A treatise on concrete, plain and reinforced : materials, construction, and design of concrete and reinforced concrete; 2nd ed. . sented in cross section in Fig. 199, page 627. This is the main domeof the Temple Adath Israel at Boston, Mass., designed and built by Mr. Norcross, under the supervision of Mr. C. H. Blackall, Architect. The dome proper, which has a span of 52 feet 9 inches, is 5 inches thickat tlie haunch and 3 inches thick at the crown, and is composed of i : 2 : 4broken stone concrete. The reinforcement consists of expanded metal,3-inch mesh No. 10 gage, from the tension ring to the angle of rupture, and2-inch mesh No. 12 gage for the remainder of the section. The 5 by 4 by^-inch angle tension ring is supported by 4 by 3 by f inch angle struts, oneon each side of all the haunch windows, which in turn carry the weight ofthedome to the steel girders of the roof below. In designing the dome, the stresses were computed by Prof. WiUiam Cains CONCRETE BUILDIXG CONSTRUCTION 627 analytical method,* the essential features being somewhat similar to theHabrich Construction as applied to domes in EXPANDED METAL2 MESH *I2 OAUQE EXPANDED METAL3mesh .*IOGAUQE SECTION BETWEEN WINDOWS T - SECTION THROUGH WINDOWS Fig. 199. Dome of Temple Adath Israel, Boston. (See p. 616.) WALLS OF MORTAR PLASTERED UPON METAL LATH Partitions of plaster from metal lathing are used extensively for fire-proof office buildings and hotels, and are also adapted, when made withPortland cement mortar, to certain classes of outside walls. For a one-stor} building, timber or steel posts may be set upon concretefoundations, and the walls constructed by using f-inch or i-inch channelirons for studding, to which the metal lathing is attached, and then covered(on both sides) with Portland cement mortar about 2 inches thick, the stud-ding being generally set from 12 to 16 inches on centers, the spacing de-pending on the height of wall. Such walls are also adapted for highbuildings where
