On Wednesday, June 15th, we raised a strange sail to leeward. Running down to her, we found it to be the bark “Empress,” a Peruvian merchantman, from Cumsingmoon, China, to Callao, with four hundred Chinese coolies on board, bound to the mines in Peru. This system of deception is equaled only by the African slave-trade. The Chinese (who are generally of the lower classes) are allured, by flattering inducements, to go to California, or some other equally rich country, where, they are told, they will become rich in a few years, and can return to their own country. As soon as they get them on shipboard, a guard is stationed over them, with orders to shoot down the first one that shows any signs of resistance. Being kept such close prisoners, and on the coarsest food, they are naturally joyous at the sight of land, and leave the vessel with glad hearts, only to enter the slavery of the Peruvian mines. This species of slave-trade is, like the African slave-trade in our own land, forbidden by the laws of the country, but secretly connived and winked at. “Ormsby’s Peak,” of which we give a sketch taken on shipboard, we saw on Saturday, June 18th. It rises about two hundred feet above the level of the ocean, and has no shallow shores around it. Soundings can not be obtained close to the rock. It is one of nature’s great curiosities. On Thursday, June 23d, we first raised the Bonin Islands, consisting of Perry’s Group, Peel’s and Bailey’s Islands. We here caught a green turtle, who was asleep upon the water. We soon had him in our coppers, making turtle-soup for all hands. The morning of Monday, June 27th, saw us close in to Peel’s Island. This island presents a fine appearance from the sea, the land being moderately high, and thickly covered with verdure. On the west side is a fine harbor with good anchorage, and very convenient for ships wishing to water. About 9 A.M. the wind died away, leaving it a dead, dull calm, and the current slowly drifted us toward the northern point of the island. As we neared the land destruction appeared almost inevitable, and we feared that the voyage of the “Emily Morgan” was about being brought to a sudden termination, leaving her bones to bleach upon the rocks. But an overruling Providence held all in His hands, and, when within a stone’s throw of the shore, we struck a westerly current, which swept us clear of the point. [Illustration: ORMSBY’S PEAK.]
