Other ruins exist in the island, one or two of which are described. “Some are close upon the sea-shore, others are on the tops of solitary hills, and some are found on plateaus or cleared spaces far inland, but commanding views of the sea. One of the latter kind is a congeries of ruinous heaps of square stones, covering at least five or six acres. It is situated on a piece of table-land, surrounded by dense forest growths, and itself covered with low jungle. There is the appearance of a ditch, in the form of a cross, at the intersecting angles of which are tall mounds of ruin, of which the original form is now undistinguishable beyond the fact that the basements, constructed of large stones, indicate that the structures were square. The natives can not be induced to go near this place, although it abounds in wild pigeons, which they are extremely fond of hunting.” These ruined structures were not built by barbarous people such as now inhabit the island of Ascension. There is no tradition relating to their origin or history among the present inhabitants, who, it is said, attribute them to “mauli,” evil spirits. The “great temple” was occupied for a time, “several generations ago,” according to the natives, by the shipwrecked crew of a Spanish buccaneer; and relics of these outlaws are still found in its vaults, which they used as storehouses. On many low islands of the Marshall and Gilbert groups are curious pyramids, tall and slender, built of stones. The natives regard them with superstitious fear. The author of these papers, being a mariner, suggests that they are “landmarks or relics of ancient copper-colored voyagers of the Polynesian race during their great migrations.” Remarkable structures of this kind are found on Tapituea, one of the Kingsmill islands, and on Tinian, one of the Ladrones, where, also, remarkable Cyclopean structures are found. They are solid, truncated pyramidal columns, generally about twenty feet high and ten feet square at the base. The monuments on Tinian were seen by M. Arago, who accompanied Bougainville. According to his description they form two long colonnades, the two rows being thirty feet apart, and seeming to have once been connected by something like roofing. On Swallow’s Island, some twelve degrees eastward of Tapituea, is a pyramid similar in construction; and on the west side of this island is “a vast quadrangular inclosure of stone, containing several mounds, or probably edifices of some kind, of which the form and contents are not known by reason of their being buried under drift-sand and guano.”
