tractive exterior, dictated by its location in Kansas City's cultural center, belies the "ultimate in utility" which is the keynote of Midwest Research Institute's new $1.25 million laboratory. A basic requirement of keeping costs down to $15 a square foot presented a challenge, as normal costs run from $25 to $40. Some of the means by which this goal was attained without sacrificing basic needs are set forth on page 29 A. M R I ' s basic objectives, those of developing a better balance between industry and agriculture in the Midwest and methods of processing locally produced raw materials, have been followed since M R I started operating 10 years ago in four rented rooms with a few scientists.
