(20 inches) thick, while solid brick walls need only have a depth of 33 cms. (13 inches), because, owing to the irregular shape of stones, a " bond " cannot be obtained in a thin wall. (C) Slates. Take the specimens provided and make observations on the points enumerated by the use of the following tests : (1) The... Surface.
