Ashlar Masonry consists of l)locks of stonewhich have been cut to a regular figure, genei-allyrectangular in sha])e, and laid in courses of usuallya foot or more in height. (Fig. 137.) If thecourses are not maintained at the same level con-tinuously, but are laid of stones of unequal heighthut still level and plumb, the work is called brokenashlar, shown in Fig. 138. In all ashlar work of soft material, such as [ - fe<i^^^^limestone, no stone shoukl have a length greaterthan three times its height. In harder stone thelength may l^e four or five times the height. The thickness in softstone may be once-and-one-half or twice the height; in hard stone,three times
