THE INDIA RUBBER WORLD 



[October i, 1908. 



GUAVULE 



WHEN PROPERLY CURED AND MIXED WITH OTHER COMPOUNDS 



IS THE CHEAPEST RUBBER ON THE MARKET 



There is As Much Difference Between the Various Brands of Guayule 



as Between Tine 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. 



OUR 



PARRA^ 



BRAND 



has been on the market for several years and is known to be the best Guayule made 

 as to life, strength, purity and low percentage of resin. 



There is a large demand for a specially prepared Guayule, dry and ready for use, 

 which we have met in 



OUR

 and absolute purity is guaranteed. No mixing in of cheap compounds to bring down the 

 price. Durango rubber is nothing but Parra brand pure Guayule prepared so that anytcdy
