RETURN TO LOANDA--CYCLOPS LEAVES THE COAST--HON. CAPTAIN HASTINGS--DISCUSSION WITH THE BRITISH COMMODORE IN REFERENCE TO THE VISIT AT ST. HELENA--COMMODORE FANSHAWE--ARRIVAL AT MONROVIA--BRITISH CRUISER ON SHORE--ARRIVAL AT PORTO PRAYA--WRECK OF A HAMBURGH SHIP. The Perry, after ten days’ acquaintance and intercourse with many exceedingly kind and hospitable friends, reluctantly sailed for the African coast, and after a passage of ten days, beat up inside of the reef forming the harbor, guided by the signal-lights of the men-of-war, and anchored at Loanda. The following morning, salutes were exchanged with the French commodore, whose broad pendant was flying at the main of a fine steam-frigate. To the Secretary of the Navy it was announced that no suspicious American vessel had been on the south coast since the capture of the Chatsworth. After remaining two days in Loanda, cruising was renewed, in company with the Cyclops, off Ambriz. Soon afterwards the Cyclops was ordered to England. The commanding officer of the southern division was now about taking his leave of the coast. The Hon. Captain Hastings (since deceased), brother to the Earl of Huntington, was an officer of great merit, and a man of noble qualities. He was ever kind and attentive to the wants of his crew. He possessed great moral integrity of character, and sound religious principles. Notwithstanding the protracted correspondence, often involving delicate points and perplexing questions, the social friendly intercourse between the two commanders in the different services had not for a moment been interrupted. On parting the two vessels exchanged three hearty cheers. The Perry beat up to the southward as far as Benguela, and looking into the harbor, without anchoring, proceeded to run down the coast to the northward. On approaching a Portuguese man-of-war, that vessel fired a blank cartridge from a small gun. It being daylight, and the character of both cruisers easily discernible, the object of the fire could not be conceived. A thirty-two pound shot was immediately thrown across the cruiser’s bows. She then hauled down her colors, but soon afterwards hoisted them. A boat was sent for an explanation. The officer was assured that the Perry, in coming bows on, had been mistaken for a Portuguese brig, of which the cruiser was in search.
