From CALIFORNIA we have intelligence to Dec. 15th. New and extensive deposits of gold have been found near Auburn, in the northern, and at Mariposa, in the southern mines; the lack of rain had caused the yield of gold from them to be small. The aggregate product of all the mines during November was estimated at twenty per cent. less than during the previous month. Several projects of railroads through different sections of the State were under discussion, and the route between San Francisco and San José was being surveyed. The agricultural resources of the State continued to be developed with steady progress. Farming operations had already commenced. Several murders had been perpetrated in various sections. As an evidence of the prosperity of San Francisco, it is stated that seven large steamers were to leave that port, within a week, for different ports on the Pacific and Australia. The Indians have again been committing frightful ravages among the American settlements on the Colorado. The various tribes upon the southeastern border, known to be disaffected, have given unmistakable signs of revolt. Juan Antonio, who had been prominent as an Indian leader, had been forming a league of several tribes, with intent to attack the towns of San Diego, Los Angeles, and Santa Barbara. Three skirmishes had also taken place with the Yumas, on the Colorado, in which several Americans were killed. Great uneasiness prevailed among the inhabitants of the menaced districts. The latest advices represent the danger as less menacing than was feared. Gen. Conde, with 80 troops of the Mexican Boundary Commission, was at Tuson on the 20th Oct., and would leave next day for the Gila. From OREGON, our news is to Dec. 6, and is encouraging. The difficulties with the Coquille Indians, which had caused the loss of many lives, had been settled. Coal had been found in considerable quantities at Port Orford. The U. S. Coast Survey party were engaged in determining the latitude and longitude of that point, and had completed a map of the harbor. The rainy season had commenced, and the rivers were rising. From UTAH we have the official report made by the Judges to the President of the United States, concerning the condition of the Territory. They state that they were compelled to leave by the hostile and seditious sentiments of the Governor, Brigham Young; and they give a detailed statement of his proceedings. They represent polygamy as common there, and the courts as powerless to punish any offenses. The delegate from that Territory in Congress complains of the report, as calculated to do injustice to the inhabitants. He demands an investigation into the charges.
