The ground to be paved is thoroughly levelled and rammed down, and the quarries are laid on a bed of cement or, more economically, on plaster. The quarries may be square (Fig. 611), hexagonal (Figs. 613, 614), or octagonal (Fig. 622). This latter form is combined with little white (Fig. 621) or black (Fig. 623) squares to produce various patterns of pavement (Figs. 624, 625). In the same way diamond - shaped white (Fig. 618) or black (Fig. 620) are combined with the hexagonal shape (Fig. 619) to give the patterns represented in Figs. 616 and 617.
