On the 2d of July, 1861, I sailed from New York City on a little brig, the "Ocean Eagle," with destination to the island of Corisco, near the equator, on the West Coast of Africa. My first introduction to the natives of Africa was a month later, when the vessel stopped at Monrovia, the capital of the Liberian Republic, to land a portion of its trade goods, and at other ports of Liberia, Sinoe, and Cape Palmas; thence to Corisco on September 12.
