A DoG-LEGGED Staircase Is One whlch has no opening or well-hole, and in whichthe rail and balusters of the progressive and returning flights fall in the same verticalplanes. The steps in it are fixed to strings, newel, and carriages, the ends of the steps ofthe inferior kind terminating only upon the side of the string without any housing. Y andZ in Jig. 782, are the plan and elevation of a staircase of this kind; AB is the lower newelwhereof the part BC is turned. On the plan, a is the seat of this newel. DE and FG inY are the lower and upper string boards framed into newels, KL is a joist framed into thetrimmer I. Ilie lines on the plan represent the faces of the steps in the elevation without.
