The upper layers of potsherds in the kiln stratum of our Flood-pit consisted entirely ofJamdat Nasr ware. Above the kiln stratum lay the ruins of houses, and the three lowest layers of these also belonged to the same period as was proved by the pottery in them and, more particularly, by the occurrence in the third level from the bottom of a curious rough hand-made bowl which has since been found on a number of other sites and is a sort of hall-mark of the Jamdat Nasr potter: The mass of potsherds accumulated on the kiln site and the three building-levels on the top of them together testify to a reasonably long period ofJamdat Nasr occupation; to that occupation, fortunately, the sherds are not the only witness.
