The Neolithic deposits are most accessible in the temple area, our Area F, at the northwest side of the site, because the earlier excavations removed later deposits from above them. Trenches F5-F8 were subsequently combined and designated F101. This was cleared of the debris that had accumulated since then and new soundings were made. The results generally confirmed the findings of the earlier expedition, as recorded in the notebook of Virginia Grace in 1931. By the end of the season all trenches in Area F except F1 were linked to one another, giving a total area of Neolithic exposure of more than 200 square meters.
Several cuttings are visible in the bedrock.
Our excavations have now produced a reasonably complete sampling of the Neolithic sequence as it survives at Halai. Some stone walls still stand to heights of 1 m. or so. House plans are generally rectilinear . The best preserved room plan is that of Room 11, near the middle of trench F9, which was initially excavated in 1931 by Virginia Grace. Most of the structures shown in schematic form in Figures 4 and 5 are parts of similar rectangular rooms and houses.
