There is another great lake a long day’s journey westward from Iconium; its situation, however, is quite different from the foregoing, as it is well up in the western mountains, nearly four thousand feet above the sea. The town of Beyshehr, which gives its name to the lake, is found on its south-eastern corner; and the road thereto from Iconium passes by Fassiler, a place remarkable for its ancient monuments and the peculiar facial type of its inhabitants. Further to the north, and near the eastern border of the lake, is Eflatoun-Bunar, the site of a famous ‘Lycaonian’ structure called ‘Plato’s spring.’ With the tract westward of Konia, however, we have at present little concern,[65] and when we turn eastward we are inclined to regard the Hittite sites, whether along the edge of Taurus like Mahalich and Ivrîz, or isolated in the desert like Emir-Ghazi, as pertaining not to Konia, from which they are separated by desert, but to the same group as Tyana, with which they are to some extent geographically connected.

(_See p. 31._) ANATOLIAN HORSES: THE HALT AT NOONDAY (_See p. 39._)] This eastern group of sites, indeed, is remarkably linked together by a common river system. The centre is the ‘White Lake’ _Ak Geul_, at the foot of the Taurus, westward from Eregli, and southward from the desert ridge called Karaja Dagh, on the northern slopes of which is Emir-Ghazi.[66] This lake is of variable size. When overfull its surplus waters disappear in a hole that passes under the mountain; during the dry season, however, it becomes a marshy pond of stagnant water. Into this come three chief rivers. From the south-east the Ak Su, which rises in the main chain of Taurus, drains also the outlying spur known as the Kara Dagh, on the crest of which is Mahalich. Here also is Bin Bir Kilisse, ‘The Thousand and One Churches,’ an ancient site; while just to the north the isolated hill called Kizil Dagh rises from the plain. From the south-east there comes the Kodja Su from high in the Bulghar Dagh, flowing past Eregli, before which it is joined by a stream that with wonderful noise gushes forth in many points from the rock near the hamlet of Ivrîz, six or seven miles above the town. This source is called by the natives _Huda Verdi_, ‘God-has-given,’ in appreciation of a divine gift that transforms an arid corner of the desert into a garden-valley rich in fruit-trees and vines. Into the same lake from the north-east comes the Kizilja Su, after a sluggish journey across the eastern plains, fed in its course by many streams descending from the inner ranges of the Taurus. The head-waters of this river give life to a whole district of peculiar interest. The main stream rises just northward at Andaval, flowing past that village to Nigdeh and thence to Bor; just below here
