BARRANCAS AT SOTELO 



These barrancas are west of Gramilla, in the valley of the Rio Dulce de Santiago. Here is shown a jaw- 

 bone of a common horse, buried in eolian loess 9 feet (3 meters) below the surface. When found, the 

 front end of the bone extended into the bank 7 inches (18 cm.), the rear end 3 inches (S cm.), so that 

 the angle only was exposed.
