Enough examples of the formers anddies have been furnished to give a clearidea of the practice in this respect, butthey cover only a very small part of thenumber actually used. It is well withinthe truth to say that quite all forging isdone by dies, to the exclusion of all othermethods, and the exhibit of tools for thepurpose is a creditable one; indeed, it issecond to none. Mr. John Donahue, theforeman blacksmith, is an ardent advo-cate of die-work, and is constantly en-gaged in devising something new in thatline. record oi 1,900 cotter holes in brake-leverpins in ten hours.
