THE INDIA RUBBER WORLD 



[November i, 1907. 



GUAYU 



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 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. 



Guayule has come to stay and is responsible for the drop in fine Para. The largest 

 factories are using it in increasing quantities. If your competitor can undersell you, be 

 sure he is reducing his cost by using Guayule. It will pay you to experiment. 



OUR 



BRAND 



has been on the market for over 18 months and is known to be the best Guayule made 

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



OUR 



PORFIRIO 



BRAND 



is the same high grade Guayule, clean and dry, ready for compounding. 



No stocks kept on hand to deteriorate, but contracts made for regular monthly 

 shipments as capacity of our five factories will permit.
