' LUDOX SM Colloidal Silica offers extremely small particle size A n e w Du Pont colloidal silica is b e i n g o f f e r e d to researchers f o r e v a l u a t i o n . It's c a l l e d " L U D O X " S M to distinguish it from Du Pont's other c o l l o i d a l silicas. It is a v a i l a b l e in e x p e r i m e n t a l quantities now as a 1-5 p e r cent silica sol. ' ' L U D O X " SM has several unique characteristics: — Extremely small particle size (averages only 7 millimicrons, as compared with 17 millimicrons for other " L u d o x " colloidal silicas) —High surface area—400 square meters per gram —Excellent stability Du Pont's colloidal silica has found diversified applications in industry. It is presently used i n strengthening cellular f o a m r u b b e r a n d t e x tile fibers; as a n anti-slip ingredient in floor w a x e s ; a n d as t h e basis f o r soil-retard a n t treatments on textiles, p a p e r a n d p a i n t e d surfaces. " L U D O X " S M — t h e newest member o f this e v e r - e x p a n d i n g f a m i l y o f inorganic p o î y mers—shows promise as a n inorganic b i n d e r a n d in a p p l i c a t i o n s where e x t r e m e l y small particle size is important.

Industry Overtaking Agriculture Transition in Midwest brings problems, but establishment o f science-based industries promises t o offset declining agricultural employment _L HE NATION'S BREAD BASKET is under
going a far-reaching transition. Until only recently a raw-materials pro ducing area, in which many communi ties were "essentially colonial-type trad ing posts," t h e Midwest is rapidly swinging toward industrialization, de clares Charles N. Kimball, president of Midwest Research Institute. Kimball told MRI's board of trustees at its 11th annual meeting that agricul tural predominance is declining in the Great Plains region, and that b y about 1960 t h e area will have more people employed in industry than in agricul ture. "This change from rural to urban occupa fens," Kimball says, "is an evo lutionary one, which took place in the United States at large more than 35 years a g o / ' Implying that t h e transition carries with it some dangers which can b e avoided by proper planning, Kimball notes that it is possible to compensate for declining numbers of farm jobs-by increasing industrialization—"not only in the cities, but also in t h e small rural trading centers. Smaller communities are essential to our economy," Kimball
declares, "and we cannot afford agri cultural ghost towns like the abandoned Rocky Mountain mining communities." In Kimball's opinion, the Midwest's greatest hope of progressing with *he rest of the nation lies in science-based industries. And under Kimball's dirrection, the M R I staff is contributing heavily toward the realization of s"och progress. Last year, for the first time since its creation in 1945, more tfnan half of the institute's research was 'based on ideas generated by its own staff a n d presented to industry and the govern ment. • Improve t o Attract. Not the least of these programs was MRI's study of the Great Plains area's basic econosiy, from which Kimball drew some of his conclusions about the Midwest's future. Study of the factors essential to in dustrial growth and expansion revealed that t h e region badly needs to improve the physical aspects of certain of its communities in order t o attract n e w industry. In addition, the area should seek t o establish more large scale resorts and recreational facilities, and to in crease the flow of outside investment. This project is a n e w approach! to regional economic development, says Kimball, the difference lying in the application of new research, methods, followed b y a concrete step-by-step procedure to translate the research recommendations into specific action programs. α
