Nikita, a village at the N.E. angle of the Toronaic Gulf. It is scattered over a chasm worked in a hill of sand, which rests against a rock of the most singular character and appearance; it is sparkling schist, cut out into grotesque forms. It is sometimes white, sometimes light blue. The skirt of the wood comes over the edge of the hill behind. The ruins of 280 houses are fancifully placed along the steep sides or on the terraces, or are concealed by orchards at the bottom of the chasm. On the side of the hill, in a small enclosure which once surrounded the church, stand seven white columns close together. The enclosure itself is nearly undermined, and below it hangs a column suspended across the road, laving been caught or sustained by the bushes on each side.
