AMERICA.  SOUTHAMPTON, MAY 4.  By the United States' mail steam-ship Washington, Capt. Cavendy, which arrived off Cowes this morning, en route from New York to Bremen, with the German, French, and English mails, we have dates from New York to the 19th tilt.  The Washington brings 183 passengers, and on freight about 150,000 cols. in specie, principally for Loudon, and the usual cargo. The Collins' mail steam ship Baltic arrived at Now York from Liverpool on the 18th ult.  The steam-ship G6orge Law, from -Aspinwall, with the semi-monthly mails and nearly 1,500;000 dols. in treasure from California, had arrived at New York. The Aspinwall Courier of the sth ult. states that Col. &Wessinger, at the head of 400 troops, was defeated near San Jose by 500 Costa Ricans, under Gen. Mora. Twenty Americans were taken prisoners and shot. 'rho Costa. Rican army was about to enter Nicaragua. The statements as to the result of the battle aro conflicting. The Washington correspondent of the New York fierald, in alluding to the Costa Rica war, say's— " That despatches from Col. Wheeler to the Govern. ment mention that Col. Sehlessinger'3 retreat was not a defeat of the Costa Ricans, but a stroke of successful policy, superinduced by the largely-overwhelming force of the enemy."  The same correspondent says-"Among the official documents received from Oregon is a letter from Joel Palmer' Superintendent of Indian Affairs, who, confirming the statements of Governor Curry, says, Toe present difficulty in Southern Oregon is wholly attributable to the acts of the white adding, cannot but feel it is our duty to a lopt such measures as will tend to secure the lives of these Indians, and maintain the guarantee secured by treaty stipulations. The future will prove that this war has been forced upon these Indians against their will, and that, too, by a set of reckless vagabonds, for pecuniary and politiCal objects, sanctioned by a numerous population who regard the Treasury of the United States as a legitimate object of plunder. The Indians in that district have been driven to desperation by acts of cruelty against their people. Treaties have been violated, and k ots of barbarity committed by those claiming to be citizens that would disgrace the most barbarous nations of the earth. If none but those who perpetrated such acts were to be affected by this ear we might look upon it with indifference ; but unhappily this is not the case.' "  Advices from Havannah are to the 11th ult. The man who attempted to take the life of the Archbishop of Cuba was to be garotted. The cause of the attempt is said to have arisen out of the denunciations of the archbishop from the pulpit of certain Spanish hidalgos, who were living in open concubinage with their own slaves. The aggregate number of Asiatic labourers which have arrived at the island since the importation commenced is 4,066. In addition 390 of the unfortunate creatures had been lost by disease, accidental drowning, and suicide before reaching Cuba. In the New York money trarketforeign exchange continued firm. Thu.() wore but few bills in the market, but with a continued large business in cotton at the southern ports tae market would ultimately become well supplied.

The stock market during the week was active, but subject to heavy/fluctuations. Government stocks were held at high rates and very little business was done. The cotton market continued firm, with sales of about 2,000 to 2,500 hales, closing at about 11c. to 114 e. for middling Uplands.
