Fig. 47.—Section through a retaining wall and the soil it holds in place, to illustrate especially the "weak holes" provided at intervals to take care of the drainage the superficial area of a wall whose thickness is equal to the width of the pier. All above figures include mortar. The average brick work requires about one-tenth yard of mortar per cubic yard of finished masonry. STONE WALLS Stone walls are usually divided into two classes—rubble and ashler walls. A rubble wall is any wall made of stone in its natural state, laid as a random or course wall. Ashler walls are made of stone cut to rectangular lines. A random ashler has no particular horizontal course, as shown in Fig. 46B. Broken ashler is shown in Fig. 46A and a course ashler in Fig. 46C. The best stone work has mortar one-eighth inch to one-quar- ter inch thick. When the face of the stone is left rough the wall is known as quarry-faced ashler; if the stone is dressed a little it is pitch- face ashler. In a field stone wall the stones should be of about the same size and all of about the same color. The weathered surface should show on the wall and the stone be laid with their long di- ameters horizontal. The largest stones should be used at the base of the wall. If the back of the wall is vertical the stone should be rough and headers that run through the wall should be used. Foundations for stone walls are laid according to the same prin- ciples as govern those for brick or concrete walls. Ashler work requires one-tenth yard of mortar per cubic yard of finished masonry; rubble work requires three-tenths to four-tenths yards of mortar per cubic yard of finished Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble th
