meantime our mercantile friends were doing an un wonted "stroke" of business, Every arrival from the mining district brought more or less gold dust, the major part, of which immediately passed into the hands of merchants for goods, etcImmense quanti ties of merchandise were conveyed to the mines, un til it became a matter of astonishment where so much could be disposed of. During the first eight weeks of the "golden limes'' the receipts at this place in pold dust amounted to 525,000. For the eight weeks ending at this date, they were C6OO.000. The number of persons now engaged in gold hunting probably exceed 60CO, including Indians, and one ounce per day is the lowest average we can put for each person, while many collect their hundreds of dollars for a number of days in succession, and instances have been known where one individual has collected from i5oo to si boo worth of pure gold in a day. Explora tions have been progressing, and it is now fully as certained that gold exists on both sides of the Sier ra Nevada, from lat. 41 North to as far South as the he?d waters of the San Joaquin river, a distance of i-Cr-ilcc in length and 100 in bcojutth. Tarlhor than - this has not been explored, but from the nature of the country beyond the sources of the San Joaquin, we doubt not gold will also be found there in equal abundance. The gold region already known is how ever sufficiently Extensive to give profitable employ ment to 100,000 persons for generations to come. The ore is in a virgin state, disseminated in small doses, and is found in three distinct deposits sand and grav el beds, on decomposed granite, and intermixed witk a kind of slate. For a long time subsequent to the discovery of the mines, the only implements ueed in washing the gold were large tin pans, or Indian baskets. Latterly; "machines" were usedat first a rough log hollowed out (in some instances) by burning, and scraping with a butcher knife; afterwards more finished ones made their appearance, built of red wood boards ia the shape of an ordinary trough, "about ten feet long and two feet wide at the top, with a riddle or seive at one end to catch the larger graved, and three or four smal bars across the bottom, about half am. inch high to keep the gold from going out with the dirt and water at the lower end. This machine is sol upon rockers, which gives a half rotary motion to the water and dirt inside." Four men are requi site to work one of these machines properly. (Californian. qjt The Washington Union publishes an official army order, wherein the President directs it to be anounced in 'general orders that deserters from the army at large, may peacably return to their homes without being subject to punishment or trial on ac count of such desertion. i
