A guidebook for teachers, with outlines and suggestions for classroom and shop work. ACKNOWLEDGMENT This series of Typographic Text-books is the result of the splendid co-operation of a large number of firms and individuals engaged in the printing business and its allied industries in the United States of America. The Committee on Education of the United Typothetae of America, under whose auspices the books have been prepared and published, acknowledges its indebtedness for the generous assistance rendered by the many authors, printers, and others identified with this work. While due acknowledgment is made on the title and copyright pages of those contributing to each book, the Committee nevertheless felt that a group list of co-operating firms would be of interest. The following list is not complete, as it includes only those who have co-operated in the production of a portion of the volumes, constituting the first printing. As soon as the entire list of books comprising the Typographic Technical Series has been completed (which the Committee hopes will be at an early date), the full list will be printed in each volume. The Committee also desires to acknowledge its indebtedness to the many subscribers to this Series who have patiently awaited its publication. COMMITTEE ON EDUCATION, UNITED TYPOTHETAE OF AMERICA.
