To my father, whose patient instruction and forbearing oversight during the period of carpentry apprenticeship has made possible the practical aspect of this present volume, grateful acknowledgment is made.

Acknowledgment is also made of assistance derived from the various trade magazines and from the few books on carpentry.

Credit is due Mr. Franklin G. Elwood, Peoria, for most of the excellent drawings which accompany and clarify the text. A number of the drawings were penciled by Gordon Kellar, Boston. The photographs are the work of James F. Barham, Columbia, Mo
