THE EGYPTIAN SUDAN thoroughness and zeal, and his king gave him a new proof of the confidence which he placed in him by sending him to the country of Abhat, to obtain for him a stone sarcophagus, with its cover, and a little pyramid. He was next sent to Elephantine Island for the granite which was required in the building of his sovereign's pyramid at Sakkara called Kha-nefer. To transport the granite he took with him six large broad-beamed boats, three barges of the kind called sath, and three other barges of another kind, the whole being protected by one " war-boat." Una tells us that work on such a large scale had never been done at Abhat and Elephantine Island with only one war-boat to protect the workmen, and the stones, and the boats, and we may therefore conclude that the fame of the five expeditions which he had made to the south had produced a good effect throughout the country. His next duty was to go to the quarries at Het-nub (Alabastronpolis), and hew out a table for the offerings which would be made in the king's tomb ; the work of quarrying the slab and floating it down to Memphis occupied seventeen days. Una next superintended the building of a large usekht boat, 60 cubits long, and 30 cubits wide, and he managed to bring it down the Nile in seventeen days during the third month of summer (June-July), although the river was very low.

Una's next labour was a very important one, for his king sent him to the south to dig out five lakes, or canals (?), which were to be used in connection with the floating of stone down the river. Where these lakes or canals were made is unknown, but it is most probable that they were in the First Cataract, and that they were intended to facilitate the passage of broad-beamed barges and rafts through the Cataract at low Nile. This work being completed, Una went on to the country of Uauat, in order to build three usekht barges, and three sath barges of the acacia trees which grew there. When he told the local chiefs the object of his mission they made the people of Arthet, Uauat, Amam, and Metcha bring wood, and the barges were built in one year. Taking advantage, no doubt, of the high Nile, Una floated his empty barges and rafts through the Cataracts, and, having loaded them with granite at Elephantine, let the river carry them down to Memphis. Now these facts are important, for they prove that 518
