- A small cemetery of 104 Early Dynastic, Dynasty 1, graves was excavated: "At this end the cemetery (of Lahun) is much earlier than the rest, and is close to the station of Bashkatib, it is here named from that, to distinguish it. ... Though this cemetery is not extensive, only 104 graves being noted, and several of those entirely bare, it is yet important for its short period-of the first three dynasties". These were numbered between 700 and 804.
- Middle Kingdom mastabas were explored : numbered 620, 608, 609, 601, 607, 618 and 905. Other Middle kingdom tombs were published in detail: 107 (wady), 602 (on the West Ridge), 603, 608, 610, 650, 651-659, 904, 906, and 913
Some objects from this season of work (along with Harageh, Lahun, Gurob and Sedment) were distributed after the Second World War in 1948 and 1949 by Hilda Petrie having been stored at University College London. In these cases it is not always clear which tomb the material is from, although the objects were (according to Hilda Petrie) distinguished by site with the use of letters: H, L, G and S, corresponding to the different sites.
