It is about six times as large as the lake of Geneva, having an area of some 1300 square miles. Its western shore is erroneously laid down in existing maps; and this necessitated a particular survey of that region during my second journey, the result of which has been to invest the lake with a shape of greater symmetry--a central body with two arms, one on the north-east, the other on the south-west. The remainder of the outline I have borrowed from the best available sources, adapting them to the position of Van, of which the latitude and longitude are approximately known, and correcting them as well as possible by sketches, and readings to the principal points from the summit of Sipan. If my reader will turn to the map which accompanies this work he will, I think, be able to transfer, with the aid of a few illustrations, the features which are there conventionally delineated into a picture visible by the mind's eye. How strange it seems that at the end of the nineteenth century one should be engaged in exploring and mapping this fine country, one of the fairest and most favoured of the Old World! How should we be able to explain, still less to justify, the circumstance to some visitor from another planet? It lies about in the centre of the land area of our hemisphere; the climate is bracing, water is abundant, the sun is warm. Yet it is so little known to the more civilised peoples that their travellers journey thither with the aid of a compass through districts which are now deserts, but which are well capable of supporting the races that are highest in the human scale. The case would appear to have been much the same during the period of the expansion of Greek culture and of the later and beneficent sway of Rome. The knowledge displayed of these regions by representative writers like Strabo, Pliny and Ptolemy is, to say the best of it, vague and fabulous. Yet Strabo, the contemporary of Augustus, was a native of Asia Minor; the countrymen of Pliny had carried the Roman eagles to the Araxes; and Ptolemy wrote during the reign of the Emperor Hadrian whose statue, commemorating his journey through the interior, looked out upon the waves above Trebizond. The first of these authorities plainly confuses the position of Lake Urmi with that of Lake Van; but he is well acquainted with the essential characteristics of both sheets of water, different and strongly marked as these are. The former is described as largest in area, and second in size to the sea of Azof; its name is interpreted to signify the deep blue (kyanê hermêneutheisa). The water is salt; and there are salt works in the neighbourhood. [25] The peculiar properties which actually distinguish the latter exactly tally with the language of Strabo, who, speaking next of the lake Arsene or Thopitis, says that it is charged with nitre, which word would seem with him to signify carbonate of soda, [26] and that it washes clothes as though they had been scoured. He
