THE object of this book is to present in a simple manner those well-established principles of concreting which practice has shown applicable to the manufacture of concrete blocks for building hollow walls. The theoretical and technical questions which arise in connec- tion with the industry are only considered in so far as benefit may result to the operator in the actual manufacture of blocks and their use in construction. The conclusions which have been reached are the result not only of the authors experience in actual work, but of a careful consideration of the successes and failures of a large number of operators throughout a series of years, supplemented by a careful weighing of the many articles bearing on particular phases of the subject which have been published in cement, engineering, and building magazines. To many it will appear that this book is unduly critical. For this no apology is offered. As the. industry grows much of the evil herein criticised will pass away, and it is hoped that this work may, in some measure, aid in giving to the weaknesses of the industry that prominence which can alone secure their eradication, to the end that concrete blocks may universally attain that high regard now accorded in localities where they are manufactured by really able hands. . As no allusion to patents is made in the text, the author deems it but fair to here state that very many of the designs and machines shown are protected by letters patent. To those manufacturers whose ready cooperation has been both a powerful stimulus and a substantial aid in the production of this work grateful acknowledgment is rendered. To those who have so generously furnished illustrations ofthe machines they make, and of the buildings, blocks, and special members produced in machines or molds of their manufacture, the authors thanks are due.
