<STRONG>A Flight.</STRONG> — A continued series of steps without a break.
<STRONG>Axis.</STRONG> — In architecture an imaginary line through the center of a column, etc., or its geometrical representation; where different members are placed over each other so that the same vertical line on the elevation divides them equally, they are said to be on the same axis, although they may be on different planes; thus triglyphs and modillions are so arranged that one coincides with the axis or line of axis of each column; in like manner the windows or other openings in the several stories of a facade must all be in the same respective axis whether they are all of the same breadth or not. In geometry, the straight line in a plane figure about which it revolves to produce or generate a solid. In mechanics, the axis of a balance is the line upon which it moves or turns. In turning, an imaginary line passing longitudinally through the middle of the body to be turned, from one point to the other of the two cones, by which the work is suspended or between the back center and the center of the collar of the puppet which supports the end of the mandril at the chuck.
