Without wide knowledge of the fact, lime is playing increasingly important roles in the lives of all Americans. In many places, air is rife with hazardous and noxious emissions. They can be greatly reduced by lime stack gas scrubbers. Naturally pure water has become rare, but even heavily polluted types can be made pure, clear, and palatable by lime treatment. Where declining crop production is due to soil acidity, or depletion of certain nutrients, the condition often can be reversed by appli­ cations of lime. Beyond those abilities for contributions to

our basic well-being, lime is of major impor­ tance in improving the quality or reducing the cost of most man-made products we need, di­ rectly or indirectly. And lime retains the construction roles it had, before developing greater ones as a chemical, in building residential and commer­ cial structures, stabilizing clay soils for roads and construction sites, etc. Truly remarkable and versatile, lime has so many advantageous uses that you may be interested in learning more about it. If so, write our Department Κ for some interesting brochures.
