The Daylamites up, came and joined us as we sat over our samovar in one of the half-buried, vaulted rooms. We could look out through its arched door into the hot daylight to the defile of the Naina Rud, and beyond and above to villages in two green islands on the slope, and to the stony reaches of Gavan Kuh, which lead to the Caspian. Another man soon dropped in from nowhere at all, and, sitting down in the friendly Eastern fashion, began to give at a great rate more information than we wanted.

Very little indeed is known about this country and there are many unidentified sites to be discovered in its recesses.
