In Ibn Haukal's map, although we have very little indication of comparative distance, we have a rough idea of bearings, and the invaluable datum of a fixed starting-point that can be identified beyond doubt. The great Arab port on the Makran coast, sometimes even called the capital of Makran, was Tiz; and Tiz is a well-known coast village to this day. About 100 miles west of the port of Gwadur there is a convenient and sheltered harbour for coast shipping, and on the shores of it there was a telegraph station of the Persian Gulf line called Charbar. The telegraph station occupied the extremity of the eastern horn of the bay, and was separated inland by some few miles of sandy waste from a low band of coarse conglomerate hills, which conceal amongst them a narrow valley, containing all that is left of the ancient port of Tiz. If you take a boat from Charbar point, and, coasting up the bay, land at the mouth of this valley, you will first of all be confronted by a picturesque little Persian fort perched on the rocks on either hand, and absolutely blocking the entrance to the valley. This fort was built, or at least renewed, in the days of General Sir F. Goldsmid's Seistan mission, to emphasize the fact that the Persian Government claimed that valley for its own. About a mile above the fort there exists a squalid little fishing village, the inhabitants of which spend their spare moments (and they have many of them) in making those palm mats which enter so largely into the house architecture of the coast villages, as they sit beneath the shade of one or two remarkably fine "banian" trees. The valley is narrow and close, and the ruins of Tiz, extending on both sides the village, are packed close together in enormous heaps of debris, so covered with broken pottery as to suggest the idea that the inhabitants of old Tiz must have once devoted themselves entirely to the production of ceramic art ware. Every heavy shower of rain washes out fragments of new curiosities in glass and china. Here may be found large quantities of an antique form of glass, the secret of the manufacture of which has (according to Venetian experts) long passed away, only to be lately rediscovered. It takes the shape of bangles chiefly, and in this form may be dug up in almost any of the recognized sites of ancient coast towns along the Makran and Persian coasts. It is apparently of Egyptian origin, and was brought to the coast in Arab ships. Here also is to be found much of a special class of pottery, of very fine texture, and usually finished with a light sage-green glaze, which appears to me to be peculiarly Arabic, but of which I have yet to learn the full history. It is well known in Afghanistan, where it is said to possess the property of detecting poison by cracking under it, but even there it is no modern importation. This is the celadon to which reference has already been made. The rocky cliffs on either side
