These data have been contributed freely by the foremost engineers of the United States. In no. other way, save through the medium of this Society,--unfettered by commercialism or self-interest,--could the liberal cooperation of these men have been obtained. The Guide acknowledges the loyalty and cooperation of the men who have labored so generously to the end that its text pages shall serve usefully to advance the interests of the profession. The following members of the Society and their friends have con tributed to The Guide 1930 without compensation, except that which comes from generous public service: R. L. Beers R. G. Birkholz D. R.
