in the country districts has been obstructed by heavy falls of snow. Further Indian difficulties have occurred on the Klamath river. An Indian was shot at Happy Camp for stealing a knife, and, in revenge, a miner who was supposed to have killed him, was shot by the Indians. The whites soon after collected a large company, and on the 12th surrounded all the Indian lodges at the Indian ferry, and shot all the men, with several squaws, and destroyed the rancho. A similar scene occurred two miles above. About thirty or forty Indians were killed. SANDWICH ISLANDS. We have news from Honolulu to the 13th of March. An act has been passed by the Hawaiian Parliament admitting all flour, fish, coal, lumber, staves and heading from the United States, into the Islands free of all duty, provided the government of the United States will admit the sugar, syrup, molasses, and coffee of the Hawaiian Kingdom into all United States ports on the same terms. The volcano of Mauna Loa is in a state of renewed activity. The eruption is described as one of the finest ever witnessed. A jet of molten lava, a hundred feet in diameter, is hurled five hundred feet into the air, and on falling, sweeps its fiery course toward the sea. The stream has filled up ravines, and swept away forests. The altitude of the present eruption is about ten thousand feet above the level of the sea. SOUTH AMERICA. The news of the downfall of Rosas is fully confirmed, and the dethroned despot had reached Great Britain. We have further details of the decisive battle at Santos Lugares, which was far less bloody than was originally represented. Rosas had collected in the intrenched camp there about 20,000 men, of whom the great majority were entirely inefficient, and none were under proper organization. The vanguard composed of 5000 men under General Pacheco was dispersed and driven back by Urquiza upon the intrenchments, and three days after, the whole army of Urquiza offered battle in front of the fortifications. The two armies were about equal in numbers--the attack being general throughout the whole line, which extended over six miles. Rosas, finding that there was very great disaffection among his own troops, seems to have abandoned the contest at an early stage, and to have sought personal safety in flight. He left the centre of his line, composed of picked infantry and artillery, under the command of Chilavert, a deserter from Urquiza's army, but a man of undaunted courage. This was the only part of Rosas' army which maintained the fight. When it was routed, Chilavert was taken prisoner and immediately shot as a deserter. The news of the result had been received with unusual satisfaction. One of the earliest acts of the new Government was to appoint new justices of the peace, both for Buenos Ayres and for the country districts. A general amnesty had been proclaimed. Decrees had been issued restoring to their owners, houses and other property which Rosas had confiscated.
