Note 4 — Chapter V · Megalithic Monuments.

Dolmens are scattered about in great numbers in the Kouban basin and all along the coasts of the Black Sea occupied by the Tcherkesses. These curious vestiges of an unknown civilization are still an unsolved enigma to us, as are those of Western Europe; they are generally formed of four upright slabs surmounted by a fifth laid horizontally, and one of the supporting slabs is nearly always pierced with a small round or oval opening. Excavations have brought to light arrow-heads, rings, and bronze spirals, but Chantre, an authority of considerable weight, and who has moreover had the advantage of actually seeing these megalithic monuments of the south of Russia, attributes the objects found beneath them to secondary interments, and does not hesitate in assigning the more ancient monuments themselves to the Stone age. We must not omit to mention the dolmens found in the southern portion of the island of Yezo (Japan),4 nor that described by Darwin at Puerto Deseado (Patagonia). They are both very similar to those of Europe.
