Assistance pon Ohegos. We learn from C. E. Pick ett, Esq., U. S. Indian Agent, that Gor. Mason has res ponded to the call of Gov. Abernelhy for assistance in arras and ammunition, and that they will be dispatched by the first opportunity. Mr. Pickett, we understand, on learning of the Indian difficulties in Oregon and previous to any call having been made on Gov. Mason, proceeded at once to Monterey tosolicit aid of the U.S. authorities, with the intention of accompanying such to Oregon, and assuming the office of Sub-Indian Agint there until lis successor should arrive. Gov. Mason, however, declined sending aid in the shape of officers and money, and also advised Mr. Pickett against assum ing his proposed responsibility of mustering the forces in that territory into the service and pay of the United States, and making the United Slates government lia ble for all the expenses of the war; staling it as his opinion that Gov. Abernelhy is the only pioper and le gitimate person to conduct this affair at presi nt, and that his acts will be sanctioned by the general govern ment, if done conformably to the U.S. laws. Mr. Pickett, we believe, is still inclined lo avail him self of the first conveyance lo proceed to Oregon, pro vided an early opportunity is offered.Californian. The brig Henry, Capt. Kilborn, has arrived with '25 barrels of gun-powder, 127 boxes, containing 1000 rounds each, 'fixed ammunition,' 27 cases of guns rifles, yagers, etc., etc. Some 8 or 10 boxes of knap sacks, cartridge-boxes, canteens, belts, etc., etc., 1 piece from a battery or Col.

The Gold Region. -It was our intention to present our readers with a" description of the extensive golfr, silver and iron mines, recently discovered in the Sierra Nevada, together with some other important items, for the good of the people, but we are compelled to defer it for a future number. But to enable our distant rea ders lo draw some idea of the extent of the gold mine, we will confine our remarks to a few facts. I he coun try from (be Ajuba to Ihe San Joaquin rivers, a distance of about 120 miles, and from the base towards the sum mit of the mountains, as far as Snow Hill, aboul 70 miles, has been explored, and gold found on every part. There are now probably 3000 pmple, including Indians, engaged collecting gold. The amount coll cl cd by each man who works, rang s from 10 lo .ISO dollars per day. The publish r ol liiis paper, while on a tour alone to the mining district, coll cled, o.ith the aid of a shovel, pick and tin pan, about twenty in ches in diameter, from U lo 128 dollars a day aver aging 100 dollars. The gross amount collected will pro bably exceed GOO.000 dollars, of which amount our merchants have received about 230,000 dollars worth for goads sold all within the short space of eight weeks. The largest piece of gold known to he found weighed four pounds. Californian. News Items. The "Cainoruian" sajs: Capt. Van Vlietand Lieut. Woodbun, of Ihe Engineers, are en gaged in building m litary 'posts on the roule ti. Califor nia and Oregon: one at Grand Island, on the Platte river, and another near Ft. Laramie.

The Secretary of the Navy states that the contract for carrying the mail from Panama to Oregon is taken for ten years, for 199,000 dollars per annum, by a Mr. Harris. It is to be carried monthly in steam vessels, and it to go into operation this year. LxnonERs. Labor has ever been high in California, but previous to the discovery of the 'placero' gold, the rales ranged from one to three dollars per day. Since that epoch common labor cannot be obtained, and if to be had, for no less price than 50 cents pur hour, and that the most common. Carpenters and other mechan ics have been ollered 15 dollars per day, but it has been fl.illy refused. Many of our enterprising citizens were largely engaged in building, and others wish lo com mence on dwellings, warehouses and the like, but all have had to suspend for the lack of that all important class of community the working men.
