MADERO GUAYULE INDUSTRY RESUMED. 



A 1'T1-;K three years' exile from Mexico. Alfonso, Gabriel and 

 *^ Julio Madero, brothers of former President Madero, have 

 liecn granted full amnesty by the Carranza Government and all 

 their properties have been returned, including the guayule plan- 

 tatii. ns. Two other Madero brothers, Raul and Emilo, who 

 commanded Villista forces, have not yet been granted amnesty. 

 Don Antonio left San .A.ntonio, Texas, for Mexico City early in 

 May and already the guayule factories are in operation and 

 witliin a few- months should be working to full capacity. 



The Madero interests operate eight factories having a com- 

 bined output of 350 tons of ruliber monthly, the capucit\- of the 

 Parras factory, shown by the accompanying illustration, being 

 130 tons. The black smoke from the iron stacks is not produced 

 by soft coal, but by refuse guayule wood after the rubber has 

 been extracted, which provides the bulk of the necessary fuel. 



Factory of the Compania Explotadora Coahuilense, S, A., Parras, Mexico.
