Wood was used for buildings and parts of buildings, for furniture, boxes, barrels, chariots, traveling cars, palanquins, coffins, statues, statuettes, and in boat-building. "Regarding the methods of woodworking, certainly the axe was the primitive tool, as shown by the royal architect being designated by the axe. In the scenes of the pyramid age we find the saw about three feet long worked with both hands, the mallet and chisel for cutting mortise-holes, and the adze in constant use for shaping and for smoothing wood. To this day the small adze is a favorite tool of the Egyptian carpenter and boat-builder. For smoothing down the caulking inside a boat, heavy pounders of stone were used, held by a handle worked out on each side of the block. Drills were also commonly used both on wood and stone, worked by a bow."[38] As they had only the hand-saw, in making planks they usually placed the piece of timber upright and fastened it to stakes and then sawed downward through it. In joining two boards end to end, they would cut into their ends and join them and glue them and then insert a flat wooden pin through them from edge to edge and then pass a round wooden pin through the boards into the flat pin, thus effectually keeping the joints from opening and thereby showing the thoroughness of their work. They dovetailed and veneered and stained and painted and gilded and inlaid their woodwork, thus displaying a high degree of skill in working with wood. One of the greatest industries with them was that of brick-making, which was wholly under the control of the government and carried on solely by it. "The use of crude bricks baked in the sun was universal throughout the country for private and for many public buildings, and the dry climate of Egypt was peculiarly suited to those simple materials. They had the recommendation of cheapness, and even of durability; and those made 3,000 years ago, whether with or 'without straw,' are even now as firm and fit for use as when first put up in the reigns of the Amunophs and Thothmes, whose names they bear. When made of the Nile mud, or alluvial deposit, they required straw to prevent their cracking; but those formed of clay (now called _Háybeh_) taken from the torrent beds on the edge of the desert, held together without straw; and crude brick walls frequently had the additional security of a layer of reeds or sticks placed at intervals to act as binders."[39] The tanning and preparation and use of leather was quite a leading industry of ancient Egypt, so much so that a section of the city of Thebes was set apart for the exclusive use of the workers in skins and leather. The demand for leather was so great Egypt itself could not supply the hides necessary and great quantities of hides were imported from foreign countries and also the skins of wild animals were brought in and used. They tanned the skins and dyed them and made some fine leather and also embossed the leather.
