Report of the Naval committee to the House of representatives, August, 1850, in favor of the establishment of a line of mail steamships to the western coast of Africa, and thence via the Mediterranean to London; . he shape of huge blocksof lava, and cinders. Here the vegetation began to thinout, the pines disappearing, but the spruces still keepingon, though the trees were smaller ?nd less numerous thanlower down.
