Excerpt from The Location, Construction, and Maintenance of Roads Highway engineers in all parts of the Country generously con tributed material and advice. Special attention was paid' to ascertaining reasons for unusual methods, in order to avoid the publication of anything useful only in restricted localities and possibly leading to trouble if tried generally. The purpose was to furnish information Of a national value rather than an expres sion of the views Of a few individuals, who inevitably have per sonal preferences and prejudices. As each section was finished it was submitted for criticism to engineers or chemists with special knowledge of the subjects discussed, and most of the chap ters formed by combining these revised sections were sent out to other engineers for further criticism. Some of the chapters were revised a number of times before they were finally ap proved. As a consequence, although my name appears as the author on the title page, the book is rather the product Of the cooperation Of over fifty Of the leading American highway engi neers and the patient and intelligent handling Of the details of the work by Miss Isabelle Stockett, at the time chief clerk Of the American Highway Association. This book appeared originally as Part II of the 1917 Good Roads Year Book. Its wide circulation, the many references to it in technical journals, and its use as a textbook by engineering colleges, indicating that the volume had won a distinct position in technical literature, led the Directors of the American High way Association to assign the copyright to the D. Van N ostrand Company, when the Association was dissolved a few days ago. By this action the results Of the cooperative labors of so many specialists will remain available to the public.
