AMERICA. ARRIVAL OF THE NIAGARA  The Royal Mail steamer Niagara arrived here yesterday afternoon, with Boston dates to the 6th inst., 76 passengers, and 31,250 dollars in specie. The advices from Washington contain information relative to important movements on the part of the government with reference to the difficulties with Nicaragua. -Mr. Runnels, the -newly appointed. Consul at San Juan del Sur, had left for Central America, with despatches to Gen. Lamar, and the commanders of the Home and Pacific squadrons. The instructions sent out to these agents of the government are said to be of a peremptory character, arid such as will hasten a settlement of the questions pending betweem the two republics. It is reported that an opinion has been expressed in official quarters that a necessity for an extra session of Congress'may occur, owing to the condition of the foreign relations. The New York herald of the sth inst. says: "A special messenger leaves to-day, by the steamer for Aspinwall, with instructions for General Lamar and the commoflores of our Home and Pacific squadrons ; and should the private accounts that have been received in relation to the recent negotiations in Nicaragua turn out to be correct, that government, as well as the others in Central America, will soon find out that there is some other power in the world than that wielded by the Anglo-French alliance. In view. of the possible necessities that may grow out of the complicated state of affairs in the may of Mexico and the Caribbean Sea, orders have been sent to the several navy yards to prepare a large number of. vessels for immediate service. In taking this energetic and prompt course Mr. Buchanan has exhibited a clear conception of the true character of those irresponsible institutions called governments in Central America, and if our diplomatic representatives there comprehend the President's views, and _do not permit themselves to be humbugged by diplomatic palaver, they will soon bring the unscrupulous rulers of those republics to a sense of the fact that there are rights which must be respected, and which they must respect. An energetic demonstration now, insisting upon the immediate recognition of the claims of our citizens, and a disposition to do them justice, will have a greater effect upon the unwise rulers of those States than even a declaration of war would at a later period, and will doubtless save us from such a resort. The course Mr. Buchanan has determined to pursue is just what was required in the present emergency, and we have no doubt will bring President Martinez to his senses." The trial of the Hon. Daniel E. Sickles, 'who is charged with the homicide of Philip Barton Key, on the 27th of February last, was commenced in the Criminal Court at Washington on the 4th. The court was crowded with spectators. 'The demeanour of Mr. Sickles was characterised by his habitual self-. pos - The election in Connecticut for State officers, members of Congress and the Legislature, took place on the 4th, and resulted in the complete success of the republicans. The steamship Cahawba arrived at New York on the 4th, with advices from Havannah to the 30th ult. The war steamer Francisco de Asis had landed General Planar, second in command to the Captain General. The city was healthy, but the fashionable season having ended, visitors were coming north. The Prussian war frigate Geffion sailed for New York on the same day as the Cahawba, having a German Prince on board, whose name is not given. The Prussian Consul at New York, Mr. John W. Schmidt, states that the vessel is on her way home from a scientific cruise, and he is not aware of any distinguished visitor on board, unless her captain  may be the Prince alluded to. The British flag-ship Irdus was at Havannah. Sugars were very dull, with two hundred and seveh thousand boxes on hand. There was a rumour that several sugar cane fields were on fire in different parts of the island. Freights had slightly improved. Our New York commercial advices state that business continued moderate in most departments of, trade, and not sufficiently active to call into request the large amount of unemployed capital in the market. The supply of money continued to increase, and the market favoured the borrower. Sterling exchange was firm at 1094 to 109;1. There had been a lull in the New York Cotton Alarket, caused by the advices of the Persia, which contained the announcement of a decline in the Liverpool market. Before the steamer sailed, however, holders submitted to a reduction of ic per lb., and a fair business was done at this decline. Middling Uplands, on the spot, were quoted at 121 c per lb.
