A bill to remove the State Capital from San José to Vallejo has passed the Senate, but has not been acted upon in the House. A project has been started for a railroad from San José to San Francisco. The receipts into the city treasury of San Francisco, for the quarter ending Nov. 30, were $426,076, and the expenditures $638,522. The total debt of the city was $536,493. No election for U. S.

An expedition was dispatched toward the close of October to explore the Colorado River from its mouth.

It is entitled the "Awakener of Patriotism," and narrates the history of the late war with the United States. Hostilities have broken out between the central Government of Guatemala on the one hand, and the allied States of San Salvador and Honduras on the other. A battle took place on the 21st of January at a village called San José, when the forces of San Salvador and Honduras were totally routed, and fled in every direction, closely pursued by the victors. Such, at least, is the Guatemalan account, which is the only one that has yet reached us.
