Excerpt from Brick, Stone, and Plaster: Common Brickwork, Face and Ornamental Brickwork, Architectural Terra Cotta, Hollow Tile, Building Stone, Plastering The volumes of the International Library of Technology are made up of Instruction Papers, or Sections, comprising the various courses of instruction for students of the International Correspondence Schools. The original manuscripts are pre pared by persons thoroughly qualified both technically and by experience to write with authority, and in many cases they are regularly employed elsewhere in practical work as experts. The manuscripts are then carefully edited to make them suit able for correspondence instruction. The Instruction Papers are written clearly and in the simplest language possible, so as to make them readily understood by all students. Necessary technical expressions are clearly explained when introduced. The great majority of our students wish to prepare them selves for advancement in their vocations or to qualify for more congenial occupations. Usually they are employed and able to devote only a few hours a day to study. Therefore every effort must be made to give them practical and accurate information in clear and concise form and to make this infor mation include all of the essentials but none of the non essentials. To make the text clear, illustrations are used freely. These illustrations are especially made by our own Illustrating Department in order to adapt them fully to the requirements of the text. In the table Of contents that immediately follows are given the titles of the Sections included in this volume, and under each title are listed the main topics discussed.
