Cyclopedia of architecture, carpentry, and building : a general reference work .... gh4, 8, 2 and 1 in the larger cone, at b, e, d and e radial line through 6 intersects radial lines in the larger coneaty, li, i,j and the base line at k, while the radial line drawnthrough the point 7, intersects the radial lines of the larger coneat I and m and the base at n. We know that the line Da and E6>of the smaller cone intersect the larger cone at points a and o re-spectively, and determine the true points of intersection; these areshown in plan by a and o, and therefore no horizontal sectionsare required on these two planes. For the horizontal section onthe plane h c, drop vertical lines from the intersections b, c and don the radial lines, intersecting radial lines having similar num-bers in plan as shown by b\ c and d. To obtain the point of in-tersection in plan of e in elevation, draw from the point e a hori-zontal line intersecting the side of the cone at e^^ from which pointdrop a perpendicular line intersecting the center line in plan at e^ 52 n 3:. .J TINSMITHIXG Then rising F<;^ as radius, describe an arc intersecting the radialline 1 at e. Through the points e, d, c and h draw a curvedline, which is the half horizontal section of 5 6 in elevation. Inthe same manner obtain the sections shown in plan by f, h\ i, /and I; and 7, m and ^2., which have similar letters and fio-ures ipboth plan and elevation. The next step is to obtain the intersec-tions where the radial lines of the smaller cone will intersect thesesections in plan Just obtained. To avoid a confusion of lineswhich would otherwise occur, a reproduction of the plan and ele-vation has been transferred to Plate II. PLATE n. The figures on this plate are similar to those on Plate I andhave similar letters and figures; those letters and fio-ures beino-omitted which are not necessary. This plate should be studiedcarefully before proceeding. The reproducing from Plate leanbe best done by
