Excerpt from Practical Structural Design, Vol. 2: A Text and Reference Work for Engineers, Architects, Builders, Draftsmen and Technical Schools; Especially Adapted to the Needs of Self-Tutored Men Although the call for a second edition has been insistent it has been hard for h'm to find the time to prepare the manuscript. It is with a feeling of relief that he has finally dispatched the last Sheet. All errors which could be discovered in the' first edition have been corrected. A new chapter has been added dealing with semi-rigid frames. He desires to here express his thanks to the many friends who so kindly pointed out errors to assist in making the book a real working tool for the class of men for whom it was primarily prepared. The writer has held for years that ninety-five per cent of the work done in the design of structures could be explained to men whose knowledge of mathematics does not extend beyond that taught in High School. The Calculus is a valuable tool for those of us who can handle it, if, and when a problem arises in which it can be used advantageously. For years in the intervals of a busy professional life he managed to find time to teach in evening schools, men who entered the offices of architects, engineers and contractors at too early an age. For the same class of men he wrote articles for vocational magazines. He also prepared nume bers of draftsmen to take examinations in building design in order to receive licenses to practice architecture. That so many of his former students succeeded in the practice of structural engineer ing prompted him to collect his material and put it in book form. It is up to date and representative of good practice in the best offices. Samuel Butler says: There are plenty of things that most boys would give their ears to know; these and these only are the proper things for them to Sharpen their wits upon. It happens that a great many boys have a taste for drafting and like to watch con struction work. Under the guidance of woefully ignorant teachers, lacking practical experience outside the class room, drafting is thought to be an end; and equipped with a Certain facility in elementary drafting these unfortunate boys go forth to seek em ployment. They find it, and after laboring a few years discover that draftsmen who are merely draftsmen are truly unfortunate beings. Never enough to go around in brisk times, they are a drug on the labor market in dull times. The boys were given what they were ready to give their ears to know, but their immature judgment was at fau t and the judgment of their teachers was no better.
