They have been down to a packing-shed close by with a load of guayule, and are now returning for another load.
The guayule shrub is now a further source of Mexican rubber.
The only native source so far utilized is the guayule, which grows wild on the deserts of the Mexican and the American border.
Subdominants are mariola, guayule, Agave lechugilla, A. stricta or Larrea divaricata.
Then we watch the guayule being pitched by hand into crates and tightly jammed therein by being jumped on by the packers.
guayule rubber is of sufficiently good quality to be used for all but the highest class rubber goods, such as surgical appliances.
Now guayule is being cultivated and is reaped instead of being uprooted.
In 1911 seven thousand tons of guayule were imported from Mexico; in 1917 only seventeen hundred tons.
In the district we have come to visit, several Mexicans are busy gathering in a harvest of guayule.
“guayule” is a resinous rubber secured from a two-foot shrub that grows on the arid plains of Texas and Northern Mexico.
