PREFACE

It is not the purpose of the writer to make this a book filled with technical explanations, that cannot be grasped by the average reader, but to give in the plainest language a complete and comprehensive explanation of the process of molding every class of concrete work or “cast stone” with the use of molds made from wet sand. Every care has been used to make the exact meaning clear, as the writer must assume that the reader is entirely unacquainted with the principia of this process, and wants information that will enable him to apply it to his every-day work.
