GUAYU 



WHEN PROPERLY CURED AND MIXED WITH OTHER COMPOUNDS

There is As IMuch Difference Between the Various Brands of Guayule 



as Between Fine Para and Shoddy 



Guayule made from old, sun exposed shrub is dead, dirty and sticky, and no amount 

 of washing will make it clean, while rubber made from freshly cut, selected shrub, has life, 

 low percentage of resin and is practically clean.
