cut off our supplies of organic chemi cals from nprmany and other European countries leaving us unprepared for the critical days ahead. Just prior to the first exposition of chemical industries in 1914, the value of the chemical industry's products was $221 million. Today, after 4 0 years of the most astounding industrial growth ever recorded, that value has been pushed to between $22 and $23 billion annually. This is the industry which will be on display next month in Philadelphia; the business which is said to have a con stant growth rate of some 1 0 % per year compared to t h e population increase rate of 1% and the annual rise in gross national product of S7c T h a t 10% growth figure is often used but as an average it covers u p striking examples of expansion which have taken place in some of the major endchemical groups.

of interest to industrial chemists and engineers proved to be so popular, that they are being continued. A report, "Highlights of 1955 in E q u i p m e n t a n d Design," based on his own observations and supplemented by his own industrial survey, will b e given by David E. Pierce. With a background of 37 years of chemical engineering experience Pierce's views are considered to be authoritative. His experience includes associations with DuPont, -Atlantic Refining, Rohm and Haas, General Aniline, consulting and writing. He is now associated with Diamond Alkali as director of manufacturing control. H e also writes a column regularly for Industrial and Engineering Chemistry on equipment and design. Instrumentation is a science which is developing at a prodigious rate and its techniques find immediate application in every field of scientific investigation. M o d e r n analysis leans heavily on instrumental methods and may be expected to become influenced to an increasing extent by new instrumental methods.

Incorporated.
Company, a division of A i r Reduction Company, Inc. Adjacent t o A i r Reduction's National Carbide Divi sion, it receives pipeline acetylene and converts it into vinyl acetate which goes principally into polyvinyl acetate emulsions, used in adhesives, latex paints and textile finishes — and polyvinyl alcohol, used for ad hesives and textile finishes. At Calvert City, in addition to this new Air Reduc tion plant, Lummus is also building a $6,000,000 high pressure acetylene derivatives plant for General Ani line & Film Corporation which is a "first" in its field. What better examples could be given to show that Lummus is ready, willing and able to design, engineer and construct your next chemical plant. r
In the midst of a n abundance of available power natural gas, water transportation and a host of re lated chemical products, Lummus is engineering and constructing an integrated 30,000,000 lb. per year vinyl acetate plant for A i r Reduction Chemical
