Vai-ious improvements in laying pavements have recently been devised, such as laying the stones dry on clay; using square stones, or stones equally wide at bottom as 556 at top; using stones alternately wider at bottom and top, and joining them with cement {Jig. 556.); paving on plates of iron, wood, or stone, or on a mass of masonry, &c. If pavements in towns did not require to be frequently lifted on account of sewers, and water and gas pipes, paving in this manner on a solid foundation would certainly be the best mode; but as things are, and even probably if pavements did not require to be frequently lifted, M'Adam's roads are found greatly preferable for all broad streets, and where care is taken to keep them clean and in complete repair. In Britain, at least, they will probably soon supersede all common pavements, and all other descriptions of common roads. 3714. Large blocks of granite (Jig. 557.) have been substituted for common-sized paving 557 ^ „ J stones ; each block is two or more feet square, nine inches deep, and channelled on the surface in imitation of common-sized paving stones. These are found to answer much better than the cast-iron plates; but they are liable to the same objection as to leverage; are difficult to replace properly; and as the raised pannels between the grooves will in time wear down to the level of the grooves, they cannot be considered so durable as common square stones, which, after all, ap
