The purpose of the book is two-fold. It is intended as an aid to a teacher Of farm blacksmithing, being a source of prob lems, and suggestive Of how the work may be carried forward. In addition to being a What and How book for instructors, the author constantly had in mind its direct use by farmers as a means Of self-instruction in blacksmithing. This accounts for certain details and some repetitions. Because of its intended use as a book of self-instruction the author has taken little for granted. Farm blacksmithing is a rougher type of work than that expected of a city smith on automobile or auto truck work. The important question is: Does it fit and is it strong enough? In welding the question is not, How does it look? But Will it hold? The dimensions given on the drawings in this book are such that the work will be strong enough and Of a size in general use. The sizes should, however, be modified when individual needs require. There is real value in making these new Objects to dimensions, because only in that way will a person learn how to make duplicate parts for repairs.
