benefits resulting from this treaty, if the work shall be completed, will be of the most important character. As an auxiliary measure to the Nicaraguan Canal, it will tend very powerfully to unite the Atlantic and the Pacific states. * * * * * From CALIFORNIA we have intelligence to the 17th of June. San Francisco has been visited by two successive fires which had destroyed property to the amount of several millions of dollars. A large proportion of the goods burned were consigned by New York merchants to their agents in California, so that the loss will fall very heavily upon them. As insurance could not readily be effected the loss will be large. Nearly three millions of dollars in gold dust have reached the United States during the month. The foreigners resident in California had resisted the payment of the tax of twenty-five dollars per month levied by the state laws, and some difficulty was anticipated in enforcing payment, but at the latest accounts this had been obviated, and every thing was quiet. The intelligence from the mines encourages the belief that the quantity of gold dug this season will be greater than ever before. From the valleys of both the Sacramento and the San Joaquin very large amounts were constantly obtained, and new mines have been found as far north as Oregon, and as far south as Los Angelos. From the Mariposa mines many very beautiful specimens of the gold-bearing quartz have been procured. Difficulties had arisen with the Indians in different sections of the country, and several severe battles between them and detachments of U. S. troops had been fought. They grew mainly out of the hostile disposition of the Indians which is often excited and encouraged by the lawless conduct of the whites. Measures were in progress which, it was hoped, would restore quiet and security. It is stated that the property in San Francisco as assessed for taxation amounts to three hundred millions of dollars. * * * * *
