From California we have news of continued prosperity in mining, and in agriculture and general interests. The project for dividing the State into North and South California appears to have been urged with determination and hopes of success in the recent convention held to consider the subject. It is stated also that a large company of emigrants recently left San Francisco for the Sandwich Islands, to establish a Republican State there. To this end a Constitution had been formed in San Francisco prior to their departure. There are many circumstances which render this statement probable. A Governor, Lieut. Governor, Attorney General, and members of the Legislature were elected in Virginia on the 8th of December, under the new constitution. The democrats elected their ticket by a large majority. The Legislature of Indiana convened at Indianapolis on the 1st December. Lieutenant Governor James H. Lane took the chair of the Senate, and John D. Dunn was chosen Secretary. In the House, John W. Davis (formerly Speaker at Washington, and since Commissioner to China) was chosen Speaker by a unanimous vote. The Senate of South Carolina has refused an application from the Federal Government for the sale of the lighthouse at Bell's Bay. The House of Representatives has again refused to allow the people to choose Electors of President and Vice President. The vote was 66 to 48. The Legislature have passed a bill to provide for the holding of a Secession Convention. The Texas Legislature assembled at Austin on the 3d. Advices from Galveston state that Colonel Rogers has succeeded in effecting a treaty with the Camanche Indians, and recovered twenty-seven white captives from the Camanches, who had been in bondage among them. Of accidents and disasters, there have not been so many as in some previous months. On the morning of November 27, about two o'clock, a frightful collision took place between the steamers Die Vernon and Archer, resulting in the loss of the latter vessel, with serious loss of life. The accident occurred at Enterprise Island, about five miles above the mouth of Illinois River. The whole number of lives lost by this catastrophe was thirty-four, of whom ten were deck hands or firemen engaged on the boat. On Sunday, December 7, the city of Portland was visited by one of the most destructive conflagrations that ever occurred in that place. The extent of the conflagration was owing mainly to the want of water, the tide being down. There were twenty-seven stores burnt, nine vessels damaged, and over one hundred thousand dollars worth of merchandise destroyed. Public Thanksgiving was held this year on the same day in Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland, Virginia, North Carolina, Georgia, Alabama, Florida, Mississippi, Louisiana, Arkansas, Tennessee, Kentucky, Missouri, Wisconsin, Iowa, Illinois, Indiana, Michigan, Ohio, and Texas.
