Supplies to a limited amount, together with teachers and mechanics, are to be provided for them by the United States Government. The tide of emigration has begun to set once more strongly toward Oregon. A late arrival brought out six female teachers sent under the auspices of a society at the East. Discoveries of coal have been made at various points along the Pacific coast. Steam communication has been established between the mouth of the Columbia and the Willamette. SOUTHERN AMERICA. In MEXICO Congress has been endeavoring to devise some means to raise funds to meet the current expenses of Government. Among other expedients it was proposed to withhold from the public creditors the balance of the United States indemnity remaining in the treasury, and to impose indirect contributions on the departments. An unsuccessful attempt was made to invest the President with full powers to raise funds as he could, without the concurrence of the legislative authority. Congress, however, adjourned on the 23d of May, leaving affairs in the utmost confusion and uncertainty. The late resignation of Señor Esteva, the Minister of Finance, was occasioned by his inability, from want of funds, to effect the consolidation of the interior debt. He wished the indemnity to be withheld from the public creditors, and a suspension of payments till 1852 to be decreed. The Indians in Yucatan have suffered severe checks, and are giving up hostilities. Claims to a large amount have been presented against the Government of the United States, for damages arising from failure to prevent Indian depredations, according to the stipulations of the treaty. In BRAZIL warlike preparations are still carried on against Buenos Ayres, or rather against Rosas, the President, who has made himself especially obnoxious to all the States on the Parana. Little apprehensions of actual hostilities are entertained. In PERU Gen. Echenique, who had been chosen President by 2392 out of 3804 votes, entered upon his office on the 20th of April. He is the first President who has attained the post by election; his predecessors owing their elevation to the sword. He nominated Gen. Vivanco, his principal opponent, as Minister to Washington, perhaps as a kind of honorable banishment. The appointment was declined. An insurrection was attempted, and Vivanco was named by the insurgents as their leader, apparently without his direct concurrence. He was, however, arrested and imprisoned.
