 the south. Its principal wady with many small tributaries, drains the northern and eastern margins of the basin. The southern part supplies two main Wadys, one skirting the margin of the basin, and the other passing the village of Kannir, their confluence being due east of Caesarea.

From Cape Carmel to the Nahr ez Zerka, the delineation of the country has been very much altered by the Palestine Exploration Survey. For example, Sindianeh, ez Zerghaniyeh (Surganiyeh), Kh. Khudeirah (Gudara), Kannir (Kanir), and el Bureij, were all included in the basin of Nahr el Akhdar (now Nahr el Mefjir); whereas they belong to the more northerly basin of the Zerka. Koteineh appeared on the northern edge of the Zerka basin; it is now found on the northern edge of the Nahr ed Dufleh. Formerly the Dufleh basin was represented by Nahr Keraji which was supposed to be near Iksim (Ijzim). That village is now found to be in the basin of Wady el Matabin.

It is only just to the Palestine Exploration Fund's Survey, and at the same time an assistance to students, to unravel the tangled geography which route surveys, casual observations, and compilations from such materials have hitherto supplied. Transpositions from one basin to another, like that which has just been described in the connection with the Zerka and Mefjir, will be found repeatedly necessary in pursuing this account.



Under the name of Nahr Akhdar, this basin was supposed to have very narrow limits, the waterparting between it and the Mukutt'a basin, having been wrongly confined to two or three miles on either side of the village of Umm el Fahm. Its waterparting is now known to be coterminous, with that of the Mukutt'a from the north of Umm el Fahm (alt. 1,400 feet) to Tannin, a ruin on the south-east of Jenin, the direct distance exceeding 20 miles. At Tannin, the Mefjir
