(32) The obelisks of Ḥatshepsôwet were mounted on sleds, perhaps to make an easier running surface; it would also serve to damp any shocks and to distribute the upward pressure of the rollers evenly along the under surface of the obelisk. The method of attachment is shewn in figure 7 (from NAVILLE, _The Temple of Deir el Bahari_, Part VI, pl. CLIV), but is rather vague. I cannot say whether the Aswân obelisk was to have been mounted in this way or not; if it were, then it would be put on its sledge at the same time as it was put on the rollers, as explained in the last section. [Illustration: Fig. 7.—Ḥatshepsôwet’s obelisk on sled.] (33) Once on its rollers, there is a fairly level and straight track from the mouth of the valley running along the course of the old barrage railway (pl. VII), joining the two large embankments D⁠E and F⁠G, which feed the quarries on the south of the obelisk and on the high desert respectively. Plate IV, no. 4, gives a view of the embankment F⁠G looking down to Aswân town. It joins the course the obelisk would take at A. The modern town north of the station prevents us determining exactly where these embankments gave on to the river bank. (34) On the details of the boats, on which we know the obelisks were transported, I can offer no opinion of value, as I am not familiar with boat design, particularly that of the “queen-truss” type which seems to have been so popular with the Egyptians. I will content myself, therefore, with citing certain accounts and giving sundry references, which may prove of use to those who intend to pursue this matter further. The only scene we have of water transportation is that of the temple of Dêr el-Baḥari, published by Naville and entitled _The Temple of Deir el Bahari_, Part VI, plate CLIV, where there is a picture of the boat containing _two_ 30‐metre obelisks placed butt to butt[12]. The boat used here must have been at least 82 metres long. He mentions also the boat used to carry the two obelisks of Tuthmôsis I, which measured 63 metres by 21 wide (BREASTED, _Ancient Records_, II, 105). Both this boat and that of Ḥatshepsôwet are spoken of as the “August” boat. {33} [12] It has been suggested that the two obelisks shewn butt to butt in the Dêr el-Baḥari sculpture were not the Karnak pair, but those erected before the Dêr el-Baḥari temple. Excavation has not confirmed this. The subject is discussed by Breasted in _Ancient Records_, II, p. 135, note _e_. Another great boat was made by one Uni, in the VI^{th} dynasty, for the transport of stone from Aswân. This measured 60 cubits (31 metres) in length by 30 in width, and took only 17 days to construct (_Ancient Records_, I, 322).
