e design may readily be put infrom the lines, curves and centers given. The example shown at Fig. 230 illustrates anelaborate design suited for a balustrade andmany other purposes. Let a b be the height;divide this into two equal parts in the point c,through c, draw a line at right angles to a b, asd c d. Draw the distance a b, into eighteen, ora c, into nine equal parts. With one of.these,from the center c, describe the circle e, f, g,h, and from the point where this cuts the line,a b; d, d, describe circles, the radius of whichis one-fourth of one of the parts, or a, c. Thenwith the distance as h, g, from these points ascenters, describe arcs cutting in the point i;from i, as a center with e, the same radius stillkept on the compasses, describe an arc j. Dothe same from the other points, as g, f; f, e; e,h, and thus find the centers from which the arcscorresponding to j, are described.

Next, from i,set off to the point p, and do the same at theother and corresponding points, thus finding thefour centers m, n, o, and p. From these, withe, c, d, or i, j, as radius, describe arcs which arejoined by straight lines with the semicircles w,and X, at the upper and lower ends of the design.To find the centers of these semicircles, dividethe distance between the points I, and 2, on theline a b, into four equal parts, and at the pointsdraw a line z, z; from the point y set off in theline z z, a distance equal to b g, to the points aand b. From these points a and b with a radiusequal to y, I, or y, 2, describe semicircles, as w,c; X, c. Join the points w, and x, by straightlines e, e, with the arcs described from the pointsp, and n.
