Not far from the Giant's Grave, as this site is locally called, is another relic of hoary antiquity, in the shape of a tumulus, which, when opened, laid bare a kistvaen, or sepulchral chamber, formed of a great block of granite, weighing nearly five tons, resting on two upright granite slabs, and enclosing a space about six feet square. This method of burial is well known throughout the old world; such burial chambers have been found in Greece, and in considerable numbers in Ireland, where they are primitive Celtic. In the Lundy kistvaen no skeleton was found, nor anything, indeed, save a small fragment of pottery, though "there was a rank odour in the cavity, very different from that of newly turned earth." There is a logan-stone on the eastern side of the island, which, within the memory of Mr. Heaven, the last owner of the island, was a true logan-stone, and could be rocked with the hands, but has now slipped from its socket. But the whole question of these logan-stones is controversial, some claiming them as relics of antiquity of whose use and meaning we are ignorant, and others as the chance product of the natural forces of rain and weather. The same also may be said of the "rock-basins," of which a very perfect example may be found in the Punchbowl Valley, being a granite basin of four feet in diameter, with a uniform thickness of six inches, with both the concave and convex surfaces segments of a perfect sphere. Later opinion inclines to a human, and not a chance, origin for these interesting phenomena. But, leaving the dim and still conjectural paths of archaeology, let us turn to the history of Lundy. Here again we are confronted with facts which a conscientious historian would hesitate to assert, save as legend. For this singular land, where the King's writ does not run, which is not assimilated even yet to municipal government, was for centuries, even down to the eighteenth century, a robber stronghold, from which, as from those castles on the Rhine, and still earlier and more powerful castles of the Aegean lords, built athwart the peninsulas of the trade-routes, the garrison swooped maraudering upon the peaceful occupations of unprotected folk.
