Los niños del mezquite

The Cuachichiles or Guachichiles were a Mexican nomadic ethnic group of great territorial extension among all the Chichimeca peoples, they spoke a tongue that nowadays is extinct and probably belonged to the Corachol family part of the Uto-Aztec languages. 

The mesquite is a species of leguminous plants that inhabits the arid and semi-arid zones of Mexico, the tree can reach 6 to 9 meters in height, although they are also found as bushes. The wood of the mesquite is hard, so furniture and implements can be made from it. It is also used as firewood because it burns slowly and is widely used for preparing barbacoa (meat wrapped in leaves cooked underground over a slow fire with firewood) and grilled meat. Its seeds are used to produce flour, jam and wine and the leaves in infusion are a remedy for eye diseases.
