TH HE complete stenographic report of the 55 meetings which made up the Eleventh Annual Safety Congress would fill more than 2,000 printed pages. These Proceedings have been reduced to less than onehalf of their original volume, partly to keep the cost within a reasonable limit, and also for the convenience of the average reader who desires only a condensation of what was said and done at the Congress. The prepared papers which occupy the greater part of this book are reproduced in full or very slightly condensed. It is on the extemporaneous discussions that the editorial blue pencil has been used most freely, compressing pages into sentences and cutting out irrelevant matter entirely. To the chairmen of meetings a special apology is due, for the ruthless elimination of their graceful introduc tions and their skillful drawing out of discussion and debate, which added so much life and color to the meetings themselves. |
