It was recommended, that from Monrovia he should proceed off from the coast, keeping well to the westward, until crossing the equator and reaching the southern limits of the cruising-ground, for the purpose of avoiding the prevailing winds and currents, which, south of the line, would be adverse to progress in-shore, but favorable to a close examination, on the return northward.

The object of the cruise was to protect the lawful commerce of the United States, and, under the laws of the United States, to prevent the flag and citizens of the United States from being engaged in the slave-trade; and to carry out, in good faith, the treaty stipulations between the United States and England.

After reaching the southern point of destination, or nearly so, the vessel was to cruise along the coast, examining the principal points, or slave-stations; such as the Salinas, Benguela, Loanda, Ambriz, River Congo, and intermediate places, back towards Monrovia: the commander acting in all cases according to the best of his judgment, upon the information he might obtain, and circumstances that might present themselves; taking care, in no case, to exceed the instructions of the Hon. Secretary of the Navy, furnished for his guidance.

Should British cruisers be met, he might act in concert with them, so far as the instructions permitted.

It was further noticed, that a number of suspected American vessels had been hovering on the coast, between Cape St. Mary’s and Cape Lopez, and that some of them had left the coast with slaves. Vessels clearly liable to capture and not provided with cargoes, might be sent directly to the United States. All captives found on board were to be landed at Monrovia.

The Perry left the Cape Verde Islands on the day in which her orders were issued, and arrived at Monrovia on the 20th. She there received provisions from the Yorktown, and sixteen Kroomen from the shore. Having exchanged salutes and visits of ceremony, she sailed on her southern cruise, and arrived at St. Philip de Benguela, after a passage of forty-one days, having, during the interval, boarded three legal traders. This passage was made on the port tack by standing to the southward and westward, into the southeast trades. But the passage from the north to the south coast should, in all cases, be made in-shore on the starboard tack; as will be explained, hereafter, during the third cruise of the Perry.

At Benguela, which is a Portuguese settlement, next in importance to St. Paul de Loanda, although now much dilapidated, and where the slave-trade has been carried on to a great extent, the customary exchange of a national salute and official visits was duly observed.

The commander ascertained, on his arrival, that the American merchant vessels were subject to greater restrictions than probably would have been the case had a man-of-war occasionally made her appearance in that quarter. He therefore intimated to the governor that our cruisers, in future, would visit that part of the coast more frequently than they had done for the last few years.

Information was received, that five days previous to the arrival of the Perry, an English cruiser had captured, near this place, a brig, with eight hundred slaves on board. In this case, it appeared that the vessel came from Rio de Janeiro, under American colors and papers, with an American captain and crew; and had been, when on the coast, transferred to a Brazilian captain and crew, the Americans having gone on shore with the papers. The captured slaver was sent to the Island of St. Helena for adjudication.

After remaining three days at Benguela, where neither fresh water nor provisions could be procured, the Perry weighed anchor and ran down the coast, examining all intermediate points, and boarding several vessels during the passage to Loanda. This city is the capital of Loango, and the most flourishing of the Portuguese establishments on the African coast.
