Floor arches

An arch dam, on the other hand, relies on its shape to withstand the pressure of the water behind it. The arch curves back upstream and the force exerted by the water is transferred through the dam into the river valley walls and to the river floor. They are normally constructed in deep gorges where the geological foundations are veiy sound. The United States s Hoover Dam is an example of a concrete arch dam.

The wider floor of tho retort is composed of throe parts, differing one from another in their construction —that is to say, the floor of the retort, which is formed by bricks on edge, is Beparatod from the fireplace by an arch of nine inches thickness, from the subsequent main flue by an arch of four inches and a half, and. from all the divided flues by flat bricks two inches and a half thick, And eight inches-long, laid in bix parallel rows, the joints of such rows corresponding to the centra line of five rows of pillars. 

One of the most recent improvements is that of Mr. Farthing, in which the kiln is heated by means of flues arranged under the floor, around the walls, and over the arch. By this means all deposit of dust or hard particles from the fuel on the surface of the glass is avoided, and any cheap kind of fuel may he employed. 

With this view the height of the slab or tablo is made exactly on a level with the floor of the arch, Its upper surface is flat and polished, to mould the lower surface of the mirror j and, before the casting, it is heated by hot coals spread over it, and then wiped porfectly clean. 

The Watergate is a three-arched loggia, whose floor is barely above the surface of the Rio San Remo at high tide. That night the tide was out, exposing a slippery carpet of weed on the watersteps. I topped up a lantern with enough oil to bum until dawn and hung it in the central arch. Then I went back in and shot all the bolts on the big doors. 

I fought him with a deadly desire to wound and be satisfied. I tore at his clothes and thumped him with my heels and fists, grabbed his short hair and twisted, tried to bite him, but he only laughed and clamped down harder, ground my head against the stone floor, and bit my breast until I howled with pain. Then he drove himself inside me and my legs opened wider, wider, my body arched, and I pounded my wrists in an ecstasy of sensation. But I was a divided Emilie—and one half looked on at this sensuous, thrashing creature and hated her.
